Objectives: Tobacco and alcohol are the main etiological factors common to laryngeal cancers. However, the Human Papilloma Virus (HPV) constitutes an alternative risk factor according to several studies. In Tunisia, despite the annual increasing incidence of laryngeal squamous cell carcinoma (LSCC), the prevalence and prognostic significance of HPV have never been explored. In this study, we sought to highlight HPV DNA in 70 biopsies of laryngeal cancer, and to analyze the status of HPV infection in association with p53, p16, survivin, and IGF-1R expressions. Methods: HPV high risk (HPV HR) DNA was detected in tumors by in situ hybridization. However, the expression of p53, p16, survivin and IGF-1R were stained by immunohistochemistry test. The correlations of HPV status with clinicopathological parameters, overall survival, disease-free survival and proteins expressions were statistically evaluated. Results: HPV HR DNA was detected in 39 out of 70 (55.71%) laryngeal tumors. HPV+ patients have a better overall survival ( P = .081) and long disease-free-survival ( P = .016) with a low rate of recurrence ( P = .006) than HPV– patients. No significant correlations were found between HPV HR status and clinicopathological parameters (all P > .005). Moreover, HPV+ tumors were not associated with expression of p53, p16 and survivin. However, HPV HR status correlates with weak to moderate IGF-1R expression ( P = .043). Conclusion: The substantial detection of HPV HR in LSCC tumors suggest that this virus plays an important part in laryngeal cancer in Tunisia. It is a good prognostic factor. In addition, HPV infection could act to block the pathway of IGF-1R expression.

CONTEXT: Patients receiving adjuvant chemotherapy for breast cancer have a tendency to gain weight. This tendency has determining factors not completely defined and an unknown prognostic impact. OBJECTIVE: To evaluate weight change during chemotherapy for breast cancer in a defined population and to identify its predisposing factors and possible prognostic significance. DESIGN: Observational, retrospective cohort study. SETTING: Private clinical oncology service. PARTICIPANTS: 106 consecutive patients with breast cancer treated between June 1994 and April 2000, who received neoadjuvant (n = 8), adjuvant (n = 74) or palliative (n = 24) chemotherapy. INTERVETION: Review of medical records and gathering of clinical information, including patients’ body weights before treatment and at follow-up reviews. MAIN MEASUREMENTS: Body weight change, expressed as percentage of body weight per month in treatment; role of clinical data in weight change; and influence of weight change in overall survival and disease-free survival. RESULTS: There was a mean increase of 0.50 ± 1.42% (p = 0.21) of body weight per month of treatment. We noted a negative correlation between metastatic disease and weight gain (r = -0.447, p < 0.0001). In the adjuvant and neoadjuvant therapy groups there was a mean weight gain of 0.91 ± 1.19 % (p < 0.00001) per month, whereas in the metastatic (palliative) group, we observed a mean loss of 0.52 ± 1.21% (p = 0.11) of body weight per month during the treatment. We did not observe any statistically significant correlation between weight changes and disease-free survival or overall survival. CONCLUSIONS: Women with breast cancer undergoing adjuvant or neoadjuvant chemotherapy gain weight, whereas metastatic cancer patients will probably lose weight during palliative chemotherapy. Further studies are needed in order to evaluate the prognostic significance of weight changes during chemotherapy.

