Purpose

Mammographic density (MD) is one of the strongest risk factors for breast cancer (BC). However, the influence of MD on the BC prognosis is unclear. The objective of this study was therefore to investigate whether percentage MD (PMD) is associated with a difference in disease-free or overall survival in primary BC patients.

Methods

A total of 2525 patients with primary, metastasis-free BC were followed up retrospectively for this analysis. For all patients, PMD was evaluated by two readers using a semi-automated method. The association between PMD and prognosis was evaluated using Cox regression models with disease-free survival (DFS) and overall survival (OS) as the outcome, and the following adjustments: age at diagnosis, year of diagnosis, body mass index, tumor stage, grading, lymph node status, hormone receptor and HER2 status.

Results

After median observation periods of 9.5 and 10.0 years, no influence of PMD on DFS (p = 0.46, likelihood ratio test (LRT)) or OS (p = 0.22, LRT), respectively, was found. In the initial unadjusted analysis higher PMD was associated with longer DFS and OS. The effect of PMD on DFS and OS disappeared after adjustment for age and was caused by the underlying age effect.

Conclusions

Although MD is one of the strongest independent risk factors for BC, in our collective PMD is not associated with disease-free and overall survival in patients with BC.

 Plastic and Reconstructive Surgery: June 2021 - Volume 147 - Issue 6 - p 940e-947e

 Background: 

Anatomical implants provide a wide range of options in terms of implant dimensions for breast augmentation. Nevertheless, many surgeons choose not to use anatomical implants due to the risk of rotation malposition and because their advantages over round implants are not clearly defined.

Methods: 

A retrospective review of medical records was performed on all women who underwent breast augmentation or implant exchange with microtextured anatomical implants from 2012 to 2019 in a single private clinic. The authors focused on the outcomes of a subgroup of women with glandular ptosis and nipple placement below the inframammary fold who underwent breast augmentation with anatomical implants. Furthermore, the incidence and risk factors for implant rotation were analyzed.

Results: 

In total, 653 women underwent primary breast augmentation (n = 529) or implant exchange (n = 124) with anatomical implants. The median follow-up period was 2.7 years (interquartile range, 1.6 to 3.9 years). The incidence of implant rotation was 14 (2.6 percent) in the primary augmentation group and four (3.2 percent) in the implant exchange group. Implant rotation was not associated with type of surgery (p = 0.76), implant projection (p = 0.23), or implant height (p = 0.48). The authors successfully used anatomical implants to elevate the nipple in 92.9 percent of the women with glandular ptosis without using a mastopexy.

Conclusions: 

The study results indicate that the rotation risk with microtextured implants is similar to that with macrotextured implants. Furthermore, the authors found that high-projection anatomical implants can be used as an alternative to augmentation-mastopexy in women with glandular ptosis.

Plastic and Reconstructive Surgery: June 2021 - Volume 147 - Issue 6 - p 1271-1277

Background: 

Autologous free flap breast reconstruction is a common reconstructive procedure, with the ability to produce a natural breast shape and a long history of success. Despite its benefits, there are special situations in which patients lack sufficient donor-site tissue to achieve adequate breast size and projection. With this study, the authors describe their institutional experience of delayed implant augmentation after autologous breast reconstruction with a particular focus on pedicle division as a technique to improve aesthetic results.

Methods: 

A retrospective chart review of patients that underwent free flap autologous breast reconstruction with delayed implant augmentation was conducted over a 13-year period. Flaps were divided into a control group without pedicle division and a divided pedicle group. Groups were compared in terms of demographics, clinical and surgical characteristics, implant details, and postoperative implant and flap complications.

Results: 

No significant differences in terms of age, body mass index, comorbidities, radiation therapy, or surgical indications were noted. The most common reason for delayed implant augmentation after autologous breast reconstruction was change in breast size and breast asymmetry. In terms of implant and flap complications, we found no significant differences between the control and divided pedicle groups after delayed implant augmentation.

Conclusions: 

From the authors’ institutional experience, pedicle division in delayed breast augmentation with implants after free flap breast reconstruction can be safety performed in selected cases. This technique can be a powerful tool for plastic surgeons to improve the final aesthetic appearance of the reconstructed breast.

The Breast: Published: June 11, 2021

Purpose

To identify prognostic factors of invasive–disease free survival (iDFS) in women with non-metastatic hormone receptor positive (HR+) breast cancer (BC) in daily routine practice.

Methods

We performed a retrospective study using data from the Côte d’Or breast and gynecological cancer registry in France. All women diagnosed with primary invasive non-metastatic HR + BC from 1998 to 2015 and treated by endocrine therapy (ET) were included. Women with bilateral tumors or who received ET for either metastasis or relapse were excluded. We performed adjusted survival analysis and Cox regression to identify prognostic factors of iDFS.

Results

A total of 3976 women were included. Age at diagnosis, ET class, SBR grade, treatment, stage and comorbidity were independently associated with iDFS. Women who had neither surgery nor radiotherapy had the highest risk of recurrence (HR = 3.75, 95%CI [2.65–5.32], p < 0.0001). Receiving aromatase inhibitors (AI) was associated with a lower risk of recurrence (HR = 0.80, 95%CI [0.54–0.90], p = 0.055) compared to tamoxifen. Compared to women with no comorbidities, women with 1 or 2 comorbidities were more likely to receive AI (OR = 1.63, 95%CI [1.22–2.17], p = 0.0009).

Conclusions

Comorbidities, age at diagnosis and previous treatment were associated with iDFS in non-metastatic HR + BC patients. This study also showed that women who received tamoxifen for their cancer experienced worse iDFS compared to women treated with AI.

