Active clinical trials for "Carcinoma"

This multi-center, observational study involves reviewing the medical records of approximately 100 adult participants diagnosed with advanced BCC from 01 January 2005 until 31 December 2010. Participant records will be analyzed to identify participant characteristics, treatment patterns and clinical outcomes.

Investigators hypothesise that the use of transarterial chemoembolisation (TACE) after liver resection in patients with hepatocellular carcinoma can eradicate residual cancer cells in the liver and thus improve survival of patients with high risk factors for residual tumor. The aim of this study is to compare the survival of patients with high risk factors for residual tumor undergoing liver resection plus post-operative TACE versus liver resection alone.

The prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in the United States (US) is relatively low. However, immigrant populations in the US from Asia and sub-Saharan Africa have substantially higher prevalence than the general population and are consequently at a significant risk for hepatocellular carcinoma (HCC). Indeed, the age-adjusted incidence rates for HCC in the US have tripled from 1975 to 2005. As the population demographics have changed, the 2000 US census estimated the number of Somalis in Minnesota at 25,000 but current estimates put the number at around 50,000 due to primary refugee arrivals as well as secondary immigration from other states. There is no available data for Somali immigrants in the US on HBV and HCV prevalence, HBV and HCV genotypes/subgenotypes, and genetic and immunologic risk factors predisposing Somalis to HBV and HCV and the subsequent development of HCC. Therefore. this study will fill these gaps in the Somali population to understand the relative importance of HBV and HCV infections in causation of HCC. Besides Somalis, Minnesota is also home to large other African immigrant communities. According to the Minnesota Department of Health (MDH), in 2013, the highest rates of chronic HBV cases where reported among Asian or Pacific Islanders (3,638 cases per 100,000 persons) followed by Black or African Americans (2,078 cases per 100,000 persons). Additionally, Minnesota receives a large number of new refugee's resettlement. It is important to improve the identification of chronic HBV and HCV infections among Somali refugees and immigrants in Minnesota through well-designed community-wide screening efforts. Since we know that African immigration to Minnesota is the third highest in the US, this unique population might be a contributing factor to the increased burden of hepatitis and liver cancer complications in the state of Minnesota. Findings from HBV and HCV screening among Somalis suggest that other immigrant African populations from high viral hepatitis endemic regions, such Ethiopia, Liberia, and Kenya, are also at substantial risk of HBV, HCV and HCC. Unfortunately, very little research has been conducted in the US on the burden of hepatitis and liver cancer in African Immigrants from areas of high endemicity of hepatitis B and hepatitis C. Therefore, the goal of is to identify HBV and HCV and the role viral genetics and immune response among African immigrant communities from Kenya, Liberia, and Ethiopia.

Intraoperative tumor localization and resection can be enhanced using intraoperative fluorescence imaging and radiodetection. Girentuximab specifically recognizes carbonic anhydrase IX expressed on > 95% of renal cell carcinoma (RCC). Therefore Indium-111-DOTA-girentuximab-IRDye800CW is a perfect dual-labeled antibody for dual-modality image-guided surgery in RCC. The aim of this study is to assess the feasibility and safety of intraoperative dual-modality imaging with Indium-111-DOTA-girentuximab-IRDye800CW in renal cell carcinoma patients.

This prospective, observational, cohort study is designed to assess the effectiveness and safety outcomes of vismodegib and to assess actual day-to-day disease and participant management by the physician.

Increasing rates of highly malignant hepatocellular carcinoma (HCC) and biliary tract cancers (GBTC) observed in Western populations may be related to obesogenic lifestyle factors and their metabolic consequences, such as metabolic syndrome (MetS), inflammation and altered production of bile acids (BA). Such lifestyle behaviours may induce changes in the gut microflora which in turn affect BA profiles, increasing their carcinogenicity. Some elevated BA may be oncogenic in exposed liver, bile ducts and gall bladder. Vertical sleeve gastrectomy may change bile acid composition. The aims of this study are: whether specific presurgical bila acid profiles are predictive of efficacy of vertical sleeve gastrectomy, reflective of liver function and metabolic dysfunction; whether specific presurgical bile acid profiles are predictive of the efficacy of sleeve gastrectomy

This clinical trial is designed to evaluate the efficacy of single immediate intravesical chemotherapy instillation in the prevention of bladder recurrence after diagnostic ureteroscopy for upper tract urothelial carcinoma (UTUC) patients.

To study if the addition of HAIC following complete removal of early stage liver cancer of HCC will prevent or delay the recurrence of the disease. Half of the participant will receive two cycles of the HAIC after the hepatectomy, while the other half will return to the baseline surveillance schedule.

The aim of this pilot study is to correlate the sorafenib plasma concentration to observed toxicity and to the disease control rate in 100 patients undergoing a palliative treatment of hepatocellular carcinoma (HCC). If some correlations are observed, we will consider planning a larger interventional study to adjust sorafenib daily dose to plasma concentration.

The high dose per fraction (>10Gy/fraction) used in Stereotactic Ablative Body Radiotherapy (SABR) has been shown to be more effective at local tumor control than treatments employing more conventional dose fractions. The mechanisms for this are currently under debate. One possible mechanism for this increased effectiveness is that high dose/fraction causes significant vascular damage to the tumor. This study hopes to measure vascular integrity pre and post SABR treatment using kinetic models obtained from dynamic contrast enhanced CT.
