Lin YC, Cheng HH, Chen SC, Shen WC, Huang YT. Pre-treatment high body mass index is associated with poor survival in Asian premenopausal women with localized breast cancer. J Cancer 2021; 12:4488-4496. [PMID: 34149912 PMCID: PMC8210548 DOI: 10.7150/jca.59133] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Accepted: 05/19/2021] [Indexed: 12/29/2022] Open
Abstract
Background: Obesity is associated with poor prognosis in breast cancer patients. This study aimed to evaluate the effect of obesity measured by body mass index (BMI) on survival of Taiwanese breast cancer patients in a single institution. Methods: We observed 5000 patients who were diagnosed with stage I-III breast cancer between 1990 and 2005. Information on BMI at diagnosis, and clinical follow-up for disease recurrence and death, up to 20 years post-diagnosis were available. BMI (in kg/m2) categories included normal weight (BMI<24), overweight (24≤BMI<27), and obesity (BMI≥27), according to recommendations from the Bureau of Health Promotion of Taiwan. The role of BMI and other known prognostic factors for patient survival were evaluated in this patient cohort. Results: Obesity was associated with advanced stage, higher nuclear grade, and higher percentages of estrogen receptor (ER) positive. The median age of patients with a higher BMI was greater than the median age of patients with a lower BMI. Obesity was an independent prognostic factor of overall survival (OS) (P<0.001), but not disease-free survival (DFS) (P=0.067). We subsequently analyzed the impact of age-stratified BMI (age<50 and age≥50 years) to ameliorate the impact of age bias. Following subset analyses, obesity correlated with shorter DFS (P=0.004) and OS (P=0.009) only in women<50 years of age. Multivariate analysis revealed that BMI was an independent prognostic factor for both DFS and OS in this group of patients. Subset analysis revealed that in women <50 years old, the impact of BMI on survival was associated with higher stage, ER negativity. Conclusion: BMI is an independent prognostic factor of OS and DFS in breast cancer patients aged<50 years. Although the cause-effect relationship between obesity and survival is unclear, we recommend that weight control measures in young breast cancer survivors should be considered.

Abstract
INTRODUCTION For the last two decades, obesity rates have been increasing in both developed and developing countries, with the number of obese women roughly doubling during this period (Stevens et al. in Popul Health Metr 10(1):33, 2012). Obesity represents one of the biggest epidemics of the 21st century. The aim of this retrospective study is to characterise the outcomes of gynaecologic surgeries in cases of extremely obese women with a body mass index (BMI) over 40 kg/m2. METHODS This study is a retrospective case control study in a single-centre setting. Our clinical database was searched for gynaecological operations performed on morbidly obese patients (BMI > 40 kg/m2) between 2009 and 2014 in the Department of Gynaecology and Obstetrics at Hannover Medical School. We matched these results with random patients of normal body weight who had similar surgical procedures and diseases. RESULTS We included 97 obese patients in our case group and 99 patients in the control group. We found an association between a strongly elevated BMI and peri- and postoperative morbidity. Both intraoperative and postoperative complications are significantly increased in morbid obesity with a BMI over > 40 kg/m2. We observed intraoperative complications in 55.6% and postoperative complications in 50.5% of patients with extreme obesity. In contrast, the complication rate in the control group with a normal BMI was 11% intraoperatively (p = 0.0001) and 3% postoperatively (p = 0.0001). The data showed that perioperative and postoperative morbidity could be reduced by laparoscopic surgery in many cases, with a significant lower rate of difficulties with closing the wound, a significant shorter duration of surgery and a significant lower rate of infections combined with a significant lower reoperation rate and shorter hospital stay. In gynaecological-oncological diseases, we could demonstrate a reduced radicality during the operative procedure due to extreme obesity. DISCUSSION Dealing with the growing number of obese patients is essential, because the problems emerging from obesity are manifold for the treating hospitals as well as the general health system. For this high-risk patient group, it is indispensable to obtain a thorough overview of the patient's overall situation preoperatively to ensure good perioperative care and complications management.

