Incidence of primary breast cancer in Iran: Ten-year national cancer registry data report

Relative risk of childhood and adolescence cancer in Iran: spatiotemporal analysis from 1999 to 2016

OBJECTIVE

Cancer is the third leading cause of death in the world with increasing trends in Iran. The study of epidemiology, trend, and geospatial distribution of pediatric cancers provides important information for screening as well as early detection of cancer and policy making. We aimed to assess the spatio-temporal disparity of childhood and adolescence cancer risk among provinces of Iran.

METHODS

In this retrospective study, we estimated geospatial relative risk (RR) of childhood cancer in provinces of Iran using data from 29198 cases. We used BYM and its extended spatiotemporal model in Bayesian setting. This hierarchical model takes spatial and temporal effects into account in the incidence rate estimation simultaneously.

RESULTS

The relative risk of cancer was > 1 for 45% of the provinces, where 27% of provinces had significantly ascending trend. North Khorasan, Yazd and Qazvin provinces had the highest risk rates while Sistan-Baluchistan province showed the lowest risk of cancer. However, the differential trends was highest in Sistan-Baluchistan, Bushehr, Hormozgan, and Kohgilouyeh-Boyerahmad. Both the point estimate and the trend of risk was high in Tehran.

CONCLUSION

The geographic pattern and trend of cancer in children seems to be different from that in adults that urges further studies. This could lead to increased health system capacity and facilitate the access to effective detection, research, care and treatment of childhood cancer.

Decomposing socioeconomic disparity in the utilization of screening mammography: A cross-sectional analysis from the RaNCD cohort study

We aimed to examine the degree of socioeconomic inequality in screening mammography among Kurdish women of Iran. Data from the Ravansar Non-Communicable Diseases (RaNCD) Cohort Study were used. A total of 3,219 women aged 35-65 years were studied. The concentration index (CIn) was used to measure the magnitude of socioeconomic-related inequalities in screening mammography. Decomposition analysis was employed to calculate the contribution of each explanatory variable to the observed inequality. The participation rate for screening mammography was 19.7%. The CIn of screening mammography was 0.142 (95% CI: 0.0197, 0.0656), indicating that screening mammography is more concentrated among high-SES women. Socioeconomic status, education level and area of residence were the main contributors to the observed inequality, respectively. We found a pro-rich inequality in screening mammography among Iranian Kurdish women. For mitigating socioeconomic inequality in screening mammography policymakers should focus more on the poor and rural communities.

Development and evaluation of a customized checklist to assess the quality control of disease registry systems of Tehran, the capital of Iran in 2021

BACKGROUND

Clinical registries facilitate medical research by providing 'real data'. In the past decade, an increasing number of disease registry systems (DRS) have been initiated in Iran. Here, we assessed the quality control (QC) of the data recorded in the DRS established by Shahid Beheshti University of Medical Sciences in Tehran, the capital city of Iran, in 2021.

METHODS

The present study was conducted in two consecutive qualitative and quantitative phases and employed a mixed-method design. A checklist containing 23 questions was developed based on a consensus reached following several panel group discussions, whose face content and construct validities were confirmed. Cronbach's alpha was calculated to verify the tool's internal consistency. Overall, the QC of 49 DRS was assessed in six dimensions, including completeness, timeliness, accessibility, validity, comparability, and interpretability. The seventy percent of the mean score was considered a cut-point for desirable domains.

RESULTS

The total content validity index (CVI) was obtained as 0.79, which is a reasonable level. Cronbach's alpha coefficients obtained showed acceptable internal consistency for all of the six QC domains. The data recorded in the registries included different aspects of diagnosis/treatment (81.6%) and treatment quality requirements outcomes (12.2%). According to the acceptable quality cut-point, out of 49 evaluated registries, 48(98%), 46(94%), 41(84%), and 38(77.5%), fulfilled desirable quality scores in terms of interpretability, accessibility, completeness, and comparability, however, 36(73.5%) and 32(65.3%) of registries obtained the quality requirement for timeliness and validity, respectively.

CONCLUSION

The checklist developed here, containing customized questions to assess six QC domains of DRSs, provided a valid and reliable tool that could be considered as a proof-of-concept for future investigations. The clinical data available in the studied DRSs fulfilled desirable levels in terms of interpretability, accessibility, comparability, and completeness; however, timeliness and validity of these registries needed to be improved.

National and subnational burden of female and male breast cancer and risk factors in Iran from 1990 to 2019: results from the Global Burden of Disease study 2019

BACKGROUND

Breast cancer (BC) is one of the most burdensome cancers worldwide. Despite advancements in diagnostic and treatment modalities, developing countries are still dealing with increasing burdens and existing disparities. This study provides estimates of BC burden and associated risk factors in Iran at the national and subnational levels over 30 years (1990-2019).

METHODS

Data on BC burden for Iran were retrieved from the Global Burden of Disease (GBD) study from 1990 to 2019. GBD estimation methods were applied to explore BC incidence, prevalence, deaths, disability-adjusted life years (DALYs), and attributable burden to risk factors based on the GBD risk factors hierarchy. Moreover, decomposition analysis was performed to find the contribution of population growth, aging, and cause-specific incidence in the total incidence change. Age-standardized rates (per 100,000 population) and 95% uncertainty intervals (UI) were reported based on sex, age, and socio-demographic index (SDI).

RESULTS

Age-standardized incidence rate (ASIR) increased from 18.8 (95% UI 15.3-24.1)/100,000 in 2019 to 34.0 (30.7-37.9)/100,000 in 2019 among females and from 0.2/100,000 (0.2-0.3) to 0.3/100,000 (0.3-0.4) among males. Age-standardized deaths rate (ASDR) increased slightly among females from 10.3 (8.2-13.6)/100,000 in 1990 to 11.9 (10.8-13.1)/100,000 in 2019 and remained almost the same among males-0.2/100,000 (0.1-0.2). Age-standardized DALYs rate also increased from 320.2 (265.4-405.4) to 368.7 (336.7-404.3) among females but decreased slightly in males from 4.5 (3.5-5.8) to 4.0 (3.5-4.5). Of the 417.6% increase in total incident cases from 1990-2019, 240.7% was related to cause-specific incidence. In both genders, the BC burden increased by age, including age groups under 50 before routine screening programs, and by SDI levels; the high and high-middle SDI regions had the highest BC burden in Iran. Based on the GBD risk factors hierarchy, high fasting plasma glucose (FPG) and alcohol were estimated to have the most and the least attributed DALYs for BC among females, respectively.

CONCLUSIONS

BC burden increased from 1990 to 2019 in both genders, and considerable discrepancies were found among different provinces and SDI quintiles in Iran. These increasing trends appeared to be associated with social and economic developments and changes in demographic factors. Improvements in registry systems and diagnostic capacities were also probably responsible for these growing trends. Raising general awareness and improving screening programs, early detection measures, and equitable access to healthcare systems might be the initial steps to tackle the increasing trends.

Predictors of the worry about cancer recurrence among women with breast cancer

INTRODUCTION

Worry about cancer recurrence is identified as the most common psychological burdens experienced by cancer patients and survivors. The present study aimed to determine the predictors of worry about cancer recurrence among women with breast cancer.

MATERIALS AND METHODS

This cross-sectional study was conducted on 166 women with breast cancer undergoing chemotherapy and radiotherapy, who referred to private and public oncology centers in Tabriz, Iran using the convenience sampling. Data collection tools were demographic and disease characteristics questionnaire, cancer worry scale, social support questionnaire, brief illness perception questionnaire, international physical activity questionnaire-short form, and The EORTC-in-patsat32. The data were analyzed using SPSS 25 software. Pearson correlation coefficient, independent t-test, ANOVA, and multivariate linear regression were used.

