Active clinical trials for "Neoplasms"

The purpose of this study is to conduct an analysis of the influences of conventional chemotherapy high-dose chemotherapy followed by autologous stem cell transplant high-dose chemotherapy followed by allogeneic stem cell transplant on the recovery of the immune system. Detailed analysis will help to better understand the pathways of recovery of the immune system following chemotherapy as well as the pathways of recovery of the immune system following autologous or allogeneic stem cell transplantation.

The association between cancer and thrombosis is well known and the occurrence of thrombotic complications is commonly associated with poor prognosis. The aim os this study is to determine the possible value of hypercoagulable parameters as prognostic parameters in advanced non-small cell lung carcinoma (NSCLC).

This study is a prospective, perioperative evaluation of hemodynamic and respiratory parameters in patients undergoing retroperitoneoscopic adrenalectomies.

The primary purpose of the study is to investigate the use of VRI to guide the selection of patients for lung surgery. Perfusion scintigraphy is the current method to assess the fractional contribution of lung function of the remaining lung. The hypothesis is that VRI can determine quantitative postoperative lung function equally accurately as a quantitative perfusion scan.

The Gruppo Italiano Studio Linfomi has been collecting data on patients with Hodgkin Lymphoma (HL) since 1988. This archive represents a homogeneous series of consecutive patients with HL. The very long follow up and the availability of clinical and treatment data make it feasible to perform a study on the gonadal toxicity related to treatment for HL.

The purpose of this study is to determine the survival after laparoscopic colectomies due to carcinoma.

There is a high incidence among the first degree relatives of the carcinoid patients, indicating the involvement of genetic components in its initiation and pathogenesis.

Previous studies have indicated that tumors are warmer than the surrounding tissues. We want to ascertain that this is true for tumors in the GI tract. If so, a thermal camera in an endoscope may aid the diagnosis of tumors. The experiment entails inserting a cannula sheathed thermocouple into the work canal of an endoscope or a colonoscope. The examining physician will bring the distal end to touch the tumors he finds and their adjacent tissues, noting their respective temperatures. This experiment must be conducted before embarking on the complicated and costly project of producing a tiny thermal camera which will be able to navigate the GI tract.

The purpose of this study is to assess the correlation of the predicted post-operative lung function with the observed post-operative lung function (FEV1 and DLCO) in patients who underwent surgical resection (FEV1 = Forced expiratory volume in 1-second. DLCO = Diffusion capacity for carbon monoxide. ppo = predicted postoperative.)and versus the gold standard QRRVP (Quantitative Radionuclide Study of Regional Lung Ventilation and Perfusion)

The purpose of the study is to generate a library of functional imaging and anatomical imaging for patients with head and neck cancers for evaluation of new radiotherapy strategies and planning techniques including IMRT. Secondary aims would be to observe the changes in the cancers as the treatment progresses as well as to define the biologically most active part of the tumor (biological target volume) which could be given more intensive treatment. Tumor volumes seen on different imaging modalities will be compared with a hope of finding an optimal imaging methodology for accurate visualization of the head and neck cancers
