Abstract
BACKGROUND Breast cancer is the most common cancer in females. The immune system has a crucial role in the fight against cancer. B and T cells, the two main components of the adaptive immunity, are critical players that specifically target tumor cells. However, B cells, in contrast to T cells, and their role in cancer inhibition or progression is less investigated. Accordingly, in this study, we assessed and compared the frequency of naïve and different subsets of memory B cells in the peripheral blood of patients with breast cancer and healthy women. RESULTS We found no significant differences in the frequencies of peripheral CD19+ B cells between the patients and controls. However, there was a significant decrease in the frequency of CD19+IgM+ B cells in patients compared to the control group (P=0.030). Moreover, the patients exhibited higher percentages of atypical memory B cells (CD19+CD27‒IgM‒, P=0.006) and a non-significant increasing trend in switched memory B cells (CD19+CD27+IgM‒, P=0.074). Further analysis revealed a higher frequency of atypical memory B cells (aMBCs) in the peripheral blood of patients without lymph node involvement as well as those with a tumor size greater than 2cm or with estrogen receptor (ER) negative/progesterone receptor (PR) negative tumors, compared with controls (P=0.030, P=0.040, P=0.031 and P=0.054, respectively). CONCLUSION Atypical memory B cells (CD19+CD27‒IgM‒) showed a significant increase in the peripheral blood of patients with breast cancer compared to the control group. This increase seems to be associated with tumor characteristics. Nevertheless, additional research is necessary to determine the precise role of these cells during breast cancer progression.

Abstract
BACKGROUND Interleukin-21 (IL-21) is produced by various cell types inducing positive and negative effects in immunity against tumors. OBJECTIVE To investigate the expression of IL-21 by CD4+T and IL-21 receptor (IL-21R) by B lymphocytes isolated from breast-tumor draining lymph nodes (TDLNs). METHODS Fresh lymph node samples were obtained from 45 patients with breast cancer. To assess IL-21 expression, mononuclear cells were briefly stimulated whereas IL-21R expression was assessed in unstimulated B cells. Cells were stained with antibodies for CD4, IL-21, CD19 and IL-21R and acquired by flow cytometry. RESULTS The frequency of IL-21+CD4+T cells did not show significant association with disease parameters. However, the geometric mean fluorescence intensity (gMFI) of IL-21 in CD4+T cells was significantly lower in patients with grade III tumor than grade I + II (P = 0.042). In non-involved LNs, the intensity of IL-21 was significantly higher in patients with stage II compared with stage III (P = 0.038) and correlated negatively with the number of involved LNs. The frequency of IL-21R+CD19+B cells was significantly higher in grade III than grade I + II (P = 0.037). CONCLUSION The higher intensity of IL-21 in CD4+T cells showed association with good prognosticators in breast cancer and warrants further investigation of the role played by IL-21 in immunity against breast cancer.

Abstract
Tumor necrosis factor-alpha (TNF-α) is mostly known as a soluble cytokine. However, this study focused on its membranous form whose significance is rarely investigated in antitumor immunity. Herein, we assessed the expression of both membranous and intracellular forms of TNF-α (m/icTNF-α) in the lymphocytes derived from breast cancer-draining lymph nodes. CD4+T cells were the main subset expressing mTNF-α with the highest intensity, whereas icTNF-α expression was most intense in CD8+T cells. An inverse correlation was seen between the frequency of mTNF-α and the expression intensity of this cytokine in B cells. In the clinical context, the higher intensity of mTNF-α expression in CD19+ cells correlated with poor prognosticators, while the frequency of mTNF-α+CD19+ cells showed a reverse correlation with the number of involved lymph nodes. The two forms of TNF-α did not show similar associations with cancer parameters, which highlights the complex role of this cytokine in breast cancer immunity.