RESULTS

In the present study, the mean (standard deviation) of score of worry about cancer recurrence was 17.41 (7.88), ranging from 8-32. The results revealed that the type of surgery, illness perception, satisfaction with care, and place of treatment were the most important predictors of worry about cancer recurrence, which explained 44.3% of the variance.

CONCLUSION

The enhancement of satisfaction with care and training coping strategies among individuals with high perceived severity of the illness contribute to the reduction of worry about cancer recurrence and adaptation to breast cancer.

Multicentricity in Different Molecular Subtypes of Breast Cancer: A Cross-sectional Study in Isfahan

Background

Breast cancer is the most common cancer leading to death in women. Women with multicentric breast cancer were reported more likely to have poor prognosis. Here, we decided to study and compare the frequency distribution of multicentricity in different subtypes of breast cancer.

Materials and Methods

This is a cross-sectional study that was performed in 2019-20 on medical records and breast pathology reports of 250 patients who undergone mastectomy due to breast cancer. Demographic data of all patients including age, along with other medical data such as menstruation condition, breast cancer grade, multicentricity status, stage, and expression of estrogen receptor (ER), progesterone (PR), and human epidermal growth factor receptor 2 (HER2) receptors were collected from medical records. Samples were divided into four subtypes of Luminal B, Luminal A, HER2 expressing, and basal-like.

Results

The mean age of patients was 50.21 ± 11.15 years. Ninety-five patients (38%) had multicentricity and HER2 expressing (48.5%) and Luminal A (41.4%) were most common in patients with multicentricity. In addition, basal-like group presented with least multicentricity (13.5%) among the subtypes (P = 0.008). We also showed significant increased chances of multicentricity in Luminal B (odds ratio [OR] = 3.782) (P = 0.033), Luminal A (OR = 5.164) (P = 0.002), and HER2-expressing group (OR = 5.393) (P = 0.011).

Conclusions

Taken together, we showed significantly increased chances of multicentricity in patients with HER2-expression, Luminal A, and Luminal B groups compared to basal-like group or triple negative. These results were in line with most previous studies; however, we showed higher rates of multicentricity among our population compared to some previous reports.

Design and Psychometric Evaluation of Mammography Behavior Predicting Scale (MBPS)

Background: Breast cancer disease is an important public health trouble in the world. Over the past 2 decades, incidences of breast cancer among Iranian women have shown an alarmingly rapid increase. Mammography screening can lead to early detection and management of breast cancer and it also plays an important preventive role in decreasing breast cancer, especially among women over 40 years old. Objectives: This paper aims at reporting the psychometric properties of a questionnaire on mammography behavior based on health action process approach (HAPA) model. Methods: This cross-sectional study was performed between May and September 2017, and was attended by 400 women aged 40 years and older, in comprehensive health service centers in Iran. The research subjects were selected by multi-stage cluster sampling. The instrument was designed basis on the constructs of HAPA and current literature. The scale’s psychometric properties were examined by exploratory factor analysis (EFA), infraclass correlation coefficient (ICC), and Cronbach’s alpha. Results: The results showed 45 items of the questionnaire, 41 items had important item-to-total correlations (P < 0.05), and they were placed in 8 factors that contributed 60.88% of the scale variance. Conclusions: The research findings contribute to the reliability and validity of the HAPA model for predictively evaluating mammography goals.

Effects of oral N-acetyl cysteine on pain and plasma biochemical parameters in fibrocystic breast disorder: A randomized controlled trial

Background

Fibrocystic change is the most common benign lesion in breasts of a woman in her reproductive age. It is an outcome of estrogen excess due to sex hormone imbalance. Cyclical pain as the most common symptom worsens life quality, compels patient to seek health care support continuously, and imposes large amounts of expense to both patient and health system. Current study aims to evaluate effects of N-acetyl cysteine on decreasing pain and changes in plasma biochemistry.

Method

A total of 64 eligible women participated in this double-blinded randomized controlled trial. They were between 18 and 40 years. Participants were randomly allocated into oral N-acetyl cysteine and placebo receivers. Intervention and follow-up lasted for, respectively, a 12-week drugs-on and 12-month drugs-off period. Visual analog scaling was applied to measure severity of pain. Peripheral venous plasma was extracted and compared for inflammatory parameters including high-sensitivity C-reactive protein, total antioxidant capacity, malondialdehyde, total plasma glutathione, lipid profile, and fasting blood sugar.

Results

Oral N-acetyl cysteine significantly decreased feeling of cyclical mastalgia (P < .01) after 12 weeks of consumption. In addition to lowering of plasma level of high-sensitivity C-reactive protein (P = .008), total plasma glutathione significantly increased (P = .02) among N-acetyl cysteine receivers. No change in lipid profile and insulin sensitivity was seen.

Conclusion

N-Acetyl cysteine could mitigate cyclical mastalgia. Inflammation as a considered reason for cyclical mastalgia also was halted by N-acetyl cysteine consumption.

•

Daily oral N-acetyl cysteine effectively improves breast pain in FCC.

•

NAC breaks inflammatory pathways associated with cyclical mastalgia.

•

HDL-cholesterol and total plasma glutathione could be amended following NAC consumption.

The effect of a support program on the burden of spouses caring for their partners with breast cancer: a randomized controlled trial

Objective

This study aimed to determine the effect of a support program on burden of spouses caring for their partners with breast cancer.

Methods

This randomized controlled trial was conducted among spouses of women with breast cancer undergoing chemotherapy at a referral chemotherapy center in Iran. They were assigned to intervention (n=40) and control (n=40) groups using permuted block randomization. Three small group sessions lasted 45–60 minutes, followed by three telephone-based sessions, lasting 15–20 minutes (twice a week). The intervention sessions included defining stress management strategies in different situations: strengthening creativity, optimism, and management in planning, and defining the role of the caregiver. Primary outcome was care burden, and secondary outcomes were spouses’ stress, satisfaction with intervention, and partners’ quality of life (QOL). The caregiver burden inventory, depression anxiety stress questionnaire, World Health Organization QOL brief version, and client satisfaction questionnaire were completed before and after the intervention and at a 6-week follow-up.

Results

Thirty-eight participants in each group with a mean age of 44.24±9.01 years completed the study. Repeated measures analysis of variance showed a significant difference in the care burden (P<0.05; effect size, 0.70), stress (P<0.05; effect size, 0.64), and women’s QOL (P<0.05; effect size, 0.67) before and after the intervention.

Conclusion

The results of this study can be used to develop interventions, targeting the care burden and stress of spouses of women with breast cancer undergoing chemotherapy.

The Clinicopathological Profile of Breast Cancer in Young Women from a Tertiary Care Center

Background Increasing number of young breast cancer patients are seen in India and many of these young breast cancer patients are considered to have more aggressive disease biology.

Aim The aim of this article was to study the clinicopathological profile of breast cancer patients in the young and older patients to understand the difference between these two groups.

Methods This was a retrospective study conducted on 421 breast cancer patients.

Results Total of 421 breast cancer patients were studied, out of which 158 patients were less than or equal to 40 years age group and 263 patients were in more than or equal to 50 years age group. Commonest T stage on presentation was T2, which was seen 56.32% of young breast cancer patients and in 64.64% of older patients. Higher nodal spread was seen in younger patients when compared with older patients (p-value = 0.00001). Older group patients had significant decline from anatomical to pathological prognostic stage group compared with younger group (29 vs. 13.29%; p-value = 0.00001). Grade 3 tumors were seen in 58.23% of younger patients and 22.05% of older patients (p-value = 0.00001). Triple-negative breast cancer was seen more commonly in younger group compared with older group (p-value = 0.0088).

Conclusions Significant number of breast cancer patients present in younger age group in India. Younger breast cancer patients tend to have higher grade tumors and triple-negative breast cancer is common in younger age groups. Pathological prognostic stage grouping appears clinically more relevant than anatomical stage groups.

