Abstract
Background Systemic inflammation response is a crucial prognostic factor for various cancers. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are two inflammation-based prognostic scores. The significance of preoperative NLR and PLR in patients with esophageal squamous cell carcinoma (ESCC) receiving curative esophagectomy remains largely undefined. Hence, this study aimed to evaluate the significance of preoperative NLR and PLR in patients with ESCC receiving curative esophagectomy in southern Taiwan. Methods A consecutive group of 107 patients with ESCC undergoing esophagectomy between January 2001 and December 2012 were retrospectively reviewed. The NLR and PLR of these 107 patients were calculated and correlated with clinicopathological parameters, overall survival (OS), and disease-free survival (DFS). Results NLR ≥2.5 was significantly correlated with higher T classification (P=0.006) and advanced clinical AJCC 7th stage (P=0.047). PLR ≥150 was significantly associated with higher T classification (P=0.009). Univariate survival analysis showed that NLR ≥2.5 and PLR ≥150 were associated with poor OS (P=0.009 and P=0.007, respectively) and poor DFS (P=0.006 and P=0.005, respectively). On multivariate comparison, PLR ≥150 was independently associated with poor OS [P=0.001, hazard ratio (HR): 2.475] and poor DFS (P<0.001, HR: 2.509). The 5-year overall and DFS rates were, respectively, 33.3% and 25.0% in patients with PLR ≥150, and 54% and 46% in patients with PLR <150. Conclusions The PLR is an independent prognosticator for patients with ESCC undergoing esophagectomy in southern Taiwan.

An actin-binding protein ESPN is an independent prognosticator and regulates cell growth for esophageal squamous cell carcinoma. Cancer Cell Int 2018; 18:219.

Abstract
Background ESPN (Espin), an actin filament-binding protein, plays an important role in regulating the organization, dimensions, dynamics, and signaling capacities of the actin filament-rich, microvillus-type specializations that mediate sensory transduction in various mechanosensory and chemosensory cells. Recent few studies show that ESPN regulates metastasis and cell proliferation in melanoma. However, the significance of ESPN in other cancers such as esophageal squamous cell carcinoma (ESCC) remains largely unknown. Methods Immunohistochemistry was performed in 169 patients with ESCC and correlated with clinicopathological features and survival. The functional role of ESPN in ESCC cells was determined by ESPN-mediated siRNA. Results Univariate analyses showed that high ESPN expression was associated with inferior overall survival (P = 0.005) and disease-free survival (P = 0.035). High ESPN expression was an independent prognosticator in multivariate analysis for overall survival (P = 0.009, hazard ratio = 1.688) and disease-free survival (P = 0.049, hazard ratio = 1.451). The 5-year overall survival rates were 30% and 54% in patients with high and low expression of ESPN, respectively. Inhibition of endogenous ESPN in ESCC cells decreased ESCC growth by reducing cell proliferating rates. Conclusions High ESPN expression is independently associated with poor prognosis in patients with ESCC and downregulation of ESPN inhibits ESCC cell growth. Our results suggest that ESPN may be a novel therapeutic target for patients with ESCC.

Abstract
Background Resection remains the best treatment for carcinoma of the esophagus in terms of local control, but local recurrence and distant metastasis remain an issue after surgery. Chemo-radiotherapy (CRT) followed by surgery was associated with significantly improved survival benefit, but the effectiveness of neoadjuvant therapy in patients with resectable esophageal carcinoma remains controversial. The aim of this study was to evaluate the effects of neoadjuvant chemoradiotherapy in resectable esophageal carcinoma compared to surgery alone (SA). Methods A search for publications that compared the efficacy of CRT with SA in resectable esophageal carcinoma was conducted. After a rigorous review of the quality, the data were extracted from eligible trials. The major outcomes measures were odds ratios (ORs). The ORs with their corresponding 95% confidence intervals were the principal measure of effects. For the meta-analysis, Revman 5.3 software was used to analyze the combined pooled ORs using fixed- or random-effects models according to the heterogeneity. Results Our findings revealed that, compared with SA, neoadjuvant CRT was associated with improved overall survival (OS) and progression-free survival times, but the 3- and 5-year OS did not show a statistical difference (P≥0.05). The adjuvant chemotherapy group did not show significant improvement on reference rate and metastasis rate compared with the control group. Conclusion CRT does significantly improve progression-free survival and OS in patients with esophageal cancer compared with SA. However, further assessment is still warranted on the role of CRT in future trials with well-selected patients.

