    OBJECTIVE: The objective of this study is to determine the quality of life among breast cancer patients in Yemen based on socio-demographic and clinical characteristics.

    METHODOLOGY: This study was designed as a cross-sectional study. The data collected from 106 female breast cancer patients who were chosen for recruitment from the outpatient in National Oncology Centre (NOC), Sana'a, Yemen from November 2008 to June 2011. Questionnaires were distributed to the patients during their visit to the outpatient clinics in the center. The instrument of this study consists of two parts: Socio-demographic and the Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire. Regarding data analysis, means and SD of subscales were evaluated for descriptive purpose. Analysis of variance (ANOVA) was performed to compare the three groups regarding QOL subscales. Whereas, independent t-test was performed for comparing two groups regarding QOL subscales. Multiple linear regression using backward analysis was performed to obtain the final model for each domain. The final model was chosen depending on R2 and the p value of the model. A p value less than 0.05 is considered statistically significant.

    RESULTS: A total number of 106 breast cancer patients were participated in this study. The majority of them were uneducated, unemployed with normal weight and had middle income (60.4%; 95.3%; 59.4%, 46.2%; respectively). As for clinical characteristics of the study participants; the majority of them had had no family history of breast cancer, have been diagnosed at least 2 years, were diagnosed at grade 3 and size of tumor greater than 2 cm (88.7%, 66.0%, 35.8%, 73.6%; respectively). The majority of them underwent mastectomy, radiotherapy, chemotherapy and tamoxifen therapy (85.8%, 63.2%, 94.3% and 62.3%; respectively). For univariate analysis, the present study has identified several factors includes family monthly income, BMI, educational status, years after diagnosis, histological grade radiotherapy and surgery that influence the QOL of breast cancer patients in Yemen. For multivariate analysis, years after diagnosis, family monthly income and radiotherapy were significantly associated with total QOL of the breast cancer patients (p=0.01, p=0.023, p=0.039; respectively).

    CONCLUSION: Family monthly income, BMI, educational status, years after diagnosis, histological grade radiotherapy and surgery were significantly influence the QOL of breast cancer patients in Yemen, in univariate analysis. For multivariate analysis, years after diagnosis, family monthly income and radiotherapy were significantly associated with total QOL of the breast cancer patients.

    Breast cancer may be classified into luminal A, luminal B, HER2+/ER-, basal-like and normal-like subtypes based on gene expression profiling or immunohistochemical (IHC) characteristics. The main aim of the present study was to classify breast cancer into molecular subtypes based on immunohistochemistry findings and correlate the subtypes with clinicopathological factors. Two hundred and seventeen primary breast carcinomas tumor tissues were immunostained for ER, PR, HER2, CK5/6, EGFR, CK8/18, p53 and Ki67 using tissue microarray technique. All subtypes were significantly associated with Malay ethnic background (p=0.035) compared to other racial origins. The most common subtypes of breast cancers were luminal A and was significantly associated with low histological grade (p<0.000) and p53 negativity (p=0.003) compared to HER2+/ER-, basal-like and normal-like subtypes with high histological grade (p<0.000) and p53 positivity (p=0.003). Luminal B subtype had the smallest mean tumor size (p=0.009) and also the highest mean number of lymph nodes positive (p=0.032) compared to other subtypes. All markers except EGFR and Ki67 were significantly associated with the subtypes. The most common histological type was infiltrating ductal carcinoma, NOS. Majority of basal-like subtype showed comedo-type necrosis (68.8%) and infiltrative margin (81.3%). Our studies suggest that IHC can be used to identify the different subtypes of breast cancer and all subtypes were significantly associated with race, mean tumor size, mean number of lymph node positive, histological grade and all immunohistochemical markers except EGFR and Ki67.

