High Incidence Of Breast Cancer Research Articles

Benchmarking Excellence: Evaluating Advanced Breast Carcinoma Care in Pakistan's Largest Cancer Hospital Against the National Institute for Health and Care Excellence (NICE) Guidelines.

Introduction Breast cancer is the most common type of cancer worldwide, and even with all the screening and education, great numbers of diagnoses are made in advanced stages. Additionally, patients in remission always remain at risk of relapse and metastasis. Pakistan has the highest incidence of breast cancer among Asian countries. The purpose of this clinical audit was to compare data from the largest cancer hospital in Pakistan with international standards to provide room for quality improvement. Methods A retrospective review of patients with advanced breast carcinoma over a period of six months was done. Permission was obtained from the Quality Assurance and Patent Safety Department before the commencement of the audit. Standards Data obtained were audited against nine standards of four different categories from the National Institute for Health and Care Excellence (NICE) guidelines on advanced breast carcinoma. Results For the diagnosis and assessment category, for which a target of 100% was set, 99.66% was achieved;for disease monitoring, for which a target of 100% was set, 91.8% was achieved; for systemic disease-modifying therapy, for which the majority was the target, only 1% was achieved; for managing complications, for which a target of 100% was set, 71.8% was achieved. Conclusion Continuous research and breakthrough advancements have made health care an ever-evolving field. Clinical audits like these that compare international standards with local dataare beneficial and lead to quality improvement. They highlight issues that may be overlooked otherwise, raise questions that may never be asked, and may inspire prospective research studies. Limitations of the audit were that this clinical audit was conducted outside of the NHS where NICE guidelines are not followed and local guidelines differ from NICE guidelines.

The burden of breast, cervical, and colon and rectum cancer in the Balkan countries, 1990–2019 and forecast to 2030

BackgroundDespite effective prevention and control strategies, in countries of the Balkan region, cancers are the second leading cause of mortality, closely following circulatory system diseases.ObjectiveTo describe trends in the burden of breast, cervical, and colon and rectum cancer in the Balkan region and per country between 1990 and 2019, including a forecast to 2030.MethodsWe described the 2019 Global Burden of Disease (GBD) estimates for breast, cervical, and colon and rectum cancers in eleven Balkan countries over the period 1990–2019, including incidence, years lived with disability (YLD), years of life lost (YLL), and disability-adjusted life years (DALYs) rates per 100,000 population and accompanied 95% uncertainty interval. With the Autoregressive Integrated Moving Average, we forecasted these rates per country up to 2030.ResultsIn the Balkan region, the highest incidence and DALYs rates in the study period were for colon and rectum, and breast cancers. Over the study period, the DALYs rates for breast cancer per 100,000 population were the highest in Serbia (reaching 670.84 in 2019) but the lowest in Albania (reaching 271.24 in 2019). In 2019, the highest incidence of breast cancer (85 /100,000) and highest YLD rate (64 /100,000) were observed in Greece. Romania had the highest incidence rates, YLD rates, DALY rates, and YLL rates of cervical cancer, with respective 20.59%, 23.39% 4.00%, and 3.47% increases for the 1990/2019 period, and the highest forecasted burden for cervical cancer in 2030. The highest incidence rates, YLD rates and DALY rates of colon and rectum cancers were continuously recorded in Croatia (an increase of 130.75%, 48.23%, and 63.28%, respectively), while the highest YLL rates were in Bulgaria (an increase of 63.85%). The YLL rates due to colon and rectum cancers are forecasted to progress by 2030 in all Balkan countries.ConclusionAs most of the DALYs burden for breast, cervical, and colon and rectum cancer is due to premature mortality, the numerous country-specific barriers to cancer early detection and quality and care continuum should be a public priority of multi-stakeholder collaboration in the Balkan region.

