Progressive relaxation training in patients with breast cancer receiving aromatase inhibitor therapy-randomized controlled trial

BACKGROUND

Aromatase inhibitors have positive impacts on the disease-free life of patients with breast cancer. However, their side effects, especially arthralgia, may be experienced by many patients. This study sought to assess the efficacy of Progressive Relaxation Exercises on the prevalent side effects of Aromatase Inhibitors in patients with breast cancer.

MATERIALS AND METHODS

This clinical trial was conducted with single-blind randomization at a physiotherapy department in a local hospital. Patients who received Aromatase Inhibitor were assigned at random to either the study or control group. The study group (n = 22) performed a Progressive Relaxation Exercises program four days a week for six weeks, while the control group (n = 22) received advice on relaxation for daily life. Data was collected before the intervention and after six weeks. The study's primary endpoint was the Brief Pain Inventory, which was used to measure pain severity. Secondary endpoints included assessments of quality of life and emotional status, which were measured using the Functional Assessment of Chronic Illness Therapy and Hospital Anxiety and Depression scales, respectively.

RESULTS

The study group exhibited a significant reduction in Pain Severity (p = 0.001) and Pain Interference (p = 0.012) sub-scores. Reduction in Pain Severity (p<0.001) and Patient Pain Experience (p = 0.003) sub-scores was also noted between the groups. Quality of Life and Emotional Status showed no significant variation both within and between the groups (p>0.05).

CONCLUSION

The study demonstrated that Progressive Relaxation Exercises caused a significant reduction in pain scores among Breast Cancer patients receiving Aromatase Inhibitors. While a decrease in pain during the 6-week period is valuable data, it is necessary to monitor the long-term effects of relaxation techniques.

The Relationship of Pathological Response and Visceral Muscle and Fat Volume in Women With Breast Cancer Who Received Neoadjuvant Chemotherapy

Objective

Differences in individual muscle/fat volumes may change the effectiveness of chemotherapy. In this study, the relationship between trunkal muscle and fat volume and body mass index (BMI) obtained before receiving neoadjuvant chemotherapy (NCT) in patients with breast cancer and complete pathological response (pCR) was investigated.

Materials and Methods

The volumes of psoas, abdominal and paraspinal muscles, and trunkal subcutaneous and visceral fat were calculated using CoreSlicer AI 2.0 opensource program from the F-18 fluorodeoxyglucose positron emission tomography/computed tomography (CT) and CT images before NCT and postoperative pCR rates to NCT were recorded. Muscle/fat volumes and BMI prior to NCT were compared in terms of pathological pCR rates. Patients were followed up regularly for recurrence and survival.

Results

Ninety-three patients were included with median (range) values for age, BMI, and body weights of 48 (28-72) years, 27 (16.8-51.6) kg/m2, and 71.94 (43-137) kg, respectively. The median follow-up time was 18.6 (6.7-59.6) months. No significant correlation was found between total muscle or fat volumes of patients with and without pCR. BMI [26.2 (16.8-51.6) kg/m2 vs. 24.6 (20.3-34.3) kg/m2, p = 0.03] and pCR rates in patients with low right-psoas muscle volume [11.74 (7.03-18.51) vs. 10.2 (6.71-13.36), p = 0.025] were significantly greater. A significant relationship was found between right psoas muscle volume and disease-free survival (DFS) (11.74 cm3 (7.03-18.51) vs. 10.2 cm3 (6.71-13.36), p = 0.025). However, no significant relationship was detected between total muscle-fat volume, BMI and overall survival and DFS (p>0.05).

Conclusion

This is the first published study investigating the relationship between the pCR ratio and body muscle and fat volume measured by CoreSlicer AI 2.0 in patients with breast cancer who received NCT. No correlation was found between the pCR ratio and total muscle plus fat volume. However, these results need to be validated with larger patient series.

Outcomes of reconstructive techniques in breast cancer using BCCT. core software

BACKGROUND

Surgery remains a priority for breast cancer treatment. This study aimed to compare the cosmetic outcomes of oncoplastic patients who had undergone breast-conserving surgery, mini-LDF (latissimus dorsi flap), and immediate implant reconstruction using both the Japanese scale and the BCCT.core (The Breast Cancer Conservative Treatment cosmetic results software) program and to validate this program.

