Etoposide produces reversible inhibition of topoisomerase II, leading to cleavage of DNA, and thereby has an antitumor effect. This mechanism suggests that the longer treatment is continued, the greater the antitumor effect will be. In the present study, both therapeutic and adverse effects of long-term treatment with low-dose oral etoposide were studied in 29 patients aged > or = 65 years with non-Hodgkin's lymphoma (NHL) for whom standard chemotherapy was not effective or refractory. These patients received etoposide at a dose of 50 mg/d for as long as possible. Treatment was continued until white blood cell count decreased to < or = 2,000/microL or the platelet count decreased to < or = 5 x 10(4)/microL. According to the World Health Organization (WHO) criteria of therapeutic effects, 6 (20.7%) of the 29 patients achieved complete remission and 13 patients (44.8%) had partial remission, for a response rate of 65.5%. Adverse effects of > or = grade 3 included leukopenia in 24 patients (82.8%) and anemia in 7 (24.1%). Granulocyte colony-stimulating factor (G-CSF) was given in combination with etoposide to eight patients because of leukopenia (granulocyte count < or = 1,000/microL). In view of the excellent subjective tolerance, low incidence of serious adverse effects, and good activity, single agent oral etoposide given continuously over prolonged periods represents a useful treatment for elderly patients with NHL.

Fludarabine is an antineoplastic agent which has been studied in patients with a variety of lymphoproliferative malignancies. Clinical evidence from comparative studies in chronic lymphocytic leukaemia (CLL) suggests that fludarabine is at least as effective as CAP (cyclophosphamide, doxorubicin and prednisone) or CHOP (cyclophosphamide, vincristine, doxorubicin and prednisone) in previously treated or chemotherapy-naive patients and significantly more effective than chlorambucil in terms of response rate and duration and survival in chemotherapy-naive patients. Promising results have also been reported with fludarabine-based combination therapy in the treatment of patients with CLL. In addition, sequential therapy with fludarabine and cytarabine has demonstrated good efficacy in the treatment of acute leukaemias, as has fludarabine monotherapy and combination therapy in low grade non-Hodgkin's lymphoma. A favourable cytoreductive response has been reported in patients with lymphoplasmacytoid lymphoma and in a smaller number of patients with cutaneous T cell lymphomas, CLL of T cell origin or prolymphocytic leukaemia. Recent data also support the use of fludarabine, either as a component of a nonmyeloablative conditioning regimen or in the attainment of minimal residual disease, in patients undergoing peripheral blood stem cell or bone marrow transplantation. The tolerability profile of fludarabine is similar to that of CAP, with the most common adverse events being granulocytopenia, thrombocytopenia, anaemia and infection. Alopecia and nausea/vomiting appear to be less frequent with fludarabine therapy than with CAP although the development of immune cytopenias is more frequent with fludarabine. Severe neurotoxicity has been reported with fludarabine but this is mostly confined to the use of high doses. Clinical experience therefore indicates that fludarabine is an effective and generally well-tolerated antineoplastic agent for the second-line treatment of advanced CLL. Recent data from comparative studies also support the earlier use of fludarabine in the treatment of chemotherapy-naive patients with CLL. Furthermore, results of available studies are increasingly highlighting an important future role for fludarabine in the treatment of acute leukaemias and low grade NHL and possibly other lymphoproliferative disorders, particularly when used as a component of combination chemotherapy.

Autoimmune hemolytic anemia (AIHA) complicated with non-Hodgkin's lymphoma (NHL) is not unusual. Two cases of NHL associated with cold agglutinin disease were reported. Case 1: A 38-year-old man had diffuse medium-sized cell NHL diagnosed by cervical lymph node biopsy. The Hb was 7.6 g/dl with a cold agglutinin titer of 32,768, and the IgM level was 890 mg/dl (I-specific), so cold agglutinin disease (CAD) was suspected. After administration of COP-BLAM therapy, complete remission (CR) was achieved along with a decrease in the cold agglutinin titer and improvement of anemia. Case 2: A 68-year-old woman had follicular mixed NHL diagnosed by inguinal lymph node biopsy. The Hb was 8.2 g/dl with a cold agglutinin titer of 51,200, and an IgM level of 920 mg/dl (I specific), thus concurrent CAD was suspected. Biweekly COP-BLAM therapy was administered and CR was achieved along with a decrease in the cold agglutinin titer and improvement of her anemia. In both patients, the cold agglutinin titer decreased after CR was achieved suggesting that production of anti-erythrocyte autoantibody was due to disturbance of the antibody system by NHL.

