title: [Cancer in children from Morelos state].
abstract: A total of 183 new cases of childhood cancer were registered in the state of Morelos during the period understudy (1996-2007). Taken together, leukemias (45.4%), tumors of the central nervous system (CNST, 13.1%), and lymphomas (10.4%) represented 68.9 % of the total cases. The overall incidence was 141.9 (all rates per 1000 000 children/year), with leukemias having the highest incidence (60.9 per 1,000,000 children/year). By age, children under one year of age had the highest incidence (201.2 per 1 000 000 children/year). The male/female ratio was 1.1. Leukemias and bone tumors showed a tendency to decrease (average annual percent change, AAPC -5.3; CI 95% -8.7, -1.9; and AAP -9.5, CI 95% -17.7, -0.6, respectively. Of the cases of children with solid tumors, 59.4 % was diagnosed in either stage III or IV.
