The effect of interferon on the health-related quality of life in multiple myeloma was assessed in two trials carried out by the Nordic Myeloma Study (Group (NMSG). In both trials, the EORTC QLQ-C30 questionnaire, supplemented with 11 items relating to interferon toxicity, was used. The first was a randomized controlled trial (NMSG 4/90) evaluating the addition of interferon alpha-2b to melphalan and prednisone during induction, maintenance and relapse. During the first 12 months, patients on interferon reported more chills, fever, fatigue, pain, nausea/vomiting, appetite loss and dry skin than the control patients, and a slight reduction of global health and quality of life. From 12 months onward there were no significant differences in any score between the two groups. In a later trial (NMSG 5/94) evaluating the effect of high-dose chemotherapy with stem cell support in patients under 60 years of age with newly diagnosed myeloma, interferon was used as maintenance. During the maintenance phase, symptom and toxicity scores were not significantly different from those in control patients under 60 years of age in the previous trial. Thus, interferon appeared to be well tolerated after high-dose chemotherapy with stem cell support.

A Multiple Myeloma (MM), IgG-lambda stage III-A was diagnosed in a 41-year-old-man. After VAD cycles IgG decreased from 7.5 to 2.4 g/dL. were mobilized with cyclophosphamide and 10 micrograms/Kg G-CSF. Three days after the collection of peripheral stem cell, the patient had fever, nausea, vomiting, liquid stools, shoulder and knee arthralgia and dehydration. Upper GI endoscopy showed esophageal candidiasis and ulcerative necrotic lesions both in stomach and duodenum; the biopsy confirmed necrosis. Simultaneously, the appearance of purpura with maculopapular lesions of diverse sizes appeared in the feet progressing to the limbs and trunk. Hematuria and proteinuria were also observed. Skin biopsy showed leukocytoclastic vasculitis. Renal biopsy showed focal and segmental glomerulonephritis. Serum ANCA, cryoglobulins, anti-HCV and RF were negative, and serum monoclonal IgG was 1290 mg/dL. Daily treatment with i.v. methylprednisolone pulses for 3 days improved skin lesions and digestive involvement. Macroscopic hematuria and proteinuria improved after two months of steroid treatment.

Primary plasma cell leukemia (PPCL) is a rare form of disease accounting for 1-2 percent of myelomas. Between September 1990 and November 2000, among 540 patients with myeloma studied, 24 fulfilled the criteria of PPCL (4.4 percent). We found high frequencies of female patients (62 percent), Bence Jones proteinuria (79 percent), anemia (88 percent), bleeding (54 percent), confusional syndrome (42 percent), weight loss (71 percent), hepatomegaly (25 percent), splenomegaly (21 percent), leukocytosis (62 percent), and thrombocytopenia (71 percent). High serum levels of creatinine, calcium, lactate dehydrogenase (LDH), and beta(2)-microglobulin were detected in 50 percent, 37 percent, 58 percent, and 71 percent, respectively. Four patients were treated with vincristine, melphalan, cyclophosphamide, prednisone, and adriamycin (VMCPA), 12 with vincristine, adriamycin, and dexamethasone (VAD), and 8 with M-80 (oral melphalan 80 mg/m(2) plus dexamethasone 40 mg/m(2)). There was a trend toward lower values of Karnofsky score (P=0.07) and higher values of LDH (P=0.2) in the VAD group. Other clinical characteristics were comparable among the three groups. Complete plus partial responses were achieved in one and six patients treated with VMCPA and M-80, respectively. All patients treated with VAD failed to respond to treatment. Patients receiving the M-80 regimen experienced higher platelet toxicity (P=0.05), vomiting (P<0.0003), and mucositis. Also, the need for red blood cell transfusions was higher in the M-80 group. Median overall survival was 60 days. Overall survival was better in patients achieving complete or partial response. In conclusion, our study illustrates that intermediate doses of melphalan plus dexamethasone are an effective chemotherapy regimen for this aggressive disease. Response to treatment is the only prognostic factor for survival in these patients.

