Avoidable delay in the management of carcinoma of the right colon.

A retrospective study of 89 consecutive patients with carcinoma of the right colon presenting in a district general hospital over a 5-year period is reported. Of the patients, 74% were anaemic at the time of diagnosis and 27% of these had anaemia or a low mean corpuscular volume (MCV) for a significant time (mean 177 days, range 76-496 days) before developing symptoms. All doctors should be more vigilant towards anaemia or low MCV as presymptomatic indicators of possible colonic disease. Appropriate investigation is required in order to detect disease at an earlier stage and therefore influence survival. Significant delay in the diagnosis of symptomatic disease occurs before referral to hospital (mean 61 days vs 36 days, P < 0.05). Treatment delay is similar whether patients are referred to surgeons or physicians. The preoperative duration of symptoms for emergency admissions was significantly shorter than for elective admissions (mean 50 days vs 119 days, P < 0.05). The 30-day mortality was significantly higher for emergency admissions (20.7% vs 3.3%, P < 0.05). Earlier diagnosis of symptomatic disease may not reduce the proportion of emergency admissions (33%) or improve survival. Many tumours are at an advanced pathological stage (39% node positive) by the time symptoms develop.
