Abstract
PURPOSE The efficacy of adjuvant chemotherapy in elderly breast cancer patients is currently controversial. This study aims to provide personalized adjuvant chemotherapy recommendations using deep learning (DL). METHODS Six models with various causal inference approaches were trained to make individualized chemotherapy recommendations. Patients who received actual treatment recommended by DL models were compared with those who did not. Inverse probability treatment weighting (IPTW) was used to reduce bias. Linear regression, IPTW-adjusted risk difference (RD), and SurvSHAP(t) were used to interpret the best model. RESULTS A total of 5352 elderly breast cancer patients were included. The median (interquartile range) follow-up time was 52 (30-80) months. Among all models, the balanced individual treatment effect for survival data (BITES) performed best. Treatment according to following BITES recommendations was associated with survival benefit, with a multivariate hazard ratio (HR) of 0.78 (95% confidence interval (CI): 0.64-0.94), IPTW-adjusted HR of 0.74 (95% CI: 0.59-0.93), RD of 12.40% (95% CI: 8.01-16.90%), IPTW-adjusted RD of 11.50% (95% CI: 7.16-15.80%), difference in restricted mean survival time (dRMST) of 12.44 (95% CI: 8.28-16.60) months, IPTW-adjusted dRMST of 7.81 (95% CI: 2.93-11.93) months, and p value of the IPTW-adjusted Log-rank test of 0.033. By interpreting BITES, the debiased impact of patient characteristics on adjuvant chemotherapy was quantified, which mainly included breast cancer subtype, tumor size, number of positive lymph nodes, TNM stages, histological grades, and surgical type. CONCLUSION Our results emphasize the potential of DL models in guiding adjuvant chemotherapy decisions for elderly breast cancer patients.

Abstract
Primary dose reduction (PDR) in the first course of chemotherapy is an empirical practice, commonly used in older population. Patients over 70 years old receiving a first course of chemotherapy for a solid tumor were enrolled. A total of 179 patients were included. Standard dose was used in 69.8% of patients, while 30.2% received PDR of chemotherapy. Only 29.6% received a standardized geriatric assessment. Patients receiving standard doses presented 83.2% of toxicities, while 68% of toxicities were reported in patients receiving PDR. The toxicity rate was significantly decreased in patients treated with reduced first-cycle dose of chemotherapy.

Treatment and survival of patients diagnosed with high-risk HR+/HER2- breast cancer in the Netherlands: a population-based retrospective cohort study. ESMO Open 2024; 9:103008. [PMID: 38677006 PMCID: PMC11067336 DOI: 10.1016/j.esmoop.2024.103008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 02/21/2024] [Accepted: 03/03/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND Several factors may increase the risk of recurrence of patients diagnosed with hormone receptor-positive human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer (BC). We aim to determine the proportion of patients with high-risk HR+/HER2- BC within the total HR+/HER2- BC cohort and compare their systemic treatments and survival rates with those of patients with low- and intermediate-risk HR+/HER2- BC and triple-negative (TN) BC. PATIENTS AND METHODS Women diagnosed with nonmetastatic invasive HR+/HER2- BC and TNBC in the Netherlands between 2011 and 2019 were identified from the Netherlands Cancer Registry. Patients with HR+/HER2- BC were categorised according to risk profile, defined by nodal status, tumour size, and histological grade. High-risk HR+/HER2- BC was defined by either four or more positive lymph nodes or one to three positive lymph nodes with a tumour size of ≥5 cm or a histological grade 3 tumour. Overall survival (OS) and relative survival (RS) were calculated using the Kaplan-Meier and Pohar-Perme method. RESULTS In this study of 87 455 patients with HR+/HER2- BC, 44 078 (50%) patients were diagnosed with low risk, 28 452 (33%) with intermediate risk, and 11 285 (13%) with high-risk HR+/HER2- BC. In 3640 (4%) patients, the risk profile could not be defined. Endocrine therapy and chemotherapy were used in 38% and 7% of low-risk, 90% and 47% of intermediate-risk, and 94% and 73% of high-risk patients, respectively. The 10-year OS and RS rates were 84.1% [95% confidence interval (95% CI) 83.5% to 84.7%] and 98.7% (95% CI 97.3% to 99.4%) in low-risk, 75.1% (95% CI 74.2% to 76.0%) and 91.7% (95% CI 89.7% to 93.3%) in intermediate-risk, and 63.4% (95% CI 62.0% to 64.7%) and 72.3% (70.1% to 74.3%) in high-risk patients. The 10-year OS and RS rates of 12 689 patients with TNBC were 69.7% (95% CI 68.6% to 70.8%) and 79.1% (95% CI 77.0% to 80.9%), respectively. CONCLUSION The poor prognosis of patients with high-risk HR+/HER2- BC highlights the need for a better acknowledgement of this subgroup and supports ongoing clinical trials aimed at optimising systemic therapy.

Adjuvant chemotherapy and survival outcomes in older women with HR+/HER2- breast cancer: a propensity score-matched retrospective cohort study using the SEER database. BMJ Open 2024; 14:e078782. [PMID: 38490656 PMCID: PMC10946384 DOI: 10.1136/bmjopen-2023-078782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 03/04/2024] [Indexed: 03/17/2024] Open
Abstract
OBJECTIVES This study aimed to investigate the impact of adjuvant chemotherapy (ACT) on survival outcomes in older women with hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer (BC). DESIGN A retrospective cohort study using data from the Surveillance, Epidemiology, and End Results database, which contains publicly available information from US cancer registries. SETTING AND PARTICIPANTS The study included 45 762 older patients with BC aged over 65 years diagnosed between 2010 and 2015. METHODS Patients were divided into two groups based on age: 65-79 years and ≥80 years. Propensity score matching (PSM) was employed to balance clinicopathological characteristics between patients who received ACT and those who did not. Data analysis used the χ2 test and Kaplan-Meier method, with a subgroup analysis conducted to identify potential beneficiaries of ACT. OUTCOME MEASURES Overall survival (OS) and cancer-specific survival (CSS). RESULTS Due to clinicopathological characteristic imbalances between patients with BC aged 65-79 years and those aged ≥80 years, PSM was used to categorise the population into two groups for analysis: the 65-79 years age group (n=38 128) and the ≥80 years age group (n=7634). Among patients aged 65-79 years, Kaplan-Meier analysis post-PSM indicated that ACT was effective in improving OS (p<0.05, HR=0.80, 95% CI 0.73 to 0.88), particularly in those with advanced disease stages, but did not show a significant benefit in CSS (p=0.09, HR=1.13, 95% CI 0.98 to 1.31). Conversely, for patients aged ≥80 years, ACT did not demonstrate any improvement in OS (p=0.79, HR=1.04, 95% CI 0.79 to 1.36) or CSS (p=0.09, HR=1.46, 95% CI 0.69 to 2.26) after matching. Subgroup analysis also revealed no positive impact on OS and CSS. CONCLUSIONS Patients with HR+/HER2- BC ≥80 years of age may be considered exempt from ACT because no benefits were found in terms of OS and CSS.

