A 25-year-old man was admitted to our hospital because of hematuria, anemia and thrombocytopenia. Laboratory examinations revealed an increased number of bone marrow megakaryocytes and an increased level of platelet-associated immunoglobulin G, suggesting immune thrombocytopenia. Computed tomography of the abdomen showed enlargement of the bilateral kidneys with multiple low-density areas, although neither lymphadenopathy nor hepatosplenomegaly was evident. After amelioration of the thrombocytopenia by prednisolone therapy, open renal biopsy was performed and a diagnosis of diffuse large B-cell non-Hodgkin's lymphoma was made. The patient achieved complete remission after CHOP therapy. This was thought to be a rare case of primary renal non-Hodgkin's lymphoma initially presenting as immune thrombocytopenia, which was treated successfully by chemotherapy.

Injectable gallium (Ga) nitrate, approved in the United States for the treatment of hypercalcemia of malignancy, has been known for more than 2 decades to have immunosuppressive properties. At therapeutic doses, it has few adverse effects, although high-dose infusions may result in severe nephrotoxicity, particularly in patients who are not adequately hydrated, and severe anemia. In animal models, Ga has been shown to have efficacy in the treatment of adjuvant arthritis, type 1 diabetes, experimental autoimmune encephalomyelitis, experimental pulmonary inflammation, cardiac allograft rejection, experimental autoimmune uveitis, endotoxic shock, and systemic lupus erythematosus. Clinical trials have demonstrated efficacy in Paget's disease of bone and activity against some malignancies, including epithelial ovarian carcinoma, non-squamous cell carcinoma of the cervix, bladder cancer, and non-Hodgkin's lymphoma. Other clinical trials underway include studies of sarcoidosis and rheumatoid arthritis. Future studies should be conducted not only in other autoimmune diseases, such as multiple sclerosis, but also in graft-versus-host disease, leprosy, and acquired immunodeficiency syndrome (AIDS).

CAMPATH-1H is a humanized antilymphocyte monoclonal antibody (mAb) directed against the CD52 antigen expressed on normal and malignant lymphocytes. We report the results of a multicenter phase II trial using intravenous CAMPATH-1H in previously treated patients with nonbulky non-Hodgkin's lymphoma (NHL) or minimal residual NHL. Sixteen previously treated patients with nonbulky NHL and two patients with minimal residual NHL, were treated with CAMPATH-1H. Changes in peripheral blood lymphocyte subsets were analyzed by multiparameter flow cytometric techniques in eleven patients. The 18 patients enrolled in the studies received CAMPATH-1H for a median duration of 6 weeks (range, 3 to 14 weeks), and a median cumulative dose of 470 mg (range, 180 to 1185 mg). Two of the sixteen patients with nonbulky NHL achieved a complete response (CR) and one patient achieved a partial response (PR). One of the two patients with minimal residual NHL achieved a molecular CR. Infusional complications were seen with the majority of patients but were more common with initial infusions. Significant hematologic toxicity was also observed with grade (3/4) thrombocytopenia (n=10), grade (3/4) neutropenia (n=4) and grade 3 anemia (n=3). Due to excessive infectious complications observed with the patients enrolled, the trials were terminated early. Anti-tumor activity was demonstrated in a small subset of previously treated low-grade lymphoma patients with nonbulky or minimal residual disease. Future studies evaluating the effect of different drug schedules, modes of mAb administration, and concurrent use of prophylactic antibiotics/antiviral/antifungal agents to optimize anti-tumor activity and limit infectious toxicities are planned.

Patients with malignant diseases frequently develop anemia. An alternative to blood transfusions is the application of recombinant human erythropoietin. Several nonrandomized and prospective, placebo-controlled studies have demonstrated the effect and safety of erythropoietin in patients with hematological malignancies, particularly in patients with multiple myeloma and low- to intermediate-grade non-Hodgkin's lymphoma. However, in patients with myelodysplastic syndromes, the rather low response rate of erythropoietin is overcome by the combination of erythropoietin with granulocyte colony-stimulating factor. A significant acceleration of the reconstitution of erythropoiesis has been reported in allogeneic, but not in autologous bone marrow transplantation. Especially in large open-label, multicenter studies, a statistically and clinically significant improvement in quality of life independent from chemotherapeutic response or tumor type has been demonstrated. A number of simple algorithms have been proposed using the pretreatment serum erythropoietin level, transfusion requirements, and early changes in hematological parameters.

