Breast cancer patients and survivors deal with physical and psychological challenges due to oncological treatments. The existing literature highlights the importance of compassion in reducing the main cancer-related effects in terms of emotions, quality of life, and dysfunctional coping skills. Over the past few years, compassion-based interventions (CBIs) have been considered an interesting approach to reduce anxiety and depression symptoms and improve quality of life and well-being. However, there have not been many studies that show the benefits of these interventions in breast cancer patients and survivors. The primary objective of this systematic review is to provide evidence of the impact of CBIs on specific variables identified in the literature as affected by this pathology. The variables that will be studied are (a) emotional issues (e.g., anxiety, stress, and depression symptoms); (b) quality of life; and (c) positive coping skills. A systematic search during the previous 10 years up to November 2023 was conducted following the PRISMA guidelines across multiple databases, such as PubMed, Web of Science, PsycINFO, and Scopus. Nine eligible randomized controlled trials were included in this article, with a total of 813 breast cancer patients and survivors. Findings show that CBIs increased compassion, mindful observation, and acting with awareness skills, leading to a significant reduction of anxiety and stress levels, depression, and negative affect. Additionally, less body image distress and greater body appreciation were reported as a consequence of the interventions. This review shows the CBI’s efficacy on emotions, positive coping skills, and quality of life in breast cancer patients and survivors. Guidelines for future studies are listed to promote CBIs as a clinically useful intervention for breast cancer patients and survivors.
While studies have examined the effects of large-scale disasters on disaster-vulnerable individuals, these analyses may not capture the full impact. This study qualitatively explored the impacts of the March 2011 Fukushima triple disaster on patients with breast cancer and their families, aiming to highlight the importance of incorporating family narratives to grasp the full effect of large-scale disasters.
Methods
Utilizing the medical records from two hospitals, deceased patients with breast cancer from the disaster period were identified. Relatives were interviewed using a semi-structured approach. Thematic analysis was conducted via the Braun and Clarke method and Taguette transcription software.
Results
Interviews with seven family members of six patients revealed three main themes: the family’s caregiving burden and their deepened bonds with the patient, the patients’ extensive medical challenges and their physical and mental decline, and the shared confusion during the disaster due to resource shortages and evacuation dilemmas.
Conclusions
This study uncovered significant infrastructural issues such as reduced medical support and the heavy caregiving load on families, amidst some strengthened relationships during a time of crisis. Future research should investigate these issues across various disaster contexts, and proactive measures should be implemented to prevent exacerbation of these challenges.
Breast cancer is a major global health issue, especially among women. Previous research has indicated a possible association between psychiatric conditions, particularly schizophrenia, and an increased risk of breast cancer. However, the specific risk of breast cancer in women with schizophrenia, compared with those with other psychiatric disorders and the general population, remains controversial and needs further clarification.
Aims
To estimate the risk of breast cancer among people with schizophrenia compared with people with other psychiatric disorders and people in the general population.
Method
We utilised medical claims data of women aged 18 to 80 years in the Korean National Health Information Database from 2007 to 2018. Individuals with schizophrenia were defined as women with ICD-10 codes F20 or F25 (n = 224 612). The control groups were defined as women with other psychiatric disorders (n = 224 612) and women in the general Korean population (n = 449 224). Cases and controls were matched by index date and age, in a 1:1:2 ratio. We estimated the hazard of breast cancer using the Cox proportional hazards model, adjusting for insurance premiums and medical comorbidities. Among the people with schizophrenia, we used the landmark method to estimate the association between duration of antipsychotic medication use and the incidence of breast cancer.
Results
In multivariable Cox regression models, the hazard rate of breast cancer was 1.26 times higher in the people with schizophrenia than in the general population (95% CI: 1.20–1.32). In comparison with the psychiatric patient group, the hazard ratio was 1.17 (95% CI: 1.11–1.28). Among women with schizophrenia, the hazard of breast cancer was greater among those who took antipsychotic medications for 1 year or more compared with those who took antipsychotics for less than 6 months.
Conclusions
Women with schizophrenia have an elevated risk of breast cancer, and long-term use of antipsychotics is associated with an increased risk of breast cancer.
This study compares tumor control probability (TCP) and normal tissue complication probability (NTCP) across different hypo-fractionated (HypoRT) and conventional breast radiotherapy regimens using radiobiological models.
