Lu T, et al. - Researchers analyzed the changes in the incidence, treatment, and survival of lung cancer from 1973 to 2015 by using clinical and epidemiological data of patients with lung cancer from the Surveillance, Epidemiology, and End Results (SEER) database. They used Joinpoint regression models. Findings revealed an initial rise followed by a gradual decline in the incidence of lung cancer in the past four decades. Males vs females and black patients vs other racial groups had a higher incidence rate. Since 1985, adenocarcinoma was reported as the most prevalent histopathological type. Data revealed a nearly 25% surgical rate for lung cancer. A fluctuant reduction was reported for surgical rate, while the chemotherapy rate was in upward trend. Although increased 5-year relative survival rate was observed over the years, it was still low.