The Impact of Being Underweight on the Prognosis of Older Patients With Early Breast Cancer. CANCER DIAGNOSIS & PROGNOSIS 2023; 3:678-686. [PMID: 37927809 PMCID: PMC10619563 DOI: 10.21873/cdp.10272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 10/12/2023] [Indexed: 11/07/2023]
Abstract
Background/Aim The number of older patients with breast cancer has been increasing and a major challenge is to develop optimal treatment strategies for these patients, who often have comorbidities. Obesity is reportedly a poor prognostic factor in breast cancer, however there is limited research on underweight patients. Clarifying the relationship between physique and prognosis may contribute to the establishment of optimal treatment strategies for older patients with breast cancer. Patients and Methods This retrospective study examined clinicopathological data from a multicenter collaborative database on 1,076 patients aged 70 years or older who had undergone curative surgery. According to the body mass index (BMI), patient physique was defined as underweight (<18.5 kg/m2), normal (18.5-24.9 kg/m2) or obese (≥25 kg/m2). In this study, we explored the relationship between the physique of patients with breast cancer and outcomes. Results Underweight patients had a significantly lower rate of chemotherapy administration (p=0.017) and a higher rate of presence of other cancer (p=0.022). During the observation period (median of 75.2 months), 133 patients (12%) developed recurrent disease and 131 patients (12%) died. Age, BMI, tumor size, progesterone receptor and the presence of other cancer were independent factors relating to overall survival (p<0.001, p=0.027, p=0.002, p=0.008 and p=0.005, respectively). Patients with a low BMI had a significantly shorter overall survival, but there was no association with disease-free survival in this subset of patients. Conclusion Overall survival was shorter in underweight older patients with breast cancer. Our data indicate that being underweight should be considered both in treatment decisions and in future studies of outcomes for older patients with breast cancer.

Abstract
AIM OF THE STUDY Evaluation of the impact of a de-escaleted chemotherapy regimen consisting of capecitabine (Cap) on invasive disease-free survival (iDFS) in patients ≥65 years with node-positive/high-risk node-negative early breast cancer (BC) receiving ibandronate (Ib). METHODS ICE (Ib with or without Cap in Elderly patients with early breast cancer) was a multicentre phase 3 clinical trial with a 2020 update of long-term follow-up for overall survival enroling node-positive/high-risk node-negative patients ≥65 years with early BC. Patients were randomised to Cap 2000 mg/m² day 1-14 q3w for 6 cycles plus Ib (50 mg p.o. daily or alternatively 6 mg intravenous q4w) or Ib alone for 2 years. Endocrine therapy was recommended for hormone receptor (HR)-positive patients. The primary endpoint was iDFS analysed using Cox proportional hazards regression and log-rank analysis. RESULTS 1358 (96.4%) of 1409 randomised patients started treatment. 564 (83.4%) completed 6 cycles of Cap. 513 (77.7%) and 516 (78.8%) completed Ib in the Cap+Ib and Ib alone arm, respectively. Median age was 71 (range 64-88) years, 1099 (81%) were HR-positive, 705 (51.9%) node-negative. At a median follow-up of 61.3 months, 5-year iDFS was 78.8% for Cap+Ib versus 75.0% for Ib alone (p = 0.80). Effects were independent of age, nodal, and HR status. The addition of Cap caused significantly higher skin and gastrointestinal toxicity. CONCLUSIONS The adjuvant combination of Cap+Ib did not show significantly better iDFS than Ib alone in node-positive/high-risk node-negative older BC patients, of whom HR-positive patients were also treated with endocrine therapy.

Abstract
BACKGROUND The lymph node (LN) status is a crucial prognostic factor for breast cancer (BC) patients. Our study aimed to compare the predictive capabilities of three different LN staging systems in node-positive BC patients and develop nomograms to predict overall survival (OS). METHODS We enrolled 71,213 eligible patients from the SEER database, and 667 cases from our hospital were used for external validation. All patients were divided into two groups based on the number of removed lymph nodes (RLNs). The prognostic abilities of pN stage, positive LN ratio (LNR), and log odds of positive LN (LODDS) were compared using the C-indexes and AUC values. LASSO regression was performed to identify significant factors associated with prognosis and develop corresponding nomogram models. RESULTS Our study found that LNR had superior predictive performance compared to pN and LODDS among patients with RLNs < 10, while pN performed better in patients with RLNs ≥ 10. In the training set, the nomogram models exhibited excellent clinical applicability, as evidenced by the C-indexes, ROC curves, calibration plots, and decision curve analysis curves. Moreover, the nomogram classification accurately differentiated risk subgroups and improved discrimination. These results were externally validated in the validation cohort. CONCLUSION Physicians should select different LN staging systems based on the number of RLNs. Our novel nomograms demonstrated excellent performance in both internal and external validations, which may assist in patient counseling and guide treatment decision-making.

Abstract
BACKGROUND In early luminal breast cancer, the Oncotype DX® Recurrence Score (RS) prognostic and predictive value with regards to chemotherapy (CHT) application benefit has been broadly validated. In older patients its value has not been deeply addressed. This study aimed to evaluate the benefits of RS testing and to look at differences in treatment allocation for these patients when compared with younger ones. METHODS We included data from consecutive patients with early luminal HER2-negative breast cancer, treated between 2010 and 2022 at the University Hospital Basel and Cantonal Hospital Baselland, Switzerland. The older cohort included 63 (19%) patients aged ≥70, and the younger cohort 263 (81%) patients aged <70. RESULTS Older breast cancer patients had more co-morbidities (N = 36, 57% vs. N = 92, 35%, p = 0.002) and a higher clinical risk status (N = 49, 78% vs. N = 155, 59%; p = 0.01) when compared to younger patients. Histopathologic characteristics were significantly different between the two cohorts. Although older patients had a higher clinical risk status (78% vs. 59%) (p = 0.01), most of them (74%) received no CHT. Specifically, adjuvant CHT was administered less frequently in older than in younger patients (13% vs. 22%; p = 0.01). Moreover, older patients were less likely to complete CHT (>4 cycles: 78% vs. 97%). CONCLUSION Breast cancer patients aged ≥70 have higher clinical risk status, more co-morbidities, higher clinical stage (driven by larger tumor size), and more often RS ≥26. However, they receive fewer adjuvant RT and CHT than those aged <70. RS maintains its independent prognostic value in older patients. However, assessing the predictive value of additional CHT benefit remains challenging due to significant differences in CHT administration. Although therapy decision-making in older patients with breast cancer still follows RS-based guidelines, clinical practice indicates an individualized treatment approach.

Abstract
Anoop TMObjectives The lack of data on management of elderly breast cancer patients' population makes most oncologists reluctant to treat them with the standard treatment protocols as advised for the younger patients. This study was done to identify the survival outcome and predictors of survival in elderly breast cancer patients treated with curative intent. Materials and Methods Newly diagnosed patients with breast cancer aged more than 65 years who received treatment with curative intent were included. Disease-free survival (DFS) and overall survival were estimated using the Kaplan-Meier method. Survival curves were compared using log-rank test. Cox regression analysis was done to find out the predictors of DFS. Results This study included 112 elderly breast cancer patients. In our patient population, 79 (70.5%) were less than or equal to 70 years of age and 33 (29.5%) were more than or equal to 70 years. Median age was 68 years. Charlson comorbidity index score was six and above in 31 (28.1) patients. Median DFS in our study was 46 months. Median DFS was not reached in patients less than or equal to 70 years of age, whereas it was 50 months (47-53) among patients more than or equal to 70 years of age, p -value-0.009. In univariate analysis, age more than or equal to 70 years and locally advanced breast cancer were the predictors of DFS with hazard ratio (HR) of 2.8 (1.2-6.69), p -value 0.013 and 2.9 (1.12-7.6), and 0.027, respectively. In multivariate analysis, age more than or equal to 70 years was the only significant predictors of DFS with HR of 2.8 (1.2-6.5) and p -value of 0.015. Conclusion Standard curative intent treatment was well tolerable among elderly patents. Elderly age more than 70 years was a unique predictor of DFS. We need to incorporate tools to assess life expectancy and functional status that will help us predict toxicity of treatment and survival advantage more precisely.

