Nowadays, maintenance dialysis can be proposed to patients suffering from myeloma with end-stage chronic renal failure. We report here data from eight patients dialysed either by hemo- (6) or peritoneal dialysis (2), together with chemotherapy in half of them. Six patients died; the longest survival has been about 6 years. The main cause of morbidity was sepsis, especially in peritoneal dialysis patients; therefore we now favour hemodialysis in patients exposed to aggressive chemotherapy. We think dialysis justified in all cases, including those with high tumor mass, in order to expect the effect of chemotherapy; then, provided good response to drugs, further survival can be consistently improved. Once on maintenance dialysis, main drawbacks for these patients are cardiovascular complications (AL amyloidosis) and above all anemia; the latter however can be markedly improved, thanks to erythropoietin therapy which provides these patients with much better quality of life.

We designed an oral equivalent regime to mimic VAD and its hybrids, using idarubicin and dexamethasone (Z-Dex) given in four cycles to induce cytoreduction prior to dose intensification in multiple myeloma cases. 20 patients (de novo n = 15, replaced VAD n = 2, relapsed n = 2, and resistant n = 1), 13 males and seven females with a median age of 54 years (range 40-65 years) received Z-Dex therapy. The overall response rate was 70% (14/20), with one patient (5%) achieving complete remission (CR). The response rate for previously untreated patients was 80% (12/15), with a CR rate of 6.7% (1/15). Both patients who received Z-Dex in place of VAD continued to respond. Myelosuppression was seen in 14/20 patients (70%); 4/20 (20%) developing severe neutropenia with one death from neutropenic sepsis. Gastrointestinal toxicity and alopecia were infrequently reported. Satisfactory responses can be obtained using an oral regime equivalent to VAD with tolerable toxicity and morbidity.

Thirty-one patients (median age, 44 years) with advanced hematologic malignancies were given thiotepa 15 mg/kg, and cyclophosphamide 120 (n = 14) or 150 (n = 17) mg/kg followed by unfractionated peripheral blood stem cell transplants (PBSCT) from genotypically identical siblings (n = 28) or one antigen mismatched family donor (n = 3). Donors were mobilized with granulocyte colony-stimulating factor 5 to 10 microgram/kg/d for 6 days and underwent two to three leukapheresis on days +5, +6, +7. The median cell yield per donor expressed/kg of recipients body weight was as follows: nucleated cells 13 x 10(8)/kg; CD34+ cells 6 x 10(6)/kg; colony-forming unit-granulocyte macrophage 38 x 10(4)/kg, and CD3+ cells 449 x 10(6)/kg. The diagnoses were chronic myeloid leukemia (n = 4), acute myeloid (n = 9) or lymphoid leukemia (n = 2), acute myelofibrosis (n = 2), multiple myeloma (n = 1), lymphoma (n = 6), chronic lymphocytic leukemia (n = 1) myelodysplasia (n = 6). Twenty-eight patients had advanced disease, 29 patients were first grafts, and 2 were second transplants 3 and 9 years after the first. Neutrophil counts of 0.5 x 10(9)/L and platelet counts of 30 x 10(9)/L platelets were both achieved on day +14 (median). Engraftment could be proven by sex markers or DNA polymorphism in 29 of 31 patients: one had early leukemia relapse and one patient was unevaluable because of early death. Acute graft-versus-host disease (GVHD) was scored as minimal or absent (grade 0 to 1) in 14 patients, moderate (grade II) in 13, and severe (grade III to IV) in four. Causes of death were leukemia (n = 4), acute GVHD (n = 4, with associated cytomegalovirus infections in three), sepsis (n = 1), liver failure (n = 1), multiorgan failure (n = 1), and hemorrhage (n = 1). The actuarial transplant mortality is 29%, the actuarial relapse rate 22%. Nineteen patients survive with a median follow up of 288 days (100-690). The actuarial 2-year survival is 57%. Three patients received PBSCT from family donors mismatched for one class II antigen: all engrafted, one developed grade I aGVHD; one died of leukemia on day +155; two are alive disease free 267 to 290 days postgraft. This study suggests that thiotepa cyclophosphamide followed by unfractionated PBSC allograft may be an alternative form of transplant for adults with advanced leukemia, also in the setting of one antigen mismatched donor. The engraftment is rapid with acceptable GVHD and relatively low transplant-related mortality.

In order to clarify the clinical usefulness of the morphological classification of multiple myeloma (MM) originally proposed by Greipp, et al. and modified by us, Giemsa-stained MM cells in bone marrows obtained from 61 untreated patients were analyzed. According to the original classification, there was no significant difference in survival time between the patients with plasmablastic MM and those with other types. However, the mean survival time of each type of MM according to the modified classification was 2014 days in mature MM, 1564 days in intermediate MM, 967 days in immature MM, and 254 days in plasmablastic MM. The survival time of plasmablastic MM was significantly shorter than those of other types. DNA aneuploidy was observed more frequently in plasmablastic MM than in other types. Furthermore, PCNA- and Ki-67-positive rates were higher in plasmablastic MM than in other ones. Four of five patients with plasmablastic MM who were treated with VAD(vincristine, doxorubicin, dexamethasone) regimen showed no significant effect, and most patients with the type died of sepsis or renal failure. From these results, it was concluded that patients with plasmablastic MM have a poor prognosis. Moreover, our modified classification is recommended as a clinically useful approach for selecting treatment strategy and predicting an accurate prognosis.

