[Prognostic factors of prostatic carcinoma].
The histological classification or typing of prostate carcinoma combined with histological grading according to Gleason or WHO with nucleolar subgrading are the most important prognostic factors in carcinoma of the prostate. Prostatic cancer is the most common malignancy in adult males and is the second-most-common cause of cancer death in the USA. The histological Gleason grade may be reduced if only a small amount of tumor tissue is present in the core needle biopsy, in contrast to the combined histological and cytological grading according to WHO with nucleolar subgrading. When there is sufficient carcinomatous tissue in the core needle biopsy, there is no difference from that in radical prostatectomy tissue, because most cases of prostatic carcinoma are highly malignant. DNA cytometry, immunohistochemical analysis with Ki67/Mib1 or molecular pathological studies with the tumor suppressor gene p53 or apoptosis suppressing oncoprotein bcl2 and the density of blood capillaries may be helpful as additional prognostic factors, but only together with the results of the primary histological section. For comparison of grading results with the international literature both grading systems should be used according to Gleason and WHO with nucleolar subgrading.
