Abstract
INTRODUCTION To analyze the cancer burden in the United States, researchers are relying on the Surveillance, Epidemiology, and End Results (SEER) Program. Our objective was to analyze differences in cancer outcome between Commission on Cancer (CoC)-accredited and non-accredited facilities. METHODS The SEER database was queried for diagnosis years 2018 and 2019. Only analytic cases were included. Observed survival was calculated using the Kaplan-Meier method for all cancer sites, stratified by accreditation status. Univariate analyses were performed to quantify differences in survival between cancer cases in CoC-accredited and non-CoC-accredited facilities. Cancers of interest were chosen based on statistical significance (p < 0.01) and clinical significance (> 25% difference in end survival). Multivariate analyses were conducted on cancers of interest. RESULTS Overall, there were 602,185 cases from CoC-accredited facilities and 198,492 from non-CoC-accredited facilities. 5 of 59 solid organ cancers showed statistically and clinically significant reductions in survival in non-accredited facilities (lung and bronchus: 27.9%; liver: 41.1%; esophagus: 30.4%; pancreas: 32.7%; intrahepatic bile duct: 39.4%). Multivariate analysis on these 5 cancers was performed. CoC accreditation was a statistically significant variable decreasing the hazard in all 5 cancers (hazard ratio 0.86-0.91; all p-values <0.005). All these cancers demand resource-intensive treatment. CONCLUSION Accreditation has a significant impact on survival in 5/59 solid organ cancers. Although accredited facilities may be better apt to handle these cancer cases, the survival in most cancers is not significantly affected by accreditation. However, examining longer-term endpoints elucidate further nuances. Herein, CoC accreditation was found to be an independent variable impacting 2-year survival for a minority of cancers.

Çeli K Y, Çeli K SŞ, Sarıköse S, Arslan HN. Evaluation of financial toxicity and associated factors in female patients with breast cancer: a systematic review and meta-analysis. Support Care Cancer 2023; 31:691. [PMID: 37953376 DOI: 10.1007/s00520-023-08172-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 11/07/2023] [Indexed: 11/14/2023]
Abstract
PURPOSE These systematic review and meta-analysis were conducted to discuss the financial toxicity (FT) level among breast cancer (BC) patients and the associated demographic and economic factors. METHODS A systematic review and meta-analysis of single means were used by following the Joanna Briggs Institute guidelines and PRISMA guidance. Untransformed means (MRAW) were used to estimate the confidence interval for individual studies, while I2 and tau2 statistics were used to examine heterogeneity among pooled studies. Electronic databases were PubMed, CINAHL, Web of Science, Scopus, Cochrane Library, Ovid MEDLINE(R), Science Direct, and Turkish databases were used to find relevant studies published in the last 15 years (between 2008 and 2023). RESULTS A total of 50 studies were reviewed in the systematic review, and 11 were included in the overall and subgroup meta-analyses. The majority of reviewed studies were from the USA (38 studies), while there were four studies from China and eight studies from other countries having different types of health systems. The overall estimated FT level based on 11 pooled studies was 23.19, meaning mild level FT in the range of four categories (no FT score > 25, mild FT score 14-25, moderate FT score 1-13, and severe FT score equal to 0), with a 95% CI of 20.66-25.72. The results of subgroup meta-analyses showed that the estimated FT levels were higher among those patients who were single, with lower education levels, stage 3 patients, younger, lower income, unemployed, and living in other countries compared to those who were married, more educated, and stages 1 and 2 patients, more aged, more income, employed, and patients in the USA. CONCLUSION The cost-effectiveness of the treatment strategies of BC depends on the continuity of care. However, FT is one of the leading factors causing BC patients to use the required care irregularly, and it has a negative effect on adherence to treatment. So, removing the economic barriers by taking appropriate measures to decrease FT will increase the efficiency of already allocated resources to BC treatments and improve the health outcomes of BC patients.

