The incidence of papillary thyroid microcarcinoma (PTMC) has risen rapidly in recent years, and PTMC patients with central lymph node metastasis (CLNM) usually have poor prognosis. Independent risk factors predicting CLNM in PTMC have not been well understood. The aim of our study was to identify useful clinicopathological risk factors predicting CLNM in PTMC patients. This was a retrospective study of 917 patients with PTMC treated with surgery from January 2014 to December 2015 in our hospital. The relationship between clinicopathological factors and CLNM was analyzed to identify those factors predicting CLNM in PTMC...

Importance: Standard treatment for endometrial cancer involves removal of the uterus, tubes, ovaries, and lymph nodes. Few randomized trials have compared disease-free survival outcomes for surgical approaches. Objective: To investigate whether total laparoscopic hysterectomy (TLH) is equivalent to total abdominal hysterectomy (TAH) in women with treatment-naive endometrial cancer. Design, Setting, and Participants: The Laparoscopic Approach to Cancer of the Endometrium (LACE) trial was a multinational, randomized equivalence trial conducted between October 7, 2005, and June 30, 2010, in which 27 surgeons from 20 tertiary gynecological cancer centers in Australia, New Zealand, and Hong Kong randomized 760 women with stage I endometrioid endometrial cancer to either TLH or TAH...

INTRODUCTION: The electrothermal bipolar vessel-sealing device (BVSD) is known to supply a strong vessel-sealing power. However, only few studies have reported lymph node dissection (LND) using only BVSD during laparoscopic surgery for gastric cancer. The purpose of this study was to investigate the feasibility of LND using BVSD during reduced port laparoscopic distal gastrectomy for gastric cancer. METHODS: From May 2015, patients in whom three- or single-port laparoscopic distal gastrectomy had been engaged for gastric cancer were enrolled in this study...

BACKGROUND: Prolongation of survival in patients with breast cancer due to early diagnosis and modern methods of treatment has turned the attention on lymphedema, which is the most important morbidity secondary to the treatment of the disease. Determination of lymphedema and related risk factors in patients before a surgical intervention may provide protection for patients and early treatment. The aim of this study was to determine the presence of lymphedema before surgery by bioimpedance analysis in patients with breast cancer and to establish risk factors associated with lymphedema...

NUBPL is an assembly factor for human mitochondrial complex I, which is the biggest member of mitochondrial respiratory chain. However, the relationship between NUBPL and carcinoma progression remains unknown. In this study, NUBPL was characterized for its role in colorectal cancer (CRC) and the underlying molecular mechanisms. Data (n=197) from Oncomine database revealed that mRNA levels of NUBPL were remarkably overexpressed in CRC tissues compared with normal tissues. In addition, immunohistochemical analysis of 75 pairs of CRC and nontumorous tissues demonstrated that expression level of NUBPL was significantly higher in CRC tissues, and its expression level was positively associated with lymph node metastasis (P=0...

Chronic obstructive pulmonary disease (COPD) is associated with an increased risk for lung cancer and an aberrant microbiota of the lung. Microbial colonization contributes to chronic neutrophilic inflammation in COPD. Nontypeable Haemophilus influenzae (NTHi) is frequently found in lungs of stable COPD patients and is the major pathogen triggering exacerbations. The epithelial cytokine interleukin-17C (IL-17C) promotes the recruitment of neutrophils into inflamed tissues. The purpose of this study was to investigate the function of IL-17C in the pulmonary tumor microenvironment...

The aim of this study was to evaluate the histopathologic parameters that predict lymph node metastasis in patients with oral squamous cell carcinoma (OSCC) and to design a new assessment score on the basis of these parameters that could ultimately allow for changes in treatment decisions or aid clinicians in deciding whether there is a need for close follow-up or to perform early lymph node dissection. Histopathologic parameters of 336 cases of OSCC with stage cT1/T2 N0M0 disease were analyzed. The location of the tumor and the type of surgery used for the management of the tumor were recorded for all patients...

PURPOSE: Preoperative lymphoscintigraphy is the standard for the identification of sentinel lymph nodes (SLNs) in melanoma. The impact of negative scintigraphy [nonvisualization (NV) of the SLN] on surgical outcomes is inadequately reported in the literature. The objectives of this study were to determine the incidence, predictive factors, and surgical outcomes of NV in clinically node-negative melanoma patients. PATIENTS AND METHODS: A retrospective review of a prospective, Institutional Review Board approved, melanoma sentinel node database from January 2005 to August 2015 was performed...

An efficient evaluation of the lymphatic drainage from the breasts (thoracic wall) and/or the upper limbs is essential in the management of patients with breast cancer (BC) and/or BC-related lymphedema. Lymphoscintigraphy was performed in 2 patients with lymphedema. Lymphatic drainage was observed from the upper limb or breast to the posterior paravertebral and/or pararenal lymph nodes. The cases demonstrate lymphatic drainage pathways toward unusual and mostly unrecognized lymph nodes, which may be at risk for further evolution of BC and may be important for the physical treatment of BC-related lymphedema...

BACKGROUND: Cervical cancer is one of the most common cancers in women worldwide. Emerging evidence suggests that kin17 is a tumor-promoting protein in some types of solid tumors. However, whether kin17 contributes to cervical cancer carcinogenesis remains unknown. METHODS: Kin17 expression in clinical samples from Guangdong Women and Children's Hospital and Health Institute was detected by immunohistochemical staining. A series of functional experiments including 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay, 5-bromo-2'-deoxyuridine assay, colony formation, transwell assay, flow cytometry of apoptosis, and cell cycle were performed to explore the roles of kin17 in cervical cancer cells HeLa...

Melanocytic neoplasms are common in dogs and frequently occur within the oral cavity or in haired skin. The behavior of melanocytic neoplasms is variable and depends on tumor location, size, and histopathologic features. This study compared cytopathology and histopathology of 32 lymph nodes from 27 dogs diagnosed with melanocytic neoplasms. Agreement between the original cytology report, cytology slide review, original histopathology report, and histopathology slide review was determined for each lymph node...

Background: The sentinel lymph node (SLN) biopsy is a highly accurate predictor of overall axillary nodal status in early breast cancer patients. There is however, still a debate on which patients with a positive SLN can benefit from axillary lymph node dissection (ALND). Numerous studies have been designed to identify variables that are predictive of non-SLN metastasis to avoid a complete ALND. The aim of this study was to determine whether the pre-treatment neutrophil-lymphocyte ratio (NLR) can be a predictive factor of non-SLN metastasis in early breast cancer patients...
