What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only

Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how often cancer patients with risk factors like age, diabetes, or smoking have peripheral arterial disease (PAD), a condition where blood vessels narrow. Researchers will test 114 patients before surgery using simple ankle and toe blood pressure measurements. The goal is to understand how common PAD is and whether it affects recovery, especially across different racial groups.

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 this study succeeds, it could show that many cancer patients have undiagnosed PAD, leading to routine screening and better surgical outcomes.
What could go wrong
This is an observational study with only 114 participants, so results may not apply to all cancer patients. It does not test any treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Cancer patients who are ≥ 65 years old * Either diabetes (on medication or insulin) or smoking history (current smoker, smoking within the last 15 years, ≥ 20 pack years) * Patients who are scheduled for major head and neck, thoracic, abdominal, or pelvic surgery requiring at least a 2-day admission * Ambulatory * ≥ 6 month life expectancy as determined based on clinical judgement by the treating physician.
