Abstract
BACKGROUND To develop a clinical model for predicting high axillary nodal burden in patients with early breast cancer by integrating ultrasound (US) and clinicopathological features. METHODS AND MATERIALS Patients with breast cancer who underwent preoperative US examination and breast surgery at the Affiliated Hospital of Nantong University (centre 1, n = 250) and at the Affiliated Hospital of Jiangsu University (centre 2, n = 97) between January 2012 and December 2016 and between January 2020 and March 2022, respectively, were deemed eligible for this study (n = 347). According to the number of lymph node (LN) metastasis based on pathology, patients were divided into two groups: limited nodal burden (0-2 metastatic LNs) and heavy nodal burden (≥ 3 metastatic LNs). In addition, US features combined with clinicopathological variables were compared between these two groups. Univariate and multivariate logistic regression analysis were conducted to identify the most valuable variables for predicting ≥ 3 LNs in breast cancer. A nomogram was then developed based on these independent factors. RESULTS Univariate logistic regression analysis revealed that the cortical thickness (p < 0.001), longitudinal to transverse ratio (p = 0.001), absence of hilum (p < 0.001), T stage (p = 0.002) and Ki-67 (p = 0.039) were significantly associated with heavy nodal burden. In the multivariate logistic regression analysis, cortical thickness (p = 0.001), absence of hilum (p = 0.042) and T stage (p = 0.012) were considered independent predictors of high-burden node. The area under curve (AUC) of the nomogram was 0.749. CONCLUSION Our model based on US variables and clinicopathological characteristics demonstrates that can help select patients with ≥ 3 LNs, which can in turn be helpful to predict high axillary nodal burden in early breast cancer patients and prevent unnecessary axillary lymph node dissection.

Abstract
BACKGROUND The incidence of HBV-negative and HCV-negative hepatocellular carcinoma (NBNC-HCC) is significantly increasing. However, their clinicopathologic features and prognosis remain elucidated. Our study aimed to compare the clinicopathologic characteristics and survival outcomes of NBNC-HCC with hepatitis virus-related HCC. METHOD A literature review was performed in several databases, including PubMed, Embase, Cochrane Library and Web of Science, to identify the studies comparing NBNC-HCC with HBV-positive HCV-negative HCC (B-HCC), HBV-negative HCV-positive (C-HCC) and/or HBV-positive HCV-positive HCC (BC-HCC). The clinicopathologic characteristics and survival outcomes were extracted and pooled to access the difference. RESULTS Thirty-two studies with 26,297 patients were included: 5390 patients in NBNC-HCC group, 9873 patients in B-HCC group, 10,848 patients in C-HCC group and 186 patients in BC-HCC group. Patients in NBNC-HCC group were more liable to be diagnosed at higher ages, but with better liver functions and lighter liver cirrhosis. Comparing to B-HCC and C-HCC groups, although NBNC-HCC group was prone to have larger tumor sizes, it did not have more advanced tumors. Meanwhile, there were no significant differences in both 5-year and 10-year disease-free survival and overall survival between NBNC-HCC group and B-HCC or C-HCC group. CONCLUSIONS Our meta-analysis revealed patients with NBNC-HCC had as worse prognosis as those with hepatitis virus-related HCC. More attention should be paid on patients with non-alcoholic steatohepatitis or metabolic syndromes to prevent the incidence of NBNC-HCC.

Abstract
BACKGROUND The clinicopathological features, surgical outcomes, and long-term survival of patients with young-onset colon cancer (≤ 40 years old) remain controversial. METHODS The clinicopathologic and follow-up data of patients aged < 40 years with colon cancer between January 2014 and January 2022 were reviewed. The primary objectives were clinical features and surgical outcomes. Long-term survival was investigated as a secondary objective. RESULTS Seventy patients were included in the study, and no significant rising trend (Z=0, P=1) of these patients was observed over the 8-year study period. Stage IV disease was accompanied by more ulcerative or infiltrating type (84.2% vs. 52.9%, P=0.017) and lymphovascular or perineural invasion (64.7% vs. 25.5%, P=0.003) than stage I-III disease. After a median follow-up time of 41 months (range 8-99 months), the 1-, 3-, and 5-year estimated overall survival (OS) rates were 92.6%, 79.5%, and 76.4%, respectively. The 1-, 3-, and 5-year progression-free survival (PFS) rates were 79.6%, 71.7%, and 71.7%, respectively. Multivariate Cox regression showed that M+ stage (hazard ratio [HR], 3.942; 95% confidence interval [CI], 1.176-13.220, P=0.026) was the only independent risk factor affecting OS. Meanwhile, tumor deposits (HR, 4.807; 95% CI, 1.942-15.488, P=0.009), poor differentiation (HR, 2.925; 95% CI, 1.012-8.454, P=0.047), and M+ stage (HR, 3.540; 95% CI, 1.118-11.202, P=0.032) independently affected PFS. CONCLUSIONS The differences in the clinical features, surgical outcomes, and long-term survival between young adults and elderly colon cancer patients need further investigation.

Abstract
Evidence indicates that individual or groups of polybrominated diphenyl ethers (PBDEs) are associated with risk of breast cancer (BC). Epidemiological studies of PBDEs and BC progression are scarce. This study aimed to investigate the relationships between PBDE burdens in adipose tissues and prognostic biomarkers of BC as well as progression-free survival (PFS) of patients for the first time. The concentrations of 14 PBDE congeners in breast adipose tissues of 183 cases from the eastern area of southern China were analyzed by gas chromatography-mass spectrometry (GC-MS). Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by logistic regression models for the associations between PBDE levels and prognostic biomarkers. Kaplan-Meier and Cox regression analyses were conducted to identify the correlations between PBDEs and PFS. The results showed that BDE-99 and 190 levels were positively associated with clinical stage and N stage respectively (OR = 2.61 [1.26-5.40], OR = 2.78 [1.04-7.46]). Concentrations of BDE-28 and BDE-183 were negatively associated with the expression of estrogen receptor (ER) (OR = 0.30 [0.11-0.81]; 0.39 [0.15-0.99]) and progesterone receptor (PR) (OR = 0.36 [0.14-0.92]; 0.37 [0.15-0.91]), and increased BDE-47 was associated with lower human epidermal growth factor receptor 2 (HER2) expression (OR = 0.44 [0.23-0.86]). Adipose levels of BDE-71, 99, 138, 153, 154 and total PBDEs were positively associated with p53 expression (all P < 0.05). Finally, BDE-47, 99 and 183 were considered as independent prognostic factors for shorter PFS in the Cox models (adjusted hazard ratios = 3.14 [1.26-7.82]; 2.25 [1.03-4.94]; 2.60 [1.08-6.25], respectively). The recurrence risk and prognosis of BC may be closely bound to the body burdens of certain PBDE congeners. Further epidemiological and experimental studies are needed for confirmation.

