Abstract
The onset of pregnancy marks the start of offspring development, and represents the key physiological event that induces re-organization and specialization of breast tissue. Such drastic tissue remodeling has also been linked to epithelial cell transformation and the establishment of breast cancer (BC). While patient outcomes for BC overall continue to improve across subtypes, prognosis remains dismal for patients with gestational breast cancer (GBC) and post-partum breast cancer (PPBC), as pregnancy and lactation pose additional complications and barriers to several gold standard clinical approaches. Moreover, delayed diagnosis and treatment, coupled with the aggressive time-scale in which GBC metastasizes, inevitably contributes to the higher incidence of disease recurrence and patient mortality. Therefore, there is an urgent and evident need to better understand the factors contributing to the establishment and spreading of BC during pregnancy. In this review, we provide a literature-based overview of the diagnostics and treatments available to patients with BC more broadly, and highlight the treatment deficit patients face due to gestational status. Further, we review the current understanding of the molecular and cellular mechanisms driving GBC, and discuss recent advances in model systems that may support the identification of targetable approaches to block BC development and dissemination during pregnancy. Our goal is to provide an updated perspective on GBC, and to inform critical areas needing further exploration to improve disease outcome.

Abstract
The management of cancer during pregnancy requires a patient-centered, multidisciplinary approach to balance maternal and fetal well-being given the rarity of this clinical scenario and lack of substantial data. Involvement of oncology and nononcology medical specialists and ethical, legal, and psychosocial supports, as needed, is instrumental in navigating the complexities of care for this patient population. Critical periods of fetal development and physiological changes in pregnancy must be considered when planning diagnostic and therapeutic approaches during pregnancy. The complexity of symptom recognition and interventional approaches contributes to diagnostic delays of cancers during pregnancy. Ultrasound and whole-body diffusion-weighted magnetic resonance imaging are safe throughout pregnancy. Surgery can be safely performed throughout pregnancy, with the early second trimester preferred for intra-abdominal surgery. Chemotherapy can be safely administered after 12-14 weeks of gestation until 1-3 weeks before the anticipated delivery. Most targeted and immunotherapeutic agents are contraindicated during pregnancy because of limited data. Pelvic radiation during pregnancy is absolutely contraindicated, while if radiation to the upper body is needed, administration should only be considered early in pregnancy. To ensure that the total cumulative fetal exposure to ionizing radiation does not exceed 100 mGy, early inclusion of the radiology team in the care plan is required. Closer prenatal monitoring is recommended for maternal and fetal treatment-related toxicities. Delivery before 37 weeks of gestation should be avoided if possible, and vaginal delivery is preferred unless obstetrically indicated or specific clinical scenarios. Postpartum, breastfeeding should be discussed, and the neonate should receive blood work to assess for acute toxicities with follow-up arranged for long-term monitoring.

Abstract
Prompt diagnosis of cancer in pregnancy is necessary to ensure timely management and improve outcomes. However, there are a several reasons why diagnosis may be delayed in pregnancy. Three major contributors to delayed diagnosis and treatment are patient delay, provider delay, and referral delay. This article aims to (1) increase physician awareness of this problem by providing a detailed review of the main culprits of delayed diagnosis and treatment of cancer in the pregnant patient, (2) discuss the complex ethical issues at hand in these cases, and (3) provide suggestions on how to better address such cases with the goal of improving patient outcomes.

Abstract
Breast cancer is a common type of cancer diagnosed during pregnancy, with increasing incidence over the last years, as more women choose to delay childbearing. Compared to breast cancer in general population, pregnancy-associated breast cancer (PABC) is significantly different in its terms of epidemiology, diagnostic and therapeutic management, while it exhibits particularly aggressive behavior, deriving from its unique molecular and biological profile. Although not fully elucidated, the pathophysiological basis of PABC can be traced back to a combination of hormonal and immune changes during pregnancy, breast involution and altered gene expression. There is considerable controversy in the existing literature about the influence of PABC on pregnancy outcomes, regarding both short- and long-term effects on maternal and fetal/neonatal health. The majority of PABC patients have advanced-stage disease at initial diagnosis and face a significantly poorer prognosis, with decreased survival rates. The most commonly reported adverse obstetrical–fetal events are preterm delivery and prematurity-associated neonatal morbidity, while other neonatal treatment-associated complications might also occur, even when safe therapeutic options are applied during pregnancy. The objective of the present comprehensive review was to summarize current knowledge and up-to-date evidence about the pathophysiological, molecular and biological basis of PABC, as well as its association with adverse maternal, obstetrical, fetal and neonatal outcomes.

