Fu, Mei R; Axelrod, Deborah; Guth, Amber A; Rampertaap, Kavita; El-Shammaa, Nardin; Hiotis, Karen; Scagliola, Joan; Yu, Gary; Wang, Yao
BACKGROUND: Many women suffer from daily distressing symptoms related to lymphedema following breast cancer treatment. Lymphedema, an abnormal accumulation of lymph fluid in the ipsilateral body area or upper limb, remains an ongoing major health problem affecting more than 40% of 3.1 million breast cancer survivors in the United States. Patient-centered care related to lymphedema symptom management is often inadequately addressed in clinical research and practice. mHealth plays a significant role in improving self-care, patient-clinician communication, and access to health information. The-Optimal-Lymph-Flow health IT system (TOLF) is a patient-centered, web-and-mobile-based educational and behavioral mHealth interventions focusing on safe, innovative, and pragmatic electronic assessment and self-care strategies for lymphedema symptom management. The purpose of this paper is to describe the development and test of TOLF system. METHODS: The development of TOLF was guided by the Model of Self-Care for Lymphedema Symptom Management and designed based on principles fostering accessibility, convenience, and efficiency of mHealth system to enhance training and motivating assessment of and self-care for lymphedema symptoms. Test of TOLF was accomplished by conducting a psychometric study to evaluate reliability, validity, and efficiency of the electronic version of Breast Cancer and Lymphedema Symptom Experience Index (BCLE-SEI), a usability testing and a pilot feasibility testing of mHealth self-care interventions. RESULTS: Findings from the psychometric study with 355 breast cancer survivors demonstrated high internal consistency of the electronic version of the instrument: a Cronbach's alpha coefficient of 0.959 for the total scale, 0.919 for symptom occurrence, and 0.946 for symptom distress. Discriminant validity of the instrument was supported by a significant difference in symptom occurrence (z=-6.938, P<0.000), symptom distress (z=-5.894, P<0.000), and total scale (z=-6.547, P<0.000) between breast cancer survivors with lymphedema and those without it. Findings of usability testing showed that breast cancer survivors were very satisfied with the mHealth self-care interventions: 90% rated the system having no usability problems; 10% noted minor cosmetic problems: spelling errors or text font size. The majority of participants 96.6% strongly agreed that the system was easy to use and effective in helping to learn about lymphedema, symptoms and self-care strategies. Feasibility testing demonstrated that a 12-week one group intervention using TOLF had significantly positive effects on less pain (P=0.031), less soreness (P=0.021), less aching (P=0.024), less tenderness (P=0.039), fewer numbers of lymphedema symptoms (P=0.003), and improved symptom distress (P=0.000) at 12 weeks after intervention. Themes from the qualitative data included empowerment, high quality information, loving avatar simulation videos, easy accessibility, and user-friendliness. CONCLUSIONS: TOLF system using the electronic version of the instrument is able to assess patients' lymphedema symptoms with high reliability and validity. TOLF system is also able to deliver self-care interventions to enhance self-care strategies for lymphedema symptom management.

Prospective Randomized Trial of Prone Accelerated Intensity Modulated Breast Radiation Therapy With a Daily Versus Weekly Boost to the Tumor Bed

Cooper, Benjamin T; Formenti-Ujlaki, George F; Li, Xiaochun; Shin, Samuel M; Fenton-Kerimian, Maria; Guth, Amber; Roses, Daniel F; Hitchen, Christine J; Rosenstein, Barry S; Dewyngaert, J Keith; Goldberg, Judith D; Formenti, Silvia C
PURPOSE: To report the results of a prospective randomized trial comparing a daily versus weekly boost to the tumor cavity during the course of accelerated radiation to the breast with patients in the prone position. METHODS AND MATERIALS: From 2009 to 2012, 400 patients with stage 0 to II breast cancer who had undergone segmental mastectomy participated in an institutional review board-approved trial testing prone breast radiation therapy to 40.5 Gy in 15 fractions 5 d/wk to the whole breast, after randomization to a concomitant daily boost to the tumor bed of 0.5 Gy, or a weekly boost of 2 Gy, on Friday. The present noninferiority trial tested the primary hypothesis that a weekly boost produced no more acute toxicity than did a daily boost. The recurrence-free survival was estimated for both treatment arms using the Kaplan-Meier method; the relative risk of recurrence or death was estimated, and the 2 arms were compared using the log-rank test. RESULTS: At a median follow-up period of 45 months, no deaths related to breast cancer had occurred. The weekly boost regimen produced no more grade >/=2 acute toxicity than did the daily boost regimen (8.1% vs 10.4%; noninferiority Z = -2.52; P=.006). No statistically significant difference was found in the cumulative incidence of long-term fibrosis or telangiectasia of grade >/=2 between the 2 arms (log-rank P=.923). Two local and two distant recurrences developed in the daily treatment arm and three local and one distant developed in the weekly arm. The 4-year recurrence-free survival rate was not different between the 2 treatment arms (98% for both arms). CONCLUSIONS: A tumor bed boost delivered either daily or weekly was tolerated similarly during accelerated prone breast radiation therapy, with excellent control of disease and comparable cosmetic results.

