Axilla View of Mammography in Preoperative Axillary Lymph Node Evaluation of Breast Cancer Patients: A Pilot Study. Clin Breast Cancer 2024; 24:e51-e60. [PMID: 37925360 DOI: 10.1016/j.clbc.2023.10.004] [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: 07/07/2023] [Revised: 09/23/2023] [Accepted: 10/15/2023] [Indexed: 11/06/2023]
Abstract
PURPOSE This study aimed to explore a novel position of mammography named axilla view in axillary lymph node (ALN) evaluation in breast cancer. PATIENTS AND METHODS Patients were prospectively enrolled and scheduled for mammography before surgery. Investigated imaging patterns included mediolateral oblique (2D-MLO) and axilla view (2D-axilla) of mammography, and axilla view of digital breast tomosynthesis (3D-axilla). The correlation of ALN numbers between imaging and pathology was analyzed. Diagnostic performance was analyzed via AUC. RESULTS 75 patients were included. A larger and clearer axillary region was displayed in axilla view. The total number of ALNs detected under 2D/3D-axilla view was significantly higher than that under 2D-MLO view (4.6 vs. 2.5, P < .001; 5.6 vs. 4.6, P = .034). Correlations between number of positive ALNs detected under 2D/3D-axilla view and pathologically confirmed metastatic ALNs were stronger than 2D-MLO view (Pearson correlation coefficients: 0.7084,0.7044 and 0.4744). The proportion of cases with ≥5 positive ALNs detected under 3D-axilla view was significantly higher than that under 2D-MLO (38.2% vs. 14.7%, P = .028). The overweight and obese group showed a higher AUC value than the underweight and lean group in ALN evaluation, although not significantly (2D-MLO: 0.7643 vs. 0.6458, P = .2656; 2D-axilla: 0.8083 vs. 0.6586, P = .1522; 3D-axilla: 0.8045 vs. 0.6615, P = .1874). This difference was more pronounced in axilla view. CONCLUSION Axilla view exhibited advantages over conventional MLO view in the extent of axilla displayed by mammography in breast cancer. Further studies with larger sample sizes are needed.

Evaluating the Necessity for Routine Sentinel Lymph Node Biopsy in Postmenopausal Patients Being Treated for Clinically Node Negative Breast Cancer the Era of RxPONDER. Clin Breast Cancer 2023:S1526-8209(23)00080-0. [PMID: 37076364 DOI: 10.1016/j.clbc.2023.03.011] [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: 03/05/2023] [Revised: 03/23/2023] [Accepted: 03/25/2023] [Indexed: 04/21/2023]
Abstract
INTRODUCTION Traditionally, sentinel lymph node biopsy (SLNB) was performed to inform adjuvant chemotherapy prescription and prognosis in breast cancer. Following RxPONDER, the OncotypeDX Recurrence Score (RS) guides adjuvant chemotherapy prescription for all postmenopausal patients with estrogen receptor positive, human epidermal growth factor receptor-2 negative (ER+/HER2-) breast cancer with 0 to 3 positive lymph nodes (0-3 + LN). AIMS To establish the oncological safety of omitting SLNB in postmenopausal patients with ER+/HER2- breast cancer indicated to undergo SLNB and to evaluate the primary determinants of chemotherapy prescription for these patients. PATIENTS AND METHODS A retrospective cohort study was undertaken. Cox regression and Kaplan-Meier analyses were performed. Data analytics was performed using SPSS v26.0. RESULTS Five hundred and seventy five consecutive patients were included (mean age: 66.5 years, range: 45-96). The median follow-up was 97.2 months (range: 3.0-181.6). Of the 575 patients, just 12 patients had positive SLNB (SLNB+) (2.1%). Using Kaplan-Meier analyses, SLNB+ failed to impact recurrence (P = .766) or mortality (P = .310). However, using Cox regression analyses, SLNB+ independently predicted poorer disease-free survival (hazard ratio: 1.001, 95% confidence interval (95% CI): 1.000-1.001, P = .029). Logistic regression analysis identified RS as the sole predictor of chemotherapy prescription (odds ratio: 1.171, 95% CI: 1.097-1.250, P < .001). CONCLUSION Omitting SLNB may be safe and justifiable in postmenopausal patients with ER+/HER2- breast cancer with clinically negative axillae. Following RxPONDER, RS is the most important guide of chemotherapy use in these patients and SLNB may be less important than previously perceived. Prospective, randomized clinical trials are required to fully establish the oncological safety of omitting SLNB in this setting.

