8501 Background: Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor is a standard of care for EGFR mutation-positive, untreated metastatic non-small cell lung cancer (NSCLC). However, the efficacy and safety of adjuvant gefitinib for patients with completely resected lung cancer harboring EGFR mutation over cisplatin-based adjuvant chemotherapy were not known in 2011 when this study was initiated. Methods: From September 2011 to December 2015, we randomly assigned 234 patients with completely resected, EGFR mutation-positive (exon 19 deletion or L858R), stage II–III NSCLC to receive either gefitinib (250 mg, once daily) for 24 months or cisplatin (80 mg/m2 on day 1) plus vinorelbine (25 mg/m2 on days 1 and 8) (cis/vin) every 3 weeks for four cycles. The primary endpoint was disease-free survival (DFS) according to a central review in the intent-to-treat (ITT) population. Results: Two patients in the gefitinib arm withdrew consent and were excluded from the ITT population. No treatment-related deaths were seen in the gefitinib arm, but three treatment-related deaths were reported in the cis/vin arm. Median duration of follow-up was 71 months. Median DFS was numerically longer in the gefitinib arm (36 months) than in the cis/vin arm (25.2 months). However, Kaplan-Meier curves began to overlap around 5 years after surgery, and no significant difference in DFS was seen, with a hazard ratio (HR) of 0.92 (95% confidence interval (CI), 0.67–1.28; P = 0.63). Overall survival was also not significantly different (median not reached in either arm). Five-year survival rates for gefitinib and cis/vin arms were 78.0% and 74.6%, respectively, with an HR for death of 1.03; 95%CI, 0.65–1.65; P = 0.89. Exploratory subset analysis revealed that patients ³70 years old in the gefitinib arm (n = 19/27 with G to cis/vin) survived longer than those in the cis/vin arm (HR 0.31; 95%CI, 0.10–0.98; P = 0.046). Conclusions: Adjuvant gefitinib appeared to prevent early relapse, but did not significantly prolong DFS or OS in patients with completely resected stage II–III, EGFR-mutated NSCLC. The apparent non-inferiority of DFS/OS may justify the use of adjuvant gefitinib in selected subset of patients, especially those deemed unsuitable for cis/vin adjuvant therapy.

Introduction: Osimertinib is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved as first-line therapy for advanced EGFR-mutated non-small cell lung cancer (NSCLC). Some osimertinib-related interstitial lung diseases (ILDs) were shown to be transient, called transient asymptomatic pulmonary opacities (TAPO)—clinically benign pulmonary opacities that resolve despite continued osimertinib treatment—and are not associated with the clinical manifestations of typical TKI-associated ILDs. Methods: In this multicentric study, we retrospectively analyzed 92 patients with EGFR-mutated NSCLC treated with osimertinib. Computed tomography (CT) examinations were reviewed by two radiologists and TAPO were classified according to radiologic pattern. We also analyzed associations between TAPO and patients’ clinical variables and compared clinical outcomes (time to treatment failure and overall survival) for TAPO-positive and TAPO-negative groups. Results: TAPO were found in 18/92 patients (19.6%), with a median follow-up of 114 weeks. Median onset time was 16 weeks (range 6–80) and median duration time 14 weeks (range 8–37). The most common radiologic pattern was focal ground-glass opacity (54.5%). We did not find any individual clinical variable significantly associated with the onset of TAPO or significant difference in clinical outcomes between TAPO-positive and TAPO-negative groups. Conclusions: TAPO are benign pulmonary findings observed in patients treated with osimertinib. TAPO variability in terms of CT features can hinder the differential diagnosis with either osimertinib-related mild ILD or tumor progression. However, because TAPO are asymptomatic, it could be reasonable to continue therapy and verify the resolution of the CT findings at follow-up in selected cases.

PurposeIn the phase III INTEREST trial, 1,466 pretreated patients with advanced non–small cell lung cancer (NSCLC) were randomly assigned to receive gefitinib or docetaxel. As a preplanned analysis, we prospectively analyzed available tumor biopsies to investigate the relationship between biomarkers and clinical outcomes.MethodsBiomarkers included epidermal growth factor receptor (EGFR) copy number by fluorescent in situ hybridization (374 assessable samples), EGFR protein expression by immunohistochemistry (n = 380), and EGFR (n = 297) and KRAS (n = 275) mutations.ResultsFor all biomarker subgroups analyzed, survival was similar for gefitinib and docetaxel, with no statistically significant differences between treatments and no significant treatment by biomarker status interaction tests. EGFR mutation–positive patients had longer progression-free survival (PFS; hazard ratio [HR], 0.16; 95% CI, 0.05 to 0.49; P = .001) and higher objective response rate (ORR; 42.1% v 21.1%; P = .04), and patients with high EGFR copy number had higher ORR (13.0% v 7.4%; P = .04) with gefitinib versus docetaxel.ConclusionThese biomarkers do not appear to be predictive factors for differential survival between gefitinib and docetaxel in this setting of previously treated patients; however, subsequent treatments may have influenced the survival results. For secondary end points of PFS and ORR, some advantages for gefitinib over docetaxel were seen in EGFR mutation–positive and high EGFR copy number patients. There was no statistically significant difference between gefitinib and docetaxel in biomarker-negative patients. This suggests gefitinib can provide similar overall survival to docetaxel in patients across a broad range of clinical subgroups and that EGFR biomarkers such as mutation status may additionally identify which patients are likely to gain greatest PFS and ORR benefit from gefitinib.

