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.

The primary aim of this study is evaluate the impact of hippocampal-sparing prophylactic cranial irradiation (HS-PCI) on survival status in patients with nodal-positive (locally advanced) adenocarcinoma by comparing overall survival rates of patients undergoing HS-PCI to that of patients without this intervention. In addition, this study aims to investigate whether HS-PCI is detrimental on neurocognitive function and to evaluate its impact on the patient's quality of life.

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.

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.

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 compare the diagnostic gain between 22G standard needle vs 19G Flex needles transduodenal punctures of masses of the pancreatic head.

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.
