“…Histologically, pCCA and dCCA mainly cover mucinous adenocarcinomas or papillary tumors beyond which several additional histological subtypes could be also noticed in eCCA, rarely but factually ( 141 ). Adenosquamous carcinoma featured with concomitant adenocarcinoma and squamous carcinoma accounts for 2% of eCCA as previously reported ( 142 ).…”

“…According to Charbit et al (24), the squamous carcinoma component of tumors, which develops twice as rapidly as does the AC component, is most likely responsible for the cancer's very aggressive biological features (the doubling times are 81 and 166 days, respectively). Some scholars believe that enhanced proliferating cell nuclear antigen action in the squamous component of GBASC might contribute to the higher rate of progression as shown by bigger, locally progressed tumors; this would explain the incidence of bulky tumors and surrounding organ contacts in patients with GBASC and thus make T stage an important prognostic indicator for patients with GBASC (25).…”

“…Given that these cancers comprise less than 1% of all total carcinomas, most of the literature on ASCs is limited to case reports or small series [ 5 , 6 ]. There are no studies that systematically and robustly compare ASCs to nonvariant histologies, which limits the ability of researchers and clinicians to make meaningful comparisons to conventional adenocarcinomas (ACs) and squamous cell carcinomas (SCCs) [ 7 ].…”
