Breast cancer under age 40: a different approach

Imaging Patterns in Breast Cancer for Women Under 40 Years: A Descriptive Cohort Study

BACKGROUND AND AIM

Breast cancer is the most frequently occurring malignant disease in women and remains the leading cause of cancer-related deaths among females worldwide. The aim of this study is to evaluate the imaging findings of breast cancer in women under the age of 40 and analyze their pathological patterns.

METHOD

A retrospective study was conducted from 2013 to 2019, involving 120 patients below 40 years of age with pathologically confirmed primary epithelial breast cancers. The data were collected from the electronic records of a tertiary hospital in Riyadh, Saudi Arabia. Mammograms were performed for 115 patients, ultrasounds were conducted for all patients, and MRI scans were carried out for 47 patients.

RESULTS

All radiological findings and clinical characteristics of the 120 cases were retrieved from our digital-based system. The majority of breast cancer patients (83.4%) were between 30 and 40 years old, and the most common clinical presentation was a mass (45.8%). Out of the 73 patients who underwent genetic tests, 32.9% tested positive for gene mutations. No statistically significant correlation was found between specific age groups and breast composition (P = 0.216), specific mammogram abnormalities such as masses (P = 0.262), or microcalcifications (P = 0.421). Ultrasonography was performed for all patients, with abnormalities detected in only one patient who was diagnosed with Paget's disease of the nipple. Masses, with or without parenchymal changes, were the predominant feature in 88.3% of cases.

CONCLUSION

The imaging findings in breast cancer cases typically involve masses with suspicious features, irregular shape, and spiculated margins on mammograms, and irregular shape with microlobulated or angular margins on ultrasound. MRI features commonly include masses with irregular shape and heterogeneous enhancement. The luminal B subtype was identified as the most prevalent pathological feature, characterized by a high proliferative index (Ki-67%).

Dose-Dense Chemotherapy Regimen for Breast Cancer Associated with Significant Decline in Ovarian Reserve

Purpose: To determine the impact of dose-dense chemotherapy administration on ovarian reserve in women undergoing treatment for breast cancer. Patients and Methods: We conducted a retrospective cohort study of reproductive age women who underwent dose-dense chemotherapy regimens with doxorubicin hydrochloride and cyclophosphamide with or without paclitaxel for a new diagnosis of breast cancer. We compared pre- and post-treatment serum antimullerian hormone (AMH) levels and assessed changes in AMH over time. Results: Fifty-seven patients met inclusion criteria. Median pre-treatment AMH was 2.9 ng/mL, whereas post-treatment AMH was 0.1 ng/mL, demonstrating a dramatic reduction in AMH levels after treatment with a dose-dense regimen. This change was independent of age and was sustained over 12 months from treatment completion. Conclusions: Dose-dense chemotherapy regimens for breast cancer lead to marked and sustained decreases in AMH irrespective of patient age.

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

BACKGROUND

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.

OBJECTIVE

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.

METHODS

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.

RESULTS

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%).

CONCLUSIONS

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.

Prognostic factor analysis and clinical significance of HER‑2‑positive breast cancers with negative lymph nodes and a tumor diameter ≤1 cm

The 2021 National Comprehensive Cancer Network guidelines recommend that adjuvant chemotherapy combined with trastuzumab be considered for human epidermal growth factor receptor 2 (HER-2)-positive breast cancer patients with small tumors (tumor diameter ≤1 cm) and negative lymph nodes. Additionally, the prognostic factors and clinical significance of HER-2-positive breast cancer with negative lymph nodes and a tumor diameter ≤1 cm remain unclear. In the present study, the clinical data and prognostic factors of 87 patients with HER-2-positive breast cancer with negative lymph nodes and a tumor diameter ≤1 cm admitted to Guangdong Women and Children Hospital from January 2013 to December 2019 were retrospectively analyzed. The median follow-up time was 70 months, the disease-free survival (DFS) of all patients was 94.3% and the overall survival (OS) was 100%. Univariate analysis of prognosis demonstrated that patients aged ≤40 years had significantly lower DFS than those aged >40 (80.8 vs. 100.0%, P<0.001). DFS was significantly improved in patients who were hormone-receptor-positive and patients who received endocrine therapy compared with patients who were estrogen receptor negative and patients who did not receive endocrine therapy (100.0 vs. 89.6%, P=0.039; 100.0 vs. 90.0%, P=0.049). Prognostic univariate analysis demonstrated that patient age, hormone receptor status and use of endocrine therapy were significantly related to the DFS (P<0.05), while none of these were independent factors related to the DFS in the prognostic multivariate analysis (P=0.240, P=0.976 and P=0.925). The proportion of patients with a tumor diameter 0.5-1 cm receiving adjuvant anti-HER-2 treatment was significantly greater compared with patients with tumors with a diameter ≤0.5 cm (46.4 vs. 18.6%, P<0.05). There was no significance difference in the DFS of patients treated with adjuvant chemotherapy with or without anti-HER-2 therapy with tumor diameters ≤0.5 cm (P>0.05), but there was a significant difference in the DFS of patients with a tumor diameter 0.5-1 cm (P<0.05). These results suggested that adjuvant chemotherapy, with or without anti-HER-2 therapy, may affect the prognosis of HER-2-positive breast cancer patients with negative lymph nodes and a tumor diameter of 0.5-1 cm. Therefore, it could be recommended that such patients receive adjuvant chemotherapy and anti-HER-2 therapy in the future.

Characteristics and prognosis of young breast cancer patients treated in a public comprehensive cancer centre in Brazil: A retrospective cohort study

BACKGROUND

The incidence of breast cancer among women under 41 years old varies worldwide, with higher rates observed in developing countries. These young women often face later-stage diagnoses. In this study, we examine a cohort of young women who were treated for breast cancer in São Paulo, Brazil.

METHODS

We conducted a retrospective cohort study involving women under 41 years old. Our objective was to describe patient and treatment characteristics, with the main outcomes being overall and disease-free survival. Our analysis explored the associations between age of menarche, history of breastfeeding, use of hormonal contraceptives, and age at diagnosis.

RESULTS

Our study included 493 patients with a mean follow-up of 62.8 months. The mean age of the patients was 34.6 (SD=4.19). Of the patients, 68% presented with locally advanced disease, and 19.27% were metastatic at the time of diagnosis. We observed significant associations between age of menarche and age at diagnosis (p = 0.0096), as well as age at diagnosis and breastfeeding (p = 0.0232). Chemotherapy was administered to 92.91% of the patients as part of their treatment, while 27.2% were eligible for breast-conserving surgery. During the follow-up period, 153 patients died, with disease progression being the cause of death in 73.2% of cases. The median survival time for the entire cohort is still under review, while the metastatic patients at diagnosis had a median survival time of 28.64 months (95%CI 20.21-40.89).

CONCLUSION

Our findings highlight significant associations between late-stage diagnosis and overall and disease-free survival in this patient age group. Given that the majority of patients present with locally advanced breast cancer, it is crucial to implement strategies that promote early-stage diagnosis and improve survival rates.

Prevalence of Iron Deficiency and its Association With Breast Cancer in Premenopausal Compared to Postmenopausal Women in Al Ahsa, Saudi Arabia

Iron is an essential cofactor needed for normal functions of various enzymes and its depletion lead to increase DNA damage, genomic instability, deteriorate innate, adaptive immunity, and promote tumor development. It is also linked to tumorigenesis of breast cancer cells through enhancing mammary tumor growth and metastasis. There is insufficient data describing this association in Saudi Arabia. This study aims to determine the prevalence of iron deficiency and its association with breast cancer among premenopausal and postmenopausal women referred for breast cancer screening center in Al Ahsa, Eastern Province of Saudi Arabia. Age, hemoglobin level, iron level, history of anemia, or iron deficiency were collected from patients' medical records. The included participants were grouped based on their age into premenopausal (<50 years) or postmenopausal (⩾50 years). The definition of low Hb implemented (Hb below 12 g/dL) and low total serum Iron levels (below 8 μmol/L). Logistic regression test was used to compute the association between having a positive cancer screening test (radiological or histocytological) and participant's lab results. The results are presented as odds ratios and 95% confidence intervals. Thrree hundred fifty-seven women were included, 77% (n = 274) of them were premenopausal. This group cases had more history of iron deficiency (149 [60%] vs 25 (30%), P = .001) compared to those in the postmenopausal group. The risk of having a positive radiological cancer screening test was associated with age (OR = 1.04, 95% CI 1.02-1.06), but negatively was associated with iron level (OR = 0.9, 95% CI 0.86-0.97) among the entire cohort. This study is the first to propose an association between iron deficiency and breast cancer among Saudi young females. This could suggest iron level as a new risk factor that may be used by clinicians to assess breast cancer risk.

