Abstract
Introduction: Kidney cancer was considered as the ninth common cancer worldwide. Its
incidence and mortality has been increasing for decades. However, in recent years in many
countries, there is a downward trend.
Objectives: This study sought to evaluate the incidence and mortality rates of renal cancers in
Iran compared to its proportion throughout the world.
Materials and Methods: All mortality and incidence rates of all countries were extracted
from the Global Cancer Project (GLOBOCAN) (data of 2012). The methods of estimation were
quality of the estimation and country-specific that was dependent on the quality and on the
amount of the available data of each country.
Results: The rates have been shown in eight categories; world, very high human development,
high human development, medium human development, low human development, less
developed, more developed regions in addition to Iran. The rates of Iran were close to medium
human developed region rates. In Iran, 1641 kidney cancers cases have been registered which
981 men and 660 women were reported with an overall incidence rate of 1.9 per 100 000 which
is less than world incidence rate for kidney cancers. In Iran, the highest incidence was also
among patients with age of 75 years and more. Additionally, the lowest incidence rates were
among age groups of less than 15 years and age group of 45- 49 years.
Conclusion: Considering the lower incidence and mortality rates of kidney cancer in Iran
compared to other regions of the world, conducting more studies to find related-risk factors to
decline the incidence rates of disease would be necessary.