Abstract
BACKGROUND No randomized controlled trials have compared implant and flap reconstruction. Recently, worse longitudinal outcomes have been suggested for flap reconstruction. The authors compared long-term oncologic outcomes of postmastectomy breast reconstruction using propensity score matching. METHODS A retrospective study of postmastectomy reconstruction was achieved using the Weill Cornell Breast Cancer Registry between 1998 and 2019. Patients were matched using propensity scores based on demographic, clinical, and surgical characteristics. Kaplan-Meier estimates, Cox-regression models, and restricted mean survival times (RMST) were used to evaluate patient outcomes. RESULTS Before matching, 1395 implant and 586 flap patients were analyzed. No difference in overall survival and recurrence were observed. Multivariable models showed decreased survival for Medicare/Medicaid [hazard ratio (HR), 3.09; 95% CI, 1.63 to 5.87; P < 0.001], pathologic stage II (HR, 2.98; 95% CI, 1.12 to 7.90; P = 0.028), stage III (HR, 4.88; 95% CI, 1.54 to 15.5; P = 0.007), 11 to 20 lymph nodes positive (HR, 3.66; 95% CI, 1.31 to 10.2; P = 0.013), more than 20 lymph nodes positive (HR, 6.41; 95% CI, 1.49 to 27.6; P = 0.013). RMST at 10 years after flap reconstruction showed 2 months of decreased survival time compared with implants (9.56 versus 9.74 years; 95% CI, -0.339 to -0.024; P = 0.024). After matching, 563 implant and 563 flap patients were compared. Reconstruction was not associated with overall survival and recurrence. RMST between implant and flap reconstruction showed no difference in each 5-year interval over 20 years. CONCLUSION Postmastectomy breast reconstruction was not associated with a difference in long-term oncologic outcomes over a 20-year period. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
Introduction Cancer is a condition where abnormal cells proliferate uncontrollably, leading to metastasis, which can be related to death. Breast cancer is the most prevalent type among women worldwide. Early detection with screening mammography has contributed to the decline in breast cancer incidence and mortality. Breast cancer patients are more likely to develop cardiovascular disease, with elderly patients dying from complications. Understanding the patients' cardiovascular status prior to treatment is essential. The study's objective was to evaluate the cardiovascular characteristics of women with breast cancer at diagnosis within the designated time frame of one year. Methodology This was a retrospective study that focused on patients in Taif City, Saudi Arabia, who were initially diagnosed with primary breast cancer over a span of one year. The inclusion criteria encompassed eligible patients, while those not meeting the criteria were excluded. Data extraction from patients' records was conducted, and the analysis was executed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States). Results This study analyzed the cardiovascular attributes of breast cancer patients, focusing on 136 female cases. The study found significant patterns concerning cardiovascular risk factors in breast cancer patients, categorized by menopausal status. Premenopausal female cases had a mean age of 43.09 ± 8.31 years, while postmenopausal patients had an average age of 58.07 ± 11.70 years. Postmenopausal patients had a higher prevalence of overweight/obesity, irregular menstrual cycles, type II diabetes, hypertension, and hyperlipidemia compared to their premenopausal counterparts. No significant differences were found between the two groups regarding low-density lipoprotein (LDL) cholesterol levels, axillary lymph node metastasis, or distant metastasis. This study emphasized the importance of regular check-ups for menopausal women to detect potential health complications early. Conclusion In summary, breast cancer is a global health concern, and understanding its impact on the cardiovascular system is crucial for comprehensive patient care. A study in Saudi Arabia found associations between cardiovascular risk factors and menopausal status in breast cancer patients. Postmenopausal patients had more prevalent risk factors, emphasizing the need for proactive assessment and management. Age-appropriate screenings and interventions are essential. Integrated healthcare approaches should consider the interplay between breast cancer and cardiovascular health, with medical professionals vigilant in evaluating and addressing risk factors to mitigate complications and optimize long-term outcomes.

Adjuvant therapeutic strategy decision support for an elderly population with localized breast cancer: A monocentric cohort retrospective study. PLoS One 2023; 18:e0290566. [PMID: 37616325 PMCID: PMC10449163 DOI: 10.1371/journal.pone.0290566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 08/09/2023] [Indexed: 08/26/2023] Open
Abstract
Guidelines for the management of elderly patients with early breast cancer are scarce. Additional adjuvant systemic treatment to surgery for early breast cancer in elderly populations is challenged by increasing comorbidities with age. In non-metastatic settings, treatment decisions are often made under considerable uncertainty; this commonly leads to undertreatment and, consequently, poorer outcomes. This study aimed to develop a decision support tool that can help to identify candidate adjuvant post-surgery treatment schemes for elderly breast cancer patients based on tumor and patient characteristics. Our approach was to generate predictions of patient outcomes for different courses of action; these predictions can, in turn, be used to inform clinical decisions for new patients. We used a cohort of elderly patients (≥ 70 years) who underwent surgery with curative intent for early breast cancer to train the models. We tested seven classification algorithms using 5-fold cross-validation, with 80% of the data being randomly selected for training and the remaining 20% for testing. We assessed model performance using accuracy, precision, recall, F1-score, and AUC score. We used an autoencoder to perform dimensionality reduction prior to classification. We observed consistently better performance using logistic regression and linear discriminant analysis models when compared to the other models we tested. Classification performance generally improved when an autoencoder was used, except for when we predicted the need for adjuvant treatment. We obtained overall best results using a logistic regression model without autoencoding to predict the need for adjuvant treatment (F1-score = 0.869).

Identifying Patterns and Barriers in OncotypeDX Recurrence Score Testing in Older Patients With Early-Stage, Estrogen Receptor-Positive Breast Cancer: Implications for Guidance and Reimbursement. JCO Oncol Pract 2023; 19:560-570. [PMID: 37192427 DOI: 10.1200/op.22.00731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 02/16/2023] [Accepted: 03/13/2023] [Indexed: 05/18/2023] Open
Abstract
PURPOSE To evaluate the clinical patterns of utilization of OncotypeDX Recurrence Score (RS) in early-stage, hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer (BC) at an academic center with previously established internal reflex testing guidelines. METHODS RS testing in accordance with preexisting reflex criteria and predictors of utilization outside of reflex criteria were retrospectively analyzed for the years 2019-2021 in a quality improvement evaluation. Patients were grouped according to OncotypeDX testing within (cohort A) or outside (cohort B) of predefined criteria which included a cap at age older than 65 years. RESULTS Of 1,687 patients whose tumors had RS testing, 1,087 were in cohort A and 600 in cohort B. In cohort B, nearly half of patients were older than 65 years (n = 279; IQR, 67-72 years). For patients older than 65 years, those with RS testing were younger (median age: 69 v 73 years), with higher grade cancers (G2-3: 84.9% v 54.7%) and were more likely to be treated with chemotherapy (15.4% v 4.1%). Issues for implementation of RS testing in older patients were identified, including potential structural barriers related to the current policy on the reimbursements of genomic tests. CONCLUSION Internal guidelines may facilitate standardized utilization of the RS in early-BC. Our data suggest that clinicians preferred broader utilization of RS across the age spectrum, with therapeutically important consequences. Modifying the current policy for reimbursement of RS testing and in internal reflexive testing criteria for those older than 65 years is warranted.

