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.
Oesophageal Squamous Cell Carcinoma (OSCC) is a cancer of the food pipe that affects around 2000 patients in the UK every year. It is often detected at an advanced stage, resulting in poor survival (5-year survival less than 20%). Early detection can improve survival (5-year survival >70%). Therefore, early detection is vital to improving survival. There are no national screening guidelines, and an endoscopy (A camera test to look at the food pipe) is the only available test to detect OSCC. Early detection of OSCC is challenging for many reasons. Firstly, early disease symptoms are non-specific, which patients often overlook. Secondly, 'Alarm' symptoms such as weight loss, difficulty swallowing or vomiting blood are signs of advanced stage. Lastly, endoscopy is an invasive test with associated risks and significant discomfort. The investigators propose to develop a breath test for patients with non-specific symptoms. Breath testing has the ideal characteristics for a triage test because it is non-invasive, simple to perform, cost-effective and highly acceptable to patients. The test is based on identifying volatile organic compounds (VOCs, small molecules) that are produced by the cancer and released in breath. The breath test will be offered by General Practitioners (GPs) to patients with non-specific symptoms. Those who test positive will be referred for an urgent camera test, and those who test negative can be reassured.
This project intends to study the efficacy and safety of camrelizumab combined with chemotherapy followed by radiotherapy in the perioperative treatment of AEG.
This is an open-label, single-arm, single-center clinical study to investigate the safety and efficacy of fuquinitinib combined with PD-1 inhibitors and first-line chemotherapy in the treatment of inoperable HER2-negative advanced GC/GEJC. Eligible enrolled patients received 6 cycles of combined treatment with fuquinitinib combined with PD-1 inhibitor and chemotherapy (XELOX/SOX) regimen. Maintenance treatment was fuquinitinib combined with PD-1 inhibitor and Teghio/capecitabine until disease progression or toxicity became intolerable. The longest duration of PD-1 inhibitor treatment is 24 months.
The purpose of this study is to evaluate the efficacy and safety of perioperative Disitamab Vedotin plus Toripalimab and XELOX versus Disitamab Vedotin plus Toripalimab versus XELOX in subjects with HER2-expressing resectable locally advanced gastric or gastroesophageal junction adenocarcinoma.
Definitive chemoradiotherapy (CRT) is the standard treatment option for unresectable locally advanced esophageal cancer. However, as high as more than 40% of patients with esophageal cancer experienced locoregional recurrence after definitive CRT. Immune checkpoint inhibitors targeting PD-1/PD-L1 and/or CTLA-4 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 esophageal cancer. The aim of this study was to evaluate the efficacy and safety of cadonilimab (a bispecific PD-1/CTLA-4 antibody) combined with induction chemotherapy followed by definitive radiotherapy in patients with locally advanced esophageal squamous cell carcinoma.
Esophageal cancer continues to be one of the most challenging topics and the subjects of numerous studies. Surgery is the mainstay for curative treatment and the need to improve all aspects of perioperative management in order to reduce morbidity and mortality, continues to be of immense importance. Cited as the sixth most common cause of cancer-related death worldwide, esophageal cancer has a distinct geographic distribution known as the esophageal cancer belt: north central China through the central Asian republics to northern Iran, and from eastern to southern Africa. Squamous-cell carcinoma and adenocarcinoma are the two main histological subtypes of esophageal cancer, in a geographic differentiation as well, with squamous-cell carcinoma as the most common esophageal cancer subtype worldwide. Though adenocarcinoma is at a considerable rise in Western populations and has become the predominant subtype North America, Australia and Europe. Although an ongoing improvement has been marked in the long-term survival after esophagectomy, it is still a highly invasive procedure with serious post-operative complications and entails a high morbidity and mortality rates. Rates of mortality and morbidity range vastly in the literature with 30-day mortality reaching 11-22%. Complication rates up to 50%, with anastomotic leaks as the main complication ranging widely 0-35%. Various risk factors have been proposed as contributors to mortality and morbidity in general and to anastomotic leaks in particular. These include both patient and tumoral characteristics such as premedical history and perioperative factors as tumor location, surgical technique and perioperative treatment. The microbiome as a contributor to a patients' disease progression and management is of great interest in the understanding and better management of cancer patients as a whole and of the gastrointestinal tract in specific. The contribution of the microbiome of a patient to colorectal cancer progression and to anastomotic leaks in the post-operative period has been addressed vastly in the literature in recent years, showing a distinct correlation to specific microbiota profile. Shogan et al. depicted a potential molecular mechanism of bacterial-driven anastomotic leak. It was shown that strains of the commensal organism Enterococcus faecalis could cause anastomotic leakage by causing direct collagen degradation at the site of a freshly constructed anastomosis, and indirectly by bacterial-induced over activation of host matrix metalloproteinase 9 (MMP9). A geographic differentiation in microbiota of Colorectal Cancer (CRC) was also shown by comparing tumor tissue and adjacent tissue of Colorectal Cancer patients from the US and Spain, elaborating yet another aspect of the importance of microbiome of cancer patients. Oropharyngeal microbiome profiling has been proven as a possible predictor for post esophagectomy pneumonia projecting on overall survival as well. A recent study by Rishindra et al from the university of Michigan shows a strong correlation of post esophagectomy anastomotic leaks and increased bacterial variance in preoperative oral and gastric flora. We hypothesize that a correlation exists between microbiome of esophageal cancer patients and post esophagectomy anastomotic leaks. According to former evidence microbiota are integrated into the tumor and therefore the microbial profile of the host (patient) may be represented by tumor microbiota. In this proposed study, we intend to characterize retrospectively the microbial signature of esophageal tumors and to study whether there is a correlation between differential microbial signature and risk of post esophagectomy anastomotic leaks.
This study is a open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CART cell preparations, and to reliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CART cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.
This study will assess the efficacy and safety of SHR-A1811 compared with treatment chosen by the investigator in participants with HER2-positive (defined as immunohistochemistry [IHC] 3+ or IHC 2+/in situ hybridization [ISH]+) gastric or GEJ adenocarcinoma (based on [American Society of Clinical Oncology (ASCO) College of American Pathologists (CAP) guidelines who have progressed on or after a first-line anti-HER2 therapy-containing regimen.
