Microlitiasis testicular como factor de riesgo de Cáncer testicular - Estudio de casos y controles

Introduction Testicular microliathiasis is an incidental finding with a prevalence that varies between 1,5% and 5,6%. Although a possible association between testicular microlithiasis and testicular cancer has been proposed, this relationship has not been proven. Objective To establish the association between testicular microlithiasis and testis cancer. Methods A case-control study was conducted with the database of a hospital in the city of Bogotà, Colombia, of patients treated between 2007 and 2017. Both cases and controls should be between 5 and 35 years of age, with no other history that would increase the risk of testicular cancer (cryptorchidism, antecedent of contralateral testicular cancer). The cases had to have an ecographic and pathological report of testicular cancer as well as a complete clinical history of assessment by Urology. Likewise, the control group were patients who attended during the same period, with other testicular problems, such as: hydrocele, varicocele or inguinal hernia and with ultrasound findings that ruled out testicular cancer. Results We identified 24 cases and 96 controls. We found a crude OR of 7.86 (95% CI 2.3-26.86) and an OR adjusted for smoking of 10.66 (95% CI 3.29-34, 55). When adjusting for age, family cancer history and varicocele history, no differences were found. Conclusion There is an apparent association between testicular microlithiasis and testicular cancer. Despite this, studies with larger sample sizes would be beneficial. Likewise, since it cannot determine the existence of a temporary association that allows to speak of causality between the two conditions, these results must be taken with caution.
