Active clinical trials for "Neoplasms"

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

To investigate the relationship between arsenic methylation enzymes (AS3MT, PNP,GSTO1, and GSTO2) genetic polymorphism and UC risk. To explore the relationship between cigarettes metabolites (NNK, NNAL, HBA, NNAL-Gluc, O6-Methylguanine, and N7-Methylguanine) and UC risk. To examine the relationship between cigarette metabolic enzymes (CYP2A6, CYP2A13, and UGT2B7) genetic polymorphism and UC risk. To elucidate the relationship between DNA repair enzymes (MGMT, XPD, XRCC1, and XRCC3) gene polymorphism and 8-OHdG or between DNA repair enzymes and UC risk. To examine relationship between COX-2 (-1195G/A、-765G/C 和8473C/T), IL-6, IL-8, and TNF-α gene polymorphism and 8-OHdG or between COX-2, IL-6, IL-8, and TNF-α gene polymorphism and UC risk. To examine the risk factors of the environment-environment, gene-environment, and gene-gene interaction on the risk of UC.

The purpose of this study is to assess the clinical anti-proliferative activity of STI571 (Glivec®, Novartis, Pharma) in patients with HES defined as: Idiopathic Hypereosinophilic Syndrome (secondary HES), defined as a peripheral blood eosinophilia greater than 1,500 cells/µL for longer than 6 months, absence of other apparent aetiologies for eosinophilia and with or without signs and symptoms of organ involvement, irrespective to expression of any of imatinib targets (c-Kit receptor, PDGFR, bcr-abl receptor) on bone marrow cells. Familiar hypereosinophilia defined as a peripheral blood eosinophilia greater than 1,500 cells/µL for longer than 6 months, absence of other apparent aetiologies for eosinophilia and signs and symptoms of organ involvement, irrespective to expression of any of imatinib targets (c-Kit receptor, PDGFR, bcr-abl receptor) on bone marrow cells, and with a recognized or reported cases of hypereosinophilia in the patient's family. Chronic myeloproliferative disorder, defined as chronic eosinophilic leukemia (CEL) with the presence of blasts (>10%) in the bone marrow (BM), or the presence of immature eosinophils in different tissues, or an aggressive clinical course or the presence of clonal cytogenetic anomalies. Myeloproliferative disorder (MPD) with eosinophilia, eosinophilic leukemia or chronic myelomonocytic leukemia [myeloproliferative disorders/myelodysplastic syndromes (MPD/MDS)] with evidence of: t(5;12)(q33;p13) by cytogenetic or fluorescent in situ hybridization (FISH) analysis, or ETV6/TEL-PDGFRB fusion transcript by reverse transcription polymerase chain reaction (RT-PCR), or PDGFRB disruption, assessed or suspected, by other translocations with additional partner genes (H4, HIP1, CEV14 and Rab5) 5, or MPD/MDS who have constitutive activation of the gene for platelet-derived growth factor receptor beta (PDGFRB) 6 by point mutations

The purpose of this study is to determine whether cylindrical abdominoperineal resection is effective in the treatment of advanced very low rectal cancer

To determine the association between LVD and clinico-pathologic variables in archived colorectal cancer and Nasopharyngeal carcinoma specimens To determine the association between VEGF-C,-D expression with COX-2 expression and clinico-pathologic variables in colorectal cancer and Nasopharyngeal carcinoma To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma Lymphangiogenesis and factors modulating lymphangiogenesis are associated with clinico-pathological outcome in Nasopharyngeal carcinoma and colorectal cancer. Celecoxib down-regulates lymphangiogenesis Archival colorectal cancer and Nasopharyngeal carcinoma tumor specimens will be obtained from the Department of Pathology. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma, the investigators intend to analyze archived specimens collected in a previously conducted study. Colorectal tumor and nodal specimens and Nasopharyngeal carcinoma primary will be examined for MVD, LVD and growth factor expression using established haematoxylin and eosin and immunohistochemical techniques. Quantification of LVD and MVD shall be performed by two pathologists blinded to clinico-pathological variables using standardised methods.

The purpose of this study is to evaluate the incidence of postthoracotomy pain between total intravenous anesthesia (TIVA)and inhalation anesthesia after lung surgery.

RATIONALE: Collecting and storing samples of tumor tissue from patients with soft tissue sarcoma to test in the laboratory may help the study of cancer in the future. PURPOSE: This laboratory is collecting tissue samples from patients with soft tissue sarcoma of the arms, hands, legs, or feet treated on clinical trial CRUK-VORTEX.

RATIONALE: Studying Pap smears in the laboratory from women with atypical glandular cells of unspecified significance may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at Pap smears from women enrolled on clinical trial GOG-171.

The purpose of our study is to evaluate the diagnostic validity of a new immunofecal occult blood test (IFOBT) (Teco Diagnostics) in U.S. veterans and to compare it with the guaiac based FOBT.

To investigate the safety of partially matched related human placental-derived stem cells (HPDSC) administered in conjunction with umbilical cord blood (UCB) stem cells from the same donor in subjects with various malignant or nonmalignant disorders potentially curable with stem cell transplantation and to assess potential restoration of normal hematopoiesis and immune function in subjects with these disorders
