Delay in the diagnosis and prognosis of carcinoma of the right colon

Abstract

Of 152 consecutive patients with carcinoma of the right colon, 61 (40 per cent) suffered delays in treatment of more than 12 weeks from the onset of symptoms, with a mean delay of 48 weeks. The most common error was failure to initiate or complete the investigation of iron-deficiency anaemia (33 patients). False-negative barium enema investigations occurred in 16 cases. Patients with delays in diagnosis had survival rates not significantly different from those who presented early. Thirty-one patients with anaemia and no abdominal symptoms had a significantly higher survival rate than 30 presenting with abdominal symptoms, despite delays in treatment (P <0·02). Greater vigilance is required in the investigation of patients presenting with iron-deficiency anaemia.
