[Improved prognosis of intracranial germ cell tumors by intensified therapy: results of the MAKEI 89 therapy protocol].

Germ cell tumors of the central nervous system are histological identical to the extracranial tumor sites. According to the localisation germ cell tumors of the CNS are different in symptoms, diagnostic approaches, kind and location of metastases and stratification of therapy. Since 1986 patients with intracranial germ cell tumors are registered in the ongoing study for non-testicular germ cell tumors (MAKEI) of the German Society of Pediatric Oncology and Hematology, and are treated in accordance to therapy guidelines for extracranial sites. In MAKEI 89 therapy strategy was revised with a reduction of radiotherapy and an increased cumulative cisplatinum dose from 200 mg/m2 to 400 mg/m2. Patients with germinoma receive after histologic diagnosis radiotherapy consisting of 30 Gy craniospinal irradiation and 15 Gy tumorboost. Malignant non-germinoma receive after diagnosis by tumor marker in CSF and/or serum 2 courses bleomycin 15 mg/m2 day 1-3, Etoposide 150 mg/m2 day 1 + 2 and cisplatinum 20 mg/m2 days 4-8 (BEP), continued by 2 courses Vinblastine 3 mg/m2 day 1 + 2, Ifosfamide 1500 mg/m2 days 1-5 and cisplatinum 20 mg/m2 days 1-5 (VIP), followed by 30 Gy craniospinal irradiation and 20 Gy tumor boost. In teratoma first line therapy is complete resection. In incomplete resected cases adjuvant chemotherapy according to histological grading is administered. Until 31st January, 1993 101 patients (pts) were registered, containing 69 protocol pts. Diagnosis in protocol pts was teratoma in 8 cases, 2 pts died postnatal because of extended disease, 2/8 pts relapsed, but were salvaged by chemotherapy. 40 pts offered germinomas.(ABSTRACT TRUNCATED AT 250 WORDS)

[Prognosis and quality of life following tumors in the pineal region in childhood].

At the department of neurosurgery and pediatrics of the University Hospital of Hamburg 18 children with pineal region tumors were treated by surgical removal and craniospinal axis radiation. Total or nearly total removal was achieved in 13 cases. In case of astrocytoma and pineocytoma no further treatment was performed. Children with germinoma, pinealoblastoma and teratoma underwent craniospinal axis radiation postoperatively. All children thus treated, except one with a highly malignant pinealoblastoma, are so far relapse-free. Two patients with germinoma and two patients with malignant mixed teratoma, which showed extensive growth and/or primary metastases already at admission died. Subject of this report is an assessment of quality of live and a comprehensive follow-up of neurological, endocrinological and psychointellectual conditions of the surviving children. Parent assessment of quality of life indicate for all but two children life quality as excellent or reasonable. One child was disabled by severe motor dysfunction, visual defects and convulsions. In two children minor neurological handicap was found. Minor oculomotor dysfunction was the most frequent neurological finding. Four children showed endocrinopathies. In three cases tumor associated panhypopituitarism persisted after treatment. Only one child developed growth hormone and ADH deficit succeeding surgery and craniospinal axis radiation. The children were examined with a neuropsychological test-battery. In four children severe neuropsychological deterioration was found. Three children showed no remarkable deterioration, five only minor or moderate psychological deficits. Generally verbal intelligence seemed to be on average, non-verbal intelligence and ability for concentration showed decreased scores.

Intracranial melanoma metastases: surgical treatment and follow-up of 18 patients.

Eighteen patients with operated cerebral metastases from malignant melanoma were followed-up. There was no operative death and in general the patients' quality of life was improved. The results suggest that operation of a cerebral metastasis prolongs the survival of the patient if no other cerebral lesions develop. Every operatively accessible recurrence or new metastasis should be operated on, if the general condition of the patient allows it.
