Abstract
Notre travail se proposait de rapporter les résultats d’une étude rétrospective, descriptive, portant sur 25 séminomes testiculaires de stade I et de préciser la place de la radiothérapie dans la prise en charge de cette entité. Entre janvier 2001 et décembre 2009, 25 patients atteints d'un séminome testiculaire de stade I ont été pris en charge au service de radiothérapie de l’institut national d’oncologie de Rabat. L’orchidectomie première a été réalisée par voie inguinale. Le bilan d’extension initial comportait un dosage de bHCG totale, d’alphafoetoprotéine, et une exploration des aires ganglionnaires sus- et sous-diaphragmatiques par une tomodensitométrie. L’irradiation adjuvante a été délivrée au moyen d’un accélérateur linéaire. L'âge médian est de 33 ans (18-52 ans). La tumeur testiculaire siégeait à droite chez 16 malades et à gauche chez les 9 autres. La radiothérapie était délivrée dans les aires ganglionnaires lomboaortiques pour 18 patients, lomboaortiques et iliaques homolatérales pour les 7 autres et ceci par deux faisceaux antéropostérieurs, délivrant une dose de 20 à 25 Gy en 10 à 14 fractions. La tolérance immédiate était excellente. La durée médiane de surveillance était de 73 mois. Vingt trois patients sont actuellement vivants, en situation de rémission complète. Un patient a rechuté au niveau pulmonaire 22 mois après la fin de sa radiothérapie. Un patient a été perdu de vue. Il n’a pas été observé de toxicité à long terme, en particulier gastro-intestinale. Aucune tumeur ou pathologie hématologique secondaire n’a été rapportée. La radiothérapie prophylactique reste le traitement adjuvant de référence des séminomes de stade I. La tolérance immédiate est satisfaisante et l’augmentation du risque de cancer secondaire est négligeable par rapport au bénéfice thérapeutique. Toutefois une surveillance armée ainsi qu’une chimiothérapie adjuvante avec un cycle de carboplatine sont aussi efficaces.

Abstract
Management of testicular seminoma has benefited from numerous advances in imaging, radiotherapy, and chemotherapy over the last 50 years leading to nearly 100% disease-specific survival for low-stage seminoma. This article examines the evaluation and management of low-stage testicular seminoma, which includes clinical stage I and IIA disease. Excellent outcomes for stage I seminoma are achieved with active surveillance, adjuvant radiotherapy, and adjuvant single-agent carboplatin. Current areas of research focus on optimizing surveillance regimens and minimizing the morbidity and long-term complications of adjuvant treatment. Radiotherapy continues to be the primary treatment option for patients with clinical stage IIa disease.

Abstract
BACKGROUND A direct association between radiotherapy dose, side-effects and secondary cancers has been described in patients with seminoma. A treatment planning study was performed in order to compare computed tomography-based traditional radiotherapy (CT-tRT) versus bone marrow-sparing intensity-modulated radiation therapy (BMS-IMRT) in patients with Stage I seminoma. MATERIAL AND METHODS We optimized in 10 patients a CT-tRT and a BMS-IMRT treatment plan to deliver 20 Gy to the para-aortic nodes. CT-tRT and IMRT consisted of anteroposterior-posterioranterior parallel-opposed and seven non-opposed coplanar fields using 16 and 6-MV photon energies, respectively. Dose-Volume Histograms for clinical target volume (CTV), planning target volume (PTV) and organs at risk (OARs) were compared for both techniques using Wilcoxon matched-pair signed rank-test. RESULTS D(mean) to CTV and PTV were similar for both techniques, even if CT-tRT showed a slightly improved target coverage in terms of PTV-D(95%) (19.7 vs. 19.5 Gy, p = 0.005) and PTV-V(95%) (100 vs. 99.7%, p = 0.011) compared to BMS-IMRT. BMS-IMRT resulted in a significant reduction (5.2 Gy, p = 0.005) in the D(mean) to the active bone marrow (ABM). The V(100%) and V(75%) of the OARs were reduced with BMS-IMRT by: ABM-V(100%) = 51.7% and ABM-V(75%) = 42.3%; bowel-V(100%) = 15.7% and bowel-V(75%) = 16.8%; stomach-V(100%) = 22% and stomach-V(75%) = 27.7%; pancreas-V(100%) = 37.1% and pancreas-V(75%) = 35.9% (p = 0.005 for all variables). CONCLUSIONS BMS-IMRT reduces markedly the dose to the OARs compared to CT-tRT. This should translate into a reduction in acute and long-term toxicity, as well as into the risk of secondary solid and hematological cancers.

