Meta-analysis of the prevalence of depression among breast cancer survivors in Iran: an urgent need for community supportive care programs

Global prevalence and factors associated with preoperative depression in women undergoing breast surgery: a meta-analysis and meta-regression

PURPOSE

Depression is one of the main psychological responses experienced by patients with breast cancer perioperatively. Therefore, this review aimed to synthesize the prevalence rate of depression preoperatively among patients with breast cancer.

METHODS

Six databases were searched for published articles, which recruited female patients aged 18 years and above, diagnosed with breast cancer and planned for breast surgery. Grey literatures were searched from ProQuest Theses and Dissertations, Science.gov and CogPrints. Studies published in English from the inception of databases to January 2023 were considered. Two reviewers screened, extracted, and appraised the data independently. Joanna Briggs Institute data collection form was used for data collection. Hoy's Risk of Bias Tool was utilized to assess the individual study's quality. Review Manager 5.4 software was utilized for meta-analysis. Subgroup analyses were conducted to explore the reasons for any heterogeneity. Publication bias was evaluated by Egger's test and funnel plot.

RESULTS

Twenty studies involving 32,143 patients with breast cancer were included. Meta-analyses revealed an overall preoperative prevalence of 30% among all studies. Subgroup analyses showed that studies conducted in the Middle East and North Africa used purposive sampling, with patients undergoing mastectomy and lumpectomy and with moderate risk of bias reported higher prevalence of preoperative depression (54%, 44%, 40%, and 49%, respectively) as compared to other respective subgroups.

CONCLUSION

The high prevalence of preoperative depression among women with breast cancer indicated the need for health care professionals to provide more psychological support to them.

The prevalence of anxiety and depression in cancer around the world: An overview of systematic reviews evaluating 128 meta-analyses

BACKGROUND

This overview of systematic reviews with meta-analysis summarized the prevalence of anxiety and depression in different types of tumors around the world.

METHODS

The quality of reviews was assessed. The degree of overlap between reviews was calculated. The regional prevalence of anxiety and depression was shown in the main text based on the World Health Organization regions.

RESULTS

Twenty-five reviews including 128 meta-analyses of interest were selected. The pooled prevalence of anxiety in breast tumors was in Africa (19 %), the Americas (38 %), Eastern Mediterranean (56 %), Europe (38 %), South-East Asia (42 %), and Western Pacific (26 %). The pooled prevalence of depression in breast tumors was in Africa (40 %), the Americas (23-25 %), Eastern Mediterranean (49-51 %), Europe (27-29 %), South-East Asia (23-33 %), Western Pacific (29 %). The pooled prevalence of depression in digestive tumors was in the Americas (4-44 %), Eastern Mediterranean (42 %), Europe (20-27 %), South-East Asia (66 %), and Western Pacific (24-40 %). The pooled national prevalence of anxiety and depression was mainly evaluated in China and Iran.

LIMITATIONS

Important methodological issues were identified. For example, no reviews judged the certainty of evidence.

CONCLUSIONS

The Eastern Mediterranean region showed the highest prevalence of anxiety and depression for breast tumors. The South-East Asian region showed the highest prevalence of depression for digestive tumors. In these regions, many countries are considered low-income and middle-income countries. Further research funding would help increase the investigation on this topic, which may allow the development of preventive strategies that reduce the prevalence of anxiety and depression.

Mental Health Care Utilization and its Barriers among Iranian Breast Cancer Survivors: A Cross-sectional Study

Background

Depression and anxiety are common comorbidities complicating the care of breast cancer patients, but many patients do not receive the needed care. We aimed to assess utilization of mental health care and its barriers in breast cancer survivors.

Methods

This cross-sectional study was conducted on 311 patients with breast cancer, in Iran, November 2021 to March 2022. Perceived need and utilization of mental health care and barriers to service utilization were measured based on self-report. Depression, Anxiety, and Stress Scale-21 and Multidimensional Scale of Perceived Social Support were used to assess depression, anxiety, and stress as well as social support, respectively. A linear and logistic regression model was used to analyze the data using SPSS version 22. A P-value less than 0.05 was considered statistically significant.

