“…Breast cancer is the second leading cause of cancer death (Ferlay et al, 2015), with 2.4 million victims worldwide from 1990 to 2015 (Fitzmaurice et al, 2017). In Iran, most patients are in the age range of 40-50-year-old (Akbari et al, 2017), which is considerably lower than that of the developed countries (Nokiani et al, 2007;Valipour et al, 2017). Besides, the social context surrounding the patients may be contaminated with some negative attitudes against their illness (Boinon et al, 2014;Badihian et al, 2017).…”

Background: Cancer stigma is rarely addressed among Iranian population and patients. The current study aimed at translating and examining the construct validity of the stigma scale for chronic illnesses 8-item (SSCI-8) among Iranian women with breast cancer. Methods: In the current study, a total of 223 patients aged 19-75 years were recruited from three cancer centers in Tehran, Iran, from 2014 to 2015. Forward-backward translation method was used. The itemtotal correlation was evaluated. Exploratory factor analysis employing maximum likelihood method and direct Oblimin rotation was conducted. Reliability was assessed using composite reliability (CR). Average variance explained (AVE) was used for convergent/divergent validity. Results: The items mean was 1.47 (0.19), the scale mean 11.75 (5.57); the inter-item correlations were positive and significant (P <0.0001). A two-factor solution with seven eligible items (five for enacted and two for internalized stigma) showed the model fitness. The CR for the total scale, as well as enacted and internalized facets was 0.78, 0.89, and 0.79, respectively; the AVE was 0.66 for each latent variable. Conclusion: The Persian version of SSCI-7 was found as a reliable and valid abbreviated instrument to assess experiences of enacted and internalized stigma among Iranian women with breast cancer.

Background:In order to evaluate the diagnostic capabilities of various methods of breast cancer, it was expected that the use of non-invasive imaging techniques would be the earliest and the best technique of patient management. Objectives: We attempted to evaluate mammography and ultrasonography reports along with clinical diagnosis and their agreement with the definite diagnosis of breast lesions by pathology report. Methods: This cross sectional study was conducted on 287 women, who were referred to the cancer research center and breast clinic in Tehran between August 2016 and September 2017. The patients' basic information and their history were asked and recorded on the checklist. Also, the information obtained from the imaging report as well as the results of the pathological assessment were extracted. Results: Compared with the pathological evaluation, the clinical assessment showed a sensitivity of 89.7%, a positive predictive value (PPV) of 97.6%, and a diagnostic accuracy of 90.24% in differentiation between malignant and non-malignant lesions. And specificity of 51.6%, and negative predictive value (NPV) of 89.2%, and a diagnostic accuracy 87.8% in differentiation between non-benign and benign lesions. Mammography had a sensitivity of 24.7%, PPV of 100%, and an accuracy of 40.2% in differentiation between malignant and non-malignant lesions. And specificity of 82.0%, NPV of 31.1%, and an accuracy of 59.0% in differentiation between non-benign and benign lesions. Ultrasonography had a sensitivity of 26%, PPV of 100%, and an accuracy of 41.44% in differentiation between malignant and non-malignant lesions. And specificity of 58.2%, NPV of 53.3%, and an accuracy of 80.6% in differentiation between non-benign and benign lesions. The cost for correct diagnosis ratio was estimated 12.31 Dollars in clinical assessment, 109.66 Dollars in mammography assessment, and 122.32 Dollars for the assessment with ultrasonography. Conclusions: We deduced that clinical assessment was in line with pathology finding in comparison to mammography and ultrasonography in differentiation between malignant and benign lesions. In conclusion, we suggest that every radiologist pass more specialized training for reporting the mammography and ultrasonography images for declining false negative and positive results.
