Abstract
Early stage seminoma of the testis has an excellent prognosis when post-orchidectomy para-aortic and ipsilateral pelvic radiotherapy is given. However, studies on testicular lymphangiograms and the rarity of isolated pelvic nodal disease suggest that pelvic radiotherapy is not necessary, except in cases where there is the possibility of altered lymphatic drainage. We report on 27 patients with stage I and IIA seminoma treated between 1983 and 1989. Seventeen patients received radiotherapy to the para-aortic region only. There have been no pelvic recurrences. No long term complications have been encountered. We discuss the reported data which suggest that a reduced complication rate should result from the proposed field reduction. We conclude that irradiating only the para-aortic region in early stage seminoma is logical, should not increase the relapse rate and should reduce the complication rate.

Abstract
Beginning in 1981, 28 patients with advanced seminoma were treated with combination chemotherapy followed by irradiation to evaluate the possibility of improved survival using both modalities. The treatment protocol consisted of two courses of vincristine, actinomycin-D, and cyclophosphamide followed by reassessment. Those initially presenting with Stage B3 disease who achieved a complete response to two cycles of chemotherapy then underwent irradiation. All others were given a third course of chemotherapy before undergoing irradiation. The pre-radiation portion of this protocol produced a complete response rate of only 25 percent, substantially less than other, more recent, protocols. Radiation therapy produced a complete response in 69 percent of those who did not achieve a complete response from chemotherapy, increasing the complete response rate from 25 percent to 64 percent. Given this response rate to radiation therapy and the difficulty of dissection and associated morbidity with the surgical excision of postchemotherapy residual masses, the best option at this time may be observation with salvage chemotherapy and/or radiation reserved for those with disease progression.

Abstract
Fifty patients with pineal and/or suprasellar tumors were treated in the Department of Radiology, University of Tokyo, from 1975 to 1988. Histological diagnosis was obtained in 28 cases, whereas 22 patients were irradiated without pathological verification. Of the 28 patients with histological diagnosis, 11 had germinomas, 13 non-germinoma germ cell tumors, including nine teratomas, two choriocarcinomas and two embryonal carcinomas, two pineocytomas and two pineoblastomas. The treatment protocol since 1981 has been that, after 20 Gy is given with a local irradiation field, if tumor regression is marked and germinoma is highly suspected, whole brain or whole CNS irradiation is performed subsequently; otherwise, surgical intervention is performed followed by systemic chemotherapy plus radiation therapy. The five-year survival rates of histologically proven germinomas, histologically proven non-germinoma germ cell tumors, and clinically suspected germinomas by means of the above-mentioned method as well as tumor marker status were 73%, 28%, and 83%, respectively. The overall five-year survival rate was 61.3%. A statistically significant difference was found between the survival rates for the 11 cases with histologically proven germinoma and the 13 cases with non-germinoma germ cell tumors, although there was no significant difference between the survival rates for the histologically proven germinomas and the clinically suspected germinomas. Therefore radiation therapy is an effective treatment method for the management of intracranial germ cell tumors.

Abstract
A retrospective review of 69 patients with testicular seminoma, stage I and II, treated by orchiectomy and adjuvant irradiation at McGill University Hospitals from 1972 to 1987 was performed. All patients underwent either lymphangiogram or computed axial tomography scan for evaluation of retroperitoneal disease. There were 52 stage I (75%), 13 stage IIA (11%), 2 stage IIB (3%), and 2 stage IIC (Royal Marsden Hospital staging criteria). Median follow-up time was 6.2 years. The 10-year actuarial survivals were 94% and 93% for stages I and II, respectively. Only two stage I patients failed treatment, and both died from metastatic disease. Interestingly, both developed biopsy-proven metastatic brain disease and had no evidence of intra-abdominal recurrence. In stage II disease, only one patient failed the treatment. There was no serious acute toxicity and no late complications have been encountered. Radiation therapy following orchiectomy is the treatment of choice for stage I and for most stage II patients with testicular seminoma. The controversial aspects of radiographic retroperitoneal staging, the use of prophylactic mediastinal irradiation for stage II patients, and the role of surveillance only for stage I patients are discussed.

