Safety and Efficacy of NOM and OPFS Versus RO for dMMR/MSI-H or POLE-Mutated Gastrointestinal Cancers

Purpose: The purpose of this study is to evaluate the safety and efficacy of Non-Operative Management (NOM) and Organ Preservation First Strategy (OPFS) compared with Radical Operation (RO) in patients with deficient mismatch repair/microsatellite instability-high (dMMR/MSI-H) or POLE-mutated gastrointestinal cancers. Background \& Design: With the remarkable efficacy of neoadjuvant immunotherapy in dMMR/MSI-H or POLE-mutated gastrointestinal tumors, organ preservation has become a promising alternative to highly invasive surgeries. The NOR-MP trial is a single-center, bidirectional registry study consisting of two parts: a retrospective cohort study and a prospective observational registry. Intervention Group (NOM/OPFS): Patients who achieve a clinical complete response (cCR) or near-cCR after neoadjuvant immunotherapy will undergo a "Watch \& Wait" (W\&W) strategy. Patients with near-cCR or non-cCR who are eligible for organ preservation will undergo local excision (LE) or endoscopic resection (including ESD or EMR). Comparison Group (Radical Operation): Patients who undergo standard radical surgical resection after neoadjuvant immunotherapy. The study aims to determine whether an organ-preserving approach can achieve comparable oncological outcomes and safety profiles while significantly improving patients' quality of life compared to radical surgery.

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.
