“…29 Studies suggest that total fat intake is significantly inversely associated with survival or positively related to treatment failure (defined as recurrence or new cancer of the contralateral breast). [30][31][32][33][34] Some studies suggest an adverse prognostic effect for obesity. 35,36 Although still inconclusive, these findings raise the possibility that the improved survival of Japanese patients may be related in part to their low mean body weight (obesity rate according to the International Obesity Task Force: 3.3% of Japanese women vs 32% of NHW women 37 ).…”

BACKGROUND:It has been established that disparities by ethnicity in the rates of breast cancer diagnoses and disease‐specific survival (DSS) exist in the United States. However, few studies have assessed differences specifically between Asians and other ethnic groups or among Asian subgroups.METHODS:The authors used the Surveillance, Epidemiology, and End Results database to identify patients who were diagnosed with invasive breast cancer between 1988 and 2008. Clinicopathologic features, treatment, and DSS rates were compared among broad ethnic groups and among Asian subgroups.RESULTS:In total, there were 658,691 patients in the study, including 511,701 non‐Hispanic white (NHW) women (77.7%), 57,890 black women (8.8%), 45,461 Hispanic white (HW) women (6.9%), and 43,639 Asian women (6.6%). The Asian cohort was divided into the following subgroups: Filipino, Chinese, Japanese, Indian/Pakistani, Korean, Vietnamese, Hawaiian/Pacific Islander, and other. Patients in all the Asian subgroups, except Japanese, were younger at diagnosis than NHW patients. After adjustment for disease stage, Japanese patients diagnosed with stage I through III disease had better DSS rates than patients in the NHW group or in the other Asian subgroups. Hawaiian/Pacific Islander patients with stage III or IV disease had worse DSS rates than NHW patients and patients in the other Asian subgroups. All other Asian subgroups had DSS rates similar to the DSS rate in the NHW group.CONCLUSIONS:The current results indicated that disparities exist for Asian women with breast cancer who reside in the United States compared with NHW groups and among Asian subgroups. Differences in presenting clinicopathologic features may affect DSS rates, suggesting that further investigation of these disparities is warranted to increase early detection and treatment for specific subgroups.

“…An empirical case can be made for both dietary and exercise interventions for breast cancer patients, with data suggesting that obesity at diagnosis, increased fat intake, and weight gain during follow-up are related to recurrence and poorer survival (Holm et al, 1993;Saxe, Rock, Wicha, & Schottenfeld, 1999;Willett, 1999;Zhang, Folsom, Sellers, Kushi, & Potter, 1995).…”

Psychological interventions for adult cancer patients have primarily focused on reducing stress and enhancing quality of life. However, there has been expanded focus on biobehavioral outcomeshealth behaviors, compliance, biologic responses, and disease outcomes-consistent with the Biobehavioral Model of cancer stress and disease course. The author reviewed this expanded focus in quasi-experimental and experimental studies of psychological interventions, provided methodologic detail, summarized findings, and highlighted novel contributions. A final section discussed methodologic issues, research directions, and challenges for the coming decade.Cancer remains a significant national problem, with over 1 million Americans diagnosed each year. The adjustment process for cancer survivors may be burdensome and lengthy, and deteriorations in quality of life are underscored if they also have adverse health effects. A previous review noted the significant quality-of-life gains that can be achieved with psychological interventions (Andersen, 1992), a conclusion echoed here. In this review, I look more broadly and include biobehavioral responses and disease outcomes as areas important for intervention efforts. Although there are proportionately fewer studies that have included the latter, multimodal interventions and assessment of psychological, behavioral, and biologic mechanisms are the pathways for future research.The Biobehavioral Model of cancer stress and disease course (Andersen, Kiecolt-Glaser, & Glaser, 1994) provides the organizational framework for the discussion. Represented in Figure 1, the model includes psychological (e.g., stress and quality of life), behavioral (e.g., health behaviors and compliance), and biologic (e.g., neuroendocrine and immune) components and specifies the pathways by which health outcomes (e.g., disease endpoints-recurrence, disease free interval) might be affected. A complete discussion of the model is available elsewhere , as only brief summaries are provided prior to each section.Studies conducted since 1992 with adult cancer patients are reviewed; selected investigations prior to that period are included because of their importance, novelty, or absence from the earlier article focusing on quality of life (Andersen, 1992). Each component of the model is considered as an outcome following psychological interventions. Prior to each, I review descriptive findings and highlight prominent correlational investigations. For all experimental studies, accrual and retention rates and patient characteristics are provided, as these areas are in need of methodologic attention, as discussed later in the article. Although tedious at times, specific techniques of interventions are provided to enable the reader to distinguish among those with similar labels. Quasi-experimental designs are included for emerging areas. With few exceptions, all studies included psychological outcomes, but in the first section, I focus on studies with only these endpoints.