A 2-year retrospective chart survey of 1064 patients with colorectal, breast, lung or ovarian cancer, Hodgkin's disease, or non-Hodgkin's lymphoma was conducted at 24 centres in France to determine the prevalence of anaemia (haemoglobin (Hb) levels < or = 120 g/l) and need for transfusion in patients who received non-platinum-based chemotherapy for more than three cycles or 3 months. Baseline Hb levels documented anaemia in 37.1% of patients (all tumour types). By cycle 3, the prevalence of anemia increased to 54.1% of patients and remained over 50% at cycle 4. At some time during chemotherapy 14.5% of patients were transfused. Predictive risk factors for anaemia requiring transfusion included low baseline Hb, decrease in Hb during the first month of chemotherapy, primary tumour site, prior blood transfusions and duration of chemotherapy. By early identification of patients at the highest risk of developing anaemia, interventions such as epoetin alfa can be employed to reduce or eliminate the need for transfusions.

We assessed the efficacy and safety of full-dose CHOP regimen plus granulocyte colony-stimulating factor to treat aggressive non-Hodgkin's lymphoma in elderly patients. Forty-two patients with untreated disease were included in this study, aged 70-79 years, with stage II or higher disease and a performance status of 0-3, without severe organ dysfunction. Of the 40 patients who could be evaluated 87.5% achieved complete remission, with a 4-year survival rate of 69% and a 3-year progression-free survival rate of 49%. When stratified by the International prognostic Index, the 4-year survival rate was 90.9% for the low and low-intermediate risk group and 41.3% for the high-intermediate and high risk group, whereas the 3-year progression survival rate was 87.7% and 11.3%, respectively. Grade 3 or 4 hematological toxicity was found in 31 instances of granulocytopenia (77.5%) and 7 of anemia (17.5%). Nonhematological toxicity of grade 3 or 4 included pneumonia in two patients, heart failure in one, and gastrointestinal bleeding in one. Full-dose CHOP regimen with granulocyte colony-stimulating factor support could achieve a high-dose intensity in elderly patients whose general physical condition was good and hence achieved a high complete remission rate, but the disease often recurred within 2 years. Consequently, a new therapeutic strategy needs to be established, particularly for patients with high-intermediate or high risk.

Infusional CDE (cyclophosphamide, doxorubicin, etoposide; iCDE) is one of the most effective chemotherapeutic regimen for human immunodeficiency virus (HIV)-associated non-Hodgkin's lymphoma (NHL), with a complete remission rate of 46% and a median overall survival of 8.2 months (Sparano JA, Blood 1993; 81:2810). Since the majority of HIV-associated NHL are CD20-positive we reasoned that the addition of rituximab to iCDE (R-iCDE) could also improve the poor outcome of these patients. As a first step we investigated the safety of R-iCDE in a phase I/II study. Thirty patients with aggressive HIV-associated NHL were enrolled between June 1998 and October 2000. Characteristics of 29 evaluable patients were: median age: 38 years (range 29-65 years); male sex 24/29; histology: DLCL 16 (55%), Burkitt 10 (35%), ALCL 2 (7%), unclassified 1 (3%); stage: I (35%), II (10%), III (10%), IV (45%); International Prognostic Index: 0, 1 (59%), 2 (24%), 3 (17%), 4, 5 (0); CD4 count: median 132/ mm3 (range 3-470/mm3). Patients received rituximab (375 mg/m2) in conjunction with iCDE (five or six cycles). All patients were treated with G-CSF and highly active antiretroviral therapy (HAART). Twenty-six of 29 patients received treatment as planned, while chemotherapy had to be discontinued in three patients (2 persistent thrombocytopenias, 1 cerebral hemorrhage). Grade 3 or 4 toxicity was observed as follows: neutropenia 79%, anemia 45%, thrombocytopenia 34%, bacterial infection 34%, opportunistic infection 7%, mucositis 17%. A dose reduction was necessary in 22%. Complete remission was achieved in 86% of the patients, partial remission in 4%. Ten percent had progressive disease. After a median follow-up of 9 months the median overall survival is not reached. The actuarial survival at 2 years is 80% and the actuarial progression-free survival is 79%. Four of 29 patients (14%) have died, three from NHL and one from cryptosporidiosis. These findings suggest that the combination of rituximab with iCDE in patients with HIV-associated NHL is safe and feasible and that the addition of the anti-CD20 antibody does not increase the risk for infections. The high complete remission rate also indicates a potential therapeutic benefit and warrants further randomized trials.

