Active clinical trials for "Adenocarcinoma"

Transrectal ultrasound guided prostate biopsy (TRUS-Bx) is the gold standard method for prostat cancer diagnosis. Cancer detection rate is an important issue in TRUS-Bx. Effective biopsy protocol is necessary to enhance cancer detection rate during the procedure. Patient tolerance may improve the protocol effectiveness and quality. Adequate patient tolerance with optimal local anesthesia may enhance cancer detection rate in TRUS-Bx.

You are invited to participate in a research study to develop new ways to look for abnormal areas/tissues of the esophagus. The current endoscopes used to look at the esophagus are very good, but if the area doesn't look different to the naked eye, then the endoscope can't improve on that. The investigators are looking at using special fluorescent stains in addition to special endoscopes designed to see abnormal areas that are not obvious to the naked eye. Currently specialized microscopes and fluorescent stains are used in clinical laboratories but it takes several days of processing to get results. It may be very helpful to look for areas to sample for abnormal tissue during the endoscopy procedure. You are being asked to let us use "fluorescent peptides" with a special endoscope that allow us to "see" of your esophagus with both fluorescent and white light during your upper GI endoscopy procedure to help target your biopsies. Peptides are small chains of amino acids (the building blocks that make up proteins) linked together. Our peptide is a chain of 7 amino acids attached to a fluorescent dye called FITC (like the one used by your eye doctor). The investigators have prepared special "fluorescent peptides", that will "glow" when a special light is used that should help us separate normal tissue from abnormal tissue. In this study, the investigators will apply the special fluorescent peptides by a spray catheter to your esophagus to help us target you biopsies. Both routine and targeted biopsies will be taken as your endoscopist feels is indicated. This is a phase 1 study. This means that this is the first time the investigators have used this kind of "fluorescent peptide" in people. The Food and Drug Administration (FDA) has not approved this agent, but is allowing us to test it in this study. The main goal of this study is to see if there are any side effects from using the peptide. Our second goal is to see if the peptide "glows" well and if the investigators can take pictures of the areas that do glow. This is the first test of this agent, so it won't be used to change how your biopsies are taken nor how your endoscopy is done.

RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride, 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 an help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of pancreatic cancer by blocking blood flow to the tumor. Giving gemcitabine hydrochloride together with bevacizumab after surgery may kill any remaining tumor cells. PURPOSE: This phase II trial is studying gemcitabine hydrochloride and bevacizumab to see how well they work compared to gemcitabine hydrochloride alone in treating patients who are undergoing surgery for pancreatic cancer.

RATIONALE: Antineoplastons are naturally occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with colon cancer.

RATIONALE: Antineoplastons are naturally occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with stage III or stage IV prostate cancer.

This phase II trial compares copanlisib and olaparib to standard of care chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that did not respond to previous platinum-based chemotherapy (platinum resistant) and that has come back (recurrent). Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Olaparib is a PARP inhibitor. PARP is a protein that helps repair damaged deoxyribonucleic acid (DNA). Blocking PARP may prevent tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving copanlisib and olaparib may extend the time that the cancer does not progress compared to standard of care chemotherapy in patients with recurrent platinum resistant ovarian, fallopian tube, or primary peritoneal cancer.

This pilot study aims to investigate the diagnostic utility of 18F-DCFPyL, a novel low-molecular weight PSMA PET/CT imaging agent, in men with an elevated PSA following radical prostatectomy.

Ductal adenocarcinoma is the most frequent pancreatic solid lesion and the most common tumor of the pancreas. Given its poor prognosis and the major therapeutic consequences, the discrimination between PA and other pancreatic solid lesions is mandatory. EUS is admitted as the most sensitive imaging procedure for the detection and characterization of pancreatic tumors [1-3]. Nevertheless it remains difficult to differentiate, on morphological features, PA from other solid masses. For 15 years, endoscopic ultrasound fine needle aspiration (EUS-FNA) has demonstrated its efficiency for tissue sampling and cyto-histologic diagnosis of PA. However, the negative predictive value (NPV) for the diagnosis of pancreatic adenocarcinoma (PA) remains low (30-70%) in the published prospective series [4]. So, in case of negative result, the choice between surgery and follow-up remains difficult. Additional criteria to get the decision are then warranted. The assessment of pancreatic tumor enhancement using ultrasound contrast agents (UCAs) in real time with imaging specific methods seems useful to improve their characterization [4-8] either by contrast-enhanced EUS (CE-EUS) or, more recently, by contrast-enhanced harmonic EUS (CH-EUS). The aims of this prospective multicenter study is: to compare the NPV of contrast-enhanced endoscopic ultrasound (CH-EUS) and EUS-FNA for the diagnosis of PA; to assess the intra- and inter-observer concordances of CH-EUS for the diagnosis of PA.

The purpose of this study is to establish the safety of Zaltrap in patients who undergo pre-operative chemotherapy with Zaltrap. The investigators hypothesize that Zaltrap my impact colorectal cancer growth and metastasis.

The purpose of this study is to compare the diagnostic gain between 22G standard needle vs 19G Flex needles transduodenal punctures of masses of the pancreatic head.
