Abstract
Intraocular lymphoma (IOL) is a rare form of non Hodgkin lymphoma (NHL); it has a poor prognosis and is frequently associated with central nervous system (CNS) infiltration. We report the results of a prospective study of 11 patients with IOL who received conventional chemotherapy (CT), followed by salvage high-dose (HD) CT with autologous bone marrow transplantation (ABMT) in five cases. All 11 patients had abnormal funduscopic findings and six had CNS involvement at diagnosis. The diagnosis was based on vitrectomy in 10 cases and cerebral stereotaxic biopsy in one. Pathologic studies showed large-cell NHL in all cases. These large-cell NHL were of the B-cell type in 8 cases and of the T-cell type in two. First-line therapy consisted of a combination of cisplatin 25 mg/m2 as a 24-hour IV infusion on 4 consecutive days, VP-16 40 mg/m2 for 4 days, aracytine 2 g/m2 IV on day 5, and methylprednisolone 500 mg IV daily for 5 days (ESHAP) in 5 cases; alternating courses of ESHAP and HD methotrexate (MTX) in 4 cases; and HD MTX in 2 cases. Three patients underwent ocular and whole-brain radiation therapy. Five refractory patients subsequently received intensive CT with thiotepa 750 mg/m2, busulfan 10 mg/kg and cyclophosphamide 120 mg/kg, followed by ABMT. First-line treatment failed in 10 evaluable cases. One patient died of CNS progression at 12 months. All the patients who underwent intensive CT and ABMT entered CR; two relapsed at 6 months and three are alive in CR 15, 15 and 14 months after ABMT. Six patients are alive with persistent disease at 8, 13, 14, 15, 18 and 24 months. It seems in conclusion that, high-dose thiotepa, busulfan and cyclophosphamide followed by ABMT is effective in some cases of refractory IOL.
