The lived experience of patients with breast cancer on adjuvant endocrine therapy: side effects and coping strategies during the first year of medication initiation.

PURPOSE: Adjuvant endocrine therapy (AET) is pivotal for hormone receptor-positive breast cancer patients, significantly enhancing survival rates. Yet, adherence to AET remains challenging due to side effects. This study delves into the lived experience of breast cancer survivors concerning AET-induced side effects and examines differences in symptom profiles between Tamoxifen and aromatase inhibitors (AIs). METHODS: We interviewed 35 breast cancer survivors on AET, conducting qualitative iterative analysis using grounded theory. A codebook was developed to aid data coding and interpretation. NVIVO software facilitated comprehensive transcript analysis. RESULTS: Survivors reported a spectrum of side effects like hot flashes, sexual issues, joint pain, stiffness, mood swings, and fertility concerns. Symptom profiles differed based on AET type. Tamoxifen users experienced more frequent sexual side effects and mood swings, while AIs were linked to joint pain, stiffness, and bone health worries. Those on AET for over 6 months expressed heightened concerns about side effects. CONCLUSION: Tailored patient education, aligned with AET type, empowers survivors to manage side effects using self-regulatory strategies. Acknowledging distinct symptom profiles enables informed decisions, improving adherence and quality of life. IMPLICATIONS: This study underscores tailored survivorship support, equipping patients with tools to manage side effects, enhancing adherence, and long-term outcomes. The findings inform the integration of comprehensive survivorship programs, emphasizing individualized strategies for managing side effects and promoting better adherence and improved quality of life.

Autologous fat grafting as a novel technique for primary essential cutis verticis gyrata.

Background: Cutis verticis gyrata (CVG) is a condition of excessive skin growth and excessive laxity of the scalp, leading to deep furrows and folds that resemble the gyri and outer surface of the brain. Approaches for the treatment of CVG range from conservative to surgical, the last one being the predominant way of treating the condition, however, the surgery proposed in the recent literature may not be suitable for patients who desire a less invasive approach. Aim: To report the first case of autologous fat injection as a novel treatment option for primary essential CVG. Methods: A 51 -year-old Colombian man, with no medical records was treated with a scalp injection of autologous fat, with previous failed treatment with pressure therapy apply directly on skin is described. Results: A successful cosmetic improvement and a less invasive approach was reached after two sessions of autologous fat grafting. Conclusion: This method allowed excellent cosmetic outcomes while preserving the option of subsequent surgical repair in refractory cases.

The lived experience of breast cancer patients on adjuvant endocrine therapy: Side effects and coping strategies during the first year of medication initiation.

Purpose: Breast cancer in women is the most commonly diagnosed cancer. Adjuvant endocrine therapy (AET) showed consistent improvements in recurrence and survival rates. Adherence to adjuvant endocrine therapy remains essential for improving overall survival in women with hormone receptor (HR) positive breast cancer. However, early discontinuation of medicine is reported to range from 20% to 50%. Poor adherence has been attributed to multiple factors including presence of adverse events. We aim to report the lived experience of breast cancer survivors specifically as regards to side effects, the most reported reason for lack of adherence. Methods: 35 breast cancer survivors on AET were interviewed. Qualitative iterative analysis was conducted using the grounded theory approach with the goal of identifying themes that emerge from the interviews and refining the question probes as needed. A codebook was developed and supplemented with interpretive codes generated through ongoing analysis of transcripts. All transcripts were coded using NVIVO qualitative data analysis software for data interpretations. Results: Reported side effects associated with AET medications include hot flashes, sexual side-effects, joint pain, stiffness, cognitive function, mood changes, bone mass density decrease and fertility concerns. Women who were on AET more than 6 months reported more side effect concerns. A variety of coping strategies using over the counter medications or alternative medicines and approaches were also discussed. Conclusion: Tailored and timely information on potential AET-induced side effects and strategies to manage them is needed. In particular, some side effects are more prevalent by medication (e.g., joint pain in those who were taking an aromatases inhibitor). Provision of information to prepare women for the potential side effects of type of AET they are prescribed for would be helpful. Implications for Cancer Survivors: As AET has been suggested for 10 years to improve surveillance and reduce recurrence, our results have implications for cancer survivors, especially the onsets of side effects and potential ways to manage them as they arise.