Objective 1. To determine whether p53 protein expression is prognostic indicator of patient survival. 2. Learn its correlation with habits and histological variables of the tumor in Pakistani patients. Methods A retrospective case series of 140 patients with primary oral squamous cell carcinoma at a tertiary care setting during the period of January 1991 to Dec 2004. p53 protein overexpression was investigated by means of immunohistochemistry. Results of p53 overexpression were evaluated in relation to different clinicopathological parameters and survival. Overall survival and disease-free survival were measured. Event time distributions for these end points were estimated by use of the method of Kaplan and Meier and compared by use of the log-rank statistic. Factors associated with p53 status were selected on cross-tabulations and logistic regression. Cross-tabulations were analyzed by use of the chi-square test or Fisher's exact test, where appropriate. Results were summarized as odds ratio (OR) with corresponding 95% Confidence Interval. Results Overexpression of p53 protein was observed in 75 patients (54%). Patients with p53 negative tumors had improved overall survival (OS) when compared with patients with p53 positive tumors (p=0.036). The p53 overexpression did not correlate with disease-free survival (DFS) (p=0.126), histological differentiation (p=0.611) and patients’ habits (p=0.894) In univariate analysis, AJCC stage, nodal status, tumor size and histological grade were significantly associated with shortened OS and DFS. Conclusions Our study supports that patients with p53 overexpression had a significantly poor overall survival compared to p53 negative patients. However, p53 overexpression was not associated with patients disease-free survival.

AbstractPrognostic significance of family with sequence similarity 83, member D (FAM83D) in hepatocellular carcinoma (HCC) patients has not been well-investigated using Gene Expression Omnibus (GEO) series and TCGA database, we compared FAM83D expression levels between tumor and adjacent tissues, and correlated FAM83D in tumors with outcomes and clinico-pathological features in HCC patients. Validated in GSE33006, GSE45436, GSE84402 and TCGA, FAM83D was significantly overexpressed in tumor tissues than that in adjacent tissues (all P<0.01). FAM83D up-regulation was significantly associated with worse overall survival (OS) and disease-free survival (DFS) in HCC patients (Log rank P=0.00583 and P=4.178E-04, respectively). Cox analysis revealed that FAM83D high expression was significantly associated with OS in HCC patients [hazard ratio (HR) = 1.44, 95% confidence interval (CI) = 1.005–2.063, P=0.047]. Additionally, patients deceased or recurred/progressed had significantly higher FAM83D mRNA levels than those living or disease-free (P=0.0011 and P=0.0238, respectively). FAM83D high expression group had significantly more male patients and advanced American Joint Committee on Cancer (AJCC) stage cases (P=0.048 and P=0.047, respectively). FAM83D mRNA were significantly overexpressed in male (P=0.0193). Compared with patients with AJCC stage I, those with AJCC stage II and stage III–IV had significantly higher FAM83D mRNA levels (P = 0.0346 and P=0.0045, respectively). In conclusion, overexpressed in tumors, FAM83D is associated with gender, AJCC stage, tumor recurrence and survival in HCC.

AbstractBackground:Metastasis to regional lymph nodes via lymphatic microvessels plays a key role in cancer progression, and is an important prognostic factor in many cancers. Recent evidence suggests that tumour lymphangiogenesis promotes lymphatic metastasis.Aims:To investigate whether tumour lymphatic microvessel density correlates with clinicopathological factors and serves as a prognostic indicator of supraglottic laryngeal carcinoma progression.Methods:The lymphatics of 84 supraglottic laryngeal carcinoma cases were investigated by immunohistochemical staining for podoplanin (also termed D2-40). The relationships between (intra- and peritumoural) lymphatic microvessel density, clinicopathological parameters and clinical prognosis were analysed.Results:There was a significant relationship between high intratumoural lymphatic microvessel density and aggressive tumour node stage (p < 0.0001), distant metastasis (p = 0.037) and poor prognosis (p = 0.011), and between high peritumoural lymphatic microvessel density and node stage (p = 0.004) and poor prognosis (p = 0.029). Patients with high lymphatic microvessel density also had significantly worse disease-free survival (p = 0.003) and overall survival (p = 0.005). Intratumoural lymphatic microvessel density was found to be an independent prognostic factor for overall survival (p = 0.008) and disease-free survival (p = 0.005) (multivariate analysis).Conclusion:Lymphatic microvessel density (detected by podoplanin immunohistochemistry), especially intratumoural density, may be an independent predictor of lymphatic tumour spread and survival in supraglottic laryngeal carcinoma patients, and may be useful to guide decisions regarding additional surgery.

