Comparing Gefitinib and Traditional Chemotherapy for Better Survival in Patients With Non-Small Cell Lung Cancer: A Systematic Review. Cureus 2023; 15:e33691. [PMID: 36788891 PMCID: PMC9921039 DOI: 10.7759/cureus.33691] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 12/07/2022] [Indexed: 01/15/2023] Open
Abstract
Current non-small cell lung cancer (NSCLC) treatment consists of various combinations of surgery, chemotherapy, and/or radiation, depending on the tumor stage. Individuals with stage II-IIIa NSCLC undergo surgery, followed by combination chemotherapy containing cisplatin, such as vinorelbine + cisplatin. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), such as gefitinib, act by inhibiting any signaling pathway containing the EGFR mutation and inhibiting the growth of NSCLC. TKI is a treatment option in advanced NSCLC, resulting in more prolonged progression-free survival (PFS). This manuscript aims to evaluate the influence of utilizing gefitinib - either alone or in combination with conventional chemotherapeutic drug regimens upon NSCLC patient profile survival parameters. A systematic literature review was conducted across multiple scientific literature repositories. The review was performed using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020. There were six randomized clinical trials (RCT) and five retrospective studies. The overall consensus based on the end outcome of each published journal on the effectiveness of gefitinib as a treatment option for NSCLC indicated that there was a notable difference in overall survival (OS) and progression-free survival (PFS) and disease-free survival (DFS) datasets. Gefitinib use correlated with increased timeframes for multiple patient survival parameters within articles shortlisted in this investigation. However, more comprehensive investigations are required to validate such correlations. Gefitinib did demonstrate the potential to provide beneficial effects and counteract NSCLC within such patients.

Durable response to afatinib rechallenge in a long-term survivor of non-small cell lung cancer harboring EGFR L858R and L747V mutations. Thorac Cancer 2022; 13:3225-3228. [PMID: 36193787 PMCID: PMC9663673 DOI: 10.1111/1759-7714.14678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 09/16/2022] [Accepted: 09/17/2022] [Indexed: 01/07/2023] Open
Abstract
Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors are standard therapeutic agents for non-small cell lung cancer (NSCLC) patients with major EGFR mutations such as exon 19 deletions and a L858R mutation, whereas treatment strategies for cases with uncommon EGFR mutations remain to be fully established. Here, we report a long-term (≥20 years from initial diagnosis) NSCLC survivor carrying EGFR L858R and L747V mutations. The patient received gefitinib monotherapy, systemic chemotherapy/chemoimmunotherapy, and local consolidative therapies for oligometastatic lesions, and responded to afatinib rechallenge with a progression-free survival of 12 months. The current case suggests that afatinib is effective in NSCLC patients with EGFR L858R and L747V mutations and that a therapeutic approach combining appropriately timed systemic therapies with local consolidative therapies for oligometastatic lesions improves long-term survival.

Application Value of Serum Multi-Antibody Combined Detection in Differential Diagnosis and Typing of Lung Cancer. JOURNAL OF ONCOLOGY 2022; 2022:8944263. [PMID: 35126518 PMCID: PMC8816536 DOI: 10.1155/2022/8944263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 11/13/2021] [Accepted: 11/26/2021] [Indexed: 11/18/2022]
Abstract
One of the most prevalent malignant tumours is lung cancer. Circulating microRNAs (miRNAs) have shown to have significant promise for lung cancer diagnosis and prognosis, according to a growing body of research. The researchers wanted to explore if serum exosomal miR-1246 has any treatment significance in patients with non-small-cell lung cancer (NON-SCLC). Real-time PCR was used to determine the stage of exosomal miR-1246 serum expression in NON-SCLC patients. The researchers next looked into the link regarding exosomal miR-1246 serum stages and NON-SCLC prognosis. In NON-SCLC patients, exosomal miR-1246 serum appearance was considerably higher. According to a receiver operating characteristic (ROC) research, serum exosomal miR-1246 was effective in discriminating NON-SCLC patients from normal controls and non-malignant respiratory illness patients. Following treatment, the amount of serum exosomal miR-1246 reduced but increased in cases of recurrence. Furthermore, the level of serum exosomal miR-1246 was connected to distant metastases and TNM stages in a significant way. According to a survival analysis, cases with severe levels of exosomal miR-1246 serum had reduced overall or disease-free survival. The level of exosomal miR-1246 serum was found to be an autonomous predictive issue for NON-SCLC in multi-variate analysis. Finally, exosomal miR-1246 serum may be a useful prognosis biomarker for non-small-cell lung cancer.

