Stage I adenocarcinomas of the lung: survival of females and males.
Seventy-two cases of Stage I lung adenocarcinomas in females were analyzed and compared with 84 cases in males, all of which were surgically resected at the National Kyushu Cancer Center Hospital in Japan. The females with Stage I adenocarcinomas had a tendency, that was not significant, towards a longer survival than the male patients. When subdivided by age into less than 50, between 50 and 70, and more than 70 years-old, the female patients had a tendency, that was not significant, towards a longer survival in each group. In each age group, the ratio of smokers to non-smokers was higher in the males. The female group of ages 50 to 70 had the best 5-year survival rate. By multiregression analysis, age was found to be the most important factor for improved survival. The results indicate that a hormonal factor in Stage I lung adenocarcinoma does not influence survival.
