4014 Background: In this large phase III trial, median progression-free survival (PFS) improved by 5.1 mo with E+O compared to P+O in patients (pts) with NET associated with carcinoid syndrome. Baseline imbalances including WHO performance status (PS) and primary site favoring P+O confounded primary analysis. Chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5-HIAA) are important biomarkers in NET. Analyses were performed to identify prognostic factors and adjust for baseline imbalances. Methods: Pts were randomized to E+O (n=216) or P+O (n=213). Potential prognostic factors including baseline CgA (≤2×ULN vs >2×ULN), baseline 5-HIAA (≤median vs >median at baseline), age (<65 vs ≥65), gender, race, WHO PS (0 vs 1, 2), primary site (lung vs other), prior somatostatin analog use (yes vs no), duration from diagnosis (<6 mo, 6-24 mo, 2-5 yr, >5 yr), and organs involved (liver, bone) were assessed in univariate analysis using the log rank test and stepwise regression using Cox proportional hazards model. Results: Median PFS (mo) was significantly longer for pts with nonelevated CgA (27 vs 11; p<.001) and nonelevated 5-HIAA (17 vs 11; p<.001). Analyses also indicated age (14 vs 12; p=.01), WHO PS (17 vs 11; p=.004), liver involvement (14 vs not reached; p=.02), bone metastases (8 vs 15; p<.001), and lung as primary site (11 vs 14; p=.06) as potentially prognostic. Multivariate analysis indicated that significant prognostic factors for PFS included baseline CgA (HR, 0.47; CI, 0.34-0.65; p<.001), WHO PS (HR, 0.69; CI, 0.52-0.90; p=.006), bone involvement (HR, 1.52; CI, 1.06-2.18; p=.02), and lung as primary site (HR, 1.55; CI, 1.01-2.36; p=.04). Adjusted for covariates, a 38% reduction in risk of progression was observed for E+O (HR, 0.62; 95% CI, 0.51-0.87; p=.003). Conclusions: In the phase III RADIANT-2 trial, baseline CgA levels, WHO PS, lung as primary site, and bone involvement were important prognostic factors. Exploratory analysis adjusted for these prognostic factors indicated significant benefit of everolimus therapy.

157 Background: In this large phase III trial, median progression-free survival (PFS) improved by 5.1 mo with E+O compared to P+O in patients (pts) with NET associated with carcinoid syndrome. Randomization imbalances including WHO performance status (PS), and primary site favoring P+O confounded primary analysis. Chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5-HIAA) are important biomarkers in NET. Analyses were performed to identify prognostic factors and adjust for randomization imbalances. Methods: Pts were randomized to E+O (n=216) or P+O (n=213). Potential prognostic factors including baseline CgA (≤2×ULN vs >2×ULN), baseline 5-HIAA (≤median vs >median), age (<65 vs ≥65), gender, race, WHO PS (0 vs 1, 2), primary site (lung vs other), prior somatostatin analog use (yes vs no), duration from diagnosis (<6 mo, 6-24 mo, 2-5 yr, >5 yr), and organs involved (liver, bone) were assessed in univariate analysis using the log rank test and a stepwise regression using Cox proportional hazards model. Results: Randomization resulted in significant imbalance in baseline CgA (median [ng/mL], 251 E+O vs 137 P+O). Median PFS (mo) was significantly longer for pts with nonelevated CgA (27 vs 11; P<.001) and nonelevated 5-HIAA (17 vs 11; P<.001). Analyses also indicated age (14 vs 12; P=.01), WHO PS (17 vs 11; P=.004), liver involvement (14 vs not reached; P=.02), bone metastases (8 vs 15; P<.001), and lung as primary site (11 vs 14; P=.06) as potentially prognostic. Multivariate analysis indicated that significant prognostic factors for PFS included baseline CgA (HR, 0.47; CI, 0.34-0.65; P<.001), WHO PS (HR, 0.69; CI, 0.52-0.90; P=.006), bone involvement (HR, 1.52; CI, 1.06-2.18; P=.02), and lung as primary site (HR, 1.55; CI, 1.01-2.36; P=.04). Adjusted for covariates, a 38% reduction in risk of progression was observed for E+O (HR, 0.62; 95% CI, 0.51-0.87; P=.003). Conclusions: In the phase III RADIANT-2 trial, baseline CgA levels, WHO PS, lung as primary site, and bone involvement were important prognostic factors. Exploratory analysis adjusted for these prognostic factors indicated significant benefit for everolimus therapy.

