The phase II evaluation of Bacillus Calmette-Guerin plus megestrol acetate in patients with metastatic renal adenocarcinoma.

The case is reported of a patient with pulmonary metastases from a renal adenocarcinoma who experienced subjective improvement and objective tumor regression on Bacillus Calmette-Guerin (BCG) and megestrol acetate therapy. In a subsequent Phase II trial, no objective responses were noted among 15 patients treated with megestrol acetate (160 mg/day X 56 days) and BCG (five immunizing doses intradermally, every 2 weeks X 5). It is concluded that this treatment regimen is not clinically useful in patients with metastatic renal adenocarcinoma.