Increasing equitable access to telehealth oncology care in the COVID-19 National Emergency: Creation of a telehealth task force.

INTRODUCTION: Telehealth (TH) utilization in cancer care prior to COVID-19 was variable. Research highlights disparities in access determined by socioeconomic factors including education, income, race, and age. In response to COVID-19 and these disparities, we assessed the impact of a personalized digital support structure, the Telehealth Task Force (TTF), to reduce disparities in TH. METHODS: We performed a retrospective review of cohorts between January 1, 2020 and August 30, 2020: Pre (TH use with basic telephone support), Intervention (TH access with TTF), and Post (TH access after TTF initiation and educational material dissemination). Data collected included successful TH access, health literacy (HL), and Area Deprivation Index, a ranking of neighborhoods by socioeconomic disadvantage (ADI). The data were analyzed in univariate ordinary least squares model and adjacent categories ratio model using statistical software R to understand the relationship between TTF, HL, ADI, and TH access. RESULTS: We included 555 patients from January 1, 2020 to August 30, 2020 (90 preintervention, 194 intervention, and 271 postintervention), excluding patients without ADI/HL. TTF support successfully engaged older, racially, and socioeconomically diverse patients in TH; ADI is significantly higher in the postintervention group vs. preintervention (mean difference = 7.66, 95% CI 1.00-4.32, p = 0.024) and more patients had low HL during intervention compared with preintervention (adjacent categories ratio = 0.62, 95% CI 0.41-0.93, p = 0.021). DISCUSSION: COVID-19 created an immediate need for TH. Implementation of the TTF helped close the digital divide, increasing TH access for vulnerable patients. Attention to digital readiness can mitigate disparities in access to care. Future research should explore the implementation of widespread routine digital support initiatives.

Genomic Aberrations in Circulating Tumor DNAs from Palbociclib-Treated Metastatic Breast Cancer Patients Reveal a Novel Resistance Mechanism.

Previously undescribed molecular mechanisms of resistance will emerge with the increased use of cyclin-dependent kinase 4/6 inhibitors in clinical settings. To identify genomic aberrations in circulating tumor DNA associated with treatment resistance in palbociclib-treated metastatic breast cancer (MBC) patients, we collected 35 pre- and post-treatment blood samples from 16 patients with estrogen receptor-positive (ER+) MBC, including 9 with inflammatory breast cancer (IBC). Circulating cell-free DNAs (cfDNAs) were isolated for sequencing using a targeted panel of 91 genes. Our data showed that FBXW7 and CDK6 were more frequently altered in IBC than in non-IBC, whereas conversely, PIK3CA was more frequently altered in non-IBC than in IBC. The cfDNA samples collected at follow-up harbored more mutations than baseline samples. By analyzing paired samples, we observed a higher percentage of patients with mutations in RB1, CCNE1, FBXW7, EZH2, and ARID1A, but a lower proportion of patients with mutated TSC2 at the post-treatment stage when they developed progression. Moreover, acquisition of CCNE1 mutations or loss of TSC2 mutations after treatment initiation conferred an unfavorable prognosis. These data provide insights into the relevance of novel genomic alterations in cfDNA to palbociclib resistance in MBC patients. Future large-scale prospective studies are warranted to confirm our findings.

Genetic Evaluation for Hereditary Cancer Syndromes Among African Americans: A Critical Review.

