Abstract
Thyroid carcinomas represent a challenging problem from the prognostic standpoint. Despite an overall good prognosis of the most frequent endocrine malignancy, 10-15 % of papillary thyroid carcinomas (PTCs) turn refractory to radioactive iodine therapy. The increased incidence of thyroid cancer has led to the search for solid prognostic biomarkers that predict the behaviour of these tumours. Clinical and histopathological prognostic factors remain the only safe elements to be used for diagnosis and prognosis of patients with thyroid tumours. Despite the huge amount of genetic information of thyroid tumours, very few new markers revealed diagnostic or prognostic value per se. BRAF mutation can have some value if associated to other clinico-pathological parameters, or in the particular setting of iodine refractory tumours. Others can prove interesting in the future as predictive biomarkers of therapeutic response, but more studies are needed to confirm these potential biomarkers.

Abstract
We try to identify the relationship between immunohistochemical marker expression and lymph node involvement in a cohort of 282 patients followed for 5 years after curative resection for NSCLC. In 189 patients (67%), lymph nodes were unaffected while 93 patients (33%) showed nodal involvement. The expression of 15 molecular markers was determined from each patient by tissue-array immunohistochemistry. Univariate analysis indicated significantly higher expression of E-cadherin, γ-catenin, p27, and p53 in patients with lymph node involvement. In those with unaffected nodes, p16 and Rb were expressed. E-cadherin expression was related to a 50% mortality reduction in patients with node involvement (hazard ratio (HR) 0.5; p = 0.017). c-erbB-2 expression was correlated with a 3.4-fold increase in mortality compared to patients without expression of this marker in subjects without node involvement (HR 3.41; p = 0.017). Multivariate analysis identified c-erbB-2 (HR 2.22; p = 0.089) and p27 (HR 1.44; p = 0.019) as prognostics of mortality while Rb (HR 0.74) indicated a good prognosis. The expression of proteins encoded by oncogenes and tumor suppressor genes was different according to lymph node involvement. The increased mortality related to c-erbB-2 expression in patients with unaffected lymph nodes would suggests a need for adjuvant treatment.

Abstract
AIM: To investigate the changing pattern of α-catenin expression and its relationship to clinical and pathological features of colorectal cancer (CRC) patients.
METHODS: Archival tumor samples were analyzed using immunohistochemistry (IHC) for α-catenin in 91 patients with advanced CRC.
RESULTS: The values of α-catenin membrane index (MI) and cytoplasmic index (CI) were significantly related to the depth of tumor invasion (P = 0.027, P = 0.020, respectively), high indices being associated with increased depth of the primary tumor invasion (T3 and T4). Similarly, patients with high α-catenin expression had a significantly increased risk of lymph node metastasis (32/39 vs 37/52 for MI and 37/45 vs 32/46 for CI) (P = 0.001, P = 0.0001, respectively, for LNN status). An altered expression (i.e., cytoplasmic pattern) was also related (P = 0.047) to the response to chemotherapy; patients with low CI were more responsive (CR: 7/46) than patients with high CI values (CR: 0/45). There was a marginal effect on survival in patients time with metastases (SWM) (P = 0.087); patients with low CI showing slightly longer SWM, but no such effect on disease free survival (DFS) or disease specific survival (DSS). As to co-expression with another member of the adhesion complex (β-catenin), high α-catenin/β-catenin MI index was of marginal significance in predicting longer DSS (P = 0.063, log-rank).
CONCLUSION: The results implicate that high α-catenin expression is intimately involved in the key regulatory mechanisms leading to invasive phenotype, lymph node metastases, and progressive disease in CRC.

Abstract
The cadherin/catenin complex, comprised of E-cadherin, beta-catenin and alpha-catenin, is essential for initiating cell-cell adhesion, establishing cellular polarity and maintaining tissue organization. Disruption or loss of the cadherin/catenin complex is common in cancer. As the primary cell-cell adhesion protein in epithelial cells, E-cadherin has long been studied in cancer progression. Similarly, additional roles for beta-catenin in the Wnt signaling pathway has led to many studies of the role of beta-catenin in cancer. Alpha-catenin, in contrast, has received less attention. However, recent data demonstrate novel functions for alpha-catenin in regulating the actin cytoskeleton and cell-cell adhesion, which when perturbed could contribute to cancer progression. In this review, we use cancer data to evaluate molecular models of alpha-catenin function, from the canonical role of alpha-catenin in cell-cell adhesion to non-canonical roles identified following conditional alpha-catenin deletion. This analysis identifies alpha-catenin as a prognostic factor in cancer progression.

Abstract
OBJECTIVE To clarify the prognostic role of E-cadherin and beta- and gamma-catenins, and their relation to CD44 in epithelial ovarian carcinoma. METHODS The expression of E-cadherin and beta- and gamma-catenins was analysed immunohistochemically in 305 primary epithelial ovarian cancers and 44 metastases, and related to CD44 expression, clinicopathological factors, and the patients' survival. RESULTS Reduced cell surface expression of E-cadherin, beta-catenin, and gamma-catenin was particularly frequent in serous and endometrioid histological types. Reduced cell surface expression of E-cadherin and beta-catenin was also associated with poor differentiation. Nuclear positivity of beta-catenin was associated with high CD44 expression, endometrioid histology, and local stage of the tumour, whereas nuclear gamma-catenin expression was associated with serous histology and poor differentiation. In the univariate analysis, preserved cell surface beta-catenin expression in the whole study material and nuclear expression of beta- and gamma-catenins in the subgroup of endometrioid ovarian cancers were predictors of better 10 year disease related survival. Preserved cell surface expression of E-cadherin and beta-catenin predicted favourable recurrence-free survival. These statistical significances were not retained in multivariate analysis. CONCLUSIONS The correlation between nuclear beta-catenin and CD44 indicates that beta-catenin may regulate the transcription of CD44 in epithelial ovarian cancer. E-cadherin-catenin complex members are associated with the prognosis of patients with epithelial ovarian cancer, but these univariate associations were not strong enough to compete for significance with the traditional clinicopathological factors.

