Human leukocyte interferon and intermittent high-dose melphalan-prednisone administration in the treatment of multiple myeloma: a randomized clinical trial from the Myeloma Group of Central Sweden.

In a randomized clinical trial intermittent high-dose melphalan/prednisone (MP) treatment has been compared with human leukocyte interferon (IFN) administration. Three to 6 X 10(6) IU of IFN was given im daily. Therapy was continued to progression of the disease. Fifty-five patients were randomized to receive MP and 75 were randomized to receive IFN. Forty-four percent of the patients receiving MP responded to therapy as opposed to only 14% of the patients receiving IFN (P less than 0.001). This difference was mainly due to a low response rate in IFN-treated IgG myelomas, while the response rate for IgA and Bence Jones myelomas did not differ significantly between the two treatment groups. Median duration of response was shorter for IFN-responding patients (23 months) as compared to patients in the MP group (35 months). During follow-up, second-line therapy was given more frequently in the IFN group (91%) than in the MP group (59%). Time on initial treatment was significantly shorter in the IFN group (3 months) than in the MP group (19 months). Since more patients responded to second-line therapy in the IFN group than in the MP group, total survival did not differ significantly between the two groups.

Intermittent high-dose melphalan/prednisone vs continuous low-dose melphalan treatment in multiple myeloma.

Patients with newly diagnosed multiple myeloma were randomly allotted to an intermittent high-dose melphalan/prednisone (MP) treatment (120 patients) or a continuous low-dose melphalan (M) regimen (99 patients). The median observation time was 59 months (range 33-84). Response to therapy was obtained in 45% of the MP group and 31% of the M group (P less than 0.05). No significant difference in response with regard to clinical stage was noted. Median survival was 36 months in the MP group and 29 months in the M group. Survival was longer in stage I and II myeloma than in the stage III cases, at least in the MP group. The median and 5-yr survival rates in stages I and II were significantly better in the MP than in the M group. Response to therapy was associated with length of survival, median survival being 62 months in responding patients and 20 months in non-responders. The MP and M groups did not differ in this respect.

Treatment of acute nonlymphoblastic leukemia in adults with daunorubicin-DNA complex: a preliminary report.

Forty-four adult patients under 60 years of age with acute nonlymphoblastic leukemia were randomized for induction treatment with one of the following three regimens: R 1 = courses of daunorubicin on day 1 + ARA-C on days 1--5; R 2 = courses of daunorubicin on days 1 and 2 + ARA-C on days 4--8; R 3 = courses of daunorubicin-DNA complex on days 1--2 + ARA-C on days 4--8. Out of 14 patients, 9 went into remission on R 1, 6 out of 14 on R 2, and 8 out of 16 on R 3. The preliminary results suggest that daunorubicin-DNA complex has the same efficacy for inducing remission as daunorubicin alone, if the same time intervals and dosages are used.

Splenectomy--a surgical panorama.

A five-year material of splenectomies (1970-74) is presented. The material was divided according to the indications for splenectomy as follows: radicality (Group I), iatrogenic hemorrhage Group II), traumatic ruptures (Group III), hematological cases (Group IV) and miscellaneous cases (Group V). There was a large increase in the hematological group over the period due to the addition of splenectomy in the staging procedure for Hodgkin's disease. The mortality was highest in group I and lowest in group IV, as also was the incidence of complications. No patient with Hodgkin's disease died of the operation and the staging laparotomy for this disease, which gives valuable information, thus seems sufficiently safe to warrant routine use.

L-asparaginase and prednisolone pretreatment followed by rubidomycin and cytosine arabinoside for induction of remission in adult patients with acute myeloblastic leukaemia.

77 unselected adult patients with acute myeloblastic leukaemia (AML), including practically all AML patients from an area with 1.9 million inhabitants, were randomized for either (1) 5 days pretreatment with 1-asparaginase and prednisolone followed by a combination of rubidomycin and cytosine arabinoside (ARAP), or (2) treatment with a combination of rubidomycin, cytosine arabinoside and prednisolone without 1-asparaginase pretreatment (RAP). Complete remission was induced with ARAP in 12 patients (31%) and with RAP in 13 patients (34%). Thus pretreatment with 1-asparaginase did not improve the therapeutic response. The overall remission frequency was significantly higher below the age of 60; 50% compared to 13% above this age. Side-effects such as liver dysfunction, nausea and vomiting were more common in patients pretreated with 1-asparaginase. Sterilization of the gut did not improve the remission frequency with either regime.
