Abstract
BACKGROUND Neoadjuvant chemotherapy followed by esophagectomy is the standard treatment for resectable advanced esophageal squamous cell carcinoma (ESCC) in Japan. Triplet chemotherapy is the standard neoadjuvant regimen. Inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) are well-known prognostic factors for esophageal cancer. However, their usefulness in patients with resectable advanced disease undergoing esophagectomy after neoadjuvant triplet chemotherapy is unknown. METHOD We examined 144 ESCC patients who underwent neoadjuvant triplet chemotherapy followed by esophagectomy between January 2015 and December 2020 to investigate the relationship between inflammatory markers and recurrence-free survival (RFS). Optimal marker cutoff values for RFS were determined using receiver operating characteristic curve analysis. Patients were divided into high and low NLR groups (NLR cutoff, 3.0). RESULTS NLR was high in 61 patients and low in 83. Univariate analyses demonstrated that low NLR was significantly associated with worse RFS (p = 0.049). Multivariate analyses demonstrated that high NLR was an independent predictor of RFS (odds ratio, 1.911; 95% confidence interval, 1.098-3.327; p = 0.022). RFS significantly differed between the low and high NLR groups. RFS did not significantly differ between the patients when stratified according to the other inflammatory markers. CONCLUSION Preoperative NLR is an easily obtained and useful predictor of RFS in patients with resectable advanced ESCC treated with neoadjuvant triplet chemotherapy followed by esophagectomy.

PLoS One 2024; 19:e0300173. [PMID: 38547184 PMCID: PMC10977715 DOI: 10.1371/journal.pone.0300173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 02/22/2024] [Indexed: 04/02/2024] Open
Abstract
Large primary tumor volume has been identified as a poor prognostic factor of esophageal squamous cell carcinoma (ESCC) treated with definitive concurrent chemoradiotherapy (CCRT). However, when neoadjuvant CCRT and surgery are adopted, the prognostic impact of primary tumor and lymph node (LN) volume on clinical outcomes in ESCC remains to be elucidated. This study included 107 patients who received neoadjuvant CCRT and surgery for ESCC. The volume of the primary tumor and LN was measured using radiotherapy planning computed tomography scans, and was correlated with overall survival (OS), disease-free survival (DFS), and cancer failure pattern. The median OS was 24.2 months (IQR, 11.1-93.9) after a median follow-up of 18.4 months (IQR, 8.1-40.7). The patients with a baseline LN volume > 7.7 ml had a significantly worse median OS compared to those with smaller LN volume (18.8 vs. 46.9 months, p = 0.049), as did those with tumor regression grade (TRG) 3-5 after CCRT (13.9 vs. 86.7 months, p < 0.001). However, there was no association between OS and esophageal tumor volume (p = 0.363). Multivariate analysis indicated that large LN volume (HR 1.753, 95% CI 1.015-3.029, p = 0.044) and high TRG (HR 3.276, 95% CI 1.556-6.898, p = 0.002) were negative prognostic factors for OS. Furthermore, large LN volume was linked to increased locoregional failure (p = 0.033) and decreased DFS (p = 0.041). In conclusion, this study demonstrated that large LN volume is correlated with poor OS, DFS, and locoregional control in ESCC treated with neoadjuvant CCRT and esophagectomy.

A novel tumor staging system incorporating cN status for stratifying early stage esophageal squamous cell carcinoma patients after trimodal therapy. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:107264. [PMID: 37977046 DOI: 10.1016/j.ejso.2023.107264] [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: 09/19/2023] [Revised: 10/23/2023] [Accepted: 11/08/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUNDS The aim of this study is to investigate the prognostic value of cN status for early stage esophageal squamous cell carcinoma (ESCC) patients after neoadjuvant chemoradiotherapy (nCRT) and construct a new staging model for individual survival prediction. METHODS Patients with ESCC who underwent nCRT and esophagectomy were included in this study. Both the Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC) were meticulously ascertained to assess the cogency of each oncological staging system. A discernible abatement in the values of AIC and BIC signifies a model endowed with enhanced predictive prowess and exemplary veracity. RESULTS A new staging model was established based on ypTNM stage and cN status by precisely stratifying ypI ESCC patients. The novel ypTNM-cN staging demonstrated superior overall survival trend alignment over the AJCC 8th ypTNM staging, with a notably lower AIC of 3143.014 versus 3149.950. This superiority was supported by a BIC of 3146.605 against 3153.541. In the context of disease-free survival outcomes, the emergent ypTNM-cN staging, with an AIC value registering at 3196.057 and a BIC value at 3199.648, distinctively eclipsed the AJCC 8th ypTNM staging, which documented values of 3203.853 and 3207.444, respectively. CONCLUSION We constructed a new staging system based on ypTNM stage and cN status to precisely stratify the patients with ypI stage. Our new ypTNM-cN staging system provides new insights for classifying stage ypI ESCC and shows reliable classification efficacy for all ESCC patients after nCRT and surgery.

Abstract
BACKGROUND Neoadjuvant chemotherapy followed by surgery is Japan's most effective treatment modality for advanced thoracic esophageal squamous cell carcinoma. However, the prognosis is not as expected. This study aimed to examine prognostic factors in patients with pathologically ineffective neoadjuvant chemotherapy followed by surgery for esophageal squamous cell carcinoma. METHODS We retrospectively analyzed patients who underwent neoadjuvant chemotherapy followed by curative esophagectomy for esophageal squamous cell carcinoma between December 2008 and July 2021. The patients were divided into the neoadjuvant chemotherapy effective group and the neoadjuvant chemotherapy ineffective group according to the pathological diagnosis. Clinicopathological data, prognosis, and recurrence were analyzed. RESULTS A total of 143 patients (121 males, 22 females; median age, 67 years) were included in this study. Of these, 34 patients were classified into the effective group and the remaining 109 patients were assigned to the ineffective group. The ineffective group had significantly worse overall survival and recurrence-free survival than the effective group (p = 0.0192 and p = 0.0070, respectively). In the ineffective group, multivariate analysis demonstrated that microscopic venous invasion was an independent prognostic factor for overall survival (hazard ratio 2.44; 95% confidence interval 1.13-5.30) and recurrence-free survival (hazard ratio 2.43; 95% confidence interval 1.24-4.73). CONCLUSIONS Microscopic venous invasion was associated with poor survival and cancer recurrence in the neoadjuvant chemotherapy ineffective group of patients who underwent esophagectomy for esophageal squamous cell carcinoma.

