5042 Background: Sunitinib demonstrated superior progression-free survival (PFS; the primary endpoint) over interferon-alfa (IFN-α) as first-line mRCC therapy (NEJM 2007;356:115). Median overall survival (OS) with sunitinib compared to IFN-α was: 26.4 vs. 21.8 months (HR=0.821; P=0.051 by unstratified log-rank test; Proc ASCO 2008;26, May 20 suppl; abstr 5024). An analysis of prognostic factors for OS was performed on data from this trial. Methods: 750 treatment-naïve mRCC patients were randomized 1:1 to receive sunitinib or IFN-α. By Cox proportional hazards model, selected pretreatment variables were evaluated univariately and in a multivariate model for each treatment arm. Multivariate models for each treatment arm were based on a stepwise algorithm with a type I error of 0.25 for entry and 0.15 for elimination. Further elimination was applied to identify variables significant at P<0.05. Results: In multivariate analysis of sunitinib patients, factors associated with longer OS include: interval from diagnosis to treatment ≥1 yr, ECOG PS of 0, lower corrected calcium, absence of bone metastases, lower lactic dehydrogenase (LDH), and higher hemoglobin (Hgb) ( table ). For the IFN-α treatment arm, male gender, absence of bone or lymph node metastases, lower LDH, higher Hgb, lower corrected calcium, higher neutrophil count, and interval from diagnosis to treatment ≥1 yr were associated with longer OS. Conclusions: For patients in the sunitinib treatment arm, prognostic factors identified were similar to the factors previously identified in the MSKCC risk groups (J Clin Oncol 2002;20:289). Additional prognostic factors were identified for the IFN-α arm. Further studies are warranted to independently validate these findings as well as to identify tumor-specific prognostic factors.

Morphologic Response

743 Background: It was reported that an optimal morphologic response to preoperative chemotherapy was associated with better overall survival (OS) in patients (pts) with colorectal liver metastases (CLM). We investigated association of morphologic response with progression free survival (PFS) in pts with unresectable CLM from HGCSG0802 observational cohort study in pts with mCRC treated with first-line bevacizumab (BV)-based chemotherapy. Methods: The objective of HGCSG0802 was to evaluate PFS, OS, time to treatment failure (TTF), response rate (RR), safety, etc. The key eligibility criteria were evaluable lesions, older than 20 years old, ECOG PS 0-2. Pts with CLM underwent contrast-enhanced CT at the start and every 8-weeks of BV-based chemotherapy. In this analysis, three blinded, independent radiologists evaluated images for morphologic response, based on metastases changing from heterogeneous masses with ill-defined margins into homogeneous hypoattenuating lesions with sharp borders. Association of morphologic response and pts characteristics, RR, and PFS were evaluated. PFS was analyzed with Kaplan-Meier method, log-rank test, and Cox proportional hazards model. Results: Of 108 pts (the full analysis set), 73 pts with CLM were evaluable for morphologic criteria. Eighteen pts (24.7%) had optimal morphologic response (OR), 31 (42.5%) had incomplete (IR), and 24 (32.9%) had no response (NR). The pts characteristics between those with OR, IR and NR were generally balanced. The median TTF was 7.2 months in NR versus 7.2 months in IR versus 6.8 months in OR (HR (OR/NR) = 0.91, HR (OR/IR) = 0.90; p = 0.93). RR was 77.8% in OR versus 64.5% in IR and 58.3% in NR (p = 0.528). The median PFS was 8.3 months in NR versus 8.5 months in IR versus 9.1 months in OR (HR (OR/NR) = 0.72, HR (OR/IR) = 1.04; p = 0.420). Conclusions: In this analysis, morphologic response might not be a prognostic marker in first-line BV-based chemotherapy in pts with CLM.

