237 Background: Results from the phase III PRODIGE 4/ACCORD 11 trial provided one of current standard regimens for advanced pancreatic cancer (PC), consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX), which has superior response rate (RR) and survival benefit even with severe toxicity (Thierry C, et al. N Engl J Med 2011;364:1817-1825). There are several reports on the correlation between early tumor shrinkage (ETS) or depth of response (DpR) and survival in chemotherapies for colorectal cancer; however, few studies have investigated it in PC. We therefore analyzed retrospectively whether the ETS will predict outcomes in pts with PC treated with FOLFIRINOX therapy. Methods: Advanced PC pts with ECOG PS of 0 or 1, who received FOLFIRINOX as 1st- or 2nd-line treatment between November 2012 and July 2015 in 3 institutes of Showa University were included in this analysis. ETS was defined as a reduction ≥ 20% of target lesions’ diameters measured at 8 weeks from treatment start. We evaluated the association of ETS with progression-free survival (PFS) and overall survival (OS) but also addressed the correlation between outcomes and DpR, which was percentage of maximal tumor shrinkage observed at the nadir diameter compared with baseline. Results: Fifty-nine PC pts with median age of 63 (range 34-76) years and males of 68% were enrolled: 80% of pts had metastatic disease. In the population, RR, median PFS, and OS were 28%, 5.4 months, and 10.7 months, respectively. Among 46 (78%) evaluable pts for the ETS, 12 (26%) pts experienced ETS. The PFS was significantly longer in pts with ETS compared to pts with no ETS (9.0 vs. 4.2 months, HR 0.43, 95%CI 0.17-0.96, log-rank P= 0.045). Moreover, pts with ETS had a better OS although no statistical significance (HR 0.53, log-rank P= 0.25). Median DpR was 11.1% (from -75.7 to 100), and the correlation of DpR with clinical outcome was observed (P= 0.024 for PFS, P= 0.22 for OS). Conclusions: This retrospective analysis suggests that the early response to FOLFIRINOX treatment may predict better outcomes in pts with advanced PC. The ETS may serve as a novel predictor of prolonged survival time in PC pts treated with FOLFIRINOX.

Early tumor shrinkage (ETS) and depth of response (DoR) predict favorable outcomes in metastatic colorectal cancer. We aim to evaluate their prognostic role in metastatic pancreatic cancer (PC) patients treated with first-line modified-FOLFIRINOX (FOLFOXIRI) or Gemcitabine + Nab-paclitaxel (GemNab). Hence, 138 patients were tested for ETS, defined as a ≥20% reduction in the sum of target lesions’ longest diameters (SLD) after 6–8 weeks from baseline, and DoR, i.e., the maximum percentage shrinkage in the SLD from baseline. Association of ETS and DoR with progression-free survival (PFS) and overall survival (OS) was assessed. ETS was reached in 49 patients (39.5% in the FOLFOXIRI, 29.8% in the GemNab group; p = 0.280). In the overall population, ETS was significantly associated with better PFS (8.0 vs. 4.8 months, p < 0.001) and OS (13.2 vs. 9.7 months, p = 0.001). Median DoR was −27.5% (−29.4% with FOLFOXIRI and −21.4% with GemNab, p = 0.016): DoR was significantly associated with better PFS (9.0 vs. 6.7 months, p < 0.001) and OS (14.3 vs. 11.1 months, p = 0.031). Multivariate analysis confirmed both ETS and DoR are independently associated with PFS and OS. In conclusion, our study added evidence on the role of ETS and DoR in the prediction of outcome of PC patients treated with first-line combination chemotherapy.

Abstract Background The prognostic potential of early tumor shrinkage (ETS) and depth of response (DpR) in pancreatic cancer (PC) is unclear. Here, we recruited 90 patients with recurrent and metastatic PC (RMPC) who had received chemotherapy as first-line therapy to assess the prognostic potential of these markers. Methods ETS is characterized as a ≥ 20% depletion in the sum-of-the-longest-diameters (SLD) of measurable tumor lesions at 6–12 weeks than the baseline. DpR is the maximum shrinkage (%) from the baseline to nadir. We evaluated corrections in ETS and DpR with survival. Results Of the 63 patients in which ETS assessment was possible, 21 (33.3%) achieved ETS. We found a significant association between the incidence of ETS and an improved rate of progression-free survival (PFS; 6.5 vs. 2.2 months; p < 0.001) and overall survival (OS; 12.1 vs. 6.0 months; p = 0.014). The median value of DpR was − 23.66%. DpR was also related to improved PFS (9.3 vs. 3.1 months; p < 0.001) and OS (18.2 vs. 7.3 months; p < 0.001). Patients who had distant metastasis, not local recurrence, with ETS showed markedly better outcomes. In a multivariate model, both ETS and DpR were independent predictors of OS in the whole population. Conclusions ETS and DpR may predict favorable outcomes for RMPC patients who had received chemotherapy as first-line therapy, independent of the agents used. Further studies on the exploratory analyses of the optimum ETS cut-off value in recurrent PC patients to predict favorable clinical outcomes are required.

