Virtual Reality for GI Cancer Pain to Improve Patient Reported Outcomes

Patients with digestive tract malignancy often experience severe and unremitting abdominal pain that negatively affects physical, emotional, and social function, as well as health related quality of life (HRQOL). Therapeutic virtual reality (VR) has emerged as a promising and evidence-based treatment modality for cancer pain. Users of VR wear a pair of goggles with a close-proximity screen in front of the eyes that creates a sensation of being transported into lifelike, three-dimensional worlds. To date, VR has been limited to short-term clinical trials for cancer pain. Moreover, limited research exists on theory-based VR modalities beyond mere distraction, such as VR that employs acceptance and commitment therapy (ACT) with components of biofeedback and mindfulness. To bridge these gaps, this study seeks to: (1) assess the impact of immersive VR on patient-reported outcomes (PROs), including pain, activity metrics, and opioid use among patients with visceral pain from a digestive tract malignancy; (2) assess differences in PROs, activity metrics, and opioid use between skills-based VR therapy vs. distraction VR therapy; and (3) determine patient-level predictors of VR treatment response in visceral cancer pain. To address these aims, the study will measure PROs and opioid use in 360 patients randomized among 3 groups and follow them for 60 days after enrollment: (1) an enhanced VR group receiving skills-based VR; (2) a distraction-based VR group receiving patient-selected VR videos; and (3) a VR sham control group using a VR headset with 2-D content. The results will inform best practices for the implementation of VR for visceral cancer pain management and guide selection of patient-tailored experiences.

A Phase Ib/II Trial of Neoadjuvant Zolbetuximab Plus Docetaxel, Oxaliplatin and S-1 Chemotherapy in Patients With Locally Advanced Gastric Cancer

Claudin 18.2 is a promising therapeutic target overexpressed on the surface of gastric cancer cells. The addition of zolbetuximab, the monoclonal antibody targeting Claudin 18.2 to chemotherapy in two recent Phase 3 studies prolonged survival outcomes, indicating that Claudin 18.2 is a valid target in gastric cancer. Asan Medical Center researchers conducted a study on Claudin 18.2 expression in patients with operable gastric cancer and defined moderate to strong claudin expression in more than 75% of tumor cells as Claudin 18.2 overexpression, which was observed in 46.5% of patients with stage I-III tumors. This suggests that zolbetuximab-based treatment may be possible in patients with LAGC. Therefore, The investigator designed a prospective, multicenter, open-label, Phase Ib/II study to determine the efficacy and safety of zolbetuximab/DOS as neoadjuvant chemotherapy in patients with LAGC.

Timing of Minimally Invasive Local Treatment After First-Line Systemic Therapy in Oligometastatic Esophageal or Gastric Adenocarcinoma

Purpose of the Study: This clinical study investigates whether a shorter or longer duration of systemic therapy before local treatment (surgery or radiation) results in better disease control in patients with esophageal or gastric cancer with a limited number of metastases, also known as oligometastases. Background: In about 25% of patients with advanced esophageal or gastric cancer, the disease spreads to only a few sites (oligometastatic disease). Prior studies suggest that local treatment after systemic therapy may extend survival in this subgroup. However, it is unclear how long systemic therapy should last before initiating local treatment. The OMEC-5 study aims to clarify this and identify potential biomarkers for treatment response. Study Design: Initiated by Amsterdam UMC and UMCU and conducted in multiple hospitals across Europe. Total of 414 patients to be enrolled. Duration: \~53 months (35 months enrollment + 18 months follow-up). Approved by the medical ethics committee at Amsterdam UMC. Procedure: Eligibility screening: Includes physical exam, blood tests (incl. circulating tumor cells), medical history review, and confirmation of oligometastases by an expert panel. Initial treatment: All participants receive 4 months of standard systemic therapy (chemotherapy + immunotherapy and/or targeted therapy depending on tumor markers like HER2 or Claudin 18.2). Response assessment (Review 1): Imaging and/or laparoscopic examination. If oligometastases persist and tumors have not progressed, participants are randomized into two groups: Group A (longer systemic therapy): 4 more months of systemic therapy, then local treatment if disease is stable, followed by 4 months of immunotherapy ± targeted therapy. Group B (shorter systemic therapy): Immediate local treatment followed by 4 months of systemic therapy, then reassessment and potentially 4 months of immunotherapy ± targeted therapy. Follow-up: Regular scans and quality-of-life questionnaires (5 times), and periodic blood sampling (4 times). Treatments Involved: Chemotherapy: CapOx or FOLFOX Immunotherapy: nivolumab or pembrolizumab Targeted therapy: trastuzumab (HER2-positive) or zolbetuximab (Claudin 18.2-positive) Potential Benefits and Risks: Patients may benefit from better disease control and a personalized treatment strategy. Known side effects relate to the standard treatments used (chemo, immuno, targeted therapies), and no extra medical risk is expected beyond routine care. Possible inconveniences include blood draws, scans, minor surgery (laparoscopy), and time investment. Data and Sample Handling: Personal data and tumor/blood samples are coded and securely stored. Data may be used for future cancer research if the patient consents. Participants can withdraw at any time. Confidentiality and Privacy: Patient data are kept confidential, and participants have rights to access or delete their data. Privacy measures comply with GDPR and Dutch law. Compensation and Insurance: Participation is voluntary, with no financial compensation. Standard treatment costs are covered by healthcare insurance. No extra insurance is required, as the treatment aligns with standard care practices.

A Study on the Impact of Intelligent Nutrition Management on Clinical Outcomes in Chemotherapy Patients With Gastrointestinal Malignancies

An increasing body of evidence suggests that nutritional status is a key factor in determining the quality of life of cancer patients. The sensitivity of cancer patients to anti-tumor treatments, the occurrence of side effects, and their quality of life are closely related to their nutritional status. Data show that about 50% of cancer patients experience a weight loss of more than 10% at the time of diagnosis and treatment, and once patients enter a cachexia state, the weight loss becomes difficult to reverse. Therefore, the extent to which nutritional interventions can impact clinical outcomes in these patients needs to be answered through clinical research. Currently, there are few studies using randomized controlled trials (RCTs) to explore how nutritional interventions can improve patients' quality of life, particularly in terms of prolonging survival. A recent RCT in a smaller sample population found that long-term, intensive, individualized nutritional counseling and support not only improved malnutrition in cancer patients, reduced treatment complications, and enhanced quality of life but also significantly extended survival time. This study is a prospective, randomized controlled clinical trial aimed at investigating the effect of full-scale intelligent nutrition management in gastrointestinal malignancy patients (esophageal cancer, gastric cancer) undergoing chemotherapy. The study attempts to confirm that full-scale intelligent nutrition management can benefit these patients by maintaining or improving their nutritional status, and that the clinical effectiveness of intelligent nutrition management is comparable to that of professional nutritionists. This research will also provide clinical evidence for the intelligent and standardized nutritional treatment of cancer patients during the chemotherapy period.