Materials and methods:
Computed tomography data from 30 patients with left breast-conserving surgery were used to evaluate three HypoRT regimens (39 Gy and 41·6 Gy in 13 fractions, and 40 Gy in 15 fractions) and a conventional regimen (50 Gy in 25 fractions). Dose-volume histograms (DVHs) were extracted for radiobiological calculations using Equivalent Uniform Dose (EUD) and Poisson models for TCP, and EUD and LKB (Lyman-Kutcher-Burman) models for NTCP.
Results:
Conventional treatment achieved significantly higher TCP (95%) than all HypoRT regimens (p < 0·001), with no significant differences between HypoRT regimens (p > 0·05. The 39 Gy/13 fraction regimen showed the lowest lung NTCP (p < 0·05). HypoRT regimens had significantly lower NTCP for the lungs and heart compared to the conventional regimen (p < 0·01). TCP and NTCP values from Poisson and LKB models were higher than those from the EUD model (p < 0·01).
Conclusion:
HypoRT regimens reduced NTCP, with the lowest values in the regime of 39 Gy/13 fractions regimen, though the conventional regimen had higher TCP.
Mental health challenges are common following cancer diagnosis, negatively impacting treatment and quality of life for breast cancer (BC) patients. This pilot study provides an understanding of the impacts of BC diagnosis and care experiences on the mental health of patients seen at the Aga Khan University Hospital in Nairobi, Kenya. We conducted 40 in-depth interviews, including 10 women with newly diagnosed BC, 10 women with metastatic BC, 10 family members and 10 healthcare professionals. Data were transcribed, translated into English as needed and coded using Dedoose software. Following BC diagnosis, it was reported that patients faced various physical, social, psychological and spiritual factors affecting their mental health and quality of life. Our interviews with each group indicated that BC patients experienced feelings of stress, anxiety and depression related to treatments and accompanying side effects. Disclosure concerns, financial impacts, relationship strain and negative outlooks on life were common among BC patients. The findings indicate that BC diagnosis and care experiences influence mental health in this population. With this basis, understanding and addressing the mental health challenges of BC patients is crucial to improve mental health and quality of life.
Women with breast cancer show dissatisfaction with their appearance, a perception of loss of femininity and bodily integrity, and dissatisfaction with the outcome of the surgery. Body Appreciation (BA) is defined as positive attitudes toward one’s body, beyond satisfaction and dissatisfaction with one’s appearance. Although studies about the protective role of BA have increased, to the best of our knowledge, there are no published studies on the association between BA, body dissatisfaction, and distress in participants with breast cancer. The aims of this study are: (a) To analyze whether BA is a moderator of satisfaction with the body from before breast surgery to the one-year follow-up; and (b) to analyze whether BA is a moderator of distress from before breast surgery to the one-year follow-up. The sample consisted of 115 women diagnosed with breast cancer. Several hierarchical regression analyses were conducted. The results indicated that BA moderated the association between the appearance evaluation before the surgery and the appearance evaluation 12 months after the surgery. Although BA was a significative predictor of distress, it was not a moderator of distress from the moment before breast surgery to the one-year follow-up. This study highlights the importance of evaluating the construct of BA in participants with breast cancer using longitudinal designs and developing psychological interventions that focus on increasing BA.
Breast cancer is the most common cancer in women worldwide, necessitating substantial social support during diagnosis and treatment. This study examines the role of social capital in breast cancer management, focusing on the experiences of patients.
Objectives
The objective of the study was to explore the role of social capital in breast cancer management among women living with breast cancer in Lagos, Nigeria.
Methods
Using a qualitative design, the study recruited 23 women with breast cancer receiving treatment at a teaching hospital in Lagos, Nigeria. Data were content analyzed to identify themes related to social capital.
Results
The study found that social capital, crucial for breast cancer patients’ emotional and instrumental support, stems from various sources such as relatives, immediate family, spouses, places of worship, friends, and neighbors. Effective coping and management of the condition were facilitated through this support network. However, assistance from places of worship, friends, and neighbors was only accessible to those who openly acknowledged their health conditions and had established connections with these social groups. Relationships led to support only when there was a disclosure of the health condition.
