Abstract
Subject headings
Close
- 5-Fluorouracil (5-FU)-based chemotherapy is the mainstay of adjuvant treatment for colorectal cancer (CRC). Few studies have explored Helicobacter pylori (H. pylori)-associated gastrointestinal symptoms in the diagnosis of CRC, and the association between H. pylori infection and gastrointestinal toxicity during adjuvant chemotherapy in CRC. Seventy-nine CRC patients were randomised in a prospective clinical trial to receive 5-FU and leucovorin administered as bolus injection (Mayo regimen) or continuous infusion (simplified de Gramont regimen). H. pylori antibodies were analysed at baseline, twice monthly during treatment and after treatment up to 12 months. Thirty-seven patients (47%) were H. pylori-seronegative at baseline. There was no significant association between baseline H. pylori seropositivity (n=42; 53%) and oro-gastrointestinal toxicity during chemotherapy. The median time from symptom onset of CRC to surgery was significantly longer in patients with H. pylori infection (median time, 6 vs. 5 months; P=0.012). Functional dyspeptic symptoms at presentation significantly delayed diagnosis (median time, 7.5 vs. 5 months; P=0.035), whereas anaemia, bowel symptoms, occlusion, blood in the stool, infection and hypolactasia did not. We conclude that there is no association between H. pylori status and gastrointestinal toxicity in CRC patients during chemotherapy. Dyspeptic symptoms and presence of H. pylori may delay the diagnosis of CRC. (www.controlled-trials.com/ISRCTN98405441).
