Survival After Induction Chemotherapy and Esophagectomy Is Not Improved by Adjuvant Chemotherapy

Publication date: November 2019Source: The Annals of Thoracic Surgery, Volume 108, Issue 5Author(s): Wanpu Yan, Peiliang Zhao, Hao Fu, Yao Lin, Zhongwu Li, Liang Dai, Yongbo Yang, Xiaozheng Kang, Ke-Neng ChenBackgroundIt remains unclear whether postoperative chemotherapy improves survival among patients with esophageal squamous cell carcinoma who have undergone preoperative chemotherapy and radical resection.MethodsPatients treated between January 2000 and December 2016 were reviewed. Eligible patients were divided into two groups: perioperative chemotherapy (preoperative and postoperative chemotherapy) and neoadjuvant chemotherapy only. The primary endpoint was disease-free survival; the secondary endpoints were overall survival and toxicities attributable to postoperative chemotherapy. To minimize the effect of patient heterogeneity between the two groups, we used propensity score matching. The survival analysis was performed using univariate analysis and a multivariable Cox regression model.ResultsIn total, 252 patients were included in the study. Most were men (208 of 252; 82.5%); median age was 59 years. The follow-up rate was 93.3%. Age, performance status, minimally invasive surgery, and Clavien-Dindo classification were statistically different between the groups (P

Authors: He H, Li PC, Jia W, Hu B, Ji CS Abstract BACKGROUND Recently, targeted therapy for malignant tumors has developed rapidly, but there is still no effective targeted therapy for advanced esophageal squamous cell carcinoma (ESCC). Methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) is a key enzyme involved in folate metabolism and is closely related to the proliferation in many cancers. However, few studies have explored the expression of MTHFD2 in ESCC and its prognostic significance. MATERIAL AND METHODS The expressions of MTHFD2, ki67, and p53 in ESCC tissues were detected by immunohistochemistry. Further, ...

AbstractBackgroundThere has been no definitive evidence of chemoradiotherapy being superior to radiotherapy alone in patients aged 80  years or older. The purpose of the present study was to evaluate the results of radiotherapy and chemoradiotherapy in patients aged 80 years or older with esophageal cancer in the Japanese Nationwide Cancer Database.MethodsA total of 358 patients aged 80  years or older who were treated with radiotherapy alone or with chemoradiotherapy for esophageal cancer between 2009 and 2011 were enrolled.ResultsThe 5-year overall survival (OS) rates in patients with cStages 0 –I, I...

CONCLUSION: Postoperative radiotherapy significantly increased disease-free survival and decreased local regional recurrence rate in patients with pathological T2-3N0M0 thoracic esophageal squamous cell carcinoma with acceptable toxicities in this interim analysis. Further enrollment and follow-up are warranted to validate these findings in this ongoing trial. IMPLICATIONS FOR PRACTICE: The value of adjuvant radiotherapy for patients with node-negative esophageal cancer is not clear. The interim results of this phase III study indicated that postoperative radiotherapy significantly improved disease-free survival and d...

AbstractEsophageal and gastric cancers collectively cause over 1.1 million deaths annually and only 20 –30% of patients respond favorably to current therapies. Cellular therapies using invariant natural killer T (iNKT) cells are showing promise for patients with other cancers; therefore, we investigated if these cells are altered in esophageal and gastric cancer patients. Flow cytometric analysis o f peripheral blood from 139 patients revealed that iNKT cells are depleted from patients with esophageal and gastric adenocarcinoma and esophageal squamous cell carcinoma, both before and after treatment. Interrogation of ...

Abstract BACKGROUND: Oesophageal squamous cell carcinoma is an aggressive disease owing to early and widespread lymph node metastases. Multimodal therapy and radical surgery may improve prognosis. Few studies have investigated the efficacy of radical lymph node and thoracic duct resection. METHODS: Patients with oesophageal squamous cell carcinoma who underwent transthoracic minimally invasive oesophagectomy (TMIE) for cancer at Keio University Hospital between January 2004 and December 2016 were selected. Between 2004 and 2008, TMIE was performed in the lateral decubitus position without thoracic duct resect...

ConclusionsOverexpression of JAB1 promoted the proliferation, migration, and invasion of ESCC cells, and was significantly associated with poor prognosis of ESCC patients. Therefore, JAB1 could be considered as a promising prognostic factor and a possible target for the specific therapy of ESCC.Key pointsIn this study, we found that JAB1 was highly overexpressed in cancer tissues, which could influence the malignant behavior of ESCC cells, and was significantly associated with poor prognosis of ESCC patients.
