Serum Concentration of Lidocaine After Local Injection During Mohs Micrographic Surgery
Basal Cell CarcinomaSquamous Cell CarcinomaThe 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.
Indocyanine Green and Portal Pressure in Viral and Alcoholic Cirrhotic Patients With Hepatocarcinoma...
CarcinomaHepatocellular3 moreThe 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.
B-Receptor Signaling in Cardiomyopathy
CarcinomasAmyloidosis37 moreWe hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.
VEGF Imaging in Renal Cell Carcinoma
Renal Cell CarcinomaThe 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.
Correlation Between Skin Carotenoid Levels and Previous History of Skin Cancer
Skin CancerBasal Cell Carcinoma1 moreThe 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 Effects of Upper Airway and Digestive Tract Tumors on the Immune System
Esophageal NeoplasmHead and Neck Neoplasm3 moreThe 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.
Combining PET/CT and EBV DNA to Evaluate the Hazard of Progression in the Follow-up of Locally Advanced...
Nasopharyngeal CarcinomaPET/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.

Plasma EBV DNA Monitoring in Post-treatment NPC Patients
Nasopharyngeal CarcinomaNPC2 moreContinuous regular monitoring of plasma EBV DNA in nasopharyngeal carcinoma (NPC) after treatment have rarely been investigated. The investigators try to analyze the long-term observational results (role in early relapse detection and impact on survival) in NPC patients after curative treatment.
