RESUMO

OBJECTIVE: To create a blueprint for surgical department leaders, academic institutions, and funding agencies to optimally support surgeon-scientists. BACKGROUND: Scientific contributions by surgeons have been transformative across many medical disciplines. Surgeon-scientists provide a distinct approach and mindset toward key scientific questions. However, lack of institutional support, pressure for increased clinical productivity, and growing administrative burden are major challenges for the surgeon-scientist, as is the time-consuming nature of surgical training and practice. METHODS: An American Surgical Association Research Sustainability Task Force was created to outline a blueprint for sustainable science in surgery. Leaders from top NIH-sponsored departments of surgery engaged in video and in-person meetings between January and April 2023. A strength, weakness, opportunities, threats analysis was performed, and workgroups focused on the roles of surgeons, the department and institutions, and funding agencies. RESULTS: Taskforce recommendations: (1) SURGEONS: Growth mindset : identifying research focus, long-term planning, patience/tenacity, team science, collaborations with disparate experts; Skill set : align skills and research, fill critical skill gaps, develop team leadership skills; DEPARTMENT OF SURGERY (DOS): (2) MENTORSHIP: Chair : mentor-mentee matching/regular meetings/accountability, review of junior faculty progress, mentorship training requirement, recognition of mentorship (eg, relative value unit equivalent, awards; Mentor: dedicated time, relevant scientific expertise, extramural funding, experience and/or trained as mentor, trusted advisor; Mentee : enthusiastic/eager, proactive, open to feedback, clear about goals; (3) FINANCIAL SUSTAINABILITY: diversification of research portfolio, identification of matching funding sources, departmental resource awards (eg, T-/P-grants), leveraging of institutional resources, negotiation of formalized/formulaic funds flow investment from academic medical center toward science, philanthropy; (4) STRUCTURAL/STRATEGIC SUPPORT: Structural: grants administrative support, biostats/bioinformatics support, clinical trial and research support, regulatory support, shared departmental laboratory space/equipment; Strategic: hiring diverse surgeon-scientist/scientists faculty across DOS, strategic faculty retention/ recruitment, philanthropy, career development support, progress tracking, grant writing support, DOS-wide research meetings, regular DOS strategic research planning; (5) COMMUNITY AND CULTURE: Community: right mix of faculty, connection surgeon with broad scientific community; Culture: building research infrastructure, financial support for research, projecting importance of research (awards, grand rounds, shoutouts); (6) THE ROLE OF INSTITUTIONS: Foundation: research space co-location, flexible start-up packages, courses/mock study section, awards, diverse institutional mentorship teams; Nurture: institutional infrastructure, funding (eg, endowed chairs), promotion friendly toward surgeon-scientists, surgeon-scientists in institutional leadership positions; Expectations: RVU target relief, salary gap funding, competitive starting salaries, longitudinal salary strategy; (7) THE ROLE OF FUNDING AGENCIES: change surgeon research training paradigm, offer alternate awards to K-awards, increasing salary cap to reflect market reality, time extension for surgeon early-stage investigator status, surgeon representation on study section, focused award strategies for professional societies/foundations. CONCLUSIONS: Authentic recommitment from surgeon leaders with intentional and ambitious actions from institutions, corporations, funders, and society is essential in order to reap the essential benefits of surgeon-scientists toward advancements of science.

