Seventeen patients with recurrent or refractory non-Hodgkin's lymphoma were treated with EMVP (Etoposide 75 mg/m2 i.v. d 1-5, Methotrexate 100mg/m2 i.v. d 1, Vindesine 3 mg/body i.v. d 1, Prednisolone 60 mg/m2 p.o. d 1-5), repeating every 3 weeks. Six complete responses (35%) and five partial responses (30%) were obtained with an overall response rate of 65%. The median duration of response was 26 months (range 8-49+months) for complete response (CR) and 4 months (range 2-6 months) for partial response (PR). The median duration of survival was 31 months for CR, 11 months for PR and 10 months for all patients, respectively. The major toxic effect was myelosuppression. Leukopenia less than 1,000/mm3 and thrombocytopenia less than 25,000/mm3 occurred in 5 and 3 patients, respectively. The other toxicities were alopecia, nausea and mucositis. However, these toxicities were well tolerated and clinically manageable. These results suggested that EMVP therapy was an effective regimen for patients with recurrent or refractory lymphoma.

Results of second line chemotherapy schedules to treat refractory lymphoma have usually been poor. In this study we have treated 21 patients with advanced non-Hodgkin's lymphoma, usually heavily pretreated, with VINAP regimen. This original four drug chemotherapy combination included: Vindesine, 2 mg/m2 iv on days 1 and 2; CCNU, 40 mg/m2 oral on days 3 and 4; Cytosine arabinoside, 2.4 g/m2 iv on day 3 to 6 and methyl-Prednisolone, 80 mg/m2 on days 1 to 6. Sixteen patients (76%) showed response, including 5 (23%) who achieved a complete remission (CR). Eight patients achieved a partial remission (PR), and two patients obtained an objective response. Although the responses to VINAP regimen were dramatic and rapid in onset, usually they were of short duration except in cases of lymphosarcoma cell leukaemia. The median duration of response for patients with CR was 42 weeks and for PR 11 weeks. Toxicity was acceptable, including predictable myelosuppression, frequent mucositis and occasional polyneuritis. Neither central nervous problems nor conjunctivitis or dermatitis had been seen.

One hundred and eighteen consecutive adults with newly diagnosed intermediate and high-grade non-Hodgkin's lymphoma were treated with chemotherapy comprising Doxorubicin, Cyclophosphamide, Vincristine and Prednisolone with mid-cycle Methotrexate (MTX) and leucovorin rescue ('CHOP-M'). Intrathecal MTX was given with each treatment cycle as central nervous system (CNS) prophylaxis. 'Clinical remission' was achieved in 70/110 evaluable patients (64%), complete remission: 45/110, (41%), good partial remission: 25/110 (23%). Twenty two patients (19%) died prior to completion of therapy, 18 patients had persistent disease. Hyponatremia (< 137 mmol l-1), advanced age and hypoalbuminaemia (< 32 g l-1) correlated adversely with achievement of CR (P = 0.0007, 0.0005 and 0.04 respectively). With a minimum follow up of 41 years, 47 of the seventy patients (67%) in whom clinical remission was achieved remain well, 19 have developed recurrent disease, resulting in an actuarial projected remission duration of 70% at 8 years. Four died in CR. There has been only one isolated CNS recurrence. On univariate analysis, hypoalbuminaemia, hyponatremia and beta 2 microglobulin (> 3) correlated with unfavourable outcome in terms of duration of remission (P = 0.0009, 0.007 and 0.04 respectively). On multivariate analysis, only the serum sodium (0.002) and advanced age (0.01) were predictive for remission duration. Fifty patients (45%) are alive, the overall actuarial projected survival is thus 42% at 8 years. On univariate analysis, age, hypoalbuminaemia, hyponatraemia, liver involvement and the presence of B symptoms correlated unfavourably with survival. On multivariate analysis, hypoalbuminaemia, advanced age, hyponatraemia, male gender (aged > 50) and diffuse large cell or large cell, immunoblastic histology (Working Formulation) had an adverse effect (P = 0.003, < 0.0001, < 0.0001, 0.002, and 0.03). It was further possible, using cut-off points of 32 g l-1 and 136 mmol l-1 for albumin and sodium respectively to define prognostic categories for patients who differed significantly in terms of survival.

