Abstract
INTRODUCTION Surgical resection is the gold standard for early-stage breast cancer. Positive surgical margins are associated with poor outcome. Endocrine therapy (ET) is recommended as primary systemic treatment for hormone receptor positive (HR+) breast cancer after surgery. We hypothesized that chemoenocrine therapy (CET) would not be associated with improved survival relative to ET for patients with positive margins. MATERIALS AND METHODS The National Cancer Database was queried for pathologic stage I HR + HER2-breast cancer patients treated with partial mastectomy and adjuvant whole-breast irradiation between 2004 and 2017. The adjuvant treatment approaches to positive surgical margins were investigated and compared. Overall survival was compared between systemic treatment groups using multivariable cox proportional hazards regression. RESULTS Among 228,453 patients, a positive surgical margin (microscopic residual disease, R1) was identified in 3561 (1.6%) patients. Compared with complete resections, positive margin was associated with inferior overall survival (hazard ratio [HR] = 1.276, P = 0.003). Among the R1 patients, 78.7% received ET only, 11.7% received CET, 1.2% received chemotherapy only, and 8.5% received no systemic therapy. After controlling for patient, facility, and tumor characteristics, ET provided greatest survival benefit (relative to no therapy, HR = 0.378, P < 0.001) followed by CET (HR = 0.446, P = 0.020). Compared with ET alone, CET is not associated with additional overall survival benefit (HR = 1.179, P = 0.595). CONCLUSIONS CET appeared not to be associated with an improved overall survival in early stage HR + HER2-breast cancer with microscopic residual disease relative to ET. Positive surgical margins therefore are probably not a relevant clinical factor for adjuvant chemotherapy decision-making.

Abstract
BackgroundSurgical stabilization of rib fractures (SSRF) is performed on only a small subset of patients who meet guideline-recommended indications for surgery. Although previous studies show that provider specialization was associated with SSRF procedural competency, little is known about the impact of provider specialization on SSRF performance frequency. We hypothesize that provider specialization would impact performance of SSRF.MethodsThe Premier Hospital Database was used to identify adult patients with rib fractures from 2015 and 2019. The outcome of interest was performance of SSRF, defined using International Classification of Diseases—10th Revision Procedure Coding System coding. Patients were categorized as receiving their procedures from a thoracic, general surgeon, or orthopedic surgeon. Patients with missing or other provider types were excluded. Multivariate modeling was performed to evaluate the effect of surgical specialization on outcomes of SSRF. Given a priori assumptions that trauma centers may have different practice patterns, a subgroup analysis was performed excluding patients with ‘trauma center’ admissions.ResultsAmong 39 733 patients admitted with rib fractures, 2865 (7.2%) received SSRF. Trauma center admission represented a minority (1034, 36%) of SSRF procedures relative to other admission types (1831, 64%, p=0.15). In a multivariable analysis, thoracic (OR 6.94, 95% CI 5.94–8.11) and orthopedic provider (OR 2.60, 95% CI 2.16–3.14) types were significantly more likely to perform SSRF. In further analyses of trauma center admissions versus non-trauma center admissions, this pattern of SSRF performance was found at non-trauma centers.ConclusionThe majority of SSRF procedures in the USA are being performed by general surgeons and at non-trauma centers. ‘Subspecialty’ providers in orthopedics and thoracic surgery are performing fewer total SSRF interventions, but are more likely to perform SSRF, especially at non-trauma centers. Provider specialization as a barrier to SSRF may be related to competence in the SSRF procedures and requires further study.TypeTherapeutic/care management.Level of evidenceIV

Abstract
INTRODUCTION Although randomized trials demonstrate a benefit to surgical stabilization of rib fractures (SSRF), SSRF is rarely performed. We hypothesized older patients were less likely to receive SSRF nationally. METHODS The 2016 National Inpatient Sample was used to identify adults with flail chest. Comorbidities and receipt of SSRF were categorized by ICD-10 code. Univariable testing and Multivariable regression were performed to determine the association of demographic characteristics and comorbidities to receipt of SSRF. RESULTS 1021 patients with flail chest were identified, including 244 (23.9%) who received SSRF. Patients ≥70 years were less likely to receive SSRF. (<70 yrs 201/774 [26.0%] vs ≥70 43/247 [17.4%], P = .006) and had higher risk of death (<70 yrs 39/774 [5.0%] vs ≥70 33/247 [13.4%], P < .001) In multivariable modeling, only age ≥70 years was associated with SSRF (OR .591, P = .005). CONCLUSION Despite guideline-based support of SSRF in flail chest, SSRF is performed in <25% of patients. Age ≥70 years is associated with lower rate of SSRF and higher risk of death. Future study should examine barriers to SSRF in older patients.

