Unique aspects of caring for young breast cancer patients

Androgen receptor function and targeted therapeutics across breast cancer subtypes

Despite significant progress in breast cancer (BC) therapy, it is globally the most commonly diagnosed cancer and leads to the death of over 650,000 women annually. Androgen receptor (AR) is emerging as a potential new therapeutic target in BC. While the role of AR is well established in prostate cancer (PCa), its function in BC remains incompletely understood. Emerging data show that AR's role in BC is dependent on several factors including, but not limited to, disease subtype, tumour microenvironment, and levels of circulating oestrogens and androgens. While targeting AR in PCa is becoming increasingly effective, these advances have yet to make any significant impact on the care of BC patients. However, this approach is increasingly being evaluated in BC and it is clear that improvements in our understanding of AR's role in BC will increase the likelihood of success for AR-targeted therapies. This review summarizes our current understanding of the function of AR across BC subtypes. We highlight limitations in our current knowledge and demonstrate the importance of categorizing BC subtypes effectively, in relation to determining AR activity. Further, we describe the current state of the art regarding AR-targeted approaches for BC as monotherapy or in combination with radiotherapy.

Attentional Bias Toward Reproduction-Related Stimuli and Fertility Concerns Among Breast Cancer Survivors

The current study examined whether an attentional bias exists for reproduction-related visual cues among breast cancer survivors and its relationship with fertility concerns and emotional distress. Breast cancer survivors (n = 38) aged 18-40 were compared to 37 healthy women recruited from the general population. Attentional bias was investigated using a visual dot-probe task and response times (RT) were measured. Participants also completed several questionnaires, including the Reproductive Concerns After Cancer Scale (RCACS) and the Hospital Anxiety and Depression Scale (HADS). Biased cognitive processing toward reproduction-related stimuli was observed for all young women. However, attentional bias was a significant predictor of concerns about partner disclosure of fertility status, with higher bias scores associated with higher levels of concern only for breast cancer survivors. The desire to have a (or another) biological child was also a significant predictor of higher concerns related with fertility potential for all young women. Higher vigilance regarding reproduction-related cues seems to lead to higher concerns among women with breast cancer history whose fertility is threatened. This result may have important research and clinical implications. Interventions focused on goal-oriented attention self-regulation and problem-solving can help to manage fertility concerns and distress in the course of the disease.

The mediating effect of pleasure and menopausal symptoms on sexual activity among young breast cancer survivors

PURPOSE

Young breast cancer survivors often go through a rapid change in menopause status due to cancer treatment and suffer from abrupt symptoms. This transition compels them to deal with unique medical and psychological side effects on their quality of life. One of the most affected quality of life domains is sexual functioning. This study explored the differences in frequency of sexual activity between young breast cancer survivors and young healthy women. It also examined whether this difference in sexual activity frequency was mediated by discomfort and/or pleasure during intercourse, both of which are affected by symptoms of premature menopause.

METHODS

A total of 97 young breast cancer survivors and 75 young healthy women completed a sociodemographic questionnaire: the Fallowfield's Sexual Activity Questionnaire (FSAQ) and the Menopausal Rating Scale (MRS). Additionally, the breast cancer participants completed a medical data questionnaire.

RESULTS

Findings revealed a significant direct effect between group and menopausal symptoms, menopausal symptoms and pleasure, and pleasure and frequency of sexual activity. Structural equation modeling explained the differences between the groups in frequency of sexual activity as mediated by menopausal symptoms and both pleasure and discomfort.

CONCLUSIONS AND IMPLICATIONS

These results highlight the impact of pleasure on the frequency of young breast cancer survivors' sexual activity, and its relation to menopausal symptoms. These young women should be provided with appropriate information and interventions that will help them experience increased pleasure during sexual activity despite their early and induced menopausal symptoms.

Women's fertility decision-making with a diagnosis of breast cancer: A qualitative evidence synthesis

AIM

To synthesize qualitative evidence of premenopausal women's experiences of fertility decision-making with a diagnosis of breast cancer.

BACKGROUND

Breast cancer is increasingly more common in premenopausal women who may have not yet considered starting a family or have completed their families.

