本文通过74例原发性肺癌尸检分析表明:发病年龄26～94岁,平均66.5岁,男:女为5.2:1;好发部位为右上肺(33.8%);组织类型以腺癌最高(32.4%);鳞癌易经淋巴道转移,腺癌和未分化癌易经血道转移,肝脏最易受累,肾上腺和骨次之;死亡原因主要是肺癌广泛转移造成全身衰竭和肺部继发感染。 In this paper, autopsy analysis of 74 cases of primary lung cancer showed that the age of onset was 26 to 94 years old with an average of 66.5 years, male to female was 5.2:1; the predilection site was right upper lung (33.8%); the tissue type was highest in adenocarcinoma (32.4) %); squamous cell carcinoma is easy to be lymphatic metastasis, adenocarcinoma and undifferentiated carcinoma are easy to metastasize by blood, liver is most susceptible, adrenal and bone are the second, and death is caused by extensive metastasis of lung cancer causing systemic failure and secondary pulmonary infection.
