AbstractThe National Advisory Committee on Health and Disability invited a working party to make recommendations on population screening for colorectal cancer in New Zealand. Recent results from randomised controlled trials of screening with guaiac faecal occult blood tests have provided evidence that population screening could reduce mortality from colorectal cancer. However, given the modest potential level of benefit, the considerable commitment of health sector resources, and the small but real potential for harm, the working party does not recommend population screening for colorectal cancer with faecal occult blood tests in New Zealand. The working party does nto recommend pilot colorectal cancer screening programmes in New Zealand because pilot programmes cannot address the issues of concern: the modest potential benefit and the small, but real, potential for harm. The working party does not recommend faecal occult blood testing as a screening test for colorectal cancer in average-risk individuals outside a population screening programme. Those requesting screening by faecal occult blood test should be given information about the potential risks and benefits. Follow-up bowel investigations in the public health system cannot be guaranteed without an increased allocation of resources. As there is yet no evidence from randomised controlled trials that screening with flexible sigmoidoscopy, colonoscopy or double-contrast barium enema produces a reduction in colorectal cancer mortality, the working party does not recommend population screening with these modalities. Wider consultation and further consideration should be undertaken to develop appropriate advice on surveillance recommendations for groups identified to be at increased risk of colorectal cancer. These decisions should be reviewed as evidence of benefit from new types of faecal occult blood test and other screening modalities becomes available. The working party recognises that colorectal cancer is an important cause of morbidity and mortality and recommends that New Zealand participate in international research in this area.