Abstract
The management guide-lines about stage I seminoma (pT1 à pT4, No, Mo) recommend to perform a surveillance, an adjuvant chemotherapy based on carboplatine, or a radiotherapy. However, these options are not equivalent for side effects and relapse risk. Debates are in progress in order to simplify the surveillance protocols which remain essential because of the tumoral relapses for 15% of the patients. The occurrence of a tumoral relapse during the follow-up does not decrease the specific survival. The para-aortic 20 Gy radiotherapy is efficient on the seminoma and decreases the relapse risk. Its main side-effect is a long-term risk of secondary cancer. Carboplatine chemotherapy is also an efficient option which provides good results on the specific survival and the survival without progression. Very few studies assess the long-term side effects of chemotherapy. In the end, the therapeutic decision must be taken with the patient after informing him about all the therapeutic options.

Abstract
Seminomas are very rare tumours in children and adolescents. We describe a case of seminoma in a 15-year-old boy who was managed with orchidectomy but no adjuvant therapy. He remains relapse-free 8 years after surgery as determined by clinical, radiological and serological surveillance. This study emphasizes the uncertainty over the need for adjuvant treatment in the management of seminoma in the adolescent patient, in particular in prepubescent children.

Abstract
During the last two decades, definitive primary treatments and surveillance with definitive treatment deferred until relapse have demonstrated 98% to 99% cure rates in patients with stage I testis cancer, and these options have obtained firm positions in standard management. The development of optimal management strategies in various countries were at least partly guided by available surgical expertise in retroperitoneal lymph node dissection in the United States, and easy access to reference hospitals in densely populated countries in Western Europe that facilitated close surveillance programs; hence, treatment preferences differ on the two sides of the Atlantic. The success of both approaches is highly dependent on the skills of the practitioner, particularly of surgery and of scrutinized surveillance. As a result, local expertise and familiarity with a chosen modality has strengthened over the years, and investigators have been reluctant to embark on randomized trials designed to compare one modality with another. Such expertise with one particular technique, with the other approach being less familiar territory, has created controversy, because both physicians and patients seek evidence-based data coming from randomized clinical trials on which to make management decisions. Moreover, the reduced risk of relapse resulting from the use of radiotherapy or carboplatin in stage I seminoma and of cisplatin-based chemotherapy in stage I nonseminoma must be balanced against the potential long-term adverse effects in this population of patients with a normal life expectancy. The purpose of this review is to present the currently available data and discuss the merits and the disadvantages of the various approaches, yielding to the possible conclusion that all options appear to be equal in terms of efficacy, but that modality-associated adverse effects differ.

