RESUMEN

CONTEXT: The extent and duration of routine follow-up after paraaortic (PA) radiotherapy for stage I seminoma remain controversial in terms of efficacy, costs of technical investigations and long-term morbidity. OBJECTIVE: To analyze the current literature assessing routine follow-up after PA radiotherapy for stage I seminoma. EVIDENCE ACQUISITION: We identified all published reports on PA radiotherapy for stage I seminoma (1986-2005). We analyzed time patterns of recurrence, sites and methods of detection of relapse, and follow-up programs used. EVIDENCE SYNTHESIS: We identified 11 publications reporting outcome in 2,280 patients. Median time to recurrence in 80 relapsing patients was 15.5 months. Less than 10% of recurrences were diagnosed beyond the third year of follow-up. Isolated locoregional or distant recurrence was observed in 52 and 20 patients, respectively, without significant difference in median time to relapse. 19 out of 43 recurrences with reported method of detection of relapse were diagnosed by routine technical investigations. There was no significant difference in time to relapse between those patients followed with low volume as compared to high-volume imaging protocols. CONCLUSIONS: Our data suggest that technical investigations in posttreatment surveillance should be restricted to the first 3 years of follow-up. Furthermore, surveillance programs with a high volume of imaging apparently do not lead to earlier detection or less advanced stage at the time of relapse as compared to protocols with low volume imaging.

RESUMEN

The optimal management of clinical stage I testicular germ cell tumors remains controversial despite a cure rate of 99%. Alternatives for stage I nonseminomas include close surveillance, retroperitoneal lymph node dissection, and chemotherapy. For pure seminomas, the options are surveillance, chemotherapy, and radiation. Understanding the pros and cons of each approach may help in choosing a management plan.

RESUMEN

BACKGROUND: The aim was to investigate the use of single agent carboplatin in patients with seminoma stage IIA/B. PATIENTS AND METHODS: In a prospective phase II trial, single agent carboplatin at a dose of AUC 7 mg.min/ml every 4 weeks for three cycles in stage IIA (n=51) or four cycles in stage IIB (n=57) was given to 108 patients with previously untreated seminoma stage IIA/B. Patients with residual masses of >or=3 cm were scheduled to receive secondary surgery. RESULTS: A complete response (CR) was achieved by 88/108 (81%) patients, 17/108 (16%) achieved a partial response (PR), two of 108 (2%) showed no change, and one patient progressed. In all patients with PR the residual disease was

RESUMEN

BACKGROUND: Testicular intraepithelial neoplasia (TIN, also carcinoma in situ of the testis) is the uniform precursor of testicular germ cell cancer. Local radiotherapy to the testis with dosages of 18-20 Gy has been found to safely eradicate TIN and germ cells, too. Thus, the general assumption is that the development of invasive germ cell tumours can be prevented by this radiotherapy. PATIENTS AND METHODS: Herein, we report two patients with one-sided testicular tumour and biopsy-proven contralateral TIN. Both of them developed germ cell neoplasms in the remaining testis although local radiotherapy with 20 Gy had been applied to the testis. RESULTS: One patient developed pure seminoma 7 years after completion of radiotherapy, the other developed a combined tumour consisting of embryonal carcinoma and seminoma after 5 years. Treatment consisted of orchiectomy in each of the cases. Histologically, both had TIN in the testicular tissue surrounding the new growths. CONCLUSIONS: Pathogenetically, a small fraction of radioresistent TIN cells overcoming irradiation and progressing to full-blown germ cell cancer in the later course may be the histogenetic clue to explain these unexpected events. Other explanations, though less probable, could be technical radiotherapeutic failure due to targeting problems and a pre-existing radioresistent germ cell tumour in the irradiated testicle.

