Purpose : Apoptosis is a process of natural cell death that can occur under both
normal and neoplastic conditions and increased apoptosis in neoplastic conditions is a
feature of the increasing malignant potential. We investigated the possible relationship
between the apoptotic index(AI) and Gleason grade, T stage of prostatic carcinoma.
Materials and Methods : A total of 31 patients with untreated prostatic carcinoma
diagnosed by TURP, transrectal needle biopsy and radical prostatectomy was evaluated.
We used in situ end labeling method for apoptotic staining. AI was compared with
Gleason grade and T stage.
Results : The values of mean AI according to Gleason grade were grade ¥°, 1.3°ú¡¾
0.13, ¥±, 1.38¡¾0.11, ¥², 1.92¡¾0.20, ¥³, 2.0¡¾0.20, ¥´, 2.01 ¡¾0.28. A positive correlation
was noted between apoptotic index and Gleason grade, but not between apoptotic index
and T stage.
Conclusions : We found a positive correlation between AI and Gleason grade and the
possibility that AI may serve as an important morphological marker to predict the
behavior of prostatic carcinoma. (Korean J Urol 1998; 39: 589¡­92)
