Risk factors for recurrence of esophageal squamous cell carcinoma after pathological complete response to neoadjuvant therapy followed by esophagectomy. World J Surg 2024; 48:1700-1709. [PMID: 38757868 DOI: 10.1002/wjs.12212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Accepted: 05/02/2024] [Indexed: 05/18/2024]
Abstract
BACKGROUND Prognosis of patients who achieve pathological complete response (pCR) with neoadjuvant therapy (NAT) is better than that of non-pCR patients. Currently, there is no indication for adjuvant immune checkpoint inhibitor therapy after achieving pCR. However, recurrence risk after pCR is reportedly 10%-20% with a poor prognosis. Therefore, we investigated the preoperative risk factors for recurrence in patients with pCR. METHODS We analyzed 56 patients with esophageal squamous cell carcinoma who underwent esophagectomy after neoadjuvant chemoradiotherapy (NACRT) or neoadjuvant chemotherapy (NAC) and were histologically diagnosed with pCR. Preoperative factors were compared between patients with and without recurrence to identify the risk factors. RESULTS Forty-eight patients who achieved pCR received NACRT and 8 received NAC. Ten patients who experienced recurrence (17.9%) had undergone NACRT. The cN2 lesions were more frequent, and pre-NAT blood hemoglobin (Hb) was lower in the recurrence group. In addition, the pre-NAT cross-sectional area (CSA) product of the major and minor diameters of the primary tumor before NAT was significantly higher in recurrent cases (p = 0.041). Multivariate analysis, including the cTNM stage, pre-NAT Hb, and pre-NAT CSA, identified high pre-NAT CSA as the only risk factor for recurrence (odds ratio 11.6, 95% confidence interval 1.3-104.1, and p = 0.028). Cox regression analysis of recurrence-free and overall survival identified only high pre-NAT CSA as a prognostic factor. CONCLUSIONS The recurrence risk is relatively high even in patients who achieve pCR after NAT. High pre-NAT CSA of the primary tumor is a risk factor for recurrence necessitating close surveillance.

Clin Pract 2024; 14:642-652. [PMID: 38666809 PMCID: PMC11049241 DOI: 10.3390/clinpract14020051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 04/11/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
PURPOSE We conducted a phase II study evaluating chemoradiotherapy in patients with advanced esophageal cancer, using the docetaxel, cisplatin, and 5-fluorouracil (DCF) regimen followed by surgery. The primary purposes of this clinical trial were to assess the efficacy and safety of chemoradiotherapy employing the DCF regimen in the treatment of advanced esophageal cancer. MATERIAL AND METHODS We enrolled a total of 24 newly diagnosed esophageal cancer patients between April 2015 and November 2017 in this prospective study. The radiotherapy regimen consisted of a total dose of 45 Gy in 25 fractions. The chemotherapy protocol included docetaxel 35 mg/m2 for 1 h on day 1 and day 29, cisplatin 35 mg/m2 for 1 h on day 1 and day 29, and 5-FU 400 mg/m2 for 24 h on day 1-4 and day 29-32. The patients who accepted the re-staging exam should undergo surgery in 4-8 weeks after the completion of radiotherapy. The primary endpoints of this study were disease-free survival (DFS), overall survival (OS), and the evaluation of hematologic toxicity. RESULTS The study population had a median age of 55.5 years, ranging from 44 to 66, with over 90% of the patients being male. The 5-year DFS was 37.1%, and the 5-year OS was 48.7%. The pathologic complete response rate was 45.8% (11/24). The most common types of toxicity were leukopenia and thrombocytopenia. No grade 3 or greater hematologic toxicity was reported. CONCLUSIONS The use of the DCF regimen in neoadjuvant chemoradiotherapy followed by surgery demonstrated tolerable toxicity and achieved acceptable DFS and OS outcomes.

Abstract
PURPOSE Various treatments are used for early postoperative recurrence of esophageal cancer, which has a poor prognosis. We evaluated the differences in outcomes and prognoses of each treatment modality between patients with early and late recurrence. METHODS Early and late recurrence were defined as recurrence within and after six postoperative months, respectively. Of the 351 patients with esophageal squamous cell carcinoma who underwent R0 resection esophagectomy, 98 experienced postoperative recurrence (early recurrence, n = 41; late recurrence, n = 57). We evaluated the characteristics of patients with early and late recurrence and compared their treatment responses and prognoses. RESULTS Regarding treatment responses for chemotherapy or immunotherapy, the objective response rate was not significantly different between the early- and late-recurrence groups. For chemoradiotherapy, the objective response rate was significantly lower in the early-recurrence group than in the late-recurrence group. The overall survival was significantly worse in the early-recurrence group than in the late-recurrence group. An analysis by treatment type showed that the early-recurrence group had significantly worse overall survival for chemoradiotherapy, surgery, and radiotherapy than the late-recurrence group. CONCLUSIONS Patients with early recurrence had particularly poor prognoses with worse post recurrence treatment efficacy than those with late recurrence. The differences in the treatment efficacy and prognosis were particularly pronounced for local therapy.

