BackgroundTo characterize the clinical and pathological features and survival of patients with human epidermal growth factor receptor 2 (HER2)-low breast cancer in China.MethodsThe China National Cancer Center database was used to identify 1,433 metastatic breast cancer patients with HER2-negative disease diagnosed between 2005 and 2015. Clinicopathological features, survival, and prognosis information were extracted. Overall survival (OS) was estimated using the Kaplan–Meier method and compared using the log-rank test. Prognostic factors associated with OS were analyzed using Cox regression model with 95% confidence interval (95% CI).ResultsThere were 618 (43.1%) and 815 (56.9%) HER2-low and HER2-zero tumors out of 1,433 tumors, respectively. The proportion of hormone receptor (HR)-positive tumors was significantly higher in HER2-low tumors than in those with HER2-zero tumors (77.8% vs. 69.2%, p < 0.001). Patients with HER2-low tumors survived significantly longer than those with HER2-zero tumors in the overall population (48.5 months vs. 43.0 months, p = 0.004) and HR-positive subgroup (54.9 months vs. 48.1 months, p = 0.011), but not in the HR-negative subgroup (29.5 months vs. 29.9 months, p = 0.718). Multivariate regression analysis revealed that HER2-low tumors were independently associated with increased OS in HER2-negative population (HR: 0.85, 95% CI: 0.73–0.98, p = 0.026).ConclusionOur findings demonstrate that HER2-low tumors could be identified as a more distinct clinical entity from HER2-zero tumors, especially for the HR-positive subgroup. A more complex molecular landscape of HER2-low breast cancer might exist, and more precise diagnostic algorithms for HER2 testing could be investigated, thus offering new therapeutic targets for breast cancer treatment.

BackgroundThe aim of this study was to investigate the status of serum lipids during endocrine therapy.MethodsWe retrospectively analysed lipid profiles during the 5-year treatment of 1487 consecutive postoperative BC patients. Lipid parameters included triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C). Those biomarkers were measured at baseline and 1, 2, 3, 4 and 5 years following the initiation of endocrine therapy.ResultsFor premenopausal BC patients, LDL levels rapidly decreased at 1 year in the tamoxifen (TAM) group compared with baseline levels (p<0.05), and this decline remained for the following 4 years. Additionally, LDL levels were significantly lower in the TAM group than in the nonendocrine group at all assessment time points (p<0.05). Similarly, TC levels also decreased in the TAM group compared with baseline levels at all assessment time points (p<0.05), and compared with the levels in the nonendocrine group, TC levels were also lower for the first 4 years. For postmenopausal BC patients, there was no significant difference in the lipid profiles (TG, TC, LDL and HDL) in the letrozole (LET), anastrozole (ANA) or exemestane (EXE) groups compared with the nonendocrine group. For patients who received TAM, compared with the nonendocrine group, TC levels decreased at 1 year, and LDL levels decreased at 1 and 2 years.ConclusionsTAM may improve LDL and TC levels in premenopausal BC patients. In postmenopausal BC patients, aromatase inhibitors (AIs) may have no adverse effects on lipid profiles, and TAM may have limited beneficial effects on serum lipids.

Background: To assess role of platelet aggregation in metastatic breast cancer patients.Methods:40 cases (Group I) of metastatic breast cancer patients and equal number of healthy control (Group II) subjects were included. Platelet aggregation studies in vitro using ADP and Thrombin were performed using an optical aggregometer. Detection of platelet aggregation was done by Chrono log series 490 dual and four channel optical aggregometer systems.Results:There were 4 subjects in group I and 12 in group II having ADP <60, 26 subjects in group I and 28 in group II with ADP 61-72 and 10 subjects in group I with ADP >72. Low thrombin <58 was seen in 8 in group II, normal thrombin between 61-72 was seen among 11 in group I and 32 in group II and high thrombin >82 among 29 in group I respectively. Amongst patients with normal platelet count, 14 patients had platelet aggregation with ADP in the normal range and 4 patients had platelet aggregation with ADP in the lower range. In patients with high platelet count, 12 showed aggregation in the normal range, and 10 patients showed aggregation in the higher range which was statistically significant (P< 0.05) (Table III, Graph II).Conclusion: Platelet aggregation has an important part to play in the tumor metastasis of breast cancer patients.

Objective: To evaluate the clinical curative effect of neoadjuvant chemotherapy combined with immunotherapy and its impact on immunological function and the expression of ER, PR, HER-2 and SATB1 in HER-2-positive breast cancer patients. Methods: The subjects of study were 80 patients with HER-2-positive breast cancer. Enrolled patients were randomly divided into two groups, with 40 cases in each group at The Fourth Affiliated Hospital of Hebei Medical University from March 2018 from March 2021. Patients in the control group were provided with neoadjuvant chemotherapy using TAC regimen merely; while those in the study group received oral administration of Apatinib Mesylate (500mg/d; three weeks a cycle) on the basis of the TAC regimen. Further comparative analysis was performed focusing on the therapeutic effect and adverse drug reaction rate of the two groups; levels of CD3+, CD4+, CD8+ and CD4+/CD8+ of T lymphocyte subsets in the two groups before and after treatment; as well as the expressions of ER, PR, HER-2 and SATB1 in the two groups before and after treatment. Results: The total response rate was 77.5% and 55% in the study group and the control group, respectively, with an obviously better outcome in the former group than that in the latter group (p=0.03). Meanwhile, the incidence of adverse reactions was 40% in the study group and 45% in the control group, without statistical difference (p=0.65). There were statistically significant differences that the levels of CD3+, CD4+, and CD4+/CD8+ in the study group were significantly higher when compared with those in the control group after treatment (CD3+, p=0.00; CD4+, p=0.02; CD4+/CD8+, p=0.00); while no evident change was observed in the level of CD8+ (p=0.88). After treatment, the positive expression rates of ER, HER-2 and SATB1 were remarkably lower in the study group than those in the control group, showing statistically significant differences (ER, HER-2, p=0.03; SATB1, p=0.02). However, there was no statistically significant difference in the positive expression rate of PR between the study group and the control group (P=0.80). Conclusions: Neoadjuvant chemotherapy combined with immunotherapy has significant effect on the treatment of HER-2-positive breast cancer patients. It can result in the significant enhancement of T lymphocyte function, obvious improvement in the negative converse rates of ER, HER-2 and SATB1, and no evident increase in the adverse drug reactions. The proposed therapeutic approach is safe, effective, and have certain clinical value. doi: How to cite this:Chen Z, Sang M, Geng C, Hao W, Jia H.