High-dose melphalan (HDM) has been adopted as standard therapy in the treatment of multiple myeloma. This treatment is associated with non-selective cytotoxicity, causing oral mucositis as the major non-hematological side-effect. Amifostine is a cytoprotector which prevents toxicity induced by anticancer therapy. We prospectively compared two groups of patients who either received (group A, n = 21) or did not receive (group B, n = 20) amifostine (740 mg/m(2)) before HDM (200 mg/m(2)) followed by autologous peripheral blood progenitor cell transplantation. The occurrence of severe oral mucositis was significantly decreased in group A in comparison to group B (33% vs 65%, P < 0.05). Six patients in group A required opioid analgesic therapy during a mean period of 4.8 days as compared to eight patients for 6.5 days in group B (P = NS). Delayed vomiting was less frequent in group A (43% vs 70%, P = 0.07) and significantly less severe in group A (grade 2-4) vomiting: two patients vs nine patients, P < 0.02). No difference was observed between the two groups in either hematological toxicity after HDM or in response rate. Grade I emesis was the only immediate side-effect observed after amifostine administration. We conclude that amifostine can reduce mucositis induced by HDM.

Amifostine treatment may allow chemotherapy dose increases beyond those permitted by autologous hematopoietic stem cell transplantation. In a recent study in patients with solid tumors receiving a high-dose regimen of etoposide, ifosfamide, and carboplatin plus autologous stem cell transplantation, amifostine pretreatment was associated with significant reductions in time to neutrophil and thrombocyte engraftment, fewer days of neutropenic fever, less need for salvage antibiotic therapy. Also, there were significant reductions in grade 3 or 4 stomatitis/diarrhea, and delayed nausea/vomiting. A phase I/II study in patients with refractory/high-risk malignancies indicated that a 140% increase of high-dose melphalan (up to 280 mg/m2) can be safely used with amifostine and autologous stem cell transplantation with manageable mucosal toxicity and a reduced incidence of regimen-related toxicity. Preliminary findings in another phase II study indicate that melphalan 280 mg/m2 can also be safely used with amifostine/stem cell transplantation in the treatment of patients with myeloma. Additional studies are ongoing or planned to examine the potential hematoprotective and hematostimulating effects of amifostine in the setting of high-dose chemotherapy and autologous stem cell transplantation.

The aims of this study were to describe how a group of patients with different malignant diseases perceived symptom distress (SD), functional status (FS) and health-related quality of life (HRQOL) on admission to the hospital for stem-cell transplantation (SCT), to compare the obtained data regarding FS and HRQOL with similar data from two general-population groups, and to relate the results to disease- and treatment-specific data. Fifty-one patients participated in the study. Three instruments were used to collect data: SFID-SCT, SIP and SWED-QUAL. The majority of the patients (92%) reported ongoing symptoms even before the SCT with tiredness (67%) and anxiety (53%) as the two most commonly reported symptoms. Although tiredness and anxiety were reported to be the most frequently occurring symptoms, these symptoms were not considered to cause that much distress. Instead, vomiting, reduced mobility and fever, although less commonly occurring, were reported as highly distressing when present. Compared with the general-population groups, the patients reported significantly poorer FS and HRQOL but no statistically significant correlations were found between SD, FS or HRQOL and the time since the last chemotherapy cycle or cycles respectively. Patients with advanced disease and patients with multiple myeloma were found to report more SD and poorer FS and HRQOL.