e16001 Background: The FRESCO phase 3 trial demonstrated a significant survival benefit with fruquintinib vs. placebo in the third-line or later therapy of mCRC patients. CEA levels are widely used in conjunction with imaging to monitor response to systemic therapy in patients with mCRC. Herein, we undertook post-hoc analyses of FRESCO patient data to investigate the early changes in CEA during treatment, as well as potential relationships with efficacy parameters. Methods: Patients were included if baseline CEA was abnormal according to local lab reference range. Serum CEA levels were measured at baseline and Day 1 of each cycle (except for Cycle 1). Early CEA change was analyzed at first radiological evaluation (C3D1, Week 8), CEA response was defined as ≥ 50% decrease from baseline, and CEA progression was defined as ≥ 100% increase from baseline. Overall survival (OS) and progression-free survival (PFS) were evaluated by Kaplan-Meier method; hazard ratio (HR) was estimated through Cox proportional hazards model; p-value was generated from log rank test. Results: 88.4% (245/277) and 94.9% (130/137) of patients had an abnormal baseline CEA in the fruquintinib group and placebo group, respectively. Median baseline CEA values were similar between treatment groups. After 2 cycles of treatment, the proportion of patients had CEA response was significantly higher in the fruquintinib group than placebo group (30.0% vs. 1.3%, p < 0.001). In the fruquintinib group, patients with early CEA response (n = 63) had longer median OS (12.8 vs. 7.8 months, HR = 0.45, p < 0.001) and median PFS (5.6 vs. 3.7 months, HR = 0.49, p < 0.001) than patients without (n = 147). 66.7% (140/210) of patients in fruquintinib group had stable disease (SD), and fruquintinib in those patients with concomitant CEA response exhibited a significantly greater OS benefit than with CEA progression (14.4 vs. 8.7 months, HR = 0.38, p = 0.004). Conclusions: Fruquintinib increased early CEA response. CEA response at first radiological evaluation after cycle 2 could be considered as a predictor for better OS and PFS. Among patients with SD at first evaluation, those with CEA response seems benefit more from fruquintinib. Clinical trial information: NCT02314819 .

e15213 Background: Until recently, few post-D treatment options existed for mCRPC patients (pts). In pts taken off of first-line D for reasons other than progressive disease (PD), retreatment with D at the time of PD was a commonly used strategy. While several prognostic nomograms have been developed for mCRPC patients, none have exclusively examined prognostic factors in D retreated patients. In the present study, we aimed to characterize baseline clinical factors associated with OS outcomes in D retreated mCRPC pts. Methods: Between 1/2007 and 10/2010, all mCRPC pts seen in the Indiana University Simon Cancer Center oncology clinics were approached for recruitment to the IRB approved biorepository protocol. Participants completed a demographic and clinical questionnaire and provided a blood sample. Only mCRPC pts retreated with D with confirmed dates for D first-line completion, D retreatment, and OS were included in this analysis. At D retreatment, patient age, Gleason Grade (GG), presence of pain, time to progression after first-line D therapy, visceral metastases, ECOG performance status, PSA, and PSA doubling time (PSAdt) were examined by Cox proportional hazards model for significant associations (p < 0.05) with OS outcomes. Results: 30 mCRPC pts retreated with D were identified. Complete data were available on 22 pts which formed the analysis cohort. Demographics included: mean age – 69.1 yrs, Caucasian/African-American – 21/1, median GG 8, 55% pain present at baseline, median time from first-line D – 8.6 mo., 30% visceral mets, ECOG 0/1/2 – 3/17/2, mean baseline PSA – 536 ng/ml, mean baseline PSAdt – 2.7 mo. By Cox proportional hazards model, baseline PSA (p = 0.006) was significantly associated with D-retreatment OS with a trend toward significance in patients with pain at baseline (p = 0.059). No other significant associations were identified. Conclusions: Baseline PSA levels were significantly associated with OS outcomes in mCRPC pts retreated with D. Validation and examination of additional clinical variables is warranted in larger datasets.