DCIS is a noninvasive cancer, not a risk factor for breast cancer [Meeting Abstract]

Guth, A; Montes, J; Schnabel, F; Chun, J; Schwartz, S; Kamen, E; Shapiro, R; Axelrod, D
Introduction: Ductal carcinoma in situ (DCIS) and invasive breast cancer have long been viewed as representing two points on the spectrum of one disease. A recent study published by Narod et al. found that women diagnosed with DCIS who developed an invasive recurrence were 18.1 times more likely to die of breast cancer than women who did not. In light of this controversial topic, we investigated DCIS in a contemporary cohort of newly diagnosed women at our institution spanning a five year period. Methods: The institutional Breast Cancer Database was queried for all women with newly diagnosed breast cancer from 2010-2015. Variables included age, race, body mass index (BMI), risk factors, tumor characteristics and outcomes. Statistical analyses included Pearson's Chi Square and Fisher's Exact Tests. Results: Out of a total of 2190 patients, 475 (22%) had pure DCIS while 1715 (78%) had invasive cancer. The median follow up was 3 years. The median age was 59 years (range 22-95). Of the patients with invasive cancer, 36 (2%) had any recurrence. Similarly, of the patients with DCIS, 9 (2%) developed recurrent disease (ipsilateral or contralateral), with 4 patients diagnosed with invasive recurrence (44%). Of the 36 recurrences in patients with invasive cancer, 33% presented with chest wall or distant metastasis. Patients with pure DCIS had a slightly higher proportion of African Americans and Hispanics (11% v. 8%) and higher proportion of women with BMI>30 who developed an invasive recurrence (78% v. 50%). All recurrences in the pure DCIS cohort were detected by routine screening surveillance, with a majority detected by mammography (89%). Conclusions: Within a relatively short follow up period, we found that the rates of in-breast recurrences were the same in women with pure DCIS compared to women with invasive breast cancer. Also, 44% of women developed invasive breast cancer recurrence after an initial DCIS diagnosis, potentially altering their long term survival. These findings suggest that women with all breast cancers, including DCIS, requires intensive surveillance after initial treatment, as consequences of delayed diagnosis may impact on their long term survival

Cost Analysis of Intraoperative Subareolar Frozen Section During Nipple-Sparing Mastectomy

Alperovich, Michael; Reis, Scott M; Choi, Mihye; Karp, Nolan S; Frey, Jordan D; Chang, Jessica B; Axelrod, Deborah M; Shapiro, Richard L; Guth, Amber A
BACKGROUND: Permanent paraffin subareolar biopsy during nipple-sparing mastectomy (NSM) tests for occult cancer at the nipple-areolar complex. Intraoperative subareolar frozen section can provide earlier detection intraoperatively. Cost analysis for intraoperative subareolar frozen section has never been performed. METHODS: NSM cases from 2006-2013 were reviewed. Patient records including financial charges were analyzed. RESULTS: Of 480 subareolar biopsies for NSM from 2006-2013, 21 were abnormal (4.4 %). A total of 307 of the subareolar biopsies included intraoperative frozen section. Of the 307, 12 (3.9 %) were abnormal with 7 of 12 detected on intraoperative frozen section. The median baseline charge for an intraoperative subareolar frozen section was $309 for an estimated total cost of $94,863 in 307 breasts. The median baseline charge for interval operative resection of a nipple-areolar complex following an abnormal subareolar pathology result was $11,021. Intraoperative subareolar biopsy avoided an estimated six return trips to the operating room for savings of $66,126. At our institution, routine use of intraoperative frozen section resulted in an additional $28,737 in healthcare charges or $95 per breast. CONCLUSIONS: We present the first cost analysis to evaluate intraoperative subareolar frozen section in NSM. This practice obviated an estimated six return trips to the operating room. With our institutional frequency of abnormal subareolar pathology, intraoperative frozen sections resulted in a marginal increased charge per mastectomy.

