INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2024; 39:ivae109. [PMID: 38851874 PMCID: PMC11222299 DOI: 10.1093/icvts/ivae109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 05/02/2024] [Accepted: 06/07/2024] [Indexed: 06/10/2024]
Abstract
OBJECTIVES Smokers comprise the majority of surgical patients with primary lung cancer. Epidermal growth factor receptor (EGFR) mutation-negative status impacts the treatment of recurrence. However, the prognostic impact of cigarette smoking stratified by EGFR mutation status has not been reported. Therefore, we assessed its impact on patients with resected lung cancer. METHODS We retrospectively analysed 362 consecutive patients who underwent complete resection for stage 1 primary lung cancer at our institution between 2012 and 2021. The EGFR mutation status was evaluated using the real-time polymerase chain reaction. We compared the overall survival (OS) and disease-free survival (DFS) between patients with and without a history of smoking. RESULTS The EGFR mutation-negative group included 194 patients, of whom 160 (83%) had a history of smoking. Male sex (P < 0.01), forced expiratory volume in 1 s (P < 0.01) and adenocarcinoma (P < 0.01) showed significant differences between the groups. In the EGFR mutation-positive group, the 5-year OS and DFS were similar regardless of smoking status (OS: 86% vs 75%; DFS: 73% vs 73%). In the EGFR mutation-negative group, the 5-year OS and DFS were significantly poorer in the smoking group (OS: 87% vs 65%, P = 0.05; DFS: 84% vs 54%, P = 0.01). Deaths from other diseases were relatively high (n = 19, 53%). CONCLUSIONS Cigarette smoking may be associated with a poor prognosis in EGFR mutation-negative lung cancer but had no impact on the prognosis of the EGFR mutation-positive group. This finding underscores the potential influence of smoking on the treatment of lung cancer recurrence but also highlights its significance in contributing to death from other diseases.

Abstract
Aim: To explore the association between sex and immune checkpoint inhibitors (ICIs). Materials & methods: We assessed the difference in survival outcomes from ICIs between sexes using an interaction test. Results: 108 studies representing 70,243 patients were included. In the first-line setting, the pooled interaction HR was 0.97 (95% CI: 0.91-1.04). In the subsequent-line setting, the pooled interaction HR was 0.85 (95% CI: 0.77-0.95). When ICIs were given as perioperative therapy or as systemic therapy in patients with positive PD-L1 expression, both men and women obtained equal survival benefits. Conclusion: Both sex, line of therapy, cancer (sub)type and PD-L1 status should be taken into account in the assessment of risk versus benefit when deciding to offer ICIs to patients.

Abstract
Objective Lung cancer is often diagnosed at an advanced stage and survival has been poor, although long-term studies have been rare. We analyzed data on survival in lung cancer from Denmark, Finland, Norway, and Sweden over a 50-year period (1971-2020). Methods Relative 1- and 5-year survival data were obtained from the NORDCAN database for 1971-2020. We used generalized additive models to estimate survival trends over time and uncertainty of these estimates. We additionally calculated conditional survival from the 1st to 5th year (5/1-year), estimated annual changes in survival rates, and determined significant breaking points. Results In 2016-2020, 5-year survival rate for lung cancer was best for Norwegian men (26.6%) and women (33.2%). The sex difference was significant and it was found for each country. Survival improved modestly until the year 2000, after which time survival curves increased steeply and kept the linear shape to the end of follow-up, indicating consistent improvement in survival. Survival curves for 1- and 5/1-year survival were almost superimposable, indicating that deaths in the first year were approximately as many as in the subsequent 4 years, thus marking sustained long-term survival. Conclusion We could document a positive development in lung cancer survival with steep upward trends after the year 2000. Intensions for curative treatment have been increasing and the outcomes have been improving with the help of novel imaging methods. Pathways for facile patient access to treatment have been instituted. Close to 90% of the patients are ever smokers. National anti-smoking acts and alerting people who smoke about early symptoms may be beneficial, as metastatic lung cancer remains difficult to cure.

Abstract
BACKGROUND Studying sex differences in the efficacy of immunotherapy may contribute to the practice of the precision medicine, especially in non-small cell lung cancer (NSCLC), a kind of cancer with sexual bimorphism. METHODS Published randomized controlled trials (RCTs), published by PubMed, Medline, Embase, and Scopus, before 15 June 2022, testing immunotherapy (CTLA-4 or PD-1/L1 inhibitor alone, combination or with chemotherapy) versus non-immunotherapy (receiving chemotherapy or placebo only) were included to assess different efficacy between males and females. The primary endpoint was overall survival (OS). This meta-analysis was registered with PROSPERO (CRD42022298439). RESULTS Sixteen RCTs, involving 10,155 patients with advanced NSCLC, was collected in this meta-analysis. The pooled HR comparing immunotherapy vs non-immunotherapy were 0.76 (95%CI 0.71-0.81) for males and 0.74 (95%CI 0.63-0.87) for females. The pooled HRs comparing immune-checkpoint inhibitors (ICIs) plus chemotherapy versus chemotherapy were 0.79 (95%CI 0.70-0.89) for males and 0.63 (95%CI 0.42-0.92) for females. The pooled HRs comparing ICIs versus chemotherapy were 0.74 (95%CI 0.67-0.81) for males and 0.83 (95%CI 0.73-0.95) for females. In squamous NSCLC, the pooled HRs comparing immunotherapy vs non-immunotherapy were 0.73 (95%CI 0.58-0.91) for males and 0.74 (95%CI 0.37-1.48) for females. In non-squamous NSCLC, the pooled HRs comparing immunotherapy versus non-immunotherapy were 0.62 (95%CI 0.71-0.94) for males and 0.59 (95%CI 0.39-0.89) for females. CONCLUSION Compared to chemotherapy, immunotherapy can improve the prognosis of patients with advanced NSCLC. Meanwhile, there are sex differences in the efficacy of immunotherapy.KEY MESSAGECompared to chemotherapy, immunotherapy can improve the prognosis of patients with advanced NSCLC.The most interesting thing in this study is that immunotherapy showed significant sex differences in the treatment of squamous NSCLC.

