Wu LL, Jiang WM, Qian JY, Tian JY, Li ZX, Li K, Ma GW, Xie D, Chen C. High-risk characteristics of pathological stage I lung adenocarcinoma after resection: patients for whom adjuvant chemotherapy should be performed. Heliyon 2023; 9:e23207. [PMID: 38144332 PMCID: PMC10746451 DOI: 10.1016/j.heliyon.2023.e23207] [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: 12/30/2022] [Revised: 11/26/2023] [Accepted: 11/29/2023] [Indexed: 12/26/2023] Open
Abstract
Background The objective of the present study was to identify patients with pathologic stage I lung adenocarcinoma (LUAD) who are at high risk of recurrence and assess the efficacy of adjuvant chemotherapy (ACT) in these individuals. Methods A retrospective study was conducted on 1504 patients with pathologic stage I LUAD who underwent surgical resection at Shanghai Pulmonary Hospital and Sun Yat-sen University Cancer Center. Cox proportional hazard regression analyses were performed to identify indicators associated with a high risk of recurrence, while the Kaplan-Meier method and Log-rank test were employed to compare recurrence-free survival (RFS) and overall survival (OS) between patients with ACT and those without it. Results Four independent indicators, including age (≥62 years), visceral pleural invasion (VPI), predominant pattern (micropapillary/solid), and lymphovascular invasion (LVI), were identified to be significantly related with RFS. Subsequently, patients were classified into high-risk and low-risk groups by LVI, VPI, and predominant pattern. The administration of ACT significantly increased both RFS (P < 0.001) and OS (P = 0.03) in the high-risk group (n = 250). Conversely, no significant difference was observed in either RFS (P = 0.45) or OS (P = 0.063) between ACT and non-ACT patients in the low-risk group (n = 1254). Conclusions Postoperative patients with stage I LUAD with factors such as LVI, VPI, and micropapillary/solid predominant pattern may benefit from ACT.

Long-term follow-up of a consecutive cohort validating an epidermal growth factor receptor mutation as an independent risk factor for postoperative recurrence in lung adenocarcinoma. INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2023; 37:ivad174. [PMID: 37930012 PMCID: PMC10640389 DOI: 10.1093/icvts/ivad174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 10/09/2023] [Accepted: 10/29/2023] [Indexed: 11/07/2023]
Abstract
OBJECTIVES Third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors were recently reported to be effective as adjuvant therapy for resected lung adenocarcinoma (ADC) harbouring common EGFR mutations. However, whether the EGFR mutation is a direct risk factor for postoperative recurrence remains unknown. Therefore, we conducted a multi-institutional observational study to compare postoperative survival according to EGFR mutation status. METHODS We collected the medical records of consecutive patients who underwent surgical resection for ADC between 2005 and 2012 at 4 participating institutions. Recurrence-free survival (RFS) and overall survival (OS) associated with EGFR mutation status were evaluated. We further analysed survival after pair-matching patients' clinicopathological characteristics. RESULTS EGFR mutations were harboured by 401 of 840 (48%) enrolled patients. The number of patients with an EGFR mutation (M group) differed from that with the EGFR wild-type sequence (W group) in terms of sex, smoking history and pathological stage. The median follow-up period was 85 months. The five-year RFS/OS rates of the M and W groups were 70%/85% and 61%/75%, respectively (P < 0.001 for both groups). However, multivariable analysis revealed that EGFR mutation status was not independently related with both RFS and OS. In pair-matched analysis, the RFS and OS curves of the patients with an EGFR mutation and wild-type sequence were not statistically different, either. CONCLUSIONS Long-term follow-up of consecutive patients did not show that a common EGFR mutation was an independent risk factor of recurrence or prognostic factor for completely resected lung ADC.

Lung Cancer 2023; 184:107354. [PMID: 37634262 DOI: 10.1016/j.lungcan.2023.107354] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 07/05/2023] [Accepted: 08/21/2023] [Indexed: 08/29/2023]
Abstract
OBJECTIVE Clinical T factors in the 8th TNM classification of lung cancer have a practical problem. In some cases, it is difficult to measure the size of the solid components in part-solid tumors, and the classification of these tumors is controversial. METHODS We evaluated 590 resected cT1N0M0 stage IA non-small-cell lung cancers based on the 7th edition between 2009 and 2012. Tumor and solid component diameters were measured using thin-section computed tomography (CT). We defined tumors with difficulty in measuring the size of the solid components as lung cancers with scattered or mixed consolidation (LCSMCs). LCSMCs were observed in 79 (13.4%) patients. Other tumors were classified as cTis, cT1mi, cT1a, cT1b, and cT1c, according to the 8th edition. We compared prognosis and epidermal growth factor receptor mutations (EGFRm) status of LCSMCs with those of cT1a, cT1b, and cT1c. RESULTS The difference in overall survival (OS) among cT1a, cT1b, and cT1c was significant (5-year-OS: 96.9% vs. 76.8% vs. 65.0%). There was no significant difference in prognosis between LCSCs and cT1a (5-year-OS: 92.4% vs. 96.9%). A significant difference was observed in the frequency of EGFRm between cT1a, cT1b, and cT1c (52.4%, 42.4%, and 29.8%). The incidence of EGFRm in LCSMCs was 54.8% and there was no significant difference between LCSMCs and cT1a. CONCLUSIONS The prognosis and frequency of EGFRm in LCSMCs were close to those in cT1a. As we cannot measure the diameter of the solid component in subsolid lung cancers, it may be appropriate to classify these tumors as cT1a tumors.

Abstract
PURPOSE Approximately, 45-65% stage I non-small cell lung cancer (NSCLC) patients with surgical resection relapse within 5 years. Therefore, it is urgent to identify the predictors involved in the relapse of stage I NSCLC. METHODS/PATIENTS Targeted sequencing was used to examine the mutation of tumor tissues and matched adjacent normal tissues from 35 patients with stage I lung adenocarcinoma (LUAD). Then, tissue microarrays containing tumor tissues from 149 stage I LUAD patients were used to assess protein expression of frequently mutated genes by immunohistochemistry. COX regression model was used to evaluate the impacts of frequently mutated genes and their protein expression on relapse-free survival (RFS) in stage I LUAD. RESULTS AND CONCLUSIONS Three hundred and twenty-nine non-synonymous somatic variants were identified in 161 genes among these 35 patients. EGFR, TP53, LRP1B, RBM10, KRAS, NTRK3, RB1, ALK, APC, FAT2, KEAP1, MED12 and MLL3 were described as frequently mutated genes with prevalence more than 10%. Patients harboring KRAS mutation had more relapse in 1 year after surgical resection. For the expression of these frequently mutated genes in 149 stage I patients, multivariate Cox regression analyses showed that the expression of RBM10 was positively associated with RFS in all patients (HR 0.40, 95% CI 0.15-1.0, p = 0.052), and the expression of APC was negative associated with RFS in patients with EGFR mutations (HR 3.10, 95% CI 1.54-6.26, p = 0.002). Stage I LUAD patients with KRAS mutation or low RBM10 expression are inclined to receive more positive intervention rather than just disease surveillance.

Abstract
INTRODUCTION This study evaluated the clinicopathologic characteristics and prognostic impact of atypical epidermal growth factor receptor (EGFR) mutations in patients with completely resected lung adenocarcinoma (LUAD) and investigate whether adjuvant chemotherapy could benefit the survival outcomes for these subjects. MATERIAL AND METHODS We retrospectively reviewed resected LUAD samples from 8437 patients and identified 5358 EGFR-mutated (EGFRm) cases. Of these, 4847 had classical mutations, while 511 had atypical mutations. For further survival analysis, propensity score matching, Kaplan-Meier curve, and Cox regression analyses were conducted. RESULTS Of the 511 patients with atypical EGFRm LUAD, 131 patients had compound mutations. The frequency of exon 20 insertion (20-ins), G719X, L861Q, S768I, and de novo T790M were 30.3%, 32.7%, 21.9%, 9.2%, and 11.4%, respectively. These patients included a higher proportion of males than those with classical EGFRm LUAD. Between the 483 matched pairs of the classical and atypical EGFRm patients, no significant difference emerged in disease-free survival (DFS) (p = 0.476). Patients with the L861Q mutation had the poorest DFS among those with atypical EGFRm LUAD (p = 0.005). Cox regression analyses revealed that the L861Q mutation was an independent prognostic factor for DFS in 487 patients with solely atypical EGFRm LUAD. In addition, adjuvant chemotherapy did not improve the DFS for those patients, whether in stage IB (p = 0.638) or II-III (p = 0.505) of the disease. CONCLUSION The L861Q mutation is an independent prognostic factor for DFS in patients with atypical EGFRm LUAD after complete resection who would not benefit from adjuvant chemotherapy regardless of disease stage.