Results

70.1% of the participants perceived need for mental health care, 28.0% of them had used mental health services, and 72% were classified as having unmet needs. The most common perceived barrier to service use was patients' self-adequacy. The prevalence of extremely severe levels of depression, anxiety, and stress was 14.8%, 23.5%, and 10.6%. Also, 48.6%, 78.5%, and 75.6% of patients received a high level of social support from friends, family, and significant others.

Conclusion

Findings highlight a substantial unmet need for mental health care and low utilization of mental health services among breast cancer survivors. Given the significant prevalence of depression, anxiety, and stress in this population, it is imperative to address the underutilization of mental health services and to further examine the barriers preventing patients from seeking the care they require.

Effect of alcohol consumption on breast cancer: probabilistic bias analysis for adjustment of exposure misclassification bias and confounders

PURPOSE

This study was conducted to evaluate the effect of alcohol consumption on breast cancer, adjusting for alcohol consumption misclassification bias and confounders.

METHODS

This was a case-control study of 932 women with breast cancer and 1000 healthy control. Using probabilistic bias analysis method, the association between alcohol consumption and breast cancer was adjusted for the misclassification bias of alcohol consumption as well as a minimally sufficient set of adjustment of confounders derived from a causal directed acyclic graph. Population attributable fraction was estimated using the Miettinen's Formula.

RESULTS

Based on the conventional logistic regression model, the odds ratio estimate between alcohol consumption and breast cancer was 1.05 (95% CI: 0.57, 1.91). However, the adjusted estimates of odds ratio based on the probabilistic bias analysis ranged from 1.82 to 2.29 for non-differential and from 1.93 to 5.67 for differential misclassification. Population attributable fraction ranged from 1.51 to 2.57% using non-differential bias analysis and 1.54-3.56% based on differential bias analysis.

CONCLUSION

A marked measurement error was in self-reported alcohol consumption so after correcting misclassification bias, no evidence against independence between alcohol consumption and breast cancer changed to a substantial positive association.

Prevalence and severity of anxiety and depression in Chinese patients with breast cancer: a systematic review and meta-analysis

Context

Anxiety/depression in breast cancer (BC) is common around the world, and Chinese BC patients should not be ignored. The prevalence of anxiety and depression among BC patients are various in different regions of China, but no clear summarization has been made.

Purpose

This meta-analysis aimed to evaluate the prevalence and severity of anxiety and depression among breast cancer (BC) patients in China.

Methods

A literature search on PubMed, Web of Science, Embase, CINAHL, Scopus, PsycINFO, Cochrane database library, CNKI, Wanfang, and SinoMed was conducted up to 29 December 2021. The effect size (ES) or standard mean difference (SMD) and the corresponding 95% confidence intervals (CIs) for the prevalence and severity of anxiety/depression were calculated using the STATA 12.0 software.

Results

A total of 63 identified studies were included, containing a total of 53,513 Chinese women confirmed breast cancer. The results showed a high pooled prevalence of anxiety (38%, 95% CI, 27-50%, I2 = 99.4%, p < 0.001) and depression (38%, 95% CI, 33-44%, I2 = 99.2%, p < 0.001) among Chinese BC patients. Moreover, both anxiety (SMD = 0.30, 95% CI, 0.08-0.53, I2 = 91.6%, p < 0.001) and depression (SMD = 0.25, 95% CI, -0.05-0.55, I2 = 95.3%, p < 0.001) in BC patients were more serious than those in healthy controls, but not significantly different from patients with other diseases. Specifically, among the six regions included, the prevalence of anxiety and depression were both the highest in Northeast China, obviously superior than the second-highest region.

Conclusion

The study showed high levels of anxiety and depression among BC patients in China, especially those in the northeast. Clinicians and researchers should pay attention to the psychological problems of patients with breast cancer and regard it as one of the important prognostic outcomes of patients.

