Klein I, Friger M, David MB, Shahar D. Risk factors for long-term arm morbidities following breast cancer treatments: A systematic review. Oncotarget 2023; 14:921-942. [PMID: 38039404 PMCID: PMC10691815 DOI: 10.18632/oncotarget.28539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Accepted: 11/16/2023] [Indexed: 12/03/2023] Open
Abstract
PURPOSE To examine the risk factors for arm morbidity following breast cancer treatments, taking a broad view of all types of physical morbidity, including prolonged pain, lymphedema, decreased range of motion, and functional limitations. METHODS A systematic literature review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. Studies exploring the risk factors for prolonged arm morbidity following breast cancer surgery and treatments were included. The studies were assessed independently according to pre-eligibility criteria, following data extraction and methodological quality assessment. RESULTS 1,242 articles were identified. After removing duplicates, the full texts of 1,153 articles were examined. Sixty-nine of these articles met the criteria and were included in the review. These 69 articles identified 29 risk factors for arm morbidity following treatments for breast cancer. The risk of bias was evaluated using NIH study quality assessment tools. The studies reviewed were published between 2001 and 2021 and included a total of 22,886 patients who were followed up for between three months and 10 years. CONCLUSIONS The main risk factors for long-term morbidity are removal of lymph nodes from the axilla, body mass index >30, having undergone a mastectomy, the stage of the disease, radiation therapy, chemotherapy, infection and trauma to the affected arm after surgery. An understanding of the risk factors for prolonged arm morbidity after surgery can help doctors and therapists in making personalized decisions about the need and timing of rehabilitation treatments.

Curr Oncol 2023; 30:673-680. [PMID: 36661701 PMCID: PMC9858311 DOI: 10.3390/curroncol30010052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 12/22/2022] [Accepted: 01/03/2023] [Indexed: 01/07/2023] Open
Abstract
Objective: This study aimed to compare postoperative patients with breast cancer aged ≥65 years with those aged <65 years and clarify the characteristics of postoperative patients with breast cancer aged ≥65. Methods: In total, 376 patients in whom we were able to evaluate survey items one month after surgery were included in the study. Comorbidity, including diabetes mellitus and hypertension, shoulder range of motion (ROM), upper-limb function, and psychological problems, was evaluated. Results: Hypertension and diabetes mellitus were significantly higher in patients aged ≥65 years (the elderly group) than in those aged <65 years (the non-elderly group) (p < 0.05). Preoperative shoulder flexion ROM was significantly restricted in the elderly group compared with the non-elderly group (p < 0.05). Preoperative shoulder abduction ROM was significantly restricted in the elderly group compared with the non-elderly group (p < 0.05). At one month after surgery, upper-limb function was more impaired in the non-elderly group than in the elderly group (p < 0.05). In both groups, both ROM and upper-limb function were significantly impaired one month after surgery compared with before surgery (p < 0.05). Conclusions: Postoperative patients with breast cancer aged ≥65 years should be careful about risk management and intervention during rehabilitation. Preoperative evaluation of shoulder ROM should be performed because patients aged ≥65 years have limited ROM before surgery.

Conservative interventions and clinical outcome measures used in the perioperative rehabilitation of breast cancer patients undergoing mastectomy: a scoping review. BMC Womens Health 2022; 22:343. [PMID: 35974334 PMCID: PMC9380320 DOI: 10.1186/s12905-022-01927-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Accepted: 08/09/2022] [Indexed: 11/10/2022] Open
Abstract
Background Mastectomy is the first-line treatment approach for more than 90% of breast cancer patients. The numerous physical impairments associated with this surgical procedure negatively impact the patient’s quality of life. To date, rehabilitation resources available for breast cancer patients undergoing mastectomy within the institutions affiliated to the Centre intégré universitaire de soins de santé et de services sociaux de la Mauricie-et-du-Centre-du-Québec (CIUSSS-MCQ) are lacking and do not always seem to reflect the particularities of breast cancer care pathways. The purpose of this review was to identify and describe the conservative interventions and the clinical outcome measures used in the perioperative physical rehabilitation of women with breast cancer who are awaiting or have undergone mastectomy. We also aimed to report on the barriers and facilitators to study participation and completion. Methods MEDLINE, CINAHL, and the Cochrane Library were searched from inception to January 2021, and we updated the search on July 11, 2022. We included peer-reviewed English and French literature with quantitative designs, describing conservative interventions and clinical outcome measures used within rehabilitation programs designed for women who were awaiting or had undergone mastectomy. Paired reviewers independently reviewed all citations and articles using a two-phase screening process and independently extracted the data. Results Of the 6080 articles identified, 57 met the inclusion criteria. Most interventions were multimodal, which combined exercise with patient education, manual therapy, and/or lymphatic drainage. The most frequently used objective measures of physical function were shoulder range of motion, muscle strength, and signs of lymphedema. In contrast, the primary patient-reported outcome measures were quality of life, shoulder function, and pain. Undergoing another breast surgery, death, and cancer recurrence were the most reported barriers to study completion. Conclusion This scoping review reports on the heterogeneity and wide range of conservative interventions and clinical outcome measures used in the physical rehabilitation of breast cancer patients who had undergone or were scheduled to undergo mastectomy. Tailoring interventions to breast cancer patients’ needs and promoting outpatient rehabilitation interventions appear to be better suited to the particularities of breast cancer care pathways. Further research is needed to better identify barriers and facilitators to study participation and completion.

