Nutrition Intervention Trials in Linxian Follow-up Study

Two large, nutritional intervention trials were conducted in Linxian, China between 1985-1991. These trials tested the effect of multiple vitamins and minerals in the prevention of esophageal cancer in a population with the highest known rate for this disease in the world. Results from the trials showed that Beta-carotene + Vitamin E + selenium reduced total mortality, total cancer mortality, and stomach cancer incidence and mortality. Multivitamins/minerals also showed reduction in premalignant lesions. Preliminary follow-up data obtained for the time period after cessation of intervention in 1991 suggests that the observed benefit for total and cancer mortality is reduced but that the benefit for stomach cancer remains. The objectives of the follow-up study are: (1) to continue to determine cancer incidence and all causes of mortality in trial participants after intervention to permit examination of potential effects of the interventions on total and cause-specific mortality and cancer incidence in the post-intervention period; (2) to conduct a cross-sectional nutritional survey in a subsample of living trial participants to evaluate their nutritional status, asses the validity of dietary questionnaires, and relate neurologic status to vitamin B12 plasma levels; (3) to collect a blood sample from all living trial participants to permit further etiologic investigations of genetic and environmental hypotheses; and (4) to perform nested case-control studies of selected genetic and environmental hypotheses. To accomplish the objectives of the follow-up study, we will: (1) determine updated vital status and cancer status data on all trial participants via monthly checks of village doctor records and quarterly checks of the Linxian Cancer Registry; conduct a Vital/Cancer Status Interview Survey among all (n-34,000 trial participants (or their surrogates); identify, collect, and store all available diagnostic materials for trial participants identified as having developed cancer or died with cancer during the follow-up period; (2) conduct a Nutritional Survey on a subsample (n-1000) of living trial participants that will include (a) a physical exam and brief medical history, (b) a neurologic history, (c) a cognitive function exam, (d) a hair/mouth skin exam, (e) a neurological exam, (f) a nutritional questionnaire, and (g) collection of a blood sample for hematologic/biochemical analyses; (3) conduct a Blood Collection Survey of all living trial participants (n-23,000) to obtain (a) a physical exam and brief medical history and (b) a single 10-ml blood sample for separation and preservation as WBCs (both viable and nonviable), RBCs, and plasma for genetic (e.g., xenobiotic polymorphisms) and environmental (e.g., plasma ascorbic acid) hypothesis testing; and (4) perform Nested Case-Control Studies of selected genetic and environmental hypothesis related to the etiology and prevention of esophageal cancer and stroke. These will be done using serum from the new cancer and stroke cases (-2500) and controls (-2500) previously identified from 1991-1996, as well as using new cancer and stroke cases and controls for the period 1996-2004 (-9000). The followup for endpoints will continue monthly for an additional 5 years (through the year 2003). The Nutritional Survey and Blood Collection Survey will be conducted in the spring of 1999. The Nested Case-Control studies will be performed annually beginning in 2000, and the Vital/Cancer Interview Survey will be conducted in the Spring of 2001.

Impact of Prehabilitation in Oncology Via Exercise- Esophageal (IMPROVE-Esophageal)

The goal of this study is to determine the feasibility of a prehabilitation exercise and nutrition program (exercise and nutrition before a medical treatment) in adults with esophageal cancer before surgery (esophagectomy). The pre-surgery exercise and nutrition program will include resistance and aerobic training and nutrition supplementation during the weeks before surgery. We will also assess pre-surgical care needs in adults with esophageal cancer. Researchers will compare the exercise and nutrition intervention to usual care- which is standard medical care and post-surgery surveillance/follow-up to understand the impact of exercise and nutrition before surgery. We will follow-up with participants before surgery, and after surgery at 2 weeks, 6 weeks, and 4-months at appointments that coincide with clinical follow-ups. The main questions of this trials are: * Is exercise and nutrition supplementation before surgery for esophageal cancer feasible and acceptable to patients? * How does exercise and nutrition supplementation before surgery change physical function and psychosocial health? * What are important pre-surgical needs for adults with esophageal cancer?

EQUITY GI: A Prospective Study to Enhance Quality, Inclusivity, and Trial Participation in Black Patients With Gastrointestinal Cancer.

This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.

