To assess the involvement of family physicians in the continuing care of cancer patients, 499 patients attending the London Regional Cancer Centre for follow-up appointments were questioned. Of the 493 patients with a family doctor, 282 (57.2%) reported that their family doctor had been involved in the diagnosis, 132 (26.8%) in the treatment, and 214 (43.4%) in the follow up. Only 60% thought that their family doctor was aware of their current problems, and only 31.4% had an appointment to see their family doctor in the near future.
