Background: Overexpression of HER2-neu has been reported in many epithelial malignancies, including cancers of the breast, ovaries, lungs, prostate, bladder, pancreas, colorectum and stomach as well as osteosarcomas. The aim of this study was evaluation of expression of HER2-neu immunohistochemistry (IHC) status and clinicopathologic features in a series of colonic adenocarcinomas. Materials and Methods: In this descriptive and analytical study, we surveyed 211 samples of colon adenocarcinoma from 182 patients (86.3%) undergoing total or partial colectomy and 29 (7.13%) with biopsies by colonoscopy. A sufficient sample size was obtained from all cases and the slides were stained with hematoxylin and eosin and also by IHC (HER2) staining. Results: The mean age for the patients at diagnosis was 57.9 years (range, 15-88 years). One hundred and twenty one patients (57.3%) were male. Of all patients, 201 samples (95.3%) were conventional adenocarcinomas (159, 29 and 13 cases were well, moderately and poorly differentiated, respectively) and 10 (4.7%) were mucinous type. Out of 211 cases, 171 were checked for lymph nodes metastasis and 64 were positive. There is a correlation between HER2 scores and differentiation, most score 3 cases being well differentiated (P<0.05). Conclusions: In patients with advanced colon cancer, surgery alone is not curative and other forms of therapy may be required to prolong patient survival. HER2 overexpression was found in some cases and this could be a guideline to new adjuvant therapy for these patients.

Background: Androgen receptors (ARs) are expressed in more than 70% of breast cancers (BCs) and have been implicated in BC pathogenesis. Some triple negative (TN)BC tumors express AR and may benefit from AR-targeted therapies. The aim of this study was to evaluate survival and the prevalence of AR expression and its correlation with other risk factors in triple negative BCs in women from Western Iran. Materials and Methods: In a retrospective study between 2009-2015, 41 patients with TNBC were referred to the Private Clinic of Oncology, Kermanshah city, Iran. ER, PR and AR-positive expression was defined as ${\geq}10%$ nuclear staining and also HER2 (2+), FISH was performed. Nuclear staining was considered representative for Ki67 and P53. The mean follow-up for the patients was 25 months. In this time, 5 patients died and 4 lost to follow-up were censored from survival analysis. Results: The mean age at diagnosis was 46.9 years (range, 24-71 years) and all patients were female. The OS rates for AR-positive and AR-negative patients were 90% and 85.1%, respectively, and the mean OS was 26.3 and 23.2 months. Therefore, there was no significant difference between the two groups (Hazard ratio: 0.580, 95% CI: 0.086-3.893, P=0.575). Conclusions: In TNBC patients, evaluation of AR status may provide additional information on prognosis and treatment. The results of studies showed that the prevalence AR expression may differ in the world and probably ethnicity can be an influencing factor.

Background: Cervical cancer is the second most common cancer among women in many populations. While the Pap smear is a well established screening test it suffers from both false-positive and false-negative results in diagnosis of cancers and precancerous states. In this study, immunocytochemistry of the P16 biomarker and HPV-PCR were compared for their diagnostic potential. Materials and methods: In the study, we obtained pairs of specimens from 45 women with cervical dysplasia. One sample was placed in a liquid-based solution, and processed for staining of sections with antibodies to P16. HPV-PCR was performed on the other and the results obtained were analyzed by T-test using SPSS v. 15. Results: Using HPV-PCR 71% of the samples were found to be infected with either HPV 16 or HPV 18, and the rate of infection did not have a statistically significant relationship with higher grades of dysplasia (p= 0.253). In contrast, with immunocytochemistry evaluation of P16, 64% of the specimens were positive, but the percentage of positive results significantly increased with higher grades of dysplasia (p= 0.0001). Conclusion: Employment of the P16 marker as an optional test might be preferable over HPV-PCR for cervical dysplasia in our geographical region.

Background: In breast cancer (BC), it has been suggested that nuclear overexpression of p53 protein might be an indicator of poor prognosis. The aim of the current study was to evaluate the expression of p53 BC in Kurdish women from the West of Iran and its correlation with other clinicopathology figures. Materials and Methods: In the present retrospective study, 231 patients were investigated for estrogen receptor (ER) and progesterone receptor (PR) positivity, defined as ${\geq}10%$ positive tumor cells with nuclear staining. A binary logistic regression model was selected using Akaike Information Criteria (AIC) in stepwise selection for determination of important factors. Results: ER, PR, the human epidermal growth factor receptor 2 (HER2) and p53 were positive in 58.4%, 55.4%, 59.7% and 45% of cases, respectively. Ki67 index was divided into two groups: 54.5% had Ki67<20% and 45.5% had Ki67 ${\geq}20%$. Of 214 patients, 137(64%) had lymph node metastasis and of 186 patients, 122(65.6%) had vascular invasion. Binary logistic regression analysis showed that there was inverse significant correlation between lymph node metastasis (P=0.008, OR 0.120 and 95%CI 0.025-0.574), ER status (P=0.006, OR 0.080, 95%CI 0.014-0.477) and a direct correlation between HER2 (P=005, OR 3.047, 95%CI 1.407-6.599) with the expression of p53. Conclusions: As in a number of studies, expression of p53 had a inverse correlation with lymph node metastasis and ER status and also a direct correlation with HER2 status. Also, p53-positivity is more likely in triple negative BC compared to other subtypes.