Abstract
PURPOSE Accurate prediction of prognosis and pathological response to neoadjuvant chemotherapy (NAC) is crucial for optimizing treatment strategies for patients with locally advanced esophageal cancer (LA-EC). This study aimed to investigate the use of radiomics for pretreatment CT in predicting the pathological response of patients with LA-EC to NAC. METHODS Overall, 144 patients (145 lesions) with LA-EC who underwent pretreatment contrast-enhanced CT and then received NAC followed by surgery with pathological tumor regression grade (TRG) analysis were enrolled. The obtained dataset was randomly divided into training and validation cohorts using fivefold cross-validation. CT-based radiomic features were extracted followed by the feature selection process using the variance threshold, SelectKBest, and least absolute shrinkage and selection operator methods. The radiomic model was constructed using six machine learning classifiers, and predictive performance was evaluated using ROC curve analysis in the training and validation cohorts. RESULTS All patients were divided into responders (n = 40, 28%) and non-responders (n = 104, 72%) based on the TRG results and a statistically significant split by overall survival analysis (0.899 [0.754-0.961] vs. 0.630 [0.510-0.729], respectively). There were no significant differences between responders and non-responders in terms of age, sex, tumor size, tumor location, or histopathology. The mean AUC of fivefold in the validation cohort was 0.720 (confidence interval [CI]: 0.594-0.982), and the best AUC of the radiomic model using logistic regression to predict the non-responders was 0.815 (CI: 0.626-1.000, sensitivity 0.620, specificity 0.860). CONCLUSION A radiomic model derived from contrast-enhanced CT may help stratify chemotherapy effect prediction and improve clinical decision-making.

Abstract
BACKGROUND Neoadjuvant docetaxel plus cisplatin and 5-FU (NAC-DCF) and adjuvant nivolumab monotherapy are the standard care for locally advanced resectable esophageal squamous cell carcinoma (ESCC). However, no effective biomarkers have been found in perioperative setting. We investigated how programmed death-ligand 1 (PD-L1) changes before and after NAC-DCF and how it relates to the therapeutic effect of NAC-DCF in resectable ESCC. METHODS PD-L1 expression in paired diagnostic biopsy and surgically resected tissues from ESCC patients who underwent surgical resection after receiving two or three NAC-DCF cycles was evaluated. PD-L1 positivity was defined as a combined positive score (CPS) of 10% ≤ . Gene expression analysis was conducted using samples before NAC-DCF. RESULTS Sixty-six paired samples from 33 patients were included in PD-L1 expression analysis, and 33 Pre-NAC samples acquired by diagnostic biopsy were included in gene expression analysis. Pretreatment, 3 (9%), 13 (39%), and 17 (52%) patients harbored tumors with CPS ranges of < 1%, 1%-10%, and 10% ≤ , respectively. After NAC-DCF, 5 (15%), 15 (45%), and 13 (39%) tumors presented CPS ranges of < 1%, 1%-10%, and 10% ≤ , respectively. The concordance rate between Pre-and Post-NAC-DCF samples was 45%. Patients with PD-L1-negative tumors both before and after NAC-DCF (n = 9) had shorter survival and different gene expression profile characterized by upregulation in WNT signaling or neutrophils. CONCLUSIONS A substantial PD-L1 expression alteration was observed, resulting in low concordance rate before and after NAC-DCF. Tumors persistently lacking PD-L1 had distinct gene expression profile with worse clinical outcomes, raising the need for further investigation.

Abstract
Esophageal cancer (EC) is one of the fatal malignant neoplasms worldwide. Neoadjuvant therapy (NAT) combined with surgery has become the standard treatment for locally advanced EC. However, the treatment efficacy for patients with EC who received NAT varies from patient to patient. Currently, the evaluation of efficacy after NAT for EC lacks accurate and uniform criteria. Radiomics is a multi-parameter quantitative approach for developing medical imaging in the era of precision medicine and has provided a novel view of medical images. As a non-invasive image analysis method, radiomics is an inevitable trend in NAT efficacy prediction and prognosis classification of EC by analyzing the high-throughput imaging features of lesions extracted from medical images. In this literature review, we discuss the definition and workflow of radiomics, the advances in efficacy prediction after NAT, and the current application of radiomics for predicting efficacy after NAT.

Abstract
PURPOSE To clarify the utility of the area of residual tumor for patients with esophageal squamous cell cancer treated with neoadjuvant chemotherapy. METHODS We enrolled 186 patients with esophageal squamous cell cancer who underwent surgical resection following neoadjuvant chemotherapy at our hospital. Using digital images, we measured the area of residual tumor at the maximum plane of the specimen and divided the patient into three groups as follows: 0 (area = 0 mm2), low (area = 0-40 mm2), and high (area ≥ 40 mm2). The clinicopathological factors and prognosis were compared among these groups. RESULTS The median area of the residual tumor was 15.0 mm2 (range 0-1,448.8 mm2). Compared with the 0 and low group, the high group was significantly associated with poorer recurrence-free survival (all P < .001) and overall survival (P < .001 [vs. 0] and P = .017 [vs low]). The area of residual tumor, ypN, tumor regression grade, and lymphovascular invasion were independent predictors of recurrence-free survival. By dividing the patients using a combination of the area of residual tumor and lymphovascular invasion, the high and/or lymphovascular invasion ( +) group displayed significantly poor recurrence-free survival than the 0 group and low/lymphovascular invasion ( -) group. However, there was no significant difference in the recurrence-free survival between the 0 group and low/lymphovascular invasion ( -) group. CONCLUSION The area of residual tumor is a promising histopathological prognostic factor for patients with esophageal squamous cell cancer treated with neoadjuvant chemotherapy. Moreover, it is a possible candidate histopathological factor for postoperative chemotherapy selection.

