Between February 1986 and July 1988 a total of 21 children aged 1 to 16 years with malignant germ cell tumours (MGCT), 18 with either metastatic disease or unresectable primary tumour, received the JEB regimen - carboplatin dosage calculated from the EDTA glomerular filtration rate (approximately 600 mg m-2), etoposide 120 mg m-2 daily x 3, and bleomycin 15 mg m-2 weekly. Primary sites were: testis (6), ovary (8), sacrococcyx (4), pineal gland (2) and vagina (1). AFP levels were elevated in 19, beta-HCG in 8. Complete marker response was achieved in 19 out of 19 evaluable patients and complete remission of measurable tumour in 16 out of 19, 12 with chemotherapy alone and 4 with the addition of surgery. A reduction in glomerular filtration rate greater than 10% occurred in 3 of 12 evaluable patients; in none greater than 20%. Sequential audiography was normal in 11 out of 12 evaluated. The regimen was myelosuppressive with WHO grade III or IV myelosuppression occurring in 12 patients. Three patients have relapsed; one with a pineal germinoma who relapsed in the abdomen six months after diagnosis, and two with sacrococcygeal teratomas and lung metastases. Two of these remain in second complete remission after further treatment. There was one death from probable bleomycin pulmonary toxicity. We conclude that this regimen is simple to administer and, apart from myelosuppression, it is well tolerated. It appears to have comparable efficacy to cisplatin-based regimens but with much less nephrotoxicity and ototoxicity and avoids the use of alkylating agents and anthracyclines.

Ninety-one patients with poor prognosis non-seminomatous germ cell tumours (NSGCT) were treated with an initial intensive chemotherapy schedule. Suitable patients fulfilled one or more of the following criteria: lymph node metastases greater than 10 cm diameter; liver, brain or bone metastases; serum HCG level greater than 50,000 IU/L; and extragonadal primary tumours. Treatment consisted of 3 cycles of bleomycin, vincristine and cisplatin (BOP) administered at 10 day intervals, followed by 3 cycles of etoposide, ifosfamide and cisplatin (VIP) at 21 day intervals. A total of 64 patients (70%) achieved a complete remission. This comprised 46 patients who received BOP/VIP only, and 18 patients who received additional chemotherapy after BOP/VIP. Of these 64 patients, 51 underwent complete surgical resection of residual masses, including 11 in whom there was evidence of teratoma with cellular atypia or non-germ cell cancer in the resected tissue. A further 9 patients had persisting unresected radiological masses in the presence of marker complete remission. The overall response rate was 80%. Currently 57 patients (63%) remain alive and free from disease progression. The median follow-up period is 90 weeks (range 24-206 weeks), with a 2 yr actuarial progression-free survival of 66% (95% c.i. 55-77%). Major toxicity was myelosuppression, occurring during the VIP arm of therapy, with a median nadir WBC of 1.1 x 10(9)/L and median platelet count of 51 x 10(9)/L. Other toxicity included peripheral neuropathy (WHO Grade 2 and 3 in 22%). We conclude that treatment results with the BOP/VIP schedule in this poor prognosis patient group are at least comparable with other schedules, and toxicity is manageable.(ABSTRACT TRUNCATED AT 250 WORDS)

From January 1976 through December 1985, methotrexate (MTX) with citrovorum factor (CF) was administered as primary treatment to 57 patients with low-risk gestational trophoblastic tumor (GTT); 51 patients were non-metastatic and 6 were metastatic GTT. The median number of courses needed to achieve biochemical remission was two (range, 1-7). Complete remission was attained in 95% of non-metastatic GTT patients with postmolar persistent trophoblastic disease, but when choriocarcinoma was histologically confirmed, this fell to 60%. The cure rate of metastatic GTT patients was only 50%. The overall remission rate with the MTX-CF combination was 84.2%. Toxicity was mild, consisting of myelosuppression and mucositis. Fifteen patients were resistant to MTX-CF, or relapsed subsequently, but they all achieved remission with chemotherapy rescue treatment (VP 16 alone, EMA/CO, CHAMOCA). Two patients required a pulmonary lobectomy. They are all still alive in biochemical remission with a median survival of 54 months. Our experience suggests that drug resistance and relapse rate seem related to a beta-HCG value higher than 10(4), an enlarged uterus with myometrial deep involvement, and a histologically confirmed diagnosis of choriocarcinoma. In conclusion, the MTX-CF combination is effective in postmolar GTT, whereas a different therapeutic approach may be considered for a "special" low-risk group of patients, on the basis of prognostic factors.

