PurposeThis study reports on the long-term surgical outcomes after the insertion of porous Medpor orbital implants into anophthalmic sockets.MethodsA retrospective chart review of 314 eyes from 314 patients who underwent evisceration, enucleation and secondary procedures using Medpor orbital implants was completed focusing on implant-associated complications and their corrective methods as surgical outcomes.ResultsThe mean follow-up was 50 months (range 6–107 months). The most common complication was blepharoptosis (n=33, 10.5%). Other postoperative complications were exposure (n=14, 4.5%) and implant infection (n=3, 1%). The complications were successfully managed by surgical repair and/or conservative care.ConclusionUsing Medpor resulted in similar surgical outcomes, in terms of the types and frequencies of complications, as other kinds of porous orbital implants.
The American Joint Committee on Cancer has proposed the tumor, node, metastasis (TNM) staging system to overcome the limitations of the Ann Arbor staging system for ocular adnexal lymphoma. We performed this study to evaluate the feasibility of the TNM staging system for ocular adnexal extranodal marginal zone lymphoma of mucosa‐associated lymphoid tissue (OAML). The data form 66 total eyes from 54 patients with biopsy‐confirmed OAML according to World Health Organization classification were retrospectively analyzed. Using the TNM staging system, we reclassified all patients into two categories: (1) T1N0M0 stage group (n = 26), for patients with lymphoma involving only the conjunctiva; and (2) above T1N0M0 or bT1N0M0 stage group (n = 28), for patients with lymphoma extending to the orbit, eyelid, or adjacent structures, and/or bilateral OAML. After a 24‐month median follow‐up period for all patients, the T1N0M0 group revealed higher progression‐free survival (PFS) than the above T1N0M0 or the bT1N0M0 group (P = 0.041). In a separate analysis of only 50 patients categorized as Ann Arbor stage IE, the T1N0M0 group demonstrated higher PFS (100%) than the above T1N0M0 or the bT1N0M0 group (84.7%; P = 0.067). Our data show that the poor prognostic group classified as Ann Arbor stage IE can be further distinguished by using the TNM staging system. Thus, further studies to develop treatment strategies for reducing relapse after treatment for OAML should use the TNM staging system. Am. J. Hematol. 2011. © 2011 Wiley‐Liss, Inc.
BackgroundRadiotherapy is a commonly used treatment for limited-stage ocular adnexal mucosa-associated lymphoid tissue lymphoma (OAML) but showed a substantial relapse risk if the disease involves beyond-conjunctiva or bilateral conjunctivae. Systemic chemoimmunotherapy may be an alternative frontline therapy for the limited disease with those adverse prognostic factors.Patients and methodsWe designed a multicenter, phase II study of the chemoimmunotherapy, rituximab, cyclophosphamide, vincristine, and prednisolone (R-CVP) for the treatment of patients with limited-stage OAML with bilateral or beyond-conjunctival involvement. Thirty-three patients with Ann Arbor stage I OAML with the adverse factors were enrolled. Patients received six cycles of R-CVP followed by two cycles of rituximab therapy.ResultsAt the end of treatment, all the enrolled patients had responded. The cumulative complete response achievement was 93.9% at 2 years. At a median follow-up of 50.6 months, three patients had progressed. Progression-free survival and overall survival at 4 years was 90.3±5.3% and 100%, respectively.ConclusionsThis phase II study demonstrated durable efficacy of R-CVP chemoimmunotherapy, which has promise as an alternative frontline therapy for the limited-stage OAML patients with adverse prognostic factors.Clinical trial registrationNCT01427114.
