Abstract

BACKGROUND:Lung cancer has changed significantly during the past 2 decades in its epidemiology and treatment. This retrospective analysis used data from 7 major areas of China over 10 years to evaluate clinicopathologic and surgical treatment trends of lung cancer in China during the past decade. METHODS:Data from 7184 patients with primary lung cancer who were treated between 2005 and 2014 in 8 provinces of China were retrospectively collected. Their clinicopathologic features and surgical treatment information were recorded. Simple linear regression models and the Cochrane-Armitage trend test were used to assess temporal trends. RESULTS:The proportion of female patients (from 57.4% to 59.6%; P < .001) and nonsmoking patients (from 37.1% to 48.9%; P < .001) and of patients with a family history of malignant tumors (from 7.0% to 11.5%; P < .001) increased significantly. The percentage of adenocarcinomas increased significantly (from 36.4% to 53.5%; P < .001), with a decrease in squamous cell carcinomas (from 45.4% to 34.4%; P < .001). After 2008, the application of minimally invasive surgery significantly increased in China (from 2.4% in 2008 to 34.4% in 2014; P < .001), with a decline in the rate of conversion to open operation (from 14.3% in 2008 to 4.8% in 2014; P = .146) and an increase in the proportion of systematic mediastinal lymph node dissection (from 50.0% in 2008 to 84.1% in 2014; P = .001). CONCLUSIONS:This study investigated recent 10-year trends in the clinicopathologic features and surgical treatment of lung cancer in China and found significant important changes. These findings provide valuable information and evidence for the future control of the disease in China.

摘要

背景: 在过去的 20 年中,肺癌流行病学学和治疗方面发生了显著的变化。该回顾性分析使用了中国 7 个主要地区 10 年的数据,评估了过去十年中国肺癌的临床病理和外科治疗趋势。 方法: 回顾性收集中国 8 个省 2005 年至 7184 年间收治的 2014 例原发性肺癌患者的资料。记录其临床病理特征和手术治疗信息。使用简单线性回归模型和Cochrane-Armitage趋势检验评估时间趋势。 结果: 女性患者 (从 57.4% 到 59.6%; P < .001) 和不吸烟患者 (从 37.1% 到 48.9%; P < .001) 的比例并且有恶性肿瘤家族史的患者 (从 7.0% 到 11.5%; P < .001) 显著增加。腺癌的百分比显著增加 (从 36.4% 到 53.5%; P <.001),鳞状细胞癌的百分比降低 (从 45.4% 到 34.4%; P <.001)。2008 后,微创手术在中国的应用显著增加 (从 2008 年的 2.4% 增加到 2014 年的 34.4%; P <.001),随着向开放式操作的转化率下降 (从 2008 年的 14.3% 降至 2014 年的 4.8%; P = .146)系统性纵隔淋巴结清扫的比例增加 (从 2008 年的 50.0% 增加到 2014 年的 84.1%; P = .001)。 结论: 本研究调查了近 10 年来中国肺癌临床病理特征和外科治疗的趋势,并发现了重大变化。这些发现为今后我国防治该病提供了有价值的信息和证据。

METHODS::Pulmonary artery sling is a rare congenital anomaly of the origin and course of the left pulmonary artery. Patients with this condition typically present with respiratory failure in young infancy, and asymptomatic cases are uncommon. We describe the case of an adult patient with a lung adenocarcinoma of the right upper lobe, extending into the hilum and superior mediastinum, and with a previously unknown pulmonary artery sling anomaly. The local invasiveness of the tumor and the peculiar vascular anatomy contributed to a unique surgical scenario, wherein multiple reconstructive procedures were required.

METHODS::Patients with idiopathic pulmonary fibrosis (IPF) have higher risk of developing lung cancer, for example, squamous cell carcinoma (SCC), and show poor prognosis, while the molecular basis has not been fully investigated. Here we conducted DNA methylome analysis of lung SCC using 20 SCC samples with/without IPF, and noncancerous lung tissue samples from smokers/nonsmokers, using Infinium HumanMethylation 450K array. SCC was clustered into low- and high-methylation epigenotypes by hierarchical clustering analysis. Genes hypermethylated in SCC significantly included genes targeted by polycomb repressive complex in embryonic stem cells, and genes associated with Gene Ontology terms, for example, "transcription" and "cell adhesion," while genes hypermethylated specifically in high-methylation subgroup significantly included genes associated with "negative regulation of growth." Low-methylation subgroup significantly correlated with IPF (78%, vs. 17% in high-methylation subgroup, p = 0.04), and the correlation was validated by additional Infinium analysis of SCC samples (n = 44 in total), and data from The Cancer Genome Atlas (n = 390). The correlation between low-methylation subgroup and IPF was further validated by quantitative methylation analysis of marker genes commonly hypermethylated in SCC (HOXA2, HOXA9 and PCDHGB6), and markers specifically hypermethylated in high-methylation subgroup (DLEC1, CFTR, MT1M, CRIP3 and ALDH7A1) in 77 SCC cases using pyrosequencing (p = 0.003). Furthermore, low-methylation epigenotype significantly correlated with poorer prognosis among all SCC patients, or among patients without IPF. Multivariate analysis showed that low-methylation epigenotype is an independent predictor of poor prognosis. These may suggest that lung SCC could be stratified into molecular subtypes with distinct prognosis, and low-methylation lung SCC that significantly correlates with IPF shows unfavorable outcome.

METHODS::The role of Fyn-related kinase (FRK) in malignant tumors remains controversial. Our study investigated the function of FRK in lung cancer. Immunohistochemistry staining and generating a knockout of FRK by CRISPR/Cas9 in H1299 (FRK-KO-H1299) cells were strategies used to explore the role of FRK. Immunohistochemistry staining indicated that FRK expression was elevated in 223 lung cancer tissues compared to 26 distant normal lung tissues. FRK contributed to poor survival status in lung cancer patients and acted as a predictor for poor prognosis of lung cancer. Knockout of FRK by CRISPR/Cas9 markedly inhibited proliferation, invasion, colony formation and epithelial-mesenchymal transition (EMT) process in the lung cancer cell line H1299. Further exploration indicated that FRK-KO damaged the stemness phenotype of H1299 by inhibiting CD44 and CD133 expression. Seahorse detection and a U-13 C flux assay revealed that FRK-KO induced metabolism reprogramming by inhibiting the Warburg effect and changing the energy type in H1299 cells. Epidermal growth factor stimulation recovered the expression of FRK and biological functions, metabolic reprogramming and stemness phenotype of H1299 cells. FRK plays an oncogenic role in lung cancer cells via a novel regulation mechanism of enhancing the stemness of H1299 cells by inducing metabolism reprogramming, which finally promotes EMT and metastasis. Our study also indicates that FRK could be used as a potential therapeutic target for drug development.
