677 Background: The Phase III RECOURSE trial, in patients (pts) with metastatic colorectal cancer (mCRC) refractory to standard therapies, demonstrated that trifluridine/tipiracil (FTD/TPI) significantly extended overall survival (OS) and progression-free survival (PFS) versus placebo in all subgroups, regardless of age, geographical origin, or KRAS status, with acceptable safety. Literature reports have shown optimal benefit for pts with low tumor burden (< 3 metastatic sites), indolent disease (≥ 18 mo since diagnosis of first metastasis), ECOG PS 0-1, and no liver metastasis when treated in late line mCRC. Methods: This exploratory post hoc analysis of RECOURSE (all ECOG 0-1) compared pts on FTD/TPI or placebo with good prognostic characteristics (GPC; low tumor burden and indolent disease) and poor prognostic characteristics (PPC; high tumor burden and/or aggressive disease). These subgroups were then analyzed by liver metastasis at baseline, ECOG PS, KRAS status and age. Results: Baseline characteristics were generally similar between the two groups. GPC placebo pts performed better than the PPC placebo pts, but worse than the GPC pts treated with FTD/TPI. GPC pts treated with FTD/TPI showed median OS of 9.3 mo versus 5.3 mo in PPC pts (HR 0.46; 95% CI: 0.37, 0.57; p < 0.0001); there was a similar effect for PFS. GPC pts had significantly better mOS and mPFS regardless of age (≥ 65 vs. < 65 y), ECOG PS (0–1), KRAS status (mutant vs. wildtype), and liver metastasis (y/n). No liver metastasis was the best prognostic factor: mOS in such pts treated with FTD/TPI was 16.4 mo and 7.6 mo in the GPC (n = 97) and PPC (n = 35) groups, respectively (HR 0.42; 95% CI: 0.24, 0.74; p < 0.0019); there was a similar effect for PFS. Pts with ECOG PS 0 at baseline remained PS 0-1 at discontinuation in 96% of the GPC group. Conclusions: Low tumor burden and indolent disease indicate good prognosis in late line mCRC. Pts with no liver metastasis have the best prognosis and are likely to have longer OS. GPCs might explain the percentage of long-term responders on FTD/TPI in RECOURSE. Maintenance of ECOG PS 0–1 during treatment is crucial in the continuum of care, allowing pts to benefit from further treatment options. Clinical trial information: NCT01607957.

146 Background: FTD/TPI has demonstrated significantly overall survival (OS) and progression-free survival (PFS) in patients (pts) with metastatic colorectal cancer (mCRC) refractory to standard therapies. Nevertheless, data regarding the pt profile that benefits most from this FTD/TPI is scarce. Some reports have shown optimal benefit for pts with low tumor burden indolent disease, ECOG PS 0-1, and no liver metastasis. Methods: We conducted a retrospective, multicenter, observational study of pts treated with FTD/TPI at eight hospitals from the Galician Research Group on Digestive Tumours (GITuD). Data were analyzed for a correlation between prognostic characteristics (good prognostic characteristics (GPC) vs. poor prognostic characteristics (PPC)), clinicopathological characteristics and survival. The GPC group was composed of pts who have one or two metastatic sites and time from diagnosis of 1st metastases to treatment ≥ 18 months. Results: Between January 1, 2017 and August 20, 2018, 160 pts were included in the study, of which 85 pts (53.1%) were classified as PPC and 75 pts (46.9%), as GPC. Pts with PPC were associated with younger age (60.5 vs. 63.7 years, p=0.034), higher presence of liver metastases (83.5% vs. 60%, p=0.001) and lower incidence of primary tumor resection (34.1% vs. 17.3%, p=0.019), without differences in ECOG PS, RAS mutation, tumor stage at diagnosis, lung metastases and sidedness. In the whole population of pts median OS and PFS were 7.63 months and 2.75 months, respectively. However, in the GPC and PPC groups mPFS were 2.64 vs. 2.33 months, respectively (p=0.311). Also, median OS was 8.23 months for GPC and 6.75 months for PPC, respectively. Interestingly,the mOS reached 10.5 months in those patients in the GPC group without liver metastasis. OS according ECOG PS 0/1/2 were 10.9 vs. 7.8 vs. 4.4 months, respectively (p=0.004) in the GPC group of pts. Conclusions: We have identified a subgroup of pts who most benefit from FTD/TPI, characterized by ECOG PS 0, low tumor burden, indolent disease and no liver metastasis.