Evidence-based identification of breast cancer and associated ovarian and uterus cancer risk components in source waters from high incidence area in the Pearl River Basin, China

Breast cancer, ovarian cancer, and uterus cancer are among the most common female cancers. They are suspected to associate with exposures to specific environmental pollutants, which remain unidentified in source waters. In this work, we focused on the Pearl River Basin region in China, which experienced a high incidence of breast, ovarian, and uterus cancers. Combining cancer patient data, mammalian cell cytotoxicity analyses, and exhaustive historical and current chemical assessments, we for the first time identified source water components that promoted proliferation of mammalian cells, and confirmed their association with these female cancers via the estrogen receptor mediated pathway. Therefore, the components that have previously been found to enhance the proliferation of estrogen receptor-containing cells through endocrine disruption could be the crucial factor. Based on this, components that matched with this toxicological characteristic (i.e., estrogen-like effect) were further identified in source waters, including (1) organic components: phthalates, bisphenol A, nonylphenols, and per-/polyfluoroalkyls; (2) inorganic components: Sb, Co, As, and nitrate. Moreover, these identified water components were present at levels comparable to other regions with high female cancer prevalence, suggesting that the potential risk of these components may not be exclusive to the study region. Together, multiple levels of evidence suggested that long-term co-exposures to source water estrogenic components may be important to the development of breast, ovarian, and uterus cancers.

Parabens Promote Protumorigenic Effects in Luminal Breast Cancer Cell Lines With Diverse Genetic Ancestry.

One in 8 women will develop breast cancer in their lifetime. Yet, the burden of disease is greater in Black women. Black women have a 40% higher mortality rate than White women, and a higher incidence of breast cancer at age 40 and younger. While the underlying cause of this disparity is multifactorial, exposure to endocrine disrupting chemicals (EDCs) in hair and other personal care products has been associated with an increased risk of breast cancer. Parabens are known EDCs that are commonly used as preservatives in hair and other personal care products, and Black women are disproportionately exposed to products containing parabens. Studies have shown that parabens impact breast cancer cell proliferation, death, migration/invasion, and metabolism, as well as gene expression in vitro. However, these studies were conducted using cell lines of European ancestry; to date, no studies have utilized breast cancer cell lines of West African ancestry to examine the effects of parabens on breast cancer progression. Like breast cancer cell lines with European ancestry, we hypothesize that parabens promote protumorigenic effects in breast cancer cell lines of West African ancestry. Luminal breast cancer cell lines with West African ancestry (HCC1500) and European ancestry (MCF-7) were treated with biologically relevant doses of methylparaben, propylparaben, and butylparaben. Following treatment, estrogen receptor target gene expression and cell viability were examined. We observed altered estrogen receptor target gene expression and cell viability that was paraben and cell line specific. This study provides greater insight into the tumorigenic role of parabens in the progression of breast cancer in Black women.

Can We Still Afford Innovative Surgical Procedures?

Abstract Introduction Hospitals are currently facing major financial challenges. Due to the high incidence of breast cancer and the complex range of associated services, surgical treatment of breast cancer is a particular case in point when it comes to the question of cost coverage for innovative versus established procedures by the service providers. The aim of this study is to shed light from a healthcare economics perspective on the current situation of hospitals in Germany with regard to their different structures and processes for breast-conserving therapy. Materials and methods An online questionnaire with 46 questions was developed and made available to hospitals that are members of the AGO [German Working Group for Gynecological Oncology] Breast Committee and AWOgyn [German Working Group for Cosmetic, Plastic and Reconstructive Surgery in Gynecology], as well as AG-certified breast centers. The questions cover various parameters for health economics analysis, including primary case numbers, structures, and questions about tumor and sentinel marking and surgical procedures. Results 142 hospitals or breast centers took part in the survey. 93% of the hospitals were certified. The average number of primary cases was 264.6 per year. In over 60% of the hospitals, the surgical procedure and surgery planning were influenced by capacity limitations of cooperation partners. “Targeted axillary dissection” was performed in 83.5% of the hospitals, and radioactive markers were most commonly used for sentinel lymph node marking. Over 60% of participating hospitals were highly satisfied with the marking method used. Conclusion This structure and process analysis now makes it possible to reflect on the costs involved for hospitals of different sizes, in different regions, and with different funding models, and to use this as a basis for the economic evaluation of new surgical procedures within an overall context. In general, it is possible to make savings through innovative procedures in the surgical treatment of breast cancer.