DESIGN

Qualitative evidence synthesis guided by Thomas and Harden's three-stage approach to thematic analysis.

DATA SOURCES

Twelve electronic databases were searched: CINAHL, Embase, Pubmed, Proquest, PsychINFO, Lenus, Scopus, Web of Science, Rian.ie, Medline, EThOS e-theses online and DART Europe. No year limit was set.

REVIEW METHODS

The 'Enhancing transparency in reporting the synthesis of qualitative research guidelines' (ENTREQ) statement was followed.

RESULTS

Fifteen qualitative studies were included in the synthesis. Seven review findings under four major themes were identified: (1) first comes survival, (2) making decisions 'under the gun', (3) health-care professionals should not make assumptions and (4) we want accurate, detailed information and we want it early. High confidence in six of the review findings was agreed.

CONCLUSION

Most women experienced rushed fertility preservation decision-making at a time when they also faced cancer treatment decisions. Women want detailed, clear information on fertility preservation early after their diagnosis.

Expression of lipoma preferred partner in mammary and extramammary Paget disease

BACKGOUND

This study aims to identify the expression of lipoma preferred partner (LPP) in Paget disease (PD) and to further understand the pathogenesis of PD.

METHODS

Tissue microarray was used to evaluate the expression of LPP by immunohistochemistry in 40 PD patients. The results of LPP expression were combined with clinical and histopathological characteristics. Patient files were analyzed retrospectively.

RESULTS

Twenty-one cases were mammary Paget disease (MPD) and 19 extramammary Paget disease (EMPD) involving the vulva, scrotum, and penis. LPP was expressed in PD and this expression was significantly greater in MPD versus EMPD (P = .031). The expression of LPP in MPD was significantly related with age (P = .009) and expression of Ki-67 (P = .011). No statistically significant differences were observed in LPP expression as related to sex, body location, and time of PD diagnosis.

CONCLUSIONS

While LPP is expressed in both MPD and EMPD, the intensity of this expression is greater in MPD. LPP expression is positively correlated with Ki-67 and is more prevalent in middle-aged versus senior MPD patients. Further research is needed to determine its potential role in tumorigenesis and distribution.

Differences in Breast Cancer Stage at Diagnosis by Ethnicity, Insurance Status, and Family Income in Young Women in the USA

PURPOSE

Describe the clinical and epidemiological data from young women with breast cancer and determine the association between ethnicity, insurance status, family income, and breast cancer stage at the diagnosis in this population.

METHODS

Women under the age of 40 diagnosed with invasive breast cancer from 2010 to 2014 and identified in the Surveillance, Epidemiology, and End Results (SEER) 18 registries database were included. Binary logistic regression was applied in order to estimate the odds ratios (ORs) for factors that were potentially predictive for receiving a breast cancer diagnosis at stage I.

RESULTS

Of 14,379 young women with invasive breast cancer, 70.9% of the patients were white, 15.9% black, and 13.2% classified as other ethnicity (American Indian, Asian, Pacific Islander). The initial clinical stage at diagnosis was stage I in 28.2%, II in 45.2%, III in 19.0%, and IV in 7.6%. The chi-square test showed a significant association between clinical stage at diagnosis and family income (p < 0.0001), insurance status (p < 0.0001), and ethnicity (p < 0.0001). The ORs for being diagnosed at stage I, regarding different factors, revealed that women with family income higher than US$ 85,000 were more likely to be diagnosed with stage I (OR [95%CI], 1.306 [1.173-1.454]; p value < 0.0001) when compared with patients with family income of less than US$ 60,000. Black women were less likely to be diagnosed with stage I (OR [95%CI], 0.676 [0.605-0.755]; p value < 0.0001), when compared with white women. Uninsured women were less likely to be diagnosed with stage I (OR [95%CI], 0.586 [0.529-0.648]; p value < 0.0001) when compared with women with insurance coverage.

CONCLUSION

Among young US women diagnosed with invasive breast cancer, most of them presented early stage disease. Women with black ethnicity, low income, and uninsured are at risk for late-stage presentation. Improvements in strategies to allow earlier breast cancer diagnosis in these at risk population are urged.

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.