Abstract
PURPOSE This study aimed to determine the pathological complete response (pCR), overall survival (OS), and disease-free survival (DFS) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) using post-neoadjuvant chemoradiotherapy (nCRT) F-18-fluorodeoxyglucose (18FDG). METHODS This is a retrospective study of patients with locally advanced ESCC receiving nCRT and then esophagectomy between January 2011 and December 2018 in the Tri-Service General Hospital, Taipei, Taiwan. A total of 50 patients were enrolled in the study. Survival analysis was performed using the Kaplan-Meier method and Cox proportional hazards model. Univariate and multivariate analysis were used to determine the independent prognostic factors. RESULTS Fifty patients were enrolled in the study, and 18 had pathological complete response. Post-nCRT SUVmax ≥ 3 is a poor prognostic factor associated with overall survival (HR: 3.665, P = 0.013) and disease-free survival (HR: 3.417, P = 0.011). Poor prognosis was found in the non-pCR plus post-nCRT SUVmax ≥ 3 group compared with pCR plus post-nCRT SUVmax < 3 group. CONCLUSIONS SUVmax ≥ 3 is a poor prognostic factor in esophageal squamous cell carcinoma after trimodality treatment, even in patients having pathological complete response.

Abstract
Radiomics transforms the medical images into high-dimensional quantitative features and provides potential information about tumor phenotypes and heterogeneity. We conducted a retrospective analysis to explore and validate radiomics model based on contrast-enhanced computed tomography (CECT) to predict recurrence of locally advanced oesophageal squamous cell cancer (SCC) within 2 years after trimodal therapy. This study collected CECT and clinical data of consecutive 220 patients with pathology-confirmed locally advanced oesophageal SCC (154 in the training cohort and 66 in the validation cohort). Univariate statistical test and the least absolute shrinkage and selection operator method were performed to select the optimal radiomics features. Logistic regression was conducted to build radiomics model, clinical model, and combined model of both the radiomics and clinical features. Predictive performance was judged by the area under receiver operating characteristics curve (AUC), accuracy, and F1-score in the training and validation cohorts. Ten optimal radiomics features and/or 7 clinical features were selected to build radiomics model, clinical model, and the combined model. The integrated model of radiomics and clinical features was superior to radiomics model or clinical model in predicting recurrence of locally advanced oesophageal SCC within 2 years in the training (AUC: 0.879 vs 0.815 or 0.763; accuracy: 0.844 vs 0.773 or 0.740; and F1-score: 0.886 vs 0.839 or 0.815, respectively) and validation (AUC: 0.857 vs 0.720 or 0.750; accuracy: 0.788 vs 0.700 or 0.697; and F1-score: 0.851 vs 0.800 or 0.787, respectively) cohorts. The combined model of radiomics and clinical features shows better performance than the radiomics or clinical model to predict the recurrence of locally advanced oesophageal SCC within 2 years after trimodal therapy.

Good prediction of treatment responses to neoadjuvant chemoradiotherapy for esophageal cancer based on preoperative inflammatory status and tumor glucose metabolism. Sci Rep 2021; 11:11626. [PMID: 34078965 PMCID: PMC8172631 DOI: 10.1038/s41598-021-90753-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 05/17/2021] [Indexed: 01/03/2023] Open
Abstract
To develop a tool for predicting pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (neoCRT) in patients with esophageal cancer by combining inflammatory status and tumor glucose metabolic activity. This study included 127 patients with locally advanced esophageal cancer who had received neoCRT followed by esophagectomy from 2007 to 2016. We collected their neutrophil–lymphocyte ratio (NLR) and standardized uptake value (SUV) obtained from fluorodeoxyglucose positron emission tomography (PET/CT) before and after neoCRT. Univariate and multivariate logistic regression analyses were performed to identify potential predictive factors for pCR. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of predictors were calculated. Between pCR and non-pCR groups, there were no statistically significant differences in patient characteristics, such as sex, age, site, and clinical T/N stage. Multivariate analyses identified four independent predictors for pCR, including pre-OP NLR < 5.4 [OR 11.179; 95% CI 8.385–13.495; p = 0.003], NLR change (ΔNLR) < 3 [OR 4.891; 95% CI 2.274–9.180; p = 0.005], changes in SUV (ΔSUV) > 7.2 [OR 3.033; 95% CI 1.354–6.791; p = 0.007], and SUV changes ratio (ΔSUV ratio) > 58% [OR 3.585; 95% CI 1.576–8.152; p = 0.002]. ΔNLR had the highest accuracy and NPV (84.3% and 90.3%, respectively). Combined factors of ΔNLR < 3 and ΔSUV ratio > 58% had the best PPV for pCR (84.8%). Inflammatory status (ΔNLR) and tumor glucose metabolic activity (ΔSUV ratio), when considered together, constitute a promising low-invasive tool with high efficacy for prediction of treatment response before surgery.

