BRAF inhibitors (BRAFi) are standard of care for the treatment of BRAF V600 mutation-driven metastatic melanoma, but can lead to paradoxical activation of the mitogen-activated protein kinase (MAPK) signalling pathway. This can result in the promotion of precancerous lesions and secondary neoplasms, mainly (but not exclusively) associated with pre-existing mutations in RAS genes. We previously reported a patient with synchronous BRAF-mutated metastatic melanoma and BRAF wt /KRAS G12D-metastatic colorectal cancer (CRC), whose CRC relapsed and progressed when treated with the BRAF inhibitor dabrafenib (GSK2118436). We used tissue from the resected CRC metastasis to derive a cell line, LM-COL-1..View full abstract
