Clinical T2 N0 M0 Esophageal Cancer: Identifying Predictive Factors of Upstaging. Ann Thorac Surg 2024; 117:1121-1127. [PMID: 38307482 DOI: 10.1016/j.athoracsur.2024.01.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 01/03/2024] [Accepted: 01/15/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND Inaccuracy of clinical staging renders management of clinical T2 N0 M0 (cT2 N0 M0) esophageal cancer difficult. When an underlying advanced-stage disease is understaged to cT2 N0 M0, patients miss the opportunity to gain the potential benefits of neoadjuvant therapy. This study aimed to identify preoperative factors that predict underlying advanced-stage esophageal cancer. METHODS From 2000 to 2020, 1579 patients with esophageal cancer underwent esophagectomy. Sixty patients who underwent upfront surgery for cT2 N0 M0 esophageal cancer were included in this study. The median age was 62.5 years, and 78% (n = 47) of these patients were male. Radiologic, clinical, and endoscopic factors were evaluated as preoperative markers. The Fisher exact and the Wilcoxon rank sum tests were used for categoric and continuous variables, respectively. Random forest classification was used to identify preoperative factors for predicting upstaging and downstaging. RESULTS Of the 60 patients, 8 (13%) were found to have pathologic T2 N0 M0 esophageal cancer. Sixteen (27%) patients had cancer that was pathologically downstaged, and 36 (60%) had upstaged disease. Seven (19%) patients had upstaged cancer on the basis of the pathologic T stage, 14 (39%) had upstaging on the basis of the pathologic N stage, and 15 (42%) had upstaging on the basis of both T and N stages. Dysphagia (P = .003) and tumor maximum standardized uptake value (P = .048) were predictors of upstaging, with a combined predictive value of up to 75%. CONCLUSIONS The presence of dysphagia and of high maximum standardized uptake value (≥5) of the tumor is predictive of more advanced underlying disease for patients with cT2 N0 M0 esophageal cancer, and these patients should be considered for neoadjuvant therapy.

Quant Imaging Med Surg 2023; 13:7996-8008. [PMID: 38106287 PMCID: PMC10722054 DOI: 10.21037/qims-23-275] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 10/11/2023] [Indexed: 12/19/2023]
Abstract
Background Predicting preoperative understaging in patients with clinical stage T1-2N0 (cT1-2N0) esophageal squamous cell carcinoma (ESCC) is critical to customizing patient treatment. Radiomics analysis can provide additional information that reflects potential biological heterogeneity based on computed tomography (CT) images. However, to the best of our knowledge, no studies have focused on identifying CT radiomics features to predict preoperative understaging in patients with cT1-2N0 ESCC. Thus, we sought to develop a CT-based radiomics model to predict preoperative understaging in patients with cT1-2N0 esophageal cancer, and to explore the value of the model in disease-free survival (DFS) prediction. Methods A total of 196 patients who underwent radical surgery for cT1-2N0 ESCC were retrospectively recruited from two hospitals. Among the 196 patients, 134 from Peking University Cancer Hospital were included in the training cohort, and 62 from Henan Cancer Hospital were included in the external validation cohort. Radiomics features were extracted from patients' CT images. Least absolute shrinkage and selection operator (LASSO) regression was used for feature selection and model construction. A clinical model was also built based on clinical characteristics, and the tumor size [the length, thickness and the thickness-to-length ratio (TLR)] was evaluated on the CT images. A radiomics nomogram was established based on multivariate logistic regression. The diagnostic performance of the models in predicting preoperative understaging was assessed by the area under the receiver operating characteristic curve (AUC). Kaplan-Meier curves with the log-rank test were employed to analyze the correlation between the nomogram and DFS. Results Of the patients, 50.0% (67/134) and 51.6% (32/62) were understaged in the training and validation groups, respectively. The radiomics scores and the TLRs of the tumors were included in the nomogram. The AUCs of the nomogram for predicting preoperative understaging were 0.874 [95% confidence interval (CI): 0.815-0.933] in the training cohort and 0.812 (95% CI: 0.703-0.912) in the external validation cohort. The diagnostic performance of the nomogram was superior to that of the clinical model (P<0.05). The nomogram was an independent predictor of DFS in patients with cT1-2N0 ESCC. Conclusions The proposed CT-based radiomics model could be used to predict preoperative understaging in patients with cT1-2N0 ESCC who have undergone radical surgery.

