Abstract   There is limited evidence for effectiveness of adjuvant chemotherapy in esophageal squamous cell carcinoma. We conducted a multi-center randomized controlled trial to assess whether adjuvant Capecitabine and Cisplatin improve survival compared with surgery only among patients with resectable esophageal squamous cell carcinoma. Methods This is a multicenter randomized controlled trials conducted at five hospitals in Korea from Mar 2005 to Dec 2018. Patients were eligible if they underwent curative resection for esophageal squamous cell carcinoma and diagnosed with pathologic T2–3 or N1 stage, according to 6th edition of TNM cancer staging system. Patients who were diagnosed with cervical esophageal cancer, had previous history of cancer, or received neoadjuvant therapy were excluded. Intervention group received 4 cycles of adjuvant chemotherapy (Capecitabine 1,000 mg/m2 b.i.d for 14 days and intravenous Cisplatin 75 mg/m2 at Day1, every 3 weeks). The primary endpoint was disease free survival. Results 136 patients were randomly assigned to adjuvant chemotherapy group (n = 68) or surgery alone group (n = 68). Seven patients who rejected chemotherapy after randomization were excluded from the final analysis. The cumulative incidence of recurrence within 18 months after surgery was significantly lower in the adjuvant chemotherapy group compared to the surgery alone group (Hazard Ratio (HR), 0.45; 95% Confidence Interval (CI), 0.22–0.91). After long-term follow-up (median 3.3 years, maximum 14 years), disease free survival and overall survival were not different between two groups. (HR, 0.77; 95% CI, 0.49–1.18 and HR, 0.85; 95% CI, 0.55–1.34, respectively.) Conclusion Adjuvant chemotherapy after curative resection in patients with esophageal squamous cell carcinoma reduced early recurrence but this does not extend to long-term disease free and overall survival due to limited sample size. Additional randomized controlled trials with larger sample would be necessary to confirm the effectiveness of adjuvant chemotherapy in esophageal squamous cell carcinoma.

Abstract There is limited evidence for the effectiveness of adjuvant chemotherapy in esophageal squamous cell carcinoma (ESCC). This study aimed to assess whether adjuvant capecitabine and cisplatin improve survival compared to surgery alone among patients with locally advanced ESCC. This is a multicenter randomized controlled trial. Patients were eligible if they underwent curative resection for ESCC staged T2–4 or N1 and M0 according to the TNM cancer staging system sixth edition. The intervention group received four cycles of adjuvant chemotherapy (capecitabine: 1,000 mg/m 2 b.i.d for 14 days, and intravenous cisplatin: 75 mg/m2 at day 1, every 3 weeks). A total of 136 patients were randomly assigned to either the adjuvant chemotherapy group (n = 68) or surgery-alone group (n = 68). Seven patients who rejected chemotherapy after randomization were excluded from the final analysis. The cumulative incidence of recurrence within 18 months after surgery was significantly lower in the adjuvant chemotherapy group than in the surgery-alone group (hazard ratio [HR]: 0.49; 95% confidence interval (CI): 0.25–0.95]. However, the 5- and 10-year disease-free survival did not differ between treatment groups (HR: 0.84; 95% CI: 0.53–1.34 and HR: 0.76; 95% CI: 0.50–1.18, respectively). Adjuvant chemotherapy after curative resection in patients with locally advanced ESCC reduced early recurrence but had no statistically significant increase in the long-term disease-free survival. Due to the limited sample size of this study, additional randomized controlled trials with larger sample sizes are necessary.

