Active clinical trials for "Carcinoma"

TheraSphere is a medical device containing yttrium-90 (Y-90) a radioactive material that has been used to treat liver tumors. When Y-90 is put into very tiny glass beads (TheraSphere), it can be injected into the liver through a blood vessel. This allows a large local dose of radiation to be delivered to the tumor with less risk of toxic effects from radiation to other parts of the body or to healthy liver tissue.

Skin cancer is the most common cancer in Caucasians. Basal cell carcinoma (BCC) is the most frequent skin cancer with around 44.000 new tumours per year in the Netherlands, and its incidence is still rising. Prior to treatment, a punch biopsy (PB) is taken from the suspected lesion, in order to determine the subtype of BCC. There are three different histological subtypes of BCC, from least to most aggressive: superficial, nodular and aggressive. Based on the most aggressive subtype seen in the PB, a suitable surgical margin is chosen. Surgical excision (SE) is the treatment of first choice in all BCC subtypes according to the Dutch guidelines. Recent developments of non-invasive therapies for superficial BCC might be the first choice of treatment in the future. These non-invasive treatments (photodynamic therapy (PDT), Imiquimod and 5-fluorouracil (5-FU)) have better cosmetic results than SE and are therefore also used in the Maastricht University Medical Center. Drawback is a higher recurrence rate than SE. As nodular and aggressive subtypes grow deeper into the dermis, they have to be treated with SE with a 3 mm and 5 mm margin respectively. If BCC are located in the H-zone, the treatment will be Mohs micrographic surgery (MMS). Unfortunately, 30% of subtypes seen in the PB do not correspond with the subtype seen in the subsequent SE/MMS. The consequence is overtreatment and undertreatment. A potential better or equal way to determine the BCC subtype might be the clinical diagnosis. To our knowledge, there is no literature about the diagnostic value of the clinical diagnosis to determine the subtype of BCC seen in the SE/MMS specimen. We want to confirm the hypothesis that the clinical diagnosis is as good as, or even better than the histological diagnosis by PB to determine the BCC subtype in the subsequent SE/MMS. In this case, patients don't have to undergo an extra procedure, diagnostic route is shortened. - Primary objective: to establish the observed agreement of clinical diagnosis compared to histological diagnosis by to determine the most aggressive subtype of BCC - Secondary objectives: inter-observer and intra-observer variability of dermatologists and pathologists to determine subtype BCC.

Information on the prevalence of advanced/metastatic renal cell carcinoma and its symptom burden is limited in commercially insured adult patients. Additionally, limited information exists on economic burden of adverse events associated with treatments for advanced/metastatic renal cell carcinoma. An objective of the current study is to estimate the incidence, prevalence, and symptom burden associated with advanced/metastatic RCC in a US "real-world" setting. Another objective is to quantify the economic burden of severe adverse events with agents used in management of first line advanced/metastatic RCC (sunitinib, sorafenib, bevacizumab, and pazopanib). This study will employ a retrospective cohort design. Analyses of health insurance claims data from a large commercially insured population will be employed in the current study. Study subjects will consist of all persons, aged ≥18 years, with evidence of advanced RCC between January 1, 2000 and December 31, 2009; these persons will be identified based in part on case-ascertainment algorithms. Analyses will be directed at estimating annual rates of incidence and prevalence of advanced/metastatic RCC, as well as symptom burden and costs of common severe adverse events associated with treatments used in management of advanced/metastatic RCC (sunitinib, sorafenib, bevacizumab, and pazopanib).

The purpose of this study is to confirm that linear quantification of CD3+ cells is a prognostic biomarker in localized colorectal carcinomas.

Eligard is a 6-month depot injection formulation that combines the active ingredient leuprorelin acetate (LA) with a biodegradable polymer matrix (Atrigel® delivery system). The 6-month (45 mg) formulation was approved for the Russian market in 2009. It has been shown to reduce testosterone and prostate-specific antigen (PSA) levels and to be well tolerated in several clinical trials. However, clinical trials are limited by strict patient inclusion and exclusion criteria. Therefore, the current non-interventional study aimed at investigating whether the efficacy and tolerability of the 6-month LA depot formulation could also be confirmed in a broad and heterogeneous patient population encountered in daily clinical practice in the Russian Federation. This study will evaluate total serum PSA and testosterone levels, Quality of Life (QoL) of patients, demographic patient data, diagnosis and diagnostic findings in patients. It will provide analysis in different subgroups of patients depending on previous hormonal treatment and anamnesis of disease.

In this registry study the investigators will collect data about patients' disease, treatment, and response to treatment to include in both our local and national databases. These can then be used by investigators to answer questions about cytoreductive surgery/HIPEC such as how well-tolerated or effective it is in specific populations.

100 patients with metastatic and/or advanced renal cell carcinoma treated with sunitinib (Sutent) will be inclued and followed with standard care plus a call center Principal assumption : the proportion of patients presenting with at least one grade 3 or 4 AE (whether related to sunitinib or not).

This research trial studies molecular features and pathways in predicting drug resistance in patients with castration-resistant prostate cancer that has spread to other parts of the body and who are receiving enzalutamide. Studying samples of blood and tissue in the laboratory from patients receiving enzalutamide may help doctors learn more about molecular features and pathways that may cause prostate cancer to be resistant to the drug.

The purpose of this study is: to investigate the risk factors of HCC among Americans with focus on lifestyle factors and energy balance. to identify single nucleotide polymorphisms (SNPs) and haplotypes that are associated with HCC risk through a genome-wide search. to assess if genetic susceptibility differs by hepatitis virus infection or lifestyle factors, and to explore if there are interplays or effect modifications between genetic factors and viral infection or lifestyle factors.

This surveillance's objectives are: Unknown adverse reactions Incidences of adverse drug reaction Factors considered to have effect to safety and effectiveness
