[The causes of late hospitalization and analysis of mortality in children with malignant neoplasms].

The results of an analysis of histories of 118 pediatric cancer patients and data on 92 autopsied cases are presented. The reasons of late detection of tumors and hospitalization as well as the causes of death were studied. Most of the patients admitted to the hospital (97.5%) had stage III-IV malignancies. The lethality from solid tumors was 2.7 times that from hemoblastoses. Predominant sites of neoplastic growth versus age and a group at risk were identified. Identification of groups at risk, medical check-ups and setting up of specialized oncopediatric departments contribute to early diagnosis of cancer and lowering lethality in pediatric cancer patients.