Abstract
Tumor Necrosis Factor Receptor 2 (TNFR2) is one of the receptors of TNF-α, which is expressed on various cell types. TNFR2 signaling has a balancing role between regulatory and effector functions of T cells. Herein, we investigated the expression of TNFR2 on regulatory T cells (Tregs) and non-Tregs in breast tumor-draining lymph nodes. Mononuclear cells were isolated from 16 axillary lymph nodes, and the expressions of TNFR2, Foxp3 and CD25 were assessed in CD4+ T cells by flow cytometry. Our results showed that the majority of TNFR2+CD4+ T cells were Foxp3-CD25-. However, the percentage of TNFR2+ cells was significantly higher in Foxp3+CD25+CD4+ Tregs compared to Foxp3-CD25-CD4+, Foxp3+CD25-CD4+, and Foxp3-CD25+CD4+ T cell subsets. Among these subsets, Foxp3+CD25+TNFR2+CD4+ T cells were found to have the highest intensity of TNFR2 expression. The intensity of Foxp3 expression in Foxp3+CD25+TNFR2+CD4+ Treg cells was significantly higher than in their TNFR2- counterpart. Collectively, we showed that most of TNFR2+CD4+ T lymphocytes were Foxp3-CD25-, while the majority of Foxp3+CD25+CD4+ Tregs were TNFR2+, and they expressed TNFR2 with the highest intensity. This report highlights the importance of TNFR2 expression on Tregs and paves the way for further investigation of the effects of TNF-α on the suppressive activity of Tregs in the tumor microenvironment.

Abstract
AIMS B cells can promote or inhibit immune responses against breast cancer. We investigated changes in the frequency of B cells with stimulatory or regulatory capacity in breast tumor draining lymph nodes during cancer progression. MAIN METHODS We isolated mononuclear cells from fresh axillary lymph nodes (LNs) of 44 patients with breast cancer and stained lymphocytes with antibodies against CD19, CD80, CD86, CD39 and CD73. To assess programmed death-1 (PD-1) and PD-ligand 1 (PD-L1) expression, lymphocytes were briefly stimulated, stained for CD19, PD-1 and PD-L1, and examined with flow cytometry. KEY FINDINGS The frequency of CD80+ B cells was higher in nonmetastatic lymph nodes, while the percentage of CD86+ B cells showed a positive relationship with higher tumor grade and higher numbers of involved LNs. A small proportion of unstimulated B cells expressed PD-1 or PD-L1 but these molecules were rapidly upregulated on B cells following activation. The frequency of stimulated PD-L1+ B cells showed an inverse association with estrogen and progesterone receptor expression and a nonsignificant positive association with tumor grade. In addition, the percentage of unstimulated PD-1+ B cells was higher in patients with higher-grade tumors. CD73 expression on B cells was associated with lower numbers of involved LNs, and the frequency of CD39+ B cells was higher in patients with larger tumors. SIGNIFICANCE CD86+, CD39+, PD-1+ and PD-L1+ B cells showed associations with poor prognostic factors, therefore their potential role in the suppression of the immune responses against breast cancer should be evaluated in greater detail.

Abstract
BACKGROUND A T cell subtype with the CD4+CD25-FoxP3+ phenotype was recently described. We aimed to investigate the frequency of these cells and their ability to produce cytokines in tumor-draining lymph nodes from patients with breast cancer (BC). MATERIALS AND METHODS Mononuclear cells from lymph nodes of 20 patients with BC were activated and stained for appropriate markers. The cells were assayed with four-color flow cytometry. RESULTS A very small fraction of CD4+CD25-FoxP3+ cells produced cytokines at levels that were significantly lower than in the regulatory (CD4+CD25+FoxP3+) and effector cell (CD4+CD25+FoxP3-) subpopulations. The expression of IFNγ and IL-2 in the CD4+CD25-FoxP3+ subset was significantly higher than in Treg cells, but lower than in the effector subset. Conversely, IL-22 expression in Treg cells was significantly higher than in the CD4+CD25-FoxP3+ subpopulation. The expression of IL-10 in the CD4+CD25-FoxP3+ subset was also significantly higher than in effector cells. CONCLUSION We suggest that CD4+CD25-FoxP3+ cells in patients with BC are exhausted cells with an intermediate phenotype between effector and regulatory cells.

