Interferon-alpha as maintenance therapy in patients with multiple myeloma.

BACKGROUND: The effect of interferon-alpha 2b (IFN-alpha-2b) on progression-free and overall survival as well as quality of life (QoL) was studied in mainly elderly patients with multiple myeloma (MM), who reached a plateau phase after melphalan/prednisone induction. PATIENTS AND METHODS: In an open phase III trial, 262 patients, median age 69 years (range 34-91), received at least 10 monthly courses of melphalan/prednisone followed by response evaluation. Plateau phase was reached by 128 patients. Next, 90 patients were randomized between IFN-alpha-2b and no maintenance therapy. Reasons for non-randomization were: refusal (18), concomitant disease (nine), protocol violation (six), WHO performance status >2 (four) and allogeneic transplantation (one) RESULTS: At a median follow-up from diagnosis of 97 months (0-140) for those patients alive, IFN-alpha-2b therapy was associated with improved progression-free survival (median 13.5 versus 8.4 months from randomization), although this did not translate in a better overall survival (41 versus 38.4 months). One-third of patients discontinued IFN-alpha due to toxicity. No differences were observed between patient groups in QoL. CONCLUSIONS: IFN maintenance therapy in MM prolongs progression-free survival and, provided that the burden of toxicity is not too high, does not adversely affect QoL.

Treatment of elderly patients with intermediate- and high-grade non-Hodgkin's lymphoma: a retrospective population-based study.

PURPOSE AND METHODS: Nowadays more people are becoming older. The median age of a patient with non-Hodgkin's lymphoma (NHL) at diagnosis is over 60 years. The incidence of NHL in elderly has increased in the last decades. Therefore, in the future, NHL will be diagnosed more often in the elderly. Data of all patients in the south-east of the Netherlands with newly diagnosed NHL between January 1991 and January 1995 were analysed in a retrospective multicentre population-based study to investigate if and how elderly patients (> 60 years) with advanced NHL (Ann Arbor Staging > or = IIB) of intermediate- and high-grade malignancy were treated. Treatment modalities applied, outcome, and causes of death were evaluated. Treatment was considered inadequate if it deviated from the standard anthracycline-containing chemotherapy (CNOP/CHOP) for a minimum of six cycles. RESULTS: The entry criteria were met by 68 patients. Of these patients, 57 (83.8%) were treated and 11 (16.2%) were not treated. The treatment consisted of CHOP (36 patients), CNOP (6 patients), chlorambucil (13 patients), or COP (2 patients). Forty-two of 68 patients had adequate treatment, but 14 of 42 (33.3%) patients had a suboptimal numbers of cycles (< 6). Of 28 patients with adequate chemotherapy, only 16 had the optimal number of cycles and dose; the result is that the treatment of 76.5% (52/68) of patients differed from that of their younger counterparts. The most important reason for treatment not being optimal was high age (23%) or poor performance (35%). In the appropriately treated patients, 62.5% (10/16) had a complete response. Survival in the CHOP/CNOP-treated group was better than in other groups. The main cause of death in the total study group was NHL. The results cannot be explained by the different international prognostic index. CONCLUSION: A significant subset (76.5%) of elderly people with intermediate/high-grade NHL received suboptimal therapy, mainly because of a suboptimal performance status. However, a significant part of the patients (23%) were not treated optimally because of high age, despite a good performance. For improving the overall survival in the elderly, it is not only the schedule that is important, but also the intention to treat the elderly patient.

Clinical and immunological evaluation of primary splenic irradiation in chronic lymphocytic leukemia: a study of 24 cases.

Little is known about the effects of primary splenic irradiation (SI) in B-cell chronic lymphocytic leukemia (B-CLL) on subpopulations of lymphocytes, immunoglobulins, and the induction of autoantibodies against erythrocytes and platelets. Twenty-four untreated patients with B-CLL were studied prospectively. One patient was excluded from analysis because of intercurrent death. Of the remaining 23 patients, 7 were female and 16 were male, with an average age of 68.4 and 61.2 years, respectively. Treatment consisted of a weekly dose of I Gy up to a total dose of 10 Gy to the spleen. Standardized evaluation was done 2 weeks before and 6 weeks after SI. Twenty patients completed the course of SI. In 14 patients there was a partial response and in 9 patients the disease remained stable. The number of leukocytes decreased rapidly and significantly, with a decrease in the fraction of lymphocytes and an increase in the neutrophil count (all P<0.0001). There was a significant increase in platelet count, but not in hemoglobin level. Nausea, slight diarrhea, pleuropneumonia, granulopenia with fever (all n=1), urinary tract infection and high fever (n=1), and thrombocytopenia occurred (n=2). One patient received transfusion of packed cells because of upper digestive tract bleeding for which cessation of SI was not necessary. The number of malignant cells showed a significant decrease (P<0.01). No significant changes in CD4/CD8 ratio were found. The number of CD4+ and CD8+-cells, however, decreased significantly (P<0.01 and 0.03, respectively). DAT remained unchanged in most (93%) and tests for antibodies to platelets in 83% of the patients. No significant changes in immunoglobin levels were observed.

