In Brazil, as well as in other countries, procarbazine has been replaced with dacarbazine due to the limited availability of procarbazine. The Hematology Center at Irmandade da Santa Casa de Misericórdia in São Paulo adopted and modified the escalated BEACOPP protocol, substituting prednisone with dexamethasone and incorporating two different doses of dacarbazine: 375 mg/m<sup>2</sup>/day on Day 8 or the original dose of 250 mg/m<sup>2</sup>/day on Days 2 and 3. This adjustment was made in response to the anticipated toxicity profile. This study aimed to compare the two different doses in the protocols (375 mg/m<sup>2</sup>/cycle versus 500 mg/m<sup>2</sup>/cycle) administered to patients with advanced Hodgkin's lymphoma in similar periods. This retrospective study analyzed the data of 31 patients at a single center in Brazil from 2019 to 2021. Seventeen of the 31 patients received 500 mg/m<sup>2</sup>/cycle (500 Group), while 14 received 375 mg/m<sup>2</sup>/cycle (375 Group). At the end of the protocol, 71% of the patients in the 375 Group and 76% in the 500 Group achieved complete remission. On analyzing the number of cycles that patients presented with febrile neutropenia, the 500 Group had three times more events (17.9%) than the 375 Group (6.09% - p-value = 0.04). In the 500 Group, 47.1% needed to change the protocol to ABVD (doxorubicin hydrochloride, bleomycin sulfate, vinblastine sulfate, and dacarbazine) due to toxicity. In this limited cohort from a single public center in Brazil, the use of 375 mg/m<sup>2</sup> of dacarbazine per cycle of the modified escalated BEACOPP protocol emerged as a safer strategy, maintaining treatment efficacy without compromising response in patients with advanced Hodgkin's lymphoma.</div></div>","PeriodicalId":12958,"journal":{"name":"Hematology, Transfusion and Cell Therapy","volume":"47 1","pages":"Article 103682"},"PeriodicalIF":1.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142304631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disruptive innovation is a process where technology, products, or services are transformed or replaced by a better innovative solution. This superiority must be perceived by users as being more accessible, simple, or convenient. Patient Blood Management (PBM) suggests the notion of the timely application of evidence-based medical and surgical concepts designed to maintain hemoglobin concentration, optimize hemostasis and minimize blood loss thus improving patient outcomes, that is, they are aimed at changing patient care, assisting healthcare professionals in disease treatment and cure as well as risk reduction. Thus, innovation in PBM is a new frontier to be pursued. The management of patient's blood and preparation for surgical procedures is an enormous challenge that helps minimize anemia and control blood loss during hospitalization, ensuring they are discharged in adequate clinical conditions. Until 2016, there was no standard definition or classification for the severity of intraoperative bleeding or hemostasis. The development of a PBM program when combined to the development of a bleeding scale such as the validated Intraoperative Bleeding (VIBe) Scale, represents a new solution that balances perioperative blood loss and more importantly, enables a critical cultural change which can be useful to help surgeons communicate anticipated hemostatic needs throughout a case and therefore enhance efficiency leading to better outcomes.</div></div>","PeriodicalId":12958,"journal":{"name":"Hematology, Transfusion and Cell Therapy","volume":"47 1","pages":"Article 103691"},"PeriodicalIF":1.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142304649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diagnosis of AML requires a careful evaluation of clinical morphology, immunophenotyping, cytogenetics, and molecular analyses. <sup>1</sup> In current practice, flow cytometry-based immunophenotyping provides a rapid and reliable method for diagnosing AML, including acute promyelocytic leukemia (APL). APL is a subtype of AML with distinct morphological, biological, and clinical characteristics. It can be effectively treated with ATRA-based therapy protocols. However, if not treated quickly, it can be fatal due to the risk of disseminated intravascular coagulation (DIC). Therefore, the diagnosis and treatment of APL represent a true medical emergency.<sup>2</sup></div><div>The absence of CD34, HLA-DR, and CD11b is a characteristic immunophenotypic feature that often distinguishes APL from other AML subtypes. However, AML subtypes other than APL that lack CD34 and HLA-DR expression have also been reported. APL accounts for 8% to 17% of AML patients. In AML patients without the PML-RARA fusion gene, 12% to 21% of cases have been identified as HLA-DR negative. These HLA-DR negative AML cases are distinct from APL because they do not carry the characteristic PML-RARA fusion.<sup>3</sup></div><div>HLA-DR and CD34 negativity is generally observed in AML-M1 and AML-M2 subtypes and is associated with nucleophosmin (NPM1) gene mutations and FMS-like tyrosine kinase-internal tandem duplication (FLT3-ITD) mutations.<sup>4</sup> NPM1 mutations are among the most common genetic abnormalities in AML, occurring in 27-35% of adult AML cases.