Abstract
Context Through the expression of different immunomodulatory molecules, mesenchymal stem cells (MSCs) play a significant role in the regulation of immune responses against tumor cells. Herein, the expression of major histocompatibility complex class I polypeptide-related sequence B (MIC B) as an immunomodulatory molecule was investigated on adipose-derived stem cells (ASCs) isolated from breast cancer patients (Stage II and III) and healthy individuals. Materials and Methods ASCs were isolated enzymatically, and the expression of MIC B was measured using quantitative real-time polymerase chain reaction method before and after treatment with interferon γ (IFN-γ). The concentration of MIC B in the supernatant of ASCs and also sera of breast cancer and normal individuals were determined using ELISA method. Results The expression of MIC B in normal ASCs and Stage II ASCs was higher than Stage III ASCs. However, after treatment with IFN-γ expression of MIC B in ASCs was conversely changed as cancer ASCs showed approximately 3.5 fold higher expression of MIC B compared to normal ASCs. The mRNA expression of MIC B in Stage III, Stage II, and normal ASCs showed 61 (P = 0.02), 13 (P = 0.01) and 3 (P > 0.05) fold higher expression after stimulation with IFN-γ compared to cells with no stimulation. Conclusion Expression of MIC B and upregulation of this molecule in response to IFN-γ in cancer ASCs draw attention to the effective role of MSCs in the tumor microenvironment. However, more studies will be needed to further elucidate Natural-killer Group 2, member D (NKG2D) ligands-dependent immunomodulatory roles of ASCs in the tumor progression.

Abstract
PURPOSE In recent years, the prognostic/predictive significance of tumor infiltrating lymphocytes (TILs) has become a topic of interest. Here, we aimed to evaluate the prognostic significance of CD3+, CD8+, CD45RO+ and Foxp3+ TILs in breast cancer, as well as the relation of these markers to other clinicopathological features of this disease. METHODS FFPE tumor samples from 94 females with invasive ductal carcinoma of the breast were retrospectively selected and immunohistochemically assessed for CD3, CD8, CD45RO and Foxp3 expression. Digital photos were acquired from the center (CT) and invasive margins (IM) of the tumors, after which positive cells were counted using ImageJ software. RESULTS We found that greater infiltrations of target lymphocyte subpopulations were associated with TNM stage III, lymph node metastasis, high histological grade, ER negativity and HER2 positivity. The ratios of CD8+ cytotoxic T cells to CD3+, CD45RO+ and Foxp3+ TILs were found to be relatively higher in tumors exhibiting the aforementioned characteristics. In univariate survival analyses, CD8+ TILs in the IM and total CD45RO+ TILs were found to be significantly associated with overall survival (OS). Infiltration of CD45RO+ TILs in the CT and lymph node status were variables that significantly correlated with disease-free survival (DFS). Multiple Cox regression analyses revealed independent significant prognostic effects of total CD45RO+ TILs and lymph node status (HR of 3.24 and 3.19, respectively) in predicting OS. Infiltration of CD45RO+ TILs in the CT (HR 3.12) and lymph node status (HR 3.15) also exhibited significant prognostic effects on DFS. CONCLUSION From our data we conclude that CD45RO+ TILs serve as prognostic factors for predicting OS and DFS of breast cancer patients.

Abstract
Adipose-derived mesenchymal stem cells (ASCs) are known to have immunomodulatory properties through soluble factors or by direct cell-to-cell contact. This study aimed to assess the expression of HLA-G and IDO activity in breast cancer and normal ASCs and to see whether ASC is capable of modulating both tumor cells and immune system cells in vitro. ASCs were enzymatically isolated from 15 breast cancer patients and 10 normal individuals. Then they were cultured, and the impact of their conditioned media on the movement of the MDA-MB-231 breast cancer cell line was studied in wound healing scratch assay. Next, PBLs from the peripheral blood of normal individuals were separated and co-cultured with breast cancer and normal ASCs. PBLs proliferation and apoptosis were assessed using CFSE labeling dye and annexin V/7AAD staining, respectively. IDO activity and HLA-G protein expression in ASCs were examined using kynurenine assay and Western blotting, respectively. Tumor-derived ASCs, especially those from higher stages of breast cancer, have stronger effects on the proliferation and movement of MDA-MB-231 cells than normal ASCs (P-value < 0.05). Apoptosis in PBLs increased in the presence of ASCs compared to PBLs cultured alone (P-value < 0.05). In contrast, necrosis of PBLs decreased in the presence of ASCs compared to apoptosis in these cells (P-value < 0.001). Collectively, ASCs may have strategic effects on both tumor cells and cells of the immune system in the tumor microenvironment, resulting in tumor development, growth, and metastasis.

