Impact of circulating miRNA-373 on breast cancer diagnosis through targeting VEGF and cyclin D1 genes.

BACKGROUND: Breast cancer (BC) is the common primary tumor among females. Hence, there is an urgent need to improve the early prediction and diagnosis of BC. For that reason, the object of the current study is to analyze the expression levels of miRNA-373 and its target genes including vascular endothelial growth factor (VEGF) and cyclin D1 in women with BC. RESULTS: Upregulation of miRNA-373 and its target genes was observed in BC patients followed by patients with benign breast lesions compared to downregulation in controls. There was a significant association between the expression level of miRNA-373 and all clinical features. The same associations were observed between its target genes and all clinico-pathological features except hormonal status. The correlation between miRNA-373 and both genes was significant. CONCLUSIONS: Our results prove that miRNA-373, as an oncomir, would be a vital biomarker for BC diagnosis and prognosis by targeting both VEGF and cyclin D1.

NOD-like receptor X1, tumor necrosis factor receptor-associated factor 6 and NF-κB are associated with clinicopathological characteristics in gastric cancer.

Gastric cancer (GC) is a common cancer worldwide and its precise mechanism is largely unknown. The aim of the present study was to evaluate the expression levels of NOD-like receptor X1 (NLRX1), tumor necrosis factor receptor-associated factor 6 (TRAF6) and NF-κB in GC and normal gastric tissue samples to determine the association with the clinicopathological features of GC. GC and adjacent normal gastric tissues from 60 patients with GC were analyzed using immunohistochemistry and western blotting analysis. In addition, the association between NLRX1, TRAF6 and NF-κB expression levels were investigated by Spearman's correlation analysis. The results revealed that NLRX1 protein expression levels were downregulated in the GC tissues compared with the normal gastric tissues (P<0.05). Conversely, TRAF6 and NF-κB protein expression levels were upregulated in the GC tissues compared with the normal gastric tissues (P<0.05). A significant difference was identified between GC patients with high and low expression levels of each protein in the tumor size, vascular invasion, neural invasion, lymph node metastasis, differentiation, gross stage and clinical stage. In addition, a negative correlation was observed between NLRX1 and TRAF6, and NLRX1 and NF-κB expression levels, while a positive correlation was observed between TRAF6 and NF-κB expression levels. In conclusion, NLRX1 expression levels were discovered to be downregulated in GC tissues. The expression levels of NLRX1, TRAF6 and NF-κB were also significantly associated with the clinicopathological characteristics of GC, and the aforementioned results indicated that NLRX1 may be a biomarker in assessing GC.

IgG4-related disease: a contemporary review

Background/aim: Immunoglobulin G4-related disease (IgG4-RD), is an immune-mediated fibroinflammatory condition, which may involve multiple organs and mostly presents with high serum IgG4 levels and specific histopathological characteristics. As IgG4-RD is a relatively new entity the etiology, prevalence and epidemiologic knowledge is quite limited. Although involvement of almost all anatomical regions has been reported, the most commonly affected regions are pancreas, lacrimal glands, salivary glands, retroperitoneum, orbita, lymph nodes, kidney and lungs. Diagnosis is made with combined evaluation of clinical, radiological and histopathological findings. Typical histopathological features include storiform fibrosis, dense lymphoplasmacytic infiltrates and obliterative phlebitis. Its course is typically marked by remission and relapsing attacks and it may lead to fibrosis, destructive lesions in tissues and organ failure unless promptly treated. In the treatment of IgG4-RD, many approaches including surgical resection of tissues, systemic glucocorticoids, steroid-sparing immunosuppressive drugs, and biological agents are employed. Although association is not clear, malignancies are frequently reported in IgG4-RD patients. Therefore, it is prudent to monitor patients for the symptoms of malignant diseases. Conclusion: In this review, recent advances in clinico-pathological characteristics, diagnosis, and treatment of IgG4­RD are discussed.

Very long-term survivors among patients with metastatic soft tissue sarcoma.

