Standard chemotherapy for disseminated germ cell tumors (GCT) cures most patients but causes considerable acute toxicity, including treatment-related death due to septicemia during neutropenia and pulmonary fibrosis. In addition, chronic and delayed toxicities, particularly Raynaud's phenomenon, have been reported in 6% to 37% of treated patients. In an attempt to minimize the acute and chronic effects of treatment which are related primarily to vinblastine and bleomycin, a randomized trial comparing the efficacy and toxicity of vinblastine + bleomycin + cisplatin + cyclophosphamide + dactinomycin (VAB-6) and etoposide + cisplatin (EP) was conducted on 164 eligible patients with good-prognosis GCT. Seventy-nine of 82 (96%) patients receiving VAB-6 and 76/82 (93%) receiving EP achieved a complete remission (CR) with or without adjunctive surgery. Similar proportions of patients in both arms were found at surgery to have necrosis/fibrosis or mature teratoma. With a median follow-up of 24.4 months in the VAB-6 arm and 25.9 months in the EP arm, the total, relapse-free, and event-free survival distributions were similar in the two arms. Patients receiving EP experienced less emesis (P = .05), higher nadir WBC (P = .06) and platelet counts (P = .01), less magnesium wasting (P = .0001), less mucositis (P = .09), and no pulmonary toxicity. No treatment-related mortality was observed. EP is an efficacious and less toxic regimen and is recommended for good-prognosis patients with disseminated GCT.

Background. The frequency of small (≤ 1 cm) axillary lymph node negative invasive breast cancers (T1a,b N0 M0) is increasing because of wider implementation of breast cancer screening. Identification of prognostic factors for these patients has been based largely on retrospective pathology review. The authors analyzed histologic factors recorded in the original pathology reports to determine predictors of recurrence for patients with T1a,b N0 M0 breast cancer. Methods. Two hundred eighteen patients were studied. Potential prognostic factors including measured millimeter tumor size in three dimensions, histologic grade, nuclear grade, and presence or absence of lymphatic vessel invasion were documented prospectively in routine surgical pathology reports of a large community (nonuniversity based) hospital. Follow‐up was performed annually by the tumor registry. Results. With a median follow‐up of 6.9 years (range, 3–15.8 years), overall recurrence free survival was 93%. Poor nuclear grade (hazard ratio, 5.8; 95% confidence interval, 1.70–19.82; P=0.004) and lymphatic vessel invasion (hazard ratio, 4.6; 95% confidence interval, 1.34–15.61; P=0.01) were independent predictors of recurrence. Only 10% of patients had cancers with both poor nuclear grade and lymphatic vessel invasion and their 67% 7‐year recurrence free survival (RFS) rate was significantly lower than the 92% RFS rate observed for patients with one of these two factors (P=0.007) and the 99% RFS for patients with neither poor risk factor (P=0.0001). Conclusions. The combination of poor nuclear grade and lymphatic vessel invasion identifies a very small subset (10%) of patients with T1a,b N0 M0 breast cancer with a significant relapse risk that warrants consideration of adjuvant systemic therapy. However, the majority of patients with T1a,b N0 M0 breast cancer have an exceptionally good prognosis. Cancer 1995; 76:2266‐74.

The effects of chemotherapy on endocrine function were assessed in 22 previously treated patients with germ-cell tumors and compared with the endocrine function of six previously untreated patients. Baseline and stimulated serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, thyroid-stimulating hormone (TSH), prolactin, and thyroxine (T4) were obtained. Baseline LH levels were elevated in both groups of patients, whereas basal FSH levels were significantly elevated only in treated patients (P less than .001). Following gonadotropin-releasing hormone (GnRH), levels of LH (P = .051) and FSH (P = .003) were greater in treated patients than in untreated control patients. No abnormalities of thyroid function or prolactin responsiveness were observed. Patients younger than 25 years of age at the time of treatment had lower serum levels of LH and FSH following chemotherapy than patients older than 25. Evidence for partial recovery of gonadal function was present with patients treated more than 18 months before study having lower levels of LH and FSH than those patients studied less than 18 months after treatment. These data demonstrate that frequent gonadal dysfunction exists in untreated patients with germ-cell tumors and that chemotherapy induces additional injury to both Leydig cells and the germinal epithelium. Further studies with long-term follow-up are necessary to define the pattern of gonadal recovery and to assess the potential sequelae of endogenous gonadotropin hypersecretion.