Abstract
The literature on childhood tuberculous empyema (TE) is limited. The aim of this study was to examine the clinicopathological characteristics and outcome of paediatric TE and methods of prompt diagnosis and treatment. Between January 2014 and April 2019, 27 consecutive patients with TE aged ≤15 years [mean (SD) 12.2 (3.3), range 6-15] were retrospectively reviewed. The following were reviewed: baseline demographics, symptoms, laboratory and pathological examination, radiographical findings, microbiological data, anti-tuberculous and surgical treatment and clinical outcome. Acid-fast bacillus (AFB) smear, culture, TB real-time (RT) polymerase chain reaction (PCR) and T-SPOT.TB assay were reviewed. Six (60%) of 10 patients were TB-RT-PCR-positive in pus or purulent fluid. Twenty-three of 24 (95.8%) were T-SPOT.TB-positive. Decortication by surgical thoracotomy or thoracoscopy was performed in 22 (81.5%) patients. None of the 27 patients had specific complications such as pyopneumothorax or bronchopleural fistula and all were successfully treated. In childhood TE, aggressive surgical management is associated with a favourable outcome.Abbreviations: AFB, acid-fast bacilli; E, ethambutol; EPTB, extra-pulmonary TB; H, isoniazid; HIC, high-income countries; LMIC, low- and middle-income countries; MTB, Mycobacterium tuberculosis; PCR, polymerase chain reaction; PTB, pulmonary TB; R, rifampicin; RT, real time; TB, tuberculosis; TE, tuberculous empyema; Z, pyrazinamide.

Abstract
BACKGROUND Treatment for non-small cell lung cancer (NSCLC) has greatly improved in recent years. However, noninvasive early screening for carcinogenesis and progression unclear. The aim of this study was to explore the predictive value of peripheral blood immune cells in untreated NSCLC patients. METHODS We retrospectively enrolled 305 untreated NSCLC patients and 132 healthy participants from February 2016 to August 2019 in Peking Union Medical College Hospital. Immune cell levels were determined by flow cytometry and routine blood tests. RESULTS NSCLC patients had lower levels of T lymphocytes, NK cells, CD8+ T cells, naïve CD4+/CD4+, naïve CD4+ T cells and higher levels of CD4+ T cells, memory CD4+/CD4+ T cells, memory CD4+ T cells, CD4+CD28+/CD4+ T cells, CD4+CD28+ T cells, CD8+CD28+/CD8+ T cells, CD8+HLA-DR+/CD8+ T cells, CD8+HLA-DR+ T cells T cells, CD8+CD38+/CD8+ T cells, CD8+CD38+ T cells and CD4+/CD8+ T cells than those in controls. The percentages of specific lymphocyte subtypes were significantly different in cancer patients versus healthy individuals. For instance, cancer patients had lower levels of B cells, CD4+ T cells, naïve CD4+/CD4+ T cells, naïve CD4+ T cells, CD4+CD28+ T cells, CD8+CD28+ T cells and higher levels of NK cells, white blood cells (WBC), monocytes, neutrophils, eosinophils, basophils, monocytes to lymphocyte ratio (MLR), neutrophils to lymphocyte ratio (NLR), eosinophil to lymphocyte ratio (ELR), basophil to lymphocyte ratio (BLR), and blood platelet to lymphocyte ratio (PLR). CONCLUSIONS Abnormal T cell levels can be used as an independent predictive biomarker for noninvasive early screening in NSCLC occurrence and progression.

Abstract
Radiomic features from mammograms have been shown to predict breast cancer (BC) risk; however, their contribution to BC characteristics has not yet been explored. This study included 184 women with BC between January 2012 and April 2017. A set of 33 global radiomic features were extracted from the ipsilateral breast mammogram. Associations between radiomic features and BC characteristics were investigated by univariate logistic regression analysis, and receiver-operating characteristic curve analysis was employed to evaluate the predictive performance of radiomic features. Histogram-based features (mean, 70th percentile, and 30th percentile) weakly differentiated progesterone status and tumor size (AUC range: 0.627-0.652, p ≤ 0.007). One gray level run length matrix (GLRLM)-based feature achieved an AUC of 0.68 in discriminating lymph-node status, and the fractal dimension achieved an AUC of 0.65 in predicting tumor size. After stratifying by age at BC diagnosis and baseline percent density (PD), the average predictive performance of the abovementioned features improved from 0.652 to 0.707 for baseline PD adjustment, and from 0.652 to 0.674 for age at BC diagnosis. Higher predictive performances were found for GLRLM-based features in predicting lymph-node status among younger women with high baseline PD (AUC range: 0.710-0.863), and for fractal features in predicting tumor size among patients with low PD (AUC: 0.704). Global radiomic features from the ipsilateral breast mammogram can predict lymph-node status and tumor size among certain categories of women and should be considered as a non-invasive tool for clinical decision-making in BC-affected women and for forecasting disease progression.

Abstract
Aim of this study was to evaluate the association between multiple essential microelements exposure and the aggressive clinicopathologic characteristics of papillary thyroid carcinoma (PTC). The concentrations of 10 essential microelements in urine [cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), strontium (Sr), zinc (Zn), and iodine (I)] were measured in 608 patients newly diagnosed with PTC, including 154 males and 454 females. Chi square test and Wilcoxon rank sum test were used to compare general characteristics among males and females. Multivariate logistic regression was used to evaluate the associations between essential microelements and PTC clinicopathologic characteristics in single- and multi-microelement models. In this study, we only observed that the frequency of lymph node metastasis in males was higher than in females, and males had higher levels of zinc than females, but males had lower levels of iodine than females. It was found that high levels of Fe were associated with decreased risk of PTC tumor size > 1 cm, capsular invasion, and advanced T stage (T3/4a/4b). High levels of Co and Mo were associated with decreased risk of capsular invasion and lymph node metastasis, respectively. However, high levels of Mn and Sr were associated with increased risk of capsular invasion and multifocality respectively, and both were associated with increased risk of advanced T stage (T3/4a/4b). These findings indicated that certain essential microelements might have potential effects on PTC progression and aggressiveness. Further studies are required to confirm these findings.

Abstract
OBJECTIVES This study aimed to investigate the clinicopathologic features and subtype distribution of invasive breast cancer in elderly women (≥70 years of age). METHODS This retrospective study of 1,130 women compared the clinicopathologic characteristics and subtype distribution of invasive breast cancer in elderly (≥70 years) versus non-elderly (<70 years) women. Tumors were classified into five distinct subtypes based on the immunohistochemistry status of estrogen receptor (ER), progesterone receptor (PR), Ki67, and human epidermal growth factor receptor 2 (HER2). RESULTS The two patient groups did not differ significantly regarding ER and HER2 status. Breast cancers in elderly women were more likely to have negative PR status (40.4% vs. 32.6%, P=0.033) and low Ki67 expression (62.0% vs. 54.4%, P=0.047) than those in non-elderly women. Elderly women were less likely to undergo axillary lymph node dissection and axillary surgery (P<0.001). Consequently, unknown node status was more common in elderly women than non-elderly women (11.1% vs. 1.4%, respectively, P<0.001), while node involvement was less common in elderly women than non-elderly women (26.9% vs. 37.7%, respectively, P<0.001). There was no significant difference in the distribution of subtypes between the two groups. CONCLUSIONS Breast cancers in elderly women were less frequently node positive and more frequently PR negative and with low Ki67 expression than those in non-elderly women. Moreover, there was no difference in subtype distribution between the two age groups.

