Abstract
Until recently, the standard treatment in unresectable stage III non-small cell lung cancer was concurrent chemoradiotherapy, but often with dismal outcome. The introduction of consolidation treatment with immune checkpoint inhibitors has shifted the treatment landscape and prognosis of these patients. However, patients whose tumors harbors an epidermal growth factor receptor (EGFR) mutation derived less benefit, with an increased risk of immune-related adverse events. Moreover, current data suggested that patients with oncogenic addicted tumors, mainly EGFR-positive tumors, and also anaplastic lymphoma kinase (ALK)-positive have poorer progression free survival after chemoradiotherapy. Indeed, these tumors have also inferior distant control compared with those who have wild-type disease, especially in the central nervous system, highlighting the need for assessing the role of targeted therapies in this patient population. It is speculated that outcome could probably increase with a consolidation treatment strategy including an EGFR tyrosine kinase inhibitor. However, a personalized treatment approach is not considered standard of care in this setting due to lack of robust evidence, as the majority of trials were performed in unselected patients, number of patients is limited and the majority of these studies were underpowered. In this review we summarize the role of tyrosine kinase inhibitors in unresectable stage III NSCLC, specifically focusing on EGFR-mutant tumors.

Abstract
Patients with early-stage non-small-cell lung cancer (NSCLC) are candidates for curative surgery; however, despite multiple advances in lung cancer management, recurrence rates remain high. Adjuvant chemotherapy has been demonstrated to significantly prolong overall survival (OS), but this benefit is modest and there is an urgent need for effective new therapies to provide a cure for more patients. The high efficacy of tyrosine kinase inhibitors (TKIs) against epidermal growth factor receptor-mutated (EGFR) in patients with advanced EGFR-mutated NSCLC has led to the evaluation of these agents in early stages of the disease. Multiple clinical trials have evaluated the safety and efficacy of EGFR TKIs as an adjuvant treatment, in patients with resected EGFR-mutated NSCLC, and shown that they significantly prolong disease-free survival (DFS), but this benefit does not translate to OS. Recently, an interim analysis of the ADAURA trial demonstrated that, surprisingly, osimertinib improved DFS. This led to the study being stopped early, leaving many unanswered questions about its potential effect on OS and its incorporation as a standard adjuvant treatment in this patient subgroup. These targeted agents are also being evaluated in locally-advanced disease, with promising results, although prospective studies with larger sample sizes are needed to confirm these results. In this article, we review the most relevant studies on the role of EGFR TKIs in the management of early-stage EGFR-mutated NSCLC.

[PMID: 34153652 PMCID: PMC8233144 DOI: 10.1016/j.esmoop.2021.100191] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 05/13/2021] [Accepted: 05/26/2021] [Indexed: 12/02/2022] Open
Abstract
Background The role of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) induction coupled with standard concurrent chemoradiotherapy (CRT) is unclear in unresectable, stage III, EGFR-mutant non-small-cell lung cancer (NSCLC). Therefore, a phase II trial was conducted to evaluate the efficacy and safety of gefitinib induction followed by CRT in this disease setting. Patients and methods Patients with unresectable, EGFR-mutant, stage III NSCLC were administered gefitinib monotherapy (250 mg/day) for 8 weeks. Subsequently, patients without disease progression during induction therapy were administered cisplatin and docetaxel (40 mg/m2 each) on days 1, 8, 29, and 36 with concurrent radiotherapy at a total dose of 60 Gy. The primary endpoint was the 2-year overall survival (OS) rate, which was hypothesized to reach 85%, with a threshold of the lower limit of 60%. Results Twenty patients (median age: 66 years; male/female: 9/11; histology: 20 adenocarcinoma; stage IIIA/IIIB: 9/11; and exon 19/21: 10/10) were enrolled. The 2-year OS rate was 90% (90% confidence interval: 71.4% to 96.8%), indicating that this trial met the primary objective. The overall response rate and 1- and 2-year progression-free survival rates were 85.0%, 58.1%, and 36.9%, respectively. Grade ≥3 adverse events (>10%) included hepatic toxicity during the induction phase and neutropenia and febrile neutropenia in the CRT phase. Radiation pneumonitis grade ≥3 or treatment-related death did not occur. Conclusions This is the first prospective study to demonstrate the favorable efficacy and safety of EGFR-TKI induction followed by standard CRT in EGFR-mutant, stage III NSCLC. Further confirmatory studies are needed. This is the first prospective study evaluating gefitinib induction followed by CRT in EGFR-mutated, locally advanced NSCLC. The 2-year OS rate was 90% (90% confidence interval: 71.4% to 96.8%), indicating that this trial met the primary objective. The objective response rate throughout the treatment protocol was 85.0% (17 of 20). The safety findings were consistent with the known safety profiles of all agents administered. Our results might raise a critical point that needs to be evaluated in further studies to improve the cure rate.

