RESUMEN
OBJECTIVE: In this cross-sectional study of 237 older adults, we ascertained the importance of seven pain treatment goals and identified factors associated with their perceived importance. METHODS: Participants (mean age = 72 years) ranked each goal (e.g., pain reduction; finding a cure) on a 1 (not at all important) to 10 (extremely important) scale. We used general linear models to identify sociodemographic and pain factors independently associated with the perceived importance of each goal and repeated measures mixed models to examine their relative importance. RESULTS: The goal with the lowest adjusted score was "minimize harmful side effects from pain medications" with a mean (standard error [SE]) of 6.75 (0.239), while the highest ranked goals, "finding a cure," and "reducing my pain" had mean scores of 8.06 (0.237) and 7.89 (0.235), respectively. Pain reduction did not differ significantly from the average of the other 6 goals (P = .072) but was significantly different when compared with the goals of minimizing side effects (P < .0001) and finding a cause for the pain (P = .047), and different from the average of the five other goals excluding finding a cure (P = .021). We did not identify differences in the importance of the seven goals by gender or race/ethnicity. Age was inversely associated with the goals of minimizing harmful side effects and decreasing pain's effects on everyday activities. Pain reduction was rated more important than all other goals but finding a cure. CONCLUSIONS: Future research is needed to establish the benefits of eliciting treatment goals when delivering pain care to older adults.

Despite the fact that Asians constituted a sizeable proportion of those exposed to the World Trade Center attack on September 11, 2001 due to its proximity to Chinatown and many South Asians working in the nearby buildings, no study had focused on examining the mental health impact of the attack in this group. Based on data collected by the World Trade Center Health Registry from a sample of 4721 Asians 2-3 years after the disaster, this study provides a baseline investigation for the prevalence and the risk and protective factors for PTSD among Asian Americans directly exposed to the attack and compared this population against 42,862 non-Hispanic Whites. We found that Asians had a higher prevalence of PTSD compared to Whites (14.6 vs 11.7%). "Race-specific factors" significantly associated to PTSD in the multivariate analyses were noted among sociodemographics: higher education was protective for Whites but a risk factor for Asians; being employed was protective for Whites but had no effect for Asians; and being an immigrant was a risk factor for Whites but had no effect for Asians. However, income was a protective factor for both races. Other "universal factors" significantly increased the odds of PTSD symptoms but showed no racial differences, including exposure to the disaster and the presence of lower respiratory symptoms which intensified odds of PTSD by the greatest magnitude (3.6-3.9 times). Targeted effort to reach out to Asians is essential for prevention and follow up treatment given this group's striking history of underutilization of mental health services.

This study investigated patterns of probable posttraumatic stress disorder (PTSD) and their predictors among 2,431 Asian American and 31,455 non-Hispanic White World Trade Center (WTC) Registry participants 2-3 years and 5-6 years after the WTC attack. Participants were divided into four PTSD pattern groups: resilient, remitted, delayed onset, and chronic. Asians had a lower proportion in the resilient group (76.5% vs. 79.8%), a higher proportion in the chronic (8.6% vs. 7.4%) and remitted (5.9% vs. 3.4%) groups, and a similar proportion in the delayed onset group (about 9%) compared to Whites. In multinomial logistic regression analyses, disaster exposure, immigrant status, lower income, pre-attack depression/anxiety, and lower respiratory symptoms were associated with increased odds of chronic and delayed onset PTSD (vs. resilience) among both races. Education and employment were protective against chronic and delayed onset PTSD among Whites only. These results can inform targeted outreach efforts to enhance prevention and treatment for Asians affected by future events.

Penile cancer (PeCa) is a rare malignancy with potentially devastating effects. Squamous cell carcinoma is the most common variant with distinct precancerous lesions before development into invasive disease. Involvement of the inguinal lymph nodes is the most important prognostic factor in PeCa, and once disease is present outside the groin, prognosis is poor. Metastatic PeCa is challenging to treat and often requires multidisciplinary approaches in management. Due to its rarity, molecular understanding of the disease continues to be limited with most studies based on small, single center series. Thus far, it appears PeCa has diverse mechanisms of carcinogenesis affecting similar molecular pathways. In this review, we evaluate the current landscape of the molecular carcinogenesis of PeCa and explore ongoing research on potential actionable targets of therapy. The emergence of anti-epidermal growth factor receptor (EGFR) and other immunotherapeutic strategies may improve outcomes for PeCa patients.