Abstract
Hub proteins related with Hippo signal pathway in glioma were investigated using proteomics methods (Tandem Mass Tag, TMT) to determine the differentially expressed proteins in glioblastoma (GBM). Ingenuity Pathway Analysis (IPA) was performed to complement proteomic findings by identifying the top canonical pathways as well as to suggest novel proteins for the targeted therapy of glioma. A total of 222 formalin-fixed paraffin-embedded (FFPE) glioma tissue samples were used to verify the expression of protein phosphatase 1γ (PP1γ), Yes-associated protein 1 (YAP1), and SOX2 via immunohistochemistry. Bioinformatics analysis revealed these proteins as crucial in the Hippo signaling pathway in GBM. Spearman correlation was performed to analyze the relationship of these three proteins, and survival analysis was conducted to investigate their effects on prognosis. Among the 5808 proteins identified by TMT with the standard of P-value < 0.05 and fold change (FC) of>1.2 or <0.83, 1398 upregulated and 1060 downregulated differentially expressed proteins were found. IPA revealed that the Hippo signaling was activated in the top 10 canonical pathways, and PP1γ was activated in the Hippo signaling. Immunohistochemistry analysis indicated that PP1γ, YAP1, and SOX2 were highly and positively expressed in glioma. PP1γ expression was related to WHO grade (p = 0.003) and ki-67 expression (p = 0.012). Low PP1γ expression was associated with IDH1-mut in low-grade glioma (LGG; WHO grades II and III) (p = 0.037). PP1γ was positively correlated with YAP1 (p < 0.001; r = 0.259) and SOX2 (p = 0.009; r = 0.175). In survival analysis, age, WHO grade, ki-67 expression, and PP1γ expression independently predicted a short OS in total cohort (p < 0.05). Therefore, PP1γ is a hub protein associated with Hippo signal pathway in glioma, and its expression indicates poor prognosis in patients with glioma. Therefore, PP1γ may be a promising prognostic biomarker and a therapeutic target in glioma.

Abstract
Background Previous studies reported that Epstein–Barr virus (EBV) may play a causal role in the pathogenesis of gastric remnant carcinoma (GRC). However, there was still some controversy. Methods Articles published until July 15, 2020, in PubMed, MEDLINE, Embase and CNKI databases were selected. According to the inclusion criteria, corresponding data of included articles were abstracted and used for statistical analysis. Results Thirteen papers were finally enrolled, nine of which showed the result that the risk of EBV infection rate in the GRC was higher than conventional gastric carcinoma (OR = 5.22, 95% CI 3.89–7.00). In addition, we found that EBV associated GRC (EBVaGRC) had higher rate of Billroth-II (OR = 3.80, 95% CI 1.90–7.57), carcinoma in anastomotic site (OR = 2.41, 95% CI 1.27–4.56) and diffuse type (Lauren classification) (OR = 1.97, 95% CI 1.04–3.73),while sex, initial diagnosis and lymphocytic infiltration were calculated no statistical difference. By genetic polymorphism analysis, “V-val” subtype of EBNA1 (OR = 21.84, 95% CI 11.92–31.76) and “C” subtype of BamHI-W1/I1 (OR = 7.07, 95% CI 1.47–34.03) were observed to be highly expressed in EBVaGRC. Conclusion EBV infection rate in the GRC was higher. Further analysis showed that Billroth-II, carcinoma in anastomotic site and diffuse type (Lauren classification) were associated to EBVaGRC. Through analysis of EBV genome polymorphisms, we thought that “V-val” subtype of EBNA1 and “C” subtype of BamHI-W1/I1 may become predictor of EBVaGRC.

Abstract
BACKGROUND The purpose of this study was to assess the risk factors for cancer-specific mortality and cardiovascular mortality in patients with diffuse large B-cell lymphoma (DLBCL). PATIENTS AND METHODS A retrospective cohort study involving patients with DLBCL who were registered in the Surveillance, Epidemiology, and End Results (SEER) database was performed. The risk factors for cancer-specific mortality and cardiovascular mortality were analyzed using the competing risk regression model. RESULTS A total of 62,950 patients with DLBCL were enrolled, of which 23,302 (37.50%) died of cancer and 2940 (4.70%) died of cardiovascular disease. The competing risk multivariate analysis displayed that age at diagnosis (hazard ratio [HR], 1.033; 95% confidence interval [CI], 1.032-1.034), marriedstatus (HR, 1.293; 95% CI, 1.241-1.347), black race (HR, 1.079; 95% CI, 1.021-1.139), and tumor stage (II: HR, 1.143; 95%CI, 1.095-1.192; III: HR, 1.459; 95% CI, 1.395-1.526; IV: HR, 1.961; 95% CI. 1.889-2.035) were the risk factors for cancer-specific mortality, but not female gender (HR, 0.938; 95% CI, 0.913,0.965) or treatment modalities (chemotherapy: HR, 0.522; 95% CI, 0.505-0.540; radiotherapy: HR, 0.782; 95% CI, 0.728-0.839; chemotherapy + radiotherapy: HR, 0.422; 95% CI, 0.403-0.441). Age at diagnosis (HR, 1.059; 95% CI, 1.055-1.062) and black race (HR, 1.246; 95% CI, 1.067-1.456) were the risk factors for cardiovascular mortality rather than female gender (HR, 0.803; 95% CI, 0.743-0.867) and married status (HR, 0.841; 95% CI, 0.745-0.950). CONCLUSIONS Age at diagnosis, married status, black race, and higher tumor stage are associated with an increased risk of cancer-specific mortality in patients with DLBCL, whereas age at diagnosis and black race are associated with a higher risk of cardiovascular mortality.

Abstract
OBJECTIVES The aim of this systematic review was to provide an overview of the oral and maxillofacial solitary fibrous tumor (SFT) in order to determine its clinicopathologic characteristics and biological behavior. METHODS We conducted a systematic review in May 2019 in multiple databases. Cases diagnosed as SFT in the oral cavity and maxillofacial complex were included. RESULTS Seventy-three published articles were included in our systematic review, corresponding to a total of 154 cases. SFT showed a slight female predilection (53.2%), and the cheek mucosa/cheek, tongue, and palate were the most affected anatomical sites. The mean size of SFT in the oral cavity and maxillofacial region at diagnosis was 1.4 cm. Histologic features of malignancy by morphologic analysis (P < .001) were significantly associated with a larger tumor size. Surgical excision was the most frequent therapeutic modality. Recurrence and metastasis were uncommon findings in our sample. CONCLUSIONS Histologic features of malignancy can be important parameters of tumor behavior. Adequate surgical treatment and long-term follow-up are required for these cases.