Abstract
Background Activating mutations in the tyrosine kinase domain of epidermal growth factor receptor (EGFR) are predictive biomarkers for response to EGFR–tyrosine kinase inhibitor (TKI) therapy in lung adenocarcinoma (LUAD). Here, we characterized the clinicopathologic features associated with EGFR mutations via peptide nucleic acid clamping-assisted fluorescence melting curve analysis (PANAMutyper) and evaluated the feasibility of targeted deep sequencing for detecting the mutations. Methods We examined EGFR mutations in exons 18 through 21 for 2,088 LUADs from July 2017 to April 2020 using PANAMutyper. Of these, we performed targeted deep sequencing in 73 patients and evaluated EGFR-mutation status and TKI clinical response. Results EGFR mutation was identified in 55.7% of LUADs by PANAMutyper, with mutation rates higher in females (69.3%) and never smokers (67.1%) and highest in the age range of 50 to 59 years (64.9%). For the 73 patients evaluated using both methods, next-generation sequencing (NGS) identified EGFR mutation–positive results in 14 of 61 patients (23.0%) who were EGFR-negative according to PANAMutyper testing. Of the 10 patients reportedly harboring a sensitizing mutation according to NGS, seven received TKI treatment, with all showing partial response or stable disease. In the 12 PANAMutyper-positive cases, NGS identified two additional mutations in exon 18, whereas a discordant negative result was observed in two cases. Conclusions Although PANAMutyper identified high frequencies of EGFR mutations, targeted deep sequencing revealed additional uncommon EGFR mutations. These findings suggested that appropriate use of NGS may benefit LUAD patients with otherwise negative screening test results.

Prognostic impact of pretreatment T790M mutation on outcomes for patients with resected, EGFR-mutated, non-small cell lung cancer. BMC Cancer 2022; 22:775. [PMID: 35840951 PMCID: PMC9288048 DOI: 10.1186/s12885-022-09869-7] [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: 05/09/2022] [Accepted: 07/08/2022] [Indexed: 11/20/2022] Open
Abstract
Background Many previous studies have demonstrated that minor-frequency pretreatment T790M mutation (preT790M) could be detected by ultrasensitive methods in a considerable number of treatment-naïve, epidermal growth factor receptor (EGFR)-mutated, non-small cell lung cancer (NSCLC) cases. However, the impact of preT790M in resected cases on prognosis remains unclear. Methods We previously reported that preT790M could be detected in 298 (79.9%) of 373 surgically resected, EGFR-mutated NSCLC patients. Therefore, we investigated the impact of preT790M on recurrence-free survival (RFS) and overall survival (OS) in this cohort by multivariate analysis. All patients were enrolled from July 2012 to December 2013, with follow-up until November 30, 2017. Results The median follow-up time was 48.6 months. Using a cutoff value of the median preT790M allele frequency, the high-preT790M group (n = 151) had significantly shorter RFS (hazard ratio [HR] = 1.51, 95% confidence interval [CI]: 1.01–2.25, P = 0.045) and a tendency for a shorter OS (HR = 1.87, 95% CI: 0.99–3.55, P = 0.055) than the low-preT790M group (n = 222). On multivariate analysis, higher preT790M was independently associated with shorter RFS (high vs low, HR = 1.56, 95% CI: 1.03–2.36, P = 0.035), irrespective of advanced stage, older age, and male sex, and was also associated with shorter OS (high vs low, HR = 2.16, 95% CI: 1.11–4.20, P = 0.024) irrespective of advanced stage, older age, EGFR mutation subtype, and history of adjuvant chemotherapy. Conclusions Minor-frequency, especially high-abundance of, preT790M was an independent factor associated with a poor prognosis in patients with surgically resected, EGFR-mutated NSCLC.

Abstract
Introduction The adjuvant treatment of patients with resected lung adenocarcinoma (LUAD) remains unstandardized. We analyzed the survival outcomes of these patients based on EGFR mutation status and adjuvant chemotherapy treatment. Methods This noninterventional real-world study (ICAN) enrolled Chinese patients with resected stages I to III LUAD from April 8, 2010, to December 31, 2010. Tumor EGFR mutation status and 3-year disease-free survival (DFS) were determined. The extension phase provided long-term follow-up with overall survival (OS) as the primary end point. Secondary end points included DFS and prognostic factors of survival. Survival outcomes based on adjuvant chemotherapy treatment, EGFR mutation status, and postoperative stage were analyzed post hoc. Results Among 568 patients in the ICAN cohort, 472 continued to the extension phase and remained eligible. The 3-year DFS rate was 58.8%. In the extension cohort, 260 patients (55.1%) had EGFR-mutant disease and 207 (43.9%) received adjuvant chemotherapy. At a median follow-up of 109.0 (95% confidence interval [CI]: 106.6–111.4) months, median OS and DFS were 103.3 (95% CI: 101.7–104.9) and 67.4 (95% CI: 49.7–85.2) months, respectively. The 5-year OS and DFS rates were 68.9% (95% CI: 64.3–73.6) and 52.9% (95% CI: 48.2–57.7), respectively. EGFR wild-type disease was a significant independent predictor of worse OS (HR = 1.24, 95% CI: 1.07–1.44, p= 0.004) based on the Cox regression analysis of common factors. Post hoc subgroup analysis revealed that survival outcomes were not significantly different with adjuvant chemotherapy regardless of EGFR mutation status across all postoperative stages. Conclusions EGFR mutations are common in operable LUAD, and recurrence and mortality after resection were considerable. Adjuvant chemotherapy did not improve survival outcomes, regardless of EGFR mutation status and postoperative stage.

Abstract
Background Reinvigoration of T-cell exhaustion with antibodies has shown promising efficacy in patients with non-small-cell lung cancer (NSCLC). However, the characteristics of T-cell exhaustion with regard to tumor-infiltrating lymphocytes (TILs) are poorly elucidated in NSCLC. Here, we investigated the exhaustion status of TILs in NSCLC patients at the intraindividual and interindividual levels. Methods We obtained paired peripheral blood, normal adjacent tissues, peritumoral tissues, and tumor tissues from 96 NSCLC patients. Features of T-cell exhaustion were analyzed by flow cytometry. T cells were categorized according to their programmed cell death-1 (PD-1) expression (PD-1high, PD-1int, and PD-1neg cells). Patients were classified based on the presence or absence of discrete PD-1high CD8+ TILs. Production of effector cytokines by CD8+ TILs was measured after T-cell stimulation with or without antibodies against immune checkpoint receptors. Results Progressive T-cell exhaustion with marked expression of exhaustion-related markers and diminished production of effector cytokines was observed in PD-1high CD8+ TILs compared with PD-1int and PD-1neg CD8+ TILs. Patients with distinct PD-1high CD8+ TILs (PD-1high expressers) exhibited characteristics associated with a favorable anti-PD-1 response compared with those without these lymphocytes (non-PD-1high expressers). Combined inhibition of dual immune checkpoint receptors further restored effector cytokine production by CD8+ TILs following T-cell stimulation. PD-1high CD8+ T lymphocyte populations in the peripheral blood and tumors were significantly correlated. Conclusions T-cell exhaustion was differentially regulated among individual patients and was prominent in a subgroup of NSCLC patients who may benefit from PD-1 blockade or combined blockade of other immune checkpoint receptors.

Effect of epidermal growth factor receptor gene mutation on the prognosis of pathological stage II-IIIA (8th edition TNM classification) primary lung cancer after curative surgery. Lung Cancer 2021; 162:128-134. [PMID: 34775216 DOI: 10.1016/j.lungcan.2021.11.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 10/21/2021] [Accepted: 11/03/2021] [Indexed: 12/25/2022]
Abstract
OBJECTIVES This retrospective study aimed to elucidate the effect of epidermal growth factor receptor (EGFR) gene mutations on the prognosis of patients with pathological stage II-IIIA primary lung cancer after curative surgery. MATERIALS AND METHODS We enrolled 539 patients with p-stage II-IIIA (8th edition tumor-node-metastasis [TNM] classification) lung cancer who underwent curative resection at Kanagawa Cancer Center between January 2010 and December 2020 and whose tumors were tested for EGFR mutations. Relapse-free survival (RFS) and overall survival (OS) of patients with EGFR-mutant lung cancer (Mt, n = 126) including EGFR exon 21 L858R point mutation and EGFR exon 19 deletion mutation and EGFR mutation-wild lung cancer (Wt, n = 413) were analyzed using Kaplan-Meier curves and compared using a log-rank test. Cox regression analysis was performed to evaluate the effects of EGFR gene mutations on RFS and OS at each stage. RESULTS There were 56/256 patients with p-stage II EGFR-Mt/Wt and 70/157 patients with p-stage IIIA EGFR-Mt/Wt. The 5-year RFS rate of patients with EGFR-Mt/Wt was 46.6%/52.0% (p = 0.787) for p-stage II and 17.4%/29.7% (p = 0.929) for p-stage IIIA. The 5-year OS rate was 92.0%/65.7% (p = 0.001) for p-stage II and 56.0%/39.3% (p = 0.016) for p-stage IIIA. EGFR-Mt was not an independent prognostic factor for OS of patients with p-stage IIIA lung cancer (hazard ratio [HR], 0.95; 95% confidence interval [CI], 0.51-1.76; p = 0.872); however, EGFR-Mt was an independent favorable prognostic factor for OS of patients with p-stage II lung cancer (HR, 0.59; 95% CI, 0.36-0.96; p = 0.034). CONCLUSION The OS of lung cancer patients with p-stage II or IIIA, classified according to the 8th edition TNM classification, was remarkably favorable. Incorporating EGFR mutations to the anatomical TNM classification may lead to a more accurate prognosis prediction.