Background Recently, microRNA-221 has been found to be abnormally expressed in hepatocellular carcinoma; however, its clinical value has not been summarised. This meta-analysis aimed to assess the prognostic significance of miR-221 in hepatocellular carcinoma. Material and Methods PubMed, Science Direct, Web of Science, Scopus, Ovid MEDLINE, EMbase, Google Scholar, the Cochrane Library, CNKI, CBM, VIP and Wanfang databases were searched for eligible articles. The endpoints included overall survival, progression-free survival, recurrence-free survival, metastasis-free survival, disease-free survival. Hazard ratios with 95% confidence intervals were used to explore the relationship between miR-221 expression and clinical survival results of liver cancer patients. Subgroup analysis and sensitivity analysis were performed. Begg’s test and Egger’s test were conducted to evaluate publication bias. Results A total of nine studies including 607 patients were recruited for this meta-analysis. The pooled hazard ratios displayed that high miR-221 expression was remarkably associated with poorer overall survival (hazard ratio = 1.91, 95% confidence interval: 1.53–2.38, p ＜ 0.01) and unfavourable progression-free survival/recurrence-free survival/metastasis-free survival/disease-free survival (hazard ratio = 2.02, 95% confidence interval: 1.58–2.57, p ＜ 0.01). The results of Begg’s test and Egger’s test did not exhibit obvious publication bias. Conclusions High expression of miR-221 can predict poor outcome of hepatocellular carcinoma. miR-221 can be used as a promising prognostic biomarker of hepatocellular carcinoma.

AbstractObjective:This study assessed the relationship between vascular endothelial growth factor expression and the laryngeal cancer prognosis.Methods:Systematic computerised searches of PubMed were performed up to 31 January 2015. Prognostic endpoints were overall survival and disease-free survival. The pooled hazard ratios for overall survival and disease-free survival were also calculated.Results:Seven studies containing 975 patients were included. The pooled hazard ratio was 1.703 (95 per cent confidence interval, 1.373 to 2.112; z score = 4.85, p = 0.000) for overall survival and was 1.918 (95 per cent confidence interval, 1.410 to 2.609; z score = 4.15, p = 0.000) for disease-free survival. No significant publication bias was found. A sensitivity analysis showed that the results were robust. Power analyses also showed there was enough power to detect the calculated hazard ratios.Conclusion:The study found that vascular endothelial growth factor overexpression predicted a worse prognosis for laryngeal cancer patients. This supports a strategy of targeted therapy by blocking the vascular endothelial growth factor receptor.

Background Although many studies have investigated the prognostic effect of thymidylate synthase (TS) in colorectal cancer, no consensus has been reached. The aim of this meta-analysis was to obtain a more precise estimate of the prognostic significance of TS expression in localized cancers treated by curative resection and adjuvant chemotherapy. Materials and method Seventeen eligible studies reporting survival in 2,893 patients stratified by TS expression were pooled using a fixed- or random-effects model. The main outcome measure was hazard ratio (HR). Results The overall HR for overall survival was 1.01 (95% CI 0.74–1.39, p=0.947), with an I2 of 64.4%. The total HR for disease-free survival was 1.36 (95% CI 0.97–1.89, p=0.072), with an I2 of 75.8%. In the TS protein-tested subgroup, the total HR for disease-free survival was 1.72 (95% CI 1.02–2.89, p=0.042), with an I2 of 81.3%. Conclusion Our meta-analysis showed that, in the adjuvant setting, TS expression does not predict a poorer disease-free survival or a worse overall survival. Therefore, we believe that it is inappropriate to regard TS expression as a prognostic factor for patients with stage II and stage III colorectal cancer treated by surgery and adjuvant chemotherapy.

