e16630 Background: Nivolumab, an anti-PD1 antibody, is FDA approved in patients (pts) with HCC. Anti-PD-1 promotes hyperstimulation of host immunity and is associated with a spectrum of toxicities known as immune-related adverse events (irAEs). In other malignancies, higher rates of irAEs are associated with improved cancer outcomes. This study shows correlation between irAEs and efficacy in pts with HCC treated with nivolumab. Methods: Demographic and toxicity data were collected retrospectively on all pts with HCC treated with nivolumab at a single institution from Jan 2012 – Sept 2019. Response was evaluated using RECISTv1.1. Adverse events were assessed according to CTCAEv5.0. Categorical variables were assessed by Fisher's exact test. Survival was estimated with the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate analyses were performed by the Cox-regression model. Results: 30 pts were treated; irAEs were detected in 16 (53%). There was no difference in baseline characteristics among those who did and did not experience irAEs (Table). The most frequent irAEs were elevated AST/ALT (n = 7; 44%), rash (n = 4; 25%), and hypothyroid (n = 4; 25%). 3 G3 (rash and transaminitis) and 1 G4 AE (pured red cell apalasia) were observed. Among all pts, overall response rate (RR) and disease control rate (DCR) were 13 and 50%, respectively. Median progression free survival (PFS) and overall survival (OS) were 27 and 56 weeks (w), respectively. The RR and DCR were higher among irAEs vs non-irAEs, although this did not reach statistical significance (RR 25 vs 0%; p = 0.05; DCR 62 vs 35%; p = 0.19). Median PFS and OS were longer in those with irAEs vs non-irAE; PFS 33 vs 16 w (HR: 0.26; CI 95%: 0.076-0.89; p = 0.028); (OS 69 vs 21 w HR: 0.18; CI 95%: 0.05-0.58; p = 0.002). On multivariate analysis, viral etiology was associated with prolonged PFS (p = 0.002) and MELD was associated with reduced OS (p = 0.004). Conclusions: Development of irAEs was associated with prolonged PFS and OS in pts with HCC treated with nivolumab. Further study is needed to determine whether type of irAE, onset time, or duration affect cancer outcomes. [Table: see text]

426 Background: In an open-label, phase IV study of sunitinib as 1st-line treatment (Tx) in Chinese pts with mRCC, median progression-free survival (PFS) and overall survival (OS) were 61.7 and 133.4 wk, respectively; objective response rate (ORR) was 31.1% (Ann Oncol 2012;23:851P). We retrospectively investigated correlations between on-Tx hypertension (HTN), neutropenia (N), and thrombocytopenia (T) and efficacy endpoints in pts from this trial. Methods: HTN was defined by either maximum systolic blood pressure ≥140 mm Hg (S-HTN) or maximum diastolic blood pressure ≥90 mm Hg (D-HTN). Using CTCAE assessment, N grade ≥2 and T grade >1 were used as cut-points for the analyses. Median PFS and OS were estimated by Kaplan−Meier method. The log-rank test was used to compare PFS and OS between groups with and without HTN, N grade ≥2, or T grade >1. Fisher’s exact test was used for ORR. Results: 102 pts were included in the HTN analyses, 60% with S-HTN versus 40% without S-HTN. Pts with S-HTN had greater ORR and longer PFS and OS than pts without S-HTN (Table). (Results were similar with D-HTN; see Table.) 