OBJECTIVE: To evaluate whether pathologic complete response (pCR) exclusively defines major pathologic response to treatment with improved survival. SUMMARY BACKGROUND DATA: pCR following trimodality therapy for esophagogastric adenocarcinoma is infrequent but associated with improved prognosis. Yet most clinical trials and correlative studies designate pCR as the primary endpoint. METHODS: We analyzed our prospectively maintained database for patients who underwent trimodality therapy for locally advanced esophageal adenocarcinoma between 1995 and 2017. Overall survival (OS) was examined by percentage treatment response (TR) in the primary tumor bed and pathologic nodal stage (ypN0) using Kaplan-Meier plots. Optimal thresholds of TR for differentiating patients in terms of OS were investigated with descriptive plots using restricted cubic spline functions; associations were quantified using Cox multivariable analysis. RESULTS: Among 788 patients, median follow-up was 37.5 months (range, 0.4–210.6); median OS was 48.3 months (95% CI, 42.2–58.8). Absence of residual nodal disease was independently associated with improved survival (P

The misuse of opioids is a serious national crisis that is fueled by prescriptions medications. Opioid prescribing habits are known to be highly varied amongst providers. The purpose of this study is to identify patient and surgeon characteristics that predict postoperative opioid prescribing patterns.This is a serial cross-sectional analysis of 20,497 patients who underwent general surgical procedures at a large academic center. Our primary outcome was the total amount of opioids prescribed within 30 days of the surgery. Univariate and multivariate linear regression models were used to identify patient and provider characteristics that were associated with increased opioids prescribed.Among patient characteristics studied, patient age, sex, ethnicity, and insurance status were found to have a significant association with the amount of opioids prescribed. Younger patients and male patients received higher morphine milligram equivalents (MMEs) on discharge (p 0.05). Patients of Hispanic background were prescribed significantly lower opioids compared to Non-Hispanic patients (p 0.0001). Among the provider characteristics studied, surgeon sex and years in practice were significantly predictive of the amount of opioids prescribed, with surgeons in practice for15 years prescribing the highest MMEs (p 0.0001).While opioid prescribing habits after surgery seem highly varied and arbitrary, we have identified key predictors that highlight biases in surgeon opioid prescribing patterns. Surgeons tend to prescribe significantly larger amounts of opioids to younger, male patients and those of certain ethnic backgrounds, and surgeons with fewer years in practice are more likely to prescribe more opioids.

Background This study evaluates the safety and feasibility of combined resection for patients with synchronous pulmonary and esophageal cancer. Methods Patients undergoing esophagectomy between 1997 and 2019 were identified from prospectively collected databases at three tertiary referral centers, and those with combined anatomic lung resection at the same setting were identified. This cohort was then matched in a 1:3 ratio to esophagectomy alone cases, based on age, sex, pathologic stage, neoadjuvant therapy, and surgical procedure. Demographic data, peri-operative data, post-operative complications were compared. Statistical analysis included unpaired t-test, Fisher’s exact or chi-squared test and Gehan-Breslow analysis. Results Of 4729 esophagectomies, combined anatomic lung resection was performed in 18 patients with discrete pulmonary lesions. Matching yielded 49 patients who underwent esophagectomy only and was statistically similar compared to patients undergoing combined resections. Ivor Lewis esophagectomy and lobectomy were the most frequent procedures. Combined resections did not have a higher overall complication rate than esophagectomy alone, rather these patients had fewer overall complications (56% vs 84%; p=0.02). Specifically, there was not difference in anastomotic leak (17% vs. 18%) or pulmonary complications (39% vs. 33%) between combined resection and esophagectomy alone. No post-operative mortality was identified, and median overall survival was 4.1 years versus 6.5 years (p=0.10). Conclusions Patients with synchronous localized lung and esophageal cancer, although rare, should not be biased towards non-surgical therapy, as the morbidity associated with combined esophagectomy and anatomic lung resection does not differ significantly from esophagectomy alone in this highly selected group of patients.

BACKGROUND: More than half of patients treated with esophagectomy for esophageal cancer experience recurrence. Oligometastasis, a proposed intermediate state of isolated local or solid-organ recurrence that occurs before widespread systemic disease, is a potential target for aggressive local intervention. We investigated presentation and prognosis between solid-organ recurrence sites. METHODS: Patients with isolated solid-organ recurrence at the liver, lung, or brain who underwent R0 esophagectomy from 1995 to 2016 were identified. Clinicopathologic characteristics and outcomes were compared between sites of recurrence. Overall survival was quantified using the Kaplan-Meier approach and Cox proportional hazards models. RESULTS: In total, 104 patients were included (site: brain, 37; lung, 27; liver, 40). Eighty percent of liver, 51% of brain, and 44% of lung oligometastases occurred in the first 12 months after esophagectomy. Despite the limited use of aggressive therapy, patients with lung oligometastasis had significantly longer median overall survival (2.41 years; 95% confidence interval [CI], 1.58–3.31) than patients with brain (0.95 years; 95% CI, 0.62–1.49) or liver (0.95 years; 95% CI, 0.82–1.41) oligometastasis (p

As endoscopic approaches become more widely used to treat early-stage esophageal cancer, reliably identifying patients with less-aggressive tumors is paramount. We sought to identify risk factors for recurrence in patients with completely resected T1 esophageal adenocarcinoma.We retrospectively analyzed a single-institutional database for all patients with completely resected pathologic T1 esophageal adenocarcinoma (1996-2016). Risk factors for recurrence were identified using competing-risk regression methods. Risk stratification was performed on the basis of known preoperative clinicopathologic factors; this model's discriminative power for overall survival was evaluated using a Cox proportional hazards model.Of 243 patients, 32 experienced recurrence. At a median follow-up among survivors of 4 years (range, 0.05-19 years), the 5-year cumulative incidence of recurrence was 15%, and median time to recurrence was 2 years (range, 0.26-6.13 years). On univariable analysis, submucosal invasion, N1 disease, poor differentiation, tumor length, lymphovascular invasion, and multicentricity were significantly associated with recurrence. On multivariable analysis, N1 disease (hazard ratio, 2.93; 95% confidence interval, 1.17-7.34; P = .022) and tumor length (hazard ratio, 1.44; 95% confidence interval, 1.12-1.86; P = .004) were independently associated with recurrence. Risk stratification showed that patients without lymphovascular invasion and a with median tumor length of 0.8 cm (range, 0.10-1.70 cm) had a10% risk of recurrence and improved survival.Pathologic T1 tumors have a 5-year cumulative incidence of recurrence of 15%. Nodal involvement and tumor length were independent risk factors for recurrence, whereas tumors2 cm in length without lymphovascular invasion were associated with a low risk of recurrence.