Abstract
INTRODUCTION Decision-making regarding adjuvant chemotherapy has been based on clinical and pathological features. However, such decisions are seldom consistent. Web-based predictive models have been developed using data from cancer registries to help determine the need for adjuvant therapy. More recently, with the recognition of the heterogenous nature of breast cancer, genomic assays have been developed to aid in the therapeutic decision-making. METHODS We have carried out a comprehensive literature review regarding online prognostication tools and genomic assays to assess whether online tools could be used as valid alternatives to genomic profiling in decision-making regarding adjuvant therapy in early breast cancer. RESULTS AND CONCLUSIONS Breast cancer has been recently recognized as a heterogenous disease based on variations in molecular characteristics. Online tools are valuable in guiding adjuvant treatment, especially in resource constrained countries. However, in the era of personalized therapy, molecular profiling appears to be superior in predicting clinical outcome and guiding therapy.

Abstract
Background The burden of breast cancer in Asia is escalating. We evaluated the impact of ethnicity on survival after breast cancer in the multi-ethnic region of South East Asia. Methodology/Principal Findings Using the Singapore-Malaysia hospital-based breast cancer registry, we analyzed the association between ethnicity and mortality following breast cancer in 5,264 patients diagnosed between 1990 and 2007 (Chinese: 71.6%, Malay: 18.4%, Indian: 10.0%). We compared survival rates between ethnic groups and calculated adjusted hazard ratios (HR) to estimate the independent effect of ethnicity on survival. Malays (n = 968) presented at a significantly younger age, with larger tumors, and at later stages than the Chinese and Indians. Malays were also more likely to have axillary lymph node metastasis at similar tumor sizes and to have hormone receptor negative and poorly differentiated tumors. Five year overall survival was highest in the Chinese women (75.8%; 95%CI: 74.4%–77.3%) followed by Indians (68.0%; 95%CI: 63.8%–72.2%), and Malays (58.5%; 95%CI: 55.2%–61.7%). Compared to the Chinese, Malay ethnicity was associated with significantly higher risk of all-cause mortality (HR: 1.34; 95%CI: 1.19–1.51), independent of age, stage, tumor characteristics and treatment. Indian ethnicity was not significantly associated with risk of mortality after breast cancer compared to the Chinese (HR: 1.14; 95%CI: 0.98–1.34). Conclusion In South East Asia, Malay ethnicity is independently associated with poorer survival after breast cancer. Research into underlying reasons, potentially including variations in tumor biology, psychosocial factors, treatment responsiveness and lifestyle after diagnosis, is warranted.

Abstract
Obese women have an increased risk for post-menopausal breast cancer. The physiological mechanism by which obesity contributes to breast tumourigenesis is not understood. We previously showed that HCCR-1 oncogene contributes to breast tumourigenesis as a negative regulator of p53 and detection of HCCR-1 serological level was useful for the diagnosis of breast cancer(.) In this study, we found that the HCCR-1 level is elevated in breast cancer tissues and cell lines compared to normal breast tissues. We identified apolipoprotein E (ApoE) interacting with HCCR-1. Our data show that HCCR-1 inhibits anti-proliferative effect of ApoE, which was mediated by diminishing ApoE secretion of breast cancer cells. Finally, HCCR-1 induced the severe obesity in transgenic mice. Those obese mice showed severe hyperlipidaemia. In conclusion, our results suggest that HCCR-1 might play a role in the breast tumourigenesis while the overexpression of HCCR-1 induces the obesity probably by inhibiting the cholesterol-lowering effect of ApoE. Therefore, HCCR-1 seems to provide the molecular link between the obesity and the breast cancer risk.

Abstract
PURPOSE This study aimed to identify predictors of changes in weight and body composition among women receiving chemotherapy for breast cancer. PATIENTS AND METHODS Data were from 49 women age 40-54 receiving chemotherapy for breast cancer. Weight, height, and body composition measurements from dual-energy x-ray absorptiometry (DEXA) scanning were completed at baseline (within 1 month of beginning chemotherapy) and 12 months. Caloric intake was assessed from food diaries at baseline, 6 and 12 months, and physical activity was measured by questionnaire at baseline, 3, 6, 9, and 12 months. RESULTS Baseline body mass index (BMI) was inversely associated with gains in weight (P = .01) and fat mass in torso (P = .006). Women of normal weight gained an average of 4.3 pounds and increased fat mass in torso and arms. Overweight women lost 3.0 pounds, and obese women lost 4.1 pounds, and neither group increased body fat. Decreased physical activity was associated with weight gain (P = .047). Additional predictors of increased fat mass in torso were younger age (P = .023) and treatment with tamoxifen (P = .015). Predictors of loss of bone mineral content included older age (P = .004) and treatment with aromatase inhibitor (P = .024), whereas treatment with bisphosphonate prevented bone loss (P < .0001). CONCLUSION Women receiving chemotherapy for breast cancer who are of normal weight at the time of breast cancer diagnosis are more likely to gain weight and body fat during the following year than overweight or obese women.

