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.

Aim: This study aimed to investigate the prognostic value of peripheral naive and memory CD8+ and CD4+ T cells and other immune cells in patients with oligometastatic non-small-cell lung cancer (NSCLC) undergoing radiotherapy (RT). Methods: A total of 142 patients with oligometastatic NSCLC treated with RT were enrolled, and their blood samples were collected within 3 days before RT. Immune cells were identified by flow cytometry. Results: Patients with high levels of naive CD8+ T cells had longer overall survival (p = 0.004) and progression-free survival (p = 0.001) than those with low levels of naive CD8+ T cells. Multivariate analyses revealed that naive CD8+ T cells were independently correlated with overall survival (p = 0.019) and progression-free survival (p = 0.024). Conclusion: The results suggest that peripheral naive CD8+ T cells may be an independent prognostic indicator for patients with oligometastatic NSCLC undergoing RT.

Abstract Background Dissociated responses (DR) are phenomena in which some tumors shrink, whereas others progress during treatment of patients with cancer. The purpose of the present study was to evaluate the frequency and prognosis of DR in non-small cell lung cancer (NSCLC) patients treated with anti-program cell death-1/ligand 1 (anti-PD-1/L1) inhibitors. Methods This retrospective study included NSCLC patients who received anti-PD-1/L1 inhibitor as second- or later-line treatment. We excluded patients without radiological evaluation, including brain imaging within 28 days prior to the treatment, and those without measurable lesions. We evaluated all measurable lesions in each organ. We defined DR as a disease with some shrinking lesions as well as growing or emerging new lesions in patients who showed progressive disease (PD), according to the RECIST 1.1 at the initial CT evaluation. Cases not classified as DR were defined as ‘true PD’. Overall survival was compared between patients with DR and those with true PD using Cox proportional hazards models. Results The present study included 62 NSCLC patients aged 27–82 years (median: 65 years). DR and true PD were observed in 11 and 51 patients, respectively. Nivolumab, pembrolizumab, and atezolizumab were administered to 45, 7, and 10 patients, respectively. Median overall survival was significantly longer in patients with DR versus true PD (14.0 vs. 6.6 months; hazard ratio for death: 0.40; 95% confidence interval: 0.17–0.94). Conclusions The frequency of DR in NSCLC patients who showed PD to anti-PD-1/L1 was 17.7%. Patients with DR exhibited a relatively favorable prognosis.

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.

e21050 Background: Stereotactic body radiotherapy (SBRT) is a highly focused radiation treatment, which is now recommended to treat non-small cell lung cancer (NSCLC) patients with early stage disease. The purpose of this study is to evaluate the efficacy and toxicity of SBRT for early stage NSCLC patients with subclinical interstitial lung disease (ILD). Methods: One hundred and nine patients with early stage NSCLC were treated with SBRT between December 2011 and August 2016 in our institution; patients with subclinical (untreated and oxygen-free) ILD were treated with SBRT, while those with clinical ILD (post- or under treatment) were not. The median SBRT dose was 50 Gy in 5 fractions and the median biologically effective dose (BED; α/β = 10) was 100 Gy (range:72-119 Gy). The presence of subclinical ILD in the pre-SBRT CT findings was reviewed by two chest radiologists. The relationships among the efficacy, radiation pneumonitis (RP) and clinical factors were investigated. Results: Subclinical ILD was recognized in 38 (35%) of 109 patients. Grade 2–4 RP was recognized in 48 (44%) of 109 patients, no Grade 5 RP was happened. Grade 2–4 RP was observed in 17 (45%) of 38 patients with subclinical ILD. Subclinical ILD was not found to be a significant factor influencing Grade 2–4 RP; however, extensive RP beyond the irradiated field, including the contralateral lung, was recognized in only two patients who were both suffering from subclinical ILD, and the rate of extensive RP was significantly high in the patients with subclinical ILD. Dosimetric factors of the lungs (V5, V10, V20, MLD, V12.5, V13.5) were significantly associated with Grade 2–4 RP. The three-year overall survival and progression-free survival rates of all patients were 82.8% and 62.5%, respectively. No significant differences were seen in either overall survival or progression-free survival rates among the patients with ILD and those without ILD, or with RP and those without RP. Conclusions: Subclinical ILD was not found to be a significant factor for Grade 2–5 RP or clinical outcomes in early stage NSCLC treated with SBRT; however, uncommon extensive RP can occur in patients with subclinical ILD.

Abstract Background: In spite of the wide use of immune-checkpoint inhibitors (ICIs) in advanced or metastatic non-small cell lung cancer (NSCLC), whether ICIs or conventional chemotherapy is more effective still remains controversial. This study was conducted to evaluate the efficacy of giving patients programmed cell death 1 (PD-1), programmed cell death ligand 1 (PD-L1), or cytotoxic T-lymphocyte protein 4 (CTLA-4) alone or in their combination (PD-1/L1 + CTLA-4) versus simply applying chemotherapy in patients with advanced or metastatic NSCLC.Methods: This meta-analysis was conducted from PubMed, Web of Science, Medline, Embase, and the Cochrane Library up to March 2021 to identify relevant randomized controlled trials (RCTs). Primary endpoints were overall survival (OS) and progression-free survival (PFS). Secondary endpoint was adverse events (AEs). Results: The search process has identified 13 studies containing 7918 patients with advanced or metastatic NSCLC. The benefit of PD-1/L1 or CTLA-4 inhibitors alone or in combination compared with chemotherapy for advanced or metastatic NSCLC was elucidated in both overall survival (OS) [HR=0.75, 95%CI (0.70-0.80), P<0.001] and progression-free survival (PFS) [HR=0.83, 95%CI (0.73-0.95), P<0.001]. Sex is another vital factor that affects the efficacy of ICIs. Male [HR=0.71, 95%CI (0.63-0.81)] benefits more from ICIs than the female [HR 0.80, 95%CI (0.68-0.94)] in OS. Besides, ICIs were associated with fewer AEs compared to chemotherapy.Conclusion: PD-1/L1 or CTLA-4 inhibitors alone or in combination, with fewer AEs, was associated with significant improvements in terms of OS and PFS than chemotherapy in treatment of advanced or metastatic NSCLC.