414 Background: At least 5% of the patients (pts) with small primary RCC initially present with metastasis. The main objective of this trial was to evaluate the role of cRFA in metastatic RCC pts with small primary tumor treated with immuno- or targeted therapy. Methods: Three parallel single-arm prospective studies were conducted. Eligibility criteria were nearly identical for all trials, and included histopathologically confirmed RCC; metastatic measurable disease; size of primary tumor ≤5 cm; good prognosis by MSKCC model; no previous therapy. Study 1: Pts were treated with percutaneous cRFA under CT guide and following IFN, 9 MIU, s.c, 3 tiw. Study 2: Pts received cRFA and following sunitinib in repeated 6-week cycles of 50 mg/day for 4 weeks, followed by 2 weeks off. Study 3: Pts with unresected primary RCC received sunitinib alone. The primary endpoint was a 33% increase in progression-free survival (PFS) over expected 5 months in study 1 and over expected 11 months in studies 2-3 (power 80%; significance .05). Sample size was 38 pts for each study. Results: Studies were comparable by baseline patient characteristics (age, gender, histology, ECOG PS, number of metastatic sites, primary tumor size). Efficacy data for 114 evaluable pts showed an objective response rate (ORR) of 8% (95% CI 4.5, 10.5) for study 1, 28.9% (95% CI 15.2, 34) for study 2, and 31.6% (95% CI 20.3, 38.9) for study 3; median PFS of 9.1 (95% CI 6.9, 10.2), 13.4 (95% CI 9.8, 14), and 12.7 (95% CI 11.3, 13.5) months for studies 1-3, respectively. ORR and PFS were significantly higher in sunitinib trials comparing with study 1 (P<.01 all differences); no differences were found between studies 2 and 3 (ORR, P=.1; PFS, P=.6). The study 1 met its primary end point, showing that PFS was significantly increased. There were no unexpected toxicities of medical treatment and complications of cRFA. Conclusions: cRFA is a safe and effective approach for select patients with metastatic RCC treated with immunotherapy. Cytoreductive ablative technique did not improve PFS in pts treated with sunitinib. Sunitinib was effective in metastatic RCC pts with unresected small primary tumor.

AbstractTrifluridine/tipiracil increases overall survival (OS) in patients with refractory, metastatic colorectal cancer (mCRC). A post hoc exploratory analysis of the RECOURSE randomized clinical trial (RCT) established two categories, a good prognosis corresponding to subjects having a low tumor burden and indolent disease. Other models in refractory mCRC are the FAS-CORRECT and Colon Life nomogram. The main objective was to externally validate the prognostic factors of the RECOURSE and FAS-CORRECT trials, and the Colon Life nomogram in a multicenter, real-world series of mCRC treated in 3rd and successive lines with trifluridine/tipiracil. The secondary aim was to develop an OS predictive model, TAS-RECOSMO. Between 2016 and 2019, 244 patients were recruited. Median OS was 8.15 vs 8.12 months for the poor (85% of the subjects) and good (15%) prognosis groups from the RESOURCE trial, respectively, log-rank p = 0.9. The most common grade 3–4 toxicities were neutropenia (17%), asthenia (6%), and anemia (5%). The AFT lognormal model TAS-RECOSMO included six variables: ECOG-PS, KRAS/NRAS/BRAF mutation status, time between diagnosis of metastasis and beginning of trifluridine/tipiracil, NLR, CEA, and alkaline phosphatase. The model’s bootstrapped bias-corrected c-index was 0.682 (95% CI, 0.636–0.722). The factors from the Colon Life model, FAS-CORRECT, and RECOURSE displayed a c-index of 0.690, 0.630, and 0.507, respectively. TAS-RECOSMO, FAS-CORRECT, and the Colon Life nomogram appear to predict OS in patients with refractory mCCR who begin trifluridine/tipiracil treatment in the real world. The prognostic groups of the RECOURCE RCT were unable to capture the situation of real-world subjects treated with trifluridine/tipiracil in this series.

