Disparities in the Management of Patients With Stage I Small Cell Lung Carcinoma (SCLC): A Surveillance, Epidemiology and End Results (SEER) Analysis

Patients with stage I small cell lung carcinoma (SCLC) are candidates for surgery; however, not much is known regarding the utilization of surgical resection in the management of stage I SCLC and the factors that determine the patient's ability to receive surgery.The Surveillance, Epidemiology and End Results database was used to identify patients with stage I SCLC from 2007 to 2013. Continuous variables were compared with 1-way analysis of variance, and categorical variables were compared with χOf the 1902 patients with stage I SCLC, 427 (22.4%) underwent resection, 116 (6.1%) resection and radiation, 815 (42.8%) received radiation alone, and 544 (28.6%) did not undergo surgery or radiation. Median overall survival for patients with surgery plus radiation was 60+ months, followed by surgery alone at 50 months, radiation at 27 months, and no resection/radiation 16 months. Patients with ≥ 4 lymph nodes removed during surgery had better overall survival of 60+ months compared with patients with 4 lymph nodes removed (25 months); P .001. Multivariate analysis demonstrated that elderly patients, men, African American individuals, Medicaid recipients, and patients with left-sided tumors were less likely to undergo resection. However, county-level socioeconomic factors, such as level of poverty, education, unemployment, and median income did not affect the likelihood of undergoing resection.Fewer than one-third of all patients with stage I SCLC undergo resection despite better outcomes with resection. Elderly African American men with Medicaid insurance were less likely to receive resection.
