RESUMO
OBJECTIVE: To review the pharmacology, efficacy, and safety of capivasertib for the treatment of adults with hormone receptor-positive, HER2-negative (HR+/HER2-) locally advanced or metastatic breast cancer with 1 or more PIK3CA/AKT1/PTEN alterations. DATA SOURCES: A literature search was conducted using PubMed and MEDLINE databases, published abstracts, and studies from ClinicalTrials.gov between 2003 and February 2024. Keywords included capivasertib, AZD5363, PI3K/AKT/mTOR pathway, and breast cancer. DATA EXTRACTION: All applicable publications, package inserts, meeting abstracts, and clinical trials with capivasertib were reviewed. DATA SYNTHESIS: Capivasertib is a first-in-class inhibitor of 3 isoforms of AKT (AKT-1, AKT-2, and AKT-3) which is an essential component in the PI3K/AKT/mTOR signaling pathway involved in oncogenesis. In the phase III CAPItello-291 trial, capivasertib in combination with fulvestrant (C+F) demonstrated improved progression-free survival (PFS) (7.3 vs 3.1 months) compared with placebo-fulvestrant (P+F) cohort in AKT-altered pathway patients who had progressed through prior aromatase inhibitor. The most common adverse reactions of any grade reported in the C+F group were diarrhea, cutaneous skin reactions, nausea, fatigue, and vomiting. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON WITH EXISTING DRUGS: HR+/HER2- advanced breast cancer patients experience progression following endocrine therapies and cyclin-dependent kinase (CDK) 4/6 inhibitors. Capivasertib is a viable treatment option for patients with PIK3CA/AKT1/PTEN activating mutations following progression on endocrine-based regimens in the metastatic setting or recurrence within 12 months of completing adjuvant therapy. CONCLUSION: Integration of capivasertib into clinical practice is ongoing; intermittent dosing and favorable toxicity are attractive for future novel combination prospective trials.
RESUMO
For patients with localized pancreatic cancer with minimal vascular involvement, optimal survivability requires a multidisciplinary approach of surgical resection and systemic chemotherapy. FOLFIRINOX is a combination chemotherapy regimen that offers promising results in the perioperative and metastatic settings; however, it can cause significant adverse effects. Such toxicity can negatively impact some patients, resulting in chemotherapy discontinuation or surgical unsuitability. In an effort to reduce toxicities and optimize outcomes, this investigation explores the safety and feasibility of substituting liposomal irinotecan (nal-IRI) for nonliposomal irinotecan to improve tumor drug delivery and potentially reduce toxicity. This regimen, NALIRIFOX, has the potential to be both safer and more effective when administered in the preoperative setting.
For patients with pancreatic cancer with little to no cancer near the blood vessels, the best life expectancy usually requires surgery and chemotherapy. FOLFIRINOX is a chemotherapy medicine that offers promising results for both patients getting surgery and for patients with widespread disease. However, it can cause harmful side effects. The side effects can be so bad that the chemotherapy has to be stopped or that surgery is no longer possible. In order to reduce the harmful side effects and improve outcomes, this investigation looks into the safety and practicality of using a different version of one of the medicines. The different version hopes to improve drug delivery and reduce harmful side effects. This regimen, NALIRIFOX, can be safer and more effective in patients awaiting surgery. Clinical Trial Registration: UF-STO-PANC-004 (NCT03483038) (ClinicalTrials.gov).

ABSTRACT: Cardiometabolic disease (CMD) is the most common preventable cause of death in the world. A number of components are included in the spectrum of CMD, such as metabolic syndrome/obesity, hyperglycemia/diabetes, dyslipidemia, and hypertension, which are independently associated with cardiovascular disease risk. These conditions often occur together, and patients with cancer frequently undergo treatments that can generate or worsen CMD. This review highlights and presents mechanistic and epidemiological evidence regarding CMD in 4 categories of anticancer medications, namely, mTOR/PI3K-Akt inhibitors, multitargeted tyrosine kinase inhibitor, immune checkpoint inhibitor therapy, and endocrine therapy. Patients taking these medications need careful monitoring during therapy. There is a role for cardio-oncology and onco-primary care specialists in optimally managing patients at risk to mitigate CMD during treatment with these and other investigational anticancer medications.