350 Background: Nab-paclitaxel plus gemcitabine regimen (NABGEM) became a standard in first-line patients (pts) with metastatic pancreatic adenocarcinoma (mPAC). The AFUGEM trial evaluated the efficacy and safety of nab-paclitaxel plus simplified LV5FU2 (NABFU). Methods: Main eligibility criteria were: untreated mPAC, ECOG PS≤2. Pts received nab-paclitaxel (125 mg/m2 on d1, 8 and 15) plus gemcitabine (1000 mg/m2 on d1, 8 and 15) or plus simplified LV5FU2 (leucovorin 400 mg/m2, 5FU bolus 400 mg/m2 followed by 2400 mg/m2 given as a 46-hour continuous infusion on d1 and 15), one cycle every 4 weeks in both arms, ratio 1:2, respectively. The primary end point was observed progression-free survival (PFS) rate at 4 months (m). A Fleming 2-stage design was used with a targeted (H1) 4m-PFS rate of 50% in NABFU arm and an uninteresting 35% rate (H0, unilateral alpha of 5% and power of 80%). Results: 114 pts were included: NABGEM n=39, NABFU n=75. Baseline characteristics were well balanced: median age 66 years (45-86), ≥2 metastatic sites 36.8%, ECOG PS 0-1 84.2% and 2 15.8%, at the exception of pain more frequent in the NABFU arm (38.5% vs 56.0%). In mITT population, the observed 4m-PFS rates were of 55.4% [95% CI, 45-63] in NABFU Vs 53.9% [95% CI, 39.6-67.7] in NABGEM. Disease control rates were 65% (95% CI, 53-76) and 62% (95% CI, 45-77) respectively. After a follow-up of 24.3m, median PFS were 5.9 [95% CI, 3.6-7.4] v 4.9 months [95% CI, 2.1-7.7] [HR=0.79, 95% CI: 0.52-1.20]. Grade 3-4 adverse events were more frequent in NABGEM (77% v 87%). At tumor progression, in the NABFU arm, 50 patients (66%) and then 13 patients (17%) received a second and third line of chemotherapy respectively, versus 22 patients (56%) and 6 patients (15%) in the NABGEM arm. Median OS were 11.4 [95% CI, 8.8-16.5] v 9.2 months [95% CI, 6.0-13.6] [HR=0.61, 95% CI: 0.40-0.95], respectively. The 12 and 18-months OS rates in NABFU vs NABGEM arm were 48% Vs 41% and 34% Vs 13%, respectively. Conclusions: Nab-paclitaxel plus simplified LV5FU2 appears at least as active as gemcitabine plus nab-paclitaxel in mPAC. The toxicity profile is safe and tolerable. This regimen deserves evaluation in a phase III trial. Clinical trial information: NCT01964534.

Prognostic And Predictive Markers

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

11565 Background: TAPUR is a phase II basket study evaluating anti-tumor activity of commercially available targeted agents in pts with advanced cancers with genomic alterations. Results in a cohort of STS pts with CDK4 amplification treated with P are reported. Methods: Eligible pts had advanced STS, no standard treatment options, measurable disease, ECOG PS 0-2, and adequate organ function. Genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts received P at 125 mg orally once daily for 21 days, followed by 7 days off until disease progression. Pts matched to P had CDK4 amplification and no RB mutations. Simon 2-stage design tested the null disease control (DC) - defined as partial (PR), complete response (CR) or stable disease at 16+ weeks (SD 16+) - rate of 15% vs. 35% (power = 0.85; α = 0.10). If ≥2 of 10 pts in stage 1 have DC, 18 more pts are enrolled. If ≥7 of 28 pts have DC, the null DC rate is rejected. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: 29 pts (66% male) with STS with CDK4 amplification were enrolled from July 2016 to Nov 2019. 1 pt was not evaluable and excluded from efficacy analyses. Demographics and outcomes are summarized in Table. One pt with partial response (PR) and 12 pts with SD16+ were observed for DC and objective response (OR) rates of 48% (95% CI: 31%, 62%) and 3.7% (95% CI: 0.1%, 19%), respectively, and the null DC rate of 15% was rejected (p<0.001). 9/13 pts with DC continued on treatment for >32 weeks. 14 pts had at least one grade 3-4 AE at least possibly related to P with the most common being low WBC/platelets. Other grade 3 AEs included increased alanine aminotransferase, anemia, and fatigue. Conclusions: Monotherapy P demonstrated anti-tumor activity in heavily pre-treated pts with STS with CDK4 amplification. Additional study is warranted to confirm the efficacy of P in pts with STS with CDK4 amplification. Clinical trial information: NCT02693535. [Table: see text]

