Despite being the most common intraocular malignancy among adults, choroidal melanoma is a rare cancer type, even more so when accompanied by lung cancer. We report a patient with synchronous choroid melanoma and lung cancer treated with carbon ion radiotherapy (CIRT).
A 41-year-old woman was transferred to our center with a diagnosis of choroidal melanoma in her right eye. During the examination, we found a right lung tumor that was histologically diagnosed as lung cancer. The patient was treated with CIRT for both malignant neoplasms. The CIRT dose was 70 photon equivalent doses (GyE) in five fractions for the right eye choroidal melanoma and 72 GyE in 16 fractions for the right lung cancer. At 3 mo after CIRT, the choroidal melanoma completely disappeared, as did the right lung cancer 7 mo after; the patient was in complete remission.
CIRT may be an effective treatment for double primary lung cancer and choroid melanoma.
Core Tip: Simultaneous choroidal melanoma and lung cancer are extremely rare. This report details a case of a 41-year-old woman with right-side choroidal melanoma and lung cancer treated with carbon ion radiotherapy. Seven months after treatment, the patient was in complete remission.
