Obstacles in genetic testing for germline BRCA1/2 pathogenic mutations in patients with primary breast and ovarian cancer in Switzerland.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeApproximately 5-10% of breast and up to 25% of ovarian cancer cases are hereditary, predominantly associated with germline BRCA1/2 pathogenic variants. Identifying these mutations is essential for personalized treatment, prevention strategies, and cascade testing in families. However, integrating genetic testing into routine care faces substantial barriers globally and within Switzerland.
methodsThis retrospective, quantitative study analyzed 209 patients treated for non-mucinous ovarian carcinoma or primary breast cancer at the Women's Cantonal Hospital, Lucerne (2017-2022). All patients met Swiss clinical (SAKK) criteria for genetic testing, and recommendations for counseling were documented. Data were collected via anonymized questionnaires evaluating demographics, counseling experiences, emotional responses, and testing barriers. Statistical analyses examined factors influencing counseling uptake, including timing, referral source, education, and informational resources.
resultsOut of 73 respondents (32.6% response rate), 70 questionnaires were analyzed. Acceptance of genetic counseling was 81.4%. Recommendations by gynecologists significantly enhanced uptake (p = 0.002), especially when provided postoperatively or at diagnosis (p = 0.011). Higher education levels (p = 0.009) and prior informational materials (p = 0.014) positively influenced acceptance. Emotional responses differed, with breast cancer patients reporting more fear, whereas ovarian cancer patients reported greater curiosity. Family involvement supported patient engagement, while perceptions of minimal personal benefit and family disinterest were common reasons for declining.
conclusionTimely, well-communicated recommendations and informational resources significantly improve genetic counseling uptake among breast and ovarian cancer patients. Addressing systemic and patient-specific barriers will enhance equitable access, optimize targeted therapies and preventive strategies, and should be supported by national registries, qualitative research, and digital integration.
