e18237 Background: Non-Small Cell Lung Cancer (NSCLC) is the most common malignancy worldwide and the leading cause of malignancy-related mortality in the United States. The state of Maine in particular, has one of the highest rates of lung cancer in the country. Methods: We reviewed all NSCLC patients (adenocarcinoma (AC) and squamous cell (SC) histology) diagnosed between January 2017 and June 2018 at Northern Light Cancer Institute. 261 patients with clinical follow-up were identified. We correlated their clinical characteristics with molecular abnormalities identified by Next Generation Sequencing (NGS) and Fluorescence in situ hybridization, PD-L1 status by immunohistochemistry, disease-free and overall survival. Results: 210 patients had AC and 51 SC. They were evenly split between men and women. The median age at diagnosis was 68 years. 99% of patients were Caucasian. 15 patients were never smokers, the rest were equally divided between active and previous smokers. 44% had early stage disease (I/II) and 56% had late stage disease (III/IV) on presentation. 36.4% had a PD-L1 high status. The frequencies of the molecular aberrations identified in AC and SC are listed in the table below: Treatment differed by stage, including surgery/Radiation +/- adjuvant chemotherapy for early stage disease, definitive chemo-radiation followed by immunotherapy for stage III disease. Stage IV patients were treated with immunotherapy, combination chemo-immunotherapy, targeted therapy, palliative radiation and hospice referral. After a median follow-up of 10.6 months, overall survival (OS) was 66%. Disease free survival (DFS) was 33%. Using univariate (chi-square), multivariate (logistic regression) and Kaplan-Meier (log rank) analyses, we identified that in addition to a high clinical stage, which was associated with shorter OS and DFS, high PD-L1 status, and the presence of p53 mutation, were independent predictors of shorter OS, and p53 mutation of shorter DFS. Conclusions: NGS-based molecular testing deployed in real-time non-academic setting proved to be a valuable tool to identify therapeutic and prognostic targets in NSCLC. Besides those endorsed by the NCCN guidelines, p53 mutation is a common abnormality associated with adverse outcomes. While high PD-L1 expression is a desirable immunotherapy marker, its presence also predicted adverse overall outcomes in our patients.[Table: see text]

Small-cell lung cancer (SCLC) is one of the most aggressive tumors, with a rapid growth and early metastases. Approximately 5% of SCLC patients present with early-stage disease (T1,2 N0M0): these patients have a better prognosis, with a 5-year survival up to 50%. Two randomized phase III studies conducted in the 1960s and the 1980s reported negative results with surgery in SCLC patients with early-stage disease and, thereafter, surgery has been largely discouraged. Instead, several subsequent prospective studies have demonstrated the feasibility of a multimodality approach including surgery before or after chemotherapy and followed in most studies by thoracic radiotherapy, with a 5-year survival probability of 36–63% for patients with completely resected stage I SCLC. These results were substantially confirmed by retrospective studies and by large, population-based studies, conducted in the last 40 years, showing the benefit of surgery, particularly lobectomy, in selected patients with early-stage SCLC. On these bases, the International Guidelines recommend a surgical approach in selected stage I SCLC patients, after adequate staging: in these cases, lobectomy with mediastinal lymphadenectomy is considered the standard approach. In all cases, surgery can be offered only as part of a multimodal treatment, which includes chemotherapy with or without radiotherapy and after a proper multidisciplinary evaluation.

