This study is a non-randomized, open-label, multi-cohort, multi-site, pilot feasibility therapeutic trial. The study will enroll 20 patients across 4 cohorts (CRC, gastric, PDAC, and HCC/intra-hepatic-/extra-hepatic-, gall bladder adenocarcinomas) diagnosed with histologically confirmed GI cancers. These patients will have already completed all Standard of Care (SOC) treatments (including neoadjuvant, surgery, local therapies, and/or adjuvant therapy as applicable), as defined by the treating primary physician or research team, with curative intent but have a positive SignateraTM tumor-informed ctDNA test and NED radiographically by standard imaging within 28 days prior to enrollment and within 1 year of completing all curative-intent therapy. All patients will be treated with intravenous (IV) atezolizumab 1200 mg IV and bevacizumab 15 mg/kg on Day 1 of 21-day cycles until disease recurrence, ctDNA POD, unacceptable toxicity, or subject withdrawal of consent with a maximum 12 month total duration of study therapy. Atezolizumab and bevacizumab drug will be provided.
This phase Ⅱ study was designed to evaluate the efficacy and safety of mFOLFIRINOX as first-line treatment for metastatic pancreatic cancer in China.
This randomized phase I/II trial is studying the side effects and best dose of monoclonal antibody therapy when given together with gemcitabine hydrochloride and erlotinib hydrochloride and to see how well they work compared with giving gemcitabine hydrochloride and erlotinib hydrochloride alone as first-line therapy in treating patients with metastatic pancreatic cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving erlotinib hydrochloride and gemcitabine hydrochloride together with monoclonal antibody therapy may kill more tumor cells.
In this study 250 µg of G17DT was administered at Weeks 0, 2 and 6 in order to demonstrate non inferiority compared to gemcitabine in prolonging survival in advanced pancreatic cancer.
Pancreatic cancer is the most lethal malignancy of human being. Surgery is the only potential cure of pancreatic cancer. The invasion of major abdominal arteries is one of the most important factor restricting surgical intervention. For artery-involved pancreatic cancer (ai-PC) patients, pre-operative adjuvant therapies, especially the neoadjuvant chemotherapy, has brought exciting postoperative survival. Yet due to the potential screening effect of this treatment strategy, nearly half of ai-PC patients failed to benefit from surgery because of disease progression, adverse reactions of adjuvant treatment and other reasons. Artery divestment for the treatment of ai-PC firstly reported by our center, can significantly increase resection rate and produce overall survival benefit in some patients. This study is to explore whether up-front surgery with artery divestment combined curative pancreatectomy or the chemotherapy-first strategy would be more beneficial for ai-PC patients' survival.
Subjects will be randomized to treatment group either receiving up-front artery divestment combined pancreatectomy (Surgery Group) or adjuvant chemotherapies (Chemo Group). In Surgery Group, an artery divestment combined pancreatectomy will be performed if no pre-operative contra-indication or intra-operative metastasis were revealed. Post-operative adjuvant chemotherapies were prescribed according to performance status. In Chemo Group, adjuvant chemotherapy of gemcitabine or gemcitabine + cisplatin will be utilized according to performance status. After 2 circles of adjuvant chemotherapies, patients will be reevaluated and curative operation would be attempted if without disease progression.
Overall mortality at one year after randomization will be the primary endpoint. Other parameters as overall survival after 2 and 3 years, median survival, disease-free survival, margin status of subjects receiving curative surgery, etc. will also be observed.
The number as well as the caliber of plastic stents used for EUS-guided PFC drainage are controversial in current practice [Lin et al., 2014]. The timing of necrosectomy in WOPN drainage continues to be debated. To date, no comparative studies have been conducted to investigate the ideal timing for stent removal. Thus, the aim of our study is to:
* Assess the technical success rates, clinical success rates and potential complications of the different techniques for the best drainage of PFCs as regard type, caliber and number of plastic stents and ideal timing for stent removal.
* Compare between early vs late intervention for complete endoscopic necrosectomy of WOPN as regard technical success rates, clinical success rates, potential complications and number of sessions needed.
This study is a Phase I/II study. In Phase I of this study, the objective is to determine the maximum tolerated dose (MTD) of combination therapy with Aroplatin and gemcitabine (Gemzar®) in subjects with unresectable, locally advanced and/or metastatic pancreatic cancer. In Phase II, the primary objective is to evaluate survival after therapy with Aroplatin and gemcitabine at the identified MTD in subjects with unresectable, locally advanced and/or metastatic pancreatic cancer. Secondary objectives are to evaluate the severity and quantity of adverse events and determine the proportion of non-progressors and the progression-free interval.
A Totally Implantable Venous Access Device (TIVAD) that is no longer in use for intravenous therapy, should be flushed at established intervals to promote and maintain patency. No consensus has been established regarding the optimal duration of the interval between 2 maintenance sessions. This exploratory study will focus on catheter status under the current 3-monthly flush regimen.
The purpose of this study is to see if the use of 68Gallium- positron emission tomography and computer tomography (PET/CT) scans along with NETSPOT® (Advanced Accelerator Applications USA, Inc.) can better define the localization of Neuroendocrine tumors enhancing the surgical removal of Neuroendocrine tumors (NETs).
Local tumor ablation is among the major anti-tumor modalities worldwide. Given the number of changes that have taken place in the field of tumor ablation in the past 10 years, it is our intention to ensure that this highly utilized standardization continues to remain relevant as it unites all investigators and clinicians practicing interventional oncology by providing a common language to describe therapies and outcomes, develop studies, and communicate with other medical specialties. In an attempt to attain greater Asian-wide adoption, the investigators will initiate the registry system for local tumor ablation in Taiwan, China, Korea, Singapore, Hong Kong and Thailand.