Application of contrast-enhanced CT radiomics in prediction of early recurrence of locally advanced oesophageal squamous cell carcinoma after trimodal therapy. Cancer Imaging 2021; 21:38.

Abstract
Background Early recurrence of oesophageal squamous cell carcinoma (SCC) is defined as recurrence after surgery within 1 year, and appears as local recurrence, distant recurrence, and lymph node positive and disseminated recurrence. Contrast-enhanced computed tomography (CECT) is recommended for diagnosis of primary tumor and initial staging of oesophageal SCC, but it cannot be used to predict early recurrence. It is reported that radiomics can help predict preoperative stages of oesophageal SCC, lymph node metastasis before operation, and 3-year overall survival of oesophageal SCC patients following chemoradiotherapy by extracting high-throughput quantitative features from CT images. This study aimed to develop models based on CT radiomics and clinical features of oesophageal SCC to predict early recurrence of locally advanced cancer. Methods We collected electronic medical records and image data of 197 patients with confirmed locally advanced oesophageal SCC. These patients were randomly allocated to 137 patients in the training cohort and 60 in the test cohort. 352 radiomics features were extracted by delineating region-of-interest (ROI) around the lesion on CECT images and clinical signature was generated by medical records. The radiomics model, clinical model, the combined model of radiomics and clinical features were developed by radiomics features and/or clinical characteristics. Predicting performance of the three models was assessed with area under receiver operating characteristic curve (AUC), accuracy and F-1 score. Results Eleven radiomics features and/or six clinical signatures were selected to build prediction models related to recurrence of locally advanced oesophageal SCC after trimodal therapy. The AUC of integration of radiomics and clinical models was better than that of radiomics or clinical model for the training cohort (0.821 versus 0.754 or 0.679, respectively) and for the validation cohort (0.809 versus 0.646 or 0.658, respectively). Integrated model of radiomics and clinical features showed good performance in predicting early recurrence of locally advanced oesophageal SCC for both the training and validation cohorts (accuracy = 0.730 and 0.733, and F-1score = 0.730 and 0.778, respectively). Conclusions The integrated model of CECT radiomics and clinical features may be a potential imaging biomarker to predict early recurrence of locally advanced oesophageal SCC after trimodal therapy.

Abstract
PURPOSE Predicting the response to neoadjuvant chemoradiotherapy (NCRT) and the prognosis of esophageal squamous cell carcinoma (ESCC) is challenging. This study evaluated the potential of a preoperative computed tomography (CT) analysis for predicting the pathological response and survival of patients with ESCC who received trimodality therapy. METHODS A total of 119 patients with cT3 or T4 ESCC who underwent surgery following NCRT between 2007 and 2019 were assessed. The CT-based parameters were measured with enhanced CT preoperatively, prior to and during treatment. Associations between these parameters and the pathologic response, as well as the prognosis, were examined. RESULTS Pretreatment maximum CT value (p = 0.009), pretreatment mean CT value (p = 0.022), preoperative whole tumor volume (WTV, p = 0.003), preoperative largest cross section (LCS, p = 0.002), ΔLCS (pretreatment to preoperative, p = 0.004), ΔWTV (pretreatment to preoperative, p = 0.012), and Δmean CT value (pretreatment to preoperative, p = 0.012) of the primary lesion were significantly associated with a good pathological response. A Cox-regression analysis of recurrence-free survival (RFS) and overall survival (OS) showed that preoperative LCS was an independent CT-based predictor. RFS and OS were significantly higher at the optimal cut-off value of the preoperative LCS (p = 0.036 and p = 0.016, respectively). CONCLUSIONS CT-based parameters are thus considered to be valuable predictors of the tumor response and survival after trimodality therapy for ESCC.

Abstract
MicroRNAs (miRNAs) in tumor and tumor-adjacent tissues can be effective diagnostic and prognostic markers to monitor tumor occurrence and progression. Despite improvements in the diagnosis and treatment of esophageal cancer (EC), the survival rate is <25%; consequently, more effective EC-specific prognostic biomarkers are urgently needed to design effective treatment regimens. In this study, we focused on identifying independent prognostic miRNA signatures in tumor and tumor-adjacent tissues in EC.We screened candidate miRNAs using a genome-wide miRNA transcriptome dataset from The Cancer Genome Atlas (TCGA) database that included 82 patients with esophageal adenocarcinoma (EADC) and 83 patients with esophageal squamous cell carcinoma (ESCC). We validated potential prognostic miRNA markers using a microarray profiling dataset that included information of 32 patients with EADC and 44 patients with ESCC from the Gene Expression Omnibus database. TCGA dataset was additionally used to identify differentially expressed mRNAs (DEMs) between the tumor and tumor-adjacent tissues. Univariate and multivariate Cox analyses were performed to detect the relationship between miRNAs and the overall survival of patients with EC. Kaplan-Meier method was applied to assess the survival differences between groups with differential miRNA expression. Lastly, functional enrichment analysis was conducted using miRWalk 2.0 online database for annotation.Although there was a considerable difference between the DEMs of EADC and ESCC, 73 DEMs were differentially expressed in both EADC and ESCC samples in TCGA dataset. Cox regression and Kaplan-Meier survival analyses showed that a higher expression of hsa-miR-186-5p and hsa-let-7d-5p was independently associated with a poor prognosis of EADC and ESCC, respectively. Furthermore, gene functional enrichment analysis revealed that the target genes of hsa-miR-186-5p and hsa-let-7d-5p participated in various cancer-related pathways, including the MAPK signaling pathway, proteoglycans in cancer, and AGE-RAGE signaling pathway.Our results revealed that hsa-miR-186-5p and hsa-let-7d-5p could be used as independent prognostic biomarkers for EADC and ESCC, respectively.

