[VAB-6 chemotherapy of advanced testicular cancers--its efficacy and limitation].
Fifteen patients with advanced testicular germ cell tumor were treated by VAB-6 chemotherapy after radical orchiectomy. CR was achieved in two (13.3%) and PR in nine (60.0%). The one, three and five year survival rates were 92.2, 64.2 and 51.4%, respectively. Nine patients (60.0%) remain with no evidence of disease (NED) after combined therapy (chemotherapy and surgery) with a median follow up of 4.3 months. We performed resection of the residual tumors and examined histologically. Out of 11 cases, four (36.3%) were with necrosis/fibrosis, two (18.2%) teratoma and five (45.5%) cancer. All of the six cases with non-cancerous tissues remain in NED. However, only two of the five cases with cancerous tissues remain in NED. We studied the NED rate based on four prognostic factors, (1) bulky abdominal diseases, (2) advanced lung diseases, (3) other metasteses, and (4) choriocarcinoma. In our analysis, advanced lung diseases and choriocarcinoma were poor prognostic factors. We should treat these poor prognostic cases initially with VP-16, ifosfamide, high doses cisplatin etc, which were used as salvaged drugs.