Women with breast cancer, listening to the unheard voices: A qualitative study

<b>Objective:</b> This is a descriptive qualitative study with the aim of examining experiences of women diagnosed with breast cancer.<br /> <b>Methods</b>: The semi-structured interviews were conducted in the oncology clinic in Al Basheer Hospital in Jordan and included 15 women.<br /> <b>Results</b>: Several themes were identified such as knowledge before and after diagnosis, side effects of treatment, social and economic problems, lockdown and financial challenges in corona pandemic, coping strategies, and disclosure issues. Appropriate knowledge concerning causes of breast cancer, and side effects of administered drugs were lacking. Additionally, women were not comfortable telling others about their breast cancer diagnosis and considered it a private issue. During the COVID-19 pandemic, they faced many difficulties reaching hospitals, financial struggles, and inability to meet with their loved ones during lockdown.<br /> <b>Conclusion:</b> This study revealed the diversity of personalities and unique disposition of women regarding all the topics covered in the interviews. These differences should be considered in the support provided to these patients.

Black Women's Perspectives on Breast Cancer Risk Assessment

PURPOSE

The aim of this study was to gather the perspectives of Black women on breast cancer risk assessment through a series of one-on-one interviews.

METHODS

The authors conducted a cross-sectional qualitative study consisting of one-on-one semistructured telephone interviews with Black women in Tennessee between September 2020 and November 2020. Guided by the Health Belief Model, qualitative analysis of interview data was performed in an iterative inductive and deductive approach and resulted in the development of a conceptual framework to depict influences on a woman's decision to engage with breast cancer risk assessment.

RESULTS

A total of 37 interviews were completed, and a framework of influences on a woman's decision to engage in breast cancer risk assessment was developed. Study participants identified several emerging themes regarding women's perspectives on breast cancer risk assessment and potential influences on women's decisions to engage with risk assessment. Much of women's decision context was based on risk appraisal (perceived severity of cancer and susceptibility of cancer), emotions (fear and trust), and perceived risks and benefits of having risk assessment. The decision was further influenced by modifiers such as communication, the risk assessment protocol, access to health care, knowledge, and health status. Perceived challenges to follow-up if identified as high risk also influenced women's decisions to pursue risk assessment.

CONCLUSIONS

Black women in this study identified several barriers to engagement with breast cancer risk assessment. Efforts to overcome these barriers and increase the use of breast cancer risk assessment can potentially serve as a catalyst to address existing breast cancer disparities. Continued work is needed to develop patient-centric strategies to overcome identified barriers.

Quality Indicators Compliance and Survival Outcomes in Breast Cancer according to Age in a Certified Center

Age as a breast cancer (BC) prognostic factor remains debatable. Several studies have investigated clinicopathological features at different ages, but few make an age group direct comparison. The European Society of Breast Cancer Specialists quality indicators (EUSOMA-QIs) allow a standardized quality assurance of BC diagnosis, treatment, and follow-up. Our objective was to compare clinicopathological features, compliance to EUSOMA-QIs and BC outcomes in three age groups (≤45 years, 46-69 years, and ≥70 years). Data from 1580 patients with staged 0-IV BC from 2015 to 2019 were analyzed. The minimum standard and desirable target on 19 mandatory and 7 recommended QIs were studied. The 5-year relapse rate, overall survival (OS), and BC-specific survival (BCSS) were also evaluated. No meaningful differences in TNM staging and molecular subtyping classification between age groups were found. On the contrary, disparities in QIs compliance were observed: 73.1% in ≤45 years and 46-69 years women vs. 54% in older patients. No differences in loco-regional or distant progression were observed between age groups. Nevertheless, lower OS was found in older patients due to concurrent non-oncological causes. After survival curves adjustment, we underscored evidence of undertreatment impacting BCSS in ≥70 years women. Despite a unique exception-more invasive G3 tumors in younger patients-no age-specific differences in BC biology impacting outcome were found. Although increased noncompliance in older women, no outcome correlation was observed with QIs noncompliance in any age group. Clinicopathological features and differences in multimodal treatment (not the chronological age) are predictors of lower BCSS.

The impact of age on outcomes of breast cancer in different hormone receptor and HER2 groups

OBJECTIVE

The aim of the current study was to explore the association between age and outcomes in breast cancer.

METHODS

Patients during 2010-2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Overall survival (OS) and breast cancer-specific death (BCSD) were taken as endpoints. The restrict cubic spline graph (RCS) was used to explore the relationship between age and outcomes in patients, and the cumulative incidence of BCSD and non-BCSD was calculated using the Gray method. Age-specific gene expression profiles were studied using RNA sequence data from the Cancer Genome Atlas (TCGA) database to explore whether there were young age-related gene or gene sets.

RESULTS

A total of 142,755 patients with breast cancer were included. The hazard ratio (HR) of OS for Patients with stage I-III breast cancer was roughly stable before 53 years old and increased significantly after that, and the HR of BCSD for these patients showed a U-shaped distribution when plotted against age, with patients younger than 50 years and patients older than 70 years experiencing the worst survival. Further stratified analysis according to molecular subtype revealed that the U-shaped distribution of the HR of BCSD with was only found in the Hormone receptor-positive/HER2-negative (HoR+/HER2-) subgroup. The cumulative incidence plots showed that young age was associated with worse BCSD in the breast cancer patients with stage I-III and HoR+/HER2- subgroup. In stage IV breast cancer, there was a linearity of the relationship between poor OS and increasing age. We failed to find any differentially expressed age-specific genes between 20-40 years and 41-60 years groups in 258 patients with stage I-III and HoR+/HER2- subtype.

CONCLUSION

Young age could predict worse BCSD of patient with stage I-III and HoR+/HER2- breast cancer. The escalating therapy was recommended to young age breast cancer with stage I-III and HoR+/HER2- subtype.

Relapse-free survival in Sudanese women with non-metastatic breast cancer

Background

Breast cancer (BC) is the most frequently diagnosed cancer and a major cause of cancer mortality in Sudan. However, there is lack of data related to BC relapse. Therefore, this study was undertaken to estimate the 5-year relapse free survival (RFS) rate and factors related to BC relapse in Sudanese women with non-metastatic BC.

Methods

Data of BC women with BC diagnosed and treated at the National Cancer Institute-University of Gezira during 2012 were retrieved from medical records. The cases were followed-up through hospital records and telephone contact. Survival functions were calculated using Kaplan-Meier method and compared by log-rank test. The prognostic factors were tested using univariate and multivariable Cox regression analyses.

Results

We included 168 women with median age of 45 years (range, 22-83 years). 53.5%of women had stage III at time of diagnosis, whereas 4.2% and 42.3% of women presented with stage I and stage II, respectively. At the end of 5 years follow-up, with median follow-up period of 64 months, 94 (56.0%) women were alive in remission, 11 (6.5%) were alive with BC relapse, 49 (29.2%) were dead, and survival status was unknown in 14 (8.3%) women. Most of the occurred relapses were distant relapses. The 5-year RFS was 59%. The independent predictors of relapse were: larger primary tumor size (HR:1.84, 95% CI: 1.54-5.48, p=0.018); involved axillary lymph nodes with tumour (HR:  2.91, 95% CI:  1.53-7.91, p=0.001); not receiving adjuvant radiotherapy (HR: 2.2, 95% CI: 1.22-3.95, p=0.009); and not receiving hormone therapy (HR: 1.67, 95% CI: 1.01-2.76, p= 0.046).

