The Clinicopathological features and survival outcomes of patients with different metastatic sites in stage IV breast cancer

Abstract Background The features and survival of stage IV breast cancer patients with different metastatic sites are poorly understood. This study aims to examine the clinicopathological features and survival of stage IV breast cancer patients according to different metastatic sites. Methods Using the Surveillance, Epidemiology, and End Results database, we restricted our study population to stage IV breast cancer patients diagnosed between 2010 to 2015. The clinicopathological features were examined by chi-square tests. Breast cancer-specific survival (BCSS) and overall survival (OS) were compared among patients with different metastatic sites by the Kaplan-Meier method with log-rank test. Univariable and multivariable analyses were also performed using the Cox proportional hazard model to identify statistically significant prognostic factors. Results A total of 18,322 patients were identified for survival analysis. Bone-only metastasis accounted for 39.80% of patients, followed by multiple metastasis (33.07%), lung metastasis (10.94%), liver metastasis (7.34%), other metastasis (7.34%), and brain metastasis (1.51%). The Kaplan-Meier plots showed that patients with bone metastasis had the best survival, while patients with brain metastasis had the worst survival in both BCSS and OS (p < 0.001, for both). Multivariable analyses showed that age, race, marital status, grade, tumor subtype, tumor size, surgery of primary cancer, and a history of radiotherapy or chemotherapy were independent prognostic factors. Conclusion Stage IV breast cancer patients have different clinicopathological characteristics and survival outcomes according to different metastatic sites. Patients with bone metastasis have the best prognosis, and brain metastasis is the most aggressive subgroup.

Abstract Background: The features and survival of stage IV breast cancer patients with different metastatic sites are not very clear recently. This study aims to determine the clinicopathological features and survival of stage IV breast cancer according to different metastatic sites. Methods: Exploiting the Surveillance, Epidemiology, and End Results database, we included stage IV breast cancer patients diagnosed between 2010 to 2015. The clinicopathological features were examined by chi‐square tests. Breast cancer‐specific survival (BCSS) and overall survival (OS) were compared among patients with different metastatic sites by Kaplan‐Meier method with the log‐rank test. Univariate and multivariate analyses were also performed using the Cox proportional hazard model to identify statistically significant prognostic factors. Results: A total of 18322 patients were identified for survival analysis. Bone metastasis not otherwise specified accounted for 39.80% of patients, followed by multiple metastases (33.07%), lung metastasis (10.94%), liver metastasis (7.34%), other metastasis (7.34%), and brain metastasis (1.51%). The Kaplan‐Meier plots displayed that patients with bone metastasis had the best survival while patients with brain metastasis had the worst survival in both BCSS and OS (P < 0.001, respectively). Multivariate analyses showed that age, race, marital status, grade, tumor subtype, tumor size, surgery of primary cancer, the experience of radiotherapy or chemotherapy were independent prognostic factors. Conclusion: Stage IV breast cancer patients have different clinicopathological characteristics and survival outcomes according to different metastatic sites. Patients with bone metastasis have an excellent prognosis, while brain metastasis is the most aggressive subgroups.

e13065 Background: To analyze the correlation between tumor size and metastatic site in first-diagnosed stage IV breast cancer patients. Methods: Stage IV breast cancer patients diagnosed from 2010 to 2015 were screened by the Surveillance, Epidemiology, and End Results (SEER) database. The characteristics of clinical variables were represented by a frequency table, and the Chi-square test was used for comparison. At the same time, the Chi-square test was used to analyze the relationship between tumor size and organ metastasis. Correlation between tumor size and the prognosis of patients was contributed by KM curve and Log-rank test. Results: Regardless of tumor size, the proportion of bone metastasis was higher and brain metastasis was lower in breast cancer patients. There were significant differences in the site of metastases based on different subtype. Luminal A and Luminal B breast cancer had the highest proportion of bone metastases; brain metastasis accounted for the highest proportion in triple-negative breast cancer (TNBC); while the incidence of liver metastasis was the highest in Her-2(+) breast cancer. At the same time, the results indicated that Luminal A breast cancer with a tumor size > 5 cm was more likely to develop multi-site metastasis and lung metastasis, while Luminal B breast cancer with a tumor size ≤ 5 cm was more likely to develop liver metastasis. The results also revealed that TNBC patients with a tumor size of 0 - 2cm were more likely to develop bone metastasis than those with a tumor size > 5 cm, and the incidence of lung metastasis in triple-negative patients showed an increasing trend with the increase of tumor size. Conclusions: Based on subtype, we found that there was a significant difference between tumor size and metastatic site in patients with stage IV breast cancer, and the difference was statistically significant. This study provided evidence-based basis for decision-making of stage IV breast cancer treatment.

Stage Iv Breast Cancer

CA 15.3 is an antigen expressed by human breast carcinoma cells, and defined by two monoclonal antibodies, 115D8 and DF3. We used IRMA to determine the circulating serum levels of CA 15.3 in 1178 subjects with breast cancer, non-breast malignancies, benign diseases and controls. A threshold level of 40 U/ml was established with 140 healthy controls and 650 patients with benign diseases (respectively 0% subjects and 1.5% patients had abnormal antigen levels). Elevated CA 15.3 was found in 12 of 184 patients with malignancies different from breast cancer (6.5%), either epithelial carcinomas with distant metastases, mainly in the liver, or primary liver tumors. Breast cancer patients (n=204) were analysed by prior therapy, UICC stage and WHO response to therapy. Eight of 134 (5.9%) patients with stage II or III breast cancer at presentation and no evidence of disease (NED) had elevated CA 15.3. All of 22 patients with stage IV breast cancer not responding to therapy (SD and PD) had antigen levels > 40 U/ml, as did 10 of 34 (29.4%) stage IV patients in objective response (CR+PR). Three of 14 pretreatment patients had abnormal marker levels, and they later proved to have distant metastases. Serum CA 15.3 values were statistically different (p < 0.01) in NED (20.6 ± 11.2 U/ml), CR+PR (33.5 ± 24.0 U/ml), stable disease (98.8 ± 50.4 U/ml) and progressive disease (> 200 U/ml) breast cancer patients. Our results suggest that circulating CA 15.3 antigen levels agree with the stage of breast cancer and with the response to therapy.