Abstract
Global survival studies have shown favorable development in most cancers but few studies have considered laryngeal cancer, particularly over extended periods or in populations for which medical care is essentially free of charge. We analyzed laryngeal and lung cancer incidence and survival in Finland (FI) and Sweden (SE) over a 50-year period (1970–2019) using data and statistical tools from the Nordcan database. Laryngeal cancer reached an incidence maximum in FI men in 1965, which in SE men occurred over 10 years later and peaking at 42% of the FI maximum. The FI incidence halved in 20 years while halving of the SE rate took almost twice as long. At maximum the male rate exceeded the female rate 20 times in FI and 10 times in SE. Incidence rates for lung cancer were approximately 10 times higher than those for laryngeal cancer, and they peaked 5 to 10 years after laryngeal cancer in both countries. The female lung cancer rates increased through the follow-up time but laryngeal cancer rates were relatively stable. Relative 1-year survival data for laryngeal cancer remained at around 85% through 50 years, and 5-year survival lagged constantly around 65%. For lung cancer 1-year survival improved and reached about 50% by 2019. Even 5-year survival improved reaching 20 to 30%, except for FI men. Incidence rates for laryngeal and lung cancers have drastically decreased in FI and SE men parallel to reduced smoking prevalence. In females, rates have clearly increased in lung but not in FI laryngeal cancer. This finding warrants further investigations into possible contributing factors, other than smoking. Survival in laryngeal cancer has not improved compared to the positive development in lung cancer. Historical smoking prevalence was unrelated of survival trends. As long-term survival in these cancers remains discouraging, the most efficient way to fight them is to target the main cause and promote non-smoking.

Abstract
Introduction Patients with small‐cell lung cancer (SCLC) have a very poor prognosis. However, a subset of SCLC achieves long‐term survival. The objective of this study was to investigate factors and pattern of long‐term survival in patients with limited‐stage small cell lung cancer (LS‐SCLC) who achieved a complete response (CR) after chemoradiotherapy. Patient and Methods This was a single‐center retrospective study. The analysis of hazard ratio (HR) and 95% confidence interval (CI) was performed using Cox proportional hazards model. For pattern analysis, the date of recurrence was used as the endpoint. The nominal categorical variables were analyzed by the χ2 test. Survival was estimated using the Kaplan–Meier model, and the results were reported as the median and interquartile range. Results We identified 162 patients, median age was 64.7 (56.2–70.2) years, and 94 (58%) were females. Eighty‐one patients (50%) had recurrence during follow‐up. Gastroesophageal reflux disease (GERD) (HR, 0.65; 95% CI, 0.45–0.93; p = 0.016) and neurological paraneoplastic syndrome (PNS) (HR, 0.46; 95% CI, 0.29–0.72; p < 0.001) were independent factors associated with improved overall survival (OS). Patients with GERD had prolonged recurrence free survival (RFS) compared to patients without GERD (median, 29.1 months vs. 13.9 months, p < 0.001), whereas patients with neurological PNS had a reduced recurrence rate compared to those patients without neurological PNS (No. [%], 8 [20.5] vs. 73 [59.3], p < 0.001). Conclusions Patients with LS‐SCLC achieving a CR after chemoradiotherapy, GERD, and neurological PNS were associated with improved OS. GERD and neurological PNS were associated with longer RFS and lower recurrence rate, respectively.

Abstract
BACKGROUND No effective molecular targeted therapy has been established for SCC. We conducted a comprehensive study of SCC patients using RNA-sequencing and TCGA dataset to clarify the driver oncogene of SCC. METHOD Forty-six samples of 23 patients were totally analyzed with RNA-sequencing. We then searched for candidate-oncogenes of SCC using the TCGA database. To identify candidate oncogenes, we used the following 2 criteria: (1) the genes of interest were overexpressed in tumor tissues of SCC patients in comparison to normal tissues; and (2) using an integrated mRNA expression and DNA copy number profiling analysis using the TCGA dataset, the DNA copy number of the genes was positively correlated with the mRNA expression. RESULT We identified 188 candidate-oncogenes. Among those, the high expression of SLC38A7 was a strong prognostic marker that was significantly associated with a poor prognosis in terms of both overall survival (OS) and recurrence-free survival in the TCGA dataset (P < 0.05). Additionally, 202 resected SCC specimens were also subjected to an immunohistochemical analysis. Patients with the high expression of SLC38A7 (alternative name is sodium-coupled amino acid transporters 7) protein showed significantly shorter OS in comparison to those with the low expression of SLC38A7 protein [median OS 3.9 years (95% confidence interval, 2.4-6.4 years) vs 2.2 years (95% confidence interval, 1.9-4.1 years); log rank test: P = 0.0021]. CONCLUSION SLC38A7, which is the primary lysosomal glutamine transporter required for the extracellular protein-dependent growth of cancer cells, was identified as a candidate therapeutic target of SCC.