Abstract
The prevalence of obesity among children, adolescents and adults has been dramatically increasing worldwide during the last several decades. The obesity epidemic has been recognized as one of the major global health problems, because its health hazard is linked to a number of common diseases including breast and prostate cancers. Obesity is caused by combination of genetic and environmental factors. While genetic contribution to obesity has been known to be significant, the genetic factors remain relatively unchanged. Recent studies have highlighted the involvement of environmental "obesogens", i.e. the xenobiotic chemicals that can disrupt the normal development and homeostatic control over adipogenesis and energy balance. Several lines of evidence suggest that increasing exposure to chemicals with endocrine-disrupting activities (endocrine-disrupting chemicals, EDCs) contributes to the increased obesity. The cellular and molecular mechanisms underlying obesogen-associated obesity are just now being appreciated. In this paper, we comprehensively reviewed current knowledge about the role of estrogen receptors alpha and beta (ERalpha and ERbeta) in regulation of energy metabolism pathways, including glucose transport, glycolysis, tricarboxylic acid (TCA) cycle, mitochondrial respiratory chain (MRC), adenosine nucleotide translocator (ANT) and fatty acid beta-oxidation and synthesis, by estrogens; and then examined the disturbance of E(2)/ER-mediated energy metabolism pathways by environmental obesogens; and finally, we discussed the potential implications of disturbance of energy metabolism pathways by obesogens in obesity and pointed out several key aspects of this area that need to be further explored. A better understanding of the cellular and molecular mechanisms underlying obesogen-associated obesity will lead to new approaches for slow down and/or prevention of the increased trend of obesity associated with exposure to obesogens.

Abstract
The purpose of this meta-analysis was to examine the effectiveness of aerobic exercise interventions on cardiopulmonary function and body composition in women with breast cancer. Of 24 relevant studies reviewed, 10 studies (N = 588) met the inclusion criteria. The findings indicated that aerobic exercise significantly improved cardiopulmonary function as assessed by absolute VO2 peak (standardized mean difference [SMD] .916, p < .001), relative VO2 peak (SMD .424, p < .05), and 12-minute walk test ( SMD .502, p < .001). Similarly, aerobic exercise significantly improved body composition as assessed by percentage body fat (SMD -.890, p < .001), but body weight and lean body mass did not change significantly. Aerobic exercise during or after cancer adjuvant therapy seems to be an effective means of improving cardiopulmonary function and decreasing percentage body fat in women with breast cancer. Further studies are needed to examine the long-term benefits of aerobic exercise.

Abstract
Background Ki-67 expression is a possible risk biomarker and is currently being used as a response biomarker in chemoprevention trials. Mammographic breast density is a risk biomarker and is also being used as a response biomarker. We previously showed that Ki-67 expression is higher in specimens of benign breast cells exhibiting cytologic atypia that are obtained by random periareolar fine needle aspiration (RPFNA). It is not known whether there is a correlation between mammographic density and Ki-67 expression in benign breast ductal cells obtained by RPFNA. Methods Included in the study were 344 women at high risk for developing breast cancer (based on personal or family history), seen at The University of Kansas Medical Center high-risk breast clinic, who underwent RPFNA with cytomorphology and Ki-67 assessment plus a mammogram. Mammographic breast density was assessed using the Cumulus program. Categorical variables were analyzed by χ2 test, and continuous variables were analyzed by nonparametric test and linear regression. Results Forty-seven per cent of women were premenopausal and 53% were postmenopausal. The median age was 48 years, median 5-year Gail Risk was 2.2%, and median Ki-67 was 1.9%. The median mammographic breast density was 37%. Ki-67 expression increased with cytologic abnormality (atypia versus no atypia; P ≤ 0.001) and younger age (≤50 years versus >50 years; P ≤ 0.001). Mammographic density was higher in premenopausal women (P ≤ 0.001), those with lower body mass index (P < 0.001), and those with lower 5-year Gail risk (P = 0.001). Mammographic density exhibited no correlation with Ki-67 expression or cytomorphology. Conclusion Given the lack of correlation of mammographic breast density with either cytomorphology or Ki-67 expression in RPFNA specimens, mammographic density and Ki-67 expression should be considered as potentially complementary response biomarkers in breast cancer chemoprevention trials.

