Objective: To better understand the long-term patient-reported outcomes (PROs) in satisfaction and health-related quality of life (QOL) following post-mastectomy reconstruction (PMR) using BREAST-Q, comparing PROs from patients undergoing implant-based breast (IBR) or autologous (ABR). Summary Background Data: Multiple studies have demonstrated growth mastectomy rates concurrent increase PMR utilization. However, most examining focus on short postoperative time periods—mainly within 2 years....

Objective: This study sought to estimate the incidence and rate of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) at a high-volume single institution, which enables vigorous long-term follow-up implant tracking for more accurate estimates. Summary Background Data: The reported BIA-ALCL is highly variable, ranging from 1 in 355 30,000 patients, demonstrating need Methods: All patients who underwent implant-based reconstruction 1991 2017 were retrospectively identified....

Background: Prepectoral placement of tissue expanders for two-stage implant-based breast reconstruction potentially minimizes chest wall morbidity and postoperative pain. The authors explored 90-day clinical health-related quality-of-life outcomes prepectoral versus subpectoral expander reconstruction. Methods: conducted a propensity score-matching analysis (nearest neighbor, 1:1 matching without replacement) patients who underwent immediate or between December 2017 January 2019. Matched...

We examined racial/ethnic disparities for COVID-19 seroconversion and hospitalization within a prospective cohort (n = 6,740) in the United States enrolled March 2020 followed-up through October 2021. Potential SARS-CoV-2 exposure, susceptibility to complications, access healthcare varied by race/ethnicity. Hispanic Black non-Hispanic participants had more exposure risk difficulty with than white participants. Participants greater odds of seroconversion. barriers hospitalization....

Breast-implant-associated anaplastic large cell lymphoma (BIA-ALCL) is associated with prolonged exposure to textured implants. Current studies describing implant use are limited single center/surgeon experiences. Using the Tracking Operations and Outcomes for Plastic Surgeons database, study aims characterize national trends in rates of smooth versus utilization. The hypothesis that have decreased most recent time period.Tracking was queried from 2007 2019 CPT codes involving breast...

Abstract The reversibility of the procancer effects obesity was interrogated in formerly obese C57BL/6 mice that lost weight via a nonrestricted low-fat diet (LFD) or 3 distinct calorie-restricted (CR) regimens (low-fat CR, Mediterranean-style intermittent CR). These mice, along with continuously and lean control were orthotopically injected E0771 cells, mouse model triple-negative breast cancer. Tumor weight, systemic cytokines, incidence lung metastases elevated LFD relative to CR groups....

Background: Despite reports demonstrating feasibility of immediate dental implant placement in mandibular reconstruction with free fibula flaps for benign disease, this practice is not routinely used the oncologic setting. The authors aim to demonstrate safety mandible reconstruction. Methods: In 2017, authors’ center began patients undergoing mandibulectomy Immediate were compared a historical cohort also reconstructed computer-aided design and manufacturing technology beginning 2011 ( n =...

Background: Radiation therapy is increasingly used after breast cancer surgery, which may impact patients’ postoperative quality of life. This study assessed differences in long-term patient satisfaction and health-related life radiation administered at different stages implant-based reconstruction or with no surgery. Methods: In this observational study, outcomes were evaluated for four cohorts women who completed received (1) radiation, (2) before tissue expander placement, (3) (4)...

Background: The association between textured surface breast implants and implant-associated anaplastic large cell lymphoma has led to an increase in surgical procedures exchange devices smooth implants. Because patient satisfaction is integral part of reconstruction, the purpose this study was compare patient-reported outcomes implant recipients. Methods: Patients aged 18 years or older who underwent implant-based postmastectomy reconstruction with either from 2009 2017 completed BREAST-Q...

Background: Rates of autologous breast reconstruction are stagnant compared with prosthetic techniques. Insufficient physician payment for microsurgical is one possible explanation. The difference between governmental and commercial payers creates a natural experiment to evaluate its impact on method reconstruction. This study assessed the influence differences implants by insurance type likelihood undergoing Methods: Massachusetts All-Payer Claims Database was queried women immediate or...

Background Tissue expanders (TE) are routinely placed as a first step in breast reconstruction for women who require post-mastectomy radiation therapy (PMRT). The final can then be performed with implants or conversion to autologous tissues. purpose of this study was compare patient-reported outcomes and surgical complications (ABR) versus implant-based (IBR) patients following TE-PMRT.
