BACKGROUND
Of the many prognostic factors for breast cancer, the relationship between an infiltration of inflammatory cells and the prognosis is debatable. Of the chemokines affecting cancer's inflammatory reactions, chemokine (C-X-C motif) ligand 16 (CXCL16) has attracted attention for its prognostic value in many cancers, including colorectal cancer and renal cell carcinoma. But the situation for breast carcinoma is unknown. The aim of this study was to examine the relationship between the prognostic factors and the CXCL16 expression in patients with breast carcinoma.
METHODS
The patients (n=106) diagnosed with invasive ductal cancer of the breast were enrolled. We reviewed the clinicopathological factors of these patients, hematoxylin and eosin stains were prepared and estrogen receptor (ER), human epidermal growth factor receptor 2 (HER2/neu) and CXCL16 immunostaining was performed.
RESULTS
The ER expression was significantly correlated with age and inflammation. A CXCL16 expression was noted in 81.1% of the cases. No association was evident between a CXCL16 expression and any other parameter, including the survival rate. Multivariate analysis did not implicate ER, HER2/neu or CXCL16 as an independent prognostic factor, but the tumor size was independent predictive factor for the patient outcome.
CONCLUSIONS
An inflammatory reaction mediated by CXCL16 is not associated with the prognosis of breast cancer or any clinicopathological factors.

Abstract PDF: Bladder reconstruction using bowel segments, especially the ileum, has become a realistic option for urinary diversion. There is only one prior case of squamous cell carcinoma of the ileal neobladder that has been reported in the clinical literature. Here we report a patient with a spectrum of squamous cell lesions, including squamous cell carcinoma, sarcomatoid carcinoma, squamous papilloma and squamous metaplasia that developed in the ileal neobladder. A 46-year-old woman underwent a hysterectomy, cystectomy and ileocystoplasty for tuberculosis 25 years previously complained of urinary frequency and gross hematuria for one week. A pelvic CT revealed a 6.3 cm mass in the neobladder. The histopathological examination showed an 11x8 cm polypoid fragile mass with a microscopically well-differentiated squamous cell carcinoma, squamous papilloma and non-tumor squamous metaplasia.

Abstract PDF: BACKGROUND
Slug is a member of the Snail family of transcription factors, and it plays a crucial role in the regulation of the epithelial-mesenchymal transition by suppression of several epithelial proteins and adhesion molecules, including E-cadherin. METHODS: The aim of the present study was to examine the significance between the expression of Slug in colorectal adenocarcinoma (CRA) specimens and the clinicopathological parameters of CRA, as determined by immunohistochemical analysis, and to determine the correlation between the Slug and E-cadherin expressions in non-neoplastic colorectal mucosa (n=45), primary CRA (n= 109) and metastatic CRA (n=17). A semiquantitative scoring system was applied based on the intensity and extent of the positive immunohistochemical staining. RESULTS: The expressions of Slug and E-cadherin were associated with the depth of tumor invasion (pT) (p=0.019, p=0.001, respectively), and these expressions showed a significant inverse correlation (p<0.001) each other. CONCLUSIONS: Our results demonstrated a positive role for Slug in the development of CRA, and Slug is a mediator of tumor invasion in CRA. In addition, an up-regulated Slug expression is significantly correlated with the loss of an E-cadherin expression, which suggests that Slug may play some role in the epithelial-mesenchymal transition (EMT) by down-regulating the E-cadherin expression.

Abstract PDF: Gastric yolk sac tumors are extremely rare with only a few cases reported in the literature. Here, we present the case of a 50-year-old man with an adenocarcinoma and a yolk sac tumor of the stomach, without metastasis to the lymph nodes. The tumor was an early gastric carcinoma confined to the submucosa. Twelve months post-operation the patient was alive with no complications. The yolk sac tumor showed positive labeling for alpha-fetoprotein (AFP), alpha1-antitrypsin (alpha1-AT), cytokeratin (CK) and carcinoembryonic antigen (CEA), but was negative for human chorionic gonadotrophin (hCG), placental alkaline phosphatase (PLAP), epithelial membrane antigen (EMA) and p53. The adenocarcinoma was positive for alpha1-AT, CK, EMA, and CEA, but was negative for AFP, hCG, PLAP, and p53. These findings suggest that the yolk sac tumor and the adenocarcinoma components are closely related and may represent distinct phenotypes that arise from a common mucosal epithelial cell.
