Four distinct clinicopathologic entities have been described: molar pregnancy (including complete and partial hydatidiform moles), invasive mole (chorioadenoma destruens), placental-site trophoblastic tumors, and choriocarcinoma. Although these constitute fewer than 1% of gynecologic malignancies, they are highly important to recognize because of their life-threatening potential and their high curability if treated early and by experienced centers. Its incidence varies widely among various populations, with figures as high as 1 in 120 pregnancies in some areas of Asia and South America, compared to 1 in 1200 in the United States. However, oral contraceptives and the number of sexual partners before the index pregnancy appear to double the risk of gestational trophoblastic tumors. Partial moles show a variable amount of focal trophoblastic hyperplasia and have identifiable fetal or embryonic tissues. Invasive moles (chorioadenoma destruens) have findings similar to complete moles but display a greater tendency to invade surrounding tissues. Microscopically, these tumors show no chorionic villi and are characterized by a proliferation of cells with oval nuclei and abundant eosinophilic cytoplasm. They usually arise after nonmolar abortion or a term pregnancy, but occasionally after hydatidiform mole and, in one case, after a metastatic gestational trophoblastic neoplasia. These are believed to arise from fertilization of an empty ovum by a haploid sperm that then undergoes duplication.

Since anthracyclines are the most active agents in sarcoma therapy in the metastatic setting symptoms of kidney stones buy discount septra 480mg on line, they have been used in nearly all of the adjuvant trials medicine rocks state park generic 480mg septra fast delivery, alone or in combination medications 122 generic septra 480mg overnight delivery. Most of these studies are small medications without a script buy discount septra 480 mg on line, and therefore lack the statistical power to detect small changes in overall survival. Accordingly, metaanalyses have been performed on the randomized trials for adjuvant chemotherapy in soft tissue sarcoma. In the following section the data from the individual studies and metaanalyses are examined (Table 39. Single-agent chemotherapy trials are considered first, followed by studies with combination chemotherapy. Radiation was added at the discretion of the physician for local control, then patients were randomized to doxorubicin, 60 mg/m 2 every 3 weeks for eight cycles, or to observation alone. Of 156 evaluable patients, disease-free survival was not different between the two groups, nor was there a statistically significant difference in overall survival (73. The addition of radiation therapy did not affect survival, although there was a lower rate of vaginal relapse in the group treated with radiation. There was no significant difference in local control, relapse-free survival, or overall survival in this study, although there was a trend (not statistically significant) toward better overall survival of patients with extremity sarcomas who received chemotherapy compared with the patients who did not receive chemotherapy. Thereafter, patients received doxorubicin, 70 mg/m 2 every 3 weeks for seven cycles. There was no difference in local control, relapse-free survival, or overall survival in the treatment and control arms. Seventy-eight eligible patients were randomized to observation or to doxorubicin at 35 mg/m 2 given as daily bolus doses on two consecutive days. There was no significant difference in local recurrence, disease-free survival, or overall survival in the chemotherapy arm compared with the control arm. A trend was noted toward improved disease-free survival for extremity lesions that was of borderline statistical significance (P =. Patients were then randomized to receive either doxorubicin, 60 mg/m 2, every 4 weeks for nine cycles, or to no chemotherapy. Chemotherapy was started within 6 weeks of surgery when radiation was not used for local control, or within 10 weeks when radiation was used. One hundred eighty-one patients were evaluable; at a median follow-up of 40 months, there was no difference in local control, disease-free survival, or overall survival for the evaluable patients. Survival data was also assessed for the entire 240 patient cohort; again, there was no difference in disease-free survival or overall survival. The Istituto Ortopedico Rizzoli examined a heterogeneous group of 77 patients with high-grade extremity sarcomas. Thereafter patients were randomized to receive or not receive doxorubicin, 25 mg/m 2 given daily as boluses on 3 consecutive days in a 21-day cycle, for a total of six cycles. In updated data from this study, 236 disease-free and overall survival were improved in the patients receiving chemotherapy. However, in a more recent update, 237 disease-free and overall survival benefit were not seen in the group treated with conservative surgery and chemotherapy versus conservative surgery alone. These data are difficult to analyze owing to the complex randomization scheme of the study as well as contamination of the control arm with patients receiving at least some chemotherapy (those receiving conservative surgery). At a median