Background and Objectives: Breast reconstruction following mastectomy improves quality of life and psychosocial outcomes, yet it is not consistently performed despite multiple federal mandates. Current data shows decreased reconstruction in minority races, those with a low socioeconomic status, and those holding public health insurance. Many barriers remain misunderstood or unstudied. This study examines barriers to post-mastectomy breast reconstruction to promote a supportive clinical climate by addressing multifactorial obstacles to equitable access to care. Materials and Methods: The California Cancer Registry Data Surveillance, Epidemiology, and End Results (SEER) database and California Health and Human Services Agency Cancer Surgeries Database (2013–2021 and 2000–2021, respectively) were used in this retrospective observational study on mastectomy with immediate breast reconstruction (IBR), delayed breast reconstruction (DBR), or mastectomy only (MO) rates. Data were collected on age, sex, race, insurance type, hospital type, socioeconomic status, and residence. Pearson’s chi-square analysis was performed. Results: We found that 168,494 mastectomy and reconstruction surgeries were performed (82.36% MO, 7% IBR, 10.6% DBR). The 40–49 age group received significantly less MO (38.1%) compared to the 70–74 age group (94.8%, (p = <0.001). Significantly more reconstruction was carried out in patients with private, HMO, or PPO insurance (IBR 75.86%, DBR 75.32%, p = <0.001). Almost all breast surgeries were in urban areas as opposed to rural/isolated rural areas (96.02% vs. 1.55%, p = <0.001). There was no significant difference between races. Of all surgeries, 7.46% were completed in a cancer center with significantly higher rates of IBR. LA County, San Luis Obispo/Ventura County, and Northern CA had significantly more MO than other regions (p = <0.001). Conclusions: Reconstruction rates after mastectomy are low, with only 17.64% of patients undergoing reconstruction. Nationally, 70.5% of patients received MO, with 29.6% undergoing reconstruction. Significant factors positively contributing to reconstruction were private insurance, high SES, cancer center care, and urban residency. Identified barriers include public health insurance enrollment, rural or non-urban residence, older age, low SES, and non-white race/ethnicity, indicating potential monetary influences on care.

Background and Objectives: Breast cancer-related lymphedema (BCRL) is a complication of axillary lymph node dissection (ALND). Immediate lymphatic reconstruction (ILR) may help to decrease lymphedema after ALND by creating lymphatic bypasses. This retrospective single-institution study aimed to compare lymphedema in patients undergoing ALND with and without ILR. Materials and Methods: Bioimpedance and limb measurements determined the presence of BCRL. The categorical data that were collected and analyzed included BMI, comorbidities, BCRL onset, and number of lymphatic bypasses. Pearson’s chi-square test and multivariable logistic regression were performed to identify factors associated with the onset of lymphedema. An odds ratio compared the incidence of BCRL with and without ILR. Results: In total, 186 patients underwent ALND, 44 (24%) with ILR and 142 (76%) without. The mean number of bypasses during ILRs created was 3.54. The odds of developing lymphedema with ILR were 64% lower than for ALND alone. ILR patients who developed BCRL had a mean onset of 543 days post-operatively versus 389 days in the control group. Age, ethnicity, BMI, and bypass amount had no significant influence on lymphedema development. Conclusions: ILR was associated with lower rates of BCRL after ALND. Patients who developed lymphedema despite undergoing ILR did so 8 months later than the controls.

Background: Implant-based reconstruction (IBR) is the most common method of breast reconstruction, but complications lead to patient distress and delays in cancer treatment. Management of implant complications is varied with no defined guidelines. The inability to salvage IBR is associated with infection, but the impact of antibiotics remains controversial. We aimed to analyze factors affecting salvage rates of threatened IBR requiring operative intervention. The primary outcomes were the rates of unplanned re-operation for threatened IBR for wound closure, exchange, or explant. We hypothesized antibiotic administration would improve salvage rates. Methods: A retrospective review of patients undergoing mastectomy with IBR from 2012 to 2023 was performed. Threatened IBR was defined as implant exposure, infection, skin necrosis, hematoma, seroma, or wound dehiscence without implant exposure. Management options for patients with implant infection included implant removal and antibiotic treatment, antibiotic treatment alone, implant replacement, washout and implant replacement, or implant removal without a salvage attempt. Results: In total, 6901 patients underwent post-mastectomy IBR, and 184 (2.7%) patients had an unplanned re-operation. A total of 166/184 patients (90.2%) underwent explantation, and 18/184 (9.8%) patients had implant salvage. Between the explant and salvage groups, there were no differences in patient demographics, oncologic treatments, or operative characteristics. The explant group had a higher rate of infection (77.7% vs. 22.2%, p < 0.0001). There was no difference in culture positivity or antibiotic administration history. Conclusions: Implant salvage is feasible but limited by infection. Antibiotic administration does not improve salvage rates. Patient factors, oncologic treatment factors, or operative factors do not impact the ability to salvage.

Background: Implant-based reconstruction (IBR) is the most common method of breast reconstruction after mastectomy. Prior studies have demonstrated that complications rates vary with incision type. We evaluated whether incision type affected culture positivity in IBR complications. Methods: A retrospective cohort study was performed of all patients undergoing mastectomy for cancer or cancer prophylaxis with IBR from 2012 to 2023. Abstracted data included patient characteristics, oncologic treatment history, mastectomy and reconstruction characteristics, culture positivity, infectious organism, and antibiotic treatment history. Results: A total of 6901 patients underwent post-mastectomy implant-based reconstruction, 183 (2.7%) patients had unplanned operative intervention for IBR complications, and 80/183 (43.7%) had culture-positive IBR infections. Culture-negative and culture-positive groups were similar in patient characteristics and oncologic treatment history. There was no difference in mastectomy incision types. The most common organisms were methicillin-sensitive Staphylococcus aureus, Pseudomonas aeruginosa, and coagulase-negative Staphylococcus. More patients in the culture-positive group were treated with antibiotics (81.2% vs. 51.5%, p = 0.0005). Antibiotic therapy duration was longer in the culture-negative group (8.52 vs. 5.78 days, p = 0.039). Among different incision types, there was no significant difference in duration of antibiotic therapy. Conclusions: No association between mastectomy incision type and culture-positive infections was observed among IBR complications in this study. Antibiotics may sterilize cultures, but operative intervention is still often required for IBR infections.