Abstract
Background Elderly patients with breast cancer are highly heterogeneous, and tumor load and comorbidities affect patient prognosis. Prediction models can help clinicians to implement tailored treatment plans for elderly patients with breast cancer. This study aimed to establish a prediction model for breast cancer, including comorbidities and tumor characteristics, in elderly patients with breast cancer. Methods All patients were ≥65 years old and admitted to the Peking Union Medical College Hospital. The clinical and pathological characteristics, recurrence, and death were observed. Overall survival (OS) was analyzed using the Kaplan-Meier curve and a prediction model was constructed using Cox proportional hazards model regression. The discriminative ability and calibration of the nomograms for predicting OS were tested using concordance (C)-statistics and calibration plots. Clinical utility was demonstrated using decision curve analysis (DCA). Results Based on 2,231 patients, the 5- and 10-year OS was 91.3% and 78.4%, respectively. We constructed an OS prediction nomogram for elderly patients with early breast cancer (PEEBC). The C-index for OS in PEEBC in the training and validation cohorts was 0.798 and 0.793, respectively. Calibration of the nomogram revealed a good predictive capability, as indicated by the calibration plot. DCA demonstrated that our model is clinically useful. Conclusion The nomogram accurately predicted the 3-year, 5-year, and 10-year OS in elderly patients with early breast cancer.

Abstract
BackgroundWith the aging of the population, the number of elderly breast cancer cases has increased. However, there is a lack of effective randomized clinical trial data to support whether elderly patients should receive chemotherapy. Our goal was to observe the relationship between chemotherapy and breast cancer-specific survival (BCSS) in elderly breast cancer patients and to identify those who could benefit from chemotherapy.MethodsWe collected the data of patients who were diagnosed with invasive ductal carcinoma and older than 70 years in the SEER database from 1995 to 2016. The independent predictors of BCSS were identified by Cox regression analysis. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were performed to eliminate confounding factors.ResultsA total of 142,537 patients were collected, including 21,782 patients in the chemotherapy group and 120,755 patients in the non-chemotherapy group. We identified the same potential predictors of BCSS after PSM and IPTW, such as age, race, grade, stage, therapy, subtype. A nomogram for predicting 3-year, 5-year and 10-year BCSS was constructed. The 3-year, 5-year and 10-year AUCs of the nomogram were 0.842, 0.819, and 0.788. According to the risk stratification of model predictive scores, patients in the high-risk group achieved the greatest improvement in BCSS after receiving chemotherapy.ConclusionsOur study suggests that women older than 70 years with larger tumors, higher grade, positive nodes, negative hormone receptor and inactive local therapy gain prognostic benefits from chemotherapy, but for those with low- and median-risk, conventional chemotherapy should be administered cautiously.

Abstract
BACKGROUND Additional systemic treatment for early breast cancer in elderly is challenged by increasing comorbidities with age. We aimed to examine the effect of additional chemotherapy on overall survival in patients aged 70 years or older and the impact of comorbidities on chemotherapy benefit. METHODS This retrospective monocentric cohort study includes data from all patients aged 70 years and older who underwent surgery for an early breast cancer from 1997 to 2016. A propensity score analysis allowed adjustment for chemotherapy prescription preferences based on tumour characteristics. RESULTS Of 15,599 patients who had surgery for an early breast cancer, 1743 (11.2%) over 70 years old were included, of whom 269 (15.4%) had received additional chemotherapy. Median follow-up was 5.3 years. Multivariate analyses on the propensity-score weighted cohort (n = 1 354) identified improved overall survival in patients with chemotherapy versus without (HR 0.54, 95% CI 0.31-0.92). Chronic obstructive pulmonary disease (HR, 2.16, 95% CI 1.40-3.34) and polypharmacy (HR 1.40, 95%CI 1.07-1.84) were associated with worse overall survival. No statistically significant interactions were identified between these comorbidities and chemotherapy prescription. CONCLUSION Additional chemotherapy in elderly with early breast cancer is feasible and associated with overall survival benefit, supporting the importance of chemotherapy considerations in this population, and of avoiding undertreatment based on chronological age considerations alone.

Abstract
BACKGROUND Curative intent cancer treatment needs to be balanced with patient comorbidities and quality of life when treating older women with breast cancer. We examined consultation patterns and association of age at diagnosis with lack of specialist cancer consultations for older women with breast cancer. METHODS We conducted a population-based retrospective cohort study of older women (≥ 70 years of age) with incident, non-metastatic breast cancer (2010-2018) by linking administrative databases in Ontario, Canada. The outcomes of interest were lack of specialist cancer consultation (surgeon, medical oncology, or radiation oncology) within 12 months of diagnosis. Association of age with lack of specialist cancer consultation was examined using Poisson regression modeling. RESULTS Of 21,849 older women, 2.4% (n = 517) did not have any specialist cancer consultation within 12 months of diagnosis; lack of any specialist cancer consultation increased with age (0.8% for age 70-74 years, 1.3% for age 75-79 years, 2.5% for age 80-84 years, and 7.0% for age ≥ 85 years; p < 0.001). The proportion of patients who did not have consultations with surgeons, medical oncologists, and radiation oncologists was 8.6% (n = 1888), 34.4% (n = 7510), and 24.7% (n = 5404), respectively. Older age group was independently associated with an increased likelihood of lacking any specialist consultation, as well as not receiving surgical and medical oncology consultations. CONCLUSION More than one-third of women ≥ 70 years of age with non-metastatic breast cancer did not have a consultation with a medical oncologist, with women aged ≥ 85 years least likely to have a medical oncology consultation.

PURPOSE Older women with high-risk early breast cancer (EBC) benefit from adjuvant chemotherapy, but their treatment is frequently complicated by toxic side effects, resulting in dose reductions and delays. This makes it challenging for oncologists to maintain a relative dose intensity (RDI) ≥ 85%, as recommended for optimal curative-intent treatment. Understanding which women are at risk of receiving suboptimal RDI may inform treatment discussions and guide early, targeted supportive care or geriatric comanagement interventions. METHODS This was a prespecified secondary analysis of the HOPE trial, which enrolled women age ≥ 65 years with EBC initiating neoadjuvant or adjuvant chemotherapy. RDI was calculated as the ratio of delivered to planned chemotherapy dose intensity. The primary outcome was low RDI, defined as RDI < 85%. Multivariable logistic regression with stepwise selection was used to evaluate the association between baseline variables (demographic, clinical, and geriatric assessment) and low RDI. Survival probability was estimated using the Kaplan-Meier method, and the log-rank test was used to compare overall survival. RESULTS Three hundred twenty-two patients (median age at diagnosis, 70 years; range, 65-86 years) were included. The median follow-up was 4 years. Sixty-six patients (21%) had a low RDI. Age ≥ 76 years (odds ratio [OR], 2.57; 95% CI, 1.12 to 5.91; P = .03), lower performance status (OR, 4.32; 95% CI, 1.98 to 9.42; P < .001), and use of anthracycline-based or cyclophosphamide, methotrexate, and fluorouracil regimens (OR, 3.47; 95% CI, 1.71 to 7.05; P < .001) were associated with low RDI. The 5-year overall survival probability was 0.80 versus 0.91 in patients with RDI < 85 versus ≥ 85%, respectively (log-rank P = .02). CONCLUSION One in five older patients with EBC treated with standard chemotherapy received low RDI and had inferior survival outcomes. Older patients at risk for low RDI should be identified and targeted upfront before initiating chemotherapy.