Expansion of the quality of care index on breast cancer and its risk factors using the global burden of disease study 2019

BACKGROUND

Breast cancer (BC), as the top neoplasm in prevalence and mortality in females, imposes a heavy burden on health systems. Evaluation of quality of care and management of patients with BC and its responsible risk factors was the aim of this study.

METHODS

We retrieved epidemiologic data of BC from the Global Burden of Disease (GBD) 1990-2019 database. Epidemiology and burden of BC and its risk factors were explored besides the Quality of Care Index (QCI) introduced before, to assess the provided care for patients with BC in various scales. Provided care for BC risk factors was investigated by their impact on years of life lost and years lived with disability by a novel risk factor quality index (rQCI). We used the socio-demographic index (SDI) to compare results in different socio-economic levels.

RESULTS

In 2019, 1,977,212 (95% UI: 1,807,615-2,145,215) new cases of BC in females and 25,143 (22,231-27,786) in males was diagnosed and this major cancer caused 688,562 (635,323-739,571) deaths in females and 12,098 (10,693-13,322) deaths in males, globally. The all-age number of deaths and disability-adjusted life years attributed to BC risk factors in females had an increasing pattern, with a more prominent pattern in metabolic risks. The global estimated age-standardized QCI for BC in females in 2019 was 78.7. The estimated QCI was highest in high SDI regions (95.7). The top countries with the highest calculated QCI in 2019 were Iceland (100), Japan (99.8), and Finland (98.8), and the bottom countries were Mozambique (16.0), Somalia (8.2), and Central African Republic (5.3). The global estimated age-standardized rQCI for females was 82.2 in 2019.

CONCLUSION

In spite of the partially restrained burden of BC in recent years, the attributable burden to risk factors has increased remarkably. Countries with higher SDI provided better care regarding both the condition and its responsible risk factors.

Dietary glycaemic index and glycaemic load in relation to risk of breast cancer

OBJECTIVE

Previous studies on the association between glycaemic index (GI) and glycaemic load (GL) in relation to breast cancer risk are contradictory. The aim of this study was to examine the association between dietary GI and GL and risk of breast cancer in Iranian women.

DESIGN

Population-based case-control study. Dietary GI and GL were assessed using a validated Willett-format 106-item semi-quantitative FFQ.

SETTING

Isfahan, Iran.

PARTICIPANTS

Cases were 350 patients with newly diagnosed stage I-IV breast cancer, for whom the status of breast cancer was confirmed by physical examination and mammography. Controls were 700 age-matched apparently healthy individuals who were randomly selected from general population.

RESULTS

After controlling for potential confounders, individuals in the highest tertile of dietary GI had 47 % higher odds of breast cancer than women in the lowest tertile (OR: 1·47; (95 % CI 1·02, 2·12)). Stratified analysis by menopausal status showed such association among postmenopausal women (OR: 1·51; (95 % CI 1·02, 2·23)). We found no significant association between dietary GL and odds of breast cancer either before (OR: 1·35; (95 % CI 0·99, 1·84)) or after adjustment for potential confounders (OR: 1·24; (95 % CI 0·86, 1·79)). In addition, stratified analysis by menopausal status revealed no significant association between dietary GL and odds of breast cancer.

CONCLUSIONS

Our findings showed a significant positive association between dietary GI and odds of breast cancer. However, we observed no significant association between dietary GL and odds of breast cancer.

Acceptability and compliance with a breast cancer prevention campaign in the Northwest Region, Iran

Aim: Breast cancer screening intended to improve survival and treatment outcomes. This study aimed to document the acceptability and compliance of the breast cancer prevention campaigns. Materials & methods: Healthy women aged 35–65 years were recruited from various regions of the Northwest of Iran. All women were invited to participate in self-examination training for the breast and then re-assessed by clinical examination and mammography. Results: A total of 321 healthy women were recruited, and volunteered to undergo at least one breast self-examination. The first and second clinical examinations were conducted on all women. Ultimately, 272 women (84.7%) underwent mammography. The most common barriers to screening were found to be fear of positive results, fear of cancer, lack of knowledge, fear of the mammography procedure and pain, travel distance and costs. Conclusion: The most critical challenge for implementing a breast cancer prevention program was the lack of knowledge and attitude.

Germline Mutation Analysis in Sporadic Breast Cancer Cases With Clinical Correlations

Demographics for breast cancers vary widely among nations. The frequency of germline mutations in breast cancers, which reflects the hereditary cases, has not been investigated adequately and accurately in highly-consanguineous Pakistani population. In the present discovery case series, germ-line mutations in twenty-seven breast cancer candidate genes were investigated in eighty-four sporadic breast cancer patients along with the clinical correlations. The germ-line variants were also assessed in two healthy gender-matched controls. The clinico-pathological features were evaluated by descriptive analysis and Pearson χ² test (with significant p-value <0.05). The most frequent parameters associated with hereditary cancer cases are age and ethnicity. Therefore, the analyses were stratified on the basis of age (≤40 years vs. >40 years) and ethnicity. The breast cancer gene panel assay was carried out by BROCA, which is a genomic capture, massively parallel next generation sequencing assay on Illumina Hiseq2000 with 100bp read lengths. Copy number variations were determined by partially-mapped read algorithm. Once the mutation was identified, it was validated by Sanger sequencing. The ethnic analysis stratified on the basis of age showed that the frequency of breast cancer at young age (≤40 years) was higher in Sindhis (n = 12/19; 64%) in contrast to patients in other ethnic groups. Majority of the patients had stage III (38.1%), grade III (50%), tumor size 2–5 cm (54.8%), and invasive ductal carcinoma (81%). Overall, the analysis revealed germ-line mutations in 11.9% of the patients, which was not significantly associated with younger age or any particular ethnicity. The mutational spectrum was restricted to three genes: BRCA1, BRCA2, and TP53. The identified mutations consist of seven novel germ-line mutations, while three mutations have been reported previously. All the mutations are predicted to result in protein truncation. No mutations were identified in the remaining twenty-four candidate breast cancer genes. The present study provides the framework for the development of hereditary-based preventive and treatment strategies against breast cancers in Pakistani population.

The Association between Consumption of Dairy-Originated Digestion Resistant and Bioactive Peptides and Breast Cancer Risk: A Case-Control Study

Bioactive peptides (BPs) content of dairy products is suggested to be a significant ingredient for reducing breast cancer (BC) risk. There is no observational study regarding the correlation between BPs and the risk of chronic disease because BPs' content of food items has not been evaluated in any study. The goal of the current study was to assess the association of dairy-originated BPs with BC risk. One hundred thirty-four women with BC and 267 cancer-free controls were selected from referral hospitals in Tehran, Iran. The development of an in-silico model for estimation of the bioactive and digestion-resistant peptides content of dairy products was done in our previous research. The risk assessment for BPs and BC association was performed across the tertiles of the peptide's intake. Odds ratios (OR) were calculated by logistic regression. The negative association of all bioactive and digestion-resistant peptides except for peptides with high hydrophilicity and low bioactivity was seen in all models. In PR-negative subjects only the association of total dairy intake (OR: 0.61; 95% CI: 0.26-1.45; P _{for trend}: 0.276), peptides with low bioactivity (OR: 0.40; 95% CI: 0.16-1.02; P _{for trend}: 0.0.052), antidiabetic peptides (OR: 0.42; 95% CI: 0.17-1.05; P _{for trend}: 0.0.062) and di-peptides (OR: 0.42; 95% CI: 0.17-1.05; P _{for trend}: 0.0.062) were not significant in the final model. Also, no significant association between ER-negative subjects and total dairy intake (OR: 0.41; 95% CI: 0.16-1.07; P _{for trend}: 0.0.068) was noted. Our findings deduced that milk-derived BPs negatively associate with the risk of ER/PR/HER2 negative BC among Iranian women.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.2009884.

