Cancer incidence in Oman, 1998-2006

This paper gives a profile of the cancer incidence in Oman for a nine-year period from 1998-2006.

Data from the population-based national cancer registry were consolidated for the said nine-year period and analyzed. A breakdown of the incidence by year and gender have been given. Age-standardized incidence of common cancers in Oman and their age-specific rates have been tabulated. Further, a graphical comparison between common cancers in Omani men and women have been made with those of other Gulf countries and some developed countries.

There were a total of 8,005 (4,224 males and 3,781 females) cases reported and registered in the registry from January 1998 till December 2006 with a male female ratio of 1.1:1. The crude incidence rate was 49.4 per 100,000 males and 45.7 per 100,000 females. The corresponding age-standardized rates were 91.4 and 80.4 per 100,000 in males and females respectively.

Incidence of cancer in Oman is lower than in some Gulf countries and many developed countries. Stomach cancer, non-Hodgkin lymphoma and leukemia are three commonest cancers in males and breast, thyroid and cervical cancers are the most common in females in the nine-year period.