125 Background: BOLERO-2, a phase III study, randomized 724 patients with hormone-receptor–positive metastatic breast cancer, who had recurrence or progression on/after prior nonsteroidal aromatase inhibitor therapy, to everolimus (EVE) + exemestane (EXE) or EXE + placebo. A preplanned 12-mo median time interim analysis demonstrated that EVE + EXE significantly improved progression-free survival (PFS) vs EXE + placebo, but EVE + EXE resulted in a higher rate of grade 3-4 toxicity. Per-protocol patients reported HRQoL data are limited; here we report on additional post hoc analyses of these outcomes. Methods: Using the EORTC QLQ-C30 questionnaire, HRQoL was assessed at baseline and every 6 weeks thereafter until progression. QLQ-C30 consists of 30 items combined into 15 subscales, including a Global Health Status (GHS), where higher scores (range, 0-100) indicate better HRQoL. Analysis included a protocol-specified time to definitive deterioration (TTD) analysis at a 5% decrease in QoL relative to baseline, with no subsequent increase above this threshold. We report additional sensitivity analyses using 10-point minimally important difference (MID) decreases in QLQ-C30 score relative to baseline. Treatment arms were compared using a stratified log-rank test and a Cox proportional hazards model adjusted for trial stratum (visceral metastases and previous hormone sensitivity), age, sex, race, baseline score, ECOG performance status, prognostic risk factors, and treatment history. Results: Baseline QLQ-C30 GHS scores were not statistically significantly different across treatment groups (64.7 vs 65.3; difference –0.7 [95% CI, –4.3-3.0]). Median TTD in HRQoL was 7.0 mo (95% CI, 5.6-8.3) for EVE + EXE vs 5.6 (95% CI, 4.2-7.0) for EXE (p = .0792). Adjusted HR (0.80) approached significance (95% CI, 0.63-1.02). At the 10-point MID, median TTD for EVE + EXE was 9.7 mo (95% CI, 8.3-11.2) vs 8.4 mo (95% CI, 6.3-12.5) for EXE. Adjusted HR was 0.90 (95% CI, 0.69-1.18). Conclusions: These additional analyses from the BOLERO-2 study demonstrate that in addition to significantly improving PFS, EVE + EXE does not compromise HRQoL.

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.

ObjectiveTo evaluate the frequency and predictors of bone metastasis in patients with ovarian cancer and to determine prognostic factors associated with this finding.MethodsPatients diagnosed with ovarian cancer between January 2009 and December 2019 were evaluated. Patients with radiologically or pathologically confirmed bone metastasis were included in the study. Survival was analyzed using Kaplan-Meier curves and compared using the log-rank test. Multivariate analysis of prognostic factors related to survival was performed using the Cox proportional hazards model.ResultsNineteen (2.6%) of 736 patients had bone metastases. Patients with clear cell histology had a higher risk of bone metastases than patients with the other epithelial histology groups (12.3% vs 2.1%, p<0.001). Overall survival was significantly lower in patients diagnosed with bone metastasis at the time of cancer diagnosis than in those diagnosed with bone metastasis during the course of the disease (median 63 vs 6.1 months, p<0.001). However, when the survival time after the development of bone metastasis was examined, no difference was found between patients with metastasis at the time of diagnosis and at the time of first or later progression (median 13.6 vs 4 months, p=0.09). In addition, the median survival of patients with clear cell histology after bone metastasis did not differ statistically from that of patients with other epithelial histology (median 22 vs 7.5 months; p=0.13). In the clear cell subgroup, bone metastasis was an independent prognostic factor for survival after multivariate analysis. For all patients, the stage at diagnosis and serum CA125 and alkaline phosphatase levels at the time of bone metastasis were prognostic factors for survival.DiscussionBone metastasis is rare in patients with ovarian cancer. However, the risk of bone metastasis is highest in patients with clear cell histology.

