Post prostatectomy radiotherapy: our experience

Description

Full text: Background: Between 2000 and 2005, at Vidt Medical Center, 85 patients were treated with 3D and IMRT radiotherapy after undergoing radical prostatectomy for localized prostate adenocarcinoma. Objective: To evaluate biochemical recurrence and specific disease free survival and global survival. Materials and method: These patients were divided into two groups: those who engaged in what is called adjuvant therapy (20 patients), who after surgery had increased risk factors and / or persistence of the disease. These risk factors were positive margins, seminal vesicles involvement, capsule infiltration or persistent PSA. The other group were 65 patients referred to as rescue therapy: they were those that presented PSA increase after having undetectable levels as observed nadir after surgery, understanding > 0.2 ng / ml as a high value or palpable nodule on rectal touch with or without positive biopsy. Follow up was between 24 and 84 months, the dose delivered was between 6500 - 7000 cGy. Also evaluated the early and late toxicity, urinary and rectal, according to RTOG criteria. Conclusion: The results obtained confirm the benefits of postoperative radiation therapy for both groups of patients, showing a more favorable trend on those treated with adjuvant therapy. (authors)

Abstract (Spanish)

Antecedentes: entre 2000 y 2005, en Vidt Centro Medico, fueron tratados 85 pacientes con radioterapia 3D e IMRT luego de haber sido sometidos a prostatectomia radical por adenocarcinoma localizado de prostata. Objetivo: evaluar la supervivencia libre de recaida bioquimica, supervivencia libre de enfermedad especifica y supervivencia global. Material y metodo: a estos pacientes se los dividio en dos grupos: aquellos que realizaron lo que se denomino tratamiento adyuvante (20 pacientes), los cuales despues de la cirugia presentaron factores de riesgo aumentado y/o persistencia de la enfermedad. Estos factores de riesgo fueron margenes positivos, vesiculas seminales comprometidas, infiltracion de la capsula o PSA persistente. El otro grupo resultaron 65 pacientes y se los denomino tratamiento de rescate. Fueron aquellos que presentaron elevacion del PSA luego de haberse observado valores indetectables como nadir postcirugia, entediendose como valor elevado > a 0.2 ng/ml o nodulo palpable por tacto digito rectal con o sin biopsia positiva. El seguimiento fue entre 24 y 84 meses, las dosis entregadas fluctuaron ente 6500 y 7000 cGy. Asimismo se evaluo la toxicidad temprana y tardia, urinaria y rectal, de acuerdo con los criterios del RTOG. Conclusion: los resultados obtenidos confirman los beneficios de la radioterapia postoperatoria tanto para pacientes que hicieron tratamiento con criterio adyuvante como para los que lo realizaron como rescate, observandose una tendencia mas favorable en los primeros.