Abstract
BACKGROUND Although metastatic tumors in lymph nodes (LN) are potentially affected by neoadjuvant chemoradiotherapy (NCRT), the distribution of LN metastases of esophageal squamous cell carcinoma (ESCC) after trimodal therapy has never been sufficiently estimated. PATIENTS AND METHODS We evaluated the distribution of LN metastases, relationships between LN metastases and radiation fields, risk factors for LN metastasis, and the influence of LN metastasis on the survival of 184 patients with ESCC who underwent NCRT followed by esophagectomy. RESULTS Neoadjuvant chemoradiotherapy resulted in down-staged LN status in 74 (49.3%) patients. Pathological LN metastases were extensive in 177 LN stations in the cervical, mediastinal, and abdominal fields, and 162 (91.5%) metastases were located inside the radiation fields. Multivariate analysis showed that clinical N stage [N0 vs. 1/2/3: hazard ratio (HR), 2.69; 95% confidence interval (CI), 1.22-5.92; p = 0.01] and clinical response of primary tumor (complete vs. noncomplete: HR, 2.93; 95% CI, 1.50-5.69; p = 0.002) were statistically significant for pathological LN metastasis. Recurrence-free and overall survivals were significantly stratified according to the number of pathological LN metastases, associations between clinical and pathological LN metastases, and presence or absence of pathological LN metastases outside radiation field. CONCLUSIONS About 50% of patients who were clinically diagnosed with LN metastasis before treatment were downstaged by NCRT, and their prognoses were relatively good. However, LN metastases were extensive at the cervical, mediastinal, and abdominal areas, even within the radiation field. Thus, systematic and adequate lymphadenectomy is required for ESCC treated by NCRT.

Abstract
BACKGROUND The degree of metabolic activity in tumor cells can be determined by 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET). Associations between FDG uptake by primary tumors of locally advanced esophageal squamous cell carcinoma (ESCC) under trimodal therapy and the pathological features of such tumors have not been fully investigated. PATIENTS AND METHODS We evaluated relationships between the maximal standardized uptake (SUVmax) in primary tumors on preoperative PET images and pathological features as well as cancer recurrence in 143 patients with ESCC who underwent neoadjuvant chemoradiotherapy (NCRT) followed by surgery. RESULTS The post-SUVmax significantly differed after NCRT for ypT and ypN status, lymphatic invasion (LI), venous invasion (VI), and recurrence. Furthermore, the %ΔSUVmax (rate of decrease between before and after NCRT) for LI, VI, and recurrence significantly differed. Univariate and multivariate analyses selected post-SUVmax and %ΔSUVmax as independent preoperative predictors of recurrence-free survival [hazard ratio (HR) 1.46; 95% confidence interval (CI) 1.24-1.72 and HR 0.97; 95% CI 0.96-0.99, respectively; p < 0.001 for both]. Recurrence-free and overall survival were significantly stratified according to optimal SUVmax cutoffs for predicting recurrence (post- and %ΔSUVmax: 2.8 and 70, respectively). CONCLUSIONS The post- and %ΔSUVmax of primary tumors were significantly associated with the pathological features and recurrence of ESCC under trimodal therapy. Therefore, FDG-PET can preoperatively predict the degree of aggressive tumor behavior in ESCC under trimodal therapy.

