SATB1在南疆维汉妇女宫颈病变组织中的表达及意义

目的:探讨南疆维吾尔族与汉族妇女宫颈病变组织中SATB1的表达及其意义。方法:采用免疫组化法检测300例(150例维吾尔族、150例汉族)妇女宫颈癌组织、宫颈上皮内瘤样病变组织(cervical intraepithelial neoplasias,CIN)、慢性宫颈炎组织中特异AT序列结合蛋白1(special AT-rich sequence binding protein,SATB1)的表达。结果:不同程度宫颈病变组之间SATB1的表达差异有统计学意义(P=0.00),CINⅠ组与慢性宫颈炎组表达差异无统计学意义(P=0.38)。SATB1在维汉族妇女宫颈病变组织中的表达差异无统计学意义(P=0.69)。结论:SATB1的表达不存在维汉民族差异性,表明在南疆维吾尔族和汉族宫颈癌的发生、发展中SATB1的表达具有共同性,无民族间基因背景差异。SATB1在宫颈癌组织中的表达高于宫颈上皮内瘤样病变组织、慢性宫颈炎组织,提示SATB1的表达与宫颈病变及其癌变的发生发展关系密切,如进一步研究可能对宫颈癌的治疗提供理论依据。     

人类白细胞抗原Ⅰ在新疆维吾尔族和汉族宫颈病变患者中的表达差异

目的:探讨人类白细胞抗原-Ⅰ(human leukocyte antigen-Ⅰ,HLA-Ⅰ)在新疆维吾尔族和汉族宫颈病变患者中的表达差异。方法:应用免疫组织化学法检测新疆维吾尔族和汉族妇女慢性宫颈炎、宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)和宫颈鳞状细胞癌(cervical squamous cell carcinoma,CSCC)组织中HLA-Ⅰ蛋白的表达水平。结果:在慢性宫颈炎、CIN和CSCC组织中,HLA-Ⅰ蛋白的表达水平呈现正常表达、部分缺失和完全缺失的转变。慢性宫颈炎组织中HLA-Ⅰ蛋白表达的完全缺失率为2%(1/49),CIN组织中HLA-Ⅰ蛋白表达的完全缺失率为26%(29/113),CSCC组织中HLA-Ⅰ蛋白表达的完全缺失率为49%(34/70),各组间差异有统计学意义(P<0.05)。新疆维吾尔族和汉族宫颈病变组织中HLA-Ⅰ蛋白表达的完全缺失率的上升趋势较一致,但是维吾尔族妇女CIN和CSCC组织中的完全缺失率(27%和53%)高于汉族妇女(18%和37%)。结论:HLA-Ⅰ蛋白表达缺失可能是宫颈癌发病进程的重要标志,其族群差异可能反映不同族群的遗传背景及肿瘤发病机制。     

维吾尔族妇女宫颈癌发生与EBV及HPV感染的关系

目的:探讨维吾尔族妇女宫颈癌发生过程中EB病毒(Ebstein-Barr virus,EBV)及人乳头瘤病毒(human papillomavirus,HPV)感染的作用及其意义。方法:收集维吾尔族妇女宫颈炎、宫颈内上皮瘤样病变(cervical intraepithelial neoplasja,CIN)Ⅰ/Ⅱ/Ⅲ和宫颈鳞癌患者福尔马林浸泡与石蜡包埋组织标本共178例,提取DNA并采用PCR方法对EBV和HPV DNA进行检测;用免疫组织化学方法检测宫颈癌EBV蛋白表达。结果:病毒DNA检测结果显示,宫颈炎、CINⅠ、CINⅡ～Ⅲ和宫颈癌患者各组HPVDNA检出率依次足2.5%、12.5%、68.0%、96.4%,EBV DNA为0、3.1%、28.0%和69.6%,其中宫颈炎组与CINⅡ～Ⅲ和宫颈癌组问的差异具有统计学意义(P均0.05),但宫颈炎与CINI组间的差异无统计学意义(P0.05)。宫颈病变病理进程不仅伴随着HPV及EBVDNA阳性检出率梯度上升,而且与HPV和EBV双重感染检出率增高呈正相关(r=0.46,X~2=82.50,P0.001)。对宫颈癌组织进行免疫组织化学分析,发现EBV DNA检测阳性标本中EBV蛋白阳性表达检出率为89.7%(34/39),而阴性标本中蛋白表达阳性率为6%(1/17)。结论:维吾尔族妇女宫颈癌的发生与发展可能与HPV和EBV双重感染密切相关。

Women Like Me

Abstract

Hormone replacement therapy (HRT) traditionally has been withheld from women with breast cancer to minimize their risk of recurrence. However, the benefits of HRT include relief from menopausal symptoms and protection against osteoporosis and possibly heart disease. Focus groups were conducted among women diagnosed with breast cancer to explore how the women approached health decisions, especially regarding HRT, and to identify factors that influenced their decision-making process. Factors identified included relief of symptoms, fear of cancer, side effects of treatment, attitudes toward risk, perception of risk and mastery, and physicians' recommendations. The article discusses these factors and provides suggestions, such as the following, to care providers who counsel women concerning menopause and HRT: Help patients understand areas in which the evidence is solid, address their possibly unrealistic expectations, and help them articulate their feelings and fears.     