RESUMO

BACKGROUND: Radioactive tracer injections for breast cancer sentinel lymph node mapping can be painful. In this randomized trial, we compared four approaches to topical pain control for radiotracer injections. METHODS: Breast cancer patients were randomized (9 April 2021-8 May 2022) to receive the institutional standard of ice prior to injection (n = 44), or one of three treatments: ice plus a vibrating distraction device (Buzzy®; n = 39), 4% lidocaine patch (n = 44), or 4% lidocaine patch plus ice plus Buzzy® (n = 40). Patients completed the Wong-Baker FACES® pain score (primary outcome) and a satisfaction with pain control received scale (secondary). Nuclear medicine technologists (n = 8) rated perceived pain control and ease of administration for each patient. At study conclusion, technologists rank-ordered treatments. Data were analyzed as intention-to-treat. Wilcoxon rank-sum tests were used to compare pain scores of control versus pooled treatment arms (primary) and then control to each treatment arm individually (secondary). RESULTS: There were no differences in pain scores between the control and treatment groups, both pooled and individually. Eighty-five percent of patients were 'satisfied/very satisfied' with treatment received, with no differences between groups. No differences in providers' perceptions of pain were observed, although providers perceived treatments involving Buzzy© more difficult to administer (p < 0.001). Providers rated lidocaine patch as the easiest, with ice being second. CONCLUSION: In this randomized trial, no differences in patient-reported pain or satisfaction with treatment was observed between ice and other topical treatments. Providers found treatments using Buzzy® more difficult to administer. Given patient satisfaction and ease of administration, ice is a reasonable standard.

RESUMO

BACKGROUND: The 8th edition American Joint Committee on Cancer staging system combined anatomic stage (AS) with receptor status and grade to create prognostic stage (PS). PS has been validated in single-institution and cancer registry studies; however, missing human epidermal growth factor receptor 2 (HER2) status and variable treatment and follow-up create limitations. OBJECTIVE: Our objective was to compare the relative prognostic ability of PS versus AS to predict survival using breast cancer clinical trial data. METHODS: Women with non-metastatic breast cancer enrolled in six Alliance for Clinical Trials in Oncology trials were included (enrollment years 1997-2010). AS and PS were constructed using pathological tumor size, nodal status, estrogen receptor (ER), progesterone receptor (PR), HER2 status, and grade. Unadjusted Cox proportional hazard models were estimated to predict overall survival within 5 years, with AS and PS as predictor variables. The relative predictive power of staging models was assessed by comparing Harrell concordance indices (C-indices). Kaplan-Meier-based mortality estimates were compared by stage. RESULTS: Overall, 6924 women were included (median age 53 years); 45.2% were diagnosed with ER+/PR+/HER2- tumors, 26.2% with HER2+ tumors, and 17.1% with ER-/PR-/HER2- tumors. Median follow-up time was 5 years (interquartile range 2.95-5.00). PS significantly improved predictive performance (C-index 0.721) for overall survival compared with AS (0.700) (p = 0.020). Kaplan-Meier hazard estimates suggested PS did not distinguish mortality risk between patients with IIB and IIIA or IB and IIA disease. CONCLUSIONS: PS has significantly improved predictive performance for OS compared with AS. As systemic therapies evolve, it will be important to re-evaluate the prognostic staging system, particularly for patients with intermediate-stage cancers.

RESUMO

INTRODUCTION: The Commission on Cancer/National Quality Forum breast radiotherapy quality measure establishes that for women < 70 years, adjuvant radiotherapy after breast conserving surgery (BCS) should be started < 1 year from diagnosis. This was intended to prevent accidental radiotherapy omission or delay due to a long interval between surgery and chemotherapy completion, when radiation is delivered. However, the impact on patients not receiving chemotherapy, who proceed from surgery directly to radiotherapy, remains unknown. PATIENTS AND METHODS: Patients aged 18-69, diagnosed with stage I-III breast cancer as their first and only cancer diagnosis (2004-2016), having BCS, for whom this measure would be applicable, were reviewed from the National Cancer Database. RESULTS: Among 308,521 patients, the median age was 57.0 years, and > 99% of all patients were compliant with the measure. The cohort of interest included 186,650 (60.5%) patients not receiving chemotherapy, with a mean age of 57.9 years. Of these, 90.5% received external beam radiotherapy (EBRT) and 9.5% brachytherapy. Among them, 24.9% started radiotherapy > 8 weeks after surgery. In a multivariable model, delay from surgery to radiotherapy increased the hazard ratios for overall survival to 9.0% (EBRT) per month and 3.0% (brachytherapy) per week. CONCLUSION: While 99.9% of patients undergoing BCS without chemotherapy remain compliant with the current quality measure, 25% have delays > 8 weeks to start radiation, which is associated with impaired survival. These data suggest that the current quality measure should be dichotomized into two, with or without chemotherapy, in order to impel prompt radiotherapy initiation and maximize outcomes in all patients.