Abstract
BACKGROUND This study aimed to assess the predictive value of tumor regression grade (TRG) and nodal status on survival in esophageal carcinoma with neoadjuvant chemoradiotherapy (nCRT). METHODS Tumor pathologic regression and nodal status were assessed. Differences in survival stratified by TRG or nodal status were analyzed using the Kaplan-Meier method and log-rank test. The prognostic value of TRG and nodal status were analyzed using univariate and multivariate Cox proportional hazards methods. RESULTS From July 2016 to June 2019, 253 patients with esophageal cancer underwent nCRT followed by surgery. Significant differences were presented in survival according to nodal status but not TRG. Multivariate analysis showed that nodal status and not TRG was the only independent predicter for overall survival (HR: 3.550, 95% CI: 2.264-5.566, P < 0.001) and disease-free survival (HR: 2.801, 95% CI: 1.874-4.187, P < 0.001). The modified TRG system combining tumor regression with nodal status stratified patients survival with good discrimination. CONCLUSIONS Lymph node status impacts more importantly than TRG on survival for patients with esophageal cancer undergoing nCRT plus esophagectomy. The modified TRG system may facilitate postoperative treatment decisions and survival surveillance.

Abstract
Background The counts of examined lymph nodes (ELNs) in predicting the prognosis of patients with esophageal squamous cell carcinoma (ESCC) is a controversial issue. We conducted a retrospective study to develop an ELNs-based model to individualize ESCC prognosis. Methods Patients with ESCC from the SEER database and our center were strictly screened. The optimal threshold value was determine by the X-tile software. A prognostic model for ESCC patients was developed and validated with R. The model’s efficacy was evaluated by C-index, ROC curve, and decision curve analysis (DCA). Results 3,629 cases and 286 cases were screened from the SEER database and our center, respectively. The optimal cut-off value of ELNs was 10. Based on this, we constructed a model with a favorable C-index (training group: 0.708; external group 1: 0.687; external group 2: 0.652). The model performance evaluated with ROC curve is still reliable among the groups. 1-year AUC for nomogram in three groups (i.e., 0.753, 0.761, and 0.686) were superior to that of the TNM stage (P < 0.05). Similarly, the 3-year AUC and the 5-year AUC results for the model were also higher than that of the 8th TNM stage. By contrast, DCA showed the benefit of this model was better in the same follow-up period. Conclusion More than 10 ELNs are helpful to evaluate the survival of ESCC patients. Based on this, an improved model for predicting the prognosis of ESCC patients was proposed.

Novel pathological staging for patients with locally advanced esophageal squamous cell carcinoma undergoing neoadjuvant chemotherapy followed by surgery. Esophagus 2022; 19:214-223. [PMID: 34757482 DOI: 10.1007/s10388-021-00891-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 10/19/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND The aim of the present study was to clarify an appropriate staging system for patients with locally advanced esophageal squamous cell carcinoma (LAESCC) after neoadjuvant chemotherapy (NAC) prior to surgery. METHODS A total of 388 patients with clinical stage II or III LAESCC who had undergone NAC followed by an esophagectomy with three-field lymphadenectomy were retrospectively reviewed. RESULTS The relapse-free survival (RFS) curves plotted using ypN grading and ypTNM staging both monotonically decreased as the classification number increased, and the groups were more clearly separated than when the Japanese Classification (JC) was applied. A multivariate analysis of relapse free survival (RFS) suggested that ypN (HR = 2.911, P < 0.001), lymphovascular invasion (LVI) (HR = 2.608, P < 0.001) were independent factors associated with OS. The LVI+/ypN+ group had a significantly poorer outcome than the other groups (P < 0.001). The 5-year RFS rates for patients with ypStage IIIA or higher among the LVI-negative cases and ypStage II or higher among the LVI-positive cases were around 0.6 or under. The novel pathological staging which was based on the present results was proposed and RFS curves of each novel stage suggested the suitability of these staging for our cohort. CONCLUSIONS The present results suggest that a novel pathological staging system using the ypTNM classification, in which the supraclavicular lymph node was regarded as a regional lymph node and the presence of LVI was included as a category, was appropriate for patients with LAESCC after NAC prior to surgery.

Impact of CT-assessed changes in tumor size after neoadjuvant chemotherapy on pathological response and survival of patients with esophageal squamous cell carcinoma. Langenbecks Arch Surg 2022; 407:965-974.

