Fang-Xia-Dihuang decoction inhibits breast cancer progression induced by psychological stress via down-regulation of PI3K/AKT and JAK2/STAT3 pathways:An in vivo and a network pharmacology assessment

Background:The development and prognosis of breast cancer are intricately linked to psychological stress.In addition,depression is the most common psychological comorbidity among breast cancer survivors,and reportedly,Fang-Xia-Dihuang decoction(FXDH)can effectively manage depression in such patients.However,its pharmacological and molecular mechanisms remain obscure.Methods:Public databases were used for obtaining active components and related targets.Main active components were further verified by ultra-high-performance liquid chromatography-high-resolution mass spectrometry(UPLC-HRMS).Protein–protein interaction and enrichment analyses were taken to predict potential hub targets and related pathways.Molecule docking was used to understand the interactions between main compounds and hub targets.In addition,an animal model of breast cancer combined with depression was established to evaluate the intervention effect of FXDH and verify the pathways screened by network pharmacology.Results:174 active components of FXDH and 163 intersection targets of FXDH,breast cancer,and depression were identified.Quercetin,methyl ferulate,luteolin,ferulaldehyde,wogonin,and diincarvilone were identified as the principal active components of FXDH.Protein–protein interaction and KEGG enrichment analyses revealed that the phosphoinositide-3-kinase–protein kinase B(PI3K/AKT)and Janus kinase/signal transducer and activator of transcription(JAK2/STAT3)signaling pathways played a crucial role in mediating the efficacy of FXDH for inhibiting breast cancer progression induced by depression.In addition,in vivo experiments revealed that FXDH ameliorated depression-like behavior in mice and inhibited excessive tumor growth in mice with breast cancer and depression.FXDH treatment downregulated the expression of epinephrine,PI3K,AKT,STAT3,and JAK2 compared with the control treatment(p<0.05).Molecular docking verified the relationship between the six primary components of FXDH and the three most important targets,including phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha(PIK3CA),AKT,and STAT3.Conclusion:This study provides a scientific basis to support the clinical application of FXDH for improving depression-like behavior and inhibiting breast cancer progression promoted by chronic stress.The therapeutic effects FXDH may be closely related to the PI3K/AKT and JAK2/STAT3 pathways.This finding helps better understand the regulatory mechanisms underlying the efficacy of FXDH.

The accuracy of magnetic resonance imaging and ultrasound in evaluating the size of early-stage breast neoplasms

Objective Breast cancer is the most frequently diagnosed cancer in women. Accurate evaluation of the size and extent of the tumor is crucial in selecting a suitable surgical method for patients with breast cancer. Both overestimation and underestimation have important adverse effects on patient care. This study aimed to evaluate the accuracy of breast magnetic resonance imaging(MRI) and ultrasound(US) examination for measuring the size and extent of early-stage breast neoplasms.Methods The longest diameter of breast tumors in patients with T_(1–2)N_(0–1)M_0 invasive breast cancer preparing for breast-conserving surgery(BCS) was measured preoperatively by using both MRI and US and their accuracy was compared with that of postoperative pathologic examination. If the diameter difference was within 2 mm, it was considered to be consistent with pathologic examination.Results A total of 36 patients were imaged using both MRI and US. The mean longest diameter of the tumors on MRI, US, and postoperative pathologic examination was 20.86 mm ± 4.09 mm(range: 11–27 mm), 16.14 mm ± 4.91 mm(range: 6–26 mm), and 18.36 mm ± 3.88 mm(range: 9–24 mm). US examination underestimated the size of the tumor compared to that determined using pathologic examination(t = 3.49, P < 0.01), while MRI overestimated it(t =-6.35, P < 0.01). The linear correlation coefficients between the image measurements and pathologic tumor size were r = 0.826(P < 0.01) for MRI and r = 0.645(P < 0.01) for US. The rate of consistency of MRI and US compared to that with pathologic examination was 88.89% and 80.65%, respectively, and there was no statistically significant difference between them(χ~2 = 0.80, P > 0.05).Conclusion MRI and US are both effective methods to assess the size of breast tumors, and they maintain good consistency with pathologic examination. MRI has a better correlation with pathology. However, we should be careful about the risk of inaccurate size estimation.