Homelessness affects a large and increasing number of families in the United States, and exposure to violence and other potentially traumatic events is common among homeless families. It is important to understand more about this population and, more specifically, about the relationship between youth mental health and caregiver mental health and trauma exposure among homeless families, in order to better serve the needs of this vulnerable population. The objective of this study is to explore the relationships between caregiver exposure to violence, caregiver depression, and youth depression and behavioral problems among homeless families. Preliminary findings indicate that among this sample of homeless families, caregiver violence exposure has statistically significant relationships with both youth behavioral problems and youth depression symptoms, as mediated by caregiver depression. These findings indicate that youth behavioral health is associated with caregiver mental health, which, in turn, is associated with caregiver trauma exposure. This highlights the importance of taking into account adult mental health while treating youth externalizing and internalizing behaviors and ensuring that caregivers, too, have access to adequate treatment and supports. Furthermore, this treatment should be trauma informed, given the link between trauma and mental health.
RESUMEN
While normal B- and T-lymphocytes require antigenic ligands to become activated via their B- and T-cell receptors (BCR and TCR, respectively), B- and T-cell lymphomas show the broad spectrum of cell activation mechanisms regarding their dependence on BCR or TCR signaling, including loss of such dependence. These mechanisms are generally better understood and characterized for B-cell than for T-cell lymphomas. While some lymphomas, particularly the indolent, low-grade ones remain antigen-driven, other retain dependence on activation of their antigen receptors seemingly in an antigen-independent manner with activating mutations of the receptors playing a role. A large group of lymphomas, however, displays complete antigen receptor independence, which can develop gradually, in a stepwise manner or abruptly, through involvement of powerful oncogenes. Whereas some of the lymphomas undergo activating mutations of genes encoding proteins involved in signaling cascades downstream of the antigen-receptors, others employ activation mechanisms capable of substituting for these BCR- or TCR-dependent signaling pathways, including reliance on signaling pathways physiologically activated by cytokines. Finally, lymphomas can develop cell-lineage infidelity and in the extreme cases drastically rewire their cell activation mechanisms and engage receptors and signaling pathways physiologically active in hematopoietic stem cells or non-lymphoid cells. Such profound reprograming may involve partial cell dedifferentiation or transdifferentiation towards histocytes, dendritic, or mesodermal cells with various degree of cell maturation along these lineages. In this review, we elaborate on these diverse pathogenic mechanisms underlying cell plasticity and signaling reprogramming as well as discuss the related diagnostic and therapeutic implications and challenges.
RESUMEN
BACKGROUND AND OBJECTIVES: The COVID-19 pandemic severely disrupted hospice care, yet there is little research regarding how widespread disruptions affected clinician and family decision-making. We aimed to understand how the pandemic affected structures, processes, and outcomes of end-of-life care. RESEARCH DESIGN AND METHODS: Retrospective narrative chart review of electronic health records of 61 patients referred and admitted to hospice from three New York City geriatrics practices who died between March 1, 2020-March 31, 2021. We linked longitudinal, unstructured medical and hospice electronic health record notes to create a real-time, multi-perspective trajectory of patients' interactions with providers using directed content analysis. RESULTS: Most patients had dementia and were enrolled in hospice for 11 days. Care processes were shaped by structural factors (staffing, supplies, and governmental/institutional policies), and outcomes were prioritized by care teams and families (protecting safety, maintaining high-touch care, honoring patient values, and supporting patients emotionally and spiritually). Processes used to achieve these outcomes were decision-making, care delivery, supporting a "good death", and emotional and spiritual support. DISCUSSION AND IMPLICATIONS: Care processes were negotiated throughout end-of-life, with clinicians and families making in-the-moment decisions. Some adaptations were effective but also placed extraordinary pressure on paid and family caregivers. Health care teams' and families' goals to meet patients' end-of-life priorities can be supported by ongoing assessment of patient goals and process changes needed to support them, stronger structural supports for paid and family caregivers, incentivizing relationships across primary care and hospice teams, and extending social work and spiritual care.
RESUMEN
Home care workers played critical roles in meeting the complex medical and social needs of homebound adults during COVID-19, yet their contributions remain underappreciated. This study characterizes home care workers' roles during COVID-19 and examines how home care disruptions impacted homebound individuals and caregivers. Using a qualitative analysis of electronic medical records among a randomly sampled subset of homebound patients in a home-based primary care practice, we found that home care workers were essential in meeting existing and new needs of homebound individuals. Insufficient home care worker services, including unstable schedules and inadequate hours of paid care, became particularly disruptive, leading to risks for patients and their caregivers. Given their integral role on care teams, home care workers must be a policy focus to prepare for emergent situations and ensure that homebound individuals have access to high quality, stable home care.

