Objective:

To analyze the trends in gastric cancer mortality in Peru from 1995 to 2013 and their differences by gender, age groups, geographical and political regions.

Methods:

Ecological study of time series based on 49,690 deaths recorded from the Ministry of Health, from 1995 to 2013. Crude, specific, and standardized mortality rates were calculated by year, according to gender, age group, political and geographic regions. It analyzed trends by estimating joinpoints and annual percentage changes (CPA, for its initials in Spanish), using segmented regression models, adjusted using the software Joinpoint Regression Desktop version 4.5.0.0.

Results:

The standardized mortality rate (SMR) trend due to gastric cancer in Peru was decreasing, falling from 16.1 per 100,000 inhabitants. in 1995 to 11.4 per 100,000 inhabitants in 2013 (CPA: -2.3), observing decreasing trends by age groups, gender, and 17 of 25 political regions. Differences were found when comparing by subgroups: a more accelerated decrease in women (CPA -2.5) versus men (-2.0) and age groups (CPA for 75 - 79 years: -2.57 versus CPA for 40 - 44: -1.39); Three geographic areas with high mortality was identified: Central Andes (Huancavelica, Huánuco, Ayacucho, Pasco, and Junín), northern area (Lambayeque, La Libertad and Cajamarca) and central coast (Ica, Callao, Ancash, and Lima), also trends were observed growing in Huancavelica, Ayacucho and Pasco. On the coast, mortality has decreased since 1998. However, it decreases significantly in the Peruvian Highlands and Jungle as of 2009.

Conclusions:

The trend of SMR due to gastric cancer was decreasing for the period 1995 - 2013 with disparities by sex, age groups, political and geographic regions
