When the hypoxic V79 cells were exposed to γ-ray and CMNa, the cell surviving fraction decreased markedly as compared with radiation alone. The sensitizer enhancement ratio (SER) value was 1. 26-2. 32. When the mice bearing Lewis . B16 melanoma or EMT6 tumors were treated with single dose or fractionated radiation (with or without CMNa) or with antitumor agents (with or without CMNa) the tumor increasing velocity slowed down and the days of tumor growth delay increased significantly when CMNa was given simultaneously.In 96 cases of lung cancer and 80 cases of esophageal cancer patients treated with routine chemotherapy or radiotherapy combined with CMNa, the percentage of CR+PR increased significantly. These results showed that CMNa may be an effective radio- and chemo-sensitizer.展开更多

Methods: The effects of CMNa combined with paclitaxel and carboplatin on elevated CA125 levels in 25 post-operation advanced ovarian cancer patients were retrospectively analyzed and com- pared with those in 20 control cases. Results: After 1 cycle of chemotherapy, CA125 levels had decreasing trend compared with control, but had no statistical significance. While after two cycles of chemotherapy, CA125 levels decreased more rapidly compared with those in control. Side effects in two groups were alike. Conclusion: CMNa combined with paclitaxel and car- boplaline has a stronger effect on the decrease of elevated CA125 levels than paclitaxel and carboplatin have in the treatment of post-operation advanced ovarian cancer, which indicates that CMNa has chemo-sensitizing effects on chemotherapy of paclitaxel and carboplatin.展开更多
