Filter by:The primary objective of this phase I dose escalation study is to determine the maximum tolerated dose of TH-302 when administered with doxorubicin via trans-arterial chemo-embolization (TACE) in patients with hepatocellular carcinoma (HCC) who are not transplant candidates and have unresectable disease. HCC is the second leading cause of worldwide cancer death and is generally incurable without liver transplant. TACE can convert about 40% of these patients to transplant candidates. Additionally, in non-transplant HCC patients, TACE confers statistical improvements in overall survival. Selective HCC arterial catheterization during TACE allows for the delivery of concentrated drugs to the liver tumor but the optimal TACE chemotherapy regimen has not yet been determined. TH-302 is a hypoxia inducible agent that can be activated in the hypoxic environment induced by TACE.
i. To determine whether Confocal Laser Endomicroscopy (CLE) with optical biopsy and targeted mucosal biopsy improves the diagnostic yield of gastric IM/IN/CA in high risk populations compared to WLE with standard biopsy protocol. ii. To determine whether CLE with optical biopsy and targeted biopsy, as compared to WLE with standard biopsy, can reduce the number of biopsies needed per patient for detection of gastric IM/IN/carcinoma without the loss of corresponding diagnostic yield. iii. To compare the sensitivity and specificity of CLE with WLE for the detection of gastric IM/IN/CA.
TACE is widely used in patients with unresectable HCC. However, it is a non-curative approach; thus ,strategies to further improve the survival of these patients are needed. Sorafenib is regarded as standard treatment for advanced HCC. It is the first systemic therapy to demonstrate a significant survival benefit in HCC patients.The hypothesis is that the combination of TACE with sorafenib could improve the survival of patients with unresectable HCC.
Optical coherence tomography (OCT) is an imaging technique which shows the internal structure of living tissue (in vivo). It is safe, quick and painless to perform, and does not damage the tissue in any way. Recent advances in the technology mean that it can now be used to take images of the internal structure of the skin. This is useful because certain conditions, such as skin cancers, alter this structure. At present a suspected skin cancer is identified by taking a sample (a biopsy) which is analysed under the microscope to confirm the diagnosis. The cancer is then excised including a margin of apparently healthy-looking skin around it to ensure that the entirety of the tumour is removed. The excised tumour is then analysed again under a microscope to confirm that it was indeed completely removed (histology), after which a further operation is required to repair the defect. The purpose of this study is to evaluate OCT imaging of a particular type of skin cancer called a basal cell carcinoma (BCC), and in particular BCCs affecting the skin around the eyes (periocular). The study will compare the ability of OCT to define the margin of the BCC with the current 'gold standard' of histology. OCT could potentially improve the investigators ability to define the margins of the tumour before surgery and become a guide for minimally invasive surgery. The preservation of healthy tissue represents a priority, particularly in the area of the skin surrounding the eye.
Transarterial chemoembolization (TACE) is widely used for unresectable hepatocellular carcinoma (HCC). However, the hypoxia caused by TACE in surviving tumor cell leads to release of angiogenic and growth factors contributing to poor outcome. Sorafenib can block tumor cell proliferation and angiogenesis. The hypothesis is that patients with unresectable HCC may benefit from sorafenib in combination with TACE.
Evidence from laboratory studies suggests that aspirin and tea polyphenols may have an antineoplastic effect in esophageal squamous cell carcinoma (ESCC). To assess the safety and efficacy of aspirin and tea polyphenols for preventing ESCC, the investigators designed this double-blind, randomized controlled clinical trial. Research project is planned to recruit 10,000 participants with the ages of 40-60 years in Fengfeng city, Hebei province, China, which has been known as a high incidence region of ESCC. All the participants receive endoscopic examination. Lugol's chromoendoscopy is used to identify esophageal unstained lesions (USLs). The location and size of each USL will be recorded followed by collecting biopsy samples from each USL. Participants with USL are randomly assigned to receive 100 mg/d of aspirin (n=200), 100 mg/d of tea polyphenols (n=200), or placebo (n=200) for six months. Follow-up consists of 2 endoscopic surveillance cycles (the first interval will be at six months and the second at 3 or 5 years later). The primary outcome measure was occurrence of high grade dysplasia and invasive ESCC. Secondary outcome was the mortality of the participants and adverse events.
This research trial collects information about types of treatment and the cost of these procedures in women with elevated genetic risk for ovarian cancer who participated on the Gynecology Oncology Group (GOG)-0199 trial. Gathering information about women at elevated genetic risk for ovarian cancer may help doctors learn more about risk reduction procedures and the cost of these procedures.
The purpose of this study is to determine whether liver transient elastography performed before the surgical procedure is able to predict liver failure in patients undergoing hepatectomy for hepatocellular carcinoma.
Hepatocellular carcinoma (HCC)is the most frequent primitive tumour of the liver. Recently, several research studies reported that 11C-choline PET has shown a high detection rate of well differentiated HCC, which is an early stage of primary liver cancer. The aim of this study was to prospectively evaluate the diagnostic accuracy of 11C-choline PET-CT to detect HCC in cirrhotic or non cirrhotic patients.
Persistent replication of HBV (47-55%) is frequently found in patients with HCC, which in turn leads to deterioration of liver reserve. Moreover, a large proportion of HCC patients who underwent curative therapy died from progressive liver decompensation rather than recurrence of cancer. It had been proved that anti-viral therapy for hepatitis C virus (HCV)-related HCC patients could reduce the rate of tumor recurrence after surgical resection. This is a prospective study to evaluate the efficacy of ETV therapy in chronic hepatitis B patients after receiving RFA therapy for HCC.