Abstract
This study aimed to investigate the hub protein related to the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT) signaling pathway in diffuse large B-cell lymphoma (DLBCL). We used proteomics methods (iTRAQ) to explore the differentially expressed proteins in the non-germinal center B-cell -like (non-GCB) DLBCL in our previous study. In this study, a total of 137 formalin-fixed paraffin-embedded DLBCL tissue samples were analyzed via immunohistochemistry to verify the expression of TCL1, AKT1 + 2+3, IKKβ and to determine the differentially expressed proteins associated with the PI3K/AKT signaling pathway. Spearman correlation was used to analyze the relationship between these proteins, and survival analysis was used to investigate their effects on prognosis. Immunohistochemistry analysis indicated that TCL1, AKT1 + 2+3, and IKKβ were highly positively expressed in DLBCL. Results showed that the expression of TCL1 was related to ethnicity (p = 0.022), primary site (p = 0.045), Ann Arbor stage (p = 0.037), the International Prognostic Index (p = 0.005), β2-microglobulin (p = 0.030), BCL2 expression (p < 0.001), and Ki-67 expression (p = 0.008). A positive correlation was found between TCL1 and AKT1 + 2+3 (p < 0.001; r = 0.475). A positive correlation was also found between AKT1 + 2+3 and IKKβ (p < 0.001; r = 0.342). In survival analysis, anemia, non-treatment with R‑CHOP, positive TCL1 expression, and Ki-67 expression≥50% independently predicted short progression-free survival and overall survival in the total cohort (p < 0.05). Thus, TCL1 as a hub protein is associated with the PI3K/AKT signaling pathway in DLBCL. TCL1 expression indicated a poor prognosis in patients with DLBCL. With further studies, TCL1 may be established as a reliable prognostic biomarker and potential immunotherapeutic target for improving therapeutic efficacy for DLBCL in the future.

Abstract
BACKGROUND MicroRNA (miRNA)-382-5p functions as an oncogenic miRNA in breast cancer. MXD1 was demonstrated to be one of its direct targets. However, the involvement of miRNA-382-5p/MXD1 axis in breast cancer remains unknown. The aim of this study was to investigate the expression pattern, clinical significance, and potential functions of miRNA-382-5p/MXD1 axis in breast cancer. MATERIALS AND METHODS Quantitative polymerase chain reaction was performed to detect the expression levels of miRNA-382-5p and MXD1 messenger RNA (mRNA) in 96 pairs of breast cancer and matched noncancerous breast tissue samples from the same patients. Relationships between miRNA-382 expression, MXD1 expression, and combined miRNA-382-5p and MXD1 expression, and various clinicopathological characteristics of breast cancer were statistically evaluated, and their roles in breast cancer cell proliferation and invasion were also examined. RESULTS Compared with noncancerous breast tissues, miRNA-382-5p expression was upregulated but MXD1 mRNA expression was downregulated in breast cancer tissues (both P < 0.01). High miRNA-382 expression, MXD1 expression, and combined miRNA-382-5p and low MXD1 expression were significantly associated with advanced tumor stage and the presence of lymph node metastasis (all P < 0.05). Overexpression of miRNA-382-5p dramatically reduced MXD1 mRNA and protein expression levels in breast cancer cells. miRNA-382-5p upregulation markedly enhanced breast cancer cell proliferation and invasion, while its downregulation inhibited these malignant phenotypes of breast cancer cells in vitro. Notably, overexpressed MXD1 reversed the effects of upregulated miRNA-382-5p on cell proliferation and invasion in vitro. CONCLUSIONS The dysregulation of miRNA-382-5p-MXD1 axis may be involved in the development and aggressive progression of breast cancer. miRNA-382-5p may target MXD1, leading to cell invasion and proliferation in breast cancer cells in vitro, implying its potentials as a therapeutic target for this type of cancer.

Abstract
BACKGROUND Previous studies have shown that prealbumin (PA) and fibrinogen (Fib) can be used to predict the clinicopathological features and prognosis of a variety of malignant tumors. Therefore, we speculated that the prealbumin-to-fibrinogen ratio (PA/F) can predict the clinicopathological features of patients with gastric cancer (GC) and tumor progression preoperatively.
AIM To explore the relationship between the PA/F ratio and clinicopathological features of patients with GC.
METHODS The preoperative clinical and pathological data of 210 patients with GC admitted to the First Affiliated Hospital of Zhejiang University from January 2017 to March 2019 were retrospectively analyzed. The patients were divided into either a low PA/F group or high PA/F group. The differences in clinical data and pathological features were compared between the two groups, and the correlation between PA/F values and other prognosis-related immunonutrient indicators was also analyzed.
RESULTS The PA/F ratio was significantly associated with age, tumor size, degree of differentiation, depth of invasion, lymph node metastasis, TNM stage, and neurovascular invasion (P < 0.05). The low PA/F value group showed greater age, larger tumor diameter, lower degree of differentiation, deeper infiltration, advanced TNM stage, and more frequent neurovascular invasion (P < 0.05). PA/F values were negatively correlated with multiple immune nutrition indicators, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein-to-albumin ratio (CAR), and systemic immune-inflammation index (SII), but positively correlated with prognostic nutritional index (PNI).
CONCLUSION The PA/F ratio can be used as a predictor of preclinical clinicopathological features in patients with GC, and patients with a PA/F ratio ≤ 9.07 have a relatively poor prognosis. The PA/F value is associated with NLR, PLR, CAR, SII, and PNI.

Abstract
OBJECTIVES We investigated and compared clinicopathologic features and subtype distribution of invasive breast cancer among women <40 and ≥40 years of age. METHODS We retrospectively compared clinicopathologic characteristics and subtype distribution of invasive breast cancer in women <40 and ≥40 years of age, in a cohort of 1,130 patients. Subtypes included luminal A (positive for hormone receptors [HR]-estrogen receptor [ER] and/or progesterone receptor [PR]-and negative for human epidermal growth factor receptor 2 [HER2] with low Ki67), luminal B (HER2-) (HR+/HER2-/Ki67High), luminal B (HER2+) (HR+/HER2+), HER2-overexpressing (HR-/HER2+), and triple negative (ER-/PR-/HER2-). RESULTS Breast cancers in younger women had unfavorable clinicopathologic characteristics, including larger tumors and more frequent node involvement. Subtypes among the 1,130 tumors were luminal A: 36.4%, luminal B (HER2-): 35.0%, luminal B (HER2+): 7.5%, HER2-overexpressing: 7.1%, and triple negative: 14.0%. The age groups significantly differed in subtype distribution (P<0.001). Luminal A subtype was more common in the older group (38.5%) than the younger group (16.2%), and luminal B (HER2-) was more common in the younger group (52.2%) than in the older group (33.2%; P<0.001). CONCLUSIONS Breast cancers in women younger than 40 years have unfavorable clinicopathologic characteristics and are more likely to be luminal B (HER2-) and less likely to be luminal A than breast cancers in older women.