Background Accurate preoperative risk assessment is necessary for informed decision making for patients and surgeons. Several preoperative risk calculators are available but few have been examined in the general thoracic surgical patient population. The Surgical Risk Preoperative Assessment System (SURPAS), a risk-assessment tool applicable to a wide spectrum of surgical procedures, was developed to predict the risks of common adverse postoperative outcomes using a parsimonious set of preoperative input variables. We sought to externally validate the performance of SURPAS for postoperative complications in patients undergoing pulmonary resection. Methods Between January 2016 and December 2018, 2514 patients underwent pulmonary resection at our center. Using data from our institution's prospectively maintained database, we calculated the predicted risks of 12 categories of postoperative outcomes using the latest version of SURPAS. Performance of SURPAS against observed patient outcomes was assessed by discrimination (concordance index) and calibration (calibration curves). Results The discrimination ability of SURPAS was moderate across all outcomes (concordance indices, 0.640 to 0.788). Calibration curves indicated good calibration for all outcomes except infectious and cardiac complications, discharge to a location other than home, and mortality (all overestimated by SURPAS). Conclusions SURPAS demonstrates outcomes for pulmonary resections with reasonable predictive ability. Discretion should be applied when assessing risk for postoperative infectious and cardiac complications, discharge to a location other than home, and mortality. Although the parsimonious nature of SURPAS is one of its strengths, its performance might be improved by including additional factors known to influence outcomes after pulmonary resection, such as sex and pulmonary function.

Background Accurate preoperative risk assessment is critical for informed decision making. The Surgical Risk Preoperative Assessment System (SURPAS) and the National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator (SRC) predict risks of common postoperative complications. This study compares observed and predicted outcomes after pulmonary resection between SURPAS and NSQIP SRC. Methods Between January 2016 and December 2018, 2514 patients underwent pulmonary resection and were included. We entered the requisite patient demographics, preoperative risk factors, and procedural details into the online NSQIP SRC and SURPAS formulas. Performance of the prediction models was assessed by discrimination and calibration. Results No statistically significant differences were found between the 2 models in discrimination performance for 30-day mortality, urinary tract infection, readmission, and discharge to a nursing or rehabilitation facility. The ability to discriminate between a patient who will develop a complication and a patient who will not was statistically indistinguishable between NSQIP and SURPAS, except for renal failure. With a C index closer to 1.0, the NSQIP performed significantly better than the SURPAS SRC in discriminating risk of renal failure (C index, 0.798 vs 0.694; P = .003). The calibration curves of predicted and observed risk for each model demonstrate similar performance with a tendency toward overestimation of risk, apart from renal failure. Conclusions Overall, SURPAS and NSQIP SRC performed similarly in predicting outcomes for pulmonary resections in this large, single-center validation study with moderate to good discrimination of outcomes. Notably, SURPAS uses a smaller set of input variables to generate the preoperative risk assessment. The addition of thoracic-specific input variables may improve performance.

Background Studies demonstrate wide variation in postoperative opioid prescribing and that patients are at risk of chronic opioid abuse after surgery. The factors that influence prescribing, however, remain obscure. This study investigates whether day of the week or the postoperative day at the time of discharge impacts prescribing patterns. Methods We identified patients who underwent commonly performed procedures at our institution from January 2014 through April 2019 and analyzed the relationship between postoperative opioids prescribed (oral morphine milligram equivalents) and both the day of the week and the postoperative day at discharge. Results In ambulatory operations (n = 13,545), each day progressing from Monday was associated with increased morphine milligram equivalents prescribed on discharge (P = .0080). For inpatient cases (n = 10,838), surgeons prescribed more morphine milligram equivalents at discharge in the latter half of the week and during the weekend (P = .0372). Every additional postoperative day at discharge was associated with a +19.25 morphine milligram equivalent prescribed (P Conclusion More opioids were prescribed on discharges later in the week and after prolonged hospital stays perhaps to avoid patients running out of medication. Providers may unintentionally allow such non-clinical factors to influence postoperative opioid prescribing. Increased awareness of these inadvertent biases may help decrease excess prescribing of potentially addicting opioids after an operation.

Objective We sought to determine the extent of lymphadenectomy that optimizes staging and survival in patients with locally advanced esophageal adenocarcinoma (EAC) treated with neoadjuvant chemoradiotherapy followed by esophagectomy. Summary background data Several studies have found that a more extensive lymphadenectomy leads to better disease-specific survival in patients treated with surgery alone. Few studies, however, have investigated whether this association exists for patients treated with neoadjuvant chemoradiotherapy. Methods We examined our prospective database and identified patients with EAC treated with neoadjuvant chemoradiotherapy followed by esophagectomy between 1995 and 2017. Overall survival (OS) and disease-free survival (DFS) were estimated using Kaplan-Meier methods, and a multivariable Cox proportional hazards model was used to identify independent predictors of OS and DFS. The relationship between the total number of nodes removed and 5-year OS or DFS was plotted using restricted cubic spline functions. Results In total, 778 patients met the inclusion criteria. The median number of excised nodes was 21 (interquartile range, 16-27). A lower number of excised lymph nodes was independently associated with worse OS and DFS (OS: hazard ratio [HR], 0.98; confidence interval [CI], 0.97-1.00; P = 0.013; DFS: HR, 0.99; CI, 0.98-1.00; P = 0.028). Removing 25 to 30 lymph nodes was associated with a 10% risk of missing a positive lymph node. Both OS and DFS improved with up to 20 to 25 lymph nodes removed, regardless of treatment response. Conclusions The optimal extent of lymphadenectomy to enhance both staging and survival following chemoradiotherapy, regardless of treatment response, is approximately 25 lymph nodes.