How does social media use influence the mental health of pancreatic cancer patients: a chain mediating effect of online social support and psychological resilience

Background

Pancreatic cancer is an extremely malignant disease that poses a serious threat to the mental health of patients. Many cancer patients now use social media for online social support. However, the impact of social media on mental health is currently inconsistent in the academic community. Therefore, this study aimed to examine the mediating effects of online social support and psychological resilience in the relationship between social media use and mental health of pancreatic cancer patients.

Methods

Four hundred and twenty-five valid questionnaires were collected through convenience sampling. All data were processed using SPSS 26.0 and AMOS 26.0. We examine the influence relationships among latent variables by constructing a structural equation model. Then SPSS Process Macro was used to test the chain mediating effect of the model.

Results

The results showed that (1) anxiety situations occurred in 22.2% of participants (N = 94), while the incidence of depression was 20.2% (N = 86). (2) Social media use positively influenced online social support (β = 0.990, p < 0.001), psychological resilience (β = 0.504, p < 0.001), and mental health (β = 0.330, p < 0.001); online social support positively influenced psychological resilience (β = 0.535, p < 0.001) and mental health (β = 0.354, p < 0.001); psychological resilience significantly and positively influenced mental health (β = 0.243, p < 0.001). (3) The chain mediating effect of online social support and psychological resilience was significant at 0.253 with a confidence interval of [0.178, 0.340].

Conclusion

Pancreatic cancer patients in China are exposed to a high burden of anxiety and depression, which requires urgent attention. Meanwhile, online social support and psychological resilience played a chain mediating role between social media use and mental health (anxiety and depression), and our results provide new insights and ways to support the mental health improvement of pancreatic cancer patients.

Breast cancer survivors-supportive care needs: systematic review

OBJECTIVES

To achieve optimal survival care outcomes, all healthcare services must be tailored to patients' specific needs, preferences and concerns throughout the survival period. This study aimed to identify supportive care needs from the point of view of breast cancer survivors.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting systematic reviews, a comprehensive search of PubMed, Web of Science and Scopus was performed. The inclusion criteria were studies published from inception to the end of January 2022, covering all stages of breast cancer. The exclusion criteria were mixed-type studies relating to cancer, such as case reports, commentaries, editorials and systematic reviews, as well as studies that assessed patients' needs during cancer treatment. Two quality assessment tools were used for the qualitative and quantitative studies.

RESULTS

Of the 13 095 records retrieved, 40 studies, including 20 qualitative and 20 quantitative studies, were retained for this review. Survivors' supportive care needs were classified into 10 dimensions and 40 subdimensions. The most frequently mentioned supportive care needs of survivors were psychological/emotional needs (N=32), health system/informational needs (N=30), physical and daily activities (N=19), and interpersonal/intimacy needs (N=19).

CONCLUSIONS

This systematic review highlights several essential needs for breast cancer survivors. Supportive programmes should be designed in order to take into consideration all aspects of these needs, particularly psychological, emotional and informational needs.

Association of Chinese herbal medicine use with the depression risk among the long-term breast cancer survivors: A longitudinal follow-up study

Background

Breast cancer patients are at elevated risk of depression during treatment, thus provoking the chance of poor clinical outcomes. This retrospective cohort study aimed to investigate whether integrating Chinese herbal medicines citation(CHM) into conventional cancer therapy could decrease the risk of depression in the long-term breast cancer survivors.

Methods

A cohort of patients aged 20–70 years and with newly diagnosed breast cancer during 2000–2008 was identified from a nationwide claims database. In this study, we focused solely on survivors of breast cancer at least1 year after diagnosis. After one-to-one matching for age, sex, and baseline comorbidities, breast cancer patients who received (n = 1,450) and did not receive (n = 1,450) CHM treatment were enrolled. The incidence rate and hazard ratio citation(HR) for depression between the two groups was estimated at the end of 2012. A Cox proportional hazard model was constructed to examine the impact of the CHM use on the risk of depression.