Abstract
The breast experiences substantial changes in morphology and function during pregnancy and lactation which affects its imaging properties and may reduce the visibility of a concurrent pathological process. The high incidence of benign gestational-related entities may further add complexity to the clinical and radiological evaluation of the breast during the period. Consequently, pregnancy-associated breast cancer (PABC) is often a delayed diagnosis and carries a poor prognosis. This state-of-the-art pictorial review illustrates how despite currently being underutilized, technical advances and new clinical evidence support the use of unenhanced breast MRI during pregnancy and both unenhanced and dynamic-contrast enhanced (DCE) during lactation, to serve as effective supplementary modalities in the diagnostic work-up of PABC.

Abstract
Breast cancer diagnosed during pregnancy poses ethical and professional challenges. Clinical management of that condition should ensure the safety of both the mother and fetus. Clinical trials on breast cancer exclude pregnant women, so sufficient evidence with which to formulate guidelines for the management of these patients is lacking. Failing to undergo a breast examination during pregnancy, breast symptoms explained by physiological changes such as pregnancy, and unnecessary abortions after the diagnosis of breast cancer lead to worse outcomes for these patients. Multidisciplinary teams including breast surgeons, obstetricians, radiologists, pathologists, and anesthesiologists need to make an early diagnosis and comprehensively evaluate patients in different gestational weeks and with different stages of breast cancer in order to optimize outcomes.

Abstract
Breast cancers that occur in young women up to 5 to 10 years' postpartum are associated with an increased risk for metastasis and death compared with breast cancers diagnosed in young, premenopausal women during or outside pregnancy. Given the trend to delay childbearing, this frequency is expected to increase. The (immuno)biology of postpartum breast cancer is poorly understood and, hence, it is unknown why postpartum breast cancer has an enhanced risk for metastasis or how it should be effectively targeted for improved survival. The poorer prognosis of women diagnosed within 10 years of a completed pregnancy is most often contributed to the effects of mammary gland involution. We will discuss the most recent data and mechanistic insights of the most important processes associated with involution and their role in the adverse effects of a postpartum diagnosis. We will also look into the effect of lactation on breast cancer outcome after diagnosis. In addition, we will discuss the available treatment strategies that are currently being used to treat postpartum breast cancer, keeping in mind the importance of fertility preservation in this group of young women. These additional insights might offer potential therapeutic options for the improved treatment of women with this specific condition.

Abstract
Breast mass is one of the clinical signs of breast lesions. Clinically, breast tumors can occur in breast cancer, breast tuberculosis, breast duct dilatation, breast cysts, breast fibroadenoma, and breast hyperplasia. Its pathogenesis is not clear. The occurrence of breast lesions is
related to many factors, such as diet, trauma, genetic mutations, inheritance, endocrine disorders, breast development, and chronic stimuli. With the continuous improvement of examination equipment and continuous improvement of the treatment level, the incidence of breast masses is increasing.
For a long time, clinicians have mostly used hand palpation methods to complete the diagnosis of breast masses based on the relatively hard properties of breast masses and adjacent tissues. It is more difficult to diagnose patients based on their clinical symptoms and signs, and it is easy
to miss the diagnosis. Choosing the appropriate diagnostic method to confirm breast mass disease has become the first task for the diagnosis and treatment of breast mass. Ultrasound elastography is a new ultrasound examination method. It diagnoses the elasticity and hardness of breast masses
by using corresponding characteristics. The imaging principle is to apply pressure to the tissue at the lesion site to determine its elasticity and hardness to identify the nature of the tumor. This article explores the clinical value of ultrasound elastography in the effective diagnosis of
breast masses. Compared with the diagnosis results of ordinary ultrasound, the parameters such as the position, shape, size, boundary, internal echo, and rear echo of the focused mass were observed. Facts have proved that elastography can be used to make a qualitative differential diagnosis
of benign and malignant breast masses from another angle according to the different characteristics of the hardness of the tissue being examined. It is non-invasive, non-radiative, low-cost, and easy for patients to accept. Provide valuable clinical diagnosis basis for early detection and
treatment of breast masses.