Background Racial disparities in New York City (NYC) breast cancer incidence and mortality rates have previously been demonstrated. Disease stage at diagnosis and mortality‐to‐incidence ratio (MIR) may present better measures of differences in screening and treatment access. Racial/ethnic trends in NYC MIR have not previously been assessed. Methods Mammogram rates were compared using the NYC Community Health Survey, 2002‐2014. Breast cancer diagnosis, stage, and mortality were from the New York State Cancer Registry, 2000‐2016. Primary outcomes were MIR, the ratio of age‐adjusted mortality to incidence rates, and stage at diagnosis. Joinpoint regression analysis identified significant trends. Results Mammogram rates in 2002‐2014 among Black and Latina women ages 40 and older (79.9% and 78.4%, respectively) were stable and higher than among White (73.6%) and Asian/Pacific‐Islander women (70.4%) (P, Lower incidence of local stage breast cancer at diagnosis and slower decrease in mortality rates among Black and Latina women in NYC as compared to White women raises great concern about unequal access to quality care including quality screening and improvements in therapy. These differences were especially prominent among Black women, who merit additional public health focus.

Background Since 1999, >200 000 people in the United States have died from a prescription opioid overdose. Lower socioeconomic status (SES) is one important risk factor. This study investigates socioeconomic disparities in postoperative opioid prescription and consumption. Methods September 2018-April 2019, 128 patients were surveyed postoperatively regarding opioid consumption. The neighborhood disadvantage was calculated using area deprivation index (ADI). The top 3 quartiles were “high SES” and the bottom quartile “low SES.” Results The study population included 96 high SES patients, median ADI 6 (2-12.3) and 32 low SES, median ADI 94.5 (81.3-97.3). For both, median Oxycodone 5 mg prescribed was 20 pills. 29.2% of high SES consumed 0 pills, 40.6% consumed 1-9 pills, and 27.1% consumed 10+ pills. 25.0% of low SES consumed 0 pills, 46.9% consumed 1-9 pills, and 18.8% consumed 10+ pills. No significant difference in opioid prescription ( P = .792) or consumption ( P = .508) between SES groups. Discussion Patients of all SES are prescribed and consumed opioids in similar patterns with no significant difference in postoperative pain following ambulatory surgery.

Background Breast cancer is the most common malignancy among women in the USA. Improved survival has resulted in increasing incidence of second primary malignancies, of which lung cancer is the most common. The United States Preventive Services Task Force (USPSTF) guidelines for lung-cancer screening do not include previous malignancy as a high-risk feature requiring evaluation. The aim of this study was to compare women undergoing resection for lung cancer with and without a history of breast cancer and to assess whether there were differences in stage at diagnosis, survival and eligibility for lung-cancer screening between the two groups. Methods Women who underwent lung-cancer resection between 2000 and 2017 were identified. Demographic, clinicopathological, treatment and outcomes data were compared between patients with a history of breast cancer (BC-Lung) and patients without a history of breast cancer (P-Lung) before lung cancer. Results Of 2192 patients included, 331 (15.1 per cent) were in the BC-Lung group. The most common method of lung-cancer diagnosis in the BC-Lung group was breast-cancer surveillance or work-up imaging. Patients in the BC-Lung group had an earlier stage of lung cancer at the time of diagnosis. Five-year overall survival was not statistically significantly different between groups (73.3 per cent for both). Overall, 58.4 per cent of patients (1281 patients) had a history of smoking, and 33.3 per cent (731 patients) met the current criteria for lung-cancer screening. Conclusion Differences in stage at diagnosis of lung cancer and treatment selection were observed between patients with and without a history of breast cancer. Overall, there were no statistically significant differences in genomic or oncogenic pathway alterations between the two groups, which suggests that lung cancer in patients who previously had breast cancer may not be affected at the genomic level by the previous breast cancer. The most important finding of the study was that a high percentage of women with lung cancer, regardless of breast-cancer history, did not meet the current USPSTF criteria for lung-cancer screening., Differences in stage at diagnosis of lung cancer and treatment selection were observed between patients with and without a history of breast cancer. Overall, there were no statistically significant differences in genomic or oncogenic pathway alterations between the two groups, which suggests that lung cancer in patients who previously had breast cancer may not be affected at the genomic level by the previous breast cancer. The most important finding of the study was that a high percentage of women with lung cancer, regardless of breast cancer history, did not meet the current USPSTF criteria for lung cancer screening.

Background The Enhanced Recovery After Surgery (ERAS) society lists early mobilization as one of their recommendations for improving patient outcomes following colorectal surgery. The level of supporting evidence, however, is relatively weak, and furthermore, the ERAS guidelines do not clearly define “early” mobilization. In this study, we define mobilization in terms of time to first ambulation after surgery and develop an outcome-based cutoff for early mobilization. Methods This is a retrospective cohort study comprised of 291 patients who underwent colorectal operations at a large, academic medical center from June to December 2019. Three cutoffs (12 hours, 24 hours, and 48 hours) were used to divide patients into early and late ambulation groups for each cutoff, and statistical analysis was performed to determine differences in postoperative outcomes between the corresponding groups. Results Multivariate analysis showed no difference between the early and late ambulation groups for the 12-hour and 48-hour cutoffs; however, ambulation before 24 hours was associated with a decreased rate of severe complications as well as fewer adverse events overall. Patients who ambulated within 24 hours had a 4.1% rate of severe complications and a 22.1% rate of experiencing some adverse event (complication, return to the emergency department, and/or readmission). In comparison, 11.8% of patients who ambulated later experienced a severe complication ( P = 0.026), while 36.1% of patients experienced some adverse event ( P = 0.011). Conclusions Ambulation within 24 hours after colorectal surgery is associated with improved postoperative outcomes, particularly a decreased rate of severe complications.

The incidence of esophagogastric junction (EGJ) adenocarcinoma is increasing worldwide. Management of these tumors remains controversial given their unique location between the esophagus and the stomach. Debate surrounding the optimal therapy for EGJ adenocarcinoma has often centered around the tumor origin as defined by the Siewert classification system. However, the optimal surgical management should focus on adhering to important surgical principles that will allow for the best outcomes and prognosis regardless of tumor location including resection with appropriate and negative histological margins, adequate lymphadenectomy, minimization of morbidity and mortality, and preservation of quality‐of‐life. In this article, we provide a discussion of the controversy surrounding EGJ adenocarcinoma within the framework of these concepts.

