Non-small cell lung cancer with iris metastasis controlled with osimertinib and monthly intravitreal bevacizumab.

PURPOSE

Iris metastases from lung cancer occur rarely. Current treatment options such as surgical iridectomy or radiotherapy are invasive and can potentially lead to negative side effects. Other less invasive alternatives include chemotherapy and intracameral bevacizumab.

OBSERVATIONS

An 81 year-old female with metastatic non-small cell lung adenocarcinoma to the iris in the right eye was treated with daily oral osimertinib 80mg, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), for her systemic lung cancer. In addition, 8 monthly intravitreal bevacizumab (1.25mg/0.05 cc) injections were given. The iris tumor demonstrated complete regression by the third cycle of osimertinib. Following 21 months of osimertinib and 8 bevacizumab injections, the tumor remained regressed. Subsequent iris biopsy confirmed complete tumor regression.

CONCLUSIONS AND IMPORTANCE

In this case, osimertinib and monthly intravitreal bevacizumab controlled iris metastasis due to non-small cell lung cancer. Osimertinib can be beneficial for patients with EGFR-positive lung cancer for both ocular and systemic control.
