Clinicopathologic features of colorectal carcinoma: features predicting higher T-stage and nodal metastasis.

Objectives: A rising frequency of colorectal carcinoma has been noted in recent years in Pakistan. In the present study, we aimed to evaluate clinicopathologic features of colorectal carcinoma in our population so that protocols could be developed to stratify patients that may require further biomarker/molecular testing. Furthermore, histological features which predict higher T and N stage were also evaluated.