Abstract
OBJECTIVES The prognostic role of the epidermal growth factor receptor (EGFR) mutation remains controversial, especially in early-stage lung adenocarcinoma with a solid appearance. We evaluated the oncological outcomes of clinical stage I (c-stage I) radiologically invasive lung adenocarcinoma by EGFR mutation status. METHODS Between 2008 and 2013, the data from 463 surgically resected c-stage I radiologically invasive, i.e. solid-dominant lung adenocarcinomas subjected to EGFR mutant analysis, were evaluated. Oncological outcomes were assessed using multivariable Cox regression analysis. Recurrence-free survival (RFS) was estimated using Kaplan-Meier analysis and the log-rank test. RESULTS A total of 229 (49%) samples harboured the EGFR-mutant adenocarcinoma. Overall, the 5-year RFS did not differ significantly between the EGFR-mutant and EGFR wild-type groups (67.3% vs 64.9%; P = 0.639). However, among the clinical T1c/T2a tumour subset (n = 177), a multivariable Cox hazard model revealed that radiologically pure-solid tumour (P = 0.024), EGFR-mutant (P = 0.027) and pathological stage II/III (P < 0.001) were significant predictors of a poor RFS. Furthermore, in the c-T1c/T2a radiologically pure-solid lung adenocarcinoma subset, the EGFR-mutant group showed marginally lower 5-year RFS compared to that with the EGFR wild-type group (n = 134; 34.9% vs 53.0%; P = 0.062). Among them, multivariable Cox regression analysis revealed that EGFR mutant (P = 0.037) and pathological stage II/III (P = 0.011) were independently and significantly prognostic for worse RFS. CONCLUSIONS Among the c-stage I radiologically invasive lung adenocarcinomas, the EGFR mutation-positive type was correlated with an increased risk of recurrence in the c-T1c/T2a radiologically pure-solid tumour subset. When considering the prognostic value of EGFR mutations in early-stage lung adenocarcinoma, it is necessary to stratify them based on the presence of a ground-glass opacity component.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer death in the US. While an extensive literature exists detailing lung cancer risk factors and mortality among patients with a history of tobacco use, the data are more limited among individuals who have never smoked. The purpose of this investigation is to compare survival rates between the two groups and evaluate potential risk factors among never smokers. METHODS This retrospective study included 3380 smokers and 334 never smokers who were diagnosed with lung cancer at Stony Brook University Hospital between 2003 and 2016. 1-, 3-, 5- and 10-year survival outcomes, stratified by smoking status, were compared and Kaplan-Meier curves for overall survival are provided. Cox Proportional Hazard models were used to evaluate factors influencing survival among never smokers. RESULTS Never smokers with lung cancer were more likely to be female, be diagnosed with adenocarcinoma histology, and had fewer comorbidities than lung cancer patients who smoked. Although 60% of patients were diagnosed at a later stage of disease development, regardless of smoking status, overall short- and long-term survival was significantly higher among never smokers compared to those with a history of tobacco use. In addition to age and stage at diagnosis, a history of diabetes was found to be a significant prognostic factor for decreased survival among never smokers (HR=3.15, 95% CI (1.74, 5.71)). CONCLUSIONS Data from the present investigation suggest that, regardless of smoking status, approximately three of every five lung cancer patients are diagnosed at a later stage, and that both short- and long-term survival outcomes are significantly better among never smokers compared to those with a history of tobacco use. Additional studies are required to validate these findings and better explain the mechanistic drivers for the improved outcomes among never smokers.

Abstract
Background To establish a machine-learning-derived nomogram based on radiomic features and clinical factors to predict post-surgical 2-year progression-free survival (PFS) in patients with lung adenocarcinoma. Methods Patients with >2 years post-surgical prognosis results of lung adenocarcinoma were included in Hospital-1 for model training (n = 100) and internal validation (n = 50), and in Hospital-2 for external testing (n = 50). A total of 1,672 radiomic features were extracted from 3D segmented CT images. The Rad-score was established using random survival forest by accumulating and weighting the top-20 imaging features contributive to PFS. A nomogram for predicting PFS was established, which comprised the Rad-score and clinical factors highly relevant to PFS. Results In the training, internal validation, and external test groups, 69/100 (69%), 37/50 (74%) and 36/50 (72%) patients were progression-free at two years, respectively. According to the Rad-score, the integral of area under the curve (iAUC) for discriminating high and low risk of progression was 0.92 (95%CI: 0.77-1.0), 0.70 (0.41-0.98) and 0.90 (0.65-1.0), respectively. The C-index of Rad-score was 0.781 and 0.860 in the training and external test groups, higher than 0.707 and 0.606 for TNM stage, respectively. The nomogram integrating Rad-score and clinical factors (lung nodule type, cM stage and histological type) achieved a C-index of 0.845 and 0.837 to predict 2-year PFS, respectively, significantly higher than by only radiomic features (all p < 0.01). Conclusion The nomogram comprising CT-derived radiomic features and risk factors showed a high performance in predicting post-surgical 2-year PFS of patients with lung adenocarcinoma, which may help personalize the treatment decisions.

Abstract
Background Invasive mucinous adenocarcinoma (IMA) of the lung is a distinct histological subtype with unique clinical and pathological features. Despite previous genomic studies on lung IMA, the genetic characteristics and the prognosis-related biomarkers in Chinese surgically resected lung IMA remain unclear. Methods We collected 76 surgically resected primary tumors of invasive lung adenocarcinoma, including 51 IMA and 25 non-mucinous adenocarcinomas (non-IMA). IMA was further divided into pure-IMA (mucinous features≥90%) and mixed-IMA subgroups. Comprehensive genomic profiling based on targeted next-generation sequencing (NGS) of 425 genes was explored and genomic characteristics were evaluated for the correlation with postoperative disease-free survival (DFS). Results IMA had a unique genetic profile, with more diverse driver mutations and more tumor drivers/suppressors co-occurrence than that of non-IMA. The frequency of EGFR (72.0% vs. 40.0% vs. 23.1%, p=0.002) and ALK (undetected vs. 20.0% vs. 26.9%, p=0.015) alterations showed a trend of gradual decrease and increase from non-IMA to mixed-IMA to pure-IMA, respectively. The frequency of KRAS mutations in pure-IMA was higher than that in mixed-IMA, albeit statistically insignificant (23.1% vs. 4.0%, p=0.10). TP53 mutation was significantly less in pure-IMA compared to mixed-IMA and non-IMA (23.1% vs. 52.0% vs. 56.0%, p=0.03). Besides, IMA exhibited less arm-level amplifications (p=0.04) and more arm-level deletions (p=0.004) than non-IMA, and the frequency of amplification and deletion also showed a trend of gradual decrease and increase from non-IMA to mixed-IMA to pure-IMA, respectively. Furthermore, prognosis analysis in stage III IMA patients showed that patients harboring alterations in EGFR (mDFS=30.3 vs. 16.0 months, HR=0.19, P=0.027) and PI3K pathway (mDFS=36.0 vs. 16.0 months, HR=0.12, P=0.023) achieved prolonged DFS, while patients with poorly differentiated tumors (mDFS=14.1 vs. 28.0 months, HR=3.75, p=0.037) or with KRAS mutations (mDFS=13.0 vs. 20.0 months, HR=6.95, p=0.027) had shorter DFS. Multivariate analysis showed that KRAS mutations, PI3K pathway alterations, and tumor differentiation status were independent factors that have statistically significant influences on clinical outcomes of IMA patients. Conclusion Our study provided genomic insights into Chinese surgically resected lung IMA. We also identified several genomic features that may serve as potential biomarkers on postoperative recurrence in IMA patients with stage III disease.