OBJECTIVE To improve understanding of sex differences in clinicopathologic characteristics, treatment and outcomes between male and female patients undergoing esophagectomy for esophageal cancer. SUMMARY BACKGROUND DATA Esophageal cancer is a male predominant disease, and sex has not been considered in previous studies as an important factor in diagnosis or management. Sex differences in demographics, clinicopathologic characteristics, and postoperative outcomes remain largely undefined. METHODS Retrospective review of 1958 patients (21% female) with esophageal cancer who underwent esophagectomy at a single institution between 1995 and 2017. RESULTS Most patients had adenocarcinoma (83%); however, the rate of squamous cell carcinoma was significantly higher in females (35% vs 11%, respectively; P

Objective We sought to evaluate the performance of two commonly used prediction models for postoperative morbidity in patients undergoing open and minimally invasive esophagectomy. Summary background data Patients undergoing esophagectomy have a high risk of postoperative complications. Accurate risk assessment in this cohort is important for informed decision-making. Methods We identified patients who underwent esophagectomy between January 2016 and June 2018 from our prospectively maintained database. Predicted morbidity was calculated using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator (SRC) and a 5-factor NSQIP-derived frailty index. Performance was evaluated using concordance index (C-index) and calibration curves. Results In total, 240 consecutive patients were included for analysis. Most patients (85%) underwent Ivor Lewis esophagectomy. The observed overall complication rate was 39%; the observed serious complication rate was 33%. The SRC did not identify risk of complications in the entire cohort (C-index, 0.553), patients undergoing open esophagectomy (C-index, 0.569), or patients undergoing minimally invasive esophagectomy (C-index, 0.542); calibration curves showed general underestimation. Discrimination of the SRC was lowest for reoperation (C-index, 0.533) and highest for discharge to a facility other than home (C-index, 0.728). Similarly, the frailty index had c-index of 0.513 for discriminating any complication, 0.523 for serious complication, and 0.559 for readmission. Conclusions SRC and frailty index did not adequately predict complications after esophagectomy. Procedure-specific risk-assessment tools are needed to guide shared patient-physician decision-making in this high-risk population.

INTRODUCTION: Pyloric drainage during minimally invasive esophagectomy (MIE) may be more technically challenging than during the open approach and alternatives to the classic surgical drainage approach have increased in popularity. However, data are lacking to demonstrate whether one technique is superior in MIE. The purpose of this study was to compare postoperative outcomes after MIE between different pyloric drainage methods. METHODS: We performed a retrospective review of a prospectively maintained database of patients undergoing MIE at a single academic institution. Patients were divided into three groups for analysis: no drainage, intrapyloric Botulinum Toxin injection, and surgical drainage (pyloroplasty or pyloromyotomy). The primary outcome was any complication within 90 days of surgery; secondary outcomes included reported symptoms and need for pyloric dilation at 6 and 12 months postoperatively. Comparisons among groups were conducted using Kruskal Wallis RESULTS: There were 283 MIE performed between 2011 and 2017; of these, 126 (45%) had drainage (53 Botulinum injection and 73 surgical). No significant difference in the rate of postoperative complications, pneumonia or anastomotic leak was observed between groups. At 6 and 12 months, patients that received Botulinum Toxin and surgical drainage had significantly more symptoms than no drainage (p

Background Induction therapy has not been proven to be beneficial for patients with clinical T2N0 esophageal adenocarcinoma. Surgery alone is associated with disappointing survival for patients found to have nodal disease on final pathologic examination. The aim of this study was to identify factors that predict pathologic nodal involvement in patients with endoscopic ultrasound (EUS)–proven T2N0 esophageal adenocarcinoma. Methods We retrospectively reviewed patients with EUS-staged T2N0 (uT2N0) esophageal adenocarcinoma treated with surgery alone. Final pathologic staging was compared with clinical staging. Demographic and clinicopathologic variables were evaluated as putative risk factors for nodal metastases. Logistic regression models were used to identify factors associated with nodal involvement. Kaplan-Meier analysis was performed to compare overall and recurrence-free survival between patients with (N+) and without (N−) nodal disease. Results We identified 80 patients with uT2N0 esophageal adenocarcinoma treated with surgery alone. Clinical staging with EUS was inaccurate for 73 patients (91%). Twenty-eight patients (35%) had pathologic N+ disease at resection. Five-year overall survival was 67% for N− patients and 41% for N+ patients ( p = 0.006). Recurrence-free survival was 65% for N− patients and 32% for N+ patients ( p = 0.0043). Univariable analysis identified vascular invasion and neural invasion as risk factors for nodal metastasis. Multivariable analysis identified vascular invasion as an independent predictor of pathologic nodal involvement. Conclusions EUS is inaccurate for staging of T2N0 esophageal adenocarcinoma and often fails to identify nodal involvement. Identification of vascular invasion on preoperative biopsy should be explored as a prognostic marker to select patients for induction therapy.

BACKGROUNDS AND AIMS: As treatment for esophageal cancer often involves a multidisciplinary approach, the initial endoscopic report is essential for communication between providers. Several guidelines have been established to standardize endoscopic reporting. This study evaluates the compliance of esophagogastroduodenoscopy (EGD) and endoscopic ultrasound (EUS) reporting with the current national guidelines. METHODS: Combining the National Comprehensive Cancer Network and Society of Thoracic Surgeons guidelines, 11 quality indicators (QIs) for EGD and 8 for EUS were identified. We evaluated initial EGD and EUS reports from our institution (Memorial Sloan Kettering [MSK]) and outside hospitals (OSHs) and calculated individual and overall quality measure scores. Scores between locations were compared using the Wilcoxon signed-rank test and McNemar’s test for paired data. RESULTS: In total, 115 initial EGD reports and 105 EUS reports were reviewed for patients who underwent surgery for esophageal cancer between 2014 and 2016. The median number of QIs reported for the initial EGD was 4 (IQR, 3–6)—only 34% of reports qualified as “good quality” (those with ≥ 6 QIs). None of the reports included all QIs. For patients who underwent EGD at both MSK and an OSH, 32% of reports from OSHs were good quality, compared with 68% from MSK (p < 0.001). Compliance with QIs was better for EUS reports: 71% of OSH reports and 72% of MSK reports were good quality. CONCLUSIONS: Detailed information on the initial endoscopic assessment is essential in today’s age of multidisciplinary care. Identification and adoption of QIs for endoscopic reporting is warranted to ensure the provision of appropriate treatment.

Although opioids are frequently prescribed in the postoperative setting, the call for increased opioid stewardship among surgeons has only recently become more urgent. Recent studies have shown that opioids are overprescribed postoperatively (1,2). Given that the risk of chronic opioid use and consequently, misuse and abuse, has been demonstrated to increase with longer duration and higher dosage prescriptions, it is time for surgeons to have a proactive role in mitigating the opioid crisis (3,4). Most of the current literature to date on postoperative opioid prescribing has focused on general, gynecologic, and orthopedic surgery (1-3,5,6). Opioid prescribing patterns and implications for thoracic surgery remain mostly undefined.

