Reconstructive outcome analysis of the impact of neoadjuvant chemotherapy on immediate breast reconstruction: a retrospective cross-sectional study.

ABSTRACT:

Background

Neoadjuvant chemotherapy (NACT) was initially applied to locally advanced breast cancer to convert advanced lesions to an operable status. Currently, its application has been expanded to enhance overall oncological results, especially in patients with triple-negative or HER-2-positive breast cancer. With more NACT being applied, the role and impact of this approach on breast reconstruction needs to be determined. This study aimed to perform a complete reconstructive outcome analysis of patients receiving NACT who underwent immediate breast reconstruction.

Methods

A retrospective review of a single reconstructive surgeon's immediate breast reconstructions performed from July 2008 to December 2018 was undertaken. The results were stratified by the use of NACT. Patient demographics, delivery of NACT, adjuvant treatment, incidence of surgical complications, and postoperative photographs were analyzed.

Results

A total of 269 patients were included. The mean follow-up was 46.3 months. Forty-six out of 269 patients received NACT and were included in the NACT group. The other patients were included in the non-NACT group. When implant-based reconstruction was planned, the NACT group had a higher rate of two-stage tissue expander-implant reconstruction than direct-to-implant reconstruction (p < 0.001). The requirement for postmastectomy radiotherapy was higher in the NACT group (p < 0.001). The surgical complication rates were similar between groups after adjusting for confounding factors. The objective aesthetic outcomes assessed by 6 plastic surgeons were also similar between groups.

Conclusions

Immediate breast reconstruction is a safe and reliable procedure, with an acceptable reconstructive complication rate and satisfactory aesthetic outcomes, for patients treated with NACT.

Project description:BackgroundThe impact of neoadjuvant chemotherapy (NACT) on surgical outcomes following immediate breast reconstruction (IBR) remains unclear. While it is generally considered safe practice to perform an IBR post NACT, reported complication rates in published data are highly variable with the majority of studies including fewer than 50 patients in the NACT and IBR arm. To evaluate this further, we conducted a systematic review and meta-analysis on the effect of NACT on autologous and implant based immediate breast reconstructions. We aimed to assess for differences in the post-operative course following IBR between patients who received NACT with those who did not.MethodsPubMed, EMBASE, and Cochrane Library were searched from 1995 to Sept 2, 2020 to identify articles that assessed the impact of NACT on IBR. All included studies assessed outcomes following IBR. Only studies comparing reconstructed patients receiving NACT to a control group of women who did not receive NACT were included. Unadjusted relative risk of outcomes between patients who received or did not receive NACT were synthesized using a fixed-effect meta-analysis. The evidence was assessed using the Newcastle Ottawa Scale scores and GRADE. Primary effect measures were risk ratios (RRs) with 95% confidence intervals.ResultsA total 17 studies comprising 3249 patients were included in the meta-analyses. Overall, NACT did not increase the risk of complications after immediate breast reconstructions (risk ratio [RR]: 0.91, 95% CI 0.74 to 1.11, p = 0.34). There was a moderate, but not significant, increase in flap loss following NACT compared with controls (RR: 1.23, 95% CI 0.70 to 2.18, p = 0.47; I2 = 0%). Most notably, there was a statistically significant increase in implant/expander loss after NACT (RR: 1.54, 95% CI 1.04 to 2.29, p = 0.03; I2 = 34%). NACT was not shown to significantly increase the incidence of hematomas, seromas or wound complications, or result in a significant delay to commencing adjuvant therapy (RR: 1.59, 95% CI 0.66 to 3.87, p = 0.30).ConclusionImmediate breast reconstruction after NACT is a safe procedure with an acceptable post-operative complication profile. It may result in a slight increase in implant loss rates, but it does not delay commencing adjuvant therapy.

