| Abstract | Background: There is no definite and detailed treatment guideline for advanced thymic tumors which means the presence of lymph nodes and other organs metastasis, and clinical guidelines recommend chemotherapy-based multidisciplinary treatment. Previous studies found that surgery played a beneficial effect on advanced thymic tumors, but because of few cases with advanced thymic tumors and incomplete studies, the role of surgery is still unknown. Therefore, this paper aims to systematically analyze the role of surgery in advanced thymic tumors based on the Surveillance, Epidemiology, and End Results (SEER) database with a sufficient number of cases. The significance of this study is to clarify the prognostic value of surgery in advanced thymic tumors. Method: The total number of 979 patients with advanced thymoma or advanced thymic carcinoma were collected from the Surveillance, Epidemiology, and End Results (SEER) database. The propensity score matching was performed to eliminate confounding factors, and Cox regression analyses were executed to assess prognosis. Results: This study put all patients into four groups according to pathology and surgery or not: Thymoma (Surgery), Thymoma (No Surgery), Thymic carcinoma (Surgery), and Thymic carcinoma (No Surgery). Before and after propensity score matching, disease-specific survival was significantly different between advanced thymoma(surgery) and advanced thymoma (no surgery) (p< 0.001 and p<0.001); Similarly, disease-specific survival was significantly different between advanced thymic carcinoma(surgery) and advanced thymic carcinoma (no surgery) (p< 0.001 and p=0.003). The no total resection, distant metastasis, and thymic carcinoma were all unfavorable prognostic factors. Conclusions: This study proved that whether in advanced thymoma or advanced thymic carcinoma, surgery played a positive role which significantly improved survival time. Meanwhile, the total resection of the primary site was better. This study would also provide a reference for the clinical treatment of advanced thymic tumors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
