Filter by:Esophagectomy is an important means of radical treatment of esophageal cancer, but due to local recurrence and metastasis, the 5-year survival rate of patients with esophageal cancer is only 20-30%. Studies have reported that about 50% of patients relapse within 1 year after surgery, and the short-term recurrence rate is high. Therefore, reducing the recurrence rate of esophageal cancer after operation is an important way to improve its prognosis. Porphyromonas gingivalis infection in ESCC tissues was significantly higher than that in paracancer tissues, and was significantly positively correlated with cancer cell differentiation, lymph node metastasis, TNM stage, and shortened survival of ESCC patients. In summary, porphyromonas gingivalis plays an important role in postoperative recurrence of esophageal cancer. Elimination of porphyromonas gingivalis can significantly reduce the recurrence rate of esophageal cancer after operation. Tinidazole is a class of nitroimidazole drugs. It has been pointed out that the pharmacological mechanism of Tinidazole is to inhibit the DNA synthesis of pathogenic bacteria, so as to eliminate bacteria in periodontal tissues and inhibit local inflammation. Based on this, we designed and fabricated a novel oral microneedle patch loaded with tinidazole. Tinidazole oral microneedle patch can effectively remove porphyromonas gingivalis and promote the repair of gingival tissue. In this study, based on the combination of mechanical removal and antibacterial treatment, a combination of ultrasonic dental cleaning and tinidazole oral composite microneedle patch was designed to completely remove porphyromonas gingivalis in oral cavity, and to evaluate the effect of removal of porphyromonas gingivalis in oral cavity on the prognosis of esophageal cancer after radical surgery.
Esophageal squamous cell carcinoma accounts for ~90% of the nearly half-million annual incident cases of esophageal cancer worldwide. The high costs and invasiveness of upper endoscopy constitute a limitation in providing adequate surveillance for at-risk individuals, including those with previous head and neck cancer. The ANGELA study is a prospective evaluation of the minimally-invasive capsule-sponge device, coupled with tissue biomarkers (p53-immunohistochemistry), to detect squamous neoplasia in high-risk individuals.
To evaluate the initial efficacy and safety of paclitaxel for injection (albumin-bound) in combination with apatinib mesylate and adebrelimab in the treatment of locally advanced or metastatic gastric/gastroesophageal junction adenocarcinoma following the progression of previous immunotherapy.
To learn if 18F-FAraG PET scans can find tumors in participants with esophageal cancer and predict a participant's response to treatment.
The objective of this project is to pioneer a novel protocol for the adjunctive screening of early-stage esophageal cancer and its precancerous lesions. The anticipated outcomes include simplifying the training process for users, shortening the duration of examinations, and achieving a more precise assessment of the extent of esophageal cancer invasion than what is currently possible with ultrasound technology. This research endeavors to harness the synergy of endoscopic ultrasound (EUS) and Magnifying endoscopy, augmented by the pattern recognition and correlation capabilities of artificial intelligence (AI), to detect early esophageal squamous cell carcinoma and its invasiveness, along with high-grade intraepithelial neoplasia. The overarching goal is to ascertain the potential and significance of this approach in the early detection of esophageal cancer. The project's primary goals are to develop three distinct AI-assisted diagnostic systems: An AI-driven electronic endoscopic diagnosis system designed to autonomously identify lesions. An AI-based EUS diagnostic system capable of automatically delineating the affected areas. A multimodal diagnostic framework that integrates electronic endoscopy with EUS to enhance diagnostic accuracy and efficiency.
The study examines the diagnostic precision of endosonography, mpMRI and PET/CT in defining tumor boundaries and tumor spread before and after neoadjuvant therapy and definitive surgery.
This study is a prospective, open-label, two-arm exploratory Phase II clinical trial aimed at observing and evaluating the efficacy and safety of combined therapy with cadonilimab and fruquintinib in conjunction with paclitaxel-albumin as second-line treatment for advanced gastric/esophagogastric junction adenocarcinoma. Patients meeting the inclusion criteria were divided into two groups based on whether they had received PD-1/L1 antibody treatment in the first line: Group A (immunotherapy-naive group - patients who had previously failed standard chemotherapy in the first line) and Group B (immunotherapy rechallenge group - patients who had previously failed PD-1/L1 antibody combined chemotherapy in the first line). All patients received combined therapy with cadonilimab and fruquintinib in conjunction with paclitaxel-albumin until intolerable toxic reactions occurred, disease progression, withdrawal of informed consent by the subject, loss to follow-up, death, other conditions judged by the investigator to require termination of treatment, or termination of the study, whichever occurred first. The maximum duration of paclitaxel-albumin treatment was 6 cycles, and cadonilimab treatment did not exceed 1 year. Clinical tumor imaging evaluations were conducted every 8 weeks during treatment using RECIST v1.1 criteria, and safety assessments were performed using CTCAE 5.0, recording adverse events within 30 days from the first dose to the end of treatment.
We intend to conduct a prospective single-arm clinical study to explore the efficacy and safety of immunochemotherapy in neoadjuvant therapy in elderly patients with advanced esophageal squamous cell carcinoma. Most previous randomized controlled studies (such as the 5010 study) have excluded older patients ≥70 years of age. However, in the real world, elderly patients with esophageal cancer account for a large number of patients, and elderly people have many complications and poor tolerance to treatment, which limits the application of synchronous chemoradiotherapy in this group. There is no standard treatment plan for patients over 70 years old, and the purpose of this study is to explore the effectiveness and safety of neoadjuvant immunochemotherapy in the treatment of this group of elderly people.
The investigators conduct this phase II study to evaluate safety and effectiveness of EGCG in patients with dysphagia. Swallowing-related dysphagia and pain scores were recorded using the numerical rating scale (NRS) daily . Barium meal radiography was utilized to measure the luminal size and the length of the lesion area both before and after a week of EGCG treatment. The scales are translated into Chinese and guides in Chinese are developed instructing how to use the scales and perform the assessments.
Radiotherapy plays an important role in multidisciplinary treatment of esophageal cancer. Data from many laboratories indicate that local radiation produces systemic, immune-mediated anti¬tumour and, potentially, antimetastatic effects. Additionally, the combination of local radiotherapy and immune-modulation can augment local tumour control and cause distant (abscopal) antitumour effects through increased tumour-antigen release and antigen-presenting cell (APC) cross-presentation, improved dendritic-cell (DC) function, and enhanced T cell priming. The generation of an effective antitumor immune response requires the presentation of tumor antigens to naïve CD8+ cells in tumor-draining lymph nodes (TDLN) . Tumor-draining lymph nodes, however, are often subject to the immunosuppressive activity of tumor-derived factors, such as cytokines and other bioactive molecules from tumor cells and their associated leukocytes in the primary tumor site that contribute to the overriding of effective rejection mechanisms. Thus, in TDLN a T cell tolerance rather than a T cell activation often occurs, thereby preventing immune attack and facilitating local tumor progression.
