Abstract
CONTEXT: Palliative radiotherapy aims at symptom alleviation and improvement of quality of life. It may be effective in conferring a reasonable quantum of local control, as well as possibly prolonging survival on the short term. However, there can be rare instances where long-term survival, or even cure, results from palliative radiotherapy, which mostly uses sub-therapeutic doses. AIM: To categorize and characterize the patients with long-term survival and/or cure after palliative radiotherapy. MATERIALS AND METHODS: This study is a retrospective analysis of hospital records of patients treated with palliative radiotherapy from 2001 to 2006 at the Regional Cancer Centre, Shimla. RESULTS: Of the analyzed 963 patients who received palliative radiotherapy, 2.4% (n = 23) survived at least 5 years, with a large majority of these surviving patients (73.9%, n = 17) being free of disease. CONCLUSIONS: In addition to providing valuable symptom relief, palliative radiotherapy utilizing sub-therapeutic doses may, in a small proportion of patients, bestow long-term survival, and possibly cure. Rationally, such a favorable, but rare outcome cannot be expected with supportive care alone.
