Abstract
PURPOSE Treating early-stage breast cancer (eBC) may delay or prevent subsequent metastatic breast cancer (mBC). In the phase 3 KATHERINE study, women with human epidermal growth factor receptor 2 (HER2)-positive eBC with residual disease following neoadjuvant therapy containing trastuzumab and a taxane experienced 50% reductions in disease recurrence or death when treated with adjuvant trastuzumab emtansine (T-DM1) vs adjuvant trastuzumab. We predicted the population-level impact of adjuvant T-DM1 on mBC occurrence in five European countries (EU5) and Canada from 2021-2030. METHODS An epidemiological prediction model using data from national cancer registries, observational studies, and clinical trials was developed. Assuming 80% population-level uptake of adjuvant treatment, KATHERINE data were extrapolated prospectively to model projections. Robustness was evaluated in alternative scenarios. RESULTS We projected an eligible population of 116,335 women in Canada and the EU5 who may be diagnosed with HER2-positive eBC and have residual disease following neoadjuvant therapy from 2021-2030. In EU5, the cumulative number of women projected to experience relapsed mBC over the 10-year study period was 36,009 vs 27,143 under adjuvant trastuzumab vs T-DM1, a difference of 8,866 women, equivalent to 25% fewer cases with the use of adjuvant T-DM1 in EU5 countries from 2021-2030. Findings were similar for Canada. CONCLUSION Our models predicted greater reductions in the occurrence of relapsed mBC with adjuvant T-DM1 vs trastuzumab in the indicated populations in EU5 and Canada. Introduction of T-DM1 has the potential to reduce population-level disease burden of HER2-positive mBC in the geographies studied.

Abstract
PURPOSE Data from randomized controlled trials in high-grade endometrial cancer are scarce due to its low prevalence. Therefore, guideline recommendations in this cancer subtype rely on relatively few randomized trials and data from retrospective studies. The aim of this study was to evaluate the benefits from guideline-concordant therapy in high-grade endometrial cancer in a real-world patient group. METHODS The effect of treatment according to German S3 guidelines and the former S2k guideline on overall survival (OS) and recurrence-free survival (RFS) was evaluated in a cohort of 293 high-grade endometrial cancer patients. RESULTS Treatment concordant with the S3 guideline significantly improved OS (HR 0.623, CI 0.420-0.923, p = 0.018) and RFS (HR 0.578, CI 0.387-0.863, p = 0.007). Treatment concordant with the S2k guideline did not result in a significantly higher OS (HR 0.783, CI 0.465-1.316, p = 0.335) or RFS (HR 0.741, CI 0.347-1.740, p = 0.242). CONCLUSION Therapy according to the German S3 guideline improved OS and RFS in univariate as well as multivariate analysis in this cohort of high-grade endometrial cancer patients.

The association between guideline adherence, age and overall survival among women with non-metastatic breast cancer: A systematic review. Cancer Treat Rev 2022; 104:102353. [PMID: 35152157 DOI: 10.1016/j.ctrv.2022.102353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 01/22/2022] [Accepted: 01/25/2022] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Conformity with treatment guidelines should benefit patients. Studies have reported variation in adherence to breast cancer (BC) guidelines, particularly among older women. This study investigated (i) whether adherence to treatment guideline recommendations for women with non-metastatic BC improves overall survival (OS), (ii) whether that relationship varies by age. METHODOLOGY MEDLINE and EMBASE were systematically searched for studies on guideline adherence and OS in women with non-metastatic BC, published after January 2000, which examined recommendations on breast surgery, chemotherapy, radiotherapy or endocrine therapy. Study results were summarised using narrative synthesis. RESULTS Sixteen studies met the inclusion criteria. The recommendations for each treatment covered were similar, but studies differed in their definitions of adherence. 5-year OS rates among patients having compliant treatment ranged from 91.3% to 93.2%, while rates among patients having non-compliant treatment ranged from 75.9% to 83.4%. Six studies reported an adjusted hazard ratio (aHR) for non-compliant treatment compared with compliant treatment; all concluded OS was worse among patients whose overall treatment was non-compliant (aHR range: 1.52 [1.30-1.82] to 2.57 [1.96-3.37]), but adjustment for potential confounders was limited. Worse adherence among older women was reported in 12/16 studies, but they did not provide consistent evidence on whether OS was associated with treatment adherence and age. CONCLUSIONS Individual studies reported that better adherence to guidelines improved OS among women with non-metastatic BC, but the evidence base has weaknesses including inconsistent definitions of adherence. More precise and consistent research designs, including the evaluation of barriers to adherence across the spectrum of healthcare practice, are required to fully understand guideline compliance, as well as the relationship between compliance and OS following a BC diagnosis.