The clinical experience is reviewed in 597 Norwegian testicular cancer patients (age range: 15-45 years) treated from 1979 to 1986. During this period, computer tomography, determination of serum AFP/HCG, and cisplatin-based chemotherapy represented the modern diagnostic and therapeutic modalities. Before orchiectomy 67% of the patients had elevated AFP/HCG. An abnormal postorchiectomy serum tumour marker decrease and the presence of small vessel infiltration in the histological sections of the primary tumour significantly predicted microscopic retroperitoneal metastases in patients with clinical stage I (CSI) nonseminoma. One-third of these patients had a pathological stage II (PSII). After radiotherapy 99% of 90 seminoma patients (CSI/IIa) survived for 5 years. After cisplatin-based chemotherapy (+radiotherapy/surgery) the 5-year survival rate in 25 patients with advanced seminoma was 81%. The survival rate in 148 nonseminoma patients PSI/IIa was 100% and 87% in 94 patients with advanced nonseminoma (greater than or equal to CSIIb). Nausea, general exhaustion, myelosuppression, peripheral neuropathy, and Raynaud-like phenomena were the main acute treatment-related side effects. Slight gastrointestinal problems, slight peripheral neuropathy, Raynaud-like phenomena, and fertility disturbances were frequent late side effects. The sexual life in testicular cancer patients did not seem to be significantly impaired as compared to the normal population. Most of the patients reported no or only slight emotional problems during and after treatment. The need of thorough information at the time of diagnosis was stressed by most of them. Secondary cancer was diagnosed in 27 of 795 patients (1970-1982) (Testicular: 15; pulmonary: 4; sarcoma: 2; others: 6). Testicular cancer is today a curable malignancy. Future clinical research has to concentrate on the identification of high-risk and low-risk patients, the avoidance of overtreatment, and the reduction of toxicity (especially of long-term side effects).

Twenty-two patients with malignant chest tumor, mainly primary lung cancer, were given 73 courses of combined administration of cisplatin and bleomycin. The following results were obtained. Of 13 evaluable patients one CR and four PR, with an overall response rate of 38.5% were observed. Of seven patients who received 3 courses or more, four showed therapeutic effect, producing a response rate of 57.1%. CR was obtained in a patient with a relapse of malignant germ cell tumor showing positive HCG and AFP preoperatively. The patient survived for 445 days after the start of this treatment. Of nine patients with non-small cell lung cancer in whom therapeutic effect could be evaluated, three PR, four MR, and two PD with a response rate of 33.3% were obtained. Side effects due to cisplatin such as nausea, vomiting and impairment of renal function were all transient. Furthermore, myelosuppression caused by this chemotherapy was relatively mild compared with other chemotherapy regimens.

A 28-year old man with HCG-producing germinoma had undergone chemotherapy and radiotherapy. On admission for the fifth session of maintenance chemotherapy, he was found to be positive for hepatitis B (HB)s antigen, but negative for HBs antibody. HBs antigen had been negative during previous admissions. Since liver function was normal, the patient underwent chemotherapy. During myelosuppression after chemotherapy, liver dysfunction developed and acute HB was diagnosed. He fortunately showed seroconversion 2 months after onset. Serum immunological examinations are required for patients receiving chemotherapy.
