Abstract
PURPOSE To select patients who would benefit most from sentinel lymph node biopsy (SLNB) by investigating the characteristics and risk factors of axillary lymph node metastasis (ALNM) in microinvasive breast cancer (MIBC). METHODS This retrospective study included 1688 patients with MIBC who underwent breast surgery with axillary staging at the Asan Medical Center from 1995 to 2020. RESULTS Most patients underwent SLNB alone (83.5%). Seventy (4.1%) patients were node-positive, and the majority had positive lymph nodes < 10 mm, with micro-metastases occurring frequently (n = 37; 55%). Node-positive patients underwent total mastectomy and axillary lymph node dissection (ALND) more than breast-conserving surgery (BCS) and SLNB compared with node-negative patients (p < 0.001). In the multivariate analysis, independent predictors of ALNM included young age [odds ratio (OR) 0.959; 95% confidence interval (CI) 0.927-0.993; p = 0.019], ALND (OR 11.486; 95% CI 5.767-22.877; p < 0.001), number of lymph nodes harvested (≥ 5) (OR 3.184; 95% CI 1.555-6.522; p < 0.001), lymphovascular invasion (OR 6.831; 95% CI 2.386-19.557; p < 0.001), presence of multiple microinvasion foci (OR 2.771; 95% CI 1.329-5.779; p = 0.007), prominent lymph nodes in preoperative imaging (OR 2.675; 95% CI 1.362-5.253; p = 0.004), and hormone receptor positivity (OR 2.491; 95% CI 1.230-5.046; p = 0.011). CONCLUSION Low ALNM rate (4.1%) suggests that routine SLNB for patients with MIBC is unnecessary but can be valuable for patients with specific risk factors. Ongoing trials for omitting SLNB in early breast cancer, and further subanalyses focusing on rare populations with MIBC are necessary.

Abstract
Advances in the treatment of older women with early-stage breast cancer, particularly opportunities for de-escalation of therapy, have afforded patients and providers opportunity to individualize care. As the majority of women ≥65 have estrogen receptor-positive, HER2-negative disease, locoregional therapy (surgery and/or radiation) may be tailored based on a patient's physiologic age to avoid either over- or undertreatment. To determine who would derive benefit from more or less intensive therapy, an accurate assessment of an older patient's physiologic age and incorporation of patient-specific values are paramount. While there now exist well-validated geriatric assessment tools whose use is encouraged by the American Society of Clinical Oncology when considering systemic therapy, these instruments have not been widely integrated into the locoregional breast cancer care model. This review aims to highlight the importance of assessing frailty and the concepts of and over- and undertreatment, in the context of trial data supporting opportunities for safe deescalation of locoregional therapy, when treating older women with early-stage breast cancer.

Abstract
INTRODUCTION Breast cancer in older women tends to have more favourable biology, compared to younger women. Androgen receptor (AR) is significant for breast tumour carcinogenesis; however, the role of AR in older women has not been fully explored. METHODS Surgical specimens were obtained from an existing series of 1758 older women (≥ 70 years) with primary breast cancer, treated in a single institution with long-term (≥ 37 years) follow-up. As part of previous work, it was possible to construct good quality tissue microarrays (TMAs) in 575 surgical specimens and a panel of 24 biomarkers was measured by immunohistochemistry (IHC) in these TMAs. AR positivity was assessed by IHC and defined as H-score ≥ 40. The relationship between AR in this cohort was compared to an equivalent group of younger women (< 70 years, n = 1708); the panel of 24 biomarkers and breast cancer specific survival (BCSS) in the older cohort. RESULTS AR was assessed in 509 samples. Overall, 59% of the older women cohort had positive expression of AR, compared to 63% in the younger cohort. AR positivity (regardless of age) was associated with smaller size of tumour, lower grade of tumour, lower tubule formation, lower nuclear polymorphism and lower mitotic frequency. AR positivity was associated with positive expression of oestrogen receptor (ER), progesterone receptor (PR), breast cancer gene 1 (BRCA1), cytokeratin (CK) 7/8, CK18, CK19, B cell lymphoma (Bcl)2 and Mucin 1 (Muc1) expression. Conversely, AR-positive expression was associated with negative expression of human epidermal growth factor receptor 2 (HER2), Ki-67, CK5, CK17, epidermal growth factor receptor (EGFR), and CD44 expression. Older women with AR-positive tumours had better BCSS compared to AR-negative tumours (p = 0.009). CONCLUSIONS There was no difference in AR expression between older and younger women with breast cancer. AR has prognostic potential in terms of BCSS. Further work is needed to investigate AR as a therapeutic target.

Characteristics and chronologically changing patterns of late-onset breast cancer in Korean women of age ≥ 70 years: A hospital based-registry study. BMC Cancer 2022; 22:1261. [PMID: 36471272 PMCID: PMC9720951 DOI: 10.1186/s12885-022-10295-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Accepted: 11/08/2022] [Indexed: 12/07/2022] Open
Abstract
BACKGROUND Women from Asian and western countries have vastly different ages of onset of breast cancer, with the disease tending to occur at an older age in the West. Through an investigation of the patterns of old-onset breast cancer (OBC) in Korean women, we aimed to identify the characteristics of Korean OBC and evaluate whether these patterns are changing in relation to increasing westernization. METHODS This study retrospectively evaluated 102,379 patients who underwent surgical treatment of primary breast cancer between January 1, 2000 and December 31, 2013 in Korea. We used hospital -based breast cancer registry and analyzed data from these patients using multiple linear regression analysis to compare the characteristics and chronologically changing patterns between OBC (70 years of age or older) and non-OBC (40-69 years of age) patients in Korea. RESULTS A total of 6% of the 102,379 patients had OBC. Overall, OBC had more favorable biological features, such as a higher incidence of luminal A subtype, than did non-OBC, except for a higher incidence rate of triple-negative breast cancer (TNBC). However, OBC also presented with a higher overall disease stage, including higher T and M stages. Although the incidence rates of both OBC and non-OBC have increased overtime, the relative proportion of OBC patients has slightly increased, whereas that of non-OBC has slightly decreased. The increase in the incidence of both OBC and non-OBC was primarily due to the luminal A subtype. CONCLUSIONS Based on a hospital-based registry, overall, Korean OBC had favorable biological features but showed a higher rate of TNBC and advanced cancer stages. The incidence trend of breast cancer in Korea is slowly shifting toward an older age at onset, largely due to the luminal A subtype. Our results may provide novel insights into OBC in Asia, and aid in the development of optimal management of the disease in Asia. TRIAL REGISTRATION Retrospectively registered.

J Cancer Res Clin Oncol 2021; 148:387-400.