BACKGROUND: Metastatic soft tissue sarcomas (STS) are a group of rare and heterogeneous mesenchymal tumors with a poor prognosis. The aim of this study was to evaluate the incidence of long-term survivors and describe their presentation and management in a large cohort of patients with metastatic STS. METHODS: We collected information of patients with metastatic STS managed in Centre Leon Berard between 1985 and 2015 aiming to compare the group of patients alive 5 years after the diagnosis of metastases vs the others. Prognostic factors of patients and tumors characteristics were investigated by logistic regression analysis. For "long-term survivors," we explored therapeutic strategies at metastatic stage. RESULTS: Out of 436 patients enrolled, 39 (9%) were still alive 5 years after diagnostic of metastases with a median survival of 146 months (12 years). This "long-term survivors" group included more female and younger patients, with better performance status, more synovial sarcoma or endometrial stromal sarcoma, more patients with simple genomic sarcomas, lower tumor grade, smaller tumor, and longer disease-free interval. In multivariate analysis, age below 55 at metastatic stage (P = 0.0002) and grade 1 tumor (P < 0.0001) were significantly associated with the "long-term survivors." Their therapeutic management was usually aggressive (intensified or polychemotherapy, repeated local treatment of metastases), leading to 62% of complete response in first-line setting. CONCLUSIONS: Very long-term survivors are observed in metastatic STS. Selection of patients in good condition with less aggressive tumor and administration of intensive treatment may lead to obtain these motivating results in a poor prognosis disease.

ALK gene copy number gains in non-small-cell lung cancer: prognostic impact and clinico-pathological correlations.

BACKGROUND: The correlation between ALK gene copy number gain (ALK-CNG) and prognosis in the context of advanced non-small-cell lung cancer (NSCLC) remains a controversial issue. This study aimed to evaluate the association among ALK-CNG according to Fluorescent In Situ Hybridization (FISH), clinical characteristics and survival in resectable and advanced NSCLC. METHODS: Clinical and pathological data of patients with resectable and advanced NSCLC were retrospectively collected. Tumor tissues were analyzed for ALK-CNG by FISH, and patients were divided in 3 groups/patterns on the basis of ALK signals: disomic [Pattern A], 3-7 signals [Pattern B], >7 signals [Pattern C]. The association between clinical and pathological features and ALK-CNG patterns was evaluated. Disease/progression-free and overall survival (DFS/PFS and OS) were estimated using the Kaplan-Meyer method. RESULTS: A number of 128 (76.6 %) out of the 167 eligible patients were evaluable for ALK-CNG, displaying pattern A, B and C in 71 (42.5 %), 42 (25.1 %) and 15 (9 %) patients, respectively. Gains in ALK-CNG appear to be more frequent in smokers/former smokers than in non-smokers (74.2 % versus 20.4 %, respectively, p = 0.03). Pattern A and C seem more frequently associated with higher T-stage (T3-4), while pattern B appears more represented in lower T-stage (T 1-2) (p = 0.06). No significant differences in survival rate were observed among the above groups. CONCLUSIONS: A high ALK-CNG pattern might be associated with smoking status and theoretically it might mirror genomic instability. The implications for prognosis should be prospectively investigated and validated in larger patients' series. TRIAL REGISTRATION: We confirm that all the study was performed in accordance with relevant guidelines and regulations and that all the protocol (part of a larger project MFAG 2013 N.14282) was approved by the local Ethics Committee of the Azienda Ospedaliera Universitaria Integrata of Verona on November 11st, 2014.

Characteristics of breast cancer in Central China, literature review and comparison with USA.

INTRODUCTION: This work was to analyze characteristics of breast cancer (BC) in Central China, summarize main characteristics in China and compare with USA. METHODS: BC main characteristics from four hospitals in Central China from 2002 to 2012 were collected and analyzed. All the single and large-scale clinical reports covering at least ten years were selected and summarized to calculate the BC characteristics of China. BC Characteristics in USA were selected based on the database from Surveillance, Epidemiology, and End Results (SEER) Program. RESULTS: Age distribution in Central China was normal with one age peak at 45-49 years, displaying differences from USA and Chinese American with two age peaks. BC characteristics in Central China displayed distinct features from USA and Chinese American, including significant younger onset age, lower proportion of patients with stage I, lymph node negative, small tumor size and ER positive. A total ten long-term and large-scale clinical reports were selected for BC characteristics of Mainland China analysis. A total of 53,571 BC patients were enrolled from 1995 to 2012. The main characteristics of BC in Mainland China were similar as that in Central China, but were significant different from developed regions of China (Hong Kong and Taiwan), USA and Chinese American. CONCLUSIONS: BC characteristics in Central China displayed representative patterns of Mainland China, while showed distinct patterns from Chinese patients in other developed areas and USA.

