RESUMEN
INTRODUCTION: Primary tracheal cancer is uncommon, with poor survival. While surgical resection is the mainstay of therapy, the role of chemotherapy and radiation is poorly defined. We aimed to study the impact of treatment modalities on survival. METHODS: Patients with primary tracheal cancer were identified from the National Cancer Database over 12 years, 2004-2015. Patient characteristics, tumor characteristics, treatment modalities, and survival were recorded. Factors associated with survival were assessed using Cox Regression. RESULTS: Of the 1726 patients identified, 59% were male, 83% White race, 62% had a comorbidity index of zero, median age 64 years, median tumor size 2.7 cm, and median survival was 28.5 months (89 months for patients undergoing surgical resection). Cox Regression for all patients found adenoid cystic carcinoma (ACC) (p < 0.001), radiation (p < 0.001), and surgical resection (p < 0.001) to be associated with improved survival, while increasing age (p < 0.001) decreased survival. For patients receiving resection, ACC (p < 0.001) was associated with improved survival, while increasing age (p < 0.001) and positive margins (p = 0.002) were associated with worse survival. For R0 resections, ACC (p < 0.001) was associated with improved survival, while increasing age (p < 0.001) decreased survival, with chemotherapy and radiation having no impact. For R1/2 resections, ACC (p < 0.001) and radiation (p < 0.001) were associated with improved survival, while increasing age (p < 0.001) decreased survival, with chemotherapy having no impact on survival. CONCLUSIONS: Primary tracheal cancer is highly lethal, with surgical resection leading to the best chance of survival. For patients undergoing resection, radiation provided survival benefits for R1/2 but not R0, while chemotherapy did not impact survival regardless of margin status.

OBJECTIVE: Enhanced Recovery ERP protocols (ERP) have improved surgical outcomes in patients undergoing elective colon cancer (CC) surgery; however, efficacy in different populations may vary. We examined the impact of an ERP in a population with high rates of obesity and multiple comorbidities. METHODS: We performed a retrospective analysis of factors associated with postoperative complications (PoC) and length of stay (LOS) following CC surgery from 2011 to 2019 in a 5-hospital healthcare system which serves a population with higher rates of obesity (body mass index ≥30kg/m2) and multi-comorbidities, as compared to published studies. Univariable and multivariable analyses were performed. RESULTS: A total of 408 elective CC surgery patients with complete oncologic surgical data were identified. Of these, 191 (46.81%) were under ERP. Factors independently associated with PoC included obesity (OR=1.66, P=.029), laparoscopic (OR=.52, P=.020), and hybrid (OR=.38, P=.012) versus open surgery and ASA (American Society of Anesthesiologists) class ≥3 (OR=1.98, P=.006). ERP did not impact PoC but was associated with a reduction in LOS (ß=-1.02 days, 95%CI: -1.75 - -.30, P=.006). ERP had an impact on LOS in both the non-obese and obese groups (P<.001 and P=.034, respectively). PoC significantly increased LOS (ß=6.67 days, 95%CI: 5.41-7.03, P<.001). CONCLUSIONS: Following elective CC surgery, obesity and medical comorbidities were associated with increased PoC and in turn, as expected, increased LOS. ERP was associated with a reduction in LOS in both obese and non-obese patients. In high-risk populations, application of ERP may be particularly important to optimize surgical outcomes following CC surgery.

BACKGROUND: Laparoscopic Heller myotomy (LHM) and esophageal balloon dilation (BD) are the two mainstays of achalasia treatment-this study examines the outcomes when they are performed simultaneously without fundoplication. METHODS: All patients undergoing LHM&BD were reviewed for demographic and procedural data, and to see if additional procedures for achalasia had been performed. Patients were surveyed using the Eckardt score and the GERD quality-of-life score (GERD-HRQL) to assess the durability of repair. RESULTS: From 2013-2020, 66 patients underwent LHM&BD. There were no esophageal perforations and a median LOS of 1 day. Seven patients have required additional operations or procedures at median 4-years follow up. 31 patients (47%) responded to the survey. The average Eckardt score was 2.9 (goal<4) with mean GERD-HRQL of 14.4 (goal<25). CONCLUSIONS: LHM&BD allows for a safe, durable repair of achalasia. Reflux symptoms are manageable with PPI without fundoplication and the re-intervention rate similar to published values.

