Surgery in Gastrointestinal Stromal Tumors (GISTs) for Treatment, Tumor Modeling, and Genomic Analysis

Objective: To follow people with GISTs and collect tumor tissue so that it can be studied in the lab. Eligibility: People age 6 and older who have a GIST. Design: Participants will be screened with a review of their medical records and samples. Participants will enroll in 1 other NIH study, and may be asked to enroll in 2 other optional NIH studies. Participants will have a medical history and physical exam. Data about how they function in their daily activities will be obtained. Participants may speak with a genetic counselor. They may have genetic testing. Participants will give blood samples. They may have a cheek swab. For this, small brush will be rubbed against the inside of the cheek. Participants may have a computed tomography (CT) scan of the chest, abdomen, and pelvis. Or they may have a CT scan of the chest and magnetic resonance imaging (MRI) of the abdomen and pelvis. Participants will be monitored every 6-12 months at the NIH Clinical Center, for up to 10 years before having surgery. If they need surgery, it will be performed at the NIH. Then, they will be monitored every 6-12 months, for up to 5 years after surgery. If a participant has surgery, tumor tissue samples and research specimen will be taken. If a participant does not need surgery, their participation will end after 10 years. If they have surgery, the 5-year monitoring period will restart after each surgery.

Tumor Cell and DNA Detection in the Blood, Urine, and Bone Marrow

Patients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Also, early detection of lung cancer with low dose CT screening may cure patients at an early stage. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies and improve screening.

Stomach-Partitioning Versus Conventional Gastrojejunostomy for Malignant Gastric Outlet Obstruction: A Multicenter Randomized Controlled Trial

Gastric outlet obstruction (GOO) complicates locally advanced or metastatic gastric cancer and severely impairs oral intake, nutritional status, and quality of life. Conventional gastrojejunostomy (CGJ) effectively relieves the obstruction but is associated with a high incidence of delayed gastric emptying (DGE), which delays the resumption of oral intake and the initiation of systemic anticancer therapy. Stomach-partitioning gastrojejunostomy (SPGJ) isolates the tumour-bearing distal stomach from the alimentary tract and has been suggested, in retrospective studies, to reduce the incidence of DGE. However, no randomized evidence is currently available, and the comparative safety and efficacy of SPGJ and CGJ remain uncertain. This multicenter, randomized, open-label, blinded-outcome-assessment trial will randomly assign 80 participants with unresectable distal gastric adenocarcinoma complicated by GOO, in a 1:1 ratio, to undergo either SPGJ or CGJ. The primary endpoint is the incidence of postoperative DGE within 30 days after surgery.

Comparison of Molecular-Genetic Concordance of the Primary Tumor and Brain Metastases of Gastroesophageal Cancers

GENCONCOR-2 is a translational research aimed to compare the molecular profile of primary tumors and their matched brain metastases in gastroesophageal cancers, including cancer of the esophagus, gastroesophageal junction, and stomach. The study is based on the previously established international GASTROBRAIN cohort (ClinicalTrials.gov ID: NCT07448493), which provides comprehensive clinicopathological and treatment data for over 230 patients. It will be conducted by retrospective analysis of paired samples of histological material (primary tumor and corresponding brain metastasis) with determination of HER2 expression status (IHC ± FISH), MSI status (IHC ± PCR), PD-L1 combined positive score (CPS), and CLDN18.2 expression status (IHC)

Distance-Based Exercise to Preserve Function and Prevent Disability

This clinical trial studies whether an exercise program can be successfully delivered to patients receiving treatment for cancer through virtual sessions and allow patients to exercise in their own home. Treatments for cancer can cause side effects such as fatigue and loss of strength. These side effects can make it difficult to work, take care of family, and do other things the patient wants to do. Preliminary research shows that exercise can help prevent some of these side effects, but it can be more difficult to start an exercise program when a patient is receiving cancer treatment. The exercise program in this study is delivered through telehealth (TH) video calls. The TH sessions are delivered by trained staff that supervise resistance exercises. The trained staff also provide guidance to the patient on completing unsupervised aerobic sessions on their own. This may be a successful way to deliver an exercise program and make it easier for cancer patients to exercise in their own home during treatment.

A Study With NKT3964 for Adults With Advanced/Metastatic Solid Tumors

The goal of the Monotherapy Dose Escalation phase (Part 1) of the study is to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity to determine the preliminary recommended dose for expansion (RDE) of NKT3964 in adults with advanced or metastatic solid tumors. The goal of the Monotherapy Expansion phase of the study (Part 2) is to evaluate the preliminary anti-tumor activity of NKT3964 at the RDE based on objective response rate (ORR) and determine the preliminary recommended Phase 2 dose (RP2D). The goal of the Combination Dose Escalation phase (Part 3) of the study is to identify the RDE of NKT3964 in combination with chemotherapy in adult subjects with advanced/metastatic endometrial cancer. The goal of the Combination Expansion phase of the study (Part 4) is to evaluate the preliminary anti-tumor activity of NKT3964 in combination with chemotherapy at the RDE based on ORR.

Combination of Osemitamab (TST001), Pembrolizumab and Chemotherapy as First-line Therapy in Advanced or Metastatic GC/GEJ Adenocarcinoma

Gastric/GEJ adenocarcinomas are aggressive tumors with a high probability of death. Current treatment guidelines include two-drug cytotoxic chemotherapy with a fluoropyrimidine (mFOLFOX6: capecitabine or fluorouracil) and a platinum-based agent (CapOx: oxaliplatin or cisplatin). In addition, the FDA has approved nivolumab, a PD-1 checkpoint inhibitor, in combination with chemotherapy as first line treatment for advanced or metastatic gastric/GEJ cancer. TST001 is a recombinant humanized monoclonal antibody against Claudin 18.2 (a tumor marker found in gastric/GEJ cancer. In this study, the combination therapy of chemotherapy or chemotherapy and pembrolizumab with and without TST001 could provide additional benefits to the management of these tumors.

Prehabilitation in High-risk Oncologic Surgery

The goal of this clinical study is to learn whether a prehabilitation program can improve recovery after major abdominal surgery in adults with cancer who are receiving treatment before surgery. Prehabilitation is supportive care given before surgery to help patients prepare physically, nutritionally, and emotionally. The main questions this study aims to answer are: 1. Does prehabilitation reduce the number of participants who die or have serious complications within 30 days after surgery? 2. Does prehabilitation improve physical strength and fitness, nutritional status, emotional well-being, and quality of life before surgery? 3. Does prehabilitation affect the length of the hospital stay after surgery, the time it takes to start additional cancer treatment after surgery, or the ability to complete recommended additional treatment? Participants will take part in a prehabilitation program during their treatment period before surgery. The program includes visits with physical therapy, nutrition, and health psychology. Participants will meet with each specialty at least twice before surgery. They will also complete questionnaires and tests that measure physical function, diet and weight, emotional well-being, and quality of life. After surgery, information about recovery and additional cancer treatment will be collected from medical records for up to 120 days. Researchers will compare the outcomes of participants who receive the prehabilitation program with outcomes from similar patients who previously received care at Fox Chase Cancer Center but did not participate in this study.
