ABSTRACT

INTRODUCTION: The association between cancer and stroke is well documented and entails a worse prognosis for both pathologies. However, the prevalence of active and occult cancer among stroke patients is not sufficiently established, and neither are the predictors of cancer-associated stroke. Their knowledge is important for better identification and optimisation of the treatment of these patients. PATIENTS AND METHODS: The aim of this retrospective study is to analyse the characteristics of ischaemic stroke in patients with and without active cancer in a sample of patients admitted to a stroke unit for two years. An overall descriptive and case-control analysis is performed to assess the differences between the two groups. RESULTS: In a sample of 616 patients with ischaemic stroke, a prevalence of cancer was found to be 19.2%, which was active (prior or diagnosed after the stroke) in 7.5% of them. Active cancer was associated with the finding of lesions in several vascular territories, lower haemoglobin and haematocrit values, and higher fibrinogen and C-reactive protein values, a tendency to worse functional status and higher mortality at three months. CONCLUSIONS: A high prevalence of systemic cancer, of any type, as well as active and occult, was found among patients with ischaemic stroke. The presence of ischaemic lesions in several vascular territories and some laboratory markers could be factors to consider in attributing the stroke to cancer or looking for an occult neoplasm in some patients.


TITLE: Ictus asociado a cáncer: estudio de prevalencia y factores predictores entre pacientes con ictus isquémico.Introducción. La asociación entre cáncer e ictus está bien documentada y conlleva un peor pronóstico de ambas patologías. Sin embargo, la prevalencia de cáncer activo y cáncer oculto entre pacientes con ictus no está suficientemente establecida, ni tampoco los factores predictores al ictus asociado al cáncer. Su conocimiento es importante para una mejor identificación y optimización del tratamiento de estos pacientes. Pacientes y métodos. El objetivo de este estudio retrospectivo es analizar las características del ictus isquémico, en pacientes con y sin cáncer activo, en una muestra de pacientes ingresados durante dos años en una unidad de ictus. Se realiza un análisis descriptivo general y de casos y controles, para evaluar las diferencias entre ambos grupos. Resultados. En una muestra de 616 pacientes con ictus isquémico se encontró una prevalencia de cáncer del 19,2%, que era activo (previo o diagnosticado tras el ictus) en un 7,5%. El cáncer activo se asoció con el hallazgo de lesiones en varios territorios vasculares, valores más bajos de hemoglobina y hematocrito, y más altos de fibrinógeno y proteína C reactiva, tendencia a peor situación funcional y mayor mortalidad a los tres meses. Conclusiones. Se encontró una alta prevalencia de cáncer sistémico, de cualquier tipo, y también activo y oculto, entre pacientes con ictus isquémico. La presencia de lesiones isquémicas en varios territorios vasculares y algunos marcadores de laboratorio podrían ser factores que habría que considerar para atribuir el ictus al cáncer o buscar una neoplasia oculta en algunos pacientes.

ABSTRACT

Introducción La esclerosis múltiple (EM) es una enfermedad desmielinizante que causa gran discapacidad en jóvenes. Se han realizado múltiples estudios epidemiológicos en los que se ha constatado una prevalencia variable. El objetivo de este estudio era analizar la prevalencia de esta enfermedad en La Rioja (España) con variables como la edad, el sexo, la forma evolutiva, la clínica de inicio de la enfermedad, la EDSS y el número de brotes, el tratamiento modificador de la enfermedad y los motivos de su retirada, el cáncer y los antecedentes familiares, y la incidencia y la mortalidad. Métodos: Analizar los pacientes diagnosticados de EM según los criterios de McDonald 2005 o Poser, residentes en La Rioja, durante 10 años (2001-2011), recogidos a través del registro hospitalario, la Asociación de Esclerosis Múltiple y los registros personales de los neurólogos. Resultados: En La Rioja, existe una prevalencia de EM de 65 pacientes/100.000 habitantes y una incidencia de 3,5 casos/100.000 habitantes-año. El 67,6% de los pacientes presentan una EM remitente-recurrente. La edad media de inicio es 20-29 años (desde los 12 hasta los 70). La puntuación EDDS es mayoritariamente ≤ 2. Las EM sin tratamiento suponen el 47,6% y el tratamiento más usado son los interferones. Hallamos 4 tumores hematológicos y 7 familias con varios afectados por EM. Conclusiones: La prevalencia y la incidencia son similares a las halladas en el resto de España. La edad media de inicio de la forma primaria progresiva es ligeramente mayor que en otras publicaciones (40-49 años). En familias con varios miembros afectados, la EM podría tener un curso más agresivo. La discapacidad de estos pacientes sigue siendo muy elevada. Son necesarios más estudios epidemiológicos con métodos variables de recogida de datos para afianzar los hallazgos obtenidos en diferentes provincias acerca de la prevalencia


Introduction: Multiple sclerosis is a demyelinating disease that causes severe disability in younger patients. Many epidemiology studies have confirmed a variable prevalence. The objective of this study was to analyse the prevalence of this disease in La Rioja (Spain), using such variables as age and sex; type of progression, initial form of the disease, EDSS and number of relapses; disease-modifying treatment and reasons for treatment withdrawal; personal and family history of cancer; and incidence and mortality. Methods: Analysis of patients in La Rioja diagnosed with MS (according to Poser criteria or the 2005 McDonald criteria) during a 10-year period (2001-2011). Data were collected from hospital records, multiple sclerosis associations, and personal records kept by neurologists. Results: The MS prevalence rate in La Rioja is 65 patients/100 000 inhabitants with an incidence rate of 3.5 cases/100 000 residents per year. Relapsing-remitting MS is present in 67.6% of the patient total. Mean age of onset is 20-29 years (range, 12 to 70). Most EDSS scores were mostly ≤ 2. Untreated MS cases account for 47.6% of the total and the most commonly used therapy is interferon. We detected 4 haematological tumours and 7 families with multiple members affected by MS. Conclusions: Prevalence and incidence are similar to those found in other regions Spain. The average age at onset age for primary progressive MS is slightly higher than in other papers (40-49 years). In families with multiple patients, MS may be more aggressive. Disability in these patients remains very severe. We require more epidemiology studies with a variety of data gathering methods to support findings for prevalence obtained in different provinces