Abstract
OBJECTIVE Adipose derived stem cells (ASCs), as one of the important stromal cells in the tumor microenvironment, are determined with immunomodulatory effects. The principle aim of this study was to evaluate the immunosuppressive effects of ASCs on natural killer (NK) cells. MATERIALS AND METHODS In this experimental study, we assessed the expressions of indolamine 2, 3-dioxygenase (IDO1), IDO2 and human leukocyte antigen-G5 (HLA-G5) in ASCs isolated from breast cancer patients with different stages as well as normal individuals, using quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Immunomodulatory effects of ASCs on the expression of CD16, CD56, CD69, NKG2D, NKp30, NKG2A and NKp44 was also assessed in peripheral blood lymphocytes (PBLs) by flow-cytometry. RESULTS Our result showed that IDO1, IDO2 and HLA-G5 had higher mRNA expressions in ASCs isolated from breast cancer patients than those from normal individuals (P>0.05). mRNA expression of these molecules were higher in ASCs isolated from breast cancer patients with stage III tumors than those with stage II. The indirect culture of ASCs isolated from breast cancer patients and normal individuals with activated PBLs significantly reduced NKG2D+ and CD69+ NK cells (P<0.05). CONCLUSION Results of the present study suggest more evidences for the immunosuppression of ASCs on NK cells, providing conditions in favor of tumor immune evasion.

Abstract
BACKGROUND Adipose derived stem cells (ASCs) provoke the accumulation and expansion of regulatory T cells, leading to the modulation of immune responses in tumor microenvironment. OBJECTIVE To assess the effect of tumoral ASCs on the trend of regulatory T cells differentiation. METHODS Peripheral blood naïve CD4+ T cells were co-cultured with ASCs derived from breast cancer or normal breast tissues. In separate cultures peripheral blood naïve CD4+ T cells were exposed to the culture supernatants of ASCs. RESULTS Generation of CD4+CD25+Foxp3+ and CD4+CD25-Foxp3+ Treg subsets was observed after coculture of naïve CD4+ T cell with either ASCs or the related supernatant. The percentage of CD4+CD25+Foxp3+ cells increased after exposing naïve CD4+ T cells to both ASCs and their supernatants while augmentation of CD4+CD25-Foxp3+ subset mostly depended on the presence of ASCs. Similarly, upregulation of FoxP3 molecule was more significant in condition of cell to cell contact. IL-4 and IL-10 were up-regulated in the cocultured naïve CD4+ T cells after exposure to ASCs/supernatant while IFN-γ was down-regulated in the presence of ASCs. CONCLUSION ASC may act as one of the major players in tumor site with immunomodulatory effects, which may mostly be carried out through direct cell-cell interaction.

Abstract
BACKGROUND We already showed the superiority of imputation of missing data (via Multivariable Imputation via Chained Equations (MICE) method) over exclusion of them; however, the methodology of MICE is complicated. Furthermore, easier imputation methods are available. The aim of this study was to compare them in terms of model composition and performance. METHODS Three hundreds and ten breast cancer patients were recruited. Four approaches were applied to impute missing data. First we adopted an ad hoc method in which missing data for each variable was replaced by the median of observed values. Then 3 likelihood-based approaches were used. In the regression imputation, a regression model compared the variable with missing data to the rest of the variables. The regression equation was used to fill the missing data. The Expectation Maximum (E-M) algorithm was implemented in which missing data and regression parameters were estimated iteratively until convergence of regression parameters. Finally, the MICE method was applied. Models developed were compared in terms of variables significantly contributed to the multifactorial analysis, sensitivity and specificity. RESULTS All candidate variables significantly contributed to the MICE model. However, grade of disease lost its effect in other three models. The MICE model showed the best performance followed by E-M model. CONCLUSION Among imputation methods, final models were not the same, in terms of composition and perform-ance. Therefore, modern imputation methods are recommended to recover the information.