Abstract
The potential for recurrence causes considerable distress for breast cancer survivors. Major information sources for survivors and providers offer few clear recommendations for postdiagnosis lifestyle change related to recurrence. To design interventions to improve long-term survivors' care and quality of life, we must know what survivors are doing to prevent recurrence in the absence of solid evidence, whether survivors' perceptions and behaviors correspond to hypothesized modifiable risk factors for recurrence, and whether survivors are adopting behaviors that could otherwise be harmful to their health. Our review first addresses the general lack of consensus on the impact of specific lifestyle factors on breast cancer recurrence and the resulting equivocal lifestyle recommendations for survivors. Second, we describe inadequacies of the studies of survivors' lifestyle changes related to recurrence. Because much of the existing knowledge about modifiable risk factors for recurrence comes from studies of survivors whose participation and behavior change were potentially influenced by their concern about recurrence, we need large, population-based observational studies of randomly selected breast cancer survivors, adequately representing the target population. Critical are data on lifestyle change from prediagnosis to postdiagnosis and changes over time after diagnosis, extensive data on conventional and nonconventional treatments, and the temporal relationship between behaviors and treatments, and inclusion of the full complement of potential lifestyle risk factors for recurrence. Understanding in detail the current status of survivors' perceptions and behaviors related to modifiable risk factors for recurrence can provide considerable practical information to inform future interventions and communication strategies for breast cancer survivors.

Abstract
Western lifestyle, characterized by reduced physical activity and a diet rich in fat, refined carbohydrates, and animal protein is associated with high prevalence of overweight, metabolic syndrome, insulin resistance, and high plasma levels of several growth factors and sex hormones. Most of these factors are associated with breast cancer risk and, in breast cancer patients, with increased risk of recurrences. Recent trials have proven that such a metabolic and endocrine imbalance can be favorably modified through comprehensive dietary modification, shifting from Western to Mediterranean and macrobiotic diet.

Genetic, Anthropometric, and Lifestyle Factors Associated with IGF-1 and IGFBP-3 Levels in Hispanic and Non-Hispanic White Women. Cancer Causes Control 2005; 16:1147-57.

Abstract
Circulating concentrations of IGF-I and IGFBP-3 are associated with risk of pre-menopausal breast cancer. Racial differences in levels of these factors have been reported, and determinants of IGF-I and IGFBP-3 levels within racial and ethnic groups are unclear. In this study we examine genetic, anthropometric, diet, and lifestyle factors that may predict serum levels of IGF-I and IGFBP-3 among Hispanic and non-Hispanic white women. A sample of healthy controls participating in the SHINE (Southwest Hormone, Insulin, Nutrition, and Exercise Study) case-control breast cancer in Arizona, Colorado, New Mexico, and Utah were included in these analyses. Subjects included 210 Hispanic and 284 non-Hispanic white women. Hispanic women had significantly lower levels of IGFBP-3 (mean=3764.3 mcg/ml) after adjusting for age, body size, physical activity, menopausal status, and dietary factors than non-Hispanic white women (mean = 4058.0 mcg/ml; p<0.01). The CC genotype of the -202 A>C polymorphism of the IGFBP3 gene was associated with lower IGFBP-3 levels in both ethnic groups. The frequency of the IGFBP3 C allele differed between Hispanic (0.65) and non-Hispanic white women (0.53), but serum levels of IGFBP-3 were lower for Hispanic women than non-Hispanic after accounting for IGFBP3 genotype. Body size indicators, vigorous physical activity, and dietary factors appeared to influence serum levels of IGF-1 and the ratio of IGF-1 to IGFBP-3 in pre-menopausal women more than in post-menopausal women. On the other hand, using aspirin/NSAIDs appeared to increase IGFBP-3 levels significantly among pre-menopausal Hispanic women. Results from this study suggest that differences in IGFBP-3 levels exist in Hispanic and non-Hispanic white women. These differences could be due to the combined effects of genetic and behavioral factors which could account for ethnic differences in the risk of breast cancer and other chronic diseases.
