Liposarcoma

ATRX mutational status may serve as a potential biomarker for prognosis and therapeutic stratification. Future clinical trials investigating epigenetic therapies could offer novel treatment strategies for ATRX-deficient sarcomas.

Furthermore, we identify a synergistic antitumor effect between KPT-330 and translation inhibitors, including everolimus and homoharringtonine. Notably, the disruptive impact of KPT-330 on CRC homeostasis extends to other cancer cell lineages, underscoring its broad mechanistic relevance. Collectively, our findings elucidate a novel mechanism through which KPT-330 destabilizes CRC via translational dysregulation and highlight its potential therapeutic utility in combination regimens for DDLPS.

The eIF4A inhibitor CR-1-31B effectively suppressed tumor growth and induced apoptosis in DDLS, MFS, and UPS patient-derived cell lines and mouse xenografts...Genomic analysis of patient tumors revealed that YAP and WWTR1 were frequently amplified or gained in DDLS, MFS, and UPS and were associated with worse clinical outcomes. Together, our findings identify a new strategy for targeting the Hippo pathway in incurable forms of sarcoma based on inhibition of eIF4A-dependent translation of the key oncogenic transcription factors YAP and TAZ.

The algorithm also performed robustly in the TCGA-SARC data, although with a slightly different optimal cutoff, likely due to differences in gene panels, depth of sequencing, gene coverage, and bioinformatics pipelines. This study presents an effective strategy for screening DDLPS and potentially other MDM2-amplified sarcomas.

Immunohistochemistry plays a crucial role in interpreting a specific diagnosis or narrowing the differential diagnosis of SRCTs. Molecular genetic investigations are essential, particularly in cases exhibiting atypical or overlapping histologic and immunohistological features.

H3K27ac-marked enhancers were enriched near adipocytic marker genes in WDLPS and mesenchymal markers in DDLPS. Together, these findings reveal the cellular heterogeneity of tumor and immune compartments across liposarcoma subtypes and identify regulatory programs driving their differentiation states.

The patient remained recurrence-free at 12-month follow-up. This case emphasizes the critical role of multimodal medical imaging, rigorous histopathological evaluation, and molecular testing in establishing an accurate diagnosis and guiding appropriate management, while highlighting that Madelung's disease may occasionally present with atypical imaging features, such as nodules and septa which closely mimic a malignant lesion.

Our findings highlight peripheral immune profiles as candidate biomarkers for predicting and monitoring ICI efficacy in STS. Incorporating these immune markers could refine patient selection, reduce unnecessary toxicity, and support adaptive treatment strategies for patients with this rare and heterogenous cancer.

This study provides the longest prospective OS data for palbociclib in WD/DD LPS. CDK4/6 inhibition remains a relevant treatment option, especially for patients unsuitable for cytotoxic therapy. CDH18 expression was associated with clinical outcomes and represents an exploratory biomarker signal that warrants independent validation in future prospective, biomarker-focused studies.

It underscores the importance of thorough histopathologic evaluation and immunohistochemical profiling to establish an accurate diagnosis and avoid unnecessary aggressive treatment. Complete surgical excision remains essential for diagnosis and management.