Abstract
Purpose To assess the possibility of reducing radiotherapy doses without compromising efficacy in the management of patients with stage I seminoma. Patients and Methods Patients were randomly assigned 20 Gy/10 fractions over 2 weeks or 30 Gy/15 fractions during 3 weeks after orchidectomy. They completed a symptom diary card during treatment and quality-of-life forms pre- and post-treatment. The trial was powered to exclude absolute differences in 2-year relapse rates of 3% to 4% (α = .05 [one sided]; 90% power). Results From 1995 to 1998, 625 patients were randomly assigned to treatment. Four weeks after starting radiotherapy, significantly more patients receiving 30 Gy reported moderate or severe lethargy (20% v 5%) and an inability to carry out their normal work (46% v 28%). However, by 12 weeks, levels in both groups were similar. With a median follow-up of 61 months, 10 and 11 relapses, respectively, have been reported in the 30- and 20-Gy groups (hazard ratio, 1.11; 90% CI, 0.54 to 2.28). The absolute difference in 2-year relapse rates is 0.7%; the lower 90% confidence limit is 2.9%. Only one patient has died from seminoma (allocated to the 20-Gy treatment group). Conclusion Treatment with 20 Gy in 10 fractions is unlikely to produce relapse rates more than 3% higher than for standard 30 Gy radiation therapy, and data on an additional 469 patients randomly assigned in a subsequent trial support and strengthen these results. Reductions in morbidity enable patients to return to work more rapidly. Prolonged follow-up is required before any inference can be made about any impact of allocated treatment on new primary cancer diagnoses.

Abstract
INTRODUCTION Seminoma accounts for about 40% of germ cell tumours of the testicle. In this retrospective analysis, we review literature concerning management of stage I seminoma. MATERIALS AND METHODS Between March 1987 and April 2001, 65 patients with stage I pure testicular seminoma received adjuvant radiotherapy with a 25 MV linear accelerator. RESULTS Median age was 33 years. Testicular tumour has been found on the right testis in 39 patients and on the left one in 24 patients. Patients have been treated using an anterior-posterior parallel pair and have received 20-25 Gy in 10-14 fractions. The target volume consisted of paraaortic, and paraaortic + homolateral iliac lymph nodes in 17 and 46 patients, respectively. Acute toxicity was mainly digestive, 38% of patients presenting nausea and vomiting. Median follow-up time was 37 months. All patients are alive in complete remission. DISCUSSION Because of good radio-sensitivity of seminoma, radiotherapy is regarded as standard adjuvant treatment (5 years relapse rate: 3-5%). Acute toxicity is dominated by moderate gastro-intestinal side effects. Secondary neoplasia represents one of the worst possible long-term complications of therapy. Waiting for ongoing randomised trials, the modern literature for seminoma reflects a trend toward lower radiation doses (20-25 Gy) and smaller treatment volumes (paraaortic field). Adjuvant chemotherapy with two courses of carboplatin, might be equivalent to radiotherapy but must be investigated in randomised trials. A surveillance policy is one of the other management options less recommended.

Abstract
Seminoma is characterized by high sensitivity to both radiation and chemotherapy. Localized recurrences in the retroperitoneum after surveillance for stage I can be treated with radiotherapy; however, multiple or large bulky retroperitoneal recurrences or systemic metastasis requires cisplatin-based chemotherapy. Salvage chemotherapy for those who recur after initial CR to induction chemotherapy is based on ifosfamide- and cisplatin-containing regimens. Incomplete response or failure after induction chemotherapy requires high-dose chemotherapy and stem cell rescue. Patients with seminoma need long-term follow-up because of the possibility of late recurrence and the risk of a second primary tumor.

Abstract
Treatment results on 695 stage I testicular cancer patients followed with surveillance are described. Seminoma (SGCT) was present in 394 patients and nonseminoma (NSGCT) in 301 patients. Relapses were detected in 155 patients (22%), in 69 patients with SGCT (17%) and 86 with NSGCT (29%). In patients with vascular invasion, relapse was detected in 54% of patients with NSGCT and 38% of patients with SGCT. Time to relapse was median 13 months (range 1 to 84 months) for SGCT and 5 months (range 1 to 171 months) for NSGCT. Forty-nine percent of relapses in SGCT patients were seen within the first year, 87% of the relapses were diagnosed within the first two years, and 98% of the relapses were detected within 5 years. The figures for NSGCT were 80%, 89% and 95%, respectively. Forty-five patients had carcinoma in situ in the contralateral testis, 62% had this together with a seminoma in the other testis. Ten patients died during the follow-up period. None of these deaths were caused by the germ cell tumour or the treatment. The overall survival for patients with stage I disease is 98.6%, and the cause specific survival 100%.