Modeling the COVID Pandemic: Do Delays in Surgery Justify Using Stereotactic Radiation to Treat Low-Risk Early Stage Non-Small Cell Lung Cancer? J Surg Res 2023; 283:532-539. [PMID: 36436290 PMCID: PMC9686123 DOI: 10.1016/j.jss.2022.10.081] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 08/02/2022] [Accepted: 10/08/2022] [Indexed: 11/25/2022]
Abstract
INTRODUCTION It was suggested that stereotactic radiation (SBRT) is an "alternative if no surgical capacity is available" for non-small cell lung cancer (NSCLC) care during the COVID-19 pandemic. The purpose of this study was to compare the oncologic outcomes of delayed surgical resection and early SBRT among operable patients with early stage lung cancer. METHODS The National Cancer Database was queried for patients with cT1aN0M0 NSCLC who underwent surgery or SBRT (2010-2016) with no comorbidity. Patients with any comorbidities or age >80 were excluded. The outcome of interest was overall survival. Delays in surgical care were modeled using different times from diagnosis to surgery. A 1:1 propensity match was performed and survival was analyzed using multivariable Cox regression. RESULTS Of 6720 healthy cT1aN0M0 NSCLC patients, 6008 (89.4%) received surgery and 712 (10.6%) received SBRT. Among surgery patients, time to surgery >30 d was associated with inferior survival (HR > 1.4, P ≤ 0.013) compared with patients receiving surgery ≤14 d. Relative to SBRT, surgery demonstrated superior survival at all time points evaluated: 0-30 d, 31-60 d, 61-90 d, and >90 d (all P < 0.001). Among a propensity-matched cohort of 256 pairs of patients, delayed surgery (>90 d) remained association with better overall survival relative to early SBRT (5-year survival 76.9% versus 32.3%, HR = 0.266, P < 0.001). CONCLUSIONS Although longer time to surgery is associated with inferior survival among surgery patients, delayed surgery is superior to early SBRT. Surgical resection should remain the standard of care to treat operable early stage lung cancer despite delays imposed by the COVID-19 pandemic.

Abstract
INTRODUCTION Emergency General Surgery (EGS) conditions in older patients constitutes a substantial public health burden due to high morbidity and mortality. We sought to utilize a supervised machine learning method to determine combinations of factors with the greatest influence on long-term survival in older EGS patients. METHODS We identified community dwelling participants admitted for EGS conditions from the Medicare Current Beneficiary Survey linked with claims (1992-2013). We categorized three binary domains of multimorbidity: chronic conditions, functional limitations, and geriatric syndromes (such as vision or hearing impairment, falls, incontinence). We also collected EGS disease type, age, and sex. We created a classification and regression tree (CART) model to identify groups of variables associated with our outcome of interest, three-year survival. We then performed Cox proportional hazards analysis to determine hazard ratios for each group with the lowest risk group as reference. RESULTS We identified 1960 patients (median age 79 [interquartile range [IQR]: 73, 85], 59.5% female). The CART model identified the presence of functional limitations as the primary splitting variable. The lowest risk group were patient aged ≤81 y with biliopancreatic disease and without functional limitations. The highest risk group was men aged ≥75 y with functional limitations (hazard ratio [HR] 11.09 (95% confidence interval [CI] 5.91-20.83)). Notably absent from the CART model were chronic conditions and geriatric syndromes. CONCLUSIONS More than the presence of chronic conditions or geriatric syndromes, functional limitations are an important predictor of long-term survival and must be included in presurgical assessment.

Abstract
BACKGROUND Esophagectomy carries a high risk of morbidity and mortality. The most common indication for esophagectomy is esophageal cancer, with fewer than 5% of esophagectomies performed for benign disease. We hypothesized that esophagectomy for benign disease is associated with a higher risk of operative and postoperative complications. METHODS A retrospective study of The Society of Thoracic Surgeons database was performed to identify all patients who had an esophagectomy from 2010 to 2018. Patients who had an emergent or palliative esophagectomy were excluded. Patients were compared based on the indication for operation, malignant vs benign disease. A 1:1 propensity score matching of The Society of Thoracic Surgeons risk factors was performed and outcomes compared between the matched cohorts. RESULTS Of 16,392 patients, 14,871 (91%) had malignant disease and 1521 (9%) had benign disease that met inclusion criteria. Patients with malignant disease were older (P < .001), more likely to be male (83% vs 56%, P < .001), and had more comorbidities (P < .001). There were 1362 propensity-matched pairs. Malignant esophagectomies were more likely to be performed with a minimally invasive vs an open approach (P < .001). Benign operations had more intraoperative blood transfusions (P < .001). Patients undergoing esophagectomy for benign disease had more prolonged intubations (P = .02) and postoperative blood transfusions (P = .001). Benign disease had more major morbidities (P = .001) but similar postoperative mortality (P = .62). CONCLUSIONS Esophagectomy for benign disease is associated with worse perioperative morbidity compared with esophagectomy for malignant disease. Given these findings patients should be counseled on expected outcomes, and this variable should be considered for inclusion in the composite score for risk assessment.