Significance of results
(1) This finding reinforces the importance of integrating social support mechanisms including family, friends, and community networks into breast cancer management programs. (2) The study identifies diverse sources of social capital, including relatives, family, spouses, places of worship, friends, and neighbors, stressing the need for tailored support networks. (3) Research reveals the link between health condition disclosure and support accessibility from groups like places of worship and friends, and it emphasizes creating stigma-free environments for patients to disclose health status comfortably. (4) The study highlights family involvement in breast cancer management as crucial for effective coping. Healthcare professionals should prioritize interventions strengthening family support systems. (5) Findings of stress community support for better breast cancer outcomes, advocating for initiatives like support groups and awareness campaigns to boost social capital and aid affected individuals.
Conclusion
The study emphasizes the significance of involving family members in the breast cancer management process and highlights the need for support systems within families and communities to facilitate better outcomes for breast cancer patients.
The aim of this study was to develop a method for accurately measuring the intra-fraction motion in cine electronic portal imaging device (EPID) images of tangential breast irradiation.
Patients and methods:
The cine EPID images were acquired for 18 breast cancer patients during medial tangential breast radiotherapy. The skin surface and the chest wall were segmented separately in each EPID image using an automated MATLAB algorithm to obtain the magnitude of intra-fraction motion.
Results:
The patients had an average age of 55 years (range 43–69 years), with the highest observed displacement at 3·50 mm. The mean intra-fraction motion due to respiration for the skin surface and chest wall was 1·04 ± 0·24 mm and 1·10 ± 0·27 mm, respectively. The amount of intra-fraction motion showed no significant association with either the patient’s age or the side of the breast receiving the treatment.
Conclusion:
In this study, by utilising cine EPID technology and the automated MATLAB algorithm, the intra-fraction motion during breast radiotherapy treatment was accurately measured and analysed. Results indicate minimal skin surface and chest wall motion (approximately 1 mm), confirming negligible intra-fraction motions during conformal radiotherapy in breast cancer patients.
Depression is a common co-morbidity in women with breast cancer. Previous systematic reviews investigating cognitive behavioural therapy (CBT) for depression in this population based their conclusions on findings from studies with varying and often limited specificity, quality and/or quantity of CBT within their interventions.
Aim:
To determine the effectiveness of a specific, well-evidenced CBT protocol for depression in women with breast cancer.
Method:
Online databases were systematically searched to identify randomised controlled trials (RCTs) testing CBT (aligned to Beck’s protocol) as a treatment for depression in women with breast cancer. Screening, data extraction and risk of bias assessment were independently undertaken by two study authors. Both narrative synthesis and meta-analysis were used to analyse the data. The meta-analysis used a random effects model to compare CBT with non-active/active controls of depression using validated, self-report measures.
Results:
Six RCTs were included in the narrative synthesis, and five in the meta-analysis (n = 531 participants). Overall, CBT demonstrated an improvement in depression scores in the CBT condition versus active and non-active controls at post-intervention (SMD = –0.93 [95% CI –1.47, –0.40]). Narratively, five out of six RCTs reported statistically significant improvements in depression symptoms for CBT over control conditions for women with breast cancer.
Conclusion:
CBT aligned to Beck’s protocol for depression appears effective for treating depression in women with breast cancer. However, further research is needed for women with stage IV breast cancer. The clinical recommendation is that therapists utilise Beck’s CBT protocol for depression, whilst considering the complex presentation and adapt their practice accordingly.
The current study assessed the views and attitudes of health professionals (HPs) regarding factors associated with energy balance-related health behaviours and weight management in breast cancer survivors (BCS) with overweight and obesity. Semi-structured online interviews were conducted with 21 HPs (oncologists, dietitians- nutritionists, physical education instructors, mental health professionals, and nurses) from Attica and Thessaly. Thematic analysis was used to analyse and present the data. Four main themes arose from the data: “The patients’ mental health wellbeing”, “Survivors’ interest in diet and exercise”, “Interdisciplinary collaboration in patient’s care”, and “Maintaining normality”. HPs agreed that weight loss in BCS with overweight and obesity is important, but negative mental health wellbeing is a main barrier to behaviour change. For many BCS their cancer diagnosis is a “teachable” moment for weight management, especially for women of younger age, who are more keen to discuss weight management issues. Essential characteristics that determine/facilitate behavioural change include education, commitment for regular communication, personalised intervention, and interdisciplinary collaboration. According to HPs, future weight loss interventions should take into account BCS’s mental health wellbeing and level of motivation and should provide regular support and education.
