A three-month follow-up PET/CT scan is very helpful for detecting the recurrence of oropharyngeal cancer and predicting the overall survival of patients treated with radiation therapy, according to a study presented at the recent American Society for Radiation Oncology (ASTRO) Multidisciplinary Head and Neck Cancer Symposium in Scottsdale, AZ.
Researchers from H. Lee Moffitt Cancer Center in Tampa, FL, found that the combination of imaging and a physical exam three months after radiation treatment identified 92% of cancer recurrences at the original site of the tumor. It also detected tumor spread, as well as 71% of distant cancer growth. The early three-month evaluation also contributed to a three-year overall patient survival rate of 91%.
