Patients with BC and cytopenias who were referred for BMBx between 2002-2018 were identified using the Memorial Sloan Kettering Cancer Center institutional database. Characteristics associated with the risk of t-MN were evaluated by multivariable logistic regression and included in a predictive model. The average area under the receiver operating characteristic curve (AUC) was estimated by 5-fold cross-validation. Of the 206 BC patients who underwent BMBx included in our study, 107 had t-MN. By multivariable analysis, white blood cell count 4-11 K/mcL, absolute neutrophil count (ANC) ≥1.5 K/mcL, hemoglobin ≥12.2 g/dL, red cell distribution width 11.5-14.5%, the presence of bone metastasis and a time from BC diagnosis to BMBx \u003C15 months significantly decreased the likelihood of t-MN. The average AUC was 0.88. We stratified our cohort by bone metastasis and by fi ndings on peripheral smear. In both the subset without bone metastasis (n=159) and in the cohort with no blasts or dysplastic cells on peripheral smear (n=96) our variables had similar effects on the risk of t-MN. Among the 47 patients with bone metastasis, an ANC ≥1.5 K/mcL was the only variable associated with a decreased risk of t-MN. Our fi ndings show that in patients with BC and unexplained cytopenias, clinical and laboratory parameters can predict t-MN and assist clinicians in determining the timing of a BMBx.  \nIntroduction  \nTherapy-related myelodysplastic syndrome (t-MDS) and therapy-related acute myeloid leukemia (t-AML)– collectively known as therapy-related myeloid neoplasms (tMN) – are rare long-term complications of cytotoxic chemotherapy and radiotherapy for both solid tumors and hematologic malignancies (HM) 1 The incidence of t-MN is higher after exposure to DNA-damaging agents, especially alkylators, topoisomerase II-inhibitors, and radiation, all commonly used for the adjuvant and neo-adjuvant treat-  \nment of breast cancer (BC) .2,3 t-MN account for an estimated 10% to 20% of all myeloid neoplasms, and are associated with high risk cytogenetic abnormalities, conveying a poorer prognosis than de novo MDS and AML. As overall BC survival improved over the last several decades, the incidence of t-MN has increased.2,4,5 t-MN occur at a rate of 0.6% to 1. 8% after treatment for BC and the frequency increases bet","cbCaitpJAYHQKHZj","https://ap.wps.com/l/cbCaitpJAYHQKHZj","pdf",910384,"English","# Abstract\n# Introduction\n# Methods\n## Variables","[{\"question\":\"What patient group and clinical question does the study address?\",\"answer\":\"The study evaluates patients with breast cancer who develop unexplained cytopenias and are referred for bone marrow biopsy, aiming to predict therapy-related myeloid neoplasms and support biopsy timing decisions.\"},{\"question\":\"How were therapy-related myeloid neoplasms diagnosed and how were treatments categorized?\",\"answer\":\"Diagnosis was determined from Memorial Sloan Kettering pathology reports categorized using International Working Group criteria for MDS and AML.
