Risk factors include age, race, family history, hormone levels, and environment.
Pathogenesis is not precisely known but will have to take into account genetic influences, endogenous hormonal changes, and exposure to environmental substances.,
Prostatic adenocarcinoma is a disease of older men (over 50)
The incidence of latent prostatic adenocarcinoma is believed to be 10% of men in their fifth decade and increases to 60% of men in their ninth decade.
There are racial differences. Compared to the U.S. white population, prostatic carcinoma has a higher incidence in the black population and a lower incidence in the oriental population.
|General Gross Description|
Prostatic adenocarcinomas tend to arise peripherally rather than centrally.
Grossly, carcinomas are better appreciated by palpation than by visualization.
Carcinomas are usually ill defined areas that may be grey/yellow when compared to the native parenchyma.
|General Microscopic Description|
Prostatic adenocarcinomas are histologically diverse and many individual cases will have more than one histologic pattern.
The current favored histologic classification and grading schema is the Gleason system. See references for detailed discussion of the histologic patterns and criteria.
Prostatic adenocarcinomas are reported by adding the combined score of the two dominant histologic patterns, i.e. Gleason grade 3 + 4 = 7.