Abstract
AIM: To define the benefits of three-dimensional video-assisted thoracoscopic esophagectomy (3D-VATE) over 2D-VATE for esophageal cancer.
METHODS: A total of 93 patients with esophageal cancer including 45 patients receiving 3D-VATE and 48 receiving 2D-VATE were evaluated. Data related to patient and cancer characteristics, operating time, intraoperative bleeding, morbidity and mortality, postoperative inflammatory markers, Numerical Rating Scale for postoperative pain, Constant-Murley rating system for shoulder recovery and oxygenation index (OI) were collected. All medical records were retrieved from a prospectively maintained oncological database at our institution. A retrospective study was performed to compare the short-term surgical outcomes between the two groups.
RESULTS: No significant differences were found between the two groups in either morbidity or mortality (P = 0.328). An enhanced surgical recovery was noted in the 3D group as indicated by shortened thoracoscopic operation time (3D vs 2D: 68 ± 13.79 min vs 83 ± 13 min, P < 0.01), minor intraoperative blood loss (3D vs 2D: 68.2 ± 10.7 mL vs 89.8 ± 10.4 mL, P < 0.01), earlier chest tube removal (3D vs 2D: 2.67 ± 1.01 vs 3.75 ± 1.15 d, P < 0.01), shorter length of hospital stay (3D vs 2D: 9.07 ± 2.00 vs 10.85 ± 3.40 d, P < 0.01), lower in-hospital expenses (3D vs 2D: 74968.4 ± 9637.8 vs 86211.1 ± 8519.7 RMB, P < 0.01), lower pain intensity (P < 0.01) and faster recovery of the left shoulder function (P < 0.01). Better preservation of the pulmonary function was also found in the 3D group as the decline of the OI post operation was significantly lower than that of the 2D group (P < 0.01). Changes of postoperative inflammatory markers, including procalcitonin [postoperative days (PODs) 4 and 7: P < 0.01], peripheral granulocytes (PODs 1, 4 and 7: P < 0.01) and hypersensitive C-reactive protein (POD 4: P < 0.01) in 3D-VATE patients were less than those in the 2D group. Moreover, utilization of the 3D technique extended the dissection of the thoracic lymph nodes (P < 0.01), with better exposure of nodes in the left recurrent laryngeal nerve (P = 0.031).
CONCLUSION: 3D-VATE could be a more viable technique over 2D-VATE in terms of short-term outcomes for patients with esophageal cancer.

Phosphorylated p70S6K expression is an independent prognosticator for patients with esophageal squamous cell carcinoma. Surgery 2014; 157:570-80.

Abstract
BACKGROUND Although marked improvements have been made in surgical technique and chemoradiotherapy, the prognosis for patients with esophageal squamous cell carcinoma (ESCC) is still unsatisfactory. The mammalian target of rapamycin (mTOR) and its downstream signaling, p70 ribosomal S6 protein kinase (p70S6K) and eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1), seem to play central roles in the regulation of cancer cell proliferation and survival. The significance of mTOR and its downstream targets, p70S6K and 4E-BP1, on the prognosis of ESCC remains uncertain, but this pathway is of particular concern because effective inhibitors are already available. METHODS Immunohistochemistry performed to evaluate the expression of phosphorylated mTOR (p-mTOR), phosphorylated p70S6K (p-p70S6K), phosphorylated 4E-binding protein 1 (p-4E-BP1), and Ki-67 using 105 surgically resected ESCC correlated with treatment outcome. The effect of the mTOR signaling pathway inhibitor everolimus on ESCC cell lines were investigated in vitro by the 3-(4.5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and in vivo by a nude mouse xenograft model. RESULTS Univariate analysis showed that p-mTOR overexpression (P = .022), p-p70S6K overexpression (P = .002), and Ki-67 labeling index >50% (P = .045) were associated with inferior overall survival (OS). In a multivariate comparison, p-p70S6K overexpression (P = .001; hazard ratio, 2.247) remained independently associated with worse OS. In cell lines and the xenograft model, everolimus significantly inhibited ESCC growth. CONCLUSION Overexpression of p-p70S6K is associated independently with a poor prognosis among patients with ESCC. The mTOR signaling pathway inhibitor everolimus can inhibit ESCC growth in vitro and in vivo. Our findings suggest that inhibition of mTOR signaling pathway may be a promising novel target for ESCC.

