Hypoxia-inducible factor-1 alpha (HIF-1α) plays a vital role in the initiation, evaluation and prognosis in lung cancer. The prognostic value of HIF-1α reported in diverse study remains disputable. Accordingly, a meta-analysis was implemented to further understand the prognostic role of HIF-1α in lung cancer. The relationship between HIF-1α and the clinicopathological characteristics and prognosis of lung cancer were investigated by a meta-analysis. PubMed and Embase were searched from their inception to January 2015 for observational studies. Fixed-effects or random-effects meta-analyses were used to calculate odds ratios and 95% confidence intervals of different comparisons. A total of 20 studies met the criteria. The results showed that HIF-1α expression in lung cancer tissues was significantly higher than that in normal lung tissues. Expression of HIF-1α in patients with squamous cell carcinoma was significantly higher than that of patients with adenocarcinomas. Similarly, non-small cell lung cancer (NSCLC) patients had higher HIF-1α expression than small cell lung cancer (SCLC) patients. Moreover, lymph node metastasized tissues had higher HIF-1α expression than non-lymph node metastasized tissues. A high level HIF-1α expression was well correlated with the expression of vascular endothelial growth factor and epidermal growth factor receptor in the NSCLC. Notably, NSCLC or SCLC patients with positive HIF-1α expression in tumor tissues had lower overall survival rate than patients with negative HIF-1α expression. It was suggested that HIF-1α expression may be a prognostic biomarker and a potential therapeutic target for lung cancer.

Extraskeletal Ewing's sarcoma (EES) is a branch of neuroectodermal tumor (PNET), which is very rare soft tissue sarcoma. We report a case of EES/PNET arising is the lung of a 67-yr-old man. Computed tomography, bone scintigraphy, and positron emission tomography confirmed the mass to have a primary pulmonary origin. The mass showed positive reactivity in the Periodic Acid Schiff (PAS) stain and MIC-2 immunoreactivity in immunohistochemical stain. Fluorescence in situ hybridization (FISH) was performed, which revealed an EWSR1 (Ewing sarcoma breakpoint region 1) 22q12 rearrangement. The diagnosis was confirmed both pathologically and genetically. The mass lesion was resected, and the patient is currently undergoing chemotherapy.

OBJECTIVETo study the relationship between expression of caveolin-1 (Cav-1) and pERK1/2 and prognosis in non-small cell lung cancer (NSCLC).
METHODSCav-1 and pERK1/2 protein expression was assessed by immunohistochemistry in samples obtained from 160 patients with NSCLC and 20 patients with normal lung tissue.
RESULTSNormal bronchial and alveolar epithelial cells were positive for Cav-1 (membranous and cytoplasmic staining patterns). The expression rate of Cav-1 in NSCLC was 65.6% (105/160), which was significantly lower than that in normal lung tissue (P = 0.002). The Cav-1-positive rates in well to moderately differentiated tumors and poorly differentiated tumors were 56.8% (46/81) and 75.7% (53/70), respectively (P = 0.015). The expression of Cav-1 was much higher in patients with lymph node metastasis (77.8%, compared with 55.7% in lymph node-negative group, P = 0.003). The expression was also higher in stage III to IV than in stage I to II disease (75.4%, compared with 58.2%, P = 0.024). The overall survival of patients with Cav-1-positive tumors (71.4%, 37.1% and 17.1% 1-, 3- and 5-year survival, respectively) was lower than those with Cav-1-negative tumors (89.1%, 69.1% and 43.6% 1-, 3- and 5-year survival, respectively, P = 0.000). On the other hand, normal bronchial and alveolar epithelial cells were negative for pERK1/2. The expression rate of pERK1/2 in NSCLC was 61.3%, which was significantly higher than that in normal lung tissues (P = 0.000). The pERK1/2-positive rates in well to moderately differentiated tumors and poorly differentiated tumors was 53.1% and 71.4%, respectively (P = 0.021). The expression of pERK1/2 was much higher in patients with lymph node metastasis (80.6%, compared with 45.5% in lymph node-negative group, P = 0.000). The expression of pERK1/2 was also higher in stage III to IV than in stage I to II disease (76.8%, compared with 49.5%, P = 0.426). The overall survival of patients with pERK1/2-positive tumors (74.5%, 42.9% and 19.4% 1-, 3- and 5-year survival, respectively) was lower than those with pERK1/2-negative tumors (82.3%, 56.5% and 37.1% 1-, 3- and 5-year survival, respectively, P = 0.002). Cav-1 and pERK1/2 expression showed negative correlation (P = 0.000).
CONCLUSIONSCav-1 expression is lower in NSCLC than in normal lung tissue, whereas pERK1/2 expression is higher in NSCLC. Positive expression of Cav-1 and overexpression of pERK1/2 correlates with tumorigenesis and tumor progression of NSCLC. Cav-1 and pERK1/2 may serve as potential markers for predicting prognosis in NSCLC.

