ABSTRACT
PURPOSE: We report the results of intensive chemotherapy with high-dose melphalan (HDM) following conventional-dose cytoreductive chemotherapy in previously untreated patients with myeloma. PATIENTS AND METHODS: From 1986 to 1991, 53 previously untreated patients with myeloma received HDM 200 mg/m2 plus methylprednisolone 1.5 g daily (MP) for 5 days with autologous bone marrow transplantation (ABMT) after cytoreductive chemotherapy. RESULTS: At the time of HDM administration, responses to induction therapy were complete remission (CR) in nine patients, partial remission (PR) in 38, and no response (NR) in six. Following HDM, all but one patient responded, with 40 patients achieving a CR (75%). There was one treatment-related death following HDM. The median time to reach a WBC count more than 1,000/microL and platelet count more than 25,000/microL was 19 days (range, 13 to 30) and 24 days (range, 15 to 55), respectively. The median duration of response has not been reached at 20 months, and it is significantly longer for patients in CR than for those in PR (P < .025). Currently, with a median follow-up duration of 31 months (range, 6 to 58), 12 patients are dead and 40 are alive, and the estimated probability of survival at 54 months is 63%. Multivariate analysis found hemoglobin (Hb) more than 10 g/dL (P = .012), and stage A disease (P = .001) at diagnosis to be favorable indicators for survival. CONCLUSION: Myeloma patients who are able to receive HDM plus ABMT following conventional chemotherapy achieve a high proportion of CRs, which may be associated with prolonged survival.

A pilot randomised placebo controlled trial using tamoxifen in healthy women at increased risk of developing breast cancer, has been undertaken in order to evaluate the problems of accrual, acute symptomatic toxicity, compliance, and safety as a basis for subsequent large national multicentre trials designed to test whether tamoxifen can chemoprevent breast cancer. From October 1986 until June 1993, 2012 healthy women with an increased risk of developing breast cancer, usually because of a strong family history, were randomly allocated to receive tamoxifen 20 mgs/day or placebo for up to 8 years if possible. Accrual remained high in spite of extensive informed consent regarding potential risk. Acute symptomatic toxicity was low for participants on tamoxifen or placebo and compliance remained correspondingly high with a predicted 77% of women on tamoxifen and 82% of women on placebo continuing medication at 5 years. There was a significant increase in hot flushes (34% versus 20%) mostly in premenopausal women (p < 0.005), vaginal discharge (16% versus 4%, p < 0.005), and menstrual irregularities (14% versus 9%, p < 0.005). The requirements for hormone replacement therapy for women on tamoxifen or placebo were the same. Safety monitoring indicates no adverse anti oestrogenic effects of tamoxifen. There was no obvious effect of tamoxifen on bone mineral densities (single photon radial absorption). The fibrinogen and antithrombin III were both lowered, resulting in no observed detrimental effect on the ratio of these clotting factors. There was a significant reduction in the serum cholesterol maintained out to 5 years. Annual pelvic assessment using transvaginal ultrasound indicates an increased incidence of uterine fibromata and benign ovarian cysts.(ABSTRACT TRUNCATED AT 250 WORDS)

The results of high-dose chemotherapy with melphalan or melphalan (carmustine) etoposide for 66 consecutive patients with relapsed or resistant Hodgkin's disease are described. 55 patients were evaluable for response and 22% of these achieved complete remission and 59% partial remission. The actuarial survival at 2 years was 45% and the principal factors determining survival were the sensitivity of the disease to therapy given before high-dose chemotherapy and the type of treatment received. Intensive chemotherapy with autologous bone marrow transplantation can produce long-term survivors among patients for whom long-term survival would otherwise be improbable. However, this treatment remains toxic with an uncertain place in management.