PATIENTS AND METHODS

Patients who underwent surgery for breast cancer between 1997 and 2021 were retrospectively studied. Patients were divided into three groups: 1-those who had undergone breast-conserving surgery (245 patients, 71.3%), 2-those who had undergone mini-LDF after lumpectomy (38 patients, 11.02%), and 3- those who underwent reconstruction with implants after nipple-sparing mastectomy (61 patients, 17.68%). The patients were called for a follow-up examination, and their photos were taken. The photographs were shown to an independent breast surgeon and a plastic surgeon who was not included in the surgeries, and they were asked to evaluate and rate them according to the Japanese cosmetic evaluation scale. The same images were transferred to the computer and scored using BCCT.core.

RESULTS

The plastic and breast surgeon evaluation results showed no significant difference between the three cosmetic techniques (p = 0.99, 0.98). The results of BCCT.core software measurements were similar to the results of plastic and breast surgeons (p: 0.43).

CONCLUSION

Patients are more knowledgeable about cosmetic outcomes and expect more objective data. In this study, we used 3 different cosmetic evaluation scales. We found that these techniques give results that are compatible with each other in terms of evaluating the work done in a more concrete way. For this reason, we recommend the use of such software, which offers objective results in a subjective field such as aesthetics and is very easy to apply.

Evaluation of Anti-Mullerian Hormone Levels, Antral Follicle Counts, and Mean Ovarian Volumes in Chemotherapy-Induced Amenorrhea among Breast Cancer Patients: A Prospective Clinical Study

Estradiol (E2), a follicle-stimulating hormone (FSH), AMH, and inhibin B levels, along with AFC and MOV, are used to determine ovarian reserve in pre-menopausal women. Studies have shown that AMH levels are more sensitive than those of E2, FSH, and inhibin B and that AFC and MOV can be used to evaluate ovarian reserve. AMH, AFC, and MOV measurements were performed before and after adjuvant SC in 3-month periods for one year. Patients were classified as experiencing chemotherapy-induced amenorrhea (CIA) if they did not have menstrual cycles for a period of six months or longer following the conclusion of their chemotherapy treatment. We aimed to evaluate the factors affecting chemotherapy-induced amenorrhea in breast cancer patients treated with adjuvant chemotherapy and the performance of baseline measurements of AMH, AFC, and MOV to predict chemotherapy-induced amenorrhea. The effects of different chemotherapy regimens on the AMH level, AFC, and MOV in CIA patients were investigated. Seventy-one patients were eligible for this study, and the median age was 38 years (range: 23-45). The median follow-up was 37 months (range: 20-51), and CIA developed in 62% of the patients. The AMH level and AFC were significantly decreased one year after SC (p < 0.0001), whereas MOV was not (p = 0.507). AMH levels before chemotherapy (median: 1.520 vs. 0.755, p = 0.001) and at the end of the first year (median: 0.073 vs. 0.010, p = 0.030) and pre-treatment AFC (median: 12 vs. 4.50, p = 0.026) were lower in patients with CIA compared to those without CIA. The AMH levels before SC were the most valuable and earliest factor for predicting CIA development. In addition, there was no difference between the chemotherapy regimens (including or not including taxane) in terms of CIA development.

Efficacy of Capecitabine and Temozolomide Regimen in Neuroendocrine Tumors: Data From the Turkish Oncology Group

INTRODUCTION

This study aims to report the efficacy and safety of capecitabine plus temozolomide (CAPTEM) across different lines of treatment in patients with metastatic neuroendocrine tumors (NETs).

METHODS

We conducted a multicenter retrospective study analyzing the data of 308 patients with metastatic NETs treated with CAPTEM between 2010 and 2022 in 34 different hospitals across various regions of Turkey.

RESULTS

The median follow-up time was 41.0 months (range: 1.7-212.1), and the median age was 53 years (range: 22-79). Our results across the entire patient cohort showed a median progression-free survival (PFS) of 10.6 months and a median overall survival (OS) of 60.4 months. First-line CAPTEM treatment appeared more effective, with a median PFS of 16.1 months and a median OS of 105.8 months (median PFS 16.1, 7.9, and 9.6 months in first-, second- and ≥third-line respectively, P = .01; with median OS values of 105.8, 47.2, and 24.1 months, respectively, P = .003) In terms of ORR, the first-line treatment again performed better, resulting in an ORR of 54.7% compared to 33.3% and 30.0% in the second and third or higher lines, respectively (P < .001). Grade 3-4 side effects occurred only in 22.5% of the patients, leading to a discontinuation rate of 9.5%. Despite the differences in outcomes based on treatment line, we did not observe a significant difference in terms of side effects between the first and subsequent lines of treatment.

