Abstract
INTRODUCTION Despite the heterogeneity among patients with stage IB-IIA non-small cell lung cancer (NSCLC), clinically applicable models to identify patients most suitable for receiving adjuvant chemotherapy (ACT) are limited. We aimed to develop a model for risk stratification and the individualized application of ACT. METHODS Between January 2008 and March 2018, patients with T2N0M0 NSCLC at Sun Yat-sen University Cancer Center were retrospectively enrolled. Survival curves were estimated by Kaplan-Meier method and compared with log-rank test. Cox regression models were used to identify prognostic factors for disease-free survival (DFS) and overall survival (OS). Propensity score matching (PSM) was implemented. Subgroup analysis was performed based on clinical risk score (CRS) value and epidermal growth factor receptor (EGFR) mutation status. RESULTS Of 1063 patients with T2N0 NSCLC enrolled, 272 patients received ACT. Before PSM, patients with high CRS (>1) had a significantly worse OS and DFS outcomes. In the PSM, the baseline characteristics of the 270 pairs of patients were well matched. ACT was associated with improved OS outcomes for patients with a high CRS, while ACT was associated with improved OS and DFS outcomes in patients with wild-type EGFR. The interaction analysis showed an apparent interaction effect between ACT and EGFR-activating mutations as well as chemotherapy regimens and histology. CONCLUSIONS The CRS can predict the prognosis of patients with stage IB-IIA NSCLC. ACT could improve the outcome of patients with a high CRS. Patients with non-squamous cell histology receiving pemetrexed plus platinum might benefit more, but not those with EGFR-activating mutations.

Efficacy of Platinum-Based Adjuvant Chemotherapy on Prognosis of Pathological Stage II/III Lung Adenocarcinoma based on EGFR Mutation Status: A Propensity Score Matching Analysis. Mol Diagn Ther 2020; 23:657-665.

Abstract
OBJECTIVE This study aimed to retrospectively evaluate the efficacy of platinum-based adjuvant chemotherapy (PBAC) for patients with pathological II/III pulmonary adenocarcinoma after curative resection based on epidermal growth factor receptor (EGFR) mutation status using propensity score matching (PSM) analysis. METHODS Among the 304 patients who underwent curative resection of the lung for pathological II/III pulmonary adenocarcinoma from 2002 to 2016 at the Kanagawa Cancer Center, 176 and 128 patients were wild-type EGFR (Wt) and mutant EGFR (Mt), respectively. Seventy-one Wt patients (40.3%) and 60 Mt patients (46.9%) received PBAC. The prognoses of Wt and Mt patients who did and did not receive PBAC were compared using PSM analysis to reduce bias. RESULTS The overall survival (OS) of both Wt and Mt patients who received PBAC was significantly better than that of patients who did not receive PBAC before PSM. By multivariate analysis, PBAC was an independent prognostic factor for OS among Wt patients, as were age, carcinoembryonic antigen (CEA) level, pleural invasion, and lymph node metastasis. Although age and CEA level were independent factors for OS among Mt patients, PBAC was not a prognostic factor. After PSM, Wt patients who received PBAC had better OS than those who did not, although Mt patients who did and did not receive PBAC had no difference in OS. CONCLUSIONS PBAC was associated with favorable prognosis after curative resection among Wt patients, but not among Mt patients. PBAC might not be necessary for Mt patients with pathological stage II/III pulmonary adenocarcinoma.

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.

Abstract
Purpose In 699 patients with locally advanced non–small-cell lung cancer (NSCLC) treated with radiation therapy as part of combined modality therapy, we compared outcomes among genotyped and ungenotyped patients and by tumor genotype status ( EGFR, KRAS, and ALK). Patients and Methods Genotyping was performed in 250 patients: EGFR+ (19%), KRAS+ (32%), ALK+ (9%), and wild type (WT−/−/−; 40%). Outcomes were analyzed using the Kaplan-Meier method and Cox regression. Results With a median follow-up of 48.2 months among genotyped patients, median overall survival (OS) was significantly longer for EGFR+ and ALK+ compared with KRAS+ and WT−/−/− (55.8 months v not reached v 28.0 v 33.2 months; P = .02). There was no difference in progression-free survival (median, 15.3 v 13.7 v 13.0 v 14.5 months; P = .47) or in freedom from distant metastases by genotype (3-year estimates: 42% v 49% v 27% v 25%; P = .25). There was higher freedom from locoregional recurrence (LRR) for EGFR+ tumors and lower freedom from LRR in ALK+ tumors, compared with KRAS+ and WT−/−/− tumors (3-year: 77% v 38% v 49% v 46%). In multivariable analysis, ALK+ remained associated with increased OS (HR, 0.32; 95% CI, 0.12 to 0.87; P = .03), and EGFR+ was associated with decreased LRR (HR, 0.47; 95% CI, 0.24 to 0.92; P = .03). Analysis of post-recurrence survival demonstrated that EGFR+/ ALK+ patients treated with appropriate tyrosine kinase inhibitors had higher OS compared with other groups. Conclusion In this series of locally advanced NSCLC treated with combined modality therapy, EGFR+ and ALK+ were associated with higher OS, whereas LRR was lower in EGFR+ patients, and the risk of distant metastases was high in all subgroups. The outcomes and patterns of failure in genotypic subgroups of NSCLC from this study can inform the design of future trials integrating targeted therapies.