Immune checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not clinically effective in immunogenically 'cold' tumors such as pancreatic cancer, prostate cancer and neuroendocrine tumors. Through the inhibition of VEGF, it may be possible to potentiate the effect of immune checkpoint blockade in tumors that have traditionally shown a lack of clinical response to immunotherapy. This signal-seeking, single-arm, prospective clinical trial aims to determine the objective response of tivozanib and atezolizumab in advanced immunogenically cold solid tumors. Clinical Trial Registration: NCT05000294 (ClinicalTrials.gov).
RESUMO
INTRODUCTION: The coronavirus of 2019 pandemic has necessitated vast and rapid changes in the way oncology pharmacy services are delivered around the world. METHODS/AIMS: An international survey of oncology pharmacists and technicians was conducted via the International Society of Oncology Pharmacy Practitioners and collaborating global pharmacy organisations to determine the impact that the coronavirus of 2019 has had on pharmacy service delivery, pharmacy practitioners and oncology practice. RESULTS: The survey received 862 responses from 40 different countries from September to October 2020. The majority of respondents were pharmacists (n = 841, 97.6%), with 24% involved in the direct care of patients with the coronavirus of 2019. Of the survey participants, 55% increased their time working remotely, with remote activities including dispensing, patient assessment/follow-up and attending multi-disciplinary rounds. Respondents reported a 72% increase in the use of technology to perform remote patient interaction activities and that participation in educational meetings and quality improvement projects was reduced by 68% and 44%, respectively. Workforce impacts included altered working hours (50%), cancelled leave (48%) and forced leave/furloughing (30%). During the pandemic, respondents reported reduced access to intensive care (19%) and anti-cancer (15%) medications. In addition, 39% of respondents reported reduced access to personal protective equipment, including N95 masks for chemotherapy compounding. Almost half of respondents (49%) reported that cancer treatments were delayed or intervals were altered for patients being treated with curative intent. A third of practitioners (30%) believed that patient outcomes would be adversely impacted by changes to pharmacy services. Sixty-five percent of respondents reported impacts on their mental health, with 12% utilising support services. CONCLUSION: The coronavirus of 2019 pandemic has altered the way oncology pharmacy services are delivered. These results demonstrate the adaptability of the oncology pharmacy profession and highlight the importance of formal evaluation of the varied practice models to determine the evidence-based practices that enhance pharmacy services and, thus, should be reinstated as soon as practical and reasonable.

LESSONS LEARNED: Preclinical studies have demonstrated that Src inhibition through dasatinib synergistically enhances the antitumor effects of oxaliplatin. In this phase II, single-arm study, FOLFOX with dasatinib in previously untreated patients with mPC only showed only modest clinical activity, with a progressive-free survival of 4 months and overall survival of 10.6 months. Continued investigation is ongoing to better understand the role of Src inhibition with concurrent 5-fluorouracil and oxaliplatin in a subset of exceptional responders. BACKGROUND: Src tyrosine kinase activity is overexpressed in many human cancers, including metastatic pancreatic cancer (mPC). Dasatinib is a potent inhibitor of Src family of tyrosine kinases. This study was designed to investigate whether dasatinib can synergistically enhance antitumor effects of FOLFOX regimen (FOLFOX-D). METHODS: In this single-arm, phase II study, previously untreated patients received dasatinib 150 mg oral daily on days 1-14, oxaliplatin 85 mg/m2 intravenous (IV) on day 1 every 14 days, leucovorin (LV) 400 mg/m2 IV on day 1 every 14 days, 5-fluorouracil (5-FU) bolus 400 mg/m2 on day 1 every 14 days, and 5-FU continuous infusion 2,400 mg/m2 on day 1 every 14 days. Primary endpoint was progression-free survival (PFS) with preplanned comparison to historical controls. RESULTS: Forty-four patients enrolled with an estimated median PFS of 4.0 (95% confidence interval [CI], 2.3-8.5) months and overall survival (OS) of 10.6 (95% CI, 6.9-12.7) months. Overall response rate (ORR) was 22.7% (n = 10): one patient (2.3%) with complete response (CR) and nine patients (20.5%) with partial response (PR). Fifteen patients (34.1%) had stable disease (SD). Nausea was the most common adverse event (AE) seen in 35 patients (79.5%). CONCLUSION: The addition of dasatinib did not appear to add incremental clinical benefit to FOLFOX in untreated patients with mPC.

