ABSTRACT
Purpose. Recently neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been reported to be inflammatory parameters that confer poorer outcome in metastatic castration-resistant prostate cancer (mCPRPC). However, these ratios have not been analyzed in patients treated with abiraterone acetate. We explored the relationship between different values of PLR and NLR and survival in mCPRCP treated with abiraterone and their possible relation with a prostate specific antigen (PSA) response. Methods. We retrospectively analyzed 101 patients with mCRPC treated with abiraterone from January of 2012 to November of 2015 in two different hospitals. A cut-off value of 5 for NLR and 150 for PLR were used to compare survival by Kaplan-Meier method. Moreover, an association between these cut-off values and the PSA response was analyzed by a χ2 test. Results. In the case of NLR, the median DFS were 12, 1 months for NLR <5 and 7 months for NLR ≥5, p = 0.061. The median OS were 23.9 months for NLR <5 and 16.3 months for NLR ≥5, p = 0.046. In the case of PLR, the median DFS were 11.8 months for PLR <150 and 10.6 months for PLR ≥150, p = 0.549. The median OS were 27.4 months for PLR <150 and 15.9 months for PLR ≥150, p = 0.005. It was not observed a correlation between the different cut-off values of PLR or NLR and a PSA response ≥25% (p = 0.31). Conclusions. It is shown a better prognostic relationship between PLR and NLR low values and OS that is statistically significant in mCPRC patients treated with abiraterone. Furthermore, it was not shown a relation between PLR and NLR values and PSA response (AU)

Se analiza el papel de la radiocirugía en un caso de meduloblastoma multirrecidivado del adulto tras dos intervenciones, radioterapia fraccionada, quimioterapia y dos autotrasplantes. Se resalta la precocidad de la respuesta clínico-patológica al tratamiento radioquirúrgico (AU)
The role of radiosurgery after multimodality treatment of recurrent desmoplastic adult medulloblastoma is analyzed. The ultra-early clinical and pathological response of this tumor to adjunctive radiosurgery is stressed (AU)

La radio necrosis y el edema cerebral son complicaciones asociadas a la radiocirugía. Presentamos los casos de tres pacientes tratadas con radiocirugía mediante acelerador lineal, de un meningioma de polo frontal izquierdo, peñasco y para sagital parietooccipital, respectivamente, que desarrollaron, entre dos y ocho meses más tarde, lesiones de tipo radio necrótico con extenso edema peritumoral que resultaron resistentes al tratamiento con esteroides y que se han resuelto con la administración de 40 sesiones de oxígeno hiperbárico. Son pocos los casos publicados hasta ahora en la literatura con tan excelentes resultados, por lo que consideramos un hecho a tener muy en cuenta ante las posibles complicaciones de este tipo que puedan presentarse en el transcurso de la práctica radioquirúrgica antes de recurrir a la cirugía (AU)
Radionecrosis with brain edema is a complication of radiosurgery. Three female patients harbouring a frontal pole, petrous and parasagital parietoocipital meningiomas respectively who had been treated with LINAC radiosurgery are presented. Those patients developed, between two and eight months later, a severe symptomatic radionecrosis with a huge brain edema resistant to the usual steroid therapy. Only after 40 sessions of hyperbaric oxygen, a good remission of the lesions was obtained. There are few cases reported in the literature with such a good outcome. Consequentely, this therapy must be taken into account to treat this type of radiosurgical complication before considering surgery (AU)