Abstract
Lymphedema is a feared complication of cancer treatments that negatively affects survivors' quality of life. The true incidence of lymphedema is difficult to determine given its long latency period. As the number of survivors of cancer is increasing in the United States, lymphedema is poised to be a major health concern. The most noteworthy risk factor for lymphedema is comprehensive lymph node dissection. The last 2 decades have witnessed a dramatic shift in cancer treatment in an attempt to systematically de-escalate therapeutic interventions, specifically seeking to shift treatment away from routine lymph node dissection in favor of sentinel node biopsy or radiation strategies, thereby reducing the risk for lymphedema while maintaining survival outcomes. A growing body of robust evidence supports prospective screening and thereby a prospective surveillance model (PSM) for early diagnosis and intervention for the prevention and treatment of lymphedema. Finally, investigators are actively evaluating the effectiveness of contemporary surgical procedures in ameliorating the symptoms and disability of patients with lymphedema and reducing the risk of future episodes of cellulitis, with outcomes of surgery significantly better than with conservative therapy alone. In this article, we review the current data surrounding these initiatives.

Abstract
PROBLEM IDENTIFICATION Secondary lymphedema is a chronic condition that may result from cancer-related treatments. Evidence is emerging on prospective surveillance and risk reduction. LITERATURE SEARCH Databases were systematically searched through April 1, 2019, for comparative studies evaluating interventions aiming to prevent lymphedema in patients with cancer. DATA EVALUATION A random-effects model was used to perform meta-analysis, when appropriate. SYNTHESIS A total of 26 studies (4,095 patients) were included, with 23 providing data sufficient for meta-analysis. Surveillance programs increased the likelihood of detecting lymphedema. Physiotherapy, exercise programs, and delayed exercise reduced the incidence of lymphedema. IMPLICATIONS FOR RESEARCH Future research should standardize (a) evidence-based interventions to reduce the development of lymphedema and increase the likelihood of early detection and (b) outcome measures to build a body of evidence that leads to practice change.

Abstract
OBJECTIVES Breast cancer survivors experience a wide spectrum of physical sequelae from cancer treatment. National and international guidelines recommend that rehabilitation is offered from the point of diagnosis. However, there is a lack of data on the translation of these recommendations into clinical care. The objective of this study was to explore the experiences of breast cancer survivors, rehabilitation professionals and breast surgeons on current rehabilitation services including preferences for care delivery, specific ways to promote early detection and timely management of upper body issues and attitudes towards self-managed surveillance and rehabilitation. DESIGN Qualitative focus groups. Breast cancer survivors completed a questionnaire about rehabilitation services received and experience of upper body issues. These quantitative data were collected to provide context for the qualitative data and increase transferability. Transcripts were analysed using content analysis. SETTING Five geographically distinct health authorities in British Columbia, Canada. PARTICIPANTS Eleven focus groups were conducted with 35 breast cancer survivors, 29 rehabilitation professionals and 5 breast surgeons. RESULTS Three categories captured participants' concern and wish for improved care: (1) cut the cancer out and goodbye; (2) you have to look out for yourself and (3) in a perfect world. All breast cancer survivors reported chronic upper body issues (mean 4.5 unique issues). Breast cancer survivors expressed worry and uncertainty in their solo management of the rehabilitation. The current services were reported to not enable early detection and timely management. Suggestions included reorganising the timing of patient education and improving the quality of and access to rehabilitation services by elevating the knowledge among healthcare professionals and providing multimodal self-management resources. CONCLUSIONS The results revealed a gap between oncology guidelines and the current clinical reality. The rehabilitation services were reported in need of revamping to increase equity of care. Multiple upper body issues were reported by many breast cancer survivors.