follow-up time of 28 months, there was no improvement in either disease-free or overall survival in the chemotherapy arm. There was a statistically insignificant improvement in local control rates in the chemotherapy arm (3 of 21 patients vs. The use of intraarterial preoperative doxorubicin in the control arm complicates comparison with the other doxorubicin adjuvant studies. At Roswell Park Memorial Institute, 19 patients with stage I uterine sarcoma were randomized to surgery alone versus surgery plus adjuvant doxorubicin, 60 to 75 mg/m2 every 4 weeks for six cycles. Six of the patients randomized to the chemotherapy arm refused randomization and were assessed as part of the control group, instead of using an intention-to-treat analysis. This combination was followed by six cycles of intermediate dose methotrexate (50 to 250 mg/kg with dose escalation). There was no effect of the immunologic adjuvant, but the overall survival at 5 years was 73%, better than the 45% seen in the historic controls. These initial data led to examination of adjuvant chemotherapy alone in a second cohort of patients with extremity sarcomas. Sixty-five patients underwent similar local control as described previously, then were randomized to observation or to the same cyclophosphamide, doxorubicin, and methotrexate regimen of the pilot study. Other patients had radioventriculograms performed confirming a subclinical decrease in cardiac ejection fraction at rest or with exercise. In all, there was an overall event rate of 46% clinical or subclinical cardiomyopathy in the 75 evaluated patients. There was no clinical congestive heart failure documented in the low-dose arm, and the decrease in cardiac ejection fraction by nuclear medicine study was less pronounced than with the high-dose arm. Analysis of this study is difficult because of the small number of patients and lack of prospective randomization for all patients. A trend toward improved disease-free survival was seen in the chemotherapy patients, but there was no statistically significant difference in overall survival. Anderson Cancer Center started one of the earliest adjuvant trials for soft tissue sarcoma. Forty-three eligible patients with trunk and extremity sarcomas were treated with local therapy (surgery and radiation) with or without chemotherapy. The chemotherapy regimen consisted of vincristine, oral cyclophosphamide, and doxorubicin every 4 weeks. After seven cycles of doxorubicin-based therapy, actinomycin D was substituted for doxorubicin in a maintenance phase to complete 2 years of chemotherapy. The initial results demonstrated poorer disease-free survival in the chemotherapy arm (76% vs. In a reanalysis of this data of the patients with truncal or extremity sarcomas, disease-free survival was improved in the chemotherapy arm (55% vs. The chemotherapy alternated between cycles of vincristine, actinomycin D, and cyclophosphamide and cycles of vincristine, doxorubicin, and dacarbazine, given at 6-week intervals for eight courses. There was no benefit in overall survival in the chemotherapy arm, and there was a high local recurrence rate, likely due to the omission of radiation in the local control phase of therapy. Disease-free survival and local control were both better in the chemotherapy arm, but overall survival was not significantly different between the two arms. Improvement in local recurrence rates was limited to patients with head, neck, and trunk sarcomas and was not observed for patients with extremity sarcomas. Some criticism has been raised as to the long accrual time of the study (11 years), inability of nearly half of patients to complete all eight cycles of chemotherapy, and the relatively large number of patients ineligible for analysis, which most commonly was due to inappropriate radiation therapy. More patients with extremity sarcomas were in the chemotherapy group, and the histology of the treated groups was different. The Italian Sarcoma Study Group reported in abstract form the only trial to date to examine an anthracycline plus ifosfamide as adjuvant therapy for extremity sarcoma. At a median follow-up of 36 months, overall survival in the chemotherapy arm was 72% compared with 55% for the control arm (P =. This investigation is promising for its use of the two most active agents against sarcoma in an appropriate cohort of patients. Review of the final data will be necessary to assess patient selection and follow-up before conclusions can be drawn concerning this data. In many of the studies, a significant proportion of patients was ineligible for analysis, raising the question of selection bias. A second example of selection bias arises from the fact that patients who are enrolled on clinical trials are healthier overall than nonrandomized patients, and survive longer, as demonstrated in the Mayo study. A number of patients with low-grade or small tumors are included in the trials described previously. Patients with high-grade sarcomas do well as long as the primary disease is small (less than 5 cm). The improved outcome with small, high-grade tumors has been incorporated into the most recent staging system for sarcoma. Furthermore, dose intensity of doxorubicin is low to moderate in many studies of adjuvant chemotherapy to date, and