Residential surrounding greenness is not associated with incident breast cancer in young women in Ontario, Canada

ObjectivesEnvironmental exposures play an important role in the development of breast cancer. The incidence of breast cancer is increasing in young women, and its etiology differs from that of older women. Epidemiological studies have provided mixed evidence about whether proximity to urban greenness reduces the risk of breast cancer, but few studies have evaluated this risk in younger women.MethodsWe investigated associations between residentially-based measures of greenness and breast cancer among participants of the Ontario Environmental Health Study (OEHS). The OEHS was a case–control study of Ontario women, 18–45 years of age, who provided questionnaire data between 2013 and 2015. The study included 465 cases diagnosed with a pathologically confirmed primary diagnosis of breast cancer, and 242 population-based controls. Residentially-based measures of greenness, the Normalized Difference Vegetation Index (NDVI) and tree coverage percentage, at 100-, 250-, 500-, and 1,000-m buffers, were assigned to the residential histories of the women. Odds ratios and their 95% confidence intervals (CIs) were estimated using logistic regression, adjusted for potential confounders including traffic-related air pollution [nitrogen dioxide (NO2)].ResultsWe found no evidence that an increase in NDVI or tree coverage were significantly associated with breast cancer. The adjusted odds ratio of breast cancer in relation to an interquartile range increase (IQR) in the NDVI (500-m buffer) was 0.86 (95% CI = 0.59–1.13). Similarly, the odds ratio of breast cancer among those in the highest quartile of tree coverage (500-m buffer) relative to the lowest was 1.11 (95% CI = 0.59–2.07). Risk estimates for both measures of greenness did not vary substantially across different buffer distances. Exposure to NO2 was an important confounder in these associations.ConclusionsOur findings do not support the hypothesis that residential greenness reduces the risk of breast cancer among young women, while highlighting the importance of adjusting for air pollution.

Breast Cancer in Young Women: Is It Different? A Single-Center Retrospective Cohort Study.

Breast cancer (BC) is one of the commonest cancers among women worldwide. Differences regarding tumor biology, presentation, genetics, and molecular subtypes may contribute to the relatively poorer prognosis among younger women. Limited information exists regarding pathologic characteristics and long-term outcomes among this group. This retrospective cohort study included 695 BC patients diagnosed over a 10-year period and investigated the clinicopathological characteristics and long-term disease outcomes among patients diagnosed at age less than or equal to 40 years compared with older ones. Cox regression analysis was performed, and Kaplan-Meier curves were generated to assess overall survival (OS). Compared with the younger patients (⩽40 years) estrogen receptor (ER) and progesterone receptor (PR) expression was mainly positive in older patients (>40 years) (76.2% vs 61.3% and 64.2% vs 49.6%, respectively). The most common molecular subtype in both age groups was luminal B (44.1% in older and 40.3% in younger). A clinical complete remission after neoadjuvant therapy was observed more frequently in older patients (76.7%; N = 442) in comparison with the younger patients (66.4%; N = 79) (P = .018). Recurrence and disease progression were significantly more likely to occur among younger patients accounting for 12.6% and 29.4% of the cases, compared with 6.3% and 18.2% in older patients (P = .016 and P = .006, respectively). The overall mortality was 132 (19%) of 695, with 88% cancer-related deaths. Estrogen receptor and PR expression (P ⩽ .001 and P = .003, respectively), molecular subtype (P = .002), tumor grade (P = .002), and N stage (P = .038) were the variables that were found to be significantly influenced by age. The OS was not statistically different among 2 age groups, but younger patients with luminal A molecular subtype showed significantly poor outcome (P = .019). Overall survival in women diagnosed with BC at age less than or equal to 40 years is not significantly worse than older patients. However, among patients with luminal A subtype, younger women had relatively poor survival. Further research is needed to understand this age-based disparity in outcomes.

Fertility concerns and treatment decision-making among national sample of young women with breast cancer.