Conclusion

We found a high risk of BC relapse in our resource-constrained settings. Advanced stages, not receiving adjuvant radiotherapy, and not receiving adjuvant hormone therapy were independent predictors associated with worse 5-year RFS. Therefore, enhancing the early diagnosis of BC and improving timely access to appropriate treatments represent key approaches to achieving better treatment outcomes.

Association of socioeconomic status with the clinical management and outcomes in young patients (≤35 years) diagnosed with breast cancer: A retrospective analysis

Background

Methods

Results

Discussion

•

Breast cancer occurring at 35 years or younger is rare and aggressive; medical management, therefore, should be equally aggressive, and early diagnosis is critical.

•

Retrospectively analyzed databases for breast cancer from both a government-run county hospital (CH) and a neighboring private hospital (PH) for 82 months.

•

Results of our study suggest a significant healthcare difference in very young breast cancer patients between the county and private hospital systems, which may have resulted in delays to seeking care. This difference may be a reflection of barriers in health literacy or access to medical care.

The different prognostic impact of age according to individual molecular subtypes in breast cancer

Purpose

Young age at diagnosis has been considered a poor prognostic factor. However, considering young age itself as an independent poor prognostic factor for all breast cancers is unwarranted. We analyzed the different prognostic effects of age as a prognostic factor according to molecular subtype.

Methods

We retrieved data from 1,819 patients with primary breast cancer at the breast cancer center between 2007 and 2012. We classified each molecular subtype in 3 age cohorts (<40, 40–50, and >50 years). The associations of age and molecular subtypes with relapse-free survival (RFS) and disease-specific survival (DSS) were assessed.

Results

Patients aged <40 years showed a poor histologic grade, hormone receptor negative expression than older patients, and had a higher proportion of triple-negative breast cancer (TNBC) (P < 0.001). This was thought to have led to a significantly shorter RFS than that of older patients (P < 0.001). In the subgroup analysis according to molecular subtypes, the poorer RFS was observed only in patients aged <40 years with luminal type breast cancer (P < 0.001). Age was an independent prognostic factor of RFS in luminal-type breast cancer (P = 0.001). However, no difference in RFS between age groups was found for patients with other subtypes (human epidermal growth factor receptor 2 overexpression, TNBC). No significant effect between age groups was found in DSS for patients with all molecular subtypes.

Conclusion

Age at diagnosis of breast cancer affected prognosis differently according to molecular subtype. Age itself is not an independent prognostic factor. Age of <40 years showed a limited worse prognostic impact of recurrence in luminal type breast cancer only.

Cellular and molecular mechanisms of breast cancer susceptibility

There is a plethora of recognized risk factors for breast cancer (BC) with poorly understood or speculative biological mechanisms. The lack of prevention options highlights the importance of understanding the mechanistic basis of cancer susceptibility and finding new targets for breast cancer prevention. Until now, we have understood risk and cancer susceptibility primarily through the application of epidemiology and assessing outcomes in large human cohorts. Relative risks are assigned to various human behaviors and conditions, but in general the associations are weak and there is little understanding of mechanism. Aging is by far the greatest risk factor for BC, and there are specific forms of inherited genetic risk that are well-understood to cause BC. We propose that bringing focus to the biology underlying these forms of risk will illuminate biological mechanisms of BC susceptibility.

S, Ananthi B, Selvaluxmy G. Real-World Experience of Treating Young Adult Patients with Breast Cancer from a Single Center in Southern India

Background Breast cancer in young adults is rare and accounts for 5 to 6% of all cancers in this age group. We conducted the present study to look at the demographic features, clinical presentation, and outcomes in this group of patients treated at our center.

Patients and Methods The study included breast cancer patients between the age of 15 and 30 years treated at our institute from January 2009 to December 2016. Data were analyzed retrospectively from case records. Event-free survival (EFS) and overall survival (OS) were calculated using the Kaplan–Meier method.

Results Young adult breast cancers were reported in 145 out of 6,000 patients (2.41%) diagnosed with breast cancer in the study period. The median age of the patients was 29 years (range: 21–30 years). Stage I, II, III, and IV was observed in 3.4, 33.7, 46.2, and 16.5% of patients, respectively. The median follow-up was 45 months (range: 1.7–128.1 months). The 5-year EFS and OS for stage I, II, III, and IV was 100, 74.5, 47.9, and 0% and 100, 90.8, 55.1, and 0%, respectively. On univariate analysis, stage of the disease and pregnancy-associated breast cancers were found to have a significant association with decreased EFS and OS (p < 0.001, p = 0.008 and p < 0.001, p = 0.001, respectively). On multivariate analysis, stage of disease and pregnancy-associated breast cancers remained significant predictors of EFS and OS.

Conclusion Breast cancers in young adults are rare but need to be diagnosed at an early stage to improve survival. Pregnancy-associated breast cancers need to be managed optimally without delay owing to their aggressive tumor biology.

Histo-Molecular Profile of Breast Cancer in Young Women in Togo

Introduction:

The frequency of breast cancer in young women, corresponding to women under 40 years of age; varies from 5% to 7% in developed countries. The objective of this study was to contribute to the improvement of the management of breast cancer in young women in Togo, by establishing the molecular classification of these cancers.

Methodology:

This was a retrospective descriptive and analytical study from January 2010 to December 2020.

Results:

About 35 cases of breast cancer were identified in women under 40 years of age. The average age was 35.4 ± 3.5 years. The right breast was affected in 18 cases (51.43%). Histologically, 30 cases (85.72%) were invasive carcinoma of no special type (NST), 2 cases (5.71%) were invasive lobular carcinoma and micro-papillary carcinoma respectively, and 1 case (2.86%) was tubular carcinoma. There were 6 cases (17.1%) of grade I, 25 cases (71.4%) of grade II, and 4 cases (11.4%) of grade III. Molecularly, there were 20 cases (57.1%) of triple-negative subtype, 6 cases (17.1%) of Luminal B subtype, 05 cases (14.3%) of HER2-enriched subtype and 4 cases (11.4%) of Luminal A subtype.

Conclusion:

Breast cancers of young Togolese women express very weakly hormone receptors, with a predominance of a triple negative subtype.

Distress Thermometer in breast cancer: systematic review and meta-analysis

Objective

This meta-analysis aimed to reach a summarised estimate of distress prevalence screened by Distress Thermometer (DT) among patients with breast cancer and compare different pooled prevalence estimated between different subgroups.

Methods

Two independent interviewers conducted a systematic search from PubMed, EMBASE, Ovid and Cochrane Library and checked related reviews and meta-analyses for eligible studies. The studies that identified distress of patients with breast cancer with DT were included. After extracting demographic characteristics and distress prevalence, the pooled analysis and the forest plot were completed by using STATA V.12.0 software. We conducted a subgroup analysis based on demographic and methodological characteristics of the studies. The publication bias was estimated by funnel plot.

Results

Seventeen studies describing 3870 patients with breast cancer were included in this meta-analysis. The distress prevalence of patients with breast cancer varied from 25.3% to 71.7% among these studies. The pooled distress prevalence was 50% (95% CI 49% to 52%) for the overall sample. The pooled distress prevalence rates in DT ≥7, DT ≥5 and DT ≥4 subgroups were 37% (95% CI 35% to 40%), 45% (95% CI 40% to 49%) and 62% (95% CI 60% to 65%), respectively. The distress prevalence had statistically significant differences between subgroups, which were differentiated by the initial time of distress identified, papers’ publication time, patients’ average age and country. There was no publication bias among the included studies.

Conclusion

The distress prevalence was high among patients with breast cancer. Routine and timely screening of distress for patients with breast cancer is of great significance in oncology management.