Abstract
PURPOSE Breast cancer survivorship is common (90% of women survive 5 or more years), but many women are not able to return to full function and well-being after treatment due to functional limitations, persistent pain, and inability to perform daily activities. Since each surgical reconstructive option (e.g., autologous tissue flaps versus implants) can impact shoulder and arm function differently, it is important to understand how shoulder and upper limb strength, mobility, and function are influenced by the type of surgical intervention. Efforts can then focus on prehabiliation strategies to prevent the onset of limitations and on developing rehabilitation protocols that directly target shortcomings. METHODS The current paper presents a review summarizing how shoulder and upper limb function may be affected by surgical mastectomy and breast reconstruction. RESULTS Mastectomy and breast reconstruction with implants or autologous tissues present different functional outcomes for patients. Each surgical procedure is associated with unique sequelae derived from the tissues and procedures associated with each surgery. Characterizing the specific functional outcomes associated with each surgical approach will promote the development of targeted rehabilitation strategies that can be implemented into a multidisciplinary treatment planning pathway for breast cancer patients. CONCLUSIONS Surgical treatments for breast cancer, including mastectomy and breast reconstruction, can have negative effects. Focused efforts are needed to better understand treatment-specific effects so that targeted rehabilitation can be developed to improve patient function, QoL, and ability to return to work and life activities post-breast cancer.

Abstract
BACKGROUND Lymphoedema is a chronic condition that has significant detrimental impact on patients' quality of life. Secondary lymphoedema often results from anti-tumour treatment, in contrast to primary lymphoedema which is the result of genetic abnormalities that leads to an abnormal development of the lymphatic system. OBJECTIVE To describe and compare the experience of individuals with primary and secondary lymphoedema. METHODS A total of 19 patients (mean ± standard deviation age: 56.7 ± 16.2 years), 8 with primary and 11 with secondary lymphoedema, participated in this qualitative phenomenological study. Purposeful sampling method was applied. We recruited participants from specialised lymphoedema units of two physical therapy clinics and the Lymphoedema Patient Association in Spain. Data collection methods included unstructured and semi-structured interviews. An inductive thematic analysis was used. RESULTS The findings suggest differences between the experience of living with primary or secondary lymphoedema. Also, those with lower extremity lymphoedema have more pain, fatigue, and functional limitations. Three primary themes emerged: "Emotional challenge", "Adapting your life to a new situation," and "lymphoedema management". CONCLUSIONS The experience of living with lymphoedema involves aspects of fear, suffering, coping, and management of the disease and differs between secondary and primary causes. However, it seems to be more dependent on its location than its cause.

Abstract
PURPOSE Chronic upper extremity disability (UED) is common after breast cancer treatment but under-identified and under-treated. Although UED has been linked to quality of life (QoL), the role of UED as mediator between contemporary treatment practices and QoL has not been quantified. This investigation describes UED in a contemporary sample of breast cancer patients and examines its relationship with personal and treatment factors and QoL. METHODS Eight hundred and thirty-three women diagnosed at eight medical institutions during 2013-2014 with microscopically confirmed ductal carcinoma in situ or invasive stage I-III breast cancer were surveyed an average of 22 months after diagnosis. UED was measured with a modified QuickDASH and QoL with the FACT-B. The questionnaire also collected treatments, sociodemographic information, comorbidity, body mass index, and a 3-item health literacy screener. RESULTS Women who received post-mastectomy radiation and chemotherapy experienced significantly worse UED and QoL. Women who had lower income, lower health literacy and prior diabetes, arthritis or shoulder diagnoses had worse UED. Patients with worse UED reported significantly worse QoL. Income and health literacy were independently associated with QoL after adjustment for UED but treatment and prior conditions were not, indicating mediation by UED. UED mediated 52-79% of the effect of mastectomy-based treatments on QoL as compared with unilateral mastectomy without radiation. UED and QoL did not differ by type of axillary surgery or post-mastectomy reconstruction. CONCLUSIONS A large portion of treatment effect on QoL is mediated by UED. Rehabilitation practices that prevent and alleviate UED are likely to improve QoL for breast cancer survivors.

