Background

Urological cancers comprise approximately one third of all cancers diagnosed in men worldwide, and prostate cancer is the commonest of these. The global burden of prostate cancer rose from 200 000 new cases each year in 1975 to reach an estimated 700 000 new cases in 2002.

In Algeria, in 2002 prostate cancer was the eleventh most common cancer in men with 466 cases 3.3 %. Our study aimed for adjusting prostate cancer incidence trends over the longest period available 1986-2005 in Setif for the effect of age, sex, and period of diagnosis and the geographical distribution. These datas are compared with standardized rates of Cancer Registries in five continents.

Method

Incidence datas were collected in the period 1986-2005 from the population-based cancer registry of Setif, the software used is the Can Reg 4 from the International Agency for Research on Cancer IARC, Lyon. France. Cancer morphology and topography are coded in accordance of the international classification of diseases for oncology manual (ICD-O, the third edition).
