Patients with human epidermal growth factor receptor 2 (HER2neu)-positive breast invasive cancer are known to have larger, more aggressive tumors. Little research exists on the relationship between HER2neu status and extent of ductal carcinoma in situ (DCIS). A retrospective review of a single-institution database was performed for patients with DCIS between the years 2002 and 2011. A single blinded breast radiologist reviewed preoperative imaging. Pathology was reviewed for extent of DCIS. Primary outcome was mastectomy. Multivariate logistic regression was used to determine adjusted mastectomy risk. There were 166 cases, 34 HER2neu-positive. HER2neu receptor-positive patients had larger lesions on imaging: 4.0 versus 2.7 cm, by 2.9 versus 1.5 cm ( P = 0.0499 and 0.0182). HER2neu-positive patients with DCIS were more likely than HER2neu-negative to undergo mastectomy than lumpectomy (53 vs 28%, P = 0.006). Pathology revealed a trend toward larger lesions in HER2neu-positive patients (2.96 vs 2.22 cm, nonsignificant). Patients with HER2neu-positive disease were three times more likely to undergo mastectomy (odds ratio, 2.9; 95% confidence interval, 1.23 to 6.78). Patients with HER2neu-positive DCIS had greater extent of disease by imaging and were more likely to undergo mastectomy than HER2neu-negative. These findings will help surgeons counsel patients on surgical treatment.

AbstractSalivary duct carcinoma is an aggressive malignancy with a high mortality rate, which phenotypically resembles high-grade breast ductal carcinoma. The parotid gland is the most common location. Standard treatment is surgery to the primary tumour together with post-operative radiotherapy. Despite this, there is a high rate of local recurrence, cervical nodal involvement and distant metastasis. Chemotherapy is currently considered only for end-stage, disseminated disease; however, current evidence indicates that chemotherapy used with radiotherapy may result in improved disease control and survival.Human epidermal growth factor receptor-2 is a proto-oncogene which is over-expressed in both breast ductal carcinoma and salivary duct carcinoma. Clinical studies of patients with metastatic breast cancer, using trastuzumab, a monoclonal antibody directed against human epidermal growth factor receptor-2, have shown significant efficacy in tumour response, resulting in improved survival. Such advances in immunohistochemistry, and in targeted immunotherapy for breast ductal carcinoma, should be applied to the treatment of salivary duct carcinoma.

Duodenal adenocarcinoma is a rare malignancy and carries a poor prognosis. The role of adjuvant therapy and the optimal chemotherapy regimen remain largely unclear. Treatment with trastuzumab results in prolonged survival in gastroesophageal cancer if human epidermal growth factor receptor 2 (HER2) is overexpressed or amplified in tumor cells. However, unlike gastric adenocarcinomas, duodenal cancers seem to rarely harbor HER2 amplification or overexpression. We report the case of a patient with HER2-positive stage III duodenal adenocarcinoma who has received adjuvant chemotherapy including trastuzumab.

Abstract Background: The expression of estrogen and progesterone receptors and human epidermal growth factor receptor-2 has been reported to have invaluable prognostic role. This study aimed at determining the expression ER, PR and HER2 in women with breast cancer in Kampala, Uganda.Methods: Expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2) was determined immunohistochemically. Logistic regression was performed to determine the effect of the independent factors in predicting the risk of not expressing the breast markers. A two-tailed p<0.05 was regarded to be statistically significant.Results: ER, PR and HER2 were expressed in 53.4%, 46.6% and 18.5%, respectively. Co-expression of ER and PR and triple negative breast cancer was present in 42.7% and 37.9%, respectively. Age was an independent predictor of expression of ER (AOR = 0.18, 95% CI: 0.062-0.541, p = 0.002), PR (AOR = 0.35, 95% CI: 0.129-0.968, p = 0.043).Conclusion: Majority of patients in this study had less than 50 years and the majority of them had infiltrating ductal carcinoma of no special type with grade 2. Age predicted independently the expression of both ER and PR in our study.

Introduction: Breast cancer is the most common cause of cancer death among women. Estrogen Receptor (ER), Progesterone Receptor (PR) and human epidermal growth factor receptor 2 (Her-2/ neu) status are used as an important prognostic marker for breast cancer.Objectives: The aim of this study was to evaluate ER and Her-2 in breast carcinoma among Bangladeshi women and to co-relate with other prognostic parameters.Materials and Methods: The study was carried out in a tertiary level hospital in Bangladesh during the period of January 2010 to December 2011. Total 100 histologically proved breast carcinoma cases were included in the study. Immunostaining for ER and Her-2/neu were carried out. Quick scoring of ER and expression of Her-2/neu were correlated with histomorphological parameters.Results: Among 100 cases 93 were ductal carcinoma and 07 were non ductal. Among all, 38% show ER positive (score- 3-8) while 62% are ER negative (score 0-2). Her-2/neu was over expressed in 30%, 22% were borderline and 48% were negative. There were inverse relationship between ER positivity and Her-2/neu overexpression. ER positivity was related with lower histological grade, while Her-2/neu overexpression was related with higher histological grade.Conclusions: ER positivity in Breast carcinoma patients in Bangladesh is lower in comparison to western literature while Her-2/neu overexpression rate is quite high like other Asian countries.Journal of Armed Forces Medical College Bangladesh Vol.11(1) 2015: 7-13

AbstractBackground:The incidence of human epidermal growth factor receptor 2 positivity in salivary duct carcinoma ranges from 25 to 100 per cent and is associated with a poor outcome. Salivary duct carcinoma has significant pathological similarities to ductal carcinoma of the breast.Methods and results:A 49-year-old man developed lung and liver metastasis a few months after surgery and adjuvant radiotherapy for salivary duct carcinoma of the parotid gland. There was no response to palliative chemotherapy with doxorubicin. We followed the biological model of breast cancer, whereby two-thirds of human epidermal growth factor receptor 2 positive patients respond to a combination of docetaxel and human epidermal growth factor receptor 2 blocker (trastuzumab). A durable, complete response was achieved with this combination. A rationalised treatment approach targeting the biological characteristics of salivary duct carcinoma had proven successful.
