|Title||ALK Rearrangement-Positive Pancreatic Cancer with Brain Metastasis Has Remarkable Response to ALK Inhibitors: A Case Report.|
|Abstract Text||Patients with metastatic pancreatic cancer typically have poor prognosis due to the limited effectiveness of existing treatment options. ALK rearrangement-positive is rare in pancreatic cancer, but may occur in those with KRAS-wild type. We present a 34-year-old young man with ALK rearrangement-positive and KRAS-wild pancreatic cancer who had a remarkable response to crizotinib after resistance to prior chemotherapy and re-response to alectinib after brain metastases developed. This clinical observation suggests that comprehensive molecular profiling to guide targeted therapies is not only feasible, but also significantly improves survival outcomes for a subgroup of patients with pancreatic cancer.|

|ATR||E2626*||nonsense||unknown||ATR E2626* results in a premature truncation of the Atr protein at amino acid 2626 of 2644 (UniProt.org). E2626* has been identified in sequencing studies (PMID: 34568053), but has not been biochemically characterized and therefore, its effect on Atr protein function is unknown (PubMed, Sep 2023).|
|CHEK1||S193Y||missense||unknown||CHEK1 S193Y lies within the protein kinase domain of the Chek1 protein (UniProt.org). S193Y has been identified in sequencing studies (PMID: 34568053), but has not been biochemically characterized and therefore, its effect on Chek1 protein function is unknown (PubMed, Oct 2023).|