Receipt of Guideline-Concordant Care Does Not Explain Breast Cancer Mortality Disparities by Race in Metropolitan Atlanta. J Natl Compr Canc Netw 2021; 19:1242-1251. [PMID: 34399407 PMCID: PMC8847540 DOI: 10.6004/jnccn.2020.7694] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 12/02/2020] [Indexed: 01/25/2023]
Abstract
BACKGROUND Racial disparities in breast cancer mortality in the United States are well documented. Non-Hispanic Black (NHB) women are more likely to die of their disease than their non-Hispanic White (NHW) counterparts. The disparity is most pronounced among women diagnosed with prognostically favorable tumors, which may result in part from variations in their receipt of guideline care. In this study, we sought to estimate the effect of guideline-concordant care (GCC) on prognosis, and to evaluate whether receipt of GCC modified racial disparities in breast cancer mortality. PATIENTS AND METHODS Using the Georgia Cancer Registry, we identified 2,784 NHB and 4,262 NHW women diagnosed with a stage I-III first primary breast cancer in the metropolitan Atlanta area, Georgia, between 2010 and 2014. Women were included if they received surgery and information on their breast tumor characteristics was available; all others were excluded. Receipt of recommended therapies (chemotherapy, radiotherapy, endocrine therapy, and anti-HER2 therapy) as indicated was considered GCC. We used Cox proportional hazards models to estimate the impact of receiving GCC on breast cancer mortality overall and by race, with multivariable adjusted hazard ratios (HRs). RESULTS We found that NHB and NHW women were almost equally likely to receive GCC (65% vs 63%, respectively). Failure to receive GCC was associated with an increase in the hazard of breast cancer mortality (HR, 1.74; 95% CI, 1.37-2.20). However, racial disparities in breast cancer mortality persisted despite whether GCC was received (HRGCC: 2.17 [95% CI, 1.61-2.92]; HRnon-GCC: 1.81 [95% CI, 1.28-2.91] ). CONCLUSIONS Although receipt of GCC is important for breast cancer outcomes, racial disparities in breast cancer mortality did not diminish with receipt of GCC; differences in mortality between Black and White patients persisted across the strata of GCC.

Abstract
Objective To identify comorbidity indices that have been validated in cancer populations, with a focus on breast cancer and human epidermal growth factor receptor-2-positive (HER2+) breast cancer. Study design and setting A systematic review of the literature on the use of comorbidity indices in any cancer, breast cancer, and HER2+ breast cancer using Ovid and PubMed. Results The final data set comprised 252 articles (252 any cancer, 39 breast cancer, 7 HER2+ breast cancer). The most common cancers assessed were hematologic and breast, and the most common comorbidity index used was the Charlson Comorbidity Index (CCI) or a CCI derivative. Most validity testing of comorbidity indices used predictive validity based on survival outcomes. Hazard ratios for survival outcomes generally found that a higher comorbidity burden (measured by CCI) increased mortality risk in patients with breast cancer. All breast-cancer studies that validated comorbidity indices used CCI-based indices. Only one article validated a comorbidity index in HER2+ breast cancer. Conclusion CCI-based indices are the most appropriate indices to use in the general breast-cancer population. There is insufficient validation of any comorbidity index in HER2+ breast cancer to provide a recommendation, indicating a future need to validate these instruments in this population.

Abstract
PURPOSE Since 2008, guidelines recommend that patients with HER2-positive early breast cancer (BC) should receive adjuvant chemotherapy in combination with trastuzumab in Germany. However, recent studies highlight that a substantial share of patients do not receive trastuzumab. We investigate which patient characteristics are associated with a tumor board recommendation for trastuzumab in Breast Cancer Centers (BCC) certified by the German Cancer Society (DKG) and the German Society for Senology, and if the recommendation differs between BCCs. MATERIALS AND METHODS Multi-level modeling was performed using quality assurance data based on 3052 HER2-positive, operated patients with a first diagnosis of early BC treated between 2006 and 2019 in 17 BCCs in Germany to investigate whether trastuzumab recommendation varies with patient sex, age, and disease characteristics, as well as over time and across BCCs. RESULTS Tumor board recommendations for trastuzumab differ substantially between BCCs (intraclass correlation coefficient [ICC] null model: 0.11). Our final model (ICC 0.17, Akaike Information Criterion [AIC], 1328.0, R2 0.69) shows that physicians in BCCs more often recommend trastuzumab to patients who are younger than 60 years and those with a recommendation for any additional therapy (chemotherapy, radiation or endocrine therapy) (all p < 0.05). Furthermore, there is a significant time-dependent increase of trastuzumab recommendations (odds ratio [OR] = 1.38, 95% confidence interval [CI] = 1.31-1.46, p < 0.05). CONCLUSION In certified BCCs in Germany, guideline concordant trastuzumab recommendation is increasing since 2006 (positive cohort effect). Recommendation of trastuzumab for HER2-positive BC patients in BCCs is significantly associated with patients' age and the recommendations for other additional therapy strategies, apart from surgery. The quality assurance data analyzed do not include potentially relevant confounders, such as socioeconomic status or comorbidities.

Abstract
Childhood cancer survivors are at significant risk for late cancer treatment-related morbidity and mortality. Physicians involved in the care of childhood cancer survivors should be aware of these specific health problems and provide high-quality, long-term follow-up care to preserve and improve survivors' health. The steps required to achieve high-quality care include synthesizing evidence (systematic reviews are helpful in this regard), developing clinical policy from evidence into evidence-based clinical practice guidelines, disseminating and implementing clinical practice guidelines, and evaluating their impact on quality of care and survivor health outcomes with quality indicators. This article describes these cornerstones of evidence-based medicine.