    BACKGROUND: Breast cancer is the commonest cancer affecting women world wide. Breast cancer is a leading cause of cancer related mortality in Asian countries. Management of breast cancer depends on several tumour-related and patient related factors. HER-2/neu over-expression has been associated with a poor prognosis in breast cancer. We assessed HER-2/neu over expression pattern in unselected breast cancer cases in terms of clinico-pathologic parameters to identify any associations between them.

    METHODS: Two hundred cases of breast cancer were evaluated at Advanced Medical and Dental Institute and Hospital Kepala Batas from 2002 to 2007. HER-2/neu status was confirmed in breast cancer tissues by immunohistochemistry. Immunohistochemical expression of HER-2/neu was evaluated according to the published scoring guidelines of the 'Hercep Test' (Dako, Carpinteria, CA). Data were analysed to identify any association between HER-2/neu and clinico-pathologic parameters.

    RESULTS: HER-2/neu over expression was found in 63 (31.5%) tumours out of 200. When assessed for various age groups no significant association was found. However, a high percentage (75%) of over-expression was noted in the 81-85 years age group. No association was found with different racial groups (Malay, Chinese and Indians), with lymph node status or with grade of tumour. However a positive association was observed with oestrogen receptor and progesterone receptor expression.

    CONCLUSION: There was no association between HER-2/neu over expression and age, race, lymph node status or tumor grade. However a positive association was found with oestrogen and progesterone receptor status.

    BACKGROUND: Locoregional recurrence after mastectomy for breast cancer may predict distant recurrence and mortality. This study examined the pattern and rates of post-mastectomy locoregional recurrence (PMLRR), survival outcome and prognostic factors for isolated PMLRR (ILR) in a breast cancer cohort in University of Malaya Medical Center (UMMC).

    METHODS: We studied 522 patients who underwent mastectomy between 1998 and 2002 and followed them up until 2008. We defined PMLRR as recurrence to the axilla, supraclavicular nodes and or chest wall. ILR was defined as PMLRR occurring as an isolated event. Prognostic factors for locoregional recurrence were determined using the Cox proportional hazards regression model.

    RESULTS: The overall PMLRR rate was 16.4%. ILR developed in 42 of 522 patients (8.0%). Within this subgroup, 25 (59.5%) remained disease free after treatment while 17 (40.5%) suffered disease progression. Univariate analyses identified race, age, size, stage, margin involvement, lymph node involvement, grade, lymphovascular invasion and ER status as probable prognostic factors for ILR. Cox regression resulted in only stage III disease and margin involvement as independent prognostic factors. The hazard of ILR was 2.5 times higher when the margins were involved compared to when they were clear (aHRR 2.5; 95% CI 1.3 to 5.0). Similarly, compared with stage I those with Stage II (aHRR 2.1; 95%CI 0.6 to 6.8) and stage III (aHRR 4.6; 95%CI 1.4 to 15.9) had worse prognosis for ILR.

    CONCLUSION: Margin involvement and stage III disease were identified to be independent prognostic factors for ILR. Close follow-up of high risk patients and prompt treatment of locoregional recurrence were recommended.

    Two hospital-based breast cancer databases (University Malaya Medical Center, Malaysia [n = 1513] and National University Hospital, Singapore [n = 2545]) were merged into a regional registry of breast cancer patients diagnosed between 1990 and 2007. A review of the data found 51% of patients diagnosed before the age of 50 years. and 72% percent of the women were Chinese followed by Malays (16%), Indians (8%), and other races (4%). Median tumor size at presentation was 26 mm and about 25% of patients presented with TNM stage III or IV disease. Most tumors were of ductal histology (87%). Fifty-seven percent of tumors were estrogen receptor positive and 40% were poorly differentiated. Of those patients who had surgery, 70% had mastectomy while 30% had breast conserving surgery. Overall, chemotherapy was administered to 56% of patients and hormonal treatment to 60%. Five-year overall survival was 82.5% in patients with TNM stage 0 to stage II cancer, and 30.2% in those with later stages.