Abstract
Radiotherapy is generally accepted as a standard treatment for early-stage testicular seminoma. Relapse rates of 2% to 5% in clinical stage I and 10% to 20% in stage IIA/B (according to the Royal Marsden classification) can be achieved. Disease-specific survival reaches 100%. With such excellent cure rates, treatment-related side effects gain particular importance. Therefore, a prospective multicenter trial was initiated for radiotherapy of testicular seminoma with limited treatment portals and low total doses of irradiation. In clinical stage I, 483 patients were treated with 26 Gy to the para-aortic region only. In stage IIA, 42 patients and, in stage IIB, 18 patients received irradiation to the para-aortic and high iliac lymph nodes with 30 and 36 Gy, respectively. With a median time to follow-up of 55 months for stage I and 55.5 months for stage IIA/B, there were 18 (3.7%) and 4 (6.7%) cases of relapse in both treatment groups. Disease-specific survival was 99.6% in stage I and 100% in stage IIA/B. Acute toxicity was dominated by moderate gastro-intestinal side effects. No major late toxicity has been observed to date. Limited volume pure para-aortic treatment for stage I and para-aortic/high iliac irradiation for stage IIA/B with 26, 30 and 36 Gy, respectively, yields excellent cure rates with only moderate acute toxicity and is therefore recommended as standard treatment.

Abstract
PURPOSE A prospective observational multicenter trial was carried out to assess the incidence, pattern, and prognostic factors of radiation-induced emesis (RIE), and evaluate the use of antiemetic drugs in radiation oncology clinical practice. METHODS AND MATERIALS Fifty-one Italian radiation oncology centers took part in this trial. The accrual lasted 2 consecutive weeks, only patients starting radiotherapy in this period were enrolled. Exclusion criteria were age under 18 years, and concomitant chemotherapy. Evaluation was based on diary cards filled in daily by patients during radiotherapy and 1 week after stopping it. Diary cards recorded the intensity of nausea and any episode of vomiting and retching. Prophylactic and symptomatic antiemetic drug prescriptions were also registered. RESULTS Nine hundred thirty-four patients entered the trial, and 914 were evaluable. Irradiated sites were: breast in 211 patients, pelvis in 210 patients, head and neck in 136 patients, thorax in 129 patients, brain in 52 patients, upper abdomen in 42 patients, skin and/or extremities in 37 patients, and other sites in 97 patients. Vomiting and nausea occurred in 17.1% and 37.3% of patients, respectively, and 38.7 % patients had both vomiting and nausea. At multifactorial analysis, the only patient-related risk factor that was statistically significant was represented by previous experience with cancer chemotherapy. Moreover, two radiotherapy (RT)-related factors were significant risk factors for RIE, the irradiated site and field size. In fact, a statistically significant higher percentage of RIE was registered in upper abdomen RT and RT fields > 400 cm2. Although nonstatistically significant, patients receiving RT to the thorax and head and neck presented a higher incidence of RIE. Only a minority (14%) of patients receiving RT were given an antiemetic drug, and the prescriptions were more often symptomatic than prophylactic (9% vs. 5%, respectively). Different compounds and a wide range of doses and schedules were used; however, there is some evidence from our data that in spite of antiemetic prophylaxis, 46% of patients had vomiting, and 58% had nausea. The majority (93%) of the prophylactic group received oral 5-hydroxytriptamine receptor (5-HT3) antagonist (8 mg/day, 7 days/week). In the symptomatic group, 54% and 41% patients received 5-HT3 antagonists and metoclopramide, respectively. At multivariate analysis, no patient- or RT-related risk factor for RIE was found to influence significantly the prophylactic or symptomatic use of antiemetics. CONCLUSION Our study provided useful data on epidemiology and characteristics of RIE. Previous chemotherapy, field size, and irradiated site (upper abdomen) were the only significant prognostic factors of RIE. A remarkable incidence of RIE was found in patients submitted to thoracic and head and neck RT. With this background of knowledge, it will be possible to better plan further studies on this important problem. Moreover, the low rate of antiemetics use and the wide variety of doses and schedules employed suggest the need to reinforce the "evidence based" approach to identify the best antiemetic approach to RIE.