Abstract
Polybrominated diphenyl ethers (PBDEs) are suspected to be associated with breast cancer risk because of their estrogenic potencies. Epidemiological studies of PBDEs and breast cancer are scarce. Our study aimed to estimate the association between adipose-tissue PBDE concentrations and breast cancer risk. A total of 209 breast cancer cases and 165 controls were recruited from hospitals between January 2014 and May 2016 in Shantou, Chaoshan area, China. Concentrations of 14 PBDE congeners were measured in adipose tissues obtained from the breast for cases and the abdomen/breast for controls during surgery. Demographic and clinicopathologic characteristics were obtained from medical records. Breast cancer risk as well as clinicopathologic characteristics were evaluated by adipose-tissue PBDE level. Odds ratios (ORs) and 95% confidence intervals (95% CIs) for breast cancer risk associated with levels of PBDE congeners were estimated from logistic regression models for all cases and stratified by estrogen receptor (ER) status. Level of total PBDEs (∑PBDE) and most individual PBDE congeners were higher in breast cancer cases than controls (median ∑PBDE, 94.99 vs 73.72 ng/g lipid). In the adjusted univariate model for all cases, breast cancer risk was increased with both 2nd and 3rd tertiles versus the 1st tertile of BDE-47 level (OR 2.05 [95% CI 1.08-3.92]; 5.47 [2.96-10.11]) and BDE-209 level (2.48 [1.30-4.73]; 4.72 [2.52-8.83]) with trend (both P < 0.001) and with the 3rd tertile of BDE-28 level (2.83 [1.63-4.92]), BDE-99 (3.22 [1.85-5.60]), BDE-100 (5.45 [2.90-10.23]), BDE-138 (2.40 [1.37-4.20]), BDE-153 (1.74 [1.02-2.97]), BDE-154 (1.84 [1.05-3.22]), and ∑PBDE levels (1.83 [1.07-3.14]) but decreased with the 3rd tertile of BDE-71 level (0.38 [0.22-0.65]) with trend (all P < 0.01). After stratifying by ER-positive or -negative status, the adjusted results were similar for ER-positive patients except for BDE-153 and BDE-154, with no statistical significance. In the multivariate model for all cases, age, menarche age, BDE-47, 71, 99, 100, 183 and 209 were independent factors associated with breast-cancer risk. ∑PBDE and most individual PBDE congeners investigated were positively associated with breast cancer risk in women from the Chaoshan area, China. PBDE may play a role in the occurrence and development of breast cancer.

Abstract
Papillary thyroid carcinoma (PTC) is the most common malignant tumour of the thyroid. The effect of the concurrent presence of Hashimoto's thyroiditis (HT) and PTC is still under debate. The aim of this study is to investigate the influence of coexistent HT on prognostic outcomes and the association of coexistent HT with clinicopathological features. The demographic and clinicopathological data of 1,392 patients who underwent surgery in our hospital from 2007 to 2016 was collected and analysed. Among 1,392 PTC patients, the rate of HT was 25.6%. There were significant differences in the mean levels of thyroid stimulating hormone (3.27 vs. 2.41 μIU/L, p < 0.01), thyroperoxidase antibodies (110.31 vs. 131.2 U/ml, p < 0.01) and thyroglobulin antibodies (131.90 vs. 113.53 ng/ml, p < 0.01) between the two groups. PTC patients with HT had the following characteristics compared to patients without HT: smaller tumour size (p < 0.01), female predominance (p < 0.01) and higher rate of multifocality (p = 0.024). In addition, patients with HT had a significantly lower rate of lymph node metastasis (LNM) and advanced TNM stage than patients without HT (all p < 0.01). Multivariate analysis found that both age and multifocality were significantly associated with central LNM in HT patients (p < 0.01, p = 0.019, respectively). Extrathyroidal invasion and TSH level were also significant independent factors for lateral LNM in HT patients (p < 0.008, p = 0.04, respectively). HT is associated with a significantly higher risk of PTC. The coexistence of HT in PTC patients is associated with favourable clinical outcomes compared to PTC without HT. Total thyroidectomy and prophylactic central compartment lymphadenectomy should be a choice for PTC patients with HT.

Abstract
Background The aim of the study was to investigate the effect associated with the protein expression of VEGF, JAK2 and STAT3 on the clinicopathologic characteristics and prognosis in the development and progression of nasopharyngeal carcinoma (NPC). Methods Fifty NPC patients in addition to 20 patients with chronic nasopharyngitis (CNP) were recruited for the purposes of the study. Western blotting and immunohistochemistry methods were employed to evaluate the protein expressions of JAK2, STAT3 and VEGF in the NPC and CNP tissues, with their respective correlations with the clinicopathologic characteristics of NPC patients subsequently analyzed. Spearman’s rank correlation coefficient and Kaplan–Meier method were conducted to evaluate the respective correlations of JAK2, STAT3 and VEGF with NPC as well as the survival rates of patients with NPC. Cox regression analyses was performed in determine the prognostic NPC factors. Results Compared with the CNP tissues, the NPC tissues exhibited elevated levels of JAK2, STAT3 and VEGF which were subsequently determined to share a positive correlation with T stages, lymph node metastasis (LNM), N stages and clinical stages, while a negative correlation with survival rates were observed in the NPC patients. Positive correlations between the expressions of JAK2, STAT3 and VEGF were detected among the NPC tissues. NPC patients survival time with negative expressions of JAK2, STAT3 and VEGF were observed to be longer than that of NPC patients with positive expressions of JAK2, STAT3 and VEGF. T stage, LNM, N stage, clinical stage. The expressions of JAK2, STAT3 and VEGF were discovered to be independent risk factors associated with the prognosis of patients with NPC. Conclusion The results obtained from the present study support the notion that higher expressions of JAK2, STAT3 and VEGF may be correlated with the clinicopathologic characteristics and prognosis of patients suffering from NPC.

Abstract
BACKGROUND Giant serpentine aneurysms (GSAs) are a subgroup of giant intracranial aneurysms, distinct from saccular and fusiform varieties, that are defined as partially thrombosed giant aneurysms with tortuous internal vascular channel. Clinicopathologic characteristics of middle cerebral artery GSAs have been rarely reported in the literature, with discussion of radiologic characteristics only. We clarify patient clinical and neuroradiologic features and discuss the mechanism of formation and progression. CASE DESCRIPTION A 43-year-old woman presented with a GSA arising from the middle cerebral artery. There was a separate inflow and outflow channel of the aneurysm, with the outflow channel feeding the distal branches of the parent artery and supplying normal brain parenchyma. The GSA was treated successfully by aneurysmectomy and superficial temporal artery-middle cerebral artery bypass followed by proximal occlusion and vascular reconstruction. An aneurysm specimen was examined to correlate pathologic findings and morphologic characteristics. RESULT Pathologic results showed that thickness of the aneurysmal wall was typically increased and varied, and no internal elastic lamina or endothelial lining could be identified. The sac contained thrombi of various ages with recanalizing vessel formation and chronic inflammation infiltration. Intimal hyperplasia and neoangiogenesis in the wall and hyaline degeneration of the media were observed. Vessels coursing in their adventitia showed mucoid changes, which are responsible for the contrast enhancement of the aneurysmal rim on computed tomography scan. CONCLUSIONS GSAs are a specific pathologic entity with unique morphologic and pathologic characteristics that can affect intracranial blood vessels. The pathogenic mechanisms are unclear; this report suggests that GSAs may be associated with degeneration of the vascular wall.

Abstract
PURPOSE To examine the clinicopathologic characteristics and survival outcomes of different histologic types of triple-negative breast cancer (TNBC). METHODS We used the SEER database to identify patients with TNBC diagnosed between 2010 and 2014. Our analysis focused on the seven most prevalent histologic types. Differences were compared between invasive carcinoma of no special type (NST) and the other six types. RESULTS Significant differences were observed in age at diagnosis, tumor grade, size, nodal status and treatment. As tumor size increased, the number of positive lymph nodes increased markedly in invasive lobular carcinoma (ILC) and mixed NST and lobular carcinoma (NST-ILC), while in metaplastic carcinoma the number only increased slightly. In multivariate survival analyses, compared with patients with invasive carcinoma NST, breast cancer-specific survival (BCSS) and overall survival (OS) were worse for those with NST-ILC (BCSS: hazard ratio [HR] 1.81, P < .001; OS: HR 1.56, P = .005) or metaplastic carcinoma (BCSS: HR 1.95, P < .001; OS: HR 1.73, P < .001). By contrast, patients with medullary (HR 0.40, P = .010) or apocrine carcinoma (HR 0.27, P = .008) showed better BCSS. Time-dependent receiver operating characteristic (ROC) analyses indicated that T category in ILC and N category in metaplastic carcinoma were of less prognostic value. CONCLUSIONS According to the histologic classification of TNBC, this heterogeneous disease can be divided into several entities with different clinicopathologic features and prognoses. In the era of molecular subtyping of breast cancer, the histologic classification of TNBC is still of considerable clinical significance.

