Abstract
Hydatid localization in the major branches of the pulmonary circulation have rarely been reported. The AA. describe the case of a young male patient, previously operated for pulmonary and hepatic hydatidosis, who was unresponsive to medical treatment and died of right heart failure. At necropsy a large hydatid cyst occluding the right proximal branch of the artery was found.

Abstract
The efficacy of autologous bone marrow transplantation in leukemia and lymphoma may depend upon the selective elimination of malignant cells from human bone marrow in vivo and in vitro. A cyclophosphamide derivative (ASTA-Z 7654) and etoposide (VP16-213) have been tested on lymphoma and leukemia cell lines in a model that may represent a bone marrow situation in complete remission. The influence of different concentrations of normal mononuclear cells and tumor cells in this model and the activity of the two chemotherapeutic agents in the presence of bone marrow cells or peripheral blood cells were evaluated. A major inhibitory effect was observed using the two agents in combination; low doses of ASTA-Z and VP16 consecutively added to the mixture of malignant cells and normal mononuclear cells resulted in a greater elimination of tumor line cells than with ASTA-Z alone at the current 100 micrograms/ml dose. In contrast, no major toxicity on normal human bone marrow precursors was observed; the effect of treatment on hemopoietic recovery with the two agents either alone or in combination was evaluated on CFU-GM growth after long-term bone marrow cultures. Despite a profound growth inhibition at day 0, a recovery was observed in all cases after 7 or 14 days. The use of multiple chemotherapeutic agents in the treatment of bone marrow in vitro could decrease the possibility of malignant cells surviving while sparing normal bone marrow precursors.

Abstract
Three of 37 adolescents in long-term remission from childhood acute lymphoblastic leukemia (ALL) developed malignant multifocal gliomas several years after completing treatment that included central nervous system (CNS) prophylaxis with radiation (RT) and intrathecal methotrexate (IT-MTX). No recurrence of the leukemia was evident when the CNS tumors were discovered. Seventeen other similar cases have been recorded. The occurrence of second malignancies is reviewed in the context of this development and of the oncogenic effects of radiation. It is probable that prolonged exposure to IT-MTX may have had a synergistic effect with radiation in contributing to the unusual incidence of glial tumors in these patients.

Abstract
Two AML patients, whose leukemic clonogenic cells totally reacted to the anti-lactofucopentaose III S4-7 monoclonal antibody (MoAb), underwent autologous bone marrow transplantation, in first complete remission, after in-vitro purging with S4-7 MoAb and complement. After ablative chemotherapy (BAVC regimen) and reinfusion of S4-7 purged cells, regeneration of marrow cells occurred with prompt recovery of granulopoiesis and erythropoiesis. A more delayed platelet recovery was observed. The two patients are in complete remission at 20 and 11 months from ABMT. The results indicate that immunologic purging with S4-7 MoAb is safe and suitable for selected AML patients undergoing ABMT.

Abstract
Between 1980 and 1985, 175 patients with acute leukaemia in first or subsequent complete remission (CR) were treated by chemotherapy or chemoradiotherapy followed by transfusion of autologous bone marrow cells that had been collected days or months previously. In 85 cases, autologous marrow cells were treated ex vivo with cytotoxic drugs or monoclonal antibodies with the intention of removing residual leukaemic cells. The actuarial relapse-free rate was 52% at 2 years. Of 89 patients autografted for acute non-lymphocytic (myeloid) leukaemia (ANLL), 60 were treated in first remission and 18 in second CR; their relapse-free rates at 2 years were 67% and 41% respectively (P less than 0.001). In contrast, of 77 patients autografted for acute lymphoblastic leukaemia (ALL), 32 were treated in first CR and 28 in second CR and their actuarial relapse free rates at 2 years were 56% and 55% respectively (P = NS). There was no significant difference in leukaemia relapse rates between patients autografted with purged and those autografted with non-purged marrow cells. These preliminary results suggest that autologous bone marrow transplantation may be valuable if offered to patients with ANLL in first CR or to patients with ALL in first or second CR but the need for marrow purging remains uncertain.

