Overview

Cross-sectional study reveals frequent abdominal pain, anemia, and elevated inflammatory markers in colorectal cancer patients, highlighting opportunities for earlier referral and diagnosis.

Key Points

  • To identify the clinical symptom patterns and abnormal laboratory findings present in patients with colorectal cancer prior to definitive diagnosis.
  • Cross-sectional study conducted at the gastroenterology department of Rangpur Medical College, Rangpur, Bangladesh, between January 2019 and December 2023.
  • Evaluated prediagnostic clinical records, laboratory profiles, and imaging results for 1,150 patients with colonoscopy- and histopathologically proven colorectal carcinoma (73.47% male, 26.52% female).
  • The most common prediagnostic symptoms were abdominal pain (77.39%, n=890), altered bowel habits (46.95%, n=540), anemia/pallor (29.56%, n=340), weight loss (23.21%, n=267), and rectal bleeding (20.69%, n=238).
  • Common laboratory abnormalities included elevated C-reactive protein (65.56%, n=754), elevated erythrocyte sedimentation rate (51.22%, n=589), and decreased hemoglobin (47.04%, n=541).
  • Significant diagnostic delays occurred: 50.86% (n=585) presented between 6 months and 2 years after symptom onset, and 35% consulted three or more physicians before confirmation.