412 Background: Current guidelines do not yet provide any recommendations for any serum tumor markers in patients with upper tract urothelial carcinoma (UTUC). Even today radiological images cannot diagnose muscle invasion correctly. Previous studies have shown that serum cytokeratin levels were correlated with depth of tumor invasion and metastases in patients with bladder cancer. In this study we evaluated whether preoperative serum cytokeratin 19 fragment levels (sCK19) could be a prognostic marker for survival in patients who received nephroureterectomy (NU). Methods: 160 cases with UTUC underwent NU from December 2003 to 2014 at our institution. The median age was 73 years. Preoperative sCK19 was measured in 138 cases. The patients were divided into two groups, high sCK19 group (HG) and low group (LG) based on sCK19 (a cut-off value: 3.5 ng/mL). Cancer-specific survival (CSS) and progression-free survival (PFS) were measured by Kaplan–Meier curves and statistical analysis was performed by the log–rank test. Multivariate analysis was carried out using the Cox proportional hazards model. Results: Of 138 cases ≤pT1 was 54 (39%), pT2 in 31 (22%), pT3 in 45 (32%) and pT4 in 8 (5%). 37 cases (23%) were the HG and 101 (78%) were the LG. sCK19 were significantly correlated with pT (rs 0.213, p=0.013, Spearman rank correlation). The median follow-up time was 34.0 months. In all cases the 5-year CSS was 78% and PFS was 60%. The 5-year CSS of the HG (57%) was significantly lower than the LG (86%) (p=0.001). The 5-year PFS of the HG (36%) was significantly lower than that of the LG (67%) (p<0.001). On univariate analysis, pT stage, lymphovascular invasion, positive margin (PM) and sCK19 were the significant factors for CSS. On multivariate analysis, sCK19 (HR4.2, p=0.001) and PM (HR2.9, p=0.001) were the independent poor prognostic factors. Conclusions: Preoperative sCK19 was the prognostic factor for the patients with UTUC. Systemic chemotherapy should be considered before NU in patients with high preoperative sCK19 levels independent of radiological findings.

e17033 Background: Sarcomatoid urothelial carcinoma (SUC) is a rare and aggressive bladder cancer variant with little evidence regarding prognostic characteristics and response to neoadjuvant chemotherapy (NAC). In this study, we delineate oncologic outcomes in patients with SUC after radical cystectomy (RC), presenting data from our institutional database and SEER-Medicare. Methods: We retrospectively queried our institutional database to identify consecutive patients with cT2-4 SUC and conventional (non-variant) UC (CUC) who underwent RC (2003-2018). SEER-Medicare database was also searched for patients with cT2-4 SUC (2004-2015). Clinicopathologic/treatment data were captured. Overall survival (OS – diagnosis to death) was estimated with the Kaplan-Meier method. T-test, χ2 test and log-rank test were used for group comparison analysis. Factors significant in univariate analysis for OS were included in the multivariate (MVA) Cox proportional hazards model. Results: Institutional RC database yielded 38 patients with SUC and 287 with CUC, while 190 patients with SUC were identified from SEER-Medicare [83 (44%) had RC]. Platinum-based NAC was given to 17/38 (45%), 162/287 (56%) and 26/83 (31%) patients, respectively. Institutional patients with SUC had significantly higher rates of pT3/4 disease at RC (66% vs. 35%, p < .001) and lower rates of complete pathologic response (ypT0N0) following NAC (6% vs 35%, p = .02). Median OS in patients who had RC was significantly inferior in our institutional SUC vs. CUC group (20 vs. 121 months, p < .001) and 21 months in the SEER-SUC cohort. No significant difference in OS was identified between NAC+RC vs. RC alone, both in the institutional (17 vs. 20 months, p = 0.66) and SEER-SUC cohort (24 vs. 20 months, p = 0.56). In MVA for the entire institutional cohort (SUC+CUC combined), SUC was independently associated with worse OS, when adjusted for advanced age, pT/N stage, performance status, NAC, lymphovascular invasion, surgical margins (HR, 95% CI: 2.3, 1.4 - 3.8, p = .001). Five patients had an abdomino-pelvic cystic recurrence, with median time to recurrence < 5 months. Conclusions: Patients with SUC treated with RC had high rates of extravesical extension, poor response to platinum-based NAC and worse OS compared to patients with CUC. Data from SEER showed a comparable OS to our SUC cohort. NAC was not associated with improved OS in any SUC cohort (institutional or SEER). A unique pattern of rapid abdomino-pelvic cystic recurrence, mimicking post-RC abdominal fluid collections, was also identified.

