Sleep quality, anxiety and depression in advanced lung cancer: patients and caregivers.

OBJECTIVE: To investigate the clinical implications of sleep quality, anxiety and depression in patients with advanced lung cancer (LC) and their family caregivers (FCs). METHODS: A total of 98 patients with advanced LC and their FCs (n=98) were recruited from the Oncology Department in Nanfang Hospital. The Pittsburgh Sleep Quality Index (PSQI), consisting of seven components that evaluate subjective sleep quality, sleep latency, duration of sleep, sleep efficiency, sleep disturbances, sleep medication usage and daytime dysfunction, was used to assess sleep quality. Using the tool of Zung Self-rating Anxiety Scale (SAS) and Zung Self-rating Depression Scale (SDS), we tested the patients' status of anxiety and depression, respectively. RESULTS: The prevalences of poor sleep quality, anxiety and depression in patients were 56.1%, 48.9% and 56.1%, respectively, while those in FCs were 16.3%, 32.6% and 25.5%, respectively. Patients had higher PSQI, SAS and SDS scores than did FCs (p<0.05). Significant correlations were found between the patients' and FCs' scores of PSQI/SAS/SDS (p<0.05). Multivariate Cox regression analyses indicated that sleep disturbances in patients (HR 0.413, 95% CI 0.21 to 0.80, p=0.01) and the global PSQI score of FCs (HR 0.31, 95% CI 0.14 to 0.71, p=0.00) were independent risk factors for patients' first-line progression-free survival (PFS). Moreover, patients' sleep latency (HR 2.329, 95% CI 1.36 to 3.96, p=0.00) and epidermal growth factor receptor mutations (HR 1.953, 95% CI 1.12 to 3.38, p=0.01) were significant prognostic factors for their overall survival (OS). CONCLUSIONS: We demonstrated that presence of sleep disturbances in patients with advanced LC and the global PSQI Score of their FCs may be risk predictors for patients' poor first-line PFS. Patients' sleep latency was a potential risk factor for their OS.

The prognostic value of adding systemic inflammation response index to Epstein-Barr virus DNA in childhood nasopharyngeal carcinoma: A real-world study.

BACKGROUND: To assess the prognostic value of the systemic inflammation response index (SIRI) combined with plasma load of Epstein-Barr virus (EBV) DNA in children and adolescents with locoregionally advanced nasopharyngeal carcinoma (CALANPC). METHODS: A total of 205 consecutive patients with CALANPC were enrolled. We used recursive partitioning analysis (RPA) to classify patients into various risk groups, with a primary endpoint of overall survival (OS). RESULTS: Elevated SIRI (≥1.53) and EBV DNA (≥4000 copy/ml) were significantly associated with inferior OS in CALANPC. RPA categorized patients into low- and high-risk groups based on prognostic factors. Survival curves showed excellent discrimination in OS (95.3% vs 77.6%; p < 0.001) between the low- and high-risk groups. A significant improvement was confirmed using the prognostic methods for conventional TNM staging systems (p < 0.05). CONCLUSIONS: The combination of SIRI with EBV DNA provided a more detailed understanding of patient risks, and enhanced risk discrimination in CALANPC.

The effect of adding concurrent chemotherapy to radiotherapy for stage II nasopharyngeal carcinoma with undetectable pretreatment Epstein-Barr virus DNA: Retrospective analysis with a large institutional-based cohort.

Little is known about the value of adding concurrent chemotherapy (CC) to radiotherapy for stage II nasopharyngeal carcinoma (NPC) with undetectable (0 copies/mL) pretreatment Epstein-Barr Virus (EBV) DNA in the intensity-modulated radiotherapy (IMRT) era. To address this question, the present study retrospectively reviewed 514 patients with newly diagnosed stage II NPC and undetectable pretreatment EBV DNA from Sun Yat-sen University Cancer Center between March 2008 and October 2016. Clinical characteristics and survival outcomes between concurrent chemoradiotherapy (CCRT) and IMRT alone groups were compared. Propensity score matching analysis was conducted to control for confounding factors. Although CCRT group had significantly higher proportions of stage N1 disease than IMRT alone group before matching (85% vs. 61%, p < 0.001), no statistically significant differences were noted for OS (97.8% vs. 98.1%, p = 0.700), DFS (93.4% vs. 94.5%, p = 0.846), DMFS (96.0% vs. 96.9%, p = 0.762), and LRFS (97.3% vs. 98.1%, p = 0.701). After 1:1 propensity-score matching, 177 pairs were identified. Patients in each group were found to be well balanced in baseline characteristics and risk factors (all P > 0.05). The five-year OS (96.9% vs. 98.2%, p = 0.302), DFS (92.0% vs. 95.2%, p = 0.777), DMFS (95.2% vs. 97.6%, p = 0.896), and LRFS (97.3% vs. 97.6%, p = 0.328) rates remain comparable for both CCRT and RT alone groups. Additionally, subgroup analysis still failed to observe any significant survival benefit for the addition of CC to IMRT for N1 disease (P>0.05 for all). Our results indicated that IMRT alone appeared to achieve comparable survival to CCRT for stage II NPC with undetectable pretreatment EBV DNA.

