Objective: To investigate the clinical characteristics and the prognostic outcomes of patients with gynaecological multiple primary malignant neoplasms (MPMN). Materials and methods: For a period of ten years, from January 2008 to December 2018, patients with gynaecological MPMN were enrolled for this study. The clinical characteristics and survival outcomes were collected and analyzed. Results: A total of 126 patients with gynaecological MPMN were included, comprising 15 synchronous MPMN and 111 metachronous MPMN. The average age of the patients with gynaecological MPMN was 57.6 \pm 10.8 years, and the probability of overall survival (OS) at 1, 2, 3, and 5 years was 88.6%, 82.6%, 76.9% and 68.7%, respectively. The OS of patients with gynaecological cancer as the first neoplasm was worse than those with non-gynaecological cancer as the first neoplasm (HR: 2.2, P = 0.049); the OS of patients accompanied by breast cancer was better than those accompanied by other cancers (HR: 0.346, P = 0.033). Univariate regression analysis showed that “age”, “FIGO stage” and “gynaecological cancer as the first neoplasm” were the factors for poor survival; “Accompanied by breast cancer” and “surgery for first or second neoplasm” were the factors for favourable survival. Conclusions: “Gynaecological cancer as the first neoplasm” is a factor for poor survival in patients with gynaecological MPMN, and “FIGO stage” is the independent risk factor (HR: 2.339, P = 0.001). “Accompanied by breast cancer” and “surgery for the neoplasm” are factors for favourable survival. Mostly, “surgery for the second neoplasm” was the independent protective factor (HR: 0.212, P = 0.005) for gynaecological MPMN.