Diagnosis of breast cancer in young women has been shown to affect their decision-making with regard to fertility and family planning. Limited data are available from populations across the U.S. regarding this issue; thus, we sought to describe fertility concerns and efforts to preserve fertility in a national clinical trial population of young breast cancer patients. The young and strong study was a cluster-randomized controlled trial testing an intervention program for young women with breast cancer. Patients were surveyed within 3 months after diagnosis and at 3, 6, and 12 months after. Surveys asked about sociodemographics, psychosocial domains, fertility concerns, and fertility preservation strategies. Univariable and multivariable models were used to investigate sociodemographic, clinical, and psychosocial predictors of fertility concerns. Of 467 women from 54 clinical sites across the U.S. (14 academic, 40 community), 419 were evaluable regarding fertility concerns. Median age was 40 years (range 22-45), 11% were Black, 6% Hispanic, and 75% had children. Tumor stage was I (35%), II (51%), or III (14%); 82% received chemotherapy. At time of the treatment decision, 133 (32%) participants had fertility concerns, among whom 47% indicated this affected their treatment decisions. Sixty percent of participants reported having discussed fertility with their physician. Twenty percent of those with fertility concerns used fertility preservation strategies. History of difficulty becoming pregnant and younger age were associated with higher odds of fertility concerns in multivariable modeling. Many young women with newly diagnosed breast cancer are concerned about fertility in a way that impacts their treatment decisions. Concerns were discussed, but few used fertility preservation strategies. These findings have implications for counseling young patients.

Incidence and influencing factors of fertility concerns in breast cancer in young women: a systematic review and meta-analysis.

This systematic review and meta-analysis aimed to evaluate the prevalence and influencing factors of fertility concerns in breast cancer in young women. A literature search on PubMed, Embase, Web of Science, and Cochrane Library databases was conducted up to February 2023 and was analyzed (Revman 5.4 software) in this study. The papers were chosen based on inclusion standards, and two researchers independently extracted the data. The included studies' quality was evaluated using criteria set out by the Agency for Healthcare Research and Quality. To identify significant variations among the risk factors, odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were utilized. A total of 7 studies that included 1579 breast cancer in young women were enrolled in the study. The results showed that for breast cancer in young women, the incidence of fertility concerns 53%(95%CI [0.45,0.58]). The results showed that education (2.65, 95% CI 1.65-5.63), full-time work (0.12, 95% CI 1.03-1.93), fertility intentions (7.84, 95% CI 1.50-37.4), depression level (1.25, 95% CI 1.03-1.5), and endocrine therapy (1.32, 95% CI 1.08-1.62) were risk factors for fertility concerns in young women with BC. Having a partner (0.41, 95% CI 0.33-0.5), ≥1 child (0.3, 95% CI 0.22-0.4) were identified as protective factors against fertility concerns in young women with BC. The incidence of fertility concerns in breast cancer in young women is at a moderately high level. We should pay more attention to the risk factors of fertility concerns to help breast cancer in young women cope with their fertility concerns and promote their psychological well-being.

Diagnostic delays in breast cancer among young women: An emphasis on healthcare providers

Despite advances in breast cancer care, breast cancer in young women (BCYW) faces unique challenges, diagnostic delays, and limited awareness in many countries. Here, we discuss the challenges and consequences associated with the delayed diagnosis of BCYW. The consequences of delayed diagnosis in young women - which generally varies among developed, developing, or underdeveloped countries - are severe due to a faster breast tumor growth rate than tumors in older women, also contributing to advanced cancer stages and poorer outcomes. Though there are many underlying reasons for diagnostic delays due to age, the article delves explicitly deep into the diagnostic delay of BCYW, focusing on healthcare providers, potential contributing factors, its consequences, and the urgent need to start minimizing such incidences. The article suggests several strategies to address these issues, including increasing awareness, developing educational programs for healthcare providers to identify signs and symptoms in young women, developing clear diagnostic guidelines, and improving screening strategies.

Content Quality of YouTube Videos About Metastatic Breast Cancer in Young Women: Systematic Assessment.