    Estrogen receptor (ER) positive rates in breast cancer may be influenced by grade, stage, age and race. This study reviews the ER positive rates over a 15-year period at the University Malaya Medical Centre, Kuala Lumpur, Malaysia. Data on ER status of 3557 patients from 1994 to 2008 was analyzed. ER status was determined by immunohistochemistry with a cut-off point of 10%. ER positivity increased by about 2% for every 5-year cohort, from 54.5% in 1994-1998 to 58.4% in 2004-2008. Ethnicity and grade were significantly associated with ER positivity rates: Malay women were found to have a higher risk of ER negative tumors compared with Chinese women. Grade 1 cancers were nine times more likely to be ER positive compared with grade 3 cancers. In summary, the proportion of ER positive cancers increased with each time period, and ethnicity and grade were independent factors that influenced ER positive rates.

    BACKGROUND: The ideal method for diagnosis of breast cancer is debatable.
    METHODS: The methods of diagnosis of 436 new cases of breast adenocarcinoma presenting from Jan 2005 till Dec 2006 at the University Malaya Medical Centre (UMMC) were examined in this study.
    RESULTS: A total of 388 cases presented to the breast unit in UMMC primarily and 48 cases were diagnosed in non-breast units in other hospitals and referred for management. Fine needle aspiration cytology (FNAC) was the commonest mode of initial diagnosis in 278 cases followed by core needle biopsy and surgical excision. In UMMC, FNAC was the commonest initial method (68.3%) compared to cases diagnosed outside UMMC, where 37.5% of cases were diagnosed by excision. Tumours less than 2cm were more likely to be diagnosed by excision biopsy.
    CONCLUSION: The biopsy method used to confirm the diagnosis is influenced by where the patient first presents, and by the size of the tumour.

    Chromatin morphologies in human breast cancer cells treated with an anti-cancer agent are analyzed at their early stage of programmed cell death or apoptosis. The gray-level images of nuclear chromatin are modelled as random fields. We used two-dimensional isotropic generalized Cauchy field to characterize local self-similarity and global long-range dependence behaviors in the image spatial data. Generalized Cauchy field allows the description of fractal behavior inferred from fractal dimension and the long-range dependence inferred from correlation exponent to be carried out independently. We demonstrated the usefulness of locally self-similar random fields with long-range dependence for modelling chromatin condensation.

    Neuroendocrine carcinomas of the breast are uncommon tumors known to occur in the elderly. While focal neuroendocrine differentiation may be noted in many ductal and lobular carcinomas, the term neuroendocrine carcinoma is to be applied when more than 50% of the tumor shows such differentiation. This case report details the cytological features of a neuroendocrine carcinoma that was encountered in our hospital. The fine needle aspiration (FNA) smears showed discohesive polygonal cells with abundant cytoplasm, many of which contained eosinophilic granules located at one pole. Histology of the mastectomy and axillary lymph nodes specimen from this patient showed features of neuroendocrine carcinoma--solid type, with metastasis, confirmed with immunohistochemistry. The patient is disease free seven months after surgery. This case highlights the need to closely observe cytological details to identify this rare tumor that may otherwise appear to be invasive duct carcinoma--not otherwise specified on FNA. The implications of diagnosing neuroendocrine differentiation for prognosis and management are also discussed.

