Background While obesity is thought to increase complication rates in general surgery procedures, its effect in mastectomy patients remains to be fully elucidated. We sought to determine if obesity is associated with a higher complication rate and length of stay after mastectomy, independent of clinicopathologic and treatment factors. Methods Medical records of breast cancer patients undergoing mastectomy at our institution between January 2010 and December 2017 were retrospectively reviewed. Patients were separated into obese (body mass index [BMI] ≥ 30) and nonobese (BMI < 30) categories and compared using nonparametric statistical analyses. Results Of 927 patients, 291 (31.2%) were obese. Obese patients had more complications (26.5% vs. 20.0%, P = 0.033) and a greater number of complications per patient ( P = 0.025) than nonobese patients. They were more likely to have infections (10.7% vs. 5.7%, P = .009), flap thrombosis/necrosis (5.5% vs. 2.4%, P = .018), and skin breakdown/wound complications (8.6% vs. 4.6%, P = .022). Additionally, obese patients had longer hospital length of stay (LOS; LOS > 2 days: 77.7% vs. 65.2%, P < .001). Controlling for potential confounders, obesity remained associated with a higher rate of thrombosis/necrosis of flap (odds ratio [OR] = 2.26; 95% confidence interval [CI] 1.01-5.08; P = .047) and LOS ≥ 2 days (OR = 1.82; 95% CI 1.23-2.69; P = .003). Conclusion Obese breast cancer patients undergoing mastectomy have more thrombosis/necrosis of flap and a longer hospital LOS than nonobese patients, regardless of other comorbidities and clinicopathologic/treatment factors.

Background Patient and tumor characteristics often coincide with obesity, potentially affecting treatment decision-making in obese breast cancer patients. Independent of all of these factors, however, it is unclear whether obesity itself impacts the decision to offer patients undergoing mastectomy breast reconstruction, postmastectomy radiation therapy (PMRT), or neoadjuvant chemotherapy. We sought to determine whether implicit bias against obese breast cancer patients undergoing mastectomy plays a role in their treatment. Methods Medical records of breast cancer patients undergoing mastectomy from January 2010 to April 2018 from a single institution were retrospectively reviewed, separated into obese (BMI ≥30) and nonobese (BMI <30) categories, and compared using nonparametric statistical analyses. Results Of 972 patients, 291 (31.2%) were obese. Obese patients were more likely to have node-positive, triple-negative breast cancers ( P = .026) and were also more likely to have other comorbidities such as a history of smoking ( P = .026), hypertension ( P < .001), and diabetes ( P < .001). Receipt of immediate reconstruction and contralateral prophylactic mastectomy did not vary between obese and nonobese patients. While obese patients were more likely to undergo neoadjuvant chemotherapy (26.5% vs. 18.1%, P = .004) and PMRT (33.0% vs. 23.4%, P = .003), this did not remain significant when controlling for comorbidities and clinicopathologic confounders. Conclusion Obese patients present with more aggressive tumors and often have concomitant comorbidities. Independent of these factors, however, differences in the treatment of patients undergoing mastectomy do not seem to be affected by an implicit bias against obese patients.

Response To Neoadjuvant Chemotherapy

Purpose To understand the mechanism through which obesity in breast cancer patients is associated with poorer outcome, we evaluated body mass index (BMI) and response to neoadjuvant chemotherapy (NC) in women with operable breast cancer. Patients and Methods From May 1990 to July 2004, 1,169 patients were diagnosed with invasive breast cancer at M. D. Anderson Cancer Center and received NC before surgery. Patients were categorized as obese (BMI ≥ 30 kg/m2), overweight (BMI of 25 to < 30 kg/m2), or normal/underweight (BMI < 25 kg/m2). Logistic regression was used to examine associations between BMI and pathologic complete response (pCR). Breast cancer–specific, progression-free, and overall survival times were examined using the Kaplan-Meier method and Cox proportional hazards regression analysis. All statistical tests were two-sided. Results Median age was 50 years; 30% of patients were obese, 32% were overweight, and 38% were normal or underweight. In multivariate analysis, there was no significant difference in pCR for obese compared with normal weight patients (odds ratio [OR] = 0.78; 95% CI, 0.49 to 1.26). Overweight and the combination of overweight and obese patients were significantly less likely to have a pCR (OR = 0.59; 95% CI, 0.37 to 0.95; and OR = 0.67; 95% CI, 0.45 to 0.99, respectively). Obese patients were more likely to have hormone-negative tumors (P < .01), stage III tumors (P < .01), and worse overall survival (P = .006) at a median follow-up time of 4.1 years. Conclusion Higher BMI was associated with worse pCR to NC. In addition, its association with worse overall survival suggests that greater attention should be focused on this risk factor to optimize the care of breast cancer patients.

