Background. We retrospectively compared the incidence of isolated elective nodal failure (IENF) and toxicity rates and survival outcomes after elective nodal irradiation (ENI) versus involved-field RT (IFRT) by employing the propensity score matching (PSM) methodology in stage IIIB/C inoperable non-small-cell lung cancer (NSCLC) patients treated with definitive concurrent chemoradiotherapy (C-CRT). Methods. Our PSM examination included 1048 stage IIIB/C NSCLC patients treated with C-CRT from January 2007 to December 2016: a total dose of 66 Gy (2 Gy/fraction) radiotherapy and 1–3 cycles of platinum-based doublet chemotherapy concurrently. The primary and secondary endpoints were the IENF and toxicity rates and survival outcomes after ENI versus IFRT, respectively. Propensity scores were calculated for each group to adjust for confounding variables and facilitate well-balanced comparability by creating 1 : 1 matched study groups. Results. The median follow-up was 26.4 months for the whole study accomplice. The PSM analysis unveiled 1 : 1 matched 646 patients for the ENI (N = 323) and IFRT (N = 323) cohorts. Intergroup comparisons discovered that the 5-year isolated ENF incidence rates (3.4% versus 4.3%; P=0.52) and median overall survival (25.2 versus 24.6 months; P=0.69), locoregional progression-free survival (15.3 versus 15.1 months; P=0.52), and progression-free survival (11.7 versus 11.2 months; P=0.57) durations were similar between the ENI and IFRT cohorts, separately. However, acute grade 3-4 leukopenia (P=0.0012), grade 3 nausea-vomiting (P=0.006), esophagitis (P=0.003), pneumonitis (P=0.002), late grade 3-4 esophageal toxicity (P=0.038), and the need for hospitalization (P<0.001) were all significantly higher in the ENI than in the IFRT group, respectively. Conclusion. Results of the present large-scale PSM cohort established the absence of meaningful IENF or survival differences between the IFRT and ENI cohorts and, consequently, counseled the IFRT as the elected RT technique for such patients since ENI increased the toxicity rates.

Background: Stereotactic body radiotherapy (SBRT) in ultra-central (UC) lung tumors, defined in the presence of planning target volume (PTV) overlap or direct tumor abutment to the central bronchial tree or esophagus, may be correlated to a higher incidence of severe adverse events. Outcome and toxicity in oligometastatic (≤3 metastases) non-small-cell lung cancer (NSCLC) patients receiving SBRT for UC tumors were evaluated. Methods: Oligometastatic NSCLC patients treated with SBRT for UC were retrospectively reviewed. Local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS) and overall survival (OS) were calculated. Incidence and grade of toxicity were evaluated. Statistical analysis was performed to assess the impact of clinical and treatment-related variables on outcome and toxicity occurrence. Results: Seventy-two patients were treated to a median biologically effective dose (BED) of 105 (75–132) Gy10. Two-year LC, DMFS, PFS, and OS were 83%, 46%, 43%, and 49%. BED>75 Gy10 was correlated to superior LC (p = 0.02), PFS (p = 0.036), and OS (p < 0.001). Grade ≥3 toxicity rate was 7%, including one fatal esophagitis. No variables were correlated to DMFS or to occurrence of overall and grade ≥3 toxicity. Conclusions: SBRT using dose-intensive schedules improves outcome in NSCLC patients. Overall toxicity is acceptable, although rare but potentially fatal toxicities may occur.

Immunotherapy with immune checkpoint inhibitors (ICIs) has changed the therapeutic management of advanced non-small cell lung cancer (aNSCLC) over the last decade. However, there is an unmet need for clinically useful biomarkers in this patient subgroup. The aim of this study was to combine baseline clinical characteristics of aNSCLC patients, in the form of a scoring system, and to investigate its predictive and prognostic value in NSCLC patients treated with ICIs. A total of 112 patients with advanced (stages IIIA to IV) NSCLC, treated with nivolumab or pembrolizumab, were enrolled in this study. Patras Immunotherapy Score (PIOS) was developed based on four of the studied parameters (performance status (PS), body mass index (BMI), age, and lines of treatment (LOT), which were incorporated into our formula (PS × BMI/ LOT × age). PIOS score was strongly associated with best overall responses (BOR), with those patients having benefit/good response (stable disease (SD) or partial (PR) or complete response (CR), achieving a higher score compared to patients who developed progressive disease (PD) (p < 0.001). Furthermore, PIOS score was associated with progression-free survival (PFS), since high-score patients had longer PFS (p < 0.001, hazard ratio (HR) = 0.469). Moreover, PIOS was associated with post-immunotherapy overall survival (OS), with high-score patients having improved OS (log-rank p = 0.019). This study suggests that a combination of baseline parameters, which give rise to PIOS score, may predict the best response of NSCLC patients treated with anti-program cell death -1 (PD-1) monotherapy as well as it may have a potent prognostic value for PFS and post immunotherapy OS.