Abstract
BACKGROUND Preoperative chemoradiotherapy (CRT) is one standard option for localized esophageal or gastroesophageal junction (GEJ) cancer patients but an optimal concurrent chemotherapy combination is not established. METHODS 412 patients with resectable (cT1N1M0 or cT2-4N0-3M0) esophageal or GEJ cancer treated at the MDACC between October 2002 and June 2016 were analyzed. Exposures: CRT with DF or FOX followed by surgery (trimodality; TMT). Main outcomes and measures: Primary endpoints were overall survival (OS) and disease-free survival (DFS). Univariate and multivariate Cox analyses were performed. RESULTS Of the 412 patients analyzed, 264 (64%) received DF and 148 (36%) FOX. The median age was 60 years, and 95% had adenocarcinoma. The clinical complete response, positron-emission tomography response, and pathologic complete response rates were 73%, 73%, and 30%, respectively. Median follow-up was 60.4 months. Median OS for the entire cohort was 81.6 months (95% confidence interval [CI], 56.3-122.0); 81.6 months (95% CI, 55.9-not estimable) for the DF group and 67.7 months (95% CI, 41.6-not estimable) for the FOX group (P = .24). The median DFS was 45.6 months (95% CI, 33.1-61.7) for the entire cohort; 49.5 months (95% CI, 38.6-70.3) for DF and 33.0 months (95% CI, 18.1-70.4; P = .38) for FOX. Higher tumor location (unfavorable) and clinical complete response (favorable) were prognostic for both OS and DFS in the multivariate analysis. CONCLUSION At our high-volume center, the outcome of 412 TMT esophageal cancer patients was excellent. Taxane-based chemotherapy produces nonsignificant favorable trend.

Abstract
Neoadjuvant chemotherapy (NAC) significantly extends survival in advanced esophageal squamous cell carcinoma (ESCC), but the short-term outcomes for cT4 ESCC remain controversial. Many NAC regimens have been previously reported, although no study has reported a regimen of irinotecan and nedaplatin for cT4 potential resectable ESCC. We evaluated the short-term outcomes of NAC with irinotecan and nedaplatin in a single cycle followed by esophagectomy on cT4 resectable ESCC. A total of 51 patients with cT4 potentially resectable ESCC were eligible for this study. Twenty of these patients underwent NAC, and the other 31 patients underwent surgery alone. The toxicities and response of NAC were evaluated. The clinicopathologic characteristics, responses, toxicities, surgical outcomes, postoperative complications, and survival time between the two groups were analyzed. No significant differences were found in clinicopathologic characteristics between the groups (P > 0.05). The response rate of NAC was 75% (15/20). The differences in the long-axis diameter of the tumor and cT stage between pre- and post-NAC were significant (P < 0.05). Twenty-four toxic events occurred in 11 patients of the NAC group, and 20/24 of these were mild. The R0 resection rates in the NAC group and the surgery alone group were 85% and 64.5%, with no statistically significant difference (P > 0.05). Differences in the pathological T stage and pathological tumor-node-metastasis (TNM) stage were significant (P < 0.05). The overall survival (OS) time and mortality in the NAC group versus the surgery alone group were 31.57 ± 3.06 months versus 15.24 ± 1.46 months and 25% versus 61.3%, respectively. The differences in OS and mortality were significant (P < 0.05). The NAC group and R0 resection were significant and independent predictors of positive prognosis. NAC with irinotecan and nedaplatin in a single cycle followed by esophagectomy on cT4 resectable ESCC as a new NAC is safe and effective.

Abstract
BACKGROUND The clinical significance of lymph node (LN) status determined by preoperative 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) has not been investigated in patients with locally advanced esophageal squamous cell carcinoma (ESCC) treated with neoadjuvant chemoradiotherapy (NCRT) followed by surgery (trimodal therapy). METHODS This study reviewed 132 consecutive patients with ESCC who had been preoperatively evaluated using FDG-PET before and after NCRT to analyze associations among LN status according to PET findings, pathologic LN metastasis, and prognosis of ESCC after trimodal therapy. RESULTS Lymph nodes that were PET-positive both before and after NCRT comprised significant predictive markers of pathologic LN metastasis in station-by-station analyses (sensitivity, specificity, and accuracy respectively 41.7%, 95.0%, and 92.7% before, and 12.0%, 99.4%, and 95.6% after NCRT; both p < 0.0001). The numbers of LNs evaluated using PET before and after NCRT were significantly associated with those of pathologic metastatic LNs. Uni- and multivariable analyses selected LN status determined by PET before NCRT as a significant independent predictor of both recurrence-free [LN-negative vs LN-positive: hazard ratio (HR) 1.90; 95% confidence interval (CI) 1.02-3.23; p = 0.045] and overall survival (HR 2.62; 95% CI 1.29-5.30; p = 0.01). CONCLUSIONS The status of LN determined by preoperative FDG-PET is significantly associated with pathologic LN status and the prognosis of ESCC with trimodal therapy. Thus, FDG-PET is a useful diagnostic tool for preoperative prediction of pathologic LN metastasis and survival among patients with ESCC.

Abstract
The survival advantage of radiotherapy (RT) for patients with metastatic esophagus cancer has not been adequately evaluated. This study aims to find out the role of RT for metastatic esophagus cancer and to find the different effect for RT to esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC). This study included 5,970 metastatic esophagus cancer patients from the Surveillance, Epidemiology, and End Results (SEER) database, registered from January 2004 to December 2013. Propensity score (PS) analysis with 1:1 nearest neighbor matching method was used to ensure well-balanced characteristics of all comparison groups by histological types. The Kaplan-Meier and Cox proportional hazardous models were used to evaluate the overall survival (OS), cancer-specific survival (CSS), and corresponding 95% confidence interval (CI). Generally speaking, EAC did not get survival benefit from RT (median OS for RT group vs. no-RT group-8.0, 7.6-8.4 vs. 9.0, 8.5-9.5, P = 0.073), whereas RT for metastatic ESCC did significantly improve OS (median OS for RT group vs. no-RT group-8.0, 7.4-8.6 vs. 7.0, 6.4-7.6, P = 0.044). Therefore, compared with adenocarcinoma, ESCC could get more survival benefit from RT.

