Task: Answer Verification
Input (English): Question: Does co-morbidity index predict for mortality after stereotactic body radiotherapy for medically inoperable early-stage non-small cell lung cancer?
Answer: The number and seriousness of co-morbidities predict overall survival in medically inoperable early-stage NSCLC treated with SBRT. Because the determination of medical operability is frequently based on both objective measures and subjective clinical judgment, it is recommended that co-morbidity be formally indexed in all studies examining the outcomes of SBRT.
Output (English): yes