Young women with metastatic breast cancer (MBC) are part of a digitally connected generation yet are underserved in terms of information needs. YouTube is widely used to find and identify health information. The accessibility of health-related content on social media together with the rare and marginalized experiences of young women with MBC and the digital media practices of younger generations imply a considerable likelihood that young women with MBC will seek information and community on the internet. This study aims to assess the content quality of MBC YouTube videos and to identify themes in the experiences of young women with MBC based on YouTube videos. A systematic assessment of MBC YouTube videos using the search term "metastatic breast cancer young" was conducted in August 2021. The search was performed in an incognito browser and with no associated YouTube or Google account. Search results were placed in order from most to least views. Title, date uploaded, length, poster identity, number of likes, and number of comments were collected. Understandability and actionability were assessed using the Patient Education Materials Assessment Tool (PEMAT); information reliability and quality were assessed with DISCERN. Themes, sponsorships, and health care professionals' and patients' narratives were reported. A total of 101 videos were identified. Of these, 78.2% (n=79) included sponsorships. The mean PEMAT scores were 78.8% (SD 15.3%) and 43.1% (SD 45.2%) for understandability and actionability, respectively. The mean DISCERN score was 2.44 (SD 0.7) out of 5. Identified themes included treatment (n=67, 66.3%), family relationship (n=46, 45.5%), and motherhood (n=38, 37.6%). YouTube videos about young women with MBC are highly understandable but demonstrate moderate rates of actionability, with low reliability and quality scores. Many have a commercial bias. While web-based materials have limitations, their potential to provide patient support is not fully developed. By acknowledging their patients' media habits, health care professionals can further develop a trusting bond with their patients, provide a space for open and honest discussions of web-based materials, and avoid any potential instances of confusion caused by misleading, inaccurate, or false web-based materials.

SCIENTIFIC PRODUCTION ABOUT THE LATE DIAGNOSIS OF BREAST CANCER IN YOUNG WOMEN

The objective of this study is to: Analyze scientific productions on the diagnosis of breast cancer in young women. This study is of the bibliographic modality, with a qualitative, descriptive and exploratory approach. The bibliographic study occurs from a data survey, which uses some instruments, such as: books, scientific articles, theses, dissertations, legislation and other published sources. 10 scientific articles were used, unifying the descriptors and also the information found. Knowing that breast cancer is common in women over 50 years of age, as seen in the results found, there are studies that prove the increase in cases in young women, which raises awareness about this very important topic. In this way, many changes can occur in a woman’s life that lead to the occurrence in youth, and faced with so many demands, in addition to factors related to family, work, emotional, social and food activities, there is difficulty in diagnosing, making it late.

Metastasis, characteristic, and treatment of breast cancer in young women and older women: A study from the Surveillance, Epidemiology, and End Results registration database.

Younger age is an independent risk factor for breast cancer (BC) prognosis, and BC in young women is often considered more aggressive. BC patients with different age and molecular subtypes have different metastasis patterns and survival. Herein, we aim to explore the metastasis patterns, characteristics and treatment methods of young patients with BC, and to compare them with older patients. Data of young patients (aged ≤40 years old) and older patients (aged >40 years old) with BC were extracted from the Surveillance, Epidemiology, and End Results (SEER) registration database in 2010-2019 in this retrospective cohort study. Univariate and multivariate competing risk models and proportional hazard models were used to explore the association between different metastasis patterns and treatments and BC prognoses in young and older patients. Kaplan-Meier (KM) curves were drawn to reflect the survival probability of patients with BC who have different metastasis patterns. Also, we performed subgroup analysis of different metastasis patterns to explore the association between different treatments and overall survival (OS)/cancer specific survival (CSS) in patients with BC. The evaluation index was hazard ratios (HRs) with 95% confidence intervals (CIs). Totally, 5,984 patients died, and 92.56% of them died from BC. There were respectively 1,089 young patients and 9,105 older patients, and we found some differences of characteristics and metastasis patterns between them. After adjusting for covariates, young patients who had brain metastasis and multiple sites metastasis seemed to have high risk of both lower OS and CSS. Among older patients with BC, brain metastasis, liver metastasis, and multiple sites metastasis were all positively associated with both lower OS and CSS. In young and older patients, those who not receive radiotherapy or surgery, or received non-surgery combined with radiotherapy seemed to have high risk of both lower OS and CSS. Breast-conserving surgery (BCS) and surgery combined with radiotherapy were associated with higher OS and CSS in young patients, while only older patients received surgery combined with radiotherapy had higher OS and CSS. Results of subgroup analysis indicated that for patients with different metastasis patterns, developing a personalized treatment plan is necessary. Characteristics of BC between young patients and older patients were different. Clinicians should focus on different metastasis sites and choose appropriate treatments in patients with different ages, which may improve the prognoses.

Diagnostic delay among young women with breast cancer.

