Elevated platelet count is a strong predictor of poor prognosis in stage I non-small cell lung cancer patients

Stage I non-small cell lung cancer (NSCLC) show a highly variable biological behavior which cannot be accurately predicted by the current available prognostic markers. Platelet plays a significant role in cancer cell growth, progression and metastasis. This study aimed to investigate whether preoperative platelet count correlate with clinical prognosis in localized NSCLC. A retrospective clinical analysis was designed for a total of 234 stage I NSCLC patients in our hospital between October 2006 and December 2009. Pre-operative platelet count was measured. The association of platelet count with clinical pathological factors and patient outcome was evaluated. A significant correlation was detected between platelet count and tumor cell differentiation and T stage. Patients with elevated platelet count had an elevated risk of disease progression and death compared to patients with normal platelet count. The hazard ratio was 5.314 (95% confidence interval [CI] 2.750–10.269) for disease progression and 3.139 (95% CI 1.227–8.034) for death. The trend linking increasing platelet count with risk was also statistically significant for both the outcomes (p?<?0.05). These finding demonstrate that preoperative platelet count is a useful predictor of high risk progression and poor prognosis in stage I NSCLC patients.

Prognostic value of FGFR1 gene copy number in patients with non-small cell lung cancer: a meta-analysis

Background

A number of studies have investigated the relationship between fibroblast growth factor receptor1 (FGFR1) gene copy number and survival in non-small cell lung cancer (NSCLC) patients. However, conclusions reported by different parties seem to be inconsistent, especially regarding the differences among different histopathologic subtypes. To derive a more precise estimate of the prognostic significance of FGFR1 gene copy number, we have reviewed published studies and carried out a meta-analysis.

Methods

The meta-analysis was conducted in accordance with PRISMA guidelines. The required data for estimation of individual hazard ratios (HRs) for survival were extracted from the publications and an overall HR was calculated.

Results

We identified 6 eligible studies, all dealing with NSCLC. The global quality score ranged 32.5-80%, with a median of 53.33%. For FGFR1 amplification in three studies including differed according to histological type, the overall RR was 0.86 which 95% confidence interval (CI) was 0.75 to 0.99 and P value was 0.048. Combined HR for the six evaluable studies was 1.17 (95% CI: 0.95 to 1.43). In the subgroup of squamous cell lung cancer (SQCC), the combined HR was 1.24 (95% CI: 0.89 to 1.73). For the Asian populations’ studies, the combined HR was 1.67 (95% CI: 1.1 to 2.52).

Conclusions

FGFR1 amplification significantly was more frequent in SQCC. FGFR1 was not associated with poorer survival in patients with NSCLC. Furthermore studies will be needed in terms of survival implications.     

Lung cancer: Preoperative pulmonary evaluation of the lung resection candidate

Lung resection provides the best chance of cure for individuals with early stage non-small cell lung cancer. Naturally, lung resection will lead to a decrease in lung function. The population that develops lung cancer often has concomitant lung disease and a reduced ability to tolerate further losses in lung function. The goal of the preoperative pulmonary assessment of individuals with resectable lung cancer is to identify those individuals whose short- and long-term morbidity and mortality would be unacceptably high if surgical resection were to occur. Pulmonary function measures such as the forced expiratory volume in 1 second and the diffusing capacity for carbon monoxide are useful predictors of postoperative outcome. In situations in which lung function is not normal, the prediction of postoperative lung function from preoperative results and the assessment of exercise capacity can be performed to further clarify risks. Published guidelines help to direct the order of testing, permitting us to offer resection to as many patients as possible.

目的探讨非小细胞肺癌患者(NSCLC)血浆中CR-1的表达水平与患者临床病理特征之间的关系,及其对肺癌预后的判断价值。方法收集35例正常人血浆,40例良性肺部疾病患者和102例NSCLC患者血浆,用酶联免疫吸附法(ELISA)检测血浆CR-1表达水平。结果NSCLC患者血浆CR-1水平远高于健康对照组(P<0.05),良性肺部疾病患者血浆CR-1浓度虽也有一定的升高,但较之肺癌组低,二者间差异有显著性(P<0.05)。肺癌患者血浆CR-1水平与淋巴结转移状态和临床分期有关(P<0.01)。血浆CR-1与患者生存期密切相关,生存>12个月患者血浆CR-1明显低于<12个月者(P<0.01)。结论血浆CR-1与NSCLC的病程进展及生存期相关,是一种有价值的预后判断指标。     

Expression of paired basic amino acid-cleaving enzyme 4 (PACE4) correlated with prognosis in non-small cell lung cancer (NSCLC) patients

Background

Paired basic amino acid-cleaving enzyme 4 (PACE4) was shown to enhance tumor cells proliferation and invasive. This study provides the first investigation of PACE4 expression in non-small cell lung cancer (NSCLC) and the correlation with clinicopathologic features, prognostic indicators of 172 cases.