The effect of optimal treatment on elderly patients with aggressive non-Hodgkin's lymphoma: more patients treated with unaffected response rates.

A substantial part of elderly patients (with good performance) with intermediate or high-grade non-Hodgkin's lymphoma (NHL) are not treated with the standard chemotherapy of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). If NHL patients are not treated with CHOP, the outcome is inferior. By adding granulocyte colony-stimulating factor (G-CSF) to CHOP chemotherapy, we aimed at treating more patients with less toxicity. We performed a multicenter population-based study (in the southeast of the Netherlands) in which elderly patients (> or = 60 years) with intermediate or high-grade stage > or = IIB NHL were treated with CHOP chemotherapy and growth factor G-CSF to increase the number of patients treated according to standard protocols. We also evaluated elderly NHL patients who were not treated with CHOP chemotherapy. Adequate therapy was defined as > or = six cycles or a total of five cycles when complete remission was achieved after three cycles. Seventy-nine NHL patients fulfilled the selection criteria. The patients were treated with CHOP plus G-CSF (n=46), CHOP (n=19), cyclophosphamide, vincristine, and prednisone (COP) (n=2), chlorambucil and prednisone (n=2), or prednisone (n=1). Nine patients were not treated with chemotherapy. The median age was 72 years (60-87). Of the 79 NHL patients, 65 were treated with CHOP chemotherapy (82%); 38 of 65 patients (59%) were adequately treated. The complete remission rate in the NHL group treated with CHOP was 65% (42 of 65 patients). The overall 3-year survival was 50%. Most of the patients died from progressive NHL (53% in the CHOP and 77% in the group not treated with CHOP). The treatment-related mortality was 15% in the CHOP group. The most important reason for not treating patients with CHOP (with or without G-CSF) was poor performance (WHO > or = 2). A significant subset of patients can be treated with CHOP chemotherapy with acceptable toxicity. The combination of CHOP plus G-CSF increased the absolute number of treatable elderly patients, resulting in more (absolute) patients with complete remission and overall survival compared to our previous study.

Paraneoplastic pemphigus as the initial presentation of chronic lymphocytic leukemia.

The case history of a 61-year-old male patient is described, who presented with severe stomatitis, conjunctivitis and leukocytosis. The diagnosis chronic lymphocytic leukemia (CLL) stage A (0) was made, for which no treatment was necessary. Progression of stomatitis and conjunctivitis and erythosquamous skin lesions with bullae and vesiculae formation developed. Under the diagnosis of bullous pemphigoid the patient was treated with corticosteroids. The histologic and immunofluorescence examination of a skin biopsy was compatible with this diagnosis, and antibodies to skin could not be detected in a first serum sample. Pseudomonas was cultured from all lesions, the corticosteroids were stopped and antibiotic treatment was started, without clear effect. Because of progression of skin lesions and debilitation, the patient finally declined all treatment and died five weeks after admission. Post-mortem examination showed enlarged lymphnodes in the cervical, aortal en iliacal areas, with histology confirming the diagnosis of CLL. Indirect immunofluorescence with the second serum sample showed auto-antibodies in high titer directed against the intercellular epithelial substance. Immunoblot studies showed binding with the classic target antigens in paraneoplastic pemphigus. Re-examination of the histologic skin specimen and the result of direct immunofluorescence were in retrospect compatible with the diagnosis of paraneoplastic pemphigus.

Adjuvant chemo-hormonal therapy with cyclophosphamide, doxorubicin and 5-fluorouracil (CAF) with or without medroxyprogesterone acetate (MPA) for node-positive cancer patients, update at 12 years follow up.