Abstract Purpose European and French guidelines for ENSAT stage IV low tumor burden or indolent adrenocortical carcinoma (ACC) recommend combination of mitotane and locoregional treatments (LRT) in first-line. Nevertheless, the benefit of LRT combination with mitotane has never been evaluated in this selected group of patients. Methods A retrospective chart review was performed from 2003-2018 of patients with stage IV ACC with ≤2 tumoral organs who received mitotane in our center. Primary endpoint was the delay between mitotane initiation and first systemic chemotherapy. Secondary endpoints were progression-free survival (PFS) and overall survival (OS) from mitotane initiation. Adjusted analyses were performed on the main prognostic factors. Results Out of 79 included patients, 48 (61%) patients were female and median age at stage IVA diagnosis was 49.8 years (interquartile-range:38.8-60.0). Metastatic sites were mainly lungs (76%) and liver (48%). Fifty-eight (73%) patients received LRT including adrenal bed radiotherapy (14 patients, 18%), surgery (37 patients, 47%) and/or interventional radiology n(35,44%). Median time between mitotane initiation and first chemotherapy administration was 9 months (Interquartile-range:4-18). Median PFS1 (first tumor-progression) was 6.0 months (CI95%:4.5-8.6). Median OS was 46 months (CI95%:41-68). PFS1, PFS2 and OS were statistically longer in the mitotane plus LRT group compared to the mitotane-only group (Hazard ratio (HR)=0.39 (CI95%:0.22-0.68), HR=0.35 (CI95%:0.20-0.63) and HR=0.27 (CI95%:0.14-0.50) respectively). Ten (13%) patients achieved complete response, all from mitotane plus LRT group. Conclusion Our results endorse European and French guidelines for stage IV ACC with ≤2 tumor-organs and favor the combination of mitotane and LRT as first-line treatment. For the first time, a significant number of complete responses were observed. Prospective studies are expected to confirm these findings.

Immune checkpoint inhibitors have revolutionized treatment and outcome of melanoma and many other solid malignancies including non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC). Unfortunately, only a minority of patients have a long-term benefit, while the remaining demonstrate primary or acquired resistance. Recently, it has been demonstrated that the prevalence of programmed death-ligand 1 (PD-L1) and tumor-infiltrating lymphocytes (TILs) varies based on the anatomical site of metastases. In particular, liver seems to have more immunosuppressive microenvironment while both the presence of lymph nodal disease and lung metastases seem to have the highest prevalence of PD-L1 and TILs. The aim of the present study is to investigate the possible role of site of metastases as a predictive factor for response or resistance to immunotherapy in several types of cancer. In this multicenter retrospective study, we enrolled patients with metastatic NSCLC, melanoma, RCC, urothelial, merkel carcinoma, and colon cancer who received immunotherapy from April 2015 to August 2019. Major clinicopathological parameters were retrieved and correlated with patients’ survival outcomes in order to assess their prognostic value and build a useful tool to assist in the decision-making process. A total of 291 patients were included in this study. One hundred eighty-seven (64%) patients were male and 104 (36%) female. The tumor histology was squamous NSCLC in 56 (19%) patients, non-squamous NSCLC in 99 (34%) patients, melanoma in 101 (35%) patients, RCC in 28 (10%) patients, and other tumors in the remaining 7 (2%) patients. The number of metastatic sites was 1 in 103 patients (35%), 2 in 104 patients (36%) and 3 in 84 patients (29%). Out of 183 valuable patients, the entity of response was complete response (CR), partial response (PR), stable disease (SD), and progression disease (PD) in 15, 53, 31, and 79 patients, respectively. Using an univariate analysis (UVA), tumor burden (p = 0.0004), the presence of liver (p = 0.0009), bone (p = 0.0016), brain metastases (p < 0.0001), the other metastatic sites (p = 0.0375), the number of metastatic sites (p = 0.0039), the histology (p = 0.0034), the upfront use of immunotherapy (p = 0.0032), and Eastern Cooperative Oncology Group (ECOG) Perfomance status (PS) ≥ 1 (p < 0.0001) were significantly associated with poor overall survival (OS). Using a multivariate analysis (MVA) the presence of liver (p = 0.0105) and brain (p = 0.0026) metastases, the NSCLC diagnosis (p < 0.0001) and the ECOG PS (p < 0.0001) resulted as significant prognostic factors of survival. Regarding the progression free survival (PFS), using a UVA of the tumor burden (p = 0.0004), bone (p = 0.0098) and brain (p = 0.0038) metastases, the presence of other metastatic sites (p = 0.0063), the number of metastatic sites (p = 0.0007), the histology (p = 0.0007), the use of immunotherapy as first line (p = 0.0031), and the ECOG PS ≥ 1 (p ≤ 0.0001) were associated with a lower PFS rate. Using an MVA, the presence of brain (p = 0.0088) and liver metastases (p = 0.024) and the ECOG PS (p < 0.0001) resulted as predictors of poor PFS. Our study suggests that the site of metastases could have a role as prognostic and predictive factor in patients treated with immunotherapy. Indeed, regardless of the histology, the presence of liver and brain metastases was associated with a shorter PFS and OS, but these results must be confirmed in further studies. In this context, a deep characterization of microenvironment could be crucial to prepare patients through novel strategies with combination or sequential immunotherapy in order to improve treatment response.

