Abstract
Twenty-three consecutive patients with metastatic non-seminomatous germ cell testicular tumours were treated with a combination of cisplatinum, vinblastine and bleomycin. Nineteen had elevated serum tumour marker levels (α-fetoprotein and βT-subunit HCG) prior to chemotherapy. In 11 of the 19, residual masses were present on the completion of induction chemotherapy despite normal serum tumour marker levels (residual mass after chemotherapy). The management of these 11 patients was based on a policy of observation rather than routine resection of residual deposits and all are currently alive (32-58 months) with ten free of active disease. Two of the eleven required additional chemotherapy when serial tumour marker levels became elevated during follow-up. Another six have been observed without further intervention and have remained well with stable or diminishing deposits. The remaining three have required resection of residual masses, in each case because of mass enlargement despite persistently negative tumour marker levels. None of the masses showed histological evidence of malignancy. A more selective approach to resection of residual masses after chemotherapy is advocated.