Background: Research on deaths during COVID-19 has largely focused on hospitals and nursing homes. Less is known about medically complex patients receiving care in the community. We examined care disruptions and end-of-life experiences of homebound patients receiving home-based primary care (HBPC) in New York City during the initial 2020 COVID-19 surge. Methods: We conducted a retrospective chart review of patients enrolled in Mount Sinai Visiting Doctors who died between March 1-June 30, 2020. We collected patient sociodemographic and clinical data and analyzed care disruptions and end-of-life experiences using clinical notes, informed by thematic and narrative analysis. Results: Among 1300 homebound patients, 112 (9%) died during the study period. Patients who died were more likely to be older, non-Hispanic white, and have dementia than those who survived. Thirty percent of decedents had confirmed or probable COVID-19. Fifty-eight (52%) were referred to hospice and 50 enrolled. Seventy-three percent died at home. We identified multiple intersecting disruptions in family caregiving, paid caregiving, medical supplies and services, and hospice care, as well as hospital avoidance, complicating EOL experiences. The HBPC team responded by providing clinical, logistical and emotional support to patients and families. Conclusion: Despite substantial care disruptions, the majority of patients in our study died at home with support from their HBPC team as the practice worked to manage care disruptions. Our findings suggest HBPC's multi-disciplinary, team-based model may be uniquely suited to meet the needs of the most medically and socially vulnerable older adults at end of life during public health emergencies.

Background: Poorly controlled pain remains a problem for many patients with end-stage kidney disease requiring hemodialysis (ESKD/HD) and customary approaches to pain management (e.g., opioids, non-steroidals) confer substantial risk. Accordingly, non-pharmacologic therapies are needed for use in this population. Non-invasive transcranial Direct Current Simulation (tDCS) constitutes a promising nonpharmacologic method for pain management in affected individuals. Aims: This study seeks to: 1) determine the effects of an 8-week course of at-home tDCS vs. sham tDCS on pain intensity, pain interference, medication usage, quality of life, and mood; 2) determine if tDCS effects vary by race/ethnicity; and 3) ascertain patient satisfaction with device use. Methods: This double-blind, randomized, sham-controlled clinical trial will enroll 100 ESKD/HD patients with moderate-to-severe (≥4 on 0-10 scale) chronic pain. The active study intervention consists of 20â min of tDCS delivered over the primary motor cortex 5 days/week for 8 weeks. The comparator is a sham procedure that provides no effective stimulation. The primary outcome analysis will evaluate efficacy of tDCS for pain reduction after two months of stimulation. We will also assess the effects of treatment on analgesic consumption, pain interference, depressed mood, and quality of life. The statistical plan will include fixed classification factors for treatment (vs. sham), clinic sites, and assessment time, and the interaction of these factors adjusting for covariates (e.g., race/ethnicity, pain level). Conclusion: At-home tDCS constitutes a promising nonpharmacologic treatment for pain mitigation in persons with ESKD/HD. This unique RCT could transform the way pain is managed in this vulnerable population. Trial Registration: NCT05311956.
RESUMEN
Background: There is limited evidence regarding the challenges of providing hospice care to those dying at home during the COVID-19 pandemic. Objective: To describe the challenges of home hospice care and the specific types of disruptions in care processes experienced by patients and families. Design: Qualitative study of the electronic medical record notes of a large New York City (NYC) home-based primary care program. Setting/Subjects: Subjects were 58 patients referred to hospice who died during the initial NYC COVID-19 surge from March to June 2020. Results: We identified six domains of disruptions in home hospice care: delayed hospice enrollment, inability to conduct home visits, lack of needed supplies, communication failures, strained caregivers, and limitations of telehealth. Conclusions: This study provides a critical first analysis of disruptions in home hospice care that can feasibly be addressed and must be prioritized by hospices throughout the ongoing pandemic and in advance of future emergencies.