Contemp Clin Trials 2023; 128:107135. [PMID: 36868347 DOI: 10.1016/j.cct.2023.107135] [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: 09/24/2022] [Revised: 02/12/2023] [Accepted: 02/22/2023] [Indexed: 03/05/2023]
Abstract
BACKGROUND Despite increasing focus on conducting cancer clinical trials in older adults, it is unclear whether such evidence influences practice patterns. We aimed to estimate the impact of cumulative evidence from older adult-specific trial results from the CALGB 9343 and PRIME II trials that found post-lumpectomy irradiation has little benefit among older adults with early-stage breast cancer (ESBC). METHODS Patients diagnosed with ESBC between 2000 and 2018 were identified from the SEER registry data. We examined the incremental immediate effect, incremental average yearly effect, and cumulative effect of a series of CALGB 9343 and PRIME II results on the utilization level of post-lumpectomy irradiation. We conducted difference-in-differences analyses, comparing those aged 70 or older vs. <65 years old. RESULTS The initial 5-year CALGB 9343 results in 2004 led to a significant immediate (-0.038, 95% CI: -0.064, -0.012) and average yearly decrease (-0.008, 95% CI: -0.013, -0.003) in the probability of irradiation use among those aged 70 or older compared to those below 65 years of age. 11-year CALGB 9343 results in 2010 significantly accelerated the average yearly effect by 1.7 percentage points (95% CI: -0.030, -0.004). The other later results did not significantly change the time trend. The cumulative effect of all results between 2004 and 2018 was -26.3 percentage points (95% CI: -0.29, -0.24). CONCLUSION Cumulative evidence from older adult-specific trials in ESBC led to decreasing use of irradiation over time among elderly patients. The rate of decrease after the initial results was accelerated by long-term follow-up results.

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
Radiation enteritis is the most common complication of radiotherapy in patients with pelvic malignancies. Thus, the radioprotective activity of the total hydro-alcoholic extract (BGE) and the ethyl acetate soluble fraction (EAF) of Brownea grandiceps leaves was evaluated against ϒ-radiation-induced enteritis in rats. (BGE) and (EAF) were characterized using HPLC-PDA-ESI-MS/MS analysis. The total phenolic and flavonoid contents were also quantified. In vivo administration of (BGE) (400 mg/kg) and (EAF) (200 & 400 mg/kg) prevented intestinal injury and maintained the mucosal integrity of irradiated rats through increasing villi length and promoting crypt regeneration. Also, (EAF) showed more potent antioxidant activity than (BGE) through reduction of MDA level and enhancement of GSH content and catalase enzyme activity. (BGE) and (EAF) down-regulated intestinal NF-κB expression leading to diminished expression of downstream inflammatory cytokine TNF-α. Moreover, (EAF) markedly reduced the expression of profibrotic marker TGF-β1. Seventy-nine compounds were tentatively identified, including flavonoids, proanthocyanidins, polar lipids and phenolic acids. (EAF) showed significantly higher total phenolic and flavonoid contents, as compared to (BGE). Results revealed remarkable radioprotective activity of (BGE) and (EAF), with significantly higher activity for (EAF). The chemical constituents of (BGE) and (EAF) strongly supported their radioprotective activity. To the best of our knowledge, the present study describes for the first time the radioprotective activity of B. grandiceps leaves in relation to its secondary metabolome fingerprint; emphasizing the great promise of B. grandiceps leaves, especially (EAF), to be used as natural radio-protective agent.