Abstract
Due to the COVID-19 pandemic, and ensuing overcrowding in the French health system, management of patients with COVID-19 was given priority over that of patients with other pathologies, including chronic diseases. The aim of this study was to study the impact of COVID-19 on the stage of discovery of cancers diagnosed in the context of an organized breast cancer screening programme, as well as the impact on time to treatment. All women diagnosed with cancer in the Côte d'Or via organized breast cancer screening (first or second reading) from January 1, 2019 to December 31, 2020 were included in this study. Using data from pathological laboratories, clinical centers, and the breast and gynecological cancer registry of the Côte d'Or, France, we collected socio-demographic, clinical and treatment data on all patients. We compared data from the year 2019 (before-Covid) with the year 2020 (Covid). We did not observe a significant difference in the stage of breast cancer at discovery, or in time to treatment. However, the number of invasive cancers and the clinical size of in situ cancers both increased in 2020. Although these results are reassuring, continued monitoring is needed to determine the downstream effects of the pandemic.

BMC Health Serv Res 2022; 22:1566.

Abstract
BACKGROUND We aimed to investigate the association between fragmented cancer care in the early phase after cancer diagnosis and patient outcomes using national insurance claim data. METHODS From a nationwide sampled cohort database, we identified National Health Insurance beneficiaries diagnosed with gastric cancer (ICD-10: C16) in South Korea during 2005-2013. We analyzed the results of a multiple logistic regression analysis using the generalized estimated equation model to investigate which patient and institution characteristics affected fragmented cancer care during the first year after diagnosis. Then, survival analysis using the Cox proportional hazard model was conducted to investigate the association between fragmented cancer care and five-year mortality. RESULTS Of 2879 gastric cancer patients, 11.9% received fragmented cancer care by changing their most visited medical institution during the first year after diagnosis. We found that patients with fragmented cancer care had a higher risk of five-year mortality (HR: 1.310, 95% CI: 1.023-1.677). This association was evident among patients who only received chemotherapy or radiotherapy (HR: 1.633, 95% CI: 1.005-2.654). CONCLUSIONS Fragmented cancer care was associated with increased risk of five-year mortality. Additionally, changes in the most visited medical institution occurred more frequently in either patients with severe conditions or patients who mainly visited smaller medical institutions. Further study is warranted to confirm these findings and examine a causal relationship between fragmented cancer care and survival.

Abstract
OBJECTIVES We studied both the independent and combined effects of the places of biopsy and treatment on the treatment time interval based on a population-based study. METHODS We analysed the proportion of patients having a treatment time interval higher than the EUSOMA recommendation of 6 weeks, as a function of the number and the type of care centres the patients attended, from a French population-based regional cohort of women treated in 2015 for an incident invasive non-metastatic cancer (n = 505). RESULTS About 33% [95% CI: 27; 38] of patients had a treatment time interval higher than 6 weeks. About 48% of the patients underwent their biopsy and their initial treatment in the different centres. Results from multivariable analyses supported the impact of the type and number of centres attended on the proportion of time intervals over 6 weeks. This proportion was higher among patients with biopsy and treatment in different centres and among patients treated in a university hospital. CONCLUSION We pointed out the independent impact of the type and the number of care centres the patients attended, from biopsy to first treatment, on the treatment time interval, which is a well-known prognosis factor.

Abstract
BACKGROUND Delays between breast cancer diagnosis and surgery are associated with worsened survival. Delays are more common in urban-residing patients, although factors specific to surgical delays among rural and urban patients are not well understood. METHODS We used a 100% sample of fee-for-service Medicare claims during 2007-2014 to identify 238,491 women diagnosed with early-stage breast cancer undergoing initial surgery and assessed whether they experienced biopsy-to-surgery intervals > 90 days. We employed multilevel regression to identify associations between delays and patient, regional, and surgeon characteristics, both in combined analyses and stratified by rurality of patient residence. RESULTS Delays were more prevalent among urban patients (2.5%) than rural patients (1.9%). Rural patients with medium- or high-volume surgeons had lower odds of delay than patients with low-volume surgeons (odds ratio [OR] = 0.71, 95% confidence interval [CI] = 0.58-0.88; OR = 0.74, 95% CI = 0.61-0.90). Rural patients whose surgeon operated at ≥ 3 hospitals were more likely to experience delays (OR = 1.29, 95% CI = 1.01-1.64, Ref: 1 hospital). Patient driving times ≥ 1 h were associated with delays among urban patients only. Age, black race, Hispanic ethnicity, multimorbidity, and academic/specialty hospital status were associated with delays. CONCLUSIONS Sociodemographic, geographic, surgeon, and facility factors have distinct associations with > 90-day delays to initial breast cancer surgery. Interventions to improve timeliness of breast cancer surgery may have disparate impacts on vulnerable populations by rural-urban status.