OBJECTIVES: The emergence of immune checkpoint inhibitors has transformed treatment paradigms for various malignancies. Patients with cancer are at increased risk of complications and hospitalizations from influenza; therefore, it is recommended that they receive inactivated influenza vaccination. However, efficacy and safety of inactivated influenza vaccination in patients receiving immune checkpoint inhibitors is uncertain. The objective of this prospective case series was to evaluate the incidence of immune-mediated adverse events (imAEs) following inactivated influenza vaccination in patients receiving immune checkpoint inhibitors. Changes in cytokine and chemokine levels were also evaluated. METHODS: Patients receiving immune checkpoint inhibitors during the 2017-2018 influenza season were eligible for study participation. Peripheral blood samples were collected prior to administration of inactivated influenza vaccine and two post-vaccination time points. Evaluation of new or worsening imAEs occurred via patient questionnaire and review of medical records for 60 days following inactivated influenza vaccination. Baseline imAEs were evaluated from review of medical records for 60 days prior to inactivated influenza vaccination. Serum cytokines and chemokines were measured using a multiplex Luminex assay. RESULTS: Twenty-four patients were enrolled in this study. Seven patients experienced any grade imAE (one patient having 2) within 60 days following inactivated influenza vaccination. The majority were Grades 1-2, including rash (n = 3), hypothyroidism, myalgia, and colitis (n = 1 each). Two patients experienced severe imAEs (grade 3 nephritis and grade 4 diabetes). No significant changes (p > 0.05) in serum cytokine or chemokine concentrations were observed. CONCLUSIONS: Although small, our study suggests that inactivated influenza vaccine may be safely administered to patients receiving immune checkpoint inhibitors. The majority of imAEs following inactivated influenza vaccination were Grades 1-2 and did not require changes in immune checkpoint inhibitor therapy.

Evidence supports olanzapine for prophylaxis of chemotherapy-induced nausea/vomiting (CINV) for highly emetogenic chemotherapy; however, most studies focus on solid malignancies and single-day regimens. A randomized, double-blinded, placebo-controlled trial was conducted to compare the addition of olanzapine to triplet therapy (fosaprepitant, ondansetron, dexamethasone [FOND-O]) versus triplet therapy alone (FOND) in preventing CINV in hematology patients receiving single-day and multiple-day highly emetogenic chemotherapy and hematopoietic cell transplant (HCT) regimens (NCT02635984). The primary objective of this study was to compare complete response (CR; no emesis and minimal nausea, <25 mm on a 100-mm visual analog scale) during the overall assessment period (chemotherapy days plus 5 days after). Secondary objectives were the number of emesis, number of rescue medications, percent achieving minimal nausea, and percent achieving complete protection (CP; no emesis, rescue antiemetic, or significant nausea), all of which are reported as acute (chemotherapy days), delayed (5 days after chemotherapy), and overall phases. Olanzapine 10 mg or matching placebo were given on each chemotherapy day and 3 days after. Adults with hematologic malignancy receiving HCT regimens of melphalan, BEAM (carmustine, etoposide, cytarabine, melphalan), busulfan (Bu)/cyclophosphamide (Cy), Bu/fludarabine (Flu), Bu/melphalan, FluCy, FluCy-total body irradiation (TBI), etoposide-TBI, and ICE (ifosfamide, carboplatin, etoposide) or 7+3 chemotherapy regimens were included. An estimated 98 patients were required using alpha = .05 and 80% power. No significant differences existed in baseline characteristics between FOND-O (nâ¯=â¯51) and FOND (nâ¯=â¯50) arms. Mean duration of olanzapine was 7.7 days (range, 4 to 11). Discontinuation for possible adverse events occurred in 3 placebo and 0 olanzapine patients. CR was significantly higher for FOND-O in overall (55% versus 26%, Pâ¯=â¯.003) and delayed (60.8% versus 30%, Pâ¯=â¯.001) but not acute (Pâ¯=â¯.13) phases. Significantly more patients receiving FOND-O achieved no more than minimal nausea in overall (Pâ¯=â¯.001) and delayed phases (Pâ¯=â¯.0002), as well as fewer overall mean emesis counts (Pâ¯=â¯.005). CP rates were not different in any assessment phase (P ≥ .05 each). Within the HCT subgroup (nâ¯=â¯64), the CR, CP, and no significant nausea rates were significantly better for FONDO-O in overall and delayed phases (all P < .05). Analysis within the HCT subgroup revealed significant improvement in outcomes in delayed and overall phases with FOND-O in the autologous but not allogeneic cohort. Addition of olanzapine to an NK-1-based triplet antiemetic regimen significantly improved clinically relevant outcomes in the HCT population.

