Abstract
BackgroundThe incidence of primary lung cancer (LC) in children and adolescence was rare. We analyzed data from a SEER database to better define the incidence, clinical characters, pathology, treatment, and outcomes of rare primary malignant pulmonary tumors in childhood and adolescence.MethodsPatients were chosen from the SEER database (SEER*Stat 8.4.0 software) from 2000 to 2019 and all patients were pathologically diagnosed with primary malignant tumors of the lung and bronchus. Demographic characteristics of patients (age, gender, race, primary site, laterality, location, differentiation grade, operation methods, histology, and history of radiotherapy and chemotherapy), as well as TNM stage and survival time, were collected.ResultsA total of 301 cases of children ≤19 years of age with a primary malignant pulmonary tumor were reported to the SEER database from 2000 to 2019. There were 143 men (47.5%) and 158 women (52.5%). Whites represented majority of patients (79.7%), followed by Black (13.6%) and others (6.7%). As for the primary site, the main site was the lower lobe (33.2%), followed by the upper lobe (26.9%). Most of the patients (80.4%) underwent surgery. Lobectomy (39.9%) is the main operation method. Only 28 (9.3%) patients received radiotherapy and 112 (37.2) patients received chemotherapy. Carcinoid tumor was the most common histology (29.6%), followed by pulmonary blastoma (PB) (22.3%), mucoepidermoid carcinoma (MEC) (12.3%), adenocarcinoma (10.3%), neuroendocrine tumor (NET) (5.7%), squamous cell carcinoma (SCC) (5.3%), atypical carcinoma (2.3%). The mean follow-up time was 100 months. For the entire group of children and adolescents, the 1-year OS was 89.1%, and the 3-year overall survival (OS) was 79.7%. the 5-year OS was 77.9%, the 10-year OS was 75.7%, and the 15-year OS was 73.9%. And 1-year lung cancer specificity survival (LCSS) was 89.8%, and the 3-year LCSS was 80.4%. the 5-year LCSS was 79.4%, the 10-year LCSS was 77.7%, and the 15-year LCSS was 75.9%. The OS of atypical carcinoma, carcinoid tumor, and MEC were in the top three.ConclusionsPrimary LC in children and adolescent were rare and histopathological diverse. Fortunately, children and adolescents with LC had an overall favorable outcome after treatment. Histology, differentiation grade, surgery, TNM stage, and therapeutic modalities have important influence on OS. The further treatment experience of each pathological type would make better evidence-based practice possible.

Abstract
Lung cancer has been one of the leading causes of cancer-related death worldwide, and non-small-cell lung cancer (NSCLC) accounts for the majority of lung cancer morbidity, yet the pathogenesis of NSCLC has not been fully elucidated. Recently, long-chain non-coding RNA (lncRNA) has attracted widespread attention. LncRNA is a type of non-coding RNA whose transcript length exceeds 200 nucleotides. After constant research, academics updated their understanding of lncRNA, especially its role in the biological processes of cancer cells, including epigenetic regulation, cell proliferation, and cell differentiation. Notably, examination of lncRNAs could serve as potential hallmarks for clinicopathological features, long-term prognosis, and drug sensitivity. Therefore, it is necessary to explore the functions of lncRNA in NSCLC and innovate potential strategies against NSCLC based on lncRNA-related research. Herein, we reviewed the functions of lncRNA in the occurrence, diagnosis, treatment, and prognosis of NSCLC, which not only help promote a comprehensive view of lncRNA in NSCLC, but also shed light on the potential of lncRNA-based diagnosis and treatment of NSCLC.