Abstract
PURPOSE The followup of 387 patients in a USA national survey of seminoma treated with radiation in 1973 and 1974 has been extended beyond 15 years to assess the long-term benefits and problems resulting from treatment. RESULTS Survival at 15 years is 83% for Stage I, 68% for Stage II; freedom from recurrence at 15 years is 93% for Stage I, 96% for Stage II; NED survival at 15 years is 80% for Stage I, 68% for Stage II; cause specific freedom from cancer death is 98% for Stage I and 97% for Stage II at 15 years. Second malignancy rates were 8% at 15 years, and observed in 14 patients versus 4.2 expected (p < .001). Deaths due to these second cancers were also increased with seven observed versus two expected (p < .01). Non-cancer intercurrent disease death occurred in 23 patients versus 7.5 expected (p < .01). The most frequent cause was cardiac death which appeared in 10 patients versus 4.4 expected (p < .05) and 8 of the 10 patients received mediastinal radiation. Two additional patients died of pulmonary fibrosis after mediastinal radiation. Mediastinal radiation correlated with all intercurrent disease and cardio-pulmonary deaths (p < .05), but not with second malignancies. With the exception of one, all patients experiencing cardiac death after mediastinal irradiation were 40 years or older at the time of treatment, with a range of 32-58 years and a mean interval to death of 9.8 years. CONCLUSIONS Recommendations for the future management of seminoma include: reducing the irradiated volume in the treatment of Stage I patients, completely eliminating mediastinal radiation in the treatment of patients with Stage IIA seminoma and treating patients with Stage IIB seminoma with chemotherapy. Radiation dose should not exceed 30 Gy for Stage I or 35 Gy for Stage IIA.

Abstract
It is standard practice when treating the pelvic and para-aortic lymph nodes of seminoma patients, to use a method to reduce the dose to the testicles due to scattered radiation. A common method is the use of lead testicular shields (clamshells). We have developed a method of immobilizing the patient while at the same time providing a stable and reproducible position for the testicular shield.

Abstract
We reviewed the clinical characteristics, treatment methods, and outcome of 26 patients presenting with seminoma arising in an undescended testis. The tumor-bearing testis was located in the iliac fossa in 17 patients and in the inguinal canal in nine. The most common presenting symptoms were pain or an enlarging mass. At diagnosis, the tumors tended to be relatively advanced, and 16 of 26 patients (62%) had nodal metastases. In addition to the paraaortic nodes, metastases were frequent to the ipsilateral iliac and inguinal nodes even in the absence of prior inguinal-scrotal surgery. Four patients had documented pelvic peritoneal tumor seeding. All patients received treatment in addition to resection of the primary tumor. Fifteen patients received radiotherapy only, 10 received chemotherapy only, and one received both modalities. At a median follow-up of 9.6 years, only one patient had relapsed. He was initially treated with radiation and after relapse was successfully salvaged with chemotherapy. The 5 and 10-year disease-free rate was 96%, and the 5 and 10-year survival rates were 92% and 79%, respectively. Appropriate treatment of seminoma arising in an undescended testis results in an excellent outcome equivalent to that observed for the more usual scrotal seminomas.

Abstract
Blood lymphocyte subsets of early breast cancer patients and of men with stage I seminoma of the testis were studied up to 6 years after radiotherapy. Similar results were obtained in the two patient groups. After a temporary decrease, the CD4-w29 or "memory" T cells recovered completely, while the CD4-45R or "naive" T cells remained decreased up to 6 years after irradiation. The number of CD8 T lymphocytes did not change during or after treatment. Because of the decrease of a subset of CD4 cells, and the unchanged values of CD8 cells, the CD4/CD8 ratio decreased significantly after irradiation, and remained lower than before treatment up to 5-6 years after radiotherapy. The number of both HLA-DR positive CD4 and HLA-DR positive CD8 T cells ("activated" T cells) increased significantly after irradiation. The natural killer (NK) cells were not affected by treatment. We propose that the recovery of the CD4 cells is limited to the CD4-w29 ("memory") population because of thymic dysfunction in older humans. The impact of the observed immune modulation on the low susceptibility for infections after local irradiation, and on putative antitumour immune responses is discussed.