RESUMO

PURPOSE: Controversy remains regarding the optimal margin width for patients with ductal carcinoma in situ (DCIS) who undergo breast conserving surgery (BCS). METHODS: Women with a primary DCIS diagnosis were enrolled in a statewide population-based cohort from 1997 to 2006. Patients were surveyed every two years with follow-up data available through 2016. Surgical pathology reports were collected for 559 participants following breast conserving surgery. Multivariable Cox proportional hazard models evaluated relationships between locoregional recurrence (LRR) and margin width in the presence or absence of adjuvant radiation therapy while controlling for age, menopausal status and duration of endocrine therapy use. RESULTS: The majority of women in this study were over 50yo (74%), 34% had high grade disease, and 77% underwent radiation. The overall LRR rate was 12%. A LRR occurred in 46 women who had radiation (11%) and 23 women who did not undergo radiation (19%). Univariate analysis identified smaller margin width, younger age, premenopausal status, no radiotherapy, and shorter endocrine therapy use associated with LRR. Multivariable models demonstrated that close margins (< 2 mm) were associated with an increased risk of recurrence when compared to margins ≥ 2 mm in width whether women received radiation (HR 1.98 CI 0.87-4.54) or not (HR 1.32 CI 0.27-6.49), but confidence intervals were wide. CONCLUSIONS: In this study, patients with DCIS and close margins were less likely to experience recurrence after routine re-excision to margins greater than 2 mm.

RESUMO

PURPOSE: To examine how treatment delays brought on by the COVID-19 pandemic impacted the physical and emotional well-being of physicians treating these patients. METHODS: A cross-sectional survey of physician breast specialists was posted from April 23rd to June 11th, 2020 on membership list serves and social media platforms of the National Accreditation Program for Breast Centers and the American Society of Breast Surgeons. Physician well-being was measured using 6 COVID-19 burnout emotions and the 4-item PROMIS short form for anxiety and sleep disturbance. We examined associations between treatment delays and physician well-being, adjusting for demographic factors, COVID-19 testing and ten COVID-19 pandemic concerns. RESULTS: 870 physicians completed the survey, 61% were surgeons. The mean age of physicians was 52 and 548 (63.9%) were female. 669 (79.4%) reported some delay in patient care as a result of the COVID-19 pandemic. 384 (44.1%) and 529 (60.8%) of physicians scored outside normal limits for anxiety and sleep disturbance, respectively. After adjusting for demographic factors and COVID-19 testing, mean anxiety and COVID-19 burnout scores were significantly higher among physicians whose patients experienced either delays in surgery, adjuvant chemotherapy, radiation, breast imaging or specialty consultation. A multivariable model adjusting for ten physician COVID-19 concerns and delays showed that "delays will impact my emotional well-being" was the strongest concern associated with anxiety, sleep disturbance and COVID-19 burnout factors. CONCLUSIONS: Breast cancer treatment delays during the initial surge of the COVID-19 pandemic in the United States were associated with a negative impact on physician emotional wellness.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has resulted in rapid and regionally different approaches to breast cancer care. METHODS: In order to evaluate these changes, a COVID-19-specific registry was developed within the American Society of Breast Surgeons (ASBrS) Mastery that tracked whether decisions were usual or modified for COVID-19. Data on patient care entered into the COVID-19-specific registry and the ASBrS Mastery registry from 1 March 2020 to 15 March 2021 were reviewed. RESULTS: Overall, 177 surgeons entered demographic and treatment data on 2791 patients. Mean patient age was 62.7 years and 9.0% (252) were of African American race. Initial consultation occurred via telehealth in 6.2% (173) of patients and 1.4% (40) developed COVID-19. Mean invasive tumor size was 2.1 cm and 17.8% (411) were node-positive. In estrogen receptor-positive/human epidermal growth factor receptor 2-negative (ER+/HER2-) disease, neoadjuvant endocrine therapy (NET) was used as the usual approach in 6.9% (119) of patients and due to COVID-19 in an additional 31% (542) of patients. Patients were more likely to receive NET due to COVID-19 with increasing age and if they lived in the Northeast or Southeast (odds ratio [OR] 1.1, 2.3, and 1.7, respectively; p < 0.05). Genomic testing was performed on 51.5% (781) of estrogen-positive patients, of whom 20.7% (162) had testing on the core due to COVID-19. Patients were less likely to have core biopsy genomic testing due to COVID-19 if they were older (OR 0.89; p = 0.01) and more likely if they were node-positive (OR 4.0; p < 0.05). A change in surgical approach due to COVID-19 was reported for 5.4% (151) of patients. CONCLUSION: The ASBrS COVID-19 registry provided a platform for monitoring treatment changes due to the pandemic, highlighting the increased use of NET.

