Correlation between MRI and biopsy investigations in diagnosis of colorectal cancer among patients presented with colorectal mass at St. Paul’s Hospital Millennium Medical College

Abstract

ABSTRACT Aims and objectives: To study correlation between MRI and biopsy investigations in diagnosis of colorectal cancer in patients presented with colorectal mass/rectal bleeding at St. Paul’s hospital Millennium Medical College from 2015 to 2019 GC. Materials and methods: This cross section retrospective study included all inpatients and outpatients at SPHMMC who presented with rectal bleeding or mass in the period of five years and with both MRI and biopsy investigations. Results: Total 162 patients 116 were included and 97.4 % presented with rectal bleeding 61.2% bleeding for six month, 2.6 % operable. Location 51.7% in mid rectum followed by lower rectum 36.2%. MRI T staging 12.0% were T1/T2 and 46.0% to T3 and 42.0% to T4. Of the study populations tumor histology; 91.4% were adenocarcinoma, 100% have had no staging used, and 55.2% could be operated. Conclusion MRI is useful and reliable modality for assessing preoperative staging and CRM involvement, permitting the physicians to stratify the patients and determine the optimal therapeutic planning for individual patients who need surgery also the patients who were at risk of recurrence. In St. Paul’s Hospital, a combination of high-resolution MRI with DWI before surgery is implemented for patients who were treated with preoperative CRT for locally advanced rectal cancer. Key words: Colorectal cancer, MRI and biopsy.
