Active clinical trials for "Esophageal Squamous Cell Carcinoma"

This purpose of this observational study is to review medical chart and patient survey data collection within an early access to medicines scheme (EAMS) program. Participant who are eligible, provide consent and enroll into the squamous cell oesophageal cancer EAMS to receive Nivolumab will be included in this study.

Narrow-Band Imaging (NBI) is as sensitive as Lugol chromoendoscopy to detect oesophageal squamous cell carcinoma (SCC) and appears more specific than Lugol chromoendoscopy in expert centres but its specificity in current practice is not known. This study aimed to prove the superiority of NBI specificity over Lugol chromoendoscopy to detect oesophageal SCC and high-grade dysplasia (HGD) in current practice (including tertiary care centres, local hospitals and private clinics).

To clarify the effect of Two-field or Three-field Lymphadenectomy on the survival of esophageal squamous cell carcinoma.

Evidence from laboratory studies suggests that aspirin and tea polyphenols may have an antineoplastic effect in esophageal squamous cell carcinoma (ESCC). To assess the safety and efficacy of aspirin and tea polyphenols for preventing ESCC, the investigators designed this double-blind, randomized controlled clinical trial. Research project is planned to recruit 10,000 participants with the ages of 40-60 years in Fengfeng city, Hebei province, China, which has been known as a high incidence region of ESCC. All the participants receive endoscopic examination. Lugol's chromoendoscopy is used to identify esophageal unstained lesions (USLs). The location and size of each USL will be recorded followed by collecting biopsy samples from each USL. Participants with USL are randomly assigned to receive 100 mg/d of aspirin (n=200), 100 mg/d of tea polyphenols (n=200), or placebo (n=200) for six months. Follow-up consists of 2 endoscopic surveillance cycles (the first interval will be at six months and the second at 3 or 5 years later). The primary outcome measure was occurrence of high grade dysplasia and invasive ESCC. Secondary outcome was the mortality of the participants and adverse events.

Background: Esophageal cancer is a common cause of cancer deaths. Most cases of this cancer are esophageal squamous cell carcinoma (ESCC). Many of these cases come from two parts of the world with high-risk. One of these is in East Africa and include the country of Malawi. Researchers want to learn what factors explain the high risk there so we can understand better what causes this cancer in people everywhere. Objective: To learn more about causes and outcomes of esophageal squamous cell carcinoma using Malawi because of the large number of cases in that country. Eligibility: Adults at least 18 years old who have ESCC and live in a certain region of Malawi Adults in the same age group and location who do not have ESCC Design: Participants will be screened at a hospital in Malawi. Participants will have a 1-hour interview. They will answer questions about: Demographics (age, ethnicity, education) Place of residence Medical history and family medical history Drug, alcohol, and tobacco use Hot beverage consumption Indoor air pollution Occupation Food habits Farming Gastrointestinal health Participants will have their teeth and fingernails examined. Participants will be asked to give samples of blood, urine, saliva, toenails, and for the cancer cases, a small piece of their tumor. Participants will have 4 phone calls a year for 2 years to ask about their health....

the investigators randomly divide the eligible objects into two groups:1. objects in this group will first receive OE endoscopy observation and subsequent white light imaging(WLI) observation during oropharynx and hypopharynx; 2. objects in this group will first receive WLI observation and subsequent OE observation during oropharynx and hypopharynx. Then, the investigators will compare the detect rate of oropharyngeal and hypopharyngeal superficial squamous cell carcinoma of two groups to find if OE endoscopy can improve the detect rate of oropharyngeal and hypopharyngeal superficial squamous cell carcinoma in esophageal cancer patients.

Esophageal squamous cell carcinoma is one of the most common malignant tumor of upper digestive tract. However, the detection rate and diagnosis accuracy of early esophageal squamous cell cancer is low. The aim of this study is to develop a computer-assisted diagnosis tool combining with optical magnifying endoscopy for early detection and accurate diagnosis of it.

Background: Esophageal cancer is the sixth leading cause of cancer deaths worldwide. Two primary cell types, squamous cell carcinoma and adenocarcinoma, account for most cases. Of the two, esophageal squamous cell carcinoma (ESCC) accounts for more than 80 percent of all deaths from esophageal cancer. Many cases occur in certain areas with defined geographic boundaries, including parts of Kenya. Studies of ESCC in developed countries (such as the United States) suggest that heavy tobacco and alcohol use, poor diet, and low socioeconomic status are the primary risk factors. Males and African Americans are also at higher risk. However, these risk factors do not fully explain the prevalence of cases in several of the identified geographic areas. ESCC is the most common cancer seen at Tenwek Hospital in western Kenya, and a notable number of patients are 30 years of age or younger. Objectives: To test the feasibility of a new protocol by recruiting visitors to Tenwek Hospital and volunteers from the general population for study purposes. To use the new protocol to obtain blood and urine samples from ESCC cases in Tenwek Hospital and from nonpatient volunteers. Eligibility: Hospital patients and volunteers who live within 50 kilometers of Tenwek Hospital in western Kenya. Design: All participants will complete a questionnaire and provide blood and urine samples for testing. The questionnaire will include questions about individual and family medical history, living conditions, lifestyle, habits, and diet. Blood and urine samples will be collected from all participants after the questionnaire. Biological samples will be shipped to the United States for further testing. Treatment will not be offered as part of this study.

A single-institution, randomize controlled trial is to be held to evaluate the correlation between blood supply in the gastic conduit and the incidence of anastomotic fistula during radical operation for esophageal squamous cell carcinoma by fluorescence angiography.

The investigators aim to evaluate the performance of Narrow Band Imaging (NBI) endoscopy in Esophageal Squamous Cell Carcinoma (ESCC) screening, as compared to the currently used White Light Endoscopy (WLE) and Lugol's Iodine Staining Endoscopy (ISE). NBI is a simple, safe and non-invasive technique, which can provide real-time optical staining for suspicious lesions. This trial is designated to enroll 10000 participants from five centers located in different regions (North, West and South) in China, which would provide real-world evidence for the recommendation of endoscopic diagnostic technique used in ESCC screening projects.