Symptom burden in advanced breast cancer patients and its association between death anxiety and psychological distress

Objective:Recent research has documented psychological distress in advanced breast cancer(ABC)patients,but few studies have examined how death anxiety is affected by the symptom burden.Therefore,this study aims to explore the association among symptom burden,death anxiety and psychological distress(depression and anxiety)in ABC patients.Methods:This cross-sectional study used the Death and Dying Anxiety Scale(DADDS),9-item Patient Health Questionnaire(PHQ-9),General Anxiety Disorder-7(GAD-7)and MD Anderson Symptom Inventory(MDASI)to assess death anxiety,depression,anxiety,and symptom burden,respectively.Bias-corrected bootstrapping methods were used to estimate indirect effects and 95%confidence intervals.Results:Two hundred ABC patients completed the questionnaires.All of the respondents were females,with a mean age of 50±10 years.Initial correlation analyses revealed significant associations of death anxiety with depression(r=0.57,P<0.001),anxiety(r=0.60,P<0.001)and symptom burden(r=0.43,P<0.001).Moreover,depression(r=0.53,P<0.001)and anxiety(r=0.45,P<0.001)were significantly correlated with symptom burden.An analysis using Hayes’PROCESS macro revealed the partial effecting role of death anxiety in the relationship between depression and symptom burden,and between anxiety and symptom burden(contributions to the total effect of 0.247 and 0.469,respectively).Conclusions:This study provides insight into the relationship between death anxiety and symptom burden.The results suggest that interventions addressing death anxiety may be more effective for alleviating the depression and anxiety experienced by ABC patients with a symptom burden.

The Relationship between Workplace Stressors and Job Strain with Psychological Distress among Employed Malaysian Breast Cancer Survivors

Evidence showed occupational factors may contribute distress to breast cancer survivors, however, very few studies focused on the occupational factors and job strain among breast cancer survivors. This study examined the relationship between job strain and workplace stressors with psychological distress among employed breast cancer survivors after the completion of their medical treatment. Study subject were outpatients of 2 hospitals and members of 4 breast cancer support groups. They were requested to fill up the Job Content Questionnaires (JCQ), the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) were filled up by the selected respondents. On simple logistic regression, psychological job demand and job strain were significantly associated with anxiety, distress on HADS-T and DT at (p < 0.001). While, psychological job demand (p < 0.001), social support (p = 0.047) and job strain (p < 0.001) were significantly associated with depression. Results showed survivors with high job strain has 4.74 time the odds of having anxiety (p < 0.001). Survivors with high psychological job demand have 8.08 time the odds of getting depression (p < 0.001). On the other hand, social support served as a protective factor of depression, (p = 0.041). Survivors with high psychological job demand were 4.4 time the odds of having distress (HADS-T) (p = 0.012). As a conclusion, survivors who experienced high psychological job demand, low social support and high job strain were reported with anxiety, depression or psychological distress.

Bibliometrics analysis of psychological intervention in breast cancer patients

Background:In order to provide some references and direction for further research on psychological intervention for breast cancer patients,we analyzed the breast cancer patients,learned its research status,and found out the existing problems.Methods:We retrieved relevant literatures on psychological intervention for breast cancer patients from databases such as CNKI,Wanfang data,VIP and CBM.Note Express 3.2 was used for bibliometric analysis.Results:A total of 60 articles were included.We found that the research institutions were mainly hospitals.There was a lack of attention to special breast cancer patients,efficacy comparison trials of different intervention and cooperation during institutions.Research design was not rigorous enough:lack of pertinence of populations,unclear and short intervention interval,low repeatability of research trials,low transparency of intervention,and defects in intervention quality control.Conclusion:Clinical trials on psychological intervention for breast cancer patients should pay more attention to special breast cancer populations.Researchers should correctly grasp related research trends,seek cooperation opportunities with other institutions,and improve the quality of their own research and ensure the innovation and scientificity of trial design.Meanwhile,researchers can further explore the psychological intervention methods for special breast cancer populations,and conduct comparative studies on the efficacy of different intervention measures.

Adjuvant therapy for hormone receptor-positive breast cancer: Perspective from a survey on breast cancer physicians' acceptance of practice-changing data

A cross-sectional online survey was conducted.A high proportion of the Chinese breast cancer(BC)physician respondents(n=77)would prescribe extended adjuvant endocrine therapy(AET)with aromatase inhibitors(AI)beyond 5 years for postmenopausal females with BC,especially those with higher risk.Respondents with≥15 years of clinical experience were more likely to prescribe a longer duration of AET for low-risk patients.Half of the respondents considered intermittent letrozole as an acceptable option.Most respondents would prescribe adjuvant chemotherapy to genomic high-intermediate risk[Oncotype DX recurrence score(RS)21-25]females aged≤50 years regardless of the clinical risk classification.