Three-dimensional scapular kinematics, shoulder outcome measures and quality of life following treatment for breast cancer - A case control study. Musculoskelet Sci Pract 2019; 40:72-79. [PMID: 30711913 DOI: 10.1016/j.msksp.2019.01.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 01/14/2019] [Accepted: 01/23/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND There are no conclusive results concerning changes in scapular kinematics associated with upper limb dysfunctions after breast cancer surgery. OBJECTIVE To compare the three-dimensional (3-D) scapular kinematics during elevation of the arm between women after breast cancer surgery and controls. Shoulder range of motion (ROM), muscle strength, pain intensity, upper limb function, and quality of life were also assessed. METHODS Forty-two women were assigned to two groups (surgery group, n = 21; control group, n = 21). 3-D scapular kinematics was collected during elevation of the arm in the scapular plane. ROM was assessed using a digital inclinometer, muscle strength using a manual dynamometer, pain with the Visual Analogue Scale (VAS), upper limb function with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and quality of life with the 36-item Short-Form Health Survey (SF36). RESULTS The surgery group presented decreased scapular upward rotation at 120° of arm elevation in the scapular plane (p < .05; d = -0.88), decreased shoulder external rotation ROM and strength of shoulder abduction and external rotation when the affected side was compared to the non-affected side and control group. Moreover, the surgery group also reported higher pain, increased upper limb disability and poorer quality of life compared with healthy controls. CONCLUSION Scapular upward rotation seems to be decreased at 120° of arm elevation in women following breast cancer surgery. In addition, shoulder external rotation ROM, abduction strength, external rotation strength, function, and quality of life are also impaired in these women. They also experienced pain during the studied movements.

Abstract
Prehabilitation benefits among patients undergoing various oncological surgeries have been demonstrated. However, the effects of presurgical exercise and fitness on postoperative ipsilateral upper extremity recovery outcomes in patients with breast cancer surgery are less evident. A systematic review was performed to assess the effects of preoperative exercise and fitness on postmastectomy recovery. Systematic literature search was performed in 12 electronic databases. Study eligibility was accessed using the PICOS (Participants, Interventions, Comparison, Outcome and Study Design) criteria. Six eligible studies were found: three cohort-control and three prospective observational studies. One randomized-controlled trial showed that prehabilitation was beneficial in shoulder range of motion (ROM) and upper extremity functional recovery. One cohort-control study demonstrated that preoperative exercises reduced postoperative pain without increasing the risk of developing a seroma. A prospective cohort study showed that preoperatively active individuals had a significantly better chance of feeling recovered physically at 3 weeks after surgery. Baseline ipsilateral grip strength, shoulder flexion, and abduction ROM were reliable predictors of shoulder flexion and abduction ROM and grip strength improvements at 1 month following breast cancer surgery. One study showed that preoperative conditioning alone without postoperative rehabilitation was insufficient to aid recovery. Implementing exercise program and optimizing preoperative fitness, especially shoulder ROM, before breast cancer surgery in conjunction with individualized rehabilitation program may benefit postmastectomy ipsilateral upper extremity recovery.