e21636 Background: Afatinib is an irreversible ErbB family blocker, which is approved for the treatment of advanced non-small cell lung cancer (NSCLC) patients with activating EGFR mutations. Here we report the final results of the prospective non-interventional study (NIS) GIDEON, which was initiated to investigate the efficacy and tolerability of afatinib in the daily clinical routine in Germany. Methods: EGFR-mutated NSCLC patients were treated with afatinib according to label until progression, death or discontinuation. Efficacy (progression-free survival (PFS) rate at 12 months, objective response rate, ORR; disease control rate, DCR; progression-free survival, PFS and overall survival, OS) was prospectively assessed by investigators. Data about tolerability were collected during routine treatment. Results: In total, 161 patients were enrolled at 41 sites in Germany, 152 patients received at least one dose of afatinib (treated set; TS) and 146 patients were treated according to the protocol (PPS). The majority of patients for the entire TS had exon 19 deletions (64.5%), followed by L858R point mut. (22.4%) and uncommon mut. (exon 18-21 point mut.; 13.1%). The primary objective was PFS-rate at 12 months, which was 50.2% in the PPS. Median PFS amounted to 12.2 months. ORR and DCR were 74.6% and 91.5% in the PPS, respectively. Median OS was 30.4 months with 1- and 2-year survival rates of 79.1% and 57.7%, respectively. Among pat. with uncommon EGFR-mut., the 12-months PFS rate was 40.2% with a mPFS of 10.7 months. ORR and DCR were 83.3% and 91.7%, respectively. The most frequent documented adverse drug reactions (ADRs) were diarrhea and rash/acne with 13.8% and 7.2% of grade 3 but no grade 4 or higher. Conclusions: Afatinib is a standard therapy for patients with activating EGFR mut. in Germany. The final results of this prospective NIS confirm the robust clinical data for afatinib in the clinical routine setting, including patients with uncommon exon 18-21 point mutations. Clinical trial information: NCT02047903.

18177 Background: The efficacy and safety of a combined regimen of topotecan and etoposide was tested in patients with relapsed or refractory small-cell lung cancer. Methods: From October 2003 to May 2005, 23 patients who have failed to the previous irinotecan and platinum chemotherapy received intravenous topotecan 1mg/m2 (day 1–5) followed by intravenous etoposide 80mg/m2 (day 1–3). Treatment was repeated every 21 days for a maximum of 6 cycles. Results: Twelve patients were refractory to first-line chemotherapy. Seventeen patients (73.9%) were male and the median age was 63 years. ECOG performance status was 0–1 in 13 (56.5%) patients. The median cycles of chemotherapy was 3. Twenty one patients were assessable for response evaluation. The overall response rate was 17.4% (0 CR, 4 PR, 7 SD, 10 PD) under the intent-to-treat analysis. After a median follow- up of 20.8 months, median progression free survival was 4.7 months and median overall survival was 9.5 months. The estimated 1-year survival rate was 38.7%. In sensitive relapsed patients, 2 achieved tumor response and median progression free survival and overall survival were 5.5 months and 14.5 months. All patients were assessable for toxicity and major toxicities were myelosuppression. Grade 3/4 neutropenia and thrombocytopenia occurred in 18 (78.3%) and 12 (52.2%) patients, respectively. Grade 3/4 febrile neutropenia occurred in 2 patients (8.7 %) and infection in 3 patients (13.0%). There was one treatment-related death due to pneumonia. Conclusions: This salvage regimen failed to demonstrate a considerable response rate compared with monotherapy for relapsed or refractory SCLC. However, the combination of topotecan and etoposide could be further studied for sensitive relapsed patients pretreated with irinotecan and platinum No significant financial relationships to disclose.

