[Life expectancy of lung cancer patients registered at the Leningrad City Oncological Dispensary in 1968].

Out of 1,240 lung cancer patients, a five-year survival was registered in 5.2% of cases (0.5% of unoperated patients, 34.3% of radically-operated among those who underwent surgery and 39.5% of patients discharged from hospital after operation). No relationship between the sex and age unoperated patients and prognosis was established. Among those radically-operated, 34.8% of young all 28% of aged patients survived for five years. Resectability should be considered the only reliable criterion of evaluation of diagnosis and treatment of lung cancer.