Abstract
INTRODUCTION This study was conducted to elucidate the link between adjuvant radiotherapy and survival in pathologic node-negative (pN0) esophageal cancer patients with upfront esophagectomy. METHODS From 2000 to 2016, patients with pN0 esophageal cancer who underwent upfront esophagectomy were selected from the Surveillance, Epidemiology, and End Results (SEER) database. The association of high-risk covariates with survival after adjuvant radiotherapy was evaluated using propensity score matching and multivariate analysis. RESULTS We identified 3197 patients, 321 (10.0%) underwent postoperative radiotherapy and 2876 (90.0%) underwent esophagectomy alone. In the unmatched cohort, postoperative radiotherapy was associated with a statistically significant but modest absolute decrease in survival outcomes (P < 0.001). In the matched cohort, the survival differences disappeared. Additionally, adjuvant radiotherapy was linked to a 5-year overall survival (OS) benefit for patients with the pT3-4N0 disease (34.8% vs. 27.7%; P = 0.008). Adjuvant radiotherapy for pT3-4N0 disease with tumor length ≥3 cm, adenocarcinoma, and evaluated lymph node count <12 was shown to independently function as a risk factor for improved OS, as per a multivariate analysis (P < 0.01). CONCLUSIONS This population-based trial showed that high-risk patients with pT3-4N0 esophageal cancer had better OS following upfront esophagectomy followed by radiotherapy therapy. This discovery may have major significance in the use of adjuvant radiotherapy following upfront esophagectomy in patients with pN0 esophageal cancer.

Abstract
This study analyzed the impact of factors affecting overall survival in patients with pT2N0M0 esophageal squamous carcinoma (ESCC) and developed a nomogram to predict overall survival (OS). We reviewed the clinical data of 413 patients with pathological T2N0M0 ESCC after radical esophagectomy in two hospitals. Data from one institution was used as the training cohort. A nomogram was established using Cox proportional hazard regression for identifying the prognostic factors affecting for OS in ESCC patients. The area under the curve (AUC), calibration curves and decision curve analysis (DCA) were used to evaluate prognostic efficacy, which was validated in an independent validation cohort. In the training cohort (N = 304), the median OS was 69.33 months, and the 3-, 5- and 10-year OS rates were 76.80%, 67.00% and 56.90%, respectively. The median OS of the validation cohort (N = 109) was 73.50 months, and the 3-, 5- and 10-year OS rates were 77.00%, 67.80% and 55.60%, respectively. According to Cox univariate and multivariate analyses, sex, age, tumor length and the number of resected lymph nodes were identified as predictors of OS. We developed nomograms and performed internal and external validation. The time-dependent receiver operating characteristic (ROC) curve and area under the curve (AUC) value, calibration curve and decision curve analysis (DCA) showed good prediction ability of the nomogram. The developed nomogram can effectively predict OS after esophagectomy in patients with pT2N0M0 ESCC.

Abstract
Summary
Background
In the last two decades, both treatment options and epidemiological features of cancer have changed. We studied the influence of related parameters on the outcome of patients undergoing resection for esophageal carcinoma.
Methods
We analyzed 499 consecutive patients who underwent esophagectomy for carcinoma since January 2000, comparing 2000–2010 with 2011–2021 and examining changes over time.
Results
The percentage of men (87.9 vs. 86.9%; p = 0.74) in the two groups was unchanged, whereas mean age increased significantly from 60.8 to 65.2 years (p = 0.000). There was a trend towards an increase of adenocarcinoma (gamma = 0.120, ASE = 0.055). Despite significantly increasing use of induction chemoradiotherapy (p = 0.000) from 7.14% in 2000 to 68.9% in 2021 the distribution of pT, pN stage, grading and the rate of positive lateral resection margins remained unchanged. When comparing the two periods, the overall 30-day mortality was 4.4 vs. 4.2% (p = 0.56), recurrence-free survival was 36.9 vs. 38% at 60 months and 33.9 vs. 36.4% at 120 months (p = 0.93). Tumor-associated survival was 41.1 vs. 45% at 60 months and 35.5 vs. 38.7% at 120 months (p = 0.78). None of the survival rates differed significantly. A multivariable analysis of year of surgery, age, sex, histological subtype, grading, pT, pN, lateral resection margin, and induction therapy showed that only higher pT (p = 0.01), positive pN (p = 0.000), positive lateral margin (p = 0.003), squamous cell carcinoma (p = 0.04) and higher grading (p = 0.026) had a statistically significant, independent, negative influence on prognosis.
Conclusion
Optimized noninvasive and invasive therapeutic modalities have produced only marginal improvement in the prognosis of esophageal cancer within the last two decades.

