Abstract
Within 285 adult acute lymphoblastic leukemias (ALL) included in the multicenter GIMEMA 0496 trial and prospectively studied by conventional cytogenetics, 18 cases (6%) with long arm deletion of chromosome 6 (6q) were identified. These cases were divided into: (i) del(6q) only (n = 6); (ii) del(6q) plus other numerical and/or structural abnormalities (n = 8); (iii) del(6q) and other 'specific' translocations (n = 4). The biologic and clinical features of the patients carrying this anomaly, as well as their outcome, were compared with those of 267 patients without del(6q). A T cell phenotype was more frequently associated with del(6q) cases in general (P = 0.001) and particularly with cases presenting del(6q) as the isolated abnormality (P = 0.0027). No significant difference with respect to multidrug resistance (MDR)/P glycoprotein expression was observed between the two groups of patients (21% vs 28% of MDR-positive cases, respectively). A BCR-ABL fusion transcript was less frequently detected in cases with del(6q) (11%) compared with those without the anomaly (29%). p15 and p16 deletions were identified by Southern blot analysis in 21% of cases with del(6q) and in 26% of cases without del(6q). In this latter group, a T cell phenotype was less frequently associated with p15 and/or p16 deletion than in the group carrying del(6q) (36% vs 100% of cases, P = 0.011). Overall, patients with ALL and del(6q) had a high complete remission (CR) rate (83%); however, they had a lower 18 month event-free survival (31% vs 41%) and a higher relapse rate (70% vs 37%, P = 0.02) compared with patients without del(6q). To date, this is the largest series of adult ALL cases reported with del(6q) homogeneously treated, which have also been prospectively studied for MDR expression and for the detection of known fusion genes. This anomaly, as an isolated change, identifies a subset of cases with hyperleukocytosis (median WBC count 52 x 10(9)/l) and a strict correlation with a T cell phenotype. Overall, del(6q) seems to be associated with an unfavorable clinical outcome, although this finding will need to be confirmed by extended FISH analysis.

Abstract
The 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 CR 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 AMeL 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 follow-up 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.

Abstract
BACKGROUND Despite the rational expectation for a survival benefit produced by exercise training among post-myocardial infarction (MI) patients, direct evidence remains elusive. Clinically, changes in autonomic balance toward lower vagal activity have consistently been associated with increased mortality risk; conversely, among both control and post-MI dogs, exercise training improved vagal reflexes and prevented sudden death. Accordingly, we tested the hypothesis that exercise training, if accompanied by a shift toward increased vagal activity of an autonomic marker such as baroreflex sensitivity (BRS), could reduce mortality in post-MI patients. METHODS AND RESULTS Ninety-five consecutive male patients surviving a first uncomplicated MI were randomly assigned to a 4-week endurance training period or to no training. Age (51+/-8 versus 52+/-8 years), site of MI (anterior 41% versus 43%), left ventricular ejection fraction (52+/-13 versus 51+/-14%), and BRS (7.9+/-5.4 versus 7.9+/-3.4 ms/mm Hg) did not differ between the two groups. After 4 weeks, BRS improved by 26% (P=0.04) in trained patients, whereas it did not change in nontrained patients. During a 10-year follow-up, cardiac mortality among the 16 trained patients who had an exercise-induced increase in BRS >or = 3 ms/mm Hg (responders) was strikingly lower compared with that of the trained patients without such a BRS increase (nonresponders) and that of the nontrained patients (0 of 16 versus 18 of 79 [23%], P=0.04). Cardiac mortality was also lower among responders irrespective of training (4% versus 24%, P=0.04). CONCLUSIONS Post-MI exercise training can favorably modify long-term survival, provided that it is associated with a clear shift of the autonomic balance toward an increase in vagal activity.

