Breast cancer screening among Cambodian American women

Our aim was to describe and identify factors associated with breast cancer screening among Cambodian American women. We conducted a cross-sectional survey of 1,365 households using bilingual and bicultural interviewers. We found that low proportions of Cambodian American women were up to date on their clinical breast examinations (CBE; 42%) and mammograms (40%). More than 80% of women with female physicians have had at least one prior screening, and 52% have had the tests recently. Women with male Asian American physicians were less likely to have had screening as compared to women with female non-Asian physicians: ever had CBE (odds ratio [OR], 0.26); recent CBE (OR, 0.39); ever had mammogram (OR, 0.36); and recent mammogram (OR, 0.22). Breast cancer screening among Cambodian American women lags behind the general U.S. population. Tailored promotion efforts should address barriers and promote cancer screening by physicians, staff, and organizations serving this population.     

Breast cancer survivorship: expressed needs of black women

Studies have reported that race/ethnicity, socioeconomic status, access to care, early diagnosis, quality of care, and spirituality are important prognostic factors for a breast cancer diagnosis. This exploratory study seeks to identify the perceived needs of Black middle-income breast cancer survivors. The Delphi Technique, a qualitative research approach (for deriving cultural consensus), was used to assess needs of 62 Black middle-income socioeconomic position survivors. Survivors' expressed needs were to have (1) affordable, accessible, acceptable, and appropriate medical and support services; (2) a caring and loving family; (3) contacts for information regarding breast cancer symptoms or related health problems; (4) an intimate relationship with God; and (5) adequate resources for self and family care. This pilot study suggests Black breast cancer survivors, regardless of a middle-income socioeconomic position (SEP), experience similar socioecological stressors as low-income SEP survivors.     

Breast cancer and screening in American Indian and Alaska Native women

Data relative to breast cancer among American Indian and Alaska native (AI/AN) women are limited and vary by regions. Despite national decreases in breast cancer incidence and mortality rates, declines in these measures have not yet appeared among AI/AN women. Health disparities in breast cancer persist, manifest by higher stage at diagnosis, and lower screening rates compared to other racial and ethnic groups. Disproportionately more AI/AN are younger at diagnosis. Screening beginning at age 40, improving access, annual rescreening, community education and outreach, and mobile mammography for rural areas are ways to improve these disparities in breast cancer.     

Breast cancer in African American women: Epidemiology and tumor biology

Summary This review of published data on the epidemiology, pathology, and molecular biology of breast cancer in African American women seeks to identify how the etiology and presentation of the disease differ from those in white women. The crossover from higher to lower age-specific incidence rates in African American women at age 45 cannot be explained by current data on the distribution of risk factors. Data from six case-control studies suggest that the relative risks associated with both established and probable breast cancer risk factors are similar in African American and white women. Lower survival in African American compared to white women is primarily attributable to diagnosis at a later stage. However, evidence from a number of studies suggests that tumors in African American women may exhibit a more aggressive phenotype, which could also contribute to the survival disparity. Tumors in African American women are more likely to occur at a younger age, to be poorly differentiated and estrogen receptor negative, and to exhibit high grade nuclear atypia, more aggressive histology (more medullary and less lobular), and higher S-phase. Overexpression of p53 and erbB-2 occurs with similar frequency in African American and white women, although limited data suggest the former may exhibit different p53 mutation spectra. One study found high risk associated with a specific CYP1A1 polymorphism in African American but not white women. Additional studies of molecular differences in African American and white women are needed, with multifactorial assessment of the independent effects of molecular and conventional risk attributes.     

Breast cancer trends among black and white women in the United States.

PURPOSE: Overall US breast cancer mortality rates are higher among black women than white women, and the disparity is widening. To investigate this disparity, we examined incidence data and changes in mortality trends according to age, year of death (calendar period), and date of birth (birth cohort). Calendar period mortality trends reflect the effects of new medical interventions, whereas birth cohort mortality trends reflect alterations in risk factors. PATIENTS AND METHODS: Incidence data were obtained from the Connecticut and National Cancer Institute Surveillance, Epidemiology, and End Results registries and mortality data were obtained from the National Center for Health Statistics. Changes in age, period, and cohort mortality trends were analyzed with Poisson regression. RESULTS: For both races, breast cancer incidence rates for localized and regional disease diverged in the late 1970s. Almost concurrently, overall mortality rates diverged among blacks and whites. For both races, mortality increases with age, but blacks have higher mortality at age younger than 57. The calendar period curves revealed declining mortality for whites over the entire study period. For blacks, calendar period mortality declined until the late 1970s, and then sharply increased. After 1994, calendar period mortality declined for both. For women born between 1872 and 1950, trends in mortality were similar for blacks and whites. For women born after 1950, mortality decreased more rapidly for blacks. CONCLUSION: The widening racial disparity in breast cancer mortality seems attributable to calendar period rather than birth cohort effects. Thus, differences in response or access to newer medical interventions may largely account for these trends.     

