Expectations and psychological issues before genetic counseling: analysis of distress determinant factors.

Background: Hereditary non-polyposis colorectal cancer (HNPCC) and Hereditary Breast and Ovarian Cancer Syndrome (HBOC) are the most common hereditary cancer syndromes in which a genetic test is available. Potential risks associated with testing include psychological harm, emotional distress and insurance problems.

Methods: The aim of the present study is to investigate determinants of distress in a sample of Italian subjects undergoing genetic counseling. Demographic information and psychological distress were assessed by using a self-reported questionnaire and the "Hospital Anxiety and Depression Scale" (HAD), before attending the first counseling session.

Results: Of the all subjects referred for the first time to our Center (January 2012-June 2013), a total of 227 were eligible (female/male = 174/53) for the survey, 134 (59%) were oncologic patients and of these, 116 received genetic test (36 for HNPCC and 80 for HBOC). The remaining 93 (41%) were healthy subjects referred for suspected familiar history and of this group, 65 subjects performed predictive test in a family with a known pathogenic mutation (53 for HBOC and 12 for HNPCC). Affected subjects had a significantly higher level of anxiety ( = 0.02) and HAD global score ( = 0.01) than healthy ones. There was no difference in HAD score between individuals testing for different syndromes ( = 0.3). In the affected subgroup, there was a significant linear correlation between the HAD anxiety score and how much subjects perceived their disease as hereditary ( = 0.01). Female and younger subjects had higher levels of anxiety ( = 0.05). Also healthy single subjects show more general distress ( = 0.02) than those with a partner.

Conclusions: Greater level of distress identified on females, single and younger subjects.