Results

During the study period, the incidence rate of depression was significantly lower in the treated cohort than in the untreated cohort [8.57 compared with 11.01 per 1,000 person-years citation(PYs)], and the adjusted HR remained significant at 0.74 (95% CI 0.58–0.94) in a Cox proportional hazards regression model. The corresponding risk further decreasing to 43% among those using CHM for more than 1 year.

Conclusion

Finding from this investigation indicated that the lower risk of depression observed in breast cancer patients treated with CHM, suggesting that CHM treatment should be considered for disease management toward breast cancer. Yet, the optimal administered dose should be determined in further clinical trials.

The prevalence of anxiety and depression and its association with coping strategies, supportive care needs, and social support among women with breast cancer

PURPOSE

Diagnosis of breast cancer and its treatment dramatically affects women's psychological health. This study investigated the prevalence of depression and anxiety and their related factor in breast cancer women.

METHODS

We conducted a cross-sectional study with a sample of 120 women with breast cancer in Zahedan, Iran, 2020. Data were collected using instruments included: Hospital Anxiety and Depression Scale (HADS), Supportive Care Needs Survey (SCNS-SF34), Multidimensional Scale of Perceived Social Support (MSPSS), The adjustment to illness measurement inventory for Iranian women with breast cancer (AIMI-IBC). We analyzed the data using the ANOVA, independent sample t-test, Kruskal Wallis, Mann-Whitney U test, Pearson's and Spearman's correlation coefficients.

RESULTS

The prevalence of depression and anxiety in women with breast cancer was 66.6% and 60%, respectively. A significant positive correlation was found between anxiety and depression and unmet psychological needs, care/support needs, and emotional turmoil coping strategy, while reasonable efforts and avoidance coping strategies and adjusting to disease were negatively correlated with anxiety and depression. Also, linear regression results indicated unmet psychological needs, emotional turmoil coping strategy, and a high level of depression predicted a high anxiety level. A lower level of depression was indicated by reasonable efforts strategy and less level of anxiety.

CONCLUSIONS

Women with breast cancer reported a high level of depression and anxiety in Zahedan, and clinicians should pay more attention to these patients' psychological distress. Resolving the unmet need of patients, increasing social support, and using the right coping strategy have an essential role in breast cancer women's psychological distress control.

Body image, internalized stigma and enacted stigma predict psychological distress in women with breast cancer: A serial mediation model

AIMS

To investigate the roles of total stigma, enacted stigma, and internalized stigma in the prediction of psychological distress among breast cancer patients, and to evaluate the mediating effect of body image in this process.

DESIGN

Cross-sectional.

METHODS

Between Oct-2014 to May-2015, a cross-sectional study was conducted with participation of 223 patients from three cancer centres located in Tehran, Iran. The study variables were assessed using the stigma scale for chronic illnesses 8-item version (SSCI-8), body image scale (BIS), and depression anxiety stress scale (DASS-21). Structural equation modelling using MLR estimator was employed based on the two-step procedure to validate both the full measurement models and the structural models. Five models were tested to determine predictability of all stigma constructs for psychological distress, including stress, anxiety, and depression, through the mediation of body image. Three equivalent models were further examined to re-evaluate the direction of the relationships.

RESULTS

Psychological distress and body image were largely predicted by total stigma, enacted stigma, and internalized stigma. The effect of stigma on psychological distress was mediated through body image. In a serial mediation model, the significance of the pathway of enacted stigma > internalized stigma > body image > psychological distress was confirmed. The serial model in which internalized stigma precedes body image was also supported by the equivalent models.

CONCLUSION

Stigma has been identified as a major source of psychological distress among women with breast cancer. Enacted stigma not only psychologically disturbs the patients but also triggers a chain of other identity transformations (i.e. internalization of stigma and distortion of body image), their ultimate result being a full-blown psychological distress.

IMPACT

Both enacted and internalized stigma distorts breast cancer patients' perception of their body image, which in turn renders them psychologically distressed. The serial process of enacted stigma, internalized stigma, and body image plays an important role in perpetuating distress in these patients. To break this chain of psychological consequences and for interventions to have a greater impact on overall well-being of patients, the effect of enacted stigma on distress via the sequence of two mediators needs to be specifically targeted at each stage.