largely did not have growth factors such as filgrastim available. It is reasonably clear that doxorubicin and ifosfamide show dose-dependent responses, 253,254,255,256,257 and 258 and with better supportive care more intensive therapy may lead to improved survival. It is hoped that the first studies evaluating the use of adjuvant chemotherapy using an anthracycline combined with ifosfamide with growth factors 251 will give further direction to future studies in the adjuvant therapy of sarcomas. For example, to detect a 10% difference between control group and treatment group with a power of 0. Patients with extremity lesions fared better than those with other sites of disease (P =. The combined data indicated a 10% absolute improvement in overall survival (from 71% to 81%, P =. Criticism of this metaanalysis includes the fact that potentially inappropriate patients were included. Tierney and colleagues assessed 15 published studies 2 years later and converted the survival data into the odds of recurrence based on the latest available publication from each trial. In all, 1546 patients were included in the study, which showed improved survival at 2 years and at 5 years in the 13 and 11 studies eligible for analysis at each time point, respectively. Histology for each patient was recorded, but pathology review was not centralized. Analyses were stratified by trial, and hazard ratios were calculated for each trial and combined, allowing for an assessment of the risk of death or recurrence in comparison with control patients. Disease-free survival at 10 years was found to be improved from 45% to 55% and was statistically significant (P =. Local disease-free survival at 10 years also favored the chemotherapy arm, improving from 75% to 81% (P =. However, overall survival, while improving at 10 years from 50% to 54%, was not statistically significant (P =. The largest difference in overall survival was found in subgroup analysis of the 886 patients with extremity sarcomas, in which absolute overall survival was shown to increase 7% in the group receiving chemotherapy (P =. Although the most recent metaanalysis is a useful tool, it still combines studies with different designs, diverse criteria for enrollment, variations in pathologic assessment such as grading, different chemotherapeutic regimens, and different end points. In particular, only one-fourth of the specimens from the 1997 metaanalysis underwent review of tumor grade; approximately 60% were reviewed for histologic subtype. Only one small study included in the 1997 metaanalysis used ifosfamide, another active agent in sarcoma. If there is a benefit for the adjuvant use of chemotherapy, it appears modest, based on the previously mentioned data. Given no statistically significant benefit in a population of patients typically healthier than patients not enrolled on protocols, the data do not support the routine use of adjuvant chemotherapy for soft tissue sarcoma outside of the setting of a clinical trial. However, moderate to large extremity lesions represent one situation in which adjuvant chemotherapy may be considered on a case-by-case basis. The subset analysis of extremity data from the 1997 metaanalysis indicates this is one situation in which adjuvant chemotherapy can be considered. However, subset analyses are used to generate hypotheses and do not necessarily give definitive results. Publication of the more recent Italian study of epirubicin and ifosfamide as adjuvant therapy for extremity sarcomas may clarify this situation further. With clear definition of a population at high risk for metastatic disease, identification of relatively sensitive histologic subtypes of sarcoma, and use of combinations of active agents, it is hoped that future studies will delineate which clinical situations merit use of adjuvant chemotherapy. Preoperative neoadjuvant chemotherapy can make subsequent surgery easier and potentially treats micrometastatic disease earlier before acquisition of resistance. Treating with chemotherapy before surgery also leaves primary vasculature intact for drug delivery. In addition, preoperative chemotherapy can guide postoperative treatment based on pathologic review of the tissue after chemotherapy. In experimental models, preoperative chemotherapy eliminates a postoperative surge in growth of metastases noted after resection of primary tumors. Partial or complete responses were noted in over one-third of patients; not surprisingly, those patients who had a complete response by any means had a better overall survival than those who did not respond completely. Anderson Cancer Center examined preoperative chemotherapy using cyclophosphamide, doxorubicin, and dacarbazine. Only 1 of 29 patients demonstrated a clinical partial response, although liquefaction, cystic necrosis, and hemorrhage into the tumor were noted regularly in the resected specimen, with three tumors showing greater than 90% necrosis. Most patients did not elect to receive postoperative chemotherapy after surgery, and survival results from this study did not differ significantly from studies of adjuvant doxorubicin or of no chemotherapy. Assessing the response to preoperative chemotherapy in primary soft tissue sarcomas is difficult. In sum, preoperative chemotherapy