103 pts were included in the N and T analyses, 67% with N grade ≥2 versus 33% with N grade <2, and 56% with T grade >1 versus 44% with T grade ≤1. Pts with N grade ≥2 had significantly greater ORR and significantly longer PFS and OS than pts with N grade <2 (Table). Pts with T grade >1 had greater ORR and significantly longer PFS and OS than pts with T grade ≤1 (Table). Conclusions: The developments of N grade ≥2 and T grade >1 during Tx with sunitinib were significantly associated with better outcome. Median PFS was more than twice as long for pts with S-HTN as for those without S-HTN, but the association did not reach statistical significance. [Table: see text]

e21032 Background: Previous studies suggested that MET exon 14 ( METex14) mutation regarding as a distinct subset was sensitive to MET-inhibitors, but poorly response to immunotherapy. Conversly, MET non-exon-14 (non-ex14) mutations including those undetermined functions and affecting the kinase or extracellular domains were found to be associated with the resistance to MET-inhibitors. However, therapeutic strategies for MET-non-ex14 mutant cancer are still largely unknown, and the relationship between MET-non-ex14 mutations and the efficacy of immune checkpoint inhibitors (ICIs) has never been reported. Using two public ICIs-treated cohorts, we aimed to assess the role of MET mutations including both METex14 and MET-non-ex14 mutations in NSCLC patients undergoing ICIs therapy. Methods: A total of 385 ICIs-treated NSCLC patients were enrolled to our study. MET mutations were defined as any nonsynonymous mutations, and we divided them into METex14 and MET-non-ex14 mutation subsets according to the mutated-position on MET. Kruskal-Wallis test was used to analyze the difference of tumor mutational burden (TMB) score, and the Fisher’s exact test was applied to compare the rates of durable clinical benefit (DCB). Log-rank test was used to analyze the differences between Kaplan-Meier survival curves. Results: In the entire cohort, we found that 17 patients (17/385, 4.4%) had MET mutations, most of which were pure METex14 mutations (10/17, 58.8%). The median TMB of patients in the entire NSCLC cohort was 6.89 mut/Mb. MET-non-ex14 mutant patients (7/385, 1.8%) possessed a significantly higher TMB than METex14-mutant (10/385, 2.6%) and MET wild-type (368/385, 95.6%) sub-cohorts, respectively (median TMB, 17.92 mut/Mb versus 4.17 mut/Mb, p = 0.008; 17.92 mut/Mb versus 6.96 mut/Mb, p = 0.01, respectively). DCB was more common in patients harbored MET-non-ex14 mutations than patients with METex14 mutations and MET wild-type (66.7% versus 14.3%, p = 0.103; 66.7% versus 29.9%, p = 0.075, respectively). We found that patients with MET-non-ex14 mutations had a numerically longer progression free survival (PFS) than those with METex14 mutations and MET wild-type (p = 0.169). Moreover, the PFS was significantly longer in MET-non-ex14-mutant subgroup than patients with METex14 mutations (median PFS, 9.1 versus 2.1 months, p = 0.025). Correspondingly, the overall survival (OS) was significantly longer in MET-non-ex14-mutant subgroup than their wild-type counterparts (median OS, not reached versus 11 months, p = 0.039). Additionally, patients with MET-non-ex14 mutations exhibited relatively better OS versus METex14-mutant patients (median OS, not reached versus 18 months, p = 0.175). Conclusions: MET-non-ex14 mutations were associated with higher TMB, improved DCB rate, and could act as a favorable prognostic biomarker in ICIs-treated NSCLC patients.