Abstract
Purpose Breast cancer outcomes are impaired by both delays and disparities in treatment. This study was performed to assess their relationship and to provide a tool to predict patient socioeconomic factors associated with risk for delay. Methods The National Cancer Database was reviewed between 2004 and 2017 for patients with non-metastatic breast cancer managed with upfront surgery. Times to treatment were measured from the date of diagnosis. Patient, tumor, and treatment factors were assessed with attention paid to sociodemographic variables. Results 514,187 patients remained after exclusions, with 84.3% White, 10.8% Black, 3.7% Asian, and Hispanics comprising 5.6% of the cohort. Medicaid and uninsured patients had longer mean adjusted time to surgery (≥ 46 days) versus private (36.7 days), Medicare (35.9 days), or other governmental insurance (39.8 days). After adjustment, Black race and Hispanic ethnicity were most impactful, adding 6.0 and 6.4 preoperative days, 10.9 and 11.5 days to chemotherapy, 11.1 and 9.1 days to radiation, and 12.5 and 8.9 days to endocrine therapy, respectively. Income, education, and insurance, among other factors, also affected delay. A nomogram, including race and sociodemographic factors, was created to predict the risk of preoperative delay. Conclusion Significant disparities exist in timeliness of care for factors, including but not limited to, race and ethnicity. Although exact causes cannot be discerned, these data indicate population subsets whose intervals of care risk being longer than those specified by national quality standards. The nomogram created here may help direct resources to those at highest risk of incurring a treatment delay.

Abstract
INTRODUCTION The Commission on Cancer/National Quality Forum breast radiotherapy quality measure establishes that for women < 70 years, adjuvant radiotherapy after breast conserving surgery (BCS) should be started < 1 year from diagnosis. This was intended to prevent accidental radiotherapy omission or delay due to a long interval between surgery and chemotherapy completion, when radiation is delivered. However, the impact on patients not receiving chemotherapy, who proceed from surgery directly to radiotherapy, remains unknown. PATIENTS AND METHODS Patients aged 18-69, diagnosed with stage I-III breast cancer as their first and only cancer diagnosis (2004-2016), having BCS, for whom this measure would be applicable, were reviewed from the National Cancer Database. RESULTS Among 308,521 patients, the median age was 57.0 years, and > 99% of all patients were compliant with the measure. The cohort of interest included 186,650 (60.5%) patients not receiving chemotherapy, with a mean age of 57.9 years. Of these, 90.5% received external beam radiotherapy (EBRT) and 9.5% brachytherapy. Among them, 24.9% started radiotherapy > 8 weeks after surgery. In a multivariable model, delay from surgery to radiotherapy increased the hazard ratios for overall survival to 9.0% (EBRT) per month and 3.0% (brachytherapy) per week. CONCLUSION While 99.9% of patients undergoing BCS without chemotherapy remain compliant with the current quality measure, 25% have delays > 8 weeks to start radiation, which is associated with impaired survival. These data suggest that the current quality measure should be dichotomized into two, with or without chemotherapy, in order to impel prompt radiotherapy initiation and maximize outcomes in all patients.

