  • Background: COX-2 has been shown to play an important role in the development of breast cancer and increased expression has been mooted as a poor prognostic factor. The purpose of this study was to investigate the relationship between COX-2 immunohistochemical expression and known predictive and prognostic factors in breast cancer in a routine diagnostic histopathology setting. Materials and Methods: Formalin-fixed paraffin-embedded tumour tissue of 144 no special type (NST) invasive breast carcinomas histologically diagnosed between January 2009 and December 2012 in Hospital Sultanah Bahiyah, Alor Setar, Kedah were immunostained with COX-2 antibody. COX-2 overexpression was analysed against demographic data, hormone receptor status, HER2-neu overexpression, histological grade, tumour size and lymph node status. Results: COX-2 was overexpressed in 108/144 (75%) tumours and was significantly more prevalent (87%) in hormone receptor-positive tumours. There was no correlation between COX-2 overexpression and HER2/neu status. Triple negative cancers had the lowest prevalence (46%) (p<0.05). A rising trend of COX-2 overexpression with increasing age was observed. There was a significant inverse relationship with tumour grade (p<0.05), prevalences being 94%, 83% and 66% in grades 1, 2 and 3 tumours, respectively. A higher prevalence of COX-2 overexpression in smaller size tumours was observed but this did not reach statistical significance. There was no relationship between COX-2 expression and lymph node status. Conclusions: This study did not support the generally held notion that COX-2 overexpression is linked to poor prognosis, rather supporting a role in tumorigenesis. Larger scale studies with outcome data and basic studies on cancer pathogenetic pathways will be required to cast further light on whether COX-2 inhibitors would have clinical utility in cancer prevention or blockage of cancer progression. In either setting, the pathological assessment for COX-2 overexpression in breast cancers would have an important role in the selection of cancer patients for personalized therapy with COX-2 inhibitors.

  • Purpose: To research the association between pre-treatment elevated platelet count and clinicopathologic characteristics in breast cancer (BC), as well as explore the relationship between pre-treatment elevated platelet count and HER2 status and prognosis of BC patients. Materials and Methods: A retrospective cohort of BC patients who were newly diagnosed or treated by surgery only and had pathological detection results and platelet values in the Department of Oncology, the First Affiliated Hospital of Liaoning Medical College were enrolled from 1/1/2008 until 31/12/2009, and followed up until 31/12/2014. Age, thrombocyte parameters before chemotherapy and/or radiotherapy, immunohistochemical (IHM) indexes, and regional lymph node (LN) involvement and progression-free survival (PFS) were recorded. Results: A total of 447 eligible subjects were included in this research. As we analyzed, for HER2, positive and negative, the incidence rates of elevated platelet count were 25.8% and 14.7% (P<0.05). In the Cox proportional hazards model both variables were independent risk factors for BC (for HER2, OR, 0.592, 95% confidence interval, CI, 0.355 to 0.985, P=0.044;f or PLT, OR, 0.998, 95% CI, 0.996 to 1.000, P=0.042). For ER, PR, Ki67 and LN involvement, the differences were not statistically significant (P>0.05). Conclusions: In this research, pre-treatment elevated level of platelet count demostrated a significantrelationship with HER2 amplification/overexpression, and both variables significantly influenced the prognosis of BC. However, elevated platelet count did not exhibit any association with ER, PR, Ki67 and LN involvement.

  • The c-erbB2/neu oncogene (alias HER2, NEU) encoding a tyrosine kinase receptor protein, the overexpression of which correlates with a more rapid progression and a worse prognosis in human breast cancer [1]. Otherwise, this gene is still poorly investigated in veterinary oncology [2,3]. To gain insight into the patterns of c-erbB2/neu status in canine mammary tumor, we constructed one such mammary tumor tissue microarray (TMA) from 60 tumors from our lab. This enabled the amplification of c-erbB2/neu oncogene of all 60 tumors to be simultaneously analyzed by chromogenic in situ hybridization (CISH). The aim of this study was to evaluate status of c-erbB2/neu oncogene in canine mammary tumors and to correlate this status with the differentiation grade of neoplasm. (omitted)

  • The purpose of this study is to investigate the relations between marital status incompatibility and the ways of dealing with marital conflict. Research was conducted by interview using questionnaire on 177 employed wives. Statistics used for data analysis were frequency distribution, percentage, t-test, chi-square test. 1) In resolving marital conflict four types of method are appeared, namely constructive method, passive method, evasion and physical violence. 2) Only physical violence of husband-to-wife of the four methods is related to status in-compatibility. That is the incidence rate of physical violence of husband-to-wife in incompatible couples is higher than that of compatible couples in conflict situations. 3) In case the wife's occupational status is high relative to her husband the incidence rate of physical violence of husband-to-wife is extremely high, but is significantly low in couples which are compatible in this status. 4) In case wife's status advance ent is controlled, there is significant relationship between status incompatibility and the method of conflict resolution by husband whose wife is status striver.