Abstract
Background We explored the hypothesis that high-quality standards in diagnostic mammography can lead to an early diagnosis of breast cancers and identifies at risk populations outside screening programs. The histopathological features and distribution of the TNM classification were examined in relation to patient age in a large group of women with breast cancers participating in the Quality Assured Mamma Diagnostic (QuaMaDi) program of the state of Schleswig–Holstein. Patients and methods Surgical pathological reports were studied for clinicopathological characteristics, receptor status, molecular subtype and tumor stage. The analysis was conducted by dividing the study population into three age groups: women under 50 years (pre-screening), 50–69 years (peri-screening) and over 70 years (post-screening). Results 7.111 biopsies and 2.887 resection specimens were included. Breast cancer was diagnosed in 4.241 (59.7%) cases, one fourth of them in women < 50 years. Elderly women (> 70 years) had more well-differentiated, estrogen receptor (ER)-positive and HER2-negative carcinomas, whereas younger women (< 50 years) tended to have more poorly differentiated, ER negative, and HER2-positive carcinomas. 47% of breast carcinoma were luminal B tumors and were most common regardless of age. 70.4% of resected specimen had pT1 stage. Nodal negative were 71.2%. Conclusion In QuaMaDi breast cancer was diagnosed at an early and potentially curable stage of the disease due to high-quality standards in diagnostic mammography. In addition, regardless of age, an increased number of prognostically unfavorable molecular subtypes were detected. Thus, QuaMaDi helps to identify at risk populations. QuaMaDi significantly improves diagnostic mammography and complements mammography screening programs.

Abstract
Purpose There are numerous biomarkers which may have potential predictive and prognostic significance in breast cancer. This is extremely important in older adults, who may opt for less aggressive therapy. This work outlines the literature on biological assessment outside of standard biomarkers (defined as ER, PgR, HER2, Ki67) in women ≥ 65 years with primary operable invasive breast cancer, to determine which additional biomarkers are relevant to outcome in older women. Methods Medline and Embase databases were searched. Studies were eligible if included ≥ 50 patients aged ≥ 65 years; stratified results by age; measured a biomarker outside of standard assay and reported patient data. Results A total of 12 studies were appraised involving 5000 patients, measuring 28 biomarkers. The studies were extremely varied in methodology and outcome but three themes emerged: 1. Differences in biomarker expression between younger and older women, indicating that breast cancer in older women is generally less aggressive compared to younger women; 2. Relationship of biomarker expression with survival, suggesting biomarkers which may exclusively predict response to primary treatment in older women; 3. Association of biomarker with chemotherapy, suggesting that older patients should not be declined chemotherapy based on age alone. Conclusion There is evidence to support further investigation of B-cell lymphoma (BCL2), liver kinase (LK)B1, epidermal growth factor receptor (EGFR), cytoplasmic cyclin-E, mucin (MUC)1 and cytokeratins (CKs) as potential predictive or prognostic markers in older women with breast cancer undergoing surgery. Studies exploring these biomarkers in larger cohorts and in women undergoing non-operative therapies are required.

Abstract
BACKGROUND With an aging society, Korean women ≥70 years of age are increasingly being diagnosed with breast cancer. OBJECTIVE To investigate the clinicopathological and biological characteristics of breast cancer in elderly Korean women and compare them with breast cancer in elderly (≥70 years) women globally and in Korean women of all ages. METHODS We retrospectively reviewed the clinicopathological and biological features of breast cancer in elderly Korean women (≥70 years; n = 87) who sought treatment during 2004-2014 from a single institution. These data were indirectly compared with data of Korean women of all ages (nationwide Korean Breast Cancer Registry) or elderly women globally (meta-analysis). RESULTS Compared to elderly women with breast cancer globally, Korean elderly women had a more symptomatic presentation, lower ER expression, and overexpression or amplification of human epidermal growth factor receptor 2. Compared to Korean women of all ages with breast cancer, elderly Korean women presented with advanced tumor stages, larger tumor size, more lymph node involvement, and more luminal B and basal-like subtypes. CONCLUSIONS Breast cancer had a more aggressive clinicopathological and biological characteristics in elderly Korean women than in Korean women of all ages or elderly women globally.

Abstract
Simple Summary Breast cancer incidence not only increases with advancing age but also changes its biology. This study was conducted to understand aging related change in the biological characteristics of breast cancer. The results highlighted that the change occurs in a gradual fashion, where 40 years and 70 years become the milestones for significant difference. Breast cancer in patients <40 years showed aggressive characteristics while at 70 years and above they are more indolent. The molecular pattern between 40 years and 70 years appears to be a transition from aggressive to less aggressive phenotypes. This change in the biology of the breast cancer significantly influences clinical outcome. Abstract As age advances, breast cancer (BC) tends to change its biological characteristics. This study aimed to explore the natural progression of such changes. The study included 2383 women with clinically T0-2N0-1M0 BC, managed by primary surgery and optimal adjuvant therapy in a dedicated BC facility. Tissue micro-arrays were constructed from their surgical specimens and indirect immunohistochemistry was used for analysis of a large panel (n = 16) of relevant biomarkers. There were significant changes in the pattern of expression of biomarkers related to luminal (oestrogen receptor (ER), progesterone receptors (PgR), human epidermal growth factor receptor (HER-2), E-cadherin, MUC1, bcl2 CK7/8, CK18 and bcl2) and basal (CK5/6, CK14, p53 and Ki67) phenotypes, lymph node stage, histological grade and pathological size when decade-wise comparison was made (p < 0.05). The ages of 40 years and 70 years appeared to be the milestones marking a change of the pattern. There were significantly higher metastasis free and breast cancer specific survival rates among older women with ER positive tumours while there was no significant difference in the ER negative group according to age. Biological characteristics of BC show a pattern of change with advancing age, where 40 years and 70 years appear as important milestones. The pattern suggests <40 years as the phase with aggressive phenotypes, >70 years as the less aggressive phase and 40–70 years being the transitional phase.

Abstract
A move is under way towards personalised cancer treatment, where tumour biology of an individual patient is examined to give unique predictive and prognostic information. This is extremely important in the setting of older women, who have treatment-specific goals which may differ from their younger counterparts, and may include conservation of quality of life rather than curative intent of treatment. One method employed to assist with this is the use of tumour-based prognostic and predictive tools. This article explores six of the most common tumour-based tools currently available on the market: MammaPrint, Oncotype DX, Mammostrat, Prosigna, EndoPredict, IHC4. The article discusses the creation and validation of these tools, their use and validation in older women, and future directions in the field. With the exception of Oncotype Dx, which has also been licensed for prediction of response from adjuvant chemotherapy, these tools have been licensed for use as prognostic tools only, mainly in the setting of adjuvant therapy following surgery. The evidence base for use in older women is strongest for Mammostrat and PAM50, although overall the evidence is much weaker than that in younger women. Where older women have been included in validation studies, this is often in small numbers, or the exact proportion of older women is unknown. In practice, all six of the tools are recommended to be utilised on surgical excision specimens, as well as in core needle biopsy (CNB) specimens in all of the tools except Mammostrat. This is extremely important in the setting of older women, of whom a large proportion do not undergo surgery. The suggested nature of the sample is formalin-fixed paraffin-embedded in all the tools except MammaPrint, which can also be performed on fresh-frozen samples. Future development of prognostic tools in older women with breast cancer should focus on treatment dilemmas specific to this population. This includes the decision of primary treatment between surgery or endocrine therapy and decisions regarding adjuvant therapy, in particular, chemotherapy.