Abstract OBJECTIVES Our goal was to compare short- and long-term outcomes between 3-field lymphadenectomy (3-FL) and modern 2-field lymphadenectomy (2-FL) in patients with thoracic oesophageal squamous cell carcinoma. METHODS We reviewed clinical outcomes for 298 patients with thoracic oesophageal squamous cell carcinoma who underwent 3-FL or modern 2-FL from March 2008 to December 2013 at a major cancer hospital in Guangzhou, southern China. Propensity score matching was used to balance baseline differences, and 83 pairs of cases were selected. Postoperative complications, recurrence patterns and survival outcomes were compared between the 2 groups. RESULTS Compared with modern 2-FL, 3-FL led to higher overall operative morbidity rates [78.3% vs 61.4%, odds ratio (OR) 2.266, 95% confidence interval (CI) 1.143–4.490; P = 0.019], with higher recurrent nerve palsy rates (47.0% vs 19.3%, OR 3.712, 95% CI 1.852–7.438; P < 0.0001), more respiratory failures (18.1% vs 6.0%, OR 3.441, 95% CI 1.189–9.963; P = 0.023) and longer postoperative hospital stays (23 vs 17 days, P = 0.002). The 5-year overall survival rate (58.5% vs 59.4%; P = 0.960) and the 5-year disease-free survival rate 50.1% vs 54.5%; P = 0.482) were comparable between the 2 groups. Multivariable analysis showed that additional cervical lymph node dissection was not associated with overall survival [hazard ratio (HR) 1.039, 95% CI 0.637–1.696; P = 0.878] and disease-free survival (HR 0.868, 95% CI 0.548–1.376; P = 0.547). The overall recurrence rate and cervical nodal recurrence rate were not significantly different between the 2 groups. CONCLUSIONS Additional cervical lymphadenectomy did not lead to added survival benefit when compared with modern 2-FL in patients with thoracic oesophageal squamous cell carcinoma. Recurrence was similar in patients undergoing 3-FL and modern 2-FL. 3-FL resulted in more postoperative complications.

Objective: For patients with esophageal squamous cell carcinoma, preoperative chemoradiotherapy followed by planned esophagectomy is used as a curative treatment modality. However, the impact of radiotherapy dose remains undefined. Method: A total of 141 patients with stage III esophageal squamous cell carcinoma (ESCC; as defined by the 7th American Joint Committee on Cancer), receiving preoperative chemoradiotherapy followed by esophagectomy between 2000 and 2015 at Kaohsiung Chang Gung Memorial Hospital, Taiwan, were retrospectively reviewed. The radiotherapy dose of preoperative chemoradiotherapy (36 Gy before 2009 and 50–50.4 Gy after 2009) and other clinicopathological parameters were collected and correlated with the response to chemoradiotherapy and treatment outcome. Result: Of these 141 patients, the radiotherapy dose was 36 Gy in 59 (42%) patients and 50 Gy in 82 (58%) patients. A complete pathological response was noted in 12 (20%) of 59 patients receiving 36 Gy radiotherapy, and 37 (45%) of 82 patients receiving 50 Gy radiotherapy (p = 0.002). The three-year overall survival and disease-free survival rates were 31% and 25% in patients receiving 36 Gy radiotherapy, and 54% and 46% in patients receiving 50–50.4 Gy radiotherapy, respectively (p = 0.023 for overall survival; p = 0.047 for disease-free survival). Multivariate analysis showed that a higher radiotherapy dose was associated with increased pathological complete response (p = 0.003, hazard ratio: 3.215), better overall survival (p = 0.024, hazard ratio: 1.585), and superior disease-free survival (p = 0.049, hazard ratio: 1.493). However, higher radiotherapy doses revealed more surgical complications, including acute respiratory distress syndrome (p = 0.048) and anastomosis leaks (p = 0.004). Conclusion: For patients with locally advanced ESCC, preoperative chemoradiotherapy with higher radiotherapy doses led to increased pathologic complete response rates and improved survival.

Purpose: We performed a multicenter randomized controlled trial to determine whether postoperative adjuvant chemotherapy improves outcome in patients with esophageal squamous cell carcinoma undergoing radical surgery. Patients and Methods: Patients undergoing transthoracic esophagectomy with lymphadenectomy between July 1992 and January 1997 at 17 institutions were randomly assigned to receive surgery alone or surgery plus chemotherapy including two courses of cisplatin (80 mg/m2 of body-surface area × 1 day) and fluorouracil (800 mg/m2 × 5 days) within 2 months after surgery. Adaptive stratification factors were institution and lymph node status (pN0 versus pN1). The primary end point was disease-free survival. Results: Of the 242 patients, 122 were assigned to surgery alone, and 120 to surgery plus chemotherapy. In the surgery plus chemotherapy group, 91 patients (75%) received both full courses of chemotherapy; grade 3 or 4 hematologic or nonhematologic toxicities were limited. The 5-year disease-free survival rate was 45% with surgery alone, and 55% with surgery plus chemotherapy (one-sided log-rank, P = .037). The 5-year overall survival rate was 52% and 61%, respectively (P = .13). Risk reduction by postoperative chemotherapy was remarkable in the subgroup with lymph node metastasis. Conclusion: Postoperative adjuvant chemotherapy with cisplatin and fluorouracil is better able to prevent relapse in patients with esophageal cancer than surgery alone.

