Filter by:Esophageal cancer accounts for more than half of the world, seriously affecting people's health in China. 95% patients are squamous cell carcinoma. Surgery is the preferred treatment for early and middle stage esophageal cancer, but patients with clinical stage T4b or other surgical contraindications have no surgical opportunity. In recent years, radical chemoradiotherapy has played a key role in the treatment of local advanced esophageal cancer with some poor predicting biomarkers. Oral bacteria may play a pathogenic role in cancer and other chronic diseases by producing chemical carcinogens and inflammatory factors through direct metabolism. A large number of studies have also suggested that tooth loss and poor oral hygiene are closely related to upper digestive tract cancer, indicating the possible role of oral microorganisms in the occurrence and development of upper digestive tract cancer, and saliva is the main source of oral flora colonization. Therefore, it is worth further research to explore the interaction between microbial metabolism imbalance and radiotherapy in patients with esophageal cancer. In summary, we intend to conduct a prospective cohort study to explore the role of salivary microbes in radiotherapy in patients with initially inoperable patients with local advanced esophageal cancer.
Patients with oligometastatic squamous cell carcinoma were enrolled and randomly assigned to receive either PD-1 inhibitor +/- chemotherapy combined with local therapy or PD-1 inhibitor +/- chemotherapy alone. The primary end point was progression-free survival (PFS). The secondary end points included overall survival, side effects and local control.
This study is a multi-center, non-interventional study. Clinicopathologic, treatment , outcome and efficacy data will be collected from medical records in metastatic esophageal squamous cell carcinoma (ESCC) patients.
The goal of this clinical trial is to evaluate the efficacy and safety of sintilimab as adjuvant therapy in node-positive esophageal squamous cell carcinoma after radical surgery without neoadjuvant therapy. The main question it aims to answer is: • Efficacy of sintilimab as adjuvant therapy Participants will receive sintilimab 200 mg once on day 1, every 21 days(Q3W).
This study is a single-arm early exploratory clinical study. designed to evaluate the safety and tolerability of GT201 in combination with a PD-1 inhibitor for the treatment of advanced head neck squamous carcinoma (HNSCC) subjects with safety and tolerability, as well as pharmacokinetic characterization and efficacy The study consists of two phases. The study consists of two phases, a dose-escalation phase and a dose-expansion phase.
Although definitive chemoradiotherapy (CRT) is the standard treatment option for unresectable locally advanced esophageal cancer, elderly patients tolerate intravenous concurrent CRT less well with age and comorbidities. Previous trials have demonstrated that CRT with oral S-1 was tolerable and provided significant survival benefits over radiotherapy alone in elderly patients with esophageal squamous cell carcinoma (ESCC). However, as high as 54% of patients with elderly ESCC experienced locoregional or distant recurrence after CRT. Therefore, a more effective regimen for older patients is needed. Immune checkpoint inhibitors targeting PD-1/PD-L1 have shown substantial clinical benefits in advanced esophageal cancer. Recently, the combination of immunotherapy with CRT has emerged as a promising strategy to improve clinical outcomes in locally advanced esophageal cancer. The aim of this study was to evaluate the efficacy and safety of toripalimab (an anti-PD-1 antibody) after concurrent CRT in elderly patients with locally advanced ESCC.
Patients with liver metastasis from esophagus squamous (ESC) are usually offered systemic therapy. However, for those with predominant liver disease or failure of system therapy, local liver management becomes an option. This prospective single center study aimed to evaluate the efficacy and adverse events of hepatic arterial infusion chemotherapy (HAIC) using percutaneous catheter placement techniques for liver metastases from esophagus squamous (ESC).
A total of at least 1,000 participants with suspicion of cancer including at least 107 subjects who will be diagnosed with OSCC or OPSCC will be enrolled from either primary or secondary care centers in the U.S. Clinicians will use Viome collection kits to collect saliva samples from eligible patients.
SCR-ESCC-02 is a multicenter, phase I/II clinical study to investigate the safety and efficacy of induction immunochemotherapy followed by concurrent chemoradiotherapy with anti-PD-1 therapy in patients diagnosed with locally advanced, unresectable esophageal cancer.
This trial aims to evaluate whether the addition of anti-PD-1 antibody to adjuvant postoperative chemoradiotherapy could improve disease free survival in patients with high-risk locally advanced head and neck squamous cell carcinoma (HNSCC).