Abstract
Retroperitoneal fibrosis, proved by surgical exploration and pathology, was discovered in a patient 13 years after 3,000 rad external beam cobalt retroperitoneal radiation therapy for stage I testicular seminoma. Ureteral obstruction resulted in the loss of 1 kidney, necessitating ipsilateral nephrectomy and contralateral ureterolysis. To my knowledge this is the first reported case of retroperitoneal fibrosis occurring after radiotherapy for testicular cancer.

Abstract
The exact risk of developing a second primary cancer following radiotherapy for testicular seminoma is not known. At the Northern Israel Oncology Center, between the years 1968-1988, 75 patients with early stage (I,IIA) testicular seminoma were treated by orchiectomy followed by radiation therapy. The overall 10- and 20-year survival probability was 95% and 90%, respectively. Eight patients (11%) developed nine second cancers, with a cumulative rate of one case per 1,000 years of follow-up. The second primary cancers were: two bronchogenic carcinomas, one contralateral seminoma, one thymoma, one papillary carcinoma of the thyroid, one carcinoma of the stomach, one transitional cell carcinoma of the urinary bladder, one carcinoma of the colon, and one malignant melanoma. Three of these tumors developed within the irradiated field. Five of these eight patients are alive with no evidence of recurrent cancer. We conclude that patients treated for seminoma have an increased risk of developing a second cancer. There is a need for greater awareness of this possibility. The overall prognosis remains favorable.

Abstract
Acute/subacute side effects were evaluated in 39 testicular cancer patients before infra-diaphragmatic radiotherapy, twice during therapy and 3, 6, and 12 months after treatment discontinuation. The evaluation was primarily based on questionnaires filled in by the patients. At the end of radiotherapy nausea was reported by all responding patients, and 29 patients complained of diarrhea. Two-thirds of the patients reported abdominal pain and/or meteorism, and one-half complained of retching and/or vomiting. During therapy the median weight was significantly reduced by three kilos and the median value of the performance status decreased by 20%. The hematological and biochemical toxicity was low. At the 3-month evaluation more patients complained of nausea, abdominal pain, and meteorism than before irradiation. Compared to the pretreatment situation the patients evaluated their physical condition to be reduced during treatment and at the first follow-up visit. One year posttreatment the patients had regained their physical fitness. All patients in income-producing activity were on sick leave during the period of radiotherapy and for 5 weeks (median) thereafter. In conclusion, infra-diaphragmatic radiotherapy leads to significant but reversible acute/subacute side effects lasting for a median of 9 weeks. It is hoped that better symptomatic therapy and modifications of the radiotherapy technique will reduce the side effects.

Abstract
We report a retrospective review of our experience with cisplatin-based chemotherapy in eight patients (ages 9-44 years) with histologically confirmed primary central nervous system germ cell tumors. Five patients received chemotherapy as the primary treatment, radiation therapy being administered either at completion of chemotherapy or between chemotherapy courses. Three patients received cisplatin-based chemotherapy for recurrent disease after prior radiation therapy and/or surgery. Four of five patients treated with chemotherapy at diagnosis are in complete remission at 11-14 months from diagnosis. The remaining patient twice achieved complete remission prior to dying of progressive disease 16 months after diagnosis. Two of three patients treated with chemotherapy for recurrent disease are in complete remission at 20 and 26 months; the remaining patient deteriorated after the first cycle of chemotherapy and expired six months thereafter. Overall, of seven patients evaluable for response, five achieved complete remission with chemotherapy alone, and two with chemotherapy and radiation therapy. Our results confirm previous reports of high complete remission rates utilizing cisplatin-based chemotherapy in conjunction with radiation therapy. Prospective evaluation of cisplatin-based chemotherapy followed by radiation therapy is warranted.

