Active clinical trials for "Adenocarcinoma"

The aim of this study is to determine whether para-aortic lymph nodes(No.16) should be included in the lymphadenectomy during the pancreatoduodenectomy in order to improve the long-term survival of patients with pancreatic head ductal adenocarcinoma.

Pancreatic cancer patients at UHN who have had a CT at UHN and have surgery planned will undergo a high resolution ultrasound pre-operatively and intra-operatively. This study is being done to see if using high resolution ultrasound before and during surgery will help the doctors accurately diagnose pancreatic ductal adenocarcinoma and identify if the disease has spread to other areas of the body.

The purpose of this study is to find the highest safe dose of hu5B1-TCO and the best dosing schedule of hu5B1-TCO and 64Cu-Tz-SarAr for finding cancer cells that are CA19-9 positive. This study will also help to find out how much radiation the body is exposed to when 64Cu-Tz-SarAr is used, and provide information on the way the body absorbs, distributes, and gets rid of 64Cu-Tz-SarAr.

The purpose of this study is to find out whether a pre-treatment PET scan using the experimental imaging tracer 18F-FAC can show how much of the standard chemotherapy for PDAC may be taken up by the cancer.

The purpose of the study is to determine the feasibility of using magnetic resonance imaging (MRI)-guided adaptive chemoradiation therapy to improve response to treatment.

The purpose of this study is to see if ultrasound images that are analyzed by a special computer program can be used to measure the size of PDAC tumors in the liver as accurately as CT scans that involve contrast material (also called contrast-enhanced CT scans). All participants in this study will have pancreatic ductal adenocarcinoma (PDAC) that has spread (metastasized) to the liver, and all participants will be scheduled for a routine CT scan that will measure their cancer.

Background: Gastric cancer is a common and serious cancer. Standard treatment is chemotherapy drugs. Researchers want to see if a new treatment helps. It is surgical removal of the cancer and heated chemotherapy delivered to the abdominal cavity called HIPEC. Objective: To test if surgical removal of tumors plus heated intraperitoneal chemotherapy can improve survival in people with gastric cancers. Eligibility: People ages 18 and older with gastric cancer who can have most tumors surgically removed Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Scans Tissue sample from previous surgery Endoscopy with biopsy: A tube with a camera goes through the mouth and into the stomach. It and takes a sample of stomach tissue. Participants might may get medicine to make them drowsy. Laparoscopy: Small cuts are made in the abdomen. A thin tube with a light and camera is inserted into the abdomen. Participants sleep through the procedure. Participants will stay in the hospital. They will have: Surgery to remove as many tumors as possible. HIPEC for 60 minutes: Two thin tubes are put into the abdomen. Two chemotherapy drugs are given through one tube. They are drained out through another at a temperature a few degrees above normal body temperature. Another drug is given in a vein. Recovery for 7-21 days: Participants will have tubes in their stomach and bladder and IVs for a few days. They will get pain medicine, IV fluids, antibiotics, and blood transfusions as needed. Participants will have visits every few months for 3 years, then one a year. Visits include physical exam, blood tests, and scans. They also include dietary assessment and questions.

This phase II trial tests whether 68Ga-FAPI-46 positron emission tomography (PET)/computed tomography (CT) scan works to image cancer-associated fibroblasts (CAFs) in patients with pancreatic ductal adenocarcinoma (PDA) that has not spread to other parts of the body (localized). CAFs are a type of connective tissue cell that are found within or near cancerous tissue. Many CAFs express a protein called fibroblast activation protein (FAP) that are not found on healthy cells in large amounts. 68Ga-FAPI-46 is a radioactive chemical compound designed to circulate through the body and attach itself to FAP on PDA cells. A PET/CT scan is then used to detect the location of FAP lesions. PET scan is a procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. CT scan is a procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination. Giving 68Ga-FAPI-46 PET/CT may help doctors improve upon the diagnosis and management of PDA.

A prospective, opened, multicentric, randomised, phase III trial with two arms: Arm A: curative gastrectomy with D1-D2 lymph node dissection + HIPEC with oxaliplatin Arm B: curative gastrectomy with D1-D2 lymph node dissection Main objective: Compare overall 5-year survival rates in patients surgically treated for advanced gastric adenocarcinoma (T3, T4 and/or N+ and/or with positive peritoneal cytology), treated either with curative gastrectomy and adjuvant HIPEC, or with curative gastrectomy alone.

This clinical trial studies examines a 3D magnetic resonance imaging (MRI) compared to standard MRI imaging techniques in screening patients with prostate cancer. Diagnostic procedures, such as MRI, may help find and diagnose prostate cancer. Computer systems that allow doctors to create a 3-dimensional (3-D) picture of the tumor may help in planning.