NK homeobox 2.2 functions as tumor suppressor in colorectal cancer due to DNA methylation.

Aim: The role of NK homeobox 2.2 (NKX2.2) in human colorectal cancer (CRC) remains to be unveiled. This study was designed to explore the epigenetic regulation and function of NKX2.2 in human CRC. Methods: The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets were used to assess the methylation data of NKX2.2 in CRC. Six CRC cell lines (HCT116, SW480, HT29, LOVO, SW1116, SW640) and 20 pairs of primary CRC tumor and normal tissues were utilized to explore the function of NKX2.2 in CRC using Sequenom EpiTYPER®, verified by cloning-based bisulfite sequencing analysis, semi-quantitative reverse transcription PCR, western blot, cell viability assessment, plate clone formation assay , and transwell assays. Results: Bioinformatic analysis showed that NKX2.2 was significantly hypermethylated in primary tumors compared to normal tissues (p < 0.05). Our study also found that NKX2.2 methylation was upregulated (p<0.05) in tumors than normal tissues. In vitro experiments demonstrated that 5-aza-2'-deoxycytidine downregulated the methylation of NKX2.2 and retrieved its expression of mRNA and protein levels (p<0.05). No significant association was found between the NKX2.2 methylation and sex, age, tumor differentiation, TNM stage, CEA, CA199, and fecal occult blood (p>0.05). Kaplan-Meier analysis indicated that NKX2.2 hypermethylation showed a trend but not statistical significance for predicting poor overall survival in CRC patients (p=0.33). NKX2.2 overexpression suppressed cell proliferation, colony formation, and inhibited tumor invasion and migration in CRC cells (both p<0.05). Conclusions: This study indicates that NKX2.2 is a tumor suppressor in CRC due to hypermethylation.

Lymphocyte-to-C-reactive protein ratio is a potential new prognostic biomarker for patients with lung cancer.

Aim: To compare and evaluate the prognostic value of various pretreatment combinations of inflammatory factors in patients with lung cancer (LC). Materials & methods: This study enrolled 1005 patients with LC and categorized into a discovery cohort and a validation cohort. Results: A combination of Lymphocyte-to-C-reactive protein levels (LCR) demonstrated the highest correlation with poor first-line progression-free survival (PFS) and overall survival (OS) (p < 0.05), but not disease-free survival (p > 0.05) compared with other parameters in LC patients. Decreased preoperative LCR was an independent prognostic factor for first-line PFS and OS (p < 0.05), but not disease-free survival (p > 0.05) in patients. Conclusion: Pretreatment LCR is a promising biomarker for first-line PFS and OS in patients with LC.

Prognostic Implications of Tripartite Motif Containing 24 Expression Levels in Patients with Solid Tumors: A Systematic Review and Meta-Analysis.

Objective: To systematically investigate the prognostic implications of tripartite motif containing 24 (Trim 24) expression levels in Patients with solid tumors. Materials and Methods: Pubmed, Embase, China National Knowledge Infrastructure, and Wanfang databases were searched through December 2017 to identify studies examining the relationship between Trim 24 expression levels and outcomes in solid tumor patients. The hazard ratios (HRs) with corresponding 95% confidence intervals were used to evaluate the association between Trim 24 and overall survival (OS). Results: Ten studies with 1370 patients were included. The overall pooled prevalence for Trim 24 overexpression was 59.0% (p < 0.01). Moreover, the pooled HR of Trim 24 for OS was 0.43 (p = 0.04) by univariate analysis in 10 articles (1370) and 0.62 (p = 0.08) by multivariate analysis in 5 studies (845). Trim 24 over-expression was associated with tumor invasiveness (odds ratio [OR] = 2.05, p < 0.01) and tumor-node-metastasis stage (OR = 2.42, p = 0.03). Conclusions: This study demonstrated that Trim 24 expression levels may be a useful prognostic biomarker in patients with solid tumors.
