Abstract: Background: Incidence of SCLC usually varies from 17-29% from biopsy/cytology specimens. In the SEER data, SCLC comprises of 18% of all primary lung cancer.
Recently it was observed that the incidence is increasing especially in women. This study was done to evaluate SCLC incidence in an urban hospital serving predominantly African-American population.
Method: A retrospective analysis of records of 100 patients diagnosed and treated for lung cancer at Provident Hospital since year 2000 was analyzed for the incidence of SCLC.
Result: Male-female ratio was 1.6:1. Sixty-three percent were seen in the age group of 51-70 yr. Eighty-three percent had non-small cell lung cancer (NSCLC) and seventeen percent had small cell lung cancer.
Among NSCLC adenocarcinoma was the common cancer (39%), followed by squamous cell (29%). Seventy percent of patients with SCLC were men and fifty-three percent of patients had extensive disease. Fourteen of the seventeen patients with SCLC were diagnosed and treated in year 2002-2003.
Conclusion: Like the SEER data this study also shows the increasing incidence of SCLC. However the increase is seen predominantly among men in African-American population. SCLC is almost always associated with smoking and with a poor prognosis.
This study stresses the importance of continued education against smoking to prevent the increasing incidence of this dismal disease.
Further follow up is needed to see if this increasing trend in SCLC in African-American population is continuing.

Ann's NOTE: Women and African American men, two of the communities targeted for advertising by the tobacco industry.
Is there any secret that advertising works? Tobacco advertising should be totally banned in our opinion. There is NO upside in health from smoking tobacco products even though the companies that sell it pretend it is so.