Abstract
BACKGROUND Professional organizations recently set guidelines for avoiding surgeries of low utility and overutilization for the Choosing Wisely campaign. These include re-excision for invasive cancer close to margins, double mastectomy in patients with unilateral breast cancer, axillary lymph node dissection in patients with limited nodal disease, and sentinel lymph node biopsy (SLNB) in patients ≥70 years with early-stage breast cancer. Variable adherence to these recommendations led us to evaluate implementation rates of low-value surgical guidelines at a safety-net hospital. METHODS We retrospectively analyzed breast cancer patients who underwent surgery from 2015 to 2020. Each patient was assessed for eligibility for omission of the listed surgeries. Trends were evaluated by cohorts before and after a fellowship-trained breast surgeon joined the faculty in 2018. Outcomes were compared using Fisher's exact test. RESULTS Among 195 patients, none underwent re-excision for close margins of invasive cancer. Only 6.7% of patients (3/45) received contralateral mastectomy and 1.8% of eligible patients (3/169) received axillary lymph node dissection. Overall, 60% of patients ≥ 70 years with stage 1 hormone-positive breast cancer (9/15) received SLNB. There was a downward trend from 71% of eligible patients receiving SLNB in 2015-2018 to 50% in 2019-2020. CONCLUSIONS De-implementation of traditional surgical practices, deemed as low-value care, toward newer guidelines is achievable even at community hospitals serving a low socioeconomic community. By avoiding overtreatment, hospitals can achieve effective resource allocation which allow for social distributive justice among patients with breast cancer and ensure strategic use of scarce health economic resources while preserving patient outcomes.

Abstract
Background Sentinel lymph node biopsy (SLNB) provides staging information and guides adjuvant therapy in early breast cancer (EBC). Routine SLNB in oncogeriatricians with low-risk EBC remains controversial. Aims To evaluate axillary management in elderly patients diagnosed with oestrogen receptor positive (ER+), clinically lymph node negative (cLN-) EBC, and to assess whether SLNB affects further axillary management or adjuvant chemotherapy (ACTX) decision making. Methods Female patients aged > 65 years, diagnosed with ER+, human epidermal growth factor receptor-2 negative (HER2-), and cLN- breast cancer (BC), who underwent surgery and SLNB were included. Clinicopathological predictors of ACTX and completion axillary lymph node dissection (CALND) were determined. Kaplan-Meier analyses assessed survival outcomes. Results A total of 253 patients were included (median age: 72 years, range: 66-90), all underwent SLNB; 50 (19.8%) had lymphatic metastasis on SLNB (SLNB+). Of these, 19 proceeded to CALND (38.0%), 10 (52.6%) of whom had further axillary disease (ALND+). 20 of the 50 SLNB+ patients received ACTX (40.0%) as did 31 of the 203 SLNB- patients (15.2%) (P < .001). Oncotype DX (ODX) testing was utilized in 82 cases (32.8%). Younger age (P < .001), SLNB+ (P < .001) and ODX score (P = .003) were all associated with ACTX prescription. ODX > 25 (OR: 4.37, 95% CI: 1.38-13.80, P = .012) independently predicted receiving ACTX. Receiving ACTX and proceeding to CALND did not improve disease-free (P = .485 and P = .345) or overall survival (P = .981 and P = .646). Conclusions Routine SNLB may not be necessary in elderly patients diagnosed with ER+, cLN- EBC. Future oncogeriatric practice is likely to see genomic testing guiding ACTX prescription in this group.

