A growing body of evidence shows improved overall survival and progression-free survival after thermal ablation in non-small cell lung carcinoma (NSCLC) patients with a limited number of metastases, combined with chemotherapy or tyrosine kinase inhibitors or after local recurrence. Radiofrequency ablation and microwave ablation are the most evaluated modalities, and target tumor size <3 cm (and preferably <2 cm) is a key factor of technical success and efficacy. Although thermal ablation offers some advantages over surgery and radiotherapy in terms of repeatability, safety, and quality of life, optimal management of these patients requires a multidisciplinary approach, and further randomized controlled trials are required to help refine patient selection criteria. In this article, we present a comprehensive review of available thermal ablation modalities and recent results supporting their use in oligometastatic and oligoprogressive NSCLC disease along with their potential future implications in the emerging field of immunotherapy.

Abstract Background: This study was designed to evaluate the treatment effect of S-1 following PEM-containing treatment. Methods: This retrospective study included patients with advanced (c-stage III or IV, UICC 7th) or recurrent NSCLC who received S-1 monotherapy following the failure of previous PEM-containing chemotherapy at 6 hospitals in Japan. Primary endpoint: Overall response rate (ORR). Secondary endpoint: Disease control rate (DCR), time to treatment failure (TTF), progression-free survival (PFS), and overall survival (OS). Results: A total of 53 NSCLC patients met the criteria. Forty-six patients had adenocarcinoma (88.7%) and no patients had squamous cell carcinoma. Thirty-one patients (58.5%) received the standard S-1 regimen and 18 patients (34.0%) received the modified S-1 regimen. ORR was 1.9% (95% confidential interval (CI): 0.00-10.1%). Median TTF, PFS, and OS were 65 days, 84 days, and 385 days, respectively. Conclusion: Although there were several limitations in this study, the ORR of S-1 after PEM in patients with non-SQ NSCLC was low compared to the historical control. It might be one of the choices to avoid S-1 treatment in PEM-treated patients who need tumor shrinkage.

AimsAnaplastic lymphoma kinase (ALK) rearranged non-small cell lung carcinoma (NSCLC) is a distinct molecular subtype and rapid approval of ALK tyrosine kinase inhibitors (TKIs) has necessitated rapid and sensitive diagnostic modalities for the detection of this alteration. Gene rearrangements can be identified using many techniques including fluorescence in situ hybridisation (FISH), reverse transcriptase-PCR, next-generation sequencing (NGS) and immunohistochemistry (IHC) for fusion oncoprotein expression. We aimed to determine the concordance between IHC, FISH and NGS for ALK biomarker detection, and determine differences in sensitivity, and survival outcomes.MethodsWe analysed the concordance between IHC using D5F3 monoclonal antibody, FISH (break-apart) and NGS using a custom panel containing 71 different ALK variants.ResultsAmong 71 cases included in this study, FISH was evaluable in 58 cases. The concordance of ALK IHC with FISH was 75.9% and that with NGS was 84.5%. The sensitivities of FISH and NGS were 75.6% and 87.5%, respectively. The median progression-free survival of ALK IHC-positive and FISH-negative group was 5.5 months and that of both positive was 9.97 months.ConclusionAlthough NGS offers a better throughput and visualisation, IHC still remains the quintessential screening tool in upfront diagnosis of ALK rearranged NSCLC.

The use of tyrosine kinase inhibitors (TKIs) in the treatment of solid tumors is the expected standard of care for many types of tumors. Since the description of signal transduction pathways, followed by the development of small molecules designed to inhibit those pathways, there has been significant improvement not only in progression-free survival and overall survival but also in aiming toward chemotherapy-free treatment of solid tumors to maximize quality of life. This article reviews available TKIs and discusses toxicity, dosing, and resistance.