11535 Background: Epidermal growth factor receptor (EGFR) inhibitors such as erlotinib and gefitinib are routinely used in the treatment of non-small cell lung cancer (NSCLC). Monitoring of EGFR mutations in circulating tumor DNA (ctDNA) derived from plasma has been proposed as an alternative for repeated tumor biopsies. Our aim was to investigate the dynamics of ctDNA in a cohort of NSCLC patients and explore the roles of EGFR driver and resistance mutations in predicting disease progression and progression free survival (PFS). Methods: NSCLC patients treated with either erlotinib or gefitinib as first-line anti-EGFR therapy were included. Clinical data was collected retrospectively from medical records. Plasma samples collected as part of routine care were analyzed. First DNA was isolated from plasma using the QIAsymphony SP (Qiagen). Then EGFR driver (L858R and exon 19 deletions) and resistance (T790M) mutations were quantified using the X100 Droplet Digital PCR and analyzed using QuantaSoft software (Bio-Rad). The dynamics of ctDNA mutations over time and the relationship between copy numbers and progression free survival were explored. Results: 68 NSCLC patients and 249 plasma samples (1-13 per patient) were included in the analysis. In 33 patients, the T790M mutation was detected. The median (range) T790M concentration in these samples was of 7.3 (5.1 - 3688.7) copies/mL. In 30 patients, the L858R or exon 19 deletion driver mutations were found in median concentrations of 11.7 (5.1 – 12393.3) and 27.9 (5.9 – 2896.7) copies/mL, respectively. Using local polynomial regression, the copies/mL of EGFR driver mutations increased several weeks prior to progression on standard response evaluation. In Kaplan-Meier analysis, patients with a detectable T790M mutation during the first 8 weeks of treatment had a shorter PFS (7.6 versus 14.4 months, p < 0.01, log-rank test). Conclusions: Early detection of the T790M mutation in plasma ctDNA is related to poor PFS. Furthermore, an increase in the copies/mL of the EGFR driver mutation over time may predict clinical progression.

8527 Background: It is unknown which regimen is the best in concurrent chemoradiotherapy (CCRT) of locally advanced non-squamous non-small cell lung cancer (NSCLC). Our previous randomized phase Ⅱ study, NJLCG0601, showed that chemoradiotherapy with uracil/tegafur (UFT) and cisplatin achieved promising efficacy with acceptable toxicities. In this trial, this regimen was compared to a regimen with pemetrexed and cisplatin for stage Ⅲ non-squamous NSCLC. Methods: Patients with inoperable stage Ⅲ non-squamous NSCLC were randomized to UFT 400 mg/m2 on days 1–14 and 29–42, and cisplatin 80 mg/m2 on days 8 and 36 (UP), or pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 on days 1, 22, and 43 (PP). Involved-field radiotherapy (IFRT) was administered from day 1 to a total dose of 66 Gy radiotherapy in 33 fractions. Consolidation chemotherapy after CCRT was not planned for this study. The primary endpoint was 2-year overall survival (OS), with expected rates of 55% and a lower limit of 35% (alfa 0.05, beta 0.2). Secondary endpoints were the objective response rate (ORR), progression-free survival (PFS), OS, and toxicity profile. Results: From November 2010 to June 2017, 86 patients were enrolled from 11 institutions. Of the 85 eligible patients, the rate of 2-year OS was 78.6% (95% CI: 62.8–88.3%) in the UP arm and 85.5% (95% CI: 70.5–93.2%) in the PP arm. The ORR was 76.7% in the UP arm and 81.0% in the PP arm. With a median follow-up of 54 months, median PFS and OS were 12.3 and 64.2 months in the UP arm, and 26.2 months and not reached in the PP arm, respectively. Grade 3/4 febrile neutropenia was more frequent in the UP arm than in the PP arm (14.0%, 2.0%, respectively). Grade 3/4 pneumonitis occurred in 7.0% and 4.8% of patients in UP and PP arms, respectively. Conclusions: Both regimens with IFRT achieved the expected 2-year survival rate. PP had more favorable results than UP in terms of OS and PFS. We selected the PP arm for the next step.