Chemoradiotherapy, with adjuvant surgery for local control, confers a durable survival advantage in adenocarcinoma and squamous cell carcinoma of the oesophagus. Eur J Cancer 2014; 50:1065-75. [PMID: 24480403 DOI: 10.1016/j.ejca.2013.12.022] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2013] [Revised: 12/18/2013] [Accepted: 12/31/2013] [Indexed: 01/20/2023]
Abstract
INTRODUCTION Oesophageal cancer usually presents with systemic disease, necessitating systemic therapy. Neo-adjuvant chemoradiotherapy improves short-term survival, but its long-term impact is disputed because of limited accrual, treatment-protocol heterogeneity and a short follow-up of randomised trials. AIMS Long-term results of two simultaneous randomised controlled trials (RCTs) comparing neo-adjuvant chemo-radiotherapy and surgery (MMT) with surgical monotherapy were examined, and the response of adenocarcinoma (AC) and squamous cell carcinoma (SCC) to identical regimens compared. METHODS Between 1990 and 1997, two RCTs were undertaken on 211 patients. Patients with AC (n=113) or SCC (n=98) were separately-randomised to identical protocols of MMT or surgical monotherapy. RESULTS 211 patients were followed to 206 months; 104 patients were randomised to MMT (58 AC and 46 SCC, respectively) and 107 to surgery. MMT provided a significant survival-advantage over surgical monotherapy for AC (P=0.004), SCC (P=0.01). There was a 54% relative risk-reduction in lymph-node metastasis following MMT, compared with surgery (64% versus 29%, P<0.001). MMT produced a pathologic complete response (pCR) in 25% and 31% of AC and SCC, respectively. Survival advantage accrued to MMT, pCR and node-negative patients: AC pCR versus surgical monotherapy (P=0.001); residual disease following MMT versus surgical monotherapy (P=0.008); SCC pCR versus surgical monotherapy (P=0.033). CONCLUSIONS A survival advantage for MMT persisted long-term in AC and was replicated in SCC. MMT produced loco-regional tumour down-staging to extinction in 25-31% of patients, potentially permitting personalised treatment in this cohort that avoids the morbidity and mortality associated with resection. Node-negative patients with residual localised disease following MMT had a survival advantage over node-negative patients following surgery alone, supporting a systemic effect on micro-metastatic disease.

Abstract
Background The chemokine CXCL12 and its receptor CXCR4 play a major role in tumor invasion, proliferation and metastasis in different malignant diseases, including esophageal carcinoma, amongst others. CXCR7 was recently identified as a novel alternate receptor for CXCL12. The aim of this study was to evaluate the prognostic impact of expression of chemokine receptor CXCR7 in patients with esophageal carcinoma (EC). Methods Expression of CXCR7 in primary tumors, lymph nodes and distant metastases of 299 patients with EC was evaluated by immunohistochemistry on a tissue microarray and compared with clinical and histopathological data. Results In esophageal cancer sections, CXCR7-specific reactivity was apparent in 45% of the squamous cell carcinomas (ESCC), but only occasionally in adenocarcinomas. No correlation between CXCR4 and CXCR7 expression was evident. We correlated expression with clinical and histopathological characteristics, but could not find any association. Conclusions Contrary to the other known CXCL12 receptor, CXCR4, CXCR7 is expressed in ESCC only, underlining the divergent mechanisms and backgrounds of EAC and ESCC. The results of the study do not indicate a significant functional role for CXCR7 in EAC or ESCC of the esophagus. However, its variable expression in the main two main types of EC needs to be further investigated.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (NACRT) for esophageal squamous cell carcinoma (ESCC) is beneficial in the setting of a complete pathological response. Rad51 expression affects both chemo- and radiosensitivity in many cancers; however, its role in ESCC is unclear. METHODS Rad51 expression was investigated by immunohistochemical staining with resected specimens in 89 ESCC patients who underwent surgery without preoperative therapy. The association with Rad51 and clinicopathological factors was assessed. The expression of Rad51 was also investigated in pretreatment biopsy specimens in 39 ESCC patients who underwent surgery after NACRT and compared with the pathological response to NACRT. RESULTS Lymph node metastasis was more frequently observed in Rad51-positive cases than negative cases (58.5 vs. 30.6%, P = 0.0168) in patients treated with surgery alone. Disease-specific survival was decreased in Rad51-positive cases compared to Rad51-negative cases (5 year survival: 79.6 vs. 59.3%, P = 0.0324). In NACRT patients, completed pathological responses were more frequently observed in Rad51-negative cases than in Rad51-positive cases (68.8 vs. 46.5%, P = 0.0171). CONCLUSIONS Rad51 expression in ESCC was associated with lymph node metastasis and poor survival. Additionally, Rad51 expression in pretreatment biopsy specimens was a predictive factor for the response to NACRT.

