e19164 Background: The epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) bring the best result to EGFR-mutation positive non-small cell lung cancer patients, but most lead to drug resistance. These acquired resistances are associated with T790M mutation or Met amplification, HGF expression. To assess whether affects overall survival in these patients, we did a retrospective study comparing survival outcomes in 2nd EGFR-TKI treated patients with controls without 2nd EGFR-TKI screened during the same time period. Methods: We examined overall survival in thirty-two of 52 patients with advanced, EGFR-mutation-positive NSCLC who treated 1st EGFR-TKI (gefitinib) from January 2009 to December 2012. We identified 16 patients who were given 2nd EGFR-TKI (erlotinib) after failure of the initial gefitinib treatment (retreatment group) with 16 patients who were not given 2nd EGFR-TKI but given only chemotherapy (control group), 20 patients who might treat with 2nd EGFR-TKI or chemotherapy at that time were excluded in progress after failure of the initial gefitinib treatment. To assess differences in overall survival, we assessed subsets of clinically comparable 2nd EGFR-TKI retreatment group. Results: Among 16 patients who were given 2nd EGFR-TKI, retreatment group who were given one or two cytotoxic chemotherapy from 1st EGFR-TKI to 2nd EGFR-TKI, median overall survival from initiation of the diagnosis with advanced IIIB/IV stage or surgical recurrent NSCLC was 24.2 months. 16 patients of control group who were given from second to seven line cytotoxic chemotherapy, overall survival was 15.8 months (p=0.021). Retreatment group who were given 2nd EGFR-TKI was significantly longer than control group in EGFR mutation positive patients. Response rate and disease control rate with 2nd EGFR-TKI retreatment are 12.5% and 31.3%. Conclusions: In patients with advanced, EGFR mutation positive NSCLC, retreatment group who were given 2nd EGFR-TKI therapy was associated with improved survival compared with control group who were given only cytotoxic chemotherapy.

8521 Background: EGFR-TKI has been widely used in the treatment for advanced non-small cell lung cancer (NSCLC). Previous studies, such as the EVIDENCE study and the ADAURA study, have confirmed that patients with EGFR-mutated NSCLC could benefit from adjuvant EGFR-TKI treatment. However, the optimal duration time of adjuvant EGFR-TKIs has not been clearly defined. Methods: In this multicenter, randomized, phase 2 trial, eligible patients with II-IIIA stage EGFR mutation-positive NSCLC after R0 resection were randomized in 1:1 to receive adjuvant icotinib for 1 year (group A) or 2 years (group B). The primary endpoint was disease-free survival (DFS). Results: Between September 2013, and September 2018, 109 patients from 8 centers were enrolled in this study, among whom 55 were randomized to group A and 54 to B. As of August 24, 2020 (data cutoff), the median follow-up was 44.1 months (95%CI 37.1-49.9), 31 (56%) of 55 patients in the 1-year group and 25 (46%) of 54 patients in the 2-year group had DFS events. The median DFS was 48.92 months (95%CI 33.15, 70.11) in 2-year group and 32.89 month (95%CI 26.61, 44.78) in 1-year group, respectively. 2-year icotinib significantly prolonged DFS (HR 0.521, 95%CI 0.278, 0.976; p = 0.039). OS events were observed in 20 patients, the OS was not mature yet. Icotinib was re-given for 32 patients with disease recurrence or metastasis as first-line treatment, objective response occurred in 66.7% of 30 patients with measurable disease. Treatment-related adverse events were recorded in 41 of 55 (75%) patients in 1-year group and 36 of 54 (67%) patients in 2-year group, and grade 3 or 4 treatment-related adverse events occurred in 4 (7%) of 55 patients in the 1-year group versus 3 (6%) of 54 in the 2-year group, respectively. No treatment-related deaths or interstitial lung disease were reported. Conclusions: 2-year adjuvant treatment with icotinib resulted in a significantly lower risk of recurrence than 1-year adjuvant icotinib in patients with stage II-IIIA NSCLC positive EGFR mutations and was not associated with increased toxic effects. Clinical trial information: NCT01929200.