8001 Background: Erlotinib (E), a small-molecule EGFR TKI, is proven to extend survival versus placebo (P) in 2nd/3rd-line advanced NSCLC. The phase III SATURN study (BO18192) was initiated to evaluate E as maintenance therapy after standard 1st-line platinum-based chemotherapy (CT) in advanced NSCLC. Methods: Patients with no evidence of disease progression after 4 cycles of CT were randomized to receive either E 150 mg/day or P until progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS) in all patients and the co-primary endpoint was PFS in EGFR immunohistochemistry-positive (IHC+) patients. Results: A total of 1,949 patients entered the CT phase, of whom 889 were randomized to E (n=438) or P (n=451). Median age was 60 years for both arms. Baseline characteristics for E and P arms (%): male/female: 73/27 and 75/25; adenocarcinoma + BAC/squamous-cell/other: 47/38/15 and 44/43/13; stage IIIB/IV: 26/74 and 24/76; Caucasian/Asian/other: 84/14/2 and 83/15/2; ECOG PS 0/1: 31/69 and 32/68; current/former/never smoker: 55/28/18 and 56/27/17. PFS (by investigator assessment; confirmed by independent review) was significantly prolonged with E versus P in all patients (HR 0.71 [95% CI 0.62–0.82]; p<.0001) and in EGFR IHC+ patients (HR 0.69 [95% CI 0.58–0.82]; p<.0001). Subgroup analyses will be reported. Response rate was 12% with E versus 5% with P. Disease control rate (complete response + partial response + stable disease >12 wks) was 40.8% with E versus 27.4% with P (p<.0001). OS data are not yet mature. E was well tolerated: the majority of treatment-related adverse events (AEs) were grade 1/2. AEs reported in ≥10% of all patients were rash (60% with E versus 9% with P) and diarrhea (20% with E versus 5% with P); again, most were grade 1/2. Only 2.3% of patients receiving E had a serious treatment-related AE and 2.8% withdrew due to a treatment-related AE. Conclusions: The SATURN study met its primary and co-primary endpoints with high statistical significance. Erlotinib in the 1st-line maintenance setting is well tolerated, and significantly improves disease control and delays progression versus placebo across patient subgroups. [Table: see text]

e15138 Background: Bevacizumab (BEV) has shown clinical activity in metastatic colorectal cancer patients (mCRC)and randomised phase III trials have demonstrated that this agent significantly improves overall and/or progression-free survival when added to first-line irinotecan based chemotherapy (CT) regimens. We evaluated the efficacy and safety of BEV plus FOLFIRI (irinotecan, 5- fluorouracil, and leucovorin) as first line treatment in 27 consecutive metastatic colorectal cancer cases, with the primary end point to calculate the median time to clinical response with this chemotherapeutic schedule. Methods: Between October 2007 and January 2008 we collected the data on 27 patients with mCRC treated with first line chemotherapy with BEV plus FOLFIRI. Elegibility criteria had to be: mCRC; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. The treatment consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI schedule; BEV (5mg/kg) was given on day 1 with CT and then every 2 weeks until disease progression. Safety and response were assessed at the time of first CT and every 4 weeks thereafter. Results: 27 pts were evaluable (male 18; median age 61 years (range 45–77), ECOG PS 0: 52%, PS 1: 48%. The sites of metastases were: liver (15 pts), lung (5 pts), liver and lung (5 pts), peritoneal wall (2 pts).Median follow-up was 18 weeks. Two patients had complete response(CR) and 13 pts partial response (PR), with an overall response rate of 57.7%. Five patients had stable disease and 6 patients showed progressive disease. A clinical benefit was demonstrated in 77 % of pts. We observed a median time to clinical response of 11 weeks, evaluated with tumor markers and with CT/NMR/US examinations. A grade 3 or 4 neutropenia was detected in 39% of pts and grade 2 or 3 hypertension in 9%. We did’nt observe cases of thrombosis, bleeding and gastrointestinal perforation, sometimes related to the use of BEV. Conclusions: In this little experience the efficacy and safety of BEV associated with FOLFIRI schedule, a first line therapy in mCRC,is consistent with results from other previous studies, showing moreover a short time to clinical response with this association.
