Purpose Although new drugs were approved during the 1990s for the treatment of metastatic breast cancer, it is not clear whether their use has changed the outcome of patients in daily practice. This study sought to determine whether survival has improved over time for breast cancer patients who had metastases at diagnosis. Patients and Methods A total of 724 patients have been treated in three French cancer centers for an initially metastatic breast cancer between 1987 and 2000; 343 were diagnosed between 1987 and 1993, and 381 were diagnosed between 1994 and 2000. Tumor characteristics, treatments, and outcomes of these patients were compared by χ2 test, log-rank test, and Cox regression analysis. Results Characteristics were not different between the patients diagnosed from 1987 to 1993 and those diagnosed from 1994 to 2000. Ten percent of patients treated from 1987 to 1994 and 58% of patients treated from 1994 to 2000 have received either a taxane or a new aromatase inhibitor. The 3-year overall survival rates were 27% for patients treated from 1987 to 1993 and 44% for patients treated from 1994 to 2000 (P < .001). The treatment period (1994 to 2000 v 1987 to 1993) was a prognostic factor in multivariate analysis (relative risk, 0.6; P < .001). Conclusion The survival of breast cancer patients presenting with metastases at diagnosis has improved over time. This study strongly suggests that this improvement is related to treatment.

AbstractThe debate about surgical resection of primary tumor (PT) in de novo metastatic breast cancer (MBC) patients persists. We explored this approach’s outcomes in patients included in a retrospective registry, named El Álamo, of breast cancer patients diagnosed in Spain (1990–2001). In this analysis we only included de novo MBC patients, 1415 of whom met the study’s criteria. Descriptive, Kaplan-Meier and Cox regression analyses were carried out. Median age was 63.1 years, 49.2% of patients had single-organ metastasis (skin/soft tissue [16.3%], bone [33.8%], or viscera [48.3%]). PT surgery (S) was performed in 44.5% of the cases. S-group patients were younger, had smaller tumors, higher prevalence of bone and oligometastatic disease, and lower prevalence of visceral involvement. With a median follow-up of 23.3 months, overall survival (OS) was 39.6 versus 22.4 months (HR = 0.59, p < 0.0001) in the S- and non-S groups, respectively. The S-group OS benefit remained statistically and clinically significant regardless of metastatic location, histological type, histological grade, hormone receptor status and tumor size. PT surgery (versus no surgery) was associated with an OS benefit suggesting that loco-regional PT control may be considered in selected MBC patients. Data from randomized controlled trials are of utmost importance to confirm these results.

e12096 Background: Chemotherapy-radiotherapy time intervals (CRTI) in breast cancer vary based on recovery from chemotherapy side effects and preferences of physicians and patients. Our study aimed to determine the association of the time-interval between chemotherapy and radiation with prognosis (recurrence and survival duration) in non-metastatic breast cancer patients (stages I-III). Methods: We included female patients from Karmanos Cancer Center (KCC) database > 21 years, diagnosed with non-metastatic breast cancer from 2005-2015, who underwent surgery, chemotherapy and radiation. CRTI was divided into <24, 24-30 and >30 weeks. Cox regression analysis using age, race, stage, grade, ER/PR status and CRTI variables was done to determine the independent predictors of prognosis. Kaplan-Meier survival curves were used to demonstrate differences in survival time of CRTI groups. Results: We included 553 patients, majority were Caucasian (460 [83.5%]) with a mean age of 57.0 years (SD 11.9). Patients in the >30 weeks CRTI group were more likely to have stage III breast carcinoma when compared to <24 and 24-30 weeks groups (45.0% vs.12.4% vs. 27.8%, p-value <0.001). There were no significant differences in the local and distant recurrence rates among the 3 groups. Patients in <24 weeks CRTI group had a greater mean survival (118.7 vs. 109.2 vs.100.9 months; p-value 0.016) when compared to 24-30 and >30 weeks groups. Only clinical stage (stage 3 vs. 1 HR 3.60; 95% CI 1.89-7.02) and ER/PR status (negative vs. positive HR 1.74; 95% CI 1.02-2.94) were independent predictors of overall survival in multivariate analysis. CRTI was not significantly associated with survival in multivariate analysis (<24 weeks ref, 24-30 weeks HR 1.09; 95% CI 0.59-1.93, >30 weeks HR 1.48; 95% CI 0.82-2.59). However, patients in >30 weeks group were at greater risk of dying when compared to <24 weeks, even after controlling for stage. Conclusions: Our study showed a trend towards a worse outcome in patients with longer chemo-radiation interval, despite controlling for other variables in the multivariate analysis. The conclusions of this single center study need to be verified by further studies with larger sample size.

