Prophylactic versus reactive feeding approach in patients undergoing adjuvant radiation therapy for oral cavity squamous cell carcinoma: A propensity score matched-pair analysis

BackgroundTo assess the efficacy of prophylactic versus reactive feeding strategy in oral cavity squamous cell carcinoma (OCSCC) patients receiving adjuvant radiation therapy (RT). MethodsThis was a post hoc analysis of patients of OCSCC enrolled in a randomized trial comparing three adjuvant strategies. In this trial, till 2010, a prophylactic feeding approach was followed for all patients. Since January 2011, a reactive feeding approach was followed. ResultsTwo hundred and sixty-eight in each cohort (total n = 526) were eligible for analysis after propensity score matching. At 6 weeks post-RT completion, the median weight loss in the prophylactic versus reactive cohort was 5 versus 3 kg, p = 0.002. At all other time points until 1 year, the median weight loss was lesser in reactive than in the prophylactic cohort. ConclusionsA reactive feeding tube approach should be preferred for OCSCC receiving adjuvant RT.
