Combined total body irradiation (TBI) and Prednimustine were prospectively evaluated in 30 patients affected either with chronic lymphocytic leukemia (CLL) or with low-grade non-Hodgkin's lymphoma (NHL) eleven patients were previously treated. Between January 1984 and May 1987, 20 evaluable patients with CLL, median age 66 years (range 43-82), classified according to Rai (4 in stage I, 10 in stage II, 4 in stage III, 2 in stage IV) and 10 evaluable patients with NHL low-grade malignancy according to the Working Formulation, Stages III and IV, median age 54 years (range 32-71) were treated using a 6 MeV Linear Accelerator, applying two opposite alternating fields including total body, with a fraction of 15 cGy, 2 fractions weekly (3-day interval) for a total dose of 150 cGy given over 5 weeks. Prednimustine (100 mg/m2, orally, for 5 consecutive days, every 3-4 weeks, for 6-9 courses) was administered 2 months after TBI treatment, as consolidation therapy. By May 1989, a total of 85% hematological responses (defined as normalization of the differential white cell count, of the total blood cell count and of bone marrow infiltration) were obtained after combined treatment in CLL patients; moreover 3 CR (according to the WHO criteria), 75% with splenomegaly reduction and 40% with lymphadenopathy reduction were seen. Ninety percent objective responses (5 CR and 4 PR) were observed in the NHL patients, with 50% having splenomegaly reduction and 67% lymphadenopathy reduction. The median response time in the two groups was, respectively, 14 and 23 months. The overall toxicity (WHO grades 1,2,3,4) after combined treatment was 65% and 70% in the two patient groups. WHO grade III toxicity, completely reversible, was verified in only 16.6% of the cases; all cases, except one, were previously treated. Additionally, 1 toxic death (grade IV thrombocytopenia and leukopenia) was observed in a heavily pretreated patient affected with CLL after TBI alone. Prednimustine regimen was generally well tolerated. The high response rate and acceptable toxicity, confirms the feasibility and the usefulness of TBI in the context of a combined treatment for CLL and low-grade NHL patients. However in order to further reduce the severe toxic side effects, observed in one patient, white blood cells and platelet count should be plotted and monitored carefully, particularly in pretreated patients.

Retrospective analysis of 45 patients (33 females, 12 males) with cytologically-proven malignant ascites is presented. Abdominal pain was the most frequent symptom (69%). Fiftythree percent cases had low serum albumin. Ascitic fluid was haemorrhagic or serosanguinous in 48% cases, in the rest it was clear or straw-coloured. Peritoneal effusion was exudative in 84% cases. Mean glucose content of ascitic fluid was 95 mg/dl and the mean white cell count of 919 cells/cmm. Vast majority (82%) of the cases had metastatic adenocarcinomas. Primary malignancy was mostly ovarian (47%) followed by non-Hodgkin's lymphoma (11%) and gall bladder carcinoma (9%). Primary site could not be identified in 13% cases. Sixty-two percent patients received systemic chemotherapy for the underlying malignancy, of these 43% had complete or partial resolution of the ascites. Of the patients whose long-term follow-up is available, 54% were alive with a median follow-up of 9 months.

Between 1979 and 1987 the Scotland and Newcastle Lymphoma Group registered 972 adults with Working Formulation high or intermediate grade non-Hodgkin's lymphoma. Clinical, pathological and investigational data were recorded prospectively on a computer database allowing analysis for prognostic factors. We have derived prognostically important characteristics and have tested prospectively the validity of the prognostic index on a geographically distinct sub-set of patients from the Edinburgh/Borders clinics. Multivariate analysis showed the following factors to be important in declining order of power; advancing age, worsening performance status, CNS/liver involvement, abnormal white cell count, 'B' symptoms and advancing clinical stage. Patient individual scores allowed them to be aggregated into one of three distinct prognostic groupings separated by arbitrary cut-points into a Best Group (39%) where the median survival exceeds 5 years (53% alive at 5 years), an Intermediate Group (30%) with median survival of 21 months (21% alive at 5 years), and a Worst Group (31%) whose median survival is 7 months (8% alive at 5 years). Similar prognostic group separations occurred when analysis was confined to: patients younger than 70 years; patients treated with initial chemotherapy; patients treated with initial radiotherapy; patients within any of the major pathological sub-groups.

The effect of white cell depletion of red cells and platelet concentrates on the transmission of cytomegalovirus (CMV) was studied retrospectively in 150 patients treated intensively for acute leukemia or non-Hodgkin's lymphoma. CMV infection was diagnosed on the basis of IgM and IgG antibody responses to CMV late antigen (CMV-LA). Before cytoreductive therapy for their underlying disease, 59 patients were CMV seronegative and 91 were CMV seropositive. None of the 59 CMV-seronegative patients showed persistent seroconversion 2 months after the cytoreductive treatment. The comparison group, consisting of 312 cardiac surgery patients, showed a significantly higher incidence of primary CMV infections: 10 of 86 (11.6%, p = 0.004). Twenty-five percent of the CMV-seronegative patients and controls had transient IgG antibodies to CMV-LA without IgM antibodies, which is indicative of antibodies passively acquired via blood products. These results indicate that white cell-poor blood products carry a very low risk, if any, of CMV transmission. The policy of transfusing white cell-poor blood products provides a useful alternative to the selection of CMV-seronegative donors.