781 Background: The GERCOR index (GI) based on performance status and serum LDH was reported to be useful to predict survival for patients with previously untreated mCRC. However, in the salvage setting, the validity of the GI has not been reported in patients treated with cetuximab (Cmab)-based chemotherapy. Methods: 269 patients with mCRC treated with Cmab contained chemotherapy were retrospectively registered from 27 centers in Japan. This analysis was included in the KRAS Exon2 wild type patients who were refractory to or intolerant of 5-FU / irinotecan/ oxaliplatin and were never administered anti-EGFR-antibody. Univariate and multivariate analysis for overall survival (OS) were performed using patient characteristics. Survival analyses were performed with the Kaplan-Meier method, log-rank test and the Cox proportional hazards model. The analysis was also designed to determine whether the GERCOR index could be extended to progression-free survival (PFS). Results: All data were available for prognostic categorization in 132 patients. Median OS and PFS were 9.8 and 4.3 months. The distribution and median OS / PFS for GI were as follows: low risk (L)(n = 28; 17.9/3.8 months), intermediate risk (I)(n = 52; 12.2/5.0 months), and high risk (H)(n = 52; 7.5/4.1 months). For OS, there was significant difference between L and H (p < 0.001) and between I and H (p < 0.001), but not between L and I (p = 0.076). For PFS, there was significant difference between I and H (p = 0.017), but not between L and I (p = 0.407), and between L and H (p = 0.222). In the Cox multivariate analysis, GI showed an independent prognostic impact (L vs. I ; HR 2.195, p=0.003 / L vs. H ; HR 4.028, p<0.001), but not predictive impact (L vs. I ; HR 0.987, p=0.958 / L vs. H ; HR 1.314, p=0.268). Conclusions: In this analysis, GI might be a prognostic factor in salvage treatment with Cmab-based chemotherapy.

The objective of this study was to evaluate whether lower uterine segment involvement (LUSI) correlates with recurrence and survival in women with stage I endometrial adenocarcinoma and whether it is associated with poor prognostic histopathologic features. Three hundred seventy-five consecutive patients with endometrial carcinoma stage I compromised the study population. The patients were divided into two groups according to the presence of LUSI with endometrial carcinoma. The two groups were compared with regard to prognostic factors and outcome measures by using the Pearson χ2 test, log-rank test, and Cox proportional hazards model. LUSI was present in 89 (24%) patients with stage I endometrial carcinoma. LUSI was significantly associated with grade 3 tumor (P= 0.022), deep myometrial invasion (P< 0.0001), and the presence of capillary space-like involvement (CSLI) (P= 0.003). Kaplan–Meier survival curves demonstrated that patients with LUSI had a lower recurrence-free survival (log-rank test; P= 0.009) and a worse overall survival (log-rank test; P= 0.0008). In the Cox proportional hazards model, only a trend toward higher recurrence rate (HR = 2.4, 95% CI 0.7, 8.2; P= 0.16) and a trend toward poorer overall survival (HR = 1.54, 95% CI 0.82, 2.91; P= 0.18) were noted when LUSI was present. In patients with stage I endometrial cancer, the presence of LUSI is associated with grade 3 tumor, deep myometrial invasion, and the presence of CSLI. A larger group of patients is necessary to conclude whether higher recurrence rate and poorer overall survival are associated with the presence of LUSI.