e18689 Background: While guidelines exist for appropriate use of chemotherapy in the metastatic setting based on performance status, such recommendations are less readily available for immune checkpoint inhibitors (ICIs). We sought to determine if there is a relationship between Eastern Cooperative Oncology Group (ECOG) performance status and outcomes on immunotherapy in patients treated for metastatic disease at our community-based oncology practice. Methods: 253 patients were identified as receiving nivolumab or pembrolizumab for stage IV malignancy at Cancer Centers of Colorado-SCL Health, between June 2018 and November 2020. Patients initiated on therapy after May 2020 were excluded from analysis, due to insufficient (less than 6 months) follow-up time. The remaining 183 patients were included in a retrospective cohort study comparing patients with ECOG 0, ECOG 1, and ECOG 2-4. Sex, age, type of cancer, and line of therapy were collected. Time on therapy was also calculated. Best response to therapy was determined (disease control or progressive disease). These baseline factors and outcomes were compared using ANOVA for numeric variables and chi-square tests of association for categorical variables. Time from initiation of ICI to death or hospice was also investigated and compared using a log-rank test. In addition, a multivariate Cox proportional hazards model was developed for the outcome, time to death/hospice, versus the predictors ECOG status, age, gender, and line of therapy. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated. Results: Of the 183 patients included in analysis, 31.7% had an ECOG of 0, 48.6% an ECOG of 1, and 19.7% an ECOG of 2-4. Non-small cell lung cancer and melanoma represented the majority of patients in each group. Gender and line of therapy did not differ between groups. There was a significant difference in age (p = 0.02) with mean age 62, 66, and 70 in ECOG 0,1, and 2-4, respectively. 54.6% of patients remained on therapy for at least 6 months (182 days), and there was no significant difference between groups in ability to complete 6 months of therapy (p = 0.32). For ECOG 0, 1, and 2-4, disease control was achieved in 67.2%, 59.6 %, and 41.7%, respectively (p = 0.048). Analysis of time to death/hospice with a log rank test and Kaplan Meier plot showed a significant difference between groups (p < 0.001). A multivariate Cox proportional hazards model revealed that patients with ECOG 0 had significantly longer time to death/hospice compared to patients in both other groups, after controlling for age, gender, and line of therapy (ECOG 1 vs. 0: HR 2.5, CI 1.27-4.9; ECOG 2-4 vs. 0: HR 2.83, CI 1.31-6.13). Conclusions: In this single institution retrospective study of patients receiving nivolumab or pembrolizumab for metastatic cancer, ECOG 0 was associated with disease control and increased time before death or transition to hospice.

PURPOSE: To identify the prognostic factors that influence overall survival (OS) in patients with stage III-IV follicular lymphomas and evaluate the clinical usefulness and the prognostic value of the International Prognostic Index (IPI). PATIENTS AND METHODS: Four hundred eighty-four patients with Ann Arbor stage III-IV follicular lymphomas treated in two phase III trials from 1986 to 1995 were screened for this study. All histologic slides were reviewed by two hematopathologists. The influence of the initial parameters on survival was defined by univariate (log-rank test) and multivariate (Cox model) analyses. RESULTS: The poor prognostic factors for OS (age > 60 years, “B” symptom(s), ≥ two extranodal sites, stage IV disease, tumor bulk > 7 cm, at least three nodal sites > 3 cm, liver involvement, serous effusion-compression or orbital/epidural involvement, and erythrocyte sedimentation rate > 30 mm/h) that were significant in univariate analysis were subjected to multivariate analysis. Three factors remained significant: B symptom(s) (risk ratio = 1.80), age greater than 60 years (risk ratio = 1.60), and at least three nodal sites greater than 3 cm (risk ratio = 1.71). When the IPI was applied to these patients, the score was 1, 2, 3, and 4-5 in 49%, 39%, 11%, and 2%, respectively, and it was significant for progression-free survival (P = .002) and OS (P = .0001). CONCLUSION: Three prognostic factors for poor OS were identified: B symptoms, age greater than 60 years, and at least three nodal sites greater than 3 cm. The IPI was prognostic for OS, but in this population, a very low number of patients belonged to the high-risk groups.