Patterns of biomarker expression in patients treated with primary endocrine therapy - a unique insight using core needle biopsy tissue microarray. Breast Cancer Res Treat 2020; 185:647-655. [PMID: 33226492 PMCID: PMC7921046 DOI: 10.1007/s10549-020-06023-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 11/13/2020] [Indexed: 12/12/2022]
Abstract
Purpose Prediction of response to primary endocrine therapy (PET) in older women is based on measurement of oestrogen receptor (ER), progesterone receptor (PgR) and human epidermal growth factor (HER)-2. This study uses a unique method for construction of core needle biopsy (CNB) tissue microarray (TMA), to correlate expression of a panel of 17 biomarkers with clinical outcome, in patients receiving PET. Methods Over 37 years (1973–2010), 1758 older (≥ 70 years) women with operable primary breast cancer were managed in a single institution. Of these, 693 had sufficient good-quality CNB to construct TMA, of which 334 had ER-positive tumours treated by PET with a minimum of 6-month follow-up. A panel of biomarkers was measured by immunohistochemistry (ER, PgR, HER2, Ki-67, p53, CK5/6, CK 7/8, EGFR, BCL-2, MUC1, VEGF, LKB1, BRCA1, HER3, HER4, PTEN and AIB1). Expression of each biomarker was dichotomised into ‘low’ or ‘high’ based on breast cancer-specific survival (BCSS). Results From the panel of biomarkers, multivariate analysis showed:High ER (p = 0.003) and PgR (p = 0.002) were associated with clinical benefit of PET at 6 months, as opposed to progressive disease. High ER (p = 0.0023), PgR (p < 0.001) and BCL-2 (p = 0.043) and low LKB1 (p = 0.022) were associated with longer time to progression. High PgR (p < 0.001) and low MUC1 (p = 0.021) were associated with better BCSS.
Expression of other biomarkers did not show any significant correlation. Conclusions In addition to ER and PgR; MUC1, BCL-2 and LKB1 are important in determining the outcome of PET in this cohort.

Abstract
INTRODUCTION Controversy over the need for sentinel node biopsy (SNB) continues to exist for the optimal treatment of breast cancer in patients ≥ 70 years of age, especially in those with lower-risk disease. Clinicians must balance competing risks to give the best individualized care. METHODS The American Society of Breast Surgeons (ASBrS) conducted a debate discussing the pros and cons of routinely performing SNB in this age group. Small, randomized studies have been conducted that show no overall survival benefit to axillary intervention (either axillary dissection or SNB) in patients with clinically T1N0 estrogen receptor (ER)- and progesterone receptor (PR)-positive, HER2/neu-negative tumors. There may be a small local recurrence benefit to axillary staging in patients who do not undergo radiation. Alternatively, axillary ultrasound, which carries a low false-negative rate for heavy disease burden, can be used to select patients who can avoid SNB. CONCLUSION Surgeons must continue to individualize care of breast cancer patients over 70 years of age in whom competing comorbidities may dictate care. No randomized clinical trials (RCTs) have found a survival benefit to axillary staging in this low-risk population. However, in healthy patients, axillary staging may improve local control, provide prognostic information, and help guide decisions regarding adjuvant therapy such as chemotherapy and radiation. Ongoing RCTs are evaluating the benefit of SNB in patients with a negative axillary ultrasound. Until those results are available, clinicians and patients must balance the risk and benefits to determine if SNB adds significant value to their overall care.

Routine treatment and outcome of breast cancer in younger versus elderly patients: results from the SENORA project of the prospective German TMK cohort study. Breast Cancer Res Treat 2017; 167:567-578.

Abstract
Purpose There is an ongoing discussion about ‘undertreatment’ of breast cancer in elderly patients. Due to low accrual into clinical trials, level 1 evidence is scarce. We report prospective data of elderly patients with breast cancer treated by medical oncologists in Germany. Methods The SENORA project within the prospective cohort study TMK (Tumour Registry Breast Cancer) was conducted in 82 centres from 2007–2015. Among 2316 patients, half were enrolled with curative and half with palliative treatment intention. Overall, 478 patients (21%) were aged ≥ 70. Results In the adjuvant setting, elderly patients aged ≥ 70 had more advanced tumour stages at diagnosis and a higher prevalence of comorbidities than younger patients. Elderly patients received adjuvant chemotherapy less frequently, yet the 3-year disease-free survival was similar (86% vs. 88%). In the palliative setting, elderly patients more frequently received endocrine therapy and less frequently chemotherapy. Their median overall survival [24.9 months, 95% CI (confidence interval) 20.0–30.2] was significantly shorter than that of younger patients (39.7 months, 95% CI 34.9–44.2). A Cox proportional hazards model showed a significantly increased risk of mortality for: age ≥ 70 at start of therapy, negative HR- or HER2-status, higher number of metastatic sites, more comorbidities and high tumour grading at diagnosis. Conclusions Our results shed light on the routine treatment of elderly patients with breast cancer. A regression model demonstrated that age is but one of various prognostic factors determining the shorter overall survival of elderly patients.

Abstract
BACKGROUND In women with hormone receptor positive breast cancer, adjuvant endocrine therapy (AET) is associated with a significant survival advantage. Nonadherence is a particular challenge in older women, even though they stand to benefit the most from AET. Therefore, a novel eHealth tool (OPTIMUM) that integrates real-time analysis of health administrative claims data was developed to provide point-of-care decision support for clinicians. OBJECTIVES The objectives of the study are to determine the effectiveness of a patient-specific, real-time eHealth alert delivered at point-of-care in reducing rates of AET discontinuation and to understand patient-level factors related to AET discontinuation as well as to assess integration of eHealth alerts regarding deviations from best practices in administration of AET by cancer care teams. METHODS A prospective, 2-group controlled comparison pilot study will be conducted at 2 urban, McGill University-affiliated hospitals, the Royal Victoria Hospital and St. Mary's Hospital. A minimum of 43 patients per study arm will be enrolled through site-level allocation. Follow-up is 1.5 years. Health care professionals at the intervention site will have access to the eHealth tool, which will report to them in real-time medical events with known associations to AET discontinuation, an AET adherence monitor, and a discontinuation alert. Cox proportional hazard ratios with 95% confidence intervals will estimate risks of AET discontinuation. Tests for significance will be 2-sided with a significance level of P<.05. RESULTS This protocol has been approved and funded by the Canadian Institutes of Health Research. The study will evaluate site-level differences between AET discontinuation and AET adherence and assess care team actions at the intervention site. Participant enrollment into this project is expected to start September 2016 with primary data ready to present by June 2018. CONCLUSION This study will offer an opportunity to verify the feasibility of integrating an eHealth tool that aims to improve the long-term management of breast cancer in a high-risk population by allowing more timely intervention to prevent or rapidly address AET discontinuation.