Abstract
PURPOSE To compare relapse rates and toxicity associated with para-aortic (PA) strip or PA and ipsilateral iliac lymph node irradiation (dogleg [DL] field) (30 Gy/15 fractions/3 weeks) for stage I testicular seminoma. PATIENTS AND METHODS Between July 1989 and May 1993, 478 men with testicular seminoma stage I (T1 to T3; no ipsilateral inguinoscrotal operation before orchiectomy) were randomized (PA, 236 patients; DL, 242 patients). RESULTS Median follow-up time is 4.5 years. Eighteen relapses, nine in each treatment group, have occurred 4 to 35 months after radiotherapy; among these, four were pelvic relapses, all occurring after PA radiotherapy. However, the 95% confidence interval (CI) for the difference in pelvic relapse rates excludes differences of more than 4%. The 3-year relapse-free survival was 96% (95% CI, 94% to 99%) after PA radiotherapy and 96.6% (95% CI, 94% to 99%) after DL (difference, 0.6%; 95% confidence limits, -3.4%, +4.6%). One patient (PA field) has died from seminoma. Survival at 3 years was 99.3% for PA and 100% for DL radiotherapy. Acute toxicity (nausea, vomiting, leukopenia) was less frequent and less pronounced in patients in the PA arm. Within the first 18 months of follow-up, the sperm counts were significantly higher after PA than after DL irradiation. CONCLUSION In patients with testicular seminoma stage I (T1 to T3) and with undisturbed lymphatic drainage, adjuvant radiotherapy confined to the PA lymph nodes is associated with reduced hematologic, gastrointestinal, and gonadal toxicity, but with a higher risk of pelvic recurrence, compared with DL radiotherapy. The recurrence rate is low with either treatment. PA radiotherapy is recommended as standard treatment in these patients.

Abstract
The following article provides a comprehensive review of male germ cell tumors; the pathology and the clinical manifestations of the tumors are discussed, as are the modern concepts of clinical staging. Patients with bulky stage II and stage III non-seminomatous germ cell tumors are treated with chemotherapy. The new international classification system has provided a very useful way to categorize these patients by prognosis. Patients with good- or intermediate-risk tumors may be treated with 3 courses of cisplatin, etoposide, and bleomycin (BEP) or 4 courses of etoposide and cisplatin (EP), and more than 90% of these patients will survive. Randomized trials have shown that, if only 3 courses of chemotherapy are to be given, the substitution of carboplatin for cisplatin and the omission of bleomycin are deleterious to outcome. Patients who still have a significant residual mass and normal markers after treatment should undergo a surgical resection of the residual tumor. Patients who are classified by the international classification system as having poor-risk tumors have about a 50% likelihood of survival, and many of these patients will require surgical resection of a residual tumor after chemotherapy. No randomized trial has proved a regimen to be superior to that of 4 courses of BEP. Currently, an ongoing trial is evaluating the effect of the early use of high-dose therapy in combination with hematopoietic rescue in patients with these types of tumors. Patients with small-volume stage II tumors are generally treated with retroperitoneal lymph node dissection (RPLND). About 25% of the patients selected for this procedure will actually have pathologically negative nodes. Those with positive nodes may elect to receive adjuvant chemotherapy (2 courses of BEP), which will almost always prevent relapse. An alternate approach for patients willing to comply with monthly follow-up is surveillance, with chemotherapy deferred until relapse is noted. About 50% of these patients will be cured with surgery (as many as 75% have microscopic disease only). With careful follow-up, those destined to relapse can be treated promptly and at a time when they have small-volume tumors and an excellent prognosis if they go on to receive chemotherapy. Patients with clinical stage I nonseminomatous germ cell tumors may also undergo RPLND, although an acceptable alternative for these patients is surveillance. The advantages and the disadvantages of each approach are discussed. The overall risk of recurrence is about 30%, but there have been patient groups defined that may vary in risk from 10% to 15% up to 50% or more. Patients with advanced seminoma are treated with chemotherapy. When this procedure is used, outcomes are favorable and all patients are either in good- or intermediate-risk groups, according to the international classification system. Patients with small-volume stage II tumors are treated with radiotherapy. Radiation is also generally used for the treatment of clinical stage I patients, although surveillance is growing in prominence as a means to treat these patients. Late effects of treatment are also discussed in this article. Ejaculatory function can be preserved in most patients who have early stage tumors and who undergo RPLND and in some patients who undergo surgery after chemotherapy. The most troubling effect of chemotherapy is the development of etoposide-induced leukemia, a unique--and fortunately rare--clinical entity.

