Breast Cancer-Major changes in the American Joint Committee on Cancer eighth edition cancer staging manual.

Answer questions and earn CME/CNE The revision of the eighth edition of the primary tumor, lymph node, and metastasis (TNM) classification of the American Joint Commission of Cancer (AJCC) for breast cancer was determined by a multidisciplinary team of breast cancer experts. The panel recognized the need to incorporate biologic factors, such as tumor grade, proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression prognostic panels into the staging system. AJCC levels of evidence and guidelines for all tumor types were followed as much as possible. The panel felt that, to maintain worldwide value, the tumor staging system should remain based on TNM anatomic factors. However, the recognition of the prognostic influence of grade, hormone receptor expression, and HER2 amplification mandated their inclusion into the staging system. The value of commercially available, gene-based assays was acknowledged and prognostic input added. Tumor biomarkers and low Oncotype DX recurrence scores can alter prognosis and stage. These updates are expected to provide additional precision and flexibility to the staging system and were based on the extent of published information and analysis of large, as yet unpublished databases. The eighth edition of the AJCC TNM staging system, thus, provides a flexible platform for prognostic classification based on traditional anatomic factors, which can be modified and enhanced using patient biomarkers and multifactorial prognostic panel data. The eighth edition remains the worldwide basis for breast cancer staging and will incorporate future online updates to remain timely and relevant.

The Eighth Edition AJCC Cancer Staging Manual: Continuing to build a bridge from a population-based to a more "personalized" approach to cancer staging.

The American Joint Committee on Cancer (AJCC) staging manual has become the benchmark for classifying patients with cancer, defining prognosis, and determining the best treatment approaches. Many view the primary role of the tumor, lymph node, metastasis (TNM) system as that of a standardized classification system for evaluating cancer at a population level in terms of the extent of disease, both at initial presentation and after surgical treatment, and the overall impact of improvements in cancer treatment. The rapid evolution of knowledge in cancer biology and the discovery and validation of biologic factors that predict cancer outcome and response to treatment with better accuracy have led some cancer experts to question the utility of a TNM-based approach in clinical care at an individualized patient level. In the Eighth Edition of the AJCC Cancer Staging Manual, the goal of including relevant, nonanatomic (including molecular) factors has been foremost, although changes are made only when there is strong evidence for inclusion. The editorial board viewed this iteration as a proactive effort to continue to build the important bridge from a "population-based" to a more "personalized" approach to patient classification, one that forms the conceptual framework and foundation of cancer staging in the era of precision molecular oncology. The AJCC promulgates best staging practices through each new edition in an effort to provide cancer care providers with a powerful, knowledge-based resource for the battle against cancer. In this commentary, the authors highlight the overall organizational and structural changes as well as "what's new" in the Eighth Edition. It is hoped that this information will provide the reader with a better understanding of the rationale behind the aggregate proposed changes and the exciting developments in the upcoming edition.

The Medicare Appropriate Use Criteria Program: A Review of Recommendations for Testing in Coronary Artery Disease.

BACKGROUND: Congress established the Appropriate Use Criteria (AUC) Program to reduce unnecessary advanced imaging studies. Organizations that wish to develop AUC can apply to the Centers for Medicare & Medicaid Services (CMS) to qualify as provider-led entities (PLEs) under this program. Variable methods, content, and formatting of PLE-generated AUC could lead to clinician uncertainty about whether an advanced imaging test is appropriate or not. PURPOSE: To review AUC published by CMS-qualified PLEs focused on advanced imaging tests for coronary artery disease (CAD), a "priority clinical area" identified by CMS. DATA SOURCES: Publicly available data from the worldwide web searched on 29 August 2022. STUDY SELECTION: Approved AUC with recommendations related to testing for CAD. DATA EXTRACTION: Manual review of published AUC by all authors. DATA SYNTHESIS: Among the 17 CMS-qualified PLEs, only 7 had published AUC related to CAD. Substantial variation in the methods and formatting of these AUCs was observed. The number of clinical scenarios covered ranged from 6 to 210, and the number of advanced imaging methods covered ranged from 1 to 25. When specifically applied to clinical scenarios, many AUC offered no guidance on appropriateness; those that did conflicted with respect to appropriateness. LIMITATION: Other CMS-identified priority clinical areas were not evaluated. CONCLUSION: CMS-qualified AUC for imaging of CAD are heterogeneous and sometimes discrepant, creating substantial potential for uncertainty among clinicians seeking to provide their patients with appropriate imaging tests. PRIMARY FUNDING SOURCE: No funding was received for this study.

