Maternal coffee and alcohol consumption during pregnancy, parental smoking and risk of childhood acute leukaemia.

International audienceINTRODUCTION: We investigated the role of maternal alcohol and coffee drinking and parental smoking on the risk of childhood acute leukemia in a multicenter case-control study. METHODS: The study included 280 incident cases and 288 hospitalized controls, frequency matched with the cases by age, gender and center. Data collection was completed by face-to-face standardized interviews of the case and control mothers. RESULTS: An association with maternal alcohol consumption during pregnancy was observed with acute lymphoid leukemia (ALL) (OR=2.0 [1.4-3.0]) and acute non-lymphoid leukemia (ANLL) (OR=2.6 [1.2-5.8]). Maternal coffee consumption during pregnancy was associated with childhood acute leukemia, ORs increasing in ALL with coffee consumption (OR=1.1 [0.7-1.8], OR=2.4 [1.3-4.7] and OR=3.1 [1.0-9.5], respectively, for 8 cups/day). No association with maternal smoking during pregnancy or parental smoking before or after the index child's birth was observed. DISCUSSION: Our results suggest an association with maternal alcohol and coffee drinking during pregnancy and call for further investigations. Besides, the present study does not support the hypothesis of an increase in the risk of childhood leukemia related to parental smoking

Family history of autoimmune thyroid disease and childhood acute leukemia.

International audienceThe association between a familial history of autoimmune disease and childhood acute leukemia was investigated in a French case-control study that, overall, was designed to assess the role of perinatal, infectious, environmental, and genetic factors in the etiology of childhood acute leukemia. Familial histories of autoimmune disease in first- and second-degree relatives were compared in 279 incident cases, 240 cases of acute lymphocytic leukemia (ALL) and 39 cases of acute non-lymphoblastic leukemia (ANLL), and 285 controls. Recruitment was frequency matched by age, gender, hospital, and ethnic origin. Odds ratios (OR) were estimated using an unconditional regression model taking into account the stratification variables, socioeconomic status, and familial structure. A statistically significant association between a history of autoimmune disease in first- or second-degree relatives and ALL (OR, 1.7; 95% confidence interval (CI), 1.0-2.8) was found. A relationship between thyroid diseases overall and ALL (OR, 2.0; 95% CI, 1.0-3.9) was observed. This association was more pronounced for potentially autoimmune thyroid diseases (Grave's disease and/or hyperthyroidism and Hashimoto's disease and/or hypothyroidism) (OR, 3.5; 95% CI, 1.1-10.7 and OR, 5.6; 95% CI, 1.0-31.1, respectively for ALL and ANLL), whereas it was not statistically significant for the other thyroid diseases (thyroid goiter, thyroid nodule, and unspecified thyroid disorders) (OR, 1.6; 95% CI, 0.7-3.5 and OR, 1.3; 95% CI, 0.2-7.0, respectively, for ALL and ANLL). The results suggest that a familial history of autoimmune thyroid disease may be associated with childhood acute leukemia

Cancer adolescent pathway in France between 1988 and 1997.

International audienceWe report an adolescent cancer pathway from referral, through diagnosis and treatment, to follow-up in France. All cases of cancer among 15-19 years, diagnosed from 1988 to 1997, recorded by nine French population-based cancer registries (10% of French population) were included. The management of adolescent cancer by paediatricians was rare. An adolescents' pathway through cancer care can be summarized as first visit to general practitioner, referral to adult oncologist for haematological malignancy and medical or surgical specialists for solid tumours, treatment in adult unit, and follow-up by adult oncologist, adult medical or surgical specialist, or general practitioner. Only 9% of the 15-19 years are entered into a clinical trial (respectively 6% and 3% into adult and paediatric clinical trial). The inclusion rate changes according to the diagnosis, higher for acute lymphoblastic leukaemia (39%), non-Hodgkin's lymphomas (NHL) (27%), and acute non-lymphoblastic leukaemia (20%). Only 4% of adolescent cancers were managed on shared adult/paediatric departments, especially for soft-tissue sarcomas (14.9%), malignant bone tumours (13.4), central nervous system tumours (6.2%), and NHL (4.4%). Whatever the reasons for lack of participation in clinical trials, an ideal model requiring communication and cooperation between all adult and paediatric specialists involved in adolescent cancer treatment should reduce the large gap in access to cooperative groups

Cancer survival among adolescents in France.

International audienceCancer is the third most significant cause of mortality in French adolescents. The aim of this study was to investigate survival of adolescents with cancer. Overall (OS), disease-specific (DSS) and event-free survival (EFS) were used for the outcome analysis of adolescents (15-19 years) with cancer, recorded by nine French population-based registries during the 1988-1997 period. Five-year OS, DSS and EFS were, respectively, 74.0% (70.7-77.4), 74.5% (71.2-77.9), and 69.0% (65.4-72.5). Five-year DSS was 94% for carcinomas, 89% for germ-cell tumours, 85% for lymphomas, 67% for soft-tissue sarcomas, 64% for CNS tumours, 55% for malignant bone tumours, and 41% for leukaemia. Compared with paediatric series, poor results in acute lymphoblastic leukaemia, malignant bone tumours, and soft-tissue sarcomas have to be highlighted, and deserve further studies concerning the type of regimens used for these patients. Multidisciplinary management of adolescent cancer in paediatric, adult, or specialized units will improve cure rates and treatment outcomes for these patients
