Active clinical trials for "Neoplasms"

This prospective observational study will evaluate the evolution of lung cancer related symptoms and their correlation with the disease control rate (complete response, partial response and stable disease) in patients with non-small cell lung cancer initiating first-line treatment with standard platinum-based chemotherapy with or without Avastin (bevacizumab). Data will be collected from each patient at baseline and after 4-6 cycles of chemotherapy.

The study aims to: Achieve molecular imaging of EGFR in patients with colorectal neoplasia in vivo using confocal laser endomicroscopy. Compare the results of in vivo EGFR-specific molecular imaging with CLE and ex vivo immunohistochemistry .

This is a compassionate use protocol to allow palliative therapy for patients with malignant pheochromocytoma and paragangliomas.

The aim of this study is to recruit 50 rectal cancer patients planned to receive standard radiochemotherapy. A baseline ultrasonic elastography is performed prior to radiochemotherapy and followed by re-scans two and six weeks after initiation of treatment. The objective quantitative elastography findings are compared with the TRG score. The purpose is to elucidate ultrasonic elastography's ability to predict treatment response at an early stage by comparing quantitative ultrasound parameters before, during and after treatment with MR scan results and histopathological Tumor Regression Grade (TRG score) after operation.

This is a compassionate use protocol to allow patients with advanced neuroblastoma palliative access to 131I-metaiodobenzylguanidine (131I-MIBG).

Compassionate use of orphan drug 3,4-Diaminopyridine(DAP) in Treatment of Lambert Eaton Myasthenic Syndrome (LEMS). 3,4-DAP is used to decrease the muscle weakness associated with LEMS and hopefully will decrease the need for prednisone and all other therapies that were previously required to control symptoms. How long a patient will take 3,4 DAP depends upon if he/she is seeing benefits from the medication or experiencing side effects that will prevent them from continuation in the study.

Lambert Eaton Myasthenic Syndrome (LEMS) is rare neurological disorder that results in muscle weakness and limited reflex activity. More than half of LEMS cases are associated with a malignancy, usually small cell lung cancer, and tend to progress more quickly than cases not coupled with malignant cells. 3,4diaminopyridine (3,4DAP)is a drug that has been demonstrated to be effective in treating the weakness associated with LEMS as it increases strength and improves autonomic symptoms in LEMS patients. It is not currently approved by the FDA for use in the United States. The investigators plan to use 3,4DAP to treat patients with LEMS here at the Columbia University MDA/ALS Research Center.

The primary objective of this study is to substantiate prediction accuracy(with a tighter 95% confidence interval compared to current diagnostic modalities), of a lung cancer biomarker for risk stratification of patients into high and low risk categories to aid in clinical evaluation of the patient.

The purpose of this study is to determine whether green tea extract is safe for extensive-stage small lung cancer who achieved objective tumor response after first-line therapy.

To take charge of the treatment in rare adult ovarian tumors with an homogenous manner (germinal and sexual cords tumors), at different stages of the disease.
