Active clinical trials for "Carcinoma"

The purpose of this study is to determine the difference of skin carotenoid levels between subjects with previous squamous cell carcinomas (SCC), subjects with previous basal cell carcinomas (BCC) and a control group.

The aim of the investigators' study is to elucidate the relationship between a functional liver test (e.g., ICG) and the PREOPERATIVE value of portal hypertension in the patients with impaired liver function from alcoholic and non-alcoholic aetiologies. Alcoholic and viral cirrhosis present important differences in terms of cellular mechanisms responsible for the disease progression with a distinct and unique gene expression pattern that regulates the type of inflammatory response. These differences probably influence the hepatic functional reserve and the onset of portal hypertension at a comparable clinical and biological level of derangement and the investigators may expect significant differences in the recovery from hepatectomy. The investigators' hypothesis is that at a comparable ICGR-15 rate non-viral cirrhotic liver presents higher portal pressure values and the investigators also argue that alcoholic cirrhotic patients would tolerate a larger hepatic resection than would viral cirrhotic do.

The primary objective of this study is to (1) determine whether local injection of lidocaine used during Mohs surgery will elevate serum lidocaine concentrations to a level that could cause systemic symptoms and (2) determine whether sustained high levels of serum lidocaine occur after intralesional anesthesia on the face and neck. This study is a cross-sectional study of 10 subjects with basal cell carcinoma or squamous cell carcinoma of the face or neck requiring Mohs micrographic surgery. The study will consist of a brief questionnaire and blood draws during their Moh's surgical procedure.

Green tea is extracted from steam treated leaves, allowing the preservation of catechins, the active elements of the infusion. Catechins are recognized for their anti-cancer activity. Catechins act on the capacity of cancer to disseminate to other organs because of their anti-protease action. Proteases are proteins capable of digesting the cancer environment and facilitating the progression of cancer cells to blood vessels which will bring them to distant organs. We know that ovarian cancer responds well to the initial treatment of chemotherapy but tends to recur rapidly. We intend to provide green tea with higher concentrations of catechins to women with complete remission of their ovarian cancer in an attempt to delay cancer relapse. We also intend to identify, with molecular technologies, the proteases involved in ovarian cancer recurrence and response to catechins. Our objective is to test the hypothesis that green tea intake may delay ovarian cancer recurrence and to develop tools to predict which women will best benefit of the addition of green tea to their initial treatment.

The primary objective of the study is to evaluate the feasibility of 89Zr-bevacizumab PET imaging as a biomarker before and during treatment with sunitinib or bevacizumab plus interferon in patients with RCC. 89Zr-bevacizumab PET imaging will be regarded a promising biomarker if the target for treatment (VEGF) can be visualised and if uptake changes after institution of treatment.

We have compared to types of surgery to assess which one leaves the smaller surgical defect.

The goal of this study is to learn how tumors of the upper airway and digestive passages (tongue, throat, mouth, and voicebox) affect the body's immune defenses and energy storage. Previous studies have shown that tumors of the vocal tract produce signals that could help the tumor escape the body's immune defenses and use the body's energy and mineral stores to grow. Researchers are hoping to learn more about what signals give tumor cells an advantage to live and grow, how tumor cells control these signals, and how these signals affect the rest of the body. This study will look closer at researchers belief that tumors in the vocal tract contain genes (genetic information) that abnormally function to allow the tumors to survive and grow against the attack of the body's normal immune system Patients with cancerous tumors (squamous cell carcinoma) and benign (non-cancerous) tumors (papilloma) of the upper aerodigestive tract who are candidates for standard or investigational therapy are eligible to participate in this study. Tumor cells will be collected from patients participating in the study, who will undergo standard surgical treatment or biopsies for their conditions. Once tumor cells are collected they can be analyzed for their genetic make-up. In addition, patients will undergo several tests using skin, blood, and urine to look closely at the function of their immune systems and metabolism.

PET/CT and EBV DNA are important in diagnosis of NPC. We consider that combining post-treament PET/CT and plasma EBV DNA may be effective in evaluating the hazard of progression in the follow-up of Locally Advanced Nasopharyngeal Carcinoma. Hence we establish this prospective cohort study.

This trial studies comprehensive geriatric and quality of life assessments in older patients with head and neck or lung cancer that has or has not spread to other parts of the body who are undergoing standard surgery or chemoradiation, and their caregivers. Comprehensive geriatric assessment may improve the quality of life of patients with head and neck or lung cancer and their caregivers.

The primary endpoint will be acute toxicity. Secondary endpoints included: late toxicity and quality of life; loco-regional control, disease free survival and overall survival.