Evaluation of the indication of BRCA1/2 genetic tests in Iranian women and acceptance rate of risk-reducing surgeries in BRCA mutation carriers

BACKGROUND

A higher risk for breast and ovarian cancer has been reported in BRCA carriers and prophylactic surgeries are proposed to reduce this risk. This retrospective cohort study has evaluated the indication of BRCA1/2 genetic tests in Iranian women and the rate of women's acceptance of prophylactic surgeries recommended by the surgeon.

METHODS

Medical records of 147 high-risk women according to NCCN clinical practice guidelines who referred for BRCA mutations testing were assessed. Individual information, indications for BRCA1/2 genetic testing and their results, physician recommendations, and type of accepted surgery were registered. To evaluate the current status of women an active visit follow-up every six months was conducted.

RESULTS

The mean age of women was 43.40 ± 10.94 and the median follow-up time was 1.92 years. Genetic test results showed 49(33.3%) women were positive for either BRCA1/2 mutations. Although the occurrence of breast cancer younger than 40 was the most common indication for genetic tests (26.5%), positive breast cancer history in first-degree relatives and two relatives younger than 50 was the most common indications with positive results. The rate of acceptance of prophylactic mastectomy and bilateral salpingo-oophorectomy was (14.3% and 34.7%) in BRCA mutation carriers.

CONCLUSION

If the onset of breast cancer at a young age (less than 40) will be the only indication for a BRCA analysis, the rate of a positive result (12.8%) is very low. Further studies are warranted to evaluate the age limit for genetic testing in our country. Prophylactic mastectomy acceptance is very low in BRCA1/2 carriers in our centers.

The Efficacy of Time Perspective Therapy in Reducing Symptoms of Post-traumatic Stress, Anxiety, and Depression in Females with Breast Cancer

Background: Breast cancer is the biggest risk factor that endangers women's health. It is considered the highest stress-causing disease due to the unpleasant effects of disease on different aspects of patients’ life. Breast cancer is commonly associated with the symptoms of post-traumatic stress and its comorbidities such as anxiety and depression. It appears that time perspective therapy (TPT), as a new psychological treatment, can reduce the symptoms of post-traumatic stress, anxiety, and depression in females with breast cancer. Methods: This is a randomized controlled trial conducted from February to September 2019. A total of 30 patients with breast cancer were selected through a convenience sampling technique and were randomly divided into the control and treatment groups. The latter group attended 6-week sessions (each session lasted 90 minutes long) to receive TPT. To conduct pretest and posttest, all participants in the two groups were asked to fill out the following questionnaires: (1) Zimbardo Time Perspective Inventory (ZTPI); (2) The Post-traumatic Stress Disorder Checklist (PCL); (3) Beck Anxiety Inventory (BAI); and (4) the second version of Beck Depression Inventory (BDI-II). The analysis of covariance (ANCOVA) was used to evaluate the effects of treatment. A P-value smaller than 0.05 was considered significant. Results: Data analysis of 28 patients from the experimental and control groups showed that TPT significantly reduced the symptoms of post-traumatic stress, anxiety, and depression in the treatment group (P < 0.001 for symptoms of post-traumatic stress and anxiety, and P = 0.002 for depression). Such a difference was not seen in the control group. Conclusions: TPT may be an effective approach to reduce symptoms of post-traumatic stress, anxiety, and depression in Iranian women with breast cancer. Further investigations are required to confirm these findings, which may in turn help heath care professionals use TPT to promote the mental health of females with breast cancer.

Characteristics of breast cancer patients at dr. Sardjito Hospital for early anticipation of neutropenia: Cross-sectional study

The highest prevalence of breast cancer in Indonesia is in the Province of Yogyakarta. dr. Sardjito General Hospital has quite complete clinical data on breast cancer patients. Characteristics of the population in various regions in Indonesia are different from one another. This problem is the basis for doing this research. Statistical data analysis needs to be done in each area for better diagnosis and treatment of cancer. Data recording is carried out continuously during outpatient treatment at dr. Sardjito General Hospital. Data for breast cancer patients was taken from July 2018 to June 2020. The data obtained were grouped into four categories: laboratory investigation, socio-demographic, clinical examination, and pathology. Descriptive and correlation analysis aims to determine the characteristics of breast cancer patients seeking treatment at dr. Sardjito General Hospital and anticipate their possibility of developing neutropenia after chemotherapy. The results of the descriptive analysis are significant to determine patient characteristics and treatment steps that can be taken. Correlation analysis variables closely related to neutrophils included leucocyte count, lymphocyte, monocyte, albumin, age at first diagnosis, and height. These variables can be a severe concern of medical personnel before undergoing chemotherapy, especially lymphocytes, which have the largest (negative) correlation and can be an early sign of neutropenia.

•

Characteristics of the population in various regions in Indonesia are different from one another.

•

The results of the descriptive analysis are essential to determine patient statistics and the treatment steps taken.

•

The strong correlation with neutrophils are leukocytes, lymphocytes, monocytes, albumin, age, and height.

Association of Estrogen Receptor, Progesterone Receptor, and Human Epidermal Growth Factor Receptor 2 Expression with Breast Cancer Metastasis in Iran

BACKGROUND

Metastasis is an important factor in the survival estimate of patients with breast cancer. The present study aimed to examine the frequency of epidermal growth factor receptor 2 (HER2), estrogen receptor (ER), and progesterone receptor (PR) expression in relation to the metastatic site, pattern, and tumor size in patients with metastatic breast cancer (MBC).

METHODS

In this retrospective study, the medical records of patients diagnosed with MBC at Motahari Clinic (Shiraz, Iran) during 2017-2019 were examined. Metastasis was confirmed using computed tomography, and a total of 276 patients were included in the study. Based on the expression of receptors, the patients were categorized into luminal A, luminal B, HER2, and TNBC groups. The frequency and percentage of receptors in relation to the metastatic site, size, and pattern were compared using the Chi square test. P<0.05 was considered statistically significant.

RESULTS

The frequency of receptor positivity in the 276 selected medical records were of the subtype HER2-enriched (n=48), luminal A (n=43), luminal B (n=146), and TNBC (n=39). The most common metastatic sites were the bones (47.1%), lungs (34.4%), liver (27.9%), brain (20.3%), and other organs (12.7%). The first site of metastasis occurred in the bones (36.6%), lungs (17.4%), liver (15.6%), brain (10.5%), and other organs (7.6%). The frequency of receptor expression was different in relation to the first metastatic site (P=0.024). There was a statistically significant difference between the frequency of receptor expression in patients with bone (P=0.036), brain (P=0.031), and lung (P=0.020) metastases. The frequency of receptor expression was also significantly different in relation to the size of liver metastasis (P=0.009). Luminal A and B subtypes showed higher rates of bone metastasis as the first metastatic site.

CONCLUSION

The difference in the frequency of receptor expression in relation to the metastatic site and tumor size can be used as predictive and prognostic factors in patients with breast cancer.

Adherence to Lifelines Diet Score (LLDS) Is Associated with a Reduced Risk of Breast Cancer (BrCa): A Case-Control Study

BACKGROUND

Previous evidence suggests a link between diet quality and breast cancer (BrCa); however, the link between the Lifelines Diet Score (LLDS)-a fully food-based score that uses the 2015 Dutch Dietary Guidelines-and risk of BrCa has not yet been evaluated. Therefore, the aim of this study was to observe the relationship between adherence to an LLDS and risk of BrCa in Iranian adults.

METHODS

In the hospital-based case-control study, 253 patients with BrCa and 267 non-BrCa controls were enrolled. Individual's food consumption was recorded to calculate LLDS using a semiquantitative food frequency questionnaire. In adjusted models, the association between the inflammatory potential of the diet and the risk of BrCa was estimated by using binary logistic regression.