RESUMO

PURPOSE: Randomized controlled trials demonstrate that omission of radiation therapy (RT) in older women with early-stage cancer undergoing breast conserving surgery (BCS) is an "acceptable choice." Despite this, high RT rates have been reported. The objective was to evaluate the impact of patient- and system-level factors on RT rates in a contemporary cohort. METHODS: Through the National Cancer Data Base, we identified women with clinical stage I estrogen receptor-positive breast cancer who underwent BCS (n = 84,214). Multivariable logistic regression identified patient, tumor, and system-level factors associated with RT. Joinpoint regression analysis calculated trends in RT use over time stratified by age and facility-type, reporting annual percent change (APC). RESULTS: RT rates decreased from 2004 (77.2%) to 2015 (64.3%). The decline occurred earliest and was most pronounced in older women treated at academic facilities. At academic facilities, the APC was - 5.6 (95% CI - 8.6, - 2.4) after 2009 for women aged > 85 years, - 6.4 (95% CI - 9.0, - 3.8) after 2010 for women aged 80 - < 85 years, - 3.7 (95% CI - 5.6, - 1.9) after 2009 for women aged 75 - < 80, and - 2.4 (95% CI, - 3.1, - 1.6) after 2009 for women aged 70 - < 75. In contrast, at community facilities rates of RT declined later (2011, 2012, and 2013 for age groups 70-74, 75-79, and 80-84 years). CONCLUSIONS: RT rates for older women with early-stage breast cancer are declining with patient-level variation based on factors related to life expectancy and locoregional recurrence. Facility-level variation suggests opportunities to improve care delivery by focusing on barriers to de-implementation of routine use of RT.

RESUMO

BACKGROUND: Breast-conserving surgery (BCS) and mastectomy have equivalent survival for ductal carcinoma in situ (DCIS), allowing patients to participate in selecting a personalized surgical option; however, this decision-making role can increase patient anxiety. Data evaluating patient satisfaction with their decision to undergo BCS versus mastectomy for the treatment of DCIS are limited. METHODS: Women with DCIS were enrolled in a population-based, state-wide cohort from 1997 to 2006. Participants were surveyed about their satisfaction with their surgical and reconstruction decisions. Quality-of-life (QoL) evaluations were performed with biennial follow-up surveys though 2016. Multivariable logistic regression modeling examined the relationship between type of surgery and reconstruction with patient satisfaction. RESULTS: Overall, 1537 women were surveyed, on average, 2.9 years following DCIS diagnosis. Over 90% reported satisfaction with their treatment decision regardless of surgery type. Women who underwent mastectomy with reconstruction were more likely to report lower levels of satisfaction than women who underwent BCS (odds ratio [OR] 2.98, 95% confidence interval [CI] 1.18-7.51, p < 0.01). However, over 80% of women who underwent mastectomies reported satisfaction with their reconstruction decision. Women without reconstruction had the highest levels of satisfaction, while women with implants were more likely to be dissatisfied (implant + autologous: OR 2.77, 95% CI 1.24-6.24; implant alone: OR 4.02, 95% CI 1.947-8.34, p ≤ 0.01). QoL scores were not associated with differences in surgical or reconstruction satisfaction at 5, 10, and 15 years following DCIS diagnosis. CONCLUSIONS: Women undergoing surgery for DCIS express satisfaction with their treatment decisions. Following mastectomy, most women are satisfied with their reconstruction decision, including women who did not undergo reconstruction.