Abstract
INTRODUCTION One hundred-and-six adult cases of acute lymphoblastic leukemia were prospectively investigated using a highly sensitive interphase fluorescence in situ hybridization assay which utilizes DNA probes that detect a double BCR/ABL fusion signal (D-FISH) in cells carrying the t(9;22) to evaluate the reliability and specificity of this method for the detection of the Ph translocation. The results were compared with those obtained in the same cases by conventional cytogenetics and by reverse-transcription polymerase chain reaction. MATERIALS AND METHODS The study was performed using DNA probes that span the common breakpoints of the t(9;22) translocation and that detect a double BCR/ABL fusion in cells carrying this karyotypic anomaly, one on the abnormal chromosome 9 and one on the Ph chromosome. RESULTS Interphase D-FISH detected a high number of rearranged cases (22/106) compared to conventional cytogenetics (15/106) and RT-PCR (21/106). CONCLUSION Interphase D-FISH emerges as a reliable, fast and relatively inexpensive tool for the detection of BCR/ABL rearrangements in adult ALL patients at diagnosis. It has a sensitivity clearly higher than conventional karyotyping and it may prove also superior to that of RT-PCR in cases with unusual BCR/ABL breakpoints. Our results suggest that D-FISH might be considered as the initial test for the diagnosis of Ph+ adult ALL.

Abstract
Extramedullary (EM) involvement occurs infrequently in acute promyelocytic leukemia (APL) and usually involves skin and CNS. We describe seven patients (four observed at a single institution) who relapsed in various sites of the auditory apparatus, including the external canal and middle ear (temporal bone). Front-line treatment included ATRA and chemotherapy (six patients) or chemotherapy alone (one patient). Three patients had concomitant hematologic relapse, two had molecular relapse and two were in hematologic and molecular remission when ear localization was documented. Local symptoms that stimulated further diagnostic studies included ear bleeding/discharge in the first patient, but were mild in the others (hypoacusia, five patients; earache, two patients). Ear involvement by leukemia was documented by histological and/or molecular studies after local surgery in five cases, and by CT scan or NMR in the remaining patients. We suggest that the ear might represent a specific sanctuary for disease involvement in APL.

Abstract
To date much of the recent work on pathological angiogenesis has focused on inflammatory diseases, diabetes and cancer in particular. Hereditary hemorrhagic telangiectasia or Rendu-Osler-Weber disease provides an example of the genetic disorder of angiogenesis in which a multisystemic angiodysplasia is responsible for severe hemorrhage. The disease pathogenesis is partially explained by a defect in the TGF-beta signaling system, although in more recent works a possible role of other vascular growth factors has been proposed. This paper provides a model of an aberrant angiogenesis in which multiple vascular growth factors could be involved in a diffuse angiodysplasia.

Abstract
In a retrospective analysis of 161 consecutive adult patients with de novo acute myeloid leukemia undergoing induction therapy, including cytarabine, etoposide and anthracyclines, seven patients (4.3%) developed typhlitis. All presented severe neutropenia, fever, abdominal pain and tenderness within 16 days from starting chemotherapy (median 11 days; range 5-16). Three patients underwent surgery and survived, four were treated only with supportive therapy: two recovered and two died. In our experience early recognition of typhlitis and rapid recovery of the neutrophils are the most important determinants of the results of surgical and/or medical approaches. The management of typhlitis, a life-threatening condition, is controversial and depends on many factors characterizing each patient, which must be evaluated in collaboration between the surgeon and the hematologist.