Abstract
BACKGROUND Currently, the proportion of standard chemotherapy for elderly patients is much lower than that for young patients, with little evidence from clinical trials supporting the use of chemotherapy for elderly patients. The effectiveness of chemotherapy for the elderly suffering from breast cancer remains to be further verified. METHODS A total of 75,525 female breast cancer patients aged 70 years or older were hereby identified, all from the Surveillance, Epidemiology, and End Results (SEER) database from January 1, 2010 to December 31, 2016. Kaplan-Meier analysis and multivariable Cox proportional model were performed to evaluate the effectiveness of chemotherapy on overall survival (OS) and breast cancer-specific survival (BCSS). Propensity score matching (PSM) (PSM ratio: 1:1, caliper: 0.2 standard deviation of propensity score) was applied to construct balanced cohorts with or without chemotherapy based on demographic and pathophysiological characteristics. RESULTS A total of 33,177 eligible patients were included, with 5273 (15.89%) receiving chemotherapy. Through PSM, 8360 patients were successfully matched, and balances between groups were almost reached. In the matched data set, multivariable Cox analysis reveals that chemotherapy was associated with a 36% and 21% risk reduction on OS (HR = 0.64, 95% CI 0.58 to 0.71) and BCSS (HR = 0.79, 95% CI 0.69 to 0.91), respectively. Furthermore, subgroups with more adjacent lymph nodes involved by tumor, or nonluminal A, were inclined to benefit more from chemotherapy. Moreover, chemotherapy did not increase the chances of dying from heart disease. CONCLUSIONS The present study provided evidence that chemotherapy may improve the prognosis of elderly breast cancer, especially for those subpopulations that benefit more from chemotherapy treatment.

Abstract
Breast cancer is the most common cancer diagnosed among women worldwide and more than half are diagnosed above the age of 60 years. Life expectancy is increasing and the number of breast cancer cases diagnosed among older women are expected to increase. Undertreatment, mostly due to unjustifiable fears of advanced-age and associated comorbidities, is commonly practiced in this group of patients who are under-represented in clinical trials and their management is not properly addressed in clinical practice guidelines. With modern surgery and anesthesia, breast surgeries are considered safe and is usually associated with very low complication rates, regardless of extent of surgery. However, oncoplastic surgery and management of the axilla can be tailored based on patients’- and disease-related factors. Most of chemotherapeutic agents, along with targeted therapy and anti-Human epidermal growth factor receptor-2 (HER2) drugs can be safely given for older patients, however, dose adjustment and close monitoring of potential adverse events might be needed. The recently introduced cyclin-D kinase (CDK) 4/6-inhibitors in combination with aromatase inhibitors (AI) or fulvestrant, which changed the landscape of breast cancer therapy, are both safe and effective in older patients and had substituted more aggressive and potentially toxic interventions. Despite its proven efficacy, adjusting or even omitting adjuvant radiation therapy, at least in low-risk older patients, is safe and frequently practiced. In this paper, we review existing data related to breast cancer management among older patients across the continuum; from resection of the primary tumor through adjuvant chemotherapy, radiation and endocrine therapy up to the management of recurrent and advanced-stage disease.

Abstract
Although patients over 65 years of age represent the majority of breast cancer patients, we have limited data on the safety and efficacy of medical oncology treatments in this population. Their indications are based primarily on expert agreement. This literature review discusses the known data on the safety and efficacy of the main medical treatments for breast cancer: chemotherapy, cytokine-dependent kinase inhibitors 4/6, agents targeting human epidermal growth factor receptor-2, novel antibody conjugates, and immunotherapy.

Abstract
BACKGROUND The benefit of chemotherapy for older patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer (EBC) is a key area of debate. Gene expression profiling (GEP) may identify patients deriving benefit, but their predictive role has not been established for older adults. We summarise evidence on efficacy, safety, and quality-of-life impacts of chemotherapy and on GEP use and impact in older HR-positive, HER2-negative EBC patients. METHODS We conducted a literature search of PubMed and Embase on publications describing prospective studies evaluating chemotherapy in older adults with HR-positive, HER2-negative EBC and on publications describing retrospective and prospective studies evaluating GEP in older adults. RESULTS Eight publications on chemotherapy use, including 2,035 older patients with EBC were selected. Only one trial evaluated chemotherapy survival benefits in older adults, showing no benefit. Of four studies comparing different regimens, only one showed the superiority of taxanes versus anthracyclines alone. Those investigating alternative regimens did not show improvements over standard regimens despite significant limitations. Five publications on GEP, including 445,323 older patients, were included and investigated Oncotype DX. Limited evidence shows that GEP aids treatment decisions in this population. GEP was offered less frequently to older versus younger patients. Higher Recurrence Score was prognostic for distant recurrence, but chemotherapy did not improve prognosis. CONCLUSIONS In older patients with HR-positive, HER2-negative, chemotherapy survival benefits EBC are unclear and GEP is less used. Although its prognostic role is well established, its predictive role remains unknown.

Abstract
Introduction Treatment advances in metastatic renal cell carcinoma (mRCC) have improved overall survival (OS) in mRCC patients over the last two decades. This single center retrospective analysis assesses if the purported survival benefits are also applicable in elderly mRCC patients. Methods 401 patients with mRCC treated at Hannover Medical School from 01/2003–05/2016 were identified and evaluated by chart review. Treatment periods were defined as 01.01.2003–31.12.2009 (P1) and 01.01.2010–31.05.2016 (P2). Age groups were defined according to WHO classes (≤ 60 years: younger, > 60–75 years: elderly and > 75 years: old). Descriptive statistics, Kaplan–Meier analysis and logistic regression were performed. Results Median OS improved from 35.1 months in P1 to 59.1 months in P2. Sub-division into the respective age groups revealed median survival of 38.1 (95%-CI: 28.6–47.6) months in younger patients, 42.9 (95%-CI: 29.5–56.3) months among elderly patients and 27.3 (95%-CI: 12.8–41.8) months among old patients. Risk reduction for death between periods was most evident among old patients (young: HR 0.71 (95%-CI: 0.45–1.13, p = 0.2); elderly: HR 0.62 (95%-CI: 0.40–0.97, p = 0.04); old: HR 0.43 (95%-CI: 0.18–1.05, p = 0.06)). Age ≥ 75 years was an independent risk factor for death in P1 but not in P2. Conclusion Improved OS in the targeted treatment period was confirmed. Surprisingly elderly and old patients seem to profit the most form expansion of therapeutic armamentarium, within the TKI-dominated observation period.

