NOTCH3 and disease recurrence: The molecular analysis with next-generation sequencing demonstrated that all neoplasms shared the same genomic profile, including NBN and NOTCH3 mutations and chromosomes 1 and 3 alterations.<h4>Conclusions</h4>This case study highlights the essential role of a stringent follow-up after resection of intrahepatic cholangiocarcinoma for detecting early relapsing tumors.