OBJECTIVE: To summarize and evaluate immunotherapy agents targeting programmed cell death protein-1 (PD-1) and programmed death ligand-1 (PD-L1) recently approved for the treatment of metastatic urothelial carcinomas (UC). DATA SOURCES: A literature review was performed using PubMed (2012 to June 2017), the American Society of Clinical Oncology abstract databases (2012 to June 2017 Annual Meetings/symposia), and the America Association for Cancer Research symposia (2012 to June 2017). A search using clinicaltrials.gov was conducted to identify studies for atezolizumab, avelumab, durvalumab, nivolumab, and pembrolizumab. STUDY SELECTION AND DATA EXTRACTION: English language phase I to III studies assessing PD-1 and PD-L1 in UC were incorporated. DATA SYNTHESIS: Atezolizumab, avelumab, durvalumab, nivolumab, and pembrolizumab have demonstrated clinical efficacy with tolerable toxicities in patients with metastatic UC with disease progression following platinum-based chemotherapy. Anti-PD-1/PD-L1 therapies may provide overall survival advantage; these are currently being evaluated in ongoing phase 3 studies. Greater objective response rates seem to be observed in PD-L1-positive patients versus PD-L1-negative patients, but methodologies in this assessment differ among clinical trials. The identification of biomarkers that provide greater insight into patients who positively respond to PD-1/PD-L1 therapies are needed. CONCLUSIONS: Treatment options for metastatic UC have expanded to include PD-1/PD-L1 therapies. These agents should be strongly considered as second-line therapy over single-agent chemotherapy for patients who fail or progress after platinum-based treatment.

Secondary failure of platelet recovery (SFPR) is a serious complication observed in approximately 20% of allogeneic hematopoietic stem cell transplant (HSCT) recipients. Although the standard therapeutic approach has been frequent platelet transfusions, romiplostim, a thrombopoietin receptor agonist, may have utility in treating SFPR. The primary objective of this single-center retrospective analysis was to assess effectiveness of romiplostim for SFPR and to evaluate patient factors which may influence clinical outcomes. The primary outcome measure of response was defined as achievement of platelet count ≥ 50 × 109/L without transfusions for ≥ 7 consecutive days. During the study period, 93 patients underwent HSCT and 13 (13.9%) received romiplostim for SFPR. Seven patients (53.8%) responded to romiplostim, requiring a median of three doses (range 1-6) to achieve independence from platelet transfusions. Disease relapse occurred in 38.5% of all patients, two responders and three nonresponders. Median survival post-HSCT was 753 days among responders and 266 days among nonresponders ( p = 0.0375). No serious adverse events were reported, and rates of graft-versus-host disease did not increase following administration of romiplostim. Thrombopoietin receptor agonists including romiplostim offer a treatment option for persistent thrombocytopenia following HSCT. Positive clinical response to romiplostim post-HSCT is associated with improved outcomes.