Abstract
Breast cancer in the elderly is an increasing clinical problem. In addition, ~60% of deaths from breast cancer occur in women aged 65 years and older. Despite this, older women with breast cancer have been underrepresented in clinical trials, and this has led to less than optimal evidence to guide their therapy. The management of elderly women with early breast cancer is a complex process that requires careful evaluation of life expectancy, comorbidities, patient values, and risks and benefits of available treatment options. This review will focus on current adjuvant systemic therapy options for older women with breast cancer, discuss the principles in the decision-making process, and define the role of endocrine therapy, chemotherapy, and targeted agents.

CURRENT HEALTH SCIENCES JOURNAL 2016; 42:269-282.

Abstract
In this histopathological study we looked at 303 cases of breast carcinomas, managed though conservative breast surgery and later analysed with the help of a classical histopathological technique, paraffin embedding. The carcinomas were assessed in terms of tumor size, lymph node status, histological type, correlation between invasive tumors and an situ carcinoma component, resection margins, grading and patients age. Following assessment, we looked at associations between above morphological and clinical parameters and ipsilateral local recurrences. We concluded that more than half of our cases were carcinomas, measuring between 2 cm and 5 cm, with no associated lymph node involvement, in keeping with pTNM criteria for stage II. By far, in our study, the most frequent histopathological type was type NOS (63.37%) followed by invasive lobular carcinoma (10.56%) and mixed ducto-lobular invasive carcinoma (6.27%). Other types of invasive carcinoma were rarer, each representing less than 4% of cases. In regards to in situ carcinomas we noted the most common histological types to be both cribriform intraductal carcinoma and comedocarcinoma, each identified in 1.65% of cases. Amongst invasive breast carcinomas, infiltrating ductal carcinoma not otherwise specified (NOS) was found to be most commonly associated with in situ ductal carcinoma lesions. This was seen in 34.9% of cases, and was the only type associated with an extensive in situ component. Analysing the grading of mammary carcinomas in our study showed that the vast majority of cases (63.04%) were grade 3 tumors. In regards to surgical resection margins, ¾ of cases were noted to have negative margins. Tumor recurrences were noted in 12 cases. These cases were most commonly noted to reoccur following initial poorly differentiated, infiltrating ductal carcinomas, not otherwise specified (NOS), with positive resection margins, measuring less than 2 cm. Patiens tended to be under the age of 40 and had positive lymph nodes. The emergence of local recurrences after conservative surgery for early breast cancer is singnificantly linked to poorly differentiated primary tumors (p <0.05) but not correlated with histological type, presence of extensive intraductal carcinoma component, size of primary breast tumor or lymph node status ( p> 0.05). In terms of increasing the risk of ipsilateral recurrence the most important aspect highlighted in our sudy was the status of the resection margins. Patients with positive resection margins had a significantly high risk to develop recurrences after the conservative surgery, compared to those with negative margins (p <0.001).

Abstract
Studies to confirm the effect of acknowledged prognostic markers in older breast cancer patients are scarce. The aim of this study was to evaluate the prognostic value of HER-2 overexpression and PIK3CA mutations in older breast cancer patients. Female breast cancer patients aged 65 years or older, diagnosed between 1997 and 2004 in a geographical region in The Netherlands, with an invasive, non-metastatic tumour and tumour material available, were included in the study. The primary endpoint was relapse-free period and secondary endpoint was relative survival. Determinants were immunochemical HER-2 scores (0/1+, 2+ or 3+) and PIK3CA as a binary measure. Overall, 1698 patients were included, and 103 had a HER-2 score of 3+. HER-2 overexpression was associated with a higher recurrence risk (5 years recurrence risk 34 % vs. 12 %, adjusted p = 0.005), and a worse relative survival (10 years relative survival 48 % vs. 84 % for HER-2 negative; p = 0.004). PIK3CA mutations had no significant prognostic effect. We showed, in older breast cancer patients, that HER-2 overexpression was significantly associated with a worse outcome, but PIK3CA mutations had no prognostic effect. These results imply that older patients with HER-2 overexpressing breast cancer might benefit from additional targeted anti-HER-2 therapy.

Abstract
INTRODUCTION It was recently proposed that the molecular breast tumor subtypes are differently distributed in the elderly breast cancer patients, and also lack prognostic value. Given the limited number of elderly patients in previous studies, the aim of this study was to determine the prognostic effect of the molecular intrinsic subtypes in a large older breast cancer population. MATERIAL AND METHOD Older breast cancer patients with invasive, non-metastatic breast cancer with tumor material available for immunohistochemical determination of Ki67, EGFR, CK5/6 and HER-2 were included. ER and PR expression was retrieved from the pathology report. Molecular subtypes were: Luminal A, Luminal B, ERBB2, Basal-like and Unclassified. Primary endpoint was Relapse Free Period (RFP), taking into account the competing risk of mortality, and adjusted for the most important patient, tumor and treatment characteristics. Secondary endpoint was Relative Survival (RS). RESULTS Overall, 1362 patients were included. Patients with a Luminal A subtype had the lowest risk of recurrence (11% at 5 yrs). Patients with a Basal (24% at 5yrs) or ERBB2 (34% at 5yrs) molecular breast tumor subtype had the highest risk of recurrence. The ERBB2 subtype had the worst prognosis in terms of RFP (SHR 2.07, 95% CI 1.35-3.20; p = 0.001). The worst RS was again observed for the ERBB2 subtype (48% at 10 yrs). In multivariable analyses, the relative excess risk of death for all molecular subtypes was significantly worse compared to the Luminal A subtype. CONCLUSION Molecular intrinsic breast tumor subtypes have significant prognostic value in the elderly population, even after taking competing mortality into account.

Abstract
Breast cancer is the mostly commonly diagnosed cancer in women both in the United States and worldwide. Although advanced age at diagnosis is associated with more favorable tumor biology, mortality rates are comparatively higher in older adults, possibly attributed to advanced stage at presentation. There are minimal specific treatment-based guidelines in elderly patients with cancer, mostly attributable to their limited inclusion on clinical trials. In addition to the existing evidence from clinical trials and retrospective studies, practitioners need to take into consideration functional status, social support, patient preference, presence of comorbidities, and life expectancy when selecting optimal treatment.

Abstract
Breast cancer generally develops in older women and its incidence is continuing to increase with increasing age of the population. The pathology and biology of breast cancer seem to be different in the elderly, often resulting in the undertreatment of elderly patients and thus in higher rates of recurrence and mortal-ity. The aim of this review is to describe the differences in the biology and treatment of early breast cancer in the elderly as well as the use of geriatric assessment methods that aid decision-making. Provided there are no contraindications, the cornerstone of treatment should be surgery, as the safety and efficacy of surgical resection in elderly women have been well documented. Because most breast cancers in the elderly are hormone responsive, hormonal therapy remains the mainstay of systemic treatment in the adjuvant setting. The role of chemotherapy is limited to patients who test negative for hormone receptors and demonstrate an aggressive tumor profile. Although the prognosis of breast cancer patients has generally improved during the last few decades, there is still a demand for evidence-based optimization of therapeutic interventions in older patients.

