CircMYBL1 Suppressed Acquired Resistance to Osimertinib in Non-Small-Cell Lung Cancer
Lung cancer is one of the top five cancer types diagnosed globally, accounting for 11.4% of all cancer cases in 2020, and non-small cell lung cancer (NSCLC) accounts for approximately 80 –85% of cases [1]. Following the decoding of human cancer genome, new therapeutic strategies have emerged in recent years, including targeted therapy against driver mutations, and immunotherapy, which significantly improve patient outcomes. Epidermal growth factor receptor (EGFR) mutations are the most common actionable driver mutations found in patients with NSCLC, and are present in 10–30% of all NSCLC cases [2–4]. (Source: Cancer ...

Assessment for 11q and other chromosomal aberrations in large B-cell/high-grade B cell lymphomas of germinal center phenotype lacking BCL2 expression
The aggressive B-cell lymphomas include multiple entities with differences in morphology, phenotype, molecular pathogenesis, and clinical behavior. Of the large B cell lymphomas within this category, those that show germinal center (GC) phenotype but lack BCL2 expression include (among others) diffuse large B cell lymphoma, not otherwise specified (DLBCL NOS), a proportion of cases of high-grade B cell lymphoma, NOS (HGBCL, NOS), and high-grade B cell lymphomas with 11q aberration (HGBL-11q, WHO 5th edition).

Upregulation of shelterin and CST genes and longer telomeres are associated with unfavorable prognostic characteristics in prostate cancer.
Prostate cancer (PC) is one of the most diagnosed cancers in men and is a severe public health problem worldwide [1,2]. A peculiar feature of PC is the fact of its immense heterogeneity and genetic instability, which makes it challenging to classify into well-defined molecular subtypes [3]. In practical terms, because of this heterogeneity, classical prognostic factors, such as serum PSA and ISUP score, are not accurate enough to distinguish aggressive from indolent tumors early [4 –7]. Added to this, we know that damage caused by excessive treatment and diagnosis is a real problem in PC since while the vast majority of ...

Rare NUP98::PRRX1 fusion transcript in a therapy-related acute myeloid leukemia associated with del(7q) following chemotherapy for diffuse large B-cell lymphoma
Therapy-related acute myeloid leukemia (t-AML) is a serious adverse consequence in cancer treatment, including chemotherapy, radiation therapy, or immunosuppressive agents, accounting for 7% of adult AML [1,2]. The two most common leukemia-causing cytotoxic drugs include alkylating agents and topoisomerase-II inhibitors. The majority of alkylating agents-related leukemias have a longer latency of 5 –10 years and typically have a total or partial deletion of chromosome 5 [-5/del(5q)] and chromosome 7 [-7/del(7q)] and/or complex karyotype and are often present with prior myelodysplastic syndrome (MDS) and poor prognosis.

Successful treatment of the first adult case of ZMIZ1::ABL1-positive B cell lymphoblastic leukemia with dasatinib, chimeric antigen receptor T-cell therapy, and allogeneic hematopoietic stem cell transplantation
BCR::ABL1-like B cell lymphoblastic leukemia (B-ALL) is characterized by a gene-expression profile similar to that of BCR::ABL1-positive B-ALL, alterations of lymphoid transcription factor genes, and a poor outcome [1]. Kinase fusions are one of the most critical genetic features for this high-risk disease, and their detection may benefit the patients from targeted tyrosine kinase inhibitor (TKI) therapy [2]. BCR::ABL1-like B-ALL was initially introduced as a provisional entity in the revised 4th edition of the World Health Organization (WHO) Classification of Haematolymphoid Tumours [3].

Aggressive systemic mastocytosis with the co-occurrence of PRKG2::PDGFRB, KAT6A::NCOA2, and RXRA::NOTCH1 fusion transcripts and a heterozygous RUNX1 frameshift mutation
Systemic mastocytosis (SM) is a rare myeloproliferative neoplasm characterized by abnormal mast cell (MCs) clonal proliferation and accumulation in organ systems. It is diagnosed based on the WHO2016 criteria and divided into different forms [1], including aggressive systemic mastocytosis (ASM), accounting for less than 10% of all SM cases and included among the “advanced SM”. ASM has bone marrow (BM) smear with (Source: Cancer Genetics and Cytogenetics)

Simultaneous occurrence of multiple myeloma and acute myeloid leukemia: case report and literature review
Multiple myeloma (MM) and acute myeloid leukemia (AML) are malignant clonal diseases of cells in different lineages. It remains very rare to have both diseases at first diagnosis. Only 24 cases of this situation were reported from 1971 to 2021, and poor prognosis in most cases. However, here we describe a case of de novo MM and AML occurring simultaneously in a 65-year-old woman. We have successfully used individualized treatment regimens to allow the patient to survive 1.5 years to date, which has exceeded 80% of statistical cases. (Source: Cancer Genetics and Cytogenetics)

EML4-ALK Variant 3a/b as a mechanism of osimertinib resistance in a patient with EGFR L858R positive NSCLC
In September 2019, a 74-year-old woman was introduced to our hospital because of persistent right chest pain. She had a history of smoking (50 pack-years) and had undergone surgery for right breast cancer at 40 years of age without recurrence. Chest computed tomography (CT) revealed a mass in the upper lobe of the right lung (Figure 1A). She underwent CT-guided lung biopsy and was diagnosed with lung adenocarcinoma stage IVB (cT4N2M1c) with multiple lung and bone metastases. Bone metastases were detected in the transverse processes of the thoracic spine on PET at diagnosis; however, the effect of treatment was difficult to...