Abstract
STUDY DESIGN This was a retrospective study. OBJECTIVE Evaluate the prognosis and surgical outcomes of patients with spinal metastasis from lung cancer undergoing surgical treatment. SUMMARY OF BACKGROUND DATA The spine is the most common site of metastatic lesions in patients with lung cancer. There have been a few studies, all small cohorts studying prognosis and surgical outcomes and the results were discordant. MATERIALS AND METHODS A retrospective study on a prospectively collected database was conducted. Data collected were the following: age, tobacco use, tumor histology, American Spinal Injury Association score, revised Tokuhashi score, ambulatory status, perioperative complications, postoperative adjuvant treatment, and survival time. Univariate and multivariate analyses were performed to identify the prognostic factors of survival. RESULTS The authors studied 87 patients with a mean age of 61.3±1.9 years. Median survival was 4.1±0.8 months. Twenty-eight patients (32.2%) lived >6 months and 14 patients (16.1%) lived >12 months. The medical complication rate was 13.8% and the surgical complication rate was 5.7%. The 30-day mortality rate was 4.6%. Univariate analysis showed tobacco use, revised Tokuhashi score, preoperative and postoperative American Spinal Injury Association score, postoperative walking ability, postoperative radiotherapy, and postoperative chemotherapy were prognostic factors. There was no significant difference in survival between adenoma lung cancers, nonadenoma lung cancers, and small cell lung cancers (P=0.51). Multivariate analysis revealed tobacco use, revised Tokuhashi score, postoperative walking ability, postoperative radiotherapy, and postoperative chemotherapy affected the survival. CONCLUSIONS This is the largest reported study of patients with spinal metastasis from lung cancer undergoing spinal surgery. It is the first study showing that tobacco use has a negative impact on survival. Spinal surgery improves the quality of life and offers nonambulatory patients a high chance of regaining walking ability with an acceptable risk of complications.

Abstract
Background Smoking cessation is a highly important preparation before thoracic surgery. We examined the effects of short-term smoking cessation intervention before pulmonary resection on postoperative pulmonary complications (PPCs). Methods A retrospective analysis of prospectively collected data was performed for 753 patients who underwent curative surgical resection for thoracic malignancy at 3 institutions. Patients with a smoking history were instructed to quit smoking. After confirming smoking cessation by at least four weeks before surgery, surgical resection was performed. Subjects were classified into three groups based on their smoking status: abstainers (anyone who had stopped smoking for at least 4 weeks but less than 2 months), former smokers (anyone who had abstained from smoking for more than two months prior to surgery), and never smokers (those who had never smoked). We examined the relationship between the preoperative smoking status and PPCs. Results Surgery was performed for 660 primary lung cancers and 93 metastatic lung tumors. The smoking statuses were classified as follows: abstainers (n=105, 14%), former smokers (n=361; 48%) and never smokers (n=287, 38%). The incidence of PPCs among abstainers, former smokers and never smokers was 15%, 8% and 6%, respectively (P=0.01). The mean duration of post-operative chest tube drainage among abstainers, former smokers and never smokers was 3.2, 2.2 and 2.2 days, respectively (P=0.04). The mean post-operative hospital stay among abstainers, former smokers and never smokers was 12.1, 10.6 and 10.2 days, respectively (P=0.07). There was no 30-day mortality in the cohort. Conclusions Short-term smoking cessation intervention did not enough reduce the PPCs as much as in former or never smokers.

Abstract
Background Squamous cell lung carcinoma (LUSC) was closely associated with smoking which was known to have a distant immunosuppression effect. In this study, we aimed to explore the relationship between immune cells and clinical outcomes of LUSC patients with smoking history. Methods The immune cell infiltration and RNA expression profiles of LUSC patients were collected from The Cancer Genome Atlas (TCGA). Then, the correlation between immune cell infiltration and clinical characteristics was explored. According to the level of immune cell infiltration, LUSC patients with smoking history were divided into high or low group to screen the differentially expressed lncRNAs and mRNAs. The prediction of target genes was performed by miRanda. Finally, the prognostic value of a certain signature was confirmed in an independent dataset. Results Higher abundance of tumor-infiltrating T follicular helper (Tfh) cells together with a lower abundance of resting memory CD4 T cells had been found in LUSC current reformed smokers for ≤15 years and current smoking patients. Moreover, Tfh cell infiltration was not only associated with better overall survival (OS) but also varied from different degrees of TNM stage. Low expression of lncRNA PWRN1 and its potential regulating genes DMRTB1, PIRT, APOBEC1, and ZPBP2 were associated with better OS. Combining PWRN1 and four regulating genes as a signature, patients with higher-level expression of the signature had shorter survival time in not only the TCGA but also in the GEO dataset. Conclusions It was found that Tfh cells presented higher infiltration in LUSC current reformed smokers for ≤15 years and current smokers, while resting memory CD4 T cells had lower infiltration. The signature consisting of PWRN1 as well as its predicted targeted mRNAs was dysregulated in different levels of Tfh cell infiltration and might indicate patients' OS.

