Abstract
We have previously recognized the genotypic and prognostic heterogeneity of U2AF1 mutations (MT) in myelofibrosis (MF) and myelodysplastic syndromes (MDS). In the current study, we considered 179 U2AF1-mutated patients with clonal cytopenia of undetermined significance (CCUS; n = 22), MDS (n = 108), MDS/acute myeloid leukemia (AML; n = 18) and AML (n = 31). U2AF1 variants included S34 (60%), Q157 (35%), and others (5%): corresponding mutational frequencies were 45%, 55%, and 0% in CCUS; 57%, 39%, and 4% in MDS; 61%, 33%, and 6% in MDS/AML; and 55%, 35% and 10% in AML (P = 0.17, 0.36 and 0.09), respectively. Concurrent mutations included ASXL1 (37%), BCOR (19%), RUNX1 (14%), TET2 (15%), DNMT3A (10%), NRAS/KRAS (8%), TP53 (8%), JAK2 (5.5%) and SETBP1 (5%). The two most frequent U2AF1 MT were S34F (n = 97) and Q157P (n = 46); concurrent MT were more likely to be seen with the latter (91% vs 74%; P = 0.01) and abnormal karyotype with the former (70% vs 62%; P = 0.05). U2AF1 S34F MT clustered with BCOR (P = 0.04) and Q157P MT with ASXL1 (P = 0.01) and TP53 (P = 0.03). The median overall survival (OS) in months was significantly worse in AML (14.2) vs MDS/AML (27.3) vs MDS (33.7; P = 0.001); the latter had similar OS with CCUS (30.0). In morphologically high-risk disease (n = 49), defined by ≥10% blood or bone marrow blasts (i.e., AML or MDS/AML), median OS was 14.2 with Q157P vs 37.1 months in the presence of S34F (P = 0.008); transplant-adjusted multivariable analysis confirmed the detrimental impact of Q157P (P = 0.01) on survival and also identified JAK2 MT as an additional risk factor (P = 0.02). OS was favorably affected by allogeneic hematopoietic stem cell transplantation (HR: 0.16, 95% CI; 0.04-0.61, P = 0.007). The current study defines the prevalence and co-mutational profiles of U2AF1 pathogenic variants in AML, MDS/AML, MDS, and CCUS, and suggests prognostic heterogeneity in patients with ≥10% blasts.

Abstract
INTRODUCTION Intrathoracic extravasation of anthracyclines is a dangerous and very rare complication of chemotherapy administration. While management of extravasation into soft tissues has been established, the data on treatment of mediastinal and intrapleural anthracycline extravasation is limited. CASE REPORT We present a case of a 52-year-old woman with intrapleural doxorubicin extravasation who presented to the hospital 24-hrs after chemotherapy infusion with chest pain and shortness of breath. MANAGEMENT & OUTCOME The patient underwent urgent surgical intervention and received IV dexrazoxane 36-hrs after the event. Her pain improved, but she continued to have chest soreness and pleural effusion at the site of extravasation even 3 months later. DISCUSSION We conducted review of literature using Medline/PubMed and Google Scholar databases and identified 7 cases of intrapleural and mediastinal anthracycline extravasation. No data is currently available regarding the outcome of delayed management of intrapleural anthracycline extravasation with dexrazoxane. Prevention and confirmation of adequate port catheter placement is the most important step to avoid such cases. Catheter misplacement should be suspected in any patient presenting with post procedural chest pain and should trigger a thorough evaluation prior to any chemotherapy administration.