Abstract
Defining the optimal neoadjuvant strategy in early-stage and locoregional (N2) oncogenic-driven lung cancer remains a major challenge for the scientific community. Whereas significant advances have been achieved with the use of personalized medicine and targeted therapies in advanced stages, we are still far from translating the same magnitude of benefits into an earlier-stage disease. Perioperative strategies with neoadjuvant and adjuvant tyrosine kinase inhibitors in patients with EGFR and ALK gene alterations have yielded mixed results and further biomarker-driven trials are needed to shed more light on the significance of inhibiting the oncogenic signaling addiction at earlier stages of the disease and the conceivable value of incorporating more potent targeted inhibitors in this setting. Meanwhile, the landscape of early-stage lung cancer management is progressing rapidly, and we anticipate the incorporation of novel immunotherapeutic agents on the basis of this promising preliminary activity as induction strategies. Whether the benefits observed in the overall population can be translated into specific subsets of oncogenic-driven tumors is still unknown, but it clearly reinforces the importance of incorporating—sooner rather than later—a biomarker-testing strategy into the routine work-up of early-stage non-small cell lung cancer (NSCLC). There are still many challenges to overcome such as the need to stablish standardized surrogate endpoints and to define the optimal duration of perioperative treatment, as well as how to expedite patient recruitment using enrichment strategies for biomarker stratified trials. Despite the difficulties, we are living in exciting times and coming up on a new window of opportunities for achieving the ultimate goal of curing early-stage lung cancer and improving long-term outcomes by eliminating the minimal residual disease and reducing the risk for metastatic recurrence.

J Cancer Res Clin Oncol 2020; 147:1169-1178. [PMID: 32980961 DOI: 10.1007/s00432-020-03402-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Accepted: 09/19/2020] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To analyze the relationship between dual-energy spectral CT and epidermal growth factor receptor (EGFR) mutation status in patients with lung adenocarcinoma. METHODS The quantitative parameters of spectral CT were analyzed in 208 patients with lung adenocarcinoma. The quantitative parameters including CT40keV and CT70keV values, effective atomic number (Zeff), iodine concentration (IC), water concentration (WC), and the slope of the spectral curve (λ HU) were calculated. Statistical analysis was used to determine the clinical characteristics and quantitative parameters for the diagnosis of EGFR-mutation status. The ROC curves were used to calculate diagnostic efficiency. RESULTS Sex (p = 0.027) and smoking history (p = 0.019) differed significantly according to the EGFR-mutation status. Spectral CT quantitative parameters (CT40keV and CT70keV values, λ HU, Zeff and IC) differed significantly between the EGFR mutant and the EGFR wild-type groups (p < 0.05) during the arterial phase (AP) and venous phase (VP). However, WC was not statistically different between the two groups (p > 0.05). ROC curve analysis revealed the combination of the significantly different quantitative parameters provided the best diagnostic performance for determining the EGFR-mutation status (AUC: 76.0%) in the AP, while the AUC during the VP was 75.6%. CONCLUSION The quantitative parameters of dual-energy spectral CT have potential value for identifying the EGFR-mutation status.

Abstract
BACKGROUND Mutation of the EGFR gene is known as a predictor for the response to EGFR tyrosine kinase inhibitor. Although EGFR mutation status is proposed to be incorporated in the Ninth Edition of the Lung Cancer Staging system, its prognostic value for surgically resected lung adenocarcinoma remains controversial. METHODS Data on 1512 patients with completely resected lung adenocarcinoma who underwent EGFR mutation analysis between 2008 and 2015 were collected. The prognostic value of EGFR mutations was determined in patients with lung adenocarcinoma stratified by clinicopathologic and radiologic characteristics. Independent prognostic factors were identified by multivariate analysis using the Cox proportional hazards model. Competing risk model was used to estimate the cumulative incidence. RESULTS EGFR mutations were identified in 935 patients (61.8%). In the entire cohort, there was no difference in recurrence-free survival between the EGFR-mutated group and the wild-type group (P = .266). However, Cox multivariate analyses revealed that EGFR mutation was a strong independent prognostic factor for worse recurrence-free survival in patients with radiologic solid tumors (hazard ratio, 1.485; 95% confidence interval, 1.208-1.826; P < .001), histologic acinar pattern-predominant adenocarcinoma/papillary pattern-predominant adenocarcinoma/invasive mucinous adenocarcinoma (hazard ratio, 1.684; 95% confidence interval, 1.330-2.132; P < .001), and pathologic stage II and III (hazard ratio, 1.417; 95% confidence interval, 1.115-1.801; P = .004). Patients with EGFR mutations developed significantly more brain (hazard ratio, 1.827; 95% confidence interval, 1.213-2.766; P = .004) and bone (hazard ratio, 1.724; 95% confidence interval, 1.131-2.631; P = .011) metastases compared with the wild-type cohort. CONCLUSIONS EGFR mutation was a strong poor prognostic factor in patients with radiologic solid, histologic acinar pattern-predominant adenocarcinoma/papillary pattern-predominant adenocarcinoma/invasive mucinous adenocarcinoma, and pathologic stage II and III lung adenocarcinomas. After surgery, distinct metastatic patterns were revealed according to EGFR mutation status. These findings have implications for the upcoming new lung cancer staging system.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) mutation is the most frequently encountered oncogenic driver in lung cancer. Risk factors for EGFR mutation may help prevention, surveillance and diagnosis strategies of EGFR-mutated lung cancer. PATIENTS AND METHODS A nationwide, retrospective, longitudinal, cohort study was performed between January 2002 and December 2015. Patient data were collected from the Korean National Health Insurance Database. The lung cancer group included EGFR tyrosine kinase inhibitor (TKI)-treated patients. Controls were randomly selected from people without a history of lung cancer and determined to be four times the number of patients with EGFR-mutated advanced lung cancer. The risk model of developing EGFR-mutated lung cancer was constructed by multiple logistic regression analysis. RESULTS Among the 2010 new cases of lung cancer treated in 2010-2015, 214 cases were classified as EGFR-mutated advanced lung cancer. The risk of developing EGFR-mutated advanced lung cancer was higher in patients in their 50s (odds ratio [OR]: 3.42; 95% confidence interval [CI]: 1.68-6.93), 60s (OR: 7.04; 95% CI: 3.35-14.77) and 70s (OR: 10.27; 95% CI: 4.73-22.30) and in those aged >80 years (OR: 5.98; 95% CI: 2.25-15.92) than those in their 40s. The risk of developing EGFR-mutated lung cancer was also higher in hospitalised patients with a history of pneumonia (OR: 5.22; 95% CI: 1.88-14.46) and those with gastroesophageal reflux disease (OR: 2.02; 95% CI: 1.32-3.07). CONCLUSIONS Patients with EGFR-mutated advanced lung cancer were associated with ageing, history of being hospitalised for pneumonia and gastroesophageal reflux disease.

Abstract
It is well known that the treatment effect of a molecularly targeted agent (MTA) may vary dramatically, depending on each patient's biomarker profile. Therefore, for a clinical trial evaluating MTA, it is more reasonable to evaluate its treatment effect within different marker subgroups rather than evaluating the average treatment effect for the overall population. The marker-stratified design (MSD) provides a useful tool to evaluate the subgroup treatment effects of MTAs. Under the Bayesian framework, the beta-binomial model is conventionally used under the MSD to estimate the response rate and test the hypothesis. However, this conventional model ignores the fact that the biomarker used in the MSD is, in general, predictive only for the MTA. The response rates for the standard treatment can be approximately consistent across different subgroups stratified by the biomarker. In this paper, we proposed a Bayesian hierarchical model incorporating this biomarker information into consideration. The proposed model uses a hierarchical prior to borrow strength across different subgroups of patients receiving the standard treatment and, therefore, improve the efficiency of the design. Prior informativeness is determined by solving a "customized" equation reflecting the physician's professional opinion. We developed a Bayesian adaptive design based on the proposed hierarchical model to guide the treatment allocation and test the subgroup treatment effect as well as the predictive marker effect. Simulation studies and a real trial application demonstrate that the proposed design yields desirable operating characteristics and outperforms the existing designs.