RESULTS

Compared with control individuals, BrCa patients significantly had higher waist circumference (WC), first pregnancy age, abortion history, and number of children. In addition, the mean intake of vitamin D supplements and anti-inflammatory drugs in the case group was significantly lower than the control group. Furthermore, after adjusted potential confounders, individuals in the highest vs. lowest quartiles of LLDS showed statistically significant lower risk of BrCa in overall population (OR: 0.21; 95% CI: 0.11-0.43; P trend <0.001), premenopausal (OR: 0.26; 95% CI: 0.10-0.68; P trend = 0.003), and post-menopausal women (OR: 0.20; 95% CI: 0.06-0.60; P trend = 0.015).

CONCLUSION

Findings of this study reflected that higher LLDS decreased risk of BrCa, but need further investigation in later studies.

The perceived social support by Iranian women with breast cancer: a qualitative study

BACKGROUND

Social support has an important role in improving health outcomes and is considered as one of the crucial aspects of the modern care in cancer patients. Therefore, this article aims to explain the perceived experiences of women suffering from breast cancer towards social support.

METHODS

In this qualitative study, 22 women with breast cancer were selected through purposive sampling from 5 hospitals affiliated to Urmia University of Medical Sciences. The data were collected through semi-structured interviews and were analyzed by the Conventional Qualitative Content Analysis and Graneheim's and Lundman's approach, using MAXQDA software, version 10.

RESULTS

After completion of the analyzing process, 6 categories were appeared including "creating an empathic atmosphere by family and community," "being in relationship with others," "adaption to disease," "giving meaning to life," "satisfaction with the role of healthcare providers," and "the impact of others support in fighting with the disease."

CONCLUSION

According to the findings, good social support during the illness can result in the spiritual, mental, and physical well-being of the patients and is one of the most effective factors in fighting the disease and feeling of recovery. The findings of this study can be used to develop plans to help the patients to achieve more support from the family, healthcare providers, and the community and even providing the required supportive care for this group of women.

Food Quality Score and Risk of Breast Cancer among Iranian Women: Findings from a Case Control Study

The quality of foods we consume may be an important risk factor for breast cancer (BrCa); however, relations between quality of food metrics and BrCa risk have not been systematically investigated. The purpose of this study was to examine the association between food quality score (FQS) by assessing the intake of healthy and unhealthy food and the odds of (BrCa) among Iranian women. This hospital-based case-control study was carried out on 150 women with pathologically confirmed breast cancer within the past three months and 150 healthy controls that were age-match from the Cancer Research Center, Imam Khomeini hospital, Iran. Participants were interviewed to obtain data relating to diet (using a 147-item validated FFQ) and BrCa risk factors. We found a significant association between adherence to the FQS and odds of breast cancer in the fully adjusted model (OR: 0.58; P = 0.04) and in premenopausal women in the fully adjusted model (OR: 0.45; P = 0.02); however, we did not observe any association between postmenopausal women in the adjusted model (OR: 0.76; P = 0.5). We also failed to observe any association between healthy (p = 0.3) and unhealthy subgroups (p = 0.3) of FQS. Our findings suggest that adherence to FQS may be associated with an increased risk of breast cancer in crude and adjusted models in overall and premenopausal women. However, we did not see any association between FQS and BrCa risk in postmenopausal women. Prospective cohort studies are needed to confirm these findings.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.1957136 .

Dietary Carbohydrate Quality and Quantity and Risk of Breast Cancer among Iranian Women

OBJECTIVE

This study investigated the association between quality and quantity of carbohydrate by assessing low carbohydrates diet score (LCDS), carbohydrate quality score (CQI), glycemic index (GI), dietary glycemic load (GL), and dietary carbohydrate intake, and risk of breast cancer (BrCa) among Iranian women.

METHODS

This hospital-based case-control study was carried out in the Cancer Research Center of Imam Khomeini hospital, Iran. We included One hundred and fifty newly diagnosed BrCa cases and one hundred and fifty healthy controls in this study. Socio-demographic and dietary data and anthropometric measures were recorded.

RESULTS

We found that a higher CQI than a lower score was associated with a decrease in odds of BrCa (P = 0.04). After adjusting for potential confounders, we observed that CQI was not associated with BrCa development (P = 0.05). An increase in odds of BrCa among women in the highest tertiles of GL (P = 0.12), GI (P = 0.48), and dietary carbohydrate intake (P = 0.06) was seen, which was not statistically significant. There was also a non-significant lower chance of having BrCa with adherence to the LCDS (P = 0.09).

CONCLUSION

Our findings suggest that CQI was not related to BrCa risk among Iranian women. This relation deserves to be investigated in prospective studies.

Effects of Psychoeducational Interventions Using Mobile Apps and Mobile-Based Online Group Discussions on Anxiety and Self-Esteem in Women With Breast Cancer: Randomized Controlled Trial

Background

Psychoeducation has turned into an effective tool in taking care of cancer patients and improving their psychophysical symptoms and quality of life. Despite the growing use of mobile phone apps in medical settings for improving health, evidence supporting their effectiveness in the psychoeducation of patients with breast cancer is rarely available.

Objective

This study was conducted to investigate the effect of psychoeducational interventions on anxiety and self-esteem in women with breast cancer using a mobile app and an online support group.

Methods

An unblinded randomized controlled trial based on mobile phones was conducted in Shiraz, Iran. A research assistant recruited 82 women with nonmetastatic breast cancer aged 20 to 60 years were from clinics during a face-to-face visit at the point of care and randomly assigned to an intervention group (n=41) and a wait-list control group (n=41) through blocked randomization. The intervention group received psychoeducational interventions through a mobile phone app and participated in nurse-assisted online mobile support sessions for a total four weeks, whereas the control group was put on a waiting list. The State-Trait Anxiety Inventory (STAI) and the Rosenberg Self-Esteem Scale (RSES) were used to measure the levels of anxiety and self-esteem as the main outcomes at baseline and one week after the intervention.

Results

A total of 82 patients with a mean age of 46.45 (SD 9.29) years recruited in Winter 2016 were randomly assigned to a wait-list control group (n=41) and intervention group (n=41). Five patients dropped out for different reasons. Comparing the postintervention mean scores of anxiety and its subscales using the independent t test showed statistically significant differences between the mobile psychoeducation group and controls (P<.001). The paired t test used to compare the postintervention mean scores of anxiety with its preintervention scores in the intervention group showed significant reductions in the scores of anxiety (95% CI –17.44 to –8.90, P<.001, d=1.02) and its two subscales (state anxiety: 95% CI –9.20 to –4.21, P<.001, d=0.88 and trait anxiety: 95% CI –8.50 to –4.12, P<.001, d=0.94). Comparing the postintervention mean scores of self-esteem showed statistically insignificant differences between the control and intervention groups (16.87 vs 17.97, P=.24). In contrast with the controls, using the paired t test showed that the increase in the postintervention mean scores of self-esteem were statistically significant in the intervention group compared with the preintervention scores (mean difference 2.05, 95% CI 1.28 to 2.82, P<.001).

Conclusions

This study demonstrated the key role of mobile apps in decreasing anxiety and improving self-esteem in women with breast cancer through psychoeducational interventions. Similar studies with longer follow-ups are recommended that be conducted in this context.

A Study on Breast Reconstruction in a Developing Country: A Comprehensive Evaluation of the Techniques and Oncologic Outcomes

BACKGROUND

Breast cancer, with an incidence of 33.2 per 100,000 in Iranian population, is considered as the most common cancer in Iranian women. Nowadays, with the increasing survival rates, breast reconstruction has been integrated into surgical techniques of breast cancer treatment. The aim of this study was to evaluate the current status of breast reconstruction in Iranian population.