117 Background: Breast cancer in women under 40 is uncommon, but often presents with greater disease burden and worse survival compared to the post-menopausal population. Given its infrequence, it is not well-understood how young patients initiate contact with care and how they are investigated prior to establishing the diagnosis. Whether young women experience diagnostic delay and whether it might impact survival is unclear. We aimed to describe the presentation of breast cancer among women <40 and to understand the diagnostic timeline using patient-reported outcomes. Methods: We evaluated patients in the Reducing the Burden of Breast Cancer in Young Women (RUBY) cohort, a pan-Canadian study recruiting women <40 with breast cancer at the time of diagnosis. Five online surveys detailing demographics, medical/family history and the diagnostic journey, distributed by e-mail at the time of recruitment, were used. All subjects who completed the surveys from 2015-2022 were included. A “patient delay” was considered >4 weeks from onset of symptoms to first contact with the healthcare system. A “system delay” was considered >3 weeks from presentation to first investigation, based on Canadian Partnership Against Cancer screening guidelines. Analysis was conducted using descriptive statistics. Results: There were 1148 patients included for analysis. Median age (IQR) was 37 (33.9, 39.0). Eighty-nine percent of patients had a symptom prompting assessment, of which most had a palpable mass (77.3%), and 27.7% had a painful mass. The median (IQR) number of weeks that patients waited was 2.0 (1.0, 8.0), and 364 patients (31.7%) experienced a patient delay. Most patient delays were attributed to lack of awareness of associated symptoms: 27.7% of patients were not concerned about their symptom and 3.9% were falsely reassured by practitioners. Other reasons included difficulty accessing timely care (3.6%; 37 patients) and conflicting priorities (2.1%; 21 patients). One hundred sixteen patients (10.1%) experienced a system delay. When asked about perceived timeliness of diagnosis, only 248 patients (24.4%) felt their time to assessment was not fast enough. Conclusions: The majority of young women with breast cancer present with palpable, often painful masses. A significant proportion of women experienced a patient delay, suggesting opportunities for increased education regarding presentation of early-onset breast cancer; After presentation to care, most women were investigated in a timely manner.

How reliable are post-mastectomy breast reconstruction videos on YouTube?

305 Background: Social media are a significant source of information for young women with breast cancer (YWBC) undergoing post-mastectomy breast reconstruction (PMBR). The emphasis on visual storytelling and building community in online spaces renders YouTube (YT) to be a common platform for discussions of BR. This study aims to assess the quality of YT videos about PMBR, identify themes related to the PMBR experience, and quantify perceptions of BR as an option PM. Methods: YT was searched incognito with terms “young women breast cancer reconstruction” in 08/2022, in order from most to least viewed. Title, upload date, length, poster identity, number of likes and comments were collected. The Patient Education Materials Assessment Tool for audiovisual materials (PEMAT A/V) was used to evaluate understandability and actionability. DISCERN assessed quality and reliability. Presence of sponsorship, intended audience, patient and healthcare professional narratives, and perceptions of PMBR were collected. Reviewers noted whether PMBR was shown and how. Themes were collected inductively and deductively for thematic analysis. Results: 193 videos were identified. Mean video length was 14.6 minutes (SD 20.0 min). 87.1% included sponsorships. 95.9% of videos were posted by an organization. 60.6% were information-based; 45.6% experience-based. Mean PEMAT scores for understandability and actionability were 71.3% (SD 13.4) and 35.7% (SD 41.8), respectively. Mean DISCERN was 2.6/5 (SD 1.2). Patient narrative was present in 52.6% and healthcare professionals’ in 68.4%. PMBR was visually presented 22.8% of the time. 13.5% of videos explicitly recommended PMBR. 2.6% explicitly discouraged it. Patients (77.7%) are the majority of the intended audience. Most common deductively identified themes included treatment (87.1%), family relationship (17.1%), motherhood ( 15.5%), fertility (11.9%). Inductively identified subthemes included differentiating between various options for PMBR surgery, BRCA genetic testing, psychosocial effects of breast cancer and PMBR, and recovery from surgery. Conclusions: YT is a platform wherein various PMBR options are widely discussed and explained. PMBR videos are highly understandable but have moderate levels of actionability, quality, and reliability. Videos are highly sponsored, demonstrating significant institutional bias. Themes are overwhelmingly treatment and surgery-based. Personal themes were present but not dominant.[Table: see text]

Safety of pregnancy after breast cancer in young women with hormone receptor-positive disease: a systematic review and meta-analysis