A retrospective analysis was performed of 117 non-Hodgkin's lymphoma (NHL) patients (72 male and 45 female, mean age 55 years) treated at NCKUH between July 1988 and December 1993. Of the 115 patients who could be classified by Ann Arbor staging system, 26 patients (22.2%) were in stage 1; 23 (19.7%) in stage 2; 29 (24.8%) in stage 3; and 37 (31.6%) in stage 4. According to the International Working Formulation, three patients (2.6%) were low grade NHL, 90 (76.9%) were intermediate, and 8 (6.8%) were high grade NHL. Histologically, diffuse large cell NHL accounted for 52.1% of cases, followed by 16.2% of cases exhibiting diffuse mixed NHL. Immunophenotype analysis was available in 95 cases, which revealed 76 (80%) cases exhibiting B-cell origin, 17 (18%) cases exhibiting diffuse mixed NHL. Immunophenotype analysis was available in 95 cases, which revealed 76 (80%) cases exhibiting B-cell origin, 17 (18%) cases exhibiting T-cell origin and 2 (2%) cases were of null cell type. All patients underwent two groups of induction chemotherapy, either CHOP (Cyclophosphamide, Epirubicin, Oncovin, and Prednisolone), or "modified" COPBLAM (Cyclophosphamide, Epirubicin, Oncovin, and Prednisolone), or "modified" COPBLAM (Cyclophosphamide, Epirubicin, Oncovin, Vinblastine, Bleomycin, Procarbazine, and Prednisolone). Seventy-two cases treated through COPBLAM and 45 cases treated through CHOP were evaluated. The response rate (RR) to COPBLAM treatment was 72.2% and was 68.9% for the CHOP group (P = 0.51). The 5-year overall survival rate (OAS) was 44.1% for COPBLAM, versus 40% for CHOP (P = 0.15). The disease-free survival (DFS) was 72.6% at 63 months for COPBLAM and 58% at 51 months for CHOP (P = 0.16). Neither B cell nor T-cell lineages of NHL showed any statistical difference in RR (P = 0.53, DFS (P = 0.58) or OAS (P = 0.97) to the different treatments. Using multiple logistic analysis, two independent factors, high LDH and advanced stage, were found to adversely affect the rate of complete remission. The application of the International Prognostic Index to our patients needs modification, which suggests the necessity of more evaluation before it can accurately be applied to all international series of NHL.

A 35-year-old man with non-Hodgkin's lymphoma (NHL) (follicular small cleaved, B cell, stage IVB) received double myeloablative chemotherapy with syngeneic peripheral blood stem cell transplantation (PBSCT). Although platelet recovery was delayed until day 29 after the second transplantation, thereafter trilineage hematopoietic reconstitution was achieved. The evaluation after PBSCT did not detect any residual tumor. The patient was in good health until day 138, when his platelet count suddenly began falling; on day 150, it had fallen to 1.5 x 10(4)/microliter, and the patient was re-admitted for treatment. The bone marrow was normocellular with a normal count and megakaryocyte structure. Other examinations, including serological tests and computed tomography of the neck, chest, abdomen, and retroperitoneum, did not indicate a recurrence of NHL or reveal the cause of thrombocytopenia. The patient's platelet-associated IgG (PAIgG) level was at 70.9 ng/10(7) platelets (normal range: 9-25 ng/10(7) platelets); a diagnosis of thrombocytopenia due to an autoimmune mechanism such as idiopathic thrombocytopenic purpura (ITP) was made. Prednisolone therapy increased the platelet count and reduced the PAIgG level. Thrombocytopenia with an ITP-like mechanism rarely occurs more than 100 days after autologous or syngeneic stem cell transplantation, and should be taken into consideration as a late complication of PBSCT.

