“…Inter-arm TDC ratios 1.45 and 1.30 for upper arm and forearm were used to differentiate a lymphedema patient and non-lymphedematous patient. 47 Bioimpedance spectroscopy (BIS). Extracellular fluid in the arm was measured using a sweeping frequency bioelectrical impedance meter (model SFB7, Impedimed Ltd, Australia).…”

Discrepancies between TDC and BIS techniques in assessing lymphedema are related to different measurement techniques and assessed tissue water components. Independently of selected technique-specific threshold limit, the TDC technique was more sensitive than the BIS technique in the early assessment of BCRL and demonstrated that nearly 20% of early lymphedema are only superficially localized. The results further supported the complementary role of TDC and arm volume measurements as a highly diagnostic method for early lymphedema.

“…Second, limited information is available on the optimal assessment sites. We chose all but one site based on current literature (Mayrovitz, Fasen, et al, 2017; Mayrovitz et al, 2015a,b; Weingrad and Davey 2014; Mayrovitz et al, 2008a), clinical experience, and consultation with LE therapists. Of note, the choice of the first dorsal web space may not be the ideal location to evaluate hand LTW.…”

“…Findings from these studies suggest that TDC can reliably detect inter-limb differences in LTW in women at risk for and with LE (Mayrovitz et al 2015a; Mayrovitz et al, 2014; Bakar et al, 2018; Lahtinen et al, 2015). For example, in women who had LE for less than one year following breast cancer surgery, TDC values were significantly higher in the affected versus the unaffected upper arm and forearm (Lahtinen et al, 2015).…”

“…To date, most of the studies that used TDC have assessed healthy women (Mayrovitz, Corbitt, et al 2017; Mayrovitz, Fasen, et al 2017) and upper extremity swelling in women with and without breast cancer-related LE (Mayrovitz et al, 2015a,b; Mayrovitz et al, 2014; Mayrovitz et al, 2008a,b; Lahtinen et al, 2015; Bakar et al, 2018).

“…While a small, but growing body of evidence suggests that TDC can be used to assess upper extremity LE (Mayrovitz et al, 2015a; Mayrovitz et al, 2014; Bakar et al, 2018; Lahtinen et al, 2015), limited data exist on its use for the measurement of truncal LE in breast cancer survivors. In fact, only two studies reported truncal TDC values in women after breast cancer surgery (Bakar et al, 2018; Mayrovitz et al, 2015b).…”

Given the paucity of information on local tissue water (LTW) in the upper extremity and trunk of women after breast cancer surgery, the purpose of this study was to compare tissue dielectric constant (TDC) values between the affected and unaffected sides of breast cancer survivors with and without upper extremity lymphoedema (LE). Differences in LTW were assessed using the TDC method for three sites in the upper limbs, three sites in the lateral thorax and two sites on the back. Additional measures included demographic and clinical characteristics, arm circumference and bioimpedance analysis. For the 112 survivors without LE, no differences in TDC values were found between the affected and unaffected sides for the first dorsal web space, ventral forearm and upper arm, and upper and lower back. Compared to the unaffected side, TDC values were significantly higher on the affected side for the upper, mid and lower lateral thorax. For the 78 survivors with LE, compared to the unaffected side, TDC was significantly higher on the affected side for all of the sites evaluated except the hand web space. Our findings support the use of the TDC method to detect differences in upper extremity and truncal oedema in survivors with LE following breast cancer treatment. Measurement of LTW may provide a useful method to determine truncal as well as extremity LE. The ability to detect early signs of truncal oedema may lead to pre-emptive interventions in breast cancer survivors.

Lymphedema evaluation entails multifaceted considerations for which options continue to evolve and emerge. This paper provides a critical review of the current status of diagnostic and quantitative measures for lymphedema, from traditional and novel bedside assessment tools for volumetric and fluid assessment, to advanced imaging modalities. Modalities are contrasted with regard to empirical support and feasibility of clinical implementation. The manuscript proposes a grid framework for comparing the ability of each modality to quantify specific lymphedema characteristics, including distribution, dysmorphism, tissue composition and fluid content, lymphatic anatomy and function, metaplasia, clinical symptoms, and quality of life and function. This review additionally applies a similar framework approach to consider how well assessment tools support important clinical needs, including: (1) screening, (2) diagnosis and differential diagnosis, (3) individualization of treatment, and (4) monitoring treatment response. The framework highlights which clinical needs are served by an abundance of assessment tools and identifies others that have problematically few. The framework clarifies which tools have greater or lesser empirical support. The framework is designed to assist stakeholders in selecting appropriate diagnostic and surveillance modalities, gauging levels of confidence when applying tools to specific clinical needs, elucidating overarching patterns of diagnostic and quantitative strengths and weaknesses, and informing future investigation.
