Comparison of psychological distress for breast, ovarian and colorectal cancer predisposition in a Spanish sample at high risk of hereditary cancer.

Abstract

Although future treatments may speciically target the tumour phenotype, other factors should be included to confirm the efficacy of treatment and prevention strategies. The objective of this study was to compare sociodemographic characteristics and psychological distress for breast, ovarian and colorectal cancer predisposition syndrome in a sample at high risk of hereditary cancer. A cross-sectional study was designed with 799 patients. The nonparametric test, with Kruskal-Wallis test, was used to compare three genetic cancer syndromes, with significant differences in sample size. There were no differences in cancer hereditary syndromes related to sociodemographic characteristics except sex, as breast/ovarian cancer mainly affects women. No group differences were observed for cancer worry (P = 0.17). Breast/ovarian cancer syndrome showed significantly higher scores in cognitive distress compared to colorectal cancer (P = 0.01). The differences in the distribution of sociodemographic characteristics in these hereditary cancer syndromes can help to better plan resources for patient care in genetic counselling units.
