回顾恶性肿瘤化疗的发展史,直至今天,化疗的疗效有了突破性的提高。本文对恶性肿瘤化疗的疗效进展,并结合本院临床观察的结果,作一综述。一、化学药物在治疗恶性肿瘤过程中的地位和作用手术和放射治疗,可使许多早、中期癌瘤病人得到治愈。然而,在诊断时不少患者就已存在着微小的转移灶,这是癌治疗失败的主要原因。近来Devita指出〔1〕:1955年以前癌的相对生存率的提高,主要是由于外科治疗的进展。1955～1965年期间,癌的相对生存率的提高是由于放射治疗及外科手术治疗的进步;但是在1965年
Reviewing the history of the development of chemotherapy for malignant tumors, to this day, there has been a breakthrough in the efficacy of chemotherapy. This article reviews the progress of the efficacy of chemotherapy for malignant tumors, combined with the results of clinical observation in this hospital. First, the status and role of chemical drugs in the treatment of malignant tumors Surgery and radiation therapy, can make many early and intermediate cancer patients have been cured. However, at the time of diagnosis, many patients already had tiny metastases, which is the main reason for cancer treatment failure. Devita pointed out recently that 〔1〕: The relative survival rate of cancer before 1955 was mainly due to the progress of surgical treatment. Between 1955 and 1965, the increase in the relative survival rate of cancer was due to advances in radiation therapy and surgical treatment; but in 1965
