Question

The following table shows age-specific primary prostate cancer incidence in the combined SEER 18 geographic regions according to selected racial groups, 2005-2009 a. Calculate the age-specific incidence rates (per 100,000) for each racial group. b. Graph these rates for each racial group. Two cities each had a population of 1,000,000. Death from all causes in 'Metro City' was 600 or a rate of 60 per 100,000. In contrast, number of deaths from all causes in 'Suburban City' was 950 or 95 per 100,000. Cancer deaths in both cities were 4 per 100,000 or 40 deaths per city. Risk of a cancer-caused death for both cities was the same. a. What is the proportional mortality ratio (PMR) for each city of all deaths from cancer?

Explanation / Answer

1)

Rate= cases/population

b)

2)Total population= 1,000,000

M city= 600 or 60 per100,000

Urbancity=950 or 95 per100,000

Cancer deaths= 40 or 4 per 100,000

PMR ratio= Number of deaths per cancer /total number of deaths

PMR for Mcity= 40/600 or 4/60 =0.066667

PMR for Urbancity = 40/950 or 4/95 = 0.042105