Systematic Review of Literature Citing the ISCHEMIA Trial.

PURPOSE OF REVIEW: Optimal therapy for patients with chronic coronary artery disease (CCD) has long been a topic under investigation and a subject of debate. Seeking to clarify appropriate management, the International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) trial compared medical management versus coronary angiography for patients with stable ischemic heart disease. Its reception in the medical community has been met with both acclaim and criticism. In light of such disparate views of this trial, a systematic review of the literature citing the ISCHEMIA trial was performed. RECENT FINDINGS: All articles citing the ISCHEMIA trial on PubMed as of July 21, 2023, were compiled and underwent qualitative analysis. A total of 430 articles were evaluated; 109 (25.3%) did not offer substantial commentary on ISCHEMIA and cite it as background evidence for further study. Of the commentary articles, the majority (224, 52.1%) gave balanced, honest appraisals of the ISCHEMIA trial. A total of 46 (10.7%) strongly praised the trial while another 39 (9.1%) were strongly critical of the results. Almost three-quarters of the literature citing the ISCHEMIA trial was commentary in nature, with roughly equal distribution across the spectrum of praise and criticism. Despite being one of the largest studies on CCD and coronary revascularization ever conducted, the impact of ISCHEMIA on the cardiology community appears to be mixed.

Physician Wellness in Academic Cardiovascular Medicine: A Scientific Statement From the American Heart Association.

Academic medicine as a practice model provides unique benefits to society. Clinical care remains an important part of the academic mission; however, equally important are the educational and research missions. More specifically, the sustainability of health care in the United States relies on an educated and expertly trained physician workforce directly provided by academic medicine models. Similarly, the research charge to deliver innovation and discovery to improve health care and to cure disease is key to academic missions. Therefore, to support and promote the growth and sustainability of academic medicine, attracting and engaging top talent from fellows in training and early career faculty is of vital importance. However, as the health care needs of the nation have risen, clinicians have experienced unprecedented demand, and individual wellness and burnout have been examined more closely. Here, we provide a close look at the unique drivers of burnout in academic cardiovascular medicine and propose system-level and personal interventions to support individual wellness in this model.

ACC/AHA/ASE/ASNC/ASPC/HFSA/HRS/SCAI/SCCT/SCMR/STS 2023 Multimodality Appropriate Use Criteria for the Detection and Risk Assessment of Chronic Coronary Disease.