Abstract
Adenocarcinoma and squamous cell esophageal cancers have been extensively studied in the literature. Esophageal neuroendocrine (NET)/carcinoid tumors are less commonly studied and have only been described in small series. The purpose of this study was to describe the demographics and natural history of esophageal NETs, as well as optimal treatments. We hypothesized that surgical resection would be the best treatment of esophageal NETs. The National Cancer Database was used to identify adult patients with esophageal or gastroesophageal junction (GEJ) cancer from 2004 to 2018. Patients were characterized as carcinoid/NET, adenocarcinoma, or squamous cell cancer. Clinical and demographic characteristics were compared between the histology groups. The primary outcome was overall survival, which was assessed by multivariable Cox analysis. Multivariable Cox analysis was also used to analyze factors associated with survival among NET patients who underwent surgery. Among 206,321 patients with esophageal cancer, 1,563 were NETs (<0.01%). Relative to the other two histologies, NETs were associated with younger age, female sex, and advanced clinical stage at diagnosis. Multivariate analysis suggested that NETs were less likely to be treated with surgical resection (OR 0.51, P < 0.001). Nonetheless, surgical resection was associated with improved survival (HR 0.64, P = 0.003). Among patients with NETs who received surgery, neoadjuvant therapy was associated with improved overall survival (HR 0.38, P = 0.013). NET of the esophagus presents with more advanced disease than other common histologies. Among patients with nonmetastatic cancer, surgical resection appears to be the best treatment. Neoadjuvant systemic therapy may offer survival benefit, but future studies are necessary.

Abstract
Objective Chondrosarcoma is the most common primary malignant chest wall tumor and is historically associated with poor prognosis. Recommendations regarding surgical excision are on the basis of small, single-institution studies. We used a large national database to assess outcomes of surgery for chest wall chondrosarcoma (CWC) hypothesizing that surgical excision remains standard of care. Methods The National Cancer Databases for bone and soft tissue were merged to identify patients with chondrosarcoma from 2004 to 2018. Clinical and demographic characteristics of CWC were compared with chondrosarcoma from other sites. The primary outcome was overall survival described using Kaplan-Meier estimate. Univariable and multivariable Cox analysis was used to determine risk factors for poor survival among CWC patients who underwent surgery. Multivariable analysis of predictors of margin status was performed because of worse prognosis associated with positive margins. Results Among 11,925 patients with chondrosarcoma, 1934 (16.2%) had a CWC. Relative to other sites, CWC was associated with older age, male sex, White race, surgical resection, and care at a nonacademic institution. CWC was associated with 1-, 3-, 5-, and 10-year survival of 91.5%, 82.0%, 75.5%, and 62.7%, respectively. In univariable analysis, survival was associated with surgery (hazard ratio, 0.02; P < .001) and adversely affected by positive margins (hazard ratio, 2.66; P < .001). Multivariable analysis showed larger tumor size was independently associated with increased risk for positive margins (odds ratio, 1.04; 95% CI, 1.011-1.075). Conclusions CWC represents a different cohort of patients relative to chondrosarcoma from other sites. Surgical excision remains the optimal treatment, and positive margins are associated with poor prognosis.

Abstract
Background The RxPONDER trial found that among breast cancer patients with estrogen receptor positive (ER+) breast cancer, 1-3 positive axillary nodes, and a recurrence score of ≤25, only pre-menopausal women benefitted from adjuvant chemoendocrine therapy; postmenopausal women with similar characteristic did not benefit from adjuvant chemotherapy. We aimed to replicate the RxPonder trial using a larger patient cohort with real world data to determine whether a RS threshold existed where adjuvant chemotherapy was beneficial regardless of age. Methods The National Cancer Database (NCDB) was queried for women with ER+, human epidermal growth factor receptor 2 (HER2) negative breast cancer, 1-3 positive axillary nodes, and RS ≤25 who received endocrine (ET) only or chemo-endocrine therapy (CET). Cox regression interaction was explored between CET and age as a surrogate for menopausal status. Results The final analytic cohort included 28,427 eligible women: 7,487 (26.3%) received adjuvant CET and 20,940 (73.7%) ET. In the entire cohort, RS had a normal distribution, with a median score of 14. After correcting for demographic and clinical variables, a threshold effect was observed with RS >20 being associated with a significantly inferior overall survival (OS) (P value range: < 0.001-0.019). In women with RS of 20-25, CET was associated with a significant improvement in OS compared to ET alone, regardless of age (age <=50: HR = 0.334, P=0.002; age>50: HR=0.521, P=0.019). Conclusion Among women with ER+/HER2- breast cancer with 1-3 positive nodes, and a RS of 20-25-in contrast to the RxPONDER trial-we observed that CET was associated with an OS benefit in women regardless of age.