CONCLUSIONS AND RELEVANCE

The substantial superior outcomes in patients receiving first-line CAPTEM treatment highlight its potential as an effective treatment strategy for patients with metastatic NET.

Assessment High-Risk Breast Cancer in Older Patients: A Comparative Analysis of PREDICT Scores and TAILORx Risk Categorization

Objective

This study aimed to evaluate the relationship between PREDICT tool overall survival (OS) scores and high-risk patients according to TAILORx risk categorization in elderly hormone reseptor (HR) positive human epidermal growth factor negative early breast-cancer patients.

Materials and Methods

We conducted a retrospective study, extracting data from medical records of 64 patients diagnosed with breast cancer. A retrospective analysis was performed on all patients who had Oncotype Dx Recurrence Scores across five medical centers between 2017 and 2022. PREDICT scores were defined as calculated 10-year OS rates via PREDICT tool.

Results

The median age of the patients was 67, with a range between 65-75 years. Low-risk patients had a slightly higher two PREDICT scores compared to high-risk patients (78% vs. 73%), (81% vs. 77%), which were statistically significant. The progesterone receptor (PR) level was significantly lower in the high-risk group (3.5% vs. 80%). A unit decrease in the PREDICT scores was associated with a 11% increase in the odds of being in the high-risk group. However, these effects weren't statistically significant in the multivariate analysis. A unit decrease in the PR level was significantly associated with increased odds (by 5% in the multivariate analysis) of being in the high-risk group.

Conclusion

Our study underscores the importance of using a combination of tools, including the PREDICT tool, PR levels, and TAILORx risk categorization, for a comprehensive risk assessment in these patients, especially in the older population. Accurate risk assessment is crucial for tailoring the treatment and optimizing outcomes in this vulnerable population. Future studies are warranted to further validate these findings in larger cohorts and to explore additional biomarkers and genomic signatures that may aid in the risk assessment and management of breast cancer in older patients.

MCM-2 Levels as a Potential Biomarker for Predicting High-Risk Breast Cancer Patients According to TAILORx Classification

Background

The minichromosome maintenance protein-2 (MCM-2) is a more sensitive proliferation marker than Ki-67. This study aimed to evaluate the relationship between MCM-2 and Oncotype DX recurrence score (ODX-RS) and determine an MCM-2 cutoff value in high-risk patients according to TAILORx risk categorization.

Methods

Hormone receptor (HR) positive HER-2 negative early-stage breast cancer patients (pT1-2, pN0-N1, M0) who had ODX-RS were included in the study. According to the TAILORx trial, patients were divided into two groups with high (ODX-RS ≥26) and low risk (ODX-RS <26) in terms of ODX-RS. Formalin-fixed-paraffin-embedded tissues of patients were re-evaluated, and 3 µm sections were prepared for MCM-2 immuno-histochemical staining. The relationship between ODX-RS and the percentage of MCM-2 staining was evaluated in two groups. The ROC curve analysis was performed to determine the MCM-2 cut-off value for the TAILORx high-risk group (ODX-RS ≥26).

Results

The mean MCM-2 value was significantly higher in the high-risk group [(60.2 ± 11.2 vs 34.4 ± 13.8, p < 0.001)]. In the multivariate analysis, MCM-2 (OR: 1.27, 95% CI: 1.08-1.49, p = 0.003) and progesterone receptor (PR) levels ≤10% (OR: 60.9, 95% CI: 4.1-89.7, p = 0.003) were found to be independent factors indicating a high-risk group. A one-unit increase in MCM-2 level increased the likelihood of being in the high-risk group by 1.27 times. In the ROC curve analysis, the optimal MCM-2 cut-off level was 50 (AUC: 0.921, sensitivity: 86.7%, specificity: 96.0%, p < 0.001).

Conclusion

Our study is the first study in the literature to investigate the relationship between ODX-RS and MCM-2 levels in HR-positive HER-2 negative early breast-cancer patients. In this study, MCM-2 was an independent risk factor in identifying high-risk patients according to TAILORx risk classification. MCM 2 cut-off value (50) may help the decision on adjuvant chemotherapy in patients where the Oncotype DX test cannot be performed.

