Ocular adnexal MALTomas: case series of patients treated with primary radiation.

BACKGROUND: Ocular adnexal mucosal-associated lymphoid tissue lymphomas (MALTomas) are rare, and there are no phase III trials to guide treatment. Primary radiation therapy has been the typical management. This retrospective series reports the experience of a single institution and adds to the current literature. METHODS: Our electronic medical record system and available paper charts were used to identify patients with MALTomas of the lacrimal gland or sac, conjunctiva, and orbital structures, including extraocular muscles. In order to determine pathology, staging, treatment information, local and distant control, salvage treatments, and late toxicity, records were reviewed. RESULTS: Sixteen patients with ocular adnexal MALTomas had local radiation between 1992 and 2011 for primary or recurrent disease. Fifty percent of patients had lymphoma in the conjunctiva, 25% had lymphoma in the lacrimal sac/gland, and 25% of patients had lymphoma in the posterior orbit. Stage IAE disease occurred in 75% of patients, 6% had stage IIAE disease, and 19% of patients had a positive bone marrow biopsy. One patient received chemotherapy as part of initial therapy. The median radiation dose was 30 Gy (25.5-36 Gy) delivered with electrons (31%) or photons (69%). After a mean follow-up of 62.8 months, 2 patients had residual/progressive disease, 2 had contralateral recurrence, and 1 patient had a distant failure, for local control of 87.5% and overall disease control of 68.75%. Recurrence/progression occurred at a median of 35.45 months. Two patients with residual/progressive disease and 1 patient with a contralateral recurrence were followed, successfully salvaged, and have no evidence of disease. Fourteen patients are still alive, and there were no disease-related/toxicity deaths. Seven patients developed cataracts in the treated eye, 2 patients had radiation retinopathy, 2 had permanent dry eye syndrome, and 1 patient had severe keratopathy requiring enucleation. Six patients (3.75%) had worsening visual acuity of unclear etiology. CONCLUSIONS: Primary radiation therapy for ocular adnexal MALTomas with a median dose of 30 Gy led to excellent local control. Patients who did recur were successfully salvaged. Radiation was generally well tolerated, with expected cataractogenesis, given the dose required to achieve local control (with only 1 patient developing severe keratopathy after receiving the highest dose in this series).

State sovereign standing: often overlooked, but not forgotten.

Critics of Virginia's challenge to the constitutionality of the Patient Protection and Affordable Care Act have asserted that Virginia lacked standing to even raise the issue. Such criticism is inconsistent with foundational understandings of the role of states in providing a check on federal power and with the modern standing jurisprudence of the Supreme Court, especially as reflected in the Court's decisions regarding a state's sovereign interest in defending its code of laws. This Article demonstrates that, as a matter of constitutional design and history, as well as under relevant precedents, Virginia clearly had and has standing to bring its challenge.
