Digestive System Neoplasms

The purpose of this study is to learn more about a new medicine called PF-08634404, and how well it works in people with cancer of the colon or rectum (CRC)). The goal is to understand if the new study medicine, combined with chemotherapy that is approved for colorectal cancer, can help people whose cancer has spread or returned after treatments taken before. To join the study, participants must meet the following conditions: * Be 18 years or older. * Have colorectal cancer that has spread to other parts of your body. * Be in good enough health to receive study treatment. * Should not be pregnant before starting treatment. Participants will be randomized (like flipping a coin) to one of 2 different treatment arms. The first arm (Arm A) will include the new medicine PF-08634404 in combination with chemotherapy that is approved for colorectal cancer, and the second arm (Arm B) will include an approved medicine for colorectal cancer, called Bevacizumab, in combination with chemotherapy that is approved for this type of cancer. Participants and their doctors will not know which arm they are being assigned to. Participants will receive all the study medications through intravenous (IV) infusions, which means the medicine is given directly into a vein. The treatment will be given in cycles, and participants may continue receiving it if it is helping and they are not experiencing serious side effects. The medicine will be given at a clinical site, where trained medical staff will check participants during and after each treatment. * The study is expected to last approximately 33 months for each participant. * Participants will have regular visits to the study site for treatment, health checks, and tests. * After stopping treatment, participants will return for a final visit about 30 to37 days later to check their health and review any side effects. * Follow-up will continue every 12 weeks by phone or in person or by reviewing health records to check on health status and any new treatments.

The primary purpose of this study is to determine the non-inferiority of overall survival FOLFIRI with or without Bevacizumab compared with Irinotecan (CPT-11) with or without Bevacizumab as Second-line therapy in Patient with Metastatic Colorectal Cancer.

This study is a prospective, single-arm, single-center trial evaluating the efficacy of TACE combined with multimodal ablation, Tislelizumab, and lenvatinib in the treatment of unresectable primary liver cancer.

Radiofrequency ablation has been used for treatment of solid neoplasms of the liver, lung, kidney and adrenal. Recently, EUS-guided RFA has become available and the device allows EUS-guided treatment of solid abdominal neoplasms. The procedure has been shown to be feasible in the porcine pancreas and was used to treat small groups of patients that are not suitable for surgery suffering from pancreatic cancers. The aim of the current study is to perform a multi-center prospective study on EUS-guided radiofrequency ablation (RFA) of solid abdominal neoplasms. The hypothesis is that EUS-guided RFA is safe, feasible and effective for treating solid abdominal neoplasms.

Sarcopenia is a complex syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength. In patients with cancer, sarcopenia is associated with poorer prognosis, increased treatment-related toxicity, higher postoperative complication rates, reduced response to therapy, and decreased quality of life. Importantly, sarcopenia may be present even in patients with preserved nutritional status or overweight. Patients with gastrointestinal cancers are at particularly high risk of developing sarcopenia, both as a consequence of the malignant disease itself and as a result of systemic anticancer treatment. Early identification of patients at risk is therefore essential in order to enable timely nutritional and supportive interventions. The aim of this study is to evaluate the proportion of patients with gastrointestinal cancer who screen positive for sarcopenia risk using the SARC-F questionnaire before the start of systemic treatment and during treatment. Patients with a positive screening result will be referred for further clinical nutritional assessment and managed according to a multidisciplinary approach.

This study is a prospective, non-randomized, dual-cohort Phase II clinical trial designed to explore the efficacy and safety of radiotherapy combined with intraperitoneal injection of Recombinant Mutant Human Tumor Necrosis Factor (rmhTNF-NC) and tislelizumab in the treatment of malignant ascites that has failed prior standard therapy. After completing the informed consent process, eligible patients who meet the inclusion criteria will be enrolled. Participants will receive palliative radiotherapy combined with intraperitoneal perfusion of rmhTNF-NC and tislelizumab according to the study protocol. Before and after one cycle of treatment, abdominal ultrasound will be used to evaluate the response rate of ascites. Safety assessments will be conducted using NCI-CTCAE v5.0.

This is a prospective single-arm exploratory clinical study. The efficacy and safety of camrelizumab combined with chemoradiotherapy and camrelizumab combined with chemotherapy were evaluated in patients with advanced esophageal cancer who had not previously received any systemic antitumor therapy for esophageal cancer.

The purpose of this study is to assess the safety, feasibility, and efficacy of personalized mRNA vaccine iNeo-Vac-R01 with standard adjuvant therapy in subjects with surgically resected digestive system neoplasms.

The purpose of this study is to assess the safety, feasibility, and efficacy of personalized mRNA vaccine iNeo-Vac-R01 in combination with first-line treatment in subjects with advanced digestive system neoplasms.

The purpose of this study is to assess the safety, feasibility, and efficacy of personalized mRNA vaccine iNeo-Vac-R01 alone in subjects with advanced digestive system neoplasms.

This study aims to pool the clinical experience of Spanish centers treating patients with 177Lu-DOTATATE to evaluate the efficacy, tolerance, and safety of the drug in routine clinical practice and to learn about the profiles of patients and tumors treated and the results in each type of patient and tumor.

This is an Open, Single Arm, Exploratory and Phase II Clinical Trial of Anlotinib Hydrochloride Capsules Combined With TQB2450 Injection in Esophageal Squamous Cell Carcinoma (ESCC) Patients as Postoperative Adjuvant Therapy. In order to observe and evaluate the efficacy and safety of Anlotinib Hydrochloride Capsules combined with TQB2450 Injection in treatment of patients with ESCC. The primary endpoint is disease free survival (DFS).
