Marcadores inflamatorios como factor pronóstico en el cáncer de próstata resistente a la castración metastásico / Inflammatory markers as prognostic factors in metastatic castration-resistant prostate cancer

INTRODUCCIÓN: Los marcadores inflamatorios tienen valor pronóstico en diferentes tumores por la intervención de los fenómenos inflamatorios de las diferentes etapas del desarrollo tumoral. El objetivo de este estudio es demostrar el valor pronóstico de estos marcadores, así como de otras variables clínicas y analíticas en pacientes con cáncer de próstata metastásico resistente a la castración (CPRCm). MATERIAL Y MÉTODOS: Estudio de cohortes prospectivo realizado en 80 pacientes diagnosticados de CPRCm. Se recogieron datos clínicos y analíticos, estimándose los siguientes marcadores inflamatorios: recuento total de neutrófilos (RTN), ratio neutrófilo/linfocito (RN/L), recuento total de plaquetas (RTP), ratio plaquetas/linfocito (RP/L), ratio linfocito/monocito (RL/M) e índice sistémico de inflamación (ISI). igualmente se determinaron los valores de albúmina, hemoglobina (Hb), fosfatasa alcalina (FA) y lactato deshidrogenasa (LDH). RESULTADOS: Los pacientes con RTN > 7500, RN/L > 3, RP/L > 150, RL/M > 3 y/o ISI > 535.000, presentaron una mediana de supervivencia significativamente menores que el resto de pacientes, siendo el RTP el único marcador que no mostró asociación significativa. Además, la RN/L, RP/L y el ISI se correlacionaron inversamente con el tiempo de supervivencia. Los pacientes con hipoalbuminemia, anemia y valores elevados de LDH presentaron medianas de supervivencia significativamente menores. La albumina y la hemoglobina presentaron a su vez una correlación directa con el tiempo total de supervivencia. La necesidad de analgesia también se asoció con una menor supervivencia. CONCLUSIÓN: Los valores de determinados marcadores inflamatorios se asocian con menor supervivencia en pacientes con CPRCm, pudiendo considerarse su uso en la práctica clínica para evaluar el pronóstico y estimar la supervivencia

INTRODUCTION: Inflammatory markers have prognostic value in various tumors due to the role of inflammatory phenomena at different stages of tumor development. The aim of this study is to demonstrate the prognostic value of these markers, as well as other clinical and analytical variables in patients with metastatic castration-resistant prostate cancer (mCRPC). MATERIAL AND METHODS: Prospective cohort study carried out on 80 patients diagnosed with mCRPC. Clinical and analytical data were collected, and the following inflammatory markers were estimated: Absolute Neutrophil Count (ANC), Neutrophil-Lymphocyte Ratio (NLR), Total Platelet Count (TPC), Platelet-Lymphocyte Ratio (PLR), Lymphocyte-Monocyte Ratio (LMR) and Systemic Inflammation Index (SII). The values of albumin, hemoglobin (Hb), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were also determined. RESULTS: Patients with ANC> 7500, NLR>3, PLR>150, LMR>3 and/or SII>535,000, presented significantly lower median survival time than the remaining patients, and TPC was the only marker which did not show a significant association. Moreover, NLR, PLR and SII were inversely correlated with survival time. Patients with hypoalbuminemia, anemia, and elevated LDH values had significantly lower median survival time. Albumin and hemoglobin were directly correlated to overall survival time. The need for analgesia was also associated with shorter survival. CONCLUSION: The values of certain inflammatory markers are associated with shorter survival time in patients with mCRPC, and their use in clinical practice can be considered to evaluate the prognosis and estimate survival

Valor pronóstico del recuento de leucocitos y plaquetas, en tumores testiculares de células germinales / Leukocyte and platelet counts as prognostic values of testicular germ cell tumors

