Gabapentin and Risk of Pancreatic Cancer and Renal Cancer (GPRD)
Renal Pelvis CancerRestless Legs Syndrome8 moreHigh doses of gabapentin are associated with pancreatic acinar cell tumors in rats, but there has been no post marketing pancreatic carcinogenicity signal with gabapentin as reported by spontaneous reports in the Adverse Events Reporting System or in the published literature. In a published case-control screening study of the association of gabapentin with 55 cancers, the only cancer that met the screening criteria for possibly increased cancer risk with gabapentin exposure was renal (including renal pelvis) cancer. This association was judged to be likely due to or substantially accentuated by confounding by cigarette smoking, hypertension, and lifestyle (Cancer Causes Control 2009;20:1821-1835). The primary objective of this study is to determine whether exposure to gabapentin is associated with an increased risk of developing pancreatic cancer or renal cancer in the United Kingdom (UK) General Practice Research Database (GPRD). Almost all members of the UK population are registered with a General Practice, which centralizes the medical information not only from the general practitioners themselves but also from specialist referrals and hospital attendances. Over 487 General Practices contribute data to the GPRD. The study cohort from which cases and controls are drawn is all subjects in the GPRD 1993-2008. Gabapentin was approved in the UK in May 1993. Entry into the study cohort begins Jan 1, 1993 for all those who are registered in GPRD before that time, and at the time of registration if later than Jan 1, 1993. Patients with a first diagnosis of the respective cancer 1995-2008 are risk set matched with up to 10 controls within the same General Practice for age at cohort entry (within two years), sex, and year of entry into the study cohort (within one year). For cases, the index date is the date of first diagnosis of the respective cancer. The index date for controls is set as the date at which the follow-up time from cohort entry is the same as the case. The index date is chosen so as to give the control equal follow-up time to that of the case for ascertainment of use of gabapentin. Cases and controls will be required to have at least 2 years of follow-up in the study cohort before their index date. Data on gabapentin prescriptions are obtained for cases and controls from study cohort entry to the index date. Crude and adjusted odds ratios and 95% confidence intervals (CI) will be produced from conditional logistic regression models, with additional analyses evaluating for latency and dose-response. For pancreatic cancer, covariates are smoking, body mass index, diabetes, epilepsy, neuropathic pain, and chronic pancreatitis. For renal cancer, covariates are smoking, body mass index, diabetes, hypertension, diuretic use, epilepsy, and neuropathic pain.

CarcinomaRenal Cell2 moreRenal cell carcinoma accounts for roughly 3 % of all cancer. It is a rather aggressive cancer type, which means that patients who present with an advanced disease have a rather poor prognosis. When this study has been started the standard therapy for patients has been cytokines, which might be accompanied by significant toxicities or might fail the therapeutic goal. In these cases sorafenib can be a feasible therapeutic option. This non-interventional study has been created and is being conducted to collect clinical data on the patients' therapy with sorafenib in an everyday treatment schedule. The main goal of this study focuses on patient characteristics and tumor status in RCC treated with sorafenib as well as the treatment duration and safety of sorafenib under everyday treatment conditions.

Kidney CancerRATIONALE: Studying samples of blood and/or tissue in the laboratory from patients with kidney cancer receiving sorafenib may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how well patients will respond to sorafenib. PURPOSE: This research study is looking at the DNA in blood and/or tissue samples from patients with primary kidney cancer receiving sorafenib on clinical trial MRC-RE05-SORCE.

Cardiovascular Effects of Sunitinib Therapy (CREST)
Renal Cell Carcinoma 4Tyrosine kinase inhibitors such as sunitinib are used in the treatment of renal cell carcinoma and have significant off-target effects with cardiac toxicity and resultant ventricular cardiac dysfunction being a major concern. However, the mechanisms of these effects in humans remains poorly defined, as are the clinical methods to risk stratify and identify patients who will ultimately suffer from cardiac dysfunction. The goal of this multi-center study is to characterize the cardiovascular measures of cardiac function; 2) comprehensive measures of arterial function and left ventricular afterload; 3) biomarkers reflective of the pathophysiologic alterations. Through this work, the investigators will translate our basic understanding of sunitinib cardiotoxicity to humans and identify early predictors of sunitinib cardiotoxicity.
SUTENT® In The First Line Treatment Of Renal Cell Carcinoma
Renal Cell CarcinomaThis non-interventional study includes patients with advanced and/or metastatic renal cell carcinoma who are treated with SUTENT and who did not receive any other systemic therapy before. The aim of the trial is to increase knowledge about quality of life, safety, efficacy and tolerability under conditions of routine use of Sutent. The individual observation period of each patient will be 1 year.
Sorafenib in Elderly mRCC
CarcinomaRenal CellThis prospective, single arm, multi-center pilot study includes 120 mRCC patients over 65 years, no prior systemic treatment, determined to be candidates for systemic therapy by the investigator. The treatment with Sorafenib should comply with the recommendations written in the local product information. The primary endpoint is overall survival. The secondary endpoints including other effectiveness points, safety and patients characteristics. With 120 completed patients, if the observed survival rate at 12 months is 60%, the width of a 95% confidence interval will be approximately 18%.
