e21099 Background: Liver metastasis is one of the most reasons for the poor prognosis of patients with advanced lung cancer. Seeking for active and effective treatment measures is very important for these patients. At present, the first-line standard treatment of the advanced NSCLC with EGFR mutation is EGFR-TKIs monotherapy. However, its efficacy is poor in the advanced non-small cell lung cancer with EGFR mutation and liver metastases. The objective of this study is to evaluate the efficacy of EGFR-TKIs plus chemotherapy in patients with EGFR mutation of advanced non-small cell lung cancer with liver metastases. Methods: The clinical data of a total of 384 advanced NSCLC patients with EGFR mutation positive who were admitted to The Affiliated Cancer Hospital of Zhengzhou University/Henan Cancer Hospital from February 2017 to June 2020 were retrospectively analyzed. There were 75 patients with liver metastases. Patients were divided into two groups, and accepted EGFR-TKIs monotherapy or EGFR-TKIs plus chemotherapy, respectively. All patients treatment response were evaluated by the RECIST1.1 Response evaluation criteria in solid tumors.Progression free-survival (PFS) were also analyzed. Results: In the study, 75 patients were finally screened. There were 37 patients in the EGFR-TKIs monotherapy group and 38 patients in the TKI plus chemotherapy group. The median follow-up time was 23.0 months. At the latest follow-up date (2021-01-01), 57 patients had disease progression and 35 patients had died. Comparing with EGFR-TKIs monotherapy,the first-line PFS of EGFR-TKI plus chemotherapy group was longer, and the median PFS was 12.7 months VS 7.4 months (P = 0.018).The ORR of primary lung lesions was no significant difference between these two groups（65.8%VS 51.4% P = 0.204), and DCR (97.4% VS 94.6% P = 0.981) also had no difference between two groups（P > 0.05）. ORR of liver metastases in the EGFR-TKIs plus chemotherapy group was significantly higher than EGFR-TKIs monotherapy group ORR (65.8%VS 40.5%，P = 0.028). Conclusions: In advanced NSCLC patients with EGFR mutation and liver metastases, comparing with EGFR-TKIs monotherapy, taking EGFR-TKIs plus chemotherapy as first-line treatment had longer PFS, and better efficacy on liver lesions.

9011 Background: Pembrolizumab (pembro) is approved as first-line (1L) treatment for advanced NSCLC patients (pts) with PD-L1 tumor proportion score (TPS) ≥50% and as treatment for previously treated advanced NSCLC pts with PD-L1 TPS ≥1%. Here we present 3-y OS results for pts enrolled in KEYNOTE-001 (NCT01295827), the first trial evaluating pembro in advanced NSCLC pts. Methods: 550 pts received pembro 2 or 10 mg/kg Q3W or 10 mg/kg Q2W until intolerable toxicity, progression, or investigator or pt decision to withdraw. PD-L1 expression was assessed by IHC using the 22C3 antibody. Survival was assessed every 2 mo after treatment discontinuation. Results: 550 advanced NSCLC pts enrolled; 101 were first line (1L), and 449 were previously treated. As of the Sept 1, 2016, data cutoff, median follow-up duration was 34.5 mo (range, 25.7-51.5 mo); 8 (7.9%) 1L pts and 28 (6.2%) previously treated pts were still on treatment. 3-y OS was 26.4% (95% CI, 14.3%-40.1%) in 1L pts and 19% (95% CI, 15.0%-23.4%) in previously treated pts. 3-y OS rate and median OS by PD-L1 status are in the Table. Additional description of the pts with long-term survival, including updated safety data as well as 3-y OS by smoking history, histology, EGFRstatus, and prior radiation therapy, will be presented. Conclusions: Pembro provides promising long-term OS benefit for 1L and previously treated advanced NSCLC pts expressing PD-L1. The current data represent the longest efficacy and safety follow-up for pts with advanced NSCLC treated with pembro. Clinical trial information: NCT01295827. [Table: see text]

Background Circulating endothelial cells (CECs) reflect the neovascularization in the tumor mass. We therefore investigated the potential role of CEC kinetics after first-line chemotherapy in advanced non-small cell lung cancer (NSCLC) patients. Methods Peripheral blood samples were obtained from 45 healthy subjects and 51 naïve patients with advanced NSCLC. Quantification of CD146+ CECs was performed using immunomagnetic separation (IMS). Results Pretreatment and posttreatment CEC levels in NSCLC patients were significantly higher than in healthy subjects (p<0.0001). An objective response was achieved after chemotherapy with partial response (PR) or stable disease (SD) in 26 patients, whereas the remaining 25 patients had progressive disease (PD). Baseline CEC levels were significantly higher in PR/SD patients than in PD patients (p = 0.039). After chemotherapy, CEC count significantly decreased in PR/SD patients (p = 0.014) and increased in patients with PD (p = 0.019). Moreover, there was a significant difference in the percentage change of CEC counts between the 2 groups (p = 0.0016). No significant difference in the median progression-free survival and overall survival (OS) was observed between patients with high baseline CEC counts and those with low baseline CEC levels. However, patients with high percentage change in CEC count had longer OS than those with low percentage change after chemotherapy (p = 0.05). Conclusions Changes in CEC counts after chemotherapy reflect tumor response in advanced NSCLC patients. Moreover, high percentage changes in CEC counts after chemotherapy may predict longer OS in advanced NSCLC. High baseline CEC levels might be an indicator of tumor response in advanced NSCLC patients after first-line chemotherapy.

8066 Background: Platinum-based chemotherapy (CT) is the standard treatment for patients (pts) with advanced NSCLC, but the evidence of its efficacy among ECOG PS2 pts is weak, because these pts are usually excluded from clinical trials; concern exists about tolerability and feasibility of standard CT in these pts. No prospective randomized trial has tested the addition of cisplatin to single-agent CT in pts with advanced NSCLC and PS2. Methods: CAPPA-2 was a multicentre, randomized phase III study for first-line treatment of PS2 pts with advanced NSCLC. Patients, aged 18-70, were eligible if they had stage IV or IIIB with malignant pleural effusion or metastatic supraclavicular nodes (TNM VI ed.) and adequate organ function. Patients in standard arm received gemcitabine 1,200 mg/m2 dd1 and 8.Patients in experimental arm received cispaltin 60 mg/m2 d1 plus gemcitabine 1,000 mg/m2 dd1 and 8. All treatments were repeated q3w, up to 4 cycles, unless disease progression or unacceptable toxicity. Primary endpoint was overall survival (OS). To have 80% power of detecting hazard ratio (HR) 0.71, corresponding to an increase in median OS from 4.8 to 6.8 months, 285 deaths were required. Results: The study was stopped in June 2012 after the enrolment of 57 pts, due to the slow accrual and the report of positive results from a similar study. Median OS was 3.0 months with single-agent gemcitabine and 5.9 months with cisplatin + gemcitabine (HR 0.52, 95% CI 0.28-0.98, p=0.039). Combination CT produced longer PFS (median 1.7 vs. 3.3 months, HR 0.49, 95% CI 0.27-0.89, p=0.017) and higher response rate (4% vs. 18%, p=0.19), without substantial increase in toxicity. Conclusions: Addition of cisplatin to single-agent gemcitabine improves survival as first-line treatment of PS2 patients with advanced NSCLC. Clinical trial information: NCT00526643.
