A new study has found that patients who have colorectal cancer (CRC) diagnosed following a colonoscopy screening are more likely to survive longer.
Compared to those who wait for symptoms until the test is conducted, patients who are routinely screened have a much better prognosis.
The researchers looked at 312 patients in ten gastroenterology practices in Germany and found 60 patients who were diagnosed during a screening colonoscopy and 252 who had shown symptoms.
Published in American Society for Gastrointestinal Endoscopy (ASGE), the study found that those who had cancer detected during screening colonoscopy lived 20.2 months longer, on average.
More than half of the patients (55 per cent) who demonstrated symptoms before the test survived for at least the ten-year study period, while more than three-quarters (77 per cent) of screening colonoscopy patients achieved the same.
According to the lead author Dr Kilian Friedrich, the study shows that screening colonoscopy can contribute to reduced mortality from colorectal cancer by catching tumours at earlier and more treatable stages.