Abstract
The objective was to determine whether histological types of breast cancer in elderly women influence clinical outcome. Four major databases were searched. All relevant articles, from January 1990 to December 2013, were screened. After applying inclusion and exclusion criteria, 11 studies were included. Invasive ductal carcinoma was the commonest (68.5-87.1%) histological type, followed by lobular carcinoma (6.9-17.7%). Four studies reported on survival. However, none specifically looked at survival according to different histological types. There are very little data on the influence of histological type on clinical outcome in primary breast cancer in elderly patients. Further studies may elucidate any potential influence and its relationship with tumor biology.

Abstract
As the overall population ages, the proportion of elderly patients (aged ≥65 years) with breast cancer also increases. Studies have shown that elderly patients with hormone receptor–positive breast cancer can derive as much benefit from treatment as do younger patients, yet they remain underrepresented in clinical trials and are often undertreated in clinical practice. Treatment decisions for older patients should not be based solely on chronologic age; a patient’s physiologic functioning and comorbidities must also be taken into consideration. For recurrent or metastatic disease, systemic treatment with endocrine therapies or chemotherapy may prolong a patient’s life and alleviate troublesome symptoms. Resistance to therapy remains a problem in the advanced breast cancer setting, with most patients eventually becoming resistant to additional treatment. New combination regimens that target multiple pathways, such as everolimus plus exemestane, have shown efficacy in elderly patients previously resistant to endocrine therapies, and future research may need to focus on such combinations in order to improve outcomes in this patient group. A number of investigational agents are in clinical development, although few studies identify their effects in the elderly patient population. Optimizing effective yet tolerable therapeutic regimens for elderly patients could improve their outcomes while ensuring that the goals of improved survival and quality of life are considered.

Abstract
Background Several randomized trials and meta-analyses confirmed a wide benefit of radiotherapy (RT), both after breast conserving surgery (BCS) and mastectomy. However, many elderly women don't receive RT. Hypofractionated (HF) RT allows « simplified » and more accessible treatments with equivalent results to classic RT in three large randomized trials. However, there are few available data on HF-RT for nodal irradiation, as well as for the boost. Methods We evaluated patients treated for IBC by HF-RT between 2004 and 2012 in two regional cancer centres. We used an original scheme delivering 45 Gy in 15 fractions three times a week, both after BCS or mastectomy, with or without nodal irradiation. After BCS, a 9 Gy boost in 3 fractions was delivered. Local, regional and distant recurrences were assessed, as well as acute and late cutaneous, cardiac or pulmonary toxicities. Results 205 patients were analysed, 116 after BCS (57 %) and 89 after mastectomy (43 %). Median age was 81 years (range: 52-91); 44 % had axillary nodal involvement (pN+). The Nottingham Prognostic Index (NPI) scored 0, 1, 2 and 3 in 10 %, 27 %, 44 % and 19 % of the cases. A nodal HF-RT was delivered in 65 patients (32 %) and boost in 98 patients (84 % of BCS) by 9 Gy/3 fr scheme. Fifty (24 %) patients underwent chemotherapy and 156 (75 %) hormonal treatment. With a 49-month median follow-up, 3/116 (2.6 %) patients and 4/89 (4.5 %) had local recurrence (LR) after BCS and mastectomy, respectively. The overall 5-year LR rate was 4.4 %. In univariate and multivariate analysis, LR risk factors were: high NPI (HR 5.46; p = 0.028), and triple negative tumour (HR 9.78; p = 0.006). Only 8 (4.5 %) patients had grade III skin toxicity; 29 (14 %) late fibrosis and 16 (8 %) telangiectasia. No pulmonary or cardiac toxicity was observed. Conclusion Our HF-RT scheme (with or without nodal irradiation) confirms in elderly patients the data from randomized trials, both after BCS or mastectomy. Toxicity seems very acceptable but requires a longer follow-up. A larger evaluation is still ongoing in several other centres in France.

Abstract
BACKGROUND Although breast cancer (BC) is one of the most common malignant diseases in women, the majority of the studies describing the characteristics of BC in elderly patients have been limited to survival assessments or tumor features, without using younger BC patients as a reference group. The aim of our study was to describe and compare tumor characteristics and management patterns in elderly versus younger breast cancer patients in Turkey. MATERIALS AND METHODS We retrospectively analyzed 152 patients with invasive breast cancer who underwent surgery in our institution between 2002 and 2012. Patients were divided into 2 groups according to age at the time of diagnosis. RESULTS There were 62 patients in the elderly group (≥65 years) and 90 patients in the younger group (<65 years). Compared to the younger group, tumors in the elderly group were more likely to be larger (p=0.018), of lower grade (p=0.005), and hormone receptor-positive (p>0.001). There were no significant differences regarding histology, localization, lymph node involvement, or types of surgical procedures between the 2 groups. Comorbidities were more common in elderly patients (p<0.001). In addition, elderly patients were more likely to receive hormonal therapy (p<0.001) and less likely to receive radiotherapy (p=0.08) and chemotherapy (p=0.003). There was no difference in survival and locoregional recurrence rates between the groups. CONCLUSIONS The results of this study demonstrate that breast cancer in elderly patients has more favorable tumor features, warranting less aggressive treatment regimens after surgery.

Abstract
There is very little information about breast cancer characteristics, treatment choices, and survival among elderly patients. The purpose of this multicenter retrospective study was to examine the clinical, pathologic, and biologic characteristics of 620 breast cancer patients age 70 years or older. Between June 1991 and May 2012, 620 patients with breast cancer, recruited from 16 institutions, were enrolled in the retrospective study. Patients had smaller tumors at diagnosis; only 15% of patients had tumors larger than 5 cm. The number of patients who had no axillary lymph node involvement was 203 (32.7%). Ninety-three patients (15.0%) had metastatic disease at diagnosis. Patients were characterized by a higher fraction of pure lobular carcinomas (75.3%). The tumors of the elderly patients were also more frequently estrogen receptor (ER) positive (75.2%) and progesterone receptor (PR) positive (67.3%). The local and systemic therapies for breast cancer differed according to age. An association between age and overall survival has not been demonstrated in elderly patients with breast cancer. In conclusion, the biologic behavior of older patients with breast cancer differs from younger patients, and older patients receive different treatments.