17010 Background: Negative impact of anemia on survival has been described in NSCLC patients (pts) treated with radiotherapy (RT) or concurrent radiochemotherapy, but scarcely data exist in NSCLC treated with chemotherapy (CT). PURPOUSE: To evaluate the prognosis value of baseline hemoglobin (Hb) among pts with advanced NSCLC treated with cisplatin and gemcitabine. Methods: 433 pts included in two trials conducted by the Spanish Lung Cancer Group (176 pts from the arm A of a randomized phase III trial comparing 3 regimens of CT and 257 pts from a phase II trial) were included in this analysis. No significant differences in baseline characteristics, response and survival (median 8.73 and 9.87 months, p=0.46) were observed between pts of the two trials. The baseline Hb and other potential risk factors for survival were analyzed with Cox Proportional Hazards model in an univariate an multivariate analysis. Results: Stage IIIB with positive pleural effusion (25%), stage IV (75%). 85% had ECOG PS 0–1. Median age: 60 years (range 31–82). 89% male. Histology: 41% adenocarcinoma, 39% squamous cell, 6.5% large cell, 14.5% NSCLC not otherwise specified. Median number of cycles received was 4 (range 1–8). Mean Hb level prior CT was 13.2 g/dl (range 8 to 19.6 g/dl). Response rate was 41% and median survival was 9.57 months (95% CI: 8.57–11–57). No statistically differences in survival were observed by stage (IIIB vs IV), age and gender. In the univariate analysis, number of cycles received (≤3 vs. >3 cycles), ECOG (2 vs 0–1), response (SD+PD vs CR+PR), baseline Hb (≤11 vs >11 gr/dl); minimum Hb during the CT (<10 vs ≥10) and second line CT (No vs Yes) emerged as prognostic factors for survival and were introduced in the multivariate model (see Table ). Conclusions: Hb level at the initiation of CT is an independent prognostic factor of survival this homogenous group of advanced NSCLC treated with cisplatin and gemcitabine. Baseline Hb should be considered as prognosis factor for survival in addition to ECOG. [Table: see text] No significant financial relationships to disclose.

Phase I Clinical Trials

2568 Background: For investigators, the selection of patients to be considered for phase I clinical trials is difficult, because of the lack of objective criteria for a rational decision-making process. From October 1997 to October 2002, we retrospectively assessed prognostic factors for cancer patients considered for Phase 1 trials. Methods: 148 consecutive patients who had been screened for inclusion in 6 different phase I trials were included in the present study. 70 out of them actually received the phase I treatment. Univariate (Log-Rank test) and multivariate analysis (Cox proportional hazard ratio model) were performed to determine the prognostic factors related to overall survival (OS) after screening. Results: The study comprised 63 men and 85 women, with a median age of 54 (range 23–79). The most frequent primary cancer sites were: breast (38 cases), head and neck (28 cases), lung (18 cases) and colorectal (17 cases). 91 out of them had a performance status PS = 0. The median OS of the 148 patients was 5.7 months (173 days, range 1–2,421). Univariate analysis identified PS = 1, Body Mass Index < 20, liver and visceral metastasis, serum albumin < 38 g/L, lymphocytes count < 0.7 x 109/L and granulocytes count > 7.5 x 109/L as poor prognostic factors. The Cox model identified serum albumin < 38 g/L (HR 2.51 [1.51–4.18], p=0.0001) and lymphocyte count < 0.7 x 109/L (HR 2.27 [1.13–4.62], p=0.024) as independent prognostic variables for OS. All patients presenting with both prognostic factors died within 90 days. Conclusion: We propose a simple model, easily obtained at the patient bedside, which can discriminate patients who have a life expectancy of over 3 months and thus could be enrolled in phase-I anti-cancer trials.