Abstract
Health services research in oncology deals with all situations which cancer patients face. It looks at the different phases of care, i. e. prevention / early detection, prehabilitation, diagnostics, therapy, rehabilitation and palliative care as well as the various actors, including those affected, the carers and self-help. It deals with healthy people (e. g. in the context of prevention / early detection), patients and cancer survivors. Due to the nature of cancer and the existing care structures, there are a number of specific contents for health services research in oncology compared to general health services research while the methods remain essentially identical. This memorandum describes the subject, illustrates the care structures and identifies areas of health services research in oncology. This memorandum has been prepared by the Oncology Section of the German Network for Health Services Research and is the result of intensive discussions.

Abstract
Objective To assess the long-term effectiveness and safety of trastuzumab in adjuvant therapy for Chinese patients with early-stage human epidermal growth factor 2 (HER2)-positive breast cancer in a real-world setting. Methods This retrospective observational study analyzed the medical records of HER2-positive breast cancer patients between 2000 and 2012 at the Chinese Academy of Medical Sciences. Patients who received adjuvant chemotherapy alone or adjuvant chemotherapy followed by/combined with trastuzumab were included. The Kaplan-Meier method was used to estimate disease-free survival (DFS) and overall survival (OS). Hazard ratios (HR) and 95% confidence intervals (95% CI) were calculated using the Cox regression model. Results Of the 1,348 patients analyzed, 909 received chemotherapy alone and 439 received chemotherapy plus trastuzumab. The 3-year, 5-year and 10-year DFS rates were 83.70%, 76.38% and 68.94%, respectively, in the chemotherapy-alone cohort, and 90.21%, 86.19% and 83.45% in the chemotherapy plus trastuzumab cohort. The 3-year, 5-year and 10-year OS rates were 96.10%, 91.40% and 81.88% in the chemotherapy-alone cohort, and 98.17%, 94.91% and 90.01% in the chemotherapy plus trastuzumab cohort. The chemotherapy plus trastuzumab group had a significantly lower risk of disease recurrence and death than the chemotherapy-alone group (DFS: HR=0.50, 95% CI, 0.37-0.68; P<0.001; OS: HR=0.53, 95% CI, 0.34-0.81; P=0.004) after adjusting for covariates. In the 439 patients treated with trastuzumab, multivariate analysis suggested that lymph node positivity, higher T stages, and hormone receptor-negative status were significantly associated with higher risks of disease recurrence, and lymph node positivity and hormone receptor-negative status were significantly associated with higher risks of death. Grade 3/4 adverse events (incidence ≥1%) were more common in patients receiving trastuzumab (54.44%vs. 15.73%). Conclusions Early-stage HER2-positive breast cancer patients treated with trastuzumab plus adjuvant chemotherapy have a significant survival benefit compared with chemotherapy-alone in real-world settings. Lymph node positivity, hormone receptor-negative status, and higher T stages may be associated with higher risks of recurrence, and effective therapy for patients with these factors is required.

Economic modeling of risk-adapted screen-and-treat strategies in women at high risk for breast or ovarian cancer. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2019; 20:739-750. [PMID: 30790097 DOI: 10.1007/s10198-019-01038-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2018] [Accepted: 02/12/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND The 'German Consortium for Hereditary Breast and Ovarian Cancer' (GC-HBOC) offers women with a family history of breast and ovarian cancer genetic counseling. The aim of this modeling study was to evaluate the cost-effectiveness of genetic testing for BRCA 1/2 in women with a high familial risk followed by different preventive interventions (intensified surveillance, risk-reducing bilateral mastectomy, risk-reducing bilateral salpingo-oophorectomy, or both mastectomy and salpingo-oophorectomy) compared to no genetic test. METHODS A Markov model with a lifelong time horizon was developed for a cohort of 35-year-old women with a BRCA 1/2 mutation probability of ≥ 10%. The perspective of the German statutory health insurance (SHI) was adopted. The model included the health states 'well' (women with increased risk), 'breast cancer without metastases', 'breast cancer with metastases', 'ovarian cancer', 'death', and two post (non-metastatic) breast or ovarian cancer states. Outcomes were costs, quality of life years gained (QALYs) and life years gained (LYG). Important data used for the model were obtained from 4380 women enrolled in the GC-HBOC. RESULTS Compared with the no test strategy, genetic testing with subsequent surgical and non-surgical treatment options provided to women with deleterious BRCA 1 or 2 mutations resulted in additional costs of €7256 and additional QALYs of 0,43 (incremental cost-effectiveness ratio of €17,027 per QALY; cost per LYG: €22,318). The results were robust in deterministic and probabilistic sensitivity analyses. CONCLUSION The provision of genetic testing to high-risk women with a BRCA1 and two mutation probability of ≥ 10% based on the individual family cancer history appears to be a cost-effective option for the SHI.

