Unlike the usual type of all, Ph-positive ALL is associated with a poor prognosis. Nevertheless, in some patients with favorable prognosis features, the disease can be be controlled by intensive chemotherapy. Transplantation of bone marrow from an HLA-matched related donor is superior to other types of transplantation and to intensive chemotherapy alone in prolonging initial complete remissions.

To assess the clinical heterogeneity among patients with acute lymphoblastic leukemia (ALL) and various 11q23 abnormalities, we analyzed data on 497 infants, children and young adults treated between 1983 and 1995 by 11 cooperative groups and single institutions. The substantial sample size allowed separate analyses according to age younger or older than 12 months for the various cytogenetic subsets. Infants with t(4;11) ALL had an especially dismal prognosis when their disease was characterized by a poor early response to prednisone (P = 0.0005 for overall comparison; 5-year event-free survival (EFS), 0 vs 237 712% s.e. for those with good response), or age less than 3 months (P = 0.0003, 5-year EFS, 57 75% vs 23.47 74% for those over 3 months). A poor prednisone response also appeared to confer a worse outcome for older children with t(4;11) ALL. Hematopoietic stem cell transplantation failed to improve outcome in either age group. Among patients with t(11;19) ALL, those with a T-lineage immunophenotype, who were all over 1 year of age, had a better outcome than patients over 1 year of age with B-lineage ALL (overall comparison, P = 0.065; 5-year EFS, 887 713 vs 46714%). In the heterogeneous subgroup with del(11)(q23), National Cancer Institute-Rome risk criteria based on age and leukocyte count had prognostic significance (P = 0.04 for overall comparison; 5-year EFS, 647 78% (high risk) vs 837 76% (standard risk)). This study illustrates the marked clinical heterogeneity among and within subgroups of infants or older children with ALL and specific 11q23 abnormalities, and identifies patients at particularly high risk of failure who may benefit from innovative therapy.

BackgroundThe aim of this study was to describe the patterns of marriage and parenthood in a cohort of childhood cancer survivors included in the Off-Therapy Registry maintained by the Italian Association of Pediatric Hematology and Oncology. Design and MethodsWe analyzed a cohort of 6,044 patients diagnosed with cancer between 1960 and 1998, while aged 0 to 14 years and who were 18 years old or older by December 2003. They were followed up through the regional vital statistics registers until death or the end of follow up (October 30, 2006), whichever occurred first, and their marital status and date of birth of their children were recorded. The cumulative probabilities of being married and having a first child were computed by gender and compared by tumor type within the cohort. Marriage and fertility rates (the latter defined as the number of live births per woman-year) were compared with those of the Italian population of the same age, gender, area of residence and calendar period by means of the observed to expected (O/E) ratios. ResultsDuring the follow-up period, 4,633 (77%) subjects had not married. The marriage O/E ratios were 0.56 (95% CI: 0.51-0.61) and 0.70 (95% CI: 0.65-0.76) among men and women, respectively. Overall, 263 men had 367 liveborn children, and 473 women had 697 liveborn children. The female fertility O/E ratio was 0.57 (95% CI: 0.53-0.62) overall, and 1.08 (95% CI: 0.99-1.17) when analyses were restricted to married/cohabiting women ConclusionsChildhood cancer survivors are less likely to marry and to have children than the general population, confirming the life-long impact of their previous disease on their social behavior and choices. The inclusion of counseling in the strategies of management and long-term surveillance of childhood cancer patients could be beneficial to survivors as they approach adulthood.Key words: childhood cancer, marriage, fertility, long-term survivors, quality of life.Citation: Pivetta E, Maule MM, Pisani P, Zugna D, Haupt R, Jankovic M, Aricò M, Casale F, Clerico A, Cordero di Montezemolo L, Kiren V, Locatelli F, Palumbo G, Pession A, Pillon M, Santoro N, Terenziani M, Valsecchi MG, Dama E, Magnani C, Merletti F and Pastore G,

The first multicentric approach to childhood acute lymphoblastic leukemia (ALL) treatment in Italy started in the early 1970s when the Associazione Italiana di Ematologia ed Oncologia Pediatrica (AIEOP) was founded. Since then the AIEOP has conducted nationwide chemotherapy protocols. Results obtained in three different periods (1982-1986, 1987-1990, 1991-1995) are reported here. Treatment schedules have been characterized by a progressive intensification of systemic therapy and by a progressive substitution of protracted intrathecal therapy for cranial irradiation as central nervous system (CNS) preventive therapy. In the third period cranial radiotherapy (CRT) has been administered only to patients at high risk of relapse or with CNS involvement at diagnosis (about 15% of the overall population). A progressive improvement of therapeutic results, with a steady reduction of isolated CNS relapse rates have been obtained in the three periods considered here. The AIEOP experience shows that CRT can be safely omitted in non-high risk patients, unless they are T-ALL patients with WBC count at the diagnosis у100 000/mm 3 , and that intensification of treatment allows the improvement of overall results with a reduction of the impact of NCI prognostic criteria. Over the years, AIEOP has also continued to foster active cooperation at an international level. In the ongoing AIEOP ALL 2000 study, conducted in cooperation with the BFM group, patients are stratified according to the presence of translocations t(9;22) and t(4;11) and to treatment response (either initial steroid therapy or induction) or minimal residual disease). This cooperation will allow an adequate recruitment of patients to answer relevant randomized questions in the context of a study in which patients are stratified according to minimal residual disease findings.