Abstract
Introduction The frequency of breast cancer (BC) is increasing among Pakistani females. It has been estimated that one out every nine women is predicted to develop BC, which is the highest disease occurring rate in the Asian population. The study aimed to evaluate the factors responsible for delay in diagnosis of BC in Sindh, Pakistan. Methodology This study was conducted at the Medical Oncology Department of Jinnah Postgraduate Medical Center Karachi from December 2018 to June 2019. All women between 17 and 80 years diagnosed with BC who had treatment delay of more than six months were included in the study using a non-probability consecutive sampling technique. The face-to-face interviews were conducted by the researcher himself and all the data regarding demographics and factors related to treatment delay of BC was noted in a structured questionnaire. Data were analyzed using SPSS version 23 (IBM Corp., Armonk, NY). Results Appointment delay was significantly associated with a treatment-seeking delay in patients (p=0.03). Lack of awareness was another significant factor associated with treatment delay in BC patients. About 50 (70.4%) women who reported a lack of awareness sought treatment after 10 months of their first onset of symptoms (p=0.001). Cultural beliefs were a significant cause of treatment delay of 10-12 months in 71.8% of patients (p=0.021). Financial constraints significantly correlated with treatment delay (p=0.015). Conclusion The cultural beliefs, poor financial status, and lack of awareness are the significant factors for the treatment delay in BC patients. Promoting female health awareness can tackle many of these issues.

Abstract
Breast and cervical cancers comprise 50% of all cancers during pregnancy. In particular, gestational breast cancer is considered one of the most aggressive types of cancers, which is a rare but fatal disease. However, the incidence of this type of cancer is increasing over the years and its prevalence is expected to rise further as more women delay childbearing. Breast cancer occurring after pregnancy is generally triple negative with specific characterizations of a poorer prognosis and outcome. On the other hand, it has been pointed out that this cancer is associated with a specific group of genes which can be used as precise targets to manage this deadly disease. Indeed, combination therapies consisting of gene-based agents with other cancer therapeutics is presently under consideration. We herein review recent progress in understanding the development of breast cancer during pregnancy and their unique subtype of triple negative which is the hallmark of this type of breast cancer.

Abstract
More women are delaying child-birth. Thus, the diagnosis of pregnancy-associated breast cancer (PABC) will continue to increase. The aim of this study was to identify core candidate genes of PABC, and the relevance of the genes on the prognosis of PABC. GSE31192 and GSE53031 microarray profile datasets were downloaded from the Gene Expression Omnibus database and differentially expressed genes were analyzed using the R package and GEO2R tool. Then, Gene Ontology and Kyoto Encyclopedia of Gene and Genome pathway enrichment analyses were performed using the Database for Annotation, Visualization, and Integrated Discovery. Moreover, the Search Tool for the Retrieval of Interacting Genes and the Molecular Complex Detection Cytoscape software plug-in were utilized to visualize protein–protein interactions and to screen candidate genes. A total of 239 DEGs were identified in PABC, including 101 up-regulated genes mainly enriched in fatty acid activation and the fibroblast growth factor signaling pathway, while 138 down-regulated genes particularly involved in activation of DNA fragmentation factor and apoptosis-induced DNA fragmentation. Fourteen hub genes with a high degree of connectivity were selected, including CREB1, ARF3, UBA5, SIAH1, KLHL3, HECTD1, MMP9, TRIM69, MEX3C, ASB6, UBE2Q2, FBXO22, EIF4A3, and PXN. Overall survival (OS) analysis of core candidate genes was performed using the Gene Expression Profiling Interactive Analysis and UALCAN websites. High ASB6 expression was associated with worse OS of PABC patients. Molecular subtypes and menopause status were also associated with worse OS for PABC patients. In conclusion, ASB6 could be a potential predictor and therapeutic target in patient with PABC.