Abstract
Distant metastasis is strongly associated with poor prognosis of breast cancer. Cadmium (Cd) exposure was previously found associated with breast cancer incidence. We explored the associations of blood cadmium levels (BCLs) and clinicopathologic characteristics with invasive breast cancer distant metastasis. Blood samples were collected and analyzed for BCLs by graphite-furnace atomic absorption spectrometry. Clinicopathologic characteristics, including basic clinical information and tumor characteristics, were obtained from medical records. Breast cancer distant metastasis-free survival (DMFS) time was calculated at follow-up. The associations of BCLs and clinicopathologic characteristics with DMFS time were examined by Kaplan-Meier method and Cox regression analysis, and associations between BCLs and tumor characteristics were also explored. Blood Cd level was positively associated with distant metastasis, clinical stage, BMI, and age. On univariate analysis, older age at diagnosis, family history of breast cancer, high N classification and clinical stage, positivity for human epidermal growth factor receptor 2, and high BCLs were associated with short DMFS time. On multivariate analysis model, older age at diagnosis, family history of breast cancer, high N classification, and BCLs were predictors for breast cancer distant metastasis. BCLs were a risk factor for short DMFS time of invasive breast cancer. BCLs and some clinicopathologic factors affect breast cancer distant metastasis, which needs further epidemiological and experimental studies to confirm.

Abstract
OBJECTIVE To evaluate the predictive value of serum HE4 and CA125 concentrations in the preoperative prediction of risk of lymph node metastasis in endometrial cancer. METHODS A retrospective study was undertaken of data for patients with endometrial carcinoma treated surgically at a university hospital in China between August 2011 and December 2015. The preoperative serum levels of HE4 and CA125 were measured and analyzed by clinicopathologic characteristics. RESULTS Overall, 258 patients were included. The HE4 and CA125 concentrations were significantly elevated in patients with large lesions (≥2 cm), deep myometrial invasion (≥50%), an advanced disease stage, or lymph node metastasis (P<0.05 for all). HE4 concentrations also rose with age and histologic grade (P<0.01 for both). For lymph node metastasis, HE4 had higher sensitivity and negative predictive value than did CA125. The diagnostic performance of HE4 and CA125 in combination was superior to that of either marker alone. CONCLUSION The combined evaluation of serum HE4 and CA125 could provide gynecologic oncologists with improved information to guide the decision of whether to perform lymphadenectomy.

Abstract
OBJECTIVES Gastric cancer (GC) in young patients is thought to exhibit a worse prognosis due to specific clinicopathologic characteristics and delayed diagnosis; however, the data are controversial. This study aimed to analyse the clinicopathologic characteristics and prognostic factors of GC in young patients and to determine whether GC is a different clinical entity in younger vs. older patients. PATIENTS AND METHODS Clinical data of 3930 gastric cancer patients who underwent radical gastrectomy were retrospectively analysed and divided into two age groups. The younger group consisted of 342 cases of patients aged 40 years or younger at the time of surgery, and the older group included 3588 cases of patients older than 40 years. Clinicopathologic characteristics were compared using Pearson's χ(2) or Fisher's exact tests, and survival curves were constructed using the Kaplan-Meier method. RESULTS Clinicopathologic characteristics of the younger group exhibited a predominance of females (p < 0.001), diffuse stomach lesions (p = 0.014), signet-ring cell type (p < 0.001), poorly differentiated histological tumours (p < 0.001), Borrmann type IV (p < 0.001), mixed Lauren's classification types (p = 0.004), and recurrence rate in the gastric remnant (p < 0.001). The overall 5-year survival rates in the younger group and older group were 60.8% and 53.7%, respectively (p = 0.017). When stratified by TNM stage, the younger group exhibited enhanced 5-year survival at stage IV compared with the older group (26.9% VS. 10.3%, p = 0.003). CONCLUSION Although younger patients with GC exhibit more aggressive cancer patterns and higher recurrence rate in the gastric remnant, the overall 5-year survival rate may be better than older patients.

Abstract
AIM We aimed to study the expression of CD24 and CD133 in colorectal cancer and normal adjacent tissues to assess a relationship between these markers and clinic-pathological characteristics and patient's survival. BACKGROUND Cancer stem cells are a group of tumor cells that have regeneration and multi-order differentiation capabilities. PATIENTS AND METHODS Expression of CD24 and CD133 was studied in a paraffin block of colorectal cancer and normal tissues near tumors with the immuneohistochemical method in patients who were referred to Imam Khomeini Hospital in Sari. RESULTS A total of 50 samples (25 males and 25 females) with a mean age of 67.57±13.9 years old with range 28-93 years, included 3 mucinous carcinoma and 47 adenocarcinoma. Expression of CD133 marker was negative in 29 cases and positive in 21 cases. Expression of CD24 in tissue near tumor cells was found in 30% of available samples. The relationship between expressing CD24 with treatment (surgery and chemotherapy) was significant and its relationship with patient's survival was insignificant statistically. However, there was a clear difference as mean survival age of patients based on CD24 expression was 26.64±18.15 for negative cases and 41.75±28.76 months for positive cases. CD24 and CD133 expressions and their co-expression with other clinic-pathological factors were not significant. CONCLUSION During this study, the relationship between CD24 and treatment type was significant. To confirm this result, various studies with high sample numbers and other stem cell markers are recommended.

Abstract
AIM: To evaluate the prognostic role of p53 status and its relationship with clinicopathologic characteristics in esophagus squamous cell carcinoma (ESCC).
METHODS: A systematic search of PubMed, SCI-Ex-panded, EMBASE, the Cochrane library, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Database (CBM), and science and technology periodical database (VIP) was performed. Related references were also searched for additional clinical studies. Two reviewers independently performed screening of identified studies and data extracting according to inclusion and exclusion criteria. The quality assessment was conducted on the basis of the Newcastle-Ottawa Quality Assessment Scale (NOS). The evaluation of the publication bias of the included studies and data synthesis were performed with RevMan 5.3. A fixed-effect or random effects model was adopted according to heterogeneity.
RESULTS: A total of 85 studies involing 8825 cases met the inclusion criteria. The experimental group (4608 cases) was positive for either p53 gene mutation or protein expression, and the control group (4217 cases) was negative for either p53 gene mutation or protein expression. The pooled hazard ratio (HR) for OS was 1.35 (95%CI: 1.23-1.47, P < 0.00001; heterogeneity: P = 0.39, I2 = 5%). The pooled risk ratio (RR) for the 5-year and 3-year survival rates was 0.73 (95%CI: 0.62-0.87, P = 0.0003; heterogeneity: P = 0.001, I2 = 50%) and 0.87 (95%CI: 0.74-1.02, P = 0.09; heterogeneity: P = 0.28, I2 = 18%). p53 gene mutation or protein expression was significantly associated with poorer T stage (RR = 1.09, P = 0.004), N stage (RR = 1.24, P < 0.00001), M stage (RR = 1.65, P < 0.00001), TNM stage (RR = 1.25, P < 0.00001) and differentiation degree (RR = 1.06, P = 0.03). However, there were no association between P53 status and vascular invasion, tumor location, size, age or gender in ESCC (P>0.05).
CONCLUSION: p53 gene mutation or protein expression abnormality is a marker of poor prognosis in patients with ESCC. Meantime, patients with P53 abnormalities are associated with higher depth of invasion, higher rate of lymph node metastasis and distant metastasis, later TNM stage, and poorer grade of differentiation.

