Abstract:
Background: Breast cancer-related lymphedema (BCRL) is a debilitating chronic illness. Early management and prevention of disease progression rely on lymphedema monitoring and assessment. At present, lymphedema monitoring systems are costly and do not promote remote monitoring. Thus, a low-cost, portable, mobile-based bioimpedance lymphedema monitoring system (Mobilymph) was developed to ensure continuous lymphedema surveillance. Method and Results: Forty-five healthy and 100 BCRL participants were recruited in this study. Mobilymph bioimpedance measurement was validated with a Quadscan 4000 on healthy participants' arms. The interarm bioimpedance ratio was determined to evaluate the discriminatory capability of Mobilymph to detect BCRL. Mobilymph's bioimpedance results show no significant difference compared to Quadscan 4000. The interarm bioimpedance ratios were significantly different (p < 0.001), between participants in healthy and Stage 1, Stage 0 and Stage 1, and Stage 1 and Stage 2. Healthy and Stage 0 participants had similar interarm impedance ratios (p = 0.63). Conclusion: The bioimpedance results show that Mobilymph bioimpedance measurement is comparable to Quadscan 4000 and can detect BCRL arms. Thus, Mobilymph lymphedema monitoring system offers a feasible solution for early lymphedema diagnosis and treatment monitoring. Clinical trial registration number: MREC ID No.: 2020316-8181.