is given to some patients with potentially sensitive sarcoma subtypes such as synovial sarcoma or other high-grade lesions. Nonetheless, preoperative chemotherapy may be considered during an attempt to maintain function of an extremity, with the possibility that more aggressive surgery could be performed later if needed. Selected patients have had responses that allow for a more conservative resection, avoid an amputation, or both. This infusional approach is to be differentiated from local limb perfusion, discussed later in the section Hyperthermia and Limb Perfusion. Intraarterial chemotherapy has the potential benefit of providing higher doses of chemotherapy to the limb in a first-pass effect. However, pharmacokinetic data have not shown an advantage over intravenous chemotherapy. Thereafter, a randomized trial by the same group examined preoperative intravenous versus intraarterial chemotherapy before radiation (28 Gy given over 8 days) followed by wide excision. There was no difference in local recurrence or survival between the 45 patients receiving intraarterial doxorubicin and the 54 patients receiving intravenous doxorubicin. Infusional chemotherapy has its attendant complications as well, including arterial thromboembolism, infection, gangrene, and problems with wound healing, itself requiring amputation. Pathologic fractures have been reported in patients receiving chemotherapy and relatively large doses of radiation. One study 283 reported ten major complications in 13 patients treated intraarterial chemotherapy with simultaneous radiation, emphasizing the investigational nature of this approach. Although there are situations in which such therapy should be considered, intraarterial chemotherapy at present has a limited role in the treatment of extremity sarcomas. The arterial and venous supply of the limb is connected to an extracorporeal circulation system to isolate the limb from the rest of the body. Recirculation of the blood from the limb is performed by a heart-lung machine to reoxygenate the blood. Care is taken after isolation of the limb to ensure no leakage of the circuit into the systemic circulation; technetium-labeled albumin is injected into the circuit and a probe is used over the heart to ensure isolation of the bypass circuit. A number of chemotherapeutic agents have been used for limb perfusion, such as melphalan, nitrogen mustard, actinomycin D, and doxorubicin. Surgery to remove residual tumor was performed 2 to 4 months after limb perfusion. It is difficult to compare this approach with standard chemotherapy, given the heterogeneity of patients between the two types of studies. In aggregate, the response rate does appear higher in the perfusion studies than in the infusion studies. However, isolated limb perfusion requires substantial expertise and specialized dedicated equipment. Isolated limb perfusion does appear to hold promise for at least a subset of patients who would otherwise require amputation for local control and has been approved for such patients in Europe. Studies are underway to examine the utility of regional limb infusion, which would not require bypass machines, as a simplified means of treating otherwise unresectable extremity sarcomas. Hyperthermia has been used in other ways to enhance the effects of chemotherapy in patients with locally advanced disease. Whole body hyperthermia using extracorporeal heating of blood has been combined with ifosfamide and carboplatin intravenous chemotherapy, and responses have been seen in patients with otherwise refractory small cell sarcomas. The hyperthermia used in these protocols is more aggressive than that used with limb perfusion; higher temperatures have led to a higher rate of local complications. Isolated limb perfusion has not been compared directly with simultaneous hyperthermia and chemotherapy. In sum, isolated limb perfusion and hyperthermia-enhanced chemotherapy represent novel ways of attempting to preserve function of limbs in what otherwise would be situations in which amputation would be necessary. On occasion pain is present and, less commonly, gastrointestinal bleeding, incomplete obstruction, or neurologic symptoms relating to retroperitoneal invasion or pressure on neurovascular structures are present. In one report, 289 neurologic symptoms related primarily to an expanding retroperitoneal mass were identified in 27% of patients. Important issues of differential diagnosis, particularly in the young, are the presence of a germ cell tumor or a primary retroperitoneal tumor arising from the adrenal. Most of such lesions, however, are tumors of mesenchymal origin, either benign or malignant.