THP-COPBLM including pirarubicin (THP), which is thought to be less toxic than doxorubicin, was used to treat non-Hodgkin's lymphoma (NHL) and the remission rate and adverse effects were studied in 26 patients older than 70 years. Complete remission (CR) was achieved in 19 patients (73.1%) and partial remission in three (11.5%). Classified by stages, CR was achieved in seven out of nine stage II patients and 12 out of 17 stage III, IV patients. The 2-year survival rate was 60.3%. Grade 3 or higher adverse effects included leukopenia in eight patients (30.8%), anemia in three (11.5%), thrombocytopenia in two (7.7%) and nausea/vomiting in 1 (3.8%). The THP-COPBLM regimen appears useful for the treatment of NHL in elderly patients. The regimen was seldom associated with gastrointestinal symptoms and cardiotoxicity. Despite the administration of granulocyte colony-stimulating factor (G-CSF), however, the white blood cell count decreased in many patients, suggesting the necessity for further study of this regimen to modify the dose of THP.

Patients with refractory or relapsed non-Hodgkin's lymphoma (NHL), acute T-cell leukemia (ATL), ATL lymphoma and acute lymphocytic leukemia (ALL) received EPOCH therapy. All were previously treated with doxorubicin (DOX), vincristine (VCR) and other drugs. The EPOCH treatment schedule is consisted with DOX (10 mg/M2/day, 5 days c.i.v.), VCR (0.4 mg/M2/day, 4 days c.i.v.), etoposide (50 mg/M2/day, 4 days c.i.v.), cyclophosphamide (750 mg/M2/day, day 6 i.v.) and prednisolone (60 mg/M2/day, 5 days p.o.). Twenty-one patients (ALL:10, NHL:8, ATLL:2, ATL:1) were assessable for response and toxicity. Two patients with ALL and NHL, respectively, achieved a complete remission and 3 patients obtained partial remission (NHL:2, ATLL:1). The hematological toxicity (grade > 1) included neutoropenia, anemia and thrombocytopenia, which were observed in 83.3%, 76.7% and 76.7% respectively, of total 30 EPOCH courses. The major non-hematological toxicities were nausea/vomiting, constipation and infection, but most of the toxicity were tolerable with sufficient clinical supportive care. These results indicate that continuous infusion of DOX, VCR and ETP might be effective in patients who were treated with, and presumed to be resistant to the same drugs administrated by bolus infusion.

A 47-year-old male patient was admitted because of anemia. He had been diagnosed as non-Hodgkin's lymphoma (Follicular mixed, B cell type, stage ISA) by splenectomy two years before. Bone marrow examination on admission revealed lymphoma cell infiltration and marked decrease in erythroid cells. These findings confirmed relapsed lymphoma with acquired pure red cell aplasia. After several courses of combination chemotherapy, lymphoma cells disappeared from bone marrow, but PRCA was not improved. In this case there were two times remission of PRCA. At first time, acute B type hepatitis occurred during the chemotherapy, anemia improved transiently. At the second time, mild acute hepatitis associated with herpes zoster occurred. Twenty days after hepatic injury, PRCA was improved, and continued in remission state till present day. To disclose the mechanism of PRCA in this case, erythroid colony assay of marrow cells was performed. This showed the presence of inhibitory factor in patient's serum at PRCA state, that was considered to be related to the occurrence of PRCA. These findings suggest that the improvement of PRCA was associated with the changes on immunological condition after acute hepatitis in this case.