Abstract
Thirteen patients with AML in first relapse were treated with high dose combination chemotherapy followed by cryopreserved autologous bone marrow transplantation (ABMT). The first four patients received the COATA-Roma regimen, consisting of CTX, VCR, CA, 6-TG and ADM; nine additional patients received the BAVC regimen consisting of BCNU, AMSA, VP-16 and CA. A median of 1.6 X 10(8) fractionated nucleated bone marrow cells/kg body weight were reinfused. The median of GM-CFU-C recovered was 4.7 X 10(4)/kg. Out of 13 patients, 10 (76.9%) achieved CR, 3 had profound aplasia and died from hemorrhagic or infectious complications. Of the 10 patients who achieved CR, 1 died after 1 week from heart failure, 5 relapsed respectively 17, 20, 21, 21, 42, weeks after ABMT, 4 are still in CR after 2+, 14+, 17+, and 120+, weeks. Of the 9 patients treated with BAVC regimen, 8(88.8%) achieved CR. Four patients relapsed after a median of 19.7 weeks and 4 are still in complete remission. Of interest is the fact that the second complete remission of one patient is longer than the first one, despite the fact that marrow was not purified by any in vitro treatment. In conclusion we can say that BAVC regimen is highly effective in obtaining second complete remission in patients with AML and prolonged disease free survival can be achieved at least in a small number of cases.

Abstract
Eight patients with overt central nervous system (CNS) leukemia and lymphoma were treated with sequential administration of systemic high-dose cytosine arabinoside (HiDAC) and asparaginase (ASP) with no direct CNS therapy. Complete clearing of the cerebrospinal fluid (CSF) was achieved in six (86%) of seven patients with meningeal disease, generally after the first course of therapy. Two patients presented with evidence of extensive intracerebral disease; both responded with a greater than 50% regression of the tumor infiltrates. Concomitant extraneurologic localizations responded equally well to HiDAC/ASP: responses were seen in four of five patients, including complete remission in three of four patients who presented with marrow involvement. Toxicity was generally moderate and limited to myelosuppression (eight of eight patients), tolerable nausea and vomiting (eight of eight patients), mild hepatotoxicity (two of eight patients), and oral mucositis (one of eight patients). These results indicate that HiDAC/ASP is a tolerable and highly effective treatment modality for CNS leukemia and lymphoma and suggest its potential role for sanctuary chemoprophylaxis.

Abstract
E-rosetting of leukaemic blast cells is one of the markers of T-cell acute lymphoblastic leukaemia (ALL). In children, E+ ALL has a bad prognosis. In adults, data are scarce. This report provides information on 25 E+ ALL adult patients who have a minimum follow-up time of 36 months. Twenty-two of 25 patients (88%) achieved complete remission (CR) (median duration 16 months), and six of them were alive, relapse-free, and off therapy after 36-81 months, with a 26% projected 6-year relapse-free survival. In 97 patients with E-SmIg- ALL, who were treated at the same Institutions, over the same period of time, and by the same modalities, the outcome of therapy was almost identical: CR 80%, median duration of first CR 15 months, projected 6-year relapse-free survival 15%. The white blood cell (WBC) count at presentation influenced significantly and to the same degree first CR length in both E+ and E- cases. In this adult series, WBC count was not as high as in children. Moreover, a high Hb concentration, a very high WBC count, lymphadenomegaly, and mediastinal involvement, were found more frequently in adolescents and young adults than in adults. Based on these data, it is suggested that in adults E-rosetting as such is not a marker of a poorer prognosis, that some of the typical features of children E+ ALL weaken with age, and that in adults the disease can have a less aggressive character.

Abstract
Among 164 patients with acute lymphoblastic leukemia (ALL) (age greater than 11 years) induced into complete remission at four hospitals in Italy and The Netherlands between 1971-1977, 49 survived for more than three years in continuous complete remission. Features at diagnosis of the 49 long-term survivors were compared with those of the parent group. The long-term survivors presented with significantly lower leukocyte counts and were slightly younger. Late relapses occurred in nine patients after 37-91 months from remission. Of the 45 patients who had all treatment stopped after 24-60 months of continuous remission, seven have relapsed. Relapses, mainly in the marrow, occurred 4-32 months after cessation of therapy, the risk of relapse being greatest in the first year and dropping to zero by the fourth year. ALL appears curable in approximately one fifth of adolescents and adults entering complete remission with adequate chemotherapy.

