Factors influencing medical oncology referral in Dukes' C colonic cancer

Colorectal cancer (CRC) is one of the most common malignancies worldwide and adjuvant chemotherapy is proven to improve survival in patients with Dukes' C CRC. The purpose of this study was to analyze factors influencing referral to medical oncology in patients with Dukes' C colonic cancer in our institutions.Patients who underwent resection for Dukes' C colonic cancer were assessed for factors that influence the pattern of postoperative referral to the medical oncology department, including demographic and perioperative data.Overall, 466 patients were identified to have Dukes' C colonic cancer, with 53.9% of these being female. Referral to medical oncology occurred for 58.4% patients. Multivariable logistic regression modeling identified age, elective admission and resection in private hospitals as factors. The likelihood of medical oncology referral in patients who had elective resection was 63% versus 41% in those who had emergency resection and resection in private hospitals was 69% versus 50% in public hospitals.Referral to a postoperative medical oncology clinic for adjuvant chemotherapy in Dukes' C colonic cancer was more likely in younger patients, those who underwent elective resection and those treated in private hospitals.
