Aim:
To evaluate survival and toxicity in a cohort of patients treated with stereotactic body radiation therapy (SBRT) for unresectable intrahepatic malignancies.
Patients And Methods:
From 2007 to 2014, 23 patients with 34 lesions (three primary and 31 metastatic liver tumors) were treated with SBRT.
Results:
The median follow-up was 9 months (range=1-76) for all patients. Local control was reached in 27 out of 34 (79%) treated lesions, with 1 and 2 years rates of 93% and 73%, respectively. The progression-free survival at 1-year and 2-year was 50% and 25%, respectively. Median overall survival was 16 months (95% confidence interval=8-24 months), with 1-year and 2-year rates of 58% and 41%, respectively. Toxicity was very low consisting mainly of grade 1 and 2 events.
Conclusion:
SBRT provides good local control for both primary and metastatic liver lesions, with minimal toxicity.
