Bronchogenic carcinoma in young persons

Lung cancer in patients younger than 40 years of age

The records of 52 patients younger than 40 years of age who had bronchogenic carcinoma diagnosed between 1965 and 1985 were reviewed. The preponderance of adenocarcinoma (54%), the lower male-female ratio in this age group compared with patients age 40 or older (2:1), the importance of cigarette smoking as a causative factor (80% of patients), the long mean duration of symptoms (5 months), and the high incidence of advanced stage at diagnosis (77% Stages III and IV) in these patients are findings similar to those reported in other published series. There was no significant difference in resectability (23% versus 19%), median survival length (5.3 months versus 6.9 months), median survival length of patients who had surgical resection (10.5 months versus 10.8 months), and 5-year survival rate (11.5% versus 6.3%) in these patients compared with a randomly selected group of 260 patients with lung cancer who were age 40 or older.

Lung cancer in the young

A long-term retrospective study was carried out on 1,514 cases of lung cancer to assess whether the disease presents substantial differences in young as compared to older patients. Clinical, epidemiologic, surgical, and survival data were evaluated in all cases. A young group under 45 years of age was studied separately and compared with the remaining older patients. In contrast with the literature, our results showed no percentage increase or variation in the male/female ratio of lung cancer in the young group. No significant difference was found regarding clinical picture, operability, histotype, and prognosis.

Lung cancer in younger patients

Carcinoma of the lung is rare in younger patients, but occasional reports of this condition have appeared in the literature. This article reviews the clinical and pathological patterns of bronchogenic carcinoma in 96 patients, 40 years old or younger seen at UCLA (University of California, Los Angeles) Hospital between 1956 and 1976. This review confirms the finding in other reports of a higher proportion of women among younger patients with lung cancer as well as a relatively low incidence of squamous cell carcinoma. Using comparative data from the UCLA and California tumor registries, we could find no significant difference in survival of the younger patients when compared with the general population of patients with lung cancer.
