Overexpression of miR-222 has been found in several types of cancers; however, the expression of miR-222 in non-small cell lung cancer (NSCLC) and its prognostic values are unclear. This study aimed to investigate whether the miR-222 expression level is related to clinicopathological factors and prognosis of NSCLC. Through a prospective study, 100 pairs of NSCLC tissues and adjacent normal tissues were examined by quantitative reverse-transcription polymerase chain reaction. The correlation between miR-222 expression and clinicopathological features was analyzed, and the significance of miR-222 as a prognostic factor and its relationship with survival were determined. Results showed that the expression levels of miR-222 were significantly elevated in the NSCLC tissue compared with that in adjacent normal tissue. In addition, Cox’s proportional hazards model analysis confirmed that miR-222 high expression level was an independent predictor of poor prognosis. In conclusion, miR-222 overexpression is involved in the poor prognosis of NSCLC and can be used as a biomarker for selection of cases requiring especial attention.

e18504 Background: To evaluate the efficacy and safety of irinotecan in combination with platinum against refractory or relapsed small cell lung cancer. Methods: In this retrospective study, we analyzed the data of 1,140 patients who diagnosed small cell lung cancer at our hospital between 2009 and 2012. Of all the patients, 34 were treated with irinotecan and nedaplatin (irinotecan 60mg/m2 on days 1,8 nedaplatin 85mg/m2 day 1,every 3 weeks), and 20 patients were treated with irinotecan and cisplatin (irinotecan 60mg/m2 on days 1,8 cisplatin 75mg/m2day 1,every 3 weeks ) as the second line treatment. Prognostic factors of overall survival (OS) were estimated by Kaplan-Meier and Cox's Regression-proportional hazards model. Results: Of 54 eligible patients, median progression free survival (PFS) was 21weeks, and median OS was 58 weeks. Median PFS was 23 weeks for irinotecan plus nedaplatin and 19 weeks for irinotecan plus cisplatin (P=0.410). Median OS was 62 weeks and 58 weeks, respectively (P=0.714).The response rate (RR) was 29% and 33.3%, respectively (HR 0.818,95%CI 0.234to2.855; P=0.753). In multivariate analysis, younger age, extensive stage while diagnosed, brain metastasis, treated with 3 cycles of irinotecan in combination with platinum or less, and PS≥1 were all associated with a statistically significant increase in the mortality harzard. Toxicity profile was slightly different for each of the arms: hematologic toxicity was higher with nedaplatin, and diarrhea was higher with cisplatin. Conclusions: Irinotecan plus platinum is effective and tolerable for refractory and relapsed small cell lung cancer. [Table: see text]

Background/Aim: We conducted a retrospective analysis of the survival durations of 25 patients diagnosed as having non-squamous cell non-small cell lung cancer with negative or low tumor programmed death-ligand 1 (PD-L1) expression treated with immune checkpoint inhibitor (ICI) monotherapy. Patients and Methods: The progression-free (PFS) and overall (OS) survival were calculated from the initiation of ICI monotherapy. The association between the patient characteristics and the PFS was analyzed using Cox proportional hazards model. Results: The median PFS was 2.6 months, and the 12-month PFS rate was 9.3%. The median OS was 5.5 months, and the 12-month OS rate was 39.8%. A Cox proportional hazards model identified the neutrophil/lymphocyte ratio and presence of liver metastasis as being significantly associated with PFS. Conclusion: Our findings suggest that a subset of patients with non-squamous cell non-small cell lung cancer who show negative or low tumor PD-L1 expression could benefit from ICI monotherapy.

AbstractBackgroundThe expression and significance of CD276 in non-small cell lung cancer (NSCLC) was explored.MethodThe BioGPS database was used to analyze the expression level of CD276 in normal tissues. Studies on the expression of CD276 in NSCLC patients using the Oncomine database. The prognostic roles of CD276 in NSCLC was studied using the Kaplan-Meier plotter database.ResultThe BioGPS database showed CD276 expression in all the human normal tissues. Compared with normal lung tissue, CD276 gene highly expressed in NSCLC tissue at mRNA level (P<0.05). The expression level of CD276 gene was negatively correlated with overall survival (OS) of NSCLC patients. Subgroup analysis showed that CD276 expression level had a significant effect on OS of patients with lung adenocarcinoma, while in squamous cell carcinoma its expression level had no significant effect on OS.ConclusionAccording to the information mined from the tumor gene database, CD276 mRNA was found highly expressed in NSCLC tissue and the expression of CD276 has a significant impact on survival of NSCLC patients, which provides an important theoretical basis for further study of the role of CD276 in the occurrence and development of NSCLC.

The expression level of estrogen receptors (ERα and ERβ) in surgical tumor biopsy specimens from 167 patients with non-small cell lung cancer (NSCLC) was quantified by flow cytometry-based immunofluorescence analysis. ERα and ERβ expression was revealed in all the tumor samples investigated. The level of ERα expression in the tumors varied from 10 to 58% and ERβ — 12% to 80%, indicating significant heterogeneity of estrogen receptor expression in tumors of different patients. The mean ERβ expression level was approximately 2-times higher compared to ERα (42.1±15.3% vs 21.4±11.3%; p<0.001). It allows to consider ER>β as a major estrogen target in NSCLC tissue. The level of ERα and ERβ expression in NSCLC tissue is independent of gender, smoking status, and the histological type of the tumor. Increased ERβ expression was detected only in male patients with lung adenocarcinoma in comparison with squamous cell carcinoma (p=0.02). The assessment of the correlation between ERα and ERβ in both the whole cohort of patients and subgroups with clinically relevant disease parameters revealed that the level of one marker does not predict the other one’s expression. The coefficient of determination, which characterizes how differences in one variable can be explained by the difference in a second variable, was less than 25% in any comparison group. The authors consider that the high level of ERβ expression and ERα coexpression in NSCLC tissue substantiates the clinical perceptiveness of a new treatment option for the disease, namely, adjuvant hormone (antiestrogen) therapy.
