Prevalencia de antígeno prostático específico (Psa) en hombres mayores de 45 años de edad de la parroquia San Luis de la ciudad de Riobamba

Abstract

The aim of this study was to determine the prostate-specific antigen in men aged over 45 years in San Luis parish, Riobamba city. The study population consisted of 90 patients, in whom a survey was used to determine age, level of knowledge about prostate cancer, lifestyle and family history. The extraction of blood samples was performed by venipuncture, the samples were transported in a cooler to the Clinical Laboratory of the Sciences College in the ESPOCH, for the determination of PSA the sandwich ELISA technique was used. The tabulation of the data extracted from the surveys allowed correlating the probability of prostate cancer with the risk factors. The results obtained in the determination show that 4% of the study population present altered values of total and free PSA, while 96% of the study population is within the reference values; in addition, the percentage ratio of serum levels of PSA L/T was identified, in which 3. 3% of the population presents a 25% probability of having this pathology and one patient presents a greater probability of having prostate cancer, 28%; it was also determined that the age group that presented altered values is distributed between the ages of 55 to 79 years, being this the most significant range in the determination of PSA in the study population. It is concluded that PSA analysis is a useful tool in the early diagnosis of prostate alterations in men older than 45 years, so it is recommended to conduct training on prostate cancer to encourage total and free PSA testing as a preventive measure.