A Web- and Mobile-Based Intervention for Women Treated for Breast Cancer to Manage Chronic Pain and Symptoms Related to Lymphedema: Randomized Clinical Trial Rationale and Protocol

Fu, Mei Rosemary; Axelrod, Deborah; Guth, Amber; Scagliola, Joan; Rampertaap, Kavita; El-Shammaa, Nardin; Fletcher, Jason; Zhang, Yan; Qiu, Jeanna M; Schnabel, Freya; Hiotis, Karen; Wang, Yao; D'Eramo Melkus, Gail
BACKGROUND: Despite current advances in cancer treatment, many breast cancer survivors still face long-term post-operative challenges as a result of suffering from daily pain and other distressing symptoms related to lymphedema, ie, abnormal accumulation of lymph fluid in the ipsilateral upper limb or body. Grounded in research-driven behavioral strategies, The-Optimal-Lymph-Flow is a unique Web- and mobile-based system focusing on self-care strategies to empower, rather than inhibit, how breast cancer survivors manage daily pain and symptoms. It features a set of safe, feasible, and easily-integrated-into-daily-routine exercises to promote lymph flow and drainage, as well as guidance to maintain an optimal body mass index (BMI). OBJECTIVE: To conduct a randomized clinical trial (RCT) to evaluate the efficacy of the Web- and mobile-based The-Optimal-Lymph-Flow system for managing chronic pain and symptoms related to lymphedema. The primary outcome includes pain reduction, and the secondary outcomes focus on symptom relief, limb volume difference by infra-red perometer, BMI, and quality of life (QOL) related to pain. We hypothesize that participants in the intervention group will have improved pain and symptom experiences, limb volume difference, body mass index, and QOL. METHODS: A parallel RCT with a control-experimental, pre- and post-test, repeated-measures design is used in this study. A total of 120 patients will be randomized according to the occurrence of pain. Participants will be recruited face-to-face at the point of care during clinical visits. Participants in the intervention group will receive the Web- and mobile-based The-Optimal-Lymph-Flow intervention and will have access to and learn about the program during the first in-person research visit. Participants in the control group will receive the Web- and mobile-based Arm Precaution program and will have access to and learn about the program during the first in-person research visit. Participants will be encouraged to enhance their learning by accessing the program and following the daily exercises during the study period. Participants will have monthly online self-report of pain and symptoms at 4 and 8 weeks post-intervention. During the two in-person research visits prior to and 12 weeks post-intervention, participants will be measured for limb volume difference, BMI, and complete self-report of pain, symptoms, self-care behaviors, and QOL. RESULTS: This trial is currently open for recruitment. The anticipated completion date for the study is July 2017. The primary endpoint for the study is absence or reduction of pain reported by the participants at week 12 post-intervention. CONCLUSIONS: The-Optimal-Lymph-Flow is a unique Web- and mobile-based self-care and patient-reported outcome system designed to effectively help women treated for breast cancer manage daily pain and symptoms related to lymphedema. Patients learn self-care strategies from a Web- and mobile-based program and track their symptoms. The RCT will directly benefit all women treated for breast cancer who suffer from or at risk for pain and symptoms related to lymph fluid accumulation.

Nipple-sparing Mastectomy and Sub-areolar Biopsy: To Freeze or not to Freeze? Evaluating the Role of Sub-areolar Intraoperative Frozen Section

Alperovich, Michael; Choi, Mihye; Karp, Nolan S; Singh, Baljit; Ayo, Diego; Frey, Jordan D; Roses, Daniel F; Schnabel, Freya R; Axelrod, Deborah M; Shapiro, Richard L; Guth, Amber A
Use of nipple-sparing mastectomy (NSM) for risk-reduction and therapeutic breast cancer resection is growing. The role for intraoperative frozen section of the nipple-areolar complex remains controversial. Records of patients undergoing NSM at our institution from 2006 to 2013 were reviewed. Records from 501 nipple-sparing mastectomies were reviewed (216 therapeutic, 285 prophylactic). Of the 480 breasts with sub-areolar biopsies, 307 had intraoperative frozen sections and 173 were evaluated with permanent paraffin section only. Among the 307 intraoperative frozen sections, 12 biopsies were positive on permanent paraffin section (3.9% or 12/307). Of the 12 positive permanent biopsies, five were false negative and the remaining seven concordant intraoperatively. Sensitivity and specificity of sub-areolar frozen section were 0.58 and 1, respectively. Positive sub-areolar biopsies consisted primarily of ductal carcinoma in situ (62% or 13/21). The nipples or nipple-areolar complex were resected in a separate procedure following mastectomy (10/21), intraoperatively following frozen section results (7/21) or during second-stage breast reconstruction (3/21; 1 additional scheduled). Only 30% (6/20) of resected specimens had abnormal residual pathology. Intraoperative frozen section is highly specific and moderately sensitive for the detection of positive sub-areolar biopsies in NSM. Its use can help guide intraoperative reconstructive planning. The presence of positive sub-areolar biopsies in both contralateral and high-risk prophylactic mastectomy specimens emphasizes the need to perform sub-areolar biopsies in all nipple-sparing mastectomies.