Prognostic Impact of Smoking Period in Patients with Surgically Resected Non-small Cell Lung Cancer. Ann Surg Oncol 2020; 28:685-694. [PMID: 32676867 DOI: 10.1245/s10434-020-08851-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Accepted: 06/19/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND The pack-year index, which is calculated by multiplying a smoking period by the number of cigarette packs smoked per day, is frequently used to investigate the risk of developing lung cancer. Notably, however, whether the smoking period or the number of packs per day is more predictive of postoperative prognosis remains unclear in non-small cell lung cancer (NSCLC) patients who receive curative lung resection. PATIENTS AND METHODS Initial screening included 2055 consecutive lung cancer patients who had underwent curative lung resection between 2000 and 2016 at a single center in Japan. Data from 1134 NSCLC patients with smoking history were ultimately analyzed. Time-dependent areas under the curve (AUCs) were used to compare diagnostic accuracy. RESULTS On univariate analysis, the number of packs smoked per day was not a significant predictor of disease-free survival (DFS; p = 0.2387) or overall survival (OS; p = 0.1357). On multivariable analysis, smoking period was an independent predictor of DFS and OS (both p < 0.0001). Time-dependent smoking period AUCs were superior to those of number of packs smoked per day. On subgroup analyses, patients with a smoking period ≥ 40 years had significantly shorter DFS and OS than those with a smoking period of < 40 years, independent of sex, clinical stage, and histological type. CONCLUSIONS Smoking period was a significant prognostic indicator in NSCLC patients who underwent curative lung resection, which should be validated in further prospective and/or multicenter studies with large sample sizes.

Abstract
Background: Circular RNAs (circRNAs) are crucial regulators in human cancers, including nonsmall cell lung cancer (NSCLC). In this study, we aim to explore the biological functions and molecular mechanisms of circ_0074027 in NSCLC. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to determine the expression of circ_0074027, paired like homeodomain 1 (PITX1) mRNA, microRNA-335-5p (miR-335-5p), and cullin 4B (CUL4B) mRNA. The feature of circ_0074027 was analyzed by RNase R digestion assay. Flow cytometry analysis was adopted to analyze cell cycle and cell apoptosis. Cell counting kit-8 (CCK-8) assay and colony formation assay were performed to assess cell proliferation. Western blot assay was conducted to measure protein levels. Dual-luciferase reporter and RNA pull-down assays were carried out to verify the relationships among circ_0074027, miR-335-5p, and CUL4B. The murine xenograft model was established to investigate the role of circ_0074027 in vivo. Results: High expression of circ_0074027 was found in NSCLC tissues and cells. Circ_0074027 knockdown suppressed cell viability, cell cycle process, and colony formation and promoted apoptosis in NSCLC cells in vitro and inhibited tumor growth in vivo. Circ_0074027 acted as a sponge of miR-335-5p. The effect of circ_0074027 knockdown on NSCLC progression was weakened by miR-335-5p inhibition. Moreover, CUL4B was a target gene of miR-335-5p. CUL4B overexpression reversed the inhibitory effects on cell viability, cell cycle process, and colony formation and the promotional effect on cell apoptosis caused by miR-335-5p in NSCLC. Conclusion: Circ_0074027 facilitated NSCLC cell progression through regulating miR-335-5p/CUL4B axis.

Abstract
Emerging evidence has manifested the critical effect of abnormally expressed circular RNAs (circRNAs) on the initiation and progression of non-small cell lung cancer (NSCLC). Although circRNA circCCDC66 has been revealed to elicit facilitating impact on cell growth and metastasis in colon cancer, the potential biological function and regulatory mechanism of it in NSCLC still require to be explored. In this study, circCCDC66 in NSCLC cells was highly expressed. Downregulation of circCCDC66 impaired cell proliferation, migration and invasion whereas boosted cell apoptosis in NSCLC. Data from molecular mechanism assays testified that circCCDC66 bound with miR-33a-5p in NSCLC cells. And miR-33a-5p inhibition could rescue the suppressive effect of circCCDC66 knockdown on NSCLC progression. In addition, karyopherin subunit alpha 4 (KPNA4) in NSCLC cells was proofed to be directly targeted by miR-33a-5p. Moreover, through rescued-function assays, we observed that upregulating KPNA4 expression could countervail the restraining function of silenced circCCDC66 on NSCLC progression. Furthermore, signal transducer and activator of transcription 3 (STAT3) was validated to activate CCDC66 transcription and thereby promote circCCDC66 expression in NSCLC cells. Briefly, STAT3-induced circCCDC66 upregulation accelerates NSCLC progression via miR-33a-5p/KPNA4 axis, suggesting circCCDC66 as a promising biomarker in NSCLC treatment.