Node dissection during esophagectomy is an important aspect of esophageal cancer staging. Controversy remains as to how many nodes need to be resected in order to properly stage a patient and whether the removal of more nodes carries a stage-independent survival benefit. A review of the literature performed by a group of experts in the subject may help define a minimum accepted number of lymph nodes to be resected in both primary surgery and post-induction therapy scenarios. The existing evidence generally supports the goal of obtaining a minimum of 15 lymph nodes for pathological examination in both primary surgery and post-induction therapy scenarios.

There are limited data regarding optimal surveillance after curative resection for esophageal cancer. Once disease recurrence is diagnosed, the prognosis is poor. The purpose of this article was to characterize disease recurrence in patients with early esophageal adenocarcinoma.Two hundred sixty patients were identified from a prospective institutional database with pathologic T1 and T2 node-negative disease therapy treated with curative esophagectomy alone for esophageal adenocarcinoma between 1995 and 2017. Competing risk analysis was used to analyze factors associated with recurrence.The 5-year cumulative incidence of recurrence was 12%. Predictive factors for increased risk of recurrence included increasing tumor size, poor differentiation, and pathologic T2 disease (P.05), whereas presence of Barrett's esophagus on pathology was protective. Recurrence within 2 years was 2.5%, 6.1%, and 12% for T1a, T1b, and T2 disease, respectively. At 5 years cumulative incidence of recurrence was 8.2%, 11.5% and 22.2%, respectively. Median overall survival after recurrence was 1.04 years (95% confidence interval, 0.7-2.4). There were 14 subclinical and 13 symptomatic recurrences; patients with symptomatic recurrence had a significantly shorter overall survival after recurrence occurred (0.31 vs 0.71 years, P = .018).Among early node-negative patients with esophageal cancer undergoing curative resection, 5-year recurrence was 12%. Survival after recurrence was poor, and only a few patients had isolated locoregional recurrence at time of diagnosis, suggesting that scheduled surveillance may have an important role.

Background Endoscopic mucosal resection (EMR) has emerged as an esophageal-preserving treatment for T1 esophageal adenocarcinoma (EAC); however, only patients with negligible risk of lymph node metastasis (LNM) are eligible. Reliable clinical diagnostic tools for LNM are lacking, as such, several risk assessment scores have been developed. The purpose of this study was to externally validate 2 previously published risk scores (Lee and Weksler) for clinical prediction of LNM in T1 EAC patients. Methods In adherence with the Lee and Weksler scores, esophagectomy patients with pathologic T1 EAC were identified. Sub-analysis was performed in patients with clinical T1 based on EMR. Predictive accuracy of the scores was evaluated by calculating the area under the curve of the receiver operating characteristic curve and calibration plots. The areas under the curves were compared using Venkatraman's test for paired receiver operating characteristic curves. Results Of 233 patients identified who met study criteria for external validation, 3 T1a and 32 T1b patients had LNM. The receiver operating characteristic curves demonstrated comparable high predictive and discriminatory capabilities with areas under the curves of 0.832 and 0.824 for the Lee and Weksler scores, respectively (p = 0.750). Results were more variable for the EMR cohort. Based on the risk thresholds defined by each score, the false-positive rate compared against the pathologic LNM status were 73% and 56% for Lee and Weksler, with 3% false negatives in the latter. On EMR, the false-positive rates were 70% and 50% for Lee and Weksler, with no false negatives. Conclusions Both scoring systems demonstrated good discriminatory ability and predictive accuracy for LNM, but the defined thresholds resulted in a high false-positive rate. A better scoring system based on clinical characteristics is needed to better identify patients with local disease.

Despite high HPV prevalence and low vaccination rates in the military, HPV vaccination is not required upon military service initiation. Given that national HPV vaccination rates remain low among people age 19–26 years, military service may represent an opportune time for intervention. The purpose of this study was to quantify the rate of HPV vaccination among young patients entering primary care at a single Veterans Affairs Medical Center (VAMC). Vaccination rates among veterans age ≤ 26 years old at first primary care visit were identified from the institutional data warehouse. Among 1,258 eligible patients, most were male (n = 782). The HPV vaccine initiation rate was 21.2%. Overall, 10.4% of patients received at least 1 HPV vaccine prior to initiating care at the VA (25.2% females and 1.4% males). An additional 10.8% of patients received their first HPV vaccine upon initiating care at the VA. Median age of first HPV vaccination was 21.4 years among patients that initiated the vaccine in the military versus 24.8 years among those that initiated vaccination at the VA. In conclusion, this study demonstrated low HPV vaccination rates both prior to transitioning to VA primary care and once receiving care at the VA. Additionally, among veterans that had not received vaccination upon initiating care at the VA, older age at vaccination was observed. Older age at vaccination may reduce HPV vaccine effectiveness given higher risk of exposure. Addition of HPV to the list of mandated vaccines upon military service initiation should be considered.

This chapter examines the etiology, diagnostic techniques, and treatment approaches of anastomotic complications after esophagectomy. An understanding of these much feared events may help mitigate the impact of the associated negative clinical sequelae. Anastomotic leak has a wide variation in presentation, from an incidental radiologic finding to a catastrophic septic event. Patients should be adequately resuscitated, and further management is dependent upon the location of the leak and clinical presentation. Mild cases may be observed or managed with local drainage. The most severe cases are conduit necrosis. In suspected cases, direct visualization of the conduit is necessary, and subsequent resection must be performed if the diagnosis is confirmed. Anastomotic leak is a frequent cause of anastomotic stricture; however, later presentation must raise suspicion for tumor recurrence. In benign cases, endoscopic dilation is often sufficient. Leaks are also a frequent cause of conduit airway fistulas. Such events are rare but are life threatening and must rapidly be identified. In such cases, a trial of conservative treatment may be pursued with subsequent endoscopic therapy and, ultimately, surgical resection if this is not successful.