Depression and Anxiety in Patients With Cancer: A Cross-Sectional Study

Objectives

Depression and anxiety persist in cancer patients, creating an additional burden during treatment and making it more challenging in terms of management and control. Studies on the prevalence of depression and anxiety among cancer patients in the Middle East are limited and include many limitations such as their small sample sizes and restriction to a specific type of cancer in specific clinical settings. This study aimed to describe the prevalence and risk factors of depression and anxiety among cancer patients in the inpatient and outpatient settings.

Materials and Methods

A total of 1,011 patients (399 inpatients and 612 outpatients) formed the study sample. Patients’ psychological status was assessed using the Hospital Anxiety and Depression Scale (HADS), the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder 7-item (GAD-7) scale. The prevalence rate of depressive and anxious symptomatology was estimated by dividing the number of patients who exceeded the borderline score: 10 or more for each subscale of the HADS scale, 15 or more for the GAD-7 scale, and 15 or more in the PHQ-9 by the total number of the patients. Risk factors were identified using logistic regression.

Results

The prevalence of depressive and anxious symptomatology among all patients was 23.4% and 19.1–19.9%, respectively. Depressive symptomatology was more prevalent across patients who were hospitalized (37.1%) compared with patients in the outpatient setting (14.5%) (p < 0.001). Similarly, anxious symptomatology was more prevalent in the inpatient setting (p < 0.001). In the inpatient setting, depressive symptomatology was more prevalent among patients with bladder cancer, while severe anxious symptomatology was more prevalent across patients with lung cancer. In the outpatient setting, depressive and anxious symptomatology was more prevalent among breast and prostate cancer patients, respectively. Despite that, around 42.7% and 24.8% of the patients, respectively, reported that they feel anxious and depressed, and only 15.5% of them were using medications to manage their conditions.

Conclusion

Our study findings demonstrated a higher prevalence of depressive and anxious symptomatology in the inpatient setting and advanced disease stages. In addition, the underutilization of antidepressant therapy was observed. There is a need to consider mental disorders as part of the treatment protocol for cancer patients. Enhanced clinical monitoring and treatment of depression and anxiety of cancer patients are required.

Feasibility of modified radical mastectomy with nipple-areola preservation combined with stage I prosthesis implantation using air cavity-free suspension hook in patients with breast cancer

Background

Mastoscopic surgery is proven to have lower incidence of postoperative complications and better postoperative recovery than traditional breast cancer surgery. This study aimed to examine the feasibility of mastoscopic modified radical mastectomy (MRM) with skin nipple-areola preservation under air cavity-free suspension hook and stage I silicone prosthesis implantation (SMALND) compared with routine MRM.

Methods

This was a retrospective study of patients who underwent MRM for breast cancer at the Shengjing Hospital Affiliated to China Medical University between January 1, 2019, and June 30, 2019. Surgical outcomes, complications, satisfaction, and quality of life (Functional Assessment of Cancer Therapy-Breast [FACT-B] [Chinese version]) were compared between the two groups.

Results

A total of 87 patients were enrolled, with 30 underwent SMALND and 57 underwent routine MRM. The intraoperative blood loss in the SMALND group was lower than in the control group (165.3±44.1 vs. 201.4±52.7 ml, P=0.001), the operation time was longer (220.5±23.9 vs. 155.6±9.2 min, P<0.001), daily axillary drainage volume was smaller (20.2±3.6 vs. 24.1±3.0 ml, P<0.001), daily subcutaneous drainage volume was smaller (15.5±2.3 vs. 19.3±3.5 ml, P<0.001), the discharge time was shorter (7.5±1.6 vs. 9.0±1.8 days, P<0.001), and FACT-B scores were higher (83.8±5.6 vs. 72.1±4.6, P<0.001). The overall satisfaction was higher in the SMALND group than in the controls (76.7% vs. 54.4%, P=0.041). Compared with the controls, the occurrence rates of nipple and flap necrosis, upper limb edema, and paraesthesia in the SMALND group were lower within 6 months (all P<0.05).

