To investigate effects of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on lymphoid cells in vivo, we monitored changes in absolute lymphocyte counts, plasma concentrations of soluble interleukin-2 receptor (sIL-2R) and soluble cytotoxic/suppressor (sCD8) antigens, and phenotypic changes of surface membrane antigens of peripheral mononuclear cells from 14 patients with malignant lymphoma treated with rhGM-CSF. Eight of the 14 patients had relapsed or had refractory non-Hodgkin's lymphoma (NHL) and received rhGM-CSF after intensive chemotherapy with novantrone (NO) and high-dose Ara-C (AC) (NOAC) as salvage regimen. Six other patients with NHL or Hodgkin's disease (HD) were in complete remission and treated with rhGM-CSF to enhance peripheral hematopoietic progenitor cell harvest for autografting. An increase in absolute lymphocyte count at the zenith of leukocyte elevation and a drastic increase in concentration of sIL-2R from a median of 565 U/mL to 6,700 U/mL on rhGM-CSF infusion were found in all patients. There was also a moderate increase in sCD8 levels from a median of 277 U/mL to 470 U/mL. Ten patients were available for serial studies of phenotypic changes in surface membrane antigens. A significant increase in CD25+ (IL-2R+) (P = .0020) and CD4+ (P = .0137) lymphocytes was observed in all patients, but no significant change in CD3+, CD8+, TCR delta 1+, or CD19+ cells. Elevations in absolute lymphocyte counts or in concentrations of sIL-2R or sCD8 were not observed in four other patients during recovery from intensive chemotherapy without rhGM-CSF support. Our results provide evidence that administration of rhGM-CSF might activate lymphocytes in vivo. The impact of this activation on the remission rate and duration, as well as survival in patients with NHL, warrants further investigation.

Previous study has shown that the combination of mitoxantrone (Novantrone, NO) and Ara-C (AC) (NOAC) was active in refractory non-Hodgkin's lymphoma (NHL) but myelosuppression was dose-limiting. In a pilot study, we investigated the effects of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) after NOAC chemotherapy in patients with refractory NHL. NO was applied at a dosage of 10 mg/m2/day on days 2 and 3 and AC at 3 g/m2/12h on days 1 and 2. RhGM-CSF was administered at 250 ug/m2/day as a continuous i.v. infusion from day 6 until the neutrophils were greater than 3.0/nl for 3 consecutive days. Twenty-three patients from five of the nine participating centers were treated with NOAC chemotherapy plus rhGM-CSF, whereas 14 patients from the other four centers received chemotherapy alone. With rhGM-CSF, the median duration of severe neutropenia (less than 0.5/nl) after NOAC was 8 days versus a median of 13 days without rhGM-CSF (P = 0.0058), and that of thrombocytopenia (less than 20.0/nl), 3 days versus 7 days (P greater than 0.4, NS). The rates of infections and stomatitis were 25% and 17%, respectively, for patients treated with rhGM-CSF as compared to 53% (P = 0.0547, NS) and 60% (P = 0.0078), respectively, without rhGM-CSF. The following side effects were associated with the administration of rhGM-CSF: pleural and/or pericardial effusions in five patients, thrombosis in two patients, bone pain in two patients, and respiratory distress syndrome in one patient. A complete remission was achieved in nine of the 23 patients treated with NOAC plus rhGM-CSF, and in two of the 14 patients treated with chemotherapy alone. The median survival of patients treated with rhGM-CSF was not reached at 400 days and seemed to be longer than that of patients treated with chemotherapy alone (median, 109 days; P = 0.036). RhGM-CSF after chemotherapy can be applied safely to patients with NHL, shorten the period of severe cytopenia, reduce the rates of stomatitis, and did not seem to cause adverse effects on response.

Neutrophilic eccrine hidradenitis (NEH) is a recently recognized dermatosis occurring in patients receiving chemotherapy for a variety of malignancies. We report the second pediatric case. An 11-year-old boy with non-Hodgkin's lymphoma developed widespread erythematous papulopustules beginning two days after receiving high-dose cytarabine (Ara-C) in preparation for a bone marrow transplant. The lesions spontaneously regressed in two weeks. Histologic examination revealed a neutrophilic infiltrate around and within the eccrine ducts and secretory coils. Bacterial, fungal, and viral cultures were negative. These findings are characteristic of NEH. The condition should be differentiated from infectious dermatoses that may require treatment.