Background and Objectives: To examine the feasibility, acceptability, and preliminary efficacy of a positive affect skills intervention for middle-aged and older adults with fibromyalgia syndrome (FMS). Research Design and Methods: Ninety-five participants with FMS aged 50 and older (94% female) were randomized to 1 of 2 conditions: (a) Lessons in Affect Regulation to Keep Stress and Pain UndeR control (LARKSPUR; n = 49) or (b) emotion reporting/control (n = 46). LARKSPUR included 5 weeks of skill training that targeted 8 skills to help foster positive affect, including (a) noticing positive events, (b) savoring positive events, (c) identifying personal strengths, (d) behavioral activation to set and work toward attainable goals, (e) mindfulness, (f) positive reappraisal, (g) gratitude, and (h) acts of kindness. Outcome data were collected via online surveys at baseline, postintervention, and 1-month follow-up. Results: Completion rates (88%) and satisfaction ratings (10-point scale) were high (LARKSPUR: M = 9.14, standard deviation (SD) = 1.49; control: M = 8.59, SD = 1.97). Improvements were greater in LARKSPUR participants compared with control participants on measures of positive affect (Cohen's d = 0.19 [0.15, 0.24]), negative affect (Cohen's d = -0.07 [-0.11, -0.02]), and pain catastrophizing (Cohen's d = -0.14 [-0.23, -0.05]). Improvements in positive affect (Cohen's d = 0.17 [0.13, 0.22]) and negative affect (Cohen's d = -0.11 [-0.15, -0.06]) were maintained at 1-month follow-up. Dose-response analyses indicated that intervention engagement significantly predicted pre-to-post and post-to-follow-up reductions in pain catastrophizing. Discussion and Implications: The current preliminary findings add to existing literature and highlight the specific potential of internet-delivered positive affect skills programs for adults with FMS. Clinical Trial Registration: NCT04869345.
RESUMEN
Diffuse large B-cell lymphoma (DLBCL) is a heterogenous group of lymphoid malignancies. Based on gene expression profiling, it has been subdivided into germinal center (GC)-derived and activated B-cell (ABC) types. Advances in molecular methodologies have further refined the subclassification of DLBCL, based on recurrent genetic abnormalities. Here, we describe a distinct case of DLBCL that presented in leukemic form. DNA sequencing targeting 275 genes revealed pathogenically relevant mutations of CD79B, MyD88, TP53, TBL1XR1, and PIM1 genes, indicating that this lymphoma would be best classified as MCD/C5 DLBCL, an ABC subtype. Despite an initial good clinical response to BTK inhibitor ibrutinib, anti-CD20 antibody rituxan, alkylating agent bendamustine, and hematopoietic stem-cell transplant, the lymphoma relapsed, accompanied by morphologic and molecular evidence of disease progression. Specifically, the recurrent tumor developed loss of TP53 heterozygosity (LOH) and additional chromosomal changes central to ABC DLBCL pathogenesis, such as PRDM1 loss. Acquired resistance to ibrutinib and rituxan was indicated by the emergence of BTK and FOXO1 mutations, respectively, as well as apparent activation of alternative cell-activation pathways, through copy-number alterations (CNAs), detected by high-resolution chromosomal microarrays. In vitro, studies of relapsed lymphoma cells confirmed resistance to standard BTK inhibitors but sensitivity to vecabrutinib, a noncovalent inhibitor active against both wild-type as well as mutated BTK. In summary, we provide in-depth molecular characterization of a de novo leukemic DLBCL and discuss mechanisms that may have contributed to the lymphoma establishment, progression, and development of drug resistance.

Invasive apocrine carcinoma of the breast is a rare entity with an incidence of 3 or 4 cases per million women. Although apocrine breast cancers may have an aggressive clinical presentation, the 7-year cancer survival rate is the same as non-apocrine cancers. The prognosis of IAC is currently determined by conventional factors such as grade, tumor size, and nodal status. Targeted AR therapy is increasingly adopted with some positive results in clinical trials. This research may result in the development of a tailored treatment for these unusual and rare cancers.

