 The CPR of 328 and age-adjusted rate of 192/100000 population in the Parsis is considerably higher than in the developing countries including China, Nigeria and non-Parsi community of India and is even more than developed countries.  Parsis form an ethnic community, distinct from the rest of population in India, therefore this data cannot be extrapolated to determine the estimates in the general population. Age-specific prevalence rates for PD increase with advancing age ,,, and are as high as 247/100000 above age of 60.  In most studies sex-specific prevalence rates were higher in men than in women with the exception of studies from Eastern India which reported that women were more commonly affected than men and this was attributed to longer life expectancy in women. , Incidence and mortality rates of PD are available only from one recent community based study; average age-adjusted incidence rate.
These results are the first ever published incidence rates for Egypt on a national and regional level and clearly demonstrated the seriousness of the cancer problem of Egypt with age-adjusted incidence rates approaching those of the more developed countries. Liver cancer is a serious if not the most serious cancer problem in Egypt. Nonetheless, these rates should be carefully interpreted being based on a short initial phase of registration and a mathematical model that used regional incidence rates.
