Purpose
According to the Peruvian public health authorities, cancer is now the second leading cause of mortality in Peru. However, there is still a lack of tangible information that prevents an accurate description of the burden of cancer in the country. Our study is an attempt to fill this research gap and provides figures for cancer incidence and distribution in Peru.
 
Methods
We joined records from both National Institutes for Neoplastic Diseases (INEN) and for Statistics and Informatics (INEI) of Peru. These records included INEN cancer registries between 2007 and 2013 (n=68,168) and demographical data from INEI national censuses over the same period. We estimated the age- and gender-based distributions, as well as regional incidence for each category of cancer registered, as defined by the cancer dictionary of the GLOBOCAN database (C00-097, but C44).
 
Results
Top five most commonly diagnosed cancers were cervix uteri (C53) (16.1%), breast (C50) (12.2%), stomach (C16) (8.9%), leukemia (C91-95) (5.8%), and colorectum (C18-21) (5.4%) cancers. There was a general increasing trend in incidence for all types of cancer, except for Kaposi sarcoma (C46) and cancers of the trachea, bronchus, and lung (C33-34). However, this increase was not equivalent for all types of cancer and varied between regions; some remote regions of Peru being more impacted.
 
Conclusions
The burden of cancer in Peru appears to particularly afflict socially vulnerable populations, such as women and remote, deprived people. There is an urgent need for implementing a national cancer registry to confirm this plight. We are now conducting further geographical correlation studies to identify environmental determining factors for cancer amongst the Peruvian population.
