The present study was aimed at assessing differences between the Nordic countries, if any, in late mortality among five-year survivors of childhood cancer. All cases diagnosed before the age of 20 years, between 1960 and 1989, were collected from all Nordic cancer registries. In total, 13,689 patients were identified as five-year survivors and during the extended follow-up 12.3% of them died. Mortality was analysed by decade of diagnosis, for all sites, and for leukaemia, Hodgkin's lymphoma, and central nervous system tumours separately. Analyses were done within a Cox proportional hazards regression framework with adjustments made for gender and age at diagnosis. Hazard ratios were calculated in relation to a weighted Nordic mean based on the proportion of five-year survivors in each country. Overall late mortality was significantly higher in Denmark and Finland than in Norway and Sweden. This could not be explained by inverse differences in five-year survival. The differences diminished over time and had disappeared in the last period. The pattern was similar for both genders. The disappearance of the differences was most probably the effect of a closer collaboration between Nordic paediatric oncologists with development and implementation of common protocols for treatment of childhood cancers in all countries.

Non Hodgkin lymphoma represent about 5% of childhood cancer. They are the third most common group of cancers in children and adolescents, after cerebral tumours and leukemias. They differ from adult lymphomas as they are all high grade tumours, always diffuse and often associated with extra-nodal diseases. Three main histological subtypes predominate: Burkitt, lymphoblastic and anaplastic large cell lymphomas. As the clinical progression is growing fast and treatment different between the 3 subtypes, the diagnosis must be rapidly done and with accuracy.

Improvements in the treatment of the cancers occurring among children and adolescents have resulted in a large number of patients achieving long-term survival. Treatment-related factors have been shown to have an impact on subsequent health status and quality of life, although there are limited data on survivors who are now 2 or more decades past treatment. The Childhood Cancer Survivor Study (CCSS) was established as a resource for investigating the long-term outcomes of a cohort of 5-year survivors of pediatric and adolescent cancer, who were diagnosed between 1970 and 1986. The CCSS consists of more than 14,000 active participants, including survivors of leukemia, brain tumors, Hodgkin's disease, non-Hodgkin's lymphoma, Wilms' tumor, neuroblastoma, soft-tissue sarcoma, and bone tumors, who have provided self-reported sociodemographicand health-related information. The survivor population has been found to be at increased risk of a broad spectrum of adverse outcomes, such as late mortality, second cancers, pulmonary complications, pregnancy loss, giving birth to offspring with low birth weights, and decreased educational attainment. The ongoing evaluation of large and diverse cohorts of cancer survivors, through resources such as the CCSS, will aid in further identifying high-risk individuals who should be the target of innovative intervention strategies.

It has been suggested that breast milk may play a role in the prevention of certain childhood cancers. We undertook a systematic review of published studies investigating the association between breast-feeding and childhood cancers using Medline (1966 to June 2004), supplemented with auto alerts and manual searches. Analyses are based on odds ratios for specific cancers among those ever breast-fed compared with those never breast-fed, pooled using random-effects models. Forty-nine publications were potentially relevant; of these, 26 provided odds ratio estimates for at least one childhood cancer outcome and were included in metaanalyses. Overall, 92% of the studies were case-control studies, 85% relied on long-term recall of feeding history, only 8% examined breast-feeding exclusivity and control response rates were under 80% in over half. Metaanalyses suggested lower risks associated with having been breast-fed of 9% (95% CI = 2-16%) for acute lymphoblastic leukemia, 24% (3-40%) for Hodgkin's disease and 41% (22-56%) for neuroblastoma, with little between-study heterogeneity. The estimates for Hodgkin's disease and neuroblastoma, however, were driven by single studies. There was little evidence that breast-feeding was associated with acute nonlymphoblastic leukemia, non-Hodgkin's lymphoma, central nervous system cancers, malignant germ cell tumors, juvenile bone tumors, or other solid cancers. In conclusion, ever having been breast-fed is inversely associated with acute lymphoblastic leukemia, Hodgkin's disease and neuroblastoma in childhood, but noncausal explanations are possible. Even if causal, the public health importance of these associations may be small. Our estimates suggest that increasing breast-feeding from 50% to 100% would prevent at most 5% of cases of childhood acute leukemia or lymphoma. (c) 2005 Wiley-Liss, Inc.