Clinical and inflammation marker features of cancer patients with COVID-19: data of Istanbul, Turkey multicenter cancer patients (2020-2022)

OBJECTIVE

We aimed to identify a rapid, accurate, and accessible biomarker in the early stages of COVID-19 that can determine the prognosis of the disease in cancer patients.

METHODS

A total number of 241 patients with solid cancers who had a COVID-19 diagnosis between March 2020 and February 2022 were included in the study. Factors and ten different markers of inflammation were analyzed by year of diagnosis of COVID-19 and grouped by severity of infection.

RESULTS

Hospitalization, referral to the intensive care unit (ICU), mechanical ventilation, and death were more frequent in 2020 than in 2021 and 2022 (mortality rates, respectively, were 18.8%, 3.8%, and 2.5%). Bilateral lung involvement and chronic lung disease were independent risk factors for severe disease in 2020. In 2021-2022, only bilateral lung involvement was found as an independent risk factor for severe disease. The neutrophil-to-lymphocyte platelet ratio (NLPR) with the highest area under the curve (AUC) value in 2020 had a sensitivity of 71.4% and specificity of 73.3% in detecting severe disease (cut-off > 0.0241, Area Under the Curve (AUC) = 0.842, p <.001). In 2021-2022, the sensitivity of the C-reactive protein-to-lymphocyte ratio (CRP/L) with the highest AUC value was 70.0%, and the specificity was 73.3% (cut-off > 36.7, AUC = 0.829, p = .001).

CONCLUSIONS

This is the first study to investigate the distribution and characteristics of cancer patients, with a focus on the years of their COVID-19 diagnosis. Based on the data from our study, bilateral lung involvement is an independent factor for severe disease, and the CRP/L inflammation index appears to be the most reliable prognostic marker.

Survival results according to Oncotype Dx recurrence score in patients with hormone receptor positive HER-2 negative early-stage breast cancer: first multicenter Oncotype Dx recurrence score survival data of Turkey

Background

The Oncotype Dx recurrence score (ODx-RS) guides the adjuvant chemotherapy decision-making process for patients with early-stage hormone receptor-positive, HER-2 receptor-negative breast cancer. This study aimed to evaluate survival and its correlation with ODx-RS in pT1-2, N0-N1mic patients treated with adjuvant therapy based on tumor board decisions.

Patients and methods

Estrogen-positive HER-2 negative early-stage breast cancer patients (pT1-2 N0, N1mic) with known ODx-RS, operated on between 2010 and 2014, were included in this study. The primary aim was to evaluate 5-year disease-free survival (DFS) rates according to ODX-RS.

Results

A total of 203 eligible patients were included in the study, with a median age of 48 (range 26-75) and median follow-up of 84 (range 23-138) months. ROC curve analysis for all patients revealed a recurrence cut-off age of 45 years, prompting evaluation by grouping patients as ≤45 years vs. >45 years. No significant difference in five-year DFS rates was observed between the endocrine-only (ET) and chemo-endocrine (CE) groups. However, among the ET group, DFS was higher in patients over 45 years compared to those aged ≤45 years. When stratifying by ODx-RS as 0-17 and ≥18, DFS was significantly higher in the former group within the ET group. However, such differences were not seen in the CE group. In the ET group, an ODx-RS ≥18 and menopausal status were identified as independent factors affecting survival, with only an ODx-RS ≥18 impacting DFS in patients aged ≤45 years. The ROC curve analysis for this subgroup found the ODx-RS cut-off to be 18.

Conclusion

This first multicenter Oncotype Dx survival analysis in Turkey demonstrates the importance of Oncotype Dx recurrence score and age in determining treatment strategies for early-stage breast cancer patients. As a different aproach to the literature, our findings suggest that the addition of chemotherapy to endocrine therapy in young patients (≤45 years) with Oncotype Dx recurrence scores of ≥18 improves DFS.

Pre-Treatment and Post-Treatment Anxiety, Depression, Sleep and Sexual Function Levels in Patients with Breast Cancer

Objective

In the phase of diagnosis and treatment of breast cancer cases, patients can usually experience sexual dysfunctions, sleep disorders and psychiatric disorders such as anxiety and depression. The main objective of our research is to study of the pre-treatment and post-treatment anxiety, depression, sleep and sexual function levels in the patients with breast cancer.

