Accurate outcome prediction after neo-adjuvant radio-chemotherapy for rectal cancer based on a TCP-based early regression index

Abstract

BACKGROUND AND PURPOSE: was tested as a potential biomarker in predicting long-term disease-free survival. MATERIALS AND METHODS: (CONV_model and REGR_model respectively) were assessed and their discriminative power compared. RESULTS: was also the only variable significantly associated to OS (p = 0.01) and LRFS (p = 0.03). CONCLUSION: in treatment personalization: additional confirmation on independent cohorts is warranted.