Recurrence rates and long-term survival factors in young women with breast cancer

Objectives:

To evaluate the factors related to breast cancer (BC) recurrence as well as survival in women ≤40 years old.

Methods:

This is a retrospective medical record review of women aged ≤40 years diagnosed with BC stages I to III between January 2009 and June 2017 at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. Demographic data collected included patients’ initial presentation (including age and date of diagnosis), imaging studies, tumor characteristics, type of surgery, systemic therapy (if any) received, and site of first recurrence. Data was analyzed to assess recurrence rate, disease-free survival (DFS), and overall survival (OS), and determine associated factors. Descriptive statistics were used to calculate the mean, median, standard deviation, and quartiles. Chi-square test was performed to test the association between 2 variables. Kaplan-Meier analyses were performed to assess survival distribution.

Results:

A total of 117 patients were included for analysis. Median follow-up was 16 months (range 0 to 99). Five-year DFS 57% and OS was 89%. Adjuvant chemotherapy was associated with a better DFS (hazard ratio of 0.204; 95% confidence interval, 0.050 to 0.832; p=0.027). Higher tumor, node, metastasis stage was significantly associated with worse DFS (p=0.034). Fewer postoperative follow-up visits significantly predicted recurrence (p=0.003).

Conclusion:

We found a high risk of BC recurrence among patients at our institution. Higher cancer stage, nonuse adjuvant chemotherapy, and low follow-up rate were significant predictive factors for recurrence.

Understanding the function of the tumor microenvironment, and compounds from marine organisms for breast cancer therapy

The pathology and physiology of breast cancer (BC), including metastasis, and drug resistance, is driven by multiple signaling pathways in the tumor microenvironment (TME), which hamper antitumor immunity. Recently, long non-coding RNAs have been reported to mediate pathophysiological develop-ments such as metastasis as well as immune suppression within the TME. Given the complex biology of BC, novel personalized therapeutic strategies that address its diverse pathophysiologies are needed to improve clinical outcomes. In this review, we describe the advances in the biology of breast neoplasia, including cellular and molecular biology, heterogeneity, and TME. We review the role of novel molecules such as long non-coding RNAs in the pathophysiology of BC. Finally, we provide an up-to-date overview of anticancer compounds extracted from marine microorganisms, crustaceans, and fishes and their synergistic effects in combination with other anticancer drugs. Marine compounds are a new discipline of research in BC and offer a wide range of anti-cancer effects that could be harnessed to target the various pathways involved in BC development, thus assisting current therapeutic regimens.

Does Age Matter? Estimating Risks of Locoregional Recurrence After Breast-conservative Surgery

BACKGROUND/AIM

In 2016, in the United States, more than 50% of breast cancer (BC) cases were diagnosed in patients older than 60 years of age. Our study aimed to estimate the risk of locoregional recurrence (LR) in patients who underwent breast-conservative treatment (BCT), according to age.

PATIENTS AND METHODS

This retrospective monocentric study analyzed 613 cases of patients who underwent BCT between 2003 and 2014. Patients were divided into groups according to age: Under70 (under 70 years old) and Over70 (above 70 years old). Margins width, histology results, prognostic and predictive factors were compared. Subgroup analysis was performed for patients who experienced LR.

RESULTS

LR Incidence among Under70 and Over70 was 5.4% and 1.7%, respectively (p<0.01). Group Over70 is characterized by larger tumors and a lower Ki67 index (p<0.01).

CONCLUSION

Operation time reduction, better aesthetic results and reduced LR risk support BCT. The Over70 group exhibited better outcomes in terms of LR despite larger tumor dimensions.

PD-L1 Expression and Tumor-infiltrating Lymphocytes in Breast Cancer: Clinicopathological Analysis in Women Younger than 40 Years Old

BACKGROUND/AIM

To evaluate the association between programmed cell death ligand 1 (PD-L1) expression on both tumor cells (TC) and inflammatory cells (IC), tumor infiltrating lymphocytes (TILs), CD3⁺ and CD8⁺ lymphocytes and other clinicopathological parameters in primary infiltrative breast cancer (IBC) of young women, a population shown to have a worse prognosis.

MATERIALS AND METHODS

A retrospective study was performed collecting data from patients younger than 40 years old. Forty-five young women with IBC were included. Whole tissue sections were used to evaluate all parameters.

RESULTS

Twenty percent (20%) of cases showed PD-L1 expression by tumor cells (PDL1TC) and 44.4% showed PD-L1 expression by immune cells (PDL1IC). Furthermore, 28.88% revealed high stromal TILs. PDL1TC and PDL1IC expression were significantly associated with tumor diameter and expression of estrogen (ER) and progesterone (PR) receptors and Ki67. PDL1TC expression was also associated with grade. High TILs were associated with tumor diameter, ER and Ki67 expression. PDL1TC, PDL1IC expression and TILs were associated with the density of CD3⁺ and CD8⁺ lymphocytes.

CONCLUSION

Our results are similar to those of other age groups, as reported in the literature.

Medicinal Herbs Used in Traditional Management of Breast Cancer: Mechanisms of Action

Background: Breast cancer is one of the principal causes of death among women and there is a pressing need to develop novel and effective anti-cancer agents. Natural plant products have shown promising results as anti-cancer agents. Their effectiveness is reported as decreased toxicity in usage, along with safety and less recurrent resistances compared with hormonal targeting anti-cancer agents. Methods: A literature search was conducted for all English-language literature published prior to June 2020. The search was conducted using electronic databases, including PubMed, Embase, Web of Science, and Cochrane Library. The search strategy included keywords such as breast cancer, herbs, anti-cancer biologically active components, clinical research, chemotherapy drugs amongst others. Results: The literature provides documented evidence of the chemo-preventative and chemotherapeutic properties of Ginseng, garlic (Allium sativum), Black cohosh (Actaea racemose), Tumeric (Curcuma longa), Camellia sinenis (green tea), Echinacea, Arctium (burdock), Flaxseed (Linum usitatissimum) and Black Cumin (Nigella sativa). Conclusions: The nine herbs displayed anti-cancer properties and their outcomes and mechanisms of action include inhibition of cell proliferation, angiogenesis and apoptosis as well as modulation of key intracellular pathways. However, more clinical trials and cohort human studies should be conducted to provide key evidence of their medical benefits.

Effects of Germline Pathogenic Variants, Cancer Subtypes, Tumor-related Characteristics, and Pregnancy-associated Diagnosis on Outcomes

BACKGROUND

Although breast cancer (BC) is uncommon in women age ≤ 35 years, women in this age group may have more aggressive cancer subtypes and high-risk pathogenic variants (HRPVs). Higher recurrence and mortality rates in young patients may be related to differences in tumor biology, pathologic mutation status, or treatment. The purpose of this study was to evaluate germline mutation status and other factors that affect recurrence-free survival (RFS) and overall survival (OS) in young women with BC.

MATERIALS AND METHODS

This was a retrospective study of women diagnosed with BC at age ≤ 35 years at Allina Health System from 2000 through 2017 (n = 306). Information was collected on germline mutation status, tumor characteristics (grade, hormone receptor, and human epidermal growth factor receptor 2), molecular subtype, pregnancy-associated cancers, and treatment. Survival analyses using Kaplan-Meier curves were conducted for RFS and OS.

RESULTS

With mean follow-up of 6.5 years, OS was 87.0% for invasive cancers, RFS was 84.7%; 69% obtained genetic testing, and 26.9% had HRPVs. There were no differences in RFS or OS between patients with HRPV versus unknown/low/moderate risk variants. Recurrence analysis showed increased recurrence rates in luminal B-like cancers followed by triple negative and human epidermal growth factor receptor 2-positive cancers (P = .041). Pregnancy-associated BC diagnoses, angiolymphatic invasion, and tumor stage were associated with reduced OS. In spite of young age at diagnosis, nearly one-third of patients did not receive germline genetic testing.

CONCLUSIONS

Similar survival patterns were found between women with HRPV versus no known mutations. Luminal B-like subtype, pregnancy-associated BC, angiolymphatic invasion, and cancer stage were associated with reduced OS.