Relationship between Clinicopathologic Variables in Breast Cancer Overall Survival Using Biogeography-Based Optimization Algorithm. BIOMED RESEARCH INTERNATIONAL 2019; 2019:2304128. [PMID: 31058185 PMCID: PMC6463600 DOI: 10.1155/2019/2304128] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/28/2018] [Revised: 02/27/2019] [Accepted: 02/28/2019] [Indexed: 12/02/2022]
Abstract
Breast cancer is the most common cancer among women and is considered a major public health concern worldwide. Biogeography-based optimization (BBO) is a novel metaheuristic algorithm. This study analyzed the relationship between the clinicopathologic variables of breast cancer using Cox proportional hazard (PH) regression on the basis of the BBO algorithm. The dataset is prospectively maintained by the Division of Breast Surgery at Kaohsiung Medical University Hospital. A total of 1896 patients with breast cancer were included and tracked from 2005 to 2017. Fifteen general breast cancer clinicopathologic variables were collected. We used the BBO algorithm to select the clinicopathologic variables that could potentially contribute to predicting breast cancer prognosis. Subsequently, Cox PH regression analysis was used to demonstrate the association between overall survival and the selected clinicopathologic variables. C-statistics were used to test predictive accuracy and the concordance of various survival models. The BBO-selected clinicopathologic variables model obtained the highest C-statistic value (80%) for predicting the overall survival of patients with breast cancer. The selected clinicopathologic variables included tumor size (hazard ratio [HR] 2.372, p = 0.006), lymph node metastasis (HR 1.301, p = 0.038), lymphovascular invasion (HR 1.606, p = 0.096), perineural invasion (HR 1.546, p = 0.168), dermal invasion (HR 1.548, p = 0.028), total mastectomy (HR 1.633, p = 0.092), without hormone therapy (HR 2.178, p = 0.003), and without chemotherapy (HR 1.234, p = 0.491). This number was the minimum number of discriminators required for optimal discrimination in the breast cancer overall survival model with acceptable prediction ability. Therefore, on the basis of the clinicopathologic variables, the survival prediction model in this study could contribute to breast cancer follow-up and management.

Abstract
PURPOSE In 2003, a certification system was introduced to ensure high standards of oncological care in breast cancer patients in Germany. Certified breast cancer centers (BCCs) must fulfill specific requirements including quality indicators (QI) derived from the clinical guidelines that are evaluated in annual audits. When target values for QIs are not fulfilled, centers need to give explanations. We analyzed data from BCCs for a selected indicator: the recommendation of trastuzumab for patients with early HER-2-positive invasive breast cancer. We investigated explanations given in cases when trastuzumab was not recommended to see whether this was justified. METHODS Patient data from 274 BCCs treating 53,777 primary cases in 2015 were analyzed using descriptive statistics. RESULTS In the 274 BCC sites, 5700 primary patients with early HER-2-positive breast cancer were treated in 2015. 128 sites (46.7%) did not reach the target value of 95% trastuzumab recommendation and thus had to give explanations. In these 128 sites, 2663 primary HER-2-positive breast cancer patients were treated, 343 (12.9%) of whom did not receive a recommendation for adjuvant trastuzumab treatment. All 128 sites delivered explanations. Overall, 450 explanations were given, allowing multiple explanations for single patients. No explanation was given for 8 of the 343 patients (2.3%). The most common given explanation was multi-/comorbidity (45.5%). CONCLUSIONS The analysis suggests thorough decision-making when quality indicator target values for a trastuzumab recommendation were not fulfilled. Our data do not provide information on whether such decisions have an impact on treatment outcome for these patients.

Abstract
PURPOSE To assess and explain variation in quality of care in breast cancer patients and estimate its impact on disease outcome. METHODS The Slovenian National Cancer Registry database and clinical records of 1053 women with unilateral primarily non-metastatic invasive breast cancer diagnosed in 2013 were reviewed in this retrospective analysis. Quality care was defined as care fully compliant with quality indicators (QI) defined by European Society of Breast Cancer Specialists (EUSOMA). Multivariate logistic regression was used to determine the predictors of receiving quality care. Differences in overall survival (OS) and event-free survival (EFS, relapse, or progression of disease or death considered an event) based on adherence to QI were analyzed using Kaplan-Meier method and Cox models. RESULTS Younger age, no comorbidities, and HER2-negative tumor were associated with increased odds ratios for receiving quality care, whereas tumor stage and type of hospital had no significant association. Median follow-up was 54.5 months. Not receiving quality care resulted in an increased risk of dying [hazard ratio (HR) 1.68; 95% confidence interval (CI) 1.06-2.66; p = 0.026]. Difference in EFS between two groups was significant after adjusting for case mix and type of hospital (HR 1.80; 95% CI 1.29-2.52; p = 0.001) but disappeared when type of treatment was added into the model (HR 1.30; 95% CI 0.89-1.90; p = 0.178). CONCLUSION Observed comorbidity and age bias in delivering quality breast cancer care could be medically justifiable, whereas observed deviations dependent on HER2 status are puzzling. Complete adherence of treatment to quality indicators resulted in better OS.

Abstract
Providing evidence-based supportive care for children with cancer has the potential to optimize treatment outcomes and improve quality of life. The Children's Oncology Group (COG) Supportive Care Guidelines Subcommittee conducted a systematic review to identify current supportive care clinical practice guidelines (CPGs) relevant to childhood cancer or pediatric hematopoietic stem cell transplant. Only 22 papers met the 2011 Institute of Medicine criteria to be considered a CPG. The results highlight the paucity of CPGs available to pediatric oncology healthcare professionals and the pressing need to create CPGs using current methodological standards.