Abstract
The combination of radiotherapy (RT) with targeted agents in non-small cell lung cancer (NSCLC) has been expected to improve the therapeutic ratio and tumor control. The EGFR blockade enhances the antitumor effect of RT. The ALK inhibition elicits anti-proliferative, pro-apoptotic and antiangiogenic effects in ALK-positive NSCLC cell lines, enhanced by the exposure to RT. The antiangiogenic agents normalize pathological tumor vessels, thus decrease tumor cell hypoxia and improve radiosensitivity. To date, however, none of the targeted agents combined with RT has shown proven clinical benefit over standard chemoradiation (CRT) in locally advanced NSCLC. The risk of potential excessive toxicity related to the therapeutic combination of RT and targeted agents cannot be ignored. Well-designed clinical trials may allow development of more effective combination strategies. Another potential application of combined RT and targeted therapies in oncogene-driven NSCLC is metastatic oligoprogressive or oligopersistent disease. The use of RT in oligoprogressive oncogene-driven NSCLC, while continuing first line targeted therapy, can potentially eradicate resistant cell clones and provide survival benefit. Likewise, the consolidation of oligopersistent foci (molecularly resistant to first line targeted therapy) may potentially interfere with the natural course of the disease by avoiding or delaying progression. We discuss here the molecular and radiobiological mechanisms of combining RT and targeted agents, and summarize current clinical experience.

Abstract
The standard treatment of unresectable locally advanced non-small cell lung cancer (LA NSCLC) is concurrent chemoradiotherapy. With the addition of immunotherapy, patients with LA NSCLC received a significantly prolonged outcome, while patients with harboring epidermal growth factor receptor (EGFR) mutation benefited less. Tyrosine kinase inhibitors (TKIs) have revolutionized the treatment of stage IV with harboring EGFR mutation and anaplastic lymphoma kinase rearrangement, but there are few recommendations indicating whether TKI treatment is effective in unresectable NSCLC. Preclinical studies have shown that TKIs could have a radiosensitizing effect, which provided a rationale to consider the application TKI with radiotherapy. In this review, we summarize the clinical studies that have used TKIs in LA-NSCLC as well as ongoing trials, and discuss recent progress in research related to the efficacy of TKI for unresectable LA NSCLC patients. Recent results of small studies evaluating TKI therapy for LA NSCLC patients in combination with radiation or chemoradiation demonstrated promising efficacy, improved outcomes with a tolerable toxicity profile. However, there is a lack of strong evidence for TKI treatment in unresectable LA NSCLC, because of unpowered statistics, lack of molecular selection, or lack of large randomized arms. We prospect the combination of TKI and radiation or chemoradiation therapy might eventually replace the current standard treatment for patients with LA NSCLC harboring oncogene-driven mutation.

Abstract
Approximately 20-25% of non-small-cell lung cancer (NSCLC) is diagnosed when the disease has progressed to clinical stage III. At this stage, and even if the cancer is considered unresectable, the treatment strategy should aim to achieve a cure. At the time of the initial diagnosis, it is necessary for medical oncologists to devise the best treatment strategy for each patient by composing a multidisciplinary treatment team including thoracic surgeons and radiation oncologists. In this review, we summarize prior pivotal clinical trials in unresectable clinical stage III NSCLC. Furthermore, we review very recent clinical trials evaluating the efficacy of immune checkpoint inhibitors in the treatment of NSCLC.

Abstract
BACKGROUND Afatinib, a second-generation irreversible epidermal growth factor inhibitor receptor for the development of non-small cell lung cancer and secondary drug resistance, has low bioavailability and adverse reactions due to current oral administration. The aim of this study was to prepare a novel drug delivery system, afatinib liposome, and to establish a method for the determination of encapsulation efficiency. METHODS Four different preparation methods were used to prepare afatinib liposomes, and the optimal preparation process was determined by comparing the encapsulation efficiency and particle size. RESULTS It has been verified that sephadex microcolumn centrifugation can be used to purify afatinib liposomes, and UV spectrophotometry can be employed to determine the entrapment efficiency of liposomes. Among different preparation methods, the encapsulation efficiency of afatinib liposomes prepared by ammonium sulfate gradient method was 90.73% and the average particle size was 108.6 nm. CONCLUSIONS Ammonium sulfate gradient method can be successfully applied to prepare afatinib liposomes that performed higher encapsulation efficiency and smaller particle size. The UV spectrophotometry employed to determine the liposome encapsulation efficiency was easy operation and with high accuracy.

