MR-PET for radiation oncology: the imaging perspective

Results: At analysis there were 50 patients in each arm. The severity of clinical proctitis was found to be similar in both groups of patients with 12.2 % of patients experiencing toxicity of grade 2 and above in digestible starch group versus 14.6% in the resistant starch group. Functional proctitis was similarly graded and it was found that 16.3 % patients in digestible starch group experienced toxicity against 10.2 % patients in the amylase resistant starch group. This difference was seen at 4th week and continued in the subsequent weeks till the end of radiation. Both groups had similar reported toxicity at 6 weeks post intervention. Both groups were also found to have similar incidence of grade 2 and above diarrhea. The non-digestible starch group was found to have 8% incidence as compared to 2% in the other group at the 5th and 6th week. The short chain fatty acid concentrations were found to be not significantly different in the groups at any point.
