Incidence rates have increased more rapidly in women than men and at a faster rate among women than other cell types. To investigate the importance of smoking and other risk factors, a case-control study of SCLC in women was conducted. A total of 98 women with primary SCLC and 204 healthy controls, identified by random-digit dialing and frequency matched for age, completed telephone interviews. Data collected include demographics, medical history, family cancer history, residence history, and lifetime smoking habits. Risk for small cell carcinoma in women is strongly associated with current use of cigarettes.
Risk increases steeply with pack-years of smoking and decreases with duration of smoking cessation.
After adjusting for age, education, and lifetime smoking history, medical history of physician-diagnosed respiratory disease including chronic bronchitis, emphysema, pneumonia, tuberculosis, asthma, and hay fever is not associated with a significant increase in lung cancer risk. Our results indicate that FucGM1 is a relevant ganglioside antigen in SCLC, and suggest that specific immunotherapy involving more than one ganglioside antigen in SCLC should at least include FucGM1 and GD3. TI - Serum LDL cholesterol concentration and lipoprotein electrophoresis pattern in patients with small cell lung cancer. AB - Epidemiological studies show that people with low level of total cholesterol have a greater risk of death due to cancer, predominantly lung cancer. The aim of our study was to evaluate serum level of LDL cholesterol and lipoprotein electrophoresis pattern in patients with small cell lung cancer and their dependence on clinical stage of the neoplasm.
