Abstract

Purpose

The aim of this study was to determine the clinical utility of bioelectrical impedance analysis (BIA) in a cohort of patients with advanced urothelial carcinoma (UC).

Methods

We prospectively evaluated body composition in 35 patients with locoregional muscle invasive (≥ T2 and N0–2M0) or metastatic UC. Body composition was evaluated using multifrequency BIA at baseline (n = 35) and during chemotherapy in patients receiving neoadjuvant chemotherapy (n = 14). The BIA-predicted body composition index was compared with the computed tomography-measured muscle index and the prognostic nutrition index. Changes in body composition during neoadjuvant chemotherapy were recorded and compared with the incidence of hematological adverse events.

Results

There was a significant correlation between the BIA-predicted skeletal muscle index and the computed tomography-measured skeletal muscle index (P = 0.004), while there was no significant correlation between the prognostic nutrition index and the BIA-predicted nutrition index. After the completion of 3 cycles of neoadjuvant chemotherapy, the skeletal muscle index showed a significant decrease (P = 0.016), while the total body fat mass (P = 0.025), body fat percentage (P = 0.013), and body mass index (P = 0.004) showed a significant increase (a tendency toward “sarcopenic obesity”). Patients who experienced grade 2–3 anemia during neoadjuvant chemotherapy showed a significantly lower increase in body mass index compared with patients who did not experience high-grade toxicities (P = 0.032).

Conclusions

BIA could contribute to other methods of nutrition and muscle assessment for pretreatment risk stratification in patients with UC. Further study of a larger cohort is required to elucidate the clinical impact of changes in body composition during chemotherapy.