Abstract
BACKGROUND AND PURPOSE Nausea and vomiting are frequent side effects during adjuvant abdominal radiotherapy in seminoma stage I patients. This study evaluates the efficacy and side effects of prophylactically administered tropisetron in comparison to metoclopramide. MATERIALS AND METHODS Twenty-three seminoma stage I patients who were to undergo adjuvant abdominal radiotherapy (30 Gy) were included in a prospective, randomised, open study. The patients were allocated to receive adjuvant daily tropisetron 5 mg p.o. (TROP group) (11 patients) or metoclopramide 30 mg p.o. (MET group) (12 patients), allowing an eventual dose increase to 60 mg. Evaluation was based on diary cards filled in by the patients during the treatment period. Nausea, vomiting, abdominal pain and bowel motions were assessed. RESULTS Nausea was significantly lower in the TROP group as compared with the MET group (median: 0.14 vs. 1.32; P = 0.03). Thirty percent of all patients experienced vomiting. In the TROP group one patient had a mean number of emetic events > 0 as compared with 6 patients in the MET group (P = 0.07). Two patients in the TROP group and one in the MET group discontinued therapy due to lacking control of emesis. In two further patients the doubling of the metoclopramide resulted in acceptable control of nausea/vomiting. Both drugs were generally well tolerated. CONCLUSION Seminoma stage I patients on tropisetron experienced less nausea and vomiting during abdominal radiotherapy than patients receiving metoclopramide. The costs of the former drug may, however, not justify its use as first choice anti-emetic since few patients in either group experienced severe nausea.

Abstract
The purpose of this pilot study was to evaluate the acute gastrointestinal morbidity of adjuvant radiotherapy (RT) for Stage I seminoma of the testis. Ten Stage I patients receiving para-aortic and ipsilateral pelvic nodal (dog-leg) RT provided a toxicity baseline (group A). Twenty Stage I patients, randomized to dog-leg RT or para-aortic RT (10 per group) were further randomized to received prophylactic ondansetron or expectant therapy with metoclopramide (group B). Daily patient-completed questionnaires evaluated acute toxicity. In group A (n = 10), nausea, vomiting, diarrhoea and abdominal discomfort were experienced in 90%, 80%, 70% and 90% respectively. Antiemetic and antidiarrhoeal agents were required in 70% and 10% respectively, with good response. For group B (n = 20), the overall incidences of nausea, vomiting diarrhoea and abdominal discomfort were 80%, 45%, 60% and 80% respectively. The ondansetron group experienced less nausea (P = 0.02) and less vomiting (P = 0.06). Both reduced field size and ondansetron groups appeared to have less diarrhoea (P = 0.06). The use of antiemetics in the expectant therapy groups resulted in at least a two-level reduction of toxicity grade in 86% of patients. A high incidence of lethargy, anorexia and headaches was noted for all groups. The incidence of headaches was not increased with ondansetron. Dog-leg RT for Stage I seminomas is associated with readily demonstrable gastrointestinal tract (GIT) toxicity. The number of patients in this study is too small to produce definitive results, but there appears to be reduced GIT toxicity with prophylactic antiemetics. The effect of reduced RT fields has been assessed further in the MRC randomized trial of field sizes (TE10).