Abstract Objective: To characterize the fear of cancer recurrence (FCR) and its relationship with anxiety and depression and quality of life (QoL) among Chinese breast cancer (BC) patients in China. Methods: Patients completed the questionnaires of QLQ-C30, QLQ-BR32 and HAD to assess FCR, QoL, anxiety and depression before radiotherapy. A cross-sectional analysis was performed. Chi-square and non-parametric tests and multivariate ordinal logistic regressions (mOLR) were utilized for reference analysis. Final covariates included age, BMI, TNM, surgery, chemotherapy, pain, and sleep disturbance. Results: From July 2015 to December 2016, 463 patients were prospectively enrolled. Their age mean (range) were 47 (19 - 89) years old. In total, 327 patients (70.6%) reported having FCR ‘a little bit’ (51.2%), ‘some’ (12.1%) and ‘very much’ (7.3%) in the past week. FCR severity ordered above (incl. ‘no’) was associated with anxiety score (median 1.5, 5.0, 7.0, 8.5 and level (‘abnormal’ rate 0%, 3.4%, 12.5%, 26.5%), depression score (median 2.0, 4.0, 6.0, 6.5) and level (‘abnormal’ rate 2.2%, 3.4%, 5.4%, 17.7%) (all p<0.001). mOLR showed that compared to ‘no’, three higher levels of FCR were associated with one level increase of anxiety with OR (p) as 1.983 (0.076), 4.291 (0.001), 8.282 (<0.001) and depression with OR (p) as 1.903 (0.062), 2.262 (0.065), 4.205 (0.004), respectively. FCR severity also was inversely associated with most QoL function scores (p<0.001). Conclusions: FCR was prevalent in Chinese BC patients and linearly associated with anxiety, depression and low QoL. It seems that a single-item question for FCR is a valid surrogate tool for distress screening in this population.

Abstract High levels of circulating estradiol (E2) are associated with increased risk of breast cancer, whereas its relationship with breast cancer prognosis is still unclear. We evaluated the effect of E2 concentration on survival endpoints among 8766 breast cancer cases diagnosed between 2005 and 2017 from the Tianjin Breast Cancer Cases Cohort. Levels of serum E2 were measured in pre-menopausal and post-menopausal women. Multivariable-adjusted Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) between quartile of E2 levels and overall survival (OS) and progression-free survival (PFS) of breast cancer. The penalized spline was then used to test for non-linear relationships between E2 (continuous variable) and survival endpoints. 612 deaths and 982 progressions occurred over follow-up through 2017. Compared to women in the quartile 3, the highest quartile of E2 was associated with reduced risk of both PFS in pre-menopausal women (HR=1.79, 95% CI: 1.17-2.75, P=0.008) and OS in post-menopausal women (HR=1.35, 95% CI: 1.04-1.74, P=0.023). OS and PFS in pre-menopausal women exhibited a nonlinear relation (“L-shaped” and “U-shaped”, respectively) with E2 levels. However, there was a linear relationship in post-menopausal women. Moreover, patients with estrogen receptor-negative (ER-negative) breast cancer showed a “U-shaped” relationship with OS and PFS in pre-menopausal women. Pre-menopausal breast cancer patients have a plateau stage of prognosis at the intermediate concentrations of E2, whereas post-menopausal patients have no apparent threshold, and ER status may have an impact on this relationship.

Abstract Background: PDZ-binding kinase/T lymphokine-activated killer cell-derived protein kinase (PBK/TOPK) is a potential prognostic indicator for patients with breast cancer. The objective of the present study was to explore the relationship between PBK/TOPK expression and clinicopathological indicators as well as the survival of patients with breast cancer.Methods: Immunohistochemical staining was used to detect the expression of PBK/TOPK in 202 cases of breast cancer tissues. The relationship between PBK/TOPK and clinicopathological parameters was evaluated using Spearman's rank-order correlation. The difference in PBK/TOPK expression among different molecular types was analyzed with the chi square test. Kaplan-Meier analysis was used to create a survival curve and the log rank test was used to analyze the overall survival (OS) and disease-free survival (DFS). Prognostic correlation was assessed using univariate and multivariate Cox regression analyses.Results: Among 202 breast cancer samples, PBK/TOPK was expressed ('+' and '++') in 182 samples (90.1%). In addition, the histological grade, TNM stages, lymph node metastasis, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2), and Ki-67 were positively associated with PBK/TOPK expression. With regard to the molecular type, the expression of PBK/TOPK is different. The expression level of PBK/TOPK was negatively correlated with both the OS and DFS of breast cancer patients. The difference in the above results is meaningful (P<0.05).Conclusions: PBK/TOPK is over-expressed in breast cancer and the expression is closely related to the clinicopathological characteristics of the disease. Breast cancer patients with high expression of PBK/TOPK have a poor prognosis. Therefore, health care providers can optimize breast cancer management using this indicator.
