Clinicopathologic characteristics of stage I lung adenocarcinoma in women

A total of 75 cases of surgically resected Stage I lung adenocarcinoma in women were analyzed. The patients were divided into three age groups: less than 50, between 50 and 70, and more than 70 years old. On the basis of the pathological T factor, 45 of 75 (60%) were T1 and 30 of 75 (40%) were T2 tumor. On the basis of pleural involvement, 47 of 75 (63%) cases revealed p0. On the basis of differentiation, all but two cases (97%) were well to moderately differentiated. On the basis of structure, papillary adenocarcinoma were 64 of 75 (85%). There was no difference among the three age groups in the pathological findings. Survival curves of each group indicated no statistically significant difference. We suggest that hormonal factors related to age do not affect the characteristics of lung cancer in women nor the survival of the patients.