Lymphedema symptoms and limb measurement changes in breast cancer survivors treated with neoadjuvant chemotherapy and axillary dissection: results of American College of Surgeons Oncology Group (ACOSOG) Z1071 (Alliance) substudy. Support Care Cancer 2018; 27:495-503. [PMID: 29980907 DOI: 10.1007/s00520-018-4334-7] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2017] [Accepted: 06/26/2018] [Indexed: 01/08/2023]
Abstract
PURPOSE Lymphedema is a potential complication of breast cancer treatment. This longitudinal substudy aimed to prospectively assess arm measurements and symptoms following neoadjuvant chemotherapy and axillary dissection in the ACOSOG/Alliance Z1071 trial to characterize the optimal approach to define lymphedema. METHODS Z1071 enrolled patients with cT0-4, N1-2, M0 disease treated with neoadjuvant chemotherapy. All patients underwent axillary dissection. Bilateral limb volumes, circumferences, and related symptoms were assessed pre-surgery, 1-2 weeks post-surgery, and semiannually for 36 months. Lymphedema definitions included volume increase ≥ 10% or limb circumference increase ≥ 2 cm. Symptoms were assessed by the Lymphedema Breast Cancer Questionnaire. RESULTS In 488 evaluable patients, lymphedema incidence at 3 years by ≥ 10%-volume-increase was 60.3% (95% CI 55.0-66.2%) and by ≥ 2 cm-circumference increase was 75.4% (95% CI 70.8-80.2%). Symptoms of arm swelling and heaviness decreased from post-surgery for the first 18 months and then were relatively stable. The 3-year cumulative incidence of arm swelling and heaviness was 26.0% (95% CI 21.7-31.1%) and 30.9% (95% CI 26.3-36.3%), respectively. There was limited agreement between the two measurements (kappa 0.27) and between symptoms and measurements (kappa coefficients ranging from 0.05-0.09). CONCLUSIONS Lymphedema incidence by limb volume and circumference gradually increased over 36 months post-surgery, whereas lymphedema symptoms were much lower. These findings underscore the importance of prospective surveillance and evaluation of both limb measurements and symptom assessment. Lymphedema incidence rates varied by definition. We recommend that ≥ 10% volume change criterion be used for lymphedema evaluation for referral for specialist care. TRIAL REGISTRATION NCT00881361.

Abstract
OBJECTIVE To evaluate prospective surveillance and targeted physiotherapy (PSTP) compared to education (EDU) on the prevalence of arm morbidity and describe the associated program cost. DESIGN Pilot randomized single-blinded controlled trial. SETTING Urban with assessments and treatment delivered in hospitals. PARTICIPANTS Women scheduled for breast cancer surgery. INTERVENTIONS Participants were randomly assigned (1:1) to PSTP ( n = 21) or EDU ( n = 20) and assessed presurgery and 12 months postsurgery. All participants received usual care, namely, preoperative education and provision of an education booklet with postsurgical exercises. The PSTP group was monitored for arm morbidity every three months and referred for physiotherapy if arm morbidity was identified. The EDU group received three education sessions on nutrition, stress and fatigue management. MAIN OUTCOME MEASURES Arm morbidity was based on changes in the surgical arm(s) from presurgery in four domains: (1) shoulder range of motion, (2) strength, (3) volume, and (4) upper body function. Complex arm morbidity indicated ≥2 domains impaired. Second, the cost of the PSTP program was described. RESULTS At 12 months, 18 (49%) participants (10 PSTP and 8 EDU) had arm morbidity, with EDU participants presenting more complex arm morbidity compared to PSTP participants. PSTP participants attended 4.4 of 5 assessments with 90% retention. The PSTP program cost was $150 covered by the Health Care Provider and the Patient Out-of-Pocket Travel cost was CAN$40. CONCLUSION Our results suggest that PSTP is feasible among women with breast cancer for early identification of arm morbidity. A larger study is needed to determine the cost and effectiveness benefits.

Abstract
PURPOSE The study aim was to develop a mobile application (app) supported by user preferences to optimise self-management of arm and shoulder exercises for upper-limb dysfunction (ULD) after breast cancer treatment. METHODS Focus groups with breast cancer patients were held to identify user needs and requirements. Behaviour change techniques were explored by researchers and discussed during the focus groups. Concepts for content were identified by thematic analysis. A rapid review was conducted to inform the exercise programme. Preliminary testing was carried out to obtain user feedback from breast cancer patients who used the app for 8 weeks post surgery. RESULTS Breast cancer patients' experiences with ULD and exercise advice and routines varied widely. They identified and prioritised several app features: tailored information, video demonstrations of the exercises, push notifications, and tracking and progress features. An evidence-based programme was developed with a physiotherapist with progressive exercises for passive and active mobilisation, stretching and strengthening. The exercise demonstration videos were filmed with a breast cancer patient. Early user testing demonstrated ease of use, and clear and motivating app content. CONCLUSIONS bWell, a novel app for arm and shoulder exercises, was developed by breast cancer patients, health care professionals and academics. Further research is warranted to confirm its clinical effectiveness. IMPLICATIONS FOR CANCER SURVIVORS Mobile health has great potential to provide patients with information specific to their needs. bWell is a promising way to support breast cancer patients with exercise routines after treatment and may improve future self-management of clinical care.

