Abstract

AbstractHereditary cancer refers to cancers caused by germline mutations in cancer predisposing genes. These mutations confer a significantly increased risk of cancer, are rare, and are in the majority of cases autosomal dominantly inherited.  Since the eighties of last century more than 115 cancer predisposing genes have been identified. In many Western countries genetic testing of patients and families with clustering of cancers started early, and was often performed by clinical geneticists (MDs performed the counselling and pedigree analyses) and by molecular biologists (in laboratories within departments of clinical genetics).  It turned out to be a long path to fully realize the promise of cancer predisposing genes. The clinical utility of many cancer genetic tests and subsequent risk reducing interventions has not yet been validated and pitfalls in e.g. misinterpretation of genetic variants showed up. However, without doubt genetic testing for mutations will eventually turn out as a strong tool to save lives from early cancer death and will become part of standard cancer care throughout the developed world.  Apart from primary surgical prevention, major progress is to be expected in earlier diagnoses, tailored therapies, and possibly chemoprevention.  Ideally researchers, clinical geneticists, molecular biologists, surgeons, oncologists, gynaecologists and other professionals will work together to reach this goal.

Abstract

AbstractEurope has contributed to the majority of high-impact papers on genes and risk alleles in breast cancer and ovarian cancer susceptibility. Consortia like the Breast Cancer Linkage Consortium, Breast Cancer Association Consortium, and the Consortium of Investigators on Modifying genes in BRCA1/2, started from the nineties of the last century on.  Many highly motivated participants throughout Europe, the US, Australia and elsewhere contributed to the formation of huge datasets. Instrumental of the success of the consortia was also the leadership and knowledge of Dough Easton, UK, on the statistics of cancer genetics. The consortia papers have produced the data on which national guidelines in HBOC were formulated in West-Europe, the US and worldwide.   Genetic testing for HBOC is in most Western-European countries accepted and funded. Two decades after the identification of BRCA1 and BRCA2, attitudes towards genetic testing for HBOC are changing and becoming more ‘common’ practice. This offers opportunities to organize cancer genetic care more efficiently and at lower costs while informed decision making and consent of the patients remain in place.
