A phase II study of gemcitabine at fixed infusion rate of 10 mg/m2/min with or without immunotherapy in advanced renal cancer

Advanced renal cancer remains a challenge for oncologists since no treatment other than surgery has demonstrated a clear survival advantage.Gemcitabine was given to suitable patients at a fixed infusion rate of 10 mg/m2/min. Eighteen patients received concomitant immunotherapy, mostly low doses of interleukin 2 (IL2).Thirty patients were enrolled. The overall response rate was 14% (22% in the subset of patients treated with both chemotherapy and immunotherapy) with a median progression-free survival time of 4.1 + months. Toxicity was not mild, mostly fatigue, nausea and anaemia, even though not life threatening.Gemcitabine at the fixed infusion rate of 10 mg/m2/min with concomitant low doses of IL2 could be useful in the palliative treatment of symptomatic patients with renal carcinoma progressing after tyrosine kinases inhibitor.