We aimed to evaluate the co-expression of PD-L1 and epithelial-mesenchymal markers in CTCs from metastatic breast cancer (MBC) patients and to determine if there is any relationship with patients’ outcome after eribulin treatment. Using cytospin preparations of peripheral blood mononuclear cells (PBMCs) from MBC patients treated with eribulin and a combination of immunocytochemistry and immunofluorescence, we quantified PD-L1, keratins and vimentin in single and cluster CTCs on days 1 and 8 of the first-treatment cycle. CTCs (n = 173) were found in 31 out of 38 patients. At baseline, the presence of cluster CTCs (p = 0.048), cluster mesenchymal CTCs (mCTCs) (p = 0.0003) or cluster PD-L1+mCTCs (p = 0.006) was associated with shorter overall survival (OS). In multivariate cox regression analysis, the detection of cluster mCTCs was the only parameter associated with increased risk of death (p = 0.024). On day 8 post-eribulin administration, PD-L1+mCTCs and especially single PD-L1+mCTCs decreased in 75% and 89% of patients, respectively. The detection of single PD-L1+mCTCs after eribulin treatment was correlated with shorter PFS (p = 0.047) and OS (p = 0.020). In conclusion, our study identified for the first time that cluster and single PD-L1+mCTCs subpopulations are of clinical significance in patients with MBC and highlighted the importance of CTC phenotyping during treatment with eribulin.

174 Background: It is generally accepted that patients with breast cancer metastases have poor survival. Metastatic breast cancer patients can be considered a heterogeneous population with a varied clinical course, which underscores the need for accurate prediction of survival based on prognostic factors. The purpose of the present study was to identify factors related to survival in breast cancer patients after diagnosis with metastatic disease. Methods: A total of 557 patients with breast cancer metastasis diagnosis seen at one large urban practice have been followed up between January 1, 1999 and June 30, 2008. Demographic, tumor characteristics, clinical factors as predictors of survival were analyzed using Cox regression model. Results: The median survival length was 40 months (range 1-114 months) with 269 (48.3%) alive and 288 (51.7%) dead. This study demonstrated that hypertension, estrogen receptor (ER) and/or progesterone receptor (PR) status, human epidermal growth factor receptor-2 (HER2) status, number of metastatic sites, and body mass index (BMI) at diagnosis with metastatic breast cancer were the most relevant prognostic factors for survival after metastasis. Conclusions: Findings of this study may form a foundation for the corpus of knowledge explaining the outcome differences in treatment of patients with metastatic breast cancer, potentially helping to create tailored counseling and personalized treatment approaches for this vulnerable group.

Breast cancer is the cancer with the most prevalence of 43.3% and the mortality rate that reaches 12.9%. The prognosis of breast cancer can be affected by diabetes mellitus (DM), so that efforts to control DM through antidiabetic therapy are very necessary, but antidiabetic therapy is also reported to be associated with the prognosis of breast cancer. The purpose of this study was to determine the relationship of diabetes and antidiabetic use to recurrence in breast cancer patients. This study used a retrospective cohort design, involving 176 female non-metastatic breast cancer patients who received chemotherapy, consisting of 88 patients with DM and 88 non-DM patients. The exposures in the study were diabetes mellitus and the types of antidiabetic drugs (metformin and non metformin based therapy), while the study output was the recurrence of breast cancer. The research data was obtained from the patient’s medical records at RSUP Dr. Sardjito Yogyakarta. Research analysis used Chi-square, Kaplan Meier method and Cox-regression to estimate Hazard Ratio with 95% confidence interval. The results showed DM in breast cancer patients was associated with increased the risk of recurrence (HR 2,458; 95% CI 1,571-3,846, log rank test P=0,000), while the use of antidiabetic types (metformin and nonmetformin) to control DM in breast cancer patients was not associated with the risk of recurrence (HR 1.391; 95% CI 0.816 - 2.370, log rank test P=0.210). Further research is warranted by monitoring blood glucose levels regularly.

Introduction: Adjuvant trastuzumab has been used in human epidermal growth factor-2 (HER2) breast cancer to improve survival but with concern of cardiotoxicity. Our study is the first to review efficacy and toxicity of adjuvant trastuzumab in Malaysia. Methods: This is a retrospective cohort study on HER2 non metastatic breast cancer patients in University Malaya Medical Centre diagnosed between October 2006 and May 2011. Two cohorts were created based on whether or not they received adjuvant trastuzumab. Disease free survival (DFS) and overall survival (OS) for both groups were estimated using Kaplan Meier method and compared using Log rank test. Cox proportional hazards regression models analysed for potential covariates of age, tumour size and grade, node and estrogen receptor (ER) status. Trastuzumab cardiotoxicity was defined as left ventricular systolic dysfunction or heart failure with or without symptoms and graded using Common Terminology Criteria for Adverse Events (CTCAE 4.0). Results: 170 HER2 non metastatic breast cancer patients were identified. Thirty-three received trastuzumab and 136 did not. Median age was 53.4 ± 10.3 years old. Significantly more ER negative patients received trastuzumab. Four years DFS in ‘trastuzumab’ versus ‘no trastuzumab’ cohort was 90.9% vs 74.5% (p = 0.027). Four years OS was 91% vs 84.7% (p = 0.30) respectively. Majority tolerated trastuzumab with no toxicity. Five patients (15.2%) experienced cardiotoxicity (all grade I).Conclusions: Adjuvant trastuzumab significantly improved DFS in HER2 breast cancer. Treatment was well tolerated. With this we propose the justification for adjuvant trastuzumab in HER2 breast cancer in our population.