Abstract Erythropoietin (EPO) and its cell surface receptor EPOR have been shown to be expressed in many different types of cancer such as breast, prostate and head and neck cancer. The objectives of this study were to determine the frequency of EPO and EPOR expression in non-small cell lung cancer (NSCLC) and to characterize the association of EPO and EPOR expression with clinical and histological features of early stage NSCLC and its outcome. Seventy three patients with primary NSCLC from the Durham Veterans Affairs Hospital who underwent primary resection of their tumors were included in the study after providing informed consent in accordance with a research protocol approved by the Institutional Review Board at Durham Veterans Administration Medical Center. The median follow up period was 3.8 years. At the time of last follow-up 24 patients (33%) had recurred and 38 patients (52%) had died. Histologically, 38 primary tumors (52%) were squamous cell carcinomas, 27 (37%) were adenocarcinoma (ADC) and 8 (11%) were other types of NSCLC. Thirty-three patients (45%) had T1 lesions, 37 (51%) had T2 and 3 patients (4%) had T3 tumors. Nodal stage was N0 in 59 patients (81%) and N1 in 14 patients (19%). Fifty-six patients (77%) had pathologic stage I disease and 17 patients (23%) has stage II disease. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded tumors from each patient using monoclonal antibodies against EPO and EPOR. The expression was determined using a semi-quantitative scoring scale taking into consideration both the intensity and the percentage of tumor cells staining positive. Weak expression in ≤ 5% of tumor cells was considered negative. EPO was expressed in 60 of the 73 tumors (82%) and frequently exhibited a focal pattern of staining. EPOR was expressed in 60 tumors (82%) with predominantly cytoplasmic localization except for several cases where membrane staining of EPOR was also observed. Both EPO and EPOR were expressed in 55 (75%) tumors. We also characterized the expression of hypoxia-inducible factor-1a (HIF1a), the hypoxia regulated protein CA-IX, and to determine the Ki-67 proliferation index and microvessel density (MVD) using CD31 immunostaining. Patients with adenocarcinoma had lower EPOR expression in comparison to patients with other histologic subtypes (Wilcoxon test, P=0.03). EPOR expression was not associated significantly with other clinical or histological parameters or outcome. Patients with early nodal stage (N0) and overall pathologic stage (stage I) disease had significantly higher EPO expression (Wilcoxon test, P=0.01 and P=0.02, respectively). High MVD levels were associated with high EPO expression (Wilcoxon test, P=0.01) but EPO was not associated with any other histologic variables. Interestingly, higher EPO expression was associated with significantly better recurrence-free survival (Logrank test, P=0.006) and overall survival (P=0.008). Cox proportional hazard regression analysis revealed that high EPO expression was associated with better survival (P<0.05). In multivariate analysis, EPO was not an independent prognostic factor. In conclusion, these data in our cohort of patients demonstrate that - EPO and EPOR are expressed with high frequency in primary NSCLC with the majority of tumors co-expressing both EPO and EPOR and - High EPO expression in tumor cells is associated with better recurrence-free and overall survival.

9123 Background: Metastatic non-small cell lung cancer (mNSCLC) has classically been treated with platinum-doublet chemotherapy. Recent studies have established immunotherapy as an integral part of therapy for mNSCLC without targetable mutations. There are limited data on the role of consolidative thoracic radiotherapy (TRT) for patients with mNSCLC in the immunotherapy-era. A secondary analysis of KEYNOTE-001 showed significant improvement in overall survival in patients who received radiotherapy with pembrolizumab compared to patients not previously receiving radiotherapy. Methods: We queried the National Cancer Database (NCDB) for patients with metastatic presentation, stage IVA/IVB non-small cell lung cancer between the ages of 18-90 years treated between 2012-2017 with a combination of chemotherapy, immunotherapy, and thoracic radiotherapy. Patients with unknown treatment status, follow up time, or vital status were excluded. Overall survival (OS) was estimated using the Kaplan-Meier method and compared between treatment groups utilizing log-rank testing. A 3:1 nearest-neighbor propensity-score matching was performed utilizing clinical and demographic covariates to reduce the impact of potential confounders of overall survival on the probability of receipt of TRT. Cox proportional hazards regression was used to identify predictors of overall survival. Results: A total of 81,382 patients were identified that met inclusion criteria. The median age was 68 (18-90) years. The majority of patients (n = 51,681, 64%) had chemotherapy, while 7,929 (10%) patients received immunotherapy, and 15,984 (20%) received TRT. The median follow-up was 6.18 (range 0-76.9) months. For the entire cohort of patients receiving immunotherapy, 2 year OS was 29.4% with TRT compared to 32.7% without. Following propensity matching by age, sex, race, and comorbidity score, a total number of 4,264 patients receiving immunotherapy were matched. The 2 year OS was 27.7% in patients receiving TRT and immunotherapy vs. 22.2% in patients with immunotherapy alone (p = 0.004). On multivariable analysis receipt of TRT was a significant predictor of OS after adjustment for age, race, comorbidity score, sex, and median income (p = 0.0003, HR 0.87, 95% CI 0.80 - 0.94). For patients receiving BED10 > 39 Gy (equivalent to 30 Gy in 10 fractions), 2 year OS was significantly improved at 37.0% vs 18.1% (p < 0.0001). Conclusions: In patients with mNSCLC, the addition of TRT to immunotherapy is associated with improved overall survival at 2 years. Receipt of a higher BED10 is associated with further improved survival. Selection of mNSCLC patients receiving immunotherapy for TRT approaching definitive doses warrants further investigation. Data from prospective, randomized trials may better elucidate this benefit and identify a potential mechanism.

