Abstract: This article reported 210 cases of carcinoma of the lung in women which was undergone surgical treatment and identified pathologically during 1, 1978 to 7, 1992. This was 20. 8% of the patients with lung cancer addmitted in the same period. The male to female incidence of lung cancer is 3. 8 ;1. Obvious clinical features was shown in women with lung cancer. 1. The age of carcinoma of the lung in women was younger than the age of men. The younger the patients with lung cancer, the more incidence the carcinoma of the lung in women. The incidence of the lung cancer in women was 43. 5% (10/23) of all patients with lung cancer in 30 years old or younger. 2. Adeoocarcinoma had higher incidence reaching to 44. 8% in women, then squamous carcinoma 22. 4%. In women the incidence of adenocarcinoma, carcinoid and other lower malignant tumor was higher, but there was none of the large cell carcinoma. 3. The resectable rate of the lung cancer in women was 77. 1 %, lower than in men, but pcotoperative mortality was 4. 3 %, higher than in men. 4. The 1-, 3-, 5-year's survival rate was respectively 74. 1 %, 39. 3%, 34. 4%. All of .them was higher than in men. The good prognosis was rebated to the recepator of estrogen in the adenocarcinoma cell. The data showed that sex may be an important factor suggesting prognosis.