Abstract
Background To investigate the prognostic impact of epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) rearrangement for the overall survival (OS) of patients with surgically treated lung adenocarcinomas. Methods A total of 689 patients with stage I–III lung adenocarcinomas (male:female = 334:355; median age, 64 years) underwent complete surgical resection between 2007 and 2013. The prognostic impact of EGFR mutation and ALK rearrangement on OS was analyzed using Cox regression analysis. Certain clinicopathological prognostic factors (i.e., age, sex, smoking status, nodule type, solid portion size, pathologic stage, adenocarcinoma subtype, and history of adjuvant chemotherapy) were included for adjustments of the hazard ratio (HR). Results EGFR mutation was observed in 438 patients (64%) and ALK rearrangement was seen in 28 patients (4%). Multivariable‐adjusted Cox regression demonstrated that the prognostic effect of EGFR mutation on OS differed by age (HR, exp.[−5.199 + 0.064*age]). The adjusted HR for EGFR mutation was 0.14 (95% CI: 0.05–0.36; P < 0.001) at 50 years, 0.26 (95% CI: 0.15–0.46; P < 0.001) at 60 years, and 0.50 (95% CI: 0.31–0.81; P = 0.005) at 70 years. However, the effect of ALK rearrangement on OS was without statistical significance (P > 0.05). Conclusions EGFR mutation was independently prognostic of the long‐term outcomes of patients with surgically treated lung adenocarcinomas. A more favorable prognostic effect was seen in younger than in older patients. ALK rearrangement was not associated with OS.

Abstract
OBJECTIVES The goal of this study was to investigate the role of the ground-glass opacity (GGO) ratio in lung adenocarcinoma in predicting surgical outcomes. METHODS Patients who underwent surgical resection for pulmonary adenocarcinoma between January 2004 and December 2013 were reviewed. The clinical data, imaging characteristics of nodules, surgical approaches and outcomes were analysed with a mean follow-up of 87 months. RESULTS Of 789 enrolled patients, 267 cases were categorized as having a GGO ratio ≥0.75; 522 cases were categorized as having a GGO ratio <0.75. The gender, tumour differentiation, epidermal growth factor receptor mutation, smoking habits, lymphovascular space invasion, tumour size, maximum standard uptake value and carcinoembryonic antigen levels were significantly different in the 2 groups. In the group with a GGO ratio ≥0.75, 63.3% of the patients underwent sublobar resection (18.8% with a GGO ratio < 0.75, P <0.001). These patients had fewer relapses (2.2% for GGO ratio ≥0.75, 26.8% for GGO ratio <0.75, P < 0.001) and a better 5-year survival rate (95.5% for GGO ratio ≥0.75, 77.4% for GGO ratio <0.75, P < 0.001). None of the patients with a GGO ratio ≥0.75 had lymph node involvement. The multivariable Cox regression analysis revealed that a GGO ratio <0.75 was an independent factor for postoperative relapse with a hazard ratio of 3.96. CONCLUSIONS A GGO ratio ≥0.75 provided a favourable prognostic prediction in patients with resected lung adenocarcinoma. Sublobar resection and lymph node sampling revealed a fair outcome regardless of tumour size. However, anatomical resection is still the standard approach for patients with tumours with a GGO ratio <0.75, size >2 cm.

Abstract
BACKGROUND This study aimed to explore adjuvant chemotherapy (ACT) candidates based on a recurrence risk-scoring model in completely lobectomized stage I patients with lung adenocarcinoma (LAD). METHODS A retrospective study was performed on 4606 patients (non-ACT group: n = 3514; ACT group: n = 1092) who underwent complete lobectomy for LAD at Shanghai Chest Hospital from 2008 to 2014. The nomogram predicting recurrence-free survival (RFS) was developed in the non-ACT group using Cox proportional hazards regression. The nomogram-based risk score was calculated in the entire cohort. Differences of RFS between the non-ACT and ACT groups were compared as stratified by the risk score. The score cut-off points were determined using the X-tile software. RESULTS Six independent predictors, including age, sex, tumor size, pathological subtype, visceral pleural invasion (VPI), and lymphovascular invasion (LVI) were associated with RFS. The nomogram more accurately predicted RFS than the 8th TNM staging {C-index: 0.784 [95% confidence interval (CI) 0.756-0.812] vs. 0.719 (95% CI 0.689-0.749), p = 0.0017}. A significant RFS difference was observed among the low-, intermediate- and high-risk groups (p < 0.0001), as divided by the optimal cut-points of risk score (203 and 244). ACT did not improve RFS for patients at intermediate-risk, or was even detrimental for low-risk patients; however, improved RFS was observed in ACT receivers at high-risk (p = 0.0416). ACT candidates with a risk score ≥ 245 constituted 2.6% of stage I patients. CONCLUSIONS The nomogram provided an individual prediction of RFS for stage I LAD following lobectomy. High-risk patients (score ≥ 245) may benefit from postoperative ACT.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) mutation represents a good response to EGFR-tyrosine kinase inhibitor and an advantageous prognostic factor in advanced-stage non-small cell lung cancer (NSCLC). However, the predictive value of EGFR mutation for prognosis in NSCLC patients after complete surgery, which more reflective of natural process, remains controversial. We sought to examine the predictive value of EGFR mutation in NSCLC. Several studies with small sample sizes have been reported but small studies bring bias especially in a postoperative setting. Therefore, we sought to pool all current evidence to show the true effects. METHODS Electronic databases were used to search the relevant articles. Disease-free survival (DFS), which will be less effected by subsequent treatments after recurrence, was the primary endpoint. The DFS between EGFR mutated and wild-type patients were compared focus on stage I patients who are rarely received adjuvant therapy. Besides, the DFS of patients with 19 exon deletion (19del) and 21 exon L858R mutation (L858R) were compared. A random effects model was used. RESULTS A total of 19 relevant studies which involved 4,872 cases were enrolled and 2,086 patients were EGFR-mutated. The majority of studies used PCR-based methods to detect EGFR mutations. Through meta-analysis, we observed the DFS of EGFR-mutated patients were similar to wild type patients in overall population (HR 0.93, 95% CI: 0.74 to 1.17). Similar results were observed in stage I subgroup (HR 0.82, 95% CI: 0.50 to 1.33). DFS of 19 del patients were potentially inferior to L858R patients but the difference was not significant (HR 1.38, 95% CI: 0.76 to 2.52). CONCLUSIONS There was no significant difference in postoperative DFS between EGFR-mutant patients and wild-type with resected NSCLC. In addition, there is still insufficient evidence to support different postoperative treatment strategies (especially for stage I) for both mutated and wild-type patients. However, 19 del may be a negative factor, which may require more strict management. Thus, we strongly encourage reporting specific prognostic impacts of different mutation types.

Lung cancer survival among never smokers. Cancer Lett 2019; 451:142-149. [PMID: 30851418 DOI: 10.1016/j.canlet.2019.02.047] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2018] [Revised: 02/13/2019] [Accepted: 02/28/2019] [Indexed: 11/22/2022]
Abstract
Lung cancer incidence among never smokers has increased in recent decades with 10-30% of all lung cancers occurring in never smokers, where exposure to residential radon is the leading cause of this disease. Lung cancer survival is low, ranging from 12% to 16% at 5 years of diagnosis. There is scant evidence to date on survival from this disease in never smokers. We aim to evaluate lung cancer survival in never smokers and ascertain whether there might be differences regarding smokers, through a systematic review applying predefined inclusion and exclusion criteria. 17 Studies were included. Never-smoker lung cancer patients seem to experience longer survival times than do smokers or ex-smokers. Lung cancer in never smokers displays distinctive clinical characteristics, is more frequent among women, is diagnosed at more advanced stages, and the predominant histologic type is adenocarcinoma. Further studies are necessary to ascertain lung cancer survival among never smokers.

Abstract
Objectives A retrospective study was performed to investigate the association between EGFR mutations and visceral pleural invasion (VPI), and evaluate the prognostic value of EGFR in resected non-small-cell lung cancer (NSCLC) patients with VPI. Materials and methods Clinicopathological characteristics and follow-up information were collected from 508 consecutive patients with surgically resected stage I–III NSCLC, and EGFR mutations were detected based on real-time PCR technology. Significant results (P<0.05) from univariate logistic regression analysis were involved as covariates to adjust confounding factors in the analysis of independent factors. Results VPI and EGFR mutations were detected in 229 (45.1%) and 243 (47.8%) cases in NSCLC, respectively. There was a significant association between EGFR mutations and VPI development. Both 19-del (adjusted OR =2.13, 95%CI =1.13–3.99, P=0.019) and L858R (adjusted OR =2.89, 95%CI =1.59–5.29, P=0.001) could significantly increase the risk of VPI development compared with EGFR wild-type. Higher frequency of L858R (adjusted OR =2.63, 95%CI =1.42–4.88, P=0.002) was detected in VPI patients compared with non-VPI patients. 19-del (adjusted HR =0.31, 95%CI =0.12–0.80, P=0.015) was an independent prognostic factor for a better disease-free survival (DFS) in non-VPI patients. No significant association was shown between EGFR mutations and DFS in VPI patients. Conclusion EGFR mutations were significantly associated with VPI development in NSCLC, but no significant association was observed between EGFR mutations and DFS in the patients with VPI. 19-del was a favorable prognostic factor for DFS in non-VPI patients.