[PMID: 34722372 PMCID: PMC8542807 DOI: 10.18502/ijph.v50i9.7048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 03/20/2021] [Indexed: 01/10/2023]
Abstract
Background: Curative operation is the practical and primary therapy for masses of breast cancers. In contrast, the correlation between the time interval from breast cancer diagnosis to curative surgery and survival is still uncertain. Methods: An electronic literature search was conducted on PubMed/Medline and EMBASE (between Jan 2000 and Jan 2020). Primary endpoints were overall survival (OS) or Disease-Free Survival (DFS). The HR with 95% confidence intervals were calculated using a random-effects or fixed-effects model. Results: The combined HR for OS was 1. 10 (95% CI 1. 08–1. 11; P=0. 000) by fixed-effects model, no statistically significant heterogeneity was found (P=1. 000; I2=0%), and this difference was statistically significant (Z=11. 99; P=0. 000). Conclusion: This meta-analysis showed a significant adverse association between more prolonged time to surgery (TTS) and lower overall survival in patients with breast cancer. It is reasonable to minimize that interval between diagnosis and curative surgery.

Abstract
INTRODUCTION The German rectal study published in 2004 established neoadjuvant chemoradiation as a standard of care for locally advanced rectal cancer and current National Comprehensive Cancer Network guidelines endorse several preoperative regimens. Upfront surgery, however, is considered substandard care. In the era of evolving treatment paradigms for locally advanced rectal cancer, we sought to assess trends and predictors of receipt of upfront surgery for stage II to III rectal cancer. METHODS The National Cancer Database was used to identify patients diagnosed with clinical stage II to III rectal adenocarcinoma between 2006 and 2016. Multivariable logistic regression defined adjusted odds ratios and associated 95% confidence intervals of receipt of upfront definitive surgery. The timing of upfront surgery relative to day of diagnosis and rate of receipt of adjuvant therapy were also estimated. RESULTS Among 51,562 patients, 6411 (12.4%) were treated with upfront surgery, which decreased from 16.7% in 2006 to 7.1% in 2016 (P<0.001). The majority of patients (5737 [89.5%]) had definitive surgery after initial diagnostic biopsy. Variables associated with receipt of upfront surgery included female sex, older age, higher comorbidity score, and treatment at a community cancer center (P<0.001). Among those receiving upfront surgery, 2904 (45.3%) received adjuvant radiation therapy, 3218 (50.2%) received adjuvant chemotherapy, and 2559 (39.9%) received no further treatment. CONCLUSIONS The proportion of patients with clinical stage II to III rectal cancer treated with upfront surgery has steadily declined since 2006, however, certain subgroups appear to remain at greater risk. Further research is needed to better elucidate patient and systems-level factors contributing to these disparities in care.

Abstract
PURPOSE To describe clinical and non-clinical factors associated with receipt of breast conserving surgery (BCS) versus mastectomy and time to surgical intervention. METHODS Cross-sectional retrospective study of January 1, 2012 through March 31, 2018 data from the IBM MarketScan Commercial Claims and Encounter and Medicare Supplemental Databases. Area Health Resource Files provided non-clinical characteristics and sociodemographic data. Eligibility: Female sex, claim(s) with ICD-9-CM or ICD-10-CM diagnosis of non-metastatic invasive breast cancer, > 6 months of continuous insurance pre- and post-diagnosis, evidence of BCS or mastectomy following initial ICD9/10 code diagnosis. Logistic and quantile multivariable regression models assessed the association between clinical and non-clinical factors and the outcome of BCS and time to surgery, respectively. RESULTS A total of 53,060 women were included in the study. Compared to mastectomy, BCS was significantly associated with older age (ORs: 1.54 to 2.99, 95% CIs 1.45 to 3.38; ps < .0001) and higher community density of medical genetics (OR: 5.88, 95% CIs 1.38 to 25.00; p = 0.02) or obstetrics and gynecology (OR: 1.13, 95% CI 1.02 to 1.25; p = .02) physicians. Shorter time-to-BCS was associated with living in the South (-2.96, 95% CI -4.39 to -1.33; p < .0001). Longer time-to-BCS was associated with residence in more urban (4.18, 95% CI 0.08 to 8.29; p = 0. 05), educated (9.02, 95% CI 0.13 to 17.91; p = 0.05), or plastic-surgeon-dense (4.62, 95% CI 0.50 to 8.73; p = 0.03) communities. CONCLUSIONS Clinical and non-clinical factors are associated with adoption of BCS and time to treatment, suggesting opportunities to ensure equitable and timely care.

