Delay of diagnosis and treatment of colorectal cancer--a population-based Danish study.

摘要

BACKGROUND: Recently, the authors have shown a doubled risk of having an advanced rectal cancer (RC) (Dukes' stage C or D) at the time of treatment, if the interval between onset of symptoms and start of treatment (treatment delay) was >60 days [Korsgaard M, Pedersen L, Sorensen HT, Laurberg S. Treatment delay is associated with advanced stage of rectal cancer but not of colon cancer. Cancer Detect Prev 2006;30(4):341-6]. The authors examined the treatment delay for colorectal cancer (CRC), as influenced by the patients, the general practitioners (G.P.), and the hospitals. METHOD: Population-based prospective observational study based on 743 Danish CRC-patients. Treatment delay was determined through questionnaire interviews. We examined the patient delay, the G.P. delay, and the hospital delay, and thereby the frequency of patients for whom the Danish fast-track recommendations of a maximum of 14 days to diagnose CRC, and 14 days from the diagnosis to start the of treatment, were met. Colon cancer (CC) and RC-patients were analyzed separately. RESULTS: Patient delay, in particular, was long, and longest for RC-patients (median 44 days vs.18 days). Median G.P. delay was short, but 25% of the CC-patients had a G.P. delay of 59 days or more, and 25% of the RC-patients had a G.P. delay of 53 days or more. The fast-track recommendations were poorly met; 53% of the CC-patients and 39% of the RC-patients waited >14 days after referral for the diagnosis. 29% of the CC-patients, and 53% of the RC-patients waited >14 days before the start of treatment. CONCLUSION: The total delay was too long, and can be shortened by optimizing all delay intervals.
