    Abstract: Dietary fat may play a role in lung carcinogenesis. Findings from epidemiologic studies, however, remain inconsistent. In this pooled analysis of 10 prospective cohort studies from the United States, Europe, and Asia, we evaluated the associations of total and specific types of dietary fat with lung cancer risk. Methods Cox regression was used to estimate hazard ratios (HRs) and 95% CIs in each cohort. Study-specific risk estimates were pooled by random- or fixed-effects meta-analysis. The first 2 years of follow-up were excluded to address potential influence of preclinical dietary changes. Results Among 1,445,850 participants, 18,822 incident cases were identified (mean follow-up, 9.4 years). High intakes of total and saturated fat were associated with an increased risk of lung cancer (for highest v lowest quintile: HR, 1.07 and 1.14, respectively; 95% CI, 1.00 to 1.15 and 1.07 to 1.22, respectively; P for trend for both 〈 .001). The positive association of saturated fat was more evident among current smokers (HR, 1.23; 95% CI, 1.13 to 1.35; P for trend 〈 .001) than former/never smokers ( P for interaction = .004), and for squamous cell and small cell carcinoma (HR, 1.61 and 1.40, respectively; 95% CI, 1.38 to 1.88 and 1.17 to 1.67, respectively; P for trend for both 〈 .001) than other histologic types ( P for heterogeneity 〈 .001). In contrast, a high intake of polyunsaturated fat was associated with a decreased risk of lung cancer (HR, 0.92; 95% CI, 0.87 to 0.98 for highest v lowest quintile; P for trend = .02). A 5% energy substitution of saturated fat with polyunsaturated fat was associated with a 16% to 17% lower risk of small cell and squamous cell carcinoma. No associations were found for monounsaturated fat. Conclusion Findings from this large, international cohort consortium suggest that modifying dietary fat intake (ie, replacing saturated fat with polyunsaturated fat) may reduce lung cancer risk, particularly among smokers and for squamous cell and small cell carcinoma.

    Development of a melanoma risk prediction model incorporating MC1R genotype and indoor tanning exposure.
    American Society of Clinical Oncology (ASCO) ; 2012

    Abstract: 8574 Background: Invasive melanoma is the second most common cancer in young adults, yet they exhibit poor skin-protective behavior. We previously demonstrated a significant association between melanoma risk, melanocortin receptor (MC1R) polymorphisms, and indoor ultraviolet light (UV) exposure. As existing melanoma risk models do not take these factors into account, we investigated whether these variables would improve the predictive ability of a clinical risk model, especially in a younger population. Methods: We determined MC1R genotype and collected self-reported phenotypic and UV (indoor and outdoor) exposure variables from 923 melanoma cases and 813 healthy controls between ages 25 – 59 from the Minnesota Skin Health Study. These data were initially used to develop a clinical melanoma risk model (Model A) with conventional risk factors (i.e. age; gender; hair, skin, and eye color; mole count, freckling, and family melanoma history). We then developed a second model (Model B) combining outdoor UV, indoor UV, and MC1R genotype variables with those in Model A to determine if the model’s predictive ability improved. Finally, we assessed the predictive ability of both models when confined to younger subjects (ages 25-35). Results: The clinical model, combining conventional melanoma risk factors (Model A), yielded an area under the receiver operating characteristic curve (AUC) of 0.72 (95% CI 0.70 – 0.75). Incorporating outdoor UV, indoor UV, and MC1R genotype variables (Model B) increased the AUC to 0.75 (p=0.001, 0.72 – 0.77). Confining the analyses to younger subjects substantially increased the AUC of Model A to 0.78 (0.72 – 0.84) and Model B to 0.83 (p=0.007, 0.78-0.88). Conclusions: This preliminary risk model is the first in melanoma to demonstrate that the addition of genotypic data and indoor UV exposure results in a measurable increase in predictive ability when compared to models comprised only of clinical and outdoor UV exposure variables. The enhanced predictive ability of the model (AUC 〉 0.80) when limited to younger individuals suggests the potential for developing tools to facilitate targeted screening and prevention strategies in melanoma.

    Abstract: The impact of lymphedema or related arm symptoms on health-related quality of life (HRQOL) in breast cancer (BrCa) survivors has not been examined using a large population-based cohort. Patients and Methods The Iowa Women's Health Study (IWHS) collected self-report data for lymphedema, arm symptoms, and HRQOL (Medical Outcomes Study Short Form-36) in 2004 and data for cancer diagnosis, treatment, and behavioral and health characteristics between 1986 and 2003. We studied 1,287 women, age 55 to 69 years at baseline, who developed unilateral BrCa. We used cross-sectional analyses to describe the prevalence of lymphedema and arm symptoms and multivariate-adjusted generalized linear models to compare HRQOL (physical functioning, bodily pain, general health, physical and emotional role limitations, vitality, social functioning, and mental health) between the following three survivor groups: women with lymphedema (n = 104), women with arm symptoms without diagnosed lymphedema (n = 475), and women without lymphedema or arm symptoms (n = 708). Results The mean (± SE) time between BrCa diagnosis and lymphedema survey was 8.1 ± 0.2 years. Of BrCa survivors, 8.1% self-reported diagnosed lymphedema, and 37.2% self-reported arm symptoms. Knowledge of lymphedema was low among survivors without diagnosed lymphedema (n = 1,183). After multivariate adjustment, women with diagnosed lymphedema or arm symptoms without diagnosed lymphedema had lower physical and mental HRQOL compared with women without lymphedema or arm symptoms. Effect sizes were mild to moderate. There was a dose-response relation between number of arm symptoms and lower HRQOL. Conclusion In the IWHS, HRQOL was lower for BrCa survivors with diagnosed lymphedema and for those with arm symptoms without diagnosed lymphedema. Clinical trials are needed to determine what interventions can improve lymphedema and impact HRQOL for BrCa survivors.

    Adherence to the World Cancer Research Fund/American Institute for Cancer Research Recommendations for Cancer Prevention Is Associated With Better Health-Related Quality of Life Among Elderly Female Cancer Survivors
    American Society of Clinical Oncology (ASCO) ; 2013

    Abstract: The 2007 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) diet and physical activity guidelines encourage cancer survivors to follow its cancer prevention recommendations. We evaluated whether adherence to the WCRF/AICR recommendations was associated with health-related quality of life (HRQOL) among elderly female cancer survivors. Patients and Methods A total of 2,193 women with a confirmed cancer diagnosis (1986 through 2002) in the Iowa Women's Health Study were identified. We calculated a WCRF/AICR recommendation adherence score (range, 0 to 7), assigning one point each for seven recommendations. Physical and mental component summary scores (PCS, MCS) from the Medical Outcomes Study Short Form–36 Health Survey were compared by recommendation adherence scores. Results Mean adherence score was 4.0 ± 1.2. Overall, higher adherence to the WCRF/AICR guidelines was significantly associated with better PCS and MCS after adjustment for age, education, marital status, number of comorbidities, smoking, cancer stage, and current cancer treatment (P trend 〈 .001 for both). PCS was 43.5 versus 37.0 and MCS was 54.2 versus 52.0 among women with adherence scores ≥ 5 compared with women scoring ≤ 3. Adherence to the physical activity recommendation was associated with higher PCS and MCS after adjusting for demographic and medical confounders, body mass index, and dietary recommendation adherence. For the body weight recommendation, adherence was associated with higher PCS but lower MCS, whereas adherence to the dietary recommendations was associated with higher MCS only. Conclusion Following the lifestyle guidelines for cancer prevention may improve HRQOL among elderly female cancer survivors. Physical activity may be a key lifestyle factor to improve HRQOL.
