Patient-reported outcomes post prophylactic risk-reducing mastectomy: improved breast and psychosocial satisfaction yet poorer physical well-being.

BACKGROUND: Few studies have investigated patient-reported outcomes (PROs) for patients with high breast cancer risk undergoing elective risk reduction mastectomy and reconstruction. These patients incur operative risk in the absence of active cancer, which renders their treatment experience unique. This study aimed to identify longer-term quality of life (QoL) issues that persist in this patient cohort. METHODS: A cross-sectional cohort study assessed PROs in 48 women with high breast cancer risk who attended the Royal Melbourne Hospital Risk Management Clinic, at least 12 months post-mastectomy and reconstruction, with surgery between 2011 and 2020, using the BREAST-Q© Likert surveys. The BREAST-Q© internationally validated QoL instrument scales survey data from 0 (worst) to 100 (best) in 14 domains addressing satisfaction and psychosocial issues. RESULTS: There was higher overall breast and psychosocial satisfaction, with scores of 11 and four, respectively, yet lower chest, abdomen and sexual well-being scores with 14, three and four, respectively, in contrast to normative BREAST-Q© data from >1000 women without prior breast cancer or breast operations. High average scores >90 were found for patient satisfaction with surgical, medical and office staff. Twenty-one patients had an average score of 63 for satisfaction with breast implants, while 27 patients post-DIEP had average scores >72 for abdominal well-being, appearance and overall outcomes. Higher mean QoL outcomes were found with DIEP flap in all domains, compared with breast implant reconstruction. CONCLUSION: QoL assessment with PROs 12 months post-risk reduction mastectomy and reconstruction demonstrated higher psychosocial well-being, yet highlights physical implications, with patients experiencing reduced chest, abdomen and sexual well-being, compared with normative BREAST-Q© control data. Higher mean QoL outcomes were found with DIEP flap compared with breast implant reconstruction. PROs studies can identify unmet needs and facilitate change in service provision.

Outcomes of women at high familial risk for breast cancer: An 8-year single-center experience.

OBJECTIVES: The value of a high-risk surveillance program for mutation carriers and women at high familial breast cancer risk has not been extensively studied. A Breast and Ovarian Cancer Risk Management Clinic (BOCRMC) was established at the Royal Melbourne Hospital in 2010 to provide multimodality screening and risk management strategies for this group of women. The aims of this study were to evaluate the program and describe breast cancer diagnoses for BRCA1, BRCA2, and other germline mutation carriers as well as high-risk noncarriers attending the BOCRMC. METHODS: Clinical data from mutation carriers and noncarriers with a ≥25% lifetime risk of developing breast cancer who attended between 2010 and 2018 were extracted from clinic records and compared. The pattern and mode of detection of cancer were determined. RESULTS: A total of 206 mutation carriers and 305 noncarriers attended the BOCRMC and underwent screening on at least one occasion. Median age was 37 years. After a median follow-up of 34 months, 15 (seven invasive) breast cancers were identified in mutation carriers, with seven (six invasive) breast cancers identified in noncarriers. Of these, 20 (90.9%) were detected by annual screening, whereas two (9.1%) were detected as interval cancers (both in BRCA1 mutation carriers). Median size of the invasive breast cancers was 11 mm (range: 1.5-30 mm). The majority (76.9%) were axillary node negative. In women aged 25-49 years, the annualized cancer incidence was 1.6% in BRCA1, 1.4% in BRCA2 mutation carriers, and 0.5% in noncarriers. This compares to 0.06% annualized cancer incidence in the general Australian population. CONCLUSIONS: Screening was effective at detecting early-stage cancers. The incidence of events in young noncarriers was substantially higher than in the general population. This potentially justifies ongoing management through a specialty clinic, although further research to better personalize risk assessment in noncarriers is required.
