Patient's and doctor's delay in carcinoma of the colon and rectum.
Despite sophisticated diagnostic equipment and modern surgical therapy, the prognosis for patients with colorectal carcinoma has not improved during the last few decades. One of the factors, possibly contributing to the prognosis, is the time between the patient's visit to the doctor and the final therapy. In order to estimate patients' and doctors' delay and to investigate the factors which may influence the time of delay, a prospective study was designed including 50 patients with carcinoma of the rectum or the sigmoid colon and 50 patients with colonic carcinoma above this level. All patients were interviewed by a doctor using a standard questionnaire, and initial symptoms, duration of symptoms, and type of clinical examination leading to diagnosis were recorded. The results show that 16% of the patients in the recto/sigmoid group suffered from patient's delay as opposed to 20% in the group of patients with carcinoma above 25 cm from the anal verge. Doctor's delay was found in 27% of all cases, being evenly distributed in the two groups. The reason for doctor's delay was usually the doctor's neglecting to perform rectosigmoidoscopy or rectal palpation, and in some cases a false-negative X-ray. No significant correlation was found between tumor stage and doctor's or patient's delay.
