Abstract:
The discovery of BRAF mutation in ~50% of melanomas led to the development of small molecule BRAF inhibitors, including sorafenib, debrafenib, and vemurafenib. Clinical trials have shown these agents to be effective in treatment of metastatic and locally advanced melanoma, increasing overall and progression-free survival. However, some of the most common toxicities associated with BRAF inhibitor therapy include adverse skin events such as rashes, photosensitivity, hyperkeratosis, papillomas, keratoacanthomas, and squamous cell carcinomas. Here, the authors describe 3 patients who developed keratinocytic neoplasms on the eyelid, including invasive squamous carcinoma secondary to vemurafenib. Vigilant screening and a high index of suspicion for eyelid carcinomas are recommended in patients treated with vemurafenib.
Insights
BRAF inhibitors effectively treat melanoma but can cause skin issues. This study highlights eyelid keratinocytic neoplasms, including squamous cell carcinoma, as a rare but serious side effect of vemurafenib therapy.
Area of Science:
- Oncology
- Dermatology
- Pharmacology
Background:
- BRAF mutations are common in melanoma, leading to targeted therapies like BRAF inhibitors.
- BRAF inhibitors (e.g., vemurafenib) improve survival in advanced melanoma.
- Common side effects include various skin toxicities.
Observation:
- Three patients developed eyelid keratinocytic neoplasms.
- One patient developed invasive squamous cell carcinoma.
- These neoplasms were associated with vemurafenib treatment.
Findings:
- Vemurafenib therapy can lead to the development of eyelid keratinocytic neoplasms.
- Invasive squamous cell carcinoma is a potential complication.
Implications:
- Clinicians should maintain a high index of suspicion for eyelid carcinomas in patients on vemurafenib.
- Vigilant screening for skin neoplasms is crucial during BRAF inhibitor therapy.
- Early detection and management of these neoplasms are essential.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