Differences in limb volume trajectories after breast cancer treatment. J Cancer Surviv 2015; 10:772-82. [PMID: 26678895 DOI: 10.1007/s11764-015-0507-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2015] [Accepted: 12/06/2015] [Indexed: 01/20/2023]
Abstract
PURPOSE Approximately 20 % of patients develop lymphedema (LE) following breast cancer (BC) surgery. An evaluation of distinct trajectories of volume change may improve our ability to diagnose LE sooner. The purposes of this study were to identify subgroups of women with distinct trajectories of limb volume changes following BC surgery and to evaluate for phenotypic differences among these classes. METHODS In this prospective longitudinal study, 380 women were enrolled prior to unilateral BC surgery. Upper limb bioimpedance was measured preoperatively and serially for 1 year postoperatively. Resistance ratios (RRs) were calculated. A RR of >1 indicates affected limb volume > unaffected limb volume. Latent class growth analysis (LCGA) was used to identify classes of women with distinct postoperative RR trajectories. Differences among classes were evaluated using analyses of variance and chi-square analyses. RESULTS Three distinct classes were identified as follows: RR <0.95 (37.9 %), RR ~1.00 (46.8 %), and RR >1.05 (15.3 %). Patients in the RR >1.05 class were more likely to have diabetes (p = 0.036), were more likely to have BC on their dominant side (p < 0.001), had higher RR ratios at the preoperative and 1-month assessments (p < 0.001), and were more likely to be diagnosed with LE (p < 0.001). CONCLUSIONS LCGA is a useful analytic technique to identify subgroups of women who may be at higher risk for the development of LE, based on trajectories of limb volume change after BC surgery. IMPLICATIONS FOR CANCER SURVIVORS Assessment of preoperative and 1-month bioimpedance RRs may allow for the earlier identification of patients who are at higher risk for the development of LE.

Abstract
The potential impact of breast cancer-related lymphedema (LE) is quite extensive, yet it often remains under-diagnosed until the later stages. This project examines the effectiveness of prospective surveillance in post-surgical breast cancer patients. A retrospective analysis of 49 out of 100 patients enrolled in a longitudinal prospective study at a Midwestern breast center evaluates: (1) time required for completion of bilateral limb measurements and Lymphedema Breast Cancer Questionnaire (LBCQ); (2) referral to LE management with limb volume increase (LVI) and/or LBCQ symptoms; and (3) cost of LE management at lower LVI (≥5%–≤10%) versus traditional (≥10%). Findings revealed a visit timeframe mean of 40.3 min (range = 25–60); 43.6% of visits were ≤30-min timeframe. Visit and measurement times decreased as clinic staff gained measurement experience; measurement time mean was 17.9 min (range = 16.9–18.9). LBCQ symptoms and LVI were significantly (p < 0.001) correlated to LE referral; six of the nine patients referred (67%) displayed both LBCQ symptoms/LVI. Visits with no symptoms reported did not result in referral, demonstrating the importance of using both indicators when assessing early LE. Lower threshold referral provides compelling evidence of potential cost savings over traditional threshold referral with reported costs of: $3755.00 and $6353.00, respectively (40.9% savings).

Abstract
CONTEXT Approximately 30% of the women report pain in the affected breast before breast cancer surgery. OBJECTIVES The purpose of this secondary analysis of our prospective study was to determine how women who experienced both preoperative and persistent postsurgical breast pain (n=107) differed from women who did not report preoperative breast pain and did (n=158) or did not (n=122) experience persistent postsurgical breast pain. METHODS Differences in demographic and clinical characteristics were evaluated. Linear mixed effects (LME) modeling was used to evaluate for group differences in symptom severity, function, sensation, and quality of life (QOL) over time. RESULTS Between-group differences in demographic and clinical characteristics as well as trajectories of shoulder function and QOL were identified. Women with both preoperative and persistent postsurgical breast pain were younger; were more likely to report swelling, strange sensations, hardness, and numbness in the affected breast before surgery; and were more likely to have reconstruction at the time of surgery. Women with both preoperative and persistent postsurgical breast pain had more biopsies in the prior year, more lymph nodes removed, and reported more severe acute postsurgical pain than women without preoperative breast pain. The LME modeling revealed significant group effects for most outcomes evaluated. Over the six months of the study, women with both preoperative and persistent postsurgical pain had persistently poorer shoulder flexion and physical well-being than women without preoperative breast pain. CONCLUSION Investigations of the etiology and molecular mechanisms of preoperative breast pain, as well as interventions for this high-risk group, are needed.
