BACKGROUND: The relationship between the location of the primary tumor and survival of adenosquamous carcinoma (ASC) remains poorly understood. This study aimed to evaluate the impact of primary tumor location on the survival outcome of patients with ASC.
METHODS: Patients with ASC were extracted from the Surveillance, Epidemiology, and End Results (SEER) database with ≥ 150 cases per tumor location. The Kaplan-Meier method was used to generate survival curves and differences among them were compared using the log-rank test. On the other hand, Cox proportional hazards models were used to evaluate factors that had independent predictive effects on cancer-specific survival (CSS).
RESULTS: A total of 14,829 eligible patients with ASC were included in this study. Lung and bronchus ASC accounted for 51.1%, followed by the cervix uteri (17.0%), corpus uteri (13.9%), pancreas (4.9%), esophagus (3.1%), gallbladder (2.5%), stomach (2.2%), colon and rectum (2.0%), head and neck (1.8%), and breast ASC (1.3%). The 5-year CSS of breast, cervix uteri, colon and rectum, corpus uteri, esophagus, gallbladder, head and neck, lung and bronchus, pancreas, and stomach ASC was 76.9%, 66.0%, 34.8%, 72.9%, 12.0%, 10.8%, 45.0%, 24.7%, 4.3%, and 17.3%, respectively. COX analysis demonstrated that the primary tumor location was an independent prognostic factor for CSS. Besides, the breast, uterine corpus, and cervix as well as head and neck ASC were significantly associated with better prognosis, while pancreas and gallbladder ASC were significantly associated with poor CSS; stomach and colorectal were roughly the same as ASC prognosis.
CONCLUSION: Our study showed that the CSS of patients with ASC depends on the location of the primary tumor. Besides, tumor location is an important factor that should guide the use of chemotherapy and radiation.
