Testing the Addition of Radiotherapy to the Usual Treatment (Chemotherapy) for Patients With Esophageal and Gastric Cancer That Has Spread to a Limited Number of Other Places in the Body

This phase III trial studies how well the addition of radiotherapy to the usual treatment (chemotherapy) works compared to the usual treatment alone in treating patients with esophageal and gastric cancer that has spread to a limited number of other places in the body (oligometastatic disease). Radiotherapy uses high energy x-rays, gamma rays, or protons to kill tumor cells and shrink tumors. Drugs used in usual chemotherapy, such as leucovorin, 5-fluorouracil, oxaliplatin, and capecitabine, 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. Adding radiotherapy to the usual chemotherapy may work better compared to the usual chemotherapy alone in treating patients with esophageal and gastric cancer.

Personalized Neoantigen Peptide-Based Vaccine in Combination With Pembrolizumab for Treatment of Advanced Solid Tumors

This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

Short-Course Chemoradiotherapy Followed by Chemotherapy for the Treatment of Resectable Gastric Adenocarcinoma

This phase Ib trial investigates the side effects and how well a shorter course of chemotherapy and radiation treatment (chemoradiotherapy) for 2 weeks instead of 5 weeks followed by standard chemotherapy works in treating patients with gastric cancer who are scheduled to have treatment and then surgery to remove the tumor. Chemotherapy drugs, such as capecitabine and fluorouracil, 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. Radiation therapy uses high energy sources to kill tumor cells and shrink tumors. Giving short-course chemo-radiotherapy before chemotherapy and surgery may help to control the disease.

Pembrolizumab and Lenvatinib for the Treatment of Advanced, Unresectable, or Metastatic Gastroesophageal Adenocarcinoma

This early phase I trial studies the effect of pembrolizumab and lenvatinib in treating patients with gastroesophageal adenocarcinoma that has spread to other places in the body (advanced/metastatic) or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and lenvatinib may kill more tumor cells.

PIPAC for the Treatment of Peritoneal Carcinomatosis in Patients With Ovarian, Uterine, Appendiceal, Colorectal, or Gastric Cancer

This phase I trial studies the side effects of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in treating patients with ovarian, uterine, appendiceal, stomach (gastric), or colorectal cancer that has spread to the lining of the abdominal cavity (peritoneal carcinomatosis). Chemotherapy drugs, such as cisplatin, doxorubicin, oxaliplatin, leucovorin, fluorouracil, mitomycin, and irinotecan, 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. PIPAC is a minimally invasive procedure that involves the administration of intraperitoneal chemotherapy. The study device consists of a nebulizer (a device that turns liquids into a fine mist), which is connected to a high-pressure injector, and inserted into the abdomen (part of the body that contains the digestive organs) during a laparoscopic procedure (a surgery using small incisions to introduce air and to insert a camera and other instruments in the abdominal cavity for diagnosis and/or to perform routine surgical procedures). Pressurization of the liquid chemotherapy through the study device results in aerosolization (a fine mist or spray) of the chemotherapy intra-abdominally (into the abdomen). Giving chemotherapy through PIPAC may reduce the amount of chemotherapy needed to achieve acceptable drug concentration, and therefore potentially reduces side effects and toxicities.

Testing Immunotherapy (Atezolizumab) With or Without Chemotherapy in Locoregional MSI-H/dMMR Gastric and Gastroesophageal Junction (GEJ) Cancer

This phase II trial compares atezolizumab in combination with chemotherapy (docetaxel, oxaliplatin, leucovorin calcium, fluorouracil, capecitabine) to atezolizumab alone for controlling the growth and/or spreading of the disease in patients with gastric or gastroesophageal junction (JEG) cancer that has not spread from where it first started (local) or only has spread to nearby lymph nodes or tissue (locoregional) and has high microsatellite instability (MSI-H) and mismatch repair deficiency (dMMR). The mismatch repair (MMR) system in the body corrects errors made during the copying of DNA and serves as a proofreading function. If this system isn't working correctly, mutations (changes) in DNA occur which can allow the cancer to grow or spread. This is called dMMR (deficient mismatch repair) . MSI-H describes cancer cells that have a high number of mutations within microsatellites. For example, microsatellite testing that shows mutations in 30% or more microsatellites is called microsatellite instability-high (MSI-H). Microsatellites are short, repeated sequences of DNA. There is evidence that MSI-H/ dMMR gastric or GEJ tumors respond well to immunotherapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. Capecitabine is in a class of medications called antimetabolites. It is taken up by tumor cells and breaks down into fluorouracil, a substance that kills tumor cells. Chemotherapy drugs such as leucovorin calcium and fluorouracil 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. Using atezolizumab as immunotherapy with and following chemotherapy versus atezolizumab alone prior to and after surgery may shrink or stabilize the tumor in patients with MSI-H/dMMR localized gastric or GEJ cancer and may increase the length of time after treatment that cancer does not come back or get worse.

Nivolumab, Ipilimumab and Chemoradiation in Treating Patients With Resectable Gastric Cancer

This pilot phase I/II trial studies the side effects and how well nivolumab and ipilimumab in combination with chemotherapy and radiation therapy work in treating patients with gastric cancer that can be removed by surgery. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, 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 oxaliplatin and fluorouracil, 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. Intensity-modulated radiation therapy uses thin beams of radiation of different strengths aimed at the tumor from many angles. This type of radiation therapy may reduce the damage to healthy tissue near the tumor. Giving nivolumab, ipilimumab, chemotherapy and radiation therapy may work better in treating patients with gastric cancer.

Enhanced Outpatient Symptom Management to Reduce Acute Care Visits Due to Chemotherapy-Related Adverse Events

This clinical trial studies if enhanced outpatient symptom management with telemedicine and remote monitoring can help reduce acute care visit due to chemotherapy-related adverse events. Receiving telemedicine and remote monitoring may help patients have better outcomes (such as fewer avoidable emergency room visits and hospitalizations, better quality of life, fewer symptoms, and fewer treatment delays) than patients who receive usual care.

Ramucirumab and Trifluridine/Tipiracil or Paclitaxel for the Treatment of Patients With Previously Treated Advanced Gastric or Gastroesophageal Junction Cancer

This phase II trial studies the effect of the combination of ramucirumab and trifluridine/tipiracil or paclitaxel in treating patients with previously treated gastric or gastroesophageal junction cancer that has spread to other places in the body (advanced). Ramucirumab may damage tumor cells by targeting new blood vessel formation. Trifluridine/tipiracil is a chemotherapy pill and that may damage tumor cells by damaging their deoxyribonucleic acid (DNA). Paclitaxel may block cell growth by stopping cell division which may kill tumor cells. Giving ramucirumab and trifluridine/tipiracil will not be worse than ramucirumab and paclitaxel in treating gastric or gastroesophageal junction cancer.