    The HER2 codon Ile655Val and Cyclin D1 (CCND1) G870A polymorphisms were analyzed in a hospital-based Malaysian population using PCR-RFLP method. Peripheral blood samples were collected from 230 breast cancer patients, and 200 normal and healthy women who had no history of breast disease or breast cancer. We evaluated the association between HER2 or CCND1 polymorphisms and breast cancer risk, and clinico-pathological parameters in the population. The genotype and allele frequencies of HER2 (P=0.163 vs P=0.0622) and CCND1 (P=0.377 vs P=0.284) polymorphisms were not significantly different between the breast cancer cases and normal subjects, respectively. Women who were Ile/Val heterozygotes (OR=1.48; 95% CI, 0.91-2.43), Val/Val homozygotes (OR=1.93; 95% CI, 0.51-7.77) and carriers of Val allele genotype (OR=1.53; 95% CI, 0.95-2.45) were not significantly associated with increased breast cancer risk. Similarly, women who were homozygous (OR=1.34; 95% CI, 0.77-2.34) or heterozygous (OR=0.98; 95% CI, 0.60-1.60) for A allele, or carriers of A allele genotype (OR=1.10; 95% CI, 0.70-1.73) were not associated with breast cancer risk. Analysis on clinico-pathological parameters showed that Val allele genotype was significantly correlated with nodal metastases but A allele genotype was not associated with any of the variables. Our findings suggest that the polymorphic alleles of HER2 and CCND1 may not play an important role as genetic markers for breast cancer risk, but presence of Val allele may be useful for tumor prognosis.

    Xanthorrhizol is a natural sesquiterpenoid compound isolated from the rhizome of Curcuma xanthorrhiza Roxb (Zingiberaceae). Xanthorrhizol was tested for a variety of important pharmacological activities including antioxidant and anti-inflammatory activities. An antiproliferation assay using the MTT method indicated that xanthorrhizol inhibited the proliferation of the human breast cancer cell line, MCF-7, with an EC50 value of 1.71 microg/ml. Three parameters including annexin-V binding assay, Hoechst 33258 staining and accumulation of sub-G1 population in DNA histogram confirmed the apoptosis induction in response to xanthorrhizol treatment. Western-blotting revealed down-regulation of the anti-apoptotic bcl-2 protein expression. However, xanthorrhizol did not affect the expression of the pro-apoptotic protein, bax, at a concentration of 1 microg/ml, 2.5 microg/ml and 5 microg/ml. The level of p53 was greatly increased, whilst PARP-1 was cleaved to 85 kDa subunits, following the treatment with xanthorrhizol at a dose-dependent manner. These results, thereby, suggest that xanthorrhizol has antiproliferative effects on MCF-7 cells by inducing apoptosis through the modulation of bcl-2, p53 and PARP-1 protein levels.

    OBJECTIVE: To analyze the cytologic features of nipple discharge and fine needle aspiration (FNA) cytologic smears from breast lesions reported as showing papillary features and to correlate them with histopathologic features.

    STUDY DESIGN: The study group consisted of FNA smears and/or nipple discharge smears from 65 breast lesions diagnosed on cytology as duct papilloma, papillary lesion, fibrocystic condition, fibroadenoma, papillary neoplasm or papillary carcinoma. Cytomorphologic features assessed included cellularity, cell pattern (clusters, papillary, 3-dimensionality, etc.) and cell characteristics (monomorphism, pleomorphism, apocrine change, plasmacytoid features). Histological material was available for review and cytohistologic correlation in all cases.

    RESULTS: Forty-six specimens were FNA smears, and 16 were nipple discharge smears; in 3 cases FNA and nipple discharge cytologic smears were available for review. Cytologic study could predict the presence of a papillary pattern in all neoplasms with pure or focal papillary differentiation. There was an overlap in cytomorphologic features between papillary and nonpapillary benign lesions as well as between benign and malignant papillary neoplasms. Frank blood in the aspirate, cell dissociation and atypia, however, were more frequent in the last.

    CONCLUSION: Overlap of cytologic features in nonneoplastic and neoplastic benign papillary lesions and between benign and malignant papillary neoplasms necessitates histologic evaluation in all cases diagnosed as papillary on cytology. Since 49.2% of lesions showing papillary features on cytology prove to be malignant, all cases reported as papillary on cytology should be excised urgently for histologic assessment.

