This study aimed to evaluate the morphometric measurements in cases with papillary thyroid carcinoma, and determine a cut-off value to support diagnosis. Fifty cases with a diagnosis of papillary thyroid carcinoma (PTC) were included in the study with their Galectine-3, CK-19 and HBME-1 immunohistochemical staining results. Demographic and clinical data gathered from pathology reports, which included demographic information such as patients' sex, age, macroscopic tumor size, number of tumor focuses; prognostic parameters such as lenfovascular invasion, perineural invasion, thyroid capsule invasion; and results of immunohistochemical CK- 19, Galectin-3 and HBME-1 staining...

BACKGROUND: In early-stage esophageal adenocarcinoma (EAC), esophagectomy improves staging but also increases mortality compared with endoscopic resection. Our objective was to quantify esophagectomy mortality and lymph node metastasis (LNM) risk in early-stage EAC to improve surgical treatment allocation. METHODS: We identified National Cancer Database (2004-2014) patients with nonmetastatic, Tis, T1a, or T1b EAC who had primary surgical resection and microscopic examination of at least 15 lymph nodes...

BACKGROUND: The worldwide incidence of neuroendocrine tumors (NETs) has increased remarkably, with the hindgut being the second most common site for such tumors. However, the mechanisms underlying progression and metastasis of hindgut NETs are unclear. A retrospective study was conducted to elucidate these mechanisms. METHODS: Clinicopathological data of cases of hindgut NET between April 1996 and September 2015 were analyzed, retrospectively. Patients with neuroendocrine carcinoma were excluded...

The aim was to investigate MAGE-A4 and MAGE-A1 protein expression in high-grade endometrial cancer and determine its correlation with histologic subtype, FIGO stage, presence of vascular invasion, disease free, and overall survival. Immunohistochemical staining was performed by using 77B (MAGE-A1) and 57B (MAGE-A4) monoclonal antibodies on paraffin-embedded sections from high-grade endometrial cancers diagnosed in University Hospital Split between 1998 and 2011 (n=77). Median follow-up time for survivors was 48 mo...

INTRODUCTION: Diagnosis of colorectal cancer (CRC) based on clinical symptoms is usually established in its advanced stages. One strategy for reducing mortality is the early detection and removal of preneoplastic and initial neoplastic lesions, even before the first symptoms appear, by means of population-based screening campaigns. The aim of the present study is to determine whether CRC diagnosed via a screening campaign has more favourable histopathological prognostic factors than when diagnosed in the symptomatic phase...

BACKGROUND: In patients treated for early-stage squamous cell vulvar carcinoma local recurrence is reported in up to 40% after ten years. Knowledge on prognostic factors related to local recurrences should be helpful to select high risk patients and/or to develop strategies to prevent local recurrences. OBJECTIVE: This systematic review aims to evaluate the current knowledge on the incidence of local recurrences in vulvar carcinoma related to clinicopathologic and cell biologic variables...

BACKGROUND: TP53 mutations are rarely identified in low grade endometrioid carcinoma of the endometrium, and their pathogenic significance in such tumors is evidenced by the fact that TP53 aberrations have been associated with reduced recurrence-free survival in this subset of tumors. However, TP53 aberrations may not always represent a driving molecular event in a given endometrial cancer with a mutation. In this case study, the immunophenotype of a distinctive low grade endometrioid adenocarcinoma with an unusual pattern of lymph node metastases is used to explore the possible roles for underlying TP53-related molecular events in its pathogenesis...

HOX family members encode transcription factors crucial for embryogenesis and may be associated with carcinogenesis. Here, we evaluated the expression of 39 HOX genes in cervical cancer by using clinicopathological information and gene expression data of 308 patients from The Cancer Genome Atlas (TCGA) database. Correlations between mRNA expression of HOX family members and clinicopathological variables were explored. Seventy-three (23.7%) patients died during the follow-up period (median, 22.0 months). Overall mortality was significantly associated with advanced FIGO stage, lymph node metastasis, lymphovascular invasion, and increased HOXA1, HOXA5, HOXA6, and HOXC11 mRNA expression...

The purpose of our study was to evaluate the association between metabolic parameters on FDG PET/CT and axillary lymph node metastasis (ALNM) in patients with invasive breast cancer.From January 2012 to December 2012, we analyzed 173 patients with invasive ductal carcinoma (IDC) who underwent both initial breast magnetic resonance imaging (MRI) and F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) examinations. All metabolic parameters were measured from the tumor volume segmented by a gradient-based method...

The purpose of this study was to assess the consistency of maximum uptake values (SUVmax) changes and pCR in hormone-positive locally advanced breast cancer (LABC). METHODS: Ninety hormone-positive LABC patients treated at Marmara University Medical Oncology Clinic, Istanbul, Turkey, between 2009 and 2015 were retrospectively studied...

PURPOSE: This study aimed at exploring the role of Skp2, p27 and Cks1 expression as prognostic factors for colorectal cancer (CRC) patients, and to identify a correlation between their expression and the cell proliferation marker Ki67. METHODS: We conducted a retrospective study on 130 patients with CRC treated with surgery and adjuvant treatment at the Oncology Institute Cluj-Napoca between 2006- 2010. The Skp2, p27, Cks1 and Ki67 immunoexpression was grouped from 1 to 4, according to percents of tumor cells with nuclear reactivity...

Furthermore, to evaluate the value of LVI and VH at TUR for predicting non-organ confined (NOC) disease, lymph node metastasis, and survival outcomes. PATIENTS AND METHODS: Two hundred and sixty-eight patients who underwent TUR and subsequent RC were reviewed. Logistic regression analyses were performed to evaluate the association of LVI and VH with NOC and lymph node metastasis at RC...

BACKGROUND: Literature data reported a higher frequency of breast cancer in young women (BCYW) in developing countries. BCYW is associated with delayed diagnosis, aggressive biology and poor prognosis. However, our knowledge of biological profile, treatment received and outcome of young patients is still limited in Morocco. We propose to analyze clinicopathologic, therapeutic and prognostic features of BCYW among a series of patients native and/or inhabitant of North of Morocco. METHODS: We carried out a retro-prospective study of 331 infiltrating breast cancer cases registered between January 2010 and December 2015...

BACKGROUND: A subset of patients with rectal cancer who undergo neoadjuvant chemoradiation therapy will develop a complete pathologic tumor response. Complete nodal response is not universal in these patients and is difficult to assess clinically. Quantifying the risk of nodal disease would allow for targeted therapy with either radical resection or "watchful waiting." OBJECTIVE: This study aimed to identify risk factors for residual nodal disease in ypT0 rectal adenocarcinoma...