Abstract
BACKGROUND Circular RNAs (circRNAs) have been considered as key regulators of cancer biology. However, the functional role of hsa_circ_0023404 in non-small cell lung cancer (NSCLC) and its regulatory mechanism are still almost unknown. METHODS The expression of hsa_circ_0023404, miR-217 and zinc finger E-box-binding homeobox 1 (ZEB1) was evaluated by quantitative real-time polymerase chain reaction. The role of hsa_circ_0023404 in NSCLC progression was determined using cell count kit-8 assay, transwell migration and invasion assay. Luciferase reporter assay was performed to assess the interaction of hsa_circ_0023404, miR-217 and ZEB1 in NSCLC cells. RESULTS The expression of hsa_circ_0023404 was upregulated in NSCLC tissues, as well as in NSCLC cell lines. High hsa_circ_0023404 expression predicted short overall survival in NSCLC. Functionally, knockdown of hsa_circ_0023404 inhibited the proliferation, migration and invasion of NSCLC cells. In the further molecular mechanism study, hsa_circ_0023404 was shown to interact with miR-217/ZEB1 axis to contribute to the growth of NSCLC cells. CONCLUSION hsa_circ_0023404 promotes the proliferation, migration and invasion of NSCLC cells by regulating miR-217/ZEB1 axis, providing a fresh perspective on circRNAs in NSCLC development.

Abstract
Natural dietary components have become the subject of an increasing amount of interest due to the side effects of anticancer treatment. Pterostilbene, an analog of resveratrol, is primarily found in grapes, and has been suggested to exert antioxidant and anticancer effects in different tumor types. The present study aimed to investigate the antitumor effects and molecular mechanisms of pterostilbene in the human lung squamous cell carcinoma (SqCC) cell line, H520. The results of the present study indicate that pterostilbene significantly reduced cell viability and induced S phase arrest, and that treatment with pterostilbene was associated with the downregulation of cyclin A and cyclin E, as with the upregulation of p21 and p27 expression in H520 cells. In the apoptosis analysis, pterostilbene induced S phase accumulation and the activation of caspase-3, −8 and −9 in H520 cells, potentially through the activation of extrinsic and intrinsic apoptotic pathways. Additionally, the in vivo study demonstrated that pterostilbene effectively inhibited lung SqCC growth in a H520 ×enograft model. Given the in vitro and in vivo antitumor effects of pterostilbene demonstrated in the present study, pterostilbene may serve a novel and effective therapeutic agent to for patients with SqCC.

Abstract
BACKGROUND Smoking cessation is important in the management of patients who require pulmonary resection. However, the impact of short-term smoking cessation on the surgical outcome remains unclear. METHODS A retrospective study was conducted on patients with stage I to III primary lung cancer who underwent resection between 2012 and 2016. The rate of operative mortality and morbidity were evaluated according to smoking status. The relationship between the preoperative interval of smoking cessation and pulmonary complications after surgery was also examined. RESULTS This study included 666 patients, of whom 256 (38.4%) were never smokers and 410 (61.6%) were smokers. Significant differences were found between the smokers and never smokers regarding the 90-day mortality rate (2.0% versus 0%, p = 0.025) and respiratory complications (22.3% versus 3.5%, p < 0.001). A multivariate analysis indicated that smoking (odds ratio [OR] 2.8, p = 0.017), forced expiratory volume in 1 second/forced vital capacity less than 0.7 (OR 2.6, p = 0.001), percentage of diffusing capacity of the lung for carbon monoxide less than 40% (OR 4.2, p = < 0.001), and clinical stage of lung cancer (OR 2.3, p = 0.005) were predictors of pulmonary complications after pulmonary resection. In comparison with never smokers, the ORs for pulmonary complications at each cessation interval (current smoker/cessation for <1month, 1 to 3 months, 3 to 6 months, 6 to 12 months, and >12 months) were 12.9 (p < 0.001), 10.3 (p < 0.001), 8.5 (p < 0.001), 6.3 (p = 0.011), 6.0 (p = 0.003), and 5.0 (p < 0.001), respectively. CONCLUSIONS A longer period of cessation might be more effective for reducing the risk of pulmonary complications. Smoking cessation at any time is valuable for lung cancer surgery.

Abstract
BACKGROUND Although several complicated models have been built to evaluate the prognosis of NSCLC patients receiving chemotherapy, simple economic models are still needed to give a preliminary survival assessment of these patients. MATERIAL AND METHODS This study retrospectively assessed the clinical and biological parameters of 223 patients with advanced NSCLC. Univariate and multivariate analyses of overall survival (OS) and progression-free survival (PFS) for the parameters and the prognostic score were assessed. RESULTS Performance status (PS) score=1, smoking history, fibrinogenemia, thrombocytosis, increased lactate dehydrogenase (LDH) level, and anemia were independent predictors of poor prognosis in the univariate analysis of OS and were assessed in multivariate analysis. There was a significant difference in PS=1 (HR=2.134, p<0.0001), increased LDH level (HR=1.508, p=0.014), thrombocytosis (HR=1.547, p=0.012), and smoking history (HR=1.491, p=0.008), based on which the patients were classified into 3 risk groups: low risk (0-1 points), moderate risk (2 points), and high risk (3-5 points). At p values of <0.0001, the median OS was 565, 340, and 273 days and the median progression-free survival was 250, 209, and 135 days, respectively in these 3 risk groups. CONCLUSIONS We established a new prognostic score model using PS, LDH level, PLT count, and smoking history to predict the survival of patients receiving first-line chemotherapy for advanced NSCLC, which might be useful in clinical practice.