RESUMO

Delays in the initiation of adjuvant chemotherapy or radiation therapy are associated with worse outcomes in patients undergoing treatment for breast cancer. However, the impact of the time to initiation of neo-adjuvant chemotherapy (NAC) on patient outcomes has not previously been studied. The purpose of this study was to determine whether delays in NAC initiation impact patient survival. The National Cancer Database was queried for women ≥ 18 years old who underwent NAC within 6 months of being diagnosed with stage I-III invasive breast cancer in 2010-2011. ER+ or PR+, Her2- cancers were excluded from analysis. Multivariable Cox proportional hazard modeling was used to evaluate the relationship between time to NAC, sociodemographic, diagnosis, and treatment factors with patient survival. The median age of the 12 806 women included in this study was 52 (range 21-90) with 62% presenting with cT2 disease and 62% with nodal involvement. Half of the women (50%) had triple negative, 30% ER/PR+Her2+ and 20% ER-PR-Her2+ cancers. The median time to starting NAC was 4 weeks (range 0-26) for all subtypes. Time to NAC initiation was not associated with a difference in survival for triple negative or Her2+ cancers. Delays from diagnosis to starting NAC are not associated with worse survival for patients with Her2+ or triple negative breast cancer. This study demonstrates that the majority of women in the modern era start NAC in a timely fashion and delays in starting NAC within 6 months of diagnosis do not impact long-term patient outcomes.

RESUMO

Percutaneous microwave ablation (MWA) is a promising technology for patients with breast cancer, as it may help treat individuals who have less aggressive cancers or do not respond to targeted therapies in the neoadjuvant or pre-surgical setting. In this study, we investigate changes to the microwave dielectric properties of breast tissue that are induced by MWA. While similar changes have been characterized for relatively homogeneous tissues, such as liver, those prior results are not directly translatable to breast tissue because of the extreme tissue heterogeneity present in the breast. This study was motivated, in part by the expectation that the changes in the dielectric properties of the microwave antenna's operation environment will be impacted by tissue composition of the ablation target, which includes not only the tumor, but also its margins. Accordingly, this target comprises a heterogeneous mix of malignant, healthy glandular, and adipose tissue. Therefore, knowledge of MWA impact on breast dielectric properties is essential for the successful development of MWA systems for breast cancer. We performed ablations in 14 human ex-vivo prophylactic mastectomy specimens from surgeries that were conducted at the UW Hospital and monitored the temperature in the vicinity of the MWA antenna during ablation. After ablation we measured the dielectric properties of the tissue and analyzed the tissue samples to determine both the tissue composition and the extent of damage due to the ablation. We observed that MWA induced cell damage across all tissue compositions, and found that the microwave frequency-dependent relative permittivity and conductivity of damaged tissue are lower than those of healthy tissue, especially for tissue with high fibroglandular content. The results provide information for future developments on breast MWA systems.

RESUMO

Patients who carry the BRCA1 and BRCA2 gene mutations have an underlying genetic predisposition for breast and ovarian cancers. These deleterious genetic mutations are the most common genes implicated in hereditary breast and ovarian cancers. This monograph summarizes the evidence behind current screening recommendations, reviews imaging protocols specific to this patient population, and illustrates some of the imaging nuances of breast and ovarian cancers in this clinical setting.

