Comparing Proton Therapy to Photon Radiation Therapy for Esophageal Cancer
This trial studies how well proton beam radiation therapy compared with intensity modulated photon radiotherapy works in treating patients with stage I-IVA esophageal cancer. Proton beam radiation therapy uses a beam of protons (rather than x-rays) to send radiation inside the body to the tumor without damaging much of the healthy tissue around it. Intensity modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the tumor without damaging much of the healthy tissue around it. It is not yet known whether proton beam therapy or intensity modulated photon radiotherapy will work better in treating patients with esophageal 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.

Pembrolizumab and Chemoradiotherapy for the Treatment of Unresectable Gastroesophageal Cancer
This phase I trial investigates how well pembrolizumab and chemoradiotherapy works in treating patients with gastroesophageal cancer that 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. Chemotherapy drugs, such as fluorouracil, oxaliplatin and docetaxel 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 photons to kill tumor cells and shrink tumors. Giving pembrolizumab together with chemoradiotherapy may help to control gastroesophageal cancer.

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.

Chemoradiation and Pembrolizumab Followed by Pembrolizumab and Lenvatinib Before Surgery for the Treatment of Non-metastatic Esophageal or Esophageal/Gastroesophageal Junction Cancer
This phase II trial studies the effect of chemoradiation and pembrolizumab followed by pembrolizumab and lenvatinib before surgery in treating patients with esophageal or esophageal/gastroesophageal junction cancer that has not spread to other places in the body (non-metastatic). Pembrolizumab is an immunotherapy drug that works by harnessing the immune system to attack cancer. Lenvatinib is an anti-cancer drug that works by stopping or slowing down the growth of cancer cells. Chemotherapy drugs, such as carboplatin and paclitaxel, 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 x-rays to kill tumor cells and shrink tumors. Giving chemoradiation and pembrolizumab followed by pembrolizumab and lenvatinib before surgery may kill more tumor cells.

Testing the Addition of an Anti-cancer Drug, Adavosertib, to Radiation Therapy for Patients With Incurable Esophageal and Gastroesophageal Junction Cancers
This phase I trial investigates the side effects and best dose of adavosertib and how well it works when given in combination with radiation therapy in treating patients with esophageal or gastroesophageal junction cancer for which no treatment is currently available (incurable). Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving adavosertib together with radiation therapy kill more tumor cells than radiation therapy alone in treating patients with esophageal and gastroesophageal junction cancer.

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.