Correlation between long non-coding RNA in tumor tissues and clinico-pathological characteristics of hepatocellular carcinoma / 中华肝胆外科杂志

Objective To evaluate the relationship between long non-coding RNAs (LncRNA) in tumor tissues and clinico-pathological features of hepatocllular carcinoma (HCC).Methods Using hepatocellular carcinoma gene database GSE36376,we conducted a study on eight LncRNAs which are associated with liver diseases and analyzed the correlation between these LncRNAs and HCC clinico-pathological characteristics.We also evaluated the potential effect of LncRNAs on HCC development.Results H19 was overexpressed in non-tumorous tissues of HCC (P ＜ 0.05),while MEG3,HOXA13,KCNQ1OT1 were all upregulated in tumorous tissues (all P ＜ 0.05).HULC level in HCC tumorous tissues was negatively correlated with AJCC staging,BCLC staging and tumor size (all P ＜ 0.05).UCA1 was positively correlated with BCLC staging (r =0.135,P ＜ 0.05).Univariate analysis and multivariate logistic analyses showed that UCA1 was a risk factor of intrahepatic metastasis of HCC (OR =6.054,95％ CI =1.429 ～ 25.642,P ＜ 0.05); in contrast,HULC overexpression in tumorous tissues played a positive role in HCC tumor size (OR=0.805,95％CI=0.678 ～0.956,P＜0.05).Conclusion HULC in tumorous tissues suppressed HCC proliferation,while UCA1 was a risk factor of HCC aggressiveness.

Relationship between family history of breast cancer and clinicopathological features in Moroccan patients.

BACKGROUND: Breast cancer is the most common cancer affecting women all over the world. In addition to hormonal and environmental causes, family history is emerging as an important risk factor in the etiology of this disease. The aim of the present study is thus to compare the clinico-pathological features of familial and sporadic breast cancer in Moroccan patients. METHODS: A comparative retrospective cohort study was conducted on 570 women with familial and sporadic breast cancer who were diagnosed and treated in the Oncology Center of Ibn Rochd University Hospital in 2009. Data on breast cancer risk factors and clinico-pathological characteristics of the tumors were extracted from patients' medical records. RESULTS: Familial cases represented 18.4% of breast cancer patients. The age of onset appears to be earlier in familial breast cancers (P=0.0024). There were no significant differences between familial and sporadic groups according to histological type, tumor size and estrogen receptor status. However, Scarff-Bloom-Richardson grade III was found in 43.8% of familial cases vs 26.7% of sporadic cases (P=0.0127) and the lymph node involvement was observed in 72.4% of familial cases vs 58.9% in sporadic cases (P=0.0213). Moreover, familial breast cancer patients present especially progesterone receptor-negative tumors (P=0.0380). CONCLUSIONS: Our initial significant findings show that familial breast cancer seems to affect young women and tends to present high Scarff-Bloom-Richardson grade tumors with lymph node involvement and absence of progesterone receptors. These preliminary results may be useful as clinical marker to identify familial breast cancer allowing the development of careful follow-up for this patients subtype.

Clinicopathological Characteristics of Colorectal Cancer according to Microsatellite Instability

BACKGROUND/AIMS: Microsatellite instability (MSI) is associated with mutations in the DNA mismatch repair system and accounts for 10-15% of all cases of sporadic colorectal cancer (CRC). However, the characteristics and role of MSI as a marker for predicting the prognosis and therapeutic effect on CRC remain unclear. METHODS: Between June 2003 and December 2007, 259 patients (males, 159 [61%]; age, 63 [+/-11] years) who underwent surgery for CRC were retrospectively enrolled. The clinicopathologic characteristics of patients with high-frequency MSI (MSI-H) CRC were reviewed and compared to patients with low-frequency MSI or microsatellite stable CRC. The patient characteristics and MSI-related data were recorded for the following variables: gender, age, clinicopathologic findings, chemotherapy response, recurrence, and survival. RESULTS: MSI-H CRC was diagnosed in 30 patients (12%), low-frequency MSI CRC was diagnosed in 10 patients (4%), and microsatellite stable CRC in was diagnosed in 219 patients (84%). The MSI-H group exhibited the following characteristics: large size, right colon location, positive response to chemotherapy, low recurrence, longer survival, less neural invasion, poor differentiation, diffuse lymphoid reaction, and mucin pool formation. However, in the chemotherapy group (n=180), MSI-H was not a marker of longer survival. Based on Cox-regression analysis, stage IV CRC (OR=6.66; 95% CI, 2.24-53.00), MSI-H (OR=0.17; 95% CI, 0.04-0.73), and a positive response to chemotherapy (OR=0.02; 95% CI, 0.01-0.11) were related to mortality. CONCLUSIONS: MSI-H CRC had less neural invasion and diffuse lymphoid reaction. Further studies regarding the relationship between those pathologic findings and survival are needed.