Abstract
BACKGROUND Although healthy women aged 65 years have a life expectancy of 20 years, there is a paucity of data on the performance of digital screening mammography among these women. The authors examined the performance and outcomes of digital screening mammography among a national group of women aged ≥65 years. METHODS From Breast Cancer Surveillance Consortium data for the years 2005 to 2011, the authors included 296,496 full-field digital screening mammograms among 133,042 women ages ≥65 years without a history of breast cancer. Sensitivity, specificity, positive predictive value (PPV1 ), recall rates, and 95% confidence intervals (95% CIs) were calculated across the spectrum of age and breast density. Multivariate logistic regression was used to compare mammography accuracy, cancer-detection rates (CDRs), and tumor characteristics by age and breast density. RESULTS Multivariate analyses revealed a significant decrease in the recall rate with age (P for linear trend [Ptrend ] < .001) and significant increases in specificity, PPV1 , and CDR with age (Ptrend < .001, Ptrend < .001, and Ptrend = .01, respectively). Sensitivity did not vary significantly with age. Among women with cancer, the proportion with invasive disease increased with age from 76% at ages 65 to 74 years to 81% at ages ≥80 years. There was a higher proportion of late stage cancers and positive lymph nodes among women ages 65 to 74 years compared with women in the older age groups. CONCLUSIONS The specificity, PPV1 , recall rate, and CDR of digital screening mammography improved with increased age. In addition, as age increased, the proportion of women with invasive versus ductal carcinoma in situ rose, whereas the proportion of women with positive lymph nodes decreased.

Abstract
Nearly half of all women diagnosed with breast or ovarian cancer are age 65 years or older with the number of women diagnosed expected to increase as the population ages and life expectancy improves. Older women are less likely to be offered standard cancer treatments, are more likely to develop higher toxicity, and have higher mortality. Chronologic age should not be the only factor used for making treatment decisions. Functional dependence, organ function, comorbidity, polypharmacy, social support, cognitive and/or psychosocial factors, overall life expectancy, and patient's goals of care are equally vital and should be assessed before and during treatment. In this review, current evidence and treatment guidelines for older women with breast or ovarian cancer are outlined.

Abstract
A considerable number of breast cancer diagnoses are made in older women. Differing physiological needs of older patients and biology of tumors compared with younger patients may alter treatment options between surgery and nonsurgical primary approaches. Adjuvant therapies may benefit these patients; however, concerns about toxicity and physical demands of treatment may affect patient choice regarding treatment. Furthermore, quality of life may be more important to the older individual than curative treatment alone. Growing evidence is emerging for employing Comprehensive Geriatric Assessment to determine other factors that may contribute to treatment decision-making in the older population. The way geriatric oncology is delivered varies, bringing the importance of the multidisciplinary team to the forefront of care delivery in this age group. Future research in this area should include combined consideration of tumor biology and geriatric needs.

A study of ductal versus non-ductal invasive breast carcinomas in older women: long-term clinical outcome and comparison with their younger counterparts. Breast Cancer Res Treat 2014; 147:671-4.

Abstract
Ductal carcinoma is the commonest histological type found in invasive breast carcinomas and may be associated with worse prognosis, when compared to non-ductal carcinoma. Older patients tend to display more favourable tumour biology than younger patients. This study aimed to investigate the significance of histological type and its relationship with clinical outcome in the older group. A total of 808 older (≥70 years) women with early operable primary breast cancer underwent surgery as their primary treatment, followed by optimal adjuvant therapies, in the Nottingham Breast Unit between 1973 and 2009. The histological types of the surgical specimens were reviewed and compared with those in a previously characterised younger (<70 years) series (N = 1,733), in terms of distribution and correlation with clinical outcome. Ductal type was associated with a significantly worse clinical outcome when compared to non-ductal type in the older group in terms of 10-year rates of metastasis-free survival (75 vs 79 %, p = 0.028) and overall survival (44 vs 52 %; p = 0.015). Similar worse clinical outcome was found with the ductal type in the younger group in terms of 10-year rates of metastasis-free survival (65 vs 79 %; p = 0.001) and overall survival (60 vs 78 %; p = 0.001). For all patients with ductal type carcinomas, the older series showed significantly better 10-year metastasis-free survival (75 vs 65 %, p < 0.001) and breast cancer-specific survival (75 vs 69 %, p = 0.025) when compared to the younger series. In both old and the young, ductal cancers were associated with poor survival outcome when compared to non-ductal cancers. When compared to their younger counterparts, older patients with ductal type carcinomas had better metastasis-free and breast cancer-specific survival rates (their lower overall survival was likely to be due to death from other causes), despite having a lower likelihood of receiving adjuvant systemic therapy.

Abstract
Primary tamoxifen therapy has been widely used to treat elderly women with ER-positive breast cancer in the past. Aromatase inhibitors may be more beneficial than tamoxifen when used as primary endocrine therapy in elderly patients. We aimed to retrospectively evaluate a series of elderly women with ER-positive breast cancer treated with primary letrozole therapy as sole therapy with a minimum of 5 years follow up. To identify possible predictive biomarkers a pilot immunohistochemical analysis was performed to assess the expression of PR, HER2, EGFR, BCL2 and p53. A total of 45 women, aged more than 70 years with a diagnosis of ER-positive breast cancer that was treated with primary letrozole therapy were identified. A case note review was undertaken to obtain clinical information. Formalin fixed paraffin embedded tumour tissue from diagnostic core biopsies was available for all patients. Immunohistochemical analysis was performed to establish the protein expression status of p53, PR, HER2, EGFR and BCL2. The mean age of the 45 patients was 87 years (range 70-101). Clinical benefit was seen in 60% of the patients. Median progression free survival was 53 months (95% CI - 34-72) and the median time to progression was 43 months (95% CI - 22-64). BCL2 was expressed in 45/45 (100%); PR in 38/45 (84%); EGFR in 13/45 (28%); HER2 in 9/45 (20%) and p53 in 5/45 (11%) of tissue samples. Positive expression of p53 was associated with poor progression free survival (p = 0.03) in this pilot study. This study demonstrates that letrozole as sole treatment appears to be a suitable treatment option for elderly patients with ER-positive breast cancer who are not fit for, or decline, surgery. The analysis of p53 in a larger study is warranted in order to assess its role as a biomarker in this patient group.