Abstract
The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) remains the largest and most robust thoracic surgical database in the world. Participating sites receive risk-adjusted performance reports for benchmarking and quality improvement initiatives. The GTSD also provides several mechanisms for high-quality clinical research using data from 274 participant sites and 781,000 procedures since its inception in 2002. Participant sites are audited at random annually for completeness and accuracy. Over the last year and a half, the GTSD Task Force continued to refine the data collection process, implementing an updated data collection form in July 2021, ensuring high data fidelity while minimizing data entry burden. In addition, the STS Workforce on National Databases has supported a robust GTSD-based research program, which led to eight scholarly publications in 2021. This report provides an update on volume trends, outcomes, and database initiatives as well as a summary of research productivity resulting from the GTSD over the preceding year.

Abstract
Background: Necrotizing soft tissue infections (NSTIs) are rapidly progressive infections with high mortality and complication rates. The incidence of NSTIs has been increasing steadily whereas mortality has decreased; survivors have a high risk of re-hospitalization. We hypothesized that re-admission to the index hospital where the first admission occurred would be associated with better clinical outcomes compared with re-admission to a non-index hospital. Patients and Methods: We identified patients from the 2017 Nationwide Readmissions Database with an index admission for NSTIs and examined all-cause re-admissions within 90 days of discharge. We noted whether re-admission occurred at the index or a non-index hospital. Survey-weighted logistic regression identified factors associated with death at the first re-admission and re-admission to index hospital. We also compared patient outcomes between patients admitted to index versus non-index hospitals. Results: We identified 27,051 NSTI survivors, of whom 6,954 (25.7%) had an unplanned re-admission within 90 days. A large proportion of re-admission occurred at non-index hospitals (28.3%; n = 1,966). Factors associated with non-index re-admission included prolonged index length of stay, discharge to short-term hospital, and leaving against medical advice. Patients re-admitted to index hospitals had a lower mortality rate (4.7% vs. 6.7%; p = 0.003), lower admission costs (in $1000; 45 [23-88] vs. 50 [24-104]; p = 0.004) and higher discharge rate to home (55.7% vs. 48.6%; p < 0.001). Conclusions: More than one-quarter of re-admissions among NSTI survivors were to non-index hospitals. Continuity of care is important because re-admission to the index hospital was associated with better patient outcomes.

Abstract
Background: It is unknown whether having multiple acute care surgery (ACS) procedures performed in one admission confers additional risk. We hypothesized that having multiple procedures (for example, hernia repair plus bowel resection) would be associated with higher mortality. Patients and Methods: We identified all 2017 National Inpatient Sample admissions with ACS procedures including: colon, small bowel/appendix (SB), hernia, adhesiolysis, peptic ulcer procedures, gallbladder, debridement, other laparotomy, other laparoscopy. The total number of procedures for each admission and common dyad (two-procedure) and triad (three-procedure) combinations were identified. Logistic regression estimated the odds of in-hospital mortality for increasing procedure count and specific dyad and triad combinations, using patients with one procedure as the reference. Results: A total of 216,317 ACS patients (median age, 57, interquartile range [IQR], 43-70; 50.6% female) were included; 2.8% died. Patients with multiple procedures were more likely to die than patients with one procedure (7.4% vs. 1.9%). An increasing number of procedures was associated with higher odds of death (two procedures: odds ratio [OR], 3.0; 95% confidence interval [CI], 2.9-3.2] to six or more procedures, OR, 9.5; 95% CI, 4.9-18.5); having more than three procedures was associated with at least fivefold higher odds of death. Specific dyads/triads were associated with particularly high risk of mortality, including ulcer/laparotomy (OR, 15.5; 95% CI, 13.7-17.5) and laparotomy/SB (OR, 8.31; 95% CI, 5.15-13.40). Conclusions: Multiple ACS procedures in one hospitalization confer increased odds of in-hospital mortality. This knowledge enables the ACS providers to better counsel patients by giving more specific expectations regarding mortality based on the number of procedures required or anticipated during an admission.