PURPOSE: To assess the impact of single-dose fosaprepitant on nausea and emesis after BEAM and high-dose melphalan conditioning regimens for autologous hematopoietic stem cell transplantation. METHODS: In a single-center cohort study patients receiving melphalan containing hematopoietic stem cell transplantation regimens who received a one-time dose of 150 mg IV fosaprepitant (n = 56) were compared to a historical control (n = 70). RESULTS: The primary endpoint of no emesis from melphalan administration through five days afterward was 80% for the fosaprepitant group versus 66% in the control group (p = 0.068). Addition of fosaprepitant demonstrated significant improvement in emetic episodes per patient during the entire assessment period (p = 0.011) and days 1-5 after melphalan (p = 0.045). Fosaprepitant resulted in no substantial nausea during the entire assessment period in 37% of high-dose melphalan patients and 57% of BEAM patients. CONCLUSIONS: Further studies are suggested to investigate the optimal number and timing of doses of fosaprepitant in this setting.

BACKGROUND: In hematopoietic stem cell transplantation (HSCT), patients receive individualized treatment planning in conditioning regimens to prevent unwarranted toxicities while maximizing desired outcomes. The dose of a widely studied agent in this setting, busulfan, can be adjusted based on area under the curve (AUC); however, choice of actual body weight (ABW) versus adjusted body weight (DBW) weight to calculate the initial dose may be critical in attaining goal AUC. OBJECTIVE: To determine which weight best correlates with achievement of goal AUC for patients receiving busulfan conditioning for HSCT. Secondary objectives include evaluation of AUC results with clinical outcomes such as toxicity and survival. METHODS: An institutional review board-approved retrospective analysis was performed on 31 allogeneic HSCT recipients who received intravenous busulfan (Q6H with cyclophosphamide [Bu/Cy] or once daily with fludarabine [Flu/Bu]). RESULTS: Eighteen patients received Flu/Bu (50% ABW, 50% DBW) and 13 received Bu/Cy (23% ABW, 77% DBW). Overall, patients dosed by DBW were more likely to undershoot goal AUC (-12.8% vs. +19.5%, p = 0.018) and require dose increases (+20% vs. -19.9%, p = 0.012) versus those dosed by ABW. Subgroup analysis confirmed these results for Bu/Cy (-23.6% vs. +2.2%, p < 0.001 for goal AUC; +36.2% vs. -4.5%, p = 0.008 for busulfan dose increase), but not Flu/Bu (-0.8% vs. +25.3%, p = 0.123 for goal AUC; +3.4% vs. -25.1%, p = 0.174 for busulfan dose increase). Time to engraftment, progression-free survival, and overall survival were not different between dosing groups (p > 0.05). No patient experienced busulfan-related toxicity. CONCLUSIONS: Further prospective studies are warranted to elucidate which weight is most likely to achieve goal AUC and subsequent optimal patient outcomes.

The University of Florida Health conducted a pragmatic implementation of a pharmacogenetics (PGx) panel-based test to guide medications used for supportive care prescribed to patients undergoing chemotherapy. The implementation was in the context of a pragmatic clinical trial for patients with non-hematologic cancers being treated with chemotherapy. Patients were randomized to either the intervention arm or control arm and received PGx testing immediately or at the end of the study, respectively. Patients completed the MD Anderson Symptom Inventory (MDASI) to assess quality of life (QoL). A total of 150 patients received PGx testing and enrolled in the study. Clinical decision support and implementation infrastructure were developed. While the study was originally planned for 500 patients, we were underpowered in our sample of 150 patients to test differences in the patient-reported MDASI scores. We did observed a high completion rate (92%) of the questionnaires; however, there were few medication changes (n = 6 in the intervention arm) based on PGx test results. Despite this, we learned several lessons through this pragmatic implementation of a PGx panel-based test in an outpatient oncology setting. Most notably, patients were less willing to undergo PGx testing if the cost of the test exceeded $100. In addition, to enhance PGx implementation success, reoccurring provider education is necessary, clinical decision support needs to appear in a more conducive way to fit in with oncologists' workflow, and PGx test results need to be available earlier in treatment planning.

