[Show abstract][Hide abstract] ABSTRACT: Smoking adversely affects hematopoietic stem cell transplantation outcome. We asked whether smoking affected outcome of newly diagnosed acute myeloid leukemia (AML) patients treated with chemotherapy. Data were collected on 280 AML patients treated with high-dose cytarabine and idarubicin-containing regimens at Roswell Park Cancer Institute who had smoking status data at diagnosis. Patients' gender, age, AML presentation (de novo vs. secondary), white blood cell (WBC) count at diagnosis, karyotype and smoking status (never vs. ever) were analyzed. Among the 161 males and 119 females with a median follow-up of 12.9 months, 101 (36.1%) had never smoked and 179 (63.9%) were ever smokers. The proportion of patients between never and ever smokers was similar to respect to age, AML presentation, WBC count at diagnosis or karyotype based on univariate analysis of these categorical variables. Never smokers had a significantly longer overall survival (OS) (60.32 months) compared to ever smokers (30.89; p = 0.005). In multivariate analysis incorporating gender, age, AML presentation, WBC count, karyotype and smoking status as covariates, age, karyotype and smoking status retained prognostic value for OS. In summary, cigarette smoking has a deleterious effect on OS in AML.

[Show abstract][Hide abstract] ABSTRACT: Previous studies have demonstrated a modest association between smoking and leukemia particularly for myeloid disorders. Our objective was to examine whether changing trends in cigarette smoking prevalence nationally and within selected states parallel similar trends in mortality from leukemia. Trends in national smoking rates were correlated with trends in leukemia mortality rates obtained from the Centers for Disease Control and Prevention and the Surveillance Epidemiology and End Results registry, respectively. State-specific correlations were assessed from 1984 to 2004 using smoking prevalence data from the Behavioral Risk Factor Surveillance System and leukemia mortality data from National Vital Statistics System. Correlations were computed using the Spearman rank correlation coefficient. Leukemia mortality decreased overall in the United States in parallel with decreased smoking. Analyzed on a state-specific basis, leukemia mortality decreased in states where smoking rates declined markedly but remained unchanged where smoking prevalences were relatively stable. The findings suggest that declining rates of leukemia mortality are associated with changing patterns of smoking behavior.

[Show abstract][Hide abstract] ABSTRACT: Smoking is associated with both acute myeloid leukemia (AML) and lung cancer. We therefore searched our database for concomitant presentation of AML and lung cancer. Among 775 AML cases and 5225 lung cancer cases presenting to Roswell Park Cancer Institute between the years January 1992 and May 2008 we found 12 (1.5% of AML cases; 0.23% of lung cancer cases) cases (seven metachronous and five synchronous) with AML and lung cancer. All but one patient were smokers. There were no unique characteristic of either AML or lung cancer in these patients. Nine patients succumbed to AML, one died from an unrelated cause while undergoing treatment for AML, one died of lung cancer and one patient is alive after allogeneic transplantation for AML. In summary, this study supports the need for effective smoking cessation programs.
