RESUMEN
Trifluridine/tipiracil is a compound drug, approved in 2015 by the US FDA, and in 2016 by the EMA, for the treatment of chemorefractory metastatic colorectal cancers, after the phase III RECOURSE trial demonstrated significant benefit. Another phase III trial (TAGS) showed significant improvement of overall survival and progression-free survival in refractory gastric cancer and gastroesophageal junction cancer, leading to further approval from the FDA on February 2019, followed by Japan in August 2019 and the EU in September 2019. As promising results have already been observed in the chemorefractory gastric and gastroesophageal-junction cancers, ongoing trials are assessing the use of trifluridine/tipiracil with other standard of care agents, aiming to further improve the survival rate of these patients.

Cholangiocarcinomas (CCAs) comprise of a heterogeneous group of cancers arising in the biliary tract (intrahepatic or iCCA, perihilar or pCCA and distal or dCCA; the latter are known under the collective term of eCCA), each subtype having its own particularities in carcinogenesis, management and prognosis. The increasing incidence in recent decades, limited treatment options and high mortality rates, even in the early stages, have led to an imperious need for more in-depth understanding and development of tailored treatments for this type of aggressive tumour. The wide use of molecular profiling has increased the understanding of biology and identified key molecular drivers, for example, IDH1 mutations or FGFR2 fusions for iCCA, or BRAF mutations in eCCA. Most recently, the FDA approved pemigatinib, an FGFR inhibitor and ivosidenib, an IDH1 inhibitor, but even though progress has been made to better understand the mechanisms of tumorigenesis, genetic make-up, and tumour resistance to standard chemotherapy and targeted therapies, cholangiocarcinomas still represent an important challenge in the daily clinical practice of oncology. The purpose of this review is to highlight the recent progress in the systemic treatment of advanced/metastatic CCAs with a focus on targeted drugs and their biomarkers currently evaluated in early-phase clinical trials.