Oncologic outcomes after nipple-sparing mastectomy: A single-institution experience

Frey, Jordan D; Alperovich, Michael; Kim, Jennifer Chun; Axelrod, Deborah M; Shapiro, Richard L; Choi, Mihye; Schnabel, Freya R; Karp, Nolan S; Guth, Amber A
INTRODUCTION: Long-term oncologic outcomes in nipple-sparing mastectomy (NSM) continue to be defined. Rates of locoregional recurrence for skin-sparing mastectomy (SSM) and NSM in the literature range from 0% to 14.3%. We investigated the outcomes of NSM at our institution. METHODS: Patients undergoing NSM at our institution from 2006 to 2014 were identified and outcomes were analyzed. RESULTS: From 2006 to 2014, 319 patients (555 breasts) underwent NSM. One-hundered and fourty-one patients (237 breasts) had long-term follow-up available. Average patient age and BMI were 47.78 and 24.63. Eighty-four percent of patients underwent mastectomy primarily for a therapeutic indication. Average tumor size was 1.50 cm with the most common histologic type being invasive ductal carcinoma (62.7%) followed by DCIS (23.7%). Average patient follow-up was 30.73 months. There was one (0.8%) incidence of ipsilateral chest-wall recurrence. There were 0.37 complications per patient. CONCLUSIONS: We examined our institutional outcomes with NSM and found a locoregional recurrence rate of 0.8% with no nipple-areolar complex recurrence. This rate is lower than published rates for both NSM and SSM. J. Surg. Oncol. (c) 2015 Wiley Periodicals, Inc.

Oncologic outcomes after nipple-sparing mastectomy: A single-institution experience [Meeting Abstract]

Guth, A A; Frey, J D; Alperovich, M; Kim, J C; Axelrod, D M; Shapiro, R L; Choi, M; Karp, N S; Schnabel, F R
Introduction: Nipple-sparing mastectomy (NSM) is the latest advancement in the treatment of breast cancer. Long-term oncologic outcomes in nipple-sparing mastectomy (NSM) continue to be defined. Rates of locoregional recurrence for skin-sparing mastectomy (SSM) and NSM in the literature range from 0 to 14.3%. We investigated the outcomes of NSM at our institution. Methods: Patients undergoing NSM at our institution from 2006 to 2014 were identified. Patient demographics, tumor characteristics, and outcomes were collected. Locoregional recurrence was compared to previously published NSM and SSM results compiled from 14 and 11 studies in the literature. Institutional review board approval was obtained prior to the initiation of this study. Results: From 2006 to 2014, 319 patients (555 breasts) underwent NSM. 149 patients (248 breasts) had long-term follow-up available. Average patient age and BMI were 47.4 and 24.28. Eighty-five percent of patients underwent mastectomy primarily for a therapeutic indication. Average tumor size was 1.41 centimeters with the most common histologic type being invasive ductal carcinoma (66.7%) followed by DCIS (23.8%). Nodal disease was present in 14.8% of patients. Average patient follow-up was 30.72 months. There was one (0.7%) incidence of ipsilateral chest-wall recurrence in a 44 year-old (p<0.0001, compared to aggregate NSM and SSM data). There were 0.36 complications per patient. There were 3 incidences of nipple-areola complex (NAC) necrosis: 2 partial thickness necrosis and 1 full thickness necrosis. (Table Presented) Conclusions: We examined our institutional outcomes with NSM and found a locoregional recurrence rate of 0.7% with no nipple-areolar complex recurrence. This rate is significantly lower than aggregate published rates for both NSM and SSM