The efficacy and toxicity of maintenance therapy with bevacizumab plus pemetrexed versus bevacizumab/pemetrexed alone for stage IIIB/IV nonsquamous non-small cell lung cancer: A meta-analysis of randomized controlled trials. J Clin Pharm Ther 2021; 47:157-167. [PMID: 34617297 DOI: 10.1111/jcpt.13534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 09/16/2021] [Accepted: 09/22/2021] [Indexed: 11/29/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVE Whether maintenance therapy with bevacizumab (Bev) + pemetrexed (Pem) can achieve greater clinical benefits than Bev or Pem alone for stage IIIB/IV nonsquamous non-small cell lung cancer (NSCLC) remains unclear. We assessed the antitumour effect and toxicity of maintenance Bev+Pem versus maintenance with single-agent Bev/Pem in this meta-analysis. METHODS Appropriate randomized controlled trials (RCTs) were screened using electronic databases (Google Scholar, PubMed, Embase, Scopus, ScienceDirect, Ovid MEDLINE, Cochrane and Web of Science). The endpoints were progression-free survival (PFS), overall survival (OS) and adverse events (AEs). RESULTS AND DISCUSSION We included six RCTs that contained 2,447 patients receiving induction therapy with platinum-based combination therapies. The maintenance therapy Bev+Pem group had prolonged PFS (HR = 0.74, 95% CI 0.69-0.80, p < 0.00001) and OS (HR = 0.91, 95% CI 0.83-0.99, p = 0.02) compared with the Bev/Pem group. Moreover, we further analysed the PFS rate (PFSR) and OS rate (OSR) and found that the Bev+Pem group exhibited improved PFSR-0.5y, PFSR-1y, PFSR-1.5y, PFSR-2y and OS-2y, with preferable trends in OS-1y, OS-3y and OS-4y compared with the Bev/Pem single-agent maintenance therapy. In addition, subgroup analyses indicated that the Bev+Pem group had greater PFS and OS among patients aged <65 years, patients with an Eastern Cooperative Oncology Group (ECOG) score of 0, and patients who never smoked. Regarding adverse events (AEs), the Bev+Pem group exhibited an increased occurrence of anaemia, fatigue, thrombocytopenia and anorexia. WHAT IS NEW AND CONCLUSION For stage IIIB/IV nonsquamous NSCLC patients, maintenance therapy with Bev+Pem offers an increased survival outcome (PFS, OS) compared with monotherapy. However, the increased incidence of AEs should not be neglected.

Onco Targets Ther 2020; 13:3751-3763. [PMID: 32440144 PMCID: PMC7210034 DOI: 10.2147/ott.s242579] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Accepted: 04/07/2020] [Indexed: 12/21/2022] Open
Abstract
Purpose Alpha-1 antitrypsin (A1AT) is a secreted protein that plays an important role in various diseases. However, the role of A1AT in non-small cell lung cancer is obscure. Materials and Methods A1AT expression in non-small cell lung cancer was analyzed using quantitative reverse transcription PCR, Western blotting (WB), immunohistochemistry (IHC), and ELISA. WB and IF were used to analyze markers of epithelial-to-mesenchymal transition (EMT), EndoMT, and cancer stem cell (CSC). Transwell and cell wound healing assays were used to analyze migration and invasion abilities. Colony formation and CCK-8 assays were used to analyze cell proliferation following cisplatin treatment. Results A1AT expression was higher in lung cancer samples than in normal tissues and the increased expression was correlated with poor overall survival of patients. In vitro experiments showed that A1AT overexpressed by plasmid transfection significantly promoted migration, invasion, EMT, EndoMT, stemness, and colony formation in lung cancer cell lines, as opposed to A1AT downregulation by siRNA transfection, which significantly inhibited all these variables. Conclusion A1AT is a novel therapeutic target and might be associated with tumor metastasis in lung carcinoma.

Abstract
PURPOSE To investigate whether the vessels surrounding a nodule depicted on non-contrast, low-dose computed tomography (LDCT) can discriminate benign and malignant screen detected nodules. MATERIALS AND METHODS We collected a dataset consisting of LDCT scans acquired on 100 subjects from the Pittsburgh Lung Screening study (PLuSS). Fifty subjects were diagnosed with lung cancer and 50 subjects had suspicious nodules later proven benign. For the lung cancer cases, the location of the malignant nodule in the LDCT scans was known; while for the benign cases, the largest nodule in the LDCT scan was used in the analysis. A computer algorithm was developed to identify surrounding vessels and quantify the number and volume of vessels that were connected or near the nodule. A nonparametric receiver operating characteristic (ROC) analysis was performed based on a single nodule per subject to assess the discriminability of the surrounding vessels to provide a lung cancer diagnosis. Odds ratio (OR) were computed to determine the probability of a nodule being lung cancer based on the vessel features. RESULTS The areas under the ROC curves (AUCs) for vessel count and vessel volume were 0.722 (95% CI=0.616-0.811, p<0.01) and 0.676 (95% CI=0.565-0.772), respectively. The number of vessels attached to a nodule was significantly higher in the lung cancer group 9.7 (±9.6) compared to the non-lung cancer group 4.0 (±4.3) CONCLUSION: Our preliminary results showed that malignant nodules are often surrounded by more vessels compared to benign nodules, suggesting that the surrounding vessel characteristics could serve as lung cancer biomarker for indeterminate nodules detected during LDCT lung cancer screening using only the information collected during the initial visit.

