Sarcomas of the nose and paranasal sinuses are rare malignancies. Key
issues remain unresolved in the management of these tumors, particular
ly with regard to the role of radiotherapy. To help clarify these issu
es, 48 consecutive cases of nasal and paranasal sinus sarcomas treated
at the University of California, Los Angeles, between 1958 and 1988 w
ere retrospectively reviewed. Six of 16 patients managed initially wit
h surgery alone were cured. All had negative surgical margins and 5 of
the 6 had low-grade tumors. Of 5 patients with high-grade lesions tre
ated with surgery only, 1 was rendered free of disease. Twelve patient
s with positive surgical margins were treated with adjuvant radiothera
py; 5 were cured with this approach. Grade and surgical margin status
were found to be significantly related to outcome for sinonasal sarcom
a. There were 14 patients with rhabdomyosarcoma; 3 were cured with mod
em combined-modality therapy. Patients with positive surgical margins
should be treated with adjuvant radiotherapy. Surgical therapy is effe
ctive for low-grade lesions that are completely excised.
