Papel del índice neutrófilo/linfocito en pacientes con cáncer de próstata resistente a castración metastásicos tratados en primera línea con abiraterona / Role of the neutrophil/lymphocyte ratio in patients with metastatic castration-resistant prostate cancer treated first-line with abiraterone

INTRODUCCIÓN: En pacientes con cáncer de próstata un NLR elevado parece asociarse a una peor supervivencia. Abiraterona es un tratamiento hormonal de nueva generación que ha aumentado SLP y SG en CPRCm. MATERIAL Y MÉTODOS: Análisis retrospectivo de pacientes tratados con AA en nuestro centro (diciembre del 2012-septiembre del 2018). Analizamos la asociación del NLR (< o ≥ 3) previo y a los 6 meses de tratamiento con la respuesta del PSA, SLP y SG, y hormonosensibilidad previa a AA (< o > 12 meses). RESULTADOS: Hemos tratado a 56 pacientes con una mediana de edad de 82 (62-94), de los cuales 22 pacientes (39%) presentan NLR ≥ 3 previo al tratamiento. Existe una asociación estadísticamente significativa entre el NLR previo al tratamiento < 3 y la respuesta del PSA, OR = 9,444, p =0,001, no existiendo esa asociación con el NLR a los 6 meses de tratamiento. Se encontraron diferencias estadísticamente significativas entre los grupos de NLR < y > 3 previo al tratamiento con abiraterona en SLP con 15 meses de mediana vs.9 y una p = 0,008 y en SG con 20 meses vs.9 con una p = 0,014. Con respecto a la determinación de NLR, a los 6 meses no existen diferencias en las curvas de supervivencia entre ambos grupos. Existen diferencias significativas entre el NLR previo al tratamiento según la duración del tiempo hasta la resistencia a castración (p = 0,026). CONCLUSIONES: Nuestros resultados indican que el NLR podría aportarnos información trascendente y ser constituido un marcador pronóstico temprano y accesible en los pacientes con CPRCm en tratamiento en primera línea con abiraterona

INTRODUCTION: In patients with prostate cancer, high NLR seems to be associated with worse survival. Abiraterone acetate (AA) is a new generation hormonal treatment that has shown to increase PFS and OS in mCRPC. MATERIAL AND METHODS: Retrospective analysis of patients treated with AA in our center (December 2012-September 2018). We analyzed the association of the NLR (< or ≥ 3) before and after 6 months of treatment with PSA response, PFS, OS, and hormone sensitivity prior to AA (< or > 12 months). RESULTS: We have treated 56 patients with a median age of 82 (62-94), of which 22 (39%) had NLR ≥ 3 before treatment. There is a statistically significant association between the NLR prior to treatment < 3 and PSA response, OR = 9,444, P = .001, and there was no association with the NLR at 6 months of treatment. Statistically significant differences were found between the groups of NLR < and > 3 prior to treatment with abiraterone in PFS with 15 months of median vs.9 and P=.008, and in OS with 20 months vs.9 with P = .014. With respect to the determination of NLR at 6 months, there are no differences in the survival curves between both groups. There are significant differences between the NLR prior to treatment according to the length of hormone sensitivity (P = .026). CONCLUSIONS: Our results suggest that NLR could provide relevant information and could act as an early and accessible prognostic marker in patients with mCRPC in first line treatment with Abiraterone

Hyperthyroidism as a clinical manifestation of a embryonal carcinoma of the testis.

This case report describes a case of hyperthyroidism as manifestation of an embryonal carcinoma, and illustrates the causes that led to it. The case describes a 33-year-old male patient who complained of chest pain, palpitations, mild dyspnoea, and weight loss. Blood analysis reveals high levels of human chorionic gonadotropin (833818 mlU/ml), T3 (16.90 pg/ml), and T4 (7.77 ng/dl), as well as a fall of TSH (0.01 ulU/ml). Physical examination and imaging procedures confirm the occurrence of a left testicular tumour associated with numerous lung, hepatic and retroperitoneal metastases. Treatment with carbimazol and propanolol is established to manage hyperthyroidism, and an urgent orchiectomy is performed; the histologic diagnosis confirms an embryonal carcinoma (organoid type), but the patient died unexpectedly 24 hours later after having suffered sudden dyspnoea, tachypnoea, and tachyarrhythmia. Hyperthyroidism is a rare manifestation of a testicular tumour that should be borne in mind with regard to the patient's symptomatology and HCG levels.