Breast cancer screening: stages of adoption among Cambodian American women

BACKGROUND: Little information is available on the breast cancer screening behavior of Cambodian American women. METHODS: We identified households from multiple sources using Cambodian surnames and conducted a cross-sectional survey, administered by bilingual and bicultural interviewers. Breast cancer screening stages of adoption were examined based on concepts from the transtheoretical model of behavioral change. RESULTS: Our response rate was 73% (398 women in clinical breast exam (CBE) analysis, and 248 in mammography analysis) with approximately 25% each in the maintenance stage. We found significant associations between screening stage with physician characteristics. Asian American female physician increased the likelihood of being in the maintenance stage (CBE, OR = 10.1, 95% CI 2.8-37.1; mammogram, OR = 74.7,95% CI 8.3-674.6), compared to Asian American male physician with precontemplation/contemplation stage as our referent outcome. CONCLUSION: Results from this study support the need to promote regular breast cancer screening among Cambodian American women.     

Breast cancer in young women

About one in 300 women will be diagnosed with breast cancer before the age of 40. Advances in screening have not had an impact on mortality in women who are too young to be candidates for screening. Risk factors for early breast cancer include a lean body habitus and recent use of an oral contraceptive. Breast cancers in very young women are typically aggressive, in part owing to the over-representation of high-grade, triple-negative tumours, but young age is an independent negative predictor of cancer-specific survival. Very early age-of-onset also correlates strongly with the risk of local recurrence and with the odds of contralateral breast cancer. Given the high risks of local and distant recurrence in young women with invasive breast cancer, most (if not all) young patients are candidates for chemotherapy. It is hoped that by increasing breast cancer awareness, the proportion of invasive breast cancers that are diagnosed at 2.0 cm or smaller will increase and that this will lead to a reduction in mortality.     

Breast cancer in young women

The aim of this study is to evaluate the impact of CYP2D6 genotyping in predicting disease-free survival and toxicity in breast cancer patients treated with adjuvant tamoxifen. DNA from 91 patients was genotyped using the AmpliChip CYP450 GeneChip^®, Roche that facilitates the classification of individuals by testing 27 alleles. When patients were grouped into group 1 (*4/*4, *4/*41, *1/*5 and *2/*5) and group 2 (the remaining genotypes), a significant difference in disease-free survival (DFS) was observed between groups (P = 0.016). The mean DFS in group 1 was 95 months in contrast with 119 months in group 2. No significant relationship was found between the CYP2D6 genotype classification and severe, mild or no toxicity (P = 0.2). Nevertheless, severe, and mild toxicity was more frequent among poor metabolizer patients than in patients with a normal metabolizer pattern (18.8 and 43.8% vs. 10.7 and 36%, respectively). In breast cancer, patients treated with adjuvant tamoxifen, non-functional and severely impaired CYP2D6 variants are associated with a worse DFS and with a higher frequency of severe and mild toxicities. Larger studies of the CYP2D6 genotype-clinical outcomes association are needed to complement initial results.     

Breast cancer in young women

Although uncommon, breast cancer in young women is worthy of special attention due to the unique and complex issues that are raised. This article reviews specific challenges associated with the care of younger breast cancer patients, which include fertility preservation, management of inherited breast cancer syndromes, maintenance of bone health, secondary prevention, and attention to psychosocial issues.     

老年人乳腺癌

老年人乳腺癌与年轻人乳腺癌相比,恶性程度相对较低。临床以局部性或局部晚期癌较多。因老年患者生理变化,且常同时伴有其他疾病,治疗原则应选择对患者创伤及不良反应最小而能获得最大疗效的综合治疗,除基于疾病的分期外,要注重了解乳腺癌的生物学特征、患者体力情况、重要脏器器官功能及对拟定疗法的耐受能力。手术是可手术乳腺癌主要治疗手段之一,早期乳腺癌ER( )者,采用肿瘤局部扩大切除或加前哨淋巴结活检术(SLNB),术后加或不加放疗,辅助以内分泌治疗可达到满意控制肿瘤效果。局部晚期乳腺癌或肿瘤较大,ER( )者,可采用第三代芳香化酶抑制剂(3rdAI)行新辅助内分泌治疗,肿瘤缩小后采用缩小手术切除范围术式。对全身复发、转移高危及ER(-)患者,如体力情况尚好,可化疗。     

Breast cancer in young women

Recent evidence suggests that the incidence of local breast tumor recurrences and failures may be substantially lower than previously thought due to the widespread use of systemic adjuvant therapy and loco-regional treatments. Surgery is a fundamental aspect of the management of breast cancer, and the mainstay of loco-regional treatment. In younger women, the choice of surgical approach (radical mastectomy vs lumpectomy) is influenced by tumor size, multicentricity, breast volume, genetic predisposition to the disease, and the patient’s wishes, because breast resections can have a major impact on the patient’s quality of life. Currently, adjuvant radiotherapy is recommended for all women following breast surgery. It significantly reduces the rate of relapse and overall mortality. Contralateral risk-reducing mastectomy is recommended, proposed in women with a current or previous diagnosis of breast cancer, particularly those with known BRCA1/BRCA2 mutations, women in whom surveillance of the contralateral breast is complicated, and/or to improve symmetry in patients undergoing mastectomy followed by breast reconstruction.     