Abstract
BACKGROUND Although breast cancer in men is uncommon, its incidence rate has an increasing trend. Due to its low incidence, there are few studies in this subject and limited information is available. The purpose of this study was to investigate clinicopathological characteristics and survival of male breast cancer (MBC) in Fars Province, south of Iran. METHODS The data for this study were obtained from the population based cancer registry of Vice-Chancellor for Health Affairs of Shiraz University of Medical Sciences and Shiraz hospitals between January 1, 1989 and January 1, 2008, including 64 patients with MBC. Demographic, clinical and pathological aspects were investigated. The Kaplan-Meier method was used for the determination of survival rate and Log Rank test for the comparison. The Cox proportional hazards model was used for the multiple analysis. RESULTS The patients' mean age at the time of diagnosis was 60.3 years (SD=12.7). The most frequent age group (26.6%) was 51-60 years. The most common symptom (96.8%) was a palpable mass. The majority of patients (44.4%) had a symptom duration of less than or equal to 6 months. 56.3% of the patients had a tumor size of 2-4.9 cm. Forty six percent of the cases had axillary lymph node involvement. The median survival time was 10.0 years [95% confidence interval (CI): 6.0-14.0]. The 5 year overall survival rate was 66.0% (95% CI=51.0-81.0%). The median survival time of patients with axillary lymph node involvement was 8.2 years (95% CI=6.7-9.6) and for the cases without involvement was 12.0 years (95% CI=8.4-15.2). In addition to axillary lymph node involvement, positive family history in contrast to negative family history and left tumors in compari-son with right tumors were poorer prognostic factors in univariate analysis respectively (p=0.006, p=0.031). In multiple analysis, axillary lymph node involvement was an independent predictor of poorer survival (Hazard ratio=1.6, 95% CI=1.1-6.4, p=0.030) and the other variables did not have a significant effect. CONCLUSION The mean age of MBC in this series is lower than that in western countries. It is compatible to the mean age of female breast cancer which is approximately one decade less than that in developed countries. The survival rate of MBC is relatively lower than that in western countries. Axillary lymph node involvement is an important prognostic factor in the survival of MBC. Multicenter population based studies with greater number of patients are required for better estimation of different aspects of MBC in Iran.

Abstract
Interleukin-18 [IL-18] gene promoter polymorphism is reported to be a genetic risk factor for several types of cancer. The aims of this investigation were to evaluate and compare the frequencies of IL-18 gene promoter polymorphisms at positions -137 [G/C] and -607 [C/A] in breast cancer patients and healthy controls as well as to study the contribution of these data with clinicopathological parameters at diagnosis. The studied populations comprised 250 cases with breast carcinoma and 206 healthy subjects. IL-18 gene promoter polymorphisms at positions -137 and -607 were amplified in patient and control groups using allele specific polymerase chain reaction [AS-PCR]. The frequencies of GG, GC and CC genotypes of -137 SNP were 141 [56.4%], 96 [38.4%] and 13 [5.2%] in patients vs. 110 [53.4%], 72 [34.9%] and 24 [11.7%] in controls, respectively. A significant decrease of the CC genotype was observed in patients [p = 0.04]. The frequency of the CC genotype at position -137 was also significantly higher in patients with metastasis than non-metastatic patients [21.4% vs. 4.3%] [p = 0.02]. There was no significant association between genotype frequencies at position -607 with breast cancer or its clinicopathological parameters at diagnosis. Moreover, allelic frequencies at these positions did not contribute to breast cancer incidence. The distribution of IL-18 gene haplotypes and genotype combinations were not significantly different between patients and normal control individuals. This is the first report investigating the contribution of IL-18 gene promoter polymorphisms to breast cancer. These results suggest contrast effects of IL-18 gene in cancer induction and progression. Key words: Breast cancer, IL-18, polymorphism.

