8078 Background: Treatment of metastatic non-small cell lung cancer (NSCLC) has evolved over the last decade with the increased use of third-generation chemotherapy agents, established benefits from second-line chemotherapy, and the development of targeted agents. We conducted a study to evaluate whether these treatment advances translated into improved survival in a large registry database. Methods: The Surveillance Epidemiology and End Results (SEER) registry was queried for patients with NSCLC stage IV, aged 21 or older, and diagnosed between 1990 and 2005. Overall Survival (OS) rates were estimated by the Kaplan-Meier method and compared using log-rank test. Cox proportional hazard model was fitted to evaluate whether the diagnostic period is an independent predictor for OS. Demographic variables included period of diagnosis (1990–1993 or P1, 1994–1997 or P2, 1998–2001 or P3, and 2002–2005 or P4), age, gender, race, and histology. Results: There were 127,816 patients meeting eligibility criteria. Median age at presentation was 67 and most patients were male (58%), white (81%), and had adenocarcinoma (39%). Although there was no significant differences in OS between periods 1 and 2 (p = 0.18), there was a significant improvement from periods 2 to 3 (p < 0.001) and 3 to 4 (p < 0.001). 1-y and 2-y OS increased from 13.2% and 4.5% respectively in P1 to 19.4% and 7.8% respectively in P4. Predictive factors for improved survival in multivariate analyses included diagnostic period (p < 0.001), younger age (p < 0.0001), female gender (p < 0.0001), and non-black race (p < 0.0001). After adjusting for demographic factors, there were no significant differences in OS between adenocarcinoma and squamous cell from P1 to P3 (1990–2001). However, P4 showed a significant increase in OS for adenocarcinoma compared with squamous cell (p = 0.02). Conclusions: There has been a significant improvement in OS for stage IV NSCLC over the last 8 years. The recent differences in outcomes based on histology observed in P4 may reflect the increased activity of newer therapies in adenocarcinoma compared with squamous cell, including gefitinib and erlotinib. No significant financial relationships to disclose.

Purpose MDM2 is a negative regulator of p53. The MDM2 309T/G polymorphism has been associated with differential MDM2 expression levels and inhibition of the p53 pathway. We hypothesized that the MDM2 G/G genotype may be associated with worse survival outcomes in lung cancer, especially in squamous cell cancers where p53 abnormalities are more common. Patients and Methods We evaluated the relationship between MDM2 polymorphism status and overall survival (OS) among patients with early-stage non–small-cell lung cancer (NSCLC) treated with surgical resection at Massachusetts General Hospital from 1992 to 2000. Kaplan-Meier methods and the log-rank test were used to compare survival by polymorphism status. Cox proportional hazards models were used to adjust for possible confounding variables. Results There were 383 patients in the analysis. In the early-stage population as a whole, the G/G genotype seemed to be associated with worse OS on adjusted analysis (adjusted hazard ratio = 1.57; 95% CI, 1.03 to 2.40; P = .04). Among patients with squamous histology, OS was significantly worse among those with the G/G genotype (P = .0001 by log-rank test), with 5-year survival rates among the genotypes of 59% for T/T, 53% for T/G, and 7% for G/G. Conclusion Our findings suggest that the G/G genotype of the MDM2 polymorphism is associated with worse OS among early-stage NSCLC patients, particularly those with squamous cell histology.

Background: Five-year overall survival (OS) for patients with stage IV non-small cell lung cancer (NSCLC) is a dismal 1%. However, approximately 7% have limited or solitary metastases, including to the adrenal gland. Radical treatment of these oligometastases (OM) could increase local control and improve OS. Our objective was to critically analyze data describing aggressive treatment of adrenal OM secondary to NSCLC. Methods: A literature search examining English publications describing surgery or radiotherapy (RT) was performed, supplemented by searching reference lists. Case reports of three or fewer patients, and articles from which NSCLC- or adrenal-specific clinical outcomes could not be abstracted, were excluded. Results: Twenty-nine studies met eligibility criteria (521 patients), 26 retrospective. No publications directly compare modalities. Four surgery studies described contemporaneous patients treated with palliative chemotherapy (CH) alone. Reported median OS ranged from 9.5–64 months after adrenalectomy, 8–23 months after RT, and 6–8.5 months after CH. Local failure after surgery was 14%, with response rates after RT 57–75%. Both appear well-tolerated. Conclusions: In patients with an adrenal OM secondary to NSCLC, aggressive treatment should be considered. However, due to the paucity of high quality evidence, it is unclear at present whether this approach alters the natural history of the disease.

