What should I do if I develop drug resistance while taking Vemurafenib?

Vemurafenib (Vemurafenib) is a drug that treats melanoma. It inhibits the growth and division of cancer cells by inhibiting the BRAF mutant protein. Some patients develop drug resistance after receiving vemurafenib treatment, which may cause their disease to relapse or progress. Three mechanisms of resistance to vemurafenib (covering 40% of cases) have been discovered, including cancer cells begin to overexpress cell surface proteins PDGFRB and NRAS mutations. Stromal cell secretion of hepatocyte growth factor (HGF).

Some studies suggest that increasing the dose of vemurafenib may help treat resistance. After early effective treatment with vemurafenib/dabrafenib, retreatment with a BRAF inhibitor may be a treatment option for patients with BRAF-mutated metastatic melanoma, but not for all patients. For some locally recurrent melanomas, surgical resection may be an effective treatment. Genetic testing can determine the type of BRAF mutation, which may help select a more appropriate treatment regimen. However, everyone’s physique is different and their resistance to drugs is also different. If drug resistance occurs after using the drug, please inform your doctor in time and do not adjust the drug dosage yourself.
