Ovarian sex cord-stromal tumors in children and adolescents.

PURPOSE: To develop diagnostic standards and a risk-adapted therapeutic strategy for ovarian sex cord-stromal tumors (OSCST). PATIENTS AND METHODS: Fifty-four patients were prospectively enrolled as follow-up patients onto the German Maligne Keimzelltumoren protocols. Surgical protocols and histopathology were reviewed centrally (53 patients with complete data). Surgery included ovariectomy in 18 patients, salpingo-ovariectomy in 34 patients, and hysterectomy in one patient. Patients with stage IA tumors were followed-up at regular intervals, whereas nine patients with stage IC and six patients with stage II to III tumors were treated with cisplatin-based chemotherapy. RESULTS: International Federation of Gynecology and Obstetrics stage was IA in 27 patients, IC in 21 patients, II in three patients, and III in three patients. After a median follow-up of 59 months (range, 6 to 193 months), event-free survival +/- SD was 0.86 +/- 0.05 (47 of 54 patients) and overall survival was 0.89 +/- 0.05 (49 of 54 patients). Prognosis correlated with stage (event-free survival +/- SD: IA, 1.0 [27 of 27 patients]; IC, 0.76 +/- 0.09 [16 of 21 patients]; and II/III, 0.67 +/- 0.19 [four of six patients]; P =.02). Ten of 15 patients treated with chemotherapy, including four of six stage II to III patients, are alive after a median follow-up of 33 months. CONCLUSION: On the basis of a standardized clinical and histopathologic assessment, risk-adapted therapeutic strategies for OSCST can be evaluated. Considering our experience, we would recommend that stage IA tumors be followed up at regular intervals, whereas we would recommend cisplatin-based chemotherapy in stage IC tumors with preoperative rupture or malignant ascites, especially those with high mitotic activity. Finally, cisplatin-based chemotherapy also seems to be effective in advanced-stage tumors.

Multimodal treatment of malignant sacrococcygeal germ cell tumors: a prospective analysis of 66 patients of the German cooperative protocols MAKEI 83/86 and 89.

PURPOSE: To evaluate a multimodal approach including surgery and cisplatinum chemotherapy for treatment of children with malignant sacrococcygeal germ cell tumors (GCT) and to compare adjuvant and neoadjuvant strategies in advanced tumors. PATIENTS AND METHODS: Between 1983 and 1995, 71 patients with malignant sacrococcygeal GCT were prospectively enrolled onto the German protocols for nontesticular GCT Maligne Keimzelltumoren 83/86 and 89. Five patients who received no chemotherapy (n = 2) or nonplatinum chemotherapy (n = 2) or who did not undergo tumor resection (n = 1) were excluded from this analysis. Among the 66 patients analyzed were 14 boys and 52 girls. The median age was 17.4 months (range, 7 months to 119 months). Median follow-up was 79 months (range, 4 months to 145 months). RESULTS: Fifty-two patients presented with locally advanced stage T2 tumors, and 30 patients had distant metastases at diagnosis. Patients received a median of eight cycles (range, four to nine cycles) of cisplatinum-based chemotherapy. Thirty-five patients underwent tumor resection at diagnosis and received adjuvant cisplatinum-based chemotherapy (group A). Thirty-one patients received up-front chemotherapy followed by delayed tumor resection (group B). Group B included more metastatic tumors than group A (group B, 19 of 31 patients; group A, 11 of 35 patients, P =.01). Preoperative chemotherapy facilitated complete tumor resections (group B, 20 of 31 patients; group A, five of 35 patients, P <.001) and avoided second-look surgery. Metastases at diagnosis and completeness of the first attempt of tumor resection were significant prognostic predictors; however, metastases were not predictive for patients treated with up-front chemotherapy. At 5 years follow-up, event-free survival was 0.76 +/- 0.05 (50 of 66 patients), and overall survival was 0.81 +/- 0.05 (54 of 66 patients). Four patients died as a result of therapy-related complications, and eight patients died of their tumors. Patients with locally advanced and metastatic tumors (T2b M1) fared better with neoadjuvant treatment [overall survival: 0.83 +/- 0.09 (16 of 19 patients) versus 0.45 +/- 0.15 (five of 11 patients), P =.01]. CONCLUSION: Even locally advanced and metastatic sacrococcygeal GCT can be successfully treated with up-front cisplatinum-based chemotherapy followed by delayed but complete tumor resection.

[Cooperative therapy study of nontesticular germ cell tumors MAKEI 83 of the Society of Pediatric Oncology: analysis after 3 years]. / Die kooperative Therapiestudie für nichttestikuläre Keimzelltumoren MAKEI 83 der GPO: Analyse nach 3 Jahren.

The German Society of Pediatric Oncology has initiated in 1983 a cooperative trial for the treatment of extratesticular germ cell tumors. The treatment plan is stratified according to histology, tumor site and tumor extension. Patients with unfavourable histology received depending on prognostic factors 4 courses of either vinblastine, actinomycin D and cyclophosphamide, or the combination of vinblastine, bleomycin and cisplatinum (4 courses) completed by 4 additional courses of VP 16, ifosfamide and cisplatinum. Within 3 years, 115 patients from 37 different institutions were entered into the trial. 55 of 72 protocol patients are under observation for at least 10 months since diagnosis. The disease-free survival rate according to Kaplan-Meier is 80% (+/- 6%) at 36 months. From the interim results of this ongoing study, the following conclusions are drawn: The chemotherapeutic regimens as delivered are tolerable. Radiotherapy does not seem necessary with the exception of ovarian dysgerminomas stage I a. In coccygeal teratomas the resection of the coccygeal bone decreases the hazard of local recurrences. Using the risk adapted regimen, the prognosis for teratomas with Yolk sac origin appears as favourable as for patients with mature teratomas.

[Postpartum care of premature and newborn infants]. / Postpartuale Versorgung von Früh- und Neugeborenen.

The most important task of the physician in the delivery room is the initial and continued assessment of the premature or mature newborn. The sequence of resuscitative efforts is determined by the respiratory and circulatory changes in the baby. The procedure is summarised in an action flow sheet. If spontaneous respiration is inadequate, artificial ventilation should be begun; if the heart rate remains below 80/min cardiac massage should be instituted. There are special indications for the intubation of the trachea and the tracheal suction. In some cases catecholamines and infusions are required. One must be certain that the necessary equipment is available and properly prepared.
