RESUMEN
Soft tissue sarcoma (STS) is a highly heterogeneous group of malignant tumors originating from mesenchymal tissues. The most common sites of STS are limbs (45%), viscera (21%) and retroperitoneum (17%). The incidence of head and neck soft tissue sarcomas (HNSTS) is the lowest (5%) compared with other areas of the body. Due to numerous functional organs and delicate and complex anatomical structures of the head and neck, it is often difficult to perform radical surgical treatment. Therefore, radiotherapy plays an important role in the treatment of HNSTS. Due to its low incidence, radiotherapy for HNSTS has been rarely studied and captivated little attention. In this article, the present situation and clinical evidence of radiotherapy for HNSTS were summarized, aiming to provide reference for clinical practice.
RESUMEN
Objective:To construct an index system for evaluating the development of research-oriented disciplines in medical institutions, and to provide a basis for guiding the superior disciplines towards international high-level disciplines.Methods:Through literature research and expert discussions, the basic framework of the research-oriented disciplines development evaluation system was established. The final version of the index system was determined using the Delphi method and expert interviews, and the weights of each index were established using the hierarchical analysis method.Results:After consultation, the framework of 5 first-class indexes, 16 second-class indexes, and 51 third-class indexes was finally constructed for the evaluation system of research-oriented discipline development, and the weights of indexes at different classes were calculated. The high-frequency terms " research mechanism construction" , " research team construction" and " representative research results" extracted from the expert interviews echoed the results of the weighting calculation.Conclusions:The evaluation system for research-oriented disciplines constructed in this study is relatively reasonable, scientific, reliable, and operable. The construction of the index system adapts to the characteristics of the development of research-oriented disciplines, with guiding significance for enhancing the development of research-oriented disciplines.