1072 Background: In the randomized phase II ATX trial, pts with HER2-negative LR/MBC were treated with first-line AT or ATX. We determined the prognostic value for outcome of VEGF-A, ANG2 and sTIE2 measured at baseline on cycle 1 day 1 (C1D1) and after cycle 1 (C2D1). Methods: 312 pts were randomized in 1:1 ratio to AT (T 90 mg/m2 on d1, 8, 15 and A 10 mg/kg on d1, 15 q4w x 6 cycles, followed by A 15 mg/kg on d1 q3w for next cycles) or ATX (T 90 mg/m2 on d1, 8, A 15 mg/kg on d1 and X 825 mg/m2bid on d1–14 q3w x 8 cycles, followed by the same dose of A and X q3w for next cycles). The primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate (ORR), response duration (RD), overall survival (OS) and safety. Plasma proteins on C1D1 (N = 173) and on C2D1 (N = 142) were measured by ELISA. The association of protein levels (continuous variable) with PFS and OS was evaluated by Cox proportional hazards model and Martingale residual plot. Results: At a median follow-up of 39 months (mo), there were 292 PFS events and 242 deaths. ATX significantly improved PFS as compared to AT (median 11 vs. 8.4 mo, stratified HR = 0.52; 95% CI, 0.41 – 0.67; P < .001). The confirmed ORR in measurable disease (N = 268) was 67% in ATX vs. 50% in AT. Median RD was 6.4 mo (95% CI, 6.1 – 8.3) in ATX v 5.4 mo (95% CI, 5.1 – 6.0) in AT. Median OS was 24.1 mo in ATX vs. 23.1 mo in AT (P= .44). The aselected ‘biomarker’ cohort (N = 173) and overall trial cohort had similar baseline characteristics. ANG2 on C1D1 moderately correlated with sTIE2 on C1D1 (Pearson’s r = .44, P < .001). High ANG2 on C1D1 was significantly associated with poor OS (HR = 1.6; 95% CI, 1.1 – 2.3; P = .01), but not with poor PFS (HR = 1.3; 95% CI, 1.0 – 1.3; P = .07). ANG2 on C2D1 was not significantly associated with OS (HR = 1.55; 95% CI, 0.99 – 2.4; P = .057) or with PFS (P= .6). sTIE2 and VEGF-A were not associated with outcome. All pts had very low levels of free VEGF-A on C2D1 (median 8 pg/ml). Conclusions: In HER2-negative LR/MBC, ATX is more effective (PFS, ORR and RD) than AT. A very high plasma level of ANG2 at baseline indicates a high risk for poor survival. Clinical trial information: NTR1348.

94 Background: The response to Immunotherapy (IO) is known to be affected by concomitant medications including corticosteroids and antibiotics. We evaluated the medication history of patients undergoing IO to explore other medications that affect overall survival and to estimate the relative impact of each medication when given in combination. Methods: A retrospective review of patients with advanced cancer who received IO from 2011 to 2017 at the Ohio State University was performed with IRB approval. Data were extracted from the medical record, including medication history 180 days around the start of IO therapy. Data were collected in a REDCap database. Overall Survival (OS) was calculated from the initiation of IO. Cox Proportional-Hazards models were used and evaluated by log-rank test at alpha = 0.05. All calculations were performed using the survival and survminer packages in R. Results: Patients who received antibiotics or corticosteroids had decreased OS (p = 0.019 and p = 0.043, respectively) across several cancer types. Medications that were not significantly associated with OS included statins (p = 0.38), proton pump inhibitors (p = 0.94), H2 blockers (p = 0.27) and NSAIDS (p = 0.46). A total of 159 patients had complete data for all medications suitable for modeling relative effects. 149 (94%) of patients received antibiotics within 180 days of IO and 19 (12%) received both corticosteroids and antibiotics. The combination of corticosteroids and antibiotics had lower median OS than antibiotics alone or neither medication (p < 0.0018). A Cox Proportional Hazards model of antibiotics and corticosteroids, controlling for age, BMI and ECOG performance status, showed antibiotics, age and BMI to be significant predictors. Conclusions: Antibiotics and corticosteroids near the start of IO reduced overall survival, and the combination reduced the median overall survival further. However, a combined model that controlled for age, BMI and ECOG showed antibiotics, age and BMI to have a significant effect on OS. Though preliminary, these results suggest that antibiotics and corticosteroids may be affecting OS in the context of IO through overlapping pathways.