BACKGROUND Endoscopic esophageal stenting is used as an alternative to surgical repair for esophageal perforation. Multi-institutional studies supporting stenting are lacking. The purpose of this study was to compare the outcomes of surgical repair and esophageal stenting in patients with esophageal perforation using a nationally representative database. We hypothesized that mortality between these approaches would not be different. METHODS The Premier Healthcare Database was used to compare adult inpatients with esophageal perforation receiving either surgical repair or esophageal stenting from 2009 to 2019. Patients receiving intervention ≤7 days of admission were included in the analysis. Patients receiving both stent and repair on the same day were excluded. The composite outcome of interest was death or discharge to hospice. Logistic regression was used to evaluate independent predictors of death or hospice, adjusting for comorbidities. RESULTS There were 2543 patients with esophageal perforation identified who received repair (1314 [51.7%]) or stenting (1229 [48.3%]). Stenting increased from 7.0% in 2009 to 78.1% in 2019. Patients receiving repair were more likely to be female and White and had fewer Elixhauser comorbidities. Death or discharge to hospice was more common after stent (134/1314 [10.2%] repair vs 199/1229 [16.2%] stent; P < .001); however, after adjustment for comorbidities, logistic regression suggested that death or hospice discharge was similar between approaches (stent vs repair: odds ratio, 1.074; 95% CI, 0.81-1.42; P = .622). Hospital length of stay was shorter after stenting (stent vs repair coefficient, -4.09; P < .001). CONCLUSIONS In patients with esophageal perforation, the odds for death or discharge to hospice were similar for esophageal stenting compared with surgical repair.

Abstract
BACKGROUND Current guidelines for follow-up after esophagectomy suggest only history and physical examination (HPE). With recent advances in chemotherapy and immunotherapy for patients with recurrent esophageal cancer, we hypothesized that surveillance imaging (SI) would identify patients with cancer recurrence earlier and improve long-term survival. METHODS A retrospective review of all patients undergoing esophagectomy for esophageal cancer at a single institution between 2007 and 2018 was conducted. Patients were categorized as recurrence detected through SI or recurrence detected through HPE alone. Patients were excluded if recurrence occurred within 3 months of esophagectomy. RESULTS During the study period, 225 esophageal cancer patients underwent an esophagectomy. Among these, 101 (44.9%) had SI and 124 (55.1%) had routine follow-up with HPE. There were 88 recurrences (39.1%) with median follow-up of 12 months. Rate of recurrence was similar based on screening method: 41 of 101 (40.6%) by SI and 47 of 124 (37.9%) by HPE (P = .68). Among patients with recurrence, recipients of additional treatment were also similar between groups, 36 of 41 (87.8%) by SI and 34 of 47 (72.3%) by HPE (P = .468). Among those who had a recurrence, the median overall survival was significantly longer in those undergoing SI at 23 months compared with those who received HPE at 16 months (P = .047). CONCLUSIONS SI after esophagectomy is not associated with improved detection of recurrence, but is associated with improved overall survival once recurrence is detected. These data suggest that earlier identification of esophageal cancer recurrence may have survival benefit. Standardizing SI may prove beneficial for patients after esophagectomy.

Abstract
BACKGROUND Although nearly 1 million older adults are admitted for emergency general surgery conditions yearly, the extent to which baseline health influences the development and treatment of emergency general surgery conditions is unknown. We evaluated baseline health and older patients with and without emergency general surgery conditions. METHODS We used the prospectively collected Medicare Current Beneficiary Survey with Medicare claims and 2 validated health frameworks: (1) Deficit Accumulation Frailty Score and (2) Complex Multimorbidity. Self-reported health and function items were used to derive pre-emergency general surgery conditions Deficit Accumulation Frailty Score and Complex Multimorbidity scores. Deficit Accumulation Frailty Score ranges from 0 (no frailty deficits) to 100 (all possible deficits present). Complex Multimorbidity is a 3-point categorical rank based on the presence of chronic conditions, functional limitations, and geriatric syndromes. Specific survey factors were also examined to determine association with development of emergency general surgery conditions or use of operative management. RESULTS Of 54,417 individuals, 1,960 had emergency general surgery conditions (median age 79 [interquartile range 73-84]). Patients with emergency general surgery conditions had significantly higher Deficit Accumulation Frailty Score (19 [interquartile range 11-31] vs 14 [8-24]) and were more likely to be in the most severe Complex Multimorbidity category (38% vs 29%). Emergency general surgery conditions patients had higher proportions of nearly every health category, with the most striking differences in functional limitations. Patients who were treated nonoperatively had the poorest overall baseline health. CONCLUSION Patients who developed emergency general surgery conditions had more severe health burden than patients who did not, particularly in functional status. Clinicians must better understand the interaction between baseline health vulnerability and emergency surgical disease to improve prognostication and ensure alignment of patient goals and treatment strategies.

