Cancer incidence rates are presented for the Nairobi Cancer Registry, a population-based cancer registry (PBCR) covering the population of the capital city of Kenya (3.2 million inhabitants in 2009). Case finding was by active methods, with standard and checks for accuracy and validity. During the period 2004-2008 a total of 8,982 cases were registered comprising 3,889 men (an age standardized incidence rate (ASR) of 161 per 100,000) and 5,093 women (ASR 231 per 1,00,000). Prostate cancer was the most common cancer in men (ASR 40.6 per 100,000) while breast cancer was the most common among women (ASR 51.7 per 100,000). Cervical cancer ranked the second most common cancer among women in Nairobi with an ASR of 46.1 per 100,000, somewhat lower than those of other registries in East Africa region. Breast and cervical cancers accounted for 44% of all cancers in women. Cancer of the oesophagus was common in both sexes, with a slight excess of cases in men (sex ratio 1.3). Unlike other regions in East Africa, the rate of Kaposi sarcoma was relatively low during the period (men 3.6/100,000; women 2.0/100,000). Although incidence rates cannot be calculated for the early years of the registry, the increase in relative frequency of prostate cancer and declines in frequency of Kaposi sarcoma may indicate underlying trends in the risk of these cancers.
