Tracking fluid buildup (edema) in people with cancer

Monitoring of Oedema in Cancer Patients - A Pilot Study

Observational University of Copenhagen · NCT07443618

This will try segmental bioelectrical impedance analysis to see if it can monitor local fluid buildup in cancer patients who have arm or leg swelling after radiotherapy or chemotherapy.

What this trial studies

The study enrolls two groups—outpatients with arm lymphoedema after breast radiotherapy and hospitalized cancer patients with leg oedema after chemotherapy—and collects repeated measurements over several days. Measurements include segmental bioelectrical impedance analysis (BIA), blood sampling, 24-hour urine collection, body weight, diet and fluid intake logs, and clinical palpatory assessment. Outpatients complete three two-day measurement cycles separated by 7–14 days, while hospitalized patients undergo up to six consecutive measurement days with alternating measurement and collection days. If hospitalized patients receive IV loop diuretics, extra BIA and clinical measurements are taken before and hourly for five hours after administration.

Who should consider this trial

Good fit: Adults (≥18) who read and speak Danish and have visible lymphoedema in at least one arm within 6 months after breast radiotherapy (outpatients followed at Aalborg) or visible peripheral leg oedema within 2 months after chemotherapy while hospitalized in the Oncology Ward are ideal candidates.

Not a fit: People who are pregnant or breastfeeding, have amputated limbs, have implanted pacemakers/ICDs, cannot read or speak Danish, or are not treated/admitted at Aalborg University Hospital are excluded and unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could provide a simple, noninvasive way to detect and track local fluid retention so treatments can be timed and adjusted more effectively.

How similar studies have performed: Similar applications of bioelectrical impedance for lymphedema and localized oedema have shown promising but mixed results in small studies, so the method is plausible but not yet definitively proven.

* Must be able to speak and read Danish
* Has received/is receiving radiotherapy due to breast cancer within the last 6 months
* Is being followed in the Oncology Outpatient Clinic at Aalborg University Hospital

Exclusion Criteria (both groups):

* Pregnant or breastfeeding women
* Amputated limb(s)
* Pacemaker or implanted cardioverter-defibrillator due to risk of interference from the electrical signal