Abstract
It is unclear whether familial non-medullary thyroid carcinoma (FNMTC) is more aggressive than sporadic carcinoma, and its prevalence is still under debate. In this study, we investigated the clinicopathologic features of familial papillary thyroid carcinoma (PTC) compared with its sporadic counterpart. We used data from our hospital between 2008 and 2014 to compare the features of 24 familial PTC with 80 sporadic PTC. The prevalence of familial PTC was 1.5%; 25% of familial PTC exhibited a parent-offspring relationship, and 75% exhibited a sibling relationship. There were significant differences in terms of Hashimoto's thyroiditis, nodular goiter, multicentricity, bilaterality, histologic variant, T stage and N stage between the familial and sporadic PTC groups (all p < 0.05). When we compared sporadic PTC with parent-offspring or sibling familial PTC separately, parent-offspring familial PTC was more Hashimoto's thyroiditis and central LNM, while sibling familial PTC was more prevalent in multifocality and bilaterality than sporadic PTC. The recurrence rate was not significantly higher than that of sporadic PTC in familial PTC. The second generation in parent-offspring familial PTC patients exhibited an earlier age at diagnosis, greater multifocality and a higher metastasis rate than the first generation. Based on our results, we conclude that familial PTC is a clinically distinct entity with an aggressive nature. Because of the frequent presence of benign nodules, multifocality, bilaterality and high rate of recurrence, total or near-total thyroidectomy with neck dissection in these patients might be recommended. To date, the optimal clinical treatment is yet to be established, but improved awareness and screening will permit earlier detection, more timely intervention and improved outcomes for patients and their families.

Abstract
Alterations in telomere dynamics have emerged as having a causative role in carcinogenesis. Both the telomere attrition contribute to tumor initiation via increasing chromosomal instability and that the telomere elongation induces cell immortalization and leads to tumor progression. The objectives of this study are to investigate the dynamics of telomere length in colorectal cancer (CRC) and the clinicopathological parameters implicated. We measured the relative telomere length (RTL) in cancerous tissues and in corresponding peripheral blood leukocytes (PBL) using quantitative PCR (Q-PCR) from 94 patients with CRC. Telomere length correlated significantly in cancer tissues and corresponding PBL (r = 0.705). Overall, cancer tissue had shorter telomeres than PBL (p = 0.033). In both cancer tissue and PBL, the RTL was significantly correlated with age groups (p = 0.008 and p = 0.012, respectively). The RTL in cancer tissue was significantly longer in rectal tumors (p = 0.04) and in the late stage of tumors (p = 0.01). In PBL, the RTL was significantly correlated with the macroscopic aspect of tumors (p = 0.02). In addition, the telomere-length ratio of cancer to corresponding PBL increased significantly with late-stage groups. Shortening of the telomere was detected in 44.7%, elongation in 36.2%, and telomeres were unchanged in 19.1% of 94 tumors. Telomere shortening occurred more frequently in the early stage of tumors (p = 0.01). This study suggests that the telomere length in PBL is affected by the macroscopic aspect of tumors and that telomere length in cancer tissues is a marker for progression of CRC and depends on tumor-origin site.

Abstract
AIM: To explore the association between AT-rich interactive domain 1A (ARID1A) protein loss by immunohistochemistry and both clinicopathologic characteristics and prognosis in patients with colorectal cancer.
METHODS: We retrospectively collected clinicopathologic data and archived paraffin-embedded primary colorectal cancer samples from 209 patients, including 111 patients with colon cancer and 98 patients with rectal cancer. The tumor stage ranged from stage I to stage IV according to the 7th edition of the American Joint Committee on Cancer tumor-node-metastasis (TNM) staging system. All patients underwent resection of primary colorectal tumors. The expression of ARID1A protein in primary colorectal cancer tissues was examined by immunohistochemical staining. The clinicopathologic association and survival relevance of ARID1A protein loss in colorectal cancer were analyzed.
RESULTS: ARID1A loss by immunohistochemistry was not rare in primary colorectal cancer tumors (25.8%). There were 7.4%, 24.1%, 22.2% and 46.3% of patients with ARID1A loss staged at TNM stage I, II, III and IV, respectively, compared with 20.0%, 22.6%, 27.7% and 29.7% of patients without ARID1A loss staged at TNM stage I, II, III and IV, respectively. In patients with ARID1A loss, the distant metastasis rate was 46.3%. However, only 29.7% of patients without ARID1A loss were found to have distant metastasis. In terms of pathologic differentiation, there were 25.9%, 66.7% and 7.4% with poorly, moderately and well differentiated tumors in patients with ARID1A loss, and 14.2%, 72.3% and 13.5% with poorly, moderately and well differentiated tumors in patients without ARID1A loss, respectively. ARID1A loss was associated with late TNM stage (P = 0.020), distant metastasis (P = 0.026), and poor pathological classification (P = 0.035). However, patients with positive ARID1A had worse overall survival compared to those with negative ARID1A in stage IV colorectal cancer (HR = 2.49, 95%CI: 1.13-5.51).
CONCLUSION: ARID1A protein loss is associated with clinicopathologic characteristics in colorectal cancer patients and with survival in stage IV patients.

Abstract
AIM: To investigate the expression of zinc finger protein 139 (ZNF139) in gastric cancer (GC), and to analyze its clinical significance.
METHODS: A total of 108 patients who were diagnosed with GC and underwent surgery between January 2005 and March 2007 were enrolled in this study. Gastric tumor specimens and paired tumor-adjacent tissues were collected and paraffin-embedded, and the clinicopathologic characteristics and prognosis were recorded. The expression of ZNF139, Bcl-2, Bax, and caspase-3 were determined by immunohistochemistry, and apoptosis was assessed by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling. SPSS 13.0 software was used for data processing and analyses, and significance was determined at P < 0.05.
RESULTS: The expression of ZNF139 was stronger in tumors than in tumor-adjacent tissues (66.67% vs 44.44%; P < 0.01). Overexpression of ZNF139 correlated with tumor differentiation, invasion depth, clinical stage, lymphatic metastasis, and blood vessel invasion (all Ps < 0.05). Patients with overexpression of ZNF139 had a poorer prognosis (P < 0.01), and overexpression of ZNF139 was an independent factor for the prognosis of GC patients by a Cox survival analysis (P = 0.02). A negative relationship between ZNF139 and the apoptosis index was observed (r = -0.686; P < 0.01). The expression of Bcl-2 in GC was stronger than in tumor-adjacent tissues (66.67% vs 41.67%), whereas the expression levels of Bax and caspase-3 were lower in primary tumors (54.63% and 47.22%, respectively) than in tumor-adjacent tissues (73.15% and 73.15%, respectively) (all Ps < 0.05). The expression of ZNF139 negatively correlated with caspase-3 (r = -0.370; P < 0.01). The expressions of Bcl-2 and Bax were also negatively correlated (r = -0.231; P = 0.02). The expressions of caspase-3 and Bax protein were positively correlated (r = 0.217; P = 0.024).
CONCLUSION: ZNF139 is related to clinicopathologic characteristics and prognosis of GC. Furthermore, it is overexpressed and involved in apoptosis in GC tissues by regulating caspase-3.