Abstract
BACKGROUND Women with a BRCA1 or BRCA2 mutation are at increased risk of developing breast and/or ovarian cancer. This economic modeling study evaluated different preventive interventions for 30-year-old women with a confirmed BRCA (1 or 2) mutation. METHODS A Markov model was developed to estimate the costs and benefits [i.e., quality-adjusted life years (QALYs), and life years gained (LYG)] associated with prophylactic bilateral mastectomy (BM), prophylactic bilateral salpingo-oophorectomy (BSO), BM plus BSO, BM plus BSO at age 40, and intensified surveillance. Relevant input data was obtained from a large German database including 5902 women with BRCA 1 or 2, and from the literature. The analysis was performed from the German Statutory Health Insurance (SHI) perspective. In order to assess the robustness of the results, deterministic and probabilistic sensitivity analyses were performed. RESULTS With costs of €29,434 and a gain in QALYs of 17.7 (LYG 19.9), BM plus BSO at age 30 was less expensive and more effective than the other strategies, followed by BM plus BSO at age 40. Women who were offered the surveillance strategy had the highest costs at the lowest gain in QALYs/LYS. In the probabilistic sensitivity analysis, the probability of cost-saving was 57% for BM plus BSO. At a WTP of 10,000 € per QALY, the probability of the intervention being cost-effective was 80%. CONCLUSIONS From the SHI perspective, undergoing BM plus immediate BSO should be recommended to BRCA 1 or 2 mutation carriers due to its favorable comparative cost-effectiveness.

Abstract
BACKGROUND Several regimens for which efficacy was established in randomized controlled trials are recommended in current treatment guidelines for early breast cancer. However, knowledge on use and effectiveness of commonly administered chemotherapeutic agents in real-life care and across all breast cancer subtypes is limited. METHODS The prospective, multicentre German TMK cohort study (Tumour Registry Breast Cancer) recruited patients in 148 oncology outpatient-centres. Data from 1650 patients who completed adjuvant chemotherapy were analysed regarding treatment regimens and taxane use from 2007 to 2014. The association of patient characteristics with application of taxane-free regimens was examined with a multivariate regression model. RESULTS The preferred adjuvant treatment shifted from fluorouracil, anthracycline and cyclophosphamide containing regimens to anthracycline/taxane combinations. Taxane use increased for all subtypes, and the greatest rise was among node-negative patients. Older age, node-negativity, lower grading, HR-positive/HER2-negative subtype and earlier start year of therapy were significantly associated with taxane-free therapy. CONCLUSIONS Treatment with anthracycline/taxane-based chemotherapy in Germany has been rising for every subtype. The increased taxane use reflects updated guideline recommendations over the past decade. Cohort studies like the TMK provide insight into real-life treatment of patients outside of clinical trials.

Abstract
BACKGROUND Current evidence-based guideline-concordant care (GCC) for locally advanced non-small-cell lung cancer (NSCLC) patients with good performance status is concurrent chemoradiation. In this study we evaluated factors associated with lack of GCC and its effects on overall survival (OS). PATIENTS AND METHODS Unresectable stage III NSCLC patients, diagnosed from 2005 to 2013 with a Charlson-Deyo score of 0, were identified from the National Cancer Database. Primary outcomes were receipt of GCC, defined as concurrent chemoradiation (thoracic radiotherapy, starting within 2 weeks of chemotherapy, to at least 60 Gy), and OS. Multivariable logistic regression modeling identified variables associated with non-GCC. Cox proportional hazard modeling was used to examine OS. RESULTS Twenty-three percent of patients (n = 10,476) received GCC. Uninsured patients were more likely to receive non-GCC (odds ratio [OR], 1.54; P < .001) compared with privately insured patients. Other groups with greater odds of receiving non-GCC included: patients treated in the western, southern, or northeastern United States (ORs, 1.39, 1.37, and 1.19, respectively; all Ps < .001) compared with the Midwest; adenocarcinoma histology (OR, 1.48; P < .001) compared with squamous cell carcinoma; and women (OR, 1.08; P = .002). Those who received non-GCC had higher death rates compared with those who received GCC (hazard ratio [HR], 1.42; P < .001). The uninsured (HR, 1.53; P < .001), patients treated in the western, southern, or northeastern United States (HRs, 1.56, 1.41, and 1.34, respectively; P < .001), adenocarcinomas (HR, 1.39; P < .001), and women (HR, 1.44; P < .001) also all had lower OS for non-GCC versus GCC. CONCLUSION Socioeconomic factors, including lack of insurance and geography, are associated with non-GCC. Patient- and disease-specific factors, including increasing adenocarcinoma histology and sex, are also associated with non-GCC. Non-GCC diminishes OS.

Screening-relevant age threshold of 70 years and older is a stronger determinant for the choice of adjuvant treatment in breast cancer patients than tumor biology. Breast Cancer Res Treat 2017; 163:119-130. [PMID: 28205042 PMCID: PMC5387012 DOI: 10.1007/s10549-017-4151-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2016] [Accepted: 02/07/2017] [Indexed: 12/21/2022]
Abstract
Purpose The 70-year threshold determines whether patients are eligible or not for the breast cancer screening program in Germany. It is not known whether this age threshold also influences the choice of adjuvant treatment and ultimate outcome. Methods 3463 patients were analyzed from the clinical cancer registry Regensburg (Germany) with primary, non-metastatic invasive breast cancer diagnosed between 2000 and 2012. The distribution of tumor biological subtypes was evaluated in breast cancer patients both in those eligible for screening (ESG, 50–69 years) and those not eligible for screening (NESG, ≥70 years). Local and systemic therapies in different subtypes as well as overall survival (OS) were analyzed. Results 2171 patients (62.7%) pertained to the ESG and 1292 patients (37.3%) referred to the NESG. The distribution of the common subtypes Luminal A, Luminal B, HER2-like, and Basal-like was comparable in both groups. Treatment varied considerably with less systemic therapies in all subtypes in patients in the NESG. Regarding local therapies, patients in the NESG also received less surgery and less radiotherapy. As to Luminal A patients, best OS was seen in patients receiving endocrine therapy (ET) (7-year OS of 95.6%) and CHT plus ET (7-year OS of 93.1%) in the ESG. In the NESG, best OS was seen in patients receiving CHT plus ET (7-year OS of 95.2%), whereas patients receiving only ET had a 7-year OS of 73.9%. Conclusions Despite similar tumor biology, elderly patients are undertreated regarding both systemic and local therapies compared to younger patients, leading to reduced OS.