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
PURPOSE We retrospectively assessed the role of C-MET expression and epidermal growth factor receptor (EGFR) mutation on survival following platinum-based adjuvant chemotherapy. The impact of C-MET on survival was also investigated in relation to EGFR mutation status. METHODS We enrolled 311 patients with resected lung adenocarcinoma (high-risk stage 1B-3A), and performed immunohistochemistry (IHC) using C-MET- and mutant EGFR (EGFRmut)-specific antibodies in tissue microarrays. RESULTS Adjuvant chemotherapy was administered to 151 patients, 96 of whom relapsed and 85 died by the end of the study. On IHC, C-MET and EGFRmut were positive in 141 (45.3 %) and 88 (28.3 %) cases, respectively. On univariate analysis, adjuvant chemotherapy prolonged relapse-free survival (RFS) and overall survival (OS) in C-MET(+) patients (RFS p = 0.035; OS p = 0.013) but not in C-MET(-) patients. On multivariate analysis, adjuvant chemotherapy was a positive independent prognostic factor in C-MET(+) (RFS p = 0.013; OS p = 0.006) but not in C-MET(-) patients. In addition, univariate analysis showed no effect of EGFRmut status on RFS and OS after chemotherapy, whereas multivariate analysis revealed that adjuvant chemotherapy increased RFS in both EGFRmut(+) and EGFRmut(-) patients [EGFRmut(+) p = 0.033; EGFRmut(-) p = 0.030]. C-MET was a negative prognostic factor for RFS (p = 0.045) and OS (p = 0.007) in the EGFRmut(-) group but not in the EGFRmut(+) group, on multivariate analysis. CONCLUSIONS Our data indicate that patients with C-MET overexpression should be considered for adjuvant chemotherapy, and that C-MET negatively correlates with survival in patients with wild-type, but not mutant, EGFR.

Abstract
Targeted therapies have markedly improved the management of patients with advanced non-small-cell lung cancer (NSCLC), but their efficacy in localized NSCLC is less well established. The aim of this review is to analyze trials of targeted therapies in localized NSCLC. In patients with wild-type EGFR, tyrosine kinase inhibitors have shown no efficacy in Phase III trials. Few data are available for EGFR-mutated localized NSCLC, as routine biological profiling is not recommended. Available studies are small, often retrospectives, and/or conducted in a single-center making it difficult to draw firm conclusions. Ongoing prospective Phase III trials are comparing adjuvant tyrosine kinase inhibitor administration versus adjuvant chemotherapy. By analogy with the indication of bevacizumab in advanced NSCLC, use of antiangiogenic agents in the perioperative setting is currently restricted to nonsquamous NSCLC. Several trials of adjuvant or neoadjuvant bevacizumab are planned or ongoing, but for the moment there is no evidence of efficacy. Data on perioperative use of biomarkers in early-stage NSCLC come mainly from small, retrospective, uncontrolled studies. Assessment of customized adjuvant or neoadjuvant therapy in localized NSCLC (with or without oncogenic driver mutations) is a major challenge.

Abstract
BACKGROUND The prognostic value of epidermal growth factor receptor (EGFR) mutations in resected non-small cell lung cancer (NSCLC) remains controversial. We performed a systematic review with meta-analysis to assess its role. METHODS Studies were identified via an electronic search on PubMed, Embase and Cochrane Library databases. Pooled hazard ratio (HR) for disease-free survival (DFS) and overall survival (OS) were calculated for meta-analysis. RESULTS There were 16 evaluated studies (n = 3337) in the meta-analysis. The combined HR evaluating EGFR mutations on disease free survival was 0.96 (95% CI [0.79-1.16] P = 0.65). The combined HR evaluating EGFR mutations on overall survival was 0.86 (95% CI [0.72-1.04] P = 0.12). The subgroup analysis based on univariate and multivariate analyses in DFS and OS showed no statistically significant difference. There was also no statistically significant difference in DFS and OS of stage I NSCLC patients. CONCLUSION The systematic review with meta-analysis showed that EGFR mutations were not a prognostic factor in patients with surgically resected non-small cell lung cancer. Well designed prospective study is needed to confirm the result.

Abstract
BACKGROUND Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) show great efficacy in patients with advanced non-small cell lung cancer (NSCLC) with EGFR mutations. The efficacy and safety of gefitinib following adjuvant chemotherapy in patients with EGFR mutation are unknown. METHODS In this open-label, phase II study, patients with resected stage IIIA-N2 NSCLC harbouring EGFR mutations (either exon 19 deletion or L858R point mutation) were assigned randomly to receive pemetrexed (500 mg/m(2)) and carboplatin (AUC = 5), administered every 21 days for 4 cycles, followed with or without gefitinib (250 mg/day) for 6 months. The primary end point was disease-free survival (DFS). RESULTS From August 2008 to September 2011, 60 patients were included in our center. DFS was significantly longer among those who received pemetrexed and carboplatin (PC)-gefitinib than among those who received PC alone [hazard ratio (HR), 0.37; 95 % confidence interval (CI) 0.16-0.85; P = 0.014; median, 39.8 vs. 27.0 months]. The rates of 2-year DFS were 78.9 % in the PC-gefitinib group and 54.2 % in the PC alone group. The rates of 2-year overall survival (OS) were 92.4 % in the PC-gefitinib group and 77.4 % in the PC alone group (HR, 0.37; 95 % CI 0.12-1.11, P = 0.076). The most common adverse event was rash (43.3 %, 13/30) in the PC-gefitinib group and the administration of gefitinib following chemotherapy was well tolerated. CONCLUSIONS The administration of gefitinib following PC adjuvant therapy shows significant improvement in DFS in patients with resected stage IIIA-N2 NSCLC harbouring EGFR mutations.
