Pralsetinib was added to osimertinib, resulting in a response lasting 4 months...After one month with alectinib only, osimertinib was added due to the progression, resulting in another response of more than two months. Upon progression with quadruple alterations (EGFR 19del, EGFR C797S, MET amplification, and RET fusions), cabozantinib-gefitinib combination was initiated, leading to rapid deterioration...At the same time, comprehensive genomic testing remains essential for therapeutic decision-making, with ctDNA analysis complementing tissue-based approaches. Notably, the FGFR3-TACC3 fusion may represent a novel resistance mechanism contributing to the limited efficacy of EGFR-TKI.

Small-molecule ALK inhibitors, including crizotinib, have demonstrated high overall response rates (67%-88%) and complete remission rates (~60%-80%) in relapsed or refractory ALK-positive ALCL, often with rapid clinical responses...In addition, it explores emerging strategies for integrating ALK inhibitors into precision-based management of T-cell lymphomas, including combination approaches with chemotherapy, immunotherapy or antibody-drug conjugates. Collectively, these developments highlight a paradigm shift towards biology-driven, personalized therapy in ALK-positive ALCL.

Pan-cancer targeted sequencing provided a comprehensive genomic landscape of UBC, capturing canonical drivers and additional alterations that may be overlooked by bladder-restricted assays. The identification of TP53 and STAG2 as prognostic markers highlights the potential value of broader genomic profiling for biologically informed risk stratification in urothelial bladder cancer.

The combination of tislelizumab and anlotinib demonstrated promising antitumor activity with a manageable safety profile as first-line therapy in patients with advanced PSC.

For NSCLC patients without EGFR or ALK mutations receiving NICT, G-CSF administration could enhance PCR rates. Prospective trials evaluating G-CSF and GM-CSF combined with PD-1 inhibitors are warranted.

This study shows that DMDTCs are characterized by dysregulated phosphorylation signalling, accompanied by chromosomal instability and aberrant methylation, thus underscoring DDR gene-targeted therapy as a promising strategy.

This TPR-ALK fusion-driven IMT demonstrates that disease progression after an initial response to crizotinib can be effectively overcome with lorlatinib, resulting in rapid and durable clinical benefit. These findings add to emerging evidence supporting next-generation ALK inhibitors as effective treatment options for ALK-rearranged IMT after crizotinib failure.
