Popis: Objective: We analyzed the clinical features and prognosis of advanced intra- and extra-pulmonary neuroendocrine carcinomas (NECs) in order to provide further guidance for the clinical treatment of small-cell lung cancer, which is a type of advanced intrapulmonary NECs. Methods: The clinical data and survival of 123 patients with advanced intra- and extra-pulmonary NECs in the Fujian Medical University Union Hospital, Fujian Province, China, between January 2013 to November 2019 were collected. We retrospectively analyzed the corresponding clinical diagnosis and treatment, and explored the relevant factors affecting the survival prognosis of patients with intra- and extra-pulmonary NECs. Results: The data of 123 patients were collected. There were 90 cases of intra-pulmonary NECS (including 81 cases of small-cell lung cancer, SCLC), 25 cases of extra-pulmonary NECs involving in the gastrointestinal tract, and 8 cases of extra-pulmonary NECs in other regions. The median overall survival (OS) of intra-pulmonary NECs was 13.53 months, of which the median OS of SCLC was 12.97 months, and the median OS of other intra-pulmonary NECs was 27.07 months. The median OS of extra-pulmonary NECs in the gastrointestinal tract was 9.42 months, and the OS of extra-pulmonary NECs in the other regions was 8.69 months. The median OS of intra-pulmonary NECs was significantly longer than that of the extra-pulmonary NECs in the gastrointestinal tract and in the other regions (P < 0.05). Multivariate analysis showed that age, liver metastasis, number of cycles of first-line chemotherapy, and chest radiotherapy were risk factors affecting OS in patients with NECs (P < 0.05). Conclusions: The survival of intra-pulmonary NECs was significantly longer than that of extra-pulmonary NECs of the gastrointestinal tract and in other regions. However, patients with advanced intra- and extra-pulmonary NECs who were older and had liver metastases had a poorer prognosis. Multi-disciplinary treatments such as multi-cycle chemotherapy and combination of chemotherapy and radiotherapy should play an important role in prolonging the survival of NECs.