Abstract
As cure rates in pediatric oncology have improved substantially over the last decades, supportive care has become increasingly important to reduce morbidity and mortality and improve quality of life in children with cancer. Currently, large variations exist in pediatric oncology supportive care practice, which might negatively influence care. This plea underlines the importance of development and implementation of trustworthy supportive care clinical practice guidelines, which we believe is the essential next step towards better supportive care practice, and thus a higher quality of care. To facilitate international development and endorsement, the International Pediatric Oncology Guidelines in Supportive Care Network has been established.

Breast Cancer Res Treat 2016; 157:145-56. [PMID: 27107569 PMCID: PMC4869764 DOI: 10.1007/s10549-016-3790-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2016] [Accepted: 04/05/2016] [Indexed: 01/03/2023]
Abstract
Trastuzumab reduces the risk of relapse in women with HER2-positive non-metastatic breast cancer, but little information exists on the timing of trastuzumab initiation. The study investigated the impact of delaying the initiation of adjuvant trastuzumab therapy for >6 months after the breast cancer diagnosis on time to relapse, overall survival (OS), and relapse-free survival (RFS) among patients with non-metastatic breast cancer. Adult women with non-metastatic breast cancer who initiated trastuzumab adjuvant therapy without receiving any neoadjuvant therapy were selected from the US Department of Defense health claims database from 01/2003 to 12/2012. Two study cohorts were defined based on the time from breast cancer diagnosis to trastuzumab initiation: >6 months and ≤6 months. The impact of delaying trastuzumab initiation on time to relapse, OS, and RFS was estimated using Cox regression models adjusted for potential confounders. Of 2749 women in the study sample, 79.9 % initiated adjuvant trastuzumab within ≤6 months of diagnosis and 20.1 % initiated adjuvant trastuzumab >6 months after diagnosis. After adjusting for confounders, patients who initiated trastuzumab >6 months after the breast cancer diagnosis had a higher risk of relapse, death, or relapse/death than those who initiated trastuzumab within ≤6 months of diagnosis (hazard ratios [95 % CIs]: 1.51 [1.22-1.87], 1.54 [1.12-2.12], and 1.43 [1.16-1.75]; respectively). The results of this population-based study suggest that delays of >6 months in the initiation of trastuzumab among HER2-positive non-metastatic breast cancer patients are associated with a higher risk of relapse and shorter OS and RFS.

Abstract
INTRODUCTION Breast cancer can be divided into four subtypes based on the expressions of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor-2 (HER2). Each subtype has different clinicopathological features and outcomes. OBJECTIVE To compare the clinicopathological features and survival of ER and/or PR positive HER2 negative (ER+PR+HER2-, ER+PR-HER2- or ER-PR+HER2-), ER and/or PR positive HER2 positive (ER+PR+HER2+, ER+PR-HER2+ or ER-PR+HER2+), ER negative PR negative HER2 positive (ER-PR-HER2+), and ER negative PR negative HER2 negative (ER-PR-HER2-) subtypes. METHODS 1957 patients with Stage 1-3 breast carcinoma diagnosed between Jan 2005 and Dec 2011 were categorized into the four subtypes. The clinicopathological features between the subtypes were compared using χ (2) test. Kaplan-Meier analysis was performed to estimate 5-year overall survival. Multivariate Cox regression was used to determine the association between subtypes and mortality adjusted for age, ethnicity, stage, pathological features, and treatment. RESULTS ER-PR-HER2+ and ER-PR-HER2- subtypes were associated with younger age, larger tumors, and higher grade. There was no difference in the 5-year survival of the ER-PR-HER2+ and ER-PR-HER2- subtypes (75.1 and 74.4 %, respectively) and survival was poorer than in the ER and/or PR positive HER2 negative and ER and/or PR positive HER2 positive subtypes (87.1 and 83.1 %, respectively). Only 9.5 % of women with HER2 positive breast cancer had access to trastuzumab. CONCLUSION In a low resource setting with limited access to trastuzumab, there is no difference in survival between the ER-PR-HER2+ and ER-PR-HER2- subtypes of breast cancer.

