“…The CCA dismal prognosis, with a 5-years survival rate of 7–20% [ 6 ], is worrisome and, together with the increasing incidence reported for iCCA, explains the endeavor to understand their pathobiology, in order to develop more effective therapeutic strategies. In fact, cisplatin–gemcitabine chemotherapy is often the only possible therapeutic option, while, in the event of failure of the first-line regimen, there is still no clear indication of a second-line regimen to date [ 7 ], although promising results have been observed in randomized controlled trials (RCT), e.g., phase II ABC-06 RCT [ 8 ]. Several authors [ 9 , 10 , 11 ] have underlined the need to overcome this oncology-based approach, and clinical trials have explored the possibility of targeted therapies [ 12 , 13 ], revealing the potential of precision medicine in CCA [ 14 , 15 ], defined as tailoring the treatment to the individual characteristics of each patient.…”