Abstract
BACKGROUND AND OBJECTIVES Fludarabine (FAMP) is the most active single agent in relapsed and refractory patients with B-cell chronic lymphocytic leukemia (B-CLL). However, it is not clear whether it should be used immediatly after failure of chlorambucil (CLB). We addressed such an issue retrospectively analyzing a series of patients in whom FAMP was used as third-line therapy after a sequential use of CLB and CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or CHOP-like regimen, respectively. DESIGN AND METHODS On a retrospective basis, 57 B-CLL patients fulfilling the above mentioned criteria and followed-up in seven different hematologic institutions, were evaluated. RESULTS Of 57 patients who were evaluated for response, 3 (5.2%) achieved a complete response (CR), 30 (52.6%) had a partial response (PR) and the remaining 24 (42.1%) failed to respond to FAMP. Overall median survival from the start of FAMP therapy was 30 months. Survival by tumor response did not show any difference between responders and non-responders (p = 0.536). The survival was significantly shorter in the group of patients with progressive disease than in all other patients included in our study (p = 0.05). Using each patient as his own control (McNemar test) we attempted to evaluate the value of FAMP in inducing a therapeutic response after failure of previous therapies. Among the 37 patients resistant to CLB the response rate was 40.3% with FAMP (p = 0.037) and only 17.5% with CHOP (p = 1.0). Among 35 patients resistant to a CHOP-like regimen, the response rate was 29.8% (p = 0.066) after FAMP therapy. INTERPRETATION AND CONCLUSIONS From our results, it seems that FAMP works better than a CHOP-like regimen in patients resistant to CLB although results do not translate into a survival advantage for responders.

Abstract
PURPOSE Recent reports of extramedullary disease (EMD) at recurrence in acute promyelocytic leukemia (APL) have raised increasing concern about a possible role of retinoic acid (RA) therapy. PATIENTS AND METHODS We analyzed the risk of developing EMD localization at relapse in APL patients enrolled onto two consecutive studies of the Gruppo Italiano Malattie Ematologiche dell'Adulto. The studies investigated chemotherapy alone (LAP0389) versus RA plus chemotherapy (AIDA). RESULTS When all relapse types were taken into account, 94 (51%) of 184 patients and 131 (18%) of 740 patients who attained hematologic remission underwent relapse in the LAP0389 and AIDA studies, respectively (P < .0001). EMD localization was documented in five (5%) of 94 and 16 (12%) of 131 patients (P = .08). Hematologic and/or molecular relapse was diagnosed concomitantly in all but two patients with EMD in the AIDA study. For patients in the LAP0389 and AIDA series, the probability of EMD localization of any type at relapse was 3% and 4.5%, respectively (P = .79), while the probability of CNS involvement was 0.6% and 2% (P = .28). No significant differences were found with regard to mean WBC count and promyelocytic leukemia/retinoic acid receptor-alpha junction type in comparisons of patients with EMD and hematologic relapse. CONCLUSION APL patients receiving all-trans retinoic acid in addition to chemotherapy have no increased risk of developing EMD at relapse as compared with those treated with chemotherapy alone.

Abstract
Retinal abnormalities (RA) are very frequently observed in adult patients with acute myeloid leukemia (AML), but the clinical significance of these findings has not been fully investigated. We examined the fundus oculi in a cohort of 122 adult patients with AML at presentation and analyzed some clinical and biological features to assess whether there was any association with RA. For this purpose, we subdivided the patients into two groups according to the presence or absence of RA (groups 1 and 2, respectively). We considered current laboratory parameters such as white blood cell (WBC) count, hemoglobin (Hb), platelets and serum lactate dehydrogenase (LDH). Moreover, we subdivided the patients into two groups according to age <60 (group A) or > or =60 years (group B) to evaluate a possible association between RA and response to treatment and/or overall survival (OS). In our series, a higher median age and a lower Hb value were associated with group 1 (p = 0.001 and p = 0.04, respectively); the median LDH value was 812 U/l (range 224-5,551) and 607 (range 181-5,244) for groups 1 and 2, respectively (p = 0.02). There was no association between RA and karyotypic alterations. In terms of outcome, in group A (<60 years), 80% patients who achieved complete remission (CR) were in group 2 vs. 13% nonresponders (NR) (p < 0.0001). Median OS of group 2 patients was 49.7 months compared with 7.2 months for those in group 1 (p = 0.002). In group B, 58% patients who achieved CR were in group 1 vs. 15% NR (p < 0.006). Median OS of patients in group 2 was 14.6 months compared with 2.9 months in group 1 (p = 0.02). Our data show that RA are significantly associated with some biological features and with shorter OS in AML patients and this parameter seems to be an effective clinical sign of poor prognosis in terms of CR.

