We reviewed the efficacy of three agents advocated as ancillary therapy in myeloma patients. Intramuscularly administered immune serum globulin (gamma globulin) was ineffective in preventing infection. Hemoglobin level was improved in some myeloma patients receiving androgens. However, the response rate and the degree of leukopenia or thrombocytopenia were not superior with androgen-melphalan-prenisone combination therapy, as compared with those resulting from the two-drug combination without androgen. A controlled study evaluating androgen plus melphalan has not been done. The long-term administration of fluoride, supplemented by calcium and androgen, induced radiologically apparent bone fluorosis, but strengthening of lytic bone was not observed. Neither objective nor subjective benefit was demonstrated in a controlled study comparing the effects of fluoride (without calcium supplement) with those of the placebo.

The authors report the case of a 72 year old man admitted to hospital for thoracic pain, who was found to have an Igd myeloma of lambda type. The diagnosis, suspected, in view of anemia, raised sedimentation rate and abnormal electrophoresis of serum proteins, was confirmed by marrow examination after sternal aspiration and by the use of a specific anti-serum during immuno-electrophoresis and on Ouchteriony medium. There were radiological lesions of diffuse, decalcifying myelomatous type. The course was characterised by : 1) a constant tendency to anemia, then preterminal thrombocytopenia, whereas the leukopenia remained moderate. 2) The secondary onset of Bence-Jones proteinuria and mild albuminuria with the aggravation of pre-existing renal failure. 3) Repeated attacks of infection and the intermittent onset of mental confusion, the etiology of which was not clear. Death occurred ten months later. No autopsy was carried out. In the light of this case, the authors review the world literature and the special characteristics of IgD myeloma.

The clinical and pathological findings in 46 patients with cryptococcosis at Memorial Sloan-Kettering Cancer Center from 1956 to 1972 are reported. The striking predilection for cryptococcal infection in patients with leukemias and lymphomas is again confirmed. Of 41 patients with neoplastic disease, those with chronic lymphatic leukemia (CLL), Hodgkin's Disease, chronic myelogenous leukemia (CML), myeloma and lymphosarcoma had the highest incidence of cryptococcosis. In all cases, neoplastic disease was widespread when infection occurred. All of these patients had leukopenia and absolute lymphopenia at the time of infection. Thirty-nine were on steroids. Thirty-one patients with neoplastic disease had disseminated infection. Review of pathology revealed a spectrum of inflammatory lesions. Histiocytic-lymphocytic infiltrates occurred in the central nervous system in 10 patients. In six cases, reaction was granulomatous. There were single instances of suppurative and fibrotic reactions. Mortality from infection was high in patients with neoplastic disease. Twenty-four of 28 deaths occurred within 60 days as a result of infection. Within one year, 10 more patients died, nine of cryptococcosis. Only three survived more than one year, and all patients died within 600 days. Twenty-nine patients with neoplastic disease received amphotericin B. Only nine survived more than 60 days.

Piperazinedione given iv once every 3-4 weeks at a starting dose of 9-12 mg/m2 (4.5-12 mg/m2 for patients with myeloma) was evaluated in a Southwest Oncology Group phase II study for patients with far-advanced refractory lymphoma or multiple myeloma. Among 36 patients fully evaluable for tumor response (adequate trial), partial responses were observed in five (71%) of seven patients with Hodgkin's disease, in three (19%) of 16 patients with non-Hodgkin's lymphoma, and in none of 13 patients with multiple myeloma. Response was observed by the time of the second (five patients) or third (three patients) course. The median duration of response was 3.7 months (range, 1-17+ months). The dose-limiting toxic effects were hematologic, with 18 (50%) of 36 patients evaluable for toxicity experiencing severe leukopenia (wbc count less than 2000/mm3) and 22 (61%) experiencing severe thrombocytopenia (platelet count less than 50,000/mm3). Twenty patients had a decrease from their pretreatment hemoglobin level of greater than or equal to 2 g/100 ml. Hematologic toxic effects were often unpredictable and in several patients quite prolonged. This study indicates that piperazinedione had definite antitumor activity in patients with Hodgkin's disease and further trials in this disease using the drug at a reduced dose in combination with other effective drugs appear warranted.

Eighty-nine patients with multiple myeloma resistant to melphalan were randomized to receive cyclophosphamide plus prednisone (CP) (47 patients) or cyclophosphamide plus BCNU plus prednisone (CBP) (42 patients). No differences were detected in the two groups prior to therapy. Objective responses occurred in three (7%) of the CP patients and in seven (17%) of the CBP patients. About 40% of the patients in each group achieved some response. Toxic reactions consisted mainly of leukopenia and thrombocytopenia. Median survival was not different in the two groups. The median survival time was 31 months among those patients with an objective response and 9.4 months among those without an objective response. The addition of BCNU to CP increased the frequency of objective response, but not significantly. This triple combination (CBP) cannot be recommended.