Abstract
OBJECTIVES The prognostic effects of epidermal growth factor receptor (EGFR) gene mutation on lung adenocarcinoma recurrence have not been well established. The relationship between EGFR gene mutation and recurrence dynamics of lung adenocarcinoma was investigated. METHODS A total of 527 patients with complete resection for adenocarcinoma were reviewed retrospectively. EGFR gene mutation was analysed by polymerase chain reaction followed by bidirectional direct sequencing in recurred patients. Patients were divided into the EGFR gene mutation group (M) or the wild-type EGFR gene group (W). Recurrence types and disease-free intervals (DFIs) of the 2 groups were compared. DFIs were calculated by the Kaplan-Meier method and compared using the log-rank test and Cox proportional hazard model. RESULTS EGFR gene sequencing was performed in 115 recurrent adenocarcinoma patients. Sixty-six patients had EGFR mutations and 49 patients had wild-type EGFR. The median DFI of the 2 groups were significantly different (M: 20.3 months, W: 15.1 months, P = 0.012). EGFR gene mutation was the only prognostic factor for DFI [hazard ratio (HR) = 0.639, 95% confidence interval (CI) = 0.428-0.954, P = 0.029]. The proportion of loco-regional recurrences and distant metastases of both groups were similar (P = 0.50). In subgroup analysis, EGFR gene mutation (HR = 0.534, 95% CI = 0.339-0.839, P = 0.007) was a significant prognostic factor for DFI of distant metastases. CONCLUSIONS Lung adenocarcinoma with EGFR gene mutations had longer DFI than those with wild-type EGFR gene, especially with regard to distant metastasis. EGFR gene mutation was a prognostic factor for lung adenocarcinoma.

Thorac Cancer 2018; 9:1594-1602.

Abstract
BACKGROUND This study was conducted to evaluate the prognostic and recurrent impact of EGFR mutation status in resected pN0M0 lung adenocarcinoma with consideration of the histological subtype. METHODS Following retrospective analysis of whole 474 consecutive pathological N0M0 lung adenocarcinoma patients, the prognostic significance of EGFR mutation status was evaluated in limited 394 subjects. Overall survival and recurrence-free interval (RFI) were estimated using the Kaplan-Meier method and compared using a log-rank test. Univariate and multivariate analyses were performed using Cox proportional hazard models. RESULTS The five-year RFI was 85.7% and 93.3% for EGFR positive (n = 176) and negative (n = 218) cases, respectively (hazard ratio [HR] 1.992, 95% confidence interval [CI] 1.005-3.982; P = 0.048). Following the exclusion of specific subtypes free from recurrence or EGFR mutation (adenocarcinoma in situ, minimally invasive adenocarcinoma, and invasive mucinous adenocarcinoma), the five-year RFI was obviously poorer in EGFR positive compared to negative cases (80.7% and 92.1%, respectively; HR 2.163, 95% CI 1.055-4.341; P = 0.035). Multivariate analysis excluding the specific subtypes confirmed that male sex, age, current or Ex-smoking status, pleural invasion, and EGFR-positive status were independently associated with shorter RFI. No significant differences in five-year overall survival were found between the EGFR mutation positive and negative groups (88.7% and 93.7%, respectively; HR 1.630, 95% CI 0.787-3.432; P = 0.2). CONCLUSION EGFR mutations are associated with recurrence in pN0M0 lung adenocarcinoma. EGFR mutation status and histological subtype should be considered when evaluating the risk of recurrence in resected lung adenocarcinoma patients.

Abstract
Background The prognostic value of EGFR and KRAS mutations in resected non-small cell lung cancer (NSCLC) has been reported. However, conflicting results were reported in these studies. The effect of mutations in these two genes in resected NSCLC remains controversial. Methods We searched Internet databases for studies reporting disease-free survival (DFS) and overall survival (OS) in resected NSCLC patients with EGFR or KRAS mutations. A meta-analysis calculating the pooled hazard ratio (HR) for DFS and OS was used to measure the association of EGFR or KRAS mutations with the prognosis of patients after surgery. Results A total of 9,635 patients from 32 studies were included in this analysis. The combined HR for EGFR mutations on DFS was 0.77 (95% CI 0.66–0.90, p=0.001) and on OS was 0.72 (95% CI 0.66–0.80, p<0.00001). In addition, the combined HR for KRAS mutations on DFS was 1.5 (95% CI 1.15–1.96, p=0.002) and on OS was 1.49 (95% CI 1.28–1.73, p<0.00001). Sensitivity analysis, subgroup analysis, and bias analysis proved the stability of the results. Conclusion The analysis showed that EGFR mutations were significantly associated with DFS and OS. These findings indicated that surgically treated NSCLC patients with EGFR mutations were inclined to exhibit a prolonged DFS and OS. In addition, the results indicated that KRAS mutations predicted worse DFS and OS in patients with resected NSCLC.

Abstract
BACKGROUND Since 2013, clinical practice guidelines recommend EGFR mutation testing of non-squamous NSCLC to select advanced-stage patients for first-line treatment using EGFR-TKIs. OBJECTIVE We aimed to determine population-based trends in the real-world uptake and impact in routine practice of these recently updated testing guidelines. PATIENTS AND METHODS A population-based observational study was conducted of notifications to the New Zealand Cancer Registry of patients eligible for EGFR testing diagnosed in northern New Zealand between January 2010 and April 2014. The main study variable was EGFR mutation testing. Main outcome measures (overall survival and dispensing of EGFR-TKIs) were extracted from prospectively archived electronic databases until October 2015. RESULTS The population-based cohort of 1857 patients had an average age of 70 years. Most had adenocarcinoma and metastatic disease at diagnosis. EGFR testing was undertaken in 500 patients (27%) with mutations detected in 109 patients (22%). EGFR testing increased during the period of study from <5% to 67% of patients (P < 0.0001). Full uptake of testing by all eligible patients was limited by a lack of availability of specimens for testing and variable testing referral practices. The proportion of patients treated with EGFR-TKIs decreased during the same time period, both among untested patients (from 12.2% to 2.8% (P < 0.0001)) and in the population as a whole (from 13.7% to 10.6% (P < 0.05)). EGFR testing was associated with prolonged overall survival (Adjusted HR = 0.76 (95% CI, 0.65-0.89) Log-rank P < 0.0001) due at least in part to the much longer overall survival achieved by mutation-positive patients, of whom 79% received EGFR-TKIs. Compared to untested EGFR-TKI-treated patients, mutation-positive EGFR-TKI-treated patients received EGFR-TKIs for longer, and survived longer both from the start of EGFR-TKI treatment and date of their diagnosis. CONCLUSIONS In this real world setting, high uptake of EGFR testing was achieved and associated with major changes in EGFR-TKI prescribing and improved health outcomes. Modifiable factors determined testing uptake. Study registration ACTRN12615000998549.

Abstract
OBJECTIVES We investigated the relationship between computed tomography (CT) characteristics and epidermal growth factor receptor (EGFR) mutations in a large Asian cohort who received surgical resection of invasive lung adenocarcinoma. MATERIALS AND METHODS We retrospectively included 864 patients (524 with EGFR mutation and 340 with EGFR wild-type) who received surgical resections for invasive lung adenocarcinomas. After applying propensity score matching, 312 patients with mutated EGFR were matched with 312 patients with wild-type EGFR. CT characteristics, predominant histologic subtype, and CT measurement parameters (volume and estimated diameter of the total tumor and inner solid portion and ground-glass opacity [GGO] proportion) were compared within matched pairs. RESULTS Tumors in the EGFR mutation group showed higher proportions of pure ground-glass nodules (4.1% vs 1.3%), GGO-predominant (23.7% vs 14.7%), and solid-predominant part-solid nodules (37.2% vs 31.7%) CT characteristics, whereas EGFR wild-type tumors predominantly presented as pure solid nodules (34.6% vs 52.2%, P < 0.0001). EGFR mutation tumors more frequently had a lepidic-predominant subtype than did EGFR wild-type tumors (20.2% and 11.9%; P < 0.0001), and showed a smaller whole tumor size and solid portion (P < 0.0001) with a higher GGO proportion (P < 0.0001). Tumors with exon 21 missense mutations showed the highest GGO proportion and the smallest inner solid portion size, followed by tumors harboring an exon 19 deletion, compared with EGFR wild-type tumors (posthoc P < 0.01). CONCLUSION Adenocarcinomas with EGFR mutations had a higher GGO proportion than those with wild-type EGFR after matching of clinical variables. Lesions with an exon 21 mutation had a higher GGO proportion than lesions with other mutations.