Abstract
OBJECTIVE To study fine needle aspiration (FNA) cytological findings of splenic lesions and assess the role of FNA in the diagnosis of splenomegaly or splenic tumours. METHODS This study consisted of 48 cases, 25 males and 23 females. The ages ranged between 3 and 71 years. Most of these cases were aspirated under ultrasonographic guidance and a small number were also aspirated directly by using a 22- to 23-gauge needles. The smears were stained with Wright-Giemsa and Papanicolaou methods. Special stains were used whenever necessary. RESULTS In this study 14 cases were diagnosed as lymphoma-leukaemia, 7 cases as tuberculosis, 12 cases as kala-azar, 2 cases as hydatid cyst, 3 cases as storage diseases, 3 cases as simple cyst, 2 cases as myeloproliferative disorders, 2 cases as malignant tumours and 3 cases as hamartomas (these were wrongly diagnosed as malignant tumours). CONCLUSION Splenic aspiration is a safe procedure and is very useful in the diagnosis of parasitic and infectious diseases, especially in endemic countries like Iran.

Abstract
CTLA4 is a coinhibitory molecule expressed mainly on activated T lymphocytes. To test the putative involvement of CTLA-4 in inhibitory state of immunity to breast cancer, we genotyped 283 patients and 245 healthy control subjects for -1722 T/C, -1661 A/G, and -318 C/T single nucleotide polymorphisms in the promoter region of the CTLA4 gene. There were no significant differences in genotype, allele, or haplotype frequencies in all three loci between patients and healthy controls. Moreover, the incidence of the most frequent haplotype combination (TAC/TAC, T -1722, A -1661, C -318) was only slightly higher among healthy controls than patients (68.4 vs. 64.8%, P = 0.2). This haplotype combination was associated with lower stages of the disease (P = 0.0007), however, and higher estrogen receptor (ER) expression in patients (P = 0.006). Association with tumor prognostic or predictive factors was also observed with certain genotypes: the -1661 AA genotype was associated with lesser lymph node (LN) involvement (P = 0.017) and higher ER expression (P = 0.004), and the -318 CC genotype with lesser LN involvement (P = 0.007). These results suggest that CTLA4 promoter variants participate in the progression of breast cancer rather than in its initial development.

Abstract
The association of the polymorphism in the genes of TNF-alpha, TNF-beta and IFN-gamma with breast cancer was investigated in the present study. There were no differences in the TNF-alpha and TNF-beta alleles and genotypes frequencies between breast cancer patients (n=223) and control subjects (n=267). The correlations between TNFA or TNFB alleles or genotypes and clinicopathological indices were also insignificant. However, the frequency of IFN-gamma+874 T/T genotype was significantly higher in breast cancer patients compared to those of controls (P<0.002; OR=2.03, 95% CI=1.28-3.2) which indicates that Iranian women carrying the IFN-gamma+874 T/T genotype may be exposed to an increased risk of breast cancer development.

Abstract
The earlier reports on the association between the Ile to Val polymorphism at codon 655 of HER-2 and susceptibility to breast cancer has not been found to hold true for all ethnic populations. Two hundred and four cases and 138 controls were collected to investigate the association of HER-2 Ile655Val polymorphism with the risk of breast cancer development and progression in Iranian population. This association was not found to be significant in the present study (OR = 1.16, 95% CI: 0.67-2.03). The association between HER-2 genotypes frequency and clinicopathological data was also insignificant, suggesting that the HER-2 polymorphism at codon 655 is unlikely to be a susceptibility locus in Iranian patients with breast cancer.