Abstract
PURPOSE A prospective multicenter study was carried out to estimate the treatment outcome of radiotherapy in Stage II seminoma after the application of modern staging and radiotherapy techniques. The lower margin of the iliac field was positioned on the upper rim of the acetabulum to reduce the amount of scattered irradiation to the remaining testicle. METHODS AND MATERIALS The study was carried out in 25 centers in Germany. Patients with pure seminoma, negative AFP-values, and retroperitoneal lymph node metastases of less than 5 cm in diameter were entered into the study. All patients received a ventrodorsal opposed field irradiation of the para-aortic and the ipsilateral iliac lymph nodes. The fields extended from the top of the 11th thoracic vertebra to the top of the acetabulum. Patients in Stage IIA (lymph nodes <2 cm ) received 30 Gy, and patients with Stage IIB (lymph nodes between 2 and 5 cm) 36 Gy total dose. RESULTS 39 patients in Stage IIA and 19 patients in Stage IIB were evaluated. After a median observation time of 37 months all patients are alive and disease free. Recurrence free survival in stage IIA was 100%. Two patients in Stage IIB experienced a recurrence 10 and 17 months after the end of radiotherapy. The actuarial recurrence free survival estimate in Stage IIB was 94.1% for 1 year and 87.4% for 2 years. One recurrence in Stage IIB occurred in the mediastinum, one in the mediastinum, and one the lung. Both patients could be salvaged by chemotherapy. There were no pelvic recurrences. The treatment was well tolerated, with nausea being the most common side effect (56.9% Grade 1, 15.5% Grade 2, and 8.6% Grade 3). Diarrhea occurred in 15.5% (Grade 1), 15.5% (Grade 2), and 5.2% (Grade 3) of the patients. CONCLUSIONS The outcome of para-aortic and ipsilateral iliac irradiation in Stage IIA/B testicular seminoma is excellent with the currently available staging methods and treatment facilities. The treatment is well tolerated. The lower margin of the iliacal field can be placed at the acetabulum.

Abstract
PURPOSE To determine survival, long-term tumor control, and the effects of irradiation for stage II seminoma. MATERIALS AND METHODS Forty-five patients with stage II testicular seminoma were treated between 1966 and 1989. There were 31 patients with stage IIA disease and 14 with stage IIB disease. All patients underwent orchiectomy followed by iliac and paraaortic irradiation (median dose: 30 Gy), with 37 patients receiving prophylactic mediastinal and supraclavicular irradiation (median dose: 30 Gy). Follow-up ranged from 6 months to 20.6 years, with a median of 9.4 years. RESULTS Uncorrected survival was 98% at 5 years, 84% at 10 years, and 79% at 15 years. Survival corrected for intercurrent disease was 98% at 5, 10, and 15 years. Five patients developed recurrences with four successfully salvaged by chemotherapy and/or irradiation. There were no serious acute toxicities, and no late complications have developed from infradiaphragmatic irradiation. Supradiaphragmatic irradiation was associated with an increased risk of coronary artery disease compared to the age-matched general population. CONCLUSION Radiotherapy remains an effective treatment for stage II testicular seminoma, with a 98% adjusted survival rate at 15 years, without serious acute toxicity. Supradiaphragmatic irradiation should not be used in stage IIB patients for whom salvage chemotherapy is an option.

