OBJECTIVES: To evaluate the efficacy and safety of a conformal Short Course Accelerated Radiation therapy (SHARON) for symptomatic palliation of locally advanced or metastatic cancers in older patients. MATERIALS AND METHODS: This is a pooled analysis on patients aged ≥80 years selected between subjects enrolled in 3 phase I-II studies on a short course palliative treatment of advanced or metastatic cancer. The primary endpoint was to evaluate the symptoms response rate produced by accelerated radiotherapy delivered in 4 total fractions in twice a day. Total dose ranged between 14 Gy and 20 Gy while dose/fraction between 3.5 and 5 Gy. RESULTS: A total of 48 patients were included in this analysis. Twenty-six patients (54.2%) had advanced primary or metastatic head and neck tumors, 11 (22.9%) locally advanced or metastatic thoracic cancers, 11 (22.9%) complicated bone metastases. The majority of patients presented pain (60.4%). With a median follow-up time of 5.5 months, no G4 acute and late toxicities were recorded. The overall palliative response rate was 91.7% with a median duration of palliation of 4 months.

Abstract

OBJECTIVES: To evaluate the efficacy and safety of a conformal Short Course Accelerated Radiation therapy (SHARON) for symptomatic palliation of locally advanced or metastatic cancers in older patients. MATERIALS AND METHODS: This is a pooled analysis on patients aged ≥80 years selected between subjects enrolled in 3 phase I-II studies on a short course palliative treatment of advanced or metastatic cancer. The primary endpoint was to evaluate the symptoms response rate produced by accelerated radiotherapy delivered in 4 total fractions in twice a day. Total dose ranged between 14 Gy and 20 Gy while dose/fraction between 3.5 and 5 Gy. RESULTS: A total of 48 patients were included in this analysis. Twenty-six patients (54.2%) had advanced primary or metastatic head and neck tumors, 11 (22.9%) locally advanced or metastatic thoracic cancers, 11 (22.9%) complicated bone metastases. The majority of patients presented pain (60.4%). With a median follow-up time of 5.5 months, no G4 acute and late toxicities were recorded. The overall palliative response rate was 91.7% with a median duration of palliation of 4 months.