Abstract
Background Neoadjuvant therapy followed by surgery is recommended for locally advanced esophageal cancer. With the inaccuracies of clinical staging particularly for cT1N+ and cT2Nany tumors, some have proposed consideration of surgery followed by adjuvant treatment. Our objective is to evaluate the efficacy of neoadjuvant therapy vs surgery followed by adjuvant therapy, and to identify the ideal sequence of treatment in patients with cT1N+ and cT2Nany tumors. Methods We performed an analysis utilizing the National Cancer Database (2006-2015) identifying all patients with cT1N+ and cT2Nany esophageal cancer undergoing esophagectomy. The treatment was stratified as: neoadjuvant therapy (NT), adjuvant therapy (AT) and combination therapy of neoadjuvant and adjuvant (CT) groups and outcomes were analyzed. Results We identified 2795 patients with 81.9% (n=2289) receiving NT, 10.2% (n=285) AT, and 7.9% (n=221) CT. There were no significant differences noted in survival among AT, NT, and CT group in cT1N+(P=0.376), cT2N-(P=0.436), cT2N+(P=0.261) esophageal cancer by multivariate analysis using Cox regression model. This relationship held true in both squamous cell carcinoma and adenocarcinoma. Conclusion In clinical T1N+, T2Nany patients, there was no evident superiority of NT over AT. Surgery followed by adjuvant therapy can be considered to be an alternative option in these patients. Further prospective studies are needed to validate these findings.

Abstract
Background In patients with resectable esophageal adenocarcinoma (EAC), the decision for neoadjuvant treatment depends on clinical staging with endoscopic ultrasound (EUS) and positron-emission tomography (PET) scan. Patients with locally advanced EAC pathology misclassified as early EAC by clinical staging are missing the opportunity to receive neoadjuvant therapy. We aim to identify predictors of locally advanced pathology in EAC to determine more accurately those who benefit from neoadjuvant therapy. Methods Retrospective study of patients who underwent upfront endoscopic or surgical resection for EAC without neoadjuvant therapy from January 2011 to December 2017 was performed. Clinical characteristics, EUS, PET scan and histologic findings were analyzed. Multivariable analysis of predictors of locally advanced stage was performed and a risk prediction score was developed. Results A total of 97 patients were included; 68 patients were staged as early EAC (pT1 or pT2 and pN0) and 29 patients were staged as locally advanced EAC (pT1 or pT2 with pN1 and pT3 or pT4 irrespective of N status). In a predictive model of EAC, patients presenting with dysphagia, tumor size >2 cm, exophytic mass appearance on endoscopy and absence of hiatal hernia were more likely to be have locally advanced pathology with a probability of 70% (C-statistic 0.766). Conclusions A risk prediction model based on the presence of dysphagia, tumor size >2 cm, exophytic mass appearance and absence of hiatal hernia can be used to identify locally advanced pathology in EAC patients.