Anemia is a frequent complication in hematologic malignancies. In advanced stages of chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and myeloma, anemia usually develops in parallel with marrow involvement. However, anemia may occur in the absence of overt infiltration of bone marrow by malignant cells. When all other causes of anemia (such as chronic bleeding, vitamin deficiency, hemolysis, and pure red blood cell aplasia) are eliminated, anemia can be related to "anemia of chronic disorders." Myelodysplastic syndromes are characterized by cytopenias. Anemia is very frequent, and nearly 90% of patients present with anemia during the evolution of the disease. In this disorder, erythroid progenitors are defective for their proliferation and maturation, as shown by in vitro culture techniques. Moreover, these patients often have a high endogenous serum erythropoietin level. The rationale for treating these patients with epoetin alfa is the possibility of overcoming the defective proliferation by pharmacologic doses of epoetin alfa. The response rate was rather low with epoetin alfa alone. Combinations with earlier-acting cytokines, such as recombinant human granulocyte colony-stimulating factor, have been tested in an attempt to improve response rates.

Recombinant human erythropoietin has been recently introduced as an important alternative for treatment of anaemia in multiple myeloma and non-Hodgkin's lymphoma. In the present paper we review the basis for its use in the anaemia of both entities, and the most relevant clinical trials showing the effect of erythropoietin. In MM patients the response rate (assessed by an increase of at least 2g/dl in the Hb level) ranges between 60%-80% while in NHL patients it ranges from 50% to 61%. The most appropriate EPO dose is around 5000 units per day, which is equivalent to 150 u/kg, three times per week. In addition, this review provides tools to decide the best candidates for this treatment and a guideline to monitor its efficacy.

Irradiation is known to cause temporary to permanent marrow aplasia in cancer patients when administered as a sole therapy or in combination with chemotherapy. Until now, no studies have been carried out evaluating the haematological toxicities of involved field radiation administered post autologous stem cell transplantation (ASCT). We assessed bone marrow (BM) toxicity in 93 patients who received involved field radiation post ASCT (non-Hodgkin's lymphoma 21, Hodgkin's disease 7, breast cancer 15, and other solid tumours 50. Severe BM toxicity, with grade IV neutropenia, and/or thrombocytopenia, and/or anaemia necessitating interruption of radiotherapy for more than a week, was observed in 11 patients (malignant lymphoma-8 of which 7 were NHL, and 1 HD, breast cancer-1, Wilm's tumour-1, Ewing's sarcoma-1). Patients with malignant lymphoma were at higher risk of developing post ASCT radiation-induced cytopenias than patients with breast cancer or solid tumours, 28% vs 4.5%, respectively (P < 0.05). Of the 11 patients, 7 developed bacterial sepsis and 10 were hospitalised. The radiation-induced cytopenia patients necessitated platelets and red blood cell transfusions, interrupting the course of irradiation. Of the patients suffering from non-Hodgkin's lymphoma, 8/14 (57%) of those who received conventional courses of radiotherapy relapsed compared to 6/7 (86%) of those who received interrupted radiotherapy (P < 0.05). The most appropriate timing for radiation in malignant lymphoma patients who are scheduled for ASCT, as well as the protective role of haematopoietic growth factors like erythropoietin and Granulocyte (G) or Granulocyte-Monocyte (GM), colony stimulating factors (CSF) and others, are discussed.

A 72-year-old woman was admitted to our hospital because of fever, anemia and thrombocytopenia in March 1997. Laboratory findings showed elevated serum LDH levels and polyclonal gammopathy. Bone marrow aspiration samples revealed hemophagocytosis and plasmacytosis. Although serum interleukin-6 was elevated, serum interferon-lambda and tumor necrosis factor-alpha were below detectable limits. Magnetic resonance images disclosed a tumor in the patient's pelvic cavity. The tumor was resected and diagnosed as non-Hodgkin's lymphoma. The patient was treated with combination chemotherapy and has remained in complete remission. Also, histiocyte and plasma cell counts in the bone marrow fell significantly and the serum interleukin-6 level returned to the normal range. We reasoned that lymphoma cells may have induced plasmacytosis in the bone marrow and polyclonal gammopathy accompanied by hemophagocytic syndrome.
