ROS1 fusion

The combination of osimertinib and crizotinib resulted in a marked clinical and metabolic response, was well tolerated, and the patient remained in remission. This rare case highlights that acquired CD74-ROS1 fusions may contribute to osimertinib resistance and suggests that combination targeted therapy may represent a potential therapeutic approach in selected patients.

Many repotrectinib AEs, including neurological AEs secondary to TRK inhibition, were mitigated with appropriate management, including dose modification and/or pharmacologic intervention.

A novel in-frame gene fusion (TMEM79::NTRK1) was identified in a single tumor sample (0.5%). Our results confirm that LCNECs harbor potentially targetable alterations in KRAS, PIK3CA, RET, BRAF, and NTRK1, albeit at lower frequencies than those typically observed in NSCLC.

The Pan Lung Cancer PCR Panel was highly concordant with other assays. The panel can be performed in local laboratories with a rapid turnaround time and represents an attractive alternative to next-generation sequencing for patients with lung cancer.

The patient received treatment with crizotinib and entrectinib successively. No new severe drug-related adverse events were observed. This case suggests that in patients with ROS1 fusion-positive nonsmall cell lung cancer who have experienced prior ROS1-tyrosine kinase inhibitor treatment failure and concomitant severe renal insufficiency, repotrectinib may represent a potential and tolerable treatment option when fully assessing clinical risks and ensuring close monitoring.

Peripheral monocyte profiling of the patient post-Repotrectinib and localized radiotherapy showed 75% CD8+/CD3 + T cells, 14.2% CD4+/CD3 + T cells, 3.95% regulatory T cells (Tregs), and 38% PD-1 + CD3 + T cells...Furthermore, we also provide a comprehensive review of recent clinical advancements in ALK/ROS1-TKI for NSCLC, including mechanistic insights into TKI resistance development. This case underscores the therapeutic potential of molecular-targeted agents in LUSC and highlights the essential role of NGS-guided precision oncology.
