Early diagnosis in colorectal cancer. Still no benefit?

Time to diagnosis from first symptoms has been assessed in 332 patients with colorectal cancer treated by the three general surgeons in Trafford Health Authority. When compared with other series, delay to diagnosis has been shortened, particular general practitioner and hospital delay. Fewer patients presented as emergencies and a greater proportion of patients had early-stage disease. There was no significant difference in delay times between Dukes' stage B and C patients but there was a significant difference in survival at 2 years between these two stages. Delay times for patients with risk factors, family histories or diverticular disease were not significantly different from times in patients without these factors.