Conclusions

Compared with traditional MRM, SMALND had better surgical outcomes, higher satisfaction, higher quality of life, and lower complication rates.

Posttreatment Anxiety, Depression, Sleep Disorders, and Associated Factors in Women Who Survive Breast Cancer

Objective

Breast Cancer Survivors (BCSs) experience negative effects on their physical and mental health, including sleep disorders, after the completion of treatment and over the whole spectrum of survival. The aim of this study was to investigate the levels of posttreatment anxiety, depression, and sleep disorders exhibited by women who have survived breast cancer.

Methods

A descriptive, cross-sectional study was conducted with a population of 170 BCSs, who were monitored as outpatients by two surgical departments of a central Athens hospital for between one and five-5 years after completing their therapy. The data were collected between November 2019 and March 2020 and included demographic and clinical characteristics, as well as the Athens Insomnia Scale to measure sleep disorders and the Hospital Anxiety and Depression Scale to assess the incidence of mental disorders.

Results

The majority of the patients were aged 61-70 years (41.4%), married (56.9%), with two children (56.3%), and graduates of higher education (41.8%). Of the total population, 53.5% had sleep disorders, 29.4% anxiety, and 18.2% depression. Insomnia had a moderately positive correlation with both anxiety and depression (r = 0.598, P < 0.001 and r = 0.584, P < 0.001, respectively), while a strongly positive correlation was found between depression and anxiety (r = 0.683, P < 0.001). Sleep disorders were associated with factors such as profession (P < 0.001), income (P = 0.01), the number of minor children (P = 0.021), and the number of pathological problems (P = 0.003); anxiety was related to the number of minor children (P = 0.008) and the use of drug therapy to treat mental disorders (P = 0.038); while for depression, the relevant factors were the duration of treatment (P = 0.029), the number of minor children (P < 0.001), the use of medication for treatment of mental disorders (P = 0.008), and sleep disorders (P = 0.003).

Conclusions

Women who have survived breast cancer in Greece show a high rate of anxiety and depression related to the disease, as well as sleep problems that are partly associated with their psychological status, but are also affected by parameters such as income, type of profession, and the presence of minor children in the household.

Patient-centred communication for women with breast cancer: Relation to body image perception

AIMS AND OBJECTIVES

This study aimed to determine the predictive values of patient-centred communication (PCC) and patient's characteristics on the body image (BI) perception in postmastectomy patients.

BACKGROUND

Patient-centred communication has been touted as a means of addressing BI issues, especially for postmastectomy patients.

DESIGN AND METHODS

This predictive correlational study was conducted on 275 surgically treated breast cancer patients admitted to the Oncology Departments of two hospitals in Tabriz, Iran. These patients were selected using a convenience sampling method. The Body Image after Breast Cancer Questionnaire (BIBCQ) and patient-centred communication questionnaire (PCCQ) were used for collecting the data. Descriptive and inferential statistics were applied to the data. Reporting was in accordance with the STROBE guideline.

RESULTS

A multivariable model significantly predicted BI perception in participants using surgery type and time elapsed following surgery. Participants' limitations were significantly affected by surgery type and participants' perception of the nurses' PCC skills. Arm concern was significantly affected by surgery type and nurses' PCC skills.

CONCLUSION

Patient-centred skills in nurse-patient communication are critical for resolving BI difficulties such as arm concerns and limitations regarding the disease and its treatment.

RELEVANCE TO CLINICAL PRACTICE

Patient-centred communication skills can be taught nurses in the clinical setting to help alleviate patients' BI problems.

Factor structure and reliability of Persian version of hospital anxiety and depression scale in patients with breast cancer survivors

Introduction

Anxiety and depression are significant concerns in breast cancer patients, and it may remain for a long term after primary treatments. The hospital anxiety and depression scale (HADS) is widely used to measure depressive and anxiety symptoms in clinical practices. The purpose of this study was to assess the psychometric properties of the Persian version of this scale in Iranian breast cancer survivors.