What Women Think: Cancer Causal Attributions in a Diverse Sample of Women

Women hold diverse beliefs about cancer etiology, potentially affecting their use of cancer preventive behaviors. Research has primarily focused on cancer causal attributions survivors and participants from non-diverse backgrounds hold. Less is known about attributions held by women with and without a family history of cancer from a diverse community sample. Participants reported factors they believed cause cancer. Open-ended responses were coded and relations between the top causal attributions and key factors were explored. Findings suggest certain socio-cultural factors play a role in the causal attributions women make about cancer, which can, in turn, inform cancer awareness and prevention messages.     

Effective Surveillance of High-Risk Women

BackgroundThis study addresses the effectiveness of risk models and screening breast magnetic resonance imaging (MRI) in women who have atypical hyperplasia (AH), lobular carcinoma in situ (LCIS), or a family history of breast cancer, but not a genetic mutation.Patients and MethodsA retrospective review of 444 women who had 458 breast screening MRIs at a community teaching hospital over a 12-month period between March 25, 2014 and March 31, 2015 was performed. The patients underwent high risk screening with breast MRIs alternating with mammograms every 6 months. After excluding patients with prior breast or ovarian cancer, genetic mutations, and chest wall radiation, 200 remaining patients constituted the study cohort. Over the following 5 years, the patients were screened with MRIs alternating with mammograms every 6 months. A total of 961 total MRI screenings were performed over the entire 5-year period of the study.ResultsA total of 200 women fit the study criteria. Of these 103 had a prior history of AH or LCIS. Over the 5-year period, 60 women dropped out of the screening regimen, 6 patients were diagnosed with breast cancer on screening MRIs, and 2 additional patients were diagnosed with breast cancer on screening mammograms. Surprisingly, the highest Tyrer-Cuzick (T-C) scores did not correlate with increased development of breast cancers in our population.ConclusionsThis study shows that there is wide variation in the results of risk assessment models. Risk models may overestimate breast cancer risk, suggesting that re-evaluation of current risk assessment and screening protocols is warranted.     

Profiles of Women with Breast Cancer

Abstract

The purpose of this paper is to discuss the profiles of women with breast cancer for whom a telephone interpersonal counseling intervention (TIP-C) was beneficial for symptom management and quality of life. This analysis was based on 24 participants who completed the telephone counseling intervention and all three measurements over the course of 10-week pilot study. The typical woman with breast cancer was white, in her mid-fifties and married at the time of the study. The majority was Stage II and was receiving chemotherapy as their primary adjuvant treatment. Preliminary findings suggest that women who were in long-term marriages and reported no previous history of depression or cancer benefited most from the intervention. These women reported less depression, negative affect, symptom distress and fatigue, and improved quality of life. Several theories are proposed for these findings and implications for practice are discussed.     

Lower Aortic Stenosis in Women

Four cases of marked lower aortic stenosis in women are recorded. Their age group was noted to be lower than in women with lower limb ischaemia from occlusion or stenosis of the lower limb arteries themselves. The similarity of the symptoms of lower aortic stenosis and complete aortic occlusion of slow onset is noted.     

Women in contemporary cancer research

Despite recent advances, gender inequality persists in many scientific fields including medicine. Thus far, no study has extensively analyzed the gender composition of contemporary researchers in the oncology field. We examined 40 oncological journals (Web of Science, Oncology category) with different impact factors (Q1–Q4) and extracted all the articles and reviews published during 2015–2017 in order to identify the gender of their authors. Our data showed that women represent about 38% of all the authorships, both in articles and reviews. In relative terms, women are overrepresented as first authors of articles (43.8%), and clearly underrepresented as last or senior authors (<30%). This double pattern, also observed in other medical fields, suggests that age, or more specifically, seniority, may play some role in the gender composition of cancer researchers. Examining the pattern of collaboration, an interesting finding was observed: the articles signed by a woman in the first or in the last position roughly showed gender parity in the byline. We also found some differences in the content of the articles depending on which gender occupies the first and last positions of the authorships.
