Abstract

Vemurafenib, a specific inhibitor of mutated BRAF kinase, may activate wild-type BRAF and therefore induce squamous cell skin carcinomas in patients treated for melanoma. All vemurafenib clinical trials excluded patients with multiple primary malignant tumors; therefore, the action of this drug on concurrent BRAF wild-type malignancies remains insufficiently studied. We observed a patient, who was administered vemurafenib for BRAF mutation-containing melanoma, but experienced immediate relapse of previously controlled breast cancer disease. Interestingly, breast cancer lesions underwent regression soon after vemurafenib discontinuation. Therefore, caution must be taken while considering vemurafenib treatment for patients with multiple tumors.

Keynote webinar | Spotlight on antibody–drug conjugates in cancer

Antibody–drug conjugates (ADCs) are novel agents that have shown promise across multiple tumor types. Explore the current landscape of ADCs in breast and lung cancer with our experts, and gain insights into the mechanism of action, key clinical trials data, existing challenges, and future directions.
