結膜淋巴瘤之放射治療: 特殊設計之水晶體合金模塊

Purpose: To evaluate and discuss the therapeutic results and technique of conjunctival lymphoma. Materials & Methods: This retrospective study was to review the 10 patients with conjunctival lymphoma treated at National Taiwan University Hosipital from 1988 to 1996. There were 8 men and 2 women. The range of age was 32-75 years old, mean: 59.1 years old. Most of the patients presented with conjunctival mass, reddish eyes and foreign body sensation. The conjunctival lesions in all patients were treated with a single anterior field which covered the entire conjunctiva, using 3 MeV to 10 MeV electron beam. Total dose of 30 Gy to 50 Gy was delivered in 15 to 25 fractions over 23 to 33 days. In all cases, a specially designed lead shield was used to protect the lens. The follow-up time ranged from 24 months to 124 months. follow-up time ranged from 24 months to 124 months. Conclusion: Lymphoma clinically localized to conjunctiva as the initial presentation can be cured by radiation therapy with a dosage of 30 Gy to 40 Gy. The complications of radiation therapy can be minimized with sophisticated treatment technique and well protection of the highly radiosensitive lens