Noninvasive thymomas have an intact capsule, are movable, and are easily resected, although they can be adherent to adjacent organs. In contrast, invasive thymomas involve surrounding structures and can be difficult to remove without en bloc resection of adjacent structures. Spindle-shaped cells predominate in the medullary area and likely correspond to spindle cell thymomas of the traditional classification system. Likewise, the cortex contains predominantly round to oval epithelial cells; thus, cortical thymomas probably correspond to the traditional epithelial thymoma. Predominantly cortical and cortical thymomas exhibited intermediate invasiveness and a low but definite risk of late relapse, regardless of their invasiveness. Well-differentiated thymic carcinomas were always invasive, with a high risk of relapse and death. World Health Organization Staging System for Thymic Epithelial Tumors In 1981, Masaoka et al. Myasthenia gravis is the most common autoimmune disorder, occurring in 30% to 50% of patients with thymomas. Younger women and older men usually are affected, with a female to male ratio of 2:1. Symptoms begin insidiously and result from the production of antibodies to the postsynaptic nicotinic acetylcholine receptor at the myoneural junction. Ocular symptoms are the most frequent initial complaint, eventually progressing to generalized weakness in 80%. The role of the thymus in myasthenia remains unclear, but autosensitization of T lymphocytes to acetylcholine receptor proteins or an unknown action of thymic hormones remain possibilities. Lymphoid hyperplasia, characterized by the proliferation of germinal centers in the medullary and cortical areas, is most commonly seen. The treatment of myasthenia gravis involves the use of anticholinesterase-mimetic agents [i. Thymectomy has become an increasingly accepted procedure in the treatment of myasthenia, although the indications, timing, and surgical approach remain controversial. Overall survival for myasthenia patients also is lower for patients with thymomas, but no differences were noted based on the extent of invasion present. Pure red cell aplasia is considered an autoimmune disorder and is found in approximately 5% of patients with thymomas. Examination of the bone marrow reveals an absence of erythroid precursors and, in 30%, an associated decrease in platelet and leukocyte numbers. Hypogammaglobulinemia is seen in 5% to 10% of patients with thymoma, and 10% of patients with hypogammaglobulinemia have been shown to have thymoma. Defects in both cellular and humoral immunity have been described, and many patients also have red cell hypoplasia. Treatment Thymomas are slow-growing neoplasms that should be considered potentially malignant. Complete surgical resection is the mainstay of therapy for thymomas and is the most important predictor of long-term survival. Complete surgical resection is associated with an 82% overall 7-year survival rate, whereas survival with incomplete resection is 71% and with biopsy is only 26%. Aggressive resection, including lung, phrenic nerve, pericardium, pleural implants, and pulmonary metastases, is occasionally helpful. Several studies have documented 5-year survival rates from 60% to 75% after subtotal resection and 24% to 40% after biopsy alone. Thymomas are radiosensitive tumors and, consequently, radiation has been used to treat all tumor stages as well as recurrent disease. Large variations in the amount of tumor treated and radiation delivered, however, make interpretation of these results difficult. Areas of possible microscopic disease and a small border to account for daily variability and respiratory motion are added to define the clinical and planning target volumes. Gating techniques to minimize respiratory variation and intensity-modulated radiation therapy are new techniques that can minimize the dose heterogeneity, increase total dose and fraction size, and minimize toxicity. Chemotherapy has been used with increasing frequency in the treatment of invasive thymomas. Both single-agent and combination therapy have demonstrated activity in the adjuvant and neoadjuvant settings. Doxorubicin, cisplatin, ifosfamide, corticosteroids, and cyclophosphamide all have been used as single-agent therapy. Combination chemotherapy regimens have shown higher response rates and have been used in both adjuvant and neoadjuvant settings in the treatment of advanced invasive, metastatic, and recurrent thymoma. The European Organization for Research and Treatment of Cancer noted 31% complete and 56% overall response rates with a median survival of 4. Twenty-two patients (36%) underwent surgery, with 11 (18%) achieving a complete resection (all treated with cisplatin). Nineteen patients were treated with radiotherapy, but only five patients had disease-free survivals exceeding 5 years. At surgery, 69% were completely resected and the other 31% received postoperative radiation. Twenty-five percent complete and 92% overall response rates with a remarkable 83% 7-year disease-free survival rate were reported in 12 patients at the M. Anderson Cancer Center who received cisplatin, doxorubicin, cyclophosphamide, and prednisone induction chemotherapy followed by surgical resection (80% complete) and adjuvant radiotherapy for locally advanced (unresectable) thymoma. A multiinstitutional prospective trial demonstrated a 22% complete and 70% overall response rate with a median survival of 93 months and a Kaplan-Meier 5-year failure-free survival rate of 54. Although these results compare favorably to those obtained with neoadjuvant therapy followed by surgical resection and radiation, further confirmation is needed. Currently, myasthenia actually may lead to improved survival owing to earlier detection of thymomas. Like thymoma, it is an epithelial tumor, but cytologically it exhibits malignant features. Nearly 