Abstract
IMPORTANCE Overtreatment of early-stage breast cancer with favorable tumor biology in older patients may be harmful without affecting recurrence and survival. Guidelines that recommend deimplementation of sentinel lymph node biopsy (SLNB) (Choosing Wisely) and radiotherapy (RT) (National Comprehensive Cancer Network) have been published. OBJECTIVE To describe the use rates and association with disease recurrence of SLNB and RT in older women with breast cancer. DESIGN, SETTING, AND PARTICIPANTS This cohort study obtained patient and clinical data from an integrated cancer registry and electronic health record of a single health care system in Pennsylvania. The cohort was composed of consecutive female patients 70 years or older who were diagnosed with early-stage, estrogen receptor-positive, ERBB2 (formerly HER2)-negative, clinically node-negative breast cancer from January 1, 2010, to December 31, 2018, who were treated at 15 community and academic hospitals within the health system. EXPOSURES Sentinel lymph node biopsy and adjuvant RT. MAIN OUTCOMES AND MEASURES Primary outcomes were 5-year locoregional recurrence-free survival (LRFS) rate and disease-free survival (DFS) rate after SLNB and after RT. Secondary outcomes included recurrence rate, subgroups that may benefit from SLNB or RT, and use rate of SLNB and RT over time. Propensity scores were used to create 2 cohorts to separately evaluate the association of SLNB and RT with recurrence outcomes. Cox proportional hazards regression model was used to estimate hazard ratios (HRs). RESULTS From 2010 to 2018, a total of 3361 women 70 years or older (median [interquartile range {IQR}] age, 77.0 [73.0-82.0] years) with estrogen receptor-positive, ERBB2-negative, clinically node-negative breast cancer were included in the study. Of these women, 2195 (65.3%) received SLNB and 1828 (54.4%) received adjuvant RT. Rates of SLNB steadily increased (1.0% per year), a trend that persisted after the 2016 adoption of the Choosing Wisely guideline. Rates of RT decreased slightly (3.4% per year). To examine patient outcomes and maximize follow-up time, the analysis was limited to cases from 2010 to 2014, identifying 2109 patients with a median (IQR) follow-up time of 4.1 (2.5-5.7) years. In the propensity score-matched cohorts, no association was found between SLNB and either LRFS (HR, 1.26; 95% CI, 0.37-4.30; P = .71) or DFS (HR, 1.92; 95% CI, 0.86-4.32; P = .11). In addition, RT was not associated with LRFS (HR, 0.33; 95% CI, 0.09-1.24; P = .10) or DFS (HR, 0.99; 95% CI, 0.46-2.10; P = .97). Subgroup analysis showed that stratification by tumor grade or comorbidity was not associated with LRFS or DFS. Low absolute rates of recurrence were observed when comparing the groups that received SLNB (3.5%) and those that did not (4.5%) as well as the groups that received RT (2.7%) and those that did not (5.5%). CONCLUSIONS AND RELEVANCE This study found that receipt of SLNB or RT was not associated with improved LRFS or DFS in older patients with ER-positive, clinically node-negative breast cancer. Despite limited follow-up time and wide 95% CIs, this study supports the continued deimplementation of both SLNB and RT in accordance with the Choosing Wisely and National Comprehensive Cancer Network guidelines.

Ann Surg Oncol 2021; 28:5158-5163. [PMID: 33751295 DOI: 10.1245/s10434-021-09618-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 01/04/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND Patients 65 years old or older with early endocrine-responsive breast cancer have many treatment options, including no radiation. This study aimed to evaluate treatment preference when intraoperative radiation therapy (IORT) is offered in this population. METHODS The study reviewed patients 65 years old or older with a diagnosis of early-stage endocrine-responsive breast cancer in 2016-2019 at a single hospital in a large integrated health care system. Electronic medical records of multidisciplinary breast tumor board discussion, treatment options documented by the treatment team, and final treatment offered were reviewed. Variables including age at biopsy, language, endocrine treatment, and comorbidities were collected. Regression analysis was used to evaluate for variables associated with patients' choice regarding radiation treatment. RESULTS The institutional IORT guidelines were met by 63 patients in the described age group who had a documented offer of all radiation treatment options. The median age of the patients was 70 years (interquartile range 63-77 years). Overall, 74.6% of the patients chose IORT, and 14.3% opted for whole-breast irradiation. Only 4.8% chose to omit radiation after breast-conserving surgery, and 6.3% chose mastectomy. The patients who chose IORT were more likely to receive endocrine treatment (odds ratio 3.70; p = 0.03). Age, race, language, and comorbidities were not associated with preference for IORT (p < 0.05). CONCLUSIONS Patients 65 years old or older with early-stage endocrine-responsive breast cancer preferred to have IORT despite counsel about the lack of survival benefit. This study suggests that local cancer control with the convenient radiation delivery method is important to the described patient population.

