Active clinical trials for "Carcinoma"

This study will evaluate the usefulness of plasma proteasome levels as a tumor marker of hepatocellular carcinoma (HCC) by studying their variation following curative treatment of HCC. The hypothesis of the study is that plasma proteasome levels will decrease following curative treatment, and that proteasome levels could be used as a marker to detect early recurrence.

TACE possibly plays a significant role in contributing to a subgroup of surviving residual tumor tissue which is characterized by more aggressive biology. This explains the strong scientific rationale for exploring the role of anti-angiogenic therapy such as sorafenib to remedy and strengthen the therapeutic efficacy of TACE to combat liver cancers. Sorafenib plays a prominent auxiliary role by further suppressing the tumor growth and prolonging the time to recurrence and progression. Performing TACE under sorafenib administration may have synergic effect on hepatic tumoral lesions.

A randomized, double-blind, controlled trial was conducted evaluating the efficacy of Oligo-Fucoidan with the molecular weight ranged from 500 to 800 Da. as a supplemental therapy in patients with metastatic colorectal cancer. The previous study results demonstrate the advantages of Oligo-Fucoidan in improving the disease control rate. The previous study might provide insights into the development of cancer treatments, particularly in the combination of natural or herbal products with chemotarget agents.

This clinical trial studies cognitive function in men with prostate cancer treated with androgen receptor directed therapies such as abiraterone acetate and enzalutamide. The investigators use MRI imaging (non-invasive, non-contrast) to see whether there are changes in brain structure or activity related to treatment that may be related to changes in cognitive function. The investigators are also looking for genetic variations that might make patients more or less sensitive to cognitive changes during treatment for prostate cancer.

To date, the majority of studies that have evaluated the efficacy of microwave ablation (MWA) in the treatment of hepatocellular carcinoma (HCC) lesions in cirrhotic patients and compared its efficacy with that of percutaneous radiofrequency ablation (RFA) for local recurrence and survival have been retrospective. There have been no prospective randomized studies comparing percutaneous microwave ablation (PMWA) with RFA for ablated tumour volume, the response after one session, local recurrence rates in the first year, complication rates and survival at 3 and 5 years for HCC lesions > 2 cm in patients with Child-Pugh A and B cirrhosis. The hypothesis the investigators wish to explore is that though the 2 methods are equivalent for lesions ≤ 2 cm, MWA could show better efficacy with a similar risk for lesions > 2 cm and for lesions close to vessels ≥ 3 mm in diameter, as shown in retrospective studies.

In France, the incidence of head and neck squamous cell carcinomas (HNSCC) is 16 000 new cases/year. During these last years, many new chemotherapies and targeted therapies have been developed improving significantly the overall survival of patients notably anti-HER molecules. In inoperable recurrent and/or metastatic HNSCC, the best treatment is based on an anti-Human Epidermal Growth Factor Receptor (EGFR) antibody, targeting Human Epidermal Growth Factor Receptor 1 (HER1), the Cetuximab combined with platinum +/- 5 Fluoro Uracil (5FU): " Extreme protocol ". However, no clinical or biological criteria predictive of drug efficacy have been reported yet. Thus, the development of such a predictive factor is an urgent need in HNSCC at both the clinical and pharmacy-economic level, to propose the best personalized treatment. One idea would be to enumerate and characterize the circulating tumor cells (CTC) which could give us an early evaluation of the therapeutic efficiency. In this context, the investigators have developed an innovative technology, the EPISPOT assay (patent of the University Medical Center of Montpellier), that allows the detection & characterization of viable CTC in the peripheral blood. The EPISPOT technology has been already evaluated in the breast and prostate cancer.Thus, the investigators would like for the first time to perform a prospective study on a cohort of patients treated following the Extreme protocol, with this technology, to assess the predictive value of CTC count. The investigators will use the CellSearch® system as the reference test.

Respiratory-gated, volumetric-modulated arc therapy will be used for the clinical development of high dose rate Stereotactic Body Radiotherapy (SBRT) in inoperable hepatocellular carcinoma (HCC). These treatments should enhance local control, progression-free survival and potentially overall survival in HCC patients. The investigators will also examine the mechanism of tumour and microenvironmental response to high dose radiation, and search for potential biomarkers to optimize and individualize therapy. Pre-treatment and follow-up PET/CT imaging with 11C-choline, 18F-fluorodeoxyglucose (FDG) and CT perfusion will examine in-vivo changes in proliferation, glycolysis, and the tumour vasculature, respectively, and blood samples will look for immunologic biomarkers of tumour response.

The aim of high dose radiotherapy treatment is to deliver enough radiation to the tumour to kill all the cancer cells while at the same time giving a low dose of radiation to the normal parts of the body to reduce the side effects of treatment. This requires the cancer specialist to accurately identify the areas of cancer on a computed tomography (CT) scan. Positron emission tomography computed tomography (PETCT) scans use radioactive sugar that is injected into the patient. This sugar goes into cancer cells and shows up as a bright spot on the PET scan, allowing the doctors to see tumours more accurately. Some cancers move with breathing, for example lung, pancreas and oesophageal (or gullet) cancers. Fourdimensional CT scanning (4DCT) is a special type of CT scan that allows the motion of the tumour to be seen and measured accurately. This information can then be used to help ensure that the radiotherapy correctly treats the moving tumour. The aim of this study is to see if there are possible benefits to combining PET with 4DCT to get a 4D PETCT scan for tumours that move with breathing. This study is divided into three cancer types; lung, lower oesophagus and pancreatic cancer. First the investigators are going to test the use of 4D PETCT in the radiotherapy planning of these tumours to see if it helps the doctor to identify the cancer. Secondly, the investigators are going to see if the 4D PETCT helps to show areas within the cancer that are potentially more active. This might then allow us to target a higher dose to these areas, which could potentially improve the chance of controlling and curing the cancer. Patients' standard treatment will not be altered by participating in the study.

This randomized clinical trial is studying two different symptom management programs to see how well they work compared with usual care in patients with recurrent or persistent ovarian cancer, fallopian tube cancer, or primary peritoneal cancer. Developing a symptom management plan may help relieve symptoms related to cancer or cancer treatment and help improve quality of life.

Obstructive sleep apnea (OSA), one of the most frequent respiratory diseases, could represent a major worsening factor in a non alcoholic steatohepatitis and neoplastic context. Our hypothesis is that OSA promotes the prevalence of HCC related to NASH. This national, multicenter study aims to compare the prevalence of OSA in a group of patient curatively resected for NASH-related HCC with a group of HCV-related HCC.