PATIENTS AND METHODS

This retrospective study was conducted in Imam Hospital between January 2008 and June 2018. All the patients underwent breast reconstruction surgery. The trend of reconstruction and complication rates were 2 major outcomes. Logistic regression model was used to predict complications. Student t test was used to compare means.

RESULTS

Fifty-five patients underwent 60 autologous breast reconstruction surgeries and 152 patients underwent 193 prosthesis-based reconstruction surgeries. Most of cases were invasive ductal carcinoma ± ductal carcinoma in situ (126 cases, 68%). Among 253 surgeries in 207 patients, 98 cases (38.7%) were 2-stage implant, 91 (36.0%) were 1-stage implant, 3 (1.2%) were acellular dermal matrix + prosthesis, 31 (12.2%) were pedicled transverse rectus abdominis myocutaneous flap, 25 (9.8%) were latissimus dorsi flap ± prosthesis, and 4 (15.8%) were latissimus dorsi flap. Among prosthesis-based reconstructions, chemotherapy could predict the occurrence of complications (odds ratio, 2.87; 95% CI, 1.07-7.68), whereas none of these factors could predict the occurrence of complications in autologous reconstructions. The most prevalent complication was seroma formation (48.5% of all complications). Overall complication rates (including major and minor) were higher among autologous reconstructions compared with prosthesis-based reconstructions (45.8% and 21.1%, respectively, P < 0.001).

CONCLUSIONS

The trend of breast reconstruction is changing in Islamic Republic of Iran as a developing country. Implant-based reconstruction has surpassed autologous reconstructions in recent years. In terms of complications, we observed higher rates among autologous reconstructions.

National and Subnational Incidence, Mortality, and Years of Life Lost Due to Breast Cancer in Iran: Trends and Age-Period-Cohort Analysis Since 1990

Breast cancer is the most common cancer among women, causing considerable burden and mortality. Demographic and lifestyle transitions in low and low-middle income countries have given rise to its increased incidence. The successful management of cancer relies on evidence-based policies taking into account national epidemiologic settings. We aimed to report the national and subnational trends of breast cancer incidence, mortality, years of life lost (YLL) and mortality to incidence ratio (MIR) since 1990. As part of the National and Subnational Burden of Diseases project, we estimated incidence, mortality and YLL of breast cancer by sex, age, province, and year using a two-stage spatio-temporal model, based on the primary dataset of national cancer and death registry. MIR was calculated as a quality of care indicator. Age-period-cohort analysis was used to distinguish the effects of these three collinear factors. A significant threefold increase in age-specific incidence at national and subnational levels along with a twofold extension of provincial disparity was observed. Although mortality has slightly decreased since 2000, a positive mortality annual percent change was detected in patients aged 25-34 years, leading to raised YLLs. A significant declining pattern of MIR and lower provincial MIR disparity was observed. We observed a secular increase of breast cancer incidence. Further evaluation of risk factors and developing national screening policies is recommended. A descending pattern of mortality, YLL and MIR at national and subnational levels reflects improved quality of care, even though mortality among younger age groups should be specifically addressed.

Prediction of Breast Cancer Survival by Machine Learning Methods: An Application of Multiple Imputation

Background:

The low breast cancer survival rates in less developed countries are critical. The machine learning techniques predict cancers survival with high accuracy. Missing data are the most important limitation for using the highest potential of these techniques to predict cancers survival. Multiple imputation (MI) was implemented and analyzed in detail to impute the missing data of a breast cancer dataset.

Methods:

The dataset was from The Omid Treatment and Research Center Urmia, Iran between Jan 2006 and Dec 2012 and had information from 856 women. The algorithms such as C5 and repeated incremental pruning to produce error reduction were applied on the imputed versions of the original dataset and the non-imputed dataset to predict and extract clinical rules, respectively.

Results:

The findings showed the performance of C5 in all the evaluation criteria including accuracy (84.42%), sensitivity (92.21%), specificity (64%), Kappa statistic (59.06%), and the area under the receiver operator characteristic (ROC) curve (0.84), was improved after imputation.

Conclusion:

The dataset of the present study met the requirements for using the multiple imputation method. The extracted rules after the application of MI were more comprehensive and contained knowledge that is more clinical. However, the clinical value of the extracted rules after filling in the missing data did not noticeably increase.

A Randomized, Controlled, Parallel-Group, Trial on the Effects of Melatonin on Fatigue Associated with Breast Cancer and Its Adjuvant Treatments

Objective:

Fatigue associated with malignant conditions and their treatments is a disabling condition. This trial assessed the anti-fatigue effects of melatonin coadministration during adjuvant treatment of patients with the breast cancer.

Material and Methods:

Patients with breast cancer were randomly assigned to receive melatonin or placebo during adjuvant chemotherapy and radiotherapy. Thirty-seven patients were randomly enrolled in each group. The mean ages of patients in the intervention and control groups were 50.47 ± 10.79 and 46.05 ± 10.55 years, respectively (P = .223). The intervention group received oral melatonin (18 mg/day) from 1 week before until 1 month after the adjuvant radiotherapy. The level of fatigue was assessed before and after intervention using Brief Fatigue Inventory (BFI) in both groups. To analyze data, the Student’s t-test and the Chi-square test were used at a significance level of P ≤ .05.

Results:

The BFI score was similar before the intervention in both groups, however, after the intervention, it was significantly lower in the melatonin group (P < .001). Moreover, the frequency of severe fatigue in the melatonin group was significantly lower than in the placebo group after intervention (42.1% vs 83.3%, P < .001).

Conclusion:

Coadministration of melatonin during adjuvant chemotherapy and radiotherapy of women with breast cancer decreased the levels of fatigue associated with the malignant condition and its treatments.

The effect of motivational interviewing on the change of breast cancer screening behaviors among rural Iranian women

OBJECTIVE

The study aimed to determine the effect of motivational interviewing on the change of breast cancer screening behaviors among rural Iranian women.

METHODS

This Randomized controlled trial (RCT) was performed on 120 Iranian rural women selected through cluster random sampling method. Out of all 20 rural health centers of Abish Ahmad District, in the northwest of Iran, about one third (six clusters) were randomly selected; out of which three were randomly assigned to the control group and three to the intervention group. A list of women aged 40-69 years in the selective health centers was prepared and 60 participants were selected for each group through the convenience sampling method based on the inclusion and exclusion criteria. Then, six group sessions (two educational and four motivational interviewing sessions) were held for the intervention group. The data were collected using demographic and obstetric questionnaire, paper-based health records, and the stages of change checklist and analyzed in SPSS 24. The groups were compared through the chi square test, homogeneity test, and the sequential logistic regression with generalized estimating equations.

RESULTS

Two months after the intervention, a significant difference was found between the two groups in terms of the stages of change for clinical breast examination and mammography by taking into account the pre-intervention stages (p = 0.001).

CONCLUSION

MI-based counseling increased the Iranian rural women's motivation for displaying breast cancer screening behaviors.

PRACTICE IMPLICATIONS

The application of MI for enhancing cancer screening programs among Iranian women is suggested.

Radiation-induced Stromal Sarcoma of Breast: A Case Report and Literature Review

Introduction: Post-irradiation mammary stromal sarcoma (MSS) is a rare condition, and it is worth learning new knowledge from each case. Case Presentation: We present the case report of a 59-year-old female with a medical history of breast cancer, who presented with an axillary mass on the same side. The patient was further evaluated and finally diagnosed with MSS with chondroid differentiation. Thereafter, she underwent neoadjuvant chemotherapy to facilitate the surgical resection of the tumor. However, she experienced local progression and lung metastasis during chemotherapy. Conclusions: MSS with chondroid differentiation was resistant to the standard chemotherapy regimens of sarcoma. Radiotherapy is a potential choice in the case of chemoresistant MSS. Further trials may reveal this notion.

