1978年元月至1990年12月我院共收治小细胞未分化肺癌508例,对其作较长期生存率的统计及预后因素分析。结果生存1年171例(33.7％),2年60例(11.8％),3年43例(9.6％)。影响小细胞未分化肺癌较长期生存的一般因素为病人的性别、病变范围、治疗方式及首次症状至治疗开始的间隔时间等。但根据本文已死亡的465例死因分析,90％以上死于生命重要器官的广泛转移,这是影响小细胞未分化肺癌预后的最主要因素。
From January 1978 to December 1990, a total of 508 small-cell undifferentiated lung cancer patients were treated in our hospital. Statistical analysis and prognostic factors of long-term survival were analyzed. Results 171 cases (33.7%) survived 1 year, 60 cases (11.8%) 2 years, and 43 cases (9.6%) 3 years. The general factors affecting the long-term survival of small cell undifferentiated lung cancer are the patient’s gender, extent of disease, treatment methods, and the interval between the first symptom and the start of treatment. However, according to the analysis of 465 causes of death that have been reported in this paper, more than 90% of them died of widespread metastasis in vital organs. This is the most important factor affecting the prognosis of undifferentiated small cell lung cancer.