Methods

Quantitative real-time PCR (RT-PCR) and immunofluorescence (IF) were applied to detect PACE4 expression in NSCLC and 16HBE cell lines, then 172 consecutive NSCLC and 15 normal lung tissues were studied through immunohistochemistry (IHC). The association between PACE4 expression and clinicopathological parameters was evaluated. Kaplan-Meier survival analysis and Cox proportional hazards models were used to estimate the effect of PACE4 expression on survival.

Results

PACE4 expression in NSCLC were significantly higher than normal lung cell and tissues (P<0.05). PACE4 had cytoplasmic expression and was observed in 111 of the 172 (64.5%) NSCLC patients. Clinicopathologically, PACE4 expression was significantly associated with lymph node metastasis (N stage) (P=0.007), and clinical stage (P=0.024). Multivariable analysis confirmed that PACE4 expression increased the hazard of death after adjusting for other clinicopathological factors [hazards ratio (HR): 1.584; 95% confidence interval (CI): 1.167-2.151; P<0.001]. Overall survival (OS) was significantly prolonged in PACE4 negative group when compared with PACE4 positive group (5-year survival rates, 23.1% vs. 54.5%, log-rank test, χ²=17.717, P<0.001), as was disease-free survival (DFS) (5-year survival rates, 23.4% vs. 55.4%, log-rank test, χ²=20.486, P<0.001).

Conclusions

Our results suggest that positive expression of PACE4 is an independent factor for NSCLC patients and it might serve as a potential prognostic biomarker for patients with NSCLC.

A high density of PD-L1-expressing immune cells is significantly correlated with favorable disease free survival in nonmetastatic colorectal cancer

The impact of immune cells (ICs) expressing various markers remains poorly understood in nonmetastatic colorectal cancer patients who have undergone colectomy. Here, we aimed to clarify the correlation between IC density and clinical parameters and survival.Programmed death protein-1 (PD-1), programmed cell death protein ligand-1 (PD-L1), clusters of differentiation (CD)-3, CD-8, and CD45RO immunostaining was performed for 421 patients using tissue microarray and automatic counting. Tumor stroma area immune density was assessed in comparison to clinical histological factors and surgical outcomes.High-density CD-8 expression was significantly associated with current smoking habits or a smoking history (P = .006). High-density of PD-1 expression was correlated with Lynch syndrome patients (P < .001) and with patients who did not consume alcohol (P = .034). A significant decrease in CR45RO expression density was associated with aging (P = .002 and r = –0.014), and high-density CD-3, CD-8, and PD-1 expression was significantly associated with right colon tumor location (P < .001). High CD-3 and PD-L1 expression was significantly associated with early tumor T-staging (P = .018 and P = .002). High-density PD-1 expression was significantly correlated with mucinous type adenocarcinoma (P = .027) and poor differentiation (P < .001). For treatment outcomes, multivariate analysis confirmed that patients exhibiting high-density PD-L1 expression possessed significantly longer disease free survival (adjusted hazard ratio: 0.752, 95% confidence interval [CI]: 0.61–0.92, P = .006) and overall survival (adjusted hazard ratio: 0.872, 95% CI: 0.75–1.91, P = .064)Significantly varied density in IC subsets was related to distinct demographic or clinic-histological factors. The presence of high-density PD-L1-expressing ICs is an independent favorable prognostic factor for disease free survival and overall survival among stage I to III colorectal cancer patients.     

A case of relapsing polychondritis associated with auricular cartilage infiltration of immunoglobulin G4-positive plasma cells and lung cancer

Abstract

A 79-year-old man was diagnosed with relapsing polychondritis, from symptoms of bilateral auricular deformity and pigmentation, polyarthralgia, and audiovestibular damage, and from histological examination of the left auricular cartilage. The left auricular cartilage biopsy specimen revealed cartilage destruction with infiltration of plasmacytes expressing IgG4. This case suggests that IgG4 may be involved in the pathogenesis and etiology of relapsing polychondritis.