Oridonin inhibits breast cancer cell proliferation and migrationthrough suppressing COX-2 expression

Oridonin, a biologically active substance isolated from the plant Rabdosia rubescens, is recently reported to have aninhibitory effect on breast cancer. However, its mechanism is still unclear. According to previous findings, increasedCOX-2 expression has been associated with a higher incidence of breast cancer. Therefore, this study aims to explorewhether oridonin inhibits cell proliferation and migration by suppressing the expression of COX-2 in human breastcancer cells MDA-MB-231 in vitro and in vivo conditions. In this study, human breast cancer cells MDA-MB-231will be treated with increasing concentrations and for various durations with oridonin to investigate whether oridonininhibits cell migration, decrease proliferation, and reduce tumors in mice through suppressing the expression of COX2. A positive control is a taxol. A negative control is medium. Cell migration will be tested by Transwell assay. Theproliferation will be detected by MTT assay. The western-blotting assay will be used for COX-2. In nude mice, the invivo anti-tumor efficacy of oridonin will be examined. The study’s result will provide insight into the effect of oridoninon the proliferation and migration of human breast cancer cells MDA-MB-231. It will also provide reference for themechanism of how oridonin inhibits breast cancer and lay the foundation for future studies on the molecular basis oforidonin’s pharmacological activity in the future.

Influence of radiation therapy on the development of complications in single-stage autologous breast reconstruction with a DIEP-flap in breast cancer patients: a retrospective study

Breast reconstruction after complex oncological treatment is an urgent issue due to the high incidence of breast cancer.
 Aim. To analyze the effect of postoperative radiotherapy on the incidence of fat necrosis in single-stage autologous breast reconstruction with a DIEP flap and to evaluate the number of complications in groups with and without postoperative radiotherapy, as well as to determine the risk factors for complications.
 Materials and methods. The medical records of 34 breast cancer patients who underwent one-stage breast reconstruction using a DIEP flap after skin-sparing/subcutaneous mastectomy with and without subsequent radiation therapy were retrospectively studied. The frequency of complications in groups with and without postoperative radiation therapy was assessed.
 Results. Complications developed in 22 (64.7%) patients out of 34. Mild complications developed in 6 (17.6%) patients (divergence of the edges of the postoperative wound of the anterior abdominal wall). Complications of moderate severity developed in 12 (35.3%) patients. Severe complications developed in 4 (11.8%) patients. Out of 22 patients, 6 (17.4%) patients developed areas of fat necrosis after remote radiation therapy in the delayed period, 4 (11.8%) patients, without ESWL, also developed fat necrosis of a part of the flap (areas up to 5 cm). Excision of the area of fat necrosis of the flap was performed in 2 (5.9%) cases under local anesthesia, the rest of the areas of fat necrosis were not excised. The percentage of complications was higher in the group of patients with obesity (20.6%), which indicates that obesity is a risk factor for the development of intraoperative and postoperative complications in patients with simultaneous breast reconstruction with a DIEP flap.
 Conclusion. During radiotherapy after breast reconstruction with a DIEP flap, the incidence of fat necrosis of the flap was higher. Obesity is a risk of intraoperative and postoperative complications in patients with simultaneous increased breast reconstruction with a DIEP flap, since the incidence of complications was in the group of patients with obesity.