Abstract
INTRODUCTION In total parenteral nutrition (TPN) solution, adsorbance of insulin to polyvinylchloride (PVC) surfaces of fluid containers and infusion-sets, decrease the amount of insulin that reaches the patients. OBJECTIVE To clarify the biding sites of insulin and to propose a solution to overcome this problem. METHODS AND MATERIALS To each of four 1000ml. PVC bottles of 5 percent dextrose solution, 300 microunit of insulin per each milliliter of dextrose solution were added. Each bottle was then connected to an infusion-set and the system made to run at an infusion rate of 100ml. per hour. One milliliter samples were then collected from both the PVC bottles and infusion-sets-terminal, separately, immediately at the starting point (time zero) and 15, 30, 45 and 60 minutes thereafter. The concentrations of insulin were checked using insulin kits. RESULTS At the starting point (time zero) the mean of insulin concentrations among four PVC bottles was 213.79 microunit per each milliliter of 5 percent dextrose solution. No significant fluctuation was noted in the concentration of insulin in the PVC bottles through 60th minute period. However the concentration of insulin at infusion-set- terminal decreased significantly at the end of the same hour (p. value = 0.004). CONCLUSION Our results demonstrate that the adsorbance of insulin takes place at the surfaces of infusion sets. It follows therefore that increase in the primary dosage of insulin added to PVC infusion solutions and the selection of a suitable infusion set (polyethylene) seem to be beneficial for overcoming this problem.

Abstract
A breast cancer screening programme was evaluated for approximately 10,000 women aged 35 years and older. There were 67 cases of breast cancer. Highest rates of attendance were seen among younger women (35-44 years) and middle socioeconomic groups. Lowest rates were among those aged over 65 years and low socioeconomic groups. The rate of detection by self-examination was similar to that by health personnel examination. At all stages of screening, positive findings were most common among the high socioeconomic class. Attendance decreased steadily from first to last stages of serial screening. Although mammography is the most sensitive method of detection, because of its high cost we suggest establishing breast self-examination education programmes and encouraging women to self-examine.

Abstract
BACKGROUND Foreign body material (gauze sponges) presented as cystic abdominal masses and were confused with malignant tumors. CASES Two females and one male presented with abdominal masses. They had undergone laparotomy 5-12 years earlier. Clinically the masses were diagnosed as benign or malignant cystic lesions. Fine needle aspiration revealed necrotic material, hemosiderin-laden macrophages, foreign body giant cells, cholesterol crystals and many fragments of birefringent material. The possibility of malignancy was ruled out. Cut sections of the excised cystic lesions revealed gauze sponges surrounded by a thick, fibrotic wall. CONCLUSION This report underscores the usefulness of fine needle aspiration in ruling out malignancy.

Abstract
OBJECTIVE To study the prevalence and significance of bull's eye (target) inclusions in neoplastic cells in malignant serous effusions. STUDY DESIGN We reviewed malignant pleural, peritoneal and pericardial effusions from 289 patients who had proven cancer at known primary sites. The ages of the patients ranged from 5 to 72 years; 166 were male and 123 female. RESULTS Bull's eye inclusions are an uncommon finding and appeared in only 13 cases of metastatic adenocarcinoma of the breast, stomach, colon, lung, ovary, pancreas and urinary bladder. They were positively stained with periodic acid-Schiff stain with diastase. The inclusions were not seen in cells of nonadenocarcinomatous neoplasms, such as squamous cell carcinoma, oat cell (small cell) carcinoma, neuroblastoma, lymphoma and germ cell tumors. CONCLUSION Bull's eye inclusions are found in about 5% of malignant serous effusions containing cells of metastatic adenocarcinoma. The primary site of an adenocarcinoma cannot be deduced on the basis of the presence of inclusions.

Abstract
Data on the reproductive behaviour of women in Shiraz are presented. A total of 9934 randomly selected women aged > or = 35 years of all socioeconomic levels were interviewed. The mean age at menarche +/- standard deviation was 13.96 +/- 1.23 years, mean age at first marriage was 17.10 +/- 4.24 years and mean age at first pregnancy was 19.50 +/- 3.90 years. The mean number of children was 4.56 +/- 1.70 children, although for illiterate women it was 6.76 +/- 1.76 children and for high-school- or university-educated women it was 3.36 +/- 1.70 children. The mean age at menopause was 47.80 +/- 3.78 years.