Acquired von Willebrand syndrome (AVWS) associated with hypothyroidism is of type I, results from a decreased synthesis of factor VIII and von Willebrand factor (VWF), responds to desmopressin with normal half-life times for factor VIII and VWF parameters, and disappears after treatment with I-thyroxine. AVWS type I or III, which occurs in a minority of patients with Wilms' tumour in the complete absence of an inhibitor against VWF and no absorption of factor VIII or VWF onto nephroblastoma cells, responds to chemotherapy and/or tumour resection. Hyaluronic acid produced by nephroblastoma cells may be the causative factor in atypical AVWS in Wilms' tumour. AVWS associated with thrombocythaemia of various myeloproliferative disorders is characterized by normal factor VIII and von Willebrand factor antigen (VWF: Ag) levels and a selective deficiency of functional ristocetin co-factor activity (VWF: RCo) and collagen-binding activity (VWF: CBA). AVWS type II in thrombocythaemia is caused by a platelet-dependent proteolysis of large VWF multimers, given the inverse relationship between platelet count and large VWF multimers in plasma and specific increases in the number of proteolytic VWF fragments in plasma. The laboratory findings of AVWS associated with systemic lupus erythematosus or IgG benign monoclonal gammopathy are characterized by a prolonged bleeding time and activated partial thromboplastin time, decreased or absent ristocetin-induced platelet activity, low to very low levels of factor VIII coagulant activity (mean 15%), VWF: Ag (mean 10.7%) and VWF: RCo (mean 6.2%), and a type II multimeric pattern of VWF. Neutralizing and non-neutralizing anti-VWF autoantibodies, usually IgG, have been detected in patient plasma either free or tightly bound to the intermediate and high molecular weight VWF factor VIII particles. The bound auto antibody-antigen complex is rapidly cleared from the circulation, resulting in low levels of factor VIII, VWF parameters as documented by a poor response to desmopressin and VWF factor VIII concentrate. High-dose intravenous immunoglobulin transiently corrects the factor VIII coagulant and VWF levels, lasting for a few weeks in AVWS type II associated with systemic lupus erythematosus or IgG benign monoclonal gammopathy. Prednisolone is effective in AVWS associated with autoimmune disorder. Prednisolone and chemotherapy will not affect AVWS associated with IgG benign monoclonal gammopathy because the monoclonal IgG protein remains to act as an anti-VWF autoantibody. An absorption of VWF to malignant cells has been documented in a few patients with various lymphoproliferative disorders or adrenal carcinoma and suggested to result in a depletion of VWF. The clinical picture of AVWS associated with early-stage IgG multiple myeloma, chronic lymphocytic leukaemia or non-Hodgkin's lymphoma without a paraprotein or no detectable underlying disorder is similar to that of AVWS type II in IgG benign monoclonal gammopathy but poorly documented with regard to the underlying immune mechanism of AVWS. The mechanical destruction of large VWF multimers may be of relevance in conditions in which the shear rate of flowing blood is increased, as may occur in cases of aortic stenosis, other heart valve defects or stenosed vessels. Drug-induced AVWS has been described in association with the use of pesticides valproic acid, ciprofloxacin, griseofulvin, tetracycline, thrombolytic agents and hydroxyethyl starch.

A case is reported of lymphoplasmacytoid lymphoma (LPL) associated with a monoclonal immunoglobulin (Ig) M and cold agglutinin disease (CAD) that was successfully treated with rituximab. A 52-yr-old male was admitted with a direct antiglobulin test positive haemolytic anaemia and thrombocytopenia associated with monoclonal IgM. Bone marrow examinations disclosed the marked infiltration of medium-sized lymphoma cells with plasmacytoid differentiation that indicated non-Hodgkin's lymphoma of B-cell origin (LPL). Prednisolone and combination chemotherapy were temporarily effective for both anaemia and thrombocytopenia, although these strategies became refractory and bone marrow lymphoplasmacytosis persisted. CAD ameliorated, and the serum level of IgM decreased in association with the disappearance of lymphoma cells and clonal rearrangement of the Ig heavy chains in the bone marrow after treatment with rituximab. Rituximab played a significant role in the treatment of refractory CAD associated with LPL.

A 66-year-old woman presented with new onset generalised tonic-clonic seizures following her first dose of chemotherapy comprising Rituximab, Cyclophosphamide, Hydroxydaunorubicin, Oncovin and Prednisolone (R-CHOP) 10 days earlier for non-Hodgkin's lymphoma. On admission, computed tomography (CT) scan of the cranium showed no abnormality. The CT was repeated within 48 hours as the patient developed status epilepticus and papilledema; the repeat scan showed characteristics of posterior reversible encephalopathy syndrome (PRES). Association of rituximab with this condition was suspected as there was no recurrence of PRES after receiving two more cycles of CHOP without rituximab. Contrary to previously published case reports, this patient had a delayed clinical presentation.

Wolbachia 16S rRNA and fbpA genes were twice detected over 5 days in the blood of a patient with high fever. The patient was given fluoroquinolones and the fever resolved. Four weeks later, he was diagnosed with non-Hodgkin's lymphoma and received R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisolone) treatment resulting in complete remission. This is the first report of detection of Wolbachia genes from the blood of human patients with non-Hodgkin's lymphoma.
