IntroductionThe immune system plays an essential role in the organism's response to cancer. Several haematological markers can influence prognosis and survival of patients. The objective of this study is to determine their prognostic value in testicular germ cell tumours.Material And MethodsRetrospective cohort study on 164 patients with germ cell tumours. 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 analysed.Results17.7% had NLR>4 and 14.6% ANC>8000/μL. These patients presented higher percentages of residual disease and stage II-III tumours. Patients with elevated absolute neutrophil showed also higher percentages of progression and exitus. 7.3% presented absolute platelet >400000/μL. These patients obtained higher rates of residual disease, nonseminomatous and stage III tumours. 28.4% showed platelet-lymphocyte values>150. This data was associated to higher percentages of residual disease, progression, stage II and III tumours and seminomatous tumours. 83.3% had an lymphocyte-monocyte >3. These patients presented: higher tumour markers in normal range, decreased residual disease rates and higher percentages of stage I and II tumours. The mean survival time was shorter in patients with NLR>4 and absolute neutrophil >8,000/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.ConclusionOur results indicate that the analysed haematological 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 tumours.Copyright © 2019 AEU.