Cognitive changes following adjuvant treatment for breast cancer (BC) are well documented particularly following chemotherapy. However, limited studies have examined cognitive and/or language functions in chemotherapy-naive women with BC taking tamoxifen (TAM). While there is some compelling evidence TAM affects cognitive and language domains, language has not been studied beyond semantics (i.e., content of language), which is just one aspect of language. Using ambulatory cognitive assessment, we investigated the trajectory of cognitive and language changes during early period of adjuvant endocrine treatment (tamoxifen) in women with BC at two time periods (pre-treatment and two months after treatment begins).
Participants and Methods:
Four women with BC (mean age = 62.25 years, SD = 8.38) and 18 cognitively healthy age-matched controls (mean age = 59.77, SD = 7.45) completed 3 cognitive tasks using smartphones, during a short time period (5 days) and repeated at two time periods. Symbol search, dot memory and color dots tasks were used to measure the cognitive constructs - processing speed and working memory. Response times were recorded in milliseconds. To determine language ability, language samples were collected at two time periods, where the participants described two stories from two wordless picture books and samples were assessed using core lexicon analyses.
Results:
Wilcoxon-signed rank test was computed to identify cognitive and linguistic changes during early period of TAM administration in women with BC at two time periods. No significant within group or between group differences were seen on the cognitive and language tasks at the two time periods, however, a trend for decline in performance was seen in some BC participants across different tasks.
Conclusions:
This is the first study to our knowledge to use ambulatory cognitive assessment method and study discourse-level language function during this early period (pre-treatment and 2 months post-TAM). Findings from the current study advance our understanding of trajectories of cognition and language changes during the initial course of adjuvant endocrine treatment for women with BC with ER+ tumors. Using a measurement-burst design and ambulatory cognitive assessment, we were able to apply better precision measurement to identify distinct cognitive constructs affected by adjuvant endocrine treatment. In addition, insight into changes in discourse ability are impactful for numerous reasons: (1) better understanding of how adjuvant endocrine therapy impacts communication and (2) discernment into language domains that may require early behavioral intervention.
The Functional Assessment of Cancer Therapy-Cognitive scale (FACT-Cog) is one of the most frequently used patient-reported outcome (PRO) measures of cancer-related cognitive impairment (CRCI) and of CRCI-related impact on quality of life (QOL). Previous studies using the FACT-Cog found that >75% of women with breast cancer (BCa) experience CRCI. Distress tolerance (DT) is a complex construct that encompasses both the perceived capacity (i.e., cognitive appraisal) and the behavioral act of withstanding uncomfortable/aversive/negative emotional or physical experiences. Low DT is associated with psychopathology and executive dysfunction. We previously found that women with BCa with better DT skills reported less CRCI on the FACT-Cog. However, this relationship has not been tested using a performance-based cognitive measure. Therefore, the aims of this study were to: (1) assess the relationship between the FACT-Cog and the Telephone Interview for Cognitive Status (TICS), a performance-based cognitive measure; and (2) test whether the association between DT and CRCI (using the FACT-Cog) was replicated with the TICS.
Participants and Methods:
Participants completed the Distress Tolerance Scale (DTS), the FACT-Cog, and the TICS after undergoing BCa surgery and prior to starting adjuvant therapy [101 women, age >50 years, M(SD)= 61.15(7.76), 43% White Non-Hispanic, 34.4% White Hispanic, 10.8% Black, with nonmetastatic BCa, 55.4% lumpectomy, 36.6% mastectomy; median 29 days post-surgery].
Results:
Although there was a significant correlation between the TICS total score and the FACT-CogQOL subscale (r = 0.347, p < 0.001), the TICS total score was not correlated with scores on the FACT-Cog perceived cognitive impairment (CogPCI), perceived cognitive abilities (CogPCA), or comments from others (CogOth) subscales. However, the TICS memory item, a 10-word list immediate recall task, had a weak statistically significant correlation with CogPCI (r = 0.237, p < 0.032), CogOth (r = 0.223, p < 0.044), and CogPCA (r = 0.233, p < 0.036). Next, the sample was divided based on the participant’s score on TICS memory item (i.e., < vs. > sample mean of 5.09). Results of independent samples t-tests demonstrated significant differences in mean scores for CogPCI, f(80) = -2.09, p = 0.04, Mdt = -7.65, Cohen’s d = 0.483, and CogQOL, f(80) = -2.57, p = 0.01, Mditt = -2.38, Cohen’s d = 0.593. A hierarchical linear regression found that DTS subscale and total scores did not significantly predict performance on the TICS. However, DTS continued to be a significant predictor of poorer FACT-Cog PCI scores while controlling for TICS scores.