Hereditary Diffuse Gastric Cancer

Hereditary diffuse gastric cancer (HDGC) is a dominantly inherited cancer syndrome characterized by a high incidence of diffuse gastric cancer (DGC) and lobular breast cancer (LBC). HDGC is caused by germline mutations in 2 genes involved in the epithelial adherens junction complex, CDH1 and CTNNA1. We discuss the genetics of HDGC and the variability of its clinical phenotype, in particular the variable penetrance of advanced DGC and LBC, both within and between families. We review the pathology of the disease, the mechanism of tumor initiation, and its natural history. Finally, we describe current best practice for the clinical management of HDGC, including emerging genetic testing criteria for the identification of new families, methods for endoscopic surveillance, the complications associated with prophylactic surgery, postoperative quality of life, and the emerging field of HDGC chemoprevention.

Estradiol Levels and Chemotherapy in Breast Cancer Patients: A Prospective Clinical Study.

Breast cancer remains a global health issue, including in Indonesia, which has a relatively high incidence of breast cancer. Several theories have proved the role of estrogen in breast cancer carcinogenesis, but there is yet to be a preventive measure against breast cancer. Chemotherapy is one of the therapeutic modalities for breast cancer that disturbs ovarian function in producing estrogen due to damaged ovarian granulosa cells. Chemotherapy becomes an alternative option to decreasing circulating estradiol levels through interventions in ovarian functions, either by surgery, such as oophorectomy, or medications that disturb the ovarian functions. This study aimed to observe the estradiol levels in breast cancer patients before and after chemotherapy. This was a prospective cohort study. We observed the estradiol levels before and after adjuvant chemotherapy in breast cancer patients. Subjects' characteristics are presented in mean ± standard deviation, distribution frequency, and percentage. Subjects' characteristics based on chemotherapy were tested using an independent t-test, Mann-Whitney U, and Chi-square/Fisher exact test. Effects of chemotherapy on estrogen levels were tested using the Wilcoxon rank test and Kruskal-Wallis test. A total of 194 research subjects were included. There were changes in estradiol levels before and after therapy. The decrease of estradiol levels in patients who did not receive chemotherapy was -6.9% (P > 0.05). Patients who received anthracycline cyclophosphamide (AC) regimen, paclitaxel and anthracycline (TA) regimen, paclitaxel, anthracycline and trastuzumab (TA + H) regimen, and platinum regimen experienced a significant decrease in estradiol levels (-21.4% (P < 0.05), -20.2% (P < 0.001), -31.7% (P < 0.01), and -23.7% (P < 0.05), respectively). Among chemotherapy groups, the estradiol levels before and after chemotherapy did not have significant differences (P = 0.937 and P = 0.730, respectively). There are no significant differences in estradiol levels between chemotherapy and hormonal therapy groups. Patients in both groups have decreased estradiol levels after therapy, although patients in hormonal therapy do not experience as much decrease as those in chemotherapy.

Pencegahan Kanker Payudara melalui Edukasi Kesehatan SADARI pada Siswi Madrasah Aliyah Qamarul Huda

Breast cancer is the highest cause of death for women in Indonesia. The number of deaths from breast cancer reached more than 22 thousand cases or 16.6% of 68,858 cases. The high incidence of breast cancer in women is caused by the lack of early health education. Therefore, this community service aims to increase student's knowledge about the early detection of breast cancer through BSE health education as a promotive and preventive effort. The target of this community service is 29 students at Islamic Senior High School Qamarul Huda. Health education media is used in the form of leaflets. This community service is an innovative health education that ends with a discussion and question and answer process for the students. Based on the results of the evaluation, it was found that the knowledge of students increased after BSE health education with an average knowledge level of 70.90 to 86.76 which means that the level of knowledge of students became good. This has a positive impact on aspects of knowledge and attitudes of students in carrying out early detection of breast cancer. Therefore, this community service is beneficial for students at Islamic Senior High School Qamarul Huda

The Women's Health Initiative randomized trials of menopausal hormone therapy and breast cancer: findings in context.