This study was designed to assess the efficacy and safety of substituting cisplatin with oxaliplatin in the DHAP (dexamethasone, cytarabine and cisplatin) regimen for patients with relapsed or refractory non-Hodgkin's lymphoma. Twenty-four evaluable patients with intermediate or high-grade non-Hodgkin's lymphoma were treated at 3-weekly intervals with oxaliplatin (130 mg/m2, d 1), cytarabine (2 g/m2 for two doses, d 2) and dexamethasone (40 mg, d 1-4). The median age of the patients was 58 (range 18-70). Histological subtypes were diffuse large B cell, 20; mantle cell, two; anaplastic large cell, one; and peripheral T cell, one. The overall objective response rate (RR) was 50% [95% confidence interval (CI) = 29-71%] including four complete responses and eight partial responses. RR for those patients treated at first relapse was higher than those treated at second and subsequent relapse (77% versus 29%). Grade 3 and 4 toxicity was mainly haematological: anaemia 17%, neutropenia 75% and thrombocytopenia 75%. No grade 4 non-haematological toxicity was reported. No significant renal and neurotoxicity was demonstrated. Median survival was 10.6 months. Probabilities of 1-year progression-free survival and overall survival were 47% (95% CI = 26-66%) and 50% (95% CI = 23-72%) respectively. In conclusion, dexamethasone, cytarabine and oxaliplatin (DHAX) is a novel combination in salvage therapy for relapsed or refractory non-Hodgkin's lymphoma. It has clinically significant activity with an acceptable toxicity profile. Lack of renal toxicity makes DHAX an attractive cytoreductive regimen before high-dose chemotherapy.

Due to concerns about toxicity, many elderly patients with aggressive non-Hodgkin's lymphoma (NHL) are not considered candidates for standard chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP). The cytoprotective agent amifostine has the potential to reduce toxicity when added to chemotherapy. The purpose of the current study was to examine the toxicity of CHOP combined with amifostine in elderly patients with aggressive NHL. A prospective phase II study was performed in patients aged 60 years and older. Patients with stage I/II disease received 4 cycles of CHOP followed by involved-field irradiation. Patients with stage III/IV received 6-8 cycles of CHOP. Amifostine (740 mg/m(2)) was administered as a 15-min i.v. infusion immediately before chemotherapy. Forty-one (median age 69.5 years, range 60-87) of 49 consecutive previously untreated patients, aged 60 years and older, with aggressive NHL seen in our center were included in the study. Twenty-one patients had stage I/II disease and 20 had stage III/IV disease. The patients received a total of 207 cycles of amifostine-CHOP. Infusion of amifostine caused mild to moderate transient side effects, including a drop of systolic blood pressure >20 mmHg in 54 cycles and nausea/vomiting in 36 cycles. Hematotoxicity of CHOP consisted of leukopenia grade 4 in only 15.4% of cycles. There were two cases of grade 3 anemia. No thrombocytopenia higher than grade 2 occurred. Febrile neutropenia was rare, occurring in 4.3% of cycles. One patient died after the first CHOP administration because of anthracycline-related acute cardiomyopathy (corresponding to a toxic death rate of 2.4%). The complete response rates were 85 and 75% in stage I/II and stage III/IV patients, respectively. After median follow-up of 33 months (range 17-50 months) the median overall survival was not reached in patients with stage I/II and was found to be 32 months in patients with stage III/IV. At 2 years, 76% of patients with stage I/II and 70% with stage III/IV were alive. Twelve of the 15 patients who died were aged older than 70. Amifostine pre-treatment was associated with a low toxicity of CHOP in elderly patients with aggressive NHL treated with curative intent. Treatment outcomes appeared not to be impaired by the addition of amifostine to CHOP. This schedule merits further testing in a randomized trial.

Anemia is a predominant clinical problem in the management of patients with non-Hodgkin's lymphoma and often an indication to initiate chemotherapy. However, many elderly patients, especially those with concomitant disorders, do not tolerate such therapy very well. This report describes three patients with low-grade non-Hodgkin's lymphoma who were treated solely with recombinant human erythropoietin (rhEPO) for lymphoma-associated anemia. The rhEPO was given at an initial dose of 150 U/kg three times weekly, with dose reduction when a response had been achieved. All three patients normalized their hemoglobin level and severe anemia-related symptoms disappeared. Responses are ongoing in two patients after 10 and 12 mo of therapy, respectively. The third patient maintained a response to rhEPO for over 5 yr, without any need for further therapeutic interventions, before dying of an unrelated event. This treatment strategy seems worthy of further investigation in selected lymphoma patients where anemia is the major complication of the disease.