Abstract
BACKGROUND Older women are poorly represented in trials evaluating chemotherapy for breast cancer (BC). This study aimed to describe survival and associated factors among elderly women receiving chemotherapy for non-metastatic BC. METHODS This was a population-based cohort study including women ≥ 70 years old diagnosed with invasive, non-metastatic BC from 2010 to 2017 in SEER. Among those who received chemotherapy, overall survival (OS) was determined using Kaplan-Meier curves and hazard ratios were reported with 95% confidence intervals (CIs). Adjustment was made for available confounders. Co-morbidity is not available in SEER. BC-specific survival (BCSS) and subdistribution hazard ratios were determined using competing risks analysis. RESULTS The cohort consisted of 109,239 women aged 70+, of whom 17,961 (16%) received chemotherapy. Chemotherapy patients were younger (median 73.0 years vs. 77.0), had more advanced disease (25% stage III vs. 5.2%), and were more likely to receive mastectomy (50% vs. 33%). Among chemotherapy patients, 5-year OS was 77.8% (95% CI 76.9-78.6%), and for women 80+ was 60.2% (95% CI 57.5-63.1%). More recent diagnoses, no previous history of cancer, and receipt of radiotherapy were all associated with improved BCSS. Conversely, older age, higher tumour grade, advanced stage, and human epidermal growth factors receptor (HER)2 negative tumours were associated with worse BCSS. 56% of deaths were due to BC, and women aged 80+ had worse BCSS compared to those aged 70-79 (adjusted sdHR 1.62, 95% CI 1.43-1.84). CONCLUSIONS Elderly women with advanced disease can achieve good survival after chemotherapy for non-metastatic BC. Those with HER2+ disease have superior survival, reinforcing benefit in this population.

Abstract
Data regarding chemotherapy options and benefits in older women with early triple-negative breast cancer (TNBC) are limited. Our study aimed to assess the effects of adjuvant chemotherapy on recurrence-free survival (RFS), breast cancer-specific survival (BCSS), and overall survival (OS) rates in elderly TNBC patients. Patients aged ≥65 years diagnosed with stage I-III TNBC (except T1aN0) between 2010 and 2016 were retrospectively included. Multivariate Cox regression was performed to minimize bias. A total of 177 patients were included with a median age of 69 years (range, 65-86), almost all had a Charlson Comorbidity Index of 0-2, and 127 (71.8%) received chemotherapy. Patients who received chemotherapy were younger, had more advanced-stage disease and had better ECOG performance status (P<0.05). Among the 127 patients who were administered chemotherapy, 45 (35%) received taxane plus carboplatin, 36 (28%) received anthracycline-and-taxane-based regimens, and 23 (18%) received taxane-based regimens. The regimen options differed based on patient age and tumour stage (P<0.05). Nearly 80% of the patients completed ≥6 cycles of chemotherapy, and half had their dosage decreased. After adjustment for confounding factors, patients who received ≥6 cycles of chemotherapy were found to have improved RFS rates (hazard ratio [HR], 0.28; 95% confidence interval [CI], 0.09-0.87; P=0.027), and receipt of chemotherapy (≥1 cycle) was associated with better BCSS (HR, 0.19; 95% CI, 0.04-0.97; P=0.046) and OS (HR, 0.26; 95% CI, 0.08-0.87; P=0.029) rates. These results support the considering the risk for recurrence and performing individualized assessments when determining the appropriate chemotherapy approach for older women with early TNBC.

Abstract
Abstract
Japanese women have the highest life expectancy in the world and breast cancer is the most prevalent cancer among them. However, little data are available to support the evidence-based clinical management due to the fact that older adults are commonly excluded from most clinical trials. In Japan the rate of other cause of death in older patient was about a half, then we should consider whether or not breast cancer may affect the patient’s life expectancy to avoid either overtreatment or undertreatment. Although management principles in older patients may be similar with those of younger age, these differences would be caused by relatively short life expectancy, some comorbidity, drug interactions and low functional status. Then, their treatment needs to be individualized. To this end, employing a comprehensive geriatric assessment may be advantageous, which enables to evaluate patient vulnerability from several different aspects, to predict adverse events of chemotherapy and to identify geriatric problems in advance so that extra support and modified treatment can be provided. Before treatment we should assess the patient’s goals and values regarding the management of the cancer, especially on balancing survival benefit with immediate quality of life impairment due to anti-cancer therapy. In Japan Clinical Oncology Group (JCOG) , a randomized controlled trial for older patients with advanced stage HER2-positive breast cancer is ongoing as an inferiority design including geriatric assessment (JCOG1607, HARB TEA study). Best practice, current management and how to approach decision making in older patients with breast cancer are summarized.

[PMID: 35449473 DOI: 10.1007/s10549-022-06604-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 04/06/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE This study assessed chemotherapy use trends before (neoadjuvant chemotherapy [NAC]) or after surgery (adjuvant chemotherapy [AdC]) among older women with breast cancer and examined factors related to NAC receipt. METHODS Women (> 65 years) diagnosed with stage I-III breast cancer during 2010-2017 who received NAC or AdC were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. All patients were stratified into six strata based on subtype (hormone receptor-positive/human epidermal growth factor receptor 2-negative [HR + /HER2-], HER2 + , and triple-negative breast cancer [TNBC]) and stage (I-II and III). Cochran-Armitage tests were performed to test temporal trends of NAC use in each stratum. Multivariable logistic regression analyses were performed to identify factors (sociodemographic and clinical) related to NAC use. RESULTS Among included older (mean ± standard deviation: 72.3 ± 5.2 years) women (N = 8,495) with stage I-III breast cancer, NAC use increased from 11.7% (2010) to 32.6% (2017). Significant increases in NAC were found in all strata (p < .0001) with more substantial increases in HER2 + disease and TNBC compared to HR + /HER2- disease. Multivariable logistic regressions identified the youngest age category (66-69 years) and later stage as significant (p < 0.05) predictors of NAC receipt in most strata, in addition to diagnosis year. CONCLUSION Similar to the overall breast cancer population, NAC use increased among a population of older women. NAC was received by most patients with stage III HER2 + disease or TNBC in more recent years and was more common among younger elderly women and those in stage III.

Abstract
Oncotype DX (ODX) recurrence score (RS) is a validated tool to guide the use of adjuvant chemotherapy (AC) in hormone receptor+/HER2- breast cancer. In this analysis, we examine (1) characteristics associated with ODX testing and (2) the association between ODX RS and receipt of AC across age and nodal status. Women with HR+/HER2–, early-stage (T1-2, N0-1) breast cancers from 2010–2017 in the National Cancer Database were included. 530,125 met inclusion and 255,971 received ODX testing. Older women were less likely to receive testing; however, nodal positivity increased use of testing. High ODX RS was associated with increased mortality, though the association was not consistent across age and was most strongly associated with mortality among younger, node-negative women. Older women with high ODX RS, regardless of nodal status, were less likely to receive AC. Clinicians may be employing ODX RS to support treatment decisions against the receipt of AC.

Abstract
Background Breast cancer remains the most common cancer in women and a leading cause of death. Elderly people have a higher incidence of breast cancer since it increases with age. Furthermore, the extended life expectancy and advances in imaging techniques have led to an increased number of cases. Guidelines concerning the management of this specific age group are rare, mainly due to underrepresentation of seniors in clinical trials. Moreover, increased frailty, comorbidities, and a poor performance status make it complex to determine the best therapeutic approach. Summary In this review, we attempt to summarize the current literature and aim to provide specific approaches and recommendations for prompt diagnosis, treatment, and management of breast cancer in the elderly. Key Messages The establishment of applicable protocols is imperative and efforts are being made in this direction. A careful geriatric assessment and adequate consultation should be the standard of care and patient's preferences should always be considered.