Abstract
BACKGROUND Intensive trimodality therapy is needed for locally advanced esophageal squamous cell carcinoma (ESCC). However, some patients develop recurrence and die of cancer even after trimodality therapy. METHODS We evaluated prognostic factors based on data from 125 patients with ESCC who underwent neoadjuvant chemoradiotherapy (NCRT) comprising concurrent chemotherapy and 40 Gy of radiation, followed by curative-intent esophagectomy. RESULTS Thirty-four (27.2%) patients achieved a pathological complete response (pCR) after NCRT. The 5-year recurrence-free (RFS) and overall survival (OS) rates of all patients were 49.2 and 52.9%, respectively, and were significantly better for patients with pCR than without pCR (p = 0.01 and 0.02, respectively). Univariate and multivariate analyses selected performance status [PS 0 vs. 1: hazard ratio (HR) 2.05; 95% confidence interval (CI) 1.30-4.84; p = 0.01] and ypN (0 vs. 1: HR 2.33; 95% CI 1.12-4.84; p = 0.02; 0 vs. 2/3: HR 3.73; 95% CI 1.68-8.28; p = 0.001) as independent covariates for RFS. Furthermore, PS (0 vs. 1; HR 2.94; 95% CI 1.51-5.72; p = 0.002) and ypN (0 vs. 1; HR 2.26; 95% CI 1.09-4.69; p = 0.03; 0 vs. 2/3: HR 3.90; 95% CI 1.79-8.48; p = 0.001) were also independent covariates for OS. CONCLUSIONS Performance status 1 and ypN+ were significantly associated with a poor prognosis after trimodality therapy for ESCC.

Abstract
BACKGROUND The accurate prediction of a pathologic complete response (ypT0N0M [LYM] 0 ypStage 0) before operation is essential for selecting appropriate strategies for treating esophageal cancer after neoadjuvant chemoradiotherapy. METHODS We reviewed 130 consecutive patients with esophageal squamous cell carcinoma who were evaluated preoperatively using upper gastrointestinal endoscopy, computed tomography, and 18F-fluorodeoxyglucose-positron emission tomography after neoadjuvant chemoradiotherapy and subsequently underwent esophagectomy. Our aim was to determine the diagnostic abilities of computed tomography, 18F-fluorodeoxyglucose-positron emission tomography, and endoscopy to predict preoperatively a pathologic complete response of the primary site of the locally advanced esophageal squamous cell carcinoma and associated lymph nodes to trimodal neoadjuvant chemoradiotherapy. Associations between clinical complete response (ycT0N0M [LYM] 0 ycStage 0) and pathologic complete response were investigated preoperatively. RESULTS Twenty-nine (22.3%) and 43 (33.1%) patients, respectively, achieved clinical complete response and pathologic complete response, which were associated (P=.001). The sensitivity and specificity, as well as the positive and negative predictive values of clinical complete response to define pathologic complete response were 39.5%, 86.2%, 58.6%, and 74.3%, respectively. Univariate and multivariate analyses selected clinical complete response as the sole independent preoperative predictor of pathologic complete response (clinical complete responses versus non-clinical complete responses: odds ratio: 0.26, 95% confidence interval, 0.10-0.65, P=.004). Recurrence-free and overall survival (OS) rates were better in patients with than in those without clinical complete response (5-year recurrence-free and overall survival: 69.0% vs 41.4% and 75.9% vs 45.0%, respectively, both P=.02). Furthermore, clinical complete response was an independent preoperative predictor of recurrence-free survival (clinical complete response versus nonclinical complete response: hazard ratio: 2.20, 95% confidence interval, 1.08-4.45, P=.03). CONCLUSION Although pathologic complete response was predictable preoperatively to some extent, the accuracy was somewhat low. Considerable caution should be exercised when selecting the watch-and-wait approach with operation as needed and omitting planned operative intervention even for patients who achieve clinical complete response after neoadjuvant chemoradiotherapy.