Introduction. Literature shows platelet-rich plasma (PRP) to improve overall outcomes in orthopedics, dermatology, ophthalmology, gynecology, and plastic surgery. Data on oncological patients is very limited. Only one publication is available on PRP in breast cancer patients. This work evaluated PRP in sentinel node biopsy procedures for breast cancer patients in terms of complication rates and oncological short-term follow-up. Methods. The evaluated PRP was ACP®, i.e., autologous conditioned plasma by Arthrex®. Between 2015 and 2018, 163 patients were offered to receive an ACP®/PRP injection in their lymph node biopsy site. Recruitment resulted in an approximate one-to-one ratio for analysis. Endpoints were major (revision) and minor (seroma, hematoma, and infection) complications rates as well as distant metastases, local recurrence, and overall survival. Median follow-up was 30 months. Results. Complication rates and oncological follow-up showed PRP to be applicable to use in a sentinel node biopsy scenario in breast cancer patients. There were 0 revisions in the ACP®/PRP group and 1.2% revisions in the control group (not significant). Oncological follow-up showed zero (0) distant metastases and local recurrences as well as a 100% 30-month overall survival. Conclusions. This is the first analysis of ACP®/PRP used in breast cancer patients in a sentinel node biopsy setting worldwide. PRP does not seem to increase rates of local recurrence within this 30-month follow-up time frame. Also, trend towards decreasing complication rates could be shown.

AbstractThe objective was to report the effect of obesity, utilizing a body mass index (BMI) threshold of 35 kg/m2, on outcomes and complications of multiple ligament knee injury (MLKI). It was hypothesized that obese patients would have longer intraoperative times and hospital length of stay, greater estimated blood loss, and higher rates of wound infection requiring irrigation and debridement (I&D) and revision ligament surgery. A retrospective review was performed on 143 individuals who underwent surgery for an MLKI between 2011 and 2018 at a single academic center. Patients were included if there was a plan for potential surgical repair/reconstruction of two or more ligaments. Patients with prior surgery to the affected knee or intra-articular fracture requiring reduction and fixation were excluded. Comparisons between obese and nonobese patients were made using two-sample t-test and either chi-square or Fisher's exact test for continuous and categorical variables, respectively. Significance was set at p < 0.05. Of 108 patients meeting inclusion criteria, 83 had BMI < 35 kg/m2 and 25 had BMI ≥ 35 kg/m2. Obese patients sustained higher rates of MLKI due to ultralow velocity mechanisms (28.0 vs. 1.2%; p = 0.0001) and higher rates of concomitant lateral meniscus injury (48.0 vs. 25.3%; p = 0.04). Among patients undergoing single-staged surgery, obese patients had significantly longer duration of surgery (219.8 vs. 178.6 minutes; p = 0.02) and more wound infections requiring I&D (20.0 vs. 4.8%; p = 0.03). In contrast, nonobese patients had higher rates of arthrofibrosis requiring manipulation under anesthesia and/or arthrolysis (25.3 vs. 0%; p = 0.003). Obese patients undergoing surgery of an MLKI have longer operative times, greater rates of wound infection requiring I&D, and lower rates of arthrofibrosis. Surgeons may consider these results when counseling patients on their postoperative course and risk for complications. Future research might focus on strategies to reduce complication rates in obese patients with MLKI. This is a Level III, retrospective comparative study.

The Impact

Obesity has long been considered a risk factor for surgery. The purpose of this study was to evaluate the impact of obesity on outcomes after appendectomy. A retrospective study was performed using discharge abstract data obtained from patients with documented body mass index (BMI) undergoing appendectomy for appendicitis (n = 2919). Complications and length of stay for different BMI categories were compared. Obese patients (BMI > 30 kg/m2) had similar rates of perforation (20%) and were as likely to undergo a laparoscopic approach (85%) as nonobese patients. On multivariable and univariate analysis, no significant differences were observed when comparing obese and nonobese patients for the outcomes of length of stay, infectious complications, and need for readmission. On multivariate analysis, laparoscopy predicted lower complication rates and decreased length of stay. In this study, obesity did not significantly impact rates of perforation, operative approach, length of stay, infectious complications, or readmission.