We determined risk of cancer among first-degree relatives of 5-year survivors of childhood leukemia, lymphoma, central nervous system tumors, sarcomas, Wilms' tumor, and neuroblastoma. Subjects were 13,703 participants in the Childhood Cancer Survivor Study. Family history was collected on 56,759 first-degree relatives using a self-reported questionnaire. Incidence was compared with age- and sex-specific rates using the U.S. Surveillance, Epidemiology and End Results program. Siblings of the survivors had an increased risk of cancer [standardized incidence ratio (SIR), 1.5; 95% confidence interval (95% CI), 1.35-1.7]. Risk was elevated for siblings of probands of leukemia (SIR, 1.3; 95% CI, 1.0-1.6), Hodgkin's disease (SIR, 1.5; 95% CI, 1.2-1.9), non-Hodgkin's lymphoma (SIR, 1.8; 95% CI, 1.3-2.5), Wilms' tumor (SIR, 1.9; 95% CI, 1.2-3.2), soft tissue sarcoma (SIR, 1.5; 95% CI, 1.0-2.2), and bone tumors (SIR, 1.6; 95% CI, 1.2-2.2). Cancer risk was elevated in siblings (SIR, 2.4; 95% CI, 1.5-3.7) and offspring (SIR, 15.0; 95% CI, 5.3-42.9) of probands with second malignant neoplasms (SMN) compared with relatives of probands without SMNs. Siblings of probands with leukemia, Hodgkin's disease, neuroblastoma, and Wilms' tumor had elevated risks for the same malignancies. Parents had no increased risk (fathers' SIR, 0.7; 95% CI, 0.7-0.8; mothers' SIR, 0.9; 95% CI, 0.9-1.0). Seventy percent of siblings' cancers developed in adulthood. These findings suggest that familial cancer syndromes may be revealed as this cohort and family members age and with accrual of more offspring and subjects with SMNs.

During the past 30 years, changes in the treatment of children and adolescents with cancer have led to substantial improvements in survival. Although treatment-related factors have been shown to impact subsequent health status and quality of life, there is limited information on survivors who are now two or more decades after treatment. The Childhood Cancer Survivor Study (CCSS) was established as a resource for investigating the long-term outcomes of a cohort of 5-year survivors of childhood and adolescent cancer, diagnosed between 1970-1986. The CCSS cohort has more than 14,000 active participants, including survivors of leukemia, brain tumors, Hodgkin disease, non-Hodgkin lymphoma, Wilms tumor, neuroblastoma, soft-tissue sarcoma, and bone tumors. Study participants, extensively characterized by their cancer therapy, have provided self-reported sociodemographic- and health-related information. Although the survivor population has been found to be at significantly increased risk of several adverse outcomes, such as late mortality, second cancers, pulmonary complications, pregnancy loss, low birth weight of offspring, and decreased education, the overall proportion of survivors affected is relatively small. Subgroups at high risk of adverse outcomes, defined by treatment-related, demographic, or medical factors, can be identified. The ongoing evaluation of large and diverse cohorts of cancer survivors will aid in further identifying individuals who should be the target of innovative intervention strategies.

To investigate the incidence and outcome of secondary neoplasms in pediatric patients treated for childhood cancer. Between December 1971 and January 2000, a total of 5859 patients younger than age 17 were diagnosed and treated for childhood cancers in our center. Of this group, 1511 (36%) patients were followed for more than 36 months. These long-term survivors were included in this analysis. Twenty-six patients developed a secondary malignancy with an overall risk of 1.7% in this cohort. The male:female ratio was 17:10, with a median age of 7.66 at diagnosis (range, 2 to 16 y). Four patients (14.8%) with Hodgkin lymphoma; 3 each (11.1%) with retinoblastoma and rhabdomyosarcoma; 2 each (7.4%) with Wilms tumor, Ewing sarcoma, medulloblastoma, ganglioneuroblastoma, and non-Hodgkin lymphoma; and 1 each (3.7%) with ependymoma, nasopharyngeal carcinoma, osteosarcoma, astrocytoma had a secondary malignant disease during the long-term follow-up period. Secondary malignant diseases were osteosarcoma in 6 patients, acute lymphoblastic leukemia in 2, acute myelogenous leukemia in 2, and rare malignant disease in others. Four patients with osteosarcoma developed disease within the radiation field. Osteosarcoma was the most frequently occurring secondary neoplasm. Less toxic treatment modalities should be used to decrease the risk of secondary malignant diseases.