Romiplostim, a thrombopoietin mimetic, is FDA approved for the treatment of thrombocytopenia in patients with refractory immune thrombocytopenia. Given the success of thrombopoietin agonists in the treatment of immune thrombocytopenia, data in other clinical settings are emerging. In the bone marrow transplant setting, secondary failure of platelet recovery and persistent thrombocytopenia are associated with increased mortality. In this case, romiplostim was attempted in a chronic lymphocytic leukemia patient who underwent a matched, unrelated donor, non-myeloablative stem cell transplant. This patient experienced profound thrombocytopenia despite dose escalation. Anti-thrombopoietin or anti-romiplostim antibodies were not detected by specific assays. Furthermore, the patient remains in disease remission with full chimerism. This case demonstrates that heavily pre-treated patients with limited bone marrow reserve may not respond to thrombopoietin agonists.

Pancreatic ductal adenocarcinoma (PDAC) is currently the third leading cause of cancer mortality and the incidence is projected to increase by 2030. Despite recent advances in its treatment, African Americans have a 50-60% higher incidence and 30% higher mortality rate when compared to European Americans possibly resulting from differences in socioeconomic status, access to healthcare, and genetics. Genetics plays a role in cancer predisposition, response to cancer therapeutics (pharmacogenetics), and in tumor behavior, making some genes targets for oncologic therapeutics. We hypothesize that the germline genetic differences in predisposition, drug response, and targeted therapies also impact PDAC disparities. To demonstrate the impact of genetics and pharmacogenetics on PDAC disparities, a review of the literature was performed using PubMed with variations of the following keywords: pharmacogenetics, pancreatic cancer, race, ethnicity, African, Black, toxicity, and the FDA-approved drug names: Fluoropyrimidines, Topoisomerase inhibitors, Gemcitabine, Nab-Paclitaxel, Platinum agents, Pembrolizumab, PARP-inhibitors, and NTRK fusion inhibitors. Our findings suggest that the genetic profiles of African Americans may contribute to disparities related to FDA approved chemotherapeutic response for patients with PDAC. We recommend a strong focus on improving genetic testing and participation in biobank sample donations for African Americans. In this way, we can improve our current understanding of genes that influence drug response for patients with PDAC.

BACKGROUND: Supportive care medication use differences may contribute to racial disparities observed in health-related quality of life in patients with pancreatic cancer. METHODS: In this observation study using the Surveillance, Epidemiology, and End Results-Medicare linked database, we sought to examine supportive care medication use disparities in patients with pancreatic cancer from 2005 to 2017 by race and ethnicity. RESULTS: Among 74,309 patients included in the final analysis, racial and ethnic disparities in the use of supportive care medications were identified. After adjustment for confounding factors and compared with non-Hispanic Whites, minorities had significantly less use of opioids [Black: adjusted OR (aOR), 0.84; 95% confidence interval (CI), 0.79-0.88; Asian: aOR, 0.84; 95% CI, 0.79-0.90), and skeletomuscular relaxants (Black: aOR, 0.90; 95% CI, 0.82-0.99; Hispanic: aOR, 0.82; 95% CI, 0.74-0.91; Asian: aOR, 0.59; 95% CI, 0.51-0.68), and increased use of non-opioid analgesics (Hispanic: aOR, 1.16; 95% CI, 1.01-1.14; Asian: aOR, 1.37; 95% CI, 1.26-1.49). Racial and ethnic minorities had less use of antidepressants (Black: aOR, 0.56; 95% CI, 0.53-0.59; Hispanic: aOR, 0.77; 95% CI, 0.73-0.82; Asian: aOR, 0.47; 95% CI, 0.44-0.51), anxiolytics (Black: aOR, 0.78; 95% CI, 0.74-0.82; Hispanic: aOR, 0.66; 95% CI, 0.62-0.71; Asian: aOR, 0.52; 95% CI, 0.48-0.57), and antipsychotics (Hispanic: aOR, 0.90; 95% CI, 0.82-0.99; Asian: aOR, 0.84; 95% CI, 0.74-0.95). CONCLUSIONS: Racial and ethnic disparities in the use of supportive care medications among patients with pancreatic cancer were observed, with the differences unexplained by sociodemographic factors. IMPACT: Future studies should identify strategies to promote equitable use of supportive care medications among racial minorities and explore factors that may influence their use in these populations.

