Effect of recombinant mutant human tumor necrosis factor on advanced gastric cancer: randomized controlled study LIU Xing, ZHANG Xiang-fu, LU Hui-shan, WU Xin-yuan, HUANG Chang-ming, WANG Chuan, GUAN Guo-xian Abstract Objective To observe the therapeutic effect of recombinant mutant human tumor necrosis factor (rmhtnf) combined with general chemotherapy on advanced gastric cancer, and to investigate the toxicity of rmhtnf. Methods A prospective randomized case-controlled study, in which 64 patients with advanced gastric cancer were recruited, was carried out. The patients were randomly divided into rmhtnf (40 patients) and chemotherapy groups (24 patients). Both the groups received chemotherapy consisting of two 21-day cycles of 5-FU 500 mg/ m 2 (day 1 5), ADM 40 mg/ m 2 (day 1), and MMC 6 mg/ m 2 (day 1). During the chemotherapy, rmhtnf (4 10 6 U/m 2 ) was given to the rmhtnf group by injection from the 1st to 7th day, and the 11th to 17th day. According to the WHO criteria, the clinical response was classified as complete response (CR), partial response (PR), minimal response (MR), stable disease (SD), and progression disease (PD). The response rate (CR+PR) and clinical benefit rate (CR+PR+MR+SD) were calculated. The toxicity of rmhtnf was graded using the WHO scale for acute and subacute toxicity. Results Of the 64 patients, 2 in the chemotherapy group dropped out of the trial, the outcomes of other 62 patients were evaluated. In the rmhtnf group, 7 patients achieved PR, the response rate was 17.5% (7/40), which was higher than that in the chemotherapy group [4.5% (1/22)], but without significant difference (P=0.144). The clinical benefit rate in the rmhtnf group was significantly higher than that in the chemotherapy group [80.0% (8/17) vs. 54.5% (12/22), P=0.036]. In the rmhtnf group, the Karnofsky score increased significantly after the treatment (after treatment 87.2±7.5 vs. before treatment 83.0±8.0, P=0.001), whereas it did not changed significantly in the chemotherapy group (84.1±8.0 vs. 83.2±7.8, P>0.05). The Karnofsky score after the treatment in the rmhtnf group was significantly higher than that in the chemotherapy group (P=0.049). The toxicity of the rmhtnf was evaluated in all the 64 patients. The most frequent adverse reactions to rmhtnf included pain, hardening, swelling, and redness at the site of injection, chill, ostealgia and myosalgia, fever, and cold-like symptoms, all of which were mild and tolerable. Conclusions Chemotherapy combined with rmhtnf can improve the short-term outcomes, health status, and quality of life of patients with advanced gastric cancer. The adverse reactions to the local injection of rmhtnf are mild and tolerable.