Abstract
540 Background: Based on the results of the RxPonder trial, post-menopausal women over age 50 with estrogen receptor (ER)+ breast cancer, 1-3+ nodes, and a 21-gene Oncotype DX recurrence score (RS) score of <25, did not benefit from receiving adjuvant chemotherapy. By contrast, adjuvant chemotherapy was beneficial in premenopausal women. We aimed to replicate the RxPonder trial using a larger sample sizes with real world data to determine whether a threshold with RS exists where adjuvant chemoendocrine therapy (CET) is beneficial regardless of age. Methods: The National Cancer Database (NCDB) was queried for women with ER+, human epidermal growth factor receptor 2 (HER2) negative breast cancer, 1-3 positive axillary nodes, and RS <25 who received endocrine therapy (ET) only or CET. Interaction was explored between CET and age as a surrogate for menopausal status in the Cox regression models. Results: The final analytic cohort included 28,427 eligible women: 7,487 (26.3%) received adjuvant CET and 20,940 (73.7%) ET. In the entire cohort, RS had a normal distribution, with a median score of 14. After correcting for demographic and clinical variables, a threshold effect was observed with RS >20 being associated with a significantly inferior overall survival (OS) (P value range: < 0.001-0.019). In women with RS of 20-25, CET was associated with a significant improvement in OS compared to ET alone, regardless of age (age < = 50: HR = 0.334, P = 0.002; age > 50: HR = 0.521, P = 0.019). Conclusions: Among women with ER+/HER2- breast cancer with 1–3 positive nodes, and RS of 20-25, in contrast to the RxPonder trial we observed that CET was associated with an OS benefit in women regardless of age.

Abstract
543 Background: Early validation studies using the Oncotype DX recurrence score (RS) in NSABP B20 demonstrated that women with node negative breast cancer and RS >31 had significant survival benefit from the addition of adjuvant chemotherapy to endocrine therapy (CET). Consequently, in the prospective TAILORx trial, node negative women with RS >26 received CET. These studies did not clearly delineate the magnitude of benefit of adjuvant chemotherapy for post-menopausal node negative women. A recently published well-designed adjuvant trial (RxPONDER) demonstrated that adjuvant chemotherapy was not beneficial in post-menopausal pts with ER+/HER2- breast cancer, 1-3 positive nodes, and RS <25. We hypothesized that CET would be associated with a modest but statistically significant overall survival (OS) in women with hormone receptor positive ER+/HER2- node negative breast cancer with RS >26 compared to endocrine therapy (ET) alone, given that CET is more beneficial in women <50 years of age. Methods: The National Cancer Database (NCDB) was queried to analyze women age > 50 with ER+/HER2- pT1-2N0M0 breast cancer with RS >26, to assess real world utilization. We separated women into two groups based on adjuvant treatment: ET alone or CET. Chi-square and logistic regression analysis determined difference between different systemic treatment groups. OS was analyzed using a multivariable Cox model. Results: A total of 16,745 eligible women who underwent surgery and received ET were identified in the NCDB—4,740 (28.3%) received ET alone and 12,005 (71.7%) received CET. We observed that CET use increased over time. Women were more likely to receive CET if their tumors were moderately differentiated (OR = 1.853, p < 0.001), poorly/undifferentiated tumors (OR = 3.875, p < 0.001), or associated with lymph-vascular invasion (OR = 1.206, p = 0.001). After accounting for demographic and oncologic factors, 5-year OS rates in this cohort were significantly superior in women receiving CET compared to ET alone (95.4% vs 92.0%, Hazard Ratio = 0.680, p < 0.001). Conclusions: Utilizing the NCDB to represent real world outcomes, we observed that women > 50 years with pT1-2N0M0 ER+/HER2- breast cancer, and RS > 26 had a significantly superior 5-year OS when receiving adjuvant chemotherapy provides a measurable OS benefit for post-menopausal women in this setting and should be discussed with patients.

