Active clinical trials for "Adenocarcinoma"

Gastric cancer is a global health issue as the world's fifth most common malignancy and third leading cause of cancer mortality, respectively. Preoperative radiation therapy may improve overall survival (OS) but is seldom used. There is precedent for preoperative chemoradiation, as it is the standard of care for esophageal and gastroesophageal junction tumors. However, reluctance of physicians to prescribe preoperative radiation therapy in gastric cancer may be due to the large treatment fields necessary to account for stomach motion. MR guided radiation therapy (MRgRT) may permit decreased field sizes and more accurate dose delivery. In traditional CT based radiation delivery the same radiation plan is delivered each day without assessment of inter-fraction or intra-fraction motion. MRgRT permits the physician to contour the unique anatomy daily to generate a new plan to account for day to day organ motion. Real-time MR imaging is also used during the treatment so that radiation is only delivered when the tumor is within the pre-specified target area. Thus, MRgRT may overcome traditional barriers of radiation delivery in gastric cancer and improve oncologic outcomes.

A phase II trial to evaluate safety and efficacy of adding durvalumab (MEDI4736) to standard neoadjuvant radiochemotherapy and of adjuvant durvalumab +/- tremelimumab in locally advanced esophageal adenocarcinoma and to evaluate biomarkers predictive for response to immune checkpoint inhibition

The study is being conducted to evaluate the efficacy, safety and tolerability of chemotherapy and apatinib with or without camrelizumab in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma.

This phase II trial studies the side effects of radiation therapy (hypofractionated proton beam therapy or IMRT) for the treatment of prostate cancer that has come back (recurrent) or that has spread to a limited number of sites (oligometastatic) following primary localized treatment. Hypofractionated proton beam radiation therapy delivers smaller doses of radiation therapy over time and may kill more tumor cells and have fewer side effects. IMRT uses high energy x-rays to kill tumor cells and shrink tumors. This trial is being done to find out if a shorter course of radiation therapy is better with fewer side effects for patients with recurrent prostate cancer.

The purpose of this study is to evaluate the safety and clinical activity of nivolumab and relatlimab in patients with metastatic or locally advanced microsatellite stable (MSS) colorectal cancer.

To learn if atezolizumab in combination with oxaliplatin and 5-fluorouracil (5-FU), when given before surgery, can help to control esophageal and/or gastroesophageal cancer. To learn if adding tiragolumab to the above drug combination can help to control the disease.

This pilot and feasibility study studies how well nivolumab and combination chemotherapy work before surgery in treating patients with pancreatic cancer that could possibly be removed by surgery. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body?s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, leucovorin calcium and oxaliplatin, 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 nivolumab in combination with chemotherapy before surgery may work better in treating patients with pancreatic cancer compared to chemotherapy alone.

Gastric cancer (GC) is one of the most common and lethal malignancies in Asia. For early (stage T1) GC, it has been found by analyzing surgical specimens that ~5% of cancers have lymph node metastasis. For patients with stage T2-3N0M0 GCs, there is a considerable probability of micro-metastasis. While the US National Comprehensive Cancer Network (NCCN), the Japanese Gastric Cancer Association (JGCA), and the European Society for Medical Oncology (ESMO) guidelines recommend adjuvant therapy for most patients with resected >T1N0 GCs, the recommendations vary regarding postsurgical treatment for patients with stage T1N+M0 or T2-3N0M0 disease. The JGCA guidelines do not recommend postsurgical chemotherapy for this patient population, while the ESMO support the adjuvant treatment. The NCCN has not offered a definitive recommendation on this issue. Through careful literature search, there is not yet randomized report on whether postsurgical chemotherapy benefits survival for patients with resected T1N+M0 or T2-3N0M0 GC. The first-line chemotherapy regimen for GC is fluorouracil plus platinum. Among fluorouracil, platinum is especially favored due to its less frequent and less severe adverse effects. This large multicenter phase III randomized controlled trial is led by Department of Gastrointestinal Surgery, The First Affiliated Hospital of Anhui Medical University, and carried out in multiple Chinese centers, aiming to compare the safety and efficacy of capecitabine monotherapy versus no therapy in the adjuvant setting for patients with stage T1N+M0 or T2-3N0M0 GC undergoing R0 Resection.

It is a trial to compare the efficacy and safety of Albumin-bound Paclitaxel plus S-1 versus Oxaliplatin plus S-1 (SOX) as first-line treatment in advanced or recurrent gastric adenocarcinoma.