Cancer Trends in Iraq 2000-2016

OBJECTIVES

Precise and quantitative assessment of the trend of cancer burden enables policymakers and health managers to prioritize diseases and allocate resources better. This infers what caused a decrease or increase in the rate of cancer occurrence, and if it denotes timing of implementation of a control measure, it presents the impact on the disease rate. This study's objective was to evaluate trends in child and adult cancer in Iraq from 2000 onwards.

METHODS

We used the registries of the Iraqi Ministry of Health that were gathered from all governorates from 2000-2016. Data were presented as incidence rates to depict the trends of different types of cancers distributed by age, gender, and governorates.

RESULTS

Breast cancer witnessed a significant increase with predominance in females. Lung cancer rate increased significantly from 4.08 to 5.60/100 000 (p = 0.038), affecting males more than females. The brain cancer trend showed a bimodal pattern (two peaks in 2004 and 2011) with no significant trend change (p = 0.788). Both genders were similarly affected. The trend of stomach and colorectal cancer showed an accelerated increase after 2007.

CONCLUSIONS

Almost all cancers (particularly lung and gastrointestinal) showed constantly raising trends, especially after 2007. Only cervical and laryngeal cancer had a decreasing trend. Most cancers were predominant in males.

Posttraumatic growth in women with breast cancer: emotional regulation mediates satisfaction with basic needs and maladaptive schemas

BACKGROUND

Despite the negative consequences of breast cancer, many women experience positive changes after diagnosis.

OBJECTIVE

The aim of this study was to examine the mediating role of emotion regulation between post-traumatic growth (PTG), satisfaction of basic needs and maladaptive schemas.

METHOD

A total of 210 female patients diagnosed with breast cancer for at least six months were assessed using measures of the PTG Inventory, Basic Psychological Needs Satisfaction Scale, Young Schema Questionnaire-Short Form, and the Emotion Regulation Questionnaire. The collected data was analysed using structural equation modelling by SPSS and Amos 23.0.

RESULTS

Basic needs and maladaptive schema paths to emotion regulation and PTG, and emotion regulation path to PTG were significant. In addition, maladaptive schemas path to emotion regulation was insignificant.

CONCLUSION

The current results show that focusing on satisfaction of basic needs and using positive emotion regulation strategies positively affect PTG. Additionally, activating maladaptive schemas and using negative emotion regulation strategies have a negative effect on PTG.

Clinicopathological Features of Young Versus Older Patients With Breast Cancer at a Single Pakistani Institution and a Comparison With a National US Database

PURPOSE

The age at which women present with breast cancer varies widely among nations, and breast cancer may behave differently in younger women. Differences in clinicopathological characteristics based on age have not been well characterized in Pakistani patients with breast cancer.

METHODS

We conducted a retrospective review of patients with symptoms of breast cancer presenting to Aga Khan University Hospital (AKUH), a large tertiary care center in Pakistan, between 2001 and 2010; we compared young (≤ 40 years) versus older (> 40 years) patients in terms of their clinicopathological characteristics. We also compared this Pakistani cohort with the US population using data from the National Cancer Database (NCDB).

RESULTS

A total of 1,334 patients with breast cancer presented to our center over the 10-year review period. The median age at diagnosis was 50 years, compared with 60 years for patients in the NCDB. In the AKUH cohort, younger patients were significantly more likely than their older counterparts to present with metastatic disease (13.1% v 10.8%; P < .01). They also were more likely to present with higher-grade tumors (grade 3: 40.1% v 28.3%; P < .001), have triple hormone receptor–negative phenotype (25.4% v 14.1%, P < .001), and have positive axillary lymph node involvement (70.9% v 57.5%; P < .001) compared with older women. Younger and older patients in the AKUH cohort tended to present with higher-stage disease (P < .001) and were more likely to have triple hormone receptor–negative disease (P < .001), compared with all patients in the NCDB and with those of Indo-Pakistani origin.

CONCLUSION

Young Pakistani women, similar to their Western counterparts, present with more advanced disease and more aggressive tumor biology than their older counterparts.

Symptom Disclosure Process Among Iranian Women With Self-discovered Breast Cancer

BACKGROUND

Breast cancer is the most common malignancy among Iranian women. Symptom disclosure plays an important role in help-seeking behavior among women with self-discovered breast cancer.

OBJECTIVE

The aim of this study was to explain how symptoms are disclosed by Iranian women.

METHODS

This study was conducted based on the grounded theory qualitative approach. Twenty-two Iranian women with breast cancer, who discovered the symptoms themselves and were referred to 2 teaching hospitals in Tehran and Qazvin, were included via purposive and theoretical sampling. The data were collected through semistructured interviews and were analyzed based on the Corbin and Strauss approach.

RESULTS

The process of symptom disclosure had 5 stages including identifying the symptoms, evaluating and interpreting the symptoms, weighing the disclosure conditions, selecting the disclosure audience, and disclosing. The perceived threat was identified as the core category. On the basis of the level of threat perception and the seriousness of the symptoms, the 3 patterns of immediate disclosure, delayed disclosure, and nondisclosure were recognized.

CONCLUSION

Perceived threat is the main motivator for rapid disclosure in Iranian women with potential breast cancer symptoms and leads to a better follow-up of the symptoms. Therefore, increasing women's awareness about breast cancer symptoms, treatments, and non-follow-up consequences leads to a better perception of the threat level.

IMPLICATIONS FOR PRACTICE

According to these findings, it is very important to increase Iranian women's awareness about the symptoms of breast cancer (especially the nonspecific ones). For this purpose, it is necessary to design educational interventions.

Oncoplastic Repair in Breast Conservation: Comprehensive Evaluation of Techniques and Oncologic Outcomes of 937 Patients

BACKGROUND

Breast-conserving surgery, especially with oncoplastic breast surgery (OBS), is becoming the standard of care in the surgical management of breast cancer. We investigated the applied technique of OBS and oncologic outcomes in a large series of patients.

PATIENTS AND METHODS

This study was conducted between January 2008 and June 2018 in two centers in Iran. Patients underwent OBS. Early and late postoperative complications, oncologic outcomes, and follow-up data were documented.

RESULTS

Nine hundred thirty-seven patients with a mean ± standard deviation age of 48.1 ± 11.3 underwent OBS. Most of the patients were diagnosed with early-stage disease, of which the most common pathology was invasive ductal carcinoma (83.3%). Lateral oncoplasty was the most commonly used OBS technique (324 cases, 34.6%). The most common complication was seroma formation. Reduction-type OBS technique had the highest rate of complications (13.1%). Thirty-four patients (5.4%) experienced local recurrence, with a median recurrence time of 26.4 months. Nine patients (1.3%) died from cancer recurrence.

CONCLUSION

OBS is a safe procedure with minor complications and good oncologic outcomes. These techniques can be applied to most patients who are candidates for breast-conserving surgery.