Abstract
PURPOSE Neoadjuvant chemotherapy (NAC) followed by surgery is the standard treatment for advanced esophageal squamous cell carcinoma (ESCC) in Japan. Computed tomography (CT) is usually used to assess the therapeutic effect of NAC; however, there are no reliable criteria for predicting pathological response or patient prognosis. METHODS We included 84 patients who underwent esophagectomy between January 2009 and December 2018 and retrospectively reviewed their CT scans performed before and after NAC. The reduction rate of the largest tumor area (TA), long diameter (LD), and short diameter (SD) were measured on a transverse CT image. The pathological response and cutoff values were calculated using the receiver operating characteristic curve, and the most suitable ones for determining the effect were examined. RESULTS The areas under the curve for predicting responders to NAC based on the reduction rate of the TA, LD, and SD were 0.755, 0.761, and 0.781, respectively. The optimal cutoff value of the SD reduction rate for predicting responders to NAC was 22%. An SD reduction ≥ 22% was an independent prognostic factor for overall survival in univariate (p = 0.005, hazard ratio [HR] = 2.755) and multivariate analyses (p = 0.030 HR 2.690). Furthermore, an SD reduction of ≥ 22% was also an independent prognostic factor for relapse-free survival in the univariate (p = 0.007, HR = 2.491) and multivariate analyses (p = 0.007, HR = 0.030). CONCLUSIONS The reduction rate of the tumor SD is a simple predictor of pathological response and patient prognosis.

Patterns and timing of recurrence in esophageal squamous cell carcinoma patients treated with neoadjuvant chemoradiotherapy plus esophagectomy. BMC Cancer 2021; 21:1192. [PMID: 34753448 PMCID: PMC8576899 DOI: 10.1186/s12885-021-08918-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 10/26/2021] [Indexed: 11/29/2022] Open
Abstract
Background Tumor regression grade (TRG) after neoadjuvant therapy is reportedly predictive of prognosis in esophageal cancer patients, as lack of a response to neoadjuvant therapy is associated with a poor prognosis. However, there is little information available on the timing and pattern of recurrence after esophagectomy for thoracic esophageal squamous cell carcinoma (TESCC) that takes into consideration TRG after neoadjuvant chemoradiotherapy (NACRT). Here, in an effort to gain insight into a treatment strategy that improves the prognosis of NACRT non-responders, we evaluated the patterns and timing of recurrence in TESCC patients, taking into consideration TRG after NACRT. Methods A total of 127 TESCC patients treated with NACRT and esophagectomy between 2009 and 2017 were enrolled in this observational cohort study. TRGs were assigned based on the proportion of residual tumor cells in the area (TRG1, ≥1/3 viable cancer cells; 2, < 1/3 viable cancer cells; 3, no viable cancer cells). We retrospectively investigated the timing and patterns of recurrence and the prognoses in TESCC patients, taking into consideration TRG after NACRT. Results The 127 participating TESCC patients were categorized as TRG1 (42 patients, 33%), TRG2 (56 patients, 44%) or TRG3 (29 patients, 23%). The locoregional recurrence rate was higher in TRG1 (36.4%) patients than combined TRG2–3 (7.4%) patients. Patients with TRG3 had better prognoses, though a few TRG3 patients experienced distant recurrence. There were no significant differences in median time to first recurrence or OS among patients with locoregional or distant recurrence. There was a trend toward better OS in TRG2–3 patients with recurrence than TRG1 patients with recurrence, but the difference was not significant. Conclusions NACRT non-responders (TRG1 patients) experienced higher locoregional recurrence rates and earlier recurrence with distant or locoregional metastasis. TRG appears to be useful for establishing a strategy for perioperative treatments to improve TESCC patient survival, especially among TRG1 patients. (303 words).

Abstract
BACKGROUND Patients with 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET)-positive lymph nodes before treatment have a poor prognosis after esophagectomy. This study investigated whether FDG uptake into lymph nodes on FDG-PET (PET-N) during the pre- or posttreatment stage is more predictive of survival for thoracic esophageal squamous cell carcinoma (TESCC) patients who received neoadjuvant chemoradiotherapy (NACRT) followed by esophagectomy. METHODS Of 129 TESCC patients with clinical lymphatic metastasis who underwent curative-intent esophagectomy after NACRT between 2010 and 2018, 97 who received PET before and after NACRT were enrolled in the study. The study defined lymph nodes with a maximum standardized uptake value (SUVmax) greater than 2.5 on FDG-PET before NACRT as cPET-N(+) and after NACRT as CRT-cPET-N(+). Both the cPET-N(+) and CRT-cPET-N(-) patients were defined as PET-N responders. Survival was analyzed using the Kaplan-Meier method and Cox proportional hazard models. RESULTS No significant difference in survival was detected between the cPET-N(+) and cPET-N(-) patients. However, the CRT-cPET-N(-) patients had significantly better 5-year overall survival (OS) and disease-specific survival (DSS) than the CRT-cPET-N (+) patients. The PET-N responders had significantly better 5-year OS and DSS than the PET-N non-responders, and PET-N response was an independent prognostic factor for 5-year DSS. CONCLUSION The PET-N response is a highly predictive prognostic marker for TESCC patients who undergo NACRT followed by esophagectomy. The PET-N response may help clinicians to establish a strategy for perioperative treatments that improves survival for patients with lymph node metastasis in TESCC.

Abstract
BACKGROUND Lymph node metastasis is one of the pivotal factors of the clinical outcomes of patients with esophageal cancer receiving neoadjuvant chemoradiation therapy (NACRT). Both the nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling pathway and heme oxygenase-1 (HO-1) are frequently upregulated in various human malignancies and associated with resistance to chemoradiation therapy, subsequently resulting in adverse clinical outcomes. However, the Nrf2 and HO-1 status in lymph node metastasis and their differences between primary and metastatic lesions are unknown. AIMS To examine the levels of Nrf2 signaling proteins and HO-1 in primary and metastatic lesions of patients with esophageal squamous cell carcinoma using immunohistochemistry. METHODS AND RESULTS We immunolocalized Nrf2 signaling proteins in 69 patients with lymph node metastases, who received NACRT with 5-fluorouracil and cisplatin before esophagectomy. We also compared the findings between primary and metastatic lesions. Residual lymph node metastases were detected in 30 patients and among them, both primary and metastatic lesions were available for evaluation in 25 patients. Subsequently, we correlated the results with patients' survival. Nrf2, HO-1, and the Ki-67 labeling index were all significantly lower in the patients with lymph node metastases than in those with primary tumors. Carcinoma cells with high HO-1 levels were significantly associated with pathological resistance to NACRT. These results suggested that overall and disease-free survival of esophageal squamous cell carcinoma were significantly associated with both pN2 and high HO-1 levels, respectively. CONCLUSIONS Protein expression in the Nrf2 pathway was significantly lower in patients with lymph node metastases than in those with primary lesions. HO-1 levels in lymph node metastases could be used to predict the eventual clinical outcome of patients with esophageal cancer receiving NACRT.

