IntroductionHepatoid adenocarcinoma of the lung (HAL) is a special type of adenocarcinoma originating from the lung with adenoid- and hepatocyte-like differentiation. HAL is rare in clinical practice. Here, we present the case of a patient with HAL.Case presentationA 59-year-old man was admitted to the hospital 4 days because of lung mas observed. Chest computed tomography (CT) revealed a lobulated mass shadow in the right lower lobe, approximately 3.5 × 3.3 cm in size. CT-guided percutaneous biopsy of the right lower lung was performed. The pathological results indicated a moderately to poorly differentiated adenocarcinoma. The patient underwent thoracoscopic right middle and lower lobectomy and systematic lymph node dissection. The postoperative pathology was primary HAL, with the staging of T2bN2M0 (stage III A). Recurrence-free survival and overall survival were 6 and 19 months, respectively Preoperatively, the level of alpha-fetoprotein was negative; however, after recurrence, it increased to 87.8.ConclusionPulmonary hepatoid adenocarcinoma is a rare subtype of malignant lung tumor, combined silicosis is more rare. Early surgical intervention can benefit patients in the early stages of the disease, whereas chemotherapy remains the main systemic treatment modality for postoperative and advanced stages. With the increasing popularity of genetic testing, it is important to focus on improving genetic examination.
BACKGROUND:Abnormal expression of protein tyrosine kinase 6 (PTK6) has been proven to be involved in the development of gynecological tumors. However, its immune-related carcinogenic mechanism in other tumors remains unclear. OBJECTIVE:The aim of this study was to identify PTK6 as a novel prognostic biomarker in pan-cancer, especially in lung adenocarcinoma (LUAD), which is correlated with immune infiltration, and to clarify its clinicopathological and prognostic significance. METHODS:The prognostic value and immune relevance of PTK6 were investigated by using bio-informatics in this study. PTK6 expression was validated in vitro experiments (lung cancer cell lines PC9, NCI-H1975, and HCC827; human normal lung epithelial cells BEAS-2B). Western blot (WB) revealed the PTK6 protein expression in lung cancer cell lines. PTK6 expression was inhibited by Tilfrinib. Colony formation and the Cell Counting Kit-8 (CCK-8) assay were used to detect cell proliferation. The wound healing and trans-well were performed to analyze the cell migration capacity. Then flow cytometry was conducted to evaluate the cell apoptosis. Eventually, the relationship between PTK6 and immune checkpoints was examined. WB was used to estimate the PD-L1 expression at different Tilfrinib doses. RESULTS:PTK6 was an independent predictive factor for LUAD and was substantially expressed in LUAD. Pathological stage was significantly correlated with increased PTK6 expression. In accordance with survival analysis, poor survival rate in LUAD was associated with a high expression level of PTK6. Functional enrichment of the cell cycle and TGF-β signaling pathway was demonstrated by KEGG and GSEA analysis. Moreover, PTK6 expression considerably associated with immune infiltration in LUAD, as determined by immune analysis. Thus, the result of vitro experiments indicated that cell proliferation and migration were inhibited by the elimination of PTK6. Additionally, PTK6 suppression induced cell apoptosis. Obviously, PD-L1 protein expression level up-regulated while PTK6 was suppressed. CONCLUSION:PTK6 has predictive value for LUAD prognosis, and could up regulated PD-L1.

The key N 6 methyladenosine (m 6 A) RNA methylation regulator is associated with multiple tumour progression. However, the m 6 A‐associated regulators that influence non‐small cell lung cancer (NSCLC) development have not been fully clarified. The m 6 A regulator expression pattern of NSCLC patients from The Cancer Genome Atlas (TCGA) dataset was identified. Aberrations of m6A modulators are related to NSCLC development via cBioPortal database. Furthermore, we found that IGF2BP2, IGF2BP3, HNRNPA2B1, and FTO are significantly correlated with advanced stage disease or clinical outcomes in NSCLC by UALCAN and Kaplan–Meier plot. Bioinformatics analysis showed that m 6 A modulators (IGF2BP2, IGF2BP3, HNRNPA2B1, and FTO) are associated with immunomodulator and immune infiltration expression in NSCLC via the Tumor Immune Estimation Resource (TIMER) database. The co‐expression between these m6A‐associated modulators was analysed by protein‐protein interaction networks. Finally, we found that HNRNPA2B1 promotes NSCLC development in vitro by regulating cell proliferation and metastasis functions via Cell Counting Kit 8 (CCK8) and transwell assay. Our study showed that HNRNPA2B1 is a promising target and biomarker for cancer therapy in NSCLC.
