BackgroundThe prognostic values of preoperative neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), and platelet/lymphocyte ratio (PLR) in non‐small cell lung cancer (NSCLC) have been previously described. This study assessed the prognostic values of other pretreatment complete blood cell parameters in Chinese patients with curatively resected NSCLC.MethodsA total of 1466 consecutive NSCLC patients who received curative surgery from January 1, 2005 to December 31, 2009 with complete data from pretreatment blood tests were enrolled in this retrospective study. Correlations between each blood test parameter and overall survival were examined by Kaplan–Meier method or Cox proportional hazards regression, followed by a stratification analysis of significant variables.ResultsOptimal cut‐off values of 0.55 for neutrophil/white blood cell ratio (NWR), 0.28 for lymphocyte/white blood cell ratio (LWR), 0.09 for monocyte/white blood cell ratio (MWR), 2.06 for NLR, 0.35 for MLR, 204.00 for PLR, and 38.25 for platelet/white blood cell ratio (PWR) were identified using X‐tile software. Univariate analysis suggested that NWR ≥ 0.55, LWR < 0.28, MWR ≥ 0.09, NLR ≥ 2.06, MLR ≥ 0.35, and PLR ≥ 204.00 predicted a poor prognosis in NSCLC patients. However, only NWR and MLR were identified as independent significant prognostic factors in multivariable analysis, especially in tumor node metastasis stage I and I/II/III NSCLCs.ConclusionPretreatment NWR, MWR, LWR, NLR, MLR, and PLR values are associated with poor overall survival for patients with curatively resected NSCLC. NWR and MLR are independent prognostic factors in curatively resected NSCLC.
Epithelioid hemangioendothelioma is a very rare, vascular, low‐grade malignant tumor found in the lungs, liver, bone, and other soft tissues. Most patients with pulmonary epithelioid hemangioendothelioma (PEH) are asymptomatic but usually present with multiple bilateral nodular lesions in the lungs. Currently, surgical lung biopsy, histology, and immunohistochemical methods are essential for diagnosis. However, there is no standard therapy for the treatment for PEH.Our paper describes the clinico‐radiologic features and genomics of PEH based on next‐generation sequencing (NGS) in a 43‐year‐old male we encountered. The patient came to the hospital with right chest pain. After investigation, a lesion in the middle lobe of the right lung was found, together with smaller multiple lesions in both lungs. After resection of the lesion, histopathological analysis showed positive findings for PEH. The patient's blood and tumor tissue were sent for NGS analysis for further investigation. Results from the analysis revealed mutations of multiple genes. The information obtained from the genomic analysis of PEH using NGS may be significant for the planning and monitoring of treatment for this disease.
e20626 Background: Apatinib, a small-molecule inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2), has been proved to be effective and safe in treating patients with advanced gastric cancer who failed to second-line chemotherapy. As the VEGFR-2 targeted therapy has made encouraging progress in the treatment of a broad range of malignancies, we aimed to explore the efficacy and safety of apatinib in treatment of advanced non-small cell lung cancer after the failure of chemotherapy or other targeted therapy. Methods: In this open-label single-arm, phase II study, patients were treated with apatinib alone in daily dose of 250 mg, po, in the second- or third-line setting. The primary endpoint was progression-free-survival (PFS) and the tumor response was determined according to the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. Results: From January 28, 2016 to December 31, 2016, 33 patients were enrolled, including 9 patients with squamous carcinoma and 24 patients with adenocarcinoma. Fourteen patients were detected as EGFR mutations and all the cases have no anaplastic lymphoma kinase (ALK) fusion gene. The median progression free survival (mPFS) of the whole group was 4.0 (95% confidence interval [CI], 0-8.2) months, while the mPFS of adenocarcinoma was 4.0 (95% CI, 2.1-5.9) months and the mPFS of squamous carcinoma was 5.5 (95% CI, 0-13.9) months (P = 0.245). Among the 33 patients, partial response was noted in 3 patients (9.09 %) and stable disease in 14 (42.42%). The disease control rate (DCR) was 51.52%. The common side effects of apatinib were hypertension, hand-foot syndrome and proteinuria, which accounted for 33.33%, 24.24%, and 15.15%, and no grade 3/4 adverse reactions occurred. The toxicity of apatinib was controllable and tolerable. Conclusions: Apatinib appears to be effective and safe for advanced non-small cell lung cancer after the failure of chemotherapy or other targeted therapy. Prospective studies are needed for further investigation.
Objective: This work was implemented to elucidate the miR-126-5p expression in the plasma of patients with sepsis-induced acute lung injury (ALI) and its correlation with inflammation and immune function. Methods:The peripheral blood of patients with sepsis-induced ALI was obtained, and the levels of inflammatory factors (interleukin-6 [IL-6],C-reactive protein [CRP], and procalcitonin [PCT]) were determined. Meanwhile, T lymphocyte subsets (CD3+, CD4+, and CD8+), and immunoglobulins (IgA, IgM, and IgG) were tested. miR-126-5p and TRAF6 mRNA expression in plasma was assessed. Receiver operating characteristic (ROC) curve was performed to assess the diagnostic accuracy of miR-126-5p in sepsis without ALI and sepsis with ALI. Correlation between miR-126-5p expression and clinical indicators was analyzed. The targets of miR-126-5p were predicted using the bioinformatics method, and the direct targets were verified through investigations.Results: miR-126-5p expression in plasma of patients with sepsis-induced ALI was reduced than that of patients with sepsis without ALI. miR-126-5p expression was negatively correlated with IL-6, CRP, and PCT but positively correlated with IgA, IgM, and IgG as well as CD3+, CD4+, and CD8+ in patients with sepsis-induced ALI. ROC curve suggested that miR-126-5p (AUC: 0.777; 95%CI: 0.689-0.866) could distinguish patients with sepsis with ALI from patients with sepsis without ALI. TRAF6 expression in patients with sepsis-induced ALI was higher than that in patients with sepsis without ALI.TRAF6 was a target gene of miR-126-5p, Conclusion: This research highlights that miR-126-5p is reduced in the plasma of patients with sepsis-induced ALI, and miR-126-5p relates to systemic inflammation and immune function indicators.
Background: Lichen sclerosus (LS) is a chronic inflammatory dermatosis that occurs mainly in the anogenital area and causes itching, soreness, atrophy and scarring, which may result in burying of the clitoris in females and phimosis in males. Photodynamic therapy (PDT) has been suggested during the past years as an alternative non-invasive treatment for LS, but there is still no meta-analysis to evaluate its efficacy and safety. Aims: To assess the efficacy and safety of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) for treatment of LS. Methods: We undertook a meta-analysis using the methodology of the Cochrane Collaboration and the guideline of PRISMA. A systematic literature search was carried out in PubMed, EMBASE, The Cochrane Library, WanFang Data, CBM and CNKI up to 30 June 2020. Randomized controlled trials (RCTs) were compared with ALA-PDT, corticosteroids or tacrolimus ointments for treating LS. The risk of bias for each trial was rated according to the Cochrane Handbook. Risk ratios (RR) with 95% confidence intervals (CI) were utilized to express the comparative outcomes. Results: We included 4 RCTs with a total of 184 participants. The meta-analysis showed ALA-PDT was better than topical ointments in treating LS (total effective rate: RR 1.38 [95% CI 1.19-1.60]). Conclusions: The current limited evidence supports the efficacy and safety of ALA-PDT in treating LS. The adverse reactions included pain, swelling, redness and exfoliation which would decrease with the continuing sessions of treatment. Further high-qualified RCTs of large samples are necessarily needed.