Risk Factors for Short-Term Lung Cancer Survival. J Clin Med 2021; 10:jcm10030519. [PMID: 33535673 PMCID: PMC7867142 DOI: 10.3390/jcm10030519] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Revised: 01/13/2021] [Accepted: 01/26/2021] [Indexed: 12/25/2022] Open
Abstract
Background: Lung cancer is typically diagnosed in an advanced phase of its natural history. Explanatory models based on epidemiological and clinical variables provide an approximation of patient survival less than one year using information extracted from the case history only, whereas models involving therapeutic variables must confirm that any treatment applied is worse than surgery in survival terms. Models for classifying less than one year survival for patients diagnosed with lung cancer which are able to identify risk factors and quantify their effect for prognosis are analyzed. Method: Two stepwise binary logistic regression models, based on a retrospective study of 521 cases of patients diagnosed with lung cancer in the Interventional Pneumology Unit at the Hospital “Virgen de las Nieves”, Granada, Spain. Results: The first model included variables age, history of pulmonary neoplasm, tumor location, dyspnea, dysphonia, and chest pain. The independent risk factors age greater than 70 years, a peripheral location, dyspnea and dysphonia were significant. For the second model, treatments were also significant. Conclusions: Age, history of pulmonary neoplasm, tumor location, dyspnea, dysphonia, and chest pain are predictors for survival in patients diagnosed with lung cancer at the time of diagnosis. The treatment applied is significant for classifying less than one year survival time which confirms that any treatment is markedly inferior to surgery in terms of survival. This allows to consider applications of more or less aggressive treatments, anticipation of palliative cares or comfort measures, inclusion in clinical trials, etc.

Abstract
Eukaryotic translation initiation factor 4 gamma 1 (EIF4G1), as the key component of the transcription initiation factor complex EIF4F, is significantly upregulated in multiple solid tumours, including lung cancer. However, the function and mechanism of EIF4G1 in the regulation of non‐small‐cell lung cancer (NSCLC) remain unclear. Here, using the clinical samples and the comprehensive survival analysis platforms Kaplan‐Meier plotter, we observed aberrant upregulation of EIF4G1 in NSCLC tissues; furthermore, high expression of EIF4G1 showed association with low differentiation of lung cancer cells and poor overall survival in NSCLC patients. Non‐small‐cell lung cancer cell line A549 and H1703 stably infected with EIF4G1 shRNA were used to determine the function of EIF4G1 in regulating cell proliferation and tumorigenesis in vitro and in vivo. The results demonstrated that EIF4G1 promoted the G1/S transition of the cell cycle and tumour cell proliferation in non‐small cell lung cancer. Mechanistically, EIF4G1 was found to regulate the expression and phosphorylation of mTOR (Ser2448), which mediates the tumorigenesis‐promoting function of EIF4G1. The inhibition of mTOR attenuated the EIF4G1‐induced development and progression of tumours. These findings demonstrated that EIF4G1 is a new potential molecular target for the clinical treatment of non‐small cell lung cancer.

Abstract
Tight junction protein 1 (TJP1) is a membrane-associated cytosolic protein important for cell-cell communication in intercellular barriers in epithelial and non-epithelial cells. Here, we explored the functional involvement of TJP1 in non-epithelial tumors such as soft tissue sarcoma, especially in leiomyosarcoma (LMS). TJP1 expression in soft tissue sarcoma was analyzed in normal and tumor tissues as well as from public datasets such as the TCGA provisional dataset, in which TJP1 expression was compared with other subtypes such as undifferentiated sarcomas, and myxofibrosarcomas. SK-LMS-1 cell lines with reduced TJP1 expression showed attenuated anchorage-independent colony formation as well as reduced intercellular aggregation on non-coated culture plates compared with control as well as parental SK-LMS-1 cells. Transcriptome profiling following TJP1 knockdown in SK-LMS-1 cells suggested the involvement of several signaling pathways, including NF-κB pathway and growth factor receptor signaling. In addition, TJP1 downregulation induced enhanced response against anti-cancer agents, doxorubicin and gefitinib. Taken together, these results suggest that TJP1 contributes to sarcoma genesis and might be useful therapeutic target. KEY MESSAGES: • TJP1 expression at RNA level higher in tumor than in normal tissues of sarcoma. • Targeting TJP1 attenuates cell-cell aggregation and anchorage-independent growth. • Targeting TJP1 is beneficial in anti-cancer therapy in LMS.

