Filter by:Earlier detection of disease recurrence will enable greater treatment options and has strong potential to improve patient outcomes. This project is translational and has the potential to lead to future translational research opportunities, including interventional trials in which therapeutic escalation is offered at the early circulating tumor DNA (ctDNA) molecular residual disease (MRD) detection timepoint. Ultimately, the integration of ctDNA into the clinical workflow has the potential to enhance cancer diagnosis, treatment, surveillance, and prognosis, and guide clinical decision-making in this era of personalized precision medicine.
The purpose of this prospective, non-randomized, single-center pilot exploratory study is to investigate whether established circulating tumor cell (CTC) cultures have a similar response to targeted therapy treatment as the in vivo (patients') disease.
This study will investigate the effects of atezolizumab on select cancer types in people whose analysis of tumour DNA and RNA indicates they may be sensitive to atezolizumab. This study aims to determine if the information from the cancer genome analysis corresponds with the effects of atezolizumab on individuals and their cancer. This is a Phase 2 study, which is undertaken after preliminary safety testing on a drug is completed, and will involve approximately 200 participants. Participants are assigned to one of 8 cohorts based on their primary tumour type: breast, lung, gastrointestinal (GI), primary unknown, genitourinary (GU), sarcoma, gynecological, and 'other' cancer types. Participants in all cohorts will receive the same dose of atezolizumab (1200 mg every 3 weeks). In the first stage for each cohort, 8 participants will be enrolled and if no participants respond to treatment, enrollment to that cohort will be closed. If 1 or more participants respond to treatment, up to 16 additional participants will be enrolled to that cohort. Participants continue on treatment until they no longer may benefit from the treatment or they decide to stop treatment.
This research study is for patients with an advanced cancer that carries a mutation in a gene called KRAS. Genes are parts of our DNA which carry instructions for a cell (the smallest component of an body part). In many cancers, the KRAS gene contains errors (mutations) which allows the tumors to grow. The purpose of this study is to determine if combination treatment with atezolizumab, cobimetinib, and hydroxychloroquine is safe, and if it will decrease the size of the tumor and prolong life in patients whose tumors contain this mutation. Cobimetinib and atezolizumab are both approved by the FDA for use in other cancers, but not in some cancer types being studied in this trial. Hydroxychloroquine is FDA approved to treat malaria and other conditions, but has also not been approved for these cancer types. Preliminary results have shown that this combination of drugs is effective at killing cancer cells and shrinking tumors in several KRAS-mutated cancers in animals.
The clinical study of modern therapies on flora changing in blood, oral cavity, urethra and intestinal tract of patients with malignant tumors. The study is observational. Patients are diagnosed cancer based on pathology or cell biology. The sample of flora will be obtained from their blood, oral cavity, urethra and intestinal tract, mainly to study what modern therapies lead to the influence of microecological environment including diversity and abundance of bacteria in patients who received malignant tumors. Immunological examination and Blood biochemistry evaluation include the number ratio, activity and function of immune cell, the immune cell marker(CD3, CD4, CD8, etc), C-reactive protein(CRP), tumor necrosis factor(TNF), Inflammatory stimulant factor(IL-2, IL-6, etc), tumor marker(CEA, AFP, etc),etc. Clinical evaluation includes image data(CT/MRI), quality of life(QOL), no disease progression survival, total survival, objective disease remission rate, etc.
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.
This study aims to determine the safety and tolerability of TMV-018 when given alone or in combination with the prodrug 5-Fluorocytosine (5-FC) or an anti-PD-1 checkpoint inhibitor in patients with gastrointestinal tumors. Furthermore, the maximum tolerated dose (MTD) and recommended Phase II dose of TMV-018 shall be determined.
The MA-PPING is a multicenter prospective observational study that includes patients undergoing surgery for gastrointestinal cancer. The study aims to map the oral and gut microbiome of patients diagnosed with pancreatic, esophageal or colorectal cancer during their surgical patient journey from the moment of diagnosis until full recovery (three months after surgery).
The main purpose of this research study is to determine if the use of a nutritional supplement and exercise improve or worsen cachexia.
IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.