    To type breast carcinomaon on fine needle aspiration cytology (FNAC) material and correlate the results with histologic typing, to grade breast carcinoma on FNAC material and correlate the findings with Bloom-Richardson histologic grading, and to determine the estrogen receptor (ER) status in cases of breast carcinoma by immunocytochemical (ICC) staining of FNA cytologic material and correlate the findings with ER status, as determined by immunohistochemical (IHC) staining of tissue sections.

    STUDY DESIGN: Seventy-seven cases of breast carcinoma diagnosed on FNAC formed the basis of this study. Typing was done in all cases on the basis of cytologic features and grading in 62. (Fifteen cases were special types of breast carcinoma). In all cases, ER status was determined by immunostaining of cytologic smears. Results of tumor typing, grading and ER status on cytologic material were compared with the results of histologic typing, grading and immunostaining of histologic material obtained from mastectomy or wide excision specimens.

    RESULTS: Tumor typing was accurate in 73 of 77 cases (94.8%). Fifteen of 18 cases that were cytologically grade 3 were confirmed on histology, while 3 proved to be grade 2. Of 40 cytologic grade 2 cases, 26 were confirmed on histology, while 14 cases were grade 3. Three of 4 cytologically grade 1 cases were confirmed on histology while 1 was grade 2. The overall accuracy for cytologic grading was 71% (44 of 62 cases). Thirty-seven of 40 ER-positive cases (92.5%) were labeled ER positive on ICC. One case was ER negative on cytology, while in 2 cases the cellularity of the cytologic smear was insufficient to assess ER expression. Thirty-seven cases were negativefor ER on IHC. Nine of these showed ER positivity on ICC, 26 were negative, and 2 had cellularity that was inadequate for assessment of ER. Sensitivity and specificity rates for ER detection on ICC were 97.4% and 74.3%, respectively.

    CONCLUSION: Tumor typing, grading and evaluation of ER status on FNA C material in breast carcinomas are simple, quick and moderately reliable techniques that compare and correlate favorably with histologic typing, grading and ER status on IHC.

    BACKGROUND: Leiomyosarcoma of the breast is a rare neoplasm. We present a case of primary leiomyosarcoma of the breast in a middle-aged female in whom fine needle aspiration cytologic features suggested sarcoma.

    CASE: A 55-year-old female presented with a rapidly growing breast lump of 1 month's duration. On examination, an ulcerating, 12 x 10 cm tumor was seen involving the lower medial and lateral quadrants of the right breast. Fine needle aspiration cytology showed variably sized, dissociated and loosely clustered polygonal, plump and spindle cells with pale blue cytoplasm and vesicular nuclei that were round, oval or irregular. Occasional giant forms and nucleolated and mitotic cells were present. A single cluster of benign ductal cells was seen. The tumor cells did not express immunocytologic reactivity to estrogen receptor protein. A cytologic diagnosis of sarcoma was given with differential diagnoses of metaplastic carcinoma and malignant phyllodes tumor. Histologic study established the diagnosis of leiomyosarcoma. Leiomyosarcoma of the breast shows fine needle aspiration cytologic features of sarcoma, but specific tumor typing may not be possible, especially when the cytologic material is inadequate for ancillary staining required to distinguish leiomyosarcoma from metaplastic carcinoma and malignant phyllodes tumor.

    Prebiopsy localization of impalpable breast lesions (IBL) assures removal of suspicious mammographically detected lesions. Specimen radiograph of the excised specimen is mandatory to confirm complete excision. The aim of this study was to audit our series of percutaneous hookwire localization and to determine the positive biopsy rate of the mammographically detected impalpable breast lesion in our center. Thirty-eight patients with suspicious IBL underwent excision biopsy under mammographic localization in our unit from late February 1998 to May 2003. The excised specimen is immobilized and compressed within the Transpec device. This device incorporates a reference grid visible in the specimen radiograph. Hence, the target lesion marked in the reference grid of the specimen radiograph will allow precise examination and exact localization of the suspicious lesion by the pathologist. The positive biopsy rate for malignant lesion was 26.3%, the majority fall in the range of 40-59 age group. Thirty-two (84.2%) of the patients had clustered micro-calcifications, 4 (10.5%) had impalpable mass lesions and in 2 (5.3%) spiculated lesions were seen on the preoperative mammogram. Mammographic feature of clustered micro-calcification accounts for all the malignant lesions in our series. Utilization of Transpec device has shown to be practical, reliable and cost effective in the management of IBL. Nonetheless, it should be emphasized that optimal specimen radiography and pathological correlation requires close cooperation between radiologist, surgeon and pathologist.

