Lack of Response to Vismodegib in a Patient with Advanced Basal Cell Carcinoma: A Case Report
Purpose: Basal cell carcinoma (BCC), the most common type of skin cancer in humans, rarely progresses to locally advanced or metastatic BCC. The size, extent, and location of the lesion should be carefully considered when selecting a treatment option for patients with BCC.
Methods: Moreover, clinicians should review the potential for significant deformity and anticipated morbidity, when considering radiation therapy and surgery for treatment. Vismodegib, the first approved oral therapy for advanced BCC, is a treatment option that clinicians might consider for patients with BCC lesions that exhibit the clinical characteristics as described above.
Results: In this manuscript, we reviewed the mechanism of action, clinical efficacy, and safety of vismodegib and consider the possible causes for a lack of response to the drug.
Conclusion: The therapeutic response to these tumors may be limited by the challenge of acquired resistance against smoothened antagonists.
