Soft tissue sarcomas in children are a heterogeneous group of malignant diseases. Among these, tumors localized in the head and neck region are especially difficult to treat. While multidisciplinary care has dramatically improved the prognosis of sarcoma patients, their treatment remains uncertain because of demand on radical surgical resection of the tumor. Achieving cure without deforming or mutilating the child remains the primary goal of treatment. This study is the multicenter (nationwide, 11 Polish centers) retrospective analysis of the treatment results in children having soft tissue sarcoma in the head and neck region during the previous decade (from 1991 to 2001). Late effects of the treatment are documented in long-term survivals. Eighty-five children from 1 to 212 months of age were included. Different multimodal treatment protocols were utilized (CWS-91, SIOP-MMT-91, and CWS-96). The median observation time was 25 months. Data on long-term effects were collected in 34 long-term survivals. Complete remission was achieved in 68 (80%) patients. Primary treatment failure occurred in 13 (15.3%) patients, all of whom succumbed in disease progression. Relapse occurred in 21 (30.9%) patients primarily achieving complete remission. Second primary neoplasm occurred in 3 children. The estimated 5-year event-free survival and the 5-year total survival rates for the whole group are 0.38 and 0.55, respectively. The main late effect documented in long-term survivals were cosmetic defects in 12 (35.3%) and visual field deficit or blindness in 8 (26.5%). Despite substantial improvement of the prognosis of pediatric soft tissue sarcomas, the multimodal treatment of head and neck region tumors remains controversial. Improved long-term outcome and focusing on psychosocial difficulties raise the important and difficult problem of functional results and cosmesis. Tumors localized in the orbit carry an excellent prognosis. However, the main late sequela is vision impairment and cosmetic defect due to the therapy given many years earlier. Two other tumor localizations--the parameningeal and nonparameningeal ones--still have bad prognosis. The observations made in this study confirm that main prognostic factors are the size of the primary tumor and the tumor stage. The worst prognosis remains invasive tumor (T2-stage) with a size over 5 cm. Individually adjusted multimodal therapy, which imperatively needs to be radical, though not mutilating, might minimize the late effects. Psychosocial problems in long-term survivors need to be focused on at the national level and better support must be provided in the future, involving a team of different medical and paramedical profiles.
