Background: HER-2/neu is a proto-oncogene that is amplified/overexpressed in 15 to 30% of invasive breast cancers. The purpose of this study was to determine if any relationship exist between HER-2/neu protein overexpression and estrogen receptor (ER), progesterone receptor (PR), grade, size, and lymph node status in female breast cancer. Methods: A total of 100 cases of invasive ductal breast cancer were included in this study. The hormone receptors and HER-2/neu were studied immunohistochemically (IHC). Using the HER-2/neu DAKO scoring system, scores of 0, 1+ and 2+ were defined as negative and 3+ as positive. Results: HER-2/neu protein overexpression was seen in 20 (20%) of cases. HER-2/neu protein overexpression was present in 4 of 52 T1 lesions (8%), in 11 of 37 T2 lesions (30%), in 3 of 6 T3 lesions (50%), and in 2 of 5 T4 lesions (40%), (p<0.05). Protein overexpression was seen in 7 of 17 grade III tumors (41%), and 13 of 61 grade II tumors (21%). Overexpression was not detected in grade I tumors (p<0.01). Of the 20 Her-2/neu positive cases, ER- and PR-negative status was detected in 60% and 70%, respectively. Conclusion: Statistically significant correlation was found between HER-2/neu protein overexpression and large tumor size, high histological grade, and ER-, PR-negativity. There was no correlation with lymphonodal status.

Background: Breast cancer is the most prevalent neoplasm diagnosed in Iranian women. Objectives: The current study was performed to measure the hormone receptor status and its possible connection with the patient’s age, tumor size, histological grade, and lymph node status and involvement in patients with invasive ductal breast cancer (IDBC) Methods: A total of 103 women with IDBC recently diagnosed at the Department of Pathology of Shohada-E-Tajrish Hospital were entered into this study. The mean age of the patients was 48.4 years, and 59.2% of cases were 50 years old or less. Results: Most lesions (78.6%) were more than 2 cm at their greatest dimension. Grade-II lesions were observed in a large number of patients and 59.8% of cases had lymph node involvement. Positive ER, PR, and HER-2/neu were detected in 59%, 57%, and 29% of patients, respectively. A significant correlation was found between patients’ age and histologic score, tumor dimension and both histologic score and nuclear grade, and, finally, between lymph node involvement and nuclear grade. Conclusions: According to previous studies, the evaluation of hormone receptor status in patients with breast cancer is strongly recommended. Here, by studying its possible connection with the patient’s age, tumor size, histological grade, and lymph node metastasis, we detected some biomarkers, which could be used as prognostic indices in these patients. These biomarkers could help us in the clinical management of patients with IDBC by providing the best therapeutic options.

Breast Cancer incidence is increasing, but its mortality has started to decrease. The existence of strong reliable prognostic and predictive factors is of utmost importance to the practicing clinician. Some factors are only prognostic such as age, tumor size, and lymph node status, while others are both prognostic and predictive such as hormone receptors and human epidermal receptor 2 (HER’s-2) status. This study was done to see the association of HER-2 positivity with age, tumour size, grade, differentiation and lymph node deposit in breast cancer patient. A cross-sectional type of descriptive study was conducted among 50 patients. Patient age range is from 22 to 64 years (mean 42.64 ± 10.26 years). Tumour size ranged from 1 to 8 cm (mean 4.39 ± 1.564cm). Well differentiated tumour was 20, moderately differentiated tumour was 18 cases and poorly differentiated was 12 cases. HER-2/neu negative included 35(70%) cases and positive included 15(30%) cases. In this study it was found that the association between age groups and tumour differentiation with HER-2/neu status was statistically significant (p= <0.05). TAJ 2019; 32(2): 14-21

Background: Using contrast-enhanced MR imaging in the diagnosis of breast cancer may provide additional information not only on tumor extension but also on the biological behavior of tumors. Thus certain characteristics such as tumor angiogenesis and the proliferating activity of the tumor, which have been shown to correlate significantly with prognosis, are both potentially amenable to analysis by MR imaging Material and Methods: We compared contrast enhancement in 50 malignant breast tumors at MR imaging to several prognostic factors, such as tumor size, lymph-node status, histological grade of malignancy, tumor angiogenesis, and proliferating activity as shown by the mitotic count and PCNA immunoreactivity Results: There was significant correlation between contrast enhancement at MR imaging of breast cancer and both tumor angiogenesis and proliferative cellular activity as shown by PCNA immunoreactivity. Furthermore, there was a correlation between contrast enhancement and tumor malignancy grade as well as tumor invasiveness Conclusion: These observations suggest that contrast enhancement at MR imaging may be influenced by factors that have prognostic value. If this assumption is correct, contrast-enhanced MR imaging may become a valuable prognostic tool in the pre-operative evaluation of breast cancers

Basal-like breast cancer, an aggressive subtype associated with high grade, poor prognosis, and younger age, is reported frequently in Africa. We analyzed the expression of the basal cytokeratins (CKs) 5/6 and 17 in a case series from Central Sudan and investigated correlations among basal CK status, ER, PgR, and Her-2/neu, and individual/clinicopathological data. Of 113 primary breast cancers 26 (23%), 38 (34%), and 46 (41%) were, respectively, positive for CK5/6, CK17, and combined basal CKs (CK5/6 and/or CK17). Combined basal CK+ status was associated with higher grade (P<.03) and inversely correlated with ER (P<.002), PgR (P=.004) and combined ER and/or PgR (P<.0002). Two clusters based on all tested markers were generated by hierarchical cluster analysis and k-mean clustering: I: designated ``hormone receptors positive/luminal-like’’ and II: designated ``hormone receptors negative’’, including both basal-like and Her-2/neu+ tumors. The most important factors for dataset variance were ER status, followed by PgR, CK17, and CK5/6 statuses. Overall basal CKs were expressed in a fraction of cases comparable to that reported for East and West African case series. Lack of associations with age and tumor size may represent a special feature of basal-like breast cancer in Sudan.

Two-thirds of all women who develop breast cancer each year live in Asia. In many countries, including Bangladesh, there are few data on the pathological characteristics of breast tumours. The objectives of this study were a) to describe the estrogen receptor (ER), progesterone receptor (PR), and the expression of Her-2/neu oncogene expression status in a large series of breast cancers occurring in Bangladeshi women and b) to correlate these findings with the patients' age at diagnosis, tumour histological grade, and presence of axillary lymph node metastatic disease.Method: One thousand forty two cases were evaluated in a referral practice. Tumour sections were stained immunohistochemically using Dako 1D5 (ER) and Dako 636 (PR) and semiquantitatively scored for ER and PR expression. Three hundred thirty five of these cases were also stained using Dako c-erb2 oncoprotein and scored for Her-2/neu over-expression.Results: Estrogen Receptor expression was positive in 69.0%, PR expression was positive in 72.3%, and Her-2/ neu was over-expressed (IHC score 3+) in 28.4% of the cases. Her-2/neu over-expression did not consistently correlate with ER and PR expression. ER and PR expression were inversely associated with tumour histological grade. Cases with axillary lymph node metastases had higher rates of ER and PR expression. No significant association was observed with patient’s age.Conclusion: Estrogen Receptor, PR, and Her-2/neu expression frequencies and prognostic factor associations in Bangladeshi women with breast cancer referred for tumour marker testing are very similar to those reported in Western countries. These findings have important implications for ensuring optimal testing capacity for all patients with these tumours, to allow for appropriate choices of treatment.
