BACKGROUND: The incidence of esophageal cancer (EC) is increasing in the USA. Neoadjuvant therapy for locally advanced cancers followed by surgical resection is the standard of care. The most common post-esophagectomy cardiac complication is atrial fibrillation (AF). New-onset postoperative AF can require a prolonged hospital stay and may confer an overall poorer prognosis. In this study, we seek to identify clinical factors associated with postoperative AF. METHODS: Query of an IRB approved database of 1,039 esophagectomies at our institution revealed 677 patients with EC from 1999 to 2017 who underwent esophagectomy after neoadjuvant treatment. Age, treatment location (primary vs. other), gender, neoadjuvant radiation type [2D vs. 3D vs. intensity modulated radiation therapy (IMRT)], radiation dose, surgery type (transthoracic vs. transhiatal vs. three field), smoking history, coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD), operative time, blood transfusions, fluid management, and length of stay (LOS) were analyzed in relationship to the development of AF. Statistical analysis was performed with SPSS 24. RESULTS: The mean age of the entire cohort was 64.3 (range, 28–86 years), with a Caucasian and male preponderance (White: 94.5%; male: 83.6%). Of the 677 patients, 14.9% (n=101) developed postoperative AF. Increasing age (P

Objective: Gastrostomy tubes (g-tubes) have been used with caution prior to esophageal resection due to the risks of inoculation metastasis and of injury to the gastric conduit used for reconstruct...

Objective To evaluate perioperative and oncologic outcomes in our RAMIE cohort and compare outcomes with contemporary OE controls. Summary of background data RAMIE has emerged as an alternative to traditional open or laparoscopic approaches. Described in all esophagectomy techniques, rapid adoption has been attributed to both enhanced visualization and technical dexterity. Methods We retrospectively reviewed patients who underwent RAMIE for malignancy. Patient characteristics, perioperative outcomes, and survival were evaluated. For perioperative and oncologic outcome comparison, contemporary OE controls were propensity-score matched from NSQIP and NCDB databases. Results We identified 350 patients who underwent RAMIE between 2010 and 2019. Median body mass index was 27.4, 32% demonstrated a Charlson Comorbidity Index ≥4. Nodal disease was identified in 50% of patients and 74% received neoadjuvant chemoradiotherapy. Mean operative time and blood loss were 425 minutes and 232 mL, respectively. Anastomotic leak occurred in 16% of patients, 2% required reoperation. Median LOS was 9 days, and 30-day mortality was 3%. A median of 21 nodes were dissected with 96% achieving an R0 resection. Median survival was 67.4 months. 222 RAMIE were matched 1:1 to the NSQIP OE control. RAMIE demonstrated decreased LOS (9 vs 10 days, P = 0.010) and reoperative rates (2.3 vs 12.2%, P = 0.001), longer operative time (427 vs 311 minutes, P = 0.001), and increased rate of pulmonary embolism (5.4% vs 0.9%, P = 0.007) in comparison to NSQIP cohort. There was no difference in leak rate or mortality. Three hundred forty-three RAMIE were matched to OE cohort from NCDB with no difference in median overall survival (63 vs 53 months; P = 0.130). Conclusion In this largest reported institutional series, we demonstrate that RAMIE can be performed safely with excellent oncologic outcomes and decreased hospital stay when compared to the open approach.

The incidence of esophageal cancer is increasing in the United States. Although neoadjuvant therapy (NAT) for locally advanced cancers followed by surgical resection is the standard of care, there are no clearly defined guidelines for patients aged ≥79 y.Query of an institutional review board-approved database of 1031 esophagectomies at our institution revealed 35 patients aged ≥79 y from 1999 to 2017 who underwent esophagectomy. Age, gender, tumor location, histology, clinical stage, Charlson Comorbidity Index (CCI), NAT administration, pathologic response rate to NAT, surgery type, negative margin resection status, postoperative complications, postoperative death, length of stay, 30- and 90-d mortality, and disease status parameters were analyzed in association with clinical outcome.The median age of the octogenarian cohort was 82.1 y with a male preponderance (91.4%). American Joint Committee on Cancer clinical staging was stage I for 20% of patients, stage II for 27% of patients, and stage III for 50% of patients, which was not statistically significant compared with the younger cohort (P = 0.576). Within the octogenarian group, 54% received NAT compared with 67% in the younger group (P = 0.098). There was no difference in postoperative complications (P = 0.424), postoperative death (P = 0.312), and recurrence rate (P = 0.434) between the groups. However, CCI was significantly different between the octogenarian and nonoctogenarian cohort (P = 0.008), and octogenarians had shorter overall survival (18 versus 62 mo, P0.001). None of the other parameters assessed were associated with clinical outcomes.Curative surgery is viable and safe for octogenarians with esophageal cancer. Long-term survival was significantly shorter in the octogenarian group, suggesting the need for better clinical selection criteria for esophagectomy after chemoradiation and that identification of complete responders for nonoperative management is warranted.

170 Background: Few epidemiological studies address differences in outcomes by gender in locoregional esophageal cancer (LEC) for which the current standard of care is chemoradiation followed by surgical resection. Although male gender is associated with the majority of LEC cases, we sought to determine if gender could impact clinical presentation as well as surgical and oncologic outcomes in our single institution 20 year experience. Methods: A retrospective query of our institution’s IRB-approved database of patients that had surgical therapy between 2008 and 2019 for esophageal cancer (EC) was performed. Patients were stratified by gender and analyzed based on characteristics such as tumor histology, tumor location, clinical stage at presentation, age at diagnosis, receipt of neoadjuvant therapy, surgical intent, surgical complications, length of post-operative hospital stay, response to neoadjuvant therapy, final pathology, and recurrence. Chi-square, ANOVA and Kaplan Meier survival analysis were performed on the previously defined groups. Results: The cohort studied included 1180 patients with resection for EC. Of those, 1005 (85.2%) had adenocarcinoma, 145 (12.3%) had squamous cell cancer (SCC), 10 (0.8%) had adenosquamous carcinoma, and 20 (1.7%) had other histological variants. There were 985 (83.5%) male patients and 195 (16.5%) female patients. SCC was more common in females (29.2% in females vs. 8.9% in males, p = 0.000) and females tended to have tumor location in the upper thoracic esophagus more often (4.7% in females vs. 0.9% of males, p = 0.000). Additionally, females developed surgical complications more often than males (72.2% vs. 64.7%, p = 0.045). Staging at diagnosis (p = 0.508), receipt of neoadjuvant treatment (p = 0.676), and age at diagnosis (65.3 years in males vs. 66.3 years in females, p = 0.934) had no association with gender. Response to neoadjuvant therapy (p = 0.157) and cancer recurrence (p = 0.434) did not have significant associations with gender. The median overall survival was not statistically significantly different but trended to be longer for females (73.4 months in females [95% CI: 51.5-95.4] vs. 47.0 months in males [95% CI: 39.6-54.5], p = 0.160). Conclusions: Based on our high-volume cancer center study, female patients were more likely to have SCC, upper thoracic esophageal lesions, and surgical complications following resection. While univariate analysis did not demonstrate significant differences in overall survival between genders, there are plans to report additional data after controlling for other variables. Further studies are warranted to validate these findings, given the potential for higher prioritization of an organ preservation approach for this patient population.
