[Geographic occurrence of retinoblastoma]. / O geograficheskom rasprostranenii zabolevaemosti retinoblastomy.

ABSTRACT

The dot mapping technique was used to study the areas of retinoblastoma prevalence in Kazakhstan. A total of 344 retinoblastoma cases were analyzed. The landscape confinement of retinal tumors was taken into consideration. The tumors were more often seen in the children living near water, near the Alatau plain where chemical elements are accumulated, and in large industrial cities polluted by industrial waste products. The data of this study will be used to develop prophylactic measures and for early detection of retinoblastomas in children living in Kazakhstan.