Breast cancer in very young women

Aims

The purpose was to analyse the characteristics, treatment, recurrences and survival of very young women with breast cancer.

Methods

212 female breast cancer patients ≤35 years old were treated during 1997-2007. The median follow-up time was 78 months.

Results

117 patients had lymph node metastases and 14 distant metastases at diagnosis. 81 (38%) tumours were hormone receptor negative and 130 (65%) grade 3. HER2 positivity was seen in 47 (34%) and triple negativity in 35 (26%) of the 137 tumours with known HER2 status. 140 women were treated with mastectomy and 68 with breast conserving surgery. 163 patients received postoperative radiotherapy, 175 adjuvant chemotherapy, 95 endocrine therapy and 18 trastuzumab. 63 patients experienced a recurrence, of which 20 had only a locoregional recurrence. 10 (15%) of the women with breast conserving surgery experienced ipsilateral breast tumour recurrence while ipsilateral thoracic wall recurrence was seen in 8 patients (6%) after mastectomy. Seven of these eight patients did not receive postmastectomy radiotherapy. DFI was shorter in patients with hormone receptor positive tumours. At the end of follow-up 44 women had died. The 5-year OS was 80%.

Conclusions

The 5-year OS for young women has become better but is still lower than for all breast cancer patients. DFI was shorter in patients with hormone receptor positive disease. Locoregional recurrences were seen more often after breast conserving surgery.     

Breast cancer treatment in older women

This article presents the author's current approaches to the management of breast cancer in older women, with emphasis on clinical and surgical treatment of the disease in this population. There are controversies surrounding the management of breast cancer in this population regarding adjuvant therapy, radiation therapy and surgical options. We endeavor to address these issues in the article.     

Breast cancer screening knowledge, attitudes, and practices among Korean American women

PURPOSE/OBJECTIVES: To describe the knowledge and beliefs about breast cancer and breast cancer screening and practices of clinical breast examination (CBE) and mammography of Korean American women. DESIGN: Cross-sectional survey. SETTING: Two Korean churches in a mid-sized Southeastern U.S. city. SAMPLE: A convenience sample of 107 Korean women ages 40 and older. METHODS: Data were collected using Champion's Health Belief Model instrument (susceptibility, seriousness, benefits, and barriers) and the Breast Cancer Knowledge test through mailed questionnaires. MAIN RESEARCH VARIABLES: Knowledge and beliefs about breast cancer screening and practices of CBE and mammography. FINDINGS: The percentages of Korean American women who ever had a CBE and mammography were 67 and 58, respectively. Among the Health Belief Model variables, women who never had a CBE had significantly lower knowledge scores and higher perceived barriers to CBE than those who had. Women who never had a mammogram reported significantly higher perceived barriers to mammography. Logistic regression analyses demonstrated that husband's nationality, regular checkups, and encouragement from family members and physicians were significant predictors of CBE and mammography use. CONCLUSIONS: The frequency of breast cancer screening practices among Korean American women is below national objectives. IMPLICATIONS FOR NURSING PRACTICE: As healthcare professionals in a culturally diverse nation, nurses need to increase their awareness of cultural variations and provide culturally and linguistically appropriate breast health education. Additional studies with women from a variety of settings are needed to validate present study findings.     

Breast cancer statistics, 2015: Convergence of incidence rates between black and white women

In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening. Approximately 231,840 new cases of invasive breast cancer and 40,290 breast cancer deaths are expected to occur among US women in 2015. Breast cancer incidence rates increased among non‐Hispanic black (black) and Asian/Pacific Islander women and were stable among non‐Hispanic white (white), Hispanic, and American Indian/Alaska Native women from 2008 to 2012. Although white women have historically had higher incidence rates than black women, in 2012, the rates converged. Notably, during 2008 through 2012, incidence rates were significantly higher in black women compared with white women in 7 states, primarily located in the South. From 1989 to 2012, breast cancer death rates decreased by 36%, which translates to 249,000 breast cancer deaths averted in the United States over this period. This decrease in death rates was evident in all racial/ethnic groups except American Indians/Alaska Natives. However, the mortality disparity between black and white women nationwide has continued to widen; and, by 2012, death rates were 42% higher in black women than in white women. During 2003 through 2012, breast cancer death rates declined for white women in all 50 states; but, for black women, declines occurred in 27 of 30 states that had sufficient data to analyze trends. In 3 states (Mississippi, Oklahoma, and Wisconsin), breast cancer death rates in black women were stable during 2003 through 2012. Widening racial disparities in breast cancer mortality are likely to continue, at least in the short term, in view of the increasing trends in breast cancer incidence rates in black women.
