[Preoperative regional radiofrequency thermochemotherapy of colorectal cancer: clinical and pathological studies].
Thirty patients with advanced colorectal cancer were treated preoperatively by combined regional radiofrequency hyperthermia and 5-FU. After the treatment, the gross tumor regressive rate was 76.7%, and the tumor integral resection rate of colorectal cancer was 92.3%. Nine patients with advanced colorectal cancer, considered unoperable and treated with thermochemotherapy, underwent a successful en bloc resection of their tumors. Marked destruction of cancer cells was observed after thermochemotherapy. Moderate-severe damage of cancer cells was observed in 76.9% of patients in the thermochemotherapy group, 33.3% in the chemotherapy group, and 42.3% in the operation group (P less than 0.005). The results indicate that the treatment is more effective in the treatment of colorectal cancer than 5-FU chemotherapy alone.