Is adjuvant chemotherapy necessary in older patients with breast cancer? Breast Cancer 2022; 29:498-506.

Abstract
BACKGROUND Due to the lack of clinical trials on the efficacy of chemotherapy in older patients, an optimal treatment strategy has not been developed. We investigated whether adjuvant chemotherapy could improve the survival of older patients with breast cancer in Japan. METHODS We retrospectively analyzed data of patients with breast cancer aged ≥ 70 years who underwent breast cancer surgery in eight hospitals between 2008 and 2013. Clinical treatment and follow-up data were obtained from the patients' medical electric records. RESULTS A total of 1095 patients were enrolled, of which 905 were included in the initial non-matched analysis. The median age and follow-up period were 75 (range 70-93) and 6.3 years, respectively. Of these patients, 127 (14%) received adjuvant chemotherapy (Chemo group) while the remaining 778 (86%) did not (Control group). The Chemo group was younger (mean age in years 73 vs 76; P < 0.0001), had a larger pathological tumor size (mean mm 25.9 vs 19.9; P < 0.0001), and more metastatic axillary lymph nodes (mean numbers 2.7 vs 0.7; P < 0.0001) than the Control group. The disease-free survival (DFS) and overall survival (OS) did not differ significantly between the two groups (P = 0.783 and P = 0.558). After matched analyses, DFS was found to be significantly prolonged with adjuvant chemotherapy (P = 0.037); however, OS difference in the matched cohort was not statistically significant (P = 0.333). CONCLUSION The results showed that adjuvant chemotherapy was associated with a reduced risk of recurrence, but survival benefits were limited.

Abstract
Age is one of the most important risk factors for the development of breast cancer. Nearly a third of all breast cancer cases occur in older women (aged ≥70 years), with most cases being oestrogen receptor-positive (ER+). Such tumours are often indolent and unlikely to be the ultimate cause of death for older women, particularly when considering other comorbidities. This Review focuses on unique clinical considerations for screening, detection, and treatment regimens for older women who develop ER+ breast cancers-specifically, we focus on recent trends for de-implementation of screening, staging, surgery, and adjuvant therapies along the continuum of care. Additionally, we also review emerging basic and translational research that will further uncover the unique underlying biology of these tumours, which develop in the context of systemic age-related inflammation and changing hormone profiles. With prevailing trends of clinical de-implementation, new insights into mechanistic biology might provide an opportunity for precision medicine approaches to treat patients with well tolerated, low-toxicity agents to extend patients' lives with a higher quality of life, prevent tumour recurrences, and reduce cancer-related burdens.

Abstract
Over a third of breast cancers are diagnosed in patients ≥70 years. With the ageing of the population, the number of older breast cancer patients will continue to rise. Older patients are under-represented in clinical studies underpinning breast cancer therapy, and frequently do not receive guideline-concordant care. This review outlines the evidence on the efficacy and the safety of systemic treatment options for the management of early-stage breast cancer (EBC) in older adults and identifies where critical data gaps exist. Chemotherapy is beneficial for older patients with oestrogen receptor (ER)-negative EBC, whilst the benefit for those with ER-positive disease is less certain. Careful consideration should be given to the side-effect profile of the treatment regimen chosen, owing to the risks of myelosuppression and cardiac damage, as well as toxicities, such as neuropathy, that may impact independence. The impact of chemotherapy on quality of life (QOL) outcomes appears significant but reversible in this population. Gene expression profiling, benefit and chemotherapy toxicity prediction tools integrating global health considerations hold promise to better inform chemotherapy decisions in this population. Benefits on targeted anti-human epidermal growth factor receptor 2 (HER2) agents is maintained in older EBC patients with a favourable safety profile. Endocrine therapy including aromatase inhibitors is the standard of care in this population, and extended treatment decisions should consider effects on bone health and life expectancy. More trials recruiting older adults with pragmatic designs and meaningful endpoints for this population are warranted to better inform systemic treatment decisions and discussion with patients.

ANZ J Surg 2021; 91:2418-2424. [PMID: 34476882 DOI: 10.1111/ans.17175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 08/10/2021] [Accepted: 08/14/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND We aimed to identify compliance with systemic treatment recommendations in early breast cancer (EBC) patients managed by Australian BreastSurgANZ members. METHODS A retrospective analysis of patients diagnosed with EBC included in BreastSurgANZ prospective database from January 2002 to December 2016 was conducted. Data was available on patients with BC treated by over 350 surgeons across the six states and two territories of Australia. RESULTS Over the 15 year period, 102 660 EBC episodes were recorded in 99 800 patients. As a group, the five key performance indicators (KPIs) set by the BreastSurgANZ relating to systemic treatment were achieved. Overall, patients were compliant with systemic treatment recommendations with 89.1% of patients receiving treatment in accordance with recommendations from their treating surgeon. The highest rate of non-compliance with systemic treatment was for endocrine therapy (11.9%). Of the 2368 patients who did not proceed with the recommended endocrine treatment, 1284 (54%) patients did so because of patient refusal. Failure to receive chemotherapy was associated with older age (aOR 1.02; p < 0.001), patients living in regional areas (aOR 1.23; p = 0.001) and those with node negative disease (aOR 0.97; p = 0.003). CONCLUSIONS The majority of Australian patients with EBC are being recommended for adjuvant systemic therapy in accordance with BreastSurgANZ KPI's. Treatment compliance was very high. This finding emphasises the importance of prospective data collection and auditing of established KPIs by surgeons, in areas other than direct surgical outcomes. Further research into the reasons why patients refuse treatment is needed.

[PMID: 34384462 PMCID: PMC8359046 DOI: 10.1186/s13019-021-01608-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 08/02/2021] [Indexed: 11/13/2022] Open
Abstract
Objective We aimed to explore the cardiovascular characteristics of patients who were initially diagnosed with breast cancer. Methods A total of 600 patients who were diagnosed with primary breast cancer were included in this retrospective study. The data of fasting blood glucose, total cholesterol, total triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lipoprotein (a) (LP (a)) and serum uric acid were collected. Univariate analysis was used to evaluate the cardiovascular risk factors (CVRFs) in patients with breast cancer. The arteriosclerotic cardiovascular disease (ASCVD) risk assessment was performed. Multivariate analysis was used to identify the factors that influenced axillary lymph node metastasis (ALNM). Results Compared with the premenopausal group, the prevalence of overweight/obesity (47.6% vs. 35.2%), diabetes (12.8% vs. 4.3%) and hypertension (49.7% vs. 26.3%) were significantly increased in the postmenopausal group (p < 0.05). Comparisons of rural patients and urban patients showed that there were significant differences in the diagnostic age (49.94 ± 9.92 vs. 52.59 ± 11.13) in the rural patients was notably younger in comparison with the urban patients (p < 0.05). However, the number of menopausal patients (44.3% vs. 53.3%) in the rural group were decreased in comparison with the urban group (p < 0.05). In ASCVD risk stratification, the proportion of low-risk patients (56.4% vs. 90.8%), medium-risk patients (20.6% vs 0.3%) and high-risk patients (19.3% vs. 6.6%) were significantly different between the postmenopausal group and premenopausal group (p < 0.05). Residence (OR 0.735; 95% CI 0.516–1.046; p = 0.087), the number of children (OR 1.250; 95% CI 0.990–1.578; p = 0.061) and LP (a) of ≥ 500 mg/L (OR 0.603; 95% CI 0.342–1.063; p = 0.080) were independent influencing factors of ALNM. Conclusion Postmenopausal patients have more CVRFs and higher risks of ASCVD than premenopausal patients initially diagnosed with breast cancer. There was a correlation between CVRFs and ALNM in patients with breast cancer.