Abstract Background: The prognosis of non-small-cell lung cancer (NSCLC) with brain metastases is very poor. Currently, therapeutic methods for this patient population include whole-brain radiation therapy (WBRT), surgery, radiosurgery and systemic treatment. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) could be effective on cerebral metastases of mutated NSCLC. However, which EGFR-TKIs is more appropriate is still unknown. Methods: We conducted a retrospective analysis of advanced NSCLC patients with brain metastases for EGFR targeted therapy from November 2013 to April 2018 at Dongguan People’s Hospital, Southern Medical University, China. A total of 43 patients were recruit in this study. Among them, 21 cases received icotinib (125 mg, thrice a day) and 22 cases received gefitinib (250 mg, once a day) until disease progression or unacceptable toxicity. The primary end point of this study was intracranial PFS (iPFS). The relationships between therapeutic arms and patients characteristics were performed using Pearson’s chi-square test or Fisher’s exact test. The differences in PFS among the two arms were analyzed using Kaplan-Meier curves and log rank tests. Results: There was no significant difference of intracranial ORR (66.6% versus 59.1%, P =0.62) and DCR (85.7% versus 81.8%, P =0.73) between the two arms. The median intracranial PFS (iPFS) for icotinib and gefitinib arms were 8.4 months (95% CI, 5.4 to 11.3 months) and 10.6 months (95% CI, 6.3 to 14.8 months), respectively (P =0.17). Adverse events of the two study arms were generally mild. None of the patients experienced dose reduction of EGFR-TKIs. Conclusions: Our study showed that icotinib and gefitinib had similar efficacy for brain metastasis of EGFR mutated NSCLC. Large randomized studies are suggested to further illuminate the effect of these two EGFR-TKIs on cerebral lesions of NSCLC.

Background: Sarcopenia, reduced skeletal muscle mass, is associated with frailty, injuries, and mortality. The purpose of this study was to evaluate the impact of computed tomography–determined sarcopenia on surgical complications and outcomes after resection of non-small cell lung cancer. Methods: For a total 272 non-small cell lung cancer patients that underwent surgery between 2011 and 2016, cross-sectional area of muscle at the third lumbar vertebra (L3) was retrospectively measured using preoperative chest computed tomography images. Sarcopenia was defined as an L3 muscle index of <55 cm2/m2 for men and of <39 cm2/m2 for women. Clinical characteristics, postoperative complications, disease-free survival, and overall survival of patients with or without sarcopenia were compared. Results: A total of 60.3% ( n = 164) were male, and mean patient age was 62.9 ± 9.6 years. The prevalence of sarcopenia was 22.4% for all study subjects, 32.9% for men, and 6.5% for women. No significant difference was observed between patients with or without sarcopenia in terms of intensive care unit or hospital stay ( p = 0.502 and p = 0.378, respectively), and the presence of sarcopenia was not associated with postoperative complications. Furthermore, no significant difference was observed between the 3-year disease-free survival rate (74.3% vs 66.7%, p = 0.639) or 3-year overall survival rate (83.9% vs 87.7%, p = 0.563) of patients with or without sarcopenia. Conclusion: Sarcopenia as determined by preoperative computed tomography does not appear to have a negative impact on surgical outcome or overall survival for resected non-small cell lung cancer patients.

e21015 Background: Mutations in the Epidermal Growth Factor Receptor (EGFR) predict a better response to tyrosine kinase inhibitors compared to platinum-based chemotherapy in advanced non-small cell lung cancer (NSCLC). Previous studies in caucasian population have reported a frequency of EGFR mutation of 10-15%. The aim of this study is to analyze the prevalence of EGFR mutations in caucasian smoker patients with NSCLC. Methods: Prospective mutation testing in NSCLC patients included in our institution since October 2010 to January 2012 was performed on DNA obtained from available tumor tissue and cytologic samples, using ARMS-scorpion TheraScreen EGFR 29 Mutation Test Kit (Qiagen). Results: From 218 consecutive NSCLC diagnoses, 18 (8.25%) patients showed EGFR mutations: 6 (33.3%) exon 19 deletions, 9 (50%) exon 21 mutations (7 cases L858R and 2 cases L861Q) and 3 (16.6%) exon 20 insertions. In the EGFR-mutated patients, 13 (72.25%) were never-smoker and 5 (27.7%) were smoker (3 current-smoker and 2 former-smoker). The EGFR-mutated smoker population showed the following characteristics: 3 female, 2 male; 4 adenocarcinoma, one squamous cell carcinoma; 3 stage IV, 2 stage IA at diagnosis; 1 (20%) case EGFR deletion exon 19, 1 (20%) case insertion exon 20 and 3 patients (60%) mutation exon 21 (2, L858R and 1, L861Q). Conclusions: The EGFR mutation rate in NSCLC smoking patients in our referral area is superior (27.7%) than previously reported, reinforcing the importance of including EGFR mutation testing in NSCLC smoking population for the correct management of these patients.
