[Reporter Wu Liangyi/Taipei Report] Eye tumors can also occur, but they are extremely rare!

49-year-old Ms. Lai began to notice that the lines in her right eye were distorted and deformed 3 years ago, but she seemed to be able to see clearly, so she didn't care. It is a melanoma malignancy with a lower incidence in Asians.

Huang Yixiu, director of the Chang Gung Ophthalmology Department in Linkou, pointed out that melanoma usually grows on the skin, but because the eyes also have melanocytes, melanoma may also grow in or around the eyeball.

The frightening thing about malignant melanoma of the eyeball is that as long as the tumor is more than 0.3 cm thick, it has the ability to metastasize, and there is no way to detect early metastasis.

Huang Yixiu pointed out that any treatment currently used, including enucleation, cannot reduce the mortality of patients.

Fortunately, the incidence rate of intraocular melanoma is extremely low. There are only about 50 to 60 patients per 10 million people in Europe and the United States every year, and intraocular melanoma is even rarer in Asians. According to statistics, the annual incidence rate per 10 million people in Asia is as low as 2 to 6, equivalent to about 5 to 15 newly diagnosed patients in Taiwan every year.

"However, because of the small number of patients, there are not many doctors specializing in this field in Taiwan, and the path for eye tumor patients to see a doctor is particularly difficult." Linkou Changgeng ophthalmologist Zhou Hongda said that most of the initial symptoms of tumors are not obvious, and the only possible symptoms are continuous flashes and flashes. Floaters. Therefore, many times, after several months of examinations, referrals and referrals, when the diagnosis is finally confirmed, the thickness of the tumor has exceeded 1 cm, and the golden opportunity for treatment is missed.

Zhou Hongda explained that in the past, the principle of treatment was often to remove the eyeball when the tumor was seen. The patient has almost no chance of retaining the eyeball and vision, and the appearance may be greatly affected.

Zhou Hongda said that precise proton therapy is known as the golden treatment for ocular melanoma. According to large-scale European and American studies, the use of proton therapy for intraocular melanoma after about 5 to 10 courses of treatment in 1 to 2 weeks, the primary tumor control ratio exceeds 90%, 75% to 93% of the eyeballs are preserved, and as high as 30% to 40% of the patients' vision is preserved.

The eyeball is one of the most delicate organs in the human body and has a low tolerance for radiation side effects.

Zhou Hongda said that precise proton therapy is known as the golden treatment for ocular melanoma. According to large-scale European and American studies, the use of proton therapy for intraocular melanoma after about 5 to 10 courses of treatment in 1 to 2 weeks, the primary tumor control ratio exceeds 90%, 75% to 93% of the eyeballs are preserved, and as high as 30% to 40% of the patients' vision is preserved.

But he also reminded that proton therapy still has its limits. Its ability to control distant tumor metastasis is the same as eyeball removal. About half of the patients will die due to tumor metastasis within 10 years.

Ms. Lai also showed up today to share the treatment process. It has been two years since the treatment, and the tumor has been successfully controlled without removing the eyeballs. The vision distortion has also improved, and it has completely returned to 1.0.

According to the statistics of Chang Gung Hospital, the effectiveness of proton therapy in controlling the primary tumor of the eyeball is analyzed. At present, all patients are under control, and the tumor no longer grows or even shrinks. One of the patients had vision retention of more than 0.5.

The most common side effects after surgery were dry eye (50%), varying degrees of retinal degeneration (40%), and glaucoma (27%).