Abstract
Background Lung cancer is a global health problem with a high mortality, and the development of target therapy has led to a revolution in the treatment of lung cancer in recent years. Favorable efficacy and safety of icotinib have been demonstrated in patients with non-small cell lung cancer (NSCLC). Currently, minimal data are available to describe the long-term safety of icotinib in NSCLC patients. Methods We reviewed the safety data from 1,321 advanced NSCLC patients who were treated with icotinib. The primary endpoint was the long-term safety, defined as any adverse drug reactions (ADRs) occurred after 6 months of icotinib administration. Results Fewer ADRs were noticed over 6 month administration of icotinib than within 6 months in overall population (24.3% vs. 65.4%), and elderly patients (23.6% vs. 66.9%). The majority of ADRs were grade 1–2 in severity over 6 month exposure of icotinib in overall population as well as elderly patients. In overall population, the most common ADRs of icotinib during long-term use were rash (16.4%) and diarrhea (5.3%), while the incidences were 31.8% and 13.2% in the induction period, respectively. In elderly population, the most common ADRs of icotinib during long-term use were rash (15.7%) and diarrhea (4.7%), while the incidences were 27.8% and 14.9% in the induction period, respectively, and more inching was observed in the induction period as compared with long term use (6.3% vs. 0.3%). Conclusions There was an evidence of decreased frequency of icotinib-induced ADRs over time, and icotinib was well-tolerated in elderly NSCLC patients.

Abstract
The secreted frizzled‑related protein 2 (SFRP2) has been reported to inhibit non‑small cell lung cancer (NSCLC) cell survival and metastasis; however, the underlying mechanisms are yet to be fully determined. The present study focused on mitochondrial fission and the Wnt signaling pathway. The results demonstrated that SFRP2 was downregulated in the NSCLC cell line A549 compared with in a normal pulmonary epithelial cell line using western blotting, reverse transcription‑quantitative PCR and immunofluorescence. Subsequently, it was demonstrated that SFRP2 overexpression promoted the apoptosis, and inhibited the proliferation and metastasis of A549 cells using MTT assays, TUNEL staining and 5‑ethynyl‑2'‑deoxyuridine labeling. At the molecular level, the overexpression of SFRP2 in A549 cells led to the activation of mitochondrial fission by inhibiting the Wnt signal pathway. Excessive mitochondrial fission induced low ATP generation, impaired mitochondrial respiratory function, induced mitochondrial potential depolarization, and increased mitochondrial permeability transition pore opening, and imbalances in pro‑ and antiapoptotic protein expression. Furthermore, mitochondrial fission was involved in the inhibition of A549 cell proliferation and metastasis. Thus, SFRP2 may inhibit the survival and metastasis of NSCLC cells via the Wnt/mitochondrial fission pathway.

Abstract
BACKGROUND Apatinib is an oral small-molecule tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2 (VEGFR-2). Some clinical trials have demonstrated that apatinib is efficacious against advanced nonsquamous NSCLC. OBJECTIVE This study aimed to probe efficacy and safety of apatinib plus docetaxel, as the second or above line treatment, in advanced nonsquamous NSCLC. DESIGN Multicenter, prospective, single arm study. SETTING Three teaching hospitals centers in the Sichuan. PARTICIPANTS Fourteen patients with stage IVA/B nonsquamous NSCLC had previously received at least 1 platinum-based chemotherapy regimen. INTERVENTION Patients who were enrolled between November 2016 and January 2018 were given docetaxel (75 mg/m, i.v., d1) plus oral apatinib (250 mg/d), 4 weeks as one cycle, until disease progression or intolerance to adverse events (AE). MAIN OUTCOME MEASURES The primary endpoint was progression-free survival (PFS). The secondary endpoints comprised objective response rate (ORR), disease control rate (DCR), overall survival (OS), and AE incidence rate. RESULTS All patients carried adenocarcinoma by pathological type. The median follow-up duration was 9.76 months. Out of 14 cases, 12 were evaluable, showing ORR of 33.33%, DCR of 66.67%, DCR of 50% in cases with brain metastasis, median PFS of 2.92 months (95% CI: 1.38-4.48), and 6-month OS of 80%. Primary AEs encompassed: leukopenia in 7 cases (58.33%), hand-foot skin reaction in 5 cases (41.67%), and diarrhea in 4 cases (33.33%). Among them, grade 3 AEs were: leukopenia in 4 cases (33.33%), and hand-foot skin reaction in 1 case (8.33%). No grade 4/5 AEs were reported. Univariate and multivariate analysis were conducted respectively for PFS and OS. These factors encompassed: gender, age, gene mutations, clinical stage, ECOG scores, quantity of metastatic foci, brain metastasis, and hand-foot skin reaction. Results demonstrated zero risk factors for PFS or OS. CONCLUSION Apatinib plus docetaxel, as the second or above line treatment, is effective and safe against advanced nonsquamous NSCLC, with good tolerance profile. TRIAL REGISTRATION NCT03416231.