Aim: To explore the prognostic significance of Syt-7 in hepatocellular carcinoma (HCC) and the potential mechanisms. Methods: Immunohistochemistry was used to examine the expression of Syt-7. Overall survival and disease-free survival were compared between Syt-7 positive and negative groups. The effects of Syt-7 knockdown on BEL-7404 cells were further evaluated. Results: Syt-7 expression was significantly higher in HCC tumorous tissues compared with paracancerous tissues. Syt-7 was closely associated with α-fetoprotein tumor size, vascular invasion, tumor node metastasis stage and tumor differentiation. Syt-7 was an independent risk factor for overall survival and disease-free survival. Additionally, Syt-7 knockdown inhibited proliferation and colony formation and induced cell cycle arrest in HCC cells. Conclusion: Syt-7 overexpression forecasts unfavorable prognosis and promotes cell proliferation in HCC.

Background: Inflammation plays an important role in tumor progression. Predicting survival is remarkably difficult in patients with gastric cancer receiving neoadjuvant chemotherapy. The aim of the present study is to investigate the potential prognostic significance of the platelet-to-lymphocyte ratio in patients with gastric cancer receiving S-1 plus oxaliplatin or oxaliplatin and capecitabine regimen. Methods: Ninety-one patients with gastric cancer treated with neoadjuvant chemotherapy were enrolled in this study and then underwent operation. The optimal cutoff value was calculated using receiver-operating characteristic curve analyses. The optimal cutoff value of platelet-to-lymphocyte ratio was divided into low platelet-to-lymphocyte ratio <162 group and high platelet-to-lymphocyte ratio ≥162 group. Kaplan-Meier method and log-rank test were used to analyze the survival curves. The independent prognostic factors and prognostic value of the platelet-to-lymphocyte ratio were assessed by univariate and multivariate Cox proportional hazards regression model. The toxicity was evaluated according to the National Cancer Institute Common Toxicity Criteria. Results: Kaplan-Meier analyses revealed that patients with low platelet-to-lymphocyte ratio correlated remarkably with better mean disease-free survival and mean overall survival than those with high platelet-to-lymphocyte ratio (mean disease-free survival 47.33 and 33.62 months, respectively; mean overall survival 51.21 and 36.80 months, respectively). The results demonstrated that platelet-to-lymphocyte ratio had prognostic significance using the cutoff value of 162 on disease-free survival and overall survival, and the mean disease-free survival and overall survival time for patients with low platelet-to-lymphocyte ratio were longer than those with high platelet-to-lymphocyte ratio. Meanwhile, patients with gastric cancer who had lower platelet-to-lymphocyte ratio had longer 1-, 3-, and 5-year rates of disease-free survival and overall survival. Moreover, patients with low platelet-to-lymphocyte ratio had longer mean disease-free survival and overall survival than those with high platelet-to-lymphocyte ratio in receiving S-1 plus oxaliplatin or oxaliplatin and capecitabine regimen. Conclusions: The preoperative platelet-to-lymphocyte ratio may be a promising and convenient prognostic biomarker for patients gastric cancer receiving S-1 plus oxaliplatin or oxaliplatin and capecitabine regimen neoadjuvant chemotherapy. It may be useful to help the doctors identify the high-risk patients for taking efficient treatment strategy decisions.

The double-stranded RNA-binding protein TARBP2 has been suggested to act as an upstream regulator of breast cancer metastasis by destabilizing transcripts of the possible metastasis suppressors amyloid precursor protein (APP) and ZNF395. We examined this hypothesis by immunostaining of TARBP2, APP, and ZNF395 in 200 breast cancer specimens using tissue microarrays and analyzed the relationships between expression levels and clinicopathological parameters and prognosis. Increased TARBP2 overexpression was associated with shorter overall survival and disease-free survival, and increased but not reduced APP expression correlated with lower overall survival and disease-free survival. ZNF395 expression levels had no prognostic value, but reduced expression correlated with reduced lymph node metastasis. There was no significant relationship between TARBP2 overexpression and reduced APP and/or ZNF395 expression. Patients with tumors with higher TARBP2 or APP expression had unfavorable prognoses. Although reduced ZNF395 expression was significantly related to reduced lymph node metastasis, further studies are needed to clarify the role of TARBP2/APP/ZNF395 in breast cancer.