Abstract
Background Non-small-cell lung cancer (NSCLC) represents the most frequent subtype of lung cancer. MicroRNAs (miRNAs) have attracted a lot of attention with regard to their clinical significance and crucial biological functions in various human cancers. This study aimed to investigate the prognostic significance of microRNA-421 (miR-421) and its correlation with tumor progression in NSCLC. Materials and methods Expression levels of miR-421 in both serum and tissue samples were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The prognostic value of miR-421 was evaluated using Kaplan–Meier survival analysis and Cox regression assay. To explore the functional role of miR-421 during NSCLC progression, cell experiments were carried out. Results Expression of serum and tissue miR-421 was upregulated in the NSCLC patients compared with the normal controls (all P<0.001), and the expression showed a significant correlation between the serum samples and tissues (R=0.475, P<0.001). The increased miR-421 expression was associated with positive lymph-node metastasis and advanced TNM stage (all P<0.05). Moreover, patients with high miR-421 expression had poor overall survival compared with those with low expression (log-rank P=0.007). The overexpression of miR-421 proved to be an independent prognostic factor for NSCLC (HR=1.991, 95% CI=1.046–3.791, P=0.036). According to the cell experiments, the proliferation, migration and invasion of NSCLC cells were suppressed by knockdown of miR-421. Conclusion Overexpression of miR-421 serves as a prognostic biomarker and may be involved in the promotion of tumor progression in NSCLC.

Abstract
PURPOSE To compare overall survival (OS) after radiofrequency (RF) ablation and stereotactic body radiotherapy (SBRT) at high-volume centers in patients with early-stage non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Cases in the National Cancer Database of stage 1a and 1b NSCLC treated with primary RF ablation or SBRT from 2004 to 2014 were included. Patients treated at low-volume centers, defined as facilities below the 95th percentile in volume of cases performed, were excluded. Outcomes measured include OS and rate of 30-day readmission. The Kaplan-Meier method was used to estimate OS. The log-rank test was used to compare survival curves. Propensity score matched cohort analysis was performed. P < .05 was considered statistically significant. RESULTS The final cohort comprised 4,454 cases of SBRT and 335 cases of RF ablation. Estimated median survival and follow-up were 38.8 months and 42.0 months, respectively. Patients treated with RF ablation had significantly more comorbidities (P < .001) and higher risk for an unplanned readmission within 30 days (hazard ratio = 11.536; P < .001). No difference in OS for the unmatched groups was found on multivariate Cox regression analysis (P = .285). No difference was found in the matched groups with 1-, 3-, and 5-year OS of 85.5%, 54.3%, and 31.9% in the SBRT group vs 89.3%, 52.7%, and 27.1% in the RF ablation group (P = .835). CONCLUSIONS No significant difference in OS was seen between patients with early-stage NSCLC treated with RF ablation and SBRT.

Efficacy of thoracic radiotherapy in patients with stage IIIB-IV epidermal growth factor receptor-mutant lung adenocarcinomas who received and responded to tyrosine kinase inhibitor treatment. Radiother Oncol 2018; 129:52-60. [PMID: 29703499 DOI: 10.1016/j.radonc.2018.03.007] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2017] [Revised: 02/05/2018] [Accepted: 03/12/2018] [Indexed: 12/19/2022]
Abstract
PURPOSE Large-scale, prospective, randomized studies of the efficacy of thoracic radiotherapy (RT) in patients with unresectable stage IIIB-IV epidermal growth factor receptor (EGFR)-mutant lung adenocarcinomas who received and responded to EGFR tyrosine kinase inhibitor (TKI) treatment are not currently available. Therefore, we designed a propensity score-matched, nationwide, population-based, cohort study for estimating the effects of thoracic RT on patients with EGFR-mutant lung adenocarcinomas. PATIENTS AND METHODS We analyzed patients with unresectable stage IIIB-IV EGFR mutant lung adenocarcinomas and categorized them into two groups according to treatment modality and compared their outcomes; groups 1 and 2 consisted of patients who received EGFR TKI treatment alone until tumor progression and those who received and responded to EGFR TKI treatment and subsequently received thoracic RT for lung tumors, respectively. The patients in groups 2 and 1 were matched at a ratio of 1:4. RESULTS The matching process yielded a final cohort of 1475 patients (1180 and 295 patients in groups 1 and 2, respectively) who were eligible for further analysis. According to both univariate and multivariate Cox regression analyses, the adjusted hazard ratios (aHRs) (95% confidence interval [CI]) derived for thoracic RT for lung tumor after EGFR TKI use and tumor response (group 2) compared with EGFR TKI treatment alone (group 1) was 0.72 (0.60-0.85). CONCLUSIONS Thoracic RT might be associated with overall survival in patients with unresectable stage IIIB-IV EGFR-mutant lung adenocarcinomas who received and responded to EGFR TKI treatment.

