Using epigenomics, we investigated sequential samples in an <i>SRSF2</i>-mutated MDS and AML cohort with normal karyotype at diagnosis and 1qJT at disease evolution after 5′-azacytidine (AZA). 1qJT breakpoints fell within repetitive DNA at both 1q12 and the translocation partners, namely acrocentrics n. 14, 15, 21, and 22, chromosome 16, and chromosome Y. The global methylome at diagnosis showed hypermethylation at 61% of the differentially methylated regions (DMRs), followed by hypomethylation at 80% of DMRs under AZA, mostly affecting pathways related to immune system, chromatin organization, chromosome condensation, telomere maintenance, rRNA, and DNA repair. At disease evolution, a shift toward hypermethylation, intronic enhancers enrichment and epigenetic involvement of the PI3K/AKT and MAPK signaling emerged. In particular, AKT1 phosphorylation behaved as a hallmark of the progression.

However, rare examples of osteosarcomas remain challenging due to unusual histology, such as sclerosing or osteoblastoma-like features, which may require molecular confirmation of their complex genetic alterations. We have encountered such a case in a 17-year-old man, who presented with a third metatarsal sclerotic bone lesion, found incidentally in the work-up of a foot trauma. The initial imaging revealed a lesion with sclerotic/blastic features proximally and lucent/lytic portion distally, findings interpreted consistent with osteoblastoma. The lesion was managed intra-lesionally with curettings and cryoablation; however, the microscopic findings were non-specific, showing a bland osteoblastic proliferation embedded in a densely sclerotic matrix. Subsequently, the patient developed two rapid recurrences; the first recurrence was treated similarly despite its associated soft tissue extension radiographically, and the histologic findings remained non-specific. The 2nd recurrence showed a large mass, with bone destruction and soft tissue extension and an open biopsy revealed features of osteosarcoma with lace-like osteoid deposition, albeit with uniform cytomorphology. The subsequent below knee amputation showed features compatible with high-grade osteosarcoma, including solid growth of uniform epithelioid cells, with vesicular nuclei and scant cytoplasm, set in a lace-like meshwork of osteoid matrix. There was significant mitotic activity and tumor necrosis. Tumor cells were positive for SATB2. Further molecular work-up was performed showing an unexpected <i>NIPBL::BEND2</i> fusion, which has been previously reported in two cases of phosphaturic mesenchymal tumor (PMT). FGF23 (ISH) was performed and was negative. By DNA methylation profiling, unsupervised clustering and UMAP dimensionality reduction revealed grouping with high-grade osteosarcomas and not with the PMT group. The patient received chemotherapy post-amputation and is alive without evidence of disease, with 10-month follow-up. We report an aggressive, overtly malignant acral bone-forming tumor, harboring a <i>NIPBL::BEND2</i> fusion.

The objective of this study is to conduct a systematic review on the characteristics of tumor cells' energy metabolism, with a specific focus on comparing abnormalities between tumor and normal cells, as well as summarizing potential targets for tumor therapy. Additionally, this review also elucidates the aberrant mechanisms underlying four major energy metabolic pathways (glucose, lipid, glutamine, and mitochondria-dependent) during carcinogenesis and tumor progression. Through the utilization of graphical representations, we have identified anomalies in crucial energy metabolism pathways, encompassing transporter proteins (glucose transporter, CD36, and ASCT2), signaling molecules (Ras, AMPK, and PTEN), as well as transcription factors (Myc, HIF-1α, CREB-1, and p53). The key molecules responsible for aberrant energy metabolism in tumors may serve as potential targets for cancer therapy.