Abstract
The incidence and mortality trends of oesophageal cancer are changing significantly across the world with considerable heterogeneity between sex, histological types, ethnic patterns and geographical distribution. Recent oesophageal cancer incidence and mortality trends have been analysed using data available from the WHO mortality database, the GLOBOCAN 2012 database and the Cancer Incidence in Five Continents database managed by the International Agency for Research on Cancer. Huge geographical variation is an epidemiological characteristic of oesophageal cancer, with the highest incidence rates observed in Eastern Asia and in Eastern and Southern Africa and the lowest rates observed in Western Africa. The variation is to the order of more than 21 times between the lowest-incidence and the highest-incidence countries. Although the incidence of squamous cell carcinoma is increasing globally, its incidence rates are decreasing in the USA and a few European countries. However, the decrease in the incidence of squamous cell carcinomas in these countries has been accompanied by a marked increase in adenocarcinoma incidence rates. There is a significant sex variation as well, with men being affected three to four times more commonly than women worldwide. The observed trends reflect significant global variations in the incidence and mortality of oesophageal cancers on the basis of sex, geographical distribution, ethnicity and histology. These epidemiological factors related to oesophageal cancers point out a possibly significant role of molecular epidemiological factors (genetic susceptibility and response to treatment) with major differences likely between the characteristics of Asian and Western populations.

Comparison of short-term outcomes between 2- and 3-field lymph node dissection for esophageal cancer. Dis Esophagus 2017; 30:1-8. [PMID: 28881906 DOI: 10.1093/dote/dox096] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2017] [Indexed: 12/11/2022]
Abstract
Although 3-field lymph node dissection (3-FLD) is often performed for thoracic esophageal squamous cell carcinoma (ESCC), the clinical effects of cervical lymph node dissection in addition to mediastinal and abdominal dissections on postoperative complications remain unclear. A total of 367 ESCC patients who underwent curative esophagectomy for thoracic esophageal cancer in our hospital from 2010 to 2015 were included in the study: 157 patients who underwent 2-field lymph node dissection (2-FLD) and 210 patients who underwent 3-FLD. Clinicopathological parameters and postoperative complications based on the Clavien-Dindo classification were compared between the two groups. We performed propensity score matching (PSM) analyses to compare the groups with well-balanced backgrounds. In terms of patient background, clinical T (p < 0.001), N (p < 0.001), and M (p = 0.002) stage of tumor was significantly more advanced; therefore, preoperative treatment was more frequently performed in the 3-FLD group than in the 2-FLD group (91.0% vs. 79.0%, P< 0.001). However, perioperative parameters including operation time, blood loss, and the number of dissected mediastinal and abdominal lymph nodes did not differ between the groups. In terms of postoperative complications, the occurrence rate of pneumonia increased significantly in patients with 3-FLD compared to 2-FLD (grade III or higher: 10.5% vs. 3.2%, P= 0.025). Although the duration of systemic inflammatory response syndrome (SIRS) was longer in the 3-FLD group than in the 2-FLD group (median 3 days vs. 2 days, P= 0.025), other postoperative parameters (including the highest level of postoperative serum C-reactive protein, intensive care unit stay, re-operation rate, and postoperative hospital stay) were similar between the groups. After PSM, the differences in the background between the groups disappeared. PSM analysis showed that there was no significant difference in each complication between the groups. The duration of SIRS tended to be longer in the 3-FLD group than in the 2-FLD group, but the difference was not significant. The field of lymphadenectomy negatively impacted the short-term outcome in ESCC patients in terms of pneumonia and inflammatory response. However, because the results of the PSM analyses indicate that the short-term outcome was similar between the two groups, 3-FLD could be as feasible as 2-FLD in ESCC patients.

Abstract
BACKGROUND For patients diagnosed with locally advanced esophageal cancer, neoadjuvant therapy followed by surgery is the most common approach. However, randomized trials resulted in inconsistent conclusions. We conducted this retrospective study to evaluate the influence of neoadjuvant therapy on postoperative events and the influence on disease-free survival (DFS) and overall survival (OS). METHODS We retrospectively reviewed all of the patients underwent surgery following neoadjuvant therapy for locally advanced esophageal squamous cell carcinoma (ESCC) during January 1st, 2013 and December 31st, 2015 in Fudan University Shanghai Cancer Center (FUSCC). Prognostic factors for DFS and OS were identified by univariate and multivariate analyses. RESULTS A total of fifty patients were included. Regarding postoperative morbidities, pneumonia and leakage occurred in 9 (18.0%) and 6 (12.0%) patients, respectively. For the whole patients, the 1-, 2-, 3-year DFS and OS rates were 57.0%, 48.0%, 42.0% and 86.0%, 73.0%, 62.0%, respectively. Lung metastasis and mediastinal node involvement were the most common relapse patterns. Univariate and multivariate analyses confirmed ypTNM stage as an independent prognostic factor for both DFS and OS; while leakage was an independent prognostic factor for DFS. CONCLUSIONS Neoadjuvant therapy did not increase postoperative morbidities but did achieve favorable survival. The ypTNM stage was an independent prognostic factor for both DFS and OS. Long-term survival needs further investigation.

Ann Thorac Surg 2016; 102:1132-9.

