Filter by:Positron Emission Tomography (PET) is a Nuclear Medicine procedure that uses positron emitting radiolabeled tracer molecules to visualize biological activity. The presence of hypoxia (low oxygen) is associated with poor prognosis in a variety of tumour types and treatment strategies targeting hypoxic cells have been developed. The PET tracer [18]F-FAZA can identify hypoxic areas, and changes in uptake during treatment may predict tumour response.
The value of fusion of functional and anatomical data has been described using several fusion techniques for various nuclear medicine procedures and morphologic imaging modalities (SPECT-CT, SPECT-MRI, Coincidence-CT). We hypothesize that NM -CT data has advantages over the data obtained using separately performed NM study and conventional anatomic imaging as CT. We hypothesize that more accurate localization of the radio-isotope activity on NM images will improve diagnostic accuracy and will have an impact on patient management: Improved accuracy of NM study will improve tumor localization, the evaluation of the extent of disease and the post therapy follow up. It will direct other diagnostic procedures to lesions otherwise undetected, or exclude the need for more invasive procedures. It can also guide invasive procedures and radiation-therapy planning, thus improving therapy results and avoiding unnecessary treatment-related side effects.
RATIONALE: Vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by stopping blood flow to the tumor. Octreotide may help control symptoms, such as diarrhea, caused by the tumor. Giving vatalanib together with octreotide may be an effective treatment for neuroendocrine tumors. PURPOSE: This phase II trial is studying how well giving vatalanib together with octreotide works in treating patients with progressive neuroendocrine tumors.
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of neuroendocrine tumors by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects of giving combination chemotherapy together with bevacizumab and to see how well it works in treating patients with advanced neuroendocrine tumors.
This is a research study looking at the effect of 5-Hydroxy Tryptophan (5-HTP) on urine excretion of 5-Hydroxyindolacetic acid (5-HIAA). 5-HTP is a common over the counter product that is sold in natural food stores and via the Internet. Increased levels of 5-HIAA in the urine can be found in a specific type of cancer, called carcinoid tumor. This study will examine the effect of oral 5-HTP intake on 5-HIAA excretion. Understanding this effect may help to determine which tests should be done in a patient with increased 5-HIAA excretion who's also taking 5-HTP.
Placebo-controlled prospective randomized phase III study to investigate the antiproliferative effect of octreotide in patients with metastasized neuroendocrine tumors of the midgut
The purpose of this study is to find out what effects, good or bad, that thalidomide and temodar have on patients with neuroendocrine tumors.
The purpose of this study is to determine what effects (good and bad) bevacizumab and temozolomide have on patients with neuroendocrine tumors.
This phase II trial is studying how well sorafenib tosylate works in treating patients with progressive metastatic neuroendocrine tumors. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
This phase II trial is studying how well CCI-779 works in treating patients with progressive metastatic neuroendocrine tumors. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop tumor cells from dividing so they stop growing or die.