Abstract
BACKGROUND Bone metastasis (BM) is reported as a poor prognostic factor in gastric cancer. However, the clinicopathologic characteristics and clinical outcomes of patients with BM compared with patients without BM have not been well described. PATIENTS AND METHODS The medical records of all metastatic or recurrent gastric cancer (MRGC) patients who visited our institution were reviewed. A total of 137 evaluable patients with BM were analysed together with historical control without BM (N=111). RESULTS Of 1342 MRGC patients, 141 (10.5%) had BM. Patients with BM could be divided into initial BM (BM present at initial diagnosis of MRGC; N=90) and late BM (N=47) groups. The median survival after the diagnosis of BM in all patients was 4.4 months (95% confidence interval [CI] 3.69-5.11). However, overall survival after the diagnosis of MRGC was significantly shorter in the initial BM group (5.0 versus 12.2 months, p<0.001). Compared with historical controls, patients with initial BM showed distinct clinicopathologic characteristics. Independent predictors of initial BM were a younger age, signet ring cell histology, primary tumour involving ⩾two-thirds of the stomach, pleural metastasis, thrombocytopenia and elevated alkaline phosphatase. According to a Cox proportional hazard model including both patients with BM and historical controls, initial BM, poor performance status, peritoneal metastasis, hypercalcemia and high carcinoembryonic antigen (CEA) were identified as poor prognostic factors, whereas chemotherapy was identified as a favourable factor (hazard ratio [HR] 0.33, 95% CI 0.22-0.49). CONCLUSION MRGC with initial BM is a distinct group of diseases with specific clinicopathologic characteristics and poor prognosis. Chemotherapy may improve survival in these patients.

Abstract
PURPOSE To clarify the clinical significance of microRNA-31 (miR-31) and radixin (RDX) in human glioma. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) analysis was used to characterize the expression patterns of miR-31 and RDX mRNA in 108 glioma and 20 normal brain tissues. The associations of miR-31 and RDX mRNA expressions with clinicopathologic factors and prognosis of glioma patients were also statistically analyzed. RESULTS The expression levels of miR-31 in glioma tissues were significantly lower than those in normal brain tissues (P<0.001), while RDX mRNA was significantly overexpressed in glioma tissues compared with normal brain tissues (P<0.001). There was a negative correlation between miR-31 and RDX mRNA expression in glioma tissues (r=-0.69, P=0.01). Additionally, concomitant miR-31 downregulation and RDX upregulation (miR-31-low/RDX-high) was significantly associated with advanced pathological grade (P=0.001) and low Karnofsky performance score (P=0.01). Moreover, Kaplan-Meier survival and Cox regression analyses showed that the glioma patients with miR-31-low/RDX-high expression had poorest overall survival (P<0.001) and conjoined expression of miR-31-low/RDX-high was an independent prognostic indicator of glioma (P=0.01). Furthermore, subgroup analyses showed that miR-31-low/RDX-high expression was significantly associated with poor overall survival in glioma patients with high pathological grades (for grade III-IV: P<0.001). CONCLUSIONS Our findings have implications concerning the importance of concomitant miR-31 downregulation and RDX upregulation in tumor progression and poor prognosis of patients with gliomas. A combined detection of miR-31/RDX expression may benefit us in predicting clinical outcomes of glioma patients with high pathological grades.

Abstract
BACKGROUND AND OBJECTIVES Bmi1 and EZH2 are involved in tumorigenesis of gliomas. However, clinicopathologic significance of their expression in gliomas is unknown; especially, the prognostic value of combined expression of Bmi1 and EZH2 has not been explored. METHODS Bmi1 and EZH2 expression in human gliomas and nonneoplastic brain tissues was measured by immunohistochemistry. RESULTS Both Bmi1 and EZH2 expressions in glioma tissues were significantly higher than those in corresponding nonneoplastic brain tissues (both P<0.001). Additionally, the upregulations of Bmi1 and EZH2 proteins were both significantly associated with advanced WHO grades (both P<0.001) and low KPS (P=0.008 and 0.01, respectively). Moreover, the overall survival of patients with high Bmi1 protein expression (P=0.006) or high EZH2 protein expression (P=0.01) was obviously lower than those with low expressions. More interestingly, glioma patients with combined overexpression of Bmi1 and EZH2 proteins had the shortest overall survival (P<0.001). Furthermore, multivariate analysis showed that Bmi1n expression (P=0.02), EZH2 expression (P=0.03), and combined expression of Bmi1 and EZH2 (P=0.008), were all independent prognostic factors for overall survival in glioma patients. CONCLUSIONS Our data suggest for the first time that the combination of Bmi1 and EZH2 overexpression may be a highly sensitive marker for the prognosis in glioma patients.

Abstract
AIM: To detect the expression of mitochondrial uncoupling protein 2 (UCP2) in colon cancer and analyze the relation between UCP2 expression and clinical pathological features of colon cancer.
METHODS: Fifteen colon tissue samples and 15 its adjacent tissue samples were obtained from colon cancer patients during surgical interventions. UCP2 expression was detected with immunohistochemical method in 10 normal controls, 10 hyperplastic polyp patients, 20 tubular adenoma patients and 78 colon cancer patients. Patients with rectal cancer were excluded. Quantitative reverse transcription polymerase chain reaction and Western blotting were used to detect UCP2 expressions in colon cancer tissue samples and its adjacent tissue samples. Relation between UCP2 expression and clinical pathological features of colon cancer was also analyzed.
RESULTS: The UCP2 mRNA expression level was four-fold higher in colon cancer tissue samples than in its adjacent tissue samples. The UCP2 protein expression level was three-fold higher in colon cancer tissue samples than in its adjacent normal tissue samples. The UCP2 was mainly expressed in cytoplasm. The UCP2 was not expressed in normal colon mucosa. Strong positive staining for UCP2 with a diffuse distribution pattern was identified throughout the mucosa in colon cancer tissue samples with a positive expression rate of 85.9%. The UCP2 expression level was higher in colon cancer tissue samples at clinical stages III and IV than in those at stage I + II. Univariate analysis showed that the high UCP2 expression level was significantly correlated to colon cancer metastasis (hazard ratio = 4.321, confidence interval = 0.035-0.682, P = 0.046).
CONCLUSION: UCP2 is highly expressed in human colon cancer tissue and may be involved in colon cancer metastasis.