Abstract
The traditional adjuvant therapy for seminoma stage I is abdominal radiotherapy. Although the relapse rate ranges below 5% this treatment is challenged because concerns about adverse late effects are accumulating. Carboplatin is effective in metastatic seminoma and two pilot studies have indicated effectivity in the adjuvant setting also. As this drug is almost non-toxic in moderate doses it could be an ideal adjuvant treatment for seminoma stage I. A group of 82 patients, mean age 37.5 years (range 22-73 years), with histologically pure seminoma stage I, were given carboplatin 400 mg/m2 after orchiectomy; 60 patients received only one course of carboplatin, and 22 patients received two courses. The median time of observation is 24 months, ranging from 2 to 48 months, and 66 patients have a minimum follow-up of 1 year. There is one relapse so far. Toxicity is rather mild with no severe nausea/emesis. Mean platelet counts were 164/nl after 3 weeks and 208/nl after 4 weeks; thus, myelotoxicity was negligible. Gonadal toxicity was measured by serial follicle-stimulating hormone levels. The mean level was 11.4 U/l before treatment, and 16.2 U/l after 5 weeks, 17.3 U/l after 4 months, 14.5 U/l after 8 months and 13.5 U/l after 12 months. Thus, gonadal toxicity also appeared to be mild. In summary, the efficacies of adjuvant carboplatin and of abdominal radiotherapy seem to be identical. As carboplatin, in the dosage used, involves no severe acute side-effects and probably few late adverse effects, this regimen constitutes a promising new treatment option in seminoma patients stage I that deserves to be studied in randomized trials.

Abstract
In patients with clinical stage I non-seminomatous testicular cancer only limited information is available about the administrative problems with the surveillance programme, in particular if this policy is to be implemented in a geographically extended country with limited computerised tomography (CT) resources. One hundred and two patients with non-seminomatous testicular cancer clinical stage I and low-risk histology (MRC criteria, UK) were followed by the surveillance policy for at least 1 year after orchiectomy (median 47 months, range 21-81 months). Twenty-two patients (22%) relapsed after a median time of 5 months (range 2-18 months), 14 of them in the retroperitoneal space. Serum alpha-fetoprotein and/or human chorionic gonadotrophin were elevated in eight of the 22 relapsing patients. The progression-free and cancer-corrected survival rates were 78% and 99% respectively. Patient non-compliance did not represent a major problem, whereas the regular and adequate performance of necessary CT examinations yielded some administrative difficulties. One and 3 years after orchiectomy about 50% of the relapse-free patients had no psychological problems and were satisfied with the surveillance programme, whereas 46% reported minor and 4% major psychological distress. Despite non-negligible administrative difficulties in geographically extended countries, surveillance is feasible and safe in compliant patients with low-risk non-seminomatous testicular cancer stage I. The responsible cancer centre and the local hospitals should establish a high degree of cooperation and enable adequate follow-up examinations in these patients.

Abstract
PURPOSE Underpinned by increased confidence in cure of metastatic seminoma by chemotherapy during the past 12 years, three management strategies for Stage I seminoma have been evaluated by six collaborating centers within the Anglian Germ Cell Tumor Group. This paper evaluates the efficacy of surveillance, prophylactic radiotherapy and adjuvant chemotherapy, and discusses these differing management approaches. METHODS AND MATERIALS Patients were recruited into the study between 1982 and 1992. There was no randomization between treatment groups. Seventy-nine patients received prophylactic radiotherapy (median follow-up = 51 months), 67 patients had surveillance alone (median follow-up = 61 months) and 78 patients were treated with adjuvant single agent platinum (median follow-up = 44 months). Fifty-three of these patients received two courses of platinum (median follow-up = 51 months) and 25 patients received one course (median follow-up = 29 months, range 22-72 months). RESULTS There were 18 (27%) recurrences on surveillance, five (6%) after radiotherapy, one (1%) after two courses of adjuvant single agent platinum and none after one course of carboplatin. There was one death from testis cancer after radiotherapy and none after adjuvant chemotherapy treatments. Two patients died with drug resistant disease after relapse on surveillance. There was one death from a myocardial infarction after prophylactic radiotherapy and one death from suicide in the surveillance group. A retrospective quality of life questionnaire reviewing the incidence of early and late toxicity revealed no major differences though they suggest that those treated with one course adjuvant carboplatin had somewhat less sickness and an earlier return to work. CONCLUSION Single agent carboplatin appears well tolerated and is an effective adjuvant treatment for Stage I seminoma. A multicenter randomized trial of the different treatment modalities is required to further evaluate its use.