Abstract
In the care of patients with operable breast cancer, there has been a shift toward increasing use of neoadjuvant therapy. There are benefits to neoadjuvant therapy, such as monitoring for response, as well as an increased rate of breast conservation and reduction of potential morbidity associated with breast surgery, including axillary management. Among patients with highly proliferative tumors, such as HER2-positive or triple-negative breast cancer, those with residual disease are at higher risk of recurrence, which informs the recommended systemic therapy in the adjuvant setting. For instance, in patients with residual disease after neoadjuvant chemotherapy and HER2-targeted therapy, there is a role for adjuvant trastuzumab emtansine for those with residual disease at the time of surgery. The same holds true regarding the role of adjuvant capecitabine in patients with residual disease after neoadjuvant chemotherapy. With the added complexities of treating patients in the era of the COVID-19 outbreak, additional considerations are critical, including initiation of surgery within an appropriate time from completion of neoadjuvant therapy. National consensus guidelines on time to surgery must be developed to improve measurement and comparison across systems. In addition, there is emerging radiation treatment management research addressing a number of factors, including hypofractionation, role of proton beam therapy, safe omission of radiotherapy, and preoperative radiotherapy with or without drug combination. In this article, the multidisciplinary approach of treating patients with operable breast cancer is highlighted, with updates and future considerations described.

Abstract
Purpose To examine how treatment delays brought on by the COVID-19 pandemic impacted the physical and emotional well-being of physicians treating these patients. Methods A cross-sectional survey of physician breast specialists was posted from April 23rd to June 11th, 2020 on membership list serves and social media platforms of the National Accreditation Program for Breast Centers and the American Society of Breast Surgeons. Physician well-being was measured using 6 COVID-19 burnout emotions and the 4-item PROMIS short form for anxiety and sleep disturbance. We examined associations between treatment delays and physician well-being, adjusting for demographic factors, COVID-19 testing and ten COVID-19 pandemic concerns. Results 870 physicians completed the survey, 61% were surgeons. The mean age of physicians was 52 and 548 (63.9%) were female. 669 (79.4%) reported some delay in patient care as a result of the COVID-19 pandemic. 384 (44.1%) and 529 (60.8%) of physicians scored outside normal limits for anxiety and sleep disturbance, respectively. After adjusting for demographic factors and COVID-19 testing, mean anxiety and COVID-19 burnout scores were significantly higher among physicians whose patients experienced either delays in surgery, adjuvant chemotherapy, radiation, breast imaging or specialty consultation. A multivariable model adjusting for ten physician COVID-19 concerns and delays showed that “delays will impact my emotional well-being” was the strongest concern associated with anxiety, sleep disturbance and COVID-19 burnout factors. Conclusions Breast cancer treatment delays during the initial surge of the COVID-19 pandemic in the United States were associated with a negative impact on physician emotional wellness.

