Studying the PAGODA Algorithm for Chemotherapy Dose Changes to Prevent Unplanned Treatment Delays
This study seeks to learn whether using the PAGODA algorithm to guide chemotherapy dosing will lower the chance of unplanned delays during chemotherapy for cancer in the gastrointestinal system compared to usual care.

Perioperative Telemonitoring to Optimize Cancer Care and Outcomes
This study aims to see whether an at-home monitoring program that collects health, symptoms, and quality of life data in real-time can be included as part of the care of surgery patients in order to provide better recovery. Patient-generated health data (weight, temperature, oxygen level, heart rate, blood pressure, daily steps, symptoms, quality of life) using at-home monitoring devices (thermometer, a pulse oximeter, a digital scale and a Vivofit 4 watch) and smart device applications are used more and more to measure value and quality in cancer care. However, measuring patient-generated health data is not currently part of standard care following cancer surgery. An at-home monitoring program may improve the care of patients after hospital discharge from surgery and may help reduce complications by identifying issues early.

Vasodilator Therapy With Isosorbide Mononitrate or Diltiazem to Reduce Vasotoxicity in Patients With Gastrointestinal Cancer Receiving Fluoropyrimidine Therapy
This phase I/II trial compares the effect of drugs that causes widening of blood vessels as a result of smooth muscle relaxation (vasodilator therapy) with isosorbide mononitrate, diltiazem or placebo to reduce vasotoxicity in patients with gastrointestinal cancer receiving fluoropyrimidine therapy. Some patients develop chest pain (possibly even a heart attack, a drop in heart function, or a rhythm abnormality) during treatment with a class of cancer drugs known as fluoropyrimidines, which include 5-Fluorouracil (5-FU) and capecitabine. These side effects are believed to be due to the development of an abnormal reactivity of the blood vessels referred to as vasospasm. Vasotoxicity is damage or toxicity inflicted upon blood vessels (vascular system), often causing dysfunction, remodeling, or narrowing (vasoconstriction). It is a broad term used to describe the detrimental effects of certain agents, such as chemotherapy drugs. Researchers want to evaluate how often the reactivity of blood vessels becomes abnormal, during the treatment with 5-FU or capecitabine and how clinically relevant and controllable/preventable this phenomenon is in patients with gastrointestinal cancer.

Massage Therapy in Reducing Chemotherapy-Induced Peripheral Neuropathy in Patients With Gastrointestinal or Breast Malignancies
This clinical trial studies massage therapy in reducing chemotherapy-induced nerve problems (peripheral neuropathy) that may cause pain, numbness, tingling, swelling, or muscle weakness in different parts of the body in patients with gastrointestinal or breast malignancies. Massage therapy may help reduce chemotherapy-induced peripheral neuropathy symptoms and improve quality of life.

Fucoidan for Preventing Chemotherapy-Related Fatigue in Patients With Gastrointestinal or Gynecological Cancer
This clinical trial tests how well fucoidan works in preventing chemotherapy-related fatigue compared to a placebo in patients with gastrointestinal (GI) or gynecological (GYN) cancer. Fatigue poses a burden in patients with malignancies undergoing systemic chemotherapy. Fucoidan is a dietary supplement made of complex sugar that contain sulfate groups attached to their sugar units (sulfated polysaccharide) which found in brown seaweed. It is thought to have anti-inflammatory, anti-viral, anti-thrombotic, anti-diabetic, and anti-tumor effects in pre-clinical models. Giving fucoidan may be effective in preventing chemotherapy-related fatigue in patients with GI or GYN.

Evaluation of Portal Vein Stenting in Patients With Portal Vein Stenosis and Gastrointestinal Cancers
This study collects information about the safety and effect of portal vein stenting in gastrointestinal cancer patients with portal vein stenosis. This study may help researchers learn how long the portal vein stays open and free from blockage and the effects of portal vein stenting on patients' overall well-being.

Data Collection for the Assessment of Acute and Late Normal Tissue in Patients Treated With Proton Therapy
This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy.

2 Versus 6 Hour Oxaliplatin Infusions in Patients With Gastrointestinal Cancers
This phase II trial studies how well giving oxaliplatin over 6 hours works in treating nerve damage in patients with gastrointestinal cancers. Oxaliplatin can cause side effects such as nerve damage that may delay or reduce the dose of oxaliplatin. Giving oxaliplatin over a longer period of time (6 hours) may prevent or delay the development of nerve damage, which may keep patients on standard doses of chemotherapy longer, without having to delay treatment.

Thermal Ablation and Spine Stereotactic Radiosurgery in Treating Patients With Spine Metastases at Risk for Compressing the Spinal Cord
This phase II clinical trial studies how well thermal ablation and spine stereotactic radiosurgery work in treating patients with cancer that has spread to the spine (spine metastases) and is at risk for compressing the spinal cord. Thermal ablation uses a laser to heat tumor tissue and helps to shrink the tumor by destroying tumor cells. Stereotactic radiosurgery delivers a large dose of radiation in a short time precisely to the tumor, sparing healthy surrounding tissue. Combining thermal ablation with stereotactic radiosurgery may be a better way to control cancer that has spread to the spine and is at risk for compressing the spinal cord.

Molecular Epidemiology of Biliary Tree Cancers
This study is to learn if certain risk factors (environmental, viral, behavioral, medical, and dietary), tumor markers, and genetic changes can predict the development and outcome of biliary tree cancers. Establishing biomarkers models from patients may help doctors to further understand how biliary tree cancer is affected by different treatments, and why some people's cancer responds differently than others.

A Vaccine (Ad5.F35-hGCC-PADRE) for the Treatment of Gastrointestinal Adenocarcinoma
This phase IIA trial investigates the side effects of Ad5.F35-hGCC-PADRE vaccine and to see how well it works in treating patients with gastrointestinal adenocarcinoma. Ad5.F35-hGCC-PADRE vaccine may help to train the patient's own immune system to identify and kill tumor cells and prevent it from coming back.
