Introducción.- Los Sarcomas de Partes Blandas, son considerados un grupo de tumores poco frecuentes, pues su incidencia supone menos del 1% de todas las neoplasias, agrupadas en diferentes subtipos, ambos criterios (baja incidencia y diversidad de tipos) ayudan a explicar las dificultades para investigar y desarrollar con rapidez modelos terapéuticos eficaces.

Abstract: | |
Soft tissue sarcomas appear at any age, although more frequent after the fourth decade of life. There is a realationship between some histological types of presentation. The term Soft Tissue sarcoma refers to a variety of rare tumors that originate from structures that connect, support or surround other organs and tissues commonly called soft tissue or part, so they area grouped as heterogeneous tumors tha show common histological features that are due to its histogenesis . In this paper we describe the clinical characteristics such as age of onset, sex, histological type, stage of disease and anatomical location. Material and Methods.- 53 patients with soft tissue sarcomas of head and neck from the National Institute of Oncology and Radiobiology were analyzed, between 1975 and 2005. Results.- The age of highest incidence was childhood with great foundness for the orbital region, within the hitological sbtype, the most frequent was Rhabdomyosarcoma. The most used tratment was surgery followed by radiotherapy, with poor response to treatment for a complete remission of 18.9% and 81.9% partial, where the most common clinical stage at diagnosis was III for 44.7%, followed by stage IV for a minimun 30.2 % with predominance in males compared to females. Conclusions.- Soft tissue sarcomas of the head and neck occur in all age groups, located in any region of the head and neck, but more often in orbit, mouth middle ear and nasopharynx.