Background Anthracyclines remain a key treatment for many malignancies but can increase the risk of heart failure or cardiomyopathy. Specific guidelines recommend echocardiography and serum cardiac biomarkers such as BNP (B-type natriuretic peptide) or NT-proBNP (N-terminal proBNP) evaluation before and 6 to 12 months after treatment. Our objective was to evaluate associations between racial and ethnic groups in cardiac surveillance of survivors of cancer after exposure to anthracyclines. Methods and Results Adult patients in the OneFlorida Consortium without prior cardiovascular disease who received at least 2 cycles of anthracyclines were included in the analysis. Multivariable logistic regression was performed to estimate the odds ratios (ORs) and 95% CIs for receiving cardiac surveillance at baseline before anthracycline therapy, 6 months after, and 12 months after anthracycline exposure among different racial and ethnic groups. Among the entire cohort of 5430 patients, 63.4% had a baseline echocardiogram, with 22.3% receiving an echocardiogram at 6 months and 25% at 12 months. Non-Hispanic Black (NHB) patients had a lower likelihood of receiving a baseline echocardiogram than Non-Hispanic White (NHW) patients (OR, 0.75 [95% CI, 0.63-0.88]; P=0.0006) or any baseline cardiac surveillance (OR, 0.76 [95% CI, 0.64-0.89]; P=0.001). Compared with NHW patients, Hispanic patients received significantly less cardiac surveillance at the 6-month (OR, 0.84 [95% CI, 0.72-0.98]; P=0.03) and 12-month (OR, 0.85 [95% CI, 0.74-0.98]; P=0.03) time points, respectively. Conclusions There were significant racial and ethnic differences in cardiac surveillance among survivors of cancer at baseline and following anthracycline-based treatment in NHB and Hispanic cohorts. Health care providers need to be cognizant of these social inequities and initiate efforts to ensure recommended cardiac surveillance occurs following anthracyclines.

Background Cyclin-dependent kinase (CDK) 4 and 6 inhibitors have significantly improved survival in patients with hormone receptor-positive metastatic breast cancer. There are few data regarding the epidemiology of cardiovascular adverse events (CVAEs) with these therapies. Methods and Results Using the OneFlorida Data Trust, adult patients without prior cardiovascular disease who received at least 1 CDK4/6 inhibitor were included in the analysis. CVAEs identified from International Classification of Diseases, Ninth and Tenth Revisions (ICD-9/10) codes included hypertension, atrial fibrillation(AF)/atrial flutter (AFL), heart failure/cardiomyopathy, ischemic heart disease, and pericardial disease. Competing risk analysis (Fine-Gray model) was used to determine the association between CDK4/6 inhibitor therapy and incident CVAEs. The effect of CVAEs on all-cause death was studied using Cox proportional hazard models. Propensity-weight analyses were performed to compare these patients to a cohort of patients treated with anthracyclines. A total of 1376 patients treated with CDK4/6 inhibitors were included in the analysis. CVAEs occurred in 24% (35.9 per 100 person-years). CVAEs were slightly higher in patients who received CKD4/6 inhibitors compared with anthracyclines (P=0.063), with higher death rate associated with the development of AF/AFL or cardiomyopathy/heart failure in the CDK4/6 group. The development of cardiomyopathy/heart failure and AF/AFL was associated with increased all-cause death (adjusted hazard ratio [HR], 4.89 [95% CI, 2.98-8.05]; and 5.88 [95% CI, 3.56-9.73], respectively). Conclusions CVAEs may be more common with CDK4/6 inhibitors than previously recognized, with increased death rates in these patients who develop AF/AFL or heart failure. Further research is needed to definitively determine cardiovascular risk associated with these novel anticancer treatments.