Long noncoding RNA (lncRNA), specifically the upregulation of lncRNA NR2F1 antisense RNA 1 (NR2F1-AS1), has been involved in the progression of non-small cell lung cancer (NSCLC), but the mechanisms that underlie this remain unclear. In this study, the expression of NR2F1-AS1, miR-363-3p, and SOX4 was assessed in NSCLC cells. A loss-of-function assay was used to measure the tumorigenicity of NSCLC cells. The glycolysis and glutamine metabolism of NSCLC cells was also measured via extracellular acidification rate, consumption of glucose and glutamine, and production of lactate and ATP. The relationships among NR2F1-AS1, miR-363-3p, and SOX4 were detected via dual-luciferase reporter assay. HK-2, GLS1, and SOX4 levels were also analyzed. We found that both NSCLC tissues and cells had higher levels of NR2F1-AS1. Silencing of NR2F1-AS1 inhibited the tumorigenicity of cells in vitro and reduced the glycolysis and glutamine metabolism of NSCLC cells. Regarding its mechanism, NR2F1-AS1 positively regulated the SOX4 level by sponging miR-363-3p. Furthermore, miR-363-3p inhibition or SOX4 overexpression reversed the repressing role of sh-NR2F1-AS1 in the tumorigenicity of NSCLC cells. In summary, NR2F1-AS1 promotes the tumorigenicity of NSCLC cells by regulating miR-363-3p/SOX4.
Vasculogenic mimicry (VM) is associated with aggressive cancer cells. Salvianolic acid A (Sal-A), an antioxidant and anti-inflammatory agent, has bioactive properties from Salvia miltiorrhiza Bunge. Current investigation aspired to explore the activity of Sal-A in the VM formation of non-small cell lung cancer (NSCLC) and the mechanism underling this function. The CCK8, the scratch and boyden chemotaxis assay were presented to describe NSCLC cells viability, migration and invasion capabilities, respectively. The protein expression was verified by western blotting. In this report, Sal-A caused a reduction in viability, metastasis and capillaries structure formation of NSCLC cells. Additionally, Sal-A markedly prevented the key VM related proteins, containing EphA2, VE-cadherin and MMP2. Besides, Sal-A significantly diminished p-PI3K, p-Akt and p-mTOR level in NSCLC cells. More importantly, SC79 pretreatment reversed Sal-A inhibits NSCLC cells viability, metastasis and VM formation. These data exhibit that Sal-A could block VM network formation in NSCLC cells through modulating the PI3K/Akt/mTOR signalling pathway.

Objective To Evaluate the feasibility of video-assisted thoracoscopic surgery(VATS) reoperation for recurrent primary spontaneous pneumothorax.Methods The clinical and follow-up date of 35 recurrent pneumothorax patients,who received reoperation from January 2004 to November 2013 at the Beijing Haidian Hospital and Peking University People's Hospital were retrospectively reviewed.Chi square,t test and Kaplan-Meier curve was used to evaluate risk factors.Results The relapsed 35 patients included male 30,female 5.The median age was 22 years old(range 16-50 years).The median operating time was 100 min (range 40-190 min),the median blood loss was 50 ml (range 5-200 ml) and the median postoperative stay in the hospital was 7 days(range 3-13 days).VATS was successfully performed for all patients,without conversion.No morbidity or mortality occurred.The median follow-up time was 49months(range 12-133 months).Adhesions were observed from 34 patients,wherein,the severity ranged from mild to dense.New bullae or blebs were found in 26 patients (74.29%),9 (34.62%) of which were adjacent to the stapled incisal margin.No bullae or blebs were found on the 9 patients (26.71%)that underwent reoperation within 18 months from their initial operation.No recurrence was observed during the follow-up.Conclusion The recurrence of spontaneous pneumothorax was mostly caused by the formation of new bullae or blebs near the staple lines.Reoperation for recurrent pneumothorax was safe and advocated.VATS operation includes the dissection of pleural adhesions,wedge resection of neoformative bullae or blebs and elimination of the residual apical space.
Objective To investigate the influence factors for contralateral recurrence of spontaneous pneumothorax following thoracoscopic surgery in adolescents. Methods Two hundred and fifty-five adolescents with spontaneous pneumothorax were enrolled in the study,including 43 patients with postoperative contralateral recurrence and 212 patients without recurrence. The demographic characteristics,X-ray imaging,perioperative and operative information were compared between patients with and without contralateral recurrence. The influence factors for contralateral recurrence were analyzed by univariate and multivariate logistic regression analysis. Results Univariate analysis suggested that there were significant differences in height,body mass index,onset frequency of spontaneous pneumothorax,thoracic transverse diameters to anteriorposterior diameters,thoracic length and perioperative alveolus occurrence between two groups( P 0.05).Multiple logistic regression analysis suggested that thoracic transverse diameters to anteriorposterior diameters,perioperative alveolus occurrence,body mass index and onset frequency of spontaneous pneumothorax were the influence factors for postoperative contralateral recurrence. Conclusion The patients with slim body,several onset frequencies,flat chest and several pulmonary bulla observed during operation have increased risks of contralateral recurrence in adolescents with spontaneous pneumothorax undergoing thoracoscopic surgery.
Objective To determine the indications for primary spontaneous pneumothorax in young patients after closed drainage.Methods From Jaunary 2007 to December 2012,139 young patients,who had chest tube drainage in spontaneous pneumothorax and full information by telephone follow-up,patients were divided into recurrence and recurrence-free group.The possible influence factors related to recurrence were statistically analyzed.Results Single factor and multi-factor analysis indi cated that in the aspect of self-factors,the edge of the lung in chest X-ray were independent factors for recurrence prediction (P < 0.05).Conclusion If the edge of lung is not smooth in X-ray,then VATS(video assisted thoracoscopic surgery) operation is needed.