The menopausal hormone therapy (MHT) association with breast cancer has been controversial for more than 40 years. Most recently, findings from cohort studies have been discordant compared with those from the Women's Health Initiative (WHI) randomized trials. In cohort studies, both estrogen therapy and estrogen plus progestin were associated with higher breast cancer incidence. In contrast, in the WHI randomized trials, findings for estrogen plus progestin are concordant with cohort study reports, whereas estrogen therapy significantly reduced breast cancer incidence. In addition, concerns have been raised regarding the WHI findings from both trials. In this report, we briefly summarize findings for MHT on breast cancer from cohort studies and the WHI randomized trials. The report focus is addressing, point-by-point, concerns raised regarding the WHI findings. For cohort studies, we relied on the latest findings from (1) the meta-analysis of the Collaborative Group on Hormonal Factors in Breast Cancer and (2) the Million Women's Study. To identify commentaries and editorials, "Menopause" and "Climacteric" were searched from 2002 to present; PubMed and Google Scholar were searched for commentaries, editorials, and breast cancer, MHT, estrogen, conjugated equine estrogen, estradiol, "hormone replacement therapy," and "HRT." Thirty commentaries challenging WHI findings were identified. All were reviewed, and issues needing response were identified. Findings from the meta-analysis from the Collaborative Group on Hormonal Factors in Breast Cancer and the Million Women Study were summarized and compared with finding in the two WHI randomized trials evaluating estrogen therapy and estrogen plus progestin. Based on the randomized clinical trials, estrogen therapy, for women with prior hysterectomy, decreases breast cancer incidence and mortality. In contrast, estrogen plus progestin increases breast cancer incidence, which persists through two decades. Women considering estrogen plus progestin use for vasomotor symptoms should understand the breast cancer risk.

PI3K–AKT-Targeting Breast Cancer Treatments: Natural Products and Synthetic Compounds

Breast cancer is the most commonly diagnosed cancer in women. The high incidence of breast cancer, which is continuing to rise, makes treatment a significant challenge. The PI3K-AKT pathway and its downstream targets influence various cellular processes. In recent years, mounting evidence has shown that natural products and synthetic drugs targeting PI3K-AKT signaling have the potential to treat breast cancer. In this review, we discuss the role of the PI3K-AKT signaling pathway in the occurrence and development of breast cancer and highlight PI3K-AKT-targeting natural products and drugs in clinical trials for the treatment of breast cancer.

Screening Strategies for the Detection of Breast Cancer: Correlating Knowledge and Practice of Women in Eastern Saudi Arabia

Background and Aims: Breast cancer is the most common cancer worldwide. It represents 30.1% of other diagnosed female cancers as per the cancer incidence report of Saudi Arabia (2015). The highest incidence of breast cancer was observed in the eastern province region. Breast self-examination (BSE) and mammograms are helpful to detect breast cancer at the earliest. This study aimed to determine the knowledge and practices of women about breast cancer screening. Methods: A cross-sectional study was conducted to assess the knowledge and practices of women attending primary healthcare centers (PHC) in eastern Saudi Arabia regarding breast cancer screening. Data was collected from women who were aged 20 years and above through direct interviews using a validated questionnaire and it was analyzed using SPSS. Frequency distributions and chi-square tests were used to describe the demographic data and associate the variables respectively, with (p&lt;0.05) normality. Results: Out of 428 women, 62% were 41-60 years old, and most of them (84%) were married. Around 29% were unaware of breast cancer screening, 72% of women never did BSE, and 86% reported that they never had a mammogram. There was a significant association found between knowledge and age and education (p &lt; 0.05). A positive correlation was found between knowledge of BSE and mammogram (p &lt; 0.05). Conclusions: Even with the provision of free health services in Saudi, the practice of breast cancer screening was unsatisfactory. This alarm the focus to make awareness campaigns. The importance of early detection of breast cancer must be emphasized in every PHC centers continually.