Abstract
OBJECTIVE To study the cytologic findings of papillary breast carcinoma by fine needle aspiration. STUDY DESIGN The study group consisted of fine needle aspiration (FNA) specimens of breast tumors from nine patients performed during the period 1988-1997. Eight were female, and one was male. The FNA results were compared with the final histologic diagnosis. RESULTS The tumor sizes were 4-6.5 cm. The aspirations yielded a good amount of bloody material. The smears revealed high cellularity, papillary clusters, isolated low-to-tall columnar cells, mild to moderate atypia, hemorrhagic background, foam and hemosiderin-laden macrophages, calcification, rare mitoses, palisading row of cells and bipolar cytoplasmic eosinophilic granules. The smears were diagnosed as either suspicious or suggestive of papillary carcinoma. The histologic examination revealed invasive papillary carcinoma. CONCLUSION Papillary carcinoma of the breast can be diagnosed by using a panel of cytologic findings that includes hypercellularity, papillary clusters, hemorrhagic background, palisading rows of tall columnar cells, cellular atypia and calcification. The interesting finding in this study was the presence of eosinophilic bipolar cytoplasmic granules, which has not been reported before.

Abstract
BACKGROUND Primary squamous cell carcinoma of the thyroid is a rare malignant tumor that needs to be distinguished from other neoplasms. CASES Two males aged 65 and 68 years presented with an enlarged right lobe of the thyroid. Thyroid scintigraphy revealed a cold nodule. Clinically malignancy was suspected. Fine needle aspiration (FNA) revealed numerous clusters and isolated malignant cells, dyskeratotic cells and deposits of eosinophilic granular keratin material. Subtotal thyroidectomy was performed. Histologic findings confirmed the cytologic diagnosis of squamous cell carcinoma. CONCLUSION Primary squamous cell carcinoma of the thyroid is a rare tumor. FNA findings of this tumor were not reported before. FNA study cannot help to differentiate primary from metastatic squamous cell carcinoma of the thyroid.

Abstract
OBJECTIVE To study the cytologic findings of follicular variant of papillary thyroid carcinoma (FVPTC) and to compare them with the cytologic findings on other thyroid lesions. STUDY DESIGN The study group consisted of aspirate smears from 15 cases of histologically proven FVPTC. The control group consisted of 152 cases, including adenomatous colloid goiter (70), usual papillary carcinoma (40), follicular adenoma (30), Hürthle cell neoplasm (7) and medullary carcinoma (5). RESULTS The smears of FVPTC revealed numerous colloid balls in the background, multilayered microfollicles (rosettes), numerous nuclear grooves and inclusions in the monolayer sheets of follicular cells, very rare giant cells, absence of calcification and papillary clusters. Rosettelike microfollicles and numerous colloid balls were not seen in the control group. CONCLUSION The combination of numerous colloid balls and rosettelike microfollicles was frequently seen in FVPTC. This combination was not observed in the control group.

Abstract
OBJECTIVE To determine the role of fine needle aspiration cytology in the diagnosis of extramedullary plasmacytoma. STUDY DESIGN The study group consisted of 13 patients with palpable masses at various sites. The tumors were aspirated for cytologic study. RESULTS The smears revealed groups of mature and immature plasma cells at various stages of maturation. Mature plasma cells showed an eccentric nucleus and abundant, deep, basophilic cytoplasm with a paranuclear halo. Plasmablasts (immature plasma cells) showed a prominent, eccentric nucleus with single, large nucleolus and abundant, deep, basophilic cytoplasm with no paranuclear halo. Binucleate and multinucleate forms were also seen quite often. The tumors were excised, and the histologic sections confirmed the cytologic diagnosis. All the patients received radiotherapy. One patient (18 years old) developed recurrence and died due to extensive infiltration into the maxilla and mandible. Two patients (57 and 62 years) developed multiple myeloma one to two years after the excision of tumors, and both died two to three months later. The remaining 10 patients were alive and well at this writing. CONCLUSION The smears from all 13 patients were diagnosed as extramedullary plasmacytomas by fine needle aspiration cytology.