e21202 Background: Increased systemic inflammatory state and increased inflammation within tumor micro-environment (TME) have been associated with a worse prognosis and lower responsiveness to immune checkpoint inhibitors (ICI). Systemic inflammatory immune index (SII) reflects the changes in the systemic inflammatory matrix. Studies have shown the association of SII with cancer survival and treatment outcomes. We aim to study the effect of SII on treatment outcomes in non-small cell lung cancer (NSCLC) patients being treated with ICI. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs (pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab) alone or in combination with chemotherapy. SII is the product of platelets multiplied by neutrophils divided by lymphocytes. Baseline and 8-week SIIs were obtained. Radiographic response, duration of radiographic response (date of best response to radiographic progression), overall survival (OS), and progression-free survival (PFS) were evaluated. A high SII was defined as a value greater than the median SII. Cox regression univariate and multivariate analyses were performed. Logistic regression, t-test, and Chi-square tests were applied. Results: Overall, 81% patients had adenocarcinoma and 19% patients had squamous, adenosquamous or large cell carcinoma. The majority of the patients were female (56.2% vs. 43.8%). Median SII at baseline was 1335. The objective response rate (ORR) was 45.1%. The disease control rate was 75.8%. The ORR was 51% in patients receiving ICI first-line compared to 35% in those who received ICI as a second-line therapy. At baseline, there was no difference in the mean SII between responders and non-responders (2146.2 vs. 1917.5, P = 0.5); however at 8 weeks, the mean SII was significantly lower in responders compared to non-responders (1198.8 vs. 2880.2, P = 0.02). A total of 15 (10.9%) patients were found to have pseudoprogression or mixed response on follow-up imaging. Among these, 11(73.3%) patients had low SII at 8 weeks (P = 0.04). The median OS was significantly higher in patients with low SII at baseline (29.6 months vs. 10.1 months, P = 0.001 95% CI 10.6 – 22.1). Similarly, there was a significant difference in median PFS in patients with low SII (14.6 months vs. 6.7 months, P = 0.002, 95% CI 5.6 – 11.6). There was no correlation between high or low SII on the incidence of immune-related adverse events. Conclusions: SII may have significant impact on OS and PFS and could be serially monitored to assess the response to ICI. A low SII may help to differentiate pseudoprogression vs. true progression. Prospective studies are needed to validate these findings. Further, it will be interesting to see if SII could be incorporated into predictive models to determine the duration of cytotoxic therapy in selected patients.

e20679 Background: Nivolumab (Nivo) is applicable for all metastatic or unresectable non-small cell lung cancer (NSCLC), however only some patients benefit from it. Therefore, identifying biomarkers predicting efficacy is a crucial topic in the “real world’’ setting. We conducted a retrospective study to analyze the impact of metastatic status on the effect of Nivo in NSCLC patients. Methods: This is a retrospective multicenter study conducted by the three medical centers in Japan. All patients treated with Nivo from January 2016 to July 2016 in these centers were retrospectively reviewed. We collected clinical data including age, sex, smoking history, performance status (PS), and metastatic cites (lymph nodes: lym, liver, brain, bone, pleural effusion, and intrapulmonary metastasis: lung) at the time of starting Nivo treatment. We investigated relationship between metastatic sites and progression free survival (PFS) of Nivo. Patients were followed-up until 30th September 2016. Results: Two hundred and one patients treated with Nivo were enrolled. At the time of administration of Nivo, median age was 68 years old, 137 patients were male, 155 patients had history of smoking status, 152 patients were PS 0 or 1, and 46 patients had squamous cell carcinoma (SQ). For all participants, median PFS was 2.5 months. In univariate analysis, female (hazard ratio (HR): 1.43, 95% confidence interval (CI): 1.02-2.00; p = 0.036), never-smoker (HR: 1.51 , 95% CI: 1.05 – 2.17; p = 0. 0262), PS 2 or more (HR: 1.68, 95% CI: 1.17-2.41; p = 0.0045), metastasis to liver (HR: 2.02, 95% CI: 1.30-3.15; p = 0.0015), brain (HR: 1.42, 95% CI: 0.99-2.03; p = 0.0574), bone (HR: 1.42, 95% CI: 1.01-1.98; p = 0.0642), lung (HR: 1.57, 95% CI: 1.13-2.20; p = 0.0076), and malignant pleural effusion (HR: 1.47, 95% CI: 1.06-2.04; p = 0.0195) had significantly correlated with poor PFS. In multivariate analysis, liver metastasis (HR: 1.59, 95% CI: 0.97-2.61; p = 0.0642) and malignant pleural effusion (HR: 1.47, 95%CI: 1.04–2.07; p = 0.0294) had significantly correlated with poor PFS. Conclusions: Liver metastasis and malignant pleural effusion were independent poor prognostic factors of Nivo treatment in NSCLC patients. (UMIN-ID: UMIN000025908)