Abstract
The study looked for an optimal set of genes differentiating between papillary thyroid cancer (PTC) and normal thyroid tissue and assessed the sources of variability in gene expression profiles. The analysis was done by oligonucleotide microarrays (GeneChip HG-U133A) in 50 tissue samples taken intraoperatively from 33 patients (23 PTC patients and 10 patients with other thyroid disease). In the initial group of 16 PTC and 16 normal samples, we assessed the sources of variability in the gene expression profile by singular value decomposition which specified three major patterns of variability. The first and the most distinct mode grouped transcripts differentiating between tumor and normal tissues. Two consecutive modes contained a large proportion of immunity-related genes. To generate a multigene classifier for tumor-normal difference, we used support vector machines-based technique (recursive feature replacement). It included the following 19 genes: DPP4, GJB3, ST14, SERPINA1, LRP4, MET, EVA1, SPUVE, LGALS3, HBB, MKRN2, MRC2, IGSF1, KIAA0830, RXRG, P4HA2, CDH3, IL13RA1, and MTMR4, and correctly discriminated 17 of 18 additional PTC/normal thyroid samples and all 16 samples published in a previous microarray study. Selected novel genes (LRP4, EVA1, TMPRSS4, QPCT, and SLC34A2) were confirmed by Q-PCR. Our results prove that the gene expression signal of PTC is easily detectable even when cancer cells do not prevail over tumor stroma. We indicate and separate the confounding variability related to the immune response. Finally, we propose a potent molecular classifier able to discriminate between PTC and nonmalignant thyroid in more than 90% of investigated samples.

Abstract
The morphologic distinction of benign and malignant thyroid follicular lesions can sometimes be challenging, therefore an immunohistochemical marker to aid in this distinction would be useful. beta-Catenin is one such potential marker. It is part of a membrane-bound cell growth-signaling complex that plays a role in cell adhesion, as well as in promotion of growth through activation of the Wnt signaling pathway. Oncogenic signaling occurs when beta-catenin is released, accumulates in the cytoplasm, translocates into the nucleus, and promotes transcription of genes including bcl-1 (cyclin D1) and c-myc that induce cell proliferation. Paraffin blocks from 133 thyroidectomy specimens were stained with monoclonal antibodies reactive with beta-catenin and cyclin D1. These included 53 cases of papillary thyroid carcinoma (PTC), 46 cases of follicular variant of papillary carcinoma (FVPC), 10 cases of follicular carcinoma (FC), and 24 cases of follicular adenoma (FA). Tissue from six normal thyroid specimens served as a control. The malignant lesions (PTC, FC, and FVPC) expressed strong cytoplasmic/nuclear staining and minimal residual membranous staining in 87%, 80%, and 71% of cases, respectively. In contrast, all normal thyroid tissue and 79% of FAs showed strong membranous reactivity with very minimal cytoplasmic staining. Interestingly, in 83% of PTC cases and 20% FVPCs, the intranuclear inclusions were distinctly beta-catenin positive. Cyclin D1 over expression correlated with cytoplasmic relocalization of beta-catenin in almost all cases, and no evidence of cyclin D1 gene amplification was observed. beta-Catenin can be of a diagnostic utility for thyroid lesions, because it highlights intranuclear inclusions in PTC, and shifts from a membranous localization to a cytoplasmic localization in malignant lesions. We speculate that the localization of beta-catenin in intranuclear inclusions may reflect a cytoskeletal remodeling activity of beta-catenin that is functionally significant for the PTC pathway.

Abstract
E-cadherin and catenins play a major role in neoplastic cell behavior as a suppressor of invasion and/or metastasis. The aim of this study was to determine E-cadherin, alpha-catenin and beta-catenin expressions in papillary thyroid carcinoma (PTC) and to correlate the results of expression to initial clinicopathological parameters and clinical outcome. Forty-one cases (mean age 37.3 +/- 11.2 yr) with PTC were studied. Patients were followed-up with a mean period of 47.6 +/- 27.0 months. A retrospective immunohistochemical analysis of E-cadherin, alpha-catenin and beta-catenin was performed on paraffin-embedded tissue sections. Tissues from ten patients with benign goiter were used as controls. E-cadherin, alpha- and beta-catenin immunoreactivities were found in 80% (33/41), 76% (31/41) and 97% (40/41) of patients respectively. No correlation was found between E-cadherin, alpha- and beta-catenin immunoreactivities and sex, local invasion or lymphatic spread at the time of initial examination. Distant metastases and/or local recurrences developed in 6 patients during follow-up. Recurrences/metastases developed both E-cadherin, alpha- and beta-catenin positive and negative primary tumors. Disease-free survival curves according to Kaplan-Meier analysis and log-rank test did not show any significant differences between E-cadherin, alpha- and beta-catenin positive and negative patients. According to our findings, E-cadherin, alpha- and beta-catenin expressions may not add any valuable information to the follow-up in a subgroup of PTC patients with a relatively benign course.
