Larotrectinib was used in 142 patients, demonstrating an 83.80% response rate, with low mortality (2.82%) and recurrence (2.11%) rates. Entrectinib had a lower response rate of 63.64%. We confirm the rarity of NTRK1-3 fusions in sarcomas. TRK inhibitors show high efficacy in sarcomas, emphasizing the necessity of genomic testing in all cases.Protocol registration: https://www.crd.york.ac.uk/PROSPERO/view/CRD42024563594.

This case highlights the essential role of DNA methylation profiling in resolving diagnostic ambiguity and guiding targeted treatment in CNS tumors. It further supports the potential efficacy of entrectinib in NTRK fusion-positive glioneuronal tumors.

Despite the higher grade ≥3 AE incidence, similar rates of dose reduction, interruption, or discontinuation suggest these AEs are manageable. Lorlatinib remains a first-line treatment option for ALK+ metastatic non-small cell lung cancer, offering meaningful benefits to appropriate patients.

Crizotinib showed limited efficacy with a median progression-free survival of 3.5 months. These findings highlight indolent disease behavior but limited TKI benefit, supporting the need for adjuvant trials.

This effort culminated in the identification of compound 8q, which demonstrated potent and selective anti-tumor efficacy against ALK (anaplastic lymphoma kinase) -positive cancer cells (NCI-H2228 and Karpas-299), significantly outperforming ceritinib in enzymatic and cellular assays...The RMSD and RMSF analyses confirmed enhanced conformational stability of the 8q-ALK complex compared to the apo protein. Collectively, these findings highlight 8q as a promising lead compound for the development of novel ALK inhibitors with a favorable efficacy and safety profile.

These findings underscore the importance of routine cardiovascular monitoring, particularly in older patients and those with atrial arrhythmias.

This disruption results in enhanced accumulation of protein aggregates, increased protein polyubiquitination, endoplasmic reticulum stress, and activation of apoptotic pathways. Collectively, our findings support the repurposing of ceritinib in combination with carfilzomib as a translationally relevant and safe strategy to circumvent PI resistance in MM, warranting further clinical investigation in the relapsed/refractory disease setting.

Transition to lorlatinib was associated with extended survival in both groups, reflecting its use as a later-line therapy following resistance. Alectinib demonstrated superior disease control in terms of PFS. Further research is warranted to optimize treatment sequence strategies for ALK inhibitors.

While the presence of bone, liver, and adrenal metastasis were independent risk factors for OS. Alectinib is recommended over crizotinib in the treatment of patients with ALK-positive NSCLC.
