RESUMO
Soft tissue sarcomas (STS) constitute a rare heterogeneous group of tumours that include a wide variety of histological subtypes, which require a multidisciplinary and, frequently specialized and complex management. Despite advances in our understanding of the pathophysiology of the disease, there are no consensus multidisciplinary recommendations about its diagnosis and treatment in our country. The objective of these guidelines is to provide practical therapeutic recommendations that may contribute to improve the therapeutic results of this disease in our environment. With this purpose, the Spanish Group for Research in Sarcomas (GEIS) held a meeting with a multidisciplinary group of experts for the study and management of sarcomas. The results of this meeting are compiled in this document, in which recommendations on diagnosis, treatment and monitoring of soft tissue sarcomas are included. In summary, these guidelines aim to facilitate the identification and management of STS for clinical practice in Spain.