Abstract
INTRODUCTION Somatic mutations are becoming increasingly important biomarkers for treatment selection and outcome in patients with non-small-cell lung cancer (NSCLC). The role of multiple somatic mutations in early-stage NSCLC is unclear. METHODS Tissue from 214 patients with resected NSCLC at the Princess Margaret Cancer Centre was analyzed by next-generation sequencing by Mi-SEQ or Sequenom multiplex platforms. Associations between mutation status, baseline patient characteristics and outcomes (disease-free survival (DFS) after surgical resection and overall survival (OS)) were investigated. RESULTS Somatic mutations were identified in 184 patients with resected stage I-III NSCLC: None (n = 30), single (n = 101) and multiple (≥2, n = 83). Multiple mutations were significantly associated with younger age (p = 0.0006), female sex (p = 0.012), smoking status (p = 0.002) and adenocarcinoma histology (p = 0.0001).TP53, KRAS and EGFR were the most common mutations. TP53 mutation was the most frequent co-mutation occurring in 72% of patients with multiple mutations. In resected stage I-III patients, multiple mutations were significantly associated with worse DFS (HR = 2.56, p = 0.003) but not OS on univariate analysis. Patients with KRAS and EGFR mutations were also associated with shorter DFS (HR = 2.52, p = 0.016 and HR = 4.37, p = 0.001 respectively) but no OS difference. TP53 mutation was associated with both shorter DFS (HR = 2.21, p = 0.02) and OS (HR = 3.08, p = 0.02). In subgroup univariate analysis, poorer DFS was associated with multiple mutations (p = 0.0015), EGFR (HR = 3.14, p = 0.006), and TP53 (HR = 2.46, p = 0.018) in patients with stage I disease. CONCLUSION The presence of known somatic mutations is associated with worse DFS in resected NSCLC. The differences are both statistically significant and clinically relevant. The presence of EGFR, KRAS and TP53 mutations was also associated with adverse outcomes. Larger datasets are required to validate whether mutational status is an independent prognostic factor in early stage NSCLC.

Abstract
Background Despite complete resection, patients with resectable non-small cell lung cancer (NSCLC) sometimes experience recurrence in various sites, generally with an unfavorable prognosis. Receptor tyrosine kinase inhibitors (TKIs) have produced a dramatic response in patients with advanced NSCLC harboring sensitive mutations. Methods We retrospectively investigated 281 patients with recurrence who underwent complete resection of their NSCLC between January 2005 and December 2013 with tumors in which the status of epidermal growth factor receptor (EGFR) mutation, KRAS mutation, and anaplastic lymphoma kinase (ALK) rearrangement was confirmed. Clinicopathological factors, including mode of recurrence, oncogenic status, and postrecurrence survival (PRS), were reviewed. We aimed to investigate the prognostic factors of PRS by univariate and multivariate analyses. Results Among the 281 patients, 135 patients (48.0%) with EGFR mutation, 33 (11.7%) with KRAS mutation, 13 (4.7%) with ALK rearrangement, and 100 (35.6%) with triple negative (TN) mutation were identified. Median survival time after recurrence was 26.1 months. In multivariate analysis, the presence of EGFR mutation, pStage I, the presence of both local and systemic therapies for recurrence, and longer time to recurrence (TTR) were significant favorable factors for PRS. With regard to the initial site of recurrence, the presence of pleural and/or bone recurrence reduced PRS significantly. The presence of pulmonary recurrence increased PRS, especially in patients with EGFR- or ALK-mutated tumors. Conclusions This study documented the current outcomes of PRS. EGFR mutated status, pStage I, longer TTR and presence of multimodal therapy for recurrence were favorable factors for PRS.

Abstract
Introduction The prognostic value of epidermal growth factor receptor (EGFR) mutations and the correlation between EGFR mutations and the new International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society (IASLC/ATS/ERS) histological classification remain controversial. The current study aimed to investigate the pure prognostic role of EGFR mutations in treatment-naïve patients with resected stage I lung adenocarcinoma. Methods We retrospectively reviewed 373 patients with stage I pulmonary non-small-cell lung cancer who underwent complete surgical resection between January 2010 and May 2014. The tumors were classified according to IASLC/ATS/ERS criteria. EGFR mutation status was determined by established methods. Results A total of 120 patients were included for analysis; 87 had tumors with EGFR mutations and 33 had wild-type tumors. More low- and intermediate-grade tumors had EGFR mutations, and nearly half of the high-grade tumors were wild-type (75.7% versus 46.2%, p = 0.041). Patients with low-grade tumors had significantly greater median disease-free survival (DFS) (76.8 versus 13 months, p < 0.0001) and better overall survival (OS) (median OS not reached, p = 0.0003) than those with intermediate- and high-grade tumors. Tumor recurrence was 41.4% and 30.3% in mutant and wild-type patients. The 5-years survival rate was 54% and 71.2%. Multivariate analysis revealed that the new histological classification and the pathologic stage were independent predictors of both DFS and OS. EGFR mutation status had no prognostic implications. Conclusion Low grade tumors according to IASLC/ATS/ERS histological classification and the pathologic stage IA tumors of resected stage I lung adenocarcinomas independently predict better DFS and OS. EGFR mutations were frequently seen in histologically low- and intermediate-grade tumors but not a prognostic factor.

Abstract
Objective We previously reported that the staging system and epidermal growth factor receptor (EGFR) mutation status are key factors for treatment strategy and predicting survival. However, the significance of these factors as predictors of overall survival (OS) and postoperative recurrence survival (PRS) has not been sufficiently elucidated. The objective here was to investigate EGFR mutation status and p-stage, which affect PRS and OS in patients with completely resected lung adenocarcinoma, using a different database. Patients and methods We retrospectively reviewed 56 consecutive lung adenocarcinoma patients with disease recurrence in St. Marianna University Hospital between January 2010 and December 2014. Results EGFR mutants (M) were detected in 16/56 patients (29%). The patients with EGFR M had a better OS than those with EGFR wild-type (WT) status (5-year survival: 50.3% vs 43.1, P=0.133). There was no significant difference in the 3-year recurrence-free survival rate between patients with M and WT (6.3% vs 7.7%, P=0.656), and the patients with EGFR M had a significantly better 3-year PRS than those with WT (77.4% vs 51.7%, P=0.033). The 3-year PRS rate for patients with M/pathologic stage (p-stage) I–II (87.5%) was better than that for patients with M/p-stage III (60.0%), WT/p-stage I–II (52.7%), and WT/p-stage III (43.8%). There was a significant difference between patients with M/p-stage I and WT/p-stage I–II or WT/p-stage III (P=0.021 and 0.030, respectively). During the study period, of the 16 patients with mutants, 12 patients (75%) received EGFR-tyrosine kinase inhibitor (TKI) therapy and among the 40 patients with WT, no patient received EGFR-TKI therapy. Multivariate survival analysis showed that patients with EGFR-TKI therapy had a statistically significant association with favorable PRS (hazard ratio 0.271; 95% confidence interval 0.074–1.000; P=0.050). Conclusion EGFR status and p-stage were found to be essential prognostic factors for estimating PRS using this database. The recurrent patients with EGFR M and EGFR-TKI therapy had a statistically significant association with favorable PRS.

Abstract
OBJECTIVES Over the past decade, the biological and clinical characteristics of lung cancer with epidermal growth factor receptor (EGFR) mutation have been well studied. However, most studies have focused on advanced inoperable cancer, and not on resected early-stage lung adenocarcinoma. We aimed to elucidate the differences in the clinicopathological characteristics and postoperative prognosis according to the EGFR mutation status in early-stage lung adenocarcinoma. MATERIALS AND METHODS We retrospectively collected clinical and pathological data from 369 patients with pathological stage I or II lung adenocarcinoma who underwent complete resection. Clinicopathological characteristics and postoperative prognosis were compared depending on the EGFR mutation status, using the Chi-squared test and the log-rank test, respectively. RESULTS AND CONCLUSION Of the 369 patients, 160 (43.3%) had EGFR mutation, of which 64 (40.0%) were exon 19 deletion (Del-19) and 90 (56.3%) were exon 21 point mutation L858R. Although there was no difference in overall survival (OS) between patients with and without EGFR mutation (p=0.086), tumors with EGFR mutation were associated with a lower consolidation to tumor ratio (CTR) (p <0.001) and a higher incidence of a lepidic growth pattern by pathological evaluation (p <0.001) compared to those without EGFR mutation. Among tumors with EGFR mutation, there was no difference in OS (p=0.140) between Del-19 and L858R. Tumors with L858R were associated with a lower CTR (p=0.046), and tended to have a higher incidence of a lepidic growth pattern by pathological evaluation (p=0.073) compared to those with Del-19. In conclusion, although EGFR mutation status was not a prognostic indicator after surgery in early-stage lung adenocarcinoma, L858R and Del-19 had different radiological and pathological features.

