Improving the Breast Surgeon's Ergonomic Workload for Nipple-Sparing Mastectomies Using Exercise and Operating Room Positioning Protocol.

BACKGROUND: The objective of this study was to examine whether an exercise program and standardized operating room positioning protocol (EOPP) would improve surgeon muscle workload and/or surgeon perception of mental/physical workload for nipple-sparing mastectomy (NSM). METHODS: This prospective study analyzed muscle workload by EMG of four surgeons performing NSM before and after an EOPP. Surveys were administered assessing surgeon perception of mental/physical workload. EMG data were analyzed using repeated-measures ANOVA, controlling for surgeon, first assistant, duration and difficulty of procedure, left or right side, and sequence of the procedure. RESULTS: A total of 56 NSM cases performed by 3 surgeons were analyzed. One surgeon was excluded because of muscle injury and undergoing active physical therapy during the study period. After implementation of the EOPP, the left (P = 0.005) and right (P = 0.020) upper trapezii muscles had a significant decrease in overall ergonomic workload but there was no significant change in overall ergonomic workload for the bilateral cervical erector spinae, anterior deltoid, and lumbar erector spinae muscle groups. When analyzing muscle group exertion by surgeon, there was significant variability in all muscles except the left cervical erector spinae. Following the EOPP, surgeons reported that the procedures were more physically (P = 0.01) and mentally (P = 0.002) demanding and visualization (P = 0.04) was worse. The breast laterality and sequence did not affect muscle exertion. CONCLUSIONS: An EOPP decreased the overall ergonomic workload of one muscle group for surgeons performing NSM but did not impact surgeon perception of mental/physical workload. Further investigation is needed to improve surgeon ergonomics.

Patients Undergoing Bilateral Mastectomy and Breast-Conserving Surgery Have the Lowest Levels of Regret: The WhySurg Study.

BACKGROUND: The recent data on decision regret of patients undergoing breast cancer surgery are sparse. METHODS: An electronic cross-sectional survey was distributed to Love Research Army volunteers ages 18-70 years who underwent breast cancer surgery from 2009 to 2020. Decision regret scores were compared among patients who underwent bilateral mastectomy (BM), unilateral mastectomy (UM), breast-conserving surgery (BCS), and BCS first (BCS followed by re-excision or mastectomy) and between procedures during different time periods. Multivariable logistic regression, adjusted for patient and tumor factors, was used to determine whether surgery type was associated with a regret score in the highest quartile range. RESULTS: The survey was completed by 2148 women, 1525 (71.0%) of whom reported their surgery choice and answered all questions on the regret scale. The mean age of the participants was 50 years, and the median year of surgery was 2014. The median decision regret score for all the patients was 5 (interquartile range [IQR], 0-20) on a 100-point scale. The regret score of 342 participants (22.4%) was 25 or higher (BCS, 20.2%; BCS first, 31.9%; UM, 30.8%; BM, 15.4%; p < 0.001). In the multivariable analysis, BM was associated with less regret than UM (odds ratio [OR], 0.40 (range, 0.27-0.58); p < 0.001), BCS (OR, 0.56 (range, 0.38-0.83; p = 0.003), or BCS first (OR, 0.32; range, 0.21-0.49; p < 0.001). During the three periods analyzed (2009-2012, 2013-2016, and 2017-2020), the BM and BCS patients had the lowest regret scores of all the surgical types. CONCLUSIONS: Decision regret was low among the patients undergoing breast cancer surgery but lowest among the BM patients after adjustment for clinical and tumor factors including complications.

Predictors of survival in patients with disease recurrence after radical nephroureterectomy.

OBJECTIVES: To evaluate the prognostic value of the Bajorin criteria in a multi-institutional cohort of patients with disease recurrence after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). To investigate whether clinical, pathological and/or biological factors at time of disease recurrence are also associated with cancer-specific outcomes in these patients. PATIENTS AND METHODS: We identified 242 patients with disease recurrence after RNU for UTUC from 11 centres. With regard to the Bajorin criteria, patients were categorized into three groups based on two risk factors: Karnofsky performance status <80% and the presence of visceral metastasis. Assessed variables included pathological characteristics, time to disease recurrence, age-adjusted Charlson comorbidity index (ACCI), American Society of Anesthesiologists (ASA) score, and laboratory tests at time of disease recurrence. RESULTS: Overall, 185 patients died from their disease; the median survival was 9 months. The survival rates at 1 year were 53, 33, and 39% for patients with no (n = 18), one (n = 109) and two (n = 115) risk factors, respectively, with no significant difference between the groups. In univariable analyses, higher pT-stage, tumour necrosis, non-administered salvage chemotherapy, higher ACCI score, higher ASA score, lower albumin level and higher white blood cell count were significantly associated with a shorter time to cancer-specific mortality. CONCLUSIONS: We confirmed the poor yet variable outcomes of patients with disease recurrence after RNU. While the Bajorin criteria seem to have limited prognostic value in this specific cohort, we found several other clinical variables to be associated with worse cancer-specific mortality. If validated, these factors should be taken into consideration for clinical trial design.