Myofibrillogenesis regulator-1 overexpression is associated with poor prognosis of gastric cancer patients

AIM: To investigate the expression of myofibrillogenesis regulator-1 (MR-1) in relation to clinicopathological parameters and postoperative survival in a group of Chinese patients with gastric cancer. METHODS: In our previous study of human wholegenome gene expression profiling, the differentially expressed genes were detected in the gastric cancer and its adjacent noncancerous mucosa. We found that MR-1 was associated with the location and differentiation of tumors. In this study, MR-1 protein expression was determined by immunohistochemistry in specimens of primary cancer and the adjacent noncancerous tissues from gastric cancer patients. A set of real-time quantitative polymerase chain reaction assays based on the Universal ProbeLibrary-a collection of 165 presynthesized, fluorescence-labeled locked nucleic acid hydrolysis probes-was designed specifically to detect the expression of MR-1 mRNA. The correlation was analyzed between the expression of MR-1 and other tumor characteristics which may influence the prognosis of gastric cancer patients. A retrospective cohort study on the prognosis was carried out and clinical data were collected from medical records. RESULTS: MR-1 mRNA and protein could be detected in gastric cancer tissues as well as in matched noncancerous tissues. MR-1 was up-regulated at both mRNA (5.459 ± 0.639 vs 1.233 ± 0.238, P 0.001) and protein levels (34.2% vs 13.2%, P = 0.003) in gastric cancer tissues. Correlation analysis demonstrated that high expression of MR-1 in gastric cancer was significantly correlated with clinical stage (P = 0.034). Kaplan-Meier analysis showed that the postoperative survival of the MR-1 positive group tended to be poorer than that of the MR-1 negative group, and the difference was statistically significant (P = 0.002). Among all the patients with stageⅠ-Ⅳ carcinoma, the 5-year survival rates of MR-1 positive and negative groups were 50.40% and 12.70%, respectively, with respective median survival times of 64.27 mo (95%CI: 13.41-115.13) and 16.77 mo (95%CI: 8.80-24.74). Univariate and multivariate analyses were performed to compare the impact of MR-1 expression and other clinicopathological parameters on prognosis. In a univariate analysis on all 70 specimens, 6 factors were found to be significantly associated with the overall survival statistically: including MR-1 expression, depth of invasion, distant metastasis, lymph node metastasis, vascular invasion and the tumor node metastasis (TNM) stage based on the 7th edition of the International Union against Cancer TNM classification. To avoid the influence caused by univariate analysis, the expressions of MR-1 as well as other parameters were examined in multivariate Cox analysis. Clinicopathological variables that might affect the prognosis of gastric cancer patients were analyzed by Cox regression analysis, which showed that MR-1 expression and TNM stage were independent predictors of postoperative survival. The best mathematical multivariate Cox regression model consisted of two factors: MR-1 expression and TNM stage. Our results indicated that MR-1 protein could act as an independent marker for patient overall survival [Hazard ratio (HR): 2.215, P = 0.043]. CONCLUSION: MR-1 is an important variable that can be used to evaluate the outcome, prognosis and targeted therapy of gastric cancer patients.     

Clinicopathological and prognostic significance of programmed cell death ligand1 (PD-L1) expression in patients with non-small cell lung cancer: a meta-analysis

Objective

Programmed cell death 1 (PD-1) and one of its ligands, PD-L1, are key immune checkpoint proteins. Evidences showed PD-L1 is an emerging biomarker for immunotherapy by anti-PD-1 and anti-PD-L1 antibody in non-small cell lung cancer (NSCLC). To investigate the association of PD-L1 protein expression with clinicopathological features and its impact on survival outcome, we conducted a meta-analysis.

Methods

A comprehensive literature search of electronic databases (up to July 10, 2014) was performed. Correlation between PD-L1 expression and clinicopathological features and overall survival (OS) was analyzed by synthesizing the qualified data. Publication biases were examined.

Results

A total of 1,550 NSCLC patients from 9 studies were included. The pooled odds ratios (ORs) indicated high PD-L1 expression was associated with poor tumor differentiation [OR =0.53, 95% confidence interval (CI): 0.39-0.72, P<0.0001]. Whereas, none of other clinicopathological characteristics [gender, smoking status, histological type, invasive depth of tumor, status of lymph node metastasis and tumor node metastasis (TNM) stage] were correlated with PD-L1 expression in current analysis. The combined hazard ratio (HR) for OS showed high expression of PD-L1 impaired the OS in NSCLC (HR_{positive/negative} =1.47, 95% CI: 1.19-1.83, P=0.0004).

Conclusions

Our meta-analysis indicated PD-L1 protein expression in NSCLC was not associated with common clinicopathological characteristics, except tumor differentiation. It was a poor prognostic biomarker for NSCLC. Further research should be performed to investigate the precise clinicopathological and prognostic significance of PD-L1 in NSCLC under uniform testing standard.
