Active clinical trials for "Esophageal Neoplasms"

To evaluate the efficacy of endoscopic screening on esophageal cancer (EC) and determine the most cost-effective strategy of endoscopic screening in high risk population in China, 668 villages of Hua county, a high risk area of esophageal cancer, were randomized into screening arm and control arm in a ratio of 1:1 and the total sample size is over 32,000 (~16,000 per group). Participants in the screening arm will accept standard chromoendoscopy examination to detect early esophageal cancer and no screening were designed in the control arm. The incidence of advanced EC, EC-specific mortality and all-cause mortality will be compared within the two groups to test the hypothesis that endoscopic screening would alter the natural history of lesions in esophagus and the incidence of advanced stage EC, EC-specific mortality and all-cause mortality in the screening arm will be lower than the control group. Cost-effectiveness analysis will also be conducted to find the most cost-effective strategy of endoscopic screening in rural China.

This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy.

To assess short and long term outcomes after minimally invasive esophagectomy compared to open esophagectomy. To compare both standard outcome measures as well as patient derived outcome measures, in particular, quality of life (QOL). To look at the applicability of this QOL instrument to this patient group.

Phase Ia: single-dose escalation study: accelerated titration combined with traditional "3+3" dose. Sample size is correlated with the DLT occurring in each dose group. 4 dose groups are expected; the first dose group is the accelerated titration group, which includes only 1 subject; subsequent dose groups are in traditional "3+3" dose increments, with 3-6 subjects in each group; a total of 10-19 subjects are expected in all dose groups. If the DLT is still not present in the highest dose ,the safety monitoring committee(SMC) to determine if it is necessary to continue incrementally to a higher dose.

Esophageal squamous cell carcinoma is a common malignancy in China. Although neoadjuvant chemoradiotherapy followed by esophagectomy remains a standard modality for locally advanced esophageal squamous cell carcinoma, esophagectomy followed by postoperative radiotherapy is also prevalent in China. Several retrospective studies demonstrated that postoperative radiotherapy could improve the prognosis of patients. Nevertheless, there still existed approximately 11.5% and 17.2% of total patients developing local-regional relapse and hematological metastasis. The result of Checkmate 577 has shown that postoperative immunotherapy of nivolumab could improve the disease-free survival (median Disease-free Survival 29.7 mos vs. 11.0 mos). Therefore, investigators aimed to implement a pilot study to explore the safety and efficacy of combining postoperative radiotherapy and immunotherapy for patients with locally advanced esophageal squamous cell carcinoma after esophagectomy.

Disease recurrence and metastasis are common after curative treatment for patients with esophageal cancer. Thus, it is important to identify the risk factors to predict disease recurrence and metastasis. Pleural lavage cytology (PLC) is reported to be associated with disease recurrence and patient survival in lung cancer, but the value is unclear in esophageal cancer. The aim of this study is to evaluate the value of PLC in esophageal cancer patient in terms of frequencies, association with patient survival, and efficacy of postoperative treatment.

To clarify the effect of the number of lymph node dissection and the number of stations on survival

Esophageal cancer, which has a low 5-year overall survival rate (<20%) is increasing in incidence. Previous studies have shown that Hedgehog, AKT, and angiogenic signaling pathways are activated in a significant number of esophageal cancers. Itraconazole, a widely used anti-fungal medication, effectively inhibits these pathways. In this multi-site phase II trial, the investigators will evaluate the effect of itraconazole as a neoadjuvant therapy added to standard of care chemoradiation and surgery in the the treatment of locoregional esophageal and gastroesophageal junction cancers.

The purpose of this experiment is to study the alleviating effects and side effects of different laser irradiation doses on esophageal stricture of esophageal cancer in order to find the appropriate dose of light.

The treatment efficacy for stage IVb esophageal cancer has been improved through chemotherapy combined with immunotherapy recently. On this basis, the investigators intend to conduct a prospective, multicenter phase III clinical trial to assess whether radiotherapy with concurrent chemotherapy and immunotherapy could further improve the survival of patients with metastatic esophageal cancer. Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection (Including Whole Exome Sequencing and proteomics) to explore potential biomarkers for predicting outcomes, efficacy and toxicity.
