Prognostic factors for adult sarcomas of head and neck.

The optimal management of adult soft-tissue sarcomas is not clearly established. To assess prognostic factors and survival, the experience of 45 recent successive cases was reviewed. Data were collected from a retrospective database (1993-2005) and statistically analyzed. Rhabdomyosarcomas were excluded. The mean age was 50.1 years; there were 24 men and 21 women. The main histological subtypes were undifferentiated sarcoma (14) and angiosarcoma (10); 21 tumours were grade 3 (46%). The most frequent primary sites were neck muscles (15, 33%) and scalp (11, 24%). At presentation, 5 (20%) cases with lymph-node involvement and another 11 cases (24%) with distant metastasis were observed. The treatment was with curative intent in 33 cases (73%). This entailed surgery, with adjuvant radiotherapy in 15 cases and adjuvant chemotherapy in 5 cases. The 5-year overall survival was 52% (+/-8%). In univariate analysis, the poor prognostic factors were high grade, initial metastasis or lymph nodes, absence of surgery, and number of surgical procedures. In multivariate analysis, two factors remained significant: grade (P=0.006) and absence of surgery (P=0.005). After taking into account grade and metastasis at presentation, quality of surgery has prognostic value. The primary aim of a multidisciplinary approach to these tumours must favour complete resection.
