[Consensus on hereditary cancer between the Spanish Oncology Society and the primary care societies].

Introduction: It is believed that 5% of all cancers are hereditary, on being caused by mutations in the germinal line in cancer susceptibility genes. The hereditary pattern in the majority of cases is autosomal dominant. Genetic tests are only recommended to individuals whose personal or family history is highly suggestive of a hereditary cancer. The appropriate assessment of these individuals and their families must be performed in Cancer Genetic Counselling Units (UCGC).

Material And Methods: Representatives of the Spanish Medical Oncology Society (Sociedad Española de Oncología Médica [SEOM]) and the three primary care scientific societies: Spanish Society of Family and Community Medicine (Sociedad Española de Medicina de Familia y Comunitaria [SEMFyC]), Spanish Society of Primary Care Physicians (Sociedad Española de Médicos de Atención Primaria [SEMERGEN]) and the Spanish Society of General and Family Doctors (Sociedad Española de Médicos Generales y de Familia [SEMG]), met to prepare this consensus document on hereditary cancer. The consensus identified the three main aspects: how to identify subjects at risk of hereditary cancer; how to refer to a UCGC; and the usefulness of the assessment and genetic studies.

Results: A document, with the text fully agreed by all the participants, has been prepared. It contains a summary of the principal characteristics of the care for individuals with hereditary cancer. It shows how to; identify them, assess them, refer them to a UCGC. How to assess their genetic risk, perform genetic studies, as well as prevention measures and reduction of the risk is also presented.

Conclusions: This consensus document is a landmark in the relationships with several Scientific Societies that represent the professionals who provide care to individuals with cancer and their families, and will help to improve care in hereditary cancer in Spain.
