Active clinical trials for "Carcinoma"

This study aim to investigate Changes in tumor tissue and serum biomarkers before and after cetuximab combined with preoperative radiotherapy in locally advanced thoracic middle-lower segment esophageal squamous cell carcinoma.We want to find one or more effective biomarkers to predict and evaluate the patients who will be benefit from cetuximab combined with preoperative radiotherapy.

A higher percentage of radical resection is reported in studies using neoadjuvant chemotherapy followed by surgery versus surgery alone for esophageal cancer. And neoadjuvant chemotherapy may improve overall survival after surgical resection. Nimotuzumab is a humanized monoclonal antibody against epidermal growth factor receptor (EGFR). The concurrent trial is a clinical phase II trial designed to assess the efficacy of the combination of Nimotuzumab administered concurrently with neoadjuvant chemotherapy in patients with resectable Esophageal Squamous Cell Carcinoma, and to further investigate its side-effect and toxicity

Breast cancer is the first cancer in women, the second etiology of death by cancer and the first cause for women between 35 and 55 years. Diagnostic tools and large screening have been realized with positive impact in a recent review with 31% less likely to die of breast cancer over nearly 30 years compared to women who didn't get regular screening mammograms. Diagnostic tools and treatment also are improving continuously. However, for some women, breast cancer diagnosis is difficult, in case of high density breast, breast modifications after surgery… In these cases, breast MRI is currently the best imaging tool, with high sensitivity about 90% but with a lower specificity about 60%, that lead to futile biopsies. Recently, molecular imaging with PET-CT scan with 18FDG has permitted to widely modify cancer treatment. However, PET-CT scan is not a good imaging tool for initial diagnostic of breast tumor because of a lack in spatial resolution about 8mm. So, researchers developed dedicated PET scan for breast, called Positron Emission Mammography. Our project is in this field of view and is named CLEARPEMSONIC. First clinical studies with PEM showed very good performance of this imaging modality for initial evaluation of breast tumors. PEM performance is not affected by breast density, hormonal status. Spatial resolution is less than 3mm. PEM seems complementary with MRI, adding a better specificity value. In the field of CERIMED, ClearPemSonic Project aims to evaluate an new imaging tool which combined PEM scan and ultrasonography. Technologic evaluation was made. Now a feasibility study is the first step for clinical applications. The main objective of this project is to confirm the feasibility of PEM scan with the ClearPEmSonic. Secondary objectives are to compare results with other conventional imaging modalities and MRI. The gold standard will be histology of the breast tumor.

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world. Partial hepatectomy is still considered as the conventional therapy for HCC. Intrahepatic recurrence of HCC after partial hepatectomy is common and was reported to be more than 77% within 5 years after surgery. Repeat hepatectomy is an effective treatment for intrahepatic HCC recurrence, with a 5-year survival rate of 19.4-56%. This is comparable to the survival after initial hepatectomy for HCC. Unfortunately, repeat hepatectomy could be carried out only in a small proportion of patients with HCC recurrence (10.4-31%), either because of the poor functional liver reserve or because of widespread intrahepatic recurrence. In the past two decades, percutaneous radiofrequency ablation (PRFA) has emerged as a new treatment modality and has attracted great interest because of its effectiveness and safety for small HCC (≤ 5.0 cm). Studies using PRFA to treat recurrent HCC after partial hepatectomy reported a 3-year survival rate of 62-68%, which is comparable to those achieved by surgery. PRFA is particularly suitable to treat recurrent HCC after partial hepatectomy because these tumors are usually detected when they are small and PRFA causes the least deterioration of liver function in the patients. To the best of our knowledge, there has been no report published in the medical literature comparing the efficacy of repeat hepatectomy with PRFA for recurrent HCC. The aim of this retrospective study is to compare the outcome of repeat hepatectomy with PRFA for small recurrent HCC after partial hepatectomy.

Given the growing importance of anti-angiogenic therapies in the treatment of metastatic renal carcinoma, it is expected that this trial will establish the preliminary data needed to apply for funding of a larger clinical investigation of the potential role of PET perfusion imaging in management of renal carcinoma, and potentially other cancers.

The purpose of this study is to investigate the effect of two different doses of vitamin D3 (2000 IU vs. 4000 IU) on serum 25-hydroxyvitamin D (25OHD) levels in patients with hepatocellular carcinoma on the liver transplant list. The study will help determine the dose of vitamin D3 that is required for patients with liver cancer to reach a normal level of 25OHD in the blood.

The treatment for Hepatocellular Carcinoma (HCC) with Portal Vein Tumor Thrombosis (PVTT) is still controversial, and there is no universally agreed protocol for its treatment. Transarterial chemoembolization (TACE) has become the most popular palliative treatment for patients with unresectable HCC, and it is no longer considered as a contraindication to HCC with PVTT. Unfortunately, the long term outcomes are generally poor for HCC treated with TACE, especially for HCC with PVTT. HR remains the only therapeutic option that may still offer a chance of cure. With advances in surgical techniques, it has become feasible to remove all gross tumors, including PVTT which has extended to the main portal vein, safely by surgery. This study aimed to evaluate the safety and efficacy of HR as compared with TACE to treat patients with HCC with PVTT. The investigators also aimed to identify patient groups that might benefit more from either treatment with HR or TACE.

This study is for people with cancer of the liver that cannot be completely removed by surgery. This study involves giving the drugs mitomycin-C and cisplatin, into an artery in the liver. Mitomycin-C is a drug that has been approved by the FDA to treat cancer of the stomach and pancreas. Mitomycin-C is a drug that causes cancer cells to die and prevents them from reproducing. Cisplatin is also a drug that has been approved by the FDA. Cisplatin is approved to treat cancer of the testes, ovaries, lung, esophagus, bladder, head and neck. Cisplatin is a drug that prevents cancer cells from reproducing. The purpose of this study is to see how long it takes subjects' tumor(s) to grow after receiving the study drugs. Another purpose of this study is to look at the side effects of this study therapy and how long subjects survive after receiving it. An additional purpose of this study is to see how well we can predict subjects' response to the study therapy, based on blood and tumor tissue tests. These tests will measure the levels of genes (the cell's blueprint) in subjects' tumors and blood. These genes affect how people's bodies react to the cancer drugs.

We have identified insulin-like growth factor binding protein (IGFBP)-3 as an invasion suppressor gene in ovarian endometrioid carcinoma, and showed association with lower cancer migration, invasion and metastasis. Recently, a novel model of ovarian EC formation from endometriosis was reported, and PTEN was found to be a major protein involved. Inactivation of PTEN has been reported in some ovarian EC tumors and methylation was suggested as one of the major epigenetic changes. This tumorigenesis model has lots of similarity to our established invasion model. Therefore, we plan to study the important of PTEN expression in ovarian EC and if inactivation of PTEN and IFGBP-3 is through methylation. Furthermore, by studying the signal transduction pathways using PTEN and IGFBP-3 transfection, we plan to study the mutual interaction between PTEN and IGFBP-3 on the suppression of tumor invasion in ovarian EC.

This is a pilot study of concomitant radiotherapy and thalidomide for patients with locally advanced HCC.Besides toxicity and efficacy, mechanistic studies including dynamic contrast enhanced MRI and serum cytokines will be evaluated.
