Superior Sensibility after Full Breast Reconstruction with Autologous Fat Transfer.

ABSTRACT:

Background

With developments in screening and treatment, survival rates of breast cancer patients are increasing, and so is the number of women opting for breast reconstruction to improve their quality of life. One factor that could play an important role in improving the quality of life is breast sensibility. Therefore, the aim of this study was to explore breast sensibility in participants of the Breast Reconstruction with External Preexpansion and Autologous Fat Transfer versus Standard Therapy trial: an ongoing randomized controlled trial comparing breast reconstruction with autologous fat transfer (AFT) versus implant-based reconstruction (IBR).

Methods

This study was conducted on participants of the Breast Reconstruction with External Preexpansion and Autologous Fat Transfer versus Standard Therapy trial who were at least 12 months after final surgery. Semmes-Weinstein monofilaments were used to measure skin sensibility in breast cancer patients who underwent breast reconstruction with either AFT or IBR following their mastectomy.

Results

A total of 46 patients were included in this study, resulting in 62 breast reconstructions (28 AFT breasts and 34 IBR breasts). Significantly higher mean monofilament values were found for skin sensibility after AFT (-0.7; P < 0.001), clinically correlating to "diminished protective function," as opposed to the IBR group, with clinical values indicating "loss of protective function."

Conclusions

In this study, the authors found that breast cancer patients who underwent a mastectomy had a significantly better sensibility of the breast following AFT for total breast reconstruction as compared with IBR. Larger studies that include null measurements are required to further explore these noteworthy results of AFT.

Project description:ImportanceAutologous fat transfer (AFT or fat grafting) has become an invaluable tool for the correction of disfiguring deformities after breast cancer surgery. However, clinical and animal studies have shown conflicting results regarding its oncologic safety.ObjectiveTo determine whether exposure to AFT vs conventional breast reconstruction is associated with increased rates of cancer relapse in patients with breast cancer.Design, setting, and participantsThis matched cohort study involved retrospective medical record review to identify all patients in a local patient database receiving AFT between 2006 and 2014. Each AFT case was matched with a nonexposed control patient with similar baseline characteristics. The mean (SD) follow-up of patients receiving AFT was 9.3 (4.9) years including 5.0 (1.7) years following AFT. Control patients were followed up for a mean (SD) of 8.6 (1.8) years from the primary surgery. Patients were identified through the local patient database of the Tergooi Hospital in Hilversum, the Netherlands. A total of 287 patients with breast cancer (300 affected breasts) who received AFT for breast reconstruction after cancer were included in the intervention group. Each AFT case was matched with a respective control patient based on age, type of oncologic surgery, tumor invasiveness, and disease stage. In addition, individual AFT-control pairs were selected to have the same locoregional recurrence-free interval at baseline. Data were analyzed between 2016 and 2017.ExposuresReconstruction with AFT vs conventional breast reconstruction or none.Main outcomes and measuresPrimary end points were the cumulative incidences of oncologic events in AFT and control patients and their respective hazard ratios.ResultsOf the 587 total patients, all were women and the mean age was 48.1 years for the patients undergoing AFT and 49.4 years for the control patients. Eight locoregional recurrences were observed in the treatment group (287 patients) and 11 among the control group (300 patients), leading to an unadjusted hazard ratio of 0.63 (95% CI, 0.25-1.60; P = .33). No increased locoregional recurrence rates were seen in relevant subgroups based on the type of oncological surgery, tumor invasiveness, or pathological stage. In addition, no increased risks with AFT were detected with respect to distant recurrences or breast cancer-specific mortality.Conclusions and relevanceNo significant differences in the locoregional recurrence rates between the AFT and control groups were observed after 5 years of follow-up. These findings confirm the results of previous studies; therefore, clinical evidence suggesting that AFT is associated with increased risk for cancer relapse is still lacking.

Project description:Background Autologous fat transfer (AFT) is a minimally invasive technique that employs a patient’s own fat to correct disfiguring sequelae for breast reconstruction in postoperative breast cancer patients. However, the results of studies on this topic were controversial. In order to explore the effect of AFT on breast reconstruction after breast cancer surgery, we included cohort studies and conducted a meta-analysis. Methods A literature search was conducted using PubMed, Embase, Cochrane Library, and Web of Science databases for relevant studies published up to September 14, 2020. We identified the eligible studies based on the PICOS principles, populations (patients diagnosed with breast cancer), interventions (patients undergoing AFT after breast cancer surgery), controls (patients who did not receive AFT after breast cancer surgery), outcomes [local recurrence (LR) rate, regional recurrence (RRR) rate, locoregional recurrence (LRR) rate, distant metastasis rate, systemic recurrence (SR) rate, and total death rate], study design (cohort studies). The I2 statistic was conducted to estimate heterogeneity. Relative risks (RRs) with 95% confidence intervals (CIs) were presented to evaluate whether AFT compromises oncological safety in breast reconstruction. Funnel plots and Egger’s test were adopted to assess publication bias. Quality assessment for the included studies using the Newcastle-Ottawa Scale (NOS). Results Twenty-two cohort studies involving 9,971 postoperative patients with breast cancer were identified, with 3,622 receiving AFT being the experimental group, and 6,349 not receiving AFT in the control group. The overall quality of the included studies was rated as high. No significant differences in the rate of LR (RR: 0.916, 95% CI: 0.704–1.192), RRR (RR: 1.175, 95% CI: 0.773–1.787), LRR (RR: 0.788, 95% CI: 0.617–1.006), distant metastasis (RR: 1.133, 95% CI: 0.906–1.417), and total deaths (RR: 0.753, 95% CI: 0.539–1.051) were observed between the experimental group and control group (P>0.05). However, the AFT group had a lower rate of SR (RR: 0.671, 95% CI: 0.491–0.915, P=0.012). Conclusions The AFT group did not increase the rate of LR, RRR, LRR, distant metastasis, and total deaths in postoperative patients, which may indicate that AFT can be performed safely in breast reconstruction after excision of breast tumor.