Highlights • Foreign body ingestion is a rare cause of appendicitis. • Heavy, rigid, long, or sharp objects are more likely to lodge within the appendix. • Laparoscopic appendectomy should be performed for foreign body appendicitis to ameliorate the risk of complications., Introduction Foreign body ingestion is an uncommon clinical problem in healthy adults. Furthermore, it is even less common for an ingested foreign body to cause any obstructive symptoms within the gastrointestinal tract. Presentation of case Here, we describe an unusual case of acute appendicitis induced by a tongue piercing that was ingested by a 32-year-old woman with a recent history of endotracheal intubation. Abdominal X-ray revealed metallic foreign bodies in the right lower quadrant. The foreign bodies remained in place on serial X-rays despite bowel preparation and they were not visualized on colonoscopy. Computed tomography (CT) of the abdomen and pelvis confirms the location of the foreign body within the appendix. Laparoscopic appendectomy was performed without complications and the tongue piercing was recovered within the lumen of the resected appendix. Discussion Foreign body ingestion is a rare cause of appendicitis. Most ingested foreign bodies spontaneously pass through the gastrointestinal tract within a week. However, in rare instances, the foreign body becomes lodged in the appendix, often resulting in appendicitis. Conclusion In patients with appendicitis secondary to foreign body ingestion, we suggest surgical management to reduce the risk of peritonitis, perforation, and abscess formation.

Background COVID-19 patients requiring mechanical ventilation may develop significant pneumomediastinum and sub-cutaneous emphysema without associated pneumothorax (SWAP). Prophylactic chest tube placement or sub-fascial "blowholes" are usually recommended to prevent tension pneumothorax and clinical decline. Risk of iatrogenic lung injury and release of virus into the environment is high. Incidence and conservative management data of such barotraumatic complications during the COVID-19 pandemic are lacking. Methods All patients with mediastinal air and SWAP evaluated by the department of Thoracic Surgery at the Mount Sinai Hospital between March 30 and April 10, 2020 were identified. All patients without pneumothorax were treated conservatively with daily chest x-ray and observation. Three patients had prophylactic chest tube placement prior to the study period without thoracic surgery consultation. Results There were 29 cases of mediastinal air with SWAP out of 171 COVID positive intubated patients (17.0%) who were treated conservatively. Patients were intubated for an average of 2.4 days before SWAP was identified. 12 patients (41%) had improvement or resolution without intervention. Two patients progressed to pneumothorax 3 and 8 days following initial presentation. Both had chest tubes placed without incident before there were any changes in oxygenation, hemodynamics, supportive medications, or ventilator settings. There were 3 patients who had percutaneous tubes placed before the study period all of whom had significant worsening of their sub-cutaneous air and air leak. Conclusions Conservative management of massive sub-cutaneous emphysema without pneumothorax in COVID-19 patients is safe and limits viral exposure to healthcare workers. Placement of chest tubes is discouraged unless a definite sizable pneumothorax develops.

341 Background: Resection is the best treatment for both esophagus and lung cancer, however, concerns that a combined resection of synchronous lung/esophagus tumors might be associated with higher morbidity may preclude surgical therapy. We sought to review a multi-institutional experience on combined esophagus/lung cancer resections. Methods: Patients undergoing esophagectomy and those with concurrent anatomic resection for bronchogenic carcinoma between 1997-2018 at three high-volume North American centers were identified from prospectively collected databases. Combined resection cases (E+L) were matched in a 1:3 ratio to patients who underwent esophagectomy alone (E), based on age, sex, stage, neoadjuvant therapy, procedure (2/3hole), and approach (MIE/open). Patient demographics, tumour characteristics, and post-operative outcomes were compared. Statistical analysis was performed using unpaired t-test or Wilcoxon sum-rank test for continuous variables and Fisher’s exact test for categorical data. Statistical significance was defined as p < 0.05. Results: Of over 2500 patients undergoing esophagectomy, synchronous anatomic lung resection was performed in 20; 4 were excluded due to incomplete data (n = 16). Matching yielded 48 patients and 4 duplicates were removed (n = 44); there were no significant differences in patient demographics, neoadjuvant therapy, clinical stage, or procedure. Anatomic resection consisted of lobectomy (16/20), segmentectomy (3/20) and pneumonectomy (1/20), combined with 2-hole (14/20), 3-hole (4/20), or left thoraco-abdominal (2/20) esophagectomy. The proportion of patients with any complication in E+L was 50%, and 66% in E (p = 0.42). Pulmonary complications were 19% and 27% in the respective groups (p = 0.74). Mortality did not differ (E+L = 0/16:E = 1/44)NS. The median length of stay for both groups was similar (E+L = 10.5 days(IQR 5.7): E = 10.0 days (IQR 8.7))NS. Conclusions: Patients with synchronous localized lung and esophageal cancer, although rare, should not be biased towards non-surgery therapy, as the morbidity associated with combined esophagectomy and anatomic lung resection does not differ significantly from esophagectomy alone.

The 2011 National Comprehensive Cancer Network guidelines first incorporated the results of the landmark CROSS trial, establishing induction therapy (chemotherapy ± radiation) and surgery as the treatment standard for locoregional esophageal cancer in the United States. The effect of guideline publication on socioeconomic status (SES) inequalities in cancer treatment selection remains unknown. Patients diagnosed with Stage II/III esophageal cancer between 2004 and 2013 who underwent curative treatment with definitive chemoradiation or multimodality treatment (induction and surgery) were identified from the Surveillance, Epidemiology and End Results (SEER)-Medicare registry. Clinicopathologic characteristics were compared between the two therapies. Multivariable regression analysis was used to adjust for known factors associated with treatment selection. An interaction term with respect to guideline publication and SES was included Of the 2,148 patients included, 1,478 (68.8%) received definitive chemoradiation and 670 (31.2%) induction and surgery. Guideline publication was associated with a 16.1% increase in patients receiving induction and surgery in the low SES group (21.4% preguideline publication vs. 37.5% after). In comparison, a 4.5% increase occurred during the same period in the high SES status group (31.8% vs. 36.3%). After adjusting for factors associated with treatment selection, guideline publication was associated with a 78% increase in likelihood of receiving induction and surgery among lower SES patients (odds ratio 1.78; 95% confidence interval (CI): 1.05,3.03). Following the new guideline publication, patients living in low SES areas were more likely to receive optimal treatment. Increased dissemination of guidelines may lead to increased adherence to evidence-based treatment standards.