The American College of Cardiology (ACC) Foundation, along with key specialty and subspecialty societies, conducted an appropriate use review of stress testing and anatomic diagnostic procedures for risk assessment and evaluation of known or suspected chronic coronary disease (CCD), formerly referred to as stable ischemic heart disease (SIHD). This document reflects an updating of the prior Appropriate Use Criteria (AUC) published for radionuclide imaging, stress echocardiography (echo), calcium scoring, coronary computed tomography angiography (CCTA), stress cardiac magnetic resonance (CMR), and invasive coronary angiography for SIHD. This is in keeping with the commitment to revise and refine the AUC on a frequent basis. As with the prior version of this document, rating of test modalities is provided side-by-side for a given clinical scenario. These ratings are explicitly not considered competitive rankings due to the limited availability of comparative evidence, patient variability, and the range of capabilities available in any given local setting1-4.This version of the AUC for CCD is a focused update of the prior version of the AUC for SIHD4. Key changes beyond the updated ratings based on new evidence include the following: 1. Clinical scenarios related to preoperative testing were removed and will be incorporated into another AUC document under development. 2. Some clinical scenarios and tables were removed in an effort to simplify the selection of clinical scenarios. Additionally, the flowchart of tables has been reorganized, and all clinical scenario tables can now be reached by answering a limited number of clinical questions about the patient, starting with the patient's symptom status. 3. Several clinical scenarios have been revised to incorporate changes in other documents such as pretest probability assessment, atherosclerotic cardiovascular disease (ASCVD) risk assessment, syncope, and others. ASCVD risk factors that are not accounted for in contemporary risk calculators have been added as modifiers to certain clinical scenarios. The 64 clinical scenarios rated in this document are limited to the detection and risk assessment of CCD and were drawn from common applications or anticipated uses, as well as from current clinical practice guidelines.5 These clinical scenarios do not specifically address patients having acute chest pain episodes. They may, however, be applicable in the inpatient setting if the patient is not having an acute coronary syndrome and warrants evaluation for CCD.Using standardized methodology, clinical scenarios were developed to describe common patient encounters in clinical practice focused on common applications and anticipated uses of testing for CCD. Where appropriate, the scenarios were developed on the basis of the most current ACC/American Heart Association guidelines. A separate, independent rating panel scored the clinical scenarios in this document on a scale of 1 to 9, following a modified Delphi process consistent with the recently updated AUC development methodology. Scores of 7 to 9 indicate that a modality is considered appropriate for the clinical scenario presented, midrange scores of 4 to 6 indicate that a modality may be appropriate for the clinical scenario, and scores of 1 to 3 indicate that a modality is rarely appropriate.

The Pivotal Leadership of Doctors R. Lee Clark and Murray M. Copeland in Transforming the Commission on Cancer (1955-1965).

In September 1959, Dr. Clark was appointed as Chair and Dr. Murray M Copeland as Vice Chair of the Committee on Cancer. With their typical leadership style to improve the functions and value of organizations, they reorganized and revitalized the Committee on Cancer during the next 6 years. Thus, Drs. Clark and Copeland and the Committee members developed more uniform standards of cancer registries, implemented the American Joint Committee on Cancer Staging and End Results Reporting (with Dr. Copeland as Chair), published a revised Manual for Cancer Programs (which defined minimum standards requisite for approval of a cancer service), established a new regionalization program (with liaison surgeons from each state), and planned all the cancer educational programs for the College's annual Clinical Congress and Sectional Meetings. Importantly, Clark and Copeland led a 10-year strategic plan (called the "Program of the Sixties") to expand and revitalize the scale and scope of the Committee's activities and to reorganize the Committee structure by including liaison members from other physician, oncologic, and hospital organizations. As Dr. Clark completed his 5-year tenure as Committee Chair in October 1964, he formally recommended a reorganization of the Committee on Cancer to assume an even greater role in the cancer community as the Commission on Cancer. As the new Committee Chair, Dr. Copeland shepherded this recommendation to the ACS Board of Regents, which was approved and implemented in July 1965. The Regents emphasized that the functions and activities of the Committee on Cancer had become so complex and far reaching (under Clark's and Copeland's leadership) that its many subcommittees had already assumed duties of committee stature. Dr. Copeland thus became the first Chair of the Commission on Cancer until October 1965, when Dr. John Cline became Chair. For his contributions to the cancer field and to the College of Surgeons, Dr. Clark received their Distinguished Service Award in October 1969 "for his life-long devotion to the treatment of patients and to research in cancer, for notable service to this College, particularly as Chairman of the Cancer Commission from 1960 to 1964."

Treatment Differences for Adrenocortical Carcinoma by Race and Insurance Status.

