P1056: NEXT GENERATION SEQUENCING IDENTIFIES SUBGROUPS OF PATIENTS WITH TRIPLE NEGATIVE/ PRIMARY THROMBOCYTOSIS WITH DIFFERENT CLINICAL OUTCOMES
Evaluation of family history in individuals with heterozygous BRCA pathogenic variants diagnosed with breast or ovarian cancer in a single center in Italy
Abstract Background BRCA1 and BRCA2 gene mutations are responsible for 5% of breast cancer (BC) and 10â15% of ovarian cancer (EOC). The presence of a germline mutation and therefore the identification of subjects at high risk of developing cancer should ideally precede the onset of the disease, so that appropriate surveillance and riskâreducing treatments can be proposed. In this study, we revisited the family history (FH) of women who tested positive for BRCA mutations after being diagnosed with BC or EOC. Methods The National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology (NCCN GuidelinesÂź), and the Italian Association of Medical Oncology (AIOM) guidelines were applied to the FH of 157 women who were referred to San Gerardo Hospital for genetic counseling. Results Almost 85% of women had an FH of BRCAârelated cancer. 63.7% and 52.2% of women could have undergone genetic testing according to NCCN and AIOM testing criteria (pâ<â.05) before tumor diagnosis. An FH of EOC was the most frequent NCCN criterion, followed by BC diagnosed <45âyears old. Sixtyâfive percent of deceased women could have undergone genetic testing before developing cancer. Conclusions FH is a powerful tool to identify highârisk individuals eligible for genetic counseling and testing. Testing of healthy individuals should be considered when an appropriately affected family member is unavailable for testing

Numerical modeling of hemodynamics scenarios of patient-specific coronary artery bypass grafts
A fast computational framework is devised to the study of several configurations of patient-specific coronary artery bypass grafts. This is especially useful to perform a sensitivity analysis of the hemodynamics for different flow conditions occurring in native coronary arteries and bypass grafts, the investigation of the progression of the coronary artery disease and the choice of the most appropriate surgical procedure. A complete pipeline, from the acquisition of patient-specific medical images to fast parameterized computational simulations, is proposed. Complex surgical configurations employed in the clinical practice, such as Y-grafts and sequential grafts, are studied. A virtual surgery platform based on model reduction of unsteady Navier-Stokes equations for blood dynamics is proposed to carry out sensitivity analyses in a very rapid and reliable way. A specialized geometrical parameterization is employed to compare the effect of stenosis and anastomosis variation on the outcome of the surgery in several relevant cases