Background Recurrence of esophageal cancer in the brain is rare but associated with a poor prognosis. Identification of risk factors for isolated brain metastasis of esophageal cancer (iBMEC) after surgical treatment may guide surveillance recommendations to enable early identification and intervention before widespread metastasis. Methods Patients with iBMEC (n = 38) were identified from a prospective database of patients with esophageal cancer who underwent esophagectomy. Risk factors for iBMEC were identified using competing risk regression analysis. Results In a cohort of 1760 patients, 39% recurred and iBMEC developed in 2% by the end of the study. Survival in patients with iBMEC was similar to survival in patients with distant recurrence (median overall survival, 0.95 years; 95% confidence interval, 0.6-1.5 years). More than half of patients with iBMEC were diagnosed within 1 year postoperatively. All 38 patients with iBMEC had received neoadjuvant therapy before surgery. Pathologic complete response (PCR) to neoadjuvant therapy was associated with improved survival after brain recurrence (median overall survival, 1.56 vs 0.66 years; P = .019). Conclusions In patients with PCR, iBMEC may represent true isolated recurrence, whereas in those with residual nodal disease, iBMEC may actually be the first observed site of widespread metastasis. Patients who receive neoadjuvant therapy, especially with PCR, may benefit from brain imaging, both preoperatively and with routine surveillance.

Background Esophageal cancer is considered a disease of the elderly. Although the incidence of esophageal adenocarcinoma in young patients is increasing, current guidelines for endoscopic evaluation of gastroesophageal reflux disease and Barrett's esophagus include age as a cutoff. There is a paucity of data on the presentation and treatment of esophageal cancer in young patients. Most studies are limited by small sample sizes, and conflicting findings are reported regarding delayed diagnosis and survival compared with older patients. Methods A retrospective cohort study was performed using the National Cancer Database between 2004 and 2015. Patients with esophageal adenocarcinoma were divided into quartiles by age (18-57, 58-65, 66-74, 75+ years) for comparison. Clinicopathologic and treatment factors were compared between groups. Results A total of 101,596 patients were identified with esophageal cancer. The youngest patient group (18-57 years) had the highest rate of metastatic disease (34%). No difference in tumor differentiation was observed between age groups. Younger patient groups were more likely to undergo treatment despite advanced stage at diagnosis. Overall 5-year survival was better for younger patients with local disease, but the difference was less pronounced in locoregional and metastatic cases. Conclusions In this study, young patients were more likely to have metastatic disease at diagnosis. Advanced stage in young patients may reflect the need for more aggressive clinical evaluation in high-risk young patients.

OBJECTIVE: Esophageal squamous cell carcinoma (ESCC-R) is a rarely encountered sequela of chest radiation. Treatment is limited by toxicity with reirradiation and complex surgical dissection in a previously radiated field. The clinical presentation, prognosis and treatment selection of ESCC-R remains undefined. METHODS: A retrospective review was performed of patients with esophageal squamous cell carcinoma at a single institution between 2000 to 2017 to identify patients with previous radiation therapy (≥ 5 years delay). Clinicopathologic characteristics, treatment and outcomes of ESCC-R (n=69) patients were compared to patients with primary esophageal squamous cell carcinoma (ESCC) (n=827). Overall survival (OS) and cumulative incidence of recurrence (CIR) were compared using log rank and Gray’s tests, respectively. RESULTS: Median time from radiation to ESCC-R was 18.2 years. The majority of ESCC-R patients was female, and presented with earlier disease and decreased behavioral risk factors. ESCC-R treated with surgery alone had worse OS than ESCC (5-year 15% vs 33, p=0.045). Patients with ESCC-R that received neoadjuvant treatment had higher risk of postoperative in-house mortality (16.7% vs 4.2, p=0.032). Patients with ESCC-R treated with surgery alone and definitive chemoradiation had higher recurrence risk than neoadjuvant+surgery (5-year recurrence 55% and 45 vs 15%, p=0.101). CONCLUSION: Neoadjuvant chemotherapy or chemoradiation should be used whenever possible for ESCC-R as it is associated with lower risk of recurrence. The improved survival benefits of aggressive treatment must be weighed against the higher associated postoperative risks.

Neoadjuvant therapy has been demonstrated to improve overall (OS) and disease-free survival (DFS) in patients undergoing surgical resection for locally advanced esophageal cancer. Restaging after treatment has an important role in therapeutic decision-making and determining patient prognosis. Available methodologies most often utilize a combination of endoscopy and imaging in characterization of treatment response. While endoscopic ultrasound (EUS) is routinely used in initial staging, resultant inflammation and fibrosis after treatment challenges the utility of this modality in restaging. Endoscopic biopsy similarly has a limited benefit in the assessment of treatment response. Change in metabolic response on 18-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG- PET/CT) on pre- and post-treatment imaging has been demonstrated may help predict tumor regression, and consequently, patient survival. Adoption of an approach utilizing FDG-PET response to adjust neoadjuvant chemotherapy has been observed to result in an increase in the rate of pathologic complete response (pCR) and progression-free survival. Current diagnostic tools enable differentiation between responders versus nonresponders to neoadjuvant therapy; however, they remain limited in their ability to identify therapeutic response.

Background Multivisceral resection is often required in the treatment of locally advanced rectal cancers. Such resections are relatively rare and oncologic outcomes, especially when sphincter preservation is performed, are not fully demonstrated. Methods A retrospective review was conducted of patients who underwent multivisceral resection for locally advanced rectal cancer with and without sphincter preservation. Results Sixty-one patients underwent multivisceral resection for rectal cancer from 2005 to 2013 with a median follow-up of 27.8 months. Five-year overall and disease-free survival were 49.2% and 45.3%, respectively. Thirty-four patients (55.7%) had sphincter-sparing operations with primary coloanal anastomosis and temporary stoma. There was no significant difference in overall or disease-free survival, or recurrence with sphincter preservation compared with those with permanent stoma. Conclusions Multivisceral resection for locally advanced rectal cancer has acceptable oncologic and clinical outcomes. Sphincter preservation and subsequent reestablishment of gastrointestinal continuity does not impact oncologic outcomes and should be considered in many patients.