Two consecutive patients with acute myeloid leukaemia (AML) developed severe probable graft-versus-host disease (GVHD) following transfusion of blood products from normal donors. In one patient the AML had arisen de novo, while in the other it occurred four years after the patient developed non-Hodgkin's lymphoma (NHL) and was treated with radiotherapy and combination cytotoxic chemotherapy. Both patients received anti-leukaemic treatment with doxorubicin and cytosine arabinoside and intensive haematological supportive care with transfusions of red cell, white cell and platelet concentrates obtained from normal donors. Clinically the GVHD in each patient was manifest by a severe erythematous rash, intractable diarrhoea and abnormalities in the liver function tests. On pathological examination the skin in each case showed the typical changes of GVHD. Both patients died. There have been few previous reports of GVHD occurring after accidental engraftment of immunosuppressed patients undergoing therapy for acute leukaemia. Our experience suggests that it may occur more often than has hitherto been recognised. At present there is controversy concerning the possible anti-leukaemic effects of granulocyte transfusions. Until the relative importance of the benefits and deleterious effects of cells with the potential for engraftment is determined by further studies, we recommend the routine irradiation of all cellular blood products intended for administration to acute leukaemia patients undergoing intensive cytoreductive chemotherapy.

Four of 12 Chinese patients receiving BACOP, in combination with recombinant human granulocyte colony-stimulating factor, for aggressive non-Hodgkin's lymphoma developed a rapidly progressive pneumonic illness characterised by diffuse pulmonary infiltrates and hypoxaemia. The condition proved fatal in three, and in none could an infective cause be identified. A retrospective analysis revealed only one episode of pneumonia in the previous 24 patients in whom the same BACOP regimen was administered without granulocyte colony-stimulating factor support. Granulocyte colony-stimulating factor, by augmenting white cell production, pulmonary sequestration and margination and production of toxic oxygen species, may exacerbate underlying subclinical bleomycin pulmonary toxicity. Caution should be exercised before using granulocyte-stimulating factors in bleomycin-containing regimens.

The aim of this study was to examine the effect of G-CSF given after salvage chemotherapy on the mobilisation of peripheral blood progenitor cells (PBPC) in pretreated patients. Seven patients with relapsed or refractory non-Hodgkin's lymphoma (NHL) were treated with methotrexate, cyclophosphamide, cytarabine, etoposide and dexamethasone. G-CSF was given at a dose of 3.8-7.2 micrograms/kg (1-2 ampoules) daily by subcutaneous injection from the onset of neutropenia (< 1.0 x 10(9)/L). A median of 3 leukaphereses was performed when the white cell count was recovering. The median number of granulocyte-macrophage colony-forming cells (GM-CFC) collected was 99 x 10(4)/kg per leucapheresis (range 19-800) or 260 x 10(4)/kg in total per patient (110-1800). Six patients underwent myeloablative chemotherapy with PBPC rescue. No autologous bone marrow or growth factors post-PBPC infusion were administered. The median duration of severe neutropenia (< 0.5 x 10(9)/L) was 8.5 days (range 5-10) and to recovery of neutrophils post-PBPC infusion was 11.5 days (10-15). Severe thrombocytopenia (< 20 x 10(9)/L) was present for 4 days (range 1-5) and the median number of days post-infusion to platelet-transfusion independence was 9 (6-12). In conclusion, G-CSF combined with chemotherapy mobilised large numbers of PBPC for subsequent autotransplantation in pretreated patients with NHL. A single leukapheresis procedure may be sufficient following this protocol.