Abstract
We report a case of acute myeloid leukemia (AML-M2) expressing myeloperoxidase (MPO) but no myeloid antigens. A few cases with this discordant phenotype have been reported and an association has been suggested between the lack of CD13 and CD33 in MPO positive AML and the presence of t(8;21). Cytogenetic and molecular analyses performed in our case showed 48,XY,+Y,+8,t(2;9)(q14;p12). We believe that combined approaches can contribute to detect particular AL cases like the present one, that confirms the heterogeneity of AML. However, further studies are needed to clarify the relationship between phenotypic aberrations and cytogenetic abnormalities.

Abstract
We studied the impact of cytogenetics and kind of induction/consolidation therapy on 848 adult acute myeloid leukemia (AML) patients (age 15-83). The patients received three types of induction/consolidation regimen: standard (daunorubicin and cytosine arabinoside (3/7); two cycles); intensive (idarubicin, cytosine arabinoside and etoposide (ICE), plus mitoxantrone and intermediate-dose Ara-C (NOVIA)); and low-dose (low-dose cytosine arabinoside). CR patients under 60 years of age, if an HLA-identical donor was available received allogeneic stem cell transplantation (allo-SCT); otherwise, as part of the program, they underwent autologous (auto)-SCT. CR rates significantly associated with 'favorable' (inv(16), t(8;21)), 'intermediate' ('no abnormality', abn(11q23), +8, del(7q)) and 'unfavorable' (del (5q), -7, abn(3)(q21q26), t(6;9), 'complex' (more than three unrelated cytogenetic abnormalities)) karyotypes (88% vs 65% vs 36%, respectively; P = 0.0001). These trends were confirmed in all age groups. On therapeutic grounds, intensive induction did not determine significant increases of CR rates in any of the considered groups, with respect to standard induction. Low-dose induction was associated with significantly lower CR rates. Considering disease-free survival (DFS), multivariate analysis of the factors examined (including karyotype grouping) showed that only age > 60 years significantly affected outcome. However, in cases where intensive induction was adopted, 'favorable' karyotype was significantly related to longer DFS (P = 0.04). This was mainly due to the favorable outcome of t(8;21) patients treated with intensive induction. Patients receiving allo-SCT had significantly longer DFS (P = 0.005); in particular, allo-SCT significantly improved DFS in the 'favorable' and 'intermediate' groups (P = 0.04 and P = 0.048, respectively). In conclusion our study could provide some guidelines for AML therapy: (1) patients in the 'favorable' karyotype group seem to have a longer DFS when treated with an intensive induction/consolidation regimen, adopted before auto-SCT instead of standard induction; this underlines the importance of reinforcement of chemotherapy, not necessarily based on repeated high-dose AraC cycles. Allo-SCT, independently of induction/consolidation therapy, should be considered an alternative treatment; (2) patients in the 'intermediate' karyotype group should receive allo-SCT; (3) patients in the 'unfavorable' karyotype group should be treated using investigational chemotherapy, considering that even allo-SCT cannot provide a significantly longer DFS, but only a trend to a better prognosis.