Abstract
Background Women with pregnancy-associated breast cancer (PABC), i.e. diagnosed during or within 2 years of pregnancy, have a poor prognosis. We compared symptoms, diagnostics, treatments, and waiting times from first symptoms to treatment initiation in women diagnosed with PABC and non-PABC. Materials and methods Women diagnosed with PABC and non-PABC at ages 15–44 were identified in Swedish healthcare registers. Chart information was retrieved for 546 women (273 PABC cases and 273 age- and hospital-matched non-PABC controls) treated at 11 hospitals across Sweden between 1992 and 2009. Distributions of symptoms, diagnostics and treatments were compared. Median waiting times from initial symptoms to start of treatment, and time periods within, were estimated from Kaplan–Meier curves. Results Initial symptoms in women with PABC and non-PABC were similar. Women with PABC more often underwent biopsy and ultrasound than mammography at initial examination. Compared to non-PABC, rates of mastectomy and axillary clearance were higher in women with PABC, while endocrine treatment was less common. The time from symptoms to first healthcare contact was non-significantly longer in women diagnosed during or within 6 months of pregnancy. Waiting times from contact with healthcare to diagnosis and treatment were shorter or similar in women with PABC compared to women with non-PABC. Conclusions These findings do not support the notion that diagnostic and treatment delays following a first healthcare contact are more common in women diagnosed with breast cancer during or shortly after pregnancy. However, there was some evidence of delays in seeking healthcare among pregnant and lactating women.

Abstract
The incidence of pregnancy-associated breast cancer (PABC) increases as more women choose to delay childbearing and the population-based incidence of breast cancer rises. Reliably and safely staging PABC is necessary to choose between starting with local or systemic therapy. With regard to local therapy, both lumpectomy and mastectomy can be considered depending on gestational age and the stage at diagnosis. By mirroring nonpregnant treatment regimens as much as possible, chemotherapy may improve long-term oncologic outcomes while allowing for surgical downstaging during pregnancy. Delaying treatment due to misconceptions regarding risk of local and systemic therapy most certainly worsens oncologic outcomes, and most neonatal morbidity is related to gestational age at delivery and not in utero exposures. Pregnancy itself was once considered an independent risk factor for worse outcome, but the prognosis of these patients is not significantly different than nonpregnant counterparts of a similar age.

Pregnancy-associated breast cancer in rural Rwanda: the experience of the Butaro Cancer Center of Excellence. BMC Cancer 2018; 18:634. [PMID: 29866062 PMCID: PMC5987575 DOI: 10.1186/s12885-018-4535-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2017] [Accepted: 05/21/2018] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Breast cancer is the most common malignancy encountered during pregnancy. However, the burden of pregnancy-associated breast cancer (PABC) and subsequent care is understudied in sub-Saharan Africa (SSA). Here, we describe the characteristics, diagnostic delays and treatment of women with PABC seeking care at a rural cancer referral facility in Rwanda. METHODS Data from female patients aged 18-50 years with pathologically confirmed breast cancer who presented for treatment between July 1, 2012 and February 28, 2014 were retrospectively reviewed. PABC was defined as breast cancer diagnosed in a woman who was pregnant or breastfeeding. Numbers and frequencies are reported for demographic and diagnostic delay variables and Wilcoxon rank sum and Fisher's exact tests are used to compare characteristics of women with PABC to women with non-PABC at the alpha = 0.05 significance level. Treatment and outcomes are described for women with PABC only. RESULTS Of the 117 women with breast cancer, 12 (10.3%) had PABC based on medical record review. The only significant demographic differences were that women with PABC were younger (p = 0.006) and more likely to be married (p = 0.035) compared to women with non-PABC. There were no significant differences in diagnostic delays or stage at diagnosis between women with PABC and women with non-PABC women. Eleven of the women with PABC received treatment, three had documented treatment delays or modifications due to their pregnancy or breastfeeding, and four stopped breastfeeding to initiate treatment. At the end of the study period, six patients were alive, three were deceased and three patients were lost to follow-up. CONCLUSIONS PABC was relatively common in our cohort but may have been underreported. Although patients with PABC did not experience greater diagnostic delays, most had treatment modifications, emphasizing the potential value of PABC-specific treatment protocols in SSA. Larger prospective studies of PABC are needed to better understand particular challenges faced by these patients and inform policies and practices to optimize care for women with PABC in Rwanda and similar settings.

