Etoposide, dexamethasone, cytarabine, and cisplatin in vincristine, doxorubicin, and dexamethasone-refractory myeloma

Based on remarkable activity in refractory lymphomas, a combination of etoposide, cisplatin (both administered by 4-day continuous infusions), cytarabine (Ara-C), and dexamethasone (EDAP) was evaluated in 20 patients with advanced myeloma refractory to standard melphalan and prednisone (MP) and/or vincristine, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and dexamethasone (VAD) and even to high doses of melphalan (HDM) (seven patients). Forty percent of patients responded regardless of previously recognized risk factors (eg, duration of drug resistance, tumor mass, and serum lactic dehydrogenase [LDH] level). While the median survival was only 4.5 months, patients with good performance (Zubrod less than 2) and low or intermediate tumor stage survived more than 14 months compared with only 2 months for the remaining group. EDAP could be readily administered in the outpatient clinic, but neutropenic fever prompted hospital admission in 80% of patients, half of whom developed penumonia and sepsis, a fatal outcome in four patients. Severe myelosuppression was of short duration, so that subsequent cycles could be administered every 3 to 4 weeks. No serious extramedullary toxicity, including renal toxicity, was encountered. Marrow toxicity and hence infectious complications may be reduced by elimination of Ara-C without compromising treatment efficacy. We conclude that the lack of cross-resistance with VAD and even HDM makes EDAP or a similar combination an attractive regiment to be formally explored in an alternating sequence with VAD in high-risk myeloma.     

Premenopausal intakes of vitamins A, C, and E, folate, and carotenoids, and risk of breast cancer.

Intakes of vitamins A, C, and E, folate, and carotenoids have been hypothesized to reduce the risk of breast cancer. However, previous epidemiological studies on these nutrients and breast cancer risk have been inconclusive, and have included primarily postmenopausal women. We examined the intake of these nutrients in relation to breast cancer risk among 90,655 premenopausal women ages 26-46 years in 1991 in the Nurses' Health Study II. Nutrient intake was assessed with a validated food-frequency questionnaire at baseline in 1991 and in 1995. During 8 years of follow-up from 1991 to 1999, we documented 714 incident cases of invasive breast cancer. Overall, none of the vitamins and carotenoids was strongly related to a reduced risk of breast cancer. However, intake of vitamin A, including preformed vitamin A and carotenoids, was associated with a reduced risk of breast cancer among smokers; participants in the highest quintile of total vitamin A intake had a multivariate relative risk of 0.28 (95% confidence interval 0.12-0.62; P, test for trend <0.001; P, test for interaction <0.001) compared with those in the lowest quintile of intake. We found no evidence that higher intakes of vitamins C and E, and folate in early adult life reduce risk of breast cancer. However, intake of vitamin A may be related to a reduced risk of breast cancer among smokers.     

Selenium, lycopene, alpha-tocopherol, beta-carotene, retinol, and subsequent bladder cancer

To examine the association between serum nutrients and the development of bladder cancer we measured selenium, alpha-tocopherol, lycopene, beta-carotene, retinol, and retinol-binding protein in serum collected from 25,802 persons in Washington County, MD, in 1974. Serum samples were kept frozen at -70 degrees C. In the subsequent 12-year period, 35 cases of bladder cancer developed among participants. Comparisons of serum levels in 1974 among cases and two matched controls for each case showed that selenium was significantly lower among cases than controls (P = 0.03), lycopene was lower among cases at a borderline level of significance (P = 0.07), and alpha-tocopherol was nonsignificantly lower (P = 0.13). For selenium there was a nearly linear increase in risk with decreasing serum levels (P = 0.03). When examined by tertiles, the odds ratio associated with the lowest tertile of selenium compared to the highest tertile was 2.06. Serum levels of retinol, retinol-binding protein, and beta-carotene were similar among cases and controls. These results support a role for selenium in the prevention of bladder cancer.
