We have treated 20 adult patients with acute lymphoblastic leukemia (ALL) and 2 patients with lymphoblastic lymphoma with a protocol modified from L-10M of the Memorial Sloan Kettering Cancer Center. Eighteen patients (81.8%) entered complete remission (CR). Eight of them eventually relapsed (only 1 patient had a meningeal relapse) and died. Median CR duration was 19 months (median overall follow-up of 35 months and 50% remission duration was not yet determined. Median overall survival was 19 months. Three patients died of sepsis during remission induction, but all of other deaths were due to resistant or relapsed leukemia. The four patients who completed 3.5 year's modified L-10M protocol were free from relapse for 6-11 months (mean 8.7). Although further follow-up is necessary, we suggest that modified L-10M protocol is effective for adult ALL and long-term survival may be available.

The application of autologous bone marrow transplantation (ABMT) in treating acute leukemias in children has been limited by the presence of residual occult viable leukemic cells in the marrow cell suspension. One approach to this problem is the ex vivo treatment ("purging") of the autograft to eradicate these tumor cells yet spare the normal lymphohematopoietic stem cells. Initial studies of acute myeloid leukemia (AML) in a rodent model demonstrated that incubation with 4-hydroperoxycyclophosphamide (4HC), a congener of cyclophosphamide and an active alkylating agent in aqueous solution, could effectively eliminate viable AML cells from marrow cell suspensions without apparent toxicity to normal stem cells. We have conducted clinical trials of ABMT with 4HC-treated marrow in children with acute leukemia in remission; marrow was collected, treated ex vivo with 4HC (100 micrograms/ml), and cryopreserved in liquid nitrogen until reinfusion. Children received pre-ABMT conditioning with either high-dose cyclophosphamide and total body irradiation (CY-TBI) for acute lymphocytic leukemia (ALL) or high-dose busulfan and cyclophosphamide (BU-CY) for AML. Of nine children who underwent ABMT with 4HC-treated marrow for ALL in second complete remission (CR2), all relapsed (eight in the marrow, one in the central nervous system) at a median of 5 months (range, 2-17) after ABMT and all have died with relapsed ALL or as a consequence of its treatment. Twenty-nine children with AML (five in CR1, 24 in CR2) received autografts with chemopurged marrow at a median remission duration of 3 months (range, 2-15). Three patients died from sepsis during aplasia; 10 children (one in CR1 and nine in CR2) relapsed with AML at a median of 7 months (range, 2-23) after ABMT, for an actuarial relapse rate of 47%. Sixteen patients with AML (four in CR1, 12 in CR2) are in unmaintained remission at a median of 16 months (range, 6-102) after ABMT, for an actuarial disease-free survival of 49%. Although ABMT with 4HC-treated marrow appears to have a limited role in the treatment of children with ALL who lack a suitable related donor, the results in AML are encouraging and compare favorably with both syngeneic and allogeneic BMT in similar groups of patients.

We previously administered ara-C at a dose rate of 250 mg/m2/hr for 36-72 hr to patients with leukemia. Gastrointestinal toxicity was dose-limiting. This regimen was modified to an every other day schedule, administering 24-hr periods of high dose continuous infusion ara-C, each followed by a 24-hr rest period. Sixteen patients with relapsed/refractory acute myeloid leukemia (AML) (N = 4), secondary AML (N = 2), relapsed/refractory acute lymphoblastic leukemia (N = 7), or CML in blast crisis (N = 3) received this regimen of three 24-hr infusions with two intercurrent 24-hr rest periods. Grade 3 gastrointestinal toxicity was encountered in 57% of the courses, and hypoplasia was achieved in all patients. Three of the patients died while hypoplastic, two with septicemia and another with intracranial hemorrhage. There were five responding patients (2 CRs, 3 PRs). Median steady-state plasma ara-C levels were 24 microM, 22 microM, and 20 microM during the first, second, and third 24-hr infusions, respectively. Ara-C levels ranged from 4-118 microM during the infusions and were always below 4.5 microM during the rest periods. A significant level of ara-C incorporation into DNA was detected in each of the five patients studied, thus demonstrating that (ara-C)DNA formation is detectable in blasts from patients receiving high dose continuous infusion ara-C therapy. These findings suggest that alternate day continuous infusion ara-C may be useful in the treatment of acute leukemia and CML in blast crisis.