70% of patients had symptoms of cough, chest pain, or superior vena cava syndrome. Low-grade tumors include squamous cell carcinoma, mucoepidermoid carcinoma, and basaloid carcinoma. High-grade neoplasms include lymphoepithelioma-like carcinoma and small cell, undifferentiated, sarcomatoid, and clear cell carcinomas. The optimal treatment of thymic carcinoma remains undefined, but currently a multimodality approach, including surgical resection, postoperative radiation, and chemotherapy, is recommended. Most have the ability to manufacture peptides, amines, kinins, and prostaglandins. They are aggressive tumors that invade locally and commonly metastasize to regional lymph nodes. Microscopically, the tumors exhibit a ribbon-like growth pattern with rosette formation in a fibrovascular stroma. The cells are small, round, or oval with eosinophilic cytoplasm and uniformly round nuclei. Approximately 50% of patients presented with symptoms of vague chest pain, dyspnea, and tachypnea. They frequently conform to the shape of the cardiac and mediastinal structures and are found in the anterior inferior mediastinum "draped along the diaphragm" and connected to the thymus by a small pedicle. They are most commonly seen in the anterior mediastinum and account for 10% to 15% of all primary mediastinal tumors. It is presumed that these tumors arise from malignant transformation of germ cells that have abnormally migrated during embryonic development. Benign tumors include mature teratomas and mature teratomas with an immature component of less than 50%. Malignant germ cell tumors are divided into seminomas (dysgerminomas) and nonseminomatous tumors. Nonseminomatous tumors include embryonal carcinomas, choriocarcinomas, yolk sac tumors, and immature teratomas. Mediastinal germ cell tumors are most commonly diagnosed in the third decade of life, but patients as old as 60 years of age have been reported. Many patients with benign tumors, including 50% of teratomas, are asymptomatic; however, 90% to 100% of patients with malignant tumors have symptoms of chest pain, dyspnea, cough, fever, or other findings related to compression or invasion of surrounding mediastinal structures. More than 95% of the chest films are abnormal, with almost all masses noted in the anterior mediastinum. Although careful examination of the testes, including a testicular ultrasound, should always be performed, an isolated tumor mass in the anterior mediastinum without retroperitoneal involvement is not consistent with a testicular primary tumor. It is not necessary to perform blind orchiectomy or testicular biopsy in patients with normal physical examinations and unremarkable ultrasound findings. They can be seen in any age group but most commonly occur in adults from 20 to 40 years of age. Teratomas contain elements from all three germ cell layers, with a predominance of the ectodermal component in most tumors, including skin, hair, sweat glands, sebaceous glands, and teeth. The majority of mediastinal teratomas are composed of mature ectodermal, mesodermal, and endodermal elements and exhibit a benign course. Immature teratomas phenotypically may appear as a malignancy derived from these ectodermal, mesodermal, and endodermal elements. These latter tumors behave aggressively and generally are not responsive to systemic therapy. Treatment of "benign" mediastinal teratoma includes complete surgical resection, which results in excellent long-term cure rates. The tumor may be adherent to surrounding structures, necessitating resection of pericardium, pleura, or lung. Resection of mature teratomas has been shown to result in prolonged survival with little chance of recurrence. Currently, a trial of cisplatin-based combination chemotherapy (up to 4 cycles of cisplatin, etoposide, and bleomycin or vinblastine, ifosfamide, and cisplatin, if responding) is frequently administered before attempted surgical resection. Symptoms are usually related to compression or even invasion of surrounding mediastinal structures. Twenty percent to 30% of mediastinal seminomas are asymptomatic when discovered, 143 but metastases are present in 60% to 70% of patients. Definitive conclusions regarding treatment are difficult, because several potentially curative treatment modalities exist. Seminomas are extremely radiosensitive tumors, and for many years, high-dose mediastinal radiation has been used as initial therapy, resulting in long-term survival rates of 60% to 80%. Doses as low as 20 Gy have been reported to be curative, but most reports note a significant local recurrence rate with doses of less than 45 Gy. These portals result in excessive irradiation of surrounding normal lung, heart, and other mediastinal structures. Additionally, for 20% to 40% of patients in whom local control is achieved, treatment can be expected to fail at distant sites. Pure mediastinal seminoma falls into the intermediate-risk category of the new International Staging System for Germ Cell Tumors. Even patients with visceral metastases fall into this intermediate category and, as such, have a prognosis with cisplatin-based combination chemotherapy exceeding 75% for 5-year survival. Lemarie and coworkers 140 reported that 12 of 13 patients treated experienced complete remission, with