BACKGROUND: Papillary thyroid microcarcinomas (PTMCs) often demonstrate lateral lymph node (LN) metastasis. The purpose of this study was to assess whether the size of primary tumor should be considered in deciding lateral neck dissection extent. METHODS: We conducted a retrospective comparison of patients with PTMC and papillary thyroid carcinoma (PTC) larger than 1 cm who received lateral LN dissection from 2009 to 2015. RESULTS: PTMC group had more frequent metachronous metastasis, multifocality, less involvement of lower third thyroid, lower metastatic central LN counts and ratio, and lower metastatic total LN ratio...

OBJECTIVE: To elucidate the biological functions of long non-coding RNA (lncRNA) SNHG7 in breast cancer (BC), and its underlying mechanism in the occurrence and progression of BC. PATIENTS AND METHODS: The expression of SNHG7 in 72 pairs of BC tissues and paracancerous tissues was detected by quantitative Real-time polymerase chain reaction (qRT-PCR). Correlation between SNHG7 expressions with pathological indicators of BC patients was analyzed. Similarly, SNHG7 expression in BC cell lines was determined by qRT-PCR as well...

OBJECTIVE: Increasing evidence has revealed that microRNAs (miRNAs) act as key players in the regulation of tumor growth and metastasis in epithelial ovarian cancer (EOC). However, the clinical role and functional effects of miR-1294 in EOC remain unknown. PATIENTS AND METHODS: We examined the expression of miR-1294 in 69 cases of EOC tissues and cell lines by quantitative Real-time polymerase chain reaction (qRT-PCR).

miR-95 has been revealed to be aberrantly expressed in multiple types of cancer and to regulate tumor development. Moreover, miR-95 has been revealed to be downregulated in gastric cancer. However, the detailed function of miR-95 in gastric cancer has remained largely unknown. In the present study, we found that miR-95 was downregulated in 63 pairs of gastric cancer tissue samples and adjacent normal tissue samples, as well as gastric cancer cell lines. Additionally, the expression of miR-95 was associated with tumor size, tumor‑node‑metastasis (TNM) stage and lymph node metastasis...

Advances in endoscopic-assisted neck surgery have allowed surgeons to conceal the scars via various approaches. However, studies comparing the approaches are still rare. The aim of this study was to comparatively analyze the feasibility and oncological outcomes of the retroauricular approach (RA) and the small transcervical approach (STC) for endoscopic-assisted selective neck dissection (EASND). Five fresh cadavers were recruited. EASND was performed via RA on one side and via STC on the contralateral side of each of the cadavers...

INTRODUCTION: Although the first laparoscopic gastrectomy was performed in 1991, there was a long delay until it was incorporated into the regular practice of western surgeons. In Brazil, there are only few case series reported and data on its safety and efficacy along with mid- and long-term results are desired. OBJECTIVE: Present the mid-term results of laparoscopic gastrectomy with curative intent in the treatment of gastric adenocarcinoma and review the current evidence on the therapy of this neoplasia with the laparoscopic access...

Positron emission tomography (PET) with prostate-specific membrane antigen (PSMA) has found widespread use for the diagnosis of biochemical recurrence of prostate cancer (PCa). Unfortunately, PET/CT is not as widely available; thus a PSMA-targeting compound for scintigraphy is of special interest. The aim of this study was to compare 99m Tc-EDDA/HYNIC-iPSMA and 68 Ga-PSMA-11 PET/CT qualitatively and semi-quantitatively. Twenty-three patients with metastatic PCa were underwent 99m Tc-EDDA/HYNIC-iPSMA SPECT/CT followed by 68 Ga-PSMA-11 PET/CT...

Objective: To validate the necessity of increasing the examined lymph node (ELN) count for enhancing the accuracy of prognostic evaluation of gastric cancer (GC) patients after curative gastrectomy in multiple medical centers of China. Methods: The clinicopathological data of 7,620 patients who underwent the curative resection for GC between 2001 and 2011 were included to demonstrate whether the ELN count is indispensable for enhancing the accuracy of prognostic evaluation of GC patients after surgery...

Postoperative hepatocellular carcinoma (HCC) recurrence and metastasis throw great threaten to its overall survival (OS). This paper focus on exploring the prognostic significance of NANOG and OCT4 expression in HCC recurrence and OS after liver transplantation. Eighty-six patients who meet University of California San Francisco (UCSF) criteria and underwent liver transplantation in Tianjin First Central Hospital between August 2010 and August 2013 were included. Expression of NANOG and OCT4 was determined by immunohistochemistry...

Background: Accurate predictors of locally advanced and recurrence disease in patients with gastrointestinal cancer are currently lacking. Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have emerged as possible markers for predicting recurrence in these patients. In this study, we sought to evaluate the utility of NLR and PLR in predicting the presence of regional nodal disease, metastasis and systemic recurrence in patients with gastrointestinal malignancies...

Beyond its anti-fibrinolytic mechanism, tranexamic acid has been suggested to have anti-inflammatory properties which may contribute to the survival benefit it provides to trauma patients. The objective of this study was to assess possible immunomodulatory effects of tranexamic acid as well as potential amelioration of end-organ injury in a rodent hemorrhagic shock model. Controlled hemorrhagic shock was induced in adult Sprague Dawley rats to a mean arterial pressure of 30 mmHg. Groups of 10 rats were administered intravenous tranexamic acid (300mg/kg) or vehicle control (normal saline) intravenously 15 minutes after the induction of shock...

BACKGROUND/AIMS: MicroRNAs (miRNAs) are a group of non-coding RNAs that play diverse roles in pancreatic carcinogenesis. In pancreatic ductal adenocarcinoma (PDAC), NF-kB is constitutively activated in most patients and is linked to a mutation in KRAS via IkB kinase complex 1 (IKK1, also known as IKKa). We investigated the link between PDAC aggressiveness and miR-1290. METHODS: We used miRCURYTM LNA Array and in situ hybridization to investigate candidate miRNAs and validated the findings with PCR...
