Filter by:The role of preoperative chemotherapy as standard therapy is well-established for advanced esophageal cancer. Immunotherapeutic agents such as Immune checkpoint inhibitors has been shown to improve objective response rate in solid tumors. However, there is a paucity of data regarding the efficacy and safety of preoperative immunotherapy plus chemotherapy in esophageal cancer patients in real-world practice. This study set out to investigate whether the combination of preoperative chemotherapy and immune checkpoint inhibitors is beneficial to improve the objective response rate as well as the pathological complete response rate in a real-world scenario.
Esophageal cancer is the most prevalent cancer globally with poor survival outcome. The prognosis with surgery alone is poor, accounting for 30-40% of overall survival at 5 year. Either neoadjuvant chemotherapy (nCT) or chemoradiotherapy (nCRT) has been shown as efficatious therapy to improve patients outcomes in esophageal or esophagogastric junction cancer as compared with surgery alone. The purpose of this study was to explore the optimal neoadjuvant treatment modalities including PD-1/PD-L1 antibody or targeted drug for patients with esophageal or esophagogastric junction cancer.
Definitive chemoradiotherapy is the standard of care in unresectable esophageal or esophagogastric cancer. A multidisciplinary approach, including chemotherapy and radiotherapy, is important for these patients. Morerover, molecular targeting agents does not show clear efficacy in EC up to now. Nowadays, the pace of development of cancer immunotherapies is accelerating. Clinical evidence of the efficacy of immune checkpoint inhibitors and adoptive immunotherapies herald the onset of a new era in cancer immunotherapy. There have also been recent developments to provide a promising frontier in extending the use of immunotherpay or targeting agents to radiotherapy. The purpose of this study was to explore the optimal treatment modalities including PD-1/PD-L1 antibody or targeted drug for patients with unresectable esophageal or esophagogastric junction cancer.
Chemoradiotherapy（CRT） is the main treatment for esophageal cancer patients with recurrent desease，and checkpoint blockade (PD-1) have been shown to be effective in advanced esophageal cancer. Therefore, PD-1 combined with chemoradiotherapy （CRT）may further improve the efficacy and become a new method for the treatment of esophageal cancer.This study intends to conduct a single-arm, prospective clinical study, aiming to evaluate the safety and efficacy of PD-1 combined with chemoradiotherapy(CRT) in patients with oligometastatic esophageal squamous cell carcinoma.
The purpose of this study is to assess lymph node metastasis rate, distant metastasis rate, disease-specific mortality, and overall mortality in patients with Barrett's related T1b and high risk T1a esophageal adenocarcinoma (EAC) who underwent a diagnostic endoscopic resection.
This is an open-label, parallel group, non-randomized, multicenter phase II study to evaluate the efficacy of spartalizumab (cohorts 1 and 2) and tislelizumab (cohort 3) in monotherapy in patients with PD1-high-expressing tumors.
This is a Phase II, randomized, blinded, active-controlled, global, multicenter study designed to evaluate the safety and efficacy of lomvastomig and tobemstomig, compared with nivolumab, in patients with advanced or metastatic esophageal squamous-cell carcinoma (ESCC) refractory or intolerant to fluoropyrimidine- or taxane- and platinum-based regimen. Following approval of the protocol amendment version 3, recruitment into the lomvastomig arm has been stopped. The decision to stop recruitment for lomvastomig was based on strategic considerations and not based on emerging safety and/or efficacy data. The benefit/risk assessment for lomvastomig remains unchanged. The study was planned to enroll participants randomized in a 1:1:1 ratio to receive lomvastomig, tobemstomig, or nivolumab. With version 3 of the protocol, recruitment into the lomvastomig arm has stopped, and moving forward, participants will be randomized in a 1:1 ratio to receive either tobemstomig or nivolumab.
The study aims to retrospectively investigate the endoscopic resection procedures of cancerous and precancerous lesions of the upper and lower digestive tract in order to evaluate the efficacy and safety outcomes and to compare different resection techniques. In particular, the resection techniques investigated will be mucosectomy, en bloc and piecemeal, endoscopic submucosal dissection (ESD) and its variants, full-thickness resection. The anatomical districts involved will be the esophagus, stomach, duodenum, colon and rectum.
This is a prospective study addressing the challenge of predicting disease progression and/or recurrence in patients diagnosed with metastatic colorectal, pancreatobiliary, or esophagogastric cancer that are receiving anti-cancer therapy.
Neoadjuvant chemoradiotherapy is recommended as standard therapy for resectable esophageal cancer. The recurrence rate after surgery following neoadjuvant chemoradiotherapy is about 35%. Whether achieving pathological complete response after neoadjuvant chemoradiotherapy is significantly associated with recurrence after surgery. It is reported that immunotherapy combined with chemotherapy improved survival compared with chemotherapy alone in first line therapy of advanced esophageal cancer. We hypothesize that the addition of immunotherapy to neoadjuvant chemoradiotherapy is helpful to improving pathologic complete response and survival.
