Because these disorders may be limited to the skin or be a manifestation of a systemic histiocytic neoplasm, correlation with clinical features is essential. Molecular genetic analysis to identify mutations in the mitogen-activated protein kinase pathway should be considered to provide options for targeted therapy.

After failure of gemcitabine/docetaxel chemotherapy, next-generation sequencing identified an IGFBP5-ALK fusion (breakpoint: IGFBP5 exon 1 - ALK exon 19), a TERT promoter mutation, and a homozygous CDKN2A/CDKN2B/MTAP deletion. This case highlights the first documented response to an ALK inhibitor in ALK-rearranged HG-ESS. The findings underscore the importance of comprehensive molecular profiling in identifying targetable alterations in rare sarcomas and support the use of iruplinalkib as an effective therapeutic option in this setting.

This case supports considering IMT in pediatric pelvic masses and reinforces that complete surgical resection remains the primary treatment. Although ALK gene rearrangement was not associated with therapeutic intervention in the present case, its identification remains diagnostically relevant and may provide important insights into management decisions in selected clinical scenarios, such as recurrence or unresectable disease.

Limited CIR beyond 12 months existed for brigatinib and ensartinib. Results from the Asian group's CIR aligned with global trials. Due to lower BM CIR, lorlatinib showed higher BM management cost savings compared to crizotinib and alectinib in Chinese 1 L patients.

Conditioning was based on total body irradiation (TBI) in 30 patients and on chemotherapy in 27 patients, mainly with reduced-toxicity conditioning (RTC; Treosulfan, Fludarabine, and Thiotepa). Our data support the use of TBI-free conditioning and suggest improved outcomes with unrelated donors receiving ATLG prophylaxis. NCT00317408.

Several clinical factors associated with survival were identified. Larger studies are needed to investigate how treatment sequences may be optimized to further improve survival outcomes.

These discrepancies likely reflect biases in model training data and the probabilistic nature of generative language models. Despite this quantified generative bias, the utility of these cohorts for non-epidemiological tasks like educational simulation is discussed, provided methodological transparency is maintained.

The patient was treated with a modified MARIETTA protocol (without rituximab) and consolidated with a carmustine-based autologous stem cell transplant. shows complete metabolic response on PET-CT and MRI brain. This case presents the first successful treatment of a synchronous presentation of CNS and systemic ALK-positive ALCL, and the importance of a multidisciplinary approach for diagnosis.
