2025 In ReviewMoving Forward in 2026Research Impact

2025 in review . . . moving forward in 2026. Research funding, community support, and collaborations that keep LMS research moving when other funding is paused or delayed.

Introduction

Since 2001, the National Leiomyosarcoma Foundation (NLMSF) has been working to:

  • Fund LMS-specific research to advance the field of study and accelerate development of clinical trials and treatments.
  • Support the LMS patient, family, and caregiver community through education, information sharing, resource assistance, and 24/7 direct phone support.
  • Raise global, national, and community awareness of leiomyosarcoma.
  • Address unmet needs in treatment, research, clinical trials, and care through the Foundation's International LMS Research Roundtable, in which researchers, clinicians, partner organizations, and the LMS community collaborate to achieve meaningful progress.

Research funding is the backbone of transforming patient treatment and, ultimately, survivorship. At a time when much research funding has been paused or delayed, philanthropic support is more critical than ever to keep LMS research moving forward.

New drug discoveries are being tested all the time, but it takes money to continue the research. We aim to fuel the future of research breakthroughs for more options besides the 40-year-old drugs that have been relied upon for years for LMS treatment. Repurposing drug discoveries is also an important focus of this Foundation.

The power of people coming together is what makes all the difference. Together with the LMS-sarcoma community, we continue to move forward to pursue these objectives.

2025 In Review

NLMSF 2025 Research Awardees

The following grant was awarded in 2025, with funding for 2026–2027

Robert J. Canter, MD

Chief, Dept. of Surgery, UC Davis Comprehensive Cancer Center, Sacramento, CA

Research Project: Pre-Clinical Evaluation of Placental-Derived Natural Killer (NK) Cells to Target Leiomyosarcoma. The project focuses on this hypothesis: Placental-derived NK cells are more stem-like, leading to greater persistence in vivo compared to other sources of NK cells such as peripheral blood mononuclear cells (PBMCs), thereby paving the way to improved and more durable anti-tumor effects in LMS patients.

Funding begins in 2026.

Continuing Research Funding (2025)

The following grant was awarded in 2024, with one-year funding during 2025

Everett Moding, MD

Physician-scientist, Department of Radiation Oncology, Stanford University — with Maggie Zhou, MD, instructor in the Division of Oncology at Stanford. Special LMS project associated with the SARC Catalyst Program.

Research Project: Correlative analysis of CSF-1R blockade and immunotherapy in leiomyosarcoma. Drs. Moding and Zhou will analyze tumor and blood specimens collected from a clinical trial combining CSF-1R blockade and immunotherapy in patients with leiomyosarcoma. They aim to show that CSF-1R blockade can improve the efficacy of immunotherapy by blocking the recruitment of immunosuppressive macrophages and targeting leiomyosarcoma tumor cells.

Co-funded by NLMSF and the LMS Support and Direct Research Foundation; administered by SARC (Sarcoma Alliance for Research through Collaboration).

The following two grants were awarded in 2024, with funding for 2025–2026

Frederic Amant, MD, PhD

Professor of Gynecologic Oncology at the University of Leuven, Univ. Hospitals Leuven, Belgium

Research Project: Exploiting the Immunomodulatory Effect of PI3K/mTOR Inhibitors to Improve Immunotherapy Response in Leiomyosarcoma. This research explores how enhancing the adaptive immune response in LMS tumors through PI3K/mTOR inhibition may render them more responsive to ICB, a downstream target of the PI3K/mTOR pathway, potentially serving as a predictive biomarker for response. The project investigates the immunomodulatory effects of PI3K/mTOR inhibitors on the tumor microenvironment (TME) and their capacity to overcome primary ICB resistance in LMS, integrating LMS humanized PDX models with immune checkpoint inhibition to reshape the tumor microenvironment in response to PI3K/mTOR inhibition and/or PD-1 blockade.

First year of 2-year funding.

Marisa Nucci, MD

Division Chief, Perinatal Pathology, Brigham and Women's Hospital; Professor of Pathology, Harvard Medical School, Boston, MA

Research Project: Exploiting High-throughput Deep Learning to Improve Uterine Leiomyosarcoma Diagnostics — Deep ULMS. This project aims to establish an innovative platform utilizing advanced Artificial Intelligence techniques for the comprehensive characterization of uterine leiomyosarcoma. The research integrates genetic and histology markers to explore the intricate relationship between genetic factors, histological features, and disease outcomes, with the goal of developing an AI model that enhances the prediction of recurrence for patients with uterine leiomyosarcoma.

First year of 2-year funding.

The following two grants were awarded in 2023, with funding for 2024–2025

Priya Chudasama, PhD

These presentations are also recorded and made available on our website for later viewing. View programs

Clinical Trials: Patient/Caregiver Perspectives

This discussion group meets on Zoom several times per year to discuss patient and caregiver experiences with clinical trials and suggestions on how trials could be improved. NLMSF board members serve on various committees with clinical trial working groups and can convey valuable suggestions generated in this group to clinicians planning / running clinical trials.

Caregiving Counts Advocacy Network

This discussion group, held several times per year via Zoom, is focused toward caregivers but patients are encouraged to attend. Caregivers relatively new to LMS find it extremely helpful to hear from those who have been there before. (Includes podcasts and handout materials.)

THE ABC's of the LMS Diagnosis and Treatment Journey

This program / discussion group for new and existing patients and their families is held via Zoom several times per year. We talk about initial steps for newly diagnosed patients, finding a sarcoma center for treatment, questions to ask at appointments, how to talk to the oncology care team, and more. This group is useful to patients in all phases of diagnosis and treatment. ABC's of a new diagnosis

Survivorship Care Clinic

This occasional online discussion group covers the significance, objectives, and usefulness of having a survivorship care plan in place both during and after cancer treatment. A plan helps patients and their healthcare teams manage ongoing healthcare needs, address any potential long-term side effects, and ensure a smooth transition into post-treatment life. (Notes from each meeting, podcasts, and handout materials are available.)

Wellness – Integrative Medicine Guidance for Patients

This series was new in 2024 and continued in 2025. It incorporates nutrition, exercise, and psychosocial well-being and includes survivorship peer clinic sessions for patients, throughout the course of treatment and afterwards. Nutrition and physical activity