Abstract
OBJECTIVES This study reports an early, single-institution experience of combined thoracoscopic and laparoscopic robotic-assisted minimally invasive esophagectomy (RAMIE) using a four-arm robotic platform, with special attention given to the pitfalls and complications during procedure development. METHODS We conducted a prospective, single-cohort, observational study of patients undergoing RAMIE at a single institution. RESULTS A total of 21 patients (median age, 62 years [range, 37-83 years]) underwent RAMIE with a four-arm robotic platform (17 by Ivor Lewis and 4 by McKeown). Of the patients, 17 (81%) had a complete (R0) resection, and 16 (76%) received induction treatment, the majority (14/21 [67%]) with combined chemoradiation. The median operative time was 556 min (range, 395-807 min), which decreased to 414 min (range, 405-543 min) for the last 5 cases in the series. The median estimated blood loss was 307 cm(3) (range, 200-500 cm(3)), and the median length of hospital stay was 10 days (range, 7-70 days). The median number of lymph nodes resected was 20 (range, 10-49). Five (24%) patients were converted to open procedures. Five patients (24%) had major complications. One (5%) died of complications on postoperative Day 70, and 3 (14%) had clinically significant anastomotic leaks (Grade II or greater, by Common Terminology Criteria for Adverse Events version 3.0). Three patients (14%) in this early experience developed airway fistulas. CONCLUSIONS While four-arm RAMIE may offer advantages over standard minimally invasive esophagectomy approaches, its adoption in a structured program, with critical evaluation of adverse events and subsequent adjustment of technique, is paramount to maximize patient safety, minimize complications and improve the conduct of operation early in the learning curve. Particular technical consideration should be given to prevention of airway complications.

Abstract
Esophageal cancer is a highly lethal and aggressive disease and a major public health problem worldwide. The incidence of esophageal cancer in the western hemisphere has increased by 400 % in the past few decades (Posner et al. 2011). Surgery is the mainstay of definitive management of esophageal cancer; however, the results of surgery alone have been dismal, with survival rates of approximately 15 to 20 % at 5 years (Hingorani et al., Clin Oncol 23:696-705, 2011). The last three decades have seen growing interest in various adjuvant and neoadjuvant treatment strategies, with an aim to improve disease control and overall survival. However, due to conflicting and often contradictory results, there was controversy on the ideal treatment paradigm. Recent evidence suggests an improvement in overall survival with neoadjuvant therapy, both chemotherapy and chemoradiotherapy, over surgery. In this review we address various issues concerning multimodality management of locally advanced esophageal cancers: Does neoadjuvant therapy offer a definite benefit over surgery alone? If so, which neoadjuvant strategy? Does the survival benefit outweigh the increased treatment related toxicity/morbidity? Finally, is neoadjuvant treatment the standard of care for locally advanced resectable esophageal cancer?

Esophageal cancer is an aggressive and physically and emotionally devastating disease. It has one of the poorest survival rates among all malignant tumors, mainly due to late symptom presentation and early metastatic dissemination. Cure is possible through extensive surgery, typically followed by a long recovery period, affecting general well-being, as well as basic aspects of life, such as eating, drinking and socializing. Health-related quality of life (HRQL) is a multidimensional concept assessing symptoms and functions related to a disease or its treatment from the patient's perspective. HRQL is a fundamental part of treatment in surgical oncology, particularly in esophageal cancer. This review assesses the scientific data regarding some HRQL aspects after esophageal cancer surgery, for example, postoperative recovery time, determinants of postoperative HRQL and long-term HRQL.