Age-related differences in breast cancer mortality according to race/ethnicity, insurance, and socioeconomic status

BACKGROUND

We assessed breast cancer mortality in older versus younger women according to race/ethnicity, neighborhood socioeconomic status (nSES), and health insurance status.

METHODS

The study included female breast cancer cases 18 years of age and older, diagnosed between 2005 and 2015 in the California Cancer Registry. Multivariable Cox proportional hazards modeling was used to generate hazard ratios (HR) of breast cancer specific deaths and 95% confidence intervals (CI) for older (60+ years) versus younger (< 60 years) patients separately by race/ethnicity, nSES, and health insurance status.

RESULTS

Risk of dying from breast cancer was higher in older than younger patients after multivariable adjustment, which varied in magnitude by race/ethnicity (P-interaction< 0.0001). Comparing older to younger patients, higher mortality differences were shown for non-Hispanic White (HR = 1.43; 95% CI, 1.36-1.51) and Hispanic women (HR = 1.37; 95% CI, 1.26-1.50) and lower differences for non-Hispanic Blacks (HR = 1.17; 95% CI, 1.04-1.31) and Asians/Pacific Islanders (HR = 1.15; 95% CI, 1.02-1.31). HRs comparing older to younger patients varied by insurance status (P-interaction< 0.0001), with largest mortality differences observed for privately insured women (HR = 1.51; 95% CI, 1.43-1.59) and lowest in Medicaid/military/other public insurance (HR = 1.18; 95% CI, 1.10-1.26). No age differences were shown for uninsured women. HRs comparing older to younger patients were similar across nSES strata.

CONCLUSION

Our results provide evidence for the continued disparity in Black-White breast cancer mortality, which is magnified in younger women. Moreover, insurance status continues to play a role in breast cancer mortality, with uninsured women having the highest risk for breast cancer death, regardless of age.

MiR-1285-5p/TMEM194A axis affects cell proliferation in breast cancer

The onset of breast cancer among young patients is a major issue in cancer etiology. Our previous study has shown that poor prognosis in young women with breast cancer is associated with lower expression of the microRNA miR‐1285‐5p. In this study, we showed that the expression of miR‐1285‐5p is lower in tumor tissues than in normal tissues. Accumulating evidence suggests that miR‐1285‐5p plays critical roles in various types of cancers. However, the functional role of miR‐1285‐5p in breast cancer remains to be elucidated. Here, we showed the tumor‐suppressive role of miR‐1285‐5p and detailed its mechanism of action in breast cancer. Overexpression of miR‐1285‐5p significantly inhibited cell proliferation in breast cancer cells regardless of the tumor subtype. Among the target genes of miR‐1285‐5p, we found that transmembrane protein 194A (TMEM194A) was directly regulated by miR‐1285‐5p. Notably, separation of centrosomes from the nuclear envelope was observed upon knockdown of TMEM194A or overexpression of miR‐1285‐5p. In conclusion, our findings show that miR‐1285‐5p is a tumor suppressor via TMEM194A inhibition in breast cancer.

Clinicopathological Characteristics And Treatment Outcomes Of Breast Cancer Among Adolescents And Young Adults In A Developing Country

Purpose

Compared to Western societies, breast cancer diagnosis in our region is usually made at a younger age and at a more advanced stage. Breast cancer in younger patients tends to be more aggressive, and may result in a higher likelihood of long-term treatment-related toxicity and unique psychosocial problems. This study highlights the clinicopathological features and treatment outcomes in this age-group in a developing country like ours.

Methods

Consecutive patients aged 40 years or younger with a pathologically confirmed diagnosis of breast cancer treated and followed up at our institution were included. Medical records and hospital databases were searched for patients' characteristics and treatment outcomes.

Results

A total of 417 patients were enrolled. Median age at diagnosis was 35 (21-40) years. On presentation, 63 (15.1%) patients had metastatic disease, 50 (79.4%) with visceral metastasis. Patients with nonmetastatic disease had poor pathological features, including node-positivity (66.9%), grade III (51.4%), lymphovascular invasion (48.6%) and positive HER2 (31.5%). Breast-conserving surgery was performed on 32.9%, and only 36.5% of women had breast-reconstruction surgery. At a median follow-up of 59 months, 5-year overall survival for the whole group was 72%: 84% for nonmetastatic and 13% for those with metastatic disease. On Cox regression, nodal metastasis (adjusted HR 3.46, 95% CI 1.48-8.10; p=0.004) and grade III disease (HR 1.97, 95% CI 1.14-3.39; p=0.015) were associated with poor outcome.

Conclusion

Adolescents and young Jordanian adults with breast cancer present with more advanced-stage disease and more aggressive pathological features that reflect poorly on treatment outcomes.

Adverse reproductive health outcomes in a cohort of young women with breast cancer exposed to systemic treatments

Background

Breast cancer is the most common cancer in young women. Fortunately current survival rates of BC are significant which makes future fertility very important for quality of life of BC survivors. Chemotherapy carries a significant risk of infertility in BC patients so it is important to support fertility preservation decisions in premenopausal women. Amenorrhea has long been used as a surrogate marker of infertility in cancer patients but more reliable ovarian reserve (OR) markers are available. This study aimed to prospectively measure levels of OR in a cohort of young women with breast cancer exposed to chemotherapy, to identify adverse reproductive health outcomes in this population and to assess the influence of patient and treatment-related factors in those outcomes.

Methods

This prospective observational study included premenopausal women with breast cancer aged 18–40 years at diagnosis and proposed for (neo) adjuvant chemotherapy. Patients were evaluated before, during and a minimum of 9 months after the end of chemotherapy. Reproductive health outcomes: menses, hormonal and ultrasound OR markers, recovery of ovarian function and Premature Ovarian Insufficiency (POI).

Results

A total of 38 patients were included (mean age 32.9 ± 3.5 years). Levels of OR significantly decreased during the study. At the last follow up, 35 patients had AMH below the expected values for age; eight presented postmenopausal FSH; ten had not recovered their ovarian function and five met the defined criteria for POI. Age and baseline AMH were positively correlated with AMH at the last follow-up. AMH levels were higher in the group of patients treated with trastuzumab and lower in those under hormonal therapy, at the last follow-up.

Conclusions

Significant effects of systemic treatments on several reproductive outcomes and a strong relation of those outcomes with patient’s age and baseline level of AMH were observed. Our results point to a possible lower gonadotoxicity when treatment includes targeted therapy with trastuzumab. Also, this investigation highlights the lack of reliable OR markers in women under hormonal therapy.

Oncologic Outcomes in Young Adults With Kidney Cancer Treated During the Targeted Therapy Era

BACKGROUND

The objective of this study was to determine the outcomes of young adults with kidney cancer treated during the targeted therapy era and evaluate the impact of young age on survival.

MATERIALS AND METHODS

We reviewed the records from 445 patients younger than 55 years with kidney cancer at a single institution from 2006 to 2017. Overall survival (OS) and recurrence-free survival were estimated with the Kaplan-Meier method and log-rank test. Cox proportional hazards regression was used to determine the impact of clinical and pathologic variables on all-cause mortality.

RESULTS

Overall, 104 (23%) patients 40 years or younger were compared with 341 (77%) patients who were 41 to 55 years old. Younger patients presented with more advanced stages of the disease, including metastasis at diagnosis, positive lymph nodes, venous tumor thrombus and had more non-clear cell tumors (54% vs. 30%; P < .001). Young adults had significantly worse OS at 2 and 5 years (67% vs. 82% and 53% vs. 69%, respectively). Younger patients with metastatic disease received targeted agents less often compared with the older group (64% vs. 75%). There was no difference in recurrence-free survival across patients with localized disease. Independent prognostic factors associated with increased mortality were metastasis at diagnosis, pT2 or greater, and age younger than 40 years (hazard ratio, 1.65; 95% confidence interval, 1.0-2.6; P = .03).