Abstract
Background: Cancer is a major public health problem. Early diagnosis and treatment are essential for reducing mortality. This study aimed to analyze factors associated with delay in breast cancer diagnosis and treatment among women attending a reference cancer service. Methods: This retrospective, cross-sectional study was performed with data collected from medical records and interviews conducted with women diagnosed with breast cancer and treated from October 2013 to October 2014 at a cancer reference hospital in Paraná, Southern Brazil. Results: A total of 82 participants were enrolled during the study period; their average age was 58.2 ± 11.5 years. The average time taken for final diagnosis of breast cancer was 102.5 ± 165.5 days. Treatment onset was delayed in the majority of cases, and the average time elapsing from diagnostic biopsy to onset of primary treatment was 72.3 ± 54.0 days. The odds of treatment delay were higher among the women with a low educational level. Conclusions: The results underline the need for proposals aimed at early detection, identification of risk factors and timely provision of treatment by health managers that focus on this group.

Abstract
Pregnancy-associated breast cancer (PABC) is defined as breast cancer that occurs during pregnancy or within one year of delivery. PABCs are typically found at advanced stage and are reported to have higher recurrence and mortality rates as compared to non PABC. Although it is said to be rare its incidence is increasing. Very little data is available on PABC among Indian women. Delay in diagnosis is one of the major causes of aggressive presentation of PABC. This is due to the fact that most of the lesions presenting during this period are benign and lactational changes hamper the detection of mass clinically as well as by various investigative methods. Paget's disease of breast, usually reported in elderly woman, when occurs in lactating breast may mimic benign eczematous lesion. Increased awareness among patients as well as clinicians is required to detect this highly aggressive form of breast cancer at an early and treatable stage. Treatment is by multidisciplinary approach and depends upon the gestational stage. Here we report a case of PABC in a lactating woman presenting with Paget's disease because such case may be under diagnosed as breast feeding related lesion leading to delayed diagnosis.

Abstract
In our study, we sought to report the management, clinical outcomes, and follow-up rates of patients who presented for evaluation of breast abscess in the Emergency Department (ED) after hours. A retrospective search of ultrasound reports at our institution identified all patients from January 1, 2009 to June 30, 2013 who were scanned in the ED after hours to evaluate for breast abscess. Patient demographics, clinical information, imaging findings, follow-up rates, and outcomes were reviewed. One hundred eighty-five patients were included in the study. Forty-four percent (86/185) of the patients were diagnosed with abscess based on ultrasound findings in the ED. Twenty-seven percent (23/86) were recently post-operative, and 12 % (10/86) were postpartum/breastfeeding. Mastitis was the diagnosis in the remaining 54 % (99/185). Only 1/86 cases were associated with breast cancer. Seventy-seven percent (66/86) of patients were treated with an invasive procedure; 39 % (26/66) had surgical evacuation, 30 % (20/66) image-guided drainage, 23 % (15/66) bedside or clinic incision and drainage, and 8 % (5/66) palpation-guided fine needle aspiration (FNA). Seventy-seven percent (143/185) of patients had clinical and/or imaging follow-up. Forty-four percent (63/143) had long-term follow-up (≥ 3 months). Almost 50 % of the patients who presented to the ED for evaluation of abscess were diagnosed with abscess while the remaining patients were diagnosed with mastitis. Appropriate clinical and/or imaging follow-up occurred in 77 %. Long-term follow-up (≥ 3 months) occurred more frequently in patients older than 30 years of age. Appropriate follow-up does not occur in approximately one fourth of cases, suggesting that additional clinician and patient education is warranted.