Abstract
Emerging studies demonstrated that miRNAs played fundamental roles in lung cancer. In this study, we attempted to explore the clinical significance of the miRNA signature in different histological subtypes of non-small cell lung cancer (NSCLC). Three miRNome profiling datasets (GSE19945, GSE25508 and GSE51853) containing lung squamous cell carcinoma (SCC), lung adenocarcinoma (ADC) and large cell lung cancer (LCLC) samples were obtained for bioinformatics and survival analysis. Moreover, pathway enrichment and coexpression network were performed to explore underlying molecular mechanism. MicroRNA-375 (miR-375), miR-203 and miR-205 were identified as differentially expressed miRNAs (DEmiRNAs) which distinguished SCC from other NSCLC subtypes. Pathway enrichment analysis suggested that Hippo signaling pathway was combinatorically affected by above mentioned three miRNAs. Coexpression analysis of three miRNAs and the Hippo signaling pathway related genes were conducted based on another dataset, GSE51852. Four hub genes (TP63, RERE, TJP1 and YWHAE) were identified as the candidate targets of three miRNAs, and three of them (TP63, TJP1 and YWHAE) were validated to be downregulated by miR-203 and miR-375, respectively. Finally, survival analysis further suggested the prognostic value of three-miRNA signature in SCC patients. Taken together, our study compared the miRNA profiles among three histological subtypes of NSCLC, and suggested that a three-miRNA signature might be potential diagnostic and prognostic biomarkers for SCC patients.

Abstract
BACKGROUND Few large, prospective, randomized studies have investigated the value and optimal application of neoadjuvant chemoradiotherapy followed by surgery (trimodality therapy) or definitive concurrent chemoradiotherapy (CCRT) for patients with thoracic esophageal squamous cell carcinoma (TESCC). METHODS The authors analyzed data from patients with TESCC in the Taiwan Cancer Registry database. To compare their outcomes, patients with TESCC were enrolled and categorized into the following groups according to treatment modality: group 1, those who underwent surgery alone; group 2, those who received trimodality therapy; and group 3, those who received definitive CCRT. Group 1 was used as the control arm for investigating the risk of mortality after treatment. RESULTS In total, 3522 patients who had TESCC without distant metastasis were enrolled. Multivariate Cox regression analysis indicated that a Charlson comorbidity index score ≥3, American Joint Committee on Cancer stage ≥IIA, earlier year of diagnosis, alcohol consumption, cigarette smoking, and definitive CCRT were significant, independent predictors of a poor prognosis. After adjustment for confounders, adjusted hazard ratios and 95% confidence intervals (CIs) for overall mortality in patients with clinical stage I, IIA, IIB, IIIA, IIIB, and IIIC TESCC were 2.01 (95% CI, 0.44-6.18), 1.65 (95% CI, 0.99-2.70), 1.48 (95% CI, 0.91-2.42), 0.66 (95% CI, 1.08-1.14), 0.39 (95% CI, 0.26-0.57), and 0.44 (95% CI, 0.24-0.83), respectively, in group 2; and 2.06 (95% CI, 1.18-3.59), 2.65 (95% CI, 1.76-4.00), 2.25 (95% CI, 1.49-3.39), 1.34 (95% CI, 0.79-2.28), 0.82 (95% CI, 0.57-1.17), and 0.93 (95% CI, 0.51-1.71), respectively, in group 3. CONCLUSIONS Trimodality therapy may be beneficial for the survival of patients with advanced-stage (IIIA-IIIC) TESCC, and CCRT might be an alternative to surgery alone in these patients.

Abstract
PURPOSE Few large, prospective, randomized studies have compared the effects of postoperative radiotherapy (PORT) in pathological N2 (pN2) with those of surgical resection alone. in terms of long-term survival in lung adenocarcinoma (adenoCA; wild-type [WT] epidermal growth factor receptor [EGFR]) and squamous cell carcinoma (squCA) settings. This nationwide cohort study clarifies the role of PORT in the survival of pN2 lung adenoCA (WT EGFR) and squCA patientsPatients and Methods: We analyzed data of patients with adenoCA (WT EGFR) and squCA collected from the Taiwan Cancer Registry database. The patients were categorized into five groups according to the treatment modality: Group 1 (surgery alone), Group 2 (adjuvant chemotherapy [CT] alone), Group 3 (adjuvant radiotherapy [RT] alone), Group 4 (adjuvant concurrent chemoradiotherapy [CCRT]), and Group 5 (adjuvant sequential CT and intensity-modulated RT [IMRT]). RESULTS We enrolled 588 lung adenoCA (WT EGFR) and squCA patients without distant metastasis. After adjustments for age at surgery, surgical years, and Charlson comorbidity index scores, the multivariate Cox regression analysis demonstrated that adjusted HRs (aHRs; 95% confidence intervals [CIs]) for the overall mortality of female lung adenoCA (WT EGFR) patients were 0.257 (0.111-0.594), 0.530 (0.226-1.243), 0.192 (0.069-0.534), and 0.399 (0.172-0.928) in Groups 2, 3, 4, and 5, respectively. For male lung squCA patients, the aHRs (95% CIs) for overall mortality were 0.269 (0.160-0.451), 0.802 (0.458-1.327), 0.597 (0.358-0.998), and 0.456 (0.265-0.783) in Groups 2, 3, 4, and 5, respectively. CONCLUSIONS Adjuvant CCRT or sequential CT and IMRT at ≥5000 cGy significantly reduced the mortality rate of female lung adenoCA (WT EGFR) and male squCA pN2 patients.