RESUMEN

A few dietary studies have found elevated testicular cancer risks for higher red meat, fat, and milk intakes and lower intakes of fruits, vegetables, and fiber. Because hormonal modulation by dietary intake of plant estrogens could affect risk of testicular cancer, we chose to explore the possible relationship between dietary phytoestrogens and testicular cancer. We conducted a hospital-based case-control study of 159 testicular cancer cases diagnosed between 1990 and 1996 and 136 adult friend-matched controls at the University of Texas M. D. Anderson Cancer Center. Amounts of phytoestrogenic compounds in foods were added to the National Cancer Institute's DietSys program and then grouped into prelignans, lignans, flavonoids, isoflavonoids, phytosterols, and coumestrol for statistical analysis, expressed per 1,000 kcal. The results of multivariate logistic regression analysis showed, after adjustment for age, education, income, ethnicity, cryptorchidism, body mass index, baldness unrelated to therapy, severe acne in adolescence, early puberty, daily fiber and fat intake, and total daily calories, no discernable monotonic increased or decreased risk estimates across quartiles of phytoestrogen intake. A U-shaped pattern was observed for lignans and coumestrol. Further evaluation of this pattern by cubic spline parameterization did fit the data, but the data were also consistent with no effect. This hypothesis-generating study does not support the premise that dietary phytoestrogens increase or decrease testicular cancer risk in young men.

RESUMEN

Postorchidectomy treatment options in patients with stage I seminoma include surveillance (reserving treatment for patients who relapse), adjuvant radiation therapy (RT), and adjuvant chemotherapy. Adjuvant retroperitoneal RT remains the treatment of choice in most centers; however, the success of surveillance in stage I nonseminomatous germ cell testis tumors, the establishment of curative chemotherapy for advanced disease, and the improvements in CT have led to re-examination of the standard treatment approach. The available data from the surveillance and adjuvant RT series suggest that almost 100% of patients with stage I testicular seminoma are cured, whichever approach is chosen. This article presents an overview of the available information on all treatment options, the pros and cons of each approach, and indications for where surveillance fits into the armamentarium of clinicians dealing with this disease.

RESUMEN

The definitive cure rate for clinical stage 1 testicular seminoma is very close to 100%, and prophylactic irradiation of the regional lymph nodes is associated with a low morbidity. Nevertheless, in recent years a "wait-and-see" policy has been proposed by some researchers. We analysed the cost/benefit ratio of radiotherapy (RT) by review of the case histories of 299 patients treated at the Department of Radiotherapy of the Istituto Nazionale per lo Studio e la Cura dei Tumori in Milan from January 1968 to December 1989. The 5-year overall survival was 99% (97.5% at 10 years), while the 10-year disease-free survival was 96%. The recurrence rate was 2.3%, but no patient relapsed in the irradiated areas. Acute toxicity was very moderate with only 4 (1.3%) serious radiation sequelae occurring 6 to 27 years after treatment. However, 9 second malignancies (3%) were observed. Lastly, we have calculated the costs for our National Health Service comparing surveillance policy and prophylactic irradiation.

RESUMEN

A 20-year-old woman with complete androgen resistance (AR; 46,XY), underwent prophylactic laparoscopic gonadectomy because of the known increased risk of gonadal malignancy. The procedure was performed with electrocoagulation using a four-puncture technique. Pelvic and abdominal inspection revealed no gonadal or metastatic tumor. The testes and attached structures were retracted medially, and the peritoneum and gonadal vessels were incised after electrocoagulation, thereby removing the gonads from the sidewalls. The gonads were individually placed into a specimen retrieval bag and removed through the suprapubic cannula site. Pathologic examination revealed an occult 8-mm seminoma in the let gonad, as well as bilateral Sertoli cell hamartomas, fallopian tube remnants, and smooth muscle tissue (mullerian remnants) adjacent to the gonads. Postoperatively, tumor markers were normal, and abdominal and pelvic computerized tomographic scans and chest radiographs were negative for possible metastatic disease. This case confirms that laparoscopic removal of testes in women with AR is effective, safe, and quick. Because of normal-appearing gonad may contain an occult tumor, we recommend using a retrieval bag, which may prevent dissemination of potentially malignant cells that may occur with unprotected morcellation.
