Active clinical trials for "Neoplasms"

High risk papillomavirus (HR-HPV) have an oncogenic role in Oropharyngeal squamous cell carcinomas (OP-SCC) in at least 25% of the cases and the prevalence is increasing. HPV+ might be more chemo and radio sensible with a better prognosis (disease-free survival (DFS) and overall survival (OS) as compared to HPV negative OP-SCC ; hypothesis : 2y DFS > 20% improvement). The principal objective is to determine the impact of the status of HR-HPV in the prognosis of the OP-SCC. The principal criteria is the 2-years DFS. Secondary objective : virologic characteristics of HPV+ tumors.

RATIONALE: Gathering information over time from follow-up visits may help doctors plan the best follow-up schedule. It is not yet known which follow-up schedule is more effective in improving patient quality of life. PURPOSE: This randomized clinical trial is comparing follow-up schedules to see how well they work in patients with newly diagnosed stage IB or stage II melanoma.

RATIONALE: Gathering information about vitamin D supplementation and sun exposure in patients with melanoma may help doctors learn more about the disease and find what may affect cancer relapse. PURPOSE: This clinical trial is studying vitamin D supplementation and sun exposure in patients who have undergone surgery for stage IB, stage II, or stage IIIA melanoma.

The purpose of this study is to establish a Brain and Spinal Tumor Tissue/Specimen repository to serve as a resource for current and future scientific studies.

The technique of sentinel lymph node mapping in patients with colon cancer varies among reports, and the optimal method remain to be established. The purpose of this study was to determine the optimal injection technique for sentinel lymph node mapping for colon cancer.

Non-small cell lung cancer (NSCLC) has a poor prognosis if not caught early enough. One of the factors that may impact the ability to control NSCLC is low oxygen levels (hypoxia) inside the tumour. This study will use 18F-FAZA PET scans to assess whether patients have hypoxic tumours and to monitor the changes to the hypoxic areas of a tumour during currently available standard treatment. It is hypothesized that 18F-FAZA PET may predict response to treatment, local control, and/or survival in NSCLC.

The purpose of this study is to determine whether monitoring of levels of Serological Markers ProGRP, CgA, NSE and Pyruvate Kinase M2 are effective in the Evaluation of Diagnosis, Monitoring Therapeutic Effects and Predicting response to somatostatin analogues in Patients with Malignant Neuroendocrine Tumors.

Knowledge of the impact of gene expression profiling could allow optimisation of chemotherapy regimens for individual patients. It could ensure that patients do not receive a particular form of chemotherapy if it is unlikely to benefit them, and in these circumstances an alternative form of chemotherapy that may prove beneficial could be selected. This information will therefore allow chemotherapy to be tailored to the individual tumour. It may help identify those patients with a poorer prognosis who could be selected for further therapy post surgery or a different treatment strategy at the outset.

Newly diagnosed pediatric patients (age < 19 years) with bcr-abl-positive CML will be treated with imatinib. Serial monitoring of treatment response is performed in one month intervals during the first three months of treatment and in three months intervals thereafter. Patients with non-response, poor response (either molecular, cytogenetic, or hematologic non-/poor response) or progress of the disease while under imatinib treatment will stop imatinib and undergo stem cell transplantation. All responders to imatinib treatment with an HLA matched donor will undergo stem cell transplantation not later than 2 years after diagnosis.

RATIONALE: Learning about long-term effects in patients with testicular cancer may help doctors plan better treatment and follow-up care. PURPOSE: This clinical trial is using CT scans to follow patients who have been treated for metastatic testicular cancer.