First-line afatinib for advanced EGFRm+ NSCLC: Analysis of long-term responders in the LUX-Lung 3, 6, and 7 trials. Lung Cancer 2019; 133:10-19. [PMID: 31200814 DOI: 10.1016/j.lungcan.2019.04.006] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 04/04/2019] [Accepted: 04/06/2019] [Indexed: 02/07/2023]
Abstract
OBJECTIVES In patients with advanced epidermal growth factor receptor mutation-positive (EGFRm+) non-small cell lung cancer (NSCLC), first-line afatinib significantly improved progression-free survival (PFS) and objective response vs. platinum-doublet chemotherapy in the phase III LUX-Lung 3 and LUX-Lung 6 trials, and significantly improved PFS, time to treatment failure and objective response vs. gefitinib in the phase IIb LUX-Lung 7 trial. We report post-hoc analyses of efficacy, safety and patient-reported outcomes (PROs) in afatinib long-term responders (LTRs) in these trials. METHODS Treatment-naïve patients with stage IIIB/IV EGFRm + NSCLC randomized to afatinib in LUX-Lung 3/LUX-Lung 6/LUX-Lung 7 were included in the analysis. Patients treated with afatinib for ≥ 3 years were defined as LTRs. RESULTS In LUX-Lung 3, LUX-Lung 6, and LUX-Lung 7, 24/229 (10%), 23/239 (10%) and 19/160 (12%) afatinib-treated patients were LTRs. Baseline characteristics were similar to the study populations, except for the proportions of women (LUX-Lung 3/LUX-Lung 6 only; 92/78% vs. 64% overall) and Del19-positive patients (63-79% vs. 49-58% overall). Median treatment duration among LTRs was 50, 56 and 42 months, and median PFS was 49.5, 55.5, and 42.2 months in LUX-Lung 3/LUX-Lung 6/LUX-Lung 7, respectively. Median overall survival could not be estimated. Frequency of afatinib dose reduction was consistent with the LUX-Lung 3/LUX-Lung 6/LUX-Lung 7 overall populations. PROs were stable in LTRs, with slight improvements after 3 years of afatinib treatment vs. baseline scores. CONCLUSIONS In the LUX-Lung 3/LUX-Lung 6/LUX-Lung 7 trials, 10-12% of afatinib-treated patients were LTRs. Long-term afatinib treatment was independent of tolerability-guided dose adjustment and had no detrimental impact on safety or PROs.

Abstract
INTRODUCTION Despite advances in treatment, head and neck squamous cell carcinoma (HNSCC) survival rates remain stagnant. Current treatment is associated with significant toxicities and includes chemotherapy, radiation, surgery, and few targeted treatments. Targeted treatments, epidermal growth factor receptor (EGFR)-targeted agent, cetuximab, and immune checkpoint inhibitors, pembrolizumab and nivolumab, show improved toxicity profiles and modestly improved survival in select patients. An urgent need remains to identify novel targeted treatments for single-agent or combined therapy use. AREAS COVERED Multitargeted kinase inhibitors are small molecule inhibitors with limited toxicity. This review will focus on early-stage investigations of multitargeted tyrosine kinase inhibitors (m-TKIs) (those that target at least two tyrosine kinases) for HNSCC. Preclinical and early trials investigating m-TKIs for various disease settings of HNSCC will be evaluated for efficacy, identification of significant biomarkers and potential for combination therapy. EXPERT OPINION Few single agent m-TKIs have demonstrated efficacy in unselected HNSCC populations. The most promising clinical results have been obtained when m-TKIs are tested in combination with other therapies, including immunotherapy, or in mutation-defined subgroups of patients. The future success of m-TKIs will rely on identification, in preclinical models and clinical trials, of predictive biomarkers of response and mechanisms of innate and acquired resistance.