A 46-year-old woman was admitted to our hospital because of leukocytosis. A diagnosis of acute lymphoblastic leukemia (FAB: L2 type) was made by reviewing peripheral blood smear and bone marrow aspirate. Chromosome analysis showed the presence of Philadelphia chromosome. A combination chemotherapy with L-asparaginase, doxorubicin, vincristine, and prednisolone was started, but complete remission was not achieved. During a neutropenic period after combination chemotherapy with doxorubicin, vincristine, vinblastine, and VP-16, high fever and tender swelling of the right cheek were noticed. A diagnosis of maxillary sinusitis was made with tomography and CT scan of the maxillary sinus. Since culture of the aspirate from the maxillary sinus grew aspergillus, a diagnosis of aspergillosis of the maxillary sinus was made. Immediately after the intravenous administration of amphotericin B and the lavage of the sinus with amphotericin B was started, high fever subsided and clinical improvement was observed. Several regimens of chemotherapy failed to obtain hematological remission, she died of sepsis of Enterobactor cloacae without evidence or relapse of dissemination of aspergillosis after initial successful treatment. While a few cases with aspergillus maxillary sinusitis were reported in leukemic patients, the possible occurrence of this complication must be kept in mind in a severe neutropenic period after intensive chemotherapy. The combination of intravenous administration and local lavage of amphotericin B appeared to be an effective treatment in the Aspergillus maxillary sinusitis.

The efficacy and safety of a combination regimen using cefmetazole (CMZ) and netilmicin (NTL) were evaluated in the treatment of infections complicated with hematological disorders. Primary diseases in 31 patients included in the evaluation were acute myelocytic leukemia (3 cases), acute lymphocytic leukemia (2 cases), malignant lymphoma (14 cases), chronic myelocytic leukemia (2 cases), chronic myelocytic leukemia blast crisis (4 cases), myelodysplastic syndrome (2 cases), aplastic anemia (3 cases), and malignant histiocytosis (1 case). Complicated infections included 29 cases of suspected septicemia, 1 case of septicemia and 1 case of pneumonia. Clinical responses were excellent in 6 (19.4%), good in 12 (38.7%), fair in 1 (3.2%) and poor in 12 (38.7%). The total clinical efficacy rate was 58.1%. No significant effect of initial neutrophil counts was observed on response rates. Patients who showed increasing neutrophil counts during therapy had higher response rates than those in whom the neutrophil count decreased or remained unchanged at levels less than 500/mm3 in after neutrophil counts. No side effects were observed in any of the 31 patients. In conclusion, this combination therapy of CMZ and NTL thus appears to be useful and safe in therapies for infections complicated with hematological disorders.

Sepsis due to Candida parapsilosis with involvement of the joints and the lungs, respectively, is reported in two patients with acute leukemia. The first patient had ankle arthritis 72 days after an allogenic bone marrow transplant for acute lymphoblastic leukemia. The second patient had pneumonia with cavitation during pancytopenia after chemotherapy for acute monocytic leukemia. In both cases, C. parapsilosis sepsis responded to therapy with amphotericin B, associated with miconazole in the first patient and with 5-fluorocytosine in the second one. The rarity of septic foci during C. parapsilosis fungemia and the good outcome of both patients are emphasized. This good result was probably due to early antifungal therapy and the relatively rapid recovery of granulocytopenia.

Pulmonary malacoplakia is a rare condition with only five previously reported cases in the literature, all occurring in adults. We describe a case of malacoplakia of the lung in a 6-year-old female with acute lymphoblastic leukemia in remission and a Rhodococcus equi pneumonia and septicemia. The case demonstrates that pulmonary malacoplakia can occur in immunocompromised pediatric patients and that malacoplakia should, therefore, be added to the list of causes of nodular lung infiltrates in immunocompromised children.