Abstract
BACKGROUND Race-related health disparities have been well documented in the United States. In some settings, Black patients have better outcomes in hospitals that serve high proportions of Black patients. We hypothesized that Black trauma patients would have lower mortality in high Black-serving (H-BS) hospitals. METHODS We identified all adult patients with Black or White race and with an Injury Severity Score of ≥4 from the 2017 National Inpatient Sample. We collected hospital identifier, mechanism, age, sex, comorbidities, urban-rural location, insurance, zip code income quartile, and injury severity calculated from International Classification of Diseases, Tenth Revision, codes. We used a previously published method to group hospitals by proportion of Black patients served: HB-S (top 5%), medium Black serving (5-25%), and low Black serving (L-BS; bottom 75%). Adjusted logistic regression using an interaction variable between race and hospital service rank (reference: White patients in H-BS) was used to identify factors associated with mortality. RESULTS We analyzed 184,080 trauma patients (median age, 72 years [interquartile range, 55-84 years]; Injury Severity Score, 9 [4-10]), of whom 11.7% were Black. Overall mortality was 4%. Of 2,376 hospitals, 126 (5.3%) were H-BS and 469 (19.7%) were medium Black serving. Furthermore, 29.8% of Black and 3.6% of White patients were treated at H-BS hospitals, while 71.7% of White and 23.6% of Black patients were treated at L-BS hospitals (p < 0.001). Black patients had the lowest mortality at H-BS hospitals (odds ratio [OR], 0.76 [0.64-0.92]) and the highest mortality (OR, 1.43 [1.13-1.80]) at L-BS hospitals. White patients had the lowest mortality at L-BS hospitals (OR, 0.76 [0.64-0.92]). CONCLUSION After adjusting for patient and hospital factors, disparities exist such that Black and White patients have the best outcomes in hospitals that treat those patients most frequently, suggesting potential for racial bias at the institutional level. Further efforts must be made to promote equitable treatment at all hospitals and reduce these disparities. LEVEL OF EVIDENCE Prognostic and Epidemiologic; Level IV.

Abstract
Problem The coronavirus pandemic led to the cancellation of many academic events.
While some transitioned to virtual formats, others disappeared, offering
fewer opportunities for trainees to share research. Facing this challenge,
the Association of Women Surgeons developed a novel
approach. Designed to promote greater global inclusion, increase audience
engagement and opportunities for networking and feedback from practicing
surgeons, they restructured their annual trainee research symposium as a
virtual, multi-round competition. Approach Submission to the research competition was open to trainees at any level. The
competition comprised four rounds: (1) visual abstracts (all welcomed), (2)
three-minute “Quickshot” presentation (32 advance), (3) eight-minute oral
presentations (16 advance), and (4) final question-and-answer style defense
(final 4 compete). Progression through the first three rounds was determined
by public voting. Winners were determined by live voting during the final
session. Outcomes A total of 73 visual abstracts were accepted for presentation. Fifty-six
percent (n = 41) of first authors were medical students, 36% residents (n =
26), and 7% fellows (n = 6). Five were from international first authors
(7%). Abstracts represented research topics including basic science (n = 6,
8%)), clinical outcomes (n = 38, 52%), and education (n = 29, 40%). Social
media impressions exceeded a total of 30,000 views. Next Steps This virtual, multi-round research competition served as a blueprint for a
novel approach to research dissemination. The format enabled expanded US
national and international engagement with trainees in all stages of their
career. Future research symposia should consider the impact of popularity
bias, timing, and voting strategies during the event planning period to
optimize success.

Abstract
Importance Although nearly 1 million older patients are admitted for emergency general surgery (EGS) conditions yearly, long-term survival after these acute diseases is not well characterized. Many older patients with EGS conditions have preexisting complex multimorbidity defined as the co-occurrence of at least 2 of 3 key domains: chronic conditions, functional limitations, and geriatric syndromes. The hypothesis was that specific multimorbidity domain combinations are associated with differential long-term mortality after patient admission with EGS conditions. Objective To examine multimorbidity domain combinations associated with increased long-term mortality after patient admission with EGS conditions. Design, Setting, and Participants This cohort study included community-dwelling participants aged 65 years and older from the Medicare Current Beneficiary Survey with linked Medicare data (January 1992 through December 2013) and admissions for diagnoses consistent with EGS conditions. Surveys on health and function from the year before EGS conditions were used to extract the 3 domains: chronic conditions, functional limitations, and geriatric syndromes. The number of domains present were summed to calculate a categorical rank: no multimorbidity (0 or 1), multimorbidity 2 (2 of the 3 domains present), and multimorbidity 3 (all 3 domains present). Whether operative treatment was provided during the admission was also identified. Data were cleaned and analyzed between January 16, 2020, and April 29, 2021. Exposures Mutually exclusive multimorbidity domain combinations (functional limitations and geriatric syndromes; functional limitations and chronic conditions; chronic conditions and geriatric syndromes; or functional limitations, geriatric syndromes, and chronic conditions). Main Outcomes and Measures Time to death (up to 3 years from EGS conditions admission) in patients with multimorbidity combinations was analyzed using a Cox proportional hazards model and compared with those without multimorbidity; hazard ratios (HRs) and 95% CIs are presented. Models were adjusted for age, sex, and operative treatment. Results Of 1960 patients (median [IQR] age, 79 [73-85] years; 1166 [59.5%] women), 383 (19.5%) had no multimorbidity, 829 (42.3%) had 2 multimorbidity domains, and 748 (38.2%) had all 3 domains present. A total of 376 (19.2%) were known to have died in the follow-up period, with a median (IQR) follow-up of 377 (138-621) days. Patients with chronic conditions and geriatric syndromes had a mortality risk similar to those without multimorbidity. However, all domain combinations with functional limitations were associated with significantly increased risk of death: functional limitations and chronic conditions (HR, 1.83; 95% CI, 1.03-3.23); functional limitations and geriatric syndromes (HR, 2.91; 95% CI, 1.37-6.18); and functional limitations, geriatric syndromes, and chronic conditions (HR, 2.08; 95% CI, 1.49-2.89). Conclusions and Relevance Findings of this study suggest that a patient's baseline complex multimorbidity level efficiently identifies risk stratification groups for long-term survival. Functional limitations are rarely considered in risk stratification paradigms for older patients with EGS conditions compared with chronic conditions and geriatric syndromes. However, functional limitations may be the most important risk factor for long-term survival.

