In order to define the characteristics of lung cancer in the elderly, 260 patients with lung cancer were retrospectively analyzed according to their age group ; group A=¾ 49 years (n=19), group B=50-69 years (n=152), and group C== 70 years (n=89).
The ratio of male to female increased with age from 1.4 (group A), 3.9 (group B) to 7.1 (groupC).
In males, the percentage of squamous cell carcinoma increased from 18% in group A, 30% in group B to 54% in group C. Conversely, in females adenocarcinoma was constantly high for all groups (100%, 71%, 91%). There was no significant difference in the distribution of the clinical stage of the disease among the three groups.
The percentage of patients undergoing surgery was lowest for group C with 15% compared to the two other groups with 32% and 28%, respectively.
Conversely, the percentage of patients receiving only the best supportive care was highest for group C with 24% (0% in group A, 10% in group B).
The prognosis for the patients in group C was significantly poorer than for the other groups ; median survival time was 12.5,10.0 and 7.0 months, with a 3-year survival rate (%) of 7.8,19.4 and 6.3% in groups A, B, and C, respectively.
Male and squamous cell type were characteristic of lung cancer in the elderly, apparently supporting the idea that cigarette smoking plays a role in lung carcinogenesis, and the necessity of early establishment of an optimal therapeutic strategy for lung cancer in the elderly was indicated.