A national childhood acute lymphoblastic leukemia (ALL) study was initiated in Israel in 1984 with the aim of improving results in difficult aspects of treatment including: high-risk groups, the problems of late relapses, and the effect of cranial irradiation for CNS prophylaxis in leading to late neuropsychiatric sequelae and secondary tumors. Induction of chemotherapy with a combination of 6 drugs (vincristine, cyclophosphamide, cytosine arabinoside, adriamycin, prednisone and L-asparaginase), followed by intensification with methotrexate and L-asparaginase, was introduced in both the usual and the high-risk groups. In a selected group with better prognostic factors, therapy was reduced. In an attempt to minimize the sequelae of CNS prophylactic therapy, cranial irradiation was omitted in half the patients and intrathecal (IT) triple therapy was given instead. Following 2 years of unsatisfactory preliminary results in a very high-risk group (VHR; non-T- and T-cell leukemia with WBC counts of greater than 100,000 and greater than 20,000, respectively), treatment was modified and intensified. Between Nov. 1984 and Feb. 1989, 143 patients were enrolled from 10 hospitals. During follow-up of a median of 2.5 years, there were 32 failures (2 failed remissions, 27 relapsed and 3 died of bleeding and sepsis). 107 patients are alive in first remission and an additional 8 in second and third remissions. By Kaplan-Meier life table analysis, the rates of leukemia-free interval (LFI) and event-free interval (EFI) for 4 years were 60% and 57%, respectively. Improved LFI results of 71% for 4 years were achieved in a group with non-T-cell ALL with WBC less than 100,000 (the largest group, 65% of the patients). In the small "good risk" group (10% of patients), and the T-cell group with WBC less than 100,000, LFI for 4 years were 56% and 54%, respectively. In the VHR group, modification seemed to have improved results: LFI of 41% for 3 years. CNS prophylaxis with IT triple therapy was as effective as cranial irradiation in the standard risk group. In 1 out of 33 children on this protocol a single CNS relapse occurred, as compared to 2 out of 35 matched controls with cranial irradiation. These results warrant extension of IT triple therapy to higher risk groups of childhood ALL. As for systemic treatment, increased up-front high-dose intensive therapy is recommended for all groups with ALL, but with reduction of cumulative dose to minimize late effects.

In the present study plasma fibronectin levels were determined in patients with hematopoietic malignancy, particularly leukemias, in an effort to clarify their clinical implications. Among leukemia patients, those with AML, ALL, ATL or CLL had various plasma fibronectin levels that were higher in some cases, while lower in others, as compared to normal control values. An elevation of the fibronectin level was noted often in APL, while lower fibronectin values were observed in many instances of CML. In these types of leukemia, acute exacerbation as well as supervention of infection tended to be associated with lower than normal levels of fibronectin. An especially marked depression of fibronectin occurred, when leukemia was complicated by sepsis or DIC, in which a good parallel was noted between the progress of disease and the fibronectin level. In lymphoproliferative diseases, the fibronectin value varied widely, but low fibronectin levels were frequently associated with intercurrent infection or an extreme deterioration of the general physical conditions.

Thirty-one patients affected by advanced ALL entered this study. Twenty (1 in I CR, 9 in II CR, 6 in III CR and 4 extramedullary relapses) were treated with the BMVC conditioning regimen. Eleven (9 in II CR, 2 in III CR) received the Busulfan plus Cytoxan conditioning regimen. Asta-Z 7654-purged marrow was reinfused at day 0. Both protocols were well tolerated. Two patients treated with the BMVC regimen died in aplasia from sepsis; 1 patient died in CR 5 months after transplantation, 13 relapsed after a median time of 4 months (range 1-31). Four patients are in CCR with a median follow-up of 16 months (range 11-24). In the BU + CY treated group no toxic deaths were observed. Four patients relapsed after a median of 3 months (range 2-7) and 7 are in CCR with a median follow-up of 5 months (range 2-28).
