Trans-Vertical Mastectomy With Immediate Implant-Based Reconstruction: A Retrospective, Observational Study

Best Practices for BREAST-Q Research: A Systematic Review of Study Methodology

BACKGROUND

Data heterogeneity and methodologic errors hinder the ability to draw clinically meaningful conclusions from studies using the BREAST-Q Reconstruction Module patient-reported outcome measure. In this systematic review, the authors evaluate the quality of BREAST-Q Reconstruction Module administration in relation to the BREAST-Q version 2.0 user's guide and the reporting of key methodology characteristics. The authors also describe a framework for improving the quality of BREAST-Q data analysis and reporting.

METHODS

The authors conducted a systematic search of PubMed, Embase, Cochrane CENTRAL, and Ovid HAPI databases to identify articles on the BREAST-Q Reconstruction Module to assess postmastectomy breast reconstruction outcomes. The authors registered the protocol before study implementation on Open Science Framework ( https://osf.io/c5236 ) and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data on mode of BREAST-Q administration, time horizon justification, and sample size calculation were collected.

RESULTS

The authors included 185 studies in the analysis. Errors in BREAST-Q administration were identified in 36 studies (19.5 percent). Appropriate administration of the BREAST-Q could not be determined in 63 studies (34.1 percent) because of insufficient reporting. Time horizon for the primary outcome was reported in 71 studies (38.4 percent), with only 17 (9.2 percent) reporting a sample size calculation.

CONCLUSIONS

The authors identified important yet actionable shortcomings in the BREAST-Q literature. Researchers are encouraged to review the BREAST-Q user's guide in the study design phase to mitigate errors in patient-reported outcome measure administration and reporting for future trials using the BREAST-Q Reconstruction Module. Adhering to these guidelines will allow for greater clinical utility and generalizability of BREAST-Q research.

Meshed Acellular Dermal Matrix in Immediate Prepectoral Implant-based Breast Reconstruction

Prepectoral implant placement has many potential advantages in immediate breast reconstruction. Acellular dermal matrices (ADMs) are commonly used in these surgeries. ADM meshing may enhance integration, decrease seroma and infection rates, and reduce surgical costs.

METHODS

This was a retrospective, single-center study of 49 women (71 breasts) undergoing immediate, prepectoral, implant-based breast reconstruction with 2:1 meshed, bovine-derived ADM (SurgiMend). Outcomes were compared against those of 77 patients (105 breasts) undergoing a similar procedure but with partial subpectoral implant placement.

RESULTS

In the prepectoral group, the mean age was 49.1 years and mean body mass index was 24.7 kg/m². There were no significant differences in baseline characteristics versus the partial subpectoral control group. Mean follow-up was 18.6 months (prepectoral) and 21.3 months (partial subpectoral). Mean time to drain removal was reduced in the prepectoral group (6.5 versus 8.5 days; P < 0.001). Rates of minor and major complications with prepectoral implant placement were 15.5% and 11.3%, respectively - similar to partial subpectoral placement (15.2% and 14.3%) (overall P = 0.690). Capsular contracture and explantation were associated with radiation therapy, and rates were similar between groups.

CONCLUSIONS

Prepectoral implant placement with meshed ADM is a safe and reproducible alternative to partial muscle coverage with meshed ADM. Recovery may be easier and animation deformity avoided. It could therefore become the standard of care for implant-based breast reconstruction.

The Bell Pattern: A Novel Breast Incision Approach to Skin-Reducing Mastectomies

Background

As immediate direct to permanent implant-based breast reconstruction (IBBR) continues to gain in popularity, surgeons seek to apply these techniques to patients with large or ptotic breasts. A new bell pattern skin excision is described and limits major complications in this high-risk population.

Objective

The authors describe a novel skin excision pattern for patients with large or ptotic breasts who desire IBBR and assess its safety. The authors also evaluated the ability of the pattern to account for intraoperative developments.

Methods

This retrospective analysis of a single surgeon’s experience included 17 consecutive patients (31 breasts) with large or ptotic breasts undergoing skin-reducing mastectomy with attempted utilization of the bell pattern approach and IBBR with acellular dermal matrix.

Results

Mean age was 50 years, mean body mass index was 27.4 kg/m², and mean breast specimen weight was 683 g. A bell pattern excision was planned for all breasts preoperatively. Three breasts (10%) required an alternative closure pattern due to intraoperative ischemia (n = 1), or additional oncologic resection (n = 2). The pattern successfully accommodated flap ischemia in 8 (26%) other breasts. After a median follow-up of 5.1 months, the number of bell pattern breasts with major and minor complications was 0 (0%) and 9 (32%), respectively. The most common minor complication was seroma (n = 5, 18%), and minor incision wound (n = 3, 11%). There were no reconstruction failures utilizing the bell pattern.

Conclusion

The bell pattern approach is a safe and adaptable alternative to traditional skin-reducing mastectomy in patients with large or ptotic breasts.