INTRODUCTION: To determine if treatment and clinical outcomes of adrenocortical carcinoma (ACC) vary by race and insurance status. METHODS: ACC patients from the National Cancer Database (2004-2017) were reviewed. Race was defined as White versus minority (Black and Hispanic). Insurance types were private (PI) versus other (Medicaid/uninsured/unknown). Metastatic ACC (M-ACC) was defined as distant metastases at the time of diagnosis; nonmetastatic ACC (NM-ACC) patient had no distant disease. RESULTS: Of 2351 NM-ACC patients, 83.6% were White and 16.4% minority. There were 1216 M-ACC patients, with 80.3% White and 19.8% minority. Both White NM-ACC and M-ACC patients had more PI (each P < 0.001). PI NM-ACC was associated with a shorter duration from diagnosis to first treatment (14 versus 18 d, P = 0.005). Both NM-ACC and M-ACC with PI were more likely to receive surgery (92.6% versus 86.9%, P = 0.001 and 35.4% versus 27%, P = 0.02) and to receive surgery sooner (13 versus 16 d, P = 0.03). M-ACC with PI were more likely to receive chemotherapy (63.6% versus 54.3%, P = 0.01) and to have lymph nodes examined (14.8% versus 8.6%, P = 0.02). Length of stay postoperatively was shorter for White NM-ACC (6 versus 7 d, P = 0.04) and M-ACC (8 versus 17 d, P = 0.02). For NM-ACC and M-ACC, the 30-d readmission, 90-d mortality, and overall survival were similar by race. A multivariable analysis showed minorities (OR 0.69, 95% confidence interval 0.54-0.88, P = 0.003) and patients without PI (OR 0.75, 95% confidence interval 0.58-0.97, P = 0.03) were less likely to have surgery. However, a multivariable analysis showed survival was similar for White versus minority patients and PI versus other. CONCLUSIONS: White NM-ACC or M-ACC and PI were more likely to receive surgery and timely multimodality care. These disparities were not associated with differences in 90-d mortality or overall survival.

The New Role of Telehealth in Contemporary Medicine.

PURPOSE OF REVIEW: Understand the current uses for telehealth as well as future directions as it relates to the COVID-19 pandemic and cardiovascular medicine. RECENT FINDINGS: Telehealth interventions in various forms have proven to be efficacious in the management of obesity, hypertension, glycemic control in diabetes, hyperlipidemia, medication adherence, and ICU length of stay and mortality. The use and study of such interventions have been greatly expanded during the pandemic partly due to the expanded coverage by payers. However, heterogenous interventions and a relative lack of cost analyses are barriers to more widespread adoption. Telehealth has proven efficacy for modifying risk factors for cardiovascular disease. To date, this has not been shown to translate to a reduction in hard cardiovascular endpoints such as mortality. With ongoing research and expanded funding, the role of telehealth is likely to evolve as the COVID pandemic continues.

Improving the Breast Surgeon's Ergonomic Workload for Nipple-Sparing Mastectomies Using Exercise and Operating Room Positioning Protocol.

BACKGROUND: The objective of this study was to examine whether an exercise program and standardized operating room positioning protocol (EOPP) would improve surgeon muscle workload and/or surgeon perception of mental/physical workload for nipple-sparing mastectomy (NSM). METHODS: This prospective study analyzed muscle workload by EMG of four surgeons performing NSM before and after an EOPP. Surveys were administered assessing surgeon perception of mental/physical workload. EMG data were analyzed using repeated-measures ANOVA, controlling for surgeon, first assistant, duration and difficulty of procedure, left or right side, and sequence of the procedure. RESULTS: A total of 56 NSM cases performed by 3 surgeons were analyzed. One surgeon was excluded because of muscle injury and undergoing active physical therapy during the study period. After implementation of the EOPP, the left (P = 0.005) and right (P = 0.020) upper trapezii muscles had a significant decrease in overall ergonomic workload but there was no significant change in overall ergonomic workload for the bilateral cervical erector spinae, anterior deltoid, and lumbar erector spinae muscle groups. When analyzing muscle group exertion by surgeon, there was significant variability in all muscles except the left cervical erector spinae. Following the EOPP, surgeons reported that the procedures were more physically (P = 0.01) and mentally (P = 0.002) demanding and visualization (P = 0.04) was worse. The breast laterality and sequence did not affect muscle exertion. CONCLUSIONS: An EOPP decreased the overall ergonomic workload of one muscle group for surgeons performing NSM but did not impact surgeon perception of mental/physical workload. Further investigation is needed to improve surgeon ergonomics.