3055 Background: Acquired ALK resistance mutations (mut.) are the main mechanism of tyrosine kinase inhibitor (TKI) resistance (30-50%). While next-generation TKIs are more active on mut. than earlier TKIs, compound ALK resistance are associated with failure to next-generation TKIs. We evaluated the clinical utility of detecting ALK resistance mutations in blood to predict TKI efficacy. Methods: ALK positive advanced NSCLC pts were prospectively enrolled between Oct. 2015 and Aug. 2018 in 8 French institutions. Prospective samples were collected; ctDNA was analyzed by amplicon-based Inivata InVisionFirst-Lung. Results: A total of 101 pts with advanced ALK positive NSCLC were enrolled and 328 samples collected. In samples collected at TKI failure (N=74), we detected 9 single and 7 complex (≥2) ALK resistance mut. (22%), associated with EML4-ALK variant 3 (38%) vs. variant 2 (13%) vs. variant 1 (none); 30% had other somatic mut. (mainly TP53 and KRAS, PI3KCA, MET, etc.). No mutations were detected in 48% of samples (ctDNA neg). ALK mut. were more frequent after 2nd/3rd generation TKI (43% post-lorlatinib (7), 29% post-2nd gen. (31), 11% post-crizotinib (36)). ALKG1202R was the most common, as single (n=3) or complex mut. (n=4). The median overall survival (mOS) was 100.4 mo. (95% CI 41.9-158.9) and the median progression free-survival (mPFS) to subsequent line was 2.8 mo. (0.7-4.9). Patients with ctDNA neg had mOS of 105 mo. (39.3-172.1) vs. 58.5 mo. (33.1-84.0) if ≥1 ALK mut. vs. 44.1 mo. (20.0-68.2) if others ( P=0.001). Pts with the complex ALK mut. had worse OS compared to singles ALK mut. (mOS 26.9 mo. vs. 58.5 mo., P=0.001); ALK complex mut. were associated with poor efficacy to subsequent therapy (PFS <3 mo. in 57%; no cases with PFS >6 mo.) vs. single mut., with longer PFS (PFS >6 mo. in 56%). Detectable ALKG1202R mut. were associated with shorter median OS (58.3 mo.; 7.9-109.1) vs. overall population; 86% of cases developed rapid PD (PFS <3mo.) to subsequent therapy with only one durable response to lorlatinib (PFS >6mo.). Conclusions: The absence of ctDNA mutations at TKI failure was associated with prolonged OS, whereas complex ALK mutations at TKI failure may predict resistance to subsequent therapy. Larger and specifically designed studies should be performed to validate these findings.

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have demonstrated improved progression-free survival benefits and decreased treatment-related side effects, and therefore are now considered first-line of treatment of EGFR mutated, metastatic non-small cell lung carcinoma (NSCLC). Cryptococcal endocarditis is an extremely rare clinical entity with only seven reported cases in the literature. Prior cases were seen in patients with a history of rheumatic heart disease or prior valve replacement surgery. Little is known regarding the natural history and optimal management of Cryptococcal endocarditis, given the limited available data. We present a case of Cryptococcal endocarditis and meningitis in a patient with metastatic NSCLC receiving targeted therapy with an EGFR-TKI with no history of significant cardiac disease.

e18114 Background: Previous exploratory analysis of EGFR status in tumor samples from five LATAM countries suggested that frequency of mutations lies between that of Asian and Caucasian populations and therefore support the genetic heterogeneity of NSCLC around the world. Methods: We analyzed the EGFR sequence of tumor samples from advanced stage NSCLC patients previously participated in the CLICaP registry. We compared the outcomes (overall and progression free survival) of 175 patients (from Argentina, Colombia and México) with an activating EGFR mutation with 414 subjects without this condition. Results: Mutations were more frequent in women (57,1%), in patients who had never smoked (67,4%), and in those with adenocarcinomas (89,4%) (P<0,002 for all comparisons). The mutations were deletions in exon 19 (58,3%) and L858R (36%). Median progression-free survival and overall survival for 175 patients who received tyrosine-kinase inhibitors (TKIs) were 13-mo (95%CI 11,2-14,8) months and 36-mo (95%CI 25,4-46,5), respectively. TKIs produced higher response rates (used as first or second line therapy) in the EGFR mutation-positive patients (70,8% vs. 29,2%; P<0,001), as well as improved PFS (13,0 vs. 3,0; P<0,001). OS is significantly different between treatment groups (36 vs. 14; P<0,001). Conclusions: The analysis of a large comparative registry of Latin-American EGFR mutated and wild type patients confirms the results of individual clinical trials previously published.

