The aim of this study is to identify optimal patients for adjuvant radiation therapy (ART) in pT3 prostate cancer. The role of ART for patients with adverse pathologic features after radical prostatectomy (RP) has been demonstrated, but over- or under-treatment remains a significant concern. Two-hundred and five patients with pT3N0M0 who underwent robot-assisted RP without ART were analyzed. Multivariate Cox proportional regression analyses were used to identify predictors of biochemical recurrence (BCR) and clinical progression (CP)...

BACKGROUND: Extrathyroidal extension (ETE) is a poor prognostic factor in papillary thyroid carcinoma (PTC). However, the impact of the degree of ETE, especially microscopic ETE, has not been well established. The purpose of present study was to compare differences in clinicopathological characteristics and clinical outcomes according to the presence or extent of ETE. METHODS: Data from 381 patients who underwent total thyroidectomy with/without lymph node (LN) dissection for PTC between 2004 and 2010 were analyzed...

A comprehensive repertoire of human microRNAs (miRNAs) that could be involved in early melanoma invasion into the dermis remains unknown. To this end, we sequenced small RNAs (18-30 nucleotides) isolated from an annotated series of invasive melanomas (average invasive depth, 2.0 mm), common melanocytic nevi, and matched normal skin (n=28). Our previously established bioinformatics pipeline identified 765 distinct mature known miRNAs and defined a set of top 40 list that clearly segregated melanomas into thin (0...

Right-sided colon cancer (RCC) has a poorer prognosis and a higher relapse rate than left-sided colon cancer (LCC). Like cancer stem cells (CSCs), RCC cells cannot be fully eradicated and are often involved in relapse or metastasis. Because CSCs may be linked with poor outcomes, CSC markers may have prognostic value in RCC. ATP-binding cassette sub-family G member 2 (ABCG2) and OCT-4 (also known as POU5F1) are among the most useful markers for CSC identification. We therefore examined the malignant behavior of ABCG2 and OCT-4 in vitro and in vivo, and their expression was assessed in pathology tissues obtained from clinicopathologically recurrent and non-recurrent cases...

The Ferguson Operating Anoscope (FOA) is a surgical instrument, which can facilitate transanal excision of appropriate rectal tumors within 15 cm of the anal verge. Previous work showed low recurrence (4.3%) for favorable T1 tumors (no lymphovascular invasion, well/moderate differentiation, negative margins). This follow-up study evaluates outcomes in rectal cancer excised with FOA at a tertiary care center. T1 rectal cancer patients were identified in a prospectively maintained database. Tumor pathology and patient characteristics were reviewed...

BACKGROUND: Gastric carcinoma with lymphoid stroma (GCLS) is characterized by undifferentiated carcinoma mixed with prominent lymphoid infiltration. GCLS has unique clinicopathological features and a better prognosis compared to other types of gastric cancer. We analyzed the clinicopathological features of early GCLS in relation to lymph node metastasis (LNM). METHODS: We performed a retrospective analysis of 241 patients diagnosed with GCLS confined to the mucosa or the submucosa between March 1998 and December 2015...

Background: Although surgical resection with chemotherapy is considered effective for patients with advanced gastric cancer, it remains the third leading cause of cancer-related death in South Korea. Several studies have reported that mesothelial markers including mesothelin, calretinin, and Wilms tumor protein 1 (WT1) were positive in variable carcinomas, associated with prognosis, and were evaluated as potential markers for targeted therapy. The aim of this study was to assess the immunohistochemical expression of mesothelial markers (mesothelin, calretinin, and WT1) in gastric adenocarcinoma and their relations to clinocopathological features and prognosis...

Tumor budding (TB) in colorectal carcinoma (CRC) is related to epithelial-mesenchymal transition (EMT) and has been recently characterized as an indicator of poor prognosis along with lymphovascular tumor emboli (LVE), perineural invasion (PNI), and an infiltrative growth pattern. Mutations in the genes of the Ras-MAPK and PI3K pathways are associated with EMT and an aggressive CRC phenotype and have been used in patient stratification for anti-EGF receptor therapies; however, the impact of these mutations on CRC morphology and behavior remains unclear...
