Case report: Two cases of metastatic pancreatoblastoma in adults: efficacy of Folfirinox and implication of the wnt/β-catenin pathway in genomic analysis
Abstract
Pancreatoblastomas are unfrequent tumors usually found in children. We report two cases of metastatic pancreatoblastomas observed in young women. A systemic chemotherapy (FOLFIRINOX regimen) was associated with a disease control in one case and a partial response in the second with an improvement of general status for both. A high-throughput sequencing of the tumor described in both cases alteration in the Wnt/β-catenin pathway: a mutation in CTNNB1 (exon 3, c.110C>G, p.S37C, reported as a hotspot in COSMIC) in one case and a homozygous loss associated with breakage targeting APC (5q22.2) in the second.