Leukopenia and thrombocytopenia were studied after loading doses of melphalan (5 mg/daily for 18-25 days) in 71 myeloma patients. Seventy per cent of the patients developed pronounced leukopenia (white cells less than 2.0 X 10(9)/l) and/or thrombocytopenia (platelets less than 100 X 10(9)/l). The patients with pronounced and moderate hematological side-effects, respectively, were compared for weight and age. The body weight was the same in the two groups, indicating that the patient's weight is of minor importance for the dosage of melphalan. There was a numerical difference in age, on the borderline for statistical significance, indicating that the age of the myeloma patient may be of minor importance for the dosage of melphalan. It is possible that more pronounced age differences may be of greater importance in this respect. Fifteen patients with myeloma were treated with cyclophosphamide. Compared with melphalan, the effect on white cells was the smae, while the incidence of thrombocytopenia was statistically significantly lower with cyclophosphamide.

A prospective randomized study of the effects of two different therapeutic regimens was conducted in 41 patients with multiple myeloma resistant to therapy with melphalan. The results of treatment with cyclophosphamide plus prednisone were compared with those of cyclophosphamide, prednisone, and chloroquine. Chloroquine, which inhibits the repair process of DNA in animals, has reportedly produced responses to alkylating agents to which the animal had been resistant. No significant differences in response to the doses used with either regimen could be found. Toxocity consisted mainly of leukopenia and thrombocytopenia.

Mitoxantrone is a dihydroxyanthracenedione derivative which as intravenous mono- and combination therapy has demonstrated therapeutic efficacy similar to that of standard induction and salvage treatment regimens in advanced breast cancer, non-Hodgkin's lymphoma, acute nonlymphoblastic leukaemia and chronic myelogenous leukaemia in blast crisis; it appears to be an effective alternative to the anthracycline component of standard treatment regimens in these indications. Mitoxantrone is also effective as a component of predominantly palliative treatment regimens for hepatic and advanced ovarian carcinoma. Limited studies suggest useful therapeutic activity in multiple myeloma and acute lymphoblastic leukaemia. Regional therapy of malignant effusions, hepatic and ovarian carcinomas has also been very effective, with a reduction in systemic adverse effects. Mitoxantrone inhibits DNA synthesis by intercalating DNA, inducing DNA strand breaks, and causing DNA aggregation and compaction, and delays cell cycle progression, particularly in late S phase. In vitro antitumour activity is concentration- and exposure time-proportional, and synergy with other antineoplastic drugs has been demonstrated in murine tumour models. Leucopenia may be dose-limiting in patients with solid tumours, whereas stomatitis may be dose-limiting in patients with leukaemia. Other adverse effects are usually of mild or moderate severity although cardiac effects, particularly congestive heart failure, may be of concern, especially in patients with a history of anthracycline therapy, mediastinal irradiation or cardiovascular disease. Mitoxantrone displays an improved tolerability profile compared with doxorubicin and other anthracyclines, although myelosuppression may occur more frequently. Thus, mitoxantrone is an effective and better tolerated alternative to the anthracyclines in most haematological malignancies, in breast cancer and in advanced hepatic or ovarian carcinoma. Further studies may consolidate its role in the treatment of these and other malignancies.

Idarubicin is a 4-demethoxy-anthracycline analogue of daunorubicin which, when administered intravenously in combination with cytarabine, has therapeutic efficacy superior to that of standard induction and salvage treatment regimens in acute myelogenous leukaemia. Idarubicin alone or in combination regimens has also been effective in limited studies in patients with other acute leukaemias, advanced breast cancer, multiple myeloma and non-Hodgkin's lymphoma. Idarubicin is more lipophilic than its parent drug daunorubicin. It intercalates DNA, induces DNA strand breaks and delays cell cycle progression. Leucopenia is often dose-limiting in patients with solid tumours treated with idarubicin, and most other adverse effects are similar in incidence and severity to those experienced with other anthracycline cytotoxic agents, except for alopecia which appears to occur with a reduced incidence and severity. Cardiotoxic effects have been reported with idarubicin as with other anthracyclines, but animal data and preliminary clinical findings suggest the possibility of reduced cardiotoxicity with idarubicin--a potentially important advantage if confirmed on further study. A maximum cumulative dose of idarubicin beyond which the incidence of cardiotoxicity rapidly increases has not been determined. Thus, intravenous idarubicin is a useful alternative to other anthracyclines (particularly in combination with cytarabine) in the treatment of acute myelogenous leukaemia, and there is some evidence that it is less cardiotoxic than other anthracycline drugs. Further studies are required to establish the use of intravenous idarubicin as a replacement for other intravenous anthracyclines, especially its effect on response duration and survival, and to confirm the evidence of reduced cardiotoxic effects. The role of idarubicin as consolidation and maintenance therapy for various malignancies requires further investigation, as does the potential use of oral idarubicin which is currently under development.

We reviewed 32 cases of necrobiotic xanthogranuloma and 16 cases from the world literature. Necrobiotic xanthogranuloma is a destructive dermal and subcutaneous xanthogranuloma that most frequently involves the face (periorbital region) and trunk. Monoclonal gammopathy is common (IgG-kappa in 23 cases and IgG-lambda in nine cases), and cryoglobulins have also been found. Low complement levels, anemia, and leukopenia are frequently present. Bone marrow examination shows plasma cell proliferation and, rarely, true myeloma. We describe mucosal, muscle, and systemic lesions, including xanthogranulomatous myocardial lesions. The clinical course is chronic and often progressive. Low-dose chlorambucil treatment is safe and effective, but individual patients have responded to treatment with corticosteroids, melphalan, local radiation, and plasma exchange.