Abstract
BACKGROUND AND OBJECTIVES A standardized data set for esophageal carcinoma pathology reporting was developed based on the approach of the International Collaboration on Cancer Reporting (ICCR) for the purpose of improving cancer patient outcomes and international benchmarking in cancer management. MATERIALS AND METHODS The ICCR convened a multidisciplinary international expert panel to identify the best evidence-based clinical and pathological parameters for inclusion in the data set for esophageal carcinoma. The data set incorporated the current edition of the World Health Organization Classification of Tumours of the Digestive System, and Tumour-Node-Metastasis staging systems. RESULTS The scope of the data set encompassed resection specimens of the esophagus and esophagogastric junction with tumor epicenter ≤20 mm into the proximal stomach. Core reporting elements included information on neoadjuvant therapy, operative procedure used, tumor focality, tumor site, tumor dimensions, distance of tumor to resection margins, histological tumor type, presence and type of dysplasia, tumor grade, extent of invasion in the esophagus, lymphovascular invasion, response to neoadjuvant therapy, status of resection margin, ancillary studies, lymph node status, distant metastases, and pathological staging. Additional non-core elements considered useful to report included clinical information, specimen dimensions, macroscopic appearance of tumor, and coexistent pathology. CONCLUSIONS This is the first international peer-reviewed structured reporting data set for surgically resected specimens of the esophagus. The ICCR carcinoma of the esophagus data set is recommended for routine use globally and is a valuable tool to support standardized reporting, to benefit patient care by providing diagnostic and prognostic best-practice parameters.

[PMID: 33981339 PMCID: PMC8088378 DOI: 10.1155/2021/5563136] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 04/07/2021] [Accepted: 04/13/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND AND AIMS Due to the difficulty in clinical staging, a simple and feasible perioperative assessment approach for guiding personalized neoadjuvant chemotherapy (NAC) is lacking. We investigated the clinical value of NAC in advanced gastric carcinoma (GC) and the concordance between perioperative imaging and postoperative pathological assessments. METHODS This study included 62 patients with advanced GC who received NAC between January 2012 and December 2018. The preoperative and postoperative T stages, postoperative pathological tumor regression grade (TRG), and changes in computed tomography (CT) values after NAC were assessed. Follow-ups were conducted to obtain the median survival time (MST), and Kaplan-Meier survival curves were plotted. RESULTS The T stages significantly differed between before and after NAC (p = 0.001). The MST of patients in the TRG0 group was significantly different from that of patients in the TRG1+2 and TRG3 groups (p = 0.223). The percentages of positive lymph nodes were 0%, 24.17%, and 27.64% in the TRG0, TRG1+2, and TRG3 groups, respectively. TRG was correlated with changes in CT values before and after NAC, and the extent of change was associated with patient prognosis. CONCLUSIONS Perioperative imaging can be used to assess the short-term effectiveness of NAC for patients with GC.

SUV max reduction predicts long-term survival in patients of non-pCR both in the tumor and lymph nodes after neoadjuvant chemoradiotherapy in esophageal squamous cell carcinoma. World J Surg Oncol 2021; 19:105. [PMID: 33836789 PMCID: PMC8035772 DOI: 10.1186/s12957-021-02208-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 03/19/2021] [Indexed: 12/20/2022] Open
Abstract
Background A pathological complete response (pCR) after neoadjuvant chemoradiotherapy (NACRT) ensures long-term survival in esophageal squamous cell carcinoma (ESCC) patients following esophagectomy, but pCR patients are a minority. The aim here was to identify prognostic factors in patients with non-pCR ESCC after NACRT. Methods This is a retrospective study. Investigated were 5-year overall survival (OS), disease-specific survival (DSS), and relapse-free survival (RFS) among non-pCR ESCC patients divided into pT0N0, primary site pCR (pT0N+), lymph node pCR (pT+N0), and non-pCR in both the tumor and lymph node (pT+N+) subgroups after NACRT and esophagectomy. Focusing on the SUVmax reduction rate in the primary tumor in 88 patients who underwent FDG-PET before and after NACRT, we used univariate and multivariate Cox proportional hazard models to identify prognostic factors. Results Although there were no significant survival differences among non-pCR ESCC patients with pT0N+, pT+N0, or pT+N+, survival rate among pT+N+patients was the poorest. After setting a 60% cutoff for the SUVmax reduction rate in the tumor, RFS curves for non-pCR patients significantly differed between patients above the cutoff and those below it. For pT+N+ patients, the SUVmax reduction rate (<60% vs ≥ 60%) was an independent prognostic factor of OS, DSS, and RFS. Conclusion Because ESCC patients with SUVmax reduction rates of <60% in the tumor after NACRT and categorized as pT+N+ after NACRT had significantly poorer prognoses, even after esophagectomy, a change in treatment strategy may be an option to improve survival.