While hereditary cancer syndromes have been described and studied for centuries, the completion of the human genome project fueled accelerated progress in precision medicine due to the introduction of genetic testing in the 1990s, creating avenues for tailored treatments and medical management options. However, genetic testing has not benefited everyone equitably, with nearly all of the published work based on individuals of non-Hispanic White/European ancestry. There remains a gap in knowledge regarding the prevalence, penetrance, and manifestations of common hereditary cancer syndromes in the African-American population due to significant disparities in access and uptake of genetic testing. This review summarizes the available literature on genetic testing for breast, colon, and prostate cancers in the African-American population and explores the disparities in access to genetic testing between non-Hispanic White and African-American patients. This article also addresses the barriers to genetic testing and discrepancies in the uptake of recommendations for hereditary cancer syndromes in the African-American population when compared with non-Hispanic Whites. The review offers practice implications for many healthcare providers and demonstrates gaps in the existing knowledge to be addressed in future studies to help eliminate the persisting health disparities faced by the African-American population.

Design and validation of quality indicators for drug dispensing in a pediatric hospital.

OBJECTIVES: This article presents a methodological strategy to design and validate quality indicators for drug dispensing in a pediatric hospital. SETTING: The literature evaluation, design, and validation of indicators by experts were carried out from September 2017 to March 2018 in the pharmaceutical services of a pediatric hospital at the Autonomous University of the State of Hidalgo, Mexico. PRACTICE DESCRIPTION: The design and validation of quality indicators for dispensing allow the evaluation, planning, and follow-up of this activity. PRACTICE INNOVATION: The development of the indicators follows a holistic vision considering the relationship between the structure on which the pediatric dispensation is based, the involved processes, and the outcomes and provide a simple tool to improve the quality of the dispensing service. EVALUATION: A methodological investigation for the development of systems and health services in drug dispensing was performed. For the indicator's design, the Mexican standards for establishments dedicated to the sale and supply of drugs, the Good Dispensation Practices, and the Donabedian model were considered. The validation of such indicators was carried out using the Delphi method and the Torgerson mathematical model. RESULTS: Indicators of structure, process, and results were designed; of the 16 indicators designed, 15 reached the average score of greater than 3.5, and the percentage of experts who qualified each indicator in the highest categories was greater than 50%. CONCLUSION: The design of indicators guarantees the quality of the dispensing service and can be extrapolated to the pharmaceutical services of any pediatric hospital.

Prognostic value of HER2 status on circulating tumor cells in advanced-stage breast cancer patients with HER2-negative tumors.

PURPOSE: Discordance between HER2 expression in tumor tissue (tHER2) and HER2 status on circulating tumor cells (cHER2) has been reported. It remains largely underexplored whether patients with tHER2-/cHER2+ can benefit from anti-HER2 targeted therapies. METHODS: cHER2 status was determined in 105 advanced-stage patients with tHER2- breast tumors. Association between cHER2 status and progression-free survival (PFS) was analyzed by univariate and multivariate Cox models and survival differences were compared by Kaplan-Meier method. RESULTS: Compared to the patients with low-risk cHER2 (cHER2+ < 2), those with high-risk cHER2 (cHER2+ ≥ 2) had shorter survival time and an increased risk for disease progression (hazard ratio [HR] 2.16, 95% confidence interval [CI] 1.20-3.88, P = 0.010). Among the patients with high-risk cHER2, those who received anti-HER2 targeted therapies had improved PFS compared with those who did not (HR 0.30, 95% CI 0.10-0.92, P = 0.035). In comparison, anti-HER2 targeted therapy did not affect PFS among those with low-risk cHER2 (HR 0.70, 95% CI 0.36-1.38, P = 0.306). Similar results were obtained after adjusting covariates. A longitudinal analysis of 67 patients with cHER2 detected during follow-ups found that those whose cHER2 status changed from high-risk at baseline to low-risk at first follow-up exhibited a significantly improved survival compared to those whose cHER2 remained high-risk (median PFS: 11.7 weeks vs. 2.0 weeks, log-rank P = 0.001). CONCLUSION: In advanced-stage breast cancer patients with tHER2- tumors, cHER2 status has the potential to guide the use of anti-HER2 targeted therapy in patients with high-risk cHER2.

Disparities in cancer survival and incidence by metropolitan versus rural residence in Utah.