Abstract
PURPOSE The NSABP Trial B-31 and NCCTG Trial N9831 (B-31/N9831 trials, Romond et al. in N Engl J Med 353:1673-84, 2005. doi:10.1056/NEJMoa052122; Perez et al. in J Clin Oncol 32:3744-52, 2014. doi:10.1200/JCO.2014.55.5730) established the efficacy of adjuvant trastuzumab for patients with HER2-positive early stage breast cancer. We aimed to estimate the overall survival (OS) and relapse-free survival (RFS) of HER2-positive non-metastatic breast cancer patients treated with adjuvant trastuzumab in a clinical practice setting in the United States. METHODS Adult women initiating adjuvant trastuzumab within 1 year of breast cancer surgery were identified in the health claims database of the US Department of Defense (01/2003-12/2012). OS and RFS unadjusted rates at 4 and 6 years after the first trastuzumab treatment following the breast cancer diagnosis were estimated from Kaplan-Meier analyses. RESULTS The study sample included 3188 women followed for a median of 3.3 years after trastuzumab initiation and treated continuously with trastuzumab for a median of 12 months. The OS rates (95 % confidence intervals) at 4 and 6 years were 90.0 % (88.6-91.2) and 87.1 (85.3-88.6), respectively. The corresponding RFS rates were 75.8 % (74.0-77.5) and 72.7 (70.7-74.7), respectively. The OS and RFS rates at 6 years reported in the B-31/N9831 trials were 89.8 and 81.4 %, respectively. CONCLUSIONS OS rates estimated in this study were in range with those estimated in the B-31/N9831 trials, while RFS rates were lower. However, patients in the B-31/N9831 trials were younger and possibly had fewer comorbidities than patients in the current study; these differences were not adjusted for in the crude OS and RFS analyses.

Pathological complete response and prognosis after neoadjuvant chemotherapy for HER2-positive breast cancers before and after trastuzumab era: results from a real-life cohort. Br J Cancer 2015; 114:44-52. [PMID: 26657653 PMCID: PMC4716543 DOI: 10.1038/bjc.2015.426] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Revised: 11/02/2015] [Accepted: 11/10/2015] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Trastuzumab was introduced a decade ago and has improved outcomes for HER2-positive breast cancer. We investigated the factors predictive of pathological complete response (pCR), prognostic factors for disease-free survival (DFS), and interactions between pCR and DFS after neoadjuvant treatment. METHODS We identified 287 patients with primary HER2-positive breast cancers given neoadjuvant chemotherapy (NAC) between 2002 and 2011. Univariate and multivariate analyses of clinical and pathological factors associated with pCR and DFS were performed. RESULTS pCR rates differed between patients receiving neoadjuvant trastuzumab treatment or not (47.7% versus 19.3%, P<0.0001). DFS also differed significantly between patients receiving adjuvant trastuzumab or not (hazard ratio=4.84, 95% CI (2.52; 9.31), P<0.001). We analysed 199 patients given neoadjuvant and adjuvant trastuzumab. Multivariate analysis identified older age and hormone receptor-negative tumours as independent predictors of pCR. T stage (hazard ratio=2.55, 95% CI (1.01; 6.48), P=0.05) and strict pCR (hazard ratio=9.15, 95% CI (1.22; 68.83), P=0.03) were independent predictors of DFS. The latter association was significant in the HR-negative subgroup (P=0.02) but not in the HR-positive subgroup (P=0.12). CONCLUSIONS Major pCR and DFS gains in HER2-positive BC were observed since 'trastuzumab' era. Further improvements rely on the enrollment of accurately selected patients into clinical trials.

4-IHC classification of breast cancer subtypes in a large cohort of a clinical cancer registry: use in clinical routine for therapeutic decisions and its effect on survival. Breast Cancer Res Treat 2015; 153:647-58. [PMID: 26369534 PMCID: PMC4589562 DOI: 10.1007/s10549-015-3572-3] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2015] [Accepted: 09/07/2015] [Indexed: 01/28/2023]
Abstract
The aim of the present study was to evaluate to what extent the combination of standard histopathological parameters determines the biology of breast cancer and the effect on therapy and prognosis. The Clinical Cancer Registry Regensburg (Bavaria, Germany) included n = 4,480 female patients with primary, non-metastatic (M0) invasive breast cancer diagnosed between 2000 and 2012. Immuno-histochemical analyses, i.e., estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki-67 (4-IHC), defined the tumor biological subtypes Luminal A, Luminal B, HER2-like, and Basal-like. Subtype-related differences in therapies and overall survival (OS) were analyzed using multivariable statistical methods. 4344 patients (97.0 %) could be classified into the four common tumor biological subtypes. The two most frequent entities were Luminal A (48.4 %), Luminal B (24.8 %), HER2-like (17.8 %), and Basal-like subtype (9.0 %). A multivariable Cox regression model showed that the best 7-year OS was seen in Luminal A patients and that OS of Luminal B and HER2-like patients was comparable (HR = 1.59, P < 0.001 versus HR = 1.51, P = 0.03). Lowest OS was seen in patients with Basal-like tumors (HR = 2.18, P < 0.001). In conclusion, the classification of tumor biological subtypes by the ER, PR, HER2, and Ki-67 biomarkers is practical in routine clinical work. Providing that quality assurance of these markers is ensured, this classification is useful for making therapy decisions in the routine clinical management of breast cancer patients.