Abstract
Background Neoadjuvant chemoradiotherapy (NCRT) plus surgery is the standard treatment for esophageal squamous cell carcinoma (ESCC); however, further analysis is needed to detail the histopathological characteristics of ESCC and their clinical significance after NCRT. This study aimed to present the pathological characteristics of ESCC and their association with prognosis after NCRT. Methods All patients with ESCC who underwent NCRT followed by surgical resection at Sichuan Cancer Hospital (China) from January 2018 to December 2019 were included. Resection specimens of both the primary disease and lymph nodes were re-evaluated by an experienced pathologist. After NCRT, the pathological characteristics of the residual tumor were evaluated based on the Japanese residual tumor pattern, Mandard tumor regression grade (Mandard-TRG), local inflammatory infiltration classification, and lymph node status. Results Among the 103 patients with ESCC included in this study, the pathological complete response (pCR) rate was 34% (35/103). The pCR rate of patients with poorly differentiated tumors (31/72) was higher (43.1%) than that of patients with well or moderately differentiated tumors (P<0.05). The residual tumor rate was 66% (68/103). A positive correlation was noted between the Japanese residual tumor pattern and Mandard-TRG (Kendall’s tau-b =0.857, P<0.001). Tumor infiltration depth, lymph node positivity, moderate differentiation, and tumor recurrence were associated with poor oncological outcomes (P<0.05). Conclusions Patients with poorly differentiated tumors can obtain an excellent short-term response; however, they have extremely poor long-term survival. For patients with moderately differentiated tumors, both the short- and long-term outcomes are poor. Lymph node status after NCRT is a prognostic factor for ESCC treated with NCRT.

Prognostic value of visual residual tumour cells (VRTC) for patients with esophageal squamous cell carcinomas after neoadjuvant therapy followed by surgery. BMC Cancer 2021; 21:111. [PMID: 33535987 PMCID: PMC7860028 DOI: 10.1186/s12885-020-07779-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Accepted: 12/29/2020] [Indexed: 01/03/2023] Open
Abstract
Background We assessed visual residual tumour cells (VRTC) with both Becker’s tumour regression grading (TRG) system and Japanese TRG system in esophageal squamous cell carcinoma (ESCC) patients treated with neoadjuvant therapy followed by surgery. Methods We compared Becker system and Japanese system in 175 ESCC patients treated between 2009 and 2015. Results According to Becker system, the 5-year DFS/DSS rates were 70.0%/89.3, 53.8%/56.7, 43.0%/49.0, and 42.4%/39.1% for TRG 1a (VRTC 0), TRG 1b (1–10%), TRG 2 (11–50%), and TRG 3 (> 50%). According to Japanese system, the rates were 38.8%/34.1, 49.5%/58.7, 50.2%/49.0 and 70.0%/89.3% for Grade 0-1a (VRTC> 66.6%), Grade 1b (33.3–66.6%), Grade 2 (1–33.3%) and Grade 3 (0). TRG according to two systems significantly discriminate the patients’ prognosis. TRG according to Becker system (HR 2.662, 95% CI 1.151–6.157), and lymph node metastasis (HR 2.567, 95% CI 1.442–4.570) were independent parameters of DSS. Conclusions Both Becker and Japanese system had their advantage in risk stratification of these ESCC patients. It was speculated that dividing 1–10% VRTC into a group might contribute to independently prognostic significance of Becker’s TRG system. Therefore, in addition to TRG of different systems, the percentage of VRTC might be recommended in the pathologic report, which could make the results more comparable among different researches, and more understandable for oncologists in the clinical practice.

Abstract
OBJECTIVES Neoadjuvant chemotherapy (nCT) followed by surgery is one of the standard treatments for resectable esophageal squamous cell carcinoma (ESCC). According to the Response Evaluation Criteria in Solid Tumors, endoscopic evaluation of a primary lesion is not recommended during nCT because of reduced objectivity. This study aimed to develop and validate endoscopic evaluation criteria for nCT. METHODS This study retrospectively investigated patients with T2/3 ESCC who underwent nCT followed by radical esophagectomy across two institutions (test and validation sets). We retrospectively estimated the therapeutic effect by classifying patients according to degree of tumor shrinkage (evaluated with endoscopy) as follows: marked reduction (MR), half reduction (HR), insufficient reduction (IR), and progressive disease (PD). Three endoscopists evaluated patients in the test set. Another three endoscopists evaluated patients in the validation set. We analyzed recurrence-free survival (RFS) 3 years after surgery. RESULTS Of 129 patients in the test set, 44 had MR, 35 had HR, 44 had IR, and six had PD. The 3-year RFS rates were 55% (overall), 79% (MR), 54% (HR), 35% (IR), and 33% (PD). Of 91 patients in the validation set, 22 had MR, 49 had HR, 18 had IR, and two had PD. The 3-year RFS rates were 54% (overall), 77% (MR), 55% (HR), 22% (IR), and 50% (PD). CONCLUSIONS Our endoscopic criteria for nCT predicted prognosis; however, future studies are needed to further investigate our criteria before general application in the clinical setting.

Abstract
BACKGROUND AND AIM Clinical significance of endoscopic response (ER) after neoadjuvant chemotherapy (NAC) for esophageal cancer has not been fully understood. Thus, the present study aimed to investigate the association between ER to NAC and its clinicopathological outcomes in patients with esophageal squamous cell carcinoma (ESCC). METHODS In total, 141 patients who underwent NAC and subsequent esophagectomy for ESCC were included. ER to NAC was retrospectively evaluated based on macroscopic findings of the primary tumor, which was classified into three categories: endoscopic no response (eNR), endoscopic partial response (ePR), and endoscopic good response (eGR). An endoscopic responder was defined as patients with eGR/ePR. RESULTS Approximately 89.4% of patients had cStage II-III disease, and 7.1% had pathological complete response. Upon ER evaluation, eNR, ePR, and eGR were observed in 46 (32.6%), 54 (38.3%), and 41 (29.1%) patients, respectively. Pathological responders significantly increased as the ER grade became better. Among preoperative clinical factors, only ER significantly correlated with pathological response in univariate and multivariate analysis. Endoscopic responders showed a significantly better prognosis than did eNR patients (P < 0.001), although the overall survival (OS) of the patients with eGR and ePR was equivalent. Endoscopic responder, ypT, ypN, and pathological responder were significant predictors of OS in the univariate analysis, and endoscopic responder, ypN, and pathological responder were independent predictors in the multivariate analysis. CONCLUSION This study suggests that ER can be a simple and important tool to predict the pathological response and survival of patients who undergo NAC for ESCC.

