Study summary

The goal of this study is to improve the monitoring of fluid retention in cancer patients. The main question it aims to answer is: Can segmental bioelectrical impedance analysis be used to monitor local fluid retention (edema) in cancer patients? We will include:

  • Breast cancer patients with fluid and or lymph retention in one or both arms after radiotherapy (outpatients)
  • Cancer patients with fluid retention in one or both legs after chemotherapy (hospitalized)

Participants will:

  • Have measurements taken using bioelectrical impedance
  • Provide blood samples and 24-hour urine collection
  • Weight monitorering
  • Complete diet and fluid registration (inclusive enteral and parenteral)
  • Have clinical palpatory and measurement assessment of oedema.
Read the detailed description

Both groups will undergo measurements over a maximum period of six days.

Outpatients:

Outpatients will complete three measurement cycles, each consisting of two consecutive days:

  • Day 1: Home-based dietary and fluid intake registration and 24-h urine collection
  • Day 2: Hospital-based assessment including bioelectrical impedance analysis (BIA), blood sampling, body weight measurement, and clinical palpatory assessment

Each measurement cycle will be separated by a 7-14-day interval.

Hospitalized patients:

Hospitalized patients will undergo up to six consecutive measurement days, or until discharge or transfer to another ward:

  • Days 1, 3, and 5: Dietary and fluid intake registration and 24-h urine collection
  • Days 2, 4, and 6: Bioelectrical impedance analysis (BIA), blood sampling, body weight measurement, and clinical palpatory assessment

If the treating physician administers i.v. loop diuretics to the hospitalized patient, additional measurements will be taken before administration and hourly for five hours thereafter, as these may significantly affect fluid levels.