ObjectiveWe described progression-free survival and overall survival in patients with primary mucinous ovarian cancer receiving adjuvant gynecologic versus gastrointestinal chemotherapy regimens.MethodsWe identified all primary mucinous ovarian cancer patients receiving adjuvant gynecologic or gastrointestinal chemotherapy regimens at a single institution from 1994 to 2016. Gynecologic pathologists using strict pathologic/clinical criteria determined diagnosis. Adjuvant therapy was coded as gynecologic or gastrointestinal based on standard agents and schedules. Clinical/pathologic/treatment characteristics were recorded. Wilcoxon rank-sum test was used for continuous variables, and Fisher’s exact test for categorical variables. Progression-free and overall survival were calculated using the Kaplan-Meier method, applying landmark analysis.ResultsOf 62 patients identified, 21 received adjuvant chemotherapy: 12 gynecologic, 9 gastrointestinal. Median age (in years) at diagnosis: 58 (range 25–68) gynecologic cohort, 38 (range 32–68) gastrointestinal cohort (p=0.13). Median body mass index at first post-operative visit: 25 kg/m2(range 18–31) gynecologic cohort, 23 kg/m2(range 18–31) gastrointestinal cohort (p=0.23). History of smoking: 6/12 (50%) gynecologic cohort, 3/9 (33%) gastrointestinal cohort (p=0.66). Stage distribution in gynecologic and gastrointestinal cohorts, respectively: stage I: 9/12 (75%) and 3/9 (33%); stage II: 2/12 (17%) and 1/9 (11%); stage III: 1/12 (8%) and 5/9 (56%) (p=0.06). Grade distribution in gynecologic and gastrointestinal cohorts, respectively: grade 1: 8/12 (67%) and 1/9 (13%); grade 2/3: 4/12 (33%) and 7/9 (88%) (p=0.03). Three-year progression-free survival: 90.9% (95% CI 50.8% to 98.7 %) gynecologic, 53.3% (95% CI 17.7% to 79.6%) gastrointestinal. Three-year overall survival: 90.9% (95% CI 50.8% to 98.7%) gynecologic, 76.2% (95% CI 33.2% to 93.5%) gastrointestinal.ConclusionOngoing international collaborative research may further define associations between chemotherapy regimens and survival.

631 Background: Sunitinib remains an important treatment option for mRCC, but the effect of comorbidities/comedications on sunitinib treatment outcomes have not been fully explored. Methods: Data were collated from STAR-TOR, an ongoing real-world registry. Cutoff date for analysis was 19 June 2019. This subgroup analysis assessed the presence or absence of hypertension (HTN), and the use or non-use of statins and proton pump inhibitors (PPIs), determined at the time of entry to the registry. Treatment endpoints were overall survival (OS), progression-free survival (PFS) and objective response rate (ORR). OS and PFS were analyzed by Kaplan-Meier methods. Differences within subgroups were tested using Log-rank test for OS and PFS, and Fisher’s exact test for ORR. Results: 557 sunitinib-treated pts were analyzed; 366 had HTN and 191 did not, 130 used statins and 427 did not, and 165 used PPIs and 392 did not. Median (m) OS (95% confidence intervals) was similar in pts with and without HTN (25.4 [21.1, 31.5] vs 21.5 [15.2, 28.0] months; p = 0.215). mPFS (8.0 [6.5, 9.9] vs 6.3 [5.4, 8.2] months; p = 0.140) and ORR (31.2% vs 30.9%; p = 1.000) were also similar in pts with and without HTN. mOS was similar in pts who used statins vs those who did not (27.8 [20.2, 35.4] vs 24.0 [19.4, 27.3] months; p = 0.884), while mPFS was significantly longer in pts who used statins (9.4 [6.5, 13.6] vs 6.9 [5.7, 8.2] months; p = 0.044). ORR was 37.8% vs 29.0% in pts who did and did not use statins (p = 0.072). mOS was significantly shorter in pts who used PPIs vs those who did not (20.2 [14.9, 28.3] vs 25.7 [22.7, 33.0] months; p = 0.021). mPFS (5.8 [4.6, 8.2] vs 8.0 [6.5, 9.8] months; p = 0.091) and ORR (26.6% vs 33.0%; p = 0.177) were similar in pts who did and did not use PPIs. Conclusions: In sunitinib-treated pts with mRCC in a real-world registry, mPFS was significantly longer and there was a trend toward better ORR in pts who used statins, whereas mOS was significantly shorter and there was a trend toward shorter mPFS in pts who used PPIs. Common comedications may affect sunitinib treatment outcomes in pts with mRCC.