CONCLUSION

Patients younger than 40 years with kidney tumors treated during the targeted therapy era have worse OS compared with older adults. Young age is an independent predictor of mortality.

Young-onset breast cancer: a poor prognosis only exists in low-risk patients

The number of reported young breast cancer cases has increased dramatically recently. The impact of age on the outcomes of breast cancers remains controversial. Our study aimed to explore the factors that can stratify the impact of young age on the prognosis of early breast cancer patients. In total, 244,324 patients with early breast cancer in the Surveillance, Epidemiology, and End Results database were identified from 1990 to 2007. Survival curves were generated using the Kaplan-Meier method. The 5- and 10-year cancer-specific survival (CSS) rates were calculated using the Life-Table method. Multivariable analyses were used to identify prognosti c variables (without age) to construct the nomograms. The risk score developed from the nomogram was used to classify the cohort into three subgroups (low-, medium- and high-risk subgroup). Approximately 8.89% of women were diagnosed with breast cancer at a young age (≤ 40 years). Clinical nomogram had the potential ability to predict CSS accurately with a well C-index (0.785). Subgroup analysis indicated that the risk score as the sole factor can stratify the impact of young age on the prognosis of early breast cancer patients. Young breast cancer patients had a worse prognosis in the low-risk (HR=0.61; 95% CI: 0.57-0.65; P<0.001) or medium-risk subgroup (HR=0.89; 95% CI: 0.85-0.93; P<0.01) than in the high-risk subgroup (P=0.431). In conclusion, the worse prognosis of young women only appeared in the low- and medium-risk subgroups rather than in the high-risk subgroup. The risk score yielded from the nomogram model can assist clinical decision making for young breast cancer patients.

Shikimic acid promotes estrogen receptor(ER)-positive breast cancer cells proliferation via activation of NF-κB signaling

Shikimic acid (SA), a widely-known hydroaromatic compound enriched in Bracken fern and Illicium verum (also known as Chinese star anise), increases the risk of gastric and esophageal carcinoma, nevertheless, the influence of SA on breast cancer remains indistinct. Herein we found that, with models in vitro, SA significantly promoted estrogen receptor(ER) positive cells proliferation and NF-κB activation was involved in it. Moreover, our data showed that IκBα, a critically endogenous inhibitor of NF-κB, was repressed. Subsequently, we found increase of miR-300 by SA treatment sand miR-300 could target IκBα mRNA. Additionally, inhibition of miR-300 abrogated the repression of IκBα by SA. As a result, miR-300 was also involved in NF-κB activation and breast cancer cells proliferation promotion due to SA exposure. Taken together, with ER-positive breast cancer cell models in vitro, MCF-7 and T47D, our results implied that SA promoted breast cancer cells proliferation via a miR-300-induced NF-κB dependent pathway controlling cell cycle proteins.

Longitudinal effect of emotional processing on psychological symptoms in women under 50 with breast cancer

Breast cancer is a potential traumatic event associated with psychological symptoms, but few studies have analysed its impact in under-50 women. Emotional processing is a successful function in integrating traumatic experiences. This work analysed the relationship between emotional processing and psychological symptoms during three phases of treatment (before hospitalization, counselling after surgery and adjuvant therapy) in 50 women under the age of 50 with breast cancer. Mixed-effects models tested statistical differences among phases. There were significant differences in symptoms during the treatments: the levels of anxiety decrease from T1 to T3 (0.046), while those of hostility increase (<0.001). Emotional processing is a strong predictor of all symptoms. Clinical implications are discussed.

Young Patients with Hormone Receptor-Positive Breast Cancer Have a Higher Long-Term Risk of Breast Cancer Specific Death

Purpose

Although it is widely accepted that hormone receptor (HR) status is associated with later post-diagnostic periods, a debate exists as to whether the association is independent of age. The aim of our study was to confirm the impact of HR status on later period breast cancer-specific death (LP-BCSD) and later period non-breast cancer-specific death (LP-non-BCSD) in different age subgroups.

Methods

Surveillance, Epidemiology, and End Results databases were utilized to identify 181,108 breast cancer patients with > 5 years survival. The cumulative incidence of LP-BCSD and LP-non-BCSD was calculated using the Gray method. The subdistribution hazard ratio (SHR) of variables was estimated via the Fine and Gray proportional hazard regression model. Subgroup analyses for LP-BCSD and LP-non-BCSD were performed according to the HR status.

Results

The risk of LP-BCSD was exceeded by that of LP-non-BCSD at > 5 years since the diagnosis, particularly in old women. The competing risk regression model indicated that hormone receptor-positive (HR+) was an independent factor for more LP-BCSD (hazard ratio, 1.54; 95% confidence interval, 1.44–1.54; p < 0.001). However, stratified analysis indicated that HR+ was only associated with more LP-BCSD in the young women subgroup. Although HR+ was associated with more LP-non-BCSD, the predictive value of HR+ for LP-non-BCSD was eliminated after adjusting for age.

Conclusions

HR+ was related to LP-BCSD in the premenopausal population. LP-BCSD should be an optimal endpoint in future trials designed to evaluate the role of extended adjuvant endocrine therapy.

Invasive breast cancers in adolescent and young adult women show more aggressive immunohistochemical and clinical features than those in women aged 40-44 years

BACKGROUND

Limited knowledge exists concerning the clinicopathological features of breast cancers (BCs) occurring in adolescent and young adult (AYA) women. We evaluated tumor characteristics in AYA women in comparison with those in middle-aged premenopausal women.

METHODS

From consecutive AYA patients (< 35-year-old) with invasive BC in a single institute, 82 patients first treated with surgery were examined. As the control group, 82 tumors from middle-aged premenopausal patients (40-44 years) were selected by matching pathological T and N factors. We compared habitual factors, immunohistochemical parameters, and patient outcome between the two groups.

RESULTS

Most of the study population (148 of 164, 90.2%) were in the early clinical stages (stage I or II). In the AYA group, the number of childbirths was smaller (p < 0.0001), while the volume of alcohol consumption was larger (p < 0.0001), and palpable primary tumors were more frequent (p < 0.01) than in the control group. The positivities of estrogen receptor, progesterone receptor, and androgen receptor were lower (p < 0.001, p = 0.03, and p < 0.001, respectively), and the triple-negative (TN) BCs rates were higher (p < 0.01) in the AYA group. Distant recurrence-free survival (DRFS) curves were different in the whole population (p = 0.02) and in hormone receptor-positive cases (p = 0.01).

CONCLUSIONS

We confirmed that BCs occurring in AYA women had more aggressive features than those of the older premenopausal women in terms of a high proportion of TN subtypes and a lower DRFS.

Metastatic and triple-negative breast cancer: challenges and treatment options

The major current conventional types of metastatic breast cancer (MBC) treatments include surgery, radiation, hormonal therapy, chemotherapy, or immunotherapy. Introducing biological drugs, targeted treatment and gene therapy can potentially reduce the mortality and improve the quality of life in patients with MBC. However, combination of several types of treatment is usually recommended. Triple negative breast cancer (TNBC) accounts for 10-20% of all cases of breast carcinoma and is characterized by the low expression of progesterone receptor (PR), estrogen receptor (ER), and human epidermal growth factor receptor 2 (HER2). Consequently, convenient treatments used for MBC that target these receptors are not effective for TNBC which therefore requires special treatment approaches. This review discusses the occurrence of MBC, the prognosis and predictive biomarkers of MBC, and focuses on the novel advanced tactics for treatment of MBC and TNBC. Nanotechnology-based combinatorial approach for the suppression of EGFR by siRNA and gifitinib is described.

Where youth matters-clinicopathologic characteristics and emerging trends in treatment and outcomes in young Irish women with breast cancer

BACKGROUND

Young women with breast cancer (YWBC) represent 7-12% of breast cancer diagnoses and ostensibly have more biologically aggressive subtypes with higher relapse and mortality rates. We studied the clinical and pathological characteristics in YWBC and examined how outcomes and treatment have evolved.