two recurrences after treatment. Cisplatin-based combination therapy achieved a complete response in three of five patients treated by Giaccione. Complete responses to treatment were noted in 85% of patients, and 83% were long-term disease-free survivors. Therefore, the recommended treatment is either supradiaphragmatic radiation or 4 cycles of cisplatin-based combination chemotherapy. The management of patients with residual radiographic abnormalities after chemotherapy is controversial. Studies have shown that the residual mass is a dense scirrhous reaction in 85% to 90% of patients, and the presence of viable seminoma is rare. Others have shown a 25% incidence of residual viable seminoma in these patients treated with chemotherapy followed by resection of residual masses larger than 3 cm. Isolated mediastinal seminoma without evidence of metastatic disease is most often managed with radiotherapy alone, with an excellent prognosis and long-term survival. Locally advanced and bulky disease may be treated initially with cisplatin-based combination chemotherapy, usually 4 cycles of cisplatin and etoposide, with radiotherapy, and followed by salvage chemotherapy (vinblastine, ifosfamide, and cisplatin) in the event of recurrence. They may occur in pure form, but in approximately one-third of cases, multiple cell types are present. Other malignant components, including adenocarcinomas, squamous cell carcinomas, and sarcomas, may be present or even represent the predominant tissue type, as usually occurs in immature teratomas. Nearly 85% of nonseminomatous germ cell tumors occur in men, with a mean age of 29 years. They are frequently invasive at the time of diagnosis, with almost 90% of patients exhibiting symptoms. These tumors carry a poorer prognosis than either pure extragonadal seminoma or their gonadal nonseminomatous counterparts, and all patients with primary mediastinal nonseminomatous germ cell tumors fall into the poor risk category of the new International Germ Cell Consensus Classification. Common metastatic sites include lung, pleura, lymph nodes, liver, and, less commonly, bone. One of the most interesting is that found in association with acute megakaryocytic leukemia. Other hematologic malignancies, such as acute myeloid leukemia, acute nonlymphocytic leukemia, erythroleukemia, myelodysplastic syndrome, malignant histiocytosis, and thrombocytosis, have all been reported. These malignancies may antedate the discovery of the germ cell tumor or occur synchronously. Solid tumors, such as embryonal rhabdomyosarcoma, small cell undifferentiated carcinoma, neuroblastoma, and adenocarcinoma have been described and occur more frequently in primary mediastinal tumors compared to gonadal germ cell neoplasms. If a tissue diagnosis is deemed necessary, fine-needle guided aspiration with cytologic staining for tumor markers may be used for confirmation. An anterior mediastinotomy provides the best exposure for open biopsy if necessary. In the past, long-term survival after treatment of nonseminomatous germ cell tumors was very rare; today, however, overall complete remission rates of 40% to 50% are obtained in most series. Persistent elevation of serum tumor markers, particularly if they begin to rise again, usually requires salvage chemotherapy. Patients found to have residual viable germ cell tumor undergo 2 additional cycles of chemotherapy. Nichols 136 reports complete remissions in 18 of 31 patients using this regimen, and other series report complete remission rates of 50% to 70%, with long-term survival rates approximating 50%. The treatment of recurrent disease is difficult, because patients with relapsing mediastinal nonseminomatous germ cell tumors do extraordinarily poorly with salvage therapy, such as vinblastine, ifosfamide, and cisplatin 151; optimal therapy has not been determined. Standard salvage chemotherapy has not proven beneficial, and few patients achieve durable remissions. High-dose chemotherapy with stem cell rescue is effective in only a few selected patients. Smooth and striated muscle, lymphatic tissue, fat, and vascular tissue all give rise to a variety of neoplasms, which may be benign or malignant. Most of these tumors also occur in other parts of the body and are discussed in detail elsewhere in the chapter on soft tissue sarcomas. Benign tumors should be completely excised, after which little chance of recurrence remains. Lipomas are the most common mesenchymal tumor of the mediastinum, representing 2% of all mediastinal neoplasms. Treatment is complete resection, and although local recurrence is possible, it is unusual. Fibromas are cured with complete surgical excision, but fibrosarcomas are usually unresectable and respond poorly to radiation and chemotherapy. Angiography is important in identifying and embolizing major feeding vessels before surgery. Treatment involves surgical resection, but this is often difficult because of adherence to surrounding structures. They compose between 19% and 39% of all mediastinal tumors 157,158 and 75% of posterior mediastinal tumors. Whereas neurogenic tumors in infants and children are frequently malignant and often present with metastatic disease, 161 in adults the majority of these tumors are benign. They occur without gender predilection at any age but are more likely in young adults. Often asymptomatic, they are solitary (except in neurofibromatosis) and found on a routine chest x-ray. They frequently arise in the paravertebral sulcus from the posterior roots of the spinal nerves at the zone of transition between the central and peripheral myelin. These tumors must be recognized to plan an appropriate operation in conjunction with a neurosurgeon. Superior vena cava syndrome, dyspnea, cough, and bony erosions, which wrongly suggest a malignant process, also have been described. Arising from the intercostal nerve sheath, the tumor is encapsulated, white or yellowish pink in color, with calcifications and cystic degeneration.

