2 The overall goal of National Pediatric Cancer Surveillance

The national pediatric cancer surveillance is hospital-based，with pediatric cancer medical institutions as pediatric cancer surveillance sites（hereinafter referred to as the surveillance sites）.The surveillance sites directly report to the NCPCS for two-level case information registration.A national children's cancer surveillance database is gradually established，and a mechanism is improved for information exchange and sharing of the cause of death and cancer，together with other related monitoring systems，thus providing comprehensive，scientific，and accurate data support for national children's cancer prevention and control work（Figure 1-2-1）.