Long-term outcome and axillary recurrence in elderly women (≥70 years) with breast cancer: 10-years follow-up from a matched cohort study. Eur J Surg Oncol 2021; 47:1593-1600. [PMID: 33685727 DOI: 10.1016/j.ejso.2021.02.027] [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: 01/28/2021] [Revised: 02/12/2021] [Accepted: 02/22/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND AND OBJECTIVES The oncological benefit of axillary surgery (AS), with sentinel lymph node biopsy (SLNB) or axillary dissection (ALND), in elderly women affected by breast cancer (BC) is controversial. We evaluated AS trends over a 10-year follow-up period as well as locoregional and survival outcomes in this subset of patients. METHODS Patients aged 70 years or older, treated between 1994 and 2008, were selected and divided in two groups, depending on whether or not AS was performed. A (1:1) matched analysis for all relevant clinicopathological features was performed. Outcomes were analyzed using the Kaplan-Meier method and univariate Cox-proportional hazard ratio analysis. RESULTS A total of 1.748 patients were identified and stratified by age (70-74, 75-79, 80-84). A matched analysis was performed for 252 patients: 122 who underwent AS and 122 who did not. At 10-year follow-up, ipsilateral breast tumor recurrence, distant metastasis and contralateral BC were similar, p = 0.83, p = 0.42 and p = 0.28, respectively. In the no-AS group, a significant increased risk of axillary lymph-node recurrence was identified at 5- and confirmed at 10-years (p = 0.038), without impact on overall survival at 5- and 10-years (p = 0.52). In the non-AS group, higher rate of axillary recurrence at 10-years was observed in patients with poorly differentiated (24.1%, 95% CI 7.2-46.2), highly proliferative (Ki67 ≥ 20%: 17.1%, 95% CI 0.6-33.3) and luminal B tumors (16.8%, 95% CI 5.9-35.5). CONCLUSIONS Axillary staging in elderly women does not impact long-term survival. Tailoring surgery according to tumor biology and age may improve locoregional outcome.

Abstract
Objective: The application of sentinel lymph node biopsy (SLNB) in elderly patients with early breast cancer remains somewhat controversial. This study aimed to establish individualized nomograms to predict survival outcomes of elderly patients with and without SLNB and find out which patients could avoid SLNB. Methods: A total of 39,962 ≥70-year-old patients diagnosed with T1–T2 breast cancer in 2010–2015 were included from the Surveillance, Epidemiology, and End Results (SEER) program and were divided into the training set (n = 29,971) and the validation set (n = 9,991). Axillary surgery was not specified in the SEER database, and we defined removing one to five lymph nodes as SLNB. Survival analysis was performed using the Kaplan–Meier plot and log-rank test. Multivariate Cox analysis was utilized to identify risk factors for overall survival (OS) and breast-cancer-specific survival (BCSS). Nomograms and a risk stratification model were constructed. Results: In the training set, patients with SLNB had better OS (adjusted HR 0.57, P < 0.001) and BCSS (adjusted HR 0.55, P < 0.001) than patients without SLNB. Multivariate COX analysis identified age, marital status, grade, subtype, T stage, and radiation as independent risk factors for OS and BCSS in both SLNB and non-SLNB groups (all P < 0.05). They were subsequently incorporated to establish nomograms to predict 3- and 5-year OS and BCSS for patients with or without SLNB. The concordance index ranged from 0.687 to 0.820, and calibration curves in the internal set and external set all demonstrated sufficient accuracies and good predictive capabilities. Further, we generated a risk stratification model which indicated that SLNB improved OS and BCSS in high-risk group (OS: HR 0.49, P < 0.001; BCSS: HR 0.54, P < 0.001), but not in the low-risk group (all P > 0.05). Conclusion: Well-validated nomograms and a risk stratification model were constructed to evaluate survival benefit from SLNB in elderly patients with early-stage breast cancer. SLNB was important for patients in the high-risk group but could be omitted in the low-risk group without sacrificing survival. This study could assist clinicians and elderly patients to weigh the risk–benefit of SLNB and make individualized decisions. We look forward to more powerful evidence from prospective trials.