Abstract
BACKGROUND Staging is inaccurate for cT2N0 esophageal cancer, and patients often are clinically mis-staged. This study aimed to evaluate the outcome after upfront surgery or neoadjuvant therapy, considering the impact of clinical "mis-staging." METHODS This study reviewed patients with squamous cell carcinoma (SCC) or adenocarcinoma (ADK) of the esophagus who underwent upfront surgery (S group) or neoadjuvant treatment (chemoradiotherapy [CRT] group) for cT2N0 cancer. Overall survival (OS), disease-free survival (DFS), morbidity, and mortality were evaluated. Correctly staged (cTNM = pTNM), understaged (cTNM < pTNM), and overstaged (cTNM > pTNM) patients in the S group and the CRT group were analyzed. Risk factors for unexpected lymph-node involvement were identified in the S group and for cancer-related death in the whole study cohort. RESULTS The study enrolled 229 patients with cT2N0 esophageal cancer. The 5-year OS rate was 34.2% in the S group versus 55.7% in the CRT group (p = 0.0088). The DFS also was significantly higher (p = 0.01). The morbidity and mortality rates were similar. In the S group, the cTNM was correctly staged for 21.4% and understaged for 63.4% of the patients, with 48.7% of the patients showing unexpected nodal involvement. A tumor length of 3 cm or more was an independent predictor of nodal metastases in SCC (p = 0.03), as was lymphovascular invasion (LVI) in ADK (p < 0.01). Cancer-related mortality was independently associated with lymph-node metastases (p = 0.03) and treatment by upfront surgery (p = 0.01). CONCLUSION Given the high rate of understaged patients in this study (63.4%), the authors advocate for combining the induction therapy with surgery in cT2N0, achieving better survival with similar morbidity and mortality.

Abstract
OBJECTIVE We developed and validated a nomogram predicting the likelihood of occult lymph node metastases in surgically resectable esophageal cancers. BACKGROUND Patients with esophageal cancer with positive lymph nodes benefit from neoadjuvant therapy, but limitations in current clinical staging techniques mean nodal metastases often go undetected preoperatively. METHODS The National Cancer Database was queried for patients with clinical T1-3N0M0 cancer undergoing upfront esophagectomy from 2004 to 2014. Multivariable logistic regression was used to develop the risk model using both statistical significance and clinical importance criteria for variable selection. Predictive accuracy was assessed and bootstrapping was used for validation. A nomogram was constructed for presentation of the final model. RESULTS Of 3186 patients, 688 (22%) had pathologic lymph node involvement (pN+) and 2498 (78%) had pN0 status. Variables associated with pN+ status included histology [adenocarcinoma vs squamous: odds ratio (OR) 1.75], tumor stage (T1: reference, T2: OR 1.90, T3: OR 2.17), tumor size (<1 cm: reference, 1-2 cm: OR 2.25, 2-3 cm: OR 3.82, 3-4 cm: OR 5.40, 4-5 cm: OR 5.66, ≥5 cm: OR 6.02), grade (1: reference, 2: OR 2.62, 3: OR 4.39, 4: OR 4.15, X: OR 1.87), and presence of lymphovascular invasion (absent: reference, present: OR 4.70, missing: OR 1.87), all P < 0.001. A nomogram with these variables had good predictive accuracy (Brier score: 0.14, calibration slope: 0.97, c-index: 0.77). CONCLUSIONS We created a nomogram predicting the likelihood of pathologic lymph node involvement in patients with esophageal cancer who are clinically node negative using a generalizable dataset. Risk stratification with this nomogram could improve delivery of appropriate perioperative care.

