The study of incidence patterns and survival rates in childhood malignancies is important in assisting the planning of treatment centers and in gaining clues about the etiology. Because there were only few reports about childhood cancer survival in our country, we reported the results of 7-years follow-up of childhood cancer in our center. An analysis of the patterns and survival rates of 320 children, who have been diagnosed between January 1990 and December 1997 were evaluated. The median age was 6 years (M/F=1.4). One hundred twenty-one (37.9%) of these patients suffered from lymphoma, 42 (13.1%) had renal tumors, 34 (10.6%) had neuroblastoma, 33 (10.3%) had tumors of the central nervous system (CNS), 26 (8.1%) had bone tumors, 18 (5.6%) had soft tissue tumors, 11 (3.4%) had retinoblastoma, 10 (3.1%) had germ cell tumors and 25 (7.9%) had other tumors, respectively. Ninety-six children (30%) have been lost to follow up. Five-year overall survival (OS) for all patients was 64%, however, the 5-year OS rates for lymphomas and solid tumors were 71% and 60%, respectively. We conclude that lymphomas were the most common tumor type in our center, being similar to other cancer reports from Turkey and some developing countries. Although our results revealed comparatively high rates for Wilms' tumor and neuroblastoma, a deficit of cases was seen for CNS tumors.
