小细胞未分化型肺癌约占原发性肺癌的20%,确诊时已有2/3患者广泛转移,病灶局限的仅占1/3,手术治疗不理想,对化疗则较其它细胞类型支气管癌敏感,而联合药物治疗又明显优于单一药物。本文为进一步筛选联合化疗方案,对63例小细胞未分化型肺癌做了临床观察,结果如下。 Small-cell undifferentiated lung cancer accounts for about 20% of primary lung cancer. Two-thirds of patients have extensive metastases at the time of diagnosis. Only 1/3 of the lesions are limited. Surgical treatment is not ideal, and chemotherapy is more common than other cell types. Sensitive, and combined drug treatment is significantly better than a single drug. In order to further screen combined chemotherapy regimens, 63 cases of undifferentiated small cell lung cancer were observed in this study. The results are as follows.