Neoadjuvant radiotherapy for locoregional Siewert type II gastroesophageal junction adenocarcinoma: A propensity scores matching analysis. PLoS One 2021; 16:e0251555. [PMID: 33979405 PMCID: PMC8115852 DOI: 10.1371/journal.pone.0251555] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Accepted: 04/27/2021] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE To analyze the effect of neoadjuvant radiotherapy (nRT) on prognosis in patients with locoregional Siewert type II gastroesophageal junction adenocarcinoma (GEA). METHOD All patients pathologically diagnosed as Siewert type II GEA between 2004 and 2015 were retrieved from the Surveillance, Epidemiology and Final Results (SEER) database. We analyzed the impact of different treatment regimens on the prognosis in each stage. Survival analysis was performed by Kaplan-Meier (K-M) method. Multivariate Cox model and propensity score matching was further used to verify the results. RESULTS 4,160 patients were included in this study. The efficacy of nRT was superior to that of adjuvant radiotherapy (aRT) (p = 0.048), which was the same as that of surgery combined with chemotherapy (p = 0.836), but inferior to the overall survival (OS) of surgical treatment alone (p<0.001) in T1-2N0M0 patients. Patients receiving nRT had distinctly better survival than those receiving surgical treatment alone (p = 0.008), but had similar survival compared with patients treated with aRT (p = 0.989) or surgery combined with chemotherapy (p = 0.205) in the T3N0/T1-3N+M0 subgroup. The efficacy of nRT is clearly stronger than that of surgical therapy alone (p<0.001), surgery combined with chemotherapy (p<0.001), and aRT (p = 0.008) in patients with T4 stage. The survival analysis results were consistent before and after propensity score matching. CONCLUSION In these carefully selected patients, the present study made the following recommendations: nRT can improve the prognosis of patients with T3N0M0/T1-3N+M0 and T4 Siewert type II GEA, and it seems to be a better treatment for T4 patients. Surgery alone seems to be sufficient, and nRT is not conducive to prolonging the survival of Siewert II GEA patients with T1-2N0M0 stage. Of course, further prospective trials are needed to verify this conclusion.

Abstract
Background The controversy regarding optimal clinical T2N0 esophageal cancer treatment ultimately stems from the clinical staging modalities’ inaccuracy. Because most inaccuracies lie in clinical T2 to pathological T1, it is vital to discriminate whether the muscularis propria is invaded. Methods We investigated the association between the primary tumor maximal standard uptake value (SUVmax), and the pathological features and overall survival. We attempted to construct a discriminative model through logistic regression analysis. Results A total of 140 cN0 esophageal squamous cell carcinoma (ESCC) patients were enrolled. Primary tumor SUVmax differed significantly in paired pathological T categories (P<0.05), but not pT2 vs. pT3 (P=0.648). Age (≤65 vs. >65), biopsy differentiation grades (well or moderately vs. poorly vs. unknown), and primary tumor SUVmax (continuous) were independent risk factors for invasion depth. Subsequently, the age categories, the biopsy differentiation grade categories, and the primary tumor SUVmax categories (≤7.4 vs. >7.4) were included in the logistic regression analysis to construct a discriminative model, showing a good performance in discriminating pT2–3 vs. pT1 in terms of accuracy 87.1%, sensitivity 93.6%, specificity 73.9%, and area under the curve (AUC) 0.887 [95% confidence interval (CI): 0.822 to 0.951]. Of these factors, biopsy differentiation grades and primary tumor SUVmax showed significant differences in overall survival (P<0.05), while the age categories did not. Conclusions The novel baseline model comprised of age, biopsy differentiation grades, and primary tumor SUVmax provide much discriminative performance in determining whether the muscularis propria is invaded. Further studies are necessary to validate the findings and guide clinical practice for cT2N0 esophageal cancer.

Abstract
Background Complete tumor removal via esophagectomy or endoscopic excision has been associated with the greatest survival in early-stage esophageal cancer. However, patient health, anatomy, or goals of care may render patients ineligible for excision or resection. In this setting, chemoradiation (CRT) may be considered as a nonsurgical approach, however the outcomes associated with CRT in early-stage esophageal cancer are incompletely understood. Methods The National Cancer Database was queried for treatment-naïve cT1/T2, N0, M0 esophageal cancer patients managed with concurrent multi-agent CRT (≥50 Gy) between 2004 and 2015. Medically inoperable patients were excluded. Kaplan-Meier curves were generated to estimate 5-year overall survival (OS) from diagnosis in both stages. Results Of the 828 patients identified, 279 were cT1 and 549 were cT2. For cases after 2010, cT1 (N=124) was further stratified in cT1a (N=32, 25.8%) and cT1b (N=46, 37.1%). Kaplan-Meier estimates demonstrated a 5-year survival of 21.7% for cT1 and 25.9% for cT2. Sensitivity analyses were performed to mitigate competing survival risk from poor health. Among 589 comorbidity-free patients (i.e., Charlson = score zero), the 5-year survival with CRT was 23.4% for cT1 and 27.8% for cT2. Finally, a subset of patients who refused a recommended surgery were evaluated with 5-year survival cT1 =33.5% and cT2 =33.4%). Conclusions Up to a third of selected patients with early-stage esophageal cancer may be cured after CRT as definitive non-surgical treatment. However, cure rates may be underestimated in this setting, secondary to persistent health-related bias.