Knowing the good penetration of systemic HDara-C into the CNS, we treated with this approach overt meningeal leukemia, either isolated or with bone marrow (BM) disease, in 31 adults: 18 ALL, 4 ANLL, 1 lymphoid blast crisis of CGL (LBC-CGL), and 8 non-Hodgkin's lymphoma (NHL). Treatment consisted of Ara-C, 3 g/m2 i.v. q 12 h, by 3 h infusion for 8 doses, followed by 4 doses at day 21. Complete remitters received consolidation with four monthly 4-dose courses of HDara-C. Additional multidrug consolidation and direct CNS therapy with intrathecal (i.t.) methotrexate (MTX) or Ara-C +/- cranial RT was administered to the 11 remitters last treated. Twenty of 31 patients (64%) achieved CR: 10/10 with isolated meningeal leukemia and 10/21 with concurrent CNS and BM disease. Of the remaining 11 patients, 8 had cerebrospinal fluid (CSF) clearing with persistent BM disease. In all cases but one CNS symptoms resolved promptly. CR median duration was 6 months (range 2 to 20). The main toxicity was myelosuppression requiring intensive support. There was no neurologic toxicity. These results show that systemic HDara-C is highly effective in acute leukemias and NHL with CNS involvement, and suggest the utility of this regimen for sanctuary chemoprophylaxis in patients at high risk for CNS disease.

Mitoxantrone (Novantrone, NO) and high-dose cytarabine (Ara-C, AC) have each been shown in monotherapy trials to be active in non-Hodgkin's lymphoma (NHL). In the current study, a combination of the two drugs (NOAC) was administered to 31 patients with advanced NHL refractory to modern sequential chemotherapy regimens. Ara-C was administered at 3 g/m2 as a 3 hour infusion every 12 hours on day 1 (2 doses) and mitoxantrone at 10 mg/m2/day on days 2 and 3. Of the 18 patients with high-grade malignant NHL, six have attained a complete remission (CR) and two, a partial remission (PR). One CR and 5 PRs were achieved among the other 13 patients with intermediate or low-grade NHL. The median time to relapse (TTR) of patients achieving CR was 7 months with a range from 4 to 17 months. Myelosuppression with subsequent infections was the major toxicity of this regimen. The median duration of severe neutropenia (less than 0.5/nl) was 9 days with a range of 0 to 27 days and the median duration of severe thrombocytopenia (less than 20/nl), 5 days with a range of 0 to 35 days. Infectious complications during cytopenia was seen in 45.3% of the courses administered and fever of unidentified origin was seen in 42.3%. About 63% of the patients were hospitalized for intravenous antibiotic or antimycotic treatment. Other side effects were mild and included nausea, stomatitis, and transient tachycardia of greater than 100/min. Thus, this regimen was active in refractory NHL with poor prognosis, and the toxic side effects were not excessive. Evaluation of the activity of this regimen at higher dose levels of Ara-C is warranted.

Twenty-three children with refractory or relapsed non-Hodgkin's lymphoma (NHL) received high-dose methotrexate (HD-MTX), and 9 received Ara-C by continuous intravenous infusion, as phase II studies. They all had previously received a protocol including vincristine, adriamycin, cyclophosphamide, IV push Ara-C, asparaginase, intrathecal MTX, and cranial irradiation, and had failed to respond or had relapsed. HD-MTX was given at the dose of 6 g/m2 or more with leucovorin rescue, Ara-C at the dose of 100 mg/m2/day by continuous infusion over 10 days. Among the 22 evaluable patients receiving HD-MTX, 10 responses (7 CR; 3 PR) were observed. Among the 9 patients receiving Ara-C, 4 responded (1 CR; 3 PR). Toxicity in those previously heavily treated patients was acceptable. These two drugs are now successfully included in childhood NHL treatment protocols.

Increased dosages of cytosine arabinoside (Ara-C) have been shown to be active in remission induction and consolidation treatment of patients with primary refractory acute lymphoblastic leukemia (ALL) and lymphoblastic non-Hodgkin's lymphoma (lyNHL). From August 1983 to December 1986 we treated 25 patients with ALL (9) and lyNHL, stage III and IV (16), median age 22 (range 15-48 yr) with a protocol consisting of remission induction with vincristine, prednisone, adriamycine and Ara-C (1 g/m2 twice daily as 2-h infusion d1-6) and intrathecal methotrexate, followed by consolidation courses with vincristine, prednisone, adriamycine and Ara-C (3 g/m2, twice daily as 2-h infusion d1-4) and intrathecal methotrexate. Some patients received CNS and/or mediastinal irradiation. No maintenance was given. 18 patients (72%) achieved complete remission (5 of the 11 previously treated and 13 of the 14 previously untreated patients). Consolidation courses were given to 17 patients. 5 of them relapsed in the bone marrow (3), skin (1) and CNS plus bone marrow (1) at 5, 5, 6, 6 and 24 months. The duration of complete remission ranged from 5 to 51+ months; the median could not yet be calculated. Short-term intensive treatment might be a worthwhile approach for ALL and lyNHL.