e19036 Background: Pulmonary sarcomatoid carcinomas (SC) account for about 0.4% of non-small cell lung carcinoma. These tumors have a poor prognosis due to high aggressiveness and maybe chemotherapy (CT) resistance. Methods: From 1995 to 2012, all consecutive patients with SC from 7 French hospitals and who underwent a 1st-line chemotherapy were included. Clinical characteristics and effect of CT (best response by RECIST 1.1 and progression-free survival [PFS]) as well as overall survival (OS) were collected. Results: Ninety-seven patients were included. Mean age was 62±1 years, 70% were men, 84% smokers, 84% symptomatic, 25% had a stage III and 75% a stage IV disease. At 1st-line, 73% received a platinum-based CT and 27% received a non-platinum-based CT. Progression (PR), stable disease (SD) and response (RR) rates were 69, 14.5 and 16.5%, respectively. For patients with platinum-based CT, PR, SD and RR rates were 69, 11 and 20%, respectively. RR rate was higher for platinum- than for non-platinum-based CT (p=0.018). Median PFS and OS were 2.0 mo [1.8 ; 2.3] and 6.7 mo [5.1 ; 8.2], respectively. No statistical difference in PFS (p=0.264) and OS (p=0.096) was observed between platinum and non-platinum based CT. In multivariate analysis, factors associated with better OS were disease control (HR=0.36 [0.21;0.59]), platinum-based CT (HR=0.92 [0.85;0.99]) and tobacco status (HR=0.92 [0.85 ; 0.99]). Conclusions: Two-thirds of patients with SC had early progression during 1st-line CT. Platinum-based regimen increased response rate for a few and was an independent factor for better OS with a 8% decreased risk of death. Overall, SC appear to be chemoresistant suggesting that new therapeutic strategies based on a better knowledge of its carcinogenesis should be tested for these patients.

3051 Background: Cancer Associated Macrophage-Like cells (CAMLs) are a recently described circulating stromal cell common in the peripheral blood of patients with solid tumors. In non-small cell lung carcinoma (NSCLC), patients with CAMLs ≥50µm after completion of chemoradiation therapy (CRT) have been shown to have worse progression free survival (PFS). However, with the recent addition of anti-PD-L1 therapies in conjunction with CRT as standard of care, it has never yet to be evaluated whether CAMLs remain predictive for monitoring progression in NSCLC patients post anti-PD-L1 therapy. Methods: A 2 year single blind prospective study was undertaken to test the relationship of ≥50µm CAMLs to PFS based on imaging in lung patients before and after induction of CRT and PD-L1. We recruited 104 patients with pathologically confirmed unresectable NSCLC Stage II (n = 14), Stage III (n = 83), Stage IV (n = 3), and locally recurrent disease (n = 4). Baseline (BL) blood samples were taken prior to start of therapy. A second time point blood sample (T1) was taken at the end of radiotherapy (~40 days). A third time blood sample (T2) was taken after induction of anti-PD-L1 therapy (e.g. Imfinizi, Keytruda, etc.). Blood was filtered by CellSieve filtration and CAMLs were quantified. Analysis by CAML size of < 49 µm or ≥50 µm was used to evaluate PFS hazard ratios (HRs) by censored univariate & multivariate analysis. Results: CAMLs were found in 87% of samples averaging 2.9 CAMLs/7.5mL sample. At BL, CAMLs ≥50 µm had similar PFS to patients with < 50 µm CAMLs (HR = 1.1 95%CI 0.6-1.95 p = 0.8661). However, after CRT (T1), patients with CAML size ≥50 µm had worse PFS (HR = 3.2, 95%CI 1.8-5.8 p = 0.0002). After induction of anti-PD-L1 therapy (T2), patients with ≥50 µm CAMLs also had worse PFS (HR = 2.8 95%CI 1.5-5.4 p = 0.0037). CAML size at BL was not accurate at predicting progression within 24 months; however ≥50 µm CAMLs after CRT or after 1 cycle of anti-PDL1 therapy was 71% accurate at predicting progression of disease. Conclusions: Our data suggests that in NSCLC, ≥50 µm CAMLs after completion of CRT or appearing after induction of anti-PD-L1 therapy appears to predict progressive disease. If validated, additional studies are needed to determine if CAMLs can serve as a significantly prognostic blood based marker for predicting survival in NSCLC patients early in the treatment regime.

The efficacy of first-and second-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in NSCLC patients with the EGFR L861Q mutation has been studied previously. However, there is little evidence on the efficacy of osimertinib in NSCLC patients with uncommon mutations. Here, we report the case of a 68-year-old man with advanced NSCLC with concurrent EGFR L861Q mutation as well as TP53 and RB1 mutations. The patient was treated with osimertinib as first-line therapy and achieved a remarkable progression-free survival of 15 months. His symptoms were significantly alleviated and the dose was well tolerated. The findings of the present study indicate that osimertinib might be a good treatment option for NSCLC patients with the L861Q mutation.