Abstract Background Esophageal squamous cell carcinoma (ESCC) has become one of the most serious diseases affecting populations worldwide and is the primary subtype of esophageal cancer (EC). However, the molecular mechanisms governing the development of ESCC have not been fully elucidated. Methods The robust rank aggregation method was performed to identify the differentially expressed genes (DEGs) in six datasets (GSE17351, GSE20347, GSE23400, GSE26886, GSE38129 and GSE77861) from the Gene Expression Omnibus (GEO). The Search Tool for the Retrieval of Interacting Genes (STRING) database was utilized to extract four hub genes from the protein–protein interaction (PPI) network. Module analysis and disease free survival analysis of the four hub genes were performed by Cytoscape and GEPIA. The expression of hub genes was analyzed by GEPIA and the Oncomine database and verified by real-time quantitative PCR (qRT-PCR). Results In total, 720 DEGs were identified in the present study; these genes consisted of 302 upregulated genes and 418 downregulated genes that were significantly enriched in the cellular component of the extracellular matrix part followed by the biological process of the cell cycle phase and nuclear division. The primary enriched pathways were hsa04110:Cell cycle and hsa03030:DNA replication. Four hub genes were screened out, namely, SPP1, MMP12, COL10A1 and COL5A2. These hub genes all exhibited notably increased expression in ESCC samples compared with normal samples, and ESCC patients with upregulation of all four hub genes exhibited worse disease free survival. Conclusions SPP1, MMP12, COL10A1 and COL5A2 may participate in the tumorigenesis of ESCC and demonstrate the potential to serve as molecular biomarkers in the early diagnosis of ESCC. This study may help to elucidate the molecular mechanisms governing ESCC and facilitate the selection of targets for early treatment and diagnosis.

In the present study, we aimed to investigate the clinical and prognostic values of CDK4 amplification and improve the risk stratification in patients with esophageal squamous cell carcinoma. CDK4 amplification was analyzed by fluorescence in situ hybridization using tissue microarray consisting of representative tissues of 520 patients with esophageal squamous cell carcinoma, and its correlation with clinicopathological features and clinical outcomes were evaluated. CDK4 amplification was found in 8.5% (44/520) of patients with esophageal squamous cell carcinoma. CDK4 amplification was negatively correlated with disease progression (P = 0.003) and death (P = 0.006). Patients with CDK4 amplification showed a significantly better disease-free survival (P = 0.016) and overall survival (P = 0.023) compared with those patients without CDK4 amplification. When patients were further stratified into I–II stage groups and III–IV stage groups, CDK4 amplification was significantly associated with both better disease-free survival (P = 0.023) and overall survival (P = 0.025) in the I–II stage group rather than the III–IV stage group. On univariate and multivariate analysis, invasive depth and CDK4 amplification were associated with disease-free survival and overall survival. Taken together, CDK4 amplification was identified as an independent prognostic factor for survival, which could be incorporated into the tumor–node–metastasis staging system to refine risk stratification of patients with esophageal squamous cell carcinoma.

33 Background: Elevated neutrophil to lymphocyte ratio (NLR) reflects patients’ inflammation status and closely relates to tumor progression. The aim of this study was to evaluate the clinical significance of the preoperative NLR in patients who undergo an esophagectomy for esophageal squamous cell carcinoma. Methods: A total of 340 patients who underwent an esophagectomy for esophageal squamous cell carcinoma between 2003 and 2008 were retrospectively reviewed. The NLR ≥ 3 was considered to be elevated and the patients were divided into two groups. The overall and disease-free survival curves of the two NLR groups were determined using the Kaplan-Meier method and were compared using a log-rank test. A cox proportional hazards regression analysis was used for the univariate and multivariate analyses. Results: The study included 306 males and 34 females. Seventy-two patients (21%) had an elevated NLR. The 5-year overall survival for patients with high NLR was significantly worse than that for patients with normal NLR (41% vs 69%, p < 0.001). The 5-year disease-free survival for patients with high NLR was significantly worse than that for patients with normal NLR (41% vs 59%, p < 0.001). In multivariate analysis, a high NLR (HR 1.76, 95% CI 1.19-2.60, p = 0.005), an upper tumor location (HR 1.97, 95% CI 1.18-3.30, p = 0.010), an advanced T stage (HR 2.71, 95% CI 1.70-4.31, p < 0.001), and a larger number of metastatic lymph nodes (HR 4.38, 95% CI 1.18-3.30, p < 0.001) were independent predictors of poor overall survival. Conclusions: Our results suggested that the elevated preoperative NLR predicts poor overall and disease-free survival after an esophagectomy for esophageal squamous cell carcinoma.