Abstract
BACKGROUND Responses of esophageal cancer to neoadjuvant therapy and patient prognosis are difficult to predict preoperatively. This study aimed to determine the ability of fluorine-18 fluorodeoxyglucose ((18)FDG) positron emission tomography (FDG-PET) to predict outcomes of trimodal therapy on esophageal squamous cell carcinoma (ESCC). METHODS The responses of 111 patients with ESCC were monitored using FDG-PET before and after neoadjuvant chemoradiotherapy (nCRT) followed by surgical treatment. Associations between the maximum standardized uptake value (SUVmax) and pathologic responses (PRs) and prognosis were analyzed. RESULTS Responses were significantly associated with SUVmax after nCRT (post-SUVmax) and with the rate of decreases in the SUVmax (%ΔSUVmax) of the primary tumor. The optimal cutoffs for post-SUVmax and %ΔSUVmax determined from receiver operating characteristic (ROC) curves were 2.7 (area under the curve [AUC], 0.68; 95% confidence interval [CI], 0.58-0.78; p = 0.001) and 75 (AUC, 0.64; 95% CI, 0.54-0.75; p = 0.01) for predicting a pathologic complete response (pCR) and 3.7 (AUC, 0.76; 95% CI, 0.63-0.89; p < 0.001) and 70 (AUC, 0.65; 95% CI, 0.52-0.78; p = 0.02) for predicting a good response according to Japan Esophageal Society response criteria. These values reliably separated patients into groups with and without pCR and with and without a good response. Multivariate analysis showed that %ΔSUVmax (≤70 and >70) was an independent prognostic factor for disease-specific survival (hazard ratio [HR], 0.45; 95% CI, 0.21-0.98; p = 0.04). CONCLUSIONS SUVmax is a valuable preoperative predictor of tumor response and survival among patients who undergo trimodal therapy for ESCC.

Intensity modulated radiation therapy with simultaneous integrated boost based dose escalation on neoadjuvant chemoradiation therapy for locally advanced distal esophageal adenocarcinoma. World J Gastrointest Oncol 2016; 8:474-480.

Abstract
AIM: To evaluate impact of radiation therapy dose escalation through intensity modulated radiation therapy with simultaneous integrated boost (IMRT-SIB).
METHODS: We retrospectively reviewed the patients who underwent four-dimensional-based IMRT-SIB-based neoadjuvant chemoradiation protocol. During the concurrent chemoradiation therapy, radiation therapy was through IMRT-SIB delivered in 28 consecutive daily fractions with total radiation doses of 56 Gy to tumor and 5040 Gy dose-painted to clinical tumor volume, with a regimen at the discretion of the treating medical oncologist. This was followed by surgical tumor resection. We analyzed pathological completion response (pCR) rates its relationship with overall survival and event-free survival.
RESULTS: Seventeen patients underwent dose escalation with the IMRT-SIB protocol between 2007 and 2014 and their records were available for analysis. Among the IMRT-SIB-treated patients, the toxicity appeared mild, the most common side effects were grade 1-3 esophagitis (46%) and pneumonitis (11.7%). There were no cardiac events. The Ro resection rate was 94% (n = 16), the pCR rate was 47% (n = 8), and the postoperative morbidity was zero. There was one mediastinal failure found, one patient had local failure at the anastomosis site, and the majority of failures were distant in the lung or bone. The 3-year disease-free survival and overall survival rates were 41% (n = 7) and 53% (n = 9), respectively.
CONCLUSION: The dose escalation through IMRT-SIB in the chemoradiation regimen seems responsible for down-staging the distal esophageal with well-tolerated complications.

Abstract
BACKGROUND For some types of cancer, postoperative complications can negatively influence survival, but the association between these complications and oncological outcomes is unclear for patients with esophageal cancer who receive preoperative treatments. METHODS Data were retrospectively analyzed for patients who underwent curative resection following preoperative chemotherapy for esophageal squamous cell carcinoma from 2001 to 2011. Clinicopathological parameters and cancer-specific survival (CSS) were compared between patients with and without severe postoperative complications, grade III or higher, using the Clavien-Dindo classification. RESULTS Of 255 patients identified, 104 (40.8 %) postoperatively developed severe complications. The most common complication was atelectasis in 61 (23.9 %), followed by pulmonary infection in 22 (8.6 %). Three-field lymphadenectomy, longer operation time, and more blood loss were significantly associated with a higher incidence of severe complications. Multivariate analysis of CSS revealed severe complications [hazard ratio (HR) = 1.642, 95 % confidence interval (95 % CI) 1.095-2.460, p = 0.016] as a significant prognostic factor along with pT stage [HR = 2.081, 95 % CI 1.351-3.266, p < 0.001] and pN stage [HR = 3.724, 95 % CI 2.111-7.126, p < 0.001], whereas postoperative serum C-reactive protein value was not statistically significant. Among all complications, severe pulmonary infection was the only independent prognostic factor [HR = 2.504, 95 % CI 1.308-4.427, p = 0.007]. CONCLUSIONS The incidence of postoperative infectious complications, in particular pulmonary infection, is associated with unfavorable prognosis in patients with esophageal cancer undergoing preoperative chemotherapy.