We evaluated toxicities and responses to a novel, dose intensive and time sequenced, chemotherapy programme (DC-IE) in 45 patients with high-risk myeloma. DC-IE consisted of: dexamethasone (days 1-4); cyclophosphamide (day 5); idarubicin and etoposide (days 8-10). Complete response (CR) was achieved in four patients, six patients achieved near complete responses (nCR) and 21 patients achieved a partial remission (PR). Overall response rate was 76% (CI 56-94%) for newly diagnosed patients (n = 21) and 62% (CI 36-81%) for relapsed/refractory patients (n = 24). Toxicities were limited to myelosuppression; two patients died of sepsis during neutropenia (4%). DC-IE is active and tolerable for high-risk multiple myeloma, including patients with relapsed or refractory disease to anthracycline containing regimens.

A 74-year-old man with multiple myeloma developed facial and cervical cellulitis and severe sepsis as a complication of surgery (alar region basal cell carcinoma). The etiological agent was, surprisingly, penicillin-resistant Streptococcus pneumoniae (PRSP). The patient successfully received 16 days of antibiotics. Amoxicillin was given as monotherapy during the last 14 days of treatment. PRSP can be responsible not only for otitis media, pneumonia or meningitis, but also for various other types of infection in patients with predisposing factors.

The incidence of documented infections after autologous peripheral blood progenitor cells transplantation (PBPCT) was retrospectively evaluated in 86 consecutive patients (47 males 39 females; median age 36 years, range, 18-63) treated in our institution; 83 patients had refractory hematological malignancies (40 non-Hodgkin's lymphoma, 19 Hodgkin's disease, 17 multiple myeloma, 7 acute myeloblastic leukemia) and 3 had solid tumors (1 rabdomyosarcoma, 1 neuroblastoma, 1 osteosarcoma). All patients developed fever after transplantation lasting a median of 2 days (range 1-17); 20 instances of documented sepsis developed in 17 patients (19.7%). Gram positive microorganisms were implicated in all but 4 cases. There were no fatalities directly due to infections and no correlation was found between the risk of infection and reaching PMN > 0, 1 x 10(9)/L, PMN > 0.5 x 10(9)/L. In addition no specific risk factors related to age, disease, conditioning regimen, use of central venous catheter (CVC), type of transplant, and isolation measures were identified.

Renal involvement remains a major complication of multiple myeloma, particularly in advanced disease. A retrospective analysis was performed of the modes of presentation, treatment and outcome of all patients with multiple myeloma treated in our renal unit between 1987 and 1996. Thirty-four patients were identified: in 26 (76%) the diagnosis of myeloma was made only after referral. Light chains were the most common paraprotein in both serum and urine. Twenty-one (62%) patients underwent renal biopsy: myeloma cast nephropathy was the predominant histological finding in 16 cases. Thirty-one (91%) patients had severe renal failure (GFR < 20 mL/min), with 28 (82%) requiring dialysis within 2 weeks of admission. Despite treatment of presumed precipitaing causes of acute deterioration in renal function, only 1 of these 28 patients subsequently became independent of dialysis. Most had advanced stage myeloma: 29 (85%) were Durie-Salmon stage II or III. Hypercalcemia, sepsis and pathological fractures were the principal complications. Median survival overall was 5 months. The main causes of death were withdrawal of renal replacement therapy (overwhelming myeloma, severe debilitation) and sepsis. Nineteen (56%) patients received long-term (> 1 month) renal replacement therapy with a median survival of 8 months. However, five of these (26%) have survived for more than 12 months on dialysis and report a good quality of life.

The use of autologous stem cell transplantation (ASCT) for the treatment of multiple myeloma is increasing. Anticoagulation may be required during ASCT for conditions such as Hickman line thrombosis. The safety of anticoagulation in patients receiving ASCT is unknown. We report a retrospective case-control study of the safety of therapeutic anticoagulation in patients with multiple myeloma receiving ASCT. We identified 10 patients who received therapeutic anticoagulation during ASCT. For each of the 10 cases identified, two matched controls were selected. As a primary endpoint, bleeding complications were assessed. Secondary endpoints included survival, length of hospital stay, transfusion requirements, grade 4 toxicity, and days to platelet engraftment. Bleeding complications were not significantly different between patients receiving anticoagulation and controls (P = 0.3). Three of 10 anticoagulated patients and two of 20 controls had a bleeding complication. Mortality during admission was similar (P = 1.0); one anticoagulated patient and one control died of sepsis. A trend towards increased median number of platelet transfusions in the heparinized patients was seen (27 vs 12 units, P = 0.055), reflecting the higher transfusion threshold chosen for the anticoagulated patients. The other secondary endpoints did not differ between patients and controls. In this case control study, bleeding was not significantly increased in the group receiving anticoagulation during ASCT. This group electively received more units of platelets than controls. Thus, therapeutic anticoagulation can be managed with minimal increased toxicity during ASCT.