Abstract
INTRODUCTION Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have a pronounced clinical benefit for patients with advanced non-small cell lung cancer (NSCLC) positive for EGFR activating mutations. Such individuals inevitably develop resistance to these drugs, however, new treatment strategies to overcome such resistance are being actively pursued. The clinical benefit of EGFR-TKIs for patients with locally advanced NSCLC remains to be clarified. Areas covered: This review summarizes the recent progress in combination treatment with EGFR-TKIs and either chemotherapy or radiotherapy for patients with NSCLC positive for EGFR activating mutations. Expert commentary: Combination therapy with EGFR-TKIs and various other treatment options are under investigation in clinical studies. Although early studies failed to show a clinical benefit for such combination therapy because of a lack of patient selection, clinical studies with patient selection based on EGFR mutation status have shown promising results. Such combination therapy might eventually replace the current standard treatment for patients with NSCLC positive for EGFR activating mutations.

Abstract
Epidermal growth factor receptor (EGFR) is an essential regulator and biomarker of several types of cancer. However, the association between its expression and prognosis in patients with resected T3 stage gastric adenocarcinoma (RT3-GA) remains to be determined. In total, 683 patients with resectable T3-GA who underwent surgery were retrospectively included in the present study, and their immunohistochemical data for EGFR expression were collected. The associations between the patients' clinicopathologic characteristics and EGFR immunohistochemistry data were analyzed by multiple statistical methods. Annexin V apoptosis and MTT cell viability assays were performed to explore the effect of EGFR on AGS gastric adenocarcinoma cell survival. EGFR expression levels were categorized into two groups: low (406 cases) and high (277 cases). High EGFR was demonstrated to be significantly associated with distant metastasis (P=0.043) and severely decreased median overall survival time (MOST) and recurrence-free survival time (MRFST). MOST and MRFST in the low EGFR group were 39 and 37 months, respectively; whereas in the high EGFR group these values were only 18 and 13 months (P=3.10×10-9 and P=6.74×10-8, respectively). Multivariate analysis confirmed that high EGFR expression levels were associated with poor survival, which was associated with significantly increased recurrence risk and ~2-fold elevation in mortality risk [hazard ratio (HR), 1.73; 95% confidence interval (CI), 1.43-2.10; P=2.37×10-8 and HR, 1.80; 95% CI, 1.50-2.17; P=3.80×10-10]. Inhibiting EGFR with AG1478 suppressed its effect on promoting AGS cell survival. These results suggest that high EGFR expression indicates poor survival in patients with RT3-GA, which may be correlated with EGFR promoting GA cell survival.

Abstract
Neoadjuvant Chemotherapy has been used for the stage III of non-small cell lung cancer (NSCLC) and has shown good clinical effects. However, the survival benefits of radiation therapy added in induction regimens remains controversial. We therefore conducted a meta-analysis of the published clinical trials to quantitatively evaluate the benefit of preoperative chemoradiotherapy. After searching the database of Pubmed, CNKI, EMBASE, ESMO, The Cochrane Library databases, The American Society of Clinical Oncology and Clinical Trials.gov. Trials were selected for meta-analysis if they provided an independent assessment of neoadjuvant chemoradiation and neoadjuvant chemotherapy, odds ratio(OR) for tumor downstaging, mediastinal lymph nodes pathological complete response and local control, hazard ratios (HRs) for 5-year survival and progression-free survival were pooled by the stata software version 12.0. Twelve studies involving 2,724 patients were identified, tumor downstaging (p = 0.01), mediastinal lymph nodes pathological complete responses (p = 0.028) and local control (P = 0.002) were achieved, when compared with neoadjuvant chemotherapy. The meta-analysis demonstrated neither 5-year survival nor progression-free-survival benefit in survival from adding radiation. In conclusion, the addition of radiotherapy into chemotherapy was not superior to neoadjuvant chemotherapy. The higher quality of trials need be investigated combining with the histopathological type and genotyping of lung cancer by clinicians.