Abstract
Background This study investigated the prognostic impact of (neo‐)adjuvant radiation therapies in early stage esophageal cancer. Methods A retrospective analysis using the Surveillance, Epidemiology, and End Results (SEER) database was conducted from 2004 to 2016. Patients with pathologically staged T1‐4N0M0 esophageal cancer were divided into two treatment groups: (i) neoadjuvant radiotherapy followed by surgery; and (ii) upfront esophagectomy followed by adjuvant radiotherapy. Propensity scored match and Cox proportional hazards model were used to identify covariates associated with overall survival and cancer‐specific survival. Results There were 821 patients selected, of whom 588 (71.6%) received neoadjuvant radiotherapy and 233 (28.4%) received adjuvant radiotherapy. For the entire cohort, neoadjuvant radiotherapy was associated with a significantly benefit in five‐year survival outcomes compared with adjuvant radiotherapy (P < 0.01). After matching, the survival outcomes were still better for neoadjuvant radiotherapy than that of adjuvant treatment. Stratifying based on pathologic tumor status, neoadjuvant radiation was associated with improved CSS (five‐year survival 73.7% vs. 42.1%; P = 0.014) for localized (pT3‐4N0) disease. The Cox multivariate regression analysis revealed that the addition of neoadjuvant radiation for pT3‐4N0 diseases with tumor length ≥ 5 cm and squamous cell carcinoma, was a powerful prognostic factor for improved cancer‐specific survival (P < 0.01). Conclusions Compared with adjuvant radiotherapy, the addition of neoadjuvant radiation for pT3‐4N0 diseases has been associated with improved cancer‐specific survival in high‐risk patients. Studies on preoperative neoadjuvant therapies would be plausible in high‐risk esophageal cancer patients.

Abstract
BACKGROUND Induction therapy for patients with cT2N0M0 esophageal cancer is controversial. We performed a retrospective cohort analysis of the National Cancer Database to examine the patterns of use of induction therapy for this population. METHODS The National Cancer Database was queried for patients with cT2N0M0 esophageal cancer who underwent esophagectomy (2004-2015). Patients were stratified by upfront surgery or induction therapy. Overall survival was analyzed and a multivariable logistic regression performed to identify factors associated with receipt of induction therapy. RESULTS Overall 2540 patients met study criteria: 1177 (46%) received upfront esophagectomy and 1363 (53%) received induction therapy. Patients receiving induction therapy were more likely to be younger, male, without comorbidities, privately insured, and treated at a nonacademic center. These patients were also less likely to be treated in highest volume surgery centers. In multivariable regression, factors independently associated with receipt of induction therapy included later year of diagnosis, increasing tumor size, and increasing tumor grade. Factors associated with upfront esophagectomy included advancing age, comorbidities, lack of insurance, geographic location, and highest volume centers. The receipt of induction chemotherapy was not associated with a survival benefit compared with no induction therapy. CONCLUSIONS Several patient-, treatment center-, and tumor-related factors are associated with receipt of induction therapy for cT2N0M0 esophageal cancer, although induction therapy is not associated with a survival benefit. Further inquiry into these differences and the potential benefit or lack thereof of induction therapy should be conducted to provide more equitable and appropriate care for patients with esophageal cancer.