First, it highlights the relationship between distinct clinical presentations that can nevertheless evolve into one another. Second, the nomenclature emphasizes the clinical relevance of advances in the understanding of the biology of the malignant T cells. Even at this advanced stage, the distinctive tissue distribution of the malignant cells (skin infiltration, preferential localization in interfollicular regions of lymph nodes, and avoidance of bone marrow) remains evident. The overall incidence rate is approximately 4 per 1,000,000, according to data from that program. A premycotic phase with an asymptomatic, scaling erythematous macular eruption, often in sun-shielded areas. Patients may present with tumor-like lesions with central ulceration, which may undergo spontaneous regression. Systemic involvement is unusual, and cutaneous lesions may be treated with radiation therapy alone. However, lesions often relapse, even though the overall clinical course may be indolent. Patients with patches or plaques that involve less than 10% of the body surface (stage T1) are far more likely to be palliated over the long term or cured than those with the same types of lesions occupying more than 10% of the skin surface (stage T2) (. Prognosis is significantly worse for patients with cutaneous tumors (T3), although it is better for patients with less than 10% of their skin surface involved by tumors than for those with more extensive involvement (. Skin biopsies at multiple sites may be necessary to define T-stage, as lesion morphology varies from patient to patient and for different lesions from the same patient. Such problems are especially evident for early patch or plaque lesions wherein only a small fraction of the infiltrating T lymphocytes (confined exclusively to the epidermis) are actually neoplastic. This typical histopathologic pattern can be significantly modified by prior therapy, as even topical steroids can significantly alter the intensity and appearance of both the neoplastic and nonneoplastic lymphoid infiltrates. Histopathologic features of "transformation" to a high-grade lymphoma, such as an enlarged pale nucleus and prominent nucleoli or loss of normal T-cell markers, are all associated with a poorer prognosis. Skin biopsies should also be subjected to immunophenotyping to define better the identity of the benign and neoplastic cell populations present in the cutaneous lesions. Several studies have reported correlations between the immunophenotypes of the cells present in the infiltrates and stage of disease. Imaging studies (computed tomography scan or magnetic resonance imaging) are recommended at initial evaluation for those with advanced disease and during follow-up to detect enlargement of thoracic, abdominal, or pelvic nodes. In practice, biopsy of uninvolved nodal sites is uncommon; lymph nodes are subjected to biopsy either at initial staging or afterward only if they are found to be obviously enlarged on physical examination or imaging studies. Those patients with small cell infiltrates had a median survival of 40 months, and those with high-grade immunoblastic features had a median survival of only 9 months. In normal individuals, none of the more than 50 available anti-Vb monoclonal antibodies (mAbs) react with more than 2% to 5% of the circulating peripheral T cells. Such analyses have revealed a remarkable clinical heterogeneity within patients who present with T4 disease. The patient should also be asked about cutaneous integrity, temperature imbalance, fissuring, pruritus, and the use of moisturizers. Evaluation of the abdomen should be performed to detect hepatosplenomegaly, and the site, size, and number of palpable peripheral lymph nodes should be recorded. Other Studies A posteroanterior and a lateral chest radiograph should be performed in all patients. Computed tomography or magnetic resonance scans should be carried out of the chest, abdomen, and pelvis both to evaluate mediastinal, retroperitoneal, and pelvic nodes as well as to supplement physical examination of the axillary and inguinal nodes in patients with T3 and T4 disease. Such enlarged nodes should undergo biopsy (preferably by excision rather than needle sampling) to document both the presence of neoplastic T cells and the histopathologic pattern of involvement. Bone marrow evaluation is not routinely performed unless abnormalities are noted on complete blood cell count or smear. Hence, early-stage disease that is localized to the skin has an excellent chance of cure with therapies directed to the skin alone.