Abstract
Between 1968-1988, 9 patients with Stage I anaplastic seminoma were registered at this oncology center, representing 11% of 83 with testicular seminoma referred for treatment and follow-up. They ranged in age from 33-50, with a mean of 41. In all orchiectomy was performed and 8 of them received postoperative radiotherapy. After a mean of 60 months, 7 were alive with no evidence of disease, 1 had no evidence of disease and was lost to follow-up 152 months following radiotherapy, and 1 had died of metastatic disease. One of the survivors developed widespread metastatic disease but was saved by chemotherapy and is now alive and well. It is suggested that decision as to treatment of anaplastic seminoma should be based mainly on the extent of the disease, rather than the degree of differentiation.

Abstract
During 1968-1988, 6 patients with Stage I spermatocytic seminoma were registered at this oncology center. They represent 7% of a total of 83 patients referred for testicular seminoma (mean age 41 years, range 30-75). All 6 underwent high inguinal orchiectomy and 5 received postoperative radiotherapy. 1 refused any postoperative treatment. In a mean follow-up of 64 months (range 25-204), 4 patients were alive with no evidence of disease, 1 had died of ischemic heart disease without evidence of recurrence of the seminoma, and 1 was lost to follow-up after no evidence of disease was found 90 months after radiotherapy. In the light of our experience and reports in the literature, spermatocytic seminoma has a very good prognosis, although metastatic potential cannot be ruled out. Decision as to treatment should be based mainly on the stage of the disease.

Abstract
The development of modern surgical staging and effective chemotherapy regimens has markedly improved outcome of treatment of ovarian germ cell tumors. Almost all patients with completely resected tumors will survive their disease. Those with tumors other than dysgerminoma should all receive adjuvant chemotherapy. Patients with stage IA dysgerminoma can safely be observed, whereas those of higher stage should probably receive chemotherapy, although radiotherapy may be an option in selected patients, particularly older ones or those with other serious illness. Patients with advanced disease should all be treated with chemotherapy. Cisplatin-based regimens as developed for testicular cancer are more effective than VAC or VAC-type regimens. With such treatment, most dysgerminoma patients will be cured, as will many with other cell types. However, there is room for improvement in the latter group and continued investigation is appropriate.

Abstract
Infradiaphragmatic radiotherapy remains the treatment of choice for patients with stage I and II (small volume) testicular seminoma. With this approach, the disease-free survival rate exceeds 90% to 95%, and the ultimate disease-free survival rate (including salvage) is 95% to 100%. Initial therapy for patients with large-volume stage II, III, and IV disease should include multiagent systemic chemotherapy. Involved field radiotherapy is recommended for these patients following the chemotherapy, especially in patients with residual masses larger than a few centimeters. Although not used frequently in the United States, infradiaphragmatic radiotherapy is a viable treatment option for patients with clinical stage I testicular nonseminomas. Such therapy results in approximately an 85% to 90% relapse-free survival rate, with an ultimate survival rate (including salvage) approaching 100%. Initial therapy for patients with stage II or greater disease generally should include chemotherapy and/or surgery. Radiotherapy is often useful as post-chemotherapy consolidation, especially for unresectable masses. For extra-gonadal seminomas, radiotherapy is useful as definitive therapy for small-volume disease and as consolidative therapy (postchemotherapy) for more advanced disease.