Despite increasing evidence on the safety of pregnancy after anticancer treatments in breast cancer survivors, many physicians and patients remain concerned about a potential risk of pregnancy specifically in the case of hormone receptor-positive breast cancer. A systematic literature search of Medline, Embase and Cochrane library with no language or date restriction up to 31 March 2023 was carried out. To be included, articles had to be retrospective and prospective case-control and cohort studies as well as clinical trials comparing survival outcomes of premenopausal women with or without a pregnancy after prior diagnosis of hormone receptor-positive breast cancer. Disease-free survival (DFS) and overall survival (OS) were the outcomes of interest. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated. Study protocol is registered in PROSPERO (n. CRD42023394232). Out of 7796 screened studies, 8 were eligible to be included in the final analysis. A total of 3805 patients with hormone receptor-positive invasive early breast cancer were included in these studies, of whom 1285 had a pregnancy after breast cancer diagnosis. Median follow-up time ranged from 3.8 to 15.8 years and was similar in the pregnancy and non-pregnancy cohorts. In three studies (n= 987 patients) reporting on DFS, no difference was observed between patients with and those without a subsequent pregnancy (HR 0.96, 95% CI 0.75-1.24, P= 0.781). In the six studies (n= 3504 patients) reporting on OS, patients with a pregnancy after breast cancer had a statistically significant better OS than those without a pregnancy (HR 0.46, 95% CI 0.27-0.77, P < 0.05). This systematic review and meta-analysis of retrospective cohort studies provides updated evidence that having a pregnancy in patients with prior history of hormone receptor-positive invasive early breast cancer appears safe without detrimental effect on prognosis.

The impact of an online educational game on breast cancer awareness among university female students, Malaysia: a pilot study

BackgroundBreast cancer is one of the world’s most prevalent cancer and the most common type of cancer in Malaysia. Interestingly, breast cancer in young women is more aggressive compared to older women and the survival rate among these groups of individuals is poor. Thus, breast cancer awareness is essential among young women as early detection is possible and treatment will be effective during which the disease is curable. Hence, the purpose of this study is to design and evaluate the impact of an educational game on breast cancer awareness among female university students in Malaysia.MethodsThis is a one-group pre-and post-intervention pilot study. It was conducted in Private and public higher education institutions around Malaysia. An online education game was created and used as the intervention. A self-administered questionnaire was administered to the participants during the pre-and post-intervention test to evaluate the online educational game on breast cancer awareness.ResultsA total of 52 responses were collected. The mean age of the participants was 21.98 (SD = 1.896) years. The findings showed a statistically significant median increase (p < 0.05) in breast cancer knowledge scores among participants in the post-intervention. A median increase in breast cancer knowledge score of 6 was shown when participants were exposed to the online education game (24.00) compared to before they were exposed to it (17.00).ConclusionUsing online educational games effectively raised awareness of breast cancer among university students. Online games can be used as a health educational tool to promote awareness of a topic of interest, as digital games can be accessed easily, game content can be tailored made or updated, and improve participant engagement in learning.

Triple-Negative Breast Cancer: Histopathologic Features, Genomics, and Treatment.

Triple-negative breast cancer (TNBC) is a heterogeneous and aggressive group of tumors that are defined by the absence of estrogen and progesterone receptors and lack of ERBB2 (formerly HER2 or HER2/neu) overexpression. TNBC accounts for 8%-13% of breast cancers. In addition, it accounts for a higher proportion of breast cancers in younger women compared with those in older women, and it disproportionately affects non-Hispanic Black women. TNBC has high metastatic potential, and the risk of recurrence is highest during the 5 years after it is diagnosed. TNBC exhibits benign morphologic imaging features more frequently than do other breast cancer subtypes. Mammography can be suboptimal for early detection of TNBC owing to factors that include the fast growth of this cancer, increased mammographic density in young women, and lack of the typical features of malignancy at imaging. US is superior to mammography for TNBC detection, but benign-appearing features can lead to misdiagnosis. Breast MRI is the most sensitive modality for TNBC detection. Most cases of TNBC are treated with neoadjuvant chemotherapy, followed by surgery and radiation. MRI is the modality of choice for evaluating the response to neoadjuvant chemotherapy. Survival rates for individuals with TNBC are lower than those for persons with hormone receptor-positive and human epidermal growth factor receptor 2-positive cancers. The 5-year survival rates for patients with localized, regional, and distant disease at diagnosis are 91.3%, 65.8%, and 12.0%, respectively. The early success of immunotherapy has raised hope regarding the development of personalized strategies to treat TNBC. Imaging and tumor biomarkers are likely to play a crucial role in the prediction of TNBC treatment response and TNBC patient survival in the future. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Oncologic efficacy of gonadotropin-releasing hormone agonist in hormone receptor-positive very young breast cancer patients treated with neoadjuvant chemotherapy.