Breast cancer: Epidemiology, risk factors and screening

Breast cancer is a global health concern with a significant impact on the well-being of women. Worldwide, the past several decades have witnessed changes in the incidence and mortality of breast cancer. Additionally,epidemiological data reveal distinct geographic and demographic disparities globally. A range of modifiable and non-modifiable risk factors are established as being associated with an increased risk of developing breast cancer.This review discusses genetic, hormonal, behavioral, environmental, and breast-related risk factors. Screening plays a critical role in the effective management of breast cancer. Various screening modalities, including mammography,ultrasound, magnetic resonance imaging(MRI), and physical examination, have different applications, and a combination of these modalities is applied in practice. Current screening recommendations are based on factors including age and risk, with a significant emphasis on minimizing potential harms to achieve an optimal benefits-to-harms ratio. This review provides a comprehensive insight into the epidemiology, risk factors, and screening of breast cancer. Understanding these elements is crucial for improving breast cancer management and reducing its burden on affected individuals and healthcare systems.

Effectiveness of Post-Traumatic Growth Intervention to Promote Positive Post-Traumatic Traits in Chinese Breast Cancer Patients:A Randomized Controlled Trial

Objective:The purpose of this study was to evaluate the effectiveness of post-traumatic growth(PTG)model-based intervention to improve positive psychological traits in Chinese breast cancer patients.Design:A randomized control trial of a psychological group intervention based on PTG model.Methods:The Clinical Trial was registered on 17 August 2019 at Chinese Clinical Trials.gov with Registration number ChiCTR1900025264.A total of 92 patients with breast cancer were recruited.The participants were randomly assigned to the experimental group(n=46)and the control group(n=46).A six-session psychological group intervention based on PTG model was implemented in the experimental group,and a six-session health education was implemented in the control group.The outcomes weremeasured at baseline(pre-intervention),3 weeks,6 weeks after the intervention.The primary outcome was posttraumatic growth assessed by the Chinese version of the Post-Traumatic Growth Inventory(PTGI);Secondary outcomes included psychological resilience,family resilience,rumination,and self-disclosure.Results:A total of 87 patients with breast cancer completed this study,including 44 patients in the experimental group and 43 patients in the control group.There was no significant difference in baseline data of breast cancer patients between the two groups except for the treatment regimen(p>0.05).The two groups were compared after the intervention;the interaction effects between the total scores of posttraumatic growth,family resilience,and self-disclosure and the time term were statistically significant(p<0.05),indicating that the trend of change in total scores of post-traumatic growth,family resilience,and self-disclosure differed between the experimental and control groups over time,and the scores improved in the experimental group were significantly higher than those in the control group.The comparison of psychological resilience and total score of rumination at each time point was statistically significant(p<0.05),indicating that group intervention based on the PTG model could improve the psychological recovery ability and rumination level of the experimental group.Conclusion:The psychological group intervention based on the PTG model significantly improved post-traumatic growth,family resilience,and self-disclosure in patients with breast cancer.However,the impact on psychological resilience and rumination was relatively small.Long-term intervention is needed to further test the effect of the PTG model on psychological resilience and rumination.

Granular cell tumor of the breast:A case report and review of literature

BACKGROUND Granular cell tumor(GCT)of the breast(GCTB)is a rare neoplasm that can exhibit malignant characteristics both clinically and radiologically.This tumor can also coexist and colocalize with breast carcinoma.CASE SUMMARY We present a patient with this uncommon tumor and discuss the diagnostic and therapeutic approaches in order to further the knowledge of GCTB and prevent misdiagnosis and overtreatment.The characteristics of the tumor,methods of diagnosis,therapy and postoperative pathological outcomes were analyzed,and relevant literatures of GCTs were reviewed.The patient underwent surgery after core needle biopsy,and the excised neoplasm was sent for pathological examination.Histological analysis revealed nests of cells with abundant pink granular cytoplasm,confirming the diagnosis of GCTB.CONCLUSION As manifestations of GCT and malignancy can mimic each other,a careful histological examination is essential before major surgery.Treatment consisting of complete excision with close clinical follow-up is recommended.