Abstract
PURPOSE Adjuvant endocrine therapy (ET) is indicated in patients with steroid hormone receptor (HR)-positive breast cancer. The aim of this study was to evaluate the quality of HR determination and adjuvant endocrine treatment of breast cancer patients in a large cohort of more than 7000 women by analyzing data from a population-based regional cancer registry. METHODS Data from the Clinical Cancer Registry Regensburg (Bavaria, Germany) were analyzed. Female patients with primary, nonmetastatic invasive breast cancer who were diagnosed between 2000 and 2012 (n = 7421) were included. HR-status was available in 97.4 % (n = 7229) of the patients. This data set (n = 7229) was used for subsequent statistical analyses. RESULTS Since 2009, almost a complete rate of 99.6 % of analyzed HR-status was achieved. In sum, 85.8 % of the patients (n = 6199) were HR-positive, whereas 14.2 % (n = 1030) were HR-negative. Overall, 85.3 % (n = 5285) of HR-positive patients received ET either alone or in combination with chemotherapy (CHT) and/or trastuzumab. The majority of premenopausal patients received CHT plus ET (716 patients, 52.3 %). In postmenopausal patients, the most frequent systemic therapy was ET alone (2670 patients, 55.3 %). Best overall survival (OS) was found in HER2-/HR-positive patients receiving CHT plus ET plus trastuzumab (7-year OS rate of 97.2 % in premenopausal patients versus 86.9 % in postmenopausal patients). Premenopausal patients had a reduced benefit from additional CHT than postmenopausal patients. Premenopausal patients receiving only ET had a 7-year OS rate of 95.3 % compared to 92.7 % of patients receiving CHT plus ET. In contrast, postmenopausal patients treated with CHT plus ET had a 7-year OS rate of 84.0 % in comparison with those patients receiving only ET with a 7-year OS rate of 81.7 %. CONCLUSIONS Analysis of HR in patients with early breast cancer achieved a very high quality in recent years. The vast majority of HR-positive patients received ET, and this guideline-adherent use improved OS. Inverse effects of the CHT plus ET combination in premenopausal versus postmenopausal patients and a still existing minority of patients not receiving guideline-adherent treatment should be further investigated in future studies.

Abstract
PURPOSE Febrile neutropenia (FN) after chemotherapy increases complications, morbidity, risk of death, reduction of dose delivery and impairs quality of life. Primary granulocyte-colony stimulating factor (G-CSF) prophylaxis after chemotherapy is recommended in the guideline (GL) if the risk of FN is high (≥20%) or intermediate (≥10-20%) with additional risk factors. This study evaluated the implementation of G-CSF GL. PATIENTS AND METHODS Sample size of the survey was calculated at 2% of the incidences of malignant lymphoma, breast cancer, and lung cancer in Germany in 2006. Patients were documented retrospectively over three to nine cycles of chemotherapy and FN risk ≥10%. Professional physician profiles were analyzed by classification and regression tree analysis (CART). RESULTS One hundred ninety-five hematologists-oncologists and pulmonologists and gynecologists specialized in oncology documented data of 666 lung cancer patients, 286 malignant lymphoma patients, and 976 breast cancer patients, with 7805 chemotherapy cycles; 85.1% of physicians claimed adhering to G-CSF GL. Adherence to GL in all high-FN-risk chemotherapy cycles was 15.4% in lung cancer, 84.5% in malignant lymphoma, and 85.6% in breast cancer, and in all intermediate-FN-risk chemotherapy cycles, lung cancer it was 38.8%, malignant lymphoma it was 59.4%, and breast cancer it was 49.3%. G-CSF was overused without additional patient risk factors in 7.2% lung cancer cycles, 16.8% malignant lymphoma cycles, and 17.6% breast cancer cycles. The CART analysis split pulmonologists and other specialists, with the latter adhering more to GL. Pulmonologists, trained less than 22.5 years, adhered better to GL, as did also gynecologists or hematologists-oncologists with professional experience less than 8.1 years. CONCLUSIONS Acceptance of and adherence to G-CSF GL differed between lung cancer, lymphoma, and breast cancer. Physicians overestimate their adherence to the GL. Physicians adhering to the GL can be characterized.

Abstract
Addition of trastuzumab to adjuvant chemotherapy has dramatically reduced the risk of recurrence and has become the standard of care for human epidermal growth factor receptor 2 (HER2)-positive early breast cancer patients. Since most data on trastuzumab benefits come from clinical trials, conducted in selected patient populations, we performed a retrospective analysis of HER2-positive early breast cancer patients treated in the "pre-trastuzumab" and "trastuzumab" eras, with the aim to determine patients' outcomes in real-world practice. 925 consecutive HER2-positive breast cancer patients treated with adjuvant chemotherapy in ten Italian oncologic centers were identified. Patients who had received adjuvant chemotherapy alone (cohort A, 352 patients), and patients who had received adjuvant chemotherapy followed or combined with trastuzumab (cohort B, 573 patients) were analyzed. Relapse rate at 3 years, relapse-free survival, and overall survival were significantly more unfavorable in the cohort A than in the cohort B (p < 0.0001). In multivariate analysis, factors related to relapse were younger age, advanced stage at diagnosis, absence of hormonal and of trastuzumab therapy. The benefit derived from the addition of trastuzumab was independent of nodal status and hormonal receptors expression. A subgroup analysis including 163 "triple positive" tumors with high levels of estrogen and progesterone receptor (TP50) suggested that addition of trastuzumab to adjuvant chemotherapy and hormonal therapy did not translate into better outcomes. In our analysis, trastuzumab benefit was confirmed in all but a small subset of TP50 tumors subgroups. In this subset further investigations are needed.