Abstract
RATIONALE The pathogenesis and progression of lung cancer is a complicated process in which many genes take part. But molecular gene testing is typically only performed in advanced-stage non-squamous non-small-cell lung cancer (NSCLC). The value of tyrosine kinase inhibitors (TKI) administration is not widely recognized with respect to early-stage NSCLC. PATIENT CONCERNS Here, we present a case of a man, heavy smoker who initially presented with stage IA lung adenocarcinoma (LADC). Three years after a lung lobectomy, he was diagnosed with advanced lung squamous cell carcinoma (SCC), according to laboratory, imaging, and pathological examinations. DIAGNOSES The case initially had an early-stage LADC with an L858R epidermal growth factor receptor (EGFR) mutation. A subsequent advanced SCC bearing EGFR L858R/T790M mutations occurred 3 years after surgery. INTERVENTIONS The comprehensive therapy we utilized, including surgical resection for the early-stage lesion and GP chemotherapy and local radiotherapy as the first line therapy along with gefitinib maintenance treatment for the advanced metachronous second primary tumors (MST). OUTCOMES The synthetical therapy, have resulted in our patient with remaining alive and progression free for 4.5 years. LESSONS This case suggests that changes in molecular pathology should be monitored closely throughout cancer progression to guide personalized therapy and improve prognosis. We further review administration of TKI to early-stage NSCLC and to the metachronous second primary tumors (MST) in survivors.

Abstract
BACKGROUND The proportion of never-smokers with non-small cell lung cancer (NSCLC) is increasing, but that in Korea has not been well addressed in a large population. We aimed to evaluate the proportion and clinical features of never-smokers with NSCLC in a large single institution. METHODS We analyzed clinical data of 1860 consecutive patients who were newly diagnosed with NSCLC between June 2011 and December 2014. RESULTS Of the 1860 NSCLC patients, 707 (38.0%) were never-smokers. The proportions of women (83.7% vs. 5.6%) and adenocarcinoma (89.8% vs. 44.9%) were higher among never-smokers than among ever-smokers. Significantly more never-smokers were diagnosed at a younger median age (65 vs. 68 years, P < 0.001) and earlier stage (stage I-II, 44.5% vs. 38.9%, P = 0.015) compared with ever-smokers. Epidermal growth factor receptor mutations (57.8% vs. 24.4%, P < 0.001) and anaplastic lymphoma kinase rearrangements (7.8% vs. 2.8%, P < 0.001) were more common in never-smokers, whereas Kirsten rat sarcoma viral oncogene homolog mutations (5.8% vs. 9.6%, P = 0.021) were less frequently encountered in never-smokers than in ever-smokers. Never-smokers showed longer survival after adjusting for the favorable effects of younger age, female sex, adenocarcinoma histology, better performance status, early stage disease, being asymptomatic at diagnosis, received antitumor treatment, and the presence of driver mutations (hazard ratio, 0.624; 95% confidence interval, 0.460-0.848; P = 0.003). CONCLUSIONS More than one-third of the Korean patients with NSCLC were never-smokers. NSCLC in never-smokers had different clinical characteristics and major driver mutations and resulted in longer overall survival compared with NSCLC in ever-smokers.

Superior Treatment Response and In-field Tumor Control in Epidermal Growth Factor Receptor-mutant Genotype of Stage III Nonsquamous Non-Small cell Lung Cancer Undergoing Definitive Concurrent Chemoradiotherapy. Clin Lung Cancer 2016; 18:e169-e178. [PMID: 28131636 DOI: 10.1016/j.cllc.2016.12.013] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2016] [Revised: 12/20/2016] [Accepted: 12/20/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Although previous in vitro data have suggested a more radio-sensitive nature of epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) cell lines, the clinical behavior according to the EGFR mutational status has not been well-established. In this study, we performed a comparative outcome analysis of EGFR-mutant and wild-type locally advanced NSCLC with chemoradiotherapy (CRT). PATIENTS AND METHODS A total of 102 patients with stage III nonsquamous NSCLC undergoing primary CRT were identified. Clinicopathologic characteristics, including the degree of glucose uptake, were evaluated. Failure patterns considering the radiation field and survival outcomes were compared according to the EGFR mutational status. RESULTS Pre- and post-CRT maximum standardized uptake values were significantly lower in EGFR-mutant tumors (P = .010 and .018, respectively). The overall response rate was higher in the EGFR-mutant group compared with the wild-type (89% vs. 64%, respectively; P = .023). The 3-year overall survival rate was better with the genetic alteration (68.0% vs. 47.4%, P = .046), but the statistical significance did not remain in multivariate analysis (hazard ratio, 0.68; 95% confidence interval, 0.30-1.55). Considering the tumor progression inside or outside the radiation field, the EGFR-mutant group showed longer in-field time to progression (P = .002), even after adjusting for other related baseline variables (hazard ratio, 0.27; 95% confidence interval, 0.11-0.71). CONCLUSION The differential metabolic activity, failure patterns, and prognosis suggest the distinct nature of the EGFR-mutant tumors. EGFR mutational status needs to be considered for more precise curative-intent treatment strategies of locally advanced nonsquamous NSCLC.

Abstract
Background The prognostic role of epidermal growth factor receptor (EGFR) mutations in patients with lung adenocarcinomas remains controversial and the association between EGFR mutations and stage at the time of the initial diagnosis is debatable. In this study, we evaluated the association of EGFR mutations with stage at diagnosis in lung adenocarcinomas. Materials and Methods We retrospectively analyzed 1004 consecutive patients who were diagnosed with lung adenocarcinomas and tested for EGFR mutations between June 2011 and December 2014. Results EGFR mutations were detected in 49.2% of 1004 patients with lung adenocarcinomas. In multivariable analysis, EGFR mutations were significantly associated with early stage disease (stage I to II) at diagnosis (odds ratio [OR], 0.65; 95% confidence interval [CI], 0.49–0.87; P = 0.003). When adjusted for age, sex, smoking status, and screening, the adjusted proportion of EGFR mutations significantly decreased according to stage. The adjusted proportions of EGFR mutations were 57.6% (95% CI, 51.7%–63.3%) for stage I, 47.9% (95% CI, 36.9%–59.0%) for stage II, 47.5% (95% CI, 39.6%–55.5%) for stage III, and 43.4% (95% CI, 38.3%–48.6%) for stage IV (P = 0.0082). Conclusions The presence of EGFR mutations is significantly associated with early stage disease at initial diagnosis in lung adenocarcinomas after adjusting for age, sex, smoking status, and screening. This finding implies that EGFR mutations may play a role as a positive prognostic marker.

[PMID: 27402797 DOI: 10.1093/jjco/hyw094] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2016] [Accepted: 06/14/2016] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE Surgical resection is employed in patients with resectable non-small cell lung cancer. Despite complete resection, recurrence is sometimes observed. Oncogenic mutations promote initiation and progression of lung cancer, and mutation status predicts treatment outcome of advanced non-small cell lung cancer; however, their impact on the recurrence patterns remains poorly understood. METHODS We retrospectively studied 401 patients showing recurrence after complete resection of non-small cell lung cancer. Clinicopathological factors were reviewed for time to recurrence, and recurrence patterns were compared according to oncogenic status and examined according to EGFR mutational subtype. RESULTS Among 401 patients, 185 with EGFR mutation, 46 with KRAS mutation, 15 with ALK rearrangement and 155 with triple-negative mutation were identified. Multivariate analysis following univariate analyses showed that younger age, well-moderately-differentiated histology, earlier pathologic stage and presence of EGFR or ALK mutation were favorable prognostic factors for time to recurrence. Locoregional recurrence was observed in 53.3% of ALK-positive patients, being significantly common in these patients than in EGFR- and KRAS-positive patients. EGFR-positive patients mostly experienced pleural recurrence, the incidence of which was significantly higher in triple-negative mutation patients. Adrenal recurrence was observed in 7.2% of triple-negative mutation patients, but it was rarely identified in EGFR-positive patients. Among EGFR-positive patients, the incidence of brain metastases was significantly higher in L858R cohort than in Del Ex19 cohort. CONCLUSIONS In resected non-small cell lung cancer, younger age, well-moderately-differentiated histology, earlier pathologic stage and presence of EGFR or ALK mutation were favorable factors for TTR, and distinct recurrence patterns were revealed according to oncogenic mutation status and mutational EGFR subtype. Our results may provide suggestions for developing a strategy for follow-up and adjuvant therapies after resection.