8502 Background: Median Overall survival (mOS) of stage IIIA resected NSCLC was 59.4 months (m) in CTONG 1104 adj gefitinib and 26.2m in SAKK neoadjuvant chemo trial. EMERGING-CTONG1103 showed neo-adjuvant/adjuvant erlotinib treatment significantly improved progression-free survival (PFS) vs standard doublet chemotherapy in patients (pts) with epidermal growth factor receptor ( EGFR) mutation-positive resectable stage IIIA (N2) non-small-cell lung cancer (NSCLC). Here, we present the final overall survival (OS) results from the study. Methods: This was a multicenter (17 centers in China) phase II randomized controlled trial of erlotinib(E)versus gemcitabine plus cisplatin (GC) as neoadjuvant/adjuvant therapy in pts with stage IIIA-N2 NSCLC with EGFR mutations in exon 19 or 21. From Dec 2011 to Dec. 2017, 386 pts sites were screened and 72 pts were randomly assigned to neoadjuvant/adjuvant E arm (N = 37) or GC arm(N = 35). Patients received erlotinib 150 mg/d (neoadjuvant therapy, 42 days; adjuvant therapy, up to 12 months) or gemcitabine 1,250 mg/m2 plus cisplatin 75 mg/m2 (neoadjuvant therapy, two cycles; adjuvant therapy, up to two cycles). Assessments were performed at 6 weeks and every 3 months postoperative. The primary end point was objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1; secondary end points were pathologic complete response, downstaging rates of pathological lymph nodes, PFS, OS, safety, and tolerability. Data cut-off date was January, 29 2021. Results: With a median follow-up of 62.5 months, the median OS was 42.2months based on 47 (65.3%) events in ITT whole population. The mOS was 42.2m in E and 36.9m in GC (HR 0.83, 95%CI 0.47-1.47, p = 0.513). The 3-,5-year OS rate were 58.6%, 40.8% in E and 55.9%, 27.6% in GC respectively (p3-y = 0.819, p5-y = 0.252). All predefined subgroups including age, gender, EGFR mutation type had no significant difference in statistics between two arms. Subsequent treatments (ST) especially targeted therapy contributed most to OS (HR = 0.35,95% CI 0.18- 0.70). Median OS of pts receiving ST was 45.8m (n = 38), 34.6m in other treatment (n = 12), 24.6m in without ST (n = 15). For E mOS were 46.4 (n = 15; target therapy), 42.2m (n = 8; other) and 24.6m (n = 9; without, p = 0.021), for GC 42.6 (n = 23; target therapy), 30.1m (n = 4;other) and 24.6m(n = 6; without, p = 0.130). The RR was 53.3%, DCR 93.3%, mPFS 10.9m and mPPS 21.9m for patients with rechallenged EGFR TKI in E arm (n = 15). No novel unexpected SAE was observed during follow up. Conclusion: Erlotinib as neoadjuvant/adjuvant therapy for resected N2 NSCLC was feasibility and had a promising OS. The PFS survival advantage of E did not translate to OS difference in EMERGING trial (NCT01407822). Clinical trial information: NCT01407822.

Purpose Ifosfamide, carboplatin, etoposide, and vincristine, alone and in combination, are highly active against small-cell lung cancer (SCLC). This trial was designed to investigate whether survival could be improved by a regimen of all four drugs (ICE-V) compared with standard chemotherapy in patients with SCLC and good performance status, and to assess the patients’ quality of life (QL). Patients and Methods Patients were randomly assigned to receive six cycles of either ICE-V at 4-week intervals without dose reduction or standard chemotherapy administered according to local practice. The recommended standard control regimens were cyclophosphamide, doxorubicin, and etoposide; and cisplatin and etoposide. Results A total of 402 patients were randomly assigned, and 350 (87%) patients have died. Overall survival was longer in the ICE-V group (hazard ratio, 0.74; 95% CI, 0.60 to 0.91; P = .0049), median survival was 15.6 months in the ICE-V group and 11.6 months in the control group, and 2-year survival rates were 20% and 11%, respectively. There was no evidence that the relative survival benefit for ICE-V was less in extensive-stage than in limited-stage patients. An increased rate of septicemia was reported in the ICE-V group (15% v 7% in the control group), but this did not result in an increase in reported treatment-related deaths (four patients [2%] in both groups). The findings on QL were broadly similar in both groups, with some benefit in favor of ICE-V. Conclusion Compared with standard chemotherapy, the ICE-V regimen improves overall survival without QL penalties, despite an increased but manageable level of toxicity.