Background

It is important to continually reevaluate the risk/benefit calculus of internal mammary node irradiation (IMNI) in the era of modern systemic therapy. We aimed to investigate the effect of IMNI on survival in node-positive breast cancer treated with mastectomy and anthracycline plus taxane-based chemotherapy.

Methods

We analyzed 348 patients who underwent mastectomy and anthracycline plus taxane-based chemotherapy for node-positive breast cancer between January 2006 and December 2011. All patients received postoperative radiation therapy (RT) with IMNI (n = 105, 30.2%) or without IMNI (n = 243, 69.8%). The benefit of IMNI for disease-free survival (DFS) and overall survival (OS) was evaluated using multivariate analysis and inverse probability of treatment weighting (IPTW) to adjust for unbalanced covariates between the groups.

Results

After a median follow-up of 95 months, the 10-year locoregional recurrence-free survival rate, DFS, and OS in all patients were 94.8%, 77.4%, and 86.2%, respectively. The IPTW-adjusted hazard ratio (HR) for the association of IMNI (vs. no IMNI) with DFS and OS was 0.208 (95% confidence intervals (CI) 0.045–0.966) and 0.460 (95% CI, 0.220–0.962), respectively. In multivariate analysis, IMNI was a favorable factor for DFS (HR, 0.458; P = 0.021) and OS (HR 0.233, P = 0.018).

Conclusions

IMNI was associated with improved DFS and OS in node-positive patients treated with mastectomy, post-mastectomy RT, and taxane-based chemotherapy, although the rate of locoregional recurrence was low.

Background: Implant-based reconstruction is the most performed breast reconstruction, and both subpectoral and prepectoral approaches can lead to excellent results. Choosing the best procedure requires a thorough understanding of every single technique, and proper patient selection is critical to achieve surgical success, in particular when dealing with prepectoral breast reconstruction.

Methods: Between January of 2014 and December of 2018, patients undergoing mastectomy and eligible for immediate prepectoral breast reconstruction with tissue expander or definitive implant, were selected. The Prepectoral Breast Reconstruction Assessment score was applied to evaluate patient-related preoperative and intraoperative risk factors that could influence the success of prepectoral breast reconstruction. All patients were scored retrospectively, and the results obtained through this assessment tool were compared to the records of the surgical procedures actually performed.

Results: Three hundred fifty-two patients were included; 112 of them underwent direct-to-implant immediate reconstruction, and 240 underwent the two-stage procedure with temporary tissue expander. According to the Prepectoral Breast Reconstruction Assessment score, direct-to-implant reconstruction should have been performed 6.2 percent times less, leading to an increase of 1.4 percent in two-stage reconstruction and 4.8 percent in submuscular implant placement.

Conclusions: To date, there is no validated system to guide surgeons in identifying the ideal patient for subcutaneous or retropectoral breast reconstruction and eventually whether she is a good candidate for direct-to-implant or two-stage reconstruction. The authors processed a simple risk-assessment score to objectively evaluate the patient’s risk factors, to standardize the decision-making process, and to identify the safest and most reliable breast reconstructive procedure.

BIA-ALCL and Textured Breast Implants: A Systematic Review of Evidence Supporting Surgical Risk Management Strategies

 

BIA-ALCL and Textured Breast Implants: A Systematic Review of Evidence Supporting Surgical Risk Management Strategies

 by Nelson, Jonas A.; McCarthy, Colleen; Dabic, Stefan; Polanco, Thais; Chilov, Marina; Mehrara, Babak J.; Disa, Joseph J

 Plastic and Reconstructive Surgery: May 2021 - Volume 147 - Issue 5S - p 7S-13S

 Background:  Breast implant–associated anaplastic large cell lymphoma (BIA-ALCL) is a significant public health concern for women with breast implants. The increase in incidence rates underscores the need for improved methods for risk reduction and risk management. The purpose of this study was to perform a systematic review to assess surgical risk reduction techniques and analyze communication/informed consent practices in patients with textured implants.

 Methods: A systematic review of the literature was conducted in PubMed (legacy), Embase (Embase.com), and Scopus with four search strategies including key terms centered around breast reconstruction and BIA-ALCL.

Results: A total of 571 articles were identified, of which 276 were included in the final review after duplicates were removed. After review, no articles were determined to fit the inclusion criteria of demonstrating data-driven evidence of BIA-ALCL risk reduction through surgical measures, demonstrating a significant lack of data on risk reduction for BIA-ALCL.

Conclusions: Risk management for BIA-ALCL is an evolving area requiring additional investigation. Although removal of textured devices in asymptomatic patients is not currently recommended by the Food and Drug Administration, variability in estimates of risk has led many patients to electively replace these implants in an effort to decrease their risk of developing BIA-ALCL. To date, however, there is no evidence supporting the concept that replacing textured implants with smooth implants reduces risk for this disease. This information should be used to aid in the informed consent process for patients presenting to discuss management of textured breast implants.

18F-FDG-PET identified patients with HER2-positive, early-stage breast cancer who were likely to benefit from chemotherapy-free dual HER2 blockade with trastuzumab and pertuzumab, and a reduced impact on global health status. Depending on the forthcoming results for the 3-year invasive disease-free survival endpoint, this strategy might be a valid approach to select patients not requiring chemotherapy.

The use of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) has proven to be a successful strategy in the treatment of advanced hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2 -) breast cancer (BC), leading to a strong interest in their possible role in the treatment of early luminal BC. In this review we collect the most relevant and recent information on the use of CDK4/6i for the treatment of early BC in the neoadjuvant and adjuvant settings. Specifically, we evaluate the results of the large phase 3 adjuvant trials recently released, which have yielded apparently divergent results.
