Active clinical trials for "Penile Neoplasms"

The current project is based on the assumption that a diagnosis of human papillomavirus associated Infiltrating Carcinomas can be made from a blood sample for patient with Cervical Cancer, Vulvar Cancer, Anal Cancer, Oropharynx Cancer, Oral Cavity Cancer or Penis Cancer at any stage of the disease and including surgical treatment for the small tumors.

The project aims to increase HPV vaccination and cervical cancer screening through a web-based mobile health education program called, Wheel of Wellness (WoW) and a brief negotiated interview (BNI). The in-person BNI and WoW system will provide educational resources for participants and their families to learn more about HPV vaccination and cervical cancer screening.

Counteracting misinformation on childhood vaccines remains a priority for public health in industrialized countries. Previous research showed that misinformation-induced vaccine hesitancy particularly concerns very highly or very lowly educated parents, and, especially in Europe, specific groups of immigrants. Misinformation framing directly targets specific sub-population of parents by exploiting different cognitive biases, and specific concerns based on cultural norms: this project aims at testing the effectiveness of similar framing techniques applied to positive information on the HPV vaccine by conducting a Randomized Controlled Trial in Stockholm, Sweden. It randomizes emotionally and scientifically/statistically framed information addressing the specific concerns reported by previous literature.

High 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 AERS 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 relationship between gabapentin exposure and pancreatic cancer and renal cancer is studied in NCT01138124, and supplemental analyses for these cancers are performed in the current study. The FDA recommended GSK also study the relationship between gabapentin and all-cancer sites, as well as cancer at the following specific sites: 1) stomach, 2) anus, anal canal, and anorectum, 3) lung and bronchus, 4) bones and joints, 5) breast, 6) penis, 7) urinary bladder, and 8) other nervous system. The primary objective of this study is to determine whether exposure to gabapentin is associated with an increased risk of developing all-cancer, and these specific cancers in the United Kingdom (UK) General Practice Research Database (GPRD). Each member of the UK population is 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. Subjects are excluded from the GPRD cohort if they have a cancer diagnosis or a history of cancer prior to the cohort entry date. 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. Cases must have no history of any other cancer diagnosis prior to the index date. Controls are required to be free of cancer diagnosis in the database up to the control's index date. Data on gabapentin prescriptions are obtained for cases and controls from study cohort entry to the index date. Gabapentin exposure will be assessed as ever/never, number of prescriptions, cumulative dose, and cumulative duration, with a 2 year lag period incorporated to control for protopathic bias (gabapentin prescription for initial pain symptoms of undiagnosed cancer) and latency (time between cancer onset and specific GPRD cancer diagnosis). Crude and adjusted odds ratios and 95% confidence intervals (CI) will be produced from conditional logistic regression models, with additional analyses evaluating for dose-response. Covariates include indications for gabapentin use and risk factors for each cancer.

In this study we evaluate the feasibility of intraoperative visualization of penile and tongue tumours using the fluorescent tracer EMI-137.

This study explores penile squamous cell carcinoma (PSCC) in Brazil, a rare cancer associated with factors like poor hygiene and HPV infection, using next-generation sequencing to investigate its genomic profiles in 24 deceased patients with advanced PSCC.

The presence of metastatic disease in the lymph nodes within the groin is the most important factor in predicting the long-term outcome for patients diagnosed with penile cancer. In the majority of patients diagnosed with penile cancer obvious abnormalities cannot be felt in the groin even though the cancer may have already spread to the lymph nodes in the groin. In these patients, a procedure called Dynamic Sentinel Lymph Node Biopsy (DSLB) is required to determine if the cancer has spread to the lymph nodes in the groin. In DSLB a radioactive substance is injected at the site of the penile cancer and then travels to the lymph nodes in the groin which are then biopsied. This procedure requires a general anaesthetic and an in-patient hospital stay. In approximately 20% of patients with penile cancer obvious abnormalities can be felt in the lymph nodes in the groin. However, any abnormality detected may not necessarily be due to metastatic disease. In order to confirm if metastatic disease is present in the lymph nodes of these patients a biopsy is also required. However in these patients the lymph nodes are detected and biopsied using an ultrasound scan rather than by passing a radioactive substance into the body. MRI-PET is a new procedure which combines conventional MRI (Magnetic Resonance Imaging) and PET (Positron Emission Tomography) scans into one scan. MRI - PET scans create very clear pictures of internal body structures. MRI-PET is a non-invasive procedure which can be performed on an out-patient basis. The accuracy of MRI-PET in detecting metastatic penile cancer is not known. The main purpose of this study is to establish the effectiveness of MRI-PET compared to DSLB and ultrasound guided biopsy in detecting the presence of metastatic disease in the lymph nodes of patients with penile cancer. If effective, MRI-PET could replace the invasive procedures currently required for detection of metastatic penile cancer.