Background Reports on the incidence and prognoses of lung metastases when diagnosing breast cancer patients with different subtypes are limited. Our study investigated the effect of molecular sub-typing stratification on the prognoses of lung metastatic breast caner patients. Methods Patients with breast cancer and lung metastases were identified from Surveillance, Epidemiology and End Results population-based data between 2010 and 2015. Univariate and multivariate Cox regression analyses were performed to identify risk factors and prognoses, overall survival (OS) and breast cancer-specific survival for patients with breast cancer lung metastases. Results We identified 6,516 patients with lung metastatic breast cancer, representing 1.7% of the entire cohort and 30.4% of the subset with metastatic disease. This included 2,940 hormone receptor (HR)+/HER2− patients, 852 HR+/HER2+ patients, 547 HR−/HER2+ patients and 983 triple-negative patients. The median OS for all lung metastatic patients was 13 months. Multivariate analysis revealed that those lung metastatic breast cancer patients of older age (>80), black race, with poorly differentiated tumors, carcinoma histology, triple-negative subtype, more metastatic sites and no surgery, and no chemotherapy showed significantly poor survival, both overall and breast cancer-specific. Conclusions Our findings show that molecular sub-type and more metastatic sites might have significant influence on the incidence and prognosis of breast cancer lung metastases. We also identified several prognostic factors that could guide therapy selection in the treatment of lung metastatic patients.

Abstract Background: Breast cancer is the most common cancer among women in the world. NKX6.1 is proved to be involved in several human cancers, but fewer researches have reported the functional roles of NKX6.1 in breast cancer. In this study, we investigated the clinical significance of NKX6.1 expression in breast cancer prognosis.Methods: The expression level of NKX6.1 in breast cancer tissues and paired non-cancerous tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Chi-square test was applied to evaluate the relationship between NKX6.1 expression and clinicopathologic parameters. The overall survival of breast cancer patients were analyzed by Kaplan-Meier method with log rank test. Additionally, cox regression analysis was used for prognosis analysis.Results: NKX6.1 expression level is increased in breast cancer tissues (P<0.001). Moreover, the elevated levels were significantly correlated with tumor size (P=0.002), TNM stage (P=0.018) and lymph node metastasis (P=0.007). In addition, breast cancer patients with high NKX6.1 level had a poorer overall survival than those with low level (log rank test, P=0.001). NKX6.1 was an independent prognostic factor for breast cancer (HR=2.961, 95%CI=1.368-6.411, P=0.006).Conclusions: NKX6.1 is up-regulated in breast cancer, which may be a potential prognostic biomarker for the cancer.

Over Time

Monitoring treatment response in metastatic breast cancer currently consists mainly of radiological and clinical assessments. These methods have high inter-observer variation, suboptimal sensitivity to determine response to treatment and give little insight into the biological characteristics of the tumor. Assessing circulating tumor DNA (ctDNA) over time could be employed to address these limitations. Several ways to quantify and characterize ctDNA exist, based on somatic mutations, copy number variations, methylation, and global circulating cell-free DNA (cfDNA) fragment sizes and concentrations. These methods are being explored and technically validated, but to date none of these methods are applied clinically. We systematically reviewed the literature on the use of quantitative ctDNA measurements over time to monitor response to systemic therapy in patients with metastatic breast cancer. Cochrane, Embase, PubMed and Google Scholar databases were searched to find studies focusing on the use of cfDNA to longitudinally monitor treatment response in advanced breast cancer patients until October 2020. This resulted in a total of 33 studies which met the inclusion criteria. These studies were heterogeneous in (pre-)processing procedures, applied techniques and design. An association between ctDNA and treatment response was found in most of the included studies, independent of the applied assay. To implement ctDNA-based response monitoring into daily clinical practice for metastatic breast cancer patients, sample (pre-) processing procedures need to be standardized and large prospectively collected sample cohorts with well annotated clinical follow-up are required to establish its clinical validity.
