Abstract

PURPOSE: The optimal drug regimen and sequence are still unknown for patients with metastatic colorectal cancer (mCRC) who are candidates for third-line (3L) or subsequent treatment. The aim of this study is to know the opinion of experts on the most appropriate treatment options for mCRC in 3L and to clarify certain clinical decisions in Spain. METHODS: Using a modified Delphi method, a group of experts discussed the treatment in 3L of patients with mCRC and developed a questionnaire with 21 items divided into 5 sections. RESULTS: After 2 rounds, the 67 panelists consulted agreed on 17 items (81%). They considered that the main objective of 3L is to equally increase survival and improve patients' quality of life (QoL), but preferably the QoL. It was agreed that patients with mCRC in 3L prefer to receive active versus symptomatic treatment. Panelists considered trifluridine/tipiracil (FTD/TPI) to be the best oral treatment available to them in 3L. In patients with MSI-H or dMMR and BRAF V600E, the panelists mostly prefer targeted treatments. Panelists agreed the use of a therapeutic sequence that not only increases outcomes but also allows patients to be treated later. Finally, it was agreed that FTD/TPI has a mechanism of action that allows it to be used in patients refractory to previous treatment with 5-fluorouracil. CONCLUSION: The experts agreed with most of the proposed items on 3L treatment of mCRC, prioritizing therapeutic options that increase survival and preserve QoL, while facilitating the possibility that patients can continue to be treated later.