We performed a retrospective analysis on 45 patients who, between January 1989 and October 1993, received VAPEC-B chemotherapy for high and intermediate grade non-Hodgkin's lymphoma. The aim was to assess response and tolerance to treatment. The weekly regimen consisted of: doxorubicin 35 mg/m2 i.v. weeks 1,3,5,7,9,11; cyclophosphamide 350 mg/m2 i.v. weeks 1, 5, 9; etoposide 100 mg/m2 p.o. daily for 5 days, weeks 3, 7, 11; vincristine 1.4 mg/m2 i.v. (2 mg max.) weeks 2, 4, 6, 8, 10; bleomycin 10 mg/m2 i.v. weeks 2, 6, 10; methotrexate 12.5 mg i.t. weeks 1, 5, 9; prednisolone 50 mg p.o. daily for 6 weeks, reduced to 25 mg daily for 6 weeks. The patients treated were aged 22-71 years, 34 (75%) had high grade (Working Formulation) non-Hodgkin's lymphoma (NHL); 11 (24%) had intermediate grade NHL; 25 had Stage III/IV disease; and 14 (31%) had marrow involvement. The majority of patients (76%) received VAPEC-B as first line chemotherapy; the remainder received it for relapsing disease. Follow-up time from completion of VAPEC-B chemotherapy ranged from 6 months to 50 months (median 25). VAPEC-B, as first line therapy, induced a complete response (CR) and partial response (PR) in 79% and 18% respectively, whilst 3% had no response to treatment. VAPEC-B used for relapsing disease produced CR and PR in 64% and 27% respectively, whilst 9% failed to respond. Six patients in PR and five patients in CR have subsequently undergone an autologous bone marrow transplant or a peripheral blood stem cell transplant. In the group who received VAPEC-B first line but did not proceed to transplant (27 patients), five relapsed (three with CNS disease who had not had CNS prophylaxis). Tolerance to treatment was measured by WHO toxicity scores. The haemoglobin (Hb) toxicity median score for all patients was grade 1 (Hb 9.5-10.9 g/dl), and the white cell count (WCC), toxicity score was grade 2 (WCC 2.0-2.9 x 10(9)/l). No platelet toxicity was observed. Ten per cent of patients suffered grade 3 severity infections requiring antibiotics and there was one treatment related death. The majority of patients received VAPEC-B on time, however, 24% patients had a 2-week delay. VAPEC-B chemotherapy is an effective regimen for malignant lymphoma, either as a first line or as a salvage treatment. Although chemotherapy was given weekly, the tolerance to treatment was acceptable, thus making this short regimen a good alternative to CHOP chemotherapy.

High-dose therapy with peripheral blood stem cell (PBSC) support is a frequently used treatment option in younger patients with poor prognosis histologically indolent (low-grade) non-Hodgkin's lymphoma (NHL), usually at the time of second or subsequent response to conventional-dose therapy. We have undertaken PBSC collection in 57 patients with histologically indolent NHL mobilized with either cyclophosphamide 1.5 g/m2 or the ESHAP regimen, followed by daily G-CSF. Progenitor cell yields were determined by quantification of CD34+ cells and GM-CFC. Twelve patients (21%) failed to achieve the minimum progenitor cell requirements of 1 x 10(6)/kg CD34+ cells or 1 x 10(5)/kg GM-CFC in their pooled harvests and 40 patients (70%) failed to achieve the optimal harvest thresholds of 3.5 x 10(6)/kg CD34+ cells or 3.5 x 10(5)/kg GM-CFC. This high failure rate is significantly higher than that in patients with histologically aggressive NHL or Hodgkin's disease. A multivariate analysis was performed to identify factors contributing to the low stem cell yields in this group. This identified the time interval from the last chemotherapy to the priming chemotherapy as the most important predictive factor. With respect to CD34 and GM-CFC numbers, on the single harvest on the day the white cell count first exceeded 5 x 10(9)/l the P values were 0.0078 and 0.0065, respectively, and for the progenitor cell values on the pooled harvests the P values were 0.004 for CD34+ cells and 0.015 for GM-CFC. Progenitor cell yields may therefore be improved in patients with low grade lymphoma by harvesting at diagnosis if no marrow disease is present, or by delaying mobilization for 6 months post-chemotherapy in patients in first or subsequent remission.

Based on the single-agent activity of both paclitaxel and cyclophosphamide in the treatment of non-Hodgkin's lymphoma (NHL), we conducted a phase II study to evaluate the efficacy of the combination of the two drugs in patients with refractory and relapsed aggressive NHL. All patients received 900 mg/m2 bolus of cyclophosphamide intravenously daily for 3 consecutive days with a concurrent infusion of 150 mg/m2 of paclitaxel over 72 h (50 mg/m2/d). 24 h after the completion of chemotherapy, patients received subcutaneous injections of 5 microg/kg of granulocyte-colony stimulating factor (G-CSF) daily until white cell count recovery. Treatment was repeated every 3 weeks. Patients who had at least a partial response (PR) after two courses continued to receive a maximum of four courses. Patients with responding disease were allowed to undergo high-dose chemotherapy followed by stem-cell/bone marrow transplantation if they were eligible. Of the 77 patients who were eligible for the study, 74 (96%) were evaluable for toxicity and treatment response. The overall response rate was 45% (95% CI 33-57%). Patients who received treatment after their disease relapsed from a complete response (CR) had an 81% response rate (38% CRs), whereas those with primary refractory disease had a 22% response rate. Toxicities of > grade 2 included alopecia (100%) and stomatitis (25%). Neutropenic fever of grade > 2 occurred after 18% of the courses, and platelet count of < or = 20 x 10(9)/l developed after 20% of the courses. Thus, the combination of paclitaxel plus high-dose cyclophosphamide is an effective new regimen in the treatment of refractory and relapsed NHL.
