No full textThe incidence of thrombotic complications chronologically related to L-asparaginase administration is retrospectively analyzed in 238 adult ALL patients treated according to the GIMEMA protocol ALL 0288. The patients (126 males and 112 females, aged 12-68 years, median 29) received E. coli L-asparaginase (L-ase) in the induction phase at a dosage of 6000 U/m2/day x 7 d starting on d 15, as well as vincristine, prednisone, daunorubicin and cyclophosphamide, the last-named by random 1:1. Ten patients (4.2%) developed thrombotic complications 5-15 d (median 11 d) after the start of L-ase treatment. The thrombotic events, which were lethal in 5 patients, involved the cerebral sinus (5 cases), the cerebral arteria (2 cases), the portal vein (1 case), the pulmonary district (1 case), and a deep vein in the lower extremity (1 case). The occurrence of these complications was not related to the general thrombotic risk factors, nor to the main clinical and laboratory data registered at diagnosis and immediately before the start of L-asparaginase treatment. The present study documents for the first time in a sufficiently large series of adult ALL patients that the incidence and the severity of thrombotic events related to L-ase administration are relevant and need further consideration
Acute megakaryoblastic leukemia: experience of GIMEMA trials
Get PDFThe objective of the study was to evaluate the incidence, characteristics, treatment and outcome of acute megakaryoblastic leukemia (AMeL) in patients enrolled In GIMEMA trials. Between 1982 and 1999, 3603 new consecutive cases of AML aged over 15 years were admitted to GIMEMA trials. Of them, 24 were AMeL. The incidence of AMeL among AML patients enrolled in GIMEMA trials was 0.6% (24/3603). Diagnosis was based on morphological criteria. Out of 11 cytogenetic studies performed two presented chromosome 3 abnormalities. Twelve patients (50%) reached a CR, five (21%) died in induction and seven (27%) were unresponsive. The median duration of was 35 weeks (range 10-441). Seven patients underwent transplantation procedures (1 BMT, 4 aBMT, 2 aPBSCT). Four patients died in CR due to chemotherapy-related complications. Comparing the CR rate between AWL and the other cases of AML enrolled in GIMEMA trials, no differences were observed. These results were mirrored for different age groups. The median survival was 40 weeks. At present, after a followup of a minimum of 2 years, only two patients are alive in CR, all the others having died. A 5-year Kaplan-Meier curve shows a disease-free survival of 17% and an actuarial overall survival of 10%. AMeL is a rare form of AML. The CR duration and the overall survival in this group of patients are very poor, even if similar to those observed in other AML. Furthermore, a high number of deaths in CR were observed. On the basis of these data, a specific therapeutic approach, possibly with innovative treatments, should be evaluated

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
