Some patients cannot receive curative treatment and are treated with palliative irradiation. We aimed to identify prognostic factors for survival to facilitate treatment personalization for this group. Patients and Methods: Twelve patients treated with palliative radiotherapy for locally advanced sino-nasal cancer were retrospectively analyzed for survival. Ten characteristics were evaluated including age, gender, Karnofsky performance score (KPS), pre-radiotherapy hemoglobin, tumor site, lymph node involvement, histology, equivalent dose in 2 Gy-fractions, completion of radiotherapy and concurrent chemotherapy. Results: On univariate analysis, KPS ≥70 (p<0.001) and completion of radiotherapy (p<0.001) were significantly associated with better survival. Chemotherapy showed a trend (p=0.097). In the multivariate analysis, KPS ≥70 was significant (p=0.025), and completion of radiotherapy showed a trend (p=0.080). Conclusion: KPS is an independent predictor of survival for palliative irradiation of sino-nasal cancer. Patients require close monitoring and care for side effects, since completion of radiotherapy is important for survival. ER -
