Five Years of Multidisciplinary Care in Hereditary Cancer: Our Experience in a Spanish University Hospital

Abstract

Objective: To analyse the evolution of a multidisciplinary heredofamilial cancer unit (HFCU) in a university hospital. Methods: This was a retrospective analysis of the activity of our HFCU in its first 5 years of existence. Results: Between July 2010 and July 2015, 1,518 patients from 1,318 families attended our HFCU. Genetic testing was offered to 862 patients. Of those, 833 (96.6%) accepted testing, with available results for 636 (76.4%). Pathogenic mutations in BRCA1 and BRCA2 were found in 175 patients. Lynch syndrome and adenomatous polyposis were the most frequent syndromes diagnosed (151/175, 86.3%) among 17 different syndromes studied. Of the 404 patients without a previous genetic diagnosis in the family, 62 (15.3%) were found to have mutations in disease-causing genes. Prophylactic surgery and follow-up (33.7%) or follow-up only (66.3%) was proposed for mutation carriers according to international guidelines and patients' preferences. Conclusion: We have a high mutation detection rate, genetic test acceptance, and compliance with risk reduction strategies. However, there is room for improvement, especially in genetic testing timing, considering that an increase in the indications for genetic testing is expected.

“…Another frequent answer was economic limitations since the molecular test was not free of charge in the early stages of the study. For example, in a study by Márquez-Rodas, the acceptance rate for hereditary cancer was >95 % due to proper genetic counseling, but also full coverage of expenses with the Madrid health system [ 29 ].…”