Association between initiation of adjuvant chemotherapy beyond 30 days after surgery and overall survival among patients with triple-negative breast cancer. Int J Cancer 2020; 147:152-159. [PMID: 31721193 PMCID: PMC7317578 DOI: 10.1002/ijc.32788] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Accepted: 10/28/2019] [Indexed: 12/24/2022]
Abstract
Delayed time to chemotherapy (TTC) is associated with decreased outcomes of breast cancer patients. Recently, studies suggested that the association might be subtype‐dependent and that TTC within 30 days should be warranted in patients with triple‐negative breast cancer (TNBC). The aim of the current study is to determine if TTC beyond 30 days is associated with reduced 10‐year overall survival in TNBC patients. We identified all TNBC patients diagnosed between 2006 and 2014 who received adjuvant chemotherapy in the Netherlands. We distinguished between breast‐conserving surgery (BCS) vs. mastectomy given the difference in preoperative characteristics and outcomes. The association was estimated with hazard ratios (HRs) using propensity‐score matched Cox proportional hazard analyses. In total, 3,016 patients were included. In matched patients who underwent BCS (n = 904), 10‐year overall survival was favorable for patients with TTC within 30 days (84.4% vs. 76.9%, p = 0.001). Patients with TTC beyond 30 days were more likely than those with TTC within 30 days to die within 10 years after surgery (HR 1.69 (95% CI 1.22–2.34), p = 0.002). In matched patients who underwent mastectomy (n = 1,568), there was no difference in 10 years overall survival between those with TTC within or beyond 30 days (74.5% vs. 74.7%, p = 0.716), nor an increased risk of death for those with TTC beyond 30 days (HR 1.04 (95% CI 0.84–1.28), p = 0.716). Initiation of adjuvant chemotherapy beyond 30 days is associated with decreased 10 years overall survival in TNBC patients who underwent BCS. Therefore, timelier initiation of chemotherapy in TNBC patients undergoing BCS seems warranted. What's new? Current breast cancer treatment guidelines recommend that chemotherapy is initiated between 6‐12 weeks after surgery. Delayed treatment can lead to poorer outcome, but there's no precise definition of the optimal window. Recent work suggests that for patients with triple negative breast cancer (TNBC), it's best to initiate chemotherapy within 30 days. Here, the authors evaluated outcomes for TNBC patients correlated with time to chemotherapy. They found that in patients undergoing breast‐conserving surgery, an interval of more than 30 days before chemotherapy was associated with decreased survival. If the patient had undergone a mastectomy, a longer delay before chemotherapy did not impact survival.

Abstract
BACKGROUND/OBJECTIVE Delays in times to surgery, chemotherapy, and radiotherapy impair survival in breast cancer patients. Neoadjuvant chemotherapy (NAC) confers equivalent survival to adjuvant chemotherapy (AC), but it remains unknown which approach facilitates faster initiation and completion of treatment. METHODS Women ≥18 years old with nonrecurrent, noninflammatory, clinical stage I-III breast cancer diagnosed between 2004 and 2015 who underwent both surgery and chemotherapy were reviewed from the National Cancer Database. RESULTS Among 155 606 women overall, 28 241 patients received NAC and 127 365 patients received AC. NAC patients had higher clinical T and N stages (35.8% T3/4 vs 4.9% T3/4; 14.4% N2/3 vs 3.7% N2/3). After adjusting for stage and other factors, NAC patients had longer times to begin treatment (36.1 vs 35.4 days adjusted, P = .15), and took significantly longer to start radiotherapy (240.8 vs 218.2 days adjusted, P < .0001), and endocrine therapy (301.6 vs 275.7 days adjusted, P < .0001). Unplanned readmissions (1.2% vs 1.7%), 30-day mortality (0.04% vs 0.01%), and 90-day mortality (0.30% vs 0.08%) were all low and clinically insignificant between NAC and AC. CONCLUSION Compared to patients receiving AC, those receiving NAC do not start treatment sooner. In addition, patients receiving NAC do not complete treatment faster. Although there are clear indications for administering NAC vs AC, rapidity of treatment should not be considered a benefit of giving chemotherapy preoperatively.

Abstract
BACKGROUND Characterization of breast cancer phenotypes has improved our ability to predict breast cancer behavior. Triple-negative (TN) breast cancers have higher and earlier rates of distant events. It has been suggested that this behavior necessitates treating TNs faster than others, including use of neoadjuvant chemotherapy (NACT) if time to surgery is not rapid. METHODS A review of women diagnosed with non-inflammatory, invasive breast cancer was conducted using the National Cancer Database for patients not having NACT, diagnosed between 2010 and 2014. Changes in overall survival due to delay were measured by phenotype. RESULTS Overall, 351,087 patients met the inclusion criteria, including 36,505 (10.4%) TNs, 77.9% hormone receptor-positive (HR+) and 11.7% human epidermal growth factor receptor 2 (HER2)-enriched (HER2+). Phenotype, among other factors, was predictive of treatment delays. Adjusted median days from diagnosis to surgery and chemotherapy were 29.9, 31.6 and 31.5 (p< 0.001), and 72.7, 78.0 and 74.4 (p< 0.001) for TNs, HR+ and HER2+ cancers, respectively. After diagnosis, OS declined for all patients per month of preoperative delay (hazard ratio 1.104; p< 0.001). In models separating or combining surgery and chemotherapy, this survival decline did not vary by breast cancer phenotype (p > 0.3). CONCLUSIONS Delays cause small but measurable effects overall, but the effect on survival does not differ among breast cancer phenotypes. Our data suggest that urgency between diagnosis and surgery or chemotherapy is similar for breast cancers of different subtypes. Although NACT is sometimes advocated solely to avoid treatment delays, this study does not suggest a greater surgical urgency for TNs compared with other breast cancer phenotypes.

