Abstract
Background:
Knowledge of clinically established factors of physical function such as body
composition, bioelectrical phase angle (PhA) and handgrip strength (HGS)
with mortality predictive and health-related relevance is limited in
prostate cancer survivors (PCS). Therefore, the aim of this study was to
characterise and compare body composition data of PCS with extensive
reference data as well as to analyse PhA and HGS and the prevalence of
critical prognostic values at an early stage of cancer survivorship.
Methods:
One hundred and forty-eight PCS were examined at the start (T1) and end (T2)
of a 3-week hospitalised urooncological rehabilitation, which began median
28 days after acute cancer therapy. Examinations included a bioimpedance
analysis and HGS test. Comparison of body composition between PCS and
reference data was performed using bioimpedance vector analysis (BIVA).
Results:
BIVA of the whole PCS group showed abnormal physiology with a cachectic state
and a state of overhydration/oedema, without significant changes between T1
and T2. The age- and BMI-stratified subgroup analysis showed that PCS aged
60 years and older had this abnormal pattern compared to the reference
population. HGS (T1: 38.7 ± 8.9 vs T2: 40.8 ± 9.4, kg), but not PhA (T1/T2:
5.2 ± 0.7, °), changed significantly between T1 and T2. Values below a
critical threshold reflecting a potentially higher risk of mortality and
impaired function were found for PhA in 20% (T1) and 22% (T2) of PCS and in
41% (T1) and 29% (T2) for HGS.
Conclusions:
BIVA pattern and the prevalence of critically low HGS and PhA values
illustrate the necessity for intensive continuation of rehabilitation and
survivorship care especially in these ‘at risk’ cases. The routine
assessment of body composition, PhA and HGS offer the opportunity to conduct
a risk stratification for PCS and could help personalising and optimising
treatment in rehabilitation and ongoing survivorship care.
