“…Therefore, these two lesions should be included in a single group; that is, high‐grade dysplasia/carcinoma in situ. The dysplasia‐carcinoma sequence is the usual pathway for progression to invasive carcinoma from the extrahepatic bile ducts 47, 48, 49, 50, 51, 52. Non‐invasive papillary carcinomas do not metastasize, and complete excision may be curative, so extensive sampling is recommended to exclude invasion 47…”

“…In 2011, Wakai et al58 reported that after stratification based on pN and pM classification, the ductal resection margin status in patients with extrahepatic cholangiocarcinoma significantly influenced long‐term survival following resection in those with pN0pM0 disease but not in those with pN1 and/or pM1 disease. When the ductal resection margin status is shown to be carcinoma‐positive on examination of frozen sections, additional resection should be considered in patients with localized (pN0pM0) disease 28, 34, 36, 47, 58, 59, 60. In 2017, Tsukahara et al34 first reported that residual carcinoma in situ at the bile duct stumps increased the incidence of local recurrence and adversely affected postoperative survival in patients who underwent resection for early‐stage (pTis‐2N0M0) cholangiocarcinoma.…”

“…There are different histological classifications of ampullary carcinomas (ACs) which [2,3,20] makes comparison of clinical, therapeutic, and prognostic studies of these tumors difficult. So far, two major histological types of these tumors have been recognized: an intestinal type, arising from intestinal mucosa of the papilla, and a biliopancreatic (BP) type, deriving from the BP ductal epithelium.…”

“…Conflicting data have been reported about the frequency of these two histological types due to the absence of reliable and consistent histomorphological criteria for differential diagnosis. [6][7][8][9] MicroRNAs are 19-25-nucleotide-long non-coding RNAs which after cleavage of a precursor into their mature form bind to the RNA-inducedsilencing-complex (RISC) and regulate gene expression posttranscriptionally by a binding of specific mRNA. MicroRNAs regulate many genes known to play important roles in oncogenesis, angiogenesis and tissue differentiation.…”
