Understanding the breast cancer experience of Asian American women.

Abstract: Breast cancer is the most common form of cancer in women and affects women across all ethnic groups. Although the psychosocial impact of breast cancer is being studied, there is little information on ethnic minorities. To better understand the breast cancer experience of Asian American women, we conducted key informant and focus group interviews. Six professionals participated in the key informant interviews. A total of 34 Asian American breast cancer survivors participated in focus group interviews, including Korean (n=10), Chinese (n=11), and a mixed Asian group (n=13). The common themes identified in this series of qualitative studies included: lack of knowledge about breast cancer; medical care issues such as cost and amount of time spent with physician; cultural factors related to beliefs about illness, gender role and family obligations (e.g. self-sacrifice) and language barriers; the importance of spirituality; and psychosocial concerns related to worry about children, burdening the family, body image and sexual health concerns. A primary source of support and coping for Asian American women with breast cancer was their spiritual beliefs. The results from this qualitative study have been used to prepare a survey instrument to examine these issues in a larger sample of Asian American women.

Health risks associated with cigar smoking.

Abstract: This article summarizes principal findings from a conference convened by the American Cancer Society in June 1998 to examine the health risks of cigar smoking. State-of-the-science reports were presented and 120 attendees (representing government and private agencies, academia, health educators, and tobacco control experts) participated in panels and summary development discussions. The following conclusions were reached by consensus: (1) rates of cigar smoking are rising among both adults and adolescents; (2) smoking cigars instead of cigarettes does not reduce the risk of nicotine addiction; (3) as the number of cigars smoked and the amount of smoke inhaled increases, the risk of death related to cigar smoking approaches that of cigarette smoking; (4) cigar smoke contains higher concentrations of toxic and carcinogenic compounds than cigarettes and is a major source of fine-particle and carbon monoxide indoor air pollution; and (5) cigar smoking is known to cause cancers of the lung and upper aerodigestive tract.

Genome-wide association study of glioma and meta-analysis.

Abstract: Gliomas account for approximately 80 % of all primary malignant brain tumors and, despite improvements in clinical care over the last 20 years, remain among the most lethal tumors, underscoring the need for gaining new insights that could translate into clinical advances. Recent genome-wide association studies (GWAS) have identified seven new susceptibility regions. We conducted a new independent GWAS of glioma using 1,856 cases and 4,955 controls (from 14 cohort studies, 3 case–control studies, and 1 population-based case-only study) and found evidence of strong replication for three of the seven previously reported associations at 20q13.33 (RTEL), 5p15.33 (TERT), and 9p21.3 (CDKN2BAS), and consistent association signals for the remaining four at 7p11.2 (EGFR both loci), 8q24.21 (CCDC26) and 11q23.3 (PHLDB1). The direction and magnitude of the signal were consistent for samples from cohort and case–control studies, but the strength of the association was more pronounced for loci rs6010620 (20q,13.33; RTEL) and rs2736100 (5p15.33, TERT) in cohort studies despite the smaller number of cases in this group, likely due to relatively more higher grade tumors being captured in the cohort studies. We further examined the 85 most promising single nucleotide polymorphism (SNP) markers identified in our study in three replication sets (5,015 cases and 11,601 controls), but no new markers reached genome-wide significance. Our findings suggest that larger studies focusing on novel approaches as well as specific tumor subtypes or subgroups will be required to identify additional common susceptibility loci for glioma risk.

Prostate cancer incidence in 43 populations worldwide: An analysis of time trends overall and by age group

Abstract: Prostate cancer is a significant public health burden and a major cause of morbidity and mortality among men worldwide. Analyzing geographic patterns and temporal trends may help identify high-risk populations, suggest the degree of PSA testing, and provide clues to etiology. We used incidence data available from the International Agency for Research on Cancer (IARC) and certain cancer registries for 43 populations across five continents during a median period of 24 years. Trends in overall prostate cancer rates showed five distinct patterns ranging from generally monotonic increases to peaking of rates followed by declines, which coincide somewhat with changes in the prevalence of PSA testing. Trends in age-specific rates generally mirrored those in the overall rates, with several notable exceptions. For populations where overall rates increased rapidly and then peaked, exemplified in North America and Oceania, the highest incidence tended to be most pronounced and occurred during earlier calendar years among older men compared with younger ones. For populations with almost continual increases in overall rates, exemplified in Eastern Europe and Asia, peaks were evident among men aged ≥ 75 years in many instances. Rates for ages 45-54 years did not clearly stabilize or decline in the majority of studied populations. Global geographic variation remained substantial for both overall and age-specific incidence rates regardless of levels of PSA testing, with the lowest rates consistently in Asia. Explanations for the persistent geographic differences and the continuing increases of especially early-onset prostate cancer remain unclear.

Identification of Novel Genetic Markers of Breast Cancer Survival

Abstract: Background: Survival after a diagnosis of breast cancer varies considerably between patients, and some of this variation may be because of germline genetic variation We aimed to identify genetic markers associated with breast cancer-specific survival Methods: We conducted a large meta-analysis of studies in populations of European ancestry, including 37954 patients with 2900 deaths from breast cancer Each study had been genotyped for between 200000 and 900000 single nucleotide polymorphisms (SNPs) across the genome; genotypes for nine million common variants were imputed using a common reference panel from the 1000 Genomes Project We also carried out subtype-specific analyses based on 6881 estrogen receptor (ER)-negative patients (920 events) and 23059 ER-positive patients (1333 events) All statistical tests were two-sided Results: We identified one new locus (rs2059614 at 11q242) associated with survival in ER-negative breast cancer cases (hazard ratio HR = 195, 95% confidence interval CI = 155 to 247, P = 191 x 10-8) Genotyping a subset of 2113 case patients, of which 300 were ER negative, provided supporting evidence for the quality of the imputation The association in this set of case patients was stronger for the observed genotypes than for the imputed genotypes A second locus (rs148760487 at 2q242) was associated at genome-wide statistical significance in initial analyses; the association was similar in ER-positive and ER-negative case patients Here the results of genotyping suggested that the finding was less robust Conclusions: This is currently the largest study investigating genetic variation associated with breast cancer survival Our results have potential clinical implications, as they confirm that germline genotype can provide prognostic information in addition to standard tumor prognostic factors © 2015 © The Author 2015 Published by Oxford University Press