METHODS

YWBC were identified from pathology databases at two tertiary centers. Patients were divided into two cohorts: those diagnosed from 2000 to 2005 (C1) and from 2006 to 2015 (C2). Data were retrieved from clinical, radiology, and histology databases. Statistical analysis was performed using R® (V3.2.0).

RESULTS

We identified 345 patients. Median age was 36 years (23-39 years). Mastectomy was performed in 232 patients (67.2%) and axillary lymph node clearance (ALNC) in 207 patients (60% [C1 82.7 vs. C2: 49.4%, p < 0.001]). One hundred-seventy patients (49%) were ER + HER2-, 88 (25.5%) were HER2+, and 58 (16.8%) were triple negative. Eighty patients (23.2%) received neoadjuvant therapy. Pathological complete response rates were statistically similar between C1 and C2 [C1 1 (0.9%) vs C2 16 (6.8%) p = 0.1]. Distant relapse occurred in 59 (19%) patients. There was a higher relapse rate (RR) in C1 [27 (32.1%) vs. 32 (15.7%), p < 0.002). HER2+ and ER+ HER2- patients in C1 had higher RRs than C2. Median overall survival in patients with metastatic disease was 29 months (range 2-119 months).

CONCLUSION

Locally advanced disease was more prevalent in YWBC. Mastectomy and ALNC rates were high and most received multimodal treatment. The extent of axillary surgery declined over time. Outcomes were unchanged in triple negative patients. These remain a priority for research.

Male breast cancer: a nation-wide population-based comparison with female breast cancer

OBJECTIVE

Describe prognostic parameters of Danish male breast cancer patients (MBCP) diagnosed from 1980-2009. Determine all-cause mortality compared to the general male population and analyze survival/mortality compared with Danish female breast cancer patients (FBCP) in the same period.

MATERIAL AND METHODS

The MBCP cohort was defined from three national registers. Data was extracted from medical journals. Data for FBCP is from the DBCG database. Overall survival (OS) was quantified by Kaplan-Meier estimates. Standardized mortality ratios (SMRs) were calculated based on mortality rate among patients relative to the mortality rate in the general population. The association between SMR and risk factors were analyzed in univariate and multivariable Poisson regression models. Separate models for each gender were used for the analyses.

RESULTS

We found a marked difference in OS for the two genders. For the total population of MBCP, 5- and 10-year survivals were 55.1% and 31.7%, respectively. For FBCP, the corresponding figures were 76.8% and 59.3%. Median age at diagnosis for FBCP was 61 years and 70 years for MBCP. By applying SMR, the difference in mortality between genders equalized and showed pronounced age-dependency. For males <40 years, SMR was 9.43 and for females 19.56 compared to SMR for males 80 + years (0.95) and females 80 + years (0.89). During the period 1980-2009, the risk of dying gradually decreased for FBCP (p < .0001). The risk 1980-1984 was 35% higher than 2005-2009 (RR 1.35). Although the risk of dying for MBCP was also lowest in 2005-2009, there was no clear tendency (p = .1439). The risk was highest in 1990-1994 (RR =2.48).

CONCLUSION

We found better OS for FBCP than for MBCP. But SMR showed similar mortality rate for the two genders, except for very young FBCP, who had higher SMR. Furthermore, significantly improved survival over time for FBCP was observed, with no clear tendency for MBCP.

Impact of Symptom and Social Support on Fertility Intention in Reproductive-Age Women With Breast Cancer

This study describes the fertility intention and explores factors related to fertility intention in reproductive-age women with breast cancer in Taiwan. In this cross-sectional study, women of childbearing age who had been diagnosed with breast cancer completed a face-to-face survey that included demographic, disease, and symptom-related data, and social support and fertility intention information. The mean fertility intention score among the 223 participants was "medium" (M ± SD = 41.18 ± 12.62). Higher symptom severity, especially for distress, was related to lower fertility intention. Instrumental support from families and friends was positively associated with fertility intention score. Younger women had better fertility intention scores than older women. The Sobel test showed that age mediated menopause and fertility intention. The findings offer the evidence of the needs to control symptoms and provide sufficient instrumental support regarding fertility after completing chemotherapy.

Preoperative [18]fluorodeoxyglucose-positron emission tomography/computed tomography in early stage breast cancer: Rates of distant metastases

AIM

To investigate rates of distant metastases (DM) detected with [18]fluorodeoxyglucose-positron emission tomography/computed tomography (18FDG-PET/CT) in early stage invasive breast cancer.

METHODS

We searched the English language literature databases of PubMed, EMBASE, ISI Web of Knowledge, Web of Science and Google Scholar, for publications on DM detected in patients who had 18FDG-PET/CT scans as part of the staging for early stages of breast cancer (stage I and II), prior to or immediately following surgery. Reports published between 2011 and 2017 were considered. The systematic review was conducted according to the PRISMA guidelines.

RESULTS

Among the 18 total studies included in the analysis, the risk of DM ranged from 0% to 8.3% and 0% to 12.9% for stage I and II invasive breast cancer, respectively. Among the patients with clinical stage II, the rate of occult metastases diagnosed by 18FDG-PET/CT was 7.2% (range, 0%-19.6%) for stage IIA and 15.8% (range, 0%-40.8%) for stage IIB. In young patients (< 40-year-old), 18FDG-PET/CT demonstrated a higher prevalence of DM at the time of diagnosis for those with aggressive histology (i.e., triple-negative receptors and poorly differentiated grade).

CONCLUSION

Young patients with poorly differentiated tumors and stage IIB triple-negative breast cancer may benefit from 18FDG-PET/CT at initial staging to detect occult DM prior to surgery.

Fertility Preservation in Cancer Patients: In Vivo and In Vitro Options

Oocyte, embryo and ovarian tissue cryopreservation are being increasingly proposed for fertility preservation among cancer patients undergoing therapy to enable them to have babies after the cancer is cured. Embryo cryopreservation is not appropriate for single girls without any sperm partner and also because oocyte retrieval is an extended procedure, it is impossible in cases requiring immediate cancer cure. Thus ovarian tissue cryopreservation has been suggested for fertility preservation especial in cancer patients. The main goal of ovarian cryopreservation is re-implanting the tissue into the body to restore fertility and the hormonal cycle. Different cryopreservation protocols have been examined and established for vitrification of biological samples. We have used Cryopin to plunge ovarian tissue into the liquid nitrogen and promising results have been observed. Ovarian tissue re-implantation after cancer cure has one problem- the possibility of recurrence of malignancy in the reimplanted tissue is high. Xenografting-implantation of the preserved tissue in another species- also has its drawbacks such as molecular signaling from the recipient. In vitro follicle culturing is a safer method to obtain mature oocytes for fertilization and the various studies that have been carried out in this area are reviewed in this paper.

Breast cancer treatment costs in younger, privately insured women

PURPOSE

Younger women (under age 45 years) diagnosed with breast cancer often face more aggressive tumors, higher treatment intensity, lower survival rates, and greater financial hardship. The purpose of this study was to estimate breast cancer costs by stage at diagnosis during the first 18 months of treatment for privately insured younger women.

METHODS

We analyzed North Carolina cancer registry data linked to claims data from private insurers from 2003 to 2010. Breast cancer patients were split into two cohorts: a younger and older group aged 21-44 and 45-64 years, respectively. We conducted a cohort study and matched women with and without breast cancer using age, ZIP, and Charlson Comorbidity Index. We calculated mean excess costs between breast cancer and non-breast cancer patients at 6, 12, and 18 months.

RESULTS

For younger women, AJCC 6th edition stage II cancer was the most common at diagnosis (40%), followed by stage I (34%). On the other hand, older women had more stage I (46%) cancer followed by stage II (34%). The excess costs for younger and older women at 12 months were $97,486 (95% confidence interval [CI] $93,631-101,341) and $75,737 (95% CI $73,962-77,512), respectively. Younger breast cancer patients had both a higher prevalence of later-stage disease and higher within-stage costs.