Abstract C090: Associations between neighborhood green space and breast cancer outcomes among Philadelphia neighborhoods

Abstract Access to green space has been shown to be associated with decreased incidence of cancer. The goal of this study is to identify associations between neighborhood green space indicators and breast cancer outcomes at the neighborhood level in Philadelphia. Green space indicators were sourced from the National Land Cover Database (2006-2016), VT Spatial Analysis Lab (2008-2013) and Philadelphia Parks and Recreation (2016), and included average percent tree cover, average tree canopy, average low vegetation, count of public parks, and percent vacant lots. Breast cancer data from the PA Cancer Registry (2005-2014) included standardized incidence ratio (SIR), standardized mortality ratio (SMR), and mean aggressiveness (MA) of cancer. Neighborhood-level covariates were gathered from U.S. Census (American Communities Survey, 2008-2012) and the Public Health Management Corporation’s Household Health Survey (2012) for Philadelphia neighborhoods. Pearson correlations were calculated to identify associations between environmental and green space indicators and breast cancer outcomes. Multivariable linear regression was used to identify if significant relationships persisted in the presence of demographic and socioeconomic disparities at the neighborhood level. Significance was determined at p-values &amp;lt; 0.05. SIR was significantly correlated with % of vacant lots (r=-.186), % of tree canopy cover within 50 meters from neighborhood centroid (r=.139) and the number of public parks (r=.125) per neighborhood. SMR was significantly correlated with vacant lots (r=.184) and tree canopy cover (r=-.104). MA was significantly correlated with tree canopy (r=-.124), tree canopy within fifty meters of neighborhood centroid (r=-.146), number of public parks (r=-.141), and % of vacant lots (r=.157). After controlling for covariates in multivariable linear regression models, the significant relationships between neighborhood green space indicators and breast cancer outcomes were no longer significant. For SIR, the significant associations with green space indicators suggest that Philadelphia neighborhoods with a higher incidence of breast cancer have more green space and a lower % of vacant lots. For SMR and MA, associations suggest that neighborhoods with higher breast cancer mortality and aggressiveness have less green space and a higher % of vacant lots. The direction of these relationships makes sense, given the % and quality of neighborhood green space correlate closely with indicators of socioeconomic status. The lack of significance when controlling for confounders likely represents the limitations of using neighborhood-level data, rather than patient-level data, to measure the impact of green space on breast cancer outcomes. Future studies should identify green space exposure indicators at the individual level in order to more accurately identify the impact of urban green space on breast cancer outcomes. These data could inform city planning to decrease the burden of breast cancer among vulnerable populations. Citation Format: Benjamin C. Keating, Joseph Lombardo, Charnita Zeigler-Johnson, Alex M.

Association of BMI with Breast Cancer: An Experience at a Tertiary Healthcare in a Developing Country

Objective: Breast carcinoma is the most common invasive cancer in females, and second leading cause of global cancer mortality.1 The incidence of this disease remains high in our population. It is therefore essential to identify and control common risk factors. This case-control study was conducted to determine the relationship between BMI and breast cancer. Materials and Methods: A prospective case control study was performed between the time duration of September 2021 till February 2022. A total no of 158 patients, out of which 79 of them were part of the control group, while the remaining 79 had breast cancer were included in this study. Patient’s BMI and other risk factors were contrasted with these groups using stata 14.2. Results: Multivariate logistic regression analysis revealed that of the preoperative factors; age greater than 40 years(95%CI, 1.01 4.87), and postmenopausal status (95%CI, 1.10 9.70) were all independently associated with higher incidence of breast cancer in our women. BMI association with breast cancer was also considered significant with 95% confidence interval around 1 (95%CI, 0.20 1.14). Family history and breast cancer had no independent associated with each other. When only the tumor stage were compared, higher stage of disease was associated with delayed presentation. Conclusions: higher BMI, low parity and higher number of miscarriages cumulatively predispose the postmenopausal women of this region to higher risk of breast cancer.

