What proportion of spine met failures following involved field only SBRT would have been covered by a standard extended field covering adjacent uninvolved spine segments?
What proportion of patients who have neurocognitive failure after radiation for brain metastases recover by 6 months?
In EORTC 1414, what proportion of patients receive radiation for prostate cancer had a PSA nadir <0.1 with 6 months of LHRH antagonist versus agonist?
Answers
Two-thirds. In this phase 2 trial, the rate of local failure at 12 months was significantly lower with the extended field approach (3.8% v 13.5%).
38% in this meta-analysis of 3 clinical trials. Patients treated with SRS were more than twice as likely to recover from NCF.
60% v 52%, which was not statistically significant. PFS at 2 years was also similar. | QuadShot News