As the evidence supporting the value of well-coordinated healthcare teams continues to grow, so to do the calls from medical educators and policy makers for the development of meaningful interprofessional educational experiences for health professions students. The student-run clinic has emerged as a unique venue for such experiential interprofessional learning experiences, with over 100 such clinics now in operation across North America. As the number and variety of these clinics rises, it has become increasingly important to understand the quality of care which they deliver. Here, patient satisfaction data from an interprofessional student-run free clinic are described, and these results are quantitatively compared to similar data obtained from a non-interprofessional, non-student-run clinic in a post-experience only, non-equivalent groups design. Student-run free clinic patients reported high levels of satisfaction with the patient care team and the facility quality, and lower levels of satisfaction with waiting times. When compared to the non-student-run clinic, there was no significant difference in the high levels of patient satisfaction with the patient care teams between the clinics. Student-run free clinic patients did, however, report significantly lower levels of satisfaction with the accessibility of care and with the perceived privacy of protected health information. Overall, this report provides evidence that an interprofessional student-run free clinic is capable of performing at the level of an experienced free clinic across many domains of patient satisfaction, while also identifying notable areas for improvement within the domains of clinic accessibility and the perception of the privacy of protected health information.

Background The aim of this study was to assess the difference (Δ) in neutrophil to lymphocyte ratio (NLR), before and after chemoradiotherapy, as a predictor of treatment response and a prognostic factor for recurrence and disease-free survival in patients with esophageal squamous cell cancer treated with chemoradiotherapy with or without surgery. Methods Patients with locally advanced esophageal squamous cell cancer treated with chemoradiation with and without surgery who had a complete blood count before and after chemoradiotherapy were included. Pretreatment and posttreatment NLR were calculated by dividing the absolute neutrophil count by the absolute lymphocyte count. The ΔNLR was defined as posttreatment minus pretreatment NLR. Characteristics were evaluated for association with ΔNLR using the Wilcoxon signed rank test or the Kruskal-Wallis test. Risk of recurrence and disease-free survival were evaluated using Gray’s and the log rank tests, respectively. Results We included 217 patients. Of them, 133 patients (61.3%) received only chemoradiotherapy and 84 (38.7%) underwent surgery after chemoradiotherapy. Among the surgical patients, 43% with pathologic complete response showed significantly lower median ΔNLR than patients with residual disease (−0.03 versus 1.04, p = 0.004). High ΔNLR was a negative predictor of treatment response (odds ratio 0.77, 95% confidence interval: 0.62 to 0.9, p = 0.004). A significant association between high ΔNLR and increased risk of recurrence was also identified. Conclusions The ΔNLR was inversely related to pathologic complete response and associated with risk of recurrence. This simple test, in concert with other clinical tools, can help identify patients with pathologic complete response.

Despite laparoscopy and enhanced recovery pathways, some patients do not attain early discharge. Frailty is generally accepted as a marker of increased risk, complications, and mortality. Frailty may have the potential to identify patient outcomes.The aim of this study was to evaluate frailty as a predictor of patients who might fail early discharge.This study was conducted at a tertiary referral center.This was a case-matched study.Elective abdominal laparoscopic colorectal cases from 2009 to 2012 were selected.Review of a prospective database matched all cases with a postoperative day of discharge of ≤3 days to a3 day of discharge cohort. All patients followed a standardized enhanced recovery pathway.Categorical and ordinal variables were analyzed with the Student t test or Fisher exact test, and correspondence analysis evaluated the relationship between length of stay and the Modified Frailty Index.The primary outcome measure was the relationship between length of stay and the Modified Frailty Index.There were 464 ≤3 day and 3883 day patients. The groups were similar in demographics and comorbidities. There were significant differences in the Modified Frailty Index (p0.01), operative time (p0.01), postoperative complications (p0.01), 30-day readmissions (p = 0.03), and 30-day reoperation rate (p0.01). Significantly more patients were discharged home in the ≤3 day cohort. Correspondence analysis demonstrated a higher Modified Frailty Index was indicative of longer length of stay. A Modified Frailty Index of 0 was strongly related to a length of stay 0 to 3 days, and a Modified Frailty Index of 2 was strongly related to a 8- to 14-day stay.This was a single-center study performed on a retrospective data set.Patients undergoing elective colorectal surgery with a higher Modified Frailty Index were more likely not to attain early discharge. Despite similar demographics, the Modified Frailty Index could discriminate between patient outcomes, and correlated with longer operating times, length of stay, and readmissions. By using a prospective score to identify patients at risk for not achieving early discharge preoperatively, resources and postoperative support can be better allocated.

Background The surgical indications for symptomatic rectocele are undefined, and surgery has high recurrence rates. We implemented magnetic resonance imaging defecography (MRID) to determine if utilizing strict inclusion criteria for rectocele repair improves outcomes. Methods Patients with obstructive defecation syndrome (ODS) who underwent dynamic MRID were evaluated. Indications for surgical repair were defecation requiring manual assistance and the following MRID results: anterior defect >2 cm, incomplete evacuation, and the absence of perineal descent. Primary outcomes were the change in quality of life (QOL) scores and recurrence. Results From 2006 to 2013, 143 patients who presented with ODS underwent MRID. Seventeen patients met the criteria for repair. Recurrence was low (5.8%) with a median follow-up of 23 months, QOL scores improved from 57.3 to 76.5 ( P = .041). Conclusions A minority of patients (12%) with ODS met the above criteria for rectocele repair. Patients who underwent repair had a significant improvement in QOL and low recurrence rate.

Background Endoscopic resection has emerged as an esophageal-preserving treatment for T1 esophageal adenocarcinoma (EAC); however, only patients with negligible risk of nodal metastasis should receive this option. Since preoperative reliable diagnostic tools are lacking, scoring systems have been developed to assess risk of lymph node metastasis (LNM). The purpose of this study was to provide external validation of two previously published scoring systems for clinical prediction of nodal status in patients with T1 EAC. Methods In adherence with patient selection criteria in the two previously published scoring systems (figure 1), we identified patients with T1 EAC (n = 230) who underwent esophagectomy without neoadjuvant treatment from a prospective database between 1995 and 2017. Clinicopathologic characteristics were compared between patients with LNM and without. Risk scores were tabulated in accordance with the two scoring systems. Predictive accuracy of the scores were evaluated by c-index and calibration plots, and compared using Venkatraman's test for paired receiver operating characteristics curves. Results Groups were similar in age, location and nodes harvested. There were 38 (17%) patients with positive LNM; 3/66 (5%) T1a and 35/164 (21%) T1b. LNM was associated with poor differentiation (25% vs 42; P = 0.001), positive LVI (16.1% vs 71.1; P Conclusion Both scoring systems demonstrated good predictive accuracy for LNM; however, B may be simpler to implement. Most patients classified as high risk or for esophagectomy did not have nodal metastasis on pathology. Future scoring systems must better identify which patients are candidates for organ preservation on the basis of LNM. Disclosure All authors have declared no conflicts of interest.