Conclusions:
We found a weak relationship between self-reported cognitive impairment and objective cognitive performance (TICS). However, greater self-reported PCI and its impact on QOL was found in participants who scored below the sample mean on a recall task from the TICS. Although perceived ability to tolerate distress continued to predict self-reported PCI on the FACT-Cog, it did not predict overall performance on the TICS. Therefore, responses on the FACT-Cog may be more representative of an individual’s ability to tolerate distress related to perceived CRCI than actual overall cognitive ability or impairment.
This study confirms the effectiveness of pretreatment video-based psychoeducation on stress management and relaxation in reducing depression, anxiety, and uncertainty among patients with breast cancer.
Methods
We conducted a nonrandomized trial with 86 pretreatment patients with breast cancer who were divided equally into intervention and control groups, and stratified according to cancer stages and patient ages. Omitting the excluded participants, 35 intervention group and 36 control group participants were asked to complete the Hospital Anxiety and Depression Scale and Universal Uncertainty in Illness Scale (UUIS) before the psychoeducational intervention (baseline, hereafter “BL “) as well as 1 and 3 months later. Then, a 2 group (intervention and control groups) × 3 time points (BL and 1 and 3 months post-intervention) mixed models repeated measures (MMRM) analysis was implemented.
Results
Analysis confirmed interaction between 2 group × 3 time points for depression, anxiety, and UUIS. Multiple comparisons revealed that each score in the intervention group was significantly lower 1 and 3 months post-intervention compared to BL. Meanwhile, in the control group, the depression score was significantly higher at 3 months post-intervention compared to pre-intervention. The anxiety scores and UUIS of the same group were not significantly different between 1 and 3 months post-intervention. The effect size values 3 months post-intervention were −0.57 for depression, −0.25 for anxiety, and 0.05 for uncertainty.
Significance of results
Pretreatment psychoeducation reduced depression, anxiety, and uncertainty in the intervention group of patients with breast cancer compared to the control group. The effect sizes at 3 months post-intervention were moderate for depression and small for anxiety. These results suggest the effectiveness of psychoeducation for patients with breast cancer, using videos on stress management and relaxation, early at the pretreatment stage.
The issue of linking research and policy is not unique to health care of the elderly; it has been articulated by numerous stakeholder groups, including those with specific diseases, such as breast cancer. A method of enhancing these links is now being systematically addressed in the Canadian Breast Cancer Initiative with the input of women with breast cancer. The Initiative consists of a number of components and demonstrates a model of consumer participation at multiple levels in setting the agenda for research and policy development, thus enhancing accountability in the transfer of research findings into policy. The concept of consumer participation in linking research and policy is transferable to other diseases and other population groups, such as seniors.
A growing number of studies reveal that disruption of the endogenous, circadian (i.e., 24-hour) clock increases the risk for acquiring several diseases, including specific cancers. Significantly more work needs to be done to understand the molecular substrates involved in the mechanistic links between circadian clock disruption and cancer initiation and progression. Of particular complexity remains the contribution of the circadian clock in individual cells during the process of transformation (cancer initiation) versus its function in tumor-surrounding stroma and how this affects the process of tumor progression or metastasis. This chapter reviews some of the basic mechanisms understood to link circadian disruption and cancer at the level of gene expression and metabolism, while highlighting human studies supporting the association between circadian disruption and cancer incidence. In light of what is currently known, tremendous opportunites exist to use circadian approaches for future prevention and treatment strategies in the context of organ-specific cancer.
This is a personal essay about breasts. It focuses on my experiences as a young girl, moving through adolescence to a history of breast cancer in my family, including my mother’s breast cancer diagnosis. As a physician, patient, and wife, I reflect on the choices that I have to make and what this means for my identity as a woman and mother.
Although palliative care units treat patients with various comorbidities, there are no reports of patients with obsessive-compulsive disorder (OCD).
Methods
The treatment and care of a breast cancer patient with OCD are presented.
Results
A woman in her 40s was admitted to the palliative care unit for terminal breast cancer. She spent most of the day cleaning the bath and bed areas, ignoring efforts to restrain her actions by the staff. After being diagnosed with OCD, the above symptoms improved through the coordinated action of the staff and medication.
