Abstract
BACKGROUND: With the popularization of chest computed tomography (CT) early screening for lung cancer, the detection rate of lung cancer combined with multiple primary malignancies (MPM) in other organs has been increasing. In this paper, the incidence, pathological characteristics, diagnosis and treatment characteristics and prognosis were discussed and analyzed to provide research basis for improving the clinical diagnosis and treatment of this disease. METHODS: From September 2011 to September 2015, a total of 5,570 patients with lung cancer were treated in Jiangsu Cancer Hospital. The clinicopathological characteristics of 61 patients with lung cancer combined with MPM in other organs were retrospectively analyzed. RESULTS: The incidence rate of lung cancer combined with MPM in other organs in this group was 1.1%, of which 15 cases were synchronous MPM (SMPM), 46 cases were metachronous MPM (MMPM). Colorectal cancer, breast cancer and thyroid cancer accounted for the top three of lung cancer combined with MPM in other organs. The overall 5-year survival rate was 39.3% and 71.4% of patients died from metastasis or recurrence of lung cancer. Multivariate analysis showed that the clinical stage of lung cancer patients, the order of occurrence of lung cancer and other tumors, the treatment status of patients with other organ tumors and the presence of epidermal growth factor receptor (EGFR) gene mutation were important factors for the survival of the patients. CONCLUSIONS: The incidence rate of lung cancer combined with MPM in other organs is not uncommon. Lung cancer is the main cause of death compared with other organs tumors. Patients with advanced lung cancer, SMPM, lung cancer first, combined with tumor only receiving palliative treatment and without EGFR gene mutation had a poor prognosis.