565 Background: Polymorphisms in fragment C receptor (FcγR) are expected as a predictive biomarker of cetuximab (Cmab). Previous studies have convincingly confirmed the distributions (dists) of FcγR polymorphisms in Western population and shown the existence of linkage disequilibrium (LD) between FcγRIIa and FcγRIIIa polymorphisms. Meanwhile, the dists in Asian population have been unknown but a few studies for non-cancer patients have suggested the difference in dists between Asian and Western populations. We investigated the dists of FcγR polymorphisms and their association with clinical response to Cmab in Japanese mCRC patients. Methods: Ninety-three patients with irinotecan/oxaliplatin/5-FU-refractory mCRC and treated by Cmab plus irinotecan or Cmab monotherapy were retrospectively registered from 8 centers in Japan. FcγR polymorphisms were determined from genomic DNA extracted from peripheral blood samples based on the Multiplex allele-specific PCR method. Comparisons according to FcγR polymorphisms were evaluated using Fisher's exact test for response rate (RR) and log-rank test for progression-free survival curves (PFS). Results: The dists of FcγRIIa HH/HR/RR and FcγRIIIa VV/VF/FF were 68/30/2% and 4/40/56%, respectively (Table). The absence of LD between FcγRIIa and FcγRIIIa polymorphisms was confirmed (GENEPOP, p=0.526; Linkdis, p=0.146). Of 74 patients with KRAS wild-type and treated by Cmab plus irinotecan, no difference according to FcγR polymorphisms was observed in either RR (IIa: HH 37% vs. HR/RR 36%, p=1.00; IIIa: VV/VF 39% vs. FF 35%, p= 0.81) or PFS curves (IIa: HH vs. HR/RR, p=0.84; IIIa: VV/VF vs. FF, p=0.09). Similar results were seen in patients treated by cetuximab monotherapy. Conclusions: This study clarified an ethnic difference in the frequencies of FcγR polymorphisms. Associations between the polymorphisms and clinical response to Cmab did not reach a statistical significance. [Table: see text] No significant financial relationships to disclose.

Abstract This study aimed to identify potential predictive factors for the survival of advanced lung adenocarcinoma patients undergoing pemetrexed maintenance therapy. 122 advanced lung adenocarcinoma patients who received pemetrexed maintenance therapy were retrospectively analyzed. Kaplan–Meier method with Log-rank test was used for survival analysis. Univariate and multivariate Cox regression were performed to evaluate prognostic factors for overall survival (OS) and progression-free survival (PFS). Bivariate correlation analysis was used for exploratory purpose. For the whole cohort of 122 patients, median PFS was 11.97 months (95% CI 10.611–13.329) and estimated median OS was 45.07 months (95% CI 31.690–58.450). The mPFS of ALK-positive patients was superior to negative patients (18.27 vs. 11.90 months; P  = 0.039). Patients with ECOG PS 0 (14.4 vs. 11.1 months; p = 0.040) and patients with single-organ metastasis (19.0 vs. 11.0 months; p = 0.014) had prolonged median PFS. Compared with the low PD-L1 expression group, PFS of high PD-L1 expression group were improved (13.6 vs. 11.1 months, p = 0.104, at 1% cut-off; 17.5 vs. 11.1 months, p = 0.009, at 10% cut-off; and 27.5 vs. 11.4 months, p = 0.005, at 50% cut-off). No differences were found between EGFR positive and negative patients. PD-L1 expression was an independent prognostic factor for both PFS and OS times (PFS: HR, 0.175; P  = 0.001; OS: HR, 0.107; P  = 0.036). Bivariate correlation showed a significant positive correlation between PD-L1 expression and PFS (correlation coefficient R = 0.485, P  < 0.001). High PD-L1 expression could be a potential effective predictor for favorable survival of advanced lung adenocarcinoma patients undergoing pemetrexed maintenance therapy.