Abstract
BACKGROUND Given the survival advantage of neoadjuvant treatment for locally advanced esophageal cancer, accurate clinical staging is necessary. The aim of this study was to assess the clinical (c) and pathologic (p) staging concordance rates for presumably early stage esophageal adenocarcinoma patients that had upfront esophagectomy (UFE) and evaluate if survival (OS) was negatively affected by inaccurate preoperative staging and subsequent treatment selection. METHODS An NCDB retrospective review of nonmetastatic esophageal adenocarcinoma patients that had UFE. The rates of concordance between c and p staging system and OS were calculated. RESULTS Of 2775 patients, most patients presented with cN0 (82.8%) and cT1 tumors (53.6%). The overall concordance between c and p staging was 78.8% for T-classification (moderate agreement; weighted κ = 0.729; P < .001) and 78.8% for N-classification (weak agreement; weighted κ = 0.448; P < .001). Patients that were upstaged due to a lack of concordance between T-classification had decreased 5- and 10-year OS (30% and 16%, P < .001) and those upstaged due to discordant N-classification had decreased 5- and 10-year OS (28% and 23%, P < .001)." CONCLUSIONS Preoperative staging of esophageal adenocarcinoma has moderate reliability and accuracy for predicting pT and pN classification. Up to 25% of patients have discordant clinical and pathological staging, which impacts OS.

Abstract
BACKGROUND The impact of adjuvant treatment for esophageal carcinoma with tumor-negative lymph nodes after upfront radical esophagectomy is still uncertain. This study investigated the effects of postoperative radiotherapy in pT1-3N0 esophageal carcinoma after radical resection. METHOD We retrospectively identified pT1-3N0M0 esophageal carcinoma patients between 2000 and 2016 from the Surveillance, Epidemiology, and End Results database. Patients with upfront esophagectomy were categorized as having received surgery alone (SA) and surgical resection followed by adjuvant radiotherapy (SA + RT). Propensity score matching, univariate and multivariate analysis were performed to compare overall survival (OS) and cause-specific survival (CSS). RESULTS A total of 2862 patients were identified, of whom 274 received SA + RT and 2588 received SA. The median follow-up was 60.4 months (95%CI, 58.7-62.1 months). The five-year OS and CSS were better for SA group compared with SA + RT group (P < 0.001, respectively). Furthermore, after matching, the OS and CSS were still significantly better for SA patients. For T subgroup analysis, postoperative radiotherapy was an independent prognostic factor only for pT1 patients with worse OS, without survival differences for pT2 and pT3 patients. However, after multivariate cox analysis, postoperative radiotherapy can provide significantly better OS for pT3 patients with tumor length ≥5 cm (P = 0.03; 95%CI, 0.29-0.94). CONCLUSIONS Among pT1-3N0M0 esophageal carcinoma patients, postoperative radiotherapy can provide significantly better OS for pT3 patients with tumor length ≥5 cm. However, there are no survival benefits for pT1-2 patients after SA + RT procedure. This finding may have significant implications on the use of adjuvant radiation in patients with pN0 disease.

Abstract
Background Despite modern imaging modalities, staging of clinically staged T2N0M0 (cT2N0M0) oesophageal cancer is suboptimal, often leading to overtreatment. Endoscopic resection – the first-line therapy for early localised tumours – could be used to improve staging and to attain predictors of nodal upstaging enabling more stage-guided treatment decisions. Objective A systematic literature review and a meta-analysis were conducted to assess the prevalence and the pathological risk factors of lymph node metastases in cT2N0M0 oesophageal cancer. Methods Databases of PUBMED, EMBASE and Cochrane were searched for literature. The primary outcome was lymph node metastases determined after primary surgical resection. Results Nine studies with a total of 1650 cT2N0M0 patients were included. The prevalence of lymph node metastases was 43% (95% confidence interval: 35–50%) with heterogeneity being high across studies (I2 = 0.86, p < 0.001). Factors potentially attainable by endoscopic resection and having a significant association with lymph node metastases were invasion depth, differentiation grade, tumour size, depth of invasion in the muscularis propria and lymphovascular invasion. Conclusions Clinical lymph node staging is inaccurate in almost half of cT2N0M0 oesophageal cancer. Endoscopic resection is a promising diagnostic modality that might even be a valid alternative to surgery in selected patients without high-risk features, but further evidence is warranted.

Abstract
While management of locally advanced esophageal cancer has mostly involved multimodality therapy, management of clinical T2N0 patients has been more controversial, primarily as a result of inaccurate clinical staging with existing modalities. This review article examines current literature on this topic and provides recommendations for management of individual patients.
