Autologous Fat Grafting Does Not Increase Risk of Oncologic Recurrence in the Reconstructed Breast.

INTRODUCTION: Autologous fat grafting (AFG) is a popular and effective method of breast reconstruction after mastectomy; however, the oncological safety of AFG remains in question. The aim of this study was to determine whether AFG increases the risk of cancer recurrence in the reconstructed breast. METHODS: A matched, case-control study was conducted from 2000 to 2017 at the senior author's institution. Inclusion was limited to female patients who underwent mastectomy and breast reconstruction with or without AFG. Data were further subdivided at the breast level. χ analyses were used to test the association between AFG status and oncologic recurrence. A Cox proportional-hazards model was constructed to assess for possible differences in time to oncologic recurrence. The probability of recurrence was determined by Kaplan-Meier analyses and confirmed with log-rank testing. RESULTS: Overall, 428 breasts met study criteria. Of those, 116 breasts (27.1%) received AFG, whereas 312 (72.9%) did not. No differences in the rates of oncologic recurrence were found between the groups (8.2% vs 9.0%, P < 1.000). Unadjusted (hazard ratio = 1.03, confidence interval = 0.41-2.60, P < 0.957) and adjusted hazard models showed no statistically significant increase in time to oncologic recurrence when comparing AFG to non-AFG. In addition, no statistical differences in disease-free survival were found (P = 0.96 by log rank test). CONCLUSION: Autologous fat grafting for breast reconstruction is oncologically safe and does not increase the likelihood of oncologic recurrence. Larger studies (eg, meta analyses) with longer follow-up are needed to further elucidate the long-term safety of AFG as a reconstructive adjunct.

Appalachian Status Is a Negative Predictor of Breast Reconstruction Following Breast Cancer Resection.

BACKGROUND: Health care disparities in Appalachia are well documented. However, no previous studies have examined possible differences in the utilization of breast reconstruction (BR) in Appalachia. This study aims to determine if a disparity in BR utilization exists in women from Appalachia Kentucky. METHODS: A retrospective, population-based cohort study was conducted from January 1, 2006, to December 31, 2015. The Kentucky Cancer Registry was queried to identify population-level data for female patients diagnosed with breast cancer and treated with mastectomy. A multivariate logistic regression model controlling for patient, disease, and treatment characteristics was constructed to predict the likelihood of BR. RESULTS: Bivariate testing showed differences (P < 0.0001) in BR utilization between Appalachian and non-Appalachian women in Kentucky (15.0% and 26.3%, respectively). Multivariate analysis showed that women from Appalachia (odds ratio, 0.54; confidence interval (95), 0.48-0.61; P < 0.0001) were less likely to undergo BR than non-Appalachian women. Interestingly, the rate of BR increased over time in both Appalachian (r = 0.115; P < 0.0001) and non-Appalachian women (r = 0.148; P < 0.0001). CONCLUSIONS: Despite the benefits of BR, women from Appalachia undergo BR at lower rates and are less likely to receive BR than non-Appalachian Kentuckians. Although the rates of BR increased over time in both populations, access to comprehensive breast cancer care remains a challenge for women from Kentucky's Appalachian region.

Necrotic Granulomatous Inflammation after Use of Small Intestine Submucosa Matrix for Recurrent Compression Neuropathy.

Various techniques exist for treating recurrent carpal and ulnar tunnel syndrome, but AxoGuard nerve wrap has shown promising results for treatment of compression neuropathies when used in conjunction with neurolysis and tenosynovectomy. Prior results demonstrate no safety concerns, and there have not been any reported cases of infection, persistent inflammation, or recurrent perineural fibrosis. A 41-year-old, right-hand-dominant woman experienced repeated bouts of carpal and ulnar tunnel syndromes, which were treated with a small intestine submucosa matrix wrap around the median and ulnar nerves in the wrist. Here, we report a case of necrotic granulomatous inflammation 2.5 months after AxoGuard xenograft nerve wrap was placed around the median and ulnar nerves. As a salvage, NuShield placental allograft was wrapped around the median nerve, which has shown promising results at several months follow-up. Placental allograft nerve wraps represent a useful tool in compression neuropathy resistant to autografts, xenografts, and revision decompression operations.

Trends in the Surgical Management of Lower Extremity Gustilo Type IIIB/IIIC Injuries.

BACKGROUND: Over the past 20 years, innovations in microsurgical technique have coincided with advances in orthoplastic approaches. However, no single algorithm exists to guide management of limb salvage versus amputation. As such, one would expect these procedures to be performed at equal rates given studies showing similar outcomes. Anecdotally, the observation at the authors' institution is that amputations are being performed more frequently. The purpose of this study was to determine trends in lower extremity trauma management. METHODS: A retrospective cohort study was conducted at a Level I trauma center on patients with Gustilo type IIIB/IIIC lower extremity trauma from 2005 to 2014. Overall, 148 patients were included. Patients were subdivided into amputation (n = 69) and reconstruction (n = 79) cohorts. The Spearman rank correlation coefficient was used to compare trends in amputation and reconstruction groups. Plastic surgery consultation data were analyzed using the Mann-Whitney U and chi-square tests and the Pearson correlation coefficient. RESULTS: Amputation was performed more frequently over the study period (r = 0.292; p < 0.001). Plastic surgeons were consulted in 67.5 percent of cases. A plastic surgery consultation was obtained in only 30 percent of amputation cases (p < 0.001). CONCLUSIONS: Although the data show a trend toward amputation and a shift in management of lower extremity trauma, the observed trend may be attributable in part to deviation from an orthoplastic approach to lower extremity trauma. However, lower extremity reconstruction remains a viable option in select patients, and advances in microsurgery can provide excellent outcomes in the face of severe lower extremity trauma.

Rural-Urban Differences in Breast Reconstruction Utilization Following Oncologic Resection.

BACKGROUND: Breast reconstruction (BR) is the reconstructive surgical technique that focuses on restoring normal form and function to the breast following oncologic resection. The goal of this study was to determine if BR disparities exist among rural female patients in Kentucky. METHODS: A retrospective (2006-2015), population-based cohort study was conducted on breast cancer patients (stages I-III) treated with mastectomy with or without BR. We used 2013 Beale codes to stratify patients according to geographic status. Chi-square tests were used to examine the association of BR along the rural-urban continuum. A multivariate logistic regression model controlling for patient, disease, and treatment factors was used to predict BR. The likelihood of BR was reported in odds ratios (OR) using a 95% confidence interval (CI). RESULTS: Overall, 10,032 patients met study criteria. Of those, 2,159 (21.5%) underwent BR. The rate of BR among urban, near-metro, and rural patients was 31.1%, 20.4%, and 13.4%, respectively (P < .001). Multivariate analysis revealed that women from near metro (OR 0.54, CI: 0.47-0.61; P < .001) and rural areas (OR 0.36, CI: 0.31-0.41; P < .001) were less likely to undergo BR than women from urban areas. CONCLUSION: Although BR benefits are well documented, women from rural Kentucky undergo BR at lower rates and are less likely to receive BR than their urban counterparts. Efforts should seek to promote equitable access to BR for all patients, including those from rural areas.