“…A study of treatment failure and dietary patterns in women with ER-positive breast cancers 28 showed that vitamin E intake at the time of diagnosis was a statistically significant prognostic indicator of treatment failure within the first 2 years after diagnosis (OR ϭ 1.19 for each milligram per 10-MJ increase). These last results are in line with our own findings and suggest that the effect of vitamin E on breast cancer might vary with the stage of the disease.…”

The role of plasma oxidant-antioxidant status in survival after breast cancer surgery was investigated in a cohort of patients (n ‫؍‬ 363) hospitalized in Southern France between 1989 and 1992. The median follow-up was 8 years after surgery for histologically confirmed breast cancer. Plasma analyses were performed after diagnosis and before surgery and adjuvant therapy. We found an inverse relationship between plasma lipoperoxides (MDA) and tumor size at diagnosis, together with higher lipoperoxide levels in node-negative tumors than in node-positive ones (TNM). The longitudinal approach revealed an increased risk of recurrence for patients with plasma lipoperoxides in the highest tertile of the sample (RR ‫؍‬ 2.1, 95%CI 1.1-4.0). In addition, the risk of recurrence increased (RR ‫؍‬ 1.7, 95%CI 1.0 -3.0), after adjustment for the known prognostic factors (TNM), for patients with plasma lipid-adjusted vitamin E levels of over 22 mol/l. The risk of breast cancer death was twice as great for patients with plasma lipid-adjusted vitamin E levels above this value. Excesses of plasma lipoperoxides and vitamin E appear to be factors in poor prognosis for breast cancer-specific survival (OVS) and disease-free survival (DFS), respectively, independent of tumor characteristics at diagnosis. Several hypotheses are advanced to explain the possible role of plasma vitamin E as a factor in poor prognosis for survival. © 2002 Wiley-Liss, Inc. Key words: breast cancer; survival; lipoperoxides; vitamin EA previous cross-sectional study that we had conducted 1 showed a statistically significant higher plasma vitamin E level in breast cancer patients than in controls. In line with these data, another of our studies 2 had shown that lipid peroxidation measured by malondialdehyde formation was lower in patients than in controls. Moreover, it was found that plasma antioxidants and lipid peroxidation were inversely associated with tumor size. 3 These results were completed by cross-sectional studies 4,5 of other cancer sites, which also showed that the risk of tumor growth increased 3-fold in the class of cancer patients in which plasma lipoperoxides were below 0.3 mol/l.These findings suggested that the oxidant-antioxidant status of patients could influence tumor growth and proliferative activity and subsequently overall survival and risk of recurrence after surgery. This hypothesis has also been investigated in other studies of both animal 6,7 and human tumors. 8 The present longitudinal study was therefore conducted to investigate the plasma concentrations of lipoperoxides, vitamin E (an antioxidant lipophile) and glutathione peroxidase (an antioxidant enzyme) as relevant prognostic factors for risk of death or recurrence for breast cancer patients.
