“…In this respect, bioimpedance spectroscopy would have been valuable in terms of measuring the extracellular fluid directly. 31 Previous studies indicate an overall trend in favor of PRT, as illustrated by the most recent meta-analysis, in which pooled data from 5 PRT trials during or after adjuvant treatment in women with or at risk for lymphedema indicated a significantly lower risk of incidence/exacerbation (odds ratio, 0.53; confidence interval, 0.31-0.90). 8 When the 2 trials from this meta-analysis that tested PRT during adjuvant treatment in women at risk for lymphedema were isolated, 15,16 no protective effect was found with no statistically significant difference between groups.…”

Background Existing research suggests that progressive resistance training (PRT) after breast cancer (BC) surgery is safe, but the preventive effect on arm lymphedema has yet to be determined. Methods Women aged 18 to 75 years who were undergoing BC surgery with axillary lymph node dissection were eligible for the study. Recruited on the day of surgery, participants were allocated to intervention or usual care by computer randomization. The intervention consisted of PRT 3 times per week: in the first 20 weeks as a supervised group exercise and in the last 30 weeks as a self‐administered exercise. The primary outcome was arm lymphedema, which was defined as a >3% increase in the interlimb volume difference by water displacement. Measurements were made at the baseline and at a 12‐month follow‐up by physiotherapists blinded to group allocation. Analyses of effects included t tests and regression models; missing data were addressed by multiple imputation. Results Among the 158 randomized women, no mean group difference was found in arm volume (0.3%; 95% confidence interval, –1.7% to 2.3%) or lymphedema incidence (adjusted odds ratio, 1.2; 95% confidence interval, 0.5‐2.8). None of the participants exited the program because of adverse events. Conclusions This study provides no evidence that PRT can prevent arm lymphedema in the first year after BC, but the results corroborate the importance and safety of resistance training for patients, including women at high risk for lymphedema.

“…BIA also is a non-invasive measure and is convenient for both the physician and the patients. Reference values for healthy populations and standards for diagnosis of lymphedema have been established for BIA (33). However, considering individual variability especially noted for obese individuals (34), the patient's longitudinal value after CDT can be used as a reference during longterm maintenance.…”

Background: Cancer treatment-related lymphedema (CTRL) affects patients physically, psychologically and emotionally, and remains a significant quality of life issue among patients with cancer. Reliable methods to measure changes in lymphedema are required for early detection, acute intensive treatment, and long-term management. Here, we evaluated the use of bioimpedance analysis (BIA) as a tool to measure lymphedema before and after treatment. Patients and Methods: Patients with CTRL who were admitted to a secondary university hospital between October 2017 and July 2018 for complex decongestive therapy (CDT) were eligible for this prospective cohort study. Circumferential measure (CM) and BIA were used to evaluate lymphedema at admission (initial) and before discharge (follow-up, FU). Volume was calculated from the CM using the truncated cone formula. The inter-limb ratios (ILRs) of the circumference, volume, and impedance were also calculated as the unaffected limb to affected limb. Each parameter before and after treatment and correlations between parameters also were analyzed. Results: A total of 29 patients (12 upper-and 17 lower-extremity CTRL) completed were included in this analysis. Absolute value and the ILRs of circumference, volume or impedance, and extracellular water/total body water (ECW/TBW) were significantly improved at FU (p < 0.01, p < 0.05). The initial and FU absolute values, ILRs, ECW/TBW correlated significantly with each other (p < 0.01, p < 0.05). The cutoff values of ECW/TBW for moderate and severe degree of CTRL were 0.3855 and 0.3955, respectively. The changes of ILRs between initial and FU assessments were significantly different among three groups according to lymphedema severity (p < 0.01, p < 0.05). Conclusions: BIA data correlates significantly with clinical measurement, and therefore can be a practical tool in monitoring outcome measure after lymphedema treatment. In addition, BIA is more sensitive to subtle changes in lymphedema, and therefore can be useful for the long-term maintenance of lymphedema.

“…Bioelectrical impedance technology is a simple, safe, and noninvasive method to measure lymphedema. It obtains the electrical impedance of each segment of the body by measuring the frequency current acting on the segments and analyzing the tissue composition [ 5 , 6 ]. When the current frequency is low, the current is mainly being transmitted through extracellular fluid, which allows the measurement of extracellular water (ECW); when the current frequency is high, the current is being transmitted through intracellular and extracellular fluid, which allows the measurement of total body water (TBW) [ 7 ].…”