2075 Background: Although antiangiogenic therapies can induce a dramatic clinical and imaging response in patients with recurrent glioblastoma, their benefit on overall survival is less pronounced. We assessed whether tumor volume based on magnetic resonance imaging (MRI) before and after treatment with bevacizumab can stratify patients in terms of progression-free survival (PFS) and overall survival (OS). Methods: Baseline and post-treatment MRI scans of 93 patients with recurrent glioblastoma treated with bevacizumab were evaluated for volume of the enhancing tumor, as well as volume of the T2/FLAIR hyperintensity. The Cox proportional hazards model was used in univariate and multivariate settings to identify volume parameters prognostic and predictive for PFS and OS. Results: Our results show that baseline enhancing tumor volume were predictive of PFS (p = 0.047) and OS (p = 0.011). Specifically, patients with pretreatment enhancing tumor volume less than 18 cm3 have a median OS of 45 weeks, while patients with tumor volume greater than 18 cm3 have a median OS of 26 weeks. In addition, enhancing tumor volume 3 to 6 weeks after treatment, as well as percentage change in volume, are independent predictors of PFS and OS. Neither T2/FLAIR volume nor percentage change in T2/FLAIR volume was associated with survival. Conclusions: These results indicate that measurement of enhancing tumor volume can help identify patients more likely to benefit from bevacizumab therapy.

The Impact

110 Background: Anecdotal and early evidence suggest ICIs are being used in patients with advanced malignancies and history of AD, despite such patients being typically excluded from traditional clinical trials. We compared the outcomes of patients with or without AD, all of whom had ICI treatment for aNSCLC. Methods: We conducted a retrospective, observational cohort study using de-identified, curated data in ASCO’s CancerLinQ. Patients with Stage III or IV NSCLC who received ≥1 dose of an ICI and had ≥2 visits from Jan 2011 to Nov 2018 were included. AD status prior to ICI treatment was identified using ICD-9/ICD-10 codes or AD medications (including steroids). Symphony claims data were linked via tokenization to build cohorts. Time to treatment discontinuation (TTD), time to next treatment (TTNT), real-world progression-free survival (rwPFS) and overall survival (OS) were compared across the two cohorts using the log-rank test. Cox Proportional Hazards Model was used to adjust for covariates. Adverse events (AEs) were compared using Chi-Square and Fisher’s Exact Test. Active AD was defined as evidence of autoimmune disease in the year prior to starting ICIs. Results: Among 2425 patients with aNSCLC treated with ICIs, AD was present in 22% (N=538). Median OS in all patients was 12.4 months (95% CI 11.3-13.5). TTD, TTNT, rwPFS and OS did not differ between the two cohorts (Table). There was no association between AD status and outcomes. There was no increased incidence of AEs in the AD group; however a sub-analysis among patients with active AD showed higher rates of select AEs including endocrine, GI and blood disorders. Conclusions: This analysis demonstrates that patients with evidence of AD prior to receiving ICI have similar outcomes compared to patients with no evidence of AD. Further research is needed to better understand the impact of active AD on the risk of AEs and patient outcomes. [Table: see text]

Abstract Background Glioblastoma (GBM) is a highly malignant brain tumor with poor survival and prognosis. Randomized trials have demonstrated that chemotherapy improves survival in patients with GBM. This study aims to examine the clinical characteristics that are potentially associated with the efficacy of chemotherapy and the risk factors of GBM. Methods A total of 25,698 patients diagnosed with GBM were identified between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER). The clinical and demographic variables between groups were examined by Student’s t-test and Pearson’s chi-square test. GBM-specific survival (GBMSS) and overall survival (OS) were evaluated using the Kaplan-Meier method with the log-rank test. Univariable and multivariable analyses were also performed using the Cox proportional hazards model to identify statistically significant prognostic factors. Results Patients who received chemotherapy had better overall survival (median OS 13 vs. Three months, HR = 1.9224, 95%CI 1.8571–1.9900, p < 0.0001) and better GBMSS (median GBMSS of 12 vs. Three months, HR = 1.9379, 95%CI 1.8632–2.0156, p < 0.0001), compared to patients who did not. Further subgroup analysis revealed that among patients who underwent chemotherapy, those who were younger, with a supratentorial tumor, received surgery, or radiotherapy had both improved OS and GBMSS. Age, race, tumor location, tumor size, and treatments were identified as independent prognostic factors by multivariable analyses for patients with glioblastoma. Conclusion Patients with GBM who were younger (< 65 years), underwent surgery, or radiotherapy can benefit more from chemotherapeutic regimens. Age, race, tumor size, tumor location, surgery, radiotherapy, and chemotherapy were factors associated with the prognosis of patients with GBM.