Abstract
The case histories of 293 adolescent and adult patients with acute lymphoblastic leukemia (ALL) first seen and treated between 1969 and 1979 are reviewed. A complete remission (CR) was achieved in 79% of cases. Male sex, advanced age (greater than or equal to 30 yr old), and early CNS involvement were the major determinants of remission failure. Median duration of first CR was 16 mo, with 23 patients (actuarial proportion 25%) alive and relapse-free at 5 yr. The major determinant of first CR length was white blood cell (WBC) count (best cut-off value at 35 X 10(9)/liter). First CR length was also negatively affected by early CNS involvement, morphological FAB L3 subtype, and B-cell (Smlg+) leukemia, but these features were significantly associated with a high WBC count. First CR length in patients 11-15 yr old did not differ significantly from that of patients 16-59 yr old. The negative prognostic value of T-cell (E+) leukemia was not confirmed in this adult series. CNS prophylaxis provided an effective protection against CNS relapse. Maintenance chemotherapy was apparently more effective when 4 or more than 4 drugs were employed. "Low risk" patients (WBC count less than 35 X 10(9)/liter still relapsed rather frequently (32% at 1 yr, 49% at 2 yr), with 33% of them alive and relapse-free at 5 yr. "High risk" patients (WBC count greater than or equal to 35 X 10(9)/liter +/- early CNS involvement +/- morphological L3 subtype +/- B-cell leukemia) relapsed very quickly (50% at 6 mo. 70% at 1 yr), with only 6% of them relapse-free at 5 yr.

Abstract
A phase II evaluation of vindesine (VDS) was carried out in 46 patients with hematologic malignancies refractory to conventional chemotherapy. Two VDS schedules were employed (at random): (A) a weekly bolus (5 mg/m2 i.v. X 4); (B) fractionated daily injections (0.5 mg/m2 i.v. q.12 h X 10, course to be repeated after 10-15 days). Complete and partial remissions were observed in acute lymphocytic leukemia (3/14 patients), acute non-lymphocytic leukemia (2/12 patients), chronic myelocytic leukemia in blastic crisis (4/12 patients) and non-Hodgkin's lymphoma (4/8 patients). Responses were seen with higher frequency in patients treated with the weekly bolus (42.8 vs 16%). Myelosuppression was the most relevant side effect in both schedules. Neurotoxicity occurred infrequently and was generally mild in degree. Further trials with VDS in combination with other drugs are recommended in hematologic malignancies.

Abstract
38 children with acute lymphocytic leukaemia (ALL) in haematologic relapse were retreated with vincristine, daunomycin and prednisone (VPD) together with intrathecal methotrexate and prednisone, followed by asparaginase in those patients not in complete remission after 4 weeks. The overall complete remission (CR) rate was 79%; asparaginase was needed to achieve CR in 7 of the 30 responding patients. The median duration of second remission was only 36 weeks, but 6 out of 15 children receiving the COAP-POMP-CART consolidation regimen remain in continuous second remission after 37-260 weeks; 3 of them are currently off all therapy. It is concluded that a prolonged second remission can be achieved in children with ALL in bone marrow relapse by combining intensive chemotherapy with the prevention of meningeal leukaemia.

Abstract
The results of discontinuing therapy in children with acute lymphocytic leukemia observed at four associated institutions are presented. Of the 247 patients who achieved complete remission, 122 (49.3%) reached the point of discontinuing therapy after 2-4 years of continuous remission. The median period off therapy was 13 months with a range of 1-69 months. Of the 122 children removed from therapy, 27 (22.1%) relapsed, mainly in the bone marrow; relapses occurred 1-32 months after cessation of therapy (median ten months) with only two relapses occurring later than two years. By actuarial analysis, 57% of the patients are projected in continuous remission after five years from cessation of therapy. Neither selected features at diagnosis nor single modalities of treatment were found to predict whether relapse would occur after discontinuing therapy. Long-term remission and possibly cure can be expected in over one-third of newly diagnosed children with ALL after 2-4 years of antileukemic treatment.