BACKGROUND AND OBJECTIVES A pluripotent progenitor cell was demonstrated to be involved in myelodysplastic syndromes (MDS) with normal karyotype or with numerical chromosome aberrations, but the pattern of lineage involvement by the 5q31 deletion in the 5q- syndrome is unknown. We performed this study in order to define the distribution pattern of the 5q- anomaly better in the non-lymphoid cell compartment DESIGN AND METHODS Bone marrow (BM) smears from 8 patients with the 5q- syndrome were studied by a modification of the fluorescent in situ hybridization (FISH) technique that allowed direct visualization of cell morphology. A commercial LSI EGR1 probe (Vysis Inc.) for the 5q31 band was used simultaneously in dual-color experiments with a chromosome-5-centromeric probe (Vysis Inc.) on BM smears from 8 patients with the 5q-syndrome. As additional internal controls a chromosome-7-centromeric probe and a 7q31 probe were used. To establish the sensitivity limit of this approach 5 normal BM smears were studied. All 8 patients had the 5q- chromosome as the sole anomaly in 45% to 75% of the interphase cells. RESULTS For each patient 20-40 erythroblasts were analyzed: they were mostly proerythroblasts and basophilic erythroblasts. In all patients a clone carrying the 5q31 deletion was detected (35-50% of the cells, median 45%). Between 20-50 granulocyte precursors were scored; the 5q31 deletion was found in 40%-50% (median 45%) in all cases. The proportion of neutrophils carrying the 5q deletion was consistently lower than the corresponding value in promyelocytes (28.7% vs 45.6%). In the 20-25 megakaryocytes analyzable in all patients, the overall incidence of 5q31 deletion was 52-68%. Equal proportions of large multilobular megakaryocytes and hypolobular megakaryocytes characteristic of the 5q- syndrome were scored: the latter cells showed the 5q31 deletion more frequently than the former cells (93.6% vs 19.3% of the cells). In 66% to 100% of the cases (median 83%) a few cells with uncondensed nuclear chromatin pattern, and two or three prominent nucleoli with cytoplasmatic hypogranulation were seen in each sample carrying the 5q31 deletion. INTERPRETATION AND CONCLUSIONS We arrived at the following conclusions: i) the transformation in the 5q- syndrome involves an early progenitor cell retaining the ability to proceed along multiple differentiation pathways; ii) there is a preferential distribution of the 5q31 deletion within immature cells and morphologically abnormal megakaryocytes.

Abstract
Some cases of acute myeloid leukemia following organ transplant (PT-AML) have been published in the literature. We report the second case of acute promyelocytic leukemia (APL), which developed post-transplant and immunosuppressive treatment, in a 50-year-old male who had undergone a renal transplant. At diagnosis he presented typical t(15;17)(q12;q13) with additional abnormalities, including +8,t(13;22)(q12;q13) and an abnormal chromosome 1 which was better characterized by fluorescence in situ hybridization (FISH). He obtained cytological, karyotypic and molecular complete remission (CR) with induction treatment according to the all-trans retinoic acid + idarubican (AIDA) protocol; after 12 months, he relapsed (molecular relapse) and achieved molecular remission with all-trans retinoic acid (ATRA) plus mitoxantrone and cytosine arabinoside. After a further 14 months, he was treated with arsenic trioxide for cytological relapse and obtained a third CR; at the cytological relapse the karyotype showed 47,XY,+8, t(15;17)(q22;q21),t(13;22)(q12;q13),der(22)t(1;22)(p22;q13). He is alive 3.3 years after diagnosis of APL. Cyclosporin A (CsA) was given during all cycles of chemotherapy. We did not observe any severe infections or kidney failure during treatments. The use of conventional cytogenetic analysis plus FISH may identify complex karyotype also in transplanted patients receiving immunotherapy, and may also contribute to a better assessment of PT-AL.