Discrepancy between patient-reported and clinician-documented symptoms for myocardial perfusion imaging: initial findings from a prospective registry.

BACKGROUND: Occasionally, the symptoms reported by patients disagree with those documented in the medical record. We designed the Patient Centered Assessment of Symptoms (PCAS) registry to measure discrepancies between patient-reported and clinician-documented symptoms. OBJECTIVE: Use patient-derived symptoms data to measure discrepancies with clinical documentation. METHODS: The PCAS registry captured data from a prospective cohort of patients undergoing myocardial perfusion imaging (MPI) and includes free response and structured questions to gauge symptoms. Clinician-documented symptoms were extracted from the patients' medical records. The appropriateness of testing was determined twice: once using the patient-reported symptoms and once using the clinician-documented symptoms. RESULTS: A total of 90 subjects were enrolled, among whom diabetes (36.7%), prior coronary disease (28.9%), hypertension (80.0%) and hyperlipidemia (85.6%) were common. Percentage of patient-reported symptoms compared to clinician-documented symptoms and agreement were as follows: chest pain (patient 29.0%, clinician 36.6%, moderate [kappa = 0.54]), chest pressure (patient 18.3%, clinician 10.8%, fair [kappa = 0.27]), dyspnea (patient 41.0%, clinician 36.6%, fair [kappa = 0.28]), onset with exertion (patient 61.7%, clinician 59.6%, slight [kappa = 0.17]), symptoms same as prior coronary artery disease (patient 46.2%, clinician 15.3%, slight [kappa = 0.01]). As a result of these inconsistencies, appropriateness ratings were different for 13.3% (n = 12) subjects. CONCLUSION: In this prospective registry of patients undergoing MPI, we observed substantial disagreements between patient-reported and clinician-documented symptoms. Disagreement resulted in a considerable proportion of MPI appropriateness ratings also being incongruous.

Virtual Surgical Fellowship Recruitment During COVID-19 and Its Implications for Resident/Fellow Recruitment in the Future.

BACKGROUND: The COVID-19 pandemic has overlapped with the scheduled interview periods of over 20 surgical subspecialty fellowships, including the Complex General Surgical Oncology (CGSO) fellowships in the National Resident Matching Program and the Society of Surgical Oncology's Breast Surgical Oncology fellowships. We outline the successful implementation of and processes behind a virtual interview day for CGSO fellowship recruitment after the start of the pandemic. METHODS: The virtual CGSO fellowship interview process at the University of Chicago Medicine and NorthShore University Health System was outlined and implemented. Separate voluntary, anonymous online secure feedback surveys were email distributed to interview applicants and faculty interviewers after the interview day concluded. RESULTS: Sixteen of 20 interview applicants (80.0%) and 12 of 13 faculty interviewers (92.3%) completed their respective feedback surveys. Seventy-five percent (12/16) of applicants and all faculty respondents (12/12) stated the interview process was 'very seamless' or 'seamless'. Applicants and faculty highlighted decreased cost, time savings, and increased efficiency as some of the benefits to virtual interviewing. CONCLUSIONS: Current circumstances related to the COVID-19 pandemic require fellowship programs to adapt and conduct virtual interviews. Our report describes the successful implementation of a virtual interview process. This report describes the technical steps and pitfalls of organizing such an interview and provides insights into the experience of the interviewer and interviewee.

Trends in nonoperative management of papillary thyroid microcarcinoma.

BACKGROUND: In 2010, a Japanese trial of nonoperative management for papillary thyroid microcarcinomas (PTmC) was published. This study determines if the prevalence of nonoperative management in the United States has changed and if there are predictors of this approach. METHODS: Patients treated for PTmC between 2004 and 2015 in the National Cancer Data Base were identified. Inclusion criteria were: classic or follicular variant papillary cancer histology, tumor size 1 to 10 mm, cN0 disease and no extrathyroidal extension or metastatic disease. Nonoperative management was assessed over time and compared between 2004-2010 and 2010-2015. Logistic regression identified factors associated with nonoperative management. RESULTS: Of 65 381 PTmC patients, 344 (0.5%) were treated nonoperatively. The annual rate of nonoperative management was similar at 0.6% in 2004 to 0.4% in 2010 (P = .755) but increased to 0.9% in 2015 (P < .001). There was no difference in patient age, race, comorbidities, or reason for nonoperative management between the two periods. Academic centers managed more patients nonoperatively. Multivariable logistic regression suggests older age, facility type, location, Hispanic, Asian, and Native American ethnicity were associated with nonoperative management. CONCLUSION: The vast majority of PTmC in the United States is treated with an operation. A small but significant increase in nonoperative management occurred between 2004-2010 and 2010-2015.

