白内障手術を行った末期癌患者の3症例

Three cases of terminal cancer patients who underwent cataract surgery

要約　目的：末期癌患者に対して白内障手術を行った報告。

症例：［症例1］白内障手術時65歳の男性。Stage Ⅳの肺腺癌化学療法および腰椎転移に対して放射線療法を行っていた。術前矯正視力は右0.7，左0.5。左眼からの手術希望があり，超音波白内障手術を施行した。術後視力は（1.2）に回復し，引き続き右眼の手術も希望していたが，左眼手術6週間後に死亡した。

［症例2］白内障手術時76歳の男性。Stage Ⅳの肺腺癌化学療法中。胸椎転移に対して放射線療法後，脳転移に対してγナイフを施行していた。術前矯正視力は右0.3，左0.2で術後は両（1.2）に改善した。術10か月後に死亡した。

［症例3］白内障手術時80歳の男性。Stage Ⅳの肺腺癌化学療法中。術前矯正視力は両0.9。右眼術後矯正視力は1.2に改善した。右眼手術4か月後に死亡した。

結論：末期癌の患者に対して白内障手術を実施し，生活の質を向上する医療を提供することができた。

Abstract　Purpose：To report three cases of terminal cancer patients who underwent cataract surgery

Case report：［Case 1］A 65-year-old man was diagnosed with lung adenocarcinoma and lumbar vertebrae metastasis. Systemic chemotherapy and lumbar radiation were started. He underwent cataract surgery in the left eye. Preoperative visual acuity was 0.5 in the left eye. The left eye was free of intra or postoperative complications. Best-corrected visual acuity was 1.2 in the left eye postoperatively. He died 6 weeks after the surgery.

［Case 2］A 76-year-old man was diagnosed with lung adenocarcinoma and thoracic vertebrae and brain metastases. Systemic chemotherapy, thoracic vertebrae radiation, and γknife were started. He underwent cataract surgery in both eyes. Preoperative visual acuity was 0.3 in the right eye and 0.2 in the left eye. Both eyes were free of intra or postoperative complications. Best-corrected visual acuity was 1.2 in both eyes postoperatively. He died 10 months after surgery.

［Case 3］An 80-year-old man was diagnosed with left lung adenocarcinoma and right lung metastasis. Systemic chemotherapy was started. He underwent cataract surgery in the right eye. Preoperative visual acuity was 0.5 in the right eye, and it was free of intra or postoperative complications. Best-uncorrected visual acuity was 1.2 in the right eye postoperatively. He died 4 months after surgery.

Conclusion：We report 3 cases of terminal cancer patients who underwent cataract surgery.

In the short term, all 3 cases were free of intra or postoperative complications.

Cataract surgery can improve QOL in terminal cancer patients.