Long-term Impact of CALGB 9343 on Radiation Utilization. J Surg Res 2020; 256:577-583. [PMID: 32805580 DOI: 10.1016/j.jss.2020.07.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 07/07/2020] [Accepted: 07/11/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND The results of the Cancer and Leukemia Group B (CALGB) 9343 trial showed that radiation therapy (RT) did not improve survival for women older than 70 y with early-stage estrogen receptor + breast cancer treated with breast conserving surgery and adjuvant endocrine therapy. In 2005, guidelines were modified to allow for RT omission; however, minimal change in clinical practice has occurred. The aim of this study was to determine if CALGB long-term follow-up data have affected RT utilization, and to characterize the population still receiving RT after breast conserving surgery. METHODS The Surveillance, Epidemiology, and End Results-Medicare database was used to identify women diagnosed with early-stage breast cancer from 2004 to 2015 who matched the CALGB 9343 inclusion criteria. Multivariate logistic regression was carried out to identify the factors that affect the receipt of radiation therapy. We also plotted the overall use of RT over time juxtaposed with the temporal trends of CALGB 9343 clinical trial data, guideline recommendations, and publishing of long-term survival data. RESULTS The study cohort included 25,723 Medicare beneficiaries, of whom 20,328 (79%) received RT and 5395 (21%) did not receive RT. In a multivariate model, the frequency of RT omission increased over time, with those diagnosed in year 2015 being 2.72 times more likely to omit RT compared with those diagnosed in 2004 (95% confidence interval 2.31-3.19). CONCLUSIONS This study investigated the impact of long-term CALGB 9343 data on clinical practice. The results of this study support results from previous studies, extend the dates of analysis, and indicate that after long-term follow-up of CALGB 9343 data, RT was less used, but overall trends did not dramatically decrease.

Does persistent use of radiation in women > 70 years of age with early-stage breast cancer reflect tailored patient-centered care? Breast Cancer Res Treat 2020; 180:801-807. [PMID: 32125557 PMCID: PMC7474974 DOI: 10.1007/s10549-020-05579-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 02/18/2020] [Indexed: 01/23/2023]
Abstract
PURPOSE Randomized controlled trials demonstrate that omission of radiation therapy (RT) in older women with early-stage cancer undergoing breast conserving surgery (BCS) is an "acceptable choice." Despite this, high RT rates have been reported. The objective was to evaluate the impact of patient- and system-level factors on RT rates in a contemporary cohort. METHODS Through the National Cancer Data Base, we identified women with clinical stage I estrogen receptor-positive breast cancer who underwent BCS (n = 84,214). Multivariable logistic regression identified patient, tumor, and system-level factors associated with RT. Joinpoint regression analysis calculated trends in RT use over time stratified by age and facility-type, reporting annual percent change (APC). RESULTS RT rates decreased from 2004 (77.2%) to 2015 (64.3%). The decline occurred earliest and was most pronounced in older women treated at academic facilities. At academic facilities, the APC was - 5.6 (95% CI - 8.6, - 2.4) after 2009 for women aged > 85 years, - 6.4 (95% CI - 9.0, - 3.8) after 2010 for women aged 80 - < 85 years, - 3.7 (95% CI - 5.6, - 1.9) after 2009 for women aged 75 - < 80, and - 2.4 (95% CI, - 3.1, - 1.6) after 2009 for women aged 70 - < 75. In contrast, at community facilities rates of RT declined later (2011, 2012, and 2013 for age groups 70-74, 75-79, and 80-84 years). CONCLUSIONS RT rates for older women with early-stage breast cancer are declining with patient-level variation based on factors related to life expectancy and locoregional recurrence. Facility-level variation suggests opportunities to improve care delivery by focusing on barriers to de-implementation of routine use of RT.
