Active clinical trials for "Carcinoma"

The purpose of this study is to better understand the natural history of oropharyngeal carcinoma (OPC), with or without an association with the human papilloma virus (HPV). For this study, the investigators plan to collect blood from OPC patients prior to treatment and at six subsequent time points.

In recent years, fasting or the use of special diets (ketogenic, high protein, etc.), whether or not associated with food supplements, have increased substantially, particularly in oncology with the idea of improving for some of them, the tolerance of the proposed treatments, in particular emetogenic chemotherapy, or even to improve the prognosis. Although there are preclinical data on cell cultures and in rats, the clinical data supporting these practices are very fragmented, with few trials carried out and only including small cohorts, mainly in the context of breast cancers. It is therefore very difficult to respond objectively to patients asking the question of the merits of these changes in dietary practices in the management of their cancer. The investigators want to carry out an inventory of the dietary practices of participating patients and their potential interest in fasting or special diets by means of a self-administered survey completed by the patient at diagnosis before treatment. This semi-quantitative self-administered survey (answers in never / sometimes / regularly / systematically) was developed by the nutrition and radiotherapy team of the Georges-Pompidou European Hospital because there was no validated medical questionnaire on fasting or the use of special diets in oncology

Treatment with adjuvant radiotherapy modulates immune system in many diseases as witnessed by dynamic changes of humoral and cellular immunity. Moreover, the persistent lymphopenia after radiation therapy is a negative prognostic factor. This study is aimed to explore the changes in immune-cell populations during radiotherapy given as adjuvant treatment for high-risk cutaneous squamous cell carcinomas and to correlate them with patient's outcome.

Every patient with HCC (Hepato-Cellular Carcinoma) with main portal vein thrombosis will be screened for presence of large esophageal varices and will be randomized between non-selective beta blocker versus primary endoscopic variceal ligation. They will be followed to assess the rate of reduction of index bleed rate as well as survival difference between the groups.

Taking part in medical research usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This study will admit a wide range of data on the clinical trial experience of Merkel cell carcinoma patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future Merkel cell carcinoma patients.

One of the main reasons for treating actinic keratoses (AK) is the wish to lower the risk of progression of AK to squamous cell carcinoma (SCC). This risk is in the order of 1 per 1000 AKs per year, which is in itself a small risk, but since patients can have dozens of AKs and the disease is chronic the cumulative risk for a patient can be substantial. In this extension protocol of trials LP0084-1193, -1194, -1195 and -1196, LEO will study the incidence of SCCs and other skin neoplasia in vehicle and ingenol disoxate treated patients over a period of 2 years, so that the total follow-up time for each patient will be 3 years and 2 months.

The study will be a randomized trial that will compare two techniques of abdominal paracentesis in patients with suspected peritoneal carcinomatosis. The patients will undergo abdominal paracentesis by the standard technique and a rollover technique. In the standard technique, the patients will lie flat for 10 minutes and abdominal paracentesis will be taken for ascitic fluid cytology. In the rollover group, patients with suspected peritoneal carcinomatosis will be rolled over thrice laterally on each side by 90 degrees and sample will then be obtained for ascitic fluid cytology. both the samples will be processed by blinded cytopathologist for tumour cellularity and diagnostic yield.

Purpose: To evaluate the utility of simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) in characterizing the molecular subtypes of clear cell renal cell carcinomas (ccRCC) to potentially inform prognosis and treatment decisions. Participants: Seventeen subjects diagnosed with clear-cell renal cell carcinoma (ccRCC) will be imaged in a single session on PET-MRI. Procedures (methods): The investigators will image 17 ccRCC subjects on simultaneous PET-MRI and quantify the metabolically-active fraction of the tumor from images. Ten core samples will be taken from each tumor post-surgery and classified as ccA or ccB subtype using transcriptome analysis. The imaging-based measures will be correlated with the fraction of tumor cores classified as ccB.

The primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.