BACKGROUND:
As the morbidity and mortality in lung cancer keep raising, we are here to discuss the effect of clinical features especially the initial symptomon on diagnosis and follow-up treatment of newly diagnosed lung cancer patients.
METHODS:
The clinical features of the 500 patients with lung cancer in our hospital from March, 2017 to May, 2017 were analyzed retrospectively, including the initial symptom, stage, biomarkers, pathology, etc. RESULTS: There were 266 famle (53.3%), 372 adenocarcinoma (74.4%), 285 smokers (58%), status score of most patients (98.2%) was 0-1. 58.2% (n=291) of all the patients got biomarkers test, of which epidermal growth factor receptor (EGFR) mutations was 61.2%(178/291), anaplasticlymphoma kinase (ALK) fusion gene positive was 4.1% (12/291). Smoking status, initial symptom, pathological typing, TNM staging and EGFR mutation were the main factors affecting follow-up treatment.
CONCLUSIONS
Patients with typical symptoms have shorter diagnosis time. Smoking status, lung cancer-related symptoms, pathology, TNM staging and EGFR mutation status are the main factors that affect the follow-up treatment.

Objective: To investigate the clinicopathological features, immunophenotype, molecular features and differential diagnosis of primary synovial sarcoma of the lung (PSSL). Methods: Twelve cases of PSSL were collected at Henan Provincial People's Hospital, during May 2010 and April 2021, and their clinicopathological parameters were summarized. SS18-SSX, H3K27Me3, and SOX2 were added to the original immunomarkers to evaluate their diagnostic value for PSSL. Results: The age of 12 patients when diagnosed ranged from 32 to 75 years (mean of 50 years). There were 7 males and 5 females, 2 left lung cases and 10 right lung cases. Of the 6 patients who underwent surgical resection, five cases were confined to lung tissue (T1), one case had mediastinal invasion (T3), two cases had regional lymph node metastasis (N1), and none had distal metastasis. Microscopically, 11 cases showed monophasic spindle cell type and one case showed biphasic type composed of mainly epithelial cells consisting of cuboidal to columnar cells with glandular and cribriform structures. It was difficult to make the diagnosis by using the biopsy specimens. Immunohistochemistry (IHC) showed CKpan expression in 8 of 12 cases; EMA expression in 11 of 12 case; TLE1 expression in 8 of 12 cases; S-100 protein expression in two of 12 cases; various expression of bcl-2 and vimentin in 12 cases, but no expression of SOX10 and CD34 in all the cases. The Ki-67 index was 15%-30%. The expression of SS18-SSX fusion antibody was diffusely and strongly positive in all 12 cases. SOX2 was partially or diffusely expressed in 8 of 12 cases, with strong expression in the epithelial component. H3K27Me3 was absent in 3 of 12 cases. SS18 gene translocation was confirmed by fluorescence in situ hybridization (FISH) test in all 12 samples. Six cases underwent surgery and postoperative chemotherapy, while the other six cases had chemotherapy alone. Ten patients were followed up after 9-114 months, with an average of 41 months and a median of 26 months. Five patients survived and five died of the disease within two years. Conclusions: PSSL is rare and has a broad morphological spectrum. IHC and molecular tests are needed for definitive diagnosis. Compared with current commonly used IHC markers, SS18-SSX fusion antibody has better sensitivity to PSSL, which could be used as an alternative for FISH, reverse transcription-polymerase chain reaction or next generation sequencing in the diagnosis of PSSL.

MicroRNAs (miRNAs), a class of small non-coding RNAs, mediate gene expression by either cleaving target mRNAs or inhibiting their translation. They have key roles in the tumorigenesis of several cancers, including non-small cell lung cancer (NSCLC). The aim of this study was to investigate the clinical significance of miR-638 in the evaluation of NSCLC patient prognosis in response to chemotherapy. First, we detected miR-638 expression levels in vitro in the culture supernatants of the NSCLC cell line SPC-A1 treated with cisplatin, as well as the apoptosis rates of SPC-A1. Second, serum miR-638 expression levels were detected in vivo by using nude mice xenograft models bearing SPC-A1 with and without cisplatin treatment. In the clinic, the serum miR-638 levels of 200 cases of NSCLC patients before and after chemotherapy were determined by quantitative real-time PCR, and the associations of clinicopathological features with miR-638 expression patterns after chemotherapy were analyzed. Our data helped in demonstrating that cisplatin induced apoptosis of the SPC-A1 cells in a dose- and time-dependent manner accompanied by increased miR-638 expression levels in the culture supernatants. In vivo data further revealed that cisplatin induced miR-638 upregulation in the serum derived from mice xenograft models, and in NSCLC patient sera, miR-638 expression patterns after chemotherapy significantly correlated with lymph node metastasis. Moreover, survival analyses revealed that patients who had increased miR-638 levels after chemotherapy showed significantly longer survival time than those who had decreased miR-638 levels. Our findings suggest that serum miR-638 levels are associated with the survival of NSCLC patients and may be considered a potential independent predictor for NSCLC prognosis.
