Frailty may be key to predicting surgery survival in the very old
NCT ID NCT07440095
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study examines whether frailty and simple blood tests can predict which patients aged 80 and older are most likely to die within 30 days after major abdominal surgery. Researchers will review records of 100 patients to see if a frailty index and lab markers like albumin and hemoglobin offer better risk prediction than standard methods. The goal is to improve surgical decision-making and pre-surgery care for the oldest patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better identify which very elderly patients are at highest risk after major abdominal surgery, leading to more informed decisions and possibly pre-surgery strengthening programs.
- What could go wrong
- This is a small, retrospective study (100 patients) from a single hospital, so results may not apply to all older adults. It only looks at risk factors, not a treatment.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population consists of "old-old" patients (aged 80 years and older) who underwent major abdominal surgery at a tertiary oncology center (Dr. Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital) between January 2022 and December 2025. This population includes patients who received surgical interventions in the departments of surgical oncology, gynecologic oncology, and urologic oncology. The sample represents a high-risk geriatric group undergoing complex oncological or major abdominal procedures, where frailty and physiological reserve are critical factors for survival.

Inclusion Criteria: * Patients aged 80 years and older * Underwent major abdominal surgery between January 2022 and December 2025 * Availability of at least 30 days of postoperative follow-up data * Complete medical records available in the hospital information system Exclusion Criteria: * Patients under 80 years of age * Underwent surgical procedures other than major abdominal surgery * Missing or incomplete follow-up data within the first 30 days postoperatively * Insufficient data for the assessment of frailty (mFI-5) or physiological reserve parameters (e.g., missing preoperative laboratory values)