Sixty-four patients underwent 66 remission induction courses with intermediate-dose cytosine-arabinoside (Ara-C) for treatment of acute myelogenous leukemia, acute lymphoblastic leukemia, or high-grade malignant non-Hodgkin's lymphoma. The Ara-C was administered in combination with amsacrine with or without VP16-213 and prednisone. After complete remission was achieved, 27 patients received 38 consolidation courses consisting of high-dose Ara-C either alone or in combination with amsacrine with or without VP16-213 and prednisone. Seven (11%) of 66 induction courses and eight (21%) of 38 consolidation courses were complicated by respiratory failure that was considered a pulmonary reaction to Ara-C therapy. The initial findings on chest radiographs in the 15 cases included a diffuse interstitial pattern (two), a mixed interstitial-alveolar pattern (eight), an alveolar pattern (three), and a normal pattern (two). In 11 cases, the abnormalities were diffuse throughout both lungs with a preference for the lower lobes in five. The changes were localized in two cases. A small pleural effusion was observed in two patients. In the majority of cases, the initial radiographic changes progressed to a predominantly alveolar pattern. Thirteen patients recovered clinically within 2-9 days, and two patients died of pulmonary complications. Radiologic recovery took 7-21 days. Rapid regression of alveolar consolidations within 3-7 days was the first sign of radiologic improvement. The interstitial pattern gradually regressed. We conclude that the spectrum of radiologic abnormalities in cases of pulmonary reaction to Ara-C therapy includes diffuse interstitial, mixed interstitial-alveolar, or alveolar pulmonary changes.

There has been a striking improvement in the overall numbers of children and adolescents who become disease-free and remain disease-free as a result of intensive therapy as defined today, for the following cancers: acute nonlymphocytic leukemia (ANLL), non-Hodgkin's lymphoma (NHL), poor risk acute lymphocytic leukemia (ALL), osteosarcoma, and Ewing's sarcoma. The therapy for each of these tumors, with the exception of osteosarcoma, consisted of combination chemotherapy with or without radiotherapy and was started as soon after diagnosis as possible. Aggressive therapy of osteosarcoma has consisted of surgical removal of lung metastases and chemotherapy. Intensive chemotherapy recently has included the use of high doses of certain drugs such as cytosine arabinoside (Ara-C), methotrexate, VP-16-213 and melphalan in the treatment of patients with tumors that are currently difficult to treat.

High-dose Ara-C consolidation therapy for patients with primary refractory or relapsed acute leukemia (AML and ALL) or relapsed lymphoblastic non-Hodgkin's lymphoma (LNHL) was investigated. Between January 1983 and January 1986, 47 adult patients with primary refractory or relapsed AML, ALL or lymphoblastic NHL received a remission induction regimen that included intermediate-dose Ara-C (lg/m2/2hr q 12hr X 12). Of the twenty-nine (61.7%) patients who achieved complete remission sixteen (AML 9, ALL 5, LNHL 2) received 1-3 consolidation courses that included high-dose Ara-C (3g/m2/2hr q 12hr X 8). Three patients died as a result of major infections during the pancytopenic phase that followed the first consolidation course and 6 relapsed at 4, 4, 6, 8, 9 and 16 months; at the moment of this report the remaining 7 patients have been in continued remission for 8 to 28 months (6 have been in continued complete remission for greater than or equal to 11 months). The predicted median disease-free interval for patients who survived consolidation therapy is 16 months. Of the 13 patients who did not undergo consolidation chemotherapy 2 subsequently underwent allogeneic bone marrow transplantation and 3 died as a result of major infectious complications while in complete remission. Eight patients received no further treatment because they refused or had previously experienced severe toxicity. The median disease-free interval for this group was only 3 months. Our preliminary data on brief intensive consolidation therapy for patients with relapsed or primary refractory leukemia or non-Hodgkin's lymphoma suggest that this kind of treatment prolongs disease-free interval.