  • Background: Breast cancer (BC) is the most frequent cancer type, and the leading cause of death from cancer among women in Israel. The Bedouin-Arab (BA) population in southern Israel is characterized by a high rate of consanguinity, common hereditary disorders, and transition from a semi-nomadic, traditional society to a more sedentary and urbanized society. In this hospital-based study, the demographic and the clinicopathological characteristics of BC in BA were compared with Jewish patients. Materials and Methods: 85 BA patients treated at the Soroka Medical Center, Beer Sheba, during the years 2004-2012, were studied and compared with 180 consecutive Jewish patients treated during the year 2007. Clinicopathological features compared included age, menopausal state, number of births, a history of BC in first-degree relatives, tumor size (T), extent of lymph-node involvement (N), distant metastases (M), stage, grade, estrogen and progesterone receptor (ER/PR), and Her2 status. Types of treatment, relapse rate and site, as well as outcome were also studied. Cox's regression models were applied for studying disease-free, and overall survival. Results: Compared with Jewish patients, BA patients were younger (average age $49{\pm}12$ yrs vs $59{\pm}13$, p<0.001), had a lower rate of BC in first-degree relatives (p<0.001), and a larger number of births ($6{\pm}4.2$ vs $2.5{\pm}1.9$, p<0.001). BA patients had larger tumors (p=0.02), more extensive lymph-node involvement (p=0.002), and more advanced stage (p=0.003). Grade, ER, PR, and Her2 status were similar in the two ethnic groups. Relapse type was most commonly systemic in BA patients (p=0.05), and loco-regional in Jewish patients (p=0.02). Median survival was 63, and 35 months for Jewish and BA patients, respectively (log-rank test, p=0.02). In Cox multivariate analysis, stage and PR status (HR-0.14, p<0.0001; HR-3.11, p=0.046), but not ethnicity, influenced overall survival. Conclusions: BC presents a decade earlier, and with more advanced disease in BA compared with Jewish patients. Biologic parameters including grade, ER, PR, and Her2 status were similar in both groups. Although prognosis was worse in BA than in Jewish patients, it was affected only by stage and PR status, but not by ethnicity.

  • Purpose: Treatment options are limited after the failure of first-and second-line treatments in patients with HER2+ metastatic gastric cancer (mGC). The present study aimed to explore the efficacy, safety, and prognostic factors of apatinib efficacy as a third-line therapy for patients with human epithelial growth factor receptor 2-positive (HER2+) mGC. Materials and Methods: A total of 59 HER2+ mGC patients who received apatinib as third-line therapy were retrospectively enrolled in this two-center, single-arm, cohort study; the clinical response, survival data, and adverse events were retrieved. Results: The median progression-free survival (PFS) was 5.2 months (95% confidence interval [CI], 3.9-6.5), and the median overall survival (OS) was 8.2 months (95% CI, 6.6-9.8) Furthermore, forward stepwise multivariate Cox regression analysis showed that a higher Eastern Cooperative Oncology Group performance status score and multiple metastases were independently correlated with decreased PFS and OS (both P<0.05). The main adverse events were leukopenia (45.8%), hypertension (44.1%), thrombocytopenia (39.0%), hand-foot syndrome (37.3%), and elevated transaminase (33.9%). Grade 3 adverse events mainly included hypertension (5.1%) and neutropenia (5.1%); grade 4 adverse events did not occur. Conclusions: Apatinib is efficient and well tolerated in patients with HER2+ mGC as a third-line treatment, suggesting that it may be a candidate of choice for these patients.

  • This paper presents the concept for the development of a pet-type robot with an emotion engine. The pet-type robot named KOBIE (KOala roBot with Intelligent Emotion) is able to interact with a person through touch. KOBIE is equipped with tactile sensors on the body for interaction with a person through recognition of his/her touching behaviors such as "Stroke","Tickle","Hit". We have covered KOBIE with synthetic fur fabric in order to can make him/her feel affection as well. KOBIE is able to also express an emotional status that varies according to the circumstances under which it is presented. The emotion engine of KOBIE's emotion expression system generates an emotional status in an emotion vector space which is associated with a predefined needs and mood models. In order to examine the feasibility of our emotion expression system, we verified a changing emotional status in our emotion vector space by a touching behavior. We specially examined the reaction of children who have interacted with three kind of pet-type robots: KOBIE, PARO, AIBO for roughly 10 minutes to investigate the children's preference for pet-type robots.

  • The purpose of this study was to describe maternal social networks and to examine their relationships to maternal perceptions of parenting task difficulty. One hundred and thirty-three mothers of preschool children responded to a questionnaire indicating individuals in their networks, support functions, and perceptions of task difficulty. Mothers reported an average of 6.5 persons in their networks, including primarily with her own mother, the husband, mother-in-law, and sisters. While support was provided mainly by her husband and her own family members, the kinds of support varied depending on the person in networks. It was also found that support functions were different in terms of maternal job status, sex of the child, and the child's previous experience in day care or early childhood education settings. Emotional support from networks was significantly related to parenting task difficulty, especially in daily routine care. Mothers who perceived more emotional support from networks reported parenting to be less difficult.

  • Background: The three standard biomarkers used in breast cancer are the estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2). The Ki-67 index, a proliferative marker, has been shown to be associated with a poorer outcome, and despite absence of standardization of pathological assessment, is widely used for therapy decision making. We aim to study the role of the Ki-67 index in a group of Asian women with breast cancer. Materials and Methods: A total of 450 women newly diagnosed with Stage 1 to 3 invasive breast cancer in a single centre from July 2013 to Dec 2014 were included in this study. Univariable and multivariable logistic regression was used to determine the association between Ki-67 (positive defined as 14% and above) and age, ethnicity, grade, mitotic index, ER, PR, HER2, lymph node status and size. All analyses were performed using SPSS Version 22. Results: In univariable analysis, Ki -67 index was associated with younger age, higher grade, ER and PR negativity, HER2 positivity, high mitotic index and positive lymph nodes. However on multivariable analysis only tumour size, grade, PR and HER2 remained significant. Out of 102 stage 1 patients who had ER positive/PR positive/HER2 negative tumours and non-grade 3, only 5 (4.9%) had a positive Ki-67 index and may have been offered chemotherapy. However, it is interesting to note that none of these patients received chemotherapy. Conclusions: Information on Ki67 would have potentially changed management in an insignificant proportion of patients with stage 1 breast cancer.