Systemic therapy and prognosis of older patients with stage II/III breast cancer: A large-scale analysis of the Japanese Breast Cancer Registry. Eur J Cancer 2021; 154:157-166. [PMID: 34293663 DOI: 10.1016/j.ejca.2021.06.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 06/03/2021] [Accepted: 06/08/2021] [Indexed: 12/31/2022]
Abstract
AIM This study aimed at investigating the real-world prognostic impact of systemic treatment in older patients with stage II/III breast cancer (BC). METHODS This retrospective cohort study included patients with stage II/III primary BC, aged ≥55 years, and registered in the Japanese Breast Cancer Registry from 2004 to 2011. The clinicopathological characteristics, treatments, and prognosis of patients aged ≥75 years (older) were compared to those of younger patients. RESULTS In total, 56,093 patients (12,727, ≥75 years; 17,860, 65-74 years; 25,506, 55-64 years) were enrolled. In the older group, 9.2% with a luminal (hormone receptor [HR]+/human epidermal growth factor receptor 2 [HER2]-), 32.9% with a triple-negative (TN, HR-/HER2-), and 27.4% with a HER2-positive (any-HR/HER2+) receptor were administered chemotherapy. In those with luminal cancer, the 5-year breast cancer-specific survival (BCSS) was approximately 95% in all age groups. Meanwhile, among those with TN and HER2-positive BC, the older group had a poorer BCSS. The 5-year overall survival (OS) was also poorer in the older group across all subtypes. Among older patients matched using clinicopathological factors, chemotherapy use was associated with improved OS in the luminal and HER2-positive subtypes. CONCLUSIONS Chemotherapy use was lower among older patients with stage II/III breast cancer. Those with TN and HER2-positive BC had a lower BCSS than their younger counterparts. Chemotherapy may be beneficial in improving the OS in older patients with luminal and HER2-positive BCs. Treatment for older patients should be individualized, based on tumor-related factors, quality of life, and the patient's health status.

Systemic therapy for early breast cancer in older adults: current status and prospects. Curr Opin Oncol 2021; 33:574-583. [PMID: 34183493 DOI: 10.1097/cco.0000000000000768] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
PURPOSE OF REVIEW In this review, we describe the evidence on the efficacy and the safety of systemic treatments for the management of early breast cancer (EBC) in older individuals. RECENT FINDINGS Chemotherapy has a temporary impact on quality of life (QoL) for older EBC patients and improves survival outcomes for those with oestrogen receptor (ER)-negative disease. Benefits were seen also in the context of comorbidities, although these may be influenced by selection bias. The Cancer and Aging Research Group-Breast Cancer tool can predict the risk of severe toxicities on chemotherapy in older patients. Gene expression profiling is less frequently used in older adults although it holds promise to better inform patient selection also in this age group.Postneoadjuvant systemic therapy and novel agents remain poorly described in older patients with EBC. No disease-free survival benefits were seen in older patients receiving abemaciclib plus adjuvant endocrine therapy. SUMMARY Chemotherapy is beneficial for selected older patients with high-risk, ER-negative EBC. Although its impact on QoL is temporary, preferences, higher risk of toxicity and competing risks need to be carefully considered. Open questions remain on novel therapeutic approaches and gene expression profile in older EBC patients and more real-world evidence is warranted.

Suboptimal therapy following breast conserving surgery in triple-negative and HER2-positive breast cancer patients. Breast Cancer Res Treat 2021; 189:509-520. [PMID: 34176085 DOI: 10.1007/s10549-021-06303-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Accepted: 06/13/2021] [Indexed: 01/03/2023]
Abstract
PURPOSE To assess potential disparities in guideline-concordant care delivery among women with early-stage triple-negative and HER2-positive breast cancer treated with breast conserving therapy. METHODS Women ≥ 40 years old diagnosed with pT2N0M0 triple-negative or HER2-positive breast cancer treated with primary surgery and axillary staging between 2012 and 2017 were identified using the National Cancer Database (NCDB). The primary outcome was receipt of adjuvant systemic therapy and radiation concordant with current guidelines. Multivariable log-binomial regression was used to assess the prevalence of optimal therapy use across patient and cancer characteristics. Kaplan-Meier curves were used to assess 5-year overall survival. Multivariable Cox proportional hazards regression was used to compare the impact of optimal therapy on 5-year mortality. RESULTS 11,785 women were included with 7,843 receiving optimal therapy. Receipt of optimal therapy decreased with age even after adjusting for comorbidities and cancer characteristics; other sociodemographic factors were not associated with differences in receipt of optimal therapy. Among patients who did not receive adjuvant systemic therapy, most were not offered the treatment (49%) or refused (40%). Overall 5-year survival was higher among women who received optimal therapy (89% [95% CI 88.0-89.3] vs. 66% [95% CI 62.9-68.5]). Patients who received suboptimal therapy were over twice as likely to die within 5 years of their diagnosis (adjusted HR 2.44, 95% CI 2.12-2.82). CONCLUSION Age is the primary determinant of the likelihood of a woman to receive optimal adjuvant therapies in high-risk early-stage breast cancer. Patients who did not receive optimal therapy had significantly diminished survival.

Updated recommendations regarding the management of older patients with breast cancer: a joint paper from the European Society of Breast Cancer Specialists (EUSOMA) and the International Society of Geriatric Oncology (SIOG). Lancet Oncol 2021; 22:e327-e340. [PMID: 34000244 DOI: 10.1016/s1470-2045(20)30741-5] [Citation(s) in RCA: 103] [Impact Index Per Article: 34.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 11/27/2020] [Accepted: 12/02/2020] [Indexed: 01/01/2023]
Abstract
Breast cancer is increasingly prevalent in older adults and is a substantial part of routine oncology practice. However, management of breast cancer in this population is challenging because the disease is highly heterogeneous and there is insufficient evidence specific to older adults. Decision making should not be driven by age alone but should involve geriatric assessments plus careful consideration of life expectancy, competing risks of mortality, and patient preferences. A multidisciplinary taskforce, including members of the European Society of Breast Cancer Specialists and International Society of Geriatric Oncology, gathered to expand and update the previous 2012 evidence-based recommendations for the management of breast cancer in older individuals with the endorsement of the European Cancer Organisation. These guidelines were expanded to include chemotherapy toxicity prediction calculators, cultural and social considerations, surveillance imaging, genetic screening, gene expression profiles, neoadjuvant systemic treatment options, bone-modifying drugs, targeted therapies, and supportive care. Recommendations on geriatric assessment, ductal carcinoma in situ, screening, primary endocrine therapy, surgery, radiotherapy, adjuvant systemic therapy, and secondary breast cancer were updated.
