Cáncer de próstata localizado. Correlación entre la biopsia por punción y el diagnóstico de prostatectomía radical.
Resumen
Se realiza una revisión de la anatomía patológica de punciones biopsias de próstata y del examen de la pieza postprostatectomía radical. Se analizan y comparan con otras metodologías diagnósticas. Se evalúa el valor diagnóstico de biopsias por punción para predecir la evolución de 31 pacientes de postprostatectomía radical. Se analizan casos de cáncer localizado (74%), no localizado (26%), tumores múltiples (56%) y avanzados (75%). Se compara el valor del antígeno prostático específico (PSA) en dos situaciones: enfermedad circunscripta a la glándula prostática (9,32 ng/ml); enfermedad extraprostática (12 ng/ml). Se evalúan los pesos de las piezas de postprostatectomía radical en cáncer localizado (50 gs) y no localizado (45 gs). Se contrasta el escala de Gleason de la biopsia y de la pieza postquirúrgica. Se analiza la relación entre el volumen tumoral de la biopsia y la pieza operatoria con el estadio del tumor.