Abstract
BACKGROUND The present study investigated prognostic factors in patients with resectable locally advanced esophageal squamous cell carcinoma (ESCC) among various clinicopathological features related to neoadjuvant chemotherapy (NAC) and surgery, and the indications for additional treatment after surgery were considered. METHODS A total of 113 patients with clinical stage II or III ESCC, who had undergone NAC followed by a thoracic esophagectomy with a three-field lymphadenectomy were retrospectively reviewed. NAC consisted of either two courses of cisplatin and 5-fluorouracil or three courses of docetaxel, cisplatin and 5-fluorouracil, with a new course beginning every 3 weeks. RESULTS The overall survival (OS) rate was poorer in the pN-positive group than in the pN-negative group (P < 0.001). In terms of the histological therapeutic effect, the OS rate was poorer in the worse pathological responder group than in the better pathological responder group (P = 0.001). A multivariate analysis examining overall survival suggested that only pN (HR 3.204, P = 0.007) and worse pathological responder (HR 2.347, P = 0.041) were independent prognostic factors. The OS rate was compared among four groups classified according to the different combinations of pN and pathological response. A group of patients with pN-positive and worse pathological response had a significantly poorer outcome than the other groups. CONCLUSIONS The present study suggested that patients with resectable advanced ESCC undergoing NAC followed by surgery, who have both pN and worse pathological response, have a poor prognosis.

Abstract
BACKGROUND Neoadjuvant therapy (NAT) before radical excision has become the preferred initial option for locally advanced digestive cancers such as esophageal cancer (EC), esophagogastric junction adenocarcinoma (EGJAC), gastric adenocarcinoma (GAC), rectal cancer (RC), and pancreatic cancer (PC). Although some patients reportedly achieve a pathologic complete response (pCR) after neoadjuvant therapy, the published data are inconsistent regarding whether pCR yields a survival benefit. The current meta-analysis was performed to assess the potential prognostic value of pCR after preoperative therapy for patients with digestive cancers. METHODS An extensive electronic search in PubMed, Web of Science, and the Cochrane Library was performed for relevant articles, from which data relative to independent correlations of pCR with overall survival (OS) and disease-free survival (DFS) were extracted for analysis. A random-effects model was used to calculate the pooled hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs). RESULTS The study identified 6780 patients who met the inclusion and exclusion criteria. The results showed that pCR was significantly correlated with better OS (HR, 0.50; 95% CI, 0.43-0.58; P < 0.001) and DFS (HR, 0.49; 95% CI, 0.40-0.60; P < 0.001) for the digestive cancer patients who achieved pCR than for those who did not achieve pCR. Subgroup analysis showed that the correlation of pCR with OS was significant in EC (HR, 0.57; 95% CI, 0.47-0.69; P < 0.001), EGJAC/GAC (HR, 0.38; 95% CI, 0.17-0.86; P = 0.02), RC (HR, 0.48; 95% CI, 0.28-0.81; P = 0.006), and PC (HR, 0.41; 95% CI, 0.17-0.97; P = 0.04). In addition, the survival benefit for pCR patients was of similar magnitude, irrespective of the type of study, type of NAT, or ethnicity. CONCLUSIONS A pCR is correlated with favorable survival outcomes compared with a non-pCR for digestive cancer patients after NAT.

[PMID: 29465751 PMCID: PMC5969086 DOI: 10.1111/his.13491] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Accepted: 02/14/2018] [Indexed: 12/19/2022]
Abstract
AIMS Neoadjuvant chemotherapy (NAC) remains an important therapeutic option for advanced oesophageal cancer (OC). Pathological tumour regression grade (TRG) may offer additional information by directing adjuvant treatment and/or follow-up but its clinical value remains unclear. We analysed the prognostic value of TRG and associated pathological factors in OC patients enrolled in the Medical Research Council (MRC) OE02 trial. METHODS AND RESULTS Histopathology was reviewed in 497 resections from OE02 trial participants randomised to surgery (S group; n = 244) or NAC followed by surgery [chemotherapy plus surgery (CS) group; n = 253]. The association between TRG groups [responders (TRG1-3) versus non-responders (TRG4-5)], pathological lymph node (LN) status and overall survival (OS) was analysed. One hundred and ninety-five of 253 (77%) CS patients were classified as 'non-responders', with a significantly higher mortality risk compared to responders [hazard ratio (HR) = 1.53, 95% confidence interval (CI) = 1.05-2.24, P = 0.026]. OS was significantly better in patients without LN metastases irrespective of TRG [non-responders HR = 1.87, 95% CI = 1.33-2.63, P < 0.001 versus responders HR = 2.21, 95% CI = 1.11-4.10, P = 0.024]. In multivariate analyses, LN status was the only independent factor predictive of OS in CS patients (HR = 1.93, 95% CI = 1.42-2.62, P < 0.001). Exploratory subgroup analyses excluding radiotherapy-exposed patients (n = 48) showed similar prognostic outcomes. CONCLUSION Lymph node status post-NAC is the most important prognostic factor in patients with resectable oesophageal cancer, irrespective of TRG. Potential clinical implications, e.g. adjuvant treatment or intensified follow-up, reinforce the importance of LN dissection for staging and prognostication.