Multimodality imaging: Bird's eye view from the 2019 American College of Cardiology Scientific Sessions.

The 2019 American College of Cardiology Scientific Sessions displayed innovation in many areas for the evaluation and management of cardiovascular disease from preventive evaluation and care to advanced interventions. Imaging played a central role in these developments with a highlight of the conference being the imaging research presented. This review will summarize key imaging studies which were presented at this scientific meeting which will lead to innovation in the evaluation and management of cardiovascular disease. Experts in nuclear imaging (DW/MA), echocardiography (MS), cardiac magnetic resonance (SL), and cardiac computed tomography (RB) selected abstracts which they found to be of particular interest to the multimodality imaging audience and were integrated into this review (LP).

Parathyroidectomy is Safe in Elderly Patients: A National Surgical Quality Improvement Program Study.

BACKGROUND: With increasing age, the incidence of hyperparathyroidism is increased. This study evaluates parathyroidectomy outcomes in elderly patients. METHODS: Primary hyperparathyroidism patients having parathyroidectomy as listed in the 2005-2017 ACS-NSQIP database were separated by age: ≤60, 61-79 and ≥80. Outcomes included complications, 30-day mortality, return to the OR, operating times, and hospital length of stay (LOS). Multivariable logistic regression was used to compare patients 61-79 and ≥80 to those ≤60. Patients ≤60 and ≥80 were propensity score matched using gender, race, BMI, smoking status, steroid use, modified frailty index (mFI), ASA class, procedure, setting, anesthesia, and wound class. Morbidity and mortality were compared to ACS-NSQIP database patients having elective inguinal hernia repair. RESULTS: Of 47,701 patients: 22,220 were ≤60, 22,683 were 61-79, and 2798 were ≥80. Patients ≥80 had more complications (2.3% vs. 1.5% for 61-79 and 1.0% for ≤60, p < 0.01), LOS > 1 day (10.3% vs. 5.8% and 6.7%, p < 0.01), and mortality (0.21% vs. 0.11% and 0.03%, p < 0.01). On multivariable analysis of the overall population, older age, male gender, steroid use, high mFI, outpatient procedure, and general anesthesia increased the risk of complications. On propensity score matched analysis, there was no difference in complications (1.5% vs. 2.2%, p = 0.06) or mortality (0.04% vs. 0.23%, p = 0.12) between patients ≤60 and ≥80. Parathyroidectomy morbidity and mortality was lower than that for elective inguinal hernia repair in patients ≥80 (2.3% vs. 10% and 0.21% vs. 1.1%, p < 0.01). CONCLUSIONS: Parathyroidectomy is a safe operation, offering lower morbidity and mortality than elective hernia repair in all age groups including octogenarians.

Survival with Follicular and Hurthle Cell Microcarcinoma Compared to Papillary Thyroid Microcarcinoma: A Population Study of 84,532 Patients.

