Active clinical trials for "Neoplasms"

Pancreatic cancer is a disease with an extremely poor prognosis. Such poor results are largely due to a high incidence of local or peritoneal recurrence even after curative R0 resection. If occult microscopic metastasis or residual cancer could be predicted correctly and identify the high risk of peritoneal recurrence, we may have chance to treat these patients by different multimodal locoregional or adjuvant therapy to improve the treatment outcome.

To study the genomics with cell cycle and lymphocyte differentiation in disease, remission and relapse of childhood acute lymphoblastic leukemia. Then correlate these data with age, white cell count, cytogenetic changes, response to the chemotherapy and prognosis.

This study includes two semi-consecutive parts: Part I Open label, controlled, Calibration part aimed to calibrate the CellDetect® device for identifying bladder cancer cells in urine samples. Part II Prospective, controlled, blinded part to determine the performance of the CellDetect® device in monitoring bladder cancer recurrence in patients with a history of TCC, using urine cytology samples The following subjects will be enrolled: Subjects previously diagnosed with bladder cancer undergoing routine cystoscopic surveillance, TURT or Cystectomy.

The purpose of this study is to evaluate the gene expression patterns from colorectal mucosal cells collected through the use of a standard anoscope and cytology brush. Patients will include those scheduled for routine colonoscopy procedures and those with confirmed colorectal cancer.

the principal research objective is to form a database of tissue samples from patients with colorectal (bowel) cancer. The tissue samples that will be used for this research will have already been taken for diagnostic or therapeutic reasons. We will also be asking for consent for a research blood sample. The database will be used to improve our understanding of the molecular genetics and gene expression patterns in colorectal cancer.

The purpose of this project is to analyze tumour tissue from a group of subjects with malignant melanoma, who have been treated at the Royal Marsden Hospital.

Two major genetic pathways leading to colorectal carcinoma can well be distinguished; the 'suppressor pathway', which is characterized by inactivation of tumor-suppressor genes and the 'mutator pathway', which is characterized by microsatellite instability. The purpose of this study is to explore a third putative pathway; microsatellite and chromosome stable colorectal cancer where an alternative cancer-causative mechanism might play a role.

The purpose of our study is to determine whether contrast-enhanced dynamic MRI (DCE MRI) analysis of tumor angiogenesis and perfusion can be used as a reliable modality to differentiate benign from malignant solitary pulmonary nodules (SPN) before surgical intervention, using kinetic model derived from DCE MRI, and further correlate if there is any positive correlation between angiogenesis factor (vascular endothelial growth factor VEGF, microvessel density MVD); and if the perfusion parameters from DCE MRI can predict patients' outcomes and survival.

Hepatocellular carcinoma (HCC) is one the most common malignancies in the world, especially in sub-Saharan Africa and Southeast Asia. Since 1984, it has been the leading cause of cancer death in Taiwan. About 6000-8000 people died of this cancer every year in Taiwan. DNA microarray (DNA chip) is a very powerful tool to clarify the genetic changes in cancers. Expression profiling techniques have been used to simultaneously monitor the expression of thousands of genes from human tumor samples. It has been successfully used to predict clinical outcome and survival as well as classify different types of cancer. In this study, we will use the DNA chip to study the genetics in liver cancer patients.