Cancer disparities in rural and frontier communities are an important issue in Utah because much of Utah is sparsely populated. The aims of this study were to investigate whether there are differences in the cancer incidence and 5-year survival rates in Utah by metropolitan/rural residence and to investigate disparities in distributions of cancer risk factors. We used cancer registry records to identify patients diagnosed with a first primary cancer in Utah between 2004 and 2008. We estimated 5-year survival and incidence rates. The Cox proportional hazards model was used to estimate hazard ratios (HRs) for the risk of death. There were 32,498 (86.9%) patients with cancer who lived in metropolitan counties and 4906 (13.1%) patients with cancer who lived in rural counties at the time of cancer diagnosis. Patients with cancer from rural counties were more likely to be older, American Indian/Alaskan Native, non-Hispanic, male, and diagnosed at higher stage. Rural residents had a five-year relative survival that was 5.2% lower than metropolitan residents and a 10% increase in risk of death (HR = 1.10, 95% CI = 1.03, 1.18) after adjustment for multiple factors. Overall, the cancer incidence rates in rural counties were lower by 11.9 per 100,000 per year (449.2 in rural counties vs. 461.1 in metropolitan counties). Cancer patients living in rural counties of Utah had different demographic characteristics as well as differences in incidence and survival rates. Further studies with individual-level data are necessary to investigate the reasons behind these differences in cancer incidence and survival to reduce disparities.

Efficacy of simulated cefditoren versus amoxicillin-clavulanate free concentrations in countering intrastrain ftsI gene diffusion in Haemophilus influenzae.

This study explores the effects of cefditoren (CDN) versus amoxicillin-clavulanic acid (AMC) on the evolution (within a single strain) of total and recombined populations derived from intrastrain ftsI gene diffusion in ß-lactamase-positive (BL⁺) and ß-lactamase-negative (BL⁻) Haemophilus influenzae. DNA from ß-lactamase-negative, ampicillin-resistant (BLNAR) isolates (DNA(BLNAR)) and from ß-lactamase-positive, amoxicillin-clavulanate-resistant (BLPACR) (DNA(BLPACR)) isolates was extracted and added to a 107-CFU/ml suspension of one BL⁺ strain (CDN MIC, 0.007 µg/ml; AMC MIC, 1 µg/ml) or one BL⁻ strain (CDN MIC, 0.015 µg/ml; AMC MIC, 0.5 µg/ml) in Haemophilus Test Medium (HTM). The mixture was incubated for 3 h and was then inoculated into a two-compartment computerized device simulating free concentrations of CDN (400 mg twice a day [b.i.d.]) or AMC (875 and 125 mg three times a day [t.i.d.]) in serum over 24 h. Controls were antibiotic-free simulations. Colony counts were performed; the total population and the recombined population were differentiated; and postsimulation MICs were determined. At time zero, the recombined population was 0.00095% of the total population. In controls, the BL⁻ and BL⁺ total populations and the BL⁻ recombined population increased (from ≈3 log10 to 4.5 to 5 log10), while the BL⁺ recombined population was maintained in simulations with DNA(BLPACR) and was decreased by ≈2 log10 with DNA(BLNAR). CDN was bactericidal (percentage of the dosing interval for which experimental antibiotic concentrations exceeded the MIC [ft>MIC], >88%), and no recombined populations were detected from 4 h on. AMC was bactericidal against BL⁻ strains (ft>MIC, 74.0%) in DNA(BLNAR) and DNA(BLPACR) simulations, with a small final recombined population (MIC, 4 µg/ml; ft>MIC, 30.7%) in DNA(BLPACR) simulations. When AMC was used against the BL⁺ strain (in DNA(BLNAR) or DNA(BLPACR) simulations), the bacterial load was reduced ≈2 log10 (ft>MIC, 44.3%), but 6.3% and 32% of the total population corresponded to a recombined population (MIC, 16 µg/ml; ft>MIC, 0%) in DNA(BLNAR) and DNA(BLPACR) simulations, respectively. AMC, but not CDN, unmasked BL⁺ recombined populations obtained by transformation. ft>MIC values higher than those classically considered for bacteriological response are needed to counter intrastrain ftsI gene diffusion by covering recombined populations.