Abstract
The authors reported a rare case of sellar germinoma which was misdiagnosed as nonfunctioning pituitary adenoma. A 32-year-old woman was admitted to our hospital because of amenorrhea and disturbance of left visual acuity. She had become amenorrhagic after her second delivery two years before. Neurological examination revealed she was normal except for diminished left visual acuity (Rt. = 1.2, Lt. = 0.5). The general condition was good. Urine volume and its specific gravity were within normal range. Endocrinological examination showed hyperprolactinemia (PRL 72 ng/ml) accompanied with impairment of GH, TSH, LH and FSH's reserve. Basal levels and reserve of the blood cortisol were normal. AFP and hCG were within normal range. CT scan revealed a homogenously enhanced intrasellar tumor which had a suprasellar portion (vertical length: 15 mm). T1 weighted MRI revealed low intensity tumor, and T2 weighted image revealed high intensity tumor. Sagittal MR image with gadolinium enhancement showed the pituitary gland anterior to the tumor. Transsphenoidal removal was performed. The histological diagnosis was pure germinoma. After the operation, the intracranial and spinal disseminations were disclosed. Complete neuraxis irradiation resulted in the complete remission of the tumor. Sellar germinoma without diabetes insipidus is considered to be very difficult to diagnose preoperatively. However, the authors proposed that anterior shift of the pituitary gland in sagittal MR image may be a clue to the diagnosis of sellar germinoma.

Abstract
A case of primary intracranial germinoma in the left basal ganglia treated with interstitial brachytherapy was reported. A 15-year-old boy was referred to our hospital for evaluation of right hemiparesis. A CT scan showed a slightly hyperdense mass with multiple cystic low density in the left basal ganglia. The mass was heterogeneously enhanced after intravenous administration of contrast material. T1 weighted image showed a slightly hyperintense mass with cystic components and the mass was heterogeneously enhanced with Gd-DTPA. T2 weighted MR image showed a mixed intensity mass and peritumoral edema. Stereotactic needle biopsy and implantation of 3 catheters for interstitial brachytherapy were performed simultaneously using BRW CT guided stereotactic apparatus. After the histological diagnosis was confirmed to be two cell pattern germinoma, 9 iridium-192 seeds were inserted into the catheters and maintained for 10 days to give 35Gy of irradiation at the tumor periphery. Subsequent CT scans showed marked tumor regression and the clinical symptoms were improved. Germinoma originating in the basal ganglia is rare and hard to diagnose previous to biopsy. Histological confirmation is essential before initiation of treatment because germinoma is commonly thought to be radiosensitive tumor. The interstitial brachytherapy enables selective irradiation of the tumor and actually causes no complications such as bone marrow suppression or cerebral atrophy. The neuroradiological findings, especially of CT scan and MRI, were presented and the strategy for treatment of germinoma in basal ganglia was discussed.

Abstract
From 1965 through 1988, 113 patients affected with testicular seminoma were treated at the Dept. of Radiotherapy, University "La Sapienza", Rome, Italy. Mean age of the patients was 38 years; in 70 cases tumor developed in the right testis and in 43 in the left one. In 9 patients underlying cryptorchidism was observed. All cases underwent radical orchiectomy. Histology diagnosed anaplastic seminoma in 5 cases and pure seminoma in all the other patients. Structures were involved in 7 cases. Eighty-four patients were in stage I, 20 in stage IIA, 4 in IIB, 4 in IIIA, and 1 in stage IIIB. All patients staged as I and IIA were treated with exclusive radiotherapy on paraaortic lymph nodes and inguinal and iliac lymph nodes of the involved sites (total doses: 28-35 Gy in stage I and 34-40 Gy in stage IIA). Before 1970 these patients underwent prophylactic irradiation of mediastinum and of left supraclavicular lymph nodes (total dose: 25-28 Gy). Patients in stage IIB were administered subdiaphragmatic lymph nodes irradiation with inverted-Y field (total dose: 36-45 Gy). Two cases were irradiated also on mediastinum and left supraclavicular lymph nodes, and 2 received two cycles of polychemotherapy (PVB) before irradiation. Patients in stage IIIA underwent sub-/supra-diaphragmatic irradiation (total dose: 40-45 Gy, and 40-42 Gy). The case in stage IIIB underwent palliation chemotherapy and local irradiation. All cases in stages I, IIA and IIB obtained complete remission. Three cases of the 4 in stage IIIA obtained complete remission (75%), while 1 (25%) progressed and died 8 months after diagnosis; the only case in stage IIIB progressed and died after 7 months of follow-up. Two cases in stage I recurred (2.4%), 1 in the mediastinum and 1 in the left supraclavicular lymph nodes. Both were cured with salvage radiation therapy. Toxicity related to treatment was low. Two cases in stage I developed secondary malignant neoplasms, at 4 and 34 months of follow-up, respectively.

