Do you believe increasing physical activity before surgery is a reliable way to improve your recovery?
Regular physical activity may be linked to a lower risk of developing postoperative delirium in cancer patients, according to new research. The study examined tumor resection patients to determine how activity levels impact recovery outcomes.
Why it matters
Postoperative delirium can complicate recovery after cancer surgery, making it critical to identify modifiable factors that might reduce this risk. This study suggests that habitual physical activity may play a role in protecting patients during the post-surgical period.
This retrospective study analyzed 64 cases of postoperative delirium and 194 controls who underwent tumor resection between 2024 and 2025. Patients reporting moderate or vigorous physical activity seven or more times per week showed an adjusted odds ratio of 0.49 for delirium.
The players
ANESTHESIOLOGY
The annual meeting held by the American Society of Anesthesiologists, which focuses on the latest evidence in perioperative care and patient safety.
The details
Researchers retrospectively identified patients using operative reports for procedures including gastrointestinal and genitourinary resections. By comparing physical activity and sedentary habits between those who developed delirium and those who did not, the investigators sought to identify behavioral patterns associated with better cognitive outcomes. Notably, the study found no significant association between total daily sedentary behavior and the likelihood of delirium.

Health Landscape
This research builds on existing perioperative care efforts like the Enhanced Recovery After Surgery (ERAS) protocols. It shifts the focus toward how patient lifestyle behaviors before surgery might serve as a protective layer against cognitive complications during recovery.
If you are preparing for tumor resection, it is worth discussing your current activity levels and recovery plan with your surgical team. While preliminary, these findings reinforce the potential value of maintaining regular physical activity in the lead-up to any major procedure.
The takeaway
Maintaining a regular habit of moderate or vigorous exercise may help protect against delirium after surgery. Patients preparing for cancer procedures should discuss their fitness goals and post-surgical recovery plans with their doctors to identify safe ways to stay active.