RESUMO

Background Risk-based screening in women 40-49 years old has not been evaluated in routine screening mammography practice. Purpose To use a cross-sectional study design to compare the trade-offs of risk-based and age-based screening for women 45 years of age or older to determine short-term outcomes. Materials and Methods A retrospective cross-sectional study was performed by using a database of 20 539 prospectively interpreted consecutive digital screening mammograms in 10 280 average-risk women aged 40-49 years who were screened at an academic medical center between January 1, 2006, and December 31, 2013. Two hypothetical screening scenarios were compared: an age-based (≥45 years) scenario versus a risk-based (a 5-year risk of breast cancer greater than that of an average 50-year-old) scenario. Risk factors for risk-based screening included family history, race, age, prior breast biopsy, and breast density. Outcomes included breast cancers detected at mammography, false-positive mammograms, and benign biopsy findings. Short-term outcomes were compared by using the χ2 test. Results The screening population included 71 148 screening mammograms in 24 928 women with a mean age of 55.5 years ± 8.9 (standard deviation) (age range, 40-74 years). In women 40-49 years old, usual care included 50 screening-detected cancers, 1787 false-positive mammograms, and 384 benign biopsy results. The age-based (≥45 years) screening strategy revealed more cancers than did the risk-based strategy (34 [68%] vs 13 [26%] of 50; P < .001), while prompting more false-positive mammograms (899 [50.3%] vs 216 [12.1%] of 1787; P < .001) and benign biopsy results (175 [45.6%] vs 49 [12.8%] of 384; P < .001). The risk-based strategy demonstrated low levels of eligibility (few screenings) in the 40-44-year age group. Differences in outcomes in the 45-49-year age group explained the overall hypothetical screening strategy differences. Conclusion Risk-based screening for women 40-49 years old includes few women in the 40-44-year age range. Significant trade-offs in the 45-49-year age group explain the overall difference between hypothetical screening scenarios, both of which reduce the benefits as well as the harms of mammography for women 40-49 years old. © RSNA, 2019 Online supplemental material is available for this article.

RESUMO

Inflammation, and the organization of collagen in the breast tumor microenvironment, is an important mediator of breast tumor progression. However, a direct link between markers of inflammation, collagen organization, and patient outcome has yet to be established. A tumor microarray of 371 invasive breast carcinoma biopsy specimens was analyzed for expression of inflammatory markers, including cyclooxygenase 2 (COX-2), macrophages, and several collagen features in the tumor nest (TN) or the tumor-associated stroma (TS). The tumor microarray cohort included females, aged 18 to 80 years, with a median follow-up of 8.4 years. High expression of COX-2 (TN), CD68 (TS), and CD163 (TN and TS) predicted worse patient overall survival (OS). This notion was strengthened by the finding from the multivariate analysis that high numbers of CD163+ macrophages in the TS is an independent prognostic factor. Overall collagen deposition was associated with high stromal expression of COX-2 and CD163; however, total collagen deposition was not a predictor for OS. Conversely, local collagen density, alignment and perpendicular alignment to the tumor boundary (tumor-associated collagen signature-3) were predictors of OS. These results suggest that in invasive carcinoma, the localization of inflammatory cells and aligned collagen orientation predict poor patient survival. Additional clinical studies may help validate whether therapy with selective COX-2 inhibitors alters expression of CD68 and CD163 inflammatory markers.

