Abstract OBJECTIVES Although the standard treatment for pathological N2 (pN2) non-small-cell lung cancer (NSCLC) patients is definitive chemoradiation, surgery can be beneficial for resectable pN2 disease. Herein, we report the long-term clinical outcomes of upfront surgery followed by adjuvant treatment for selected patients with resectable pN2 disease. METHODS We performed a retrospective analysis of clinical outcomes for patients with pN2 disease who underwent surgery as the first-line therapy. Multivariable Cox regression analysis was used to identify the significant factors for overall survival (OS) and recurrence-free survival. RESULTS From 2004 to 2015, a total of 706 patients with pN2 NSCLC underwent complete anatomical resection at our institution. The patients’ clinical N stages were cN0, 308 (43.6%); cN1, 123 (17.4%) and cN2, 275 (39.0%). Adjuvant chemotherapy, radiotherapy and chemoradiotherapy were administered to 169 (23.9%), 115 (17.4%) and 299 patients (42.4%), respectively. With a median follow-up of 40 months, the respective median time and 5-year rate of OS were 52 months and 44.7%. According to subdivided pN2 descriptors, the median OS time was 80, 53 and 37 months for patients with pN2a1, pN2a2 and pN2b, respectively. Adjuvant chemotherapy was a significant prognostic factor for both OS [hazard ratio (HR) 0.39, 95% confidence interval (CI) 0.28–0.52; P < 0.001] and recurrence-free survival (HR 0.42, 95% CI 0.30–0.58; P < 0.001). CONCLUSIONS Upfront surgery followed by adjuvant therapy for resectable N2 disease showed favourable outcomes compared to those reported in previous studies. Adjuvant chemotherapy is essential to improve the prognosis for patients undergoing upfront surgery for N2 disease.

e20542 Background: Anaplastic lymphoma kinase (ALK) inhibitors show high clinical efficacy in patients with ALK-positive advanced non-small cell lung cancer (NSCLC). However, the long-term clinical outcomes remain unknown. Methods: We retrospectively reviewed medical records of patients with ALK inhibitor-naïve ALK-positive advanced NSCLC who initiated alectinib or crizotinib therapy at the Shizuoka Cancer Center between June 2010 and December 2011. Results: This retrospective study included 14 patients (male/female, 5/9; PS 0/1, 6/8; adenocarcinoma/adenosquamous carcinoma, 13/1; smoker/never smoker, 8/6; brain metastasis presence/absence, 5/9; number of prior chemotherapy regimens 0/1/≥2, 1/7/6; alectinib/crizotinib, 4/10) with a median age of 55 years (range, 28-71). At the data cut-off (January 16, 2017), three patients were still receiving first ALK inhibitors (alectinib in two patients and crizotinib in one). One patient requested the discontinuation of alectinib therapy after five years. One patient discontinued crizotinib therapy due to unacceptable toxicity. Nine patients discontinued first ALK inhibitors due to disease progression. The overall response rate was 78.6% with complete response in two patients (14.3%), partial response in nine (64.3%), stable disease in one (7.1%), and progressive disease in two (14.3%). The median progression-free survival (PFS) for all 14 patients was 15.3 months, and the five-year PFS rate was 35.7%. The five-year PFS rates in patients treated with alectinib and crizotinib were 75.0% and 20.0%, respectively. The median overall survival (OS) for all 14 patients was 36.8 months, and the five-year OS rate was 42.9%. The five-year OS rates in patients treated with alectinib and crizotinib were 75.0% and 30.0%, respectively. Conclusions: ALK inhibitors showed favorable long-term clinical outcomes in patients with ALK inhibitor-naïve ALK-positive advanced NSCLC, especially in patients treated with alectinib.

Abstract Objectives This study aimed to determine the characteristics, ground glass opacity ratio and prognosis of patients with clinical N0 non-small cell lung cancer tumours exceeding 30 mm in size. Methods Patients with clinical N0 non-small cell lung cancer and total tumour size >30 mm on preoperative computed tomography who underwent complete resection with lobectomy between January 2007 and December 2017 were included. The patients were divided into three groups: pure solid tumour, low ground glass opacity ratio (1–39%) tumour and high ground glass opacity ratio (≥40%) tumour. The cut-off line was determined based on the recurrence rate for every 10% ground glass opacity ratio. Results Among the 227 study patients, 129 (56.8%) had a pure solid tumour, 54 (23.8%) had a low ground glass opacity ratio tumour and 44 (19.4%) had a high ground glass opacity ratio tumour. Three-year recurrence-free survival was significantly shorter in patients with a pure solid tumour (57.4%) than in patients with a low ground glass opacity ratio (74.5%; P = 0.009) or a high ground glass opacity ratio tumour (92.1%; P < 0.001). Multivariable analysis showed that ground glass opacity ratio was a significant independent prognostic factor for recurrence-free survival (hazard ratio, 0.175; P = 0.037). Conclusion Pure solid tumours comprised a large proportion of non-small cell lung cancer tumours >30 mm in size and their prognosis was poor. The presence of ground glass opacity and their relative proportion affect prognosis in patients with clinical N0 non-small cell lung cancer tumours >30 mm in size, similar to those with small-sized tumours.

Purpose Our previous work evaluated individual prognostic and predictive roles of TP53, KRAS, and EGFR in non–small-cell lung cancer (NSCLC). In this analysis, we explore the prognostic and predictive roles of TP53/KRAS and TP53/EGFR comutations in randomized trials of adjuvant chemotherapy versus observation. Patients and Methods Mutation analyses (wild-type [WT] and mutant) for TP53, KRAS, and EGFR were determined in blinded fashion in multiple laboratories. Primary and secondary end points of pooled analysis were overall survival and disease-free survival. We evaluated the role of TP53/KRAS comutation in all patients and in the adenocarcinoma subgroup as well as the TP53/EGFR comutation in adenocarcinoma only through a multivariable Cox proportional hazards model stratified by trial. Results Of 3,533 patients with NSCLC, 1,181 (557 deaths) and 404 (170 deaths) were used for TP53/KRAS and TP53/EGFR analyses. For TP53/KRAS mutation status, no prognostic effect was observed ( P = .61), whereas a borderline predictive effect ( P = .04) was observed with a deleterious effect of chemotherapy with TP53/KRAS comutations versus WT/WT (hazard ratio, 2.49 [95% CI, 1.10 to 5.64]; P = .03). TP53/EGFR comutation in adenocarcinoma was neither prognostic ( P = .83), nor significantly predictive ( P = .86). Similar results were observed for both groups for disease-free survival. Conclusion We could identify no prognostic effect of the KRAS or EGFR driver and TP53 tumor suppressor comutation. Our observation of a potential negative predictive effect of TP53/KRAS comutation requires validation.