An update with 10 years of follow up of a study adding adjuvant MPA to CAF chemotherapy is presented. A total of 409 patients were entered, of which 200 were randomized to receive 500 mg of MPA i.m. on days 1-28 and twice per week thereafter for 6 months. There was a significant improvement in metastases-free and overall survival in women >60 years of age receiving MPA (P=0.01 and P=0.02 respectively). A detrimental effect of MPA was seen in women <40 years. Possible reasons for these results are discussed.

An unwanted side effect of hydroxyurea in a patient with idiopathic myelofibrosis.

A patient with idiopathic myelofibrosis is reported who developed a drug fever after treatment with hydroxyurea, a generally effective and well-tolerated drug in chronic myeloproliferative syndromes. Typically, this form of fever develops after a few weeks of exposure to the drug and disappears with discontinuation of the drug. Possible interactions with prostaglandin or leukotriene metabolism may play a role.

[Combination of 5-FU, high dose methotrexate, epirubicin and cisplatin (FEMTX-P protocol) in non surgical or locally recurrent metastatic gastric cancers].

In this phase II study, fifty patients with unresectable locally advanced and/or metastatic gastric carcinoma were treated with methotrexate 1.5 g/m2 iv and 5-fluorouracil 1.5 g/m2 iv on day 1; leucovorin rescue 15 mg/m2 orally every 6 h for 8 doses on day 2 and 3; epirubicin 60 mg/m2 iv and cisplatin 50 mg/m2 iv on day 15, q 4 weeks. The median age of the patients was 59 years and their median performance status 1. In forty-eight patients evaluable for response, five (10.4%) of the patients achieved a complete response and seventeen (35.6%) obtained a partial response (total response rate 46%; 95% confidence interval: 32%-60%). The median duration of response was 8+ months (range: 5-25 months). The median duration of survival of all patients was 10 months (range: 1-25+ months). Toxicities > grade 2 included vomiting grade 3 (31%), leucopenia grade 4 (18%) and thrombocytopenia grade 4 (4%). Treatment postponement or dose reduction for hematologic toxicity was necessary in 54% of patients. Median survival was 10 months. In conclusion, the FEMTX-P regimen is an active treatment in advanced gastric carcinoma with acceptable toxicity.

Malignant lymphoma of the testis.

Five patients with primary non-Hodgkin's lymphoma of the testis were studied. The lymphomas had an intermediate grade of malignancy according to the Working Formulation. One patient was in clinical stage IEA, 3 in clinical stage IIEA and one in clinical stage IVB. Central nervous system (CNS) infiltration occurred in 3 patients. The survival was very poor and ranged from 9 days to 5 1/2 years after diagnosis, median 7 1/2 months. In order to improve prognosis aggressive (3 or more cytostatics) chemotherapy is recommended to follow orchidectomy and staging. As for other lymphomas of intermediate- and high-grade malignancy, a more effective systemic therapy is needed for the younger patients, but in the elderly (greater than 70 years) the regimen and the dose intensity have to be adapted to their tolerance. Prophylactic radiation of the opposite uninvolved testis is not recommended, but frequent scrotal ultrasonography during the first 2 years after diagnosis appears essential. Prophylactic intrathecal chemotherapy means an overtreatment for patients in clinical stages I and II, but is indicated in relapsing patients and in clinical stages III and IV.

Measurements of serum ferritin used to predict concentrations of iron in bone marrow in anemia of chronic disease.

We determined serum ferritin, C-reactive protein (CRP), fibrinogen, and the erythrocyte sedimentation rate (ESR) in 73 patients with anemia of chronic disease. Nomograms of CRP, ESR, or fibrinogen vs ferritin concentrations were constructed and used to estimate the iron store in bone marrow. Iron stores estimated from the nomograms were compared with the results of staining cytological bone marrow smears for iron, the reference method for evaluating iron in bone marrow. In contrast to the results of Witte et al. (Clin Chem 1985;31:1011; Am J Clin Pathol 1986;85:202-6 and 1988;90:85-7), we observed that nomograms of CRP, fibrinogen, or ESR (i.e., acute-phase reactants not influenced by changes in iron metabolism) vs ferritin are not suitable to correct for the acute-phase component of changes in ferritin concentrations. For ferritin concentrations less than 70 micrograms/L, we found that iron deficiency, as judged from bone marrow iron stain, apparently was always present.