BACKGROUND: This study compares survival in patients with the rare subtypes of follicular (FTmC) and Hurthle cell (HCmC) microcarcinoma compared to that of papillary thyroid (PTmC) microcarcinoma. METHODS: Patients with FTmC and HCmC were selected from the National Cancer Database 2004-2015 and compared with PTmC. Patient clinicopathological characteristics and overall survival (OS) were analyzed. Multivariable logistic and Cox regression analysis evaluated binary outcomes and predictors of survival. A propensity score matched analysis using age, gender, race, extrathyroidal extension (ETE), nodal status, distant metastasis, radiation, and operation was performed to evaluate the difference in OS with FTmC, HCmC, and PTmC. RESULTS: We identified 858 FTmC, 476 HCmC, and 82,056 PTmC. FTmC was less likely to have macroscopic ETE compared to PTmC (2.6% vs. 3.1% p = 0.03), but more likely to have distant metastasis (2.3% vs. 0.2%, p < 0.01). FTmC and HCmC were less likely to have nodal metastasis (2.7%, 2.5% vs. 10.9%, p < 0.01). Ten-year OS was decreased in patients with FTmC (91.4%, p = 0.04) and HCmC (89.8%, p < 0.01) compared to PTmC (93.5%). On multivariable analysis, histology was not associated with OS. With HCmC, older age (OR 1.13, p < 0.01) and male gender (OR 2.72, p = 0.03) were associated with decreased OS. In propensity matched analysis, there was no difference in 10-year OS with FTmC and PTmC (91.4% vs. 93.7%, p = 0.54), but HCmC had decreased OS compared to PTmC (89.8% vs. 94.3%, p = 0.04). CONCLUSIONS: Patients with FTmC have comparable OS to those with PTmC, but HCmC has decreased OS especially in older and male patients.

Treatment delays from transfers of care and their impact on breast cancer quality measures.

PURPOSE: Despite delays between diagnosis and surgery adversely affecting survival, patients frequently transfer their breast cancer care between institutions. This study was performed to assess the prevalence and effect of such transfers of care (TsOC) on the time to surgery, and its impact on current time-dependent breast cancer quality metrics at Commission on Cancer (CoC) and National Accreditation Program for Breast Centers (NAPBC)-accredited institutions. METHODS: Patients having non-metastatic invasive breast cancer diagnosed between 2006 and 2015 at CoC and NAPBC centers ("reporting facilities") in the National Cancer Database were reviewed. TsOC refer to transferring into or out of a reporting facility between diagnosis and surgery. RESULTS: Among 622,793 patients, 36.6% of patients transferred care. TsOC add 7.3, 7.8, 8.7, and 9.8 days in time to surgery, chemotherapy, radiotherapy, and endocrine therapy, respectively (p's < 0.0001). On multivariable analysis, the odds of surgery occurring > 90 days from diagnosis were greatest for patients undergoing unilateral or bilateral mastectomy, Black or Hispanic patients, and those having TsOC (ORs > 1.73, p's < 0.0001). TsOC increase the odds of non-compliance, per patient, for chemotherapy, radiotherapy and endocrine therapy time-dependent measures by 65.4%, 25.6%, and 56.5%, respectively (p < 0.0001). CONCLUSIONS: TsOC for newly diagnosed breast cancers to or from an accredited facility result in delays in time to surgery which can affect compliance with time-dependent quality measures. Facilities frequently receiving transferred patients may be most adversely affected. Although non-compliance with these quality measures is low, institutions and accrediting bodies should be aware of these associations in order to comply with time-dependent standards.

Are we Overtreating Hormone Receptor Positive Breast Cancer with Neoadjuvant Chemotherapy? Role of OncotypeDx® for Hormone Receptor Positive Patients Undergoing Neoadjuvant Chemotherapy.

BACKGROUND: The utilization of OncotypeDx in the setting of neoadjuvant chemotherapy (NCT) is not well defined. The objective of this study was to determine what proportion of hormone receptor (HR)-positive patients undergoing NCT would not benefit from chemotherapy based on OncotypeDx recurrence scores (RS) and predictors of a high RS as defined by the TAILORx trial. METHODS: The National Cancer Data Base was used to identify patients with unilateral clinical stage I-III HR+/Her2- breast cancer who had an OncotypeDx score and who had undergone NCT. Patients undergoing adjuvant chemotherapy were used as a comparison group. RESULTS: Of 307,666 patients, 41.8% had testing with OncotypeDx. Of these, 76.6% had no chemotherapy, 22.3% adjuvant chemotherapy, and 1.1% NCT. OncotypeDx testing in NCT patients increased from 4.9% in 2010 to 8.2% in 2015. Of NCT patients with OncotypeDx testing, 11.6% had RS < 11, 44.4% RS 11-25, and 43.9% RS > 25. In patients age ≤ 50 years, 14.5% had RS < 11, 12.4% RS 11-15, 31.4% RS 16-25, and 41.7% RS > 25. Predictors of RS > 25 on multivariable analysis included grade 3 tumors (odds ratio [OR] 3.83) and PR-negative tumors (OR 5.26) but not clinical T or N stage (p > 0.05). CONCLUSIONS: More than half of patients with OncotypeDx testing are being overtreated with NCT, and a third of younger patients are being overtreated. Predictors of a high RS are reliably available at core biopsy, suggesting an application of OncotypeDx in determining the need for NCT for some HR-positive breast cancers.

