The regimen of gemcitabine and cisplatin combined with radio frequency hyperthermia for advanced non-small cell lung cancer: A phase II study

PURPOSE: This phase II randomised trial was designed to evaluate the therapeutic efficacy and feasibility of radio frequency regional hyperthermia in combination with chemotherapy for patients with advanced non-small lung cancer (NSCLC). METHODS: Eighty patients with pathologically proven advanced NSCLC, were enrolled and divided into two groups. Group A patients were treated by radio frequency regional hyperthermia in combination with the regimen of gemcitabine and cisplatin (GP). Group B patients were treated with the GP regimen alone. RESULTS: In group A, one patient achieved a complete response (CR), 18 achieved a partial response (PR), 18 achieved a stable disease and three experienced a progression of the disease. Thirty-three patients had a positive Clinical Benefit Response (CBR). In group B, no patient achieved CR, 17 achieved PR, 19 achieved a stable disease and four experienced a progression of the disease. Nineteen patients had a positive CBR. Significant differences between the two groups were observed for the CBR (P < 0.05), but not for RR. Major toxicities included bone marrow depression, nausea, vomiting, without significant differences between the two groups (P > 0.05). CONCLUSIONS: Radio-frequency regional hyperthermia in combination with chemotherapy (GP) is a safe, well tolerated, and effective therapeutic modality for patients with advanced NSCLC. The addition of hyperthermia improved quality of life.
