The clinical heterogeneity of MM arises from multiple genomic events that result in tumour development and progression. Recurring genomic abnormalities including cytogenetic abnormalities, gene mutations and abnormal gene expression profiles in myeloma cells have a strong prognostic power. With the advancement in technologies and the development of novel drugs, the prognostic factors and treatment paradigms of MM have been fast evolving over the past few years. Following the introduction of new highthroughput cytogenomic technologies such as array comparative genome hybridisation (aCGH) or single nucleotide polymorphism array (SNP array) and molecular techniques such as gene expression profiling (GEP) and massively parallel genomic sequencing, the prediction of survival in MM no longer solely depends on conventional cytogenetics and interphase fluorescence in situ hybridisation (iFISH) analysis findings. These new technologies enable screening for all possible chromosomal aberrations and other genomic alterations, identifying each aberration on a case-bycase basis and discovering new aberrations that are relevant in unraveling the tumor cells' complex biology. This in turn allows a better understanding of the disease complexity and heterogeneity. The objective of this review on the genetic architecture of MM is to discuss the latest developments on the cytogenetic/cytogenomic-based risk classification of MM that are currently in use and their prognostic implications.</p>","PeriodicalId":48723,"journal":{"name":"Malaysian Journal of Pathology","volume":"46 3","pages":"379-393"},"PeriodicalIF":0.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142899784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory medicine plays a crucial role in both diagnosing and managing CKD, as diagnosis and staging rely on estimated glomerular filtration rate (GFR) and evaluating albuminuria (or proteinuria). It was evident that the laboratory assessment of CKD in Malaysia is not standardised. In light of this, the Malaysian Association of Clinical Biochemistry CKD (MACB-CKD) Task Force issued a national recommendation for laboratory diagnosis of CKD in 2019. Recently, Kidney Disease: Improving Global Outcomes (KDIGO) updated its recommendations for the diagnosis, evaluation, management, and treatment of CKD. These guidelines incorporate the most recent evidence-based practices to support laboratory professionals in delivering optimal care for individuals with CKD, focusing on critical areas such as estimated GFR (eGFR), albuminuria assessment, and risk stratification. The latest National Institute for Health and Care Excellence (NICE) guidelines on CKD has also incorporated the Kidney Failure Risk Equation (KFRE) as a tool for predicting the likelihood of progression to end-stage kidney disease (ESKD) in CKD patients.

A cone-beam computed tomography revealed a unilocular, well-defined radiolucent lesion periapical to tooth 26. A provisional diagnosis of radicular cyst was given, and the cyst was enucleated under general anaesthesia. Histopathological examination showed a multicystic lesion lined by pseudostratified ciliated columnar epithelium. This case was diagnosed as a surgical ciliated cyst based on the history of previous surgery to the maxillary region, radiographic and histopathological features, which are the three essential features for diagnosis based on the WHO Classification (2022).

Many reviews in the published literature have examined the immune functions of MK-derived platelets. However, relatively few reviews have emphasised on the role of MKs as immune cells. This review gives an overview of MKs, megakaryopoiesis and thrombocytopoiesis, as well as a thorough examination of the evidence that favours MKs as immune cells.
