Active clinical trials for "Gastrointestinal Neoplasms"

Current curative treatment of digestive peritoneal carcinomatosis consists of complete cytoreduction surgery associated with intraperitoneal chemotherapy. This treatment has important limits: a high morbimortality and the impossibility of repeating the sessions. The majority of patients are therefore treated with systemic chemotherapy, which despite its progress, remains palliative. Pressurized Intraperitoneal aerosol chemotherapy (PIPAC) has many advantages: under laparoscopy, low morbidity, good intratumoral penetration of cytotoxics, possibility of repeating the sessions and low financial cost. Therefore, the investigator propose a phase 1 study, in colorectal and stomach cancer, with oxaliplatin doses escalation in Pressurized Intraperitoneal aerosol chemotherapy. It would allow a better tumor response, with potentially few risks and thus improve survival in patients with digestive peritoneal carcinoses, increasing access to cytoreductive surgery.

The purpose of this study is to compare the similarities and differences of 99mTc-FAPI quantitative SPECT/CT and 68Ga-FAPI PET/CT in the diagnosis and staging of gastrointestinal tumors, and clinical diagnosis and economic value of 99mTc-FAPI quantitative SPECT/CT for the gastrointestinal tumors.

Incidence of digestive cancers increase and half of new cases will be people of 75 years or more in 2050. Surgery is one of the main treatment's strategy but post-operative morbi-mortality increases with age. Pre-operative Geriatric Assessment enable to identify frail or vulnerable patients at risk of post-operative complications. The coordinating team postulate that a geriatric and surgical co-management with a combination of several targeted geriatric interventions with usual post-operative care could improve the post-operative care and decrease the risk of morbi-mortality in older patients with digestive cancers.

Background: Many advances have been made in cancer treatments, but more research is needed. Comparing samples of cancerous tissue to samples of normal, noncancerous tissues may help find differences between them. These differences may help researchers find new ways to treat cancer. Objective: To collect tissues and blood samples from people with known or suspected cancer. The samples will be used to help identify new targets for cancer treatments. Eligibility: People aged 18 years and older with a known or suspected cancer that requires surgery or biopsy. Design: Participants will be screened. They will answer questions about their health. They can do this on the phone or in person. Researchers will collect information from participants medical records. Data may include information about any prior or current cancers. Data about other medical conditions may also be collected. Participants will have blood drawn. Some of the blood will be tested for HIV and hepatitis B and C. Some of the blood will be used for genetic research. Participants will have tissue samples collected during surgeries or biopsies. These are procedures the participants would have had as part of their standard care. No new procedures will be done just for this study. Researchers may also seek out samples from prior procedures the participant had done. Participants will remain in the study for 6 months. They may have blood drawn again. Researchers may also collect tissue samples from any procedures performed during that time.

This study will examine DNA from Gastrointestinal Tract of cancer patients treated with oxaliplatin to look for a variation (mutation) of the ABCG2 gene that may lead to drug-induced peripheral neuropathy in certain patients. The DNA will be extracted from patients' blood samples and are analyzed for the ABCG2 single nucleotide polymorphism (G34A - rs2231137 and A/A -rs3114018 genotypes) and correlated with peripheral neuropathy grades.

The purpose of this study is to determine whether Monosialotetrahexosylganglioside sodium injection can relieve the neurotoxicity caused by oxaliplatin in GI cancer.

This is an open-label, non-randomized, dose escalation phase I trial to evaluate safety and tolerability of SHR-1210 in patients with advanced solid tumors. The primary objective is to assess safety and tolerability of SHR-1210 and identify recommended phase II doses of SHR-1210 in patients with advanced solid tumors.

Bone metastasis causes bone destruction and skeletal related events (SRE) including compression fracture, hypercalcemia, and spinal cord compression. Therefore, palliative treatments for pain control and local control have become important and multidisciplinary multimodality approach is needed for treatment of bone metastasis. The efficacy of radiotherapy (RT) for bone metastasis is well known. And the results that bisphosphonate decreases SRE in patients with solid tumor and multiple myeloma reported. In previous retrospective reports, the combination of local RT and systemic bisphosphonate was more effective than RT alone. Therefore, Investigators designed a phase II study to evaluate the efficacy of RT in combination with zoledronic acid on pain relief and the safety of RT in bone metastasis patients with gastrointestinal tumors.

At present, there are more and more reports about enhanced recovery after surgery（ERAS）in China, but there is no ERAS treatment standard for gastrointestinal cancer, and there are many factors limiting the development of ERAS. In recent years, due to the development of minimally invasive technology, the establishment of evidence-based medicine model and the development of MDT, it makes a good solid foundation for the clinical application of ERAS. The implementation of ERAS requires the cooperation of surgeons, anesthesia management, nursing, rehabilitation and other teams. As an individualized treatment mode, ERAS focuses on the optimization of treatment for different individuals in order to acquire the best benefit of patients. Therefore, the concept of ERAS is still in the process of continuous improvement and development in China, hoping to explore the Chinese ERAS clinical pathway for gastrointestinal cancer. The purpose of this study is to optimize the clinical pathway of ERAS in the perioperative period of gastrointestinal cancer, and to evaluate the effectiveness and safety of ERAS in gastrointestinal cancer.

Gastrointestinal cancer like Gastric cancer and colorectal cancer are high-incidence tumors worldwide. Surgery is the only curable way. Perioperative treatment can improve the survival of patients. Microsatellite instability-high（MSI-H）are a special subtype of gastrointestinal tumors, accounting for about 15-22%. According to current research, patients with this type of gastrointestinal tumors cannot benefit from traditional perioperative chemotherapy, which directly affects the long-term survival of patients. Because patients with MSI-H have a unique tumor immune microenvironment, thus they are more likely to benefit from immunotherapy. Current studies have confirmed that the use of immunotherapy during palliative care can prolong the survival of patients with MSI-H. In the neoadjuvant treatment stage, according to the previous clinical practice of our center, the use of immunotherapy can make some patients achieve complete postoperative pathological remission. However, in the perioperative treatment stage, the value of immunotherapy is still lack of powerful clinical evidence. Based on this, our group intends to start an observational study to prospectively enroll patients with MSI-H gastrointestinal tumor using immunotherapy during the perioperative period.The primary endpoint is safety while survival outcomes as secondary endpoints. In order to evaluate the safety and effectiveness of immunotherapy during the perioperative treatment stage in MSI-H gastrointestinal cancer
