EP.TH.63Predictive significance of tumour size in patients undergoing curative surgery for colorectal cancers: Retrospective cohort study

Abstract Aims Evaluating predictive significance of tumour size in patients undergoing curative colorectal cancer surgery. Methods Patients surgery (77.6% Laparoscopic) for by a single surgeon between January 2013 and 2020 inclusive. Linear/binary logistic regression analyses were modelled to assess whether colonic or rectal could predict R0 resection, specimen length, length >120mm, number harvested lymph nodes, >12 positive lymphocytic infiltration, venous invasion, overall survival. Results Total 192 (124 colon 68 cancers) eligible. In patients, was independent predictor the nodes (P < 0.001), = infiltration 0.009). It did not resection 0.563), 0.111), >120mm 0.186), 0.145), invasion 0.103), 5-year survival 0.543). Independent cancers 0.001). 0.108), 0.774), 0.405), 0.069), 0.912), 0.105), 0.413). Conclusions Current study results suggest alone may have significant value terms oncological outcomes rectum.
