Purpose: Breast cancer-related lymphedema (BCRL) represents a dreaded complication of breast cancer treatment that can lead to morbidity, diminished quality of life, and psychosocial harm and is associated with increased costs of care. Increasingly, data has supported the concept of prospective BCRL surveillance coupled with early intervention to mitigate these effects., Methods: We performed a systematic review of the literature searching for published randomized and prospective data evaluating prospective BCRL surveillance with early intervention., Results: We identified 12 studies (2907 patients) including 4 randomized trials (1203 patients) and 8 prospective studies (1704 patients). Randomized data consistently demonstrate that early intervention reduces rates of progression to chronic BCRL with multiple paradigms and diagnostic modalities utilized; the strongest data comes from the randomized PREVENT trial, which demonstrated early detection with bioimpedance spectroscopy (BIS), coupled with early intervention with a compression garment applied for 12 h a day over 4 weeks, significantly reduced the rate of chronic BCRL compared to tape measurement coupled with early intervention., Conclusions: Current data support the role of prospective BCRL surveillance with early detection and intervention to reduce rates of chronic BCRL. Breast cancer patients at risk for BCRL should undergo prospective surveillance as part of survivorship. Because level 1 data demonstrate that BIS is superior to conventional tape measure, it should be included as the standard BCRL diagnostic modality unless an equally effective modality is employed., Implications for Cancer Survivors: Breast cancer survivor should undergo prospective BCRL screening with BIS., (© 2022.

Purpose: Breast cancer-related lymphedema (BCRL) represents a significant concern for patients following breast cancer treatment, and assessment for BCRL represents a key component of survivorship efforts. Growing data has demonstrated the benefits of early detection and treatment of BCRL. Traditional diagnostic modalities are less able to detect reversible subclinical BCRL while newer techniques such as bioimpedance spectroscopy (BIS) have shown the ability to detect subclinical BCRL, allowing for early intervention and low rates of chronic BCRL with level I evidence. We present updated clinical practice guidelines for BIS utilization to assess for BCRL., Methods and Results: Review of the literature identified a randomized controlled trial and other published data which form the basis for the recommendations made. The final results of the PREVENT trial, with 3-year follow-up, demonstrated an absolute reduction of 11.3% and relative reduction of 59% in chronic BCRL (through utilization of compression garment therapy) with BIS as compared to tape measurement. This is in keeping with real-world data demonstrating the effectiveness of BIS in a prospective surveillance model. For optimal outcomes patients should receive an initial pre-treatment measurement and subsequently be followed at a minimum quarterly for first 3 years then biannually for years 4-5, then annually as appropriate, consistent with previous guidelines; the target for intervention has been changed from a change in L-Dex of 10 to 6.5. The lack of pre-operative measure does not preclude inclusion in the prospective surveillance model of care., Conclusion: The updated clinical practice guidelines present a standardized approach for a prospective model of care using BIS for BCRL assessment and supported by evidence from a randomized controlled trial as well as real-world data., (© 2022.

Background: The Neoadjuvant Breast Symphony Trial (NBRST) demonstrated the 70-gene risk of distant recurrence signature, MammaPrint, and the 80-gene molecular subtyping signature, BluePrint, precisely determined preoperative pathological complete response (pCR) in breast cancer patients. We report 5-year follow-up results in addition to an exploratory analysis by age and menopausal status., Methods: The observational, prospective NBRST (NCT01479101) included 954 early-stage breast cancer patients aged 18-90 years who received neoadjuvant chemotherapy and had clinical and genomic data available. Chemosensitivity and 5-year distant metastasis-free survival (DMFS) and overall survival (OS) were assessed. In a post hoc subanalysis, results were stratified by age (≤ 50 vs. > 50 years) and menopausal status in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) tumors., Results: MammaPrint and BluePrint further classified 23% of tumors to a different subtype compared with immunohistochemistry, with more precise correspondence to pCR rates. Five-year DMFS and OS were highest in MammaPrint Low Risk, Luminal A-type and HER2-type tumors, and lowest in MammaPrint High Risk, Luminal B-type and Basal-type tumors. There was no significant difference in chemosensitivity between younger and older patients with Low-Risk (2.2% vs. 3.8%; p = 0.64) or High-Risk tumors (14.5% vs. 11.5%; p = 0.42), or within each BluePrint subtype; this was similar when stratifying by menopausal status. The 5-year outcomes were comparable by age or menopausal status for each molecular subtype., Conclusion: Intrinsic preoperative chemosensitivity and long-term outcomes were precisely determined by BluePrint and MammaPrint regardless of patient age, supporting the utility of these assays to inform treatment and surgical decisions in early-stage breast cancer., (© 2022.

Survivorship medicine is fairly new in the realm of oncology. As we broaden our focus from treatment and prevention to include survivorship there is substantial opportunity to enhance the care of the patient. Important in successful management of recovery after cancer treatment is managing the side effects of therapy and improving quality of life. This ranges from sexual dysfunction, depression to lymphedema. Guideline-based surveillance after treatment with clear communication of care plans to the patient and their providers, especially primary care, is paramount. Thoughtful pre-surgical treatment planning, which may include neoadjuvant approaches or consideration of fertility preservation, results in superior long-term patient outcomes. Understanding the importance of the teachable moment in effecting behavioral and lifestyle changes that reduce risk of recurrence is also an essential component of excellent cancer survivor patient care. We identified the following areas for focus as they represent the key areas for accreditation and patient driven needs. Development of survivorship plans, post treatment surveillance, sexuality and fertility preservation, lymphedema management and risk reduction lifestyle and behavioral changes.
