Local therapies are increasingly used for ocular preservation in retinoblastoma. In middle-income countries, these techniques pose specific challenges mostly related to more advanced disease at diagnosis. The Grupo de America Latina de Oncología Pediátrica (GALOP) developed a consensus document for the management of conservative therapy for retinoblastoma. Intra-arterial chemotherapy (OAC) is the preferred therapy, except for those with less advanced disease or age younger than 6 months. OAC allowed for a reduction in the use of external beam radiotherapy in our setting. Intravitreal chemotherapy is the preferred treatment for vitreous seeding. Enucleation is the treatment of choice for eyes with advanced disease.

PURPOSE: Waldenstrom Macroglobulinemia (WM) is a rare lymphoma with distinct clinical features, and data from Latin American patients are lacking. Therefore, we aim to investigate the clinical, therapy, and outcome patterns of WM in Latin America. METHODS: We retrospectively analyzed patients with WM diagnosed between 1991 and 2019 from 24 centers in seven Latin American countries. The study outcomes were overall survival (OS) and progression-free survival (PFS). RESULTS: We identified 159 cases (median age 67 years, male 62%). Most patients (95%) were symptomatic at diagnosis. The International Prognostic Scoring System for WM (IPSSWM) at diagnosis was available in 141 (89%) patients (high-risk 40%, intermediate-risk 37%, and low-risk 23%). Twenty-seven (17%) patients were tested for MYD88L265P, with 89% (n = 24 of 27) carrying the mutation. First-line and second-line therapies were adm...