e15031 Background: Stage IV lung cancer is the most advanced lung cancer state accompanied by metastasized to the area around the lungs or distant major organs. The most common type of lung cancer is non-small cell lung cancer, which is more aggressive and may spread quickly due to organ-specific complex networks such as lymph and major blood vessels. Thus, only precise diagnostic strategy approaches will determine the effectiveness of the actual and successful clinical treatment. Until a recent date, Immunohistochemistry (IHC) for programmed death-ligand 1(PD-L1) test is the only available biomarker test that purpose diagnostics (CDx) and guide the treatment with immune checkpoint inhibitors in NSCLC. Methods: Given that CDx strategy, tissue biopsy has inevitable limitations, including patient risk, repetitive examination, sample preparation, sensitivity, and accuracy. For this reason, our research team contrived the best strategy for biomarker, PD-L1-specific CTCs in stage IV NSCLC group (N = 30) compared to pulmonary inflammatory patient groups (N = 30) CytoGen Smart biopsy platform. Herein, we removed false-positive cells for the first strategy of distinguishing between lymphoid/myeloid cells and the enriched-CTCs. And the second strategic approach is to calculate the pure CTCs (without false-positive cells) and then CTPS) as measured by the PD-L1 expression among pure-CTCs. That application is the percentage of viable CTCs showing partial or complete stained cells at the deducted cut-off value in each fluorescence, respectively. Results: Consequently, we demonstrated over 80% of the concordance rate between VENTANA PD-L1(SP263) and DAKO PD-L1(SP263) assay tested by the PD-L1 expression on stage IV NSCLC in tissue and pure-CTCs based CTPS from the blood. In contrast, pure-CTCs based CTPS in the pulmonary inflammatory group were all negative (recorded as zero). Conclusions: Conclusively, this study implicates that pure-CTCs based CTPS could be deployed for innovative diagnosis strategies as alternatives for tissue biopsy. Our clinical study's data suggested that the possibility for prompt decision for diagnosis and gain powerful insights to guide the personalized treatment in NSCLCs.

59 Background: The use of comprehensive genomic profiling (CGP) in cancer patients could lead to additional enrollment in clinical trials that study novel genetic biomarkers, potentially reducing treatment costs for payers and improving health outcomes for patients. Our objective was to estimate the number of additional clinical trials in which patients with non-small cell lung cancer (NSCLC) could potentially enroll due to the use of CGP vs. a comparator panel of 50 genes or less. Methods: Clinical trials in NSCLC that started between 2015 - 2020 were identified from the Aggregate Analysis of ClinicalTrials.gov (AACT) database. Trials with unknown status or study sites outside the United States only were excluded. We abstracted information on required genetic alterations based on the study eligibility criteria. We calculated the incremental number of trials available to patients due to results generated by CGP (FoundationOne CDx, 324 genes) vs. a commercially available comparator panel that was 50 genes or less (Oncomine Dx Target Test, 23 genes) by phase and calendar year. The additional trials were characterized by disease severity, type of therapy, and setting. Results: Enrollment eligibility was dependent on genetic variant status in 35% (250/709) of all identified NSCLC trials. There were 29 (248 vs. 219) additional clinical trials available to patients through the use of CGP, 12% of all gene-specific trials for NSCLC. We identified 45 uses of genetic markers in the 29 additional clinical trials. The most frequent genetic marker in the incremental trials was microsatellite instability, accounting for 44% of all identified markers (20/45). The incremental number of trials available to patients due to the use of CGP did not vary significantly over time but varied by phase – most of the additional clinical trials were in phase 1 or 2 (28/29, 97%). Most of the incremental trials were in metastatic disease (22/29, 76%) and were conducted in academic or advanced community settings (18/29, 62%). The most frequently studied type of intervention in these studies was targeted monotherapy (8/29, 28%), followed by immuno-monotherapy (7/29, 24%). Conclusions: Clinical trials in NSCLC initiated over the past 5 years have consistently included CGP-specific genes or markers in eligibility criteria. Patients with NSCLC have the potential to benefit from the use of CGP as compared to smaller gene panels through improved access to clinical trials.[Table: see text]
