PIK3CA mutation

EBV-GC is characterized by distinct clinicopathological and molecular features. Pathological examination, immunophenotyping, and NGS provide significant value for diagnosis and therapeutic direction.

PIK3CA mutant-mediated cachexia can be overcome by osimertinib (Osi) treatment in Osi-sensitive GEMM. PIK3CA mutant-driven cachexia is mediated through NF-κB activation and can be dampened by combined aspirin treatment. This work provides insights into PIK3CA mutant biological function and mechanisms behind its clinical impacts, and proposes a potential strategy for clinical management.

We present findings that suggest "adolescent" DMGs carry more favorable prognosis and are molecularly distinct from earlier onset pediatric DMGs. These findings have implications in the design and interpretation of clinical trials, in addition to informing clinical practice.

Histopathological evaluation may aid risk stratification alongside KRAS status. Prognostic assessment in clinical settings should take both TNM staging and KRAS status into account.

CRC genetic mutational statuses as well as contributing environmental stress factors such as gut microbiota dysbiosis are prognostically crucial, associated with high risk potential of gene-environment interactions based on machine learning.

Alterations in FGFR3, commonly found in the luminal-papillary molecular subtype associated with low response to immunotherapy, are the target of erdafitinib. Enfortumab vedotin, which targets Nectin-4 (expressed in >95% of urothelial carcinomas), is approved for patients who progress after chemotherapy and/or immunotherapy...Sacituzumab govitecan, an antibody-drug conjugate directed against Trop-2, is effective in basal, luminal and stroma-rich subtypes but not in neuroendocrine carcinomas. In addition, therapies developed for HER2-positive breast cancer have shown efficacy in urothelial carcinoma, with recent data from the DESTINY pan-tumour phase II trial leading to FDA approval of trastuzumab deruxtecan for HER2-overexpressing metastatic urothelial carcinoma. This paper is a comprehensive review of the molecular pathology of bladder cancer, highlighting advances in molecular classification, biomarkers and personalized therapies. The transition from morphology-based classifications to combined morphological and molecular approaches, with therapeutic implications, is also addressed.

This review highlights OCCC molecular underpinnings and therapeutic challenges, emphasizing the need for innovative, multi-targeted strategies. Advances in understanding genetic-immunological interplay in OCCC may enable more effective and durable treatments and improved patient outcomes.

In vitro experiments further demonstrated that ITGB2 knockdown led to inactivation of Akt and ERK signaling and suppression of cell aggressiveness in ER+/HER2- breast cancer cells. ITGB2 gain represents an unfavorable prognostic marker for early recurrence in luminal HER2-negative high proliferative breast cancer, with potential therapeutic implications.

Patients with metastatic HR+HER2- IBC demonstrated a shorter time on treatment suggesting shorter duration of response on CDKI + HT, which is markedly inferior to reported data for non-IBC patients from phase III trials.

We described the genomic landscape of KRASG12D-mutant CRC and PDAC, demonstrating that cases often have additional oncogenic alterations linked to resistance to KRAS inhibition. These alterations are also associated with a worse prognosis. Recognizing these alterations may inform new therapeutic strategies. Further studies are warranted to validate these findings in ongoing clinical trials.

Olaparib and temozolomide (OT) combination therapy is in clinical trial evaluation for rhabdomyosarcoma (RMS). The combination of OT + alpelisib also kills RMS cells which are resistant to standard-of-care combination chemotherapy and was effective in preclinical xenograft mouse models at curbing tumor growth. Our work defines a common resistance pathway in RMS and has credentialled PIK3CA/AKT inhibition as a preclinical strategy to kill therapy resistant RMS.