Bortezomib (formerly PS-341), a promising new drug for the treatment of multiple myeloma, recently received accelerated approval from the U.S. Food and Drug Administration (FDA) for the therapy of patients with progressive myeloma after previous treatment. Two phase II studies of bortezomib used the same schedule of twice-weekly i.v. dosing for the first 2 weeks of each 3-week cycle. In a randomized study of 54 patients, two doses were compared (1.0 and 1.3 mg/m2) and objective responses occurred at both dose levels (23% versus 35%), including one complete response in each arm. In the other phase II study, 202 heavily pretreated patients (median of six prior therapies) all received the same schedule at 1.3 mg/m2. Of 188 evaluable patients, complete responses occurred in five (3%) and partial responses occurred in 47 (25%). The median duration of response was 365 days. The most clinically relevant adverse events were asthenic conditions, nausea, vomiting, diarrhea, thrombocytopenia, and a peripheral neuropathy that often was painful. This report highlights the FDA analysis supporting the accelerated approval.

Severe hypercalcemia is a life-threatening medical emergency. It is most commonly caused by malignant tumors, but can also be caused by primary hyperparathyroidism or less often by a dysregulated production of active vitamin D in granulomatous disorders. Symptoms include nausea, vomiting, renal insufficiency, severe dehydration, lethargy, confusion, and even coma. Severity of symptoms, calcium concentrations, and the overall status of the patient are important considerations in selecting appropriate therapy. Hydration to correct volume depletion is the cornerstone of acute therapy. Loop diuretics may be added to saline hydration after extracellular fluid volume has been replenished to enhance urinary calcium excretion and mitigate fluid overload from rehydration. Calcitonin and intravenous infusion of bisphosphonates reduce serum calcium levels by interfering with calcium release from the skeleton. Dialysis with a low or zero calcium dialysate is reserved for patients who are refractory to these measures. Corticosteroids are effective with hypercalcemia due to increased vitamin D levels and in multiple myeloma.

Multiple myeloma (MM), a malignancy of the plasma cells, accounts for an estimated 14% of all newly diagnosed hematologic malignancies. Advances in chemotherapy and stem cell transplantation have improved survival rates, but MM remains incurable. Bortezomib (Velcade, Millennium Pharmaceuticals, Inc., Cambridge, MA), a first-in-class proteasome inhibitor, has been approved for patients with MM who have received at least two prior treatments and have demonstrated disease progression on the most recent one. During clinical trials, most side effects were manageable with standard interventions. The most common toxicities were asthenic conditions (fatigue, malaise, and weakness), gastrointestinal disturbances (nausea, vomiting, diarrhea, and constipation), thrombocytopenia, peripheral neuropathy, pyrexia, and anemia. Supportive therapies and strategies for side-effect management can prevent worsening of these symptoms, thereby avoiding dose reductions and treatment delays. Oncology nurses play a key role in ensuring the proper and safe administration of bortezomib and often are the first to identify the signs of side effects. Patient education about anticipated side effects and close monitoring of patients can lead to symptom management interventions that are essential to patient comfort and safety.

We report on a randomised trial that aimed to compare the efficacy of continued daily prednisolone treatment during the entire induction phase, with prednisolone given for 2 weeks of each cycle in combination with VMCP (vincristine, melphalan, cyclophosphamide, prednisolone)-interferon-alpha 2b (IFN-alpha 2b) treatment in 299 previously untreated elderly patients (median age: 67 years) with multiple myeloma. After completion of induction treatment patients were randomised to IFN-alpha 2b with or without prednisolone, thrice weekly. Response rate was 62% in the continuous and 60% in the control arm (intent to treat analysis, P=0.81). Progression-free survival [median: 20 months vs. 19 months; hazard ratio (HR): 0.99, 95% confidence interval (CI): 0.74-1.33, P=0.97] and overall survival (median: 34 months vs. 37 months; HR: 1.16, 95% CI: 0.85-1.59, P=0.35) were similar in both groups. Reduced performance status (Eastern Cooperative Oncology Group, grades 2-4) was the predominant risk factor for poor survival followed by age >65 years, high beta2-microglobulin, and impaired renal function. There was more grades 3-4 dyspnoea and cardiac impairment and grades 1-2 hyperglycaemia, but less nausea, emesis and anaemia in patients on continuous prednisolone therapy. In conclusion, continuing prednisolone treatment during the entire duration of the induction phase with VMCP-IFN-alpha 2b did not improve outcome.
