Alternativas de tratamientos en el cáncer de próstata en Pinar del Río, 2003-2006 / Alternative of treatments in prostate cancer in Pinar del Río, 2003-2006Alternativas de tratamientos en el cáncer de próstata en Pinar del Río, 2003-2006 / Alternative of treatments in prostate cancer in Pinar del Río, 2003-2006Los científicos tienen ideas controvertidas en cuanto a las diferentes formas de tratamiento en el cáncer de próstata y están explorando programas de tratamientos nuevos y formas de combinarlos. Se realizó un estudio observacional, longitudinal, retrospectivo y descriptivo en la Provincia de Pinar del Río, en el  periodo comprendido 1ro. de enero de 2003 al 31 de diciembre de 2006. En la investigación se incluyeron a todos los pacientes que continuaron su seguimiento en consultas de uro-oncología; un total de 265 pacientes para ver la evolución de los mismos a través del antígeno prostático específico. Para precisar el grado de homogeneidad del comportamiento de las variables en una tabla de distribución de frecuencia, se calculó el  intervalo de confianza, encontrando como principales resultados, que existe un número de diagnosticados en el año 2004 y ha existido disminución de los diagnósticos, mientras se ha logrado una mayor asistencia a consultas. Primó el tratamiento bloqueo androgénico total. En  este tipo de tratamiento existe  un  PSA normal en la mayoría de los pacientes a los 6 meses de tratamiento, concluyendo que del total de pacientes que asistieron a consulta y se trataron con bloqueo androgénico total, la mayoría normaliza el PSA a los 6 meses, siendo este más efectivo en el cáncer de la próstata.Palabras Clave: PRÓSTATA, DIAGNÓSTICO, REHABILITACIÓN.ABSTRACTScientists have controversial ideas regarding the different choices of treatment for prostate cancer and are exploring new treatment programs and combining ways. An observation, longitudinal, retrospective and descriptive research was conducted in Pinar del Rio during January 1st, 2003 to December 31st, 2006. All patients following the treatment in the office of urology-oncology were included in the research, the evolution of a total of 265 patients was observed trough the value of Specific Prostatic Antigen. To precise the degree of homogeneity in the behavior of the variables a table to distribute frequency was drawn, calculating confidence interval; main results showed that: a number of patients were diagnosed during 2004, a decrease in diagnosis; however attendance to the offices increased. Total Androgenic Blocking Therapy prevailed. During this type of treatment the SPA presents a normal value; the majority of patients achieve normal SPA at 6 months, being this therapy the most effective in prostate cancer.Key words: PROSTATE, DIAGNOSIS, REHABILITATION.
