Trial Outcomes & Findings for Stereotactic Body Radiation Therapy in Treating Patients With Liver Cancer That Cannot Be Removed by Surgery (NCT NCT01899261)

Stereotactic Body Radiation Therapy in Treating Patients With Liver Cancer That Cannot Be Removed by Surgery

The percentage of patients who have severe treatment-related toxicity will be computed, along with exact 95% confidence intervals. Severe toxicity will be defined as grade 4 or 5 hepatic toxicity, thrombocytopenia, or gastrointestinal toxicity, graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0

Cancer Specific Survival (CSS) was assessed in patients who were diagnosed with HCC and treated with liver SBRT as the percentage of patients with Cause-Specific Death from HCC. Patients alive at the end of the follow-up period were censored. Competing risk analysis was performed.

Overall Survival, estimated using the Kaplan-Meier method, reflected the percentage of patients who were were diagnosed with HCC and started SBRT treatment and were still alive at the conclusion of the study.

Time to Local progression (TTLP) of treated lesions in HCC patients after liver SBRT treatment was evaluated using Response Evaluation Criteria In Solid Tumors Criteria (RECIST). For patients who died from the study disease without progression of the radiated lesion, time to local progression was censored at the date of death. For patients not known to have died as of the data cut-off date, and who did not have locally progressive disease, time to local progression was censored at the last progression-free disease assessment.