Methods

A total of 305 patients with breast cancer, refered to Cancer Hospital in northen Iran and completed the primary treatments were enrolled in. All patients responded to a 14-item HADS. We performed confirmatory factor analysis (CFA) to examine the factor structure of HADS and the item-scale analysis in order to estimate the item reliability and consider the Cronbach’s alpha as a measure of internal consistency.

Results

With a threshold of ≥8, the prevalence of anxiety and depression symptoms (moderate/severe) was 78.9 and 66.9%, respectively. The Cronbach’s alpha coefficients for anxiety and depression were 0.81 and 0.78, respectively. The CFA confirmed the two-factor structure model for HADS, indicating a good fitting summary indexes (χ2/df = 2.83, NFI = 0.88, RFI = 0.82, IFI = 0.92, CFI = 0.92, and RMSEA = 0.078).

Conclusion

The CFA and item reliability analysis have indicated an excellent psychometric property of the Persian version of HADS to measure depressive and anxiety symptoms in breast cancer survivors. Thus, HADS is a useful screening tool to identify post-breast cancer anxiety and depressive disorders.

Global and regional geographical prevalence of depression in gastric cancer: a systematic review and meta-analysis

BACKGROUND

Substantial uncertainty exists about the prevalence of depression in patients with gastric cancer. We aimed to summarise the global and regional pooled prevalence of depression among patients with gastric cancer.

METHOD

Up to February 2020, we searched PubMed/MEDLINE, Embase, Scopus, Web of science (ISI) and PsychINFO to identify published studies on the prevalence of depression among patients with gastric cancer. The study selection procedure was in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We estimated the prevalence of depression in gastric cancer patients using a random-effect pooled estimate analysis approach with subgroup analysis based on WHO regions, and methods of depression measurement.

RESULTS

Totally, we retrieved 3781 studies from the previously mentioned databases, of which 18 (12 cross-sectional and 6 cohort studies in design) met the eligibility criteria, which were published from 2001 to 2017 in different regions. The total sample size of the included studied contained 4709 patients with gastric cancer, of which 1885 cases were diagnosed with depression. The pooled prevalence of depression among gastric cancer patients was 37%(95% CI: 26% to 48%). Subgroup analysis showed that the highest prevalence of depression was in Eastern Mediterranean (pooled prevalence=42%; 95% CI: 18% to 65%) followed by the Western Pacific region (pooled prevalence=40%;95% CI: 26% to 54%). The results indicated a significant heterogeneity (I ²=98.8%,P<0.05).

CONCLUSION

Our findings indicated that depression is high among gastric cancer patients. The findings suggest health authorities to provide specially designed social and psychological supportive care services, including screening for depression, among such patients.

Prevalence of Severe Depression in Iranian Women with Breast Cancer: A Meta-Analysis

BACKGROUND

Breast cancer is one of the most common cancers in women and has mental and emotional effects, which lead to a decline in their quality of life. This study is aimed at determining the prevalence of severe depression in Iranian women with breast cancer.

METHODS

This meta-analysis study was conducted at Zabol University of Medical Sciences in 2019. Seven electronic databases were searched and evaluated for original research papers published on the prevalence of severe depression in Iranian women with breast cancer. Finally, 13 articles were selected and analyzed via Comprehensive Meta-Analysis software.

RESULTS

Overall, the prevalence of severe depression in Iranian women with breast cancer was 11% (95% CI (7.2, 16.5)). The highest prevalence was 44% in Tehran City in 2015 (95% CI (31, 57.9)), and the lowest prevalence was 0.8% in Qom City in 2017 (95% CI (0.01, 6.2)). A significant statistical correlation was observed between the prevalence of severe depression and sample size (p < 0.05).

CONCLUSION

According to the results of this study, the prevalence of severe depression affects more than one-tenth of women with breast cancer.