e14622 Background: Data from the Czech national registry of patients treated with targeted therapies for mCRC were analyzed retrospectively to compare treatment outcomes for bevacizumab in combination with chemotherapy in the 1st, 2nd and 3rd line of treatment. Methods: The database was launched in 2005 as a clinical registry of patients with mCRC treated with bevacizumab. Epidemiological and clinical data are entered by all Czech comprehensive cancer centers administering targeted therapy. In total, 4487 mCRC patients who received bevacizumab combined with chemotherapy in either 1st line (n=3990, 88.9%), 2nd line (n=386, 8.6%), or 3rd and higher line (n=111, 2.5%) had evaluable data and were included in the present analysis. Survival was calculated using the Kaplan-Meier method, and the differences were assessed using the log-rank test. Results: Statistically significant differences were observed in the efficacy of combination chemotherapy with bevacizumab between the treatment lines. The objective response rate (ORR) in the 1st, 2nd, and 3rd/higher line was 42.9%, 34.0% and 8.3%; (p<0.001) respectively. Similarly, in the 1st, 2nd, and 3rd/higher line median progression free survival (mPFS) was 11.3 months (95% CI 11.0-11.7 months), 9.5 months (95% CI 8.2-10.9 months) , and 7.3 months (95% CI 5.9-8.7 months; p<0.001), and median overall survival (mOS) was 28.4 months (95% CI 27.1-29.8 months), 25.9 months (95% CI 19.4-32.4 months), and 15.0 months (95% CI 10.7-19.3 months; p<0.001), respectively. The spectrum of the most common adverse events was comparable in the 1st, 2nd, or 3rd/higher line, and incidence of adverse events was similar at 11.6%, 8.8% and 8.1%, respectively. Conclusions: The efficacy of bevacizumab in combination with chemotherapy decreased when administered in later lines of treatment for mCRC while the incidence and spectrum of toxicities remains unchanged.

e21076 Background: PD-L1 inhibitor, durvalumab has been approved since the PACIFIC study showed its efficacy as consolidation therapy after CCRT for locally advanced NSCLC. But predictive factor for the efficacy of CCRT on this post PACIFIC era have not been known. LIPI has been proposed as a new biomarker for the anti-PD-1 therapy of advanced NSCLC. In this study, we investigated the usefulness of LIPI as a predictive marker in multicenter cohort of patients with locally advanced NSCLC who received CCRT as initial treatment. Methods: 219 patients with available baseline LIPI were reviewed. The progression free survival (PFS) was estimated by the Kaplan-Meier method, and LIPI were calculated at baseline. Kaplan-Meier estimates of PFS and recurrence were compared using the log-rank test for trend. Multivariable analysis was conducted using the Cox and logistic regression models, respectively, adjusted for age, sex, ECOG-PS, smoking, histology, TNM stage, chemotherapy regimens, Body mass index (BMI), PD-L1 status, EGFR or ALK mutation, and baseline LIPI. Results: 62.5% (n = 137) of the patients had a good (0 factors) LIPI, while 37.5% (n = 82) had intermediate (1 factor) and poor (2 factors) LIPI respectively. In multivariable analysis, good LIPI (0 factors) were significantly associated with longer PFS (HR = 0.46, 95% CI 0.28-0.75; P < 0.01) as did ECOG-PS0 (P < 0.01), ≤stageIIIA (P < 0.01), being treated with durvalumab after CRT (P = 0.04). There were no difference in the patient characteristics between good LIPI and intermediate/poor LIPI, significantly. Higher LIPI (1 or 2 factors) were strongly prognostic factor for recurrence after CCRT in multivariate analysis (P = 0.04), along with ECOG-PS1≤ (P < 0.01), stage IIIB≤ (P < 0.01). Conclusions: The good LIPI predictive value for PFS and disease control in patients treated with CCRT was confirmed. Although a strong statistical significance, we needs to be confirmed further with longer follow-up and prospective study.