Materials and Methods

Fifty-six patients with breast cancer and 52 healthy women have participated in our study. In order to determine the anxiety, depression, sleep and sexual function levels, Sociodemographic and Clinical Data Form, Hospital Anxiety Depression Scale (HADS), Pittsburgh Sleep Quality Scale (PSQI) and Arizona Sexual Experiences Scale (ASEX) scores are utilized at pre-treatment and post-treatment phases for patients with breast cancer and our control group.

Results

According to scale scores applied to patients and control group, it has been determined that patients with breast cancer HADS sexual and sleep disorders, that their HADS and PSQI scores were higher and that ASEX scores decreased significantly (p<0.05). According to the scale scores calculated before and after treatment, there was a significant decrease in HADS and PSQI scores, whereas SEX scores have been increased significantly (p<0.05).

Conclusion

According to the findings of our study, anxiety, depression, sexual dysfunction and sleep disorders in patients with breast cancer are far more explicit in the pre-treatment phase than post-treatment phase. Therefore, it is crucial to psycho-socially support patients with breast cancer in the early periods before starting the treatment after diagnosis.

The Effect of Systemic Chemotherapy on Ovarian Function: A Prospective Clinical Trial

Objective

Premenopausal women with breast cancer are at risk of developing ovarian failure after chemotherapy. The aim of this study was to investigate the negative effects of systemic chemotherapy on ovarian function in premenoupausal women with breast cancer.

Materials and Methods

Thirty-one premenopausal women with operable breast cancer aged between 26-48 years were enrolled in this prospective cohort study to investigate preliminary results. Additional 69 patients' data will be included after the completion of all five measurements. The change in serum Antimullerian Hormone (AMH) levels, mean ovarian volumes (MOV) and antral follicle counts (AFCs) at 3-month intervals were recorded to evaluate ovarian function. Women who had at least one pretreatment and four post-treatment measurements in one year follow-up period were included in the study. Decision of chemotherapy regimen was taken by the Tumor Board.

Results

Thirty-one patients had all five AMH, MOV and AFCs results. There was a statistically significant negative correlation between 1^st - 5^th AMH levels (p=0.006) and 1^st - 5^th AFCs during the follow-up period (p<0.0001). However pre- and post-chemotherapy measurements of MOVs did not demonstrate any significant correlation (p=0.799). BMI, parity, lactation, histopathology and molecular subtypes of breast cancer, alcohol intake, smoking and type of chemotherapy regimen were not significantly correlated with AMH, AFC and MOV.

Conclusion

Pretreatment AMH levels and AFC were shown to have a significant role in early prediction of ovarian-reserve after chemotherapy.

The Effect of Mini-Latissimus Dorsi Flap (MLDF) Reconstruction on Shoulder Function in Breast Cancer Patients

Objective

The aim of this study is to investigate the effect of mini latissimus dorsi flap (MLDF) reconstruction on ipsilateral shoulder functions.

Materials and Methods

Those included in the study are the patients aged between 23 and 73, who were operated with the diagnosis of early breast cancer (cT1-3)N0). The first group includes the patients who had sentinel lymph node biopsy (SLNB) with partial mastectomy. The second group consists of the patients who had axillary lymph nodule dissection (ALND) with partial mastectomy. The third group includes the patients who had SLNB and MLDF with partial mastectomy. The fourth group includes the patients who had ALND and MLDF with partial mastectomy. Patients' Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) score work model point were recorded.

Results

174 patients were included in this study. According to Q-DASH score, no functional change was detected in 69.5% of the patients, whereas slight functional loss was identified in 23.6%, moderate functional loss in 5.7%, severe functional loss 1.1%. In the comparison of Q-DASH scores in surgery groups, while these four groups were being analyzed, a significant difference was determined (p=0.007). When dual analyses were made, it was also established that the difference resulted from the group to which ALND and MLDF were applied together.

Conclusion

We conclude that MLDF application for reconstruction purposes after breast surgery has a negative impact on shoulder functions of the patients who had both of partial mastectomy and ALND.

Prognostic Significance of Adjuvant Chemotherapy Induced Amenorrhea in Luminal A and B Subtypes

Objective

In this retrospective study, chemotherapy induced amenorrhea in patients with early stage breast cancer and its effects on survival were investigated.

Materials and Methods

Two hundred fifty-two patients received adjuvant chemotherapy without ovarian suppression treatment (OST) from 600 premenopausal patients were included in the study. Patients were divided into two groups; with amenorrhea and without, and compared with clinicopathologic features and survival. SPSS version 17 was used.