Critical analysis of 30 day complications following radical nephroureterectomy for upper tract urothelial carcinoma.

INTRODUCTION: Patients with upper tract urothelial carcinoma (UTUC) are often elderly and comorbid owing to associated risk factors for developing this malignancy. Perioperative complications may be significant in such a surgical population. We define the incidence and risk factors associated with perioperative complications occurring within 30 days of radical nephroureterectomy (RNU). MATERIALS AND METHODS: Medical records of 92 consecutive patients undergoing RNU were reviewed. Complications occurring within 30 days of surgery were graded using the modified Clavien-Dindo classification. The number, severity, and type of complications were recorded. Minor complications were classified as Clavien II or less, while major complications were Grade III or greater. Univariate and multivariate analyses determined variables associated with complications. RESULTS: Fifty-seven men and 35 women with a median age of 70 years were included. Three-quarters of the cohort underwent a minimally invasive RNU and 45% had a regional lymph node dissection. Final pathology noted that 53% had muscle-invasive and 70% had high grade UTUC. Overall, 35 patients (38%) experienced complications within 30 days of RNU including 11 (12%) with major complications. Ten patients (11%) had multiple complications. Hematologic, gastrointestinal, and infectious etiologies comprised over 75% of complications. On univariate analysis, patient age, ECOG performance status, surgical approach, non-organ confined disease, and cardiac history were associated with complications. In a multivariate model including these variables, only ECOG ≥ 2 (OR 3.9, 95% CI 1.6-7.4, p < 0.001) was independently associated with post-RNU complications. CONCLUSION: Almost 40% of patients in this cohort experienced a perioperative complication after RNU. One-third of complications were Clavien III or greater. Poor performance status conferred a four-fold greater risk of a perioperative complication. Such knowledge may guide patient counseling and surgical expectations for the postoperative period.

Impact of Surgical Delay on Tumor Upstaging and Outcomes in Estrogen Receptor-Negative Ductal Carcinoma in Situ Patients.

BACKGROUND: The delay of elective surgeries by the coronavirus 2019 (COVID-19) pandemic prompted concern among surgeons to delay estrogen receptor (ER)-negative ductal carcinoma in situ (DCIS) for fear of missing an ER-negative invasive cancer and compromising survival of patients. STUDY DESIGN: Female patients ≥40 years old diagnosed with ER-negative DCIS from 2004 to 2017 were examined from the National Cancer Database. Multivariable logistic regression, adjusting for patient and tumor factors, was used to determine factors associated with tumor upstage. Multivariable Cox proportional hazards modeling was used to determine if surgical delay impacted overall survival of ER-negative DCIS patients that were upstaged to invasive disease. RESULTS: There were 219,731 patients with DCIS of which 24,338 (11.1%) had tumor upstage. Of these patients, 5,675 (16.2%) of ER-negative and 18,663 (10.1%) of ER-positive DCIS patients were upstaged (p ≤ 0.001). From 2004 to 2017, ER-negative DCIS upstage rates increased from 12.9% to 18.9%. Independent factors associated with tumor upstage were younger age (odds ratio [OR] 0.75 [95% CI 0.69 to 0.81]) and Black race (OR 1.34 [95% CI 1.22 to 1.46]). Compared with patients with ≤30 days between biopsy and surgery, patients with a 31- to 60-day interval (OR 1.13 [95% CI 1.05 to 1.20]) and a >60-day interval (OR 1.12 [95% CI 1.02 to 1.23]) had an increased rate of tumor upstage. Among ER-negative DCIS patients whose tumors were upstaged to invasive disease, Cox proportional hazard regression modeling showed no association between the number of days between biopsy and surgery and overall survival. CONCLUSIONS: Delays in surgery were associated with higher tumor upstage rates but not with worse overall survival.
