Women's Knowledge of Genomic Testing and Precision Medicine in Breast Cancer Treatment Decision-Making.

PURPOSE: To understand awareness of genetic and genomic testing, as well as decision-making, in women diagnosed with breast cancer. PARTICIPANTS & SETTING: 29 African American/Black and Latina/Hispanic women diagnosed with breast cancer. METHODOLOGIC APPROACH: A semistructured interview guide was used in focus groups conducted via videoconference. Transcripts were analyzed using thematic analysis. FINDINGS: Many of the women understood the concept of genetic testing to identify the BRCA1/BRCA2 variant, but none of them were aware of genomic testing and its implications for personalized medicine. Participants discussed provider and patient roles in treatment decision-making, identifying roles that the physician might play in treatment planning, from primary decision-maker to collaborator. IMPLICATIONS FOR NURSING: As the number of precision cancer treatments expands, patients must be able to comprehend the information provided to make informed decisions about their treatment. Providers should do a better job of explaining potential treatments so that patients feel they are part of the decision-making process. Addressing gaps in treatment access and uptake requires providers to prioritize patient engagement and understanding.

Arrhythmia recurrence in adult patients with single ventricle physiology following surgical Fontan conversion.

OBJECTIVES: To evaluate the incidence of atrial tachy-arrhythmia (AT) recurrence following conversion from right atrial-pulmonary artery (RA-PA) Fontan to total cavopulmonary connection (TCPC) in adults. BACKGROUND: AT is a recognized sequel of Fontan palliation, especially in RA-PA Fontans, and is associated with significant morbidity. While catheter ablation achieves fairly reliable short-term success with low morbidity, conversion to TCPC with arrhythmia surgery is a highly effective treatment option for the classical Fontan patients with incessant AT. METHODS: Single center retrospective review. RESULTS: Twenty-seven adults underwent Fontan conversion from RA-PA to TCPC, mostly for AT indications (n = 24). Nine (33%) underwent conversion to a lateral tunnel (LT) and 18 (67%) to an extracardiac (EC) Fontan. Two patients died <30 days post-operatively. Both had liver failure and had been turned down for cardiac/liver transplantation. In-hospital complications occurred in 15/27 patients (55%), including recurrence of AT requiring cardioversion in six patients (22%) and persistent pleural effusions in 4 (15%). Mean follow-up was 4.2 years (range 3 months-14 years). Functional capacity improved from mean New York Heart Association (NYHA) class 1.8 pre-conversion to 1.2 post-conversion (P= 0.008). Twenty-one patients had concomitant arrhythmia surgery (MAZE in 12 patients with IART and Cox-MAZE in nine patients with A-Fib +/- IART). Of these, 3/21 (14%) had AT recurrence >3 months following conversion. CONCLUSIONS: Conversion from RA-PA Fontan to TCPC, with arrhythmia surgery, decreases AT recurrence and improves functional capacity. The risk of peri-operative mortality is highest in patients with cirrhosis. AT recurred in 14% of patients.