Breast cancer in young women has been shown to have an aggressive behavior and poor prognosis. To evaluate the outcomes of young hormone receptor (HR)-positive patients with breast cancer treated with neoadjuvant chemotherapy (NAC), and the oncologic efficacy of gonadotropin-releasing hormone (GnRH) agonists. This retrospective study involved a prospectively enrolled cohort. We included patients diagnosed with invasive breast cancer who were treated with NAC followed by curative surgery at the Samsung Medical Center and Samsung Changwon Hospital between January 2006 and December 2017. Among patients with HR-positive and human epidermal grow factor 2 (HER2)-negative breast cancer, we analyzed the characteristics and oncology outcomes between the patients equal to or younger than 35 years and the patients older than 35 years. Among 431 patients with NAC and HR-positive/HER2-negative breast cancer, 78 were 35 years old or younger, and 353 patients were older than 35 years. The median follow-up was 71.0 months. There was no statistically significant difference in disease free survival (DFS, P = 0.565) and overall survival (P = 0.820) between the patients equal to or younger than 35 years and the patients older than 35 years. The two groups differed in that the GnRH agonist was used more frequently in the group of patients equal to or younger than 35 years than in the other group (52.4% vs 11.2%, P < 0.001). Interestingly, for the DFS according to the GnRH agonist in the group of patients equal to or younger than 35 years, patients treated with the GnRH agonist had better DFS (P = 0.037). Administration of GnRH agonists might improve the DFS rate of HR-positive/HER2-negative breast cancer in the equal to or younger than 35 years group of patients with NAC.

Landscape of young breast cancer under 35 years in China over the past decades: a multicentre retrospective cohort study (YBCC-Catts study)

The proportion of young breast cancer patients in China is significantly higher than in Western countries, and the clinicopathological characteristics and clinical problems faced by patients in China are different from those in Western countries too, so there is an urgent need to conduct some studies for young breast cancer patients in Asia. This study consisted of two breast cancer cohorts in China. The population-based cohort involved breast cancer cases diagnosed in 2000-2017 via cancer registration system, and we describe the epidemiological characteristics of the young breast cancer in China. The hospital-based cohort, patients eligible for enrollment were breast cancer in young women (≤35 years old) from eight centres in different regions of China, diagnosed and treated for the first time in six time periods (i.e., 2000, 2003, 2006, 2009, 2012, and 2015). Patient demographic characteristics and clinical features were compared among the six time periods using a trend test. The Kaplan-Meier method was used to generate survival curves, and the log-rank test was performed to compare OS and DFS. Univariate and multivariate analyses were carried out using Cox proportional hazards regression to estimate hazard ratios (HR) and 95% confidence intervals (CIs). In the population-based cohort, age-specific incidence and age-standardised percentages of breast cancer cases younger than 35 years were increased. The proportion of breast cancer under the age of 35 is increasing more rapidly in rural areas than in urban areas. In the hospital-based cohort, a total of 1308 young breast cancer patients (≤35 years old) were collected. Proportion of patients treated with adjuvant taxane or anthracycline combined with taxane is gradually increasing over the six time periods, and the proportion of patients undergoing breast-conserving surgery is gradually increasing too. Meanwhile, the patients treated with combined ovarian function suppression (OFS) endocrine therapy gradually increased, and the duration of endocrine therapy gradually longer. There is an increasing trend in 5-year disease-free survival (DFS) rate for the total population in the six time periods between 2000 and 2015, but no significant difference in overall survival (OS) rate was observed. Early staging and longer duration of endocrine therapy were factors associated with a favorable prognosis. The incidence of younger breast cancers under 35 years of age has gradually increased and the pattern of patient care has changed significantly over time, which may contribute to the improved prognosis of younger breast cancer patients.

Suboptimal use of ovarian function suppression in very young women with early breast cancer: a real-world data study.