Significance of results
This is the first report of the diagnosis and treatment of a patient with OCD in a palliative care unit. Early psychiatric diagnosis and subsequent staff response contributed to improvement in the patient’s quality of life.
The relationship between erythrocyte membrane n-3 PUFA and breast cancer risk is controversial. We aimed to examine the associations of erythrocyte membrane n-3 PUFA with odds of breast cancer among Chinese women by using a relatively large sample size. A case–control study was conducted including 853 newly diagnosed, histologically confirmed breast cancer cases and 892 frequency-matched controls (5-year interval). Erythrocyte membrane n-3 PUFA were measured by GC. Logistic regression and restricted cubic spline were used to quantify the association between erythrocyte membrane n-3 PUFA and odds of breast cancer. Erythrocyte membrane α-linolenic acid (ALA), docosapentaenoic acid (DPA) and total n-3 PUFA were inversely and non-linearly associated with odds of breast cancer. The OR values (95 % CI), comparing the highest with the lowest quartile (Q), were 0·57 (0·43, 0·76), 0·43 (0·32, 0·58) and 0·36 (0·27, 0·49) for ALA, DPA and total n-3 PUFA, respectively. Erythrocyte membrane EPA and DHA were linearly and inversely associated with odds of breast cancer ((EPA: ORQ4 v. Q1 (95 % CI) = 0·59 (0·45, 0·79); DHA: ORQ4 v. Q1 (95 % CI) = 0·50 (0·37, 0·67)). The inverse associations were observed between ALA and odds of breast cancer in postmenopausal women, and between DHA and oestrogen receptor+ breast cancer. This study showed that erythrocyte membrane total and individual n-3 PUFA were inversely associated with odds of breast cancer. Other factors, such as menopause and hormone receptor status, may warrant further investigation when examining the association between n-3 PUFA and odds of breast cancer.
Inflammation and immune evasion are major key players in breast cancer (BC) progression. Recently, the FDA approved the use of anti-programmed death-ligand 1 antibody (anti-PD-L1) and phosphoinositide 3-kinase (PI3K) inhibitors against aggressive BC. Despite the paradigm shift in BC treatments, patients still suffer from resistance, recurrence and serious immune-related adverse events. These obstacles require unravelling of the hidden molecular contributors for such therapy failure hence yielding therapeutics that are at least as efficient yet safer. Inflammasome pathway is activated when the pattern recognition receptor senses danger signals (danger-associated molecular patterns) from damagedRdying cells or pathogen-associated molecular patterns found in microbes, leading to secretion of the active pro-inflammatory cytokines interleukin-1β (IL-1β) and interleukin-18 (IL-18). It has been shown throughout numerous studies that inflammasome pathway enhanced invasion, metastasis, provoked BC progression and therapy resistance. Additionally, inflammasomes upregulated the proliferative index ki67 and enhanced PD-L1 expression leading to immunotherapy resistance. IL-1β contributed to significant decrease in oestrogen receptor levels and promoted BC chemo-resistance. High levels of IL-18 in sera of BC patients were associated with worst prognosis. Stimulation of purinergic receptors and modulation of adipokines in obese subjects activated inflammasomes that evoked radiotherapy resistance and BC progression. The micro RNA miR-223-3p attenuated the inflammasome over-expression leading to lowered tumour volume and lessened angiogenesis in BC. This review sheds the light on the molecular pathways of inflammasomes and their impacts in distinct BC subtypes. In addition, it highlights novel strategies in treatment and prevention of BC.
Breast cancer is a high-risk disease with a high mortality rate among women. Chemotherapy plays an important role in the treatment of breast cancer. However, chemotherapy eventually results in tumours that are resistant to drugs. In recent years, many studies have revealed that the activation of Wnt/β-catenin signalling is crucial for the emergence and growth of breast tumours as well as the development of drug resistance. Additionally, drugs that target this pathway can reverse drug resistance in breast cancer therapy. Traditional Chinese medicine has the properties of multi-target and tenderness. Therefore, integrating traditional Chinese medicine and modern medicine into chemotherapy provides a new strategy for reversing the drug resistance of breast tumours. This paper mainly reviews the possible mechanism of Wnt/β-catenin in promoting the process of breast tumour drug resistance, and the progress of alkaloids extracted from traditional Chinese medicine in the targeting of this pathway in order to reverse the drug resistance of breast cancer.