Cancer Sci 2018; 109:2046-2055. [PMID: 29601131 PMCID: PMC5989742 DOI: 10.1111/cas.13596] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 03/19/2018] [Accepted: 03/22/2018] [Indexed: 11/28/2022] Open
Abstract
Tumor regression grade of the primary tumor (TRG‐PT) and residual lymph node metastasis have been pathologically determined in esophageal squamous cell carcinoma (ESCC) patients who had received neoadjuvant chemotherapy (nCT) followed by surgery; however, TRG of the metastatic tumor involving lymph nodes (LN) has not yet been determined. The aim of the present study was to clarify the impact of TRG on the prognosis of ESCC patients. ESCC patients (n = 110) who had received nCT followed by surgery were enrolled. Dissected LN were classified into 2 categories: plausible positive metastatic LN (pp‐MLN) where viable and/or degenerated ESCC cells and/or tissue modifications were observed, and non‐metastatic LN (non‐MLN) where neither of them was observed. We defined nCT‐effective rate (CER) as the ratio of the number of pp‐MLN that showed tumor regression to the total number of pp‐MLN, and divided CER into low‐CER (LCER; ≥0% and <50%) and high‐CER (HCER; ≥50% and ≤100%). Relationships between CER and clinicopathological factors including prognosis were then examined. Multivariate analyses of 110 patients indicated that ypT3‐4 (P = .023, HR; 2.551), positive venous infiltration (P = .006, HR; 3.526), and LCER (P = .033, HR; 1.922) were independently associated with shorter recurrence‐free survival (RFS). Multivariate analyses of 43 patients with grade 0 TRG‐PT showed that ypT3‐4 (P = .033, HR; 3.397) and LCER (P = .008, HR; 3.543) were independently associated with shorter RFS. This study showed that CER was one of the prognostic factors for ESCC patients who had received nCT followed by surgery.

Treatment Strategies and Prognostic Factors of Limited-Stage Primary Small Cell Carcinoma of the Esophagus. J Thorac Oncol 2017; 12:1834-1844. [PMID: 29024756 DOI: 10.1016/j.jtho.2017.09.1966] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2017] [Revised: 09/19/2017] [Accepted: 09/21/2017] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Primary small cell carcinoma of the esophagus (PSCCE) is characterized by high malignancy, early metastasis, and poor prognosis. This retrospective study aimed to review the clinical characteristics of patients with limited-stage PSCCE and determine the relevant prognostic factors and optimal treatment strategies. METHODS We retrospectively evaluated 152 consecutive patients with limited-stage PSCCE between January 2007 and December 2015. Prognostic factors were analyzed using univariate analysis and a Cox regression model. Subgroup analysis was applied to evaluate the effect of treatment strategy on survival. RESULTS Univariate and multivariate analyses showed that treatment modality (p = 0.034) and N stage (p = 0.002) were independent prognostic factors. Patients with stage I or IIA PSCCE who underwent an operation alone exhibited better survival than those who did not undergo an operation (median survival time 29 versus 17.4 months [p = 0.031]), and postoperative adjuvant therapy did not increase overall survival or disease-free survival (p > 0.05). The overall survival rate of patients with stage III PSCCE who underwent neoadjuvant chemotherapy (nCT) was significantly better than that of patients who underwent an operation alone or did not undergo an operation (p = 0.021 and p = 0.026, respectively); additionally, nCT could increase disease-free survival (p = 0.031). CONCLUSIONS Treatment modalities and N stage are independent prognostic factors. Radical esophagectomy should be considered as the primary treatment for stage I or IIA PSCCE, and nCT followed by esophagectomy could be an effective treatment option for stage III PSCCE. Multicenter randomized studies are required to confirm the role of nCT in the management of limited-stage PSCCE.

Failure of neoadjuvant chemotherapy for resectable esophageal squamous cell carcinoma. Dis Esophagus 2017; 30:1-8.

Abstract
Neoadjuvant treatment has become standard care for patients with resectable esophageal cancer. However, some patients cannot undergo surgery or curative resection because of disease progression during neoadjuvant treatment. The aim of this study is to identify the pretreatment characteristics of patients in whom neoadjuvant treatment failed. The study enrolled 231 patients who underwent chemotherapy with cisplatin and 5-fluorouracil (CF) as neoadjuvant therapy for T1N1-3 or T2-3 any-N esophageal squamous cell carcinoma (ESCC). Of these patients, 201 (87.0%) underwent curative resection (R0) and 30 (13.0%) could not undergo curative resection; 19 patients (8.2%) underwent incomplete resection (R1 or R2), and 11 patients (4.8%) could not undergo surgery because of disease progression. We compared clinical characteristics and survival between patients who underwent curative resection (curative group) and those who could not undergo curative resection (noncurative group) to determine the factors predicting noncurative treatment. The noncurative group had significantly worse disease-specific survival than the curative group (P < 0.001). All patients in the noncurative group had cT3 tumors. In 141 patients with cT3 tumors, those in the noncurative group were more likely to have higher serum SCC antigen concentration (P = 0.021), location of the main tumor in the upper to the middle third of the esophagus (P = 0.071), intramural metastases (P < 0.001), advanced N category (P = 0.016), and bulky lymph node metastases (P = 0.060). Multivariate logistic regression analysis identified location of the main tumor in the upper to the middle third of the esophagus (P = 0.047), intramural metastases (P = 0.002), and nodal metastases (N1, P = 0.014; N2, P = 0.015, respectively) as independent predictors of treatment failure in patients with cT3 tumors. Neoadjuvant CF therapy alone may not be effective for patients with cT3 tumors accompanied by these risk factors, and the efficacy of alternative strategies, such as triplet chemotherapy or chemoradiotherapy, should be evaluated.