Background: This study aims to identify the prognostic factors in Stage IIIA non-small cell lung cancer and to investigate whether there was a significant difference in terms of overall survival and disease-free survival among the subgroups belonging to this disease stage. Methods: Between January 2010 and December 2018, a total of 144 patients (125 males, 19 females; median age 60 years; range, 41 to 80 years) who were operated for non-small cell lung cancer in our clinic and whose pathological stage was reported as IIIA were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, histopathological diagnosis, the standardized uptake value of the mass on positron emission tomography-computed tomography, tumor diameter, type of surgery, lymph node metastasis status, visceral pleural invasion, and overall and disease-free survival rates were recorded. Results: The median survival was 39 (range, 27.8 to 46.1) months and the five-year overall survival rate was 28%. The mean tumor diameter was 4.3±2.7 cm. The median disease-free survival was 37 (range, 28.1 to 48.6) months and the five-year disease-free survival rate was 26.9%. In the multivariate analysis, overall survival and disease-free survival in T2N2M0 subgroup were significantly worse than the other subgroups. The other poor prognostic factors of survival were the standardized uptake value of the tumor, pneumonectomy, and histopathological subtypes other than squamous cell carcinoma and adenocarcinoma. Parietal pleural invasion was significantly associated with worse disease-free survival rates. Conclusion: Our results showed that there may be significant survival differences between subgroups created by tumor histopathology, lymph node invasion and the type of surgery in a heterogeneous lung cancer stage.

Background We investigated whether all size-based pathological T4N0–N1 non-small cell lung cancer patients with tumors at any size >7 cm had the same outcomes. Methods We reviewed non-small cell lung cancer patients with tumors >7 cm who underwent anatomical lung resection between 2010 and 2016. A total of 251 size-based T4N0–N1 patients were divided into two groups based on tumor size. Group S ( n = 192) included patients with tumors of 7.1–9.9 cm and Group L ( n = 59) as tumor size ≥10 cm. Results The mean tumor size was 8.83 ± 1.7 cm (Group S: 8.06 ± 0.6 cm, Group L: 11.3 ± 1.6 cm). There were 146 patients with pathological N0 and 105 patients with pathological N1 disease. Mean overall survival and disease-free survival were 64.2 and 51.4 months, respectively. The five-year overall survival and disease-free survival rates were 51.2% and 43.5% (five-year OS; pT4N0:52.7%, pT4N1:47.9%, DFS; pT4N0:44.3%, pT4N1: 42.3%). No significant differences were observed between T4N0 and T4N1 patients in terms of five-year OS or DFS ( p = 0.325, p = 0.505 respectively). The five-year overall survival and disease-free survival rates were 52% and 44.6% in Group S, and 48.5% and 38.9% in Group L. No significant difference was observed between the groups in terms of five-year overall survival or disease-free survival ( p = 0.699, p = 0.608, respectively). Conclusions Above 7 cm, any further increase in tumor size in non-small cell lung cancer patients had no significant effect on survival, confirming it is not necessary to further discriminate among patients with tumors in that size class.