Objective To assess the safety,effectiveness,indications and advantage of modified "Hemi-Clamshell" approach for giant anterior mediastinal tumor.Methods From Apr 2003 to May 2012,24 patients (18 males and 6 females,median aged 40 years old) with giant anterior mediastinal tumor (average dimension:11.3 cm × 9.3 cm) were treated through modified "Hemi-Clamshell" approach.In operation,anterolateral thoracotomy with sternum transection was performed through 3rd or 4th intercostal space from midclavicular line to contralateral parasternal line.Then a radical or palliative resection of the tumor was performed.Results There were no mortality and major morbidity peri-operatively.A myasthenic crisis occurred for a patient with thymoma and myasthenia gravis.16 operations were performed through 3rd intercostal space and 8 through 4th.15 cases of tumor were radically resectedaverage dimension of tumors was 11.2 cm × 9.1 cm while the other 9 were palliativly resectedthe average dimension of tumors was 11.3 cm × 9.5 cm.Because of the extranodal invasion of the tumor,14 patients received extended operations.All the patients were followed-up to Aug 2013,the overall period of follow-up were 6-124 months.The survival postoperative for the patients of radical resection group were 11-124 months and for the palliative resection group were 6-66 months.Conclusion Manufacture of the modified "Hemi-Clamshell" approach is fast and convenient,and the exploration of the mediastinal organs is satisfied.This modified approach can be used for great majority of the mediastinal tumors.This approach is suitable for promotion at the primary hospitals and the prospect of application is well.
Objective To discuss the feasibility of uniportal video-assisted thoracic surgery( VATS) technique applied to pulmonary bullae resection for the treatment of spontaneous pneumothorax. Methods Three hundred and twenty-seven cases undergoing video-assisted pulmonary bullae resction and pleurodesis were divided into uniportal VATS technique group( n = 194) and traditional two-port VATS technique group( n = 133). The clinical data including the operation time,postoperative thoracic cavity drainage volume,postoperative leakage time,postoperative extubation time,postoperative recurrence rate and perioperative staple-using number were compared between two groups. Results There were no significant differences in operation time,bleeding,postoperative recurrence,postoperative hospital stay and perioperative staple-using number between two groups( P 0. 05). The postoperative pain and wound numbness in the uniportal VATS technique group improved significantly compared with two-port VATS technique group( P 0. 05).Conclusion The uniportal VATS technique has similar effect with two-port VATS technique on spontaneous pneumothorax patients undergoing pulmonary bullae resction,but the patients using the uniportal technique have less pains and wound numbness after operation.
Objective To assess early and medium outcomes of pathologic N2 disease unexpectedly detected in patients undergoing total video-assisted thoracic surgery lobectomy for non-small cell lung cancer.Methods Between Sep.2006 and Dec.2010,348 patients with Non-small cell lung cancer underwent total video-assisted thoracic surgery lobectomy,and within them,35( 10.1% ) were found to have pathologic N2 disease after operation.We retrospectively reviewed the clinical and pathologic features of patients with unexpected N2 disease after video-assisted thoracic surgery lobectomy and their early and medium outcomes,including survival and recurrence pattern.Results No perioperative mortality was noted.26 patients received a lobectomy directly,and the other 9 patients after a wedge resection.All the patients had R0 resection.The medium operation time was 190 minutes and medium blood loss was 200ml.The medium stations and numbers of dissected N2 lymph nodes in operation were 4 and 10,respectively.And the medium stations and numbers of metastatic N2 Lymph nodes were 1 and 2,respectively.Among patients with pathologic N2 disease,18 (51.4%) had single-station involvement.The median duration of chest tube placement was 8 days.The median length of hospital stay was 11 days.15 complications occurred in 12 (34.3%) patients.All of the patients underwent adjuvant chemotherapy with platinum postoperatively.The median follow-up time was 23 months.The 1 - and 2-year overall survival (OS) was 80.9% and 67.9%,and the medium OS was not reached.During follow-up,16 (45.7%) patients had a recurrence.The pattern of recurrence was locoregional in 5,distant in 11.The 1 - and 2-year disease-free survival (DFS) was 71.9% and 44.2%,and the medium DFS was 20 months (95%,8.1 to 31.9 months).Divided the patients with pathologic N2 disease into two groups considering single-station involvement or not,the 1-and 2-year OS and DFS for the single-station group and for the multiple-station group were 87.7%,78.9% ; 88.9%,49.4%and 67.6%,59.1% ; 55.3%,39.5%.The medium DFS for both the two groups was 23 and 16 months respectively.Conclusion For non-small cell lung cancer with N0 disease confirmed by an exactly preoperative staging workups,if it is feasible in technology,a total video-assisted thoracic surgery lobectomy should be recommended.Even if N2 lymph node metastasis is unexpectedly detected postoperatively,the metastasis was mostly micro- or single-station involved,and a similar outcome with conventional thoracotomy can be achieved.
