Bronchogenic carcinoma in the young population (40 years of age or less) is reported to present in an advanced stage and to have a virulent course. Between 1969 and 1979, 101 patients (65 men and 36 women) presented with cancer of the lung. Their mean age was 36.2 +/- 3.9 years (range 18 to 40 years). Eighty-seven percent had a history of cigarette smoking. Fifty percent of the patients had a strong familial history of malignancy of several organs. The interval between onset of symptoms and diagnosis was 4.01 +/- 3.48 months (3.56 +/- 3.34 for the surgically treated group and 4.16 +/- 3.53 for the nonoperated or unresectable group). Diagnosis was made at bronchoscopy in 32 patients, during thoracotomy in 30 patients, during nodal biopsy in 28 patients, and on cytologic examination of the sputum in 9 patients. The most common cell types were adenocarcinoma in 39 patients, squamous carcinoma in 29 patients, and oat cell carcinoma in 18 patients. Eighty-six patients (the majority) presented in stage III, whereas 9 were in stage I and 6 were in stage II. Twenty-seven patients (26.7 percent) underwent resection for cure, whereas 18 patients were inoperable at surgery. Eighteen of the surgical patients had adjuvant radiotherapy, and chemotherapy, immunotherapy, or both. The average length of survival for the nonresected patients was 7.12 +/- 5.9 months (range 1 to 36 months) and the actuarial survival was 1.5 percent at 36 months. The survival for the surgically managed patients was 56.1 +/- 52.6 months (range 3 to 168 months) or 48 percent at 36 months. At 46 to 168 months after treatment, the only survivors were 13 patients who were surgically managed. Stage III patients had longer survival after surgery (24.1 +/- 24.6 months to 7.09 +/- 5.90 months; range 3 to 74 months and 1 to 36 months, respectively). The survival at 5 years for patients with stage I disease was 78.8 percent, stage II disease 66.6 percent, and stage III disease, 3.6 percent. Early diagnosis and aggressive surgical management are necessary to improve the survival of patients with bronchogenic carcinoma under 40 years of age.