Abstract
BACKGROUND AND OBJECTIVES In adult acute myeloid leukemia (AML), a variety of clinical and biological parameters have been examined for their potential value in predicting treatment response. Early response to induction therapy could be an important prognostic factor in this disease. DESIGN AND METHODS We studied the relationship between reduced blasts in bone marrow aspirate on the 14th day (BMA14th) of induction chemotherapy and treatment outcome in 198 adult AML patients of whom 124 were < 60 years old (group A) and 74 > or = 60 years old (group B). Receiver operating characteristic curve analysis was used to assess the prognostic performance of BMA14th. Using the percentages of blasts of < or = 22% and < or = 15% as criteria for predicting treatment outcome gave the highest accuracy in terms of sensitivity and specificity in groups A and B, respectively. RESULTS In group A, of 97 patients with a BMA14th < or = 22%, 77 (79%) achieved complete remission (CR), whereas of 27 patients with a BMA14th > 22%, 22 (81%) were non-responders (NR) (p < 0.0001). The test sensitivity and specificity were 93.9% and 71.4%, respectively. In group B, of 27 patients with a BMA14th < or = 15%, 18 (67%) achieved CR, whereas of 47 patients with a BMA14th >15%, 38 (81%) were NR (p = 0.0001). The test sensitivity and specificity were 66.7% and 80.9%, respectively. INTERPRETATION AND CONCLUSIONS Our data suggest that BMA14th may be a predictive test for CR, helping to identify NR patients early in their disease. Further studies are needed to establish the practical implications of the results of our study.

Abstract
Elderly patients with untreated acute myeloid leukaemia (AML, n = 47) tested the feasibility of out-patient consolidation therapy and post-consolidation treatment (for patients aged < 71 years) with autologous peripheral blood stem cell transplantation (APBSCT). Overall, 13 patients out of 24 (51%) who achieved complete remission (CR) were eligible for further treatment after consolidation. Five patients were primed with granulocyte colony stimulating factor (G-CSF); a suitable number of CD34+ cells were harvested in three patients and were actually autotransplanted. The toxicity of APBSCT was negligible. Psychosocial problems impaired treatment of some patients on an out-patient basis. Resistant disease, toxicity and logistic problems reduced the number of patients to whom this procedure could actually be applied.

Abstract
In cases of keratoconus and consequent penetrating keratoplasty, the refractive requirements of the patient determine the dimensions of the donor button and the receiving wound size. The pre-operative biometric evaluation of the axial parameters may induce the surgeon to choose an oversized button to obtain the right curvature of the cornea and avoid hypermetropia. In this study we present 20 patients transplanted between 1993 and 1995, 13 female, 7 male, aged between 23 and 45 years. These cases demonstrate the utility of this easy and economic technique.

Abstract
A-B scan echography provides accurate information on the location, the nature, the extension of a neoplasm and the involvement of neighbouring tissues as well as on the postsurgical evolution. In this study, we intend to give accurate and useful indications to the surgeon concerning conservative surgery and the follow-up after sclero-uveotumorectomy in cases of uveal neoformations. Between January 1988 and June 1996, we examined 46 patients by means of echography before and after sclero-uveotumorectomy.

Abstract
In our study we have taken into consideration the use of ultrasound biomicroscopy (UBM) in a case of orbital-blepharal lymphoma. The advantages of this methodology, which is considered a refinement of B scan ultrasonography, compared with other instruments at present available on the market, have been described. We have tried to show how the instrument for biomicroscopic ultrasonography makes it possible to obtain images of the anterior segment of the eye in every detail; it is, therefore, capable of giving us information once only available by means of examining histopathological sections. Apart from the advantages, in this work we have also described the limits of this methodology, which in order to allow an accurate diagnosis must always be accompanied by the traditional ocular echography.

Abstract
In this work we underlined the contribution of echography in the parasurgical treatment (photocoagulative) of melanomas of small dimensions. Fourteen patients were examined; some of them were treated with argon laser, others with krypton laser. The echographic examination was performed with the A-B scan technique, naturally accompanied by fluorangiography before and after the operation. An accurate echographic and fluorangiographic follow-up makes it posible to control the evolution of the lesions efficaciously. From this work it is clear how echography gives highly reliable results which allow us, therefore, both to make an adequate therapeutic decision and to evaluate the efficaciousness of the treatment itself.
