Exercise before surgery may slow cancer growth
NCT ID NCT04025229
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at whether high-intensity interval training (HIIT) — short, intense exercise sessions — could have anti-cancer effects in women with endometrial cancer. Thirty women did 4 to 6 HIIT sessions before their scheduled surgery. Researchers then checked tissue samples for changes in a marker called Ki-67, which indicates how fast cancer cells are growing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- High-intensity interval training (HIIT) exercise
- What this could lead to
- If this works, it could point toward exercise as a way to slow tumor growth before surgery for endometrial cancer.
- What could go wrong
- This is a very small, early study with only 30 participants and no comparison group, so results may not be reliable or apply to others.

Inclusion Criteria: * Patients with a diagnosis of endometrial cancer who are to undergo hysterectomy and staging * Between 40-75 years old * Body mass index of 30-50 kg/m2 * Endometrioid histology endometrial cancer * Presumed clinically early stage disease (disease confined to uterus only) * Have access to a Smart Phone * Have access to email * Agree to visit the exercise and sport science laboratory within 2 days of SOC visit for baseline testing if enrollment procedures cannot be done on the same day. Agree to visit clinic 2 (+/-2wks) weeks after surgery for SOC follow-up and post surgery visit, or willing to return to exercise and sport science laboratory 2 (+/-2wks) weeks post-surgery Exclusion Criteria: * Meets American College of Sports Medicine Guidelines for physical activity (150 minutes / week) * Currently doing HIIT * Hospitalization for a stroke, heart attack, or heart failure, or had surgery for blocked arteries in the past 3 months * Active diagnosis of psychosis or current uncontrolled substance abuse disorder * Insulin-dependent diabetes * Currently in another EC intervention * Severe dementia or other memory loss condition * Severe mental health disorder * Severely impaired hearing or speech * Inability to speak English * Musculoskeletal or neuromuscular condition that limits physical activity Any condition, in the opinion of the investigators, which would prohibit safe participation.