Association between oestrogens receptor expressions in breast cancer and comorbidities: a cross-sectional, population-based study. PLoS One 2014; 9:e98127. [PMID: 24848085 PMCID: PMC4029934 DOI: 10.1371/journal.pone.0098127] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2014] [Accepted: 04/28/2014] [Indexed: 12/25/2022] Open
Abstract
Background Breast cancer with oestrogen receptor expression is common in older women. Several factors, such as age and reproductive hormone exposure, have been associated with oestrogen receptor expression in breast cancer. However, the association between comorbidities and the oestrogen receptor expression has been poorly studied. We hypothesized that there was an association between burden comorbidity and breast cancer with oestrogen receptor expression in older women. Objective To determine whether oestrogen receptor expression in breast cancer was associated with burden comorbidity in community-dwelling women. Methods A total of 1,707 women with breast cancer registered on the list of a breast cancer registry were included. The recorded data included: age, Charlson Comorbidity Index score≥1, breast cancer characteristics (coded according to the International Classification of Diseases for Oncology), and breast cancer pathological stage (the pathological-tumour-node-metastasis, Scarff Bloom Richardson, and hormonal status of oestrogen receptor, progesterone receptor, and human epidermal growth factor receptor). Results Breast cancer with oestrogen receptor expression was identified in 1,378 patients (80·7%). The fully-adjusted logistic regression showed that oestrogen receptor expression was associated with Charlson Comorbidity Index score≥1 (odds ratio [OR] = 1·91,95%confidence interval [CI] = [1.01–3.61], P = 0·048), progesterone receptor expression (OR = 16·64, 95%CI = [11.62–23.81], P<0·001), human epidermal growth factor receptor (OR = 0·54, 95%CI = [0.34–0.84], P = 0·007), age (OR = 1.02, 95%CI = [1.00–1.03], P = 0.008), Scarff Bloom Richardson grade II and grade III (OR = 0·21with 95%CI = [0.10–0.44] and OR = 0·06 with 95%CI = [0.03–0.12], P<0·001). Conclusion Our findings provide new data showing an independent positive association between burden comorbidity and breast cancer with oestrogen receptor expression. This result confirms that evaluation of oestrogen receptor expression in breast cancer should not be limited to hormonal factors stratified by age.

Abstract
PURPOSE To compare the distribution and prognostic effect of the breast cancer molecular subtypes in young and elderly breast cancer patients. PATIENTS AND METHODS Our study population (n = 822) consisted of all early breast cancer patients primarily treated with surgery in our center between 1985 and 1996. A total of 142/822 fresh frozen tissues were available with good quality RNA and analyzed by gene expression microarray. Gene expression molecular subtypes were determined by correlation to the expression centroids of 534 "intrinsic" genes. Sections of a tissue micro array containing formalin-fixed paraffin-embedded tumor tissue of 714/822 patients were immunohistochemically (IHC) stained for Ki67, EGFR, CK5/6. Tumor expression of ER, PR, HER2 was previously determined. IHC molecular subtypes were defined based on expression of these markers: Luminal A: ER+ and/or PR+, HER2- and Ki67-; Luminal B: ER+ and/or PR+ and ki67+; ERBB2: ER-, PR- and HER2+; Basal-like: ER-, PR-, HER2- and EGFR+ and/or CK5/6+; Unclassified: ER-, PR-, HER2-, EGFR- and CK5/6-. IHC molecular subtypes were validated against gene expression defined molecular subtypes. Assessment of distribution and prognostic effect of molecular subtypes was stratified to age (<65 versus ≥65 years). RESULTS Validation of molecular subtypes determined by IHC against gene expression revealed a substantial agreement in classification (Cohen's kappa coefficient 0.75). A statistically significant association (p = 0.02) was found between molecular subtypes and age, where Luminal tumors were more often found in elderly patients, while ERBB2, basal-like and unclassified subtypes were more often found in young patients. Molecular subtypes showed a prognostic association with outcome in young patients concerning relapse-free period (RFP) (p = 0.01) and relative survival (RS) (p < 0.001). No statistically significant prognostic effect was found for molecular subtypes in elderly patients (RFP p = 0.5; RS p = 0.1). Additional analyses showed that no molecular subtypes showed a statistically significant difference in outcome for elderly compare to young patients. CONCLUSION We have shown that molecular subtypes have a different distribution and prognostic effect in elderly compared to young breast cancer patients, emphasizing the fact that biomarkers may have different distributions and prognostic effects and therefore different implications in elderly compared to their younger counterparts. Our results support the premise that breast cancer clinical behavior is significantly affected by patient age. We suggest that competing risks of death in elderly patients, ER-driven differences and micro-environmental changes in biology are underlying these age-dependent variations in patient prognosis.

Abstract
In clinical practice, approximately 50% of new cases of breast cancer occur in women over the age of 65 years, although very few elderly women have been enrolled in the numerous randomized trials conducted so far. Notwithstanding less aggressive biologic features compared with younger patients, breast cancer impacts on mortality of elderly women, especially if not adequately treated. As confirmed by meta-analyses, hormonal therapy is the most effective adjuvant measure for patients with localized disease, whereas the decrease in the benefit of cytotoxic treatment with increased risk of toxicity make the decision on when and how to administer it a major challenge for the medical oncologist. Careful evaluation of biological prognostic factors, performance status and geriatric parameters, such as functional independence, comorbidities and cognitive function of the patient, along with determination of her life expectancy and preferences, represent the relevant information on which the oncologist should ground their decision for integrated treatment with conservative surgery, radiotherapy and hormonochemotherapy in otherwise healthy women, or attenuated or palliative measures for the frail patients, in order to maximize the balance of benefits and toxicities. The aims of this review are to summarize the most relevant concepts for decision making in the clinical practice and discuss the results of recent research concerning the additional needs of elderly women with early breast cancer.

Abstract
Breast cancer is the most common cancer in women and its incidence increases with age. Older women are not often offered optimal treatment compared with younger women for any particular stage. This is due to various reasons, including the lack of evidence for older women from well-conducted clinical trials. In this paper, the currently available evidences from clinical trials are reviewed and the various treatment options for older women with early breast cancer are discussed.

Abstract
OBJECTIVE AND METHODS We retrospectively analyzed clinicopathologic features and survival in breast cancer patients who had T1 or T2 primary tumours and 1-3 histologically involved axillary lymph nodes and who were treated with modified radical mastectomy without adjuvant radiotherapy (rt). We also explored prognosis to find the high- and low-risk groups. RESULTS From May 2001 to April 2005, 368 patients treated at Tianjin Tumor Hospital met the study criteria. The 5- and 8-year rates were 7.2% and 10.7% for locoregional recurrence (lrr), 85.1% and 77.7% for disease-free survival (dfs), and 92.8% and 89.3% for overall survival (os). Multivariate Cox regression analysis showed that age, tumour size, estrogen receptor (er) status, and lymphovascular invasion (lvi) were independent prognostic factors for lrr and dfs. Based on 4 patient-related factors that indicate poor prognosis (age < 40 years, tumour > 3 cm, er negativity, and lvi), the high-risk group (patients with 3 or 4 factors, accounting for 12.5% of the cohort) had 5- and 8-year rates of 24.3% and 36.9% for lrr, 57.2% and 39.2% for dfs, and 74.8% and 43.8% for os compared with 5.0% and 7.1% for lrr, 88.9% and 83.1% for dfs, 91.6% and 83.4% for os in the low-risk group (patients with 0-2 factors, accounting for 87.5% of the cohort; p < 0.001). CONCLUSIONS Our study identified several risk factors that correlated independently with a greater incidence of lrr and distant metastasis in patients with T1 and T2 breast cancer and 1-3 positive nodes. Patients with 0-2 risk factors may not be likely to benefit from post-mastectomy rt, but patients with 3-4 risk factors may need rt to optimize locoregional control and improve survival.

