title: Cancer incidence and survival among infants in Israel, 1998-2007.
abstract: Cancer during the first year of life is relatively rare and often has clinical and biological properties different from those of the same histologic type of cancer occurring in older children. The aim of this study was to find differences in epidemiology and survival between infants and older children and to compare the percentage of distribution of infant cancer types in Israel with that reported in the United States. We collected infant <1 year of age cases diagnosed between 1998 and 2007 as having cancer from the database of the Israel National Cancer Registry, a total of 309 cases with an incidence rate of 228.5 cases per million. The largest group was diagnosed with neuroblastoma (35%) with an incident rate of 80 per million, followed by leukemia (15.9%), with acute lymphoid leukemia and acute myeloid leukemia accounting for most of this group and central nervous system malignancies comprised 10.7% of infant cancer. One hundred and fifty four new cases of infant girls was diagnosed compared to 155 infant boys with an incidence rates of 234 cases per million for girls and 224.7 for boys, not statistically significant (F:M rate ratio of 1.04). The 5-year survival rates seen in the different groups were leukemia: 55.3%, lymphoma: 71%, CNS tumors: 53.3%, neuroblastoma: 93.4%, retinoblastoma: 94.7% renal tumors: 90.9%, hepatic tumors: 63.3%, soft tissue sarcoma: 76.2%, germ cell neoplasms: 83.3%, and other epithelial neoplasms: 100%. Our study did not find survival differences with statistical significance upon comparing survival rates between different genders and ethnic groups.