RESUMO

BACKGROUND: Reduction mammaplasty is a common operation performed for healthy women. The estimated incidence of breast cancer diagnosed at the time of reduction mammaplasty varies from 0.06 to 4.5%, and information on the care of these patients is limited. This study aimed to determine the incidence of breast cancer identified incidentally during reduction mammaplasty and to characterize preoperative imaging. METHODS: Women 18 years of age or older who underwent reduction mammaplasty from 2013 to 2015 were identified from the Truven Health MarketScan® Research Databases. Patients with prior breast cancer were excluded. Descriptive statistics were calculated for patient characteristics, incidental breast cancer, preoperative breast imaging, and postoperative treatment. RESULTS: Reduction mammaplasty was performed for 18,969 women with a mean age of 42.5 years. Of these patients, 186 (0.98%) were incidentally found to have breast cancer, with 134 (0.71%) having invasive breast cancer and 52 (0.27%) having carcinoma in situ. The patients with incidentally found cancer were older than the patients without cancer (50.8 vs. 42.5 years; p < 0.001). Overall, 58.2% of the patients had undergone mammography before reduction mammoplasty. The rates were higher (> 80%) for the patients older than 40 years. Preoperative mammography was performed for 76.3% of those with a diagnosis of breast cancer at time of reduction mammoplasty. CONCLUSIONS: Breast cancer diagnosed incidentally at the time of reduction mammaplasty is uncommon and often radiographically occult. The majority of women older than 50 years appropriately received preoperative mammography. These data can be used to manage patient expectations about the potential for the incidental diagnosis of breast cancer at reduction mammaplasty, even with a negative preoperative mammography.

RESUMO

BACKGROUND: Patient participation in treatment decision-making is a health care priority. This study hypothesized that providing a decision aid before surgical consultation would better prepare patients for decision-making. The objective was to examine the impact of a decision aid versus high-quality websites on patients' perceptions of information conveyed during surgical consultation and satisfaction with the decision process. METHODS: Patients with stages 0 to 3 breast cancer were randomized. Surveys assessed perceptions of information conveyed, being asked surgical preference, and satisfaction with the decision process. Multivariable logistic regression assessed associations between outcomes and randomization arm, patient factors, and surgeon. Change in Pseudo-R2 assessed the comparative effect of these factors on perceptions of the information conveyed. RESULTS: The median patient age was 59 years. Most of the patients (98%) were white, and 62% were college educated (n = 201). The findings showed no association between randomization arm and perceptions of information conveyed, being asked surgical preference, or satisfaction with the decision process. Most of the patients reported discussing both breast-conserving therapy and mastectomy (69%) and being asked their surgical preference (65%). The surgeon seen was more important than the randomization arm or the patient factors in predicting patients' perceptions of information conveyed (explained 64-69% of the variation), and 63% of the patients were satisfied with the decision process. CONCLUSION: Use of a decision aid compared with high-quality websites did not increase patients' perceptions of information conveyed or satisfaction with the decision process. Although the surgeon seen influenced aspects of the patient experience, the surgeon was not associated with satisfaction. Understanding the factors driving low satisfaction is critical because this is increasingly used as a marker of health care quality.

RESUMO

BACKGROUND: Health literacy is the ability to perform basic reading and numerical tasks to function in the healthcare environment. The purpose of this study is to describe how health literacy is related to perceived coordination of care reported by breast cancer patients. METHODS: Data were retrieved from the Patient-Centered Outcomes Research Institute-sponsored "Share Thoughts on Breast Cancer" Study including demographic factors, perceived care coordination and responsiveness of care, and self-reported health literacy obtained from a mailed survey completed by 62% of eligible breast cancer survivors (N = 1221). Multivariable analysis of variance was used to characterize the association between presence of a single healthcare professional that coordinated care ("care coordinator") and perceived care coordination, stratified by health literacy level. RESULTS: Health literacy was classified as low in 24% of patients, medium in 34%, and high in 42%. Women with high health literacy scores were more likely to report non-Hispanic white race/ethnicity, private insurance, higher education and income, and fewer comorbidities (all p < 0.001). The presence of a care coordinator was associated with 17.1% higher perceived care coordination scores among women with low health literacy when compared to those without a care coordinator, whereas a coordinator modestly improved perceived care coordination among breast cancer survivors with medium (6.9%) and high (6.2%) health literacy. CONCLUSION: The use of a single designated care coordinator may have a strong influence on care coordination in patients with lower levels of health literacy.

