One half of all cases of lung cancer occur in patients aged 65 years and older. Although adenocarcinoma is the predominant histologic subtype in the general population, squamous cell carcinoma has remained the most common type in the elderly. Although lung cancer tends to present at a less advanced stage with increasing age, the percentage of elderly patients undergoing treatment tends to decline despite the fact that they can tolerate the aggressive therapy that may enhance survival.
所有肺癌病例中有一半发生在65岁及以上的患者中。尽管腺癌是普通人群中主要的组织学亚型，但鳞状细胞癌在老年人中仍然是最常见的类型。虽然肺癌往往随着年龄增长在较晚阶段出现，但尽管老年患者能够耐受可能提高生存率的积极治疗，但接受治疗的老年患者比例却趋于下降。