Introduction: The rapid growth of mobile health (mHealth) devices holds substantial potential for improving care and care outcomes in aging adults with chronic non-cancer pain (CNCP), however, research evaluating these devices in older adults remains limited. Objective: To ascertain the feasibility and preliminary efficacy of an mHealth intervention (Mymee) that combines symptom, diet, and behavior tracking via a smartphone application with data analytics to detect associations between symptoms and lifestyle factors along with weekly health coaching sessions to mitigate CNCP in adults 55 years of age and older. Methods: Participants (N = 31) in this pilot study were recruited from one primary care practice in New York City and randomized to an intervention [app + up to 12 health coaching sessions (scheduled approximately once weekly) + usual care] or a control (app + usual care) arm. Feasibility measures included recruitment (proportion of eligible persons who enrolled) and retention rates (proportion of subjects completing a follow-up assessment) as well as adherence with the weekly coaching sessions and logging daily data on the app. Efficacy outcomes (e.g., pain intensity, self-efficacy, disability, anxiety) were assessed at baseline and follow-up (~16 weeks after baseline). Descriptive statistics were obtained and general linear mixed models used for primary analyses. Results: Participants had a mean (standard deviation) age of 67.32 (9.17) and were mostly female (61%). Feasibility outcomes were mixed as evidenced by recruitment and retention rates of 74% and 65%, respectively. The mean number of weekly coaching sessions attended by intervention participants was 6.05 (SD = 5.35), while the average number of days logging data on the app was 44.82 (34.02). We found a consistent trend in favor of the intervention, where pain intensity, affect, and quality of life measures improved considerably more among intervention (vs. control) participants. Finally, the proportion of participants with GAD-7 scores at follow up decreased by 0.35 to 0, whereas controls did not change, a significant effect in favor of the intervention (p = 0.02). Conclusions: This study supports the need for future research that seeks to enhance feasibility outcomes and confirm the efficacy of the Mymee intervention among aging adults with CNCP.
RESUMEN
INTRODUCTION: Seriously ill people with dementia living at home may be particularly vulnerable to disruptions in their care during times of crisis. The study sought to describe care experiences of those receiving home-based primary care in New York City during the COVID-19 pandemic and compare the experiences of people with and without dementia. METHODS: We conducted a retrospective review of all electronic medical record notes between March 1, 2020 and December 30, 2020 among a sample of home-based primary care recipients (n = 228), including all deaths that occurred in the spring of 2020. Drawing from administrative records and using an abstraction tool that included both structured (e.g., documented COVID-19 exposure) and unstructured (e.g., text passage describing caregiver burden) data, we identified salient COVID-19 related care experiences and identified and categorized major disruptions in care. RESULTS: Both people with and without dementia experienced significant disruptions of paid caregiving, family caregiving, and home-based services during the COVID-19 pandemic. While the paid caregivers of people with dementia reported more burden to the home-based primary care team as compared to people without dementia, we found little evidence of differences in quantity or type of COVID-19 related disruptions relative to dementia status. DISCUSSION: While those with dementia have distinct care needs, our findings emphasize the way that dementia may be one piece of a larger clinical picture of serious illness. In order to support all patients with high care needs in crisis, we need to understand the interdependence of clinical care, long-term care, and family caregiving support for older adults and view dementia within the larger context of serious illness and care need.

BACKGROUND: Fibromyalgia syndrome (FMS) is a leading cause of functional limitations and disability for which there is no cure. Positive psychological interventions for improving health have received increasing attention, but evidence of the feasibility, acceptability, and impact of such interventions in adult populations with FMS is limited. OBJECTIVES: To describe the rationale and design of a 5-week, online positive affect skills intervention, LARKSPUR: Lessons in Affect Regulation to Keep Stress and Pain UndeR control. METHODS: FMS participants (N = 90) will be randomized to one of two conditions: (1) LARKSPUR or (2) emotion reporting/attention control. LARKSPUR is an online multicomponent intervention that targets eight skills to help foster positive affect: (1) noticing positive events, (2) savoring positive events, (3) identifying personal strengths, (4) behavioral activation to set and work toward attainable goals, (5) mindfulness, (6) positive reappraisal, (7) gratitude, and (8) acts of kindness. The primary outcomes include feasibility (i.e., recruitment, retention, adherence) and acceptability (i.e., helpfulness, usability, satisfaction). Secondary outcomes include pain intensity and pain interference. SIGNIFICANCE: If feasibility and acceptability metrics are met and reductions in pain outcomes are achieved, we will undertake future efficacy and effectiveness trials of LARKSPUR among older adults with FMS. TRIAL REGISTRATION: NCT04869345.