Tachezy M, Effenberger K, Zander H, Minner S, Gebauer F, Vashist YK, Sauter G, Pantel K, Izbicki JR, Bockhorn M. ALCAM (CD166) expression and serum levels are markers for poor survival of esophageal cancer patients. Int J Cancer 2011; 131:396-405. [PMID: 21858815 DOI: 10.1002/ijc.26377] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2011] [Accepted: 06/29/2011] [Indexed: 12/15/2022]
Abstract
The expression of the activated leukocyte cell adhesion molecule (ALCAM and CD166) is increased in various types of cancer. We aimed to evaluate its role as a prognostic marker for esophageal cancer (EC). We retrospectively analyzed ALCAM expression in 299 primary lesions, 147 lymph node and 46 distant metastases from EC patients, on a tissue microarray using immunohistochemistry. Bone marrow samples from representative cancer patients (n = 16), taken before primary surgery, were stained by double-immunofluorescence for ALCAM and cytokeratins (CK). Blood serum samples from 236 cancer patients and 127 controls were analyzed for serum ALCAM (s-ALCAM) by ELISA. The immunohistochemical analysis showed increased ALCAM expression in the majority of lesions (primary tumor 71%, lymph node 76% and distant metastases 80%). ALCAM expression was not associated with histopathological parameters except for tumor grading (p = 0.015). ALCAM-positive patients had significantly worse recurrence-free and overall survival (OS; p = 0.002). Disseminated tumor cells (DTC) in bone marrow showed two phenotypes, ALCAM+/CK+ (36%) and ALCAM-/CK+ (64%). Multivariate analysis revealed that ALCAM expression and elevated s-ALCAM serum values are powerful prognostic variables for OS in patients with EC (hazard ratio [HR] 3.987, 95% confidence interval [95%CI] 1.906-8.340, p < 0.001 and HR 1.915, 95%CI 1.021-3.592, p = 0.043). The results of our study provide preliminary evidence for the potential clinical utility of ALCAM as a prognostic biomarker for EC, which might be a basis for future clinical application. In addition, ALCAM expression in a subset of DTC of the bone marrow indicates a potential function in the metastatic cascade of EC.

Clin Oncol (R Coll Radiol) 2011; 23:696-705. [PMID: 21684129 DOI: 10.1016/j.clon.2011.05.005] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2011] [Revised: 03/22/2011] [Accepted: 05/18/2011] [Indexed: 02/07/2023]
Abstract
AIMS The optimal neoadjuvant therapy option for locally advanced oesophageal cancer remains elusive. Neoadjuvant chemoradiotherapy (CRT) is the preferred modality of choice in the USA. In contrast, neoadjuvant chemotherapy is commonly used in the UK. We provide a comprehensive overview of the available evidence for defining the ideal neoadjuvant treatment algorithm. MATERIALS AND METHODS The PubMed database combined with American Society of Clinical Oncology and American Society for Therapeutic Radiology and Oncology websites were searched online to identify randomised studies and published meta-analyses that have compared these modalities compared with surgery alone. In particular, we searched for randomised trials that may have directly compared outcomes after neoadjuvant CRT or chemotherapy. RESULTS We identified 17 published randomised studies of neoadjuvant CRT (n = 9) and chemotherapy (n = 8) compared with surgery alone and one prospective series that compared the above modalities against each other. Studies evaluating CRT have reported pathological complete response rates of 15-40% and no increase in postoperative mortality was observed, except in one study that used a hypofractionated radiation schedule. Two randomised studies showed significant survival benefit and the remaining (n = 7) were negative, but showed a trend towards improved survival. Furthermore, at least four meta-analyses have shown improved survival in favour of CRT extending up to an absolute benefit of 13% at 2 years. In comparison, five studies of neoadjuvant chemotherapy showed no survival difference and two of the remaining studies that showed significant benefit included gastric adenocarcinomas and used peri-operative chemotherapy. All the above studies have shown uniformly poor pathological complete response rates of less than 10 percent. Moreover, three meta-analyses were negative, but two showed up to 7% absolute survival benefit at 2 years in favour of chemotherapy. The trial comparing the above modalities showed a trend towards improved survival in favour of CRT, but closed early due to poor recruitment. CONCLUSION Data from the above studies are potentially conflicting and inconclusive for defining the optimal neoadjuvant treatment schedule. In our opinion, the above question can only be answered within the context of a randomised control trial. We have included a proposal for a trial design for direct comparison of these modalities.