Abstract
Older women are not being given the opportunity to benefit from the improvements in both local and systemic treatment for breast cancer. Mammographic screening call/recall system ceases at age 72, making access more difficult. Knowledge about breast cancer in those aged >75 is significantly reduced in terms of understanding symptoms and personal risk but studies have shown that intervention can improve this, at least in the short term. Although older women are more likely to have estrogen receptor positive tumours, nevertheless, more than one-third of women aged over 70 have grade III, aggressive breast cancers. Whenever possible, older women should be offered breast conserving therapy rather than mastectomy since this not only improves their quality of life but also reduces risk of subsequent mental health problems. Endocrine treatment alone should not be used other than in patients with severe co-morbidity and a life-expectancy of less than a year. As adjuvant treatment in those with estrogen receptor positive cancers, the choice between tamoxifen and an aromatase inhibitor will depend upon co-morbidity, side-effects and patient choice.

Abstract
Background: As age advances breast cancer appears to change its biological characteristics, however, very limited data are available to define the precise differences between older and younger patients. Methods: Over 36 years (1973–2009), 1758 older (⩾70 years) women with early operable primary breast cancer were managed in a dedicated clinic. In all, 813 underwent primary surgery and 575 good quality tumour samples were available for biological analysis. The pattern of biomarkers was analysed using indirect immunohistochemistry on tissue microarrays. Comparison was made with a previously characterised series of younger (<70 years) patients. Results: There was high expression of oestrogen receptor (ER), PgR, Bcl2, Muc1, BRCA1 and 2, E-cadherin, luminal cytokeratins, HER3, HER4, MDM2 and 4 and low expression of human epidermal growth factor receptor (HER)-2, Ki67, p53, EGFR and CK17. Oestrogen receptor and axillary stage appeared as independent prognostic factors. Unsupervised partitional clustering showed six biological clusters in older patients, five of which were common in the younger patients, whereas the low ER luminal cluster was distinct in the older series. The luminal phenotype showed better breast cancer-specific survival, whereas basal and HER2-overexpressing tumours were associated with poor outcome. Conclusion: Early operable primary breast cancer in older women appears as a distinct biological entity, with existence of a novel cluster. Overall older women showed less aggressive tumour biology and ER appeared as an independent prognostic factor alongside the time-dependent axillary stage. These biological characteristics may explain the differences in clinical outcome and should be considered in making therapeutic decisions.

Prognostic value of bcl-2 expression among women with breast cancer in Libya. Tumour Biol 2013; 34:1569-78.

Abstract
We studied the association of the immunohistochemical bcl-2 expression in Libyan breast cancer with clinicopathological variables and patient outcome. Histological samples from 170 previously untreated primary Libyan breast carcinoma patients were examined. In immunohistochemistry, the NCL-L-bcl-2-486 monoclonal antibody was used. Positive expression of bcl-2 was found in 106 patients (62.4 %). The bcl-2 expression was significantly associated with estrogen receptor (p<0.0001) and progesterone receptor positive tumors (p=0.002), small tumor size (p<0.0001), low tumor grade (p<0.0001), negative axillary lymph nodes (p<0.0001), early stages (p=0.001), and low risk of metastasis (p<0.0001). Positive expression was also associated with older patients (>50 years; p=0.04). Histological subtypes and family history of breast cancer did not have significant relationship with bcl-2. Patients with positive expression of bcl-2 had lower recurrence rate than bcl-2-negative patients and better survival after median follow-up of 47 months. Patients with high bcl-2 staining were associated with the best survival. The role of bcl-2 as an independent predictor of disease-specific survival was assessed in a multivariate survival (Cox) analysis, including age, hormonal status, recurrence, histological grade, and clinical stage variables. Bcl-2 (p<0.0001) and clinical stage (p=0.016) were independent predicators of disease-specific survival. For analysis of disease-free survival, the same variables were entered to the model and only bcl-2 proved to be an independent predictor (p=0.002). Patients with positive expression of bcl-2 were associated with low grade of malignancy, with lower recurrence rate, with lower rate of death, and with longer survival time. Bcl-2 is an independent predictor of breast cancer outcome, and it provides useful prognostic information in Libyan breast cancer. Thus, it could be used with classical clinicopathological factors to improve patient selection for therapy.

Abstract
BACKGROUND The number of elderly patients with breast cancer is increasing, and a large proportion of these older patients do not receive conventional treatment. Clinical and biological characteristics of tumours at this age and survival according to local or systemic therapy were analysed. MATERIAL AND METHOD A total of 96 consecutive early breast cancer patients over 80 years of age diagnosed in our Unit between January 2002 and September 2008 were retrospectively investigated. Of them, 54 underwent surgery with or without adjuvant hormonal treatment, and 42 received primary hormonal therapy. RESULTS Tumours of patients 80 years old or older had more favourable biological characteristics, including expression of steroid receptors, and absence of c-erb B2 expression. Overall survival was 50 months for the group subjected to surgery, and 44 months for the group who did not undergo surgery. The survival free of local recurrence in the surgery group was 44 months, whereas it was 18 months in the non-surgery group. CONCLUSION In a cohort of patients aged 80 years and older, survival was similar in those who received hormonal or surgical therapy, although the former had a shorter period of progression-free survival or local recurrence.

Abstract
ESR1 is one of the most important transcription factors and therapeutic targets in breast cancer. By applying systems-level re-analysis of publicly available gene expression data, we uncovered a potential regulator of ESR1. We demonstrated that orphan nuclear receptor NR2E3 regulates ESR1 via direct binding to the ESR1 promoter with concomitant recruitment of PIAS3 to the promoter in breast cancer cells, and is essential for physiological cellular activity of ESR1 in estrogen receptor (ER)-positive breast cancer cells. Moreover, expression of NR2E3 was significantly associated with recurrence-free survival and a favourable response to tamoxifen treatment in women with ER-positive breast cancer. Our results provide mechanistic insights on the regulation of ESR1 by NR2E3 and the clinical relevance of NR2E3 in breast cancer.

Abstract
Populations around the world are aging, and the associated increase in cancer incidence has led to the recognition of the importance of geriatric oncology. Chronological age is a poor determinant of pharmacological response to cancer chemotherapy agents. Age-associated changes in physiology and organ function have a significant impact on the clinical pharmacology of cancer chemotherapy agents used in cancer treatment. Altered response to medicines in older people is a consequence of changes in body composition, organ function, concomitant pathophysiology, multiple medications, genetic determinants of drug response, and patient's clinical status. These issues highlight the need to individualize the management of cancer in the older people with consideration of age-related changes in the clinical pharmacology of cancer drugs, analgesics, and adjunctive therapies.

Abstract
This article describes the range of cancer patients in longterm care and provides a framework for clinical decision making. The benefits and burdens of providing standard therapy to a vulnerable population are discussed. To give more specific guidelines for advocates of treatment, skeptics, and others, the authors present best estimates of the current burden of cancer in the long-term care population and current screening guidelines that apply to the elderly under long-term care. Experience-based suggestions are offered for oncologists and clinicians involved in long-term care to help them respond to patient and family concerns about limitations of cancer care.