Abstract
OBJECTIVES The influence of blood group antigens on cancerogenesis is shown for distinct tumor types, yet the impact of Rhesus blood group antigens in lung cancer is not clarified. MATERIALS AND METHODS To investigate the impact of Rhesus blood groups a non-small cell lung cancer (NSCLC) collective (n = 1047) was analyzed retrospectively. Using a second cohort of n = 340 primarily operated stage I-III NSCLC patients, we evaluated immunohistochemistry of CD47-antibody stained tissue samples in correlation to histopathologic subtype and Rhesus blood group. RESULTS AND CONCLUSION In 516 of 1047 patients blood group data were available. Seven different RhCE phenotypes were grouped as "··ee," "ccE·," and "C·E·." Adenocarcinoma patients with Rh "··ee" revealed improved overall survival (29 (21.2-36.8) m; HR 1.00 [index]) compared with Rh "ccE·" (19 (1.9-36.1) m; HR 1.76 [1.15-2.70]) and Rh "C·E·" (10 (7.4-12.6) m; HR 2.65 [1.70-4.12]) univariately (P < .001) and multivariately (P < .001). Rh "··ee" showed reduced incidence of CNS-metastasis (P = .014) and metastasis count (P = .032) in stage IV adenocarcinoma. Immunohistochemistry associated CD47-positivity with adenocarcinomas (n = 340, P = .048). In n = 51 cases blood group data were available. The prognostic effect of Rh "··ee" compared with Rh "ccE·" and Rh "C·E·" was stated (P = .001), foremost in CD47-positive adenocarcinomas (Rh "··ee" vs. Rh "ccE·" and Rh "C·E·," P = .008). Inversely Rh "ccE·" or Rh "C·E·" was found beneficial in CD47-negative non-adenocarcinomas (P = .046). Phenotypic RhCE expression may be an independent prognostic factor for overall survival in adeno-NSCLC. We hypothesize an erythrocytic-immunologic interaction with tumor tissue, possibly altered by RhCE and CD47, resulting in a metastatic prone condition.

Abstract
The aim of this present investigation was to evaluate the clinicopathologic characteristics, oncogenic drivers, and prognosis of former smokers with non‐small‐cell lung cancer (NSCLC), and to compare them with those of the current and never smokers. This investigation was a single‐institution retrospective study of 2289 NSCLC patients, who were classified as former, current, or never smokers. A collection was made of the clinicopathological characteristics, spectra of well‐identified driver genes and survival rates. The survival rates were compared using log‐rank test, and independent prognostic factors, identified using Cox regression analysis. Of 2289 NSCLC patients, 257 (11.2%) were former smokers; 868 (37.9%), current smokers; and 1164 (50.9%), never smokers. Compared with the current, the former were characterized by older age at diagnosis (64.3y vs. 59.9y; P < 0.001), earlier TNM stage (stage I, 47.9% vs. 39.5%; P = 0.017), fewer solid predominance in adenocarcinomas (16.2% vs. 29.5%; P = 0.005), and more EGFR mutation (33.2% vs. 20.7%; P < 0.001) but less KRAS mutation (6.7% vs. 11.9%, P = 0.041). No statistically significant survival differences were observed between the former and current. However, the light former smokers presented favorable overall survival when compared with the light current and heavy former or current (the light former vs. the heavy former, P = 0.028; the light former vs. the light current, P = 0.048; and the light former vs. the heavy current, P = 0.048). Our findings suggest that the former smokers with NSCLCs can have distinctive clinicopathologic characteristics, oncogenic drivers, and prognosis, and they, especially the light former, can benefit from smoking cessation.

Abstract
Adenocarcinoma (AC) and squamous cell carcinoma (SCC) of non-small cell lung carcinoma (NSCLC) have different clinical presentations, morphologies, treatments, and prognoses. Recent studies suggested that fundamental genetic alterations related to carcinogenesis of each tumor type may be different. In this study, we investigated the genomic alterations of 47 primary NSCLC samples (22 ACs and 25 SCCs) as well as the corresponding normal tissue using array comparative genomic hybridization. Frequent copy number alterations (CNAs), which were identified in more than 68% of all of the cases, were evaluated in each subtype (SCC and AC), and a CNA signature was established. Among these CNAs, 37 genes from the SCCs and 15 genes from the ACs were located in a region of gain, and 4 genes from the SCCs and 13 genes from the ACs were located in a region of loss. The most frequent gain was located on 3q26-29 including the gene TP63 in SCCs and 7q11.23 and 7q36.3 in ACs. Moreover, we identified 3 genetically distinct groups (group I [16 SCC] with CNA signature of SCC; group II [7 SCC + 8 AC], which has a genetically distinctive CNA signature from SCC and AC; and group III [2 SCC + 14 AC] with CNA signature of AC) by gene clustering extracted from CNAs, which are associated with a prognosis. The present study contributed to the molecular characterization of AC and SCC of NSCLC and showed a subtype of tumor that has a unique genetic CNA signature. However, further study about the significance of these 3 distinct groups and their usefulness as a diagnostic marker of identified CNAs is necessary.