Abstract Introduction: Waldenström macroglobulinaemia/ Lymphoplasmacytoid lymphoma (WM/LPL) is a rare lymphoproliferative neoplasm characterized by small B lymphocytes proliferation. Abnormalities of thyroid hormones are common in clinical courses. Yet, the role of thyroid complications has not been explored in WM/LPL. Hence, the aim of this study was to investigate the clinical significance of thyroid complications in WM/LPL. Methods: 105 clinically diagnostic WM/LPL patients from Shandong Provincial Hospital were enrolled with informed consents. Baseline and clinical data concerning sex, age, International Staging System Waldenstrom Macroglobulinemia (ISSWM) score et al were collected. Chi-square test was used for comparison of clinical characteristics. The Kaplan-Meier method was used for analysis of survival outcomes. Cox regression analyses were utilized to identify prognostic-related key factors associated with overall survival (OS) and progression-free survival (PFS) in WM/LPL patients. Microarray datasets GSE6691 were obtained from Gene Expression Omnibus. Results: Over the 105 WM/LPL patients, the median overall survival (OS) was not reached and median progression-free survival (PFS) was 96 months (Figure 1A, 1B). Patients classified as complete response (CR)/ partial response (PR)/ stable disease (SD), showed better OS and PFS than patients with progression disease (PD) (Figure 1C, D). There were 13.3% of enrolled patients with mixed thyroid complications. The results of Chi-square test showed that thyroid complications were significantly associated with reduced IgM level (p=0.036) and elevated β2-macroglobulin (p=0.032). Moreover, patients without thyroid comorbidities were more likely to get overall response (CR+PR) to the first-line treatment (p=0.004). Kaplan-Meier curves showed patients with thyroid complications had significantly shorter OS (p=0.02) and PFS (p&lt;0.001) versus those without thyroid complications (Figure 1E, F). In the univariate Cox regression model, age (p=0.022), ISSWM score (p=0.014) and thyroid complications (p&lt;0.001) were significantly associated with an increased risk of progression developed. Subsequent multivariate analysis showed the presence of thyroid complications was an independent prognostic indicator for PFS in WM/LPL patients (p=0.03). However, there was no statistical significance of thyroid complications in OS. Microarray dataset analysis was conducted to further investigate the role of thyroid-related genes in WM/LPL patients. A network of interactions among thyroid-related genes and critical factors in WM/LPL, including MYD88 and CXCR4, was shown in Figure 1G. Correlations were statistically significant between SLC5A5 (p&lt;0.05), TG (p&lt;0.01), TPO (p&lt;0.01) and CXCR4 by Spearman correlation analysis (Figure 1H, I). In addition, differential gene expression analysis between the WM and normal lymphocytes was assessed (Figure 1J). Thyroid-related genes with statistical significance were annotated in the volcano plots (Figure 1K). Enrichment analysis indicated that differential genes were involving in PI3K-Akt signaling pathway and response to peptide hormone (Figure 1L). Moreover, five of them reached statistical significance, illuminating the potential importance of thyroid-related genes in WM/LPL (Figure 1M). Conclusion: Taken together, the present study was the first investigation on the role of thyroid complications in WM/LPL. Patients with thyroid complications showed worse clinical characteristics and conferred independent prognostic significance. The primary strength of this study is that it provides robust real-world evidence on the prognostic role of thyroid complications, highlighting the need to monitor and appropriately manage WM/LPL patients with thyroid complications in medical admissions.

ObjectivesOur aim was to investigate the pulmonary function test (PFT) results of patients with asbestosis and determine whether baseline PFTs and the risk-predicting models such as gender, age and physiologic (GAP) variables model and composite physiologic index (CPI) would be useful in predicting survival in these patients.MethodsDemographics and PFTs of 100 patients with asbestosis were evaluated. The survival difference between the GAP stages was determined with Kaplan-Meier survival curves with statistical significance analysed with log-rank test. The suitability of the risk-predicting models and baseline PFTs to predict the survival of patients was analysed with Cox regression.ResultsAt baseline, the mean value of diffusion capacity for carbon monoxide (DLCO) was 65%; for forced vital capacity it was 81%, with restrictive lung function being the most common impairment. The median estimated survival of the patients was 124 months, that is, 171 months in GAP stage I, 50 months in stage II and 21 months in stage III (p<0.001). CPI, DLCO% predicted, age at baseline and GAP stage were significant predictors of mortality (all p values under 0.001).ConclusionsGAP and CPI as well as baseline DLCO% predicted were significant parameters in the evaluation of the prognosis of the patients with asbestosis; they may be useful in clinical practice when considering treatment strategies of individual patients.