RESUMO

Patients undergoing the addition of a contralateral prophylactic mastectomy with unilateral breast cancer have an increased and potentially doubled post-operative complication rate. One documented detriment from post-operative complications is the potential delay in initiating adjuvant therapy. To determine if the addition of a gynecologic and/or plastic reconstructive procedure to breast surgery results in an increased risk of postoperative complications and re-admissions, we evaluated outcomes in patients undergoing single vs multi-site surgery in a large national surgical database. We utilized the National Surgery Quality Improvement Program (NSQIP) database to identify patients who underwent breast surgery between 2011 and 2015. We extracted patients who underwent prophylactic oophorectomy with or without hysterectomy as a comparison group. Chi square analysis was used to assess postoperative outcomes including complications, readmission, and reoperation. All statistics were performed in SPSS v. 24. During the study timeframe, 77 030 patients had a solitary or combined breast surgical procedure and a second cohort of 124 patients underwent gynecologic surgery. Breast cancer patients who did not have a simultaneous reconstruction or gynecologic procedure were older with more comorbidities. Patients undergoing coordinated procedures had a significantly longer length of stay, higher complication, readmission, and reoperation rates (P < 0.001 for all) as compared with patients who underwent single site surgery. Patients with surgery for breast cancer, either with a plastic or gynecologic procedure, have greater postoperative complications. Higher complication rates for those with coordinated operations may lead to delays in adjuvant therapy and discussions regarding the indications for simultaneous surgery are recommended.

RESUMO

Every cancer survivor and his/her primary care provider should receive an individualized survivorship care plan (SCP) following curative treatment. Little is known regarding point-of-care utilization at primary care visits. We assessed SCP utilization in the clinical context of primary care visits. Primary care physicians and advanced practice providers (APPs) who had seen survivors following provision of an SCP were identified. Eligible primary care physicians and APPs were sent an online survey, evaluating SCP utilization and influence on decision-making at the point-of-care, accompanied by copies of the survivor's SCP and the clinic note. Eighty-eight primary care physicians and APPs were surveyed November 2016, with 40 (45%) responding. Most respondents (60%) reported discussing cancer or related issues during the visit. Information needed included treatment (66%) and follow-up visits, and the cancer team was responsible for (58%) vs primary care (58%). Respondents acquired this information by asking the patient (79%), checking oncology notes (75%), the SCP (17%), or online resources (8%). Barriers to SCP use included being unaware of the SCP (73%), difficulty locating it (30%), and finding needed information faster via another mechanism (15%). Despite largely not using the SCP for the visit (90%), most respondents (61%) believed one would be quite or very helpful for future visits. Most primary care visits included discussion of cancer or cancer-related issues. SCPs may provide the information necessary to deliver optimal survivor care but efforts are needed to reduce barriers and design SCPs for primary care use.

RESUMO

Survivorship care plans (SCPs) have been recommended as tools to improve care coordination and outcomes for cancer survivors. SCPs are increasingly being provided to survivors and their primary care providers. However, most primary care providers remain unaware of SCPs, limiting their potential benefit. Best practices for educating primary care providers regarding SCP existence and content are needed. We developed an education program to inform primary care providers of the existence, content, and potential uses for SCPs. The education program consisted of a 15-min presentation highlighting SCP basics presented at mandatory primary care faculty meetings. An anonymous survey was electronically administered via email (n = 287 addresses) to evaluate experience with and basic knowledge of SCPs pre- and post-education. A total of 101 primary care advanced practice providers (APPs) and physicians (35% response rate) completed the baseline survey with only 23% reporting prior receipt of a SCP. Only 9% could identify the SCP location within the electronic health record (EHR). Following the education program, primary care physicians and APPs demonstrated a significant improvement in SCP knowledge, including improvement in their ability to locate one within the EHR (9 vs 59%, p < 0.0001). A brief educational program containing information about SCP existence, content, and location in the EHR increased primary care physician and APP knowledge in these areas, which are prerequisites for using SCP in clinical practice.