This study, originating in the Automated Childhood Cancer Information System (ACCIS), evaluated the time trend in survival after childhood cancer in Europe. The study included more than 72,000 childhood cancer cases aged 0-14 years diagnosed in 1978-1997 and followed-up in 30 population-based cancer registries with a long history of registration and follow-up, in 15 European countries. Survival was analysed using an actuarial life-table method. Five-year cumulative survival probability increased significantly over the study period for all tumour types combined, from 54% for cases diagnosed in the period 1978-1982 to 75% in 1993-1997. Significant improvement was also observed in 10-year survival. Comparing the results for the period 1993-1997 with those for 1978-1982, the largest relative increase in survival was seen for hepatic tumours (32%) and the largest reduction in mortality for non-Hodgkin's lymphomas (60%). Least progress was seen for central nervous system (CNS) tumours. The improvement was statistically significant in all European regions and was most rapid in the East. The ranking among the European regions did not change over the study period, with highest survival in the North and the West and lowest in the East. Extended data collection is necessary to evaluate future time trends and changes in differences between European regions.

Non-Hodgkin's lymphomas (NHLs) constitute a large and heterogeneous group of malignant tumours. This paper describes and interprets geographical patterns (1988-1997) and time trends (1978-1997) of NHL incidence and survival in European children and adolescents. All 7702 lymphomas that were not Hodgkin's, were extracted from the Automated Childhood Cancer Information System (ACCIS) database and included in different analyses. In children under 15 years of age and for the period 1988-1997, the overall NHL age-adjusted incidence rate was 9.4 per million and has been increasing over 20 years by 0.9% per year on average (P=0.002). In adolescents aged 15-19 years, the age-specific incidence rate was 15.9 per million, increasing annually by 1.7% (P=0.007). Five-year survival of children diagnosed in 1988-1997 was 77%, ranging from 58% in the East to 83% in the West. A substantial increase in survival was observed in all European regions. Systematic monitoring and evaluation of childhood and adolescent data on NHL will contribute to further improvement in public health policy for the young population of Europe.

There is now widespread evidence that female survivors of Hodgkin's disease who have been treated with supradiaphragmatic radiotherapy are at an increased risk of breast cancer. Mantle irradiation, which includes irradiation of the mediastinum, conveys a particularly high risk. Previously published studies have found a wide variation in risk. To provide British estimates of risk to inform surveillance programmes, we carried out the first British population-based cohort study of breast cancer in female survivors of childhood Hodgkin's disease. From the underlying cohort of the British Childhood Cancer Survivor Study, a cohort of 18,123 British 5-year survivors of childhood cancer diagnosed between 1940 and 1991, there were in total 383 female 5-year survivors of childhood Hodgkin's disease. Sixteen of these 383 survivors went on to develop invasive breast cancer subsequent to 5-year survival (standardised incidence ratio, 11.5; 95% confidence interval (95% CI), 6.6-18.6) and all of these 16 survivors had been treated with supradiaphragmatic irradiation as treatment for childhood Hodgkin's disease. The cumulative risk of breast cancer by 25 years of follow up was 9.9% (95% CI, 3.3-16.6) for all patients and 12.2% (95% CI, 4.3-20.1) for those treated with supradiaphragmatic radiotherapy. The cumulative risk of breast cancer in female survivors of childhood Hodgkin's disease in Britain is at the lower end of previous estimates. We hope that our data may provide a basis for future surveillance and for counselling survivors as to their likely risk of breast cancer.