Project description:BackgroundWith advancements in and the evolution of the medical field, several methods and surgical techniques have been developed for breast reconstruction after mastectomy. Generally, we can categorize these strategies into two broad groups: autologous reconstruction and implant-based reconstruction. This study aimed to analyze the satisfaction rate between these groups, considering age, timing of breast reconstruction, body mass index (BMI), major complications, and the need for radiotherapy or chemotherapy.Materials and methodsAll the patients who underwent a mastectomy and subsequent breast reconstruction surgery at our institution between August 1, 2013, and August 31, 2017, were invited to complete a BREAST-Q questionnaire. To compare the quality of life and complication rate between the autologous and implant-based reconstruction groups, data were collected from specific patients. All participants completed the Arabic version of the postoperative reconstruction module.ResultsAmong 61 patients, 43 (70.5%) completed the two domains of the BREAST-Q questionnaire, about the satisfaction with the implanted breast and satisfaction with the surgical outcome. These patients were divided into two groups: autologous (n = 21) and implant-based (n = 22) groups. The mean score of satisfaction with the implanted breast was 43.5 for the autologous group and 39.6 for the implant-based group. For the surgical outcome, the scores for the autologous and implant-based groups were 45.4 and 56.0, respectively. However, there was neither a statistical significance in the satisfaction with the implanted breast nor the surgical outcome between the two groups.ConclusionAlthough there are many different surgical techniques to reconstruct a breast after mastectomy, there is still no specific surgical method that is perfect or well-suited for all patients undergoing breast reconstruction surgery. In our study, we found that there was no significant difference in satisfaction between the ABR and IBR group.

Project description:Neoadjuvant chemotherapy (NC) is increasingly being used in patients with breast cancer, and evidence-based reports related to its independent effects on morbidity after mastectomy with immediate breast reconstruction are limited.To determine the effect of NC on 30-day postoperative morbidity in women undergoing mastectomy with or without immediate breast reconstruction.All women undergoing mastectomy with or without immediate breast reconstruction from January 1, 2005, through December 31, 2011, at university and private hospitals internationally were analyzed using the American College of Surgeons National Surgical Quality Improvement Program 2005-2011 databases. Patients who received NC were compared with those without a history of NC to estimate the relative odds of 30-day postoperative overall, systemic, and surgical site morbidity using model-wise multivariable logistic regression.Neoadjuvant chemotherapy.Thirty-day postoperative morbidity (overall, systemic, and surgical site).Of 85,851 women, 66,593 (77.6%) underwent mastectomy without breast reconstruction, with 2876 (4.3%) receiving NC; 7893 patients were excluded because of missing exposure data. The immediate breast reconstruction population included 19,258 patients (22.4%), with 820 (4.3%) receiving NC. After univariable analysis, NC was associated with a 20% lower odds of overall morbidity in the group undergoing mastectomy without breast reconstruction (odds ratio [OR], 0.80; 95% CI, 0.71-0.91) but had no significant effect in the immediate breast reconstruction group (OR, 0.98; 95% CI, 0.79-1.23). After adjustment for confounding, NC was independently associated with lower overall morbidity in the group undergoing mastectomy without breast reconstruction (OR, 0.61; 95% CI, 0.51-0.73) and the immediate tissue expander reconstruction subgroup (OR, 0.49; 95% CI, 0.30-0.84). Neoadjuvant chemotherapy was associated with decreased odds of systemic morbidity in 4 different populations: complete sample (OR, 0.59; 95% CI, 0.49-0.71), mastectomy without breast reconstruction (OR, 0.59; 95% CI, 0.48-0.72), any immediate breast reconstruction (OR, 0.57; 95% CI, 0.37-0.88), and the tissue expander subgroup (OR, 0.41; 95% CI, 0.23-0.72).Our study supports the safety of NC in women undergoing mastectomy with or without immediate breast reconstruction. Neoadjuvant chemotherapy is associated with lower overall morbidity in the patients undergoing mastectomy without breast reconstruction and in those undergoing tissue expander breast reconstruction. In addition, the odds of systemic morbidity were decreased in patients undergoing mastectomy with and without immediate breast reconstruction. The mechanisms behind the protective association of NC remain unknown and warrant further investigation.
