ABSTRACT
Background: Ependymomas are central nervous system tumors that significantly impact the quality of life and carry a high mortality rate. Both the disease itself and its treatment cause significant morbidity. At a national level in Peru, there are no reports on clinical characteristics of the disease. Methods: This retrospective study captured patient aged less than 19 years with a diagnosis of ependymoma from 2012 to 2022 at a tertiary center in Lima. Results: 85 patients were included with a median follow-up time was 51.6 months. The 5-year overall survival and progression-free survival were 55.89% (95% CI: 44.28 - 65.99) and 37.71% (95% CI: 26,21-49,16) respectively. The main prognostic factors identified were completed treatment (p=0.019), adjuvant chemotherapy (p=0.048), presence of metastasis (p=0.012), and disease recurrence (p=0.02). Conclusions: The survival of patients with ependymoma is below that reported in high-income countries. Incomplete treatment and treatment abandonment are factors that negatively impact the prognosis. Further studies are needed to identify barriers in the referral and treatment process for patients with ependymoma.
ABSTRACT
RESUMEN Introducción. En Perú, el cáncer de mama representa el tipo de cáncer más frecuente en mujeres y el sexto tipo de cáncer más letal en la población general. La sobreexpresión del receptor del factor de crecimiento epidérmico (HER2+) ocurre en 20% a 30% de los cánceres de mama, y se asocia con tumores más agresivos, con mayor recurrencia y mayor mortalidad. Objetivo. Elaborar un conjunto de recomendaciones basadas en evidencias para el diagnóstico y tratamiento del cáncer de mama HER2+, con la finalidad de contribuir a reducir la mortalidad, progresión de la enfermedad y mejorar la calidad de vida. Métodos. Se conformó un panel de especialistas clínicos y metodólogos, quienes identificaron preguntas clínicas relevantes sobre el diagnóstico y tratamiento del cáncer de mama HER2+. Se desarrolló una búsqueda sistemática de GPC en Medline (PubMed), y en organismos elaboradores y recopiladores. Para la formulación de recomendaciones, el panel de especialistas discutió la evidencia y elementos del contexto de implementación de la recomendación, siguiendo la metodología propuesta por el Ministerio de Salud del Perú. Resultados. Se priorizó nueve preguntas clínicas. Se formuló un total de 25 recomendaciones clínicas. Conclusiones. Se elaboró una GPC basada en evidencias, a través de un proceso sistemático, riguroso y transparente desarrollado por un equipo multidisciplinario.
ABSTRACT Introduction. In Peru, breast cancer represents the most common type of cancer in women and the sixth most lethal type of cancer in the general population. Overexpression of the epidermal growth factor receptor (HER2 +) occurs in 20% to 30% of breast cancers, and is associated with more aggressive tumors, with greater recurrence and greater mortality. Objective. Prepare a set of evidence-based recommendations for the diagnosis and treatment of HER2 + breast cancer, in order to help reduce mortality, disease progression and improve quality of life. Methods. A panel of clinical specialists and methodologists was formed, who identified relevant clinical questions about the diagnosis and treatment of HER2 + breast cancer. A systematic search for CPGs was carried out in Medline (PubMed), and in developing and compiling agencies. For the formulation of recommendations, the panel of specialists discussed the evidence and elements of the context of implementation of the recommendation, following the methodology proposed by the Ministry of Health of Peru. Results. Nine clinical questions were prioritized. A total of 25 clinical recommendations were made. Conclusions. An evidence-based CPG was developed through a systematic, rigorous and transparent process developed by a multidisciplinary team.