    Tumor-associated macrophages play a crucial role in breast cancer progression and tumor angiogenesis. However, evaluation of tumor-associated macrophages incorporating their histological locations is lacking. The aim of this study was to clarify whether macrophages in tumor stroma and macrophages in tumor cell nests have distinctive properties in relation to pertinent breast cancer clinicopathological parameters and tumor angiogenesis. In 94 human invasive breast ductal carcinomas, tumor-associated macrophages were immunostained with anti-CD68 antibody and counted or graded according to these histological locations. Microvessels were immunostained with anti-CD34 antibody and counted for microvessel density. We found that the presence of tumor stromal and tumor nest macrophages was closely correlated (p = 0.001). Both tumor stromal and tumor nest macrophages were associated with mitotic count (p = 0.001 and p = 0.037, respectively). However, only higher tumor stromal macrophage grades were associated with higher tumor grades (p = 0.004) and negative estrogen receptor status (p = 0.007). Multivariate analysis showed that tumors with a high mitotic count score (score 3 vs. scores 1 and 2) had a higher tumor stromal macrophage density (Grades III and IV) when adjusted for tumor size, tubule formation, and estrogen receptor status (odds ratio 3.41, p = 0.010). The tumor nest macrophage count significantly correlated with the microvessel density (p

    BACKGROUND: Complementary and alternative medicine (CAM) use has become increasingly popular among patients with cancer. The purposes of this study were to compare the QOL in CAM users and non-CAM users and to determine whether CAM use influences QOL among breast cancer patients during chemotherapy.

    METHODOLOGY: A cross-sectional survey was conducted at two outpatient chemotherapy centers. A total of 546 patients completed the questionnaires on CAM use. QOL was evaluated based on the European Organization for Research and Treatment of Cancer (EORTC) core quality of life (QLQ-C30) and breast cancer-specific quality of life (QLQ-BR23) questionnaires.

    RESULTS: A total of 70.7% of patients were identified as CAM users. There was no significant difference in global health status scores and in all five subscales of the QLQ C30 functional scales between CAM users and non-CAM users. On the QLQ-C30 symptom scales, CAM users (44.96±3.89) had significantly (p = 0.01) higher mean scores for financial difficulties than non-CAM users (36.29±4.81). On the QLQ-BR23 functional scales, CAM users reported significantly higher mean scores for sexual enjoyment (6.01±12.84 vs. 4.64±12.76, p = 0.04) than non-CAM users. On the QLQ-BR23 symptom scales, CAM users reported higher systemic therapy side effects (41.34±2.01 vs. 37.22±2.48, p = 0.04) and breast symptoms (15.76±2.13 vs. 11.08±2.62, p = 0.02) than non-CAM users. Multivariate logistic regression analysis indicated that the use of CAM modality was not significantly associated with higher global health status scores (p = 0.71).

    CONCLUSION: While the findings indicated that there was no significant difference between users and non-users of CAM in terms of QOL, CAM may be used by health professionals as a surrogate to monitor patients with higher systemic therapy side effects and breast symptoms. Furthermore, given that CAM users reported higher financial burdens (which may have contributed to increased distress), patients should be encouraged to discuss the potential benefits and/or disadvantages of using CAM with their healthcare providers.

    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.