BACKGROUND AND OBJECTIVES: Visceral angiosarcoma is rare and aggressive, accounting for 2% of soft tissue sarcomas. Using a national data set, we examine determinants of outcomes for patients presenting with this rare disease. METHODS: The 2004-2015 National Cancer Database was queried for patients with visceral angiosarcoma. Trends in treatment and outcomes were examined. Factors affecting overall survival (OS) were assessed with log-rank and Cox regression. RESULTS: Eight hundred and ninety-three patients with visceral angiosarcoma were identified (median age 65 years, male [63%], Charlson comorbidity index <1 [86%]). Tumor size was <5 cm in 20.7%, and 34.2% were moderate/high grade. Median OS was 3.8 months (95% CI: 3.4-4.4). By multivariate analysis, increased tumor grade and size, and liver/biliary origin demonstrated worse OS while surgery, radiation, and systemic chemotherapy demonstrated improved OS (all p < 0.001). Survival was similar between patients achieving R0 resection and those with R1/2 resection receiving chemotherapy by Kaplan-Meier analysis. CONCLUSIONS: Visceral angiosarcomas are rare tumors with poor outcomes. Liver/biliary origin, higher tumor grade, and larger tumor size demonstrate worse outcomes. While R0 resection remains the mainstay of treatment, patients with R1/R2 resection have improved survival with addition of chemotherapy. Consideration should be made for multimodal therapy in these patients.

BACKGROUND: Anal melanoma is rare. Surgery is standard of care for non-metastatic disease. There are limited data supporting adjuvant therapy. We sought to examine the impact of adjuvant radiation, chemotherapy and immunotherapy on survival. METHODS: The National Cancer Database was queried. Factors associated with overall survival were examined by Kaplan-Meier and Cox proportional hazards analyses. Patients were grouped by treatment regimen. RESULTS: 450 patients had complete treatment data: surgery alone (63.8%), surgery + radiation (14.9%), surgery + chemotherapy (7.6%), surgery + immunotherapy (9.6%) and non-surgical treatment (4.2%). Median survival was 27.2 months. Node-positive patients had worse survival than node-negative (22.4 vs. 36.8 months; p = 0.0002). Non-surgical treatment yielded worse survival than any surgery-inclusive regimen (10.4 vs. 27.8 months; p = 0.0002). No adjuvant modality conferred a survival advantage. By multivariate analysis, increasing age (HR/1 year = 1.02, p = 0.012) and node positivity (HR = 2.10, p = 0.0002) negatively impacted survival. CONCLUSION: Adjuvant therapy for non-metastatic anal melanoma does not appear to influence survival.

BACKGROUND: Practice guidelines recommend neoadjuvant chemoradiation (NCR) for locally advanced rectal cancer (LARC). We examined guideline adherence in a healthcare system serving a region with socioeconomic disparities and poor cancer outcomes. METHODS: Retrospective analysis of factors associated with guideline adherence. RESULTS: 63.1% of stage II/III LARC patients received NCR. Factors associated with adherence included white race (OR = 2.15, p = 0.024), private insurance (OR = 2.70, p = 0.005), employed status (OR = 2.30, p = 0.031), age at diagnosis (OR = 0.74, p = 0.032), appropriate local staging (OR = 9.17, p < 0.0001), and diagnosis later in the study period (OR per 1 year = 1.20, p = 0.006). By multivariate analysis, private insurance (OR = 2.51, p = 0.023), younger age (OR per 10 years = 0.72, p = 0.048) and appropriate local staging (OR = 6.67, p < 0.0001) were associated with adherence. CONCLUSION: Guideline adherence for LARC in our system is low and is impacted by employment, race and insurance status. Standard of care compliance remains an important target for improvement efforts in this underserved region of the nation's Mid-South.
