Active clinical trials for "Carcinoma"

Two Phase Ⅲ trials (TAX323 and TAX324) showed induction chemotherapy adding docetaxel to cisplatin plus fluorouracil (TPF) could significant improve survival in head and neck cancer, and a Phase Ⅱ trial from Hong Kong by Hui and colleges with this strategy has also been reported in nasopharyngeal carcinoma (NPC). However, whether three cycles induction could delay the whole time of treatment and reduce the survival benefit are still unknown. A retrospective study of one cycle TPF induction chemotherapy by the investigators group (not yet published) could improve survival in NPC. It encourage us to conduct this clinical trial.

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.

Hepatocellular carcinoma (HCC) is one of ten leading cancer types worldwide and also in Asia, but the five-year relative survival rate is relatively quite low1-3. As a common complication of HCC, portal vein tumor thrombosis (PVTT) have been reported with an occurrence of 34% ~ 50% in advanced HCC and it is now become an extremely pressing problem for hepatic surgeon. Nevertheless, the patients overall survival (OS) varies on their clinical features or liver function4. For HCC PVTT treatment, current options are surgical resection, embolization chemotherapy, radiation therapy, a variety of ablation therapy, biological and gene therapy,etc. Among them, the use of radiation therapy is getting more and more attention, and it is changing from the past palliative treatment to current curable treatment. From an oncologic point of view, a narrow margin <1 cm is not safe and is often associated with higher rates of recurrence and shorter patient survival.On the other hand, it is also believed that most intrahepatic recurrences arise from multicentric carcinogenesis and are distant from the resection margin.To address this issue, the investigators are going to conduct a series of retrospective and prospective studies to investigate the effect of adjuvant RT for centrally located HCC after narrow margin (<1 cm) hepatectomy on tumor recurrence.

18F-FluoroethylCholine (18F-FECH) is a new tracer used in PET synthesized by Nuclear Medical Center of Peking Union Medical College Hospital and is favored for diagnosis of primary brain tumor. Although 18F-FECH showed a high presence of biological distribution in liver, 18F-FECH PET may have a higher sensitivity in diagnosis of intra- and extra-hepatic lesions of HCC respectively than those of 18F-FDG or 11C-acetate PET scan, and 18F-FECH PET could be a promising tool in diagnosis and staging, therapy selection and prognostic evaluation for HCC patients. However, much more cases are required to verify this theory. The purpose for this study is to establish the model of clinical experimental prospective study, and to evaluate the sensitivity, specificity and accuracy of 18F-FECH PET in diagnosis of HCC.

Hepatocellular carcinoma (HCC) is a common cause of cancer mortality in Asia. Most patients were presented with advanced disease. Percutaneous ethanol injection, radiofrequency ablation, and transcatheter arterial chemoembolization (TACE) are not considered as a curative treatment and have achieved very limited success in eradicating large HCC or tumors causing portal vein thrombosis. With the development of novel radiotherapy (RT) technique, RT can be safely given to patients with larger tumor or portal vein thrombosis. However, RT could achieve a tumor response rate of approximately 50 %. Currently, there was a paucity of studies regarding a quantitative biomarker to predict tumor response or forecast the outcome in advance. To optimize the therapeutic index, there is a need to seek effective biomarkers for personal medicine because pretreatment AFP is not always useful as a surrogate marker in some of the patients. The present study is to investigate whether circulating tumor cell genome in peripheral blood can be used to predict RT response in HCC. We will use the blood sample from patients with locally advanced HCC receiving RT. By using next generation sequencing, We are going to explore the quantity and quality changes of DNAs and RNAs in the patient's serum or plasma. By this way, genomic expression in peripheral blood may play a key role in determining the optimal therapeutic strategies for HCC patients by predicting tumor response to RT.

It is generally estimated that 5 % of patients with thyroid cancer will develop distant metastases, and most of them had an advanced stage of the disease at presentation. Thirty per cent of them are resistant to radio iodine therapy and are called "refractory". Their long term survival is estimated to be less than 10 %. The objective of this study is to identify the factors associated with poor outcome in a cohort of patients with advanced thyroid cancer followed during 5 years. Anaplastic and medullary thyroid carcinomas were excluded.

The purpose of this study is to determine the effect of polymorphisms in the IL-1 gene complex on the development of chronic hepatitis and hepatocellular carcinoma.

The purpose of this research is to investigate school response to families who have children with cancer. It is anticipated that the results of this study will enhance the support that schools can give to the population of families who have a child with cancer. The study will involve the parents in these families, the principal and an educator in the school of the child with cancer. Measurement tools will include surveys, interviews, and other relevant educational and medical documents.

T Cell Receptor-engineered T-cell therapy (TCR T-cell therapy) offers a potentially transformative approach to treating cancer, but is currently limited by the lack of known targets (Maus and June, 2016; Ping et al., 2018). Arguably the most clinically meaningful way to discover new targets and TCRs for TCR T-cell therapy is to study the tumorinfiltrating lymphocytes of patients that are actively responding to immune checkpoint inhibitor (ICI) therapy. These T cells are clonally expanded as a result of checkpoint inhibition and are responsible for the patient's clinical response. The goal of this study is to acquire tumor and blood samples from up to 40 patients with renal cell carcinoma (RCC) malignancies who respond to ICI therapy. T cells will be isolated from these samples and the targets of their TCRs determined using TScan's genome-wide, high-throughput target ID technology. The expected outcome of this study is the discovery of a collection of new targets for TCR T-cell therapy, along with associated TCRs that will then be developed as novel therapies for patients with similar malignancies.

This study seeks to correlate microbial sequencing data from a punch biopsy in patients with skin cancer both melanoma and non-melanoma.