Pemetrexed plus dendritic cells as second-line treatment for patients with stage IIIB/IV non-small cell lung cancer who had treatment with TKI. Med Oncol 2014; 31:63. [PMID: 24958515 DOI: 10.1007/s12032-014-0063-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2014] [Accepted: 05/30/2014] [Indexed: 10/25/2022]
Abstract
The aim of this study was to determine the efficacy and toxicity of pemetrexed plus dendritic cells (DCs) in patients suffering from stage IIIB or IV lung adenocarcinoma, who had undergone maintenance treatment with gefitinib or erlotinib. Patients who had failed gefitinib or erlotinib maintenance treatment had ECOG performance statuses ranging from 0 to 2.27 patients received pemetrexed plus DCs as second-line treatment. Dosage: 500 mg/m(2) pemetrexed was administered on day 1 of a 21-day cycle. DCs were given for one cycle of 21 days. Three patients (11.1 %) experienced a partial response and 14 patients (51.9 %) showed stable disease. Ten patients (37.0 %) had progressive disease. The median time to progression-free survival (PFS) was 4.8 months [95 % confidence interval (CI) 4.4-5.2], and the median overall survival was 10.7 months (95 % CI 10.3-11.2). In the subgroup analysis, PFS had a significant difference between the low ratio of CD4/CD8 and normal ratio of CD4/CD8, with 4.5 months (95 % CI 4.2-4.9) and 5.0 months (95 % CI 4.5-5.7), (Log Rank = 0.039), respectively. No one patient experienced grade 4 toxicity. A regimen of pemetrexed combined with DCs is marginally effective and well tolerated in patients with stage IIIB or IV lung adenocarcinoma who had received gefitinib or erlotinib first-line treatment.

Abstract
Maintenance therapy has emerged as a novel therapeutic paradigm for advanced non-small-cell lung cancer (NSCLC). Maintenance therapy that aims to sustain a clinically favorable state after first-line chemotherapy has two strategies. Switch maintenance therapy entails switching to a new and non-cross-resistant agent in an alternating or sequential manner, on completion of first-line chemotherapy. Continuous maintenance therapy keeps ongoing administration of a component of the current regimen after four to six cycles of chemotherapy, if there is a stable disease, or better response. Both maintenance therapies can be continued, until disease progression. The potential evidence regarding maintenance therapy includes providing the opportunity to receive additional treatment, through sustaining tumor shrinkage, and delayed emergence of tumor-related symptom. Thus far, debates over the parameters used to predict the effectiveness of maintenance therapy, financial burden, and uncertainty of improving the quality of life exist. Despite many debates, maintenance therapy, which is currently recommended, has been disclosed to be beneficial.

Are erlotinib and gefitinib interchangeable, opposite or complementary for non-small cell lung cancer treatment? Biological, pharmacological and clinical aspects. Crit Rev Oncol Hematol 2013; 89:300-13.

Abstract
Gefitinib and erlotinib are the two anti-epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) approved for treatment of advanced NSCLC patients. These drugs target one of the most important pathways in lung carcinogenesis and are able to exploit the phenomenon of 'oncogene addiction', with different efficacy according to EGFR gene mutational status in tumor samples. Gefitinib has been approved only for EGFR mutation bearing patients regardless the line of treatment, while erlotinib is also indicated in patients without EGFR mutation who undergo second- or third-line treatment. Some studies evaluated the main differences between these drugs both for direct comparison and to improve their sequential use. In particular, toxicity profile resulted partially different, and these observations may be explained by several molecular and pharmacokinetic features. Therefore, this review integrates preclinical data with clinical evidences of TKIs to guide the optimization of currently available treatments in advanced NSCLC patients.