Introduction: The immune system plays an essential role in the organism's response to cancer. Several hematological markers can influence prognosis and survival of patients. The objective of this study is to determine their prognostic value in testicular germ cell tumors. Material and methods: Retrospective cohort study on 164 patients with germ cell tumors. Clinical, analytical, histological and evolutionary data were collected. The absolute neutrophil and absolute platelet counts, neutrophil-lymphocyte (NLR), platelet-lymphocyte and lymphocyte-monocyte ratios were estimated at diagnosis. The association that these markers can have with the classic prognostic factors, as well as their effect on prognosis and survival, have been analyzed. Results: 17.7% had NLR > 4 and 14.6% ANC > 8000/μL. These patients presented higher percentages of residual disease and stage II-III tumors. Patients with elevated absolute neutrophil showed also higher percentages of progression and exitus. 7.3% presented absolute platelet > 400,000/μL. These patients obtained higher rates of residual disease, nonseminomatous and stage III tumors. 28.4% showed platelet-lymphocyte values > 150. This data was associated to higher percentages of residual disease, progression, stage II and III tumors and seminomatous tumors. 83.3% had a lymphocyte-monocyte > 3. These patients presented: higher tumor markers in normal range, decreased residual disease rates and higher percentages of stage I and II tumors. The mean survival time was shorter in patients with NLR > 4 and absolute neutrophil > 8000/μL. The ROC curves showed significance in the prediction of progression and values of lymphocyte-monocyte >3, and prediction of survival and values NLR > 4. Conclusion: Our results indicate that the analyzed hematological markers are associated with poor prognoses at diagnosis. Therefore, their use in daily clinical practice can be a valuable tool in the diagnosis and prognosis of patients with testicular germ cell tumors

Introducción: El sistema inmune ejerce un papel clave en la respuesta del organismo frente al cáncer. Existen diversos marcadores hematológicos que pueden influir en el pronóstico y supervivencia de los pacientes. El objetivo de este estudio es determinar su valor pronóstico en tumores testiculares de células germinales. Material y métodos: Estudio de cohortes retrospectivo sobre 164 pacientes con tumores testiculares de células germinales. Se recogieron datos clínicos, analíticos, histológicos y evolutivos. Se estimaron, al diagnóstico, el recuento total de neutrófilos y plaquetas, la ratio neutrófilo-linfocito (RN/L), plaqueta-linfocito(RP/L) y linfocito-monocito (RL/M). Se analizó la relación que estos marcadores pueden tener sobre los factores pronósticos clásicos, así como sobre el pronóstico y supervivencia. Resultados: Un 17,7% tuvieron una RN/L > 4 y un 14,6% un RNT > 8000/μL. Estos enfermos, presentaron mayor porcentaje de enfermedad residual y tumores en estadios II y III. Los enfermos con recuento total de neutrófilos elevado también tuvieron mayor porcentaje de progresión y éxitus. Un 7,3%, tenían un recuento total de plaquetas > 400000/μL. Estos enfermos tuvieron un mayor porcentaje de tumores no seminomatosos, de enfermedad residual y tumores en estadio III. El 28,4% mostraron valores RP/L>150, asociándose este dato a mayor porcentaje de tumores seminomatosos, enfermedad residual, estadios II y III y progresión. El 83,3% tuvieron una RL/M > 3. Estos enfermos presentaron: mayor porcentaje de marcadores tumorales en rango normal, menor porcentaje de enfermedad residual y mayor porcentaje de pacientes en estadio I y II. El tiempo medio de supervivencia fue menor en pacientes con RN/L > 4 y con recuento total de neutrófilos > 8.000/μL. Las curvas ROC mostraron significación en la predicción de progresión y valores de RL/M > 3, y predicción de supervivencia y valores RN/L > 4. Conclusión: Nuestros resultados indican que los marcadores hematológicos analizados se asocian situaciones de mal pronóstico en el momento del diagnóstico. Por tanto, su utilización en la práctica clínica diaria puede ser considerada como una herramienta más en el diagnóstico y pronóstico de pacientes con tumores testiculares de células germinales de testículo