The incidence of breast cancer in young women (BCYW) has increased in recent decades. Malignant disease in this subset is characterized by its aggressiveness and poor prognosis. Ovarian function suppression (OFS) in these patients improves survival especially in hormone receptor-positive (HR +) cases. The Regan Composite Risk (RCR) is a prognostic tool to identify high-risk HR + BC candidates for OFS. Our study sought to characterize a Chilean cohort of early HR + BCYW assessing the use of OFS and its related prognosis and the utility of RCR in our patients. This was a retrospective population cohort study that included ≤ 35-year-old early HR + /human epidermal growth factor receptor 2 -negative (HER2-) BC patients treated between 2001 and 2021. Analysis included clinical-pathological characteristics, treatment strategies, and survival. Also, we evaluated the association between RCR and survival. A total of 143 patients were included into our study, representing 2.9% of all early BC cases in our registry. Median age was 31years old (range: 19-35). Most patients (93%) received endocrine therapy (ET). Of these, 18% received OFS. No survival differences were observed among treatment strategies. Median RCR score for patients treated with CT plus ET was significantly higher vs. ET alone (2.95 vs. 1.91; p = 0.0001). Conversely, patients treated with tamoxifen alone had significantly lower RCR scores vs. OFS (2.72 vs. 3.14; p = 0.04). Higher RCR scores were associated with poorer overall survival. Less than 20% of very young women with early HR + /HER2-BC in our cohort received OFS, in most cases, this involved surgical oophorectomy. RCR score was higher in patients that underwent CT and OFS and was associated with survival, regardless of treatment. We confirm the RCR score as a valuable prognostic tool to identify high-risk BC patients who could benefit from OFS.

Relationship of The Characteristic Imaging Findings of Breast Cancer with Molecular Subtypes in Young Women.

The characteristic imaging findings of breast cancer in young women are not yet fully understood. It causes a delay in diagnosis by mixing with benign findings. To evaluate the relationship between the imaging and histopathological features of breast cancer in women aged under 40 years. In our center, 537 suspicious lesions were detected in a total of 15,223 adult female patients under 40 years who were evaluated by breast ultrasonography (US). As a result of the mammographic, histopathological, and immunohistochemical analysis, 101 lesions meeting the study criteria were included in the sample. The luminal subtypes of breast cancer mostly visualized as irregularly shaped spiculated lesions with calcification and architectural distortion mammography and presented as masses that were sometimes accompanied by increased echogenicity in the surrounding tissue on US. The human epidermal growth factor receptor 2 (HER2) enriched subtypes mostly had microlobulated or indistinct margins with heterogeneous echoes accompanied by high calcification on mammography. The triple-negative (TN) subtypes generally appeared as microlobulated lesions with angular or indistinct margins, hypo echogenicity, posterior enhancement or shadowing, and vascularization. Some radiological features of breast cancer in young women were found to be associated with molecular subtypes similar to other age groups in the literature. However, unlike other age groups, the incidences of the HER2-enriched subtype presenting with only calcification, TN subtypes presenting with circumscribed masses, and calcification were found to be low among the young women in our study.

Early Detection of Breast Cancer in Adolescent Women at The Tapak Sunan Balekambang Condet Islamic Boarding School, Jakarta

Background: The existence of Higher Education has three main tasks, namely carrying out education and teaching, research, and community service. These three things constitute the Tridharma of Higher Education. In Indonesia, breast cancer is the second most common cancer suffered by women after oral/cervical cancer. Breast cancer generally attacks women who are over 40 years old. However, young women can get this cancer. To find early symptoms of breast cancer can be detected early by women themselves. Women can routinely perform the Breast Self-Examination (BSE) method by massaging and feeling around their breasts to find out whether or not there are lumps around the breasts. BSE is an effective way to detect breast cancer as early as possible.&#x0D; Objective: Carry out community service by conducting activities to teach breast self-examination (BSE) to young women.&#x0D; Method: This community service activity consists of counseling related to information on early detection of breast cancer and followed by a demonstration of breast self-examination (BSE) using the Breast Phantom tool.&#x0D; Result: Counseling and early detection of breast cancer was attended by 45 students of Madrasah Aliyah. Most students do not know about early detection of breast cancer and how to check BSE. After being given information about BSE, adolescents felt satisfied and committed to be able to carry out early detection of breast cancer.&#x0D; Conclusion: Community service activities have been carried out regarding information on early detection of breast cancer in young women.