Hematoporphyrin Photodynamic Therapy for Esophageal Cancer

The objective of the present clinical trial is to assess the efficacy of photodynamic therapy (PDT) employing hematoporphyrin injection in the management of recurrent or residual superficial esophageal carcinoma. The principal objective is to determine the capability of this therapeutic modality to elicit a complete response in the patient cohort under investigation. The central research question that this study seeks to address is as follows: What is the rate of complete response at day 28 following treatment with photodynamic therapy utilizing hematoporphyrin injection in patients suffering from recurrent or residual superficial esophageal cancer? This study is designed as a single-arm trial, devoid of a control or comparison group. Eligible participants will meet the following criteria: They will be adult patients, aged between 18 and 80 years, who have experienced recurrence or retention of superficial esophageal cancer subsequent to prior therapeutic interventions. They will receive an intravenous administration of hematoporphyrin injection at a dosage of 3mg/kg over a duration of 60 minutes. They will undergo irradiation with a 630nm laser, which will be administered 48-72 hours post-infusion. Their response to treatment will be evaluated at day 28 post-therapy, with assessments encompassing complete response, progression-free survival, overall survival, swallowing functionality, quality of life, and the incidence of adverse events throughout the duration of the study

Chemoradiation Plus Iparomlimab Consolidation in Older With ESCC

This study was conducted in elderly (≥70 years old) patients with locally advanced esophageal squamous cell carcinoma (ESCC). Aim to evaluate the efficacy and safety of Iparomlimab consolidation therapy following concurrent chemoradiation with S-1 in elderly patients with unresectable locally advanced ESCC. Concurrent chemoradiation is the standard treatment for elderly esophageal cancer. However, the overall prognosis of patients still needs to be further improved. The emergence of immune checkpoint inhibitors has brought new hope for patients with ESCC. Iparomlimab can target both PD-1 and CTLA-4 immune inhibitory pathways simultaneously. Studies have shown that it can significantly improve the prognosis in the treatment of ESCC and has good tolerability. In elderly patients with ESCC, concurrent chemoradiation may potentially carry the risk of low treatment completion rate and significant toxicity. Therefore, this study aims to explore the efficacy and safety of Iparomlimab consolidation therapy following concurrent chemoradiotherapy in elderly patients with unresectable locally advanced ESCC. In the study, the investigators plan to enroll 52 elderly subjects with locally advanced ESCC. After receiving radiotherapy combined with the S-1 regimen, patients will enter the screening period. The enrolled patients will receive Iparomlimab consolidation therapy for 1 year. The treatment efficacy and safety will be evaluated.

Hypoxia Imaging for Esophageal Cancer to Guide Personalized Radiation Therapy

This is a Phase I trial evaluating the safety of personalized radiation therapy based on levels of hypoxia identified on FMISO-PET and MRI. All patients will receive a baseline FMISO positron emission tomography (PET) and MRI to identify levels of hypoxia. Patients with tumor hypoxia will receive a higher dose of radiation therapy. Subjects who do not have hypoxic tumors will be treated with the standard-of-care radiation regimen. After fraction 10 of radiation therapy, an additional MRI will be performed. If this interim MRI demonstrates little or no response (as defined in Section 6), an optional boost radiation dose can be administered. Trial enrollment will be conducted in two parts. In Part 1, eight patients will be enrolled. After all eight patients have completed the 30 day dose-limiting toxicity (DLT) period, enrollment will be placed on hold and safety will be evaluated. During the interim analysis, one additional patient will be allowed to be enrolled in the trial. If the trial meets stopping rules as described in Section 11.3, the trial will be re-evaluated by the Data and Safety Monitoring Committee (DSMC) and the Principal Investigator. However, if the rate of DLTs remains below the unacceptable toxicity rate, enrollment will open to the enrollment of eight more patients.

Exercise Training After Upper Gastrointestinal Cancer Surgery

This randomized controlled trial aims to determine the optimal exercise intensity for improving postoperative recovery in patients with upper gastrointestinal cancer. Participants who have undergone curative surgery will be randomly assigned to high-intensity interval training (HIIT), low-intensity continuous training (LICT), or usual care. The exercise interventions will be performed under supervision three times per week for eight weeks. The primary outcome is peak oxygen uptake (VO₂peak), assessed using cardiopulmonary exercise testing. Secondary outcomes include physical function, body composition, patient-reported outcomes, and biological and mechanistic markers such as inflammatory biomarkers, muscle-related factors, and gut microbiota. This study will also explore potential mechanisms underlying exercise-induced adaptations and their association with clinical outcomes.

Brodalumab in the Treatment of Immune-Related Adverse Events

The purpose of this study is to test the safety and effectiveness of using brodalumab in patients who develop side effects from cancer immune therapy. Immune-related side effects are due to activation of the immune system in patients who previously received immunotherapy and the goal of this study is to help better control these side effects. Brodalumab is often used to treat patients with autoimmune diseases (diseases where the immune system is activated against normal organs) and safe doses and treatment schedules have been determined in these patients. Immune-related side effects appear to closely mirror these autoimmune conditions. Brodalumab has not been approved by the United States Food and Drug Administration (FDA) for use in immunotherapy side effects but it has been approved for treatment of autoimmune conditions.