The "Nipple Whipple"?! A Pilot Study to Assess the Ergonomic Effects of Nipple-Sparing Mastectomy.

BACKGROUND: Nipple-sparing mastectomies (NSMs) with reconstruction are believed to be more difficult to perform than skin-sparing mastectomies (SSMs), but there is little quantitative data to support this claim. METHODS: This prospective study analyzed four surgeons performing mastectomies. Electromyography (EMG) electrodes placed on selected muscle groups on each surgeon were used to capture muscle exertion intraoperatively and a percentage of maximum voluntary exertion was calculated (%MVE). Data regarding surgeon demographics, exercise habits, musculoskeletal problems, and surgery-specific workload was collected using a questionnaire. RESULTS: A total of 61 mastectomies were analyzed; 40 were NSM and 21 were SSM/total mastectomies. NSM were considered to be more mentally demanding and physically demanding than SSM (p < 0.001). When the surgeons' EMG data was analyzed as a group, there was a statistically significant difference in %MVE for NSM versus SSM at high muscle activity in bilateral anterior deltoid muscle groups and at average muscle activity for the left anterior deltoid muscle only. At low muscle activity, there was a statistically significant increase in activation for SSM versus NSM in bilateral cervical erector spinae. Repeated measures ANOVA was performed, which showed statistically significant differences at high muscle activity between NSM and SSM in the left cervical erector spinae and bilateral anterior deltoid muscles. CONCLUSIONS: Our pilot study shows that intraoperative EMGs can assess muscle activity for mastectomy operations and show a difference between NSM and SSM. This is the first study to provide quantitative data on muscle strain with NSM.

Compliance with Cancer Quality Measures Over Time and Their Association with Survival Outcomes: The Commission on Cancer's Experience with the Quality Measure Requiring at Least 12 Regional Lymph Nodes to be Removed and Analyzed with Colon Cancer Resections.

BACKGROUND: Many quality measures in cancer care are process measures. The rates of compliance for these measures over time have not been well described, and the relationships between measure compliance and survival are not well understood. METHODS: The National Cancer Database, representing cancer registry data from approximately 1500 Commission on Cancer (CoC) cancer programs, was queried to determine the rates of compliance, with the CoC's colon cancer quality measure requiring 12 regional lymph nodes be removed at resection. Data were assessed in 2003, before the measure was reported to programs, through 2015. Measure compliance and risk-adjusted survival were examined by hospital type. RESULTS: From 2003 to 2015, 544,018 cases of colon cancer were analyzed for number of nodes removed. In 2003, compliance was 52.8% and National Cancer Institute (NCI) centers had the highest compliance rate (69.0%), followed by academic cancer centers (61.9%), comprehensive community hospitals (50.9%), and community hospitals (44.0%). Between 2003 and 2015, compliance improved for all hospital types, although differences remained. Risk-adjusted survival in 2009 was better at NCI centers [hazard ratio (HR) 0.76] than at academic cancer centers (HR 0.90), which had better survivals than comprehensive community programs (HR 0.93) when compared with patients treated at community hospitals. CONCLUSION: After introduction of this quality measure, performance at CoC-accredited hospitals improved over the subsequent 13 years, and survival by hospital type paralleled measure compliance by hospital type. This demonstrated measurement may be associated with improvements in performance, and that there are differences in performance and outcome by hospital type.