CONCLUSIONS

The study reports high costs of treatment for both younger and older women than a non-cancer comparison group; however, the estimated excess cost was significantly higher for younger women. The financial implications of breast cancer treatment costs for younger women need to be explored in future studies.

Demographic Disparities in Late-Stage Diagnosis of Breast and Colorectal Cancers Across the USA

BACKGROUND

We determined whether there were disparities in the likelihood of being diagnosed at a late stage for breast cancer (BC) or colorectal cancer (CRC) in each of 40 states, using the recently available US Cancer Statistics (USCS) database.

METHODS

We extracted 981,457 BC cases and 558,568 CRC cases diagnosed in 2004-2009. Separate multilevel regressions were run for each state and each cancer type. Models included person and area-level covariates and were identically specified across states. The disparities foci were race or ethnicity (white, African-American, Hispanic, Asian, all other), gender, and age (<40, 40-49, 50-64, 65-74, and 75+). Using whites, males, and the oldest age group as reference groups, we noted the statistically significant disparities coefficients (p value ≤0.05) and translated the findings via a set of maps of states in the USA.

RESULTS

National disparity estimates were not consistent with disparities identified in the states. Some states had estimates consistent with the national average, while others did not. Patterns of disparities across states were different for each covariate and mapped separately.

CONCLUSION

National disparity estimates may mask what is true at the more local, state level because national estimates can confound the effects of race with place. Cancer control efforts are local and require locally relevant information to assess needs. Findings from the period 2004-2009 establish valuable benchmarks against which to assess changes following national health reform implemented in 2010. The USCS database is a valuable new resource that will facilitate future disparities research.

Breast cancer in young women: an overview

Despite dramatic advances in cancer research setting, breast cancer remains a major health problem and represents currently a top biomedical research priority. Worldwide, breast cancer is the most common cancer affecting women, and its incidence and mortality rates are expected to increase significantly the next years. Recently the researchers' interest has been attracted by breast cancer arising in young women. Current evidence suggests that in women aged <45 years, breast cancer is unquestionably the leading cause of cancer-related deaths. This type of cancer seems to be highly heterogeneous and has potentially aggressive and complex biological features. However, management strategies, recommendations and options are not age based and the 'complex' biology of this type of cancer remains uncertain and unexplored. In this review, we summarize the latest scientific information on breast cancer arising in young women highlighting the heterogeneity and the complex nature of this type of cancer.

Anti-müllerian hormone levels and evolution in women of reproductive age with breast cancer treated with chemotherapy

BACKGROUND

Long-term consequences of cancer treatments in young women, and especially fertility issues, are gaining attention as survival rates increase. Breast cancer is the most frequent malignancy in women of reproductive age.

AIM

The purpose of this review is to describe serum anti-müllerian hormone (AMH) level at diagnosis and its evolution during and after chemotherapy in women of reproductive age treated for breast cancer. Second, the impact of taxanes on AMH, the association between AMH and amenorrhea, and the comparison of AMH with other hormonal markers of ovarian reserve were studied.

METHODS

A systematic PubMed search was conducted on all articles, published up to April 2016 and related to AMH in women suffering from breast cancer using the following key words: AMH, müllerian-inhibiting substance, ovarian reserve, ovarian function, breast cancer, gonadotoxicity, ovarian toxicity, amenorrhea, chemotherapy, and menopause.

RESULTS

AMH levels rapidly fall down to undetectable levels in most women during chemotherapy and generally persist at very low levels in most women after the treatment. Taxanes seem to impact negatively ovarian function, but data on ovarian reserve are scarce. AMH is a predictor of the occurrence of chemotherapy-related amenorrhea and is the most relevant hormonal marker of ovarian reserve.

CONCLUSION

Serum AMH is a relevant tool for ovarian reserve assessment and follow-up during treatment in premenopausal women with breast cancer. Further large prospective studies are necessary to determine its predictive interest for post-treatment residual fertility, and eventually use it in fertility preservation counseling before treatment initiation.

Breast Cancer Metastasis Associations with Clinicopathological Characteristics in Mexican Women Younger than 40 Years of Age

Background:

In Mexico, breast cancer (BCa) is in first place regarding cancer mortality and has been established as a priority health issue. The incidence of metastasis from BCa is very high and presents as the principal mortality factor among women younger than 40 years of age. OBJECTIVE. To determine any associations between clinicopathological characteristics and metastasis in Mexican women under 40 years of age.

Methods:

During the 2010–2015 period, a total of 180 female BCa cases seen at the Navy General High Specialty Hospital, SEMAR, in Mexico City; we collected information on 20 patients with BCa younger than 40 years of age. Statistical analyses were conducted using the Kolmogorov–Smirnov, Students t, Fisher, Chi square, and Mantel–Haenszel tests.

Results:

The prevalence of women with BCa younger than the age of 40 years during the 2010–2015 period was 13.3%. We found a high frequency of obesity in of these cases (>75%); 100% of obese patients with a history of smoking presented with metastasis (p <0.05). In addition, the hormone phenotype was important; HER2-positive cases were 12 times more likely tto exhibit metastasis (p <0.05), while expression of estrogen and progesterone receptors appeared to be protective. Diabetes mellitus in combination with smoking was also a risk factor for development of metastasis (p <0.05).

Conclusion:

In this study, we obtained essential data regarding risk of metastasis in young breast cancer cases which could be useful for predicting disease evolution and treatment response.

Baby Boomers and Birth Certificates: Early-Life Socioeconomic Status and Cancer Risk in Adulthood

BACKGROUND

Early-life socioeconomic status (SES) may play a role in cancer risk in adulthood. However, measuring SES retrospectively presents challenges. Parental occupation on the birth certificate is a novel method of ascertaining early-life SES that has not been applied in cancer epidemiology.

METHODS

For a Baby-Boom cohort born from 1945-1959 in two Utah counties, individual-level Nam-Powers SES (Np-SES) was derived from parental industry/occupation reported on birth certificates. Neighborhood SES was estimated from average household income of census tract at birth. Cancer incidence was determined by linkage to Utah Cancer Registry records through the Utah Population Database. Hazard ratios (HR) for cancer risk by SES quartile were estimated using Cox proportional hazards regression.

RESULTS

Females with low Np-SES at birth had lower risk of breast cancer compared with those in the highest Np-SES group [HR_Q1/Q4 = 0.83; 95% confidence interval (CI), 0.72-0.97; HR_Q2/Q4 = 0.81; 95% CI, 0.69-0.96]. Np-SES was inversely associated with melanoma (HR_Q1/Q4 = 0.81; 95% CI, 0.67-0.98) and prostate cancer (HR_Q1/Q4 = 0.70; 95% CI, 0.56-0.88). Women born into lower SES neighborhoods had significantly increased risk for invasive cervical cancer (HR_Q1/Q4 = 1.44; 95% CI, 1.12-1.85; HR_Q2/Q4 = 1.33; 95% CI, 1.04-1.72). Neighborhood SES had similar effects for melanoma and prostate cancers, but was not associated with female breast cancer. We found no association with SES for pancreas, lung, and colon and rectal cancers.

CONCLUSIONS

Individual SES derived from parental occupation at birth was associated with altered risk for several cancer sites.

IMPACT

This novel methodology can contribute to improved understanding of the role of early-life SES on cancer risk. Cancer Epidemiol Biomarkers Prev; 26(1); 75-84. ©2016 AACR.

Considerations for the Treatment of Young Patients with Breast Cancer

Breast cancer in the young patient, generally defined as younger than 40 years, is a rare but important problem. In the US, over 24,000 women under age 45 are diagnosed with breast cancer each year and nearly 2,500 young women die annually of the disease. This review is intended to address issues specific to caring for the young breast cancer patient including diagnosis, genetic counseling, tumor biology, surgery, and potential for development of contralateral breast cancer. Additionally, there are psychosocial considerations unique to this age group which should be addressed as part of a comprehensive, multi-disciplinary team approach including discussions about fertility, sexual function, behavioral health, and quality of life.