Legume and Nuts Consumption in Relation to Odds of Breast Cancer: A Case-Control Study

Previous studies on the association between legume and nuts intake and risk of breast cancer have mainly been focused on individual components of legume or nuts, rather than consumption of the whole food group. This study aimed to investigate the relation between legume and nuts intake in relation to breast cancer in Iranian women. In this population-based case-control study, we enrolled 350 pathologically confirmed new cases of breast cancer and 700 controls which were matched with cases in terms of age and socioeconomic status. Dietary intakes were assessed using a validated block-format 168-item semi-quantitative food frequency questionnaire. Legume intake was computed by summing up the consumption of lentils, peas, chickpeas, and different kinds of beans, including red beans and pinto beans. To calculate nuts consumption, we summed up intake of mixed nuts, almond, peanut, walnut and hazelnut. Data on potential confounding variables were also collected using pre-tested questionnaires. Mean consumption of legume and nuts among cases and controls were 14.7 ± 15.0 and 2.3 ± 5.6, respectively. A significant inverse association was found between legume intake and breast cancer (OR: 0.41, 95% CI: 0.30-0.57); such that after adjusting for confounders, participants in the top tertile of legume intake had 46% lower odds of breast cancer compared with those in the bottom tertile (OR: 0.54, 95% CI: 0.36-0.88). Such inverse association was seen among postmenopausal women (OR: 0.51, 95% CI: 0.31-0.85) and also among normal-weight participants (OR: 0.49, 95% CI: 0.29-0.82). In terms of nuts intake, it was inversely associated with odds of breast cancer (OR: 0.16, 95% CI: 0.11-0.23). This association remained significant even after taking potential confounders into account (OR: 0.15, 95% CI: 0.09-0.26). The same association was also seen in premenopausal women (OR: 0.21, 95% CI: 0.14-0.31), postmenopausal women (OR: 0.23, 95% CI: 0.13-0.42), normal-weight (OR: 0.15, 95% CI: 0.08-0.28), and overweight or obese people (OR: 0.27, 95% CI: 0.10-0.71). Our findings on the inverse association of legume and nuts intake with odds of breast cancer support the current recommendations on these foods. Prospective studies are needed to further examine this link.

Tissue engineering applications in breast cancer

In Iran, breast cancer (BC) is the most prevalent cancer among women. The standard treatment for this cancer is partial or total removal of breast tissue, followed by chemotherapy and radiation. Tissue engineering (TE) has made new treatments for tissue loss in these patients by creating functional substitutes in the laboratory. In addition, cancer biology combined with TE provides a new strategy for evaluation of anti-BC therapy. Several innovations in TE have led to the design of scaffold or matrix based culture systems that more closely mimic the native extracellular matrix (ECM). Currently, engineered three-dimensional (3D) cultures are being developed for modelling of the tumour microenvironment. These 3D cultures fulfil the need for in vitro approaches that allow an accurate study of the molecular mechanisms and a better analysis of the drugs effect. In the present study, we review recent developments in utilising of TE in BC. Moreover, this review describes achievements of Iranian researchers in the field of breast TE.

Breast Cancer Survival and Incidence: 10 Years Cancer Registry Data in the Northwest, Iran

Methods

Data were obtained from East Azerbaijan cancer registry database for the 10-year period between 2007 and 2016. Survival analysis was performed to calculate the breast cancer-specific survival proportions and mortality rates. Joinpoint trend analysis was performed to estimate the incidence trend of the cancer.

Results

A total number of 4989 patients were recorded with primary diagnosis of breast cancer. Of them, we collected follow-up data for 1335 (1309 female and 26 male). The 10-year crude mortality rate was 3.34 (per 100,000). The one-, two-, three-, five-, and ten-year breast cancer-specific survival proportions were 0.92 (95% CI 0.91-0.93), 0.88 (95% CI 0.86-0.90), 0.84 (95% CI 0.83-0.86), 0.77 (95% CI 0.74-0.80), and 0.65 (95% CI 0.60-0.70), respectively. Over the study period, the age-standardized incidence rates increased from 21.68 to 36.99 (per 100,000) with an annual percentage change of 5.5 percent. Older individuals and males patients had significantly worse survival, and patients with high-grade tumors had significantly higher risk of mortality.

Conclusion

A relatively better survival for breast cancer in East Azerbaijan, Iran, was observed compared to the overall breast cancer-specific survival proportions and mortality rates in the country. However, it is still poor compared to the developed countries indicating that inappropriate treatment modalities might have played a role on this.

Common data elements of breast cancer for research databases: A systematic review

Background:

Common Data Elements (CDEs) are data-metadata descriptors used to collect research study data. CDEs facilitate the collection, processing, and sharing of breast cancer data. This study intended to explore the CDEs of breast cancer for research databases and primary care systems.

Methods:

This study was conducted using systematic search and review. This systematic literature review covered PubMed, Scopus, Science Direct, SID, ISC, Web of Science, and Google Scholar search engine. It included studies in English language with accessible full-text from the beginning of 2007 to September 2019.

Results:

Reviewing 25 studies revealed that 52 percent of studies were carried out in the US and most studies were conducted between 2013 and 2015. The most domains for using CDEs were: Pathology Report and Registry. The CDEs of breast cancer for research databases were categorized into three categories namely clinical, research, and non-clinical and indicate the importance of these data elements. Most of the studies focused on creating and deploying clinical CDEs as physical examination, clinical history and pathology data.

Conclusion:

The integration of biomedical and clinical data relevant to breast cancer enhances the power of research variable analysis and statistical analysis, thereby facilitating improved knowledge of effective therapeutic interventions. Also CDEs used to collect, store, and retrieve patient data in various health setting such as primary care and research databases.

Incidence trend of breast Cancer in women of eastern Mediterranean region countries from 1998 to 2019: A systematic review and meta-analysis

BACKGROUND

This study was conducted to provide evidence on the current status of breast cancer and its incidence trend in Eastern Mediterranean Region during 1998-2019. Also, this study aimed to investigate the association between the incidence of breast cancer and Human Development Index and some factors related to this index, including total fertility rate, and obesity, using a meta-analysis.

METHOD

Data on incidence of breast cancer were collected from various sources, including PubMed, Embase, Web of Science, and WHO, from 1998 to 2019 using systematic review and meta-analysis. Pooled age standardized rate was calculated based on study duration and quality of data using a subgroup analysis and random effect meta-analysis.

RESULTS

A total of 80 studies (545 data points) were analyzed. Pooled age standardized rate of breast cancer for Eastern Mediterranean Region was 37.1 per 100,000 person-year (95% confidence interval [CI], 34.5, 39.8) during 2011-2019. age standardized rate of breast cancer had an upward trend in Eastern Mediterranean Region from 2005 to 2019. However, the increasing trend was found to be slightly different in various regions based on quality of data. Moreover, pooled age standardized rate had a significant association with Human Development Index [- 89.2 (95% CI, - 119.8, - 58.7)] and obesity [1.2 (95% CI, 0.9, 1.5)].

CONCLUSION

Pooled age standardized rate of breast cancer in Eastern Mediterranean Region was lower than the global average. Also, the age standardized rate value and its incremental trend have been higher in countries with high-quality data than in other countries of this region in recent years. Data quality or physiological factors, such as increase in obesity rates, could be the reasons for this incremental trend.

New Educational Model to Promote Breast Cancer-Preventive Behaviors (ASSISTS): Development and First Evaluation

BACKGROUND

The prevalence of breast cancer in Iran has increased. An effective approach to decrease the burden of breast cancer is prevention.

OBJECTIVE

The aim of this study was to develop and evaluate an educational model, called the ASSISTS, for promoting breast cancer-preventive behaviors in women.

METHODS

A multiphase method was used to develop the model designed to promote breast cancer prevention behaviors. A conceptual model was generated based on a secondary analysis of qualitative data. Then, a structural equation model technique was used to test the relationships among the model constructs.

RESULTS

The analysis revealed that 7 constructs could be extracted, namely, perceived social support, attitude, motivation, self-efficacy, information seeking, stress management, and self-care. Based on these constructs, a conceptual model was built and tested using structural equation modeling. The model fit was good, and the model confirmed significant relationships among the 7 constructs of breast cancer prevention.

CONCLUSION

Findings revealed that self-care behavior and stress management are influenced directly by attitude, motivation, self-efficacy, information seeking, and social support. In addition, women seek more information when they are motivated, have more self-efficacy, have a more positive attitude toward breast cancer prevention, and experience more social support.

IMPLICATION FOR PRACTICE

Cancer nurses can be at the forefront of breast cancer prevention. Because they can play a pivotal role in providing information, they can reduce women's stress and increase their self-care behavior. In addition, their social support can positively influence Iranian women's attitude, motivation, and self-care behavior. Furthermore, implementing educational programs based on this model might encourage women to practice preventive behaviors.
