Background. We reviewed the late complications of therapy in 94 patients with localized, primary rhabdomyosarcoma of the orbit treated on the Intergroup Rhabdomyosarcoma Study (IRS)-III protocol (1984-1991). Procedure. A questionnaire was sent to the institutions that had registered 106 patients with orbital RMS on the IRS-III protocol, seeking information about vision, periocular structures, and growth and development of the 102 survivors. Results. Ninety-four questionnaires were returned. The median follow-up interval was 7.6 years. The affected eye was removed from 13 patients because of local recurrence (N = 10) or other causes (N = 3). Seventy-nine of the eighty-one remaining patients had received radiation therapy. Sixty-five of these seventy-nine patients (82%) developed a cataract, and 43 of them (66%) underwent cataract surgery. Fifty-five patients (70%) had decreased visual acuity. Twenty-four patients had a dry eye, and 22 had chronic keratitis, conjunctivitis, or corneal changes. Strabismus, diplopia, retinopathy, and uveitis were uncommon. The orbit was hypoplastic in 48 of 82 patients assessed (59%). Ptosis and enophthalmos were re ported in 22 patients. Decreased statural growth was noted in 13 of the 53 irradiated patients aged 3-14 years at diagnosis with sufficient data (24%). Conclusions. The overall survival rate was 96% (102/106). The eye was preserved in 86% of the patients, but vision was impaired in 70% of them. Other frequent complications were cataract, orbital hypoplasia, keratoconjunctivitis, and ptosis/enophthalmos. The current IRS-V study recommends decreasing the dose of irradiation and using conformal techniques in an attempt to minimize these complications. (C) 2000 Wiley-Liss, Inc.