[PMID: 35363881 DOI: 10.1002/cncr.34200] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 03/03/2022] [Accepted: 03/04/2022] [Indexed: 12/26/2022]
Abstract
BACKGROUND Small invasive breast cancers (BCs) with tumor sizes ≤5 mm (T1a) are associated with an excellent prognosis without systemic therapy. Although HER2 overexpression (HER2+) is associated with a higher risk of recurrence and poorer clinical outcomes, in the absence of HER2 directed therapy, it remains unclear whether adjuvant systemic therapy is necessary in node-negative patients diagnosed with HER2+ invasive BCs ≤5 mm (pT1aN0M0). METHODS The National Cancer Database was searched to identify patients diagnosed with HER2+ pT1aN0M0 BCs from 2004 to 2017. The cohort was stratified by treatment status: local therapy alone or local plus adjuvant systemic therapy. A 1:1 propensity match was performed. Overall survival (OS) was analyzed using stratified multivariable Cox proportional hazards regression analyses. RESULTS Of the 8948 patients found, 4026 (45.0%) underwent surgery alone, and 4922 (55.0%) received surgery plus systemic therapy. Patients with either moderately differentiated (odds ratio [OR], 2.053; P < .001) or poorly/undifferentiated tumors (OR, 3.780; P < .001) or with the presence of lymphovascular invasion (OR, 3.351; P < .001) were more likely to have received systemic therapy. Propensity matching generated 1162 pairs of patients who were hormone receptor positive (HR+) and 748 pairs who were hormone receptor negative (HR-). Propensity matching effectively reduced selection bias between study groups. In the matched cohort, the addition of systemic therapy was not associated with superior OS (hazard ratio for HR+, 1.613; P = .107, and hazard ratio for HR- 1.319; P = .369) compared with patients who received local therapy alone. CONCLUSIONS In pT1aN0M0 HER2+ BC, the addition of adjuvant systemic therapy after surgical excision was not associated with improved OS compared with local therapy alone.

Abstract
BACKGROUND The perioperative risk of pulmonary lobectomy as a solitary procedure has been extensively studied, yet the differences in outcomes between each lobe, which have unique anatomy and a different amount of lung parenchyma, are entirely unknown. The purpose of this study is to define the risk of each of the five lobectomies. METHODS The Society of Thoracic Surgery Database was queried for patients undergoing lobectomy between 2008 and 2018. Patient and disease characteristics, operative variables, major morbidity and 30-day mortality were examined. A multivariable logistic regression model (using the same variables in the current STS lobectomy risk model) was developed to assess for the contribution to lobectomy site to adverse outcomes. RESULTS 65,006 patients were analyzed. Adjusted perioperative mortality rate is lowest for RML (0.63%) intermediate for RUL, LUL and LLL (1.08-1.24%), and highest for RLL (1.63%). The adjusted major morbidity rate is lowest for RML (5.36%) intermediate for LLL and LUL (7.82-8.33%), and highest for RUL and RLL (8.94-9.32%). Adjusted intraoperative transfusion rate is lowest for RML (1.37%) intermediate for RLL and LLL (1.81-1.94%) and highest for RUL and LUL (2.47-2.72%). CONCLUSIONS There are clear differences in postoperative outcomes by lobectomy location. Mortality, major morbidity, and transfusion rate are lowest for RML, but vary across other lobectomies. These differences should be appreciated when evaluating risk of operation, deciding upon best therapy, counseling patients, and comparing outcomes.