The relationship of E-selectin singlenucleotide polymorphisms with breast cancer in Iraqi Arab women.

Breast cancer (BC) is a significant threat to female health, with both modifiable andnon-modifiable risk factors. It is essential to monitor patients regularly and to raise population awareness. Increasing research also suggests that E-selectin (SELE) may increase tumor angiogenesis and the development of cancer. This study investigated SELE single-nucleotide polymorphisms (SNPs) in the following positions: rs5367T/C, rs5368C/T, rs5362T/G,and rs5362T/C. Using polymerase chain reaction, significant differences in allele and genotype frequencies were found between BC patients and controls. Position rs5368 was associated with an increased risk of BC for the CT and TT genotypes, with odds ratios (ORs) of16.3 and 6.90 (Fisher probability = 0.0001, p = 0.005). Women with the T allele had a 19.3-fold higher incidence of BC, while allele C may be a protective allele against BC (OR, 0.05).Heterozygous genotypes at rs5367, rs5362, and rs5362 were significantly more common inBC patients, with ORs of 5.70, 4.50, and 3.80, respectively. These SNPs may be associatedwith the risk of BC, because the frequency of mutant alleles was significantly higher in patients (OR: 4.26, 3.83, and 4.30, respectively) than in controls (OR: 0.23, 0.30, and 0.20, respectively). These SNPs may be considered a common genotype in the Iraqi population,with the wild-type allele having a protective fraction and the mutant allele having an environmental fraction. The results also revealed a 2-fold increase in gene expression in BCpatients compared to controls, with a significant effect (p = 0.017). This study's findingsconfirm the importance of SELE polymorphisms in cancer risk prediction.

Early Detection Program for Breast and Cervical Cancer in Indonesia: How is Implementation?

Breast and cervical cancer have ranked first and second in terms of the highest cancer cases in Indonesia. The high incidence of breast and cervical cancer is due to the low coverage of early detection. This study aimed to examine the implementation of breast cancer early detection programs using the SADANIS method and cervical cancer using the IVA method. This current study used a qualitative and descriptive approach through input, process, output, and impact variables. Data was collected through in-depth interviews, observation, and documentation review. The results revealed that the number of trained human resources, facilities, and infrastructure was sufficient. The program had also implemented online and offline information systems and was actively conducting inspections integrated with the “Family Planning” program. The high achievement of the program had also been supported by the existence of an innovative screening system and direct examination in the community. The program achievements for 2021-2022 (January-June) and cases of cervical cancer had decreased. Implementing the early detection program for breast and cervical cancer is considered better. It can thus become a model for other regencies.&#x0D;

Could the high incidence of breast cancers in Nigerian women be related to 1,4-Dioxane in skin lightening products?

Two monstrous female health-related issues are currently engaging the attention of the global community. These are the chemical skin-lightening issue and the rising female breast cancer issue. Nigeria has the highest prevalence of chemical skin lightening practice with 77.3% of traders in Lagos using such products and one of the highest incidences of breast cancer globally of 50.5 per 100,000 women. 1,4-Dioxane, a possible contaminant in toiletries and cosmetics, is an IARC group 2B carcinogen and a potential breast carcinogen. It is generated when ethylene oxide -a known breast carcinogen is added to other chemicals during manufacturing. The skin lightening procedure is most conducive for optimal per-cutaneous absorption and inhalation of Dioxane. The research question entertained was if there is a link in the increasing prevalence of skin lightening practice and the rising breast cancer burden in Nigeria. One hundred skin lightening products procured from across Lagos, Nigeria had their listed contents scrutinized and entered onto a spreadsheet, then they were analyzed for Dioxane using Scalia’s Solid Phase Extraction gas chromatography procedure. Water (Aqua) 66%, Glycerin 60% and Tocopherol or Vitamin E 41% were found to be the most listed ingredients on the package labels, with Vitamin C 28%, Kojic acid 26%, Citric acid 22% and Carrot oil seen in 20% of products. All the analyzed samples were negative for Dioxane. The study brought to the fore the need to explore other potential breast carcinogens in skin lightening cosmetics and environmental chemicals.