OBJECTIVES: Olive oil (OO)-based intravenous lipid emulsion (IVLE) may have biological advantages for nutrition and inflammation status compared with soybean oil (SO)-based IVLE. We aimed to compare prealbumin levels during infusion of OO- or SO-based IVLE in patients receiving parenteral nutrition in the acute-care setting. METHODS: In this prospective, noninferiority, double blind randomized controlled efficacy trial, patients received either OO-based or SO-based IVLE after providing consent. Biochemical and nutrition parameters were collected at baseline and at 7 to 10 d after initiation of parenteral nutrition. Results are expressed as means (standard deviations). RESULTS: A total of 210 patients completed the study: 102 patients in the SO-based IVLE group and 108 patients in the OO-based IVLE group. Both groups had a significant increase in prealbumin levels from baseline (SO: 0.10 [0.06] versus 0.15 [0.08] g/L; P < 0.0001; OO: 0.11 [0.06] versus 0.16 [0.08] g/L; P < 0.0001), but mean changes between groups were not different (P = 0.53). OO-based IVLE was noninferior to SO-based IVLE in maintaining or increasing serum prealbumin levels, with 20% as the noninferiority margin at follow-up (least square geometric mean ratio [95% CI], 1.10 [0.83,1.47]; P = 0.50). There was a significant improvement in C-reactive protein levels from baseline within each group (SO: 83.24 [69.72] versus 53.4 [59.78] mg/dL; P < 0.0001; OO: 85.13 [68.14] versus 58.75 [60.11] mg/dL; P = 0.004), but mean changes between the groups were not different (P = 0.836). Mortality, length of stay, and infection rates were not different for both groups. CONCLUSIONS: In this study, OO-based IVLE was not inferior to SO-based IVLE in maintaining or increasing the prealbumin level. The improvement of C-reactive protein levels and other clinical outcomes were not different for both groups.

BACKGROUND: Sub-Saharan Africa carries the highest HIV burden globally. It is important to understand how interventions cost-effectively fit within guidelines and implementation plans, especially in low- and middle-income settings. We reviewed the evidence from economic evaluations of HIV prevention interventions in sub-Saharan Africa to help inform the allocation of limited resources. METHODS: We searched PubMed, Web of Science, Econ-Lit, Embase, and African Index Medicus. We included studies published between January 2009 and December 2018 reporting cost-effectiveness estimates of HIV prevention interventions. We extracted health outcomes and cost-effectiveness ratios (CERs) and evaluated study quality using the CHEERS checklist. FINDINGS: 60 studies met the full inclusion criteria. Prevention of mother-to-child transmission interventions had the lowest median CERs ($1144/HIV infection averted and $191/DALY averted), while pre-exposure prophylaxis interventions had the highest ($13,267/HIA and $799/DALY averted). Structural interventions (partner notification, cash transfer programs) have similar CERs ($3576/HIA and $392/DALY averted) to male circumcision ($2965/HIA) and were more favourable to treatment-as-prevention interventions ($7903/HIA and $890/DALY averted). Most interventions showed increased cost-effectiveness when prioritizing specific target groups based on age and risk. INTERPRETATION: The presented cost-effectiveness information can aid policy makers and other stakeholders as they develop guidelines and programming for HIV prevention plans in resource-constrained settings.
RESUMEN
The American Society of Clinical Oncologists and College of American Pathologists have recently released new guidelines for laboratory testing of HER2 status in breast cancer, which require high levels (95%) of concordance between immunohistochemistry positive (3+) and fluorescence in situ hybridization-amplified cases, and between immunohistochemistry negative (0/1+) and fluorescence in situ hybridization-nonamplified cases; these required levels of concordance are significantly higher than those found in most published studies. We tested the hypothesis that a modification of the HER2 immunohistochemistry scoring system could significantly improve immunohistochemistry and fluorescence in situ hybridization concordance. A total of 6604 breast cancer specimens were evaluated for HER2 status by both immunohistochemistry and fluorescence in situ hybridization using standard methodologies. Results were compared when the standard immunohistochemistry scoring system was replaced by a normalized scoring system in which the HER2 score was derived by subtracting the score on the non-neoplastic breast epithelium from that on the tumor cells. Among the 6604 tumors, using a non-normalized immunohistochemistry scoring system, 267/872 (30.6%) of the immunohistochemistry 3+ cases proved to be fluorescence in situ hybridization nonamplified, whereas using the normalized scoring system only 30/562 (5.3%) of immunohistochemistry 3+ cases proved to be 'false positive'. The concordance rate between immunohistochemistry 3+ and fluorescence in situ hybridization-amplified cases using the normalized scoring method was 94.7%, whereas the concordance using the non-normalized method was only 69.4%. Extremely high concordance between immunohistochemistry and fluorescence in situ hybridization assessment of HER2 status in breast cancer is achievable, but to attain this high level of concordance, modification of the FDA-approved immunohistochemistry scoring system is required.
