The purpose of the study is to evaluate the ability and efficacy of using a polarization-enhanced reflectance and fluorescence imaging device, PERFIS, (see the Device Brochure) for demarcation of nonmelanoma skin cancer margins prior to surgery. PERFIS is a harmless and non-invasive device that has been used to image biological tissue both in vitro and in vivo. In this study it will be used to image nonmelanoma skin cancer lesions prior to surgery. The use of PERFIS will not affect patient care or treatment decisions in any way. No extra tissue will be used for imaging.
The purpose of this study is to determine whether the combination of paclitaxel, capecitabine, mitomycin and intensity-modulated radiotherapy is more effective than the standard combination of capecitabine, mitomycin and intensity-modulated radiotherapy (IMRT) in patients with squamous-cell anal cancer.
Nasopharyngeal carcinoma (NPC) is a geographically endemic, Epstein-Barr virus (EBV)-associated carcinoma of epidermoid origin. It occurs most commonly in Southern China and Southeast Asia. The NPC cells are poorly differentiated or undifferentiated with a high incidence of lymphatic and hematological dissemination. Because of the inherent anatomic constraints and a high degree of radiosensitivity, radiotherapy (RT) has been the primary treatment for NPC patients. NPC is also a chemosensitive tumor. Various modes of combined chemoradiotherapy have been used to treat NPC patients with advanced-stage diseases during recent 20 years. However, treatment outcome for locoregionally advanced NPC is still unsatisfactory.
Nasopharyngeal carcinoma (NPC) differs from other head and neck malignancies in terms of its epidemiology, pathology, and treatment outcome . It is endemic in China and is one of the major public health problems. Concurrent radiotherapy and chemotherapy is the primary treatment for patients with NPC. Despite such aggressive treatment, many patients with locally advanced NPC still develop locally recurrent disease. Since local control is directly related to patient morbidity and mortality in NPC, there is a strong need to identify methods to further improve treatment outcome for NPC. One strategy to improve local control is to escalate the dose of radiotherapy. This is because local control has been shown to be directly related to the radiotherapy dose. Several different techniques, including brachytherapy, stereotactic radiosurgery, and dose-painting intensity modulated radiotherapy (IMRT), have been used to increase radiotherapy dose. However, due to the large number of critical anatomic structures near the nasopharynx, dose-escalation in NPC can also lead to increased toxicities. One technique that has achieved dose-escalation with minimal increase in toxicity is simultaneous modulated accelerated radiation therapy (SMART). The main challenge for such treatment is to identify the appropriate tumor volume to receive the high-dose radiotherapy. Conventional dose-escalation is conducted using computed tomography (CT) to identify the gross tumor volume (GTV). However, recent progress with F-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in treatment planning allows more accurate tumor volume delineation. We hypothesize that the use of PET/CT in treatment planning can improve dose-escalation radiotherapy for NPC which in turn can improve therapeutic efficacy while reducing toxicity. PET/CT imaging of tissue hypoxia using [F-18]fluoromisonidazole (FMISO), the most widely used nitroimidazole imaging agent.Given that there has been no clinical trials directly comparing conventional chemoradiotherapy to CT-guided dose-escalation chemoradiotherapy or PET/CT guided dose-escalation chemoradiotherapy in locally advanced NPC.This was a study to evaluate the role of FMISO-PET hypoxia imaging for predicting survival in NPC,our study aims to compare the local control, overall survival and toxicities of the three treatment regimens..
Oral cancer represents the sixth most common cancer worldwide whilst in Pakistan it ranks the second most common cancer in either gender. Histologically, over 90% of oral cancer lesions are squamous cell carcinomas which are diagnosed on the basis of histopathological analysis. However, proliferation kinetics and nucleolar status are not clearly delineated by routine H&E examination; thus making use of various proliferation markers imperative for the purpose. Nuclear organizer regions (AgNORs) are associated with proliferative activity and represents as a diagnostic aid in oral malignancies. Similarly, methyl green pyronin (MGP) stain has also been valuable as a complement in routine histopathological studies of several neoplastic entities. Morphometric techniques offer an opportunity to quantify nuclear changes associated with malignancy and may provide an objective basis for grading the tumors. The present study is planned to analyze the morphometric parameters of the MGP stain in oral squamous cell carcinoma, and in their various histological grades, and to assess if the MGP staining parameters could give information on the aggressiveness of the malignant lesions of oral cavity. Sections from thirty cases of squamous cell carcinoma along with thirty cases of normal oral mucosa will be evaluated for methyl green pyronin (MGP) and AgNOR staining. Morphometric analysis of various MGP staining and AgNOR parameters would be performed using micrometer. Statistical analysis of the results will be carried out using SPSS. Quantitative variables will be expressed as mean ± Standard Deviation. Frequencies and percentages will be given for qualitative variables. It is hypothesized that oral squamous cell carcinoma will exhibit significantly higher MGP staining and AgNOR staining parameters than normal mucosa of the oral cavity.
The purpose of this study is to determine whether compared with arsenic trioxide TACE alone, arsenic trioxide TACE and intravenous administration could further prolong the overall survival.
This study is conducted in the United States of America (USA). The aim of the study is to monitor the number of annual new adult cases of medullary thyroid carcinoma (MTC) and to establish a registry for these new cases in order to identify any possible increase related to the introduction of liraglutide, exenatide once-weekly, and other GLP-1 receptor agonists into the US market.
This is a randomized, double-blinded, placebo-controlled, multi-center Clinical Trial. Patients with no tumor lesions one month after resection of hepatocellular carcinoma will be randomized in a 1:1 ratio to 1 of the 2 treatment groups：6mg/d Tyroserleutide (injection), or placebo. The objective is to evaluate the effect of Injectable Tyroserleutide on the recurrence-free survival,overall survival,quality of life,and the safety and tolerability of subjects after the resection of hepatocellular carcinoma
A research study to learn about the biologic features of cancer development, growth, and spread. We are studying components of blood, tumor tissue, normal tissue, and other fluids, such as urine, cerebrospinal fluid, abdominal or chest fluid in patients with cancer. Our analyses of blood, tissue, and/or fluids may lead to improved diagnosis and treatment of cancer by the identification of markers that predict clinical outcome, markers that predict response to specific therapies, and the identification of targets for new therapies.
