Choroidal Metastasis of Non-Small Cell Lung Cancer That Responded to Gefitinib

Abstract EN

A 52-year-old Japanese woman presented with optical symptoms, including left-sided myodesopsia, blurred vision, narrowed visual field, and diminished visual acuity.

Ocular evaluation revealed a metastatic tumor in the choroid.

Further examinations identified pulmonary adenocarcinoma as the primary tumor.

Because an epidermal growth factor receptor gene (EGFR) mutation was detected in a biopsy specimen, gefitinib treatment was initiated.

Dramatic responses were obtained in the primary tumor and metastatic foci.

Optical symptoms improved and remained stable for 5 months during the treatment, until relapse.

This report demonstrates that gefitinib is effective for choroidal metastasis of pulmonary adenocarcinoma harboring an EGFR mutation.