Results

Chemotherapy-induced amenorrhea (CIA) was observed in 145 (57.5%) of 252 patients who received no OST during follow-up. The 5-year OS rate of patients with CIA was significantly higher than patients without CIA (p= 0.042, 95.9% vs. 89.7% vs. 158.88 vs. 135.33 months, respectively). In the subgroup analysis, the OS in patients with hormone receptor (+) was significantly higher than in those receptor (-) in patients with CIA (p=0.011, 97.5% vs. 90.9% vs. 162.13 vs. 126.16 months, respectively). The OS was significantly longer in the luminal A molecular subtype than in those with luminal B molecular subtype, in patients with CIA, but the difference was not significant in patients without CIA (p=0.027 vs. p=0.074, respectively).

Conclusion

As a conclusion; survival advantage of the chemotherapy induced amenorrhea more pronounced with hormone receptor positivity, lymph node involvement, and advanced disease over patients who do not develop amenorrhea. This advantage of amenorrhea development further prolongs survival compared with luminal B in the luminal A molecular subtype.

Possible role of stress, coping strategies, and life style in the development of breast cancer

Objective The aim of the present study was to investigate the possibility of the effect of life long stressful events, along with coping method used, perception of social support, and life style on the development of breast cancer. Methods In this hospital-based case control study, the study group comprised 250 women with breast cancer who were followed by Florence Nightingale Breast Study Group. Control group included 250 women, who had similar sociodemographic characteristics to the study group. Data were collected with semi-structured interview form, Healthy Life Style Behavior Scale, Coping Strategy Indicator, and Stress Evaluation Form developed by us. Results In multivariate analysis, family history of cancer (OR: 1.55, 95% CI: 2.29-1.05), inadequate social support (OR: 1.83, 95% CI: 1.23-2.73), and loss of father during childhood (OR: 2.68, 95% CI: 5.52-1.30) and serious stressor within the last five years (OR: 4.72, 95% CI: 7.03-3.18) were found to be risk factors increasing the risk of breast cancer. When family history of cancer was excluded from the model, the presence of psychiatric disorder history (OR: 1.95, 95% CI: 3.26-1.17) and major life events (OR: 2.24, 95% CI: 4.07-1.24) were added to the model as risk factors. Conclusion The present study indicates that especially the stressful events experienced within the last five years plays an undeniable role in the risk of breast cancer. Social support may be as important in the period before the diagnosis as in the period after diagnosis.

Impact of Personality Traits, Anxiety, Depression and Hopelessness Levels on Quality of Life in the Patients with Breast Cancer

Objective

The aim of this study was to investigate the impacts of personality traits, anxiety, depression and hopelessness levels on quality of life in the patients with breast cancer.

Materials and methods

The study was performed on 90 patients diagnosed with breast cancer and 90 healthy women. Sociodemographic and Clinical Data Collection Form designed by us, Beck Hopelessness Scale (BHS), Beck Anxiety Scale (BAS), Beck Depression Scale (BDS), Eysenck Personality Inventory (EPI) and Quality of Life Scale-Short Form (SF-36) were administered to patients and to control group.

Results

The patients with breast cancer were found to indicate higher levels of anxiety and depression, lower levels of quality of life, and higher scores of personality inventory subscales as compared to the healthy control group. In the patient group, it was identified that the quality of life subscale scores were found to be negatively correlated with anxiety, depression, hopelessness and neurotic personality scores; there was a positive correlation between neurotic personality scores and depression, anxiety and hopelessness scores.

Conclusions

It can be concluded that the breast cancer patients with extraversion personality traits have lower levels of anxiety and depression, keeping their quality of life better, whereas the patients with higher neuroticism scores may have more impaired quality of life. Therefore, the psychiatric evaluation of the breast cancer patients during and after the treatment cannot be ruled out.

Roles of Biopsychosocial Factors in the Development of Breast Cancer

OBJECTIVE

The aim of this study was to determine the roles of biopsychosocial risk factors in the development of breast cancer.

MATERIALS AND METHODS

This hospital-based case-control study included 491 women with breast cancer (study group) and 512 women who did not have cancer or other serious diseases (control group). Biological, psychological, and social risk factors were compared between the two groups. Data were collected using the semi-structured interview, the Stress Assessment Form, and the Coping Strategy Indicator to assess these factors.

