Although primary enucleation continues to be a standard treatment for advanced disease, specific histopathologic high-risk features substantially increase the likelihood of extraocular dissemination. Adjuvant chemotherapy aims to reduce this risk; however, evidence from middle-income countries remains limited. Objective: To determine the prevalence of histopathologic high-risk features in enucleated retinoblastoma and to assess relapse risk and event-free survival (EFS) among patients treated with adjuvant chemotherapy. Methods: We conducted a retrospective analytical study of children with unilateral retinoblastoma treated with primary enucleation and of those with bilateral disease in whom the more affected eye was enucleated before any therapy, between January 2008 and December 2018. Patients presenting high-risk histopathologic features received adjuvant chemotherapy with vincristine, etoposide, and carboplatin (VEC). EFS was estimated using the Kaplan-Meier method and compared using the log-rank test. Results: A total of 101 patients were included; 74 (73%) had unilateral disease. The mean age at diagnosis was 2.1 years. Most eyes demonstrated advanced intraocular involvement (International Classification of Intraocular Retinoblastoma (ICRB) Group E: 82, 81.2%; Group D: 13, 12.9%). Histopathologic high-risk features were common: choroidal invasion occurred in 42 (41.6%) (17, 40.4% massive ≥3 mm), postlaminar optic nerve invasion in 11 (26.2%), and positive optic nerve margin in 16 (38%). Scleral invasion was identified in 20 (21.5%), and anterior chamber invasion in 14 (14%). Thirteen patients (13%) relapsed, all with fatal outcomes. Ten-year EFS was 83.3%. Massive choroidal invasion, scleral invasion, and postlaminar optic nerve invasion were the strongest predictors of poor outcome, and their coexistence was associated with the highest relapse risk. Conclusions: Histopathologic high-risk features are common among children undergoing enucleation for advanced retinoblastoma. Adjuvant chemotherapy is warranted in cases with massive choroidal invasion, scleral infiltration, or postlaminar optic nerve involvement, given their strong association with metastatic relapse.Item ADN del plasma en el cáncer de pulmón(2004) Ferro Mantilla, AnastasiaItem Algunas observaciones sobre el tratamiento esclerosante en las tirosicosis(1941) Rivera, Eduardo J.Item Algunos usos del tubo de miller-Abbott(1943) Albornoz Plata, AlbertoItem ALK- rearranged primary mixed mucinous and non-mucinous lung adenocarcinoma: a case report(Revista Española de Patología, 2025-05-14) Parra-Medina Rafael; Mendivelso-González Daniel Felipe; Castañeda-Motta Catalina; Romero-Rojas Alfredo Ernesto; Carvajal-Fierro Carlos AndrésLung cancer exhibits a diverse array of morphological manifestations and molecular changes, significantly influencing patient diagnosis, prognosis, and treatment strategies. We present the case of a 47-year-old man with a history of smoking, who presented to the emergency room with a 12-month history of haemoptysis. A chest computed tomography (CT) scan revealed a mass in the right upper lobe of the lung and bilateral lung nodules. He underwent a diagnostic wedge resection, which confirmed mixed mucinous and non-mucinous lung adenocarcinoma exhibiting acinar, papillary and micropapillary growth patterns. Molecular studies identified rearrangements in the ALK gene, and staging images revealed central nervous system and bone metastases. This case presents an unusual morphology of mixed mucinous and nonmucinous lung adenocarcinoma and highlights the importance of using immunohistochemical and molecular markers to determine tumour biologyItem Alternativas quirúrgicas en cáncer avanzado de cabeza y cuello(1993) Angel Aristizabal, Javier; De Francisco Zambrano, Juan Hakim Tawil, Antonio; Posso Valencia, Héctor