Abstract
The case of a patient with postirradiation osteosarcoma is presented. The 20-year-old female was diagnosed as having osteosarcoma by histological examination of an open biopsy specimen. She underwent surgery for pure dysgerminoma and received adjuvant postoperative radiotherapy, 40 Gy to the pelvis and 30 Gy to the para-aortic region, 11 years ago. This case satisfied the criteria for radiation-induced osteosarcoma proposed by Cahan et al. Radiation-induced osteosarcoma is rare, but the possibility of that must be borne in mind.

Abstract
Long-term abdominal or urological morbidity and second malignancies in 289 surviving patients with infradiaphragmatic adjuvant radiotherapy (RT) for testicular cancer between 1950 and 1988 are analysed by retrospective chart review. After RT with single doses between 1.5 and 2.0 Gy and a total dose between 30 and 35 Gy, we did not observe any peptic ulcer nor other abdominal or urological long-term morbidity, except second tumours. The cumulative incidence of 16 second extratesticular malignancy was (in years after RT): 0.4% (4 years), 1.3% (9 years), 4.5% (14 years), 6.3% (19 years), 7.5% (24 years), 15.6% (29 years) and 23.6% (35 years). The ratio of observed to expected incidence of extratesticular malignancies did not differ significantly from unity; only the frequency of penile cancer (n = 2) was somewhat higher than expected. The cumulative risk of bilateral testicular cancer was 4.8% with no difference between patients with seminoma or non-seminomatous germ cell tumours. In a recent group of 128 patients with a stage I seminoma staged and treated between 1978 and 1988 by modern standard, there was no recurrence.

Abstract
Lately the role of radiotherapy in stage I seminoma of the testis has been questioned by some authors who reported on a "surveillance" strategy for these patients. Since 1980, 124 patients with seminoma of the testis have been referred to this institution; 97 of 116 patients analysed presented with stage I disease and 10 of these had elevated levels of beta HCG. A total of 64 patients were given radiotherapy after orchiectomy and 33 entered a surveillance protocol. After a median follow-up of 48 months, 3 patients in the surveillance group relapsed after 5, 13 and 49 months and 2 of the irradiated patients did so after 25 and 33 months. Elevation of beta HCG was not significant because none of these patients showed progression. A low rate of progression and excellent survival are associated with standard treatment (orchiectomy and radiotherapy) and good results have been achieved with chemotherapy in cases of relapse. A surveillance policy is not recommended in stage I seminoma because of its slower growth compared with non-seminomatous germ cell tumours (NSGCT), the absence of a specific tumour marker, the 10% risk of occult metastases and the 3-fold higher progression rate compared with irradiated patients. We suggest the use of a reduced dosage and radiation field.

Abstract
Monomelic amyotrophy developed 16 months, nine and 12 years after irradiation of the lumbosacral spinal cord for seminoma in one patient and for Hodgkin's disease in two others. In two patients, involvement was clinically limited to one leg, with a subacute course followed by plateau in the first case and with progressive worsening in the second one. In the third patient, the course was progressive with involvement of the other lower limb occurring five years later. From clinical and electrophysiological data, it seems probable that the disease process was a result of a selective injury to the lower motor neuron in the lower spinal cord.