RESULTS

When the significantly different biopsychosocial variables between the study and the control groups were evaluated together, independent breast cancer risk factors were found as follows: a stressor experienced in the last 5 years, age 40 years and older, inadequate social support perception, use of avoidance coping strategy, being a housewife, having a family history of cancer, and having a body mass index ≥25.

CONCLUSION

This study showed a relationship between breast cancer risk and manageable variables (obesity, stressor and coping strategy, social support, and employment status), age and family history of cancer, which are biopsychosocial factors. Biopsychosocial aspects are becoming a greater part of many different healthcare systems.

The role of ultrasonographic findings to predict molecular subtype, histologic grade, and hormone receptor status of breast cancer

PURPOSE

The correlation between imaging findings and pathologic characteristics of tumors may provide information for diagnosis and treatment of cancer. The aim of this study is to determine whether ultrasound features of breast cancer are associated with molecular subtype, histologic grade, and hormone receptor status, as well as assess the predictive value of these features.

METHODS

A total of 201 consecutive invasive breast cancer patients were reviewed from the database according to the Breast Imaging and Reporting Data System (BI-RADS). Tumor margins were classified as circumscribed and noncircumscribed. Noncircumscribed group was divided into indistinct, spiculated, angular, and microlobulated. The posterior acoustic features were divided into four categories: shadowing, enhancement, no change, and mixed pattern.

RESULTS

Tumors with posterior shadowing were more likely to be of nontriple negative subtype (odds ratio [OR], 7.42; 95% CI, 2.10-24.99; P = 0.002), low histologic grade (grade 1 or 2 vs. grade 3: OR, 2.42; 95% CI, 1.34-4.35; P = 0.003) and having at least one positive receptor (OR, 3.36; 95% CI, 1.55-7.26; P = 0.002). Tumors with circumscribed margins were more often triple-negative subtype (OR, 6.72; 95% CI, 2.56-17.65; P < 0.001), high grade (grade 3 vs. grade 1 or 2: OR, 5.42; 95% CI, 2.66-11.00; P < 0.001) and hormone receptor negative (OR, 4.87; 95% CI, 2.37-9.99; P < 0.001).

CONCLUSION

Sonographic features are strongly associated with molecular subtype, histologic grade, and hormone receptor status of the tumor. These findings may separate triple-negative breast cancer from other molecular subtypes.

PET-MRI Findings of Two Patients with Breast Carcinoma before Treatment

Integrated positron-emission tomography-magnetic resonance imaging (PET-MRI) is a new hybrid simultaneous imaging modality with higher soft tissue contrast and lower radiation doses compared with PET-CT. Two patients who were referred to our hospital with left breast masses that were pathologically diagnosed as invasive ductal carcinoma. The women were then scanned using the first PET-MRI system in Turkey, which was established in our department. In this case report, we aimed to determine the advantages of PET-MRI in staging, follow-up, neoadjuvant chemotherapy response, and to compare the usefulness of this modality with PET-CT and dynamic contrast-enhanced breast MRI.

The Relationship between Bone Mineral Density and Estrogen Receptor Positivity in Patients with Breast Cancer

OBJECTIVE

The effect of estrogen on bone mineral density (BMD) and breast cancer has been known for a long time. The aim of this study was to compare of the BMD of patients with breast cancer and healthy individuals, and to investigate the degree of correlation of estrogen receptor (ER) with BMD.

MATERIALS AND METHODS

Seventy-one patients with postmenopausal breast cancer and 79 healthy dividuals were included in the study. The patient demographics (age, menopause age, body mass index, number of children, BMD, Z scores, and estrogen status for breast cancer patients) were taken from hospital records.

RESULTS

No significant difference was detected between the case and control groups in lumbar region Z scores (p=0.074). At the femur neck, the control group Z scores was higher than patient group (p=0.002). BMI was higher in the patients with breast cancer (p=0.001). There was no statistically significant correlation between ER positivity, BMD, and BMI in ER-positive patients (p=0.495, p=0.8, p=0.846, respectively). There was no difference between the Z scores when the patients were divided into two groups as ER positive and negative (p=0.156, p=0.335, respectively).

CONCLUSION

This study revealed that there is no difference in lumbar region Z scores between patients with breast cancer and heathy controls; however, the Z scores were higher in the femur neck in the control group, and the BMI was lower in the patient group. Tumor ER positivity does not positively affect BMD.