Breast Cancer Is Significantly Associated with Cancers in The First- and Second-Degree Relatives in Ethnic Mizo-Mongoloid Population, Northeast India

Background: High incidence of breast cancer among the endogamous Mizo-Mongoloid tribe stresses the need to explore the disease pertaining to the family history as well as other risk factors. This study investigates the association of risk factors and inherited diseases with breast cancer. Methodology: The study includes 426 unrelated breast cancer cases and 810 healthy controls of female Mizo ethnicity. Association between reproductive history, lifestyle/ dietary habits, tobacco and alcohol exposures, family history in relation to cancer and inheritable diseases was assessed by univariate logistic regression using Chi-square tests and multivariate analyses using Cox regression. Results: Age at diagnosis was highest between 41 to 50 years. Consumption of fermented pork fat, smoked food and Smoke-less tobacco, lower intake of vegetables/ water, having a first/ or second degree relative with cancers and inheritable diseases were found to be the major risk factors. Certain known factors were also acting as confounding factors. Conclusions: The present study reveals that Mizo women with first- and second-degree relatives of breast cancer, various other cancers and inheritable diseases have increased risk of breast cancer. This study also highlights the importance of analysing genetic factors which can aid in early detection of inherited risk factors.

HER2-Displaying M13 Bacteriophages induce Therapeutic Immunity against Breast Cancer.

Simple SummaryThe high incidence and death rates of breast cancer make the development of new therapies an urgent need. The introduction into the clinic of the anti-HER2 monoclonal antibody trastuzumab considerably improved the overall survival and time-to-disease progression of patients with HER2-positive breast cancer. However, many patients do not benefit from it because of resistance to therapy. Cancer vaccines, by inducing into the patient an anti-cancer specific immunity, might represent an alternative immunotherapeutic approach, but despite promises, so far no anti-HER2 cancer vaccine has been approved for human use. In this study, we propose therapeutic phage-based vaccines, against HER2 and its aggressive isoform Δ16HER2, able to elicit a protective immunity and potentially capable of preventing relapse in HER2-positive breast cancer patients, even in those who develop trastuzumab resistance.The advent of trastuzumab has significantly improved the prognosis of HER2-positive (HER2+) breast cancer patients; nevertheless, drug resistance limits its clinical benefit. Anti-HER2 active immunotherapy represents an attractive alternative strategy, but effective immunization needs to overcome the patient’s immune tolerance against the self-HER2. Phage display technology, taking advantage of phage intrinsic immunogenicity, permits one to generate effective cancer vaccines able to break immune tolerance to self-antigens. In this study, we demonstrate that both preventive and therapeutic vaccination with M13 bacteriophages, displaying the extracellular (EC) and transmembrane (TM) domains of human HER2 or its Δ16HER2 splice variant on their surface (ECTM and Δ16ECTM phages), delayed mammary tumor onset and reduced tumor growth rate and multiplicity in ∆16HER2 transgenic mice, which are tolerant to human ∆16HER2. This antitumor protection correlated with anti-HER2 antibody production. The molecular mechanisms underlying the anticancer effect of vaccine-elicited anti-HER2 antibodies were analyzed in vitro against BT-474 human breast cancer cells, sensitive or resistant to trastuzumab. Immunoglobulins (IgG) purified from immune sera reduced cell viability mainly by impairing ERK phosphorylation and reactivating retinoblastoma protein function in both trastuzumab-sensitive and -resistant BT-474 cells. In conclusion, we demonstrated that phage-based HER2 vaccines impair mammary cancer onset and progression, opening new perspectives for HER2+ breast cancer treatment.