Abstract
Background Although treatment delays have been associated with survival impairment for invasive breast cancer, this has not been thoroughly investigated for ductal carcinoma in situ (DCIS). With trials underway to assess whether DCIS can remain unresected, this study was performed to determine whether longer times to surgery are associated with survival impairment or increased invasion. Methods A population-based study of prospectively collected national data derived from women with a clinical diagnosis of DCIS between 2004 and 2014 was conducted using the National Cancer Database. Overall survival (OS) and presence of invasion were assessed as functions of time by evaluating five intervals (≤ 30, 31–60, 61–90, 91–120, 121–365 days) between diagnosis and surgery. Subset analyses assessed those having pathologic DCIS versus invasive cancer on final pathology. Results Among 140,615 clinical DCIS patients, 123,947 had pathologic diagnosis of DCIS and 16,668 had invasive ductal carcinoma. For all patients, 5-year OS was 95.8% and unadjusted median delay from diagnosis to surgery was 38 days. With each delay interval increase, added relative risk of death was 7.4% (HR 1.07; 95% CI 1.05–1.10; P < 0.001). On final pathology, 5-year OS for noninvasive patients was 96.0% (95% CI 95.9–96.1%) versus 94.9% (95% CI 94.6–95.3%) for invasive patients. Increasing delay to surgery was an independent predictor of invasion (OR 1.13; 95% CI 1.11–1.15; P < 0.001). Conclusions Despite excellent OS for invasive and noninvasive cohorts, invasion was seen more frequently as delay increased. This suggests that DCIS trials evaluating nonoperative management, which represents infinite delay, require long term follow up to ensure outcomes are not compromised.

Abstract
BACKGROUND Initiation of adjuvant chemotherapy within 6-12 weeks after mastectomy is recommended by guidelines. The aim of this population-based study was to investigate whether immediate breast reconstruction (IBR) after mastectomy reduces the likelihood of timely initiation of adjuvant chemotherapy. METHODS All patients with breast cancer who had undergone mastectomy and adjuvant chemotherapy between 2012 and 2016 in the Netherlands were identified. Time from surgery to adjuvant chemotherapy was categorized as within 6 weeks or after more than 6 weeks, within 9 weeks or after more than 9 weeks, and within 12 weeks or after more than 12 weeks. The impact of IBR on the initiation of adjuvant chemotherapy for these three scenarios was estimated using propensity score matching to adjust for treatment by indication bias. RESULTS A total of 6300 patients had undergone primary mastectomy and adjuvant chemotherapy, of whom 1700 (27·0 per cent) had received IBR. Multivariable analysis revealed that IBR reduced the likelihood of receiving adjuvant chemotherapy within 6 weeks (odds ratio (OR) 0·76, 95 per cent c.i. 0·66 to 0·87) and 9 weeks (0·69, 0·54 to 0·87), but not within 12 weeks (OR 0·75, 0·48 to 1·17). Following propensity score matching, IBR only reduced the likelihood of receiving adjuvant chemotherapy within 6 weeks (OR 0·95, 0·90 to 0·99), but not within 9 weeks (OR 0·97, 0·95 to 1·00) or 12 weeks (OR 1·00, 0·99 to 1·01). CONCLUSION Postmastectomy IBR marginally reduced the likelihood of receiving adjuvant chemotherapy within 6 weeks, but not within 9 or 12 weeks. Thus, IBR is not contraindicated in patients who need adjuvant chemotherapy after mastectomy.