BackgroundPreliminary evidence indicates that early tumor shrinkage (ETS) following immune checkpoint inhibitor (ICI) initiation may be associated with survival outcomes in patients with advanced melanoma. ETS has not been explored as a biomarker of survival outcomes or patient-reported outcomes in patients with advanced non-small cell lung cancer (NSCLC) treated with ICIs.MethodsThe study pooled data from patients with NSCLC in the randomized trials OAK and POPLAR (atezolizumab vs docetaxel; n=1464), and single-arm atezolizumab trials BIRCH and FIR (n=797). The association between ETS (≥10% decrease in pretreatment sum-of-longest diameters of target-lesions at 6 weeks) and overall survival (OS), progression-free survival (PFS), time to deterioration (TDD) in health-related quality-of-life (HRQoL) and physical function (PF) was assessed using Cox proportional hazard analysis.ResultsETS occurred in 20% of atezolizumab-treated patients with NSCLC within OAK and POPLAR and was associated with highly favorable OS (HR 0.33, p<0.001), PFS (HR 0.31, p<0.001), TDD in HRQoL (HR 0.73, p=0.01) and PF (HR 0.52, p<0.001). The results were replicated in the BIRCH and FIR data. Atezolizumab-treated patients achieving ETS had markedly improved OS compared with docetaxel-treated patients achieving ETS (24-month OS 55% vs 32%); PFS was also markedly improved (24-month PFS 31% vs 4%). In contrast, for patients not achieving ETS, atezolizumab-treatment was associated with more modest OS (24-month OS 23% vs 20%) and PFS (24-month PFS 3% vs 1%) improvement compared with docetaxel. Overall, the effect size for ETS within the atezolizumab-treated patients was significantly greater than that in the docetaxel-treated patients (P(interaction)=0.002 for OS and P(interaction)<0.001 for PFS).ConclusionsETS is an easily measurable biomarker, predictive of highly favorable survival and patient-reported outcomes with atezolizumab treatment for advanced NSCLC. Further, ETS identifies patients with significantly greater treatment benefit for ICI therapy.

We investigated the association between early tumor shrinkage (ETS) and treatment outcome in patients with hepatocellular carcinoma treated with lenvatinib (LEN). A retrospective analysis was performed in 104 patients. ETS was defined as tumor shrinkage at the first evaluation in the sum of target lesions’ longest diameters from baseline according to the Response Evaluation Criteria in Solid Tumors (RECIST). The median overall survival (OS) was not reached, whereas the median progression-free survival (PFS) was 5.0 months. The receiver operating characteristic curve analysis in differentiating long-term responders (PFS ≥ 5.0 months) from short-term responders (PFS < 5.0 months) revealed an ETS cut-off value of 10%. ETS ≥ 10% was significantly correlated with better PFS and OS compared with ETS < 10%. Additionally, ETS ≥ 10% showed a better discrimination ability on prognosis compared with modified RECIST-based objective response at the first evaluation. Multivariate analysis confirmed ETS ≥ 10% as an independent predictor of better OS, as well as a Child–Pugh score of 5 and macrovascular invasion. In conclusion, ETS ≥ 10% was strongly associated with outcome in patients treated with LEN. This biomarker could allow earlier assessment of the treatment response and guide treatment decision-making for HCC.

Purpose To determine whether addition of the farnesyltransferase inhibitor tipifarnib (Zarnestra, R115777; Johnson and Johnson Pharmaceutical Research and Development, Beerse, Belgium) to standard gemcitabine therapy improves overall survival in advanced pancreatic cancer. Patients and Methods This randomized, double-blind, placebo-controlled study compared gemcitabine + tipifarnib versus gemcitabine + placebo in patients with advanced pancreatic adenocarcinoma previously untreated with systemic therapy. Tipifarnib was given at 200 mg bid orally continuously; gemcitabine was given at 1,000 mg/m2 intravenously weekly × 7 for 8 weeks, then weekly × 3 every 4 weeks. The primary end point was overall survival; secondary end points included 6-month and 1-year survival rates, progression-free survival, response rate, safety, and quality of life. Results Six hundred eighty-eight patients were enrolled. Baseline characteristics were well balanced between the two treatment arms. No statistically significant differences in survival parameters were observed. The median overall survival for the experimental arm was 193 v 182 days for the control arm (P = .75); 6-month and 1-year survival rates were 53% and 27% v 49% and 24% for the control arm, respectively; median progression-free survival was 112 v 109 days for the control arm. Ten drug-related deaths were reported for the experimental arm and seven for the control arm. Neutropenia and thrombocytopenia grade ≥ 3 were observed in 40% and 15% in the experimental arm versus 30% and 12% in the control arm. Incidences of nonhematologic adverse events were similar in two groups. Conclusion The combination of gemcitabine and tipifarnib has an acceptable toxicity profile but does not prolong overall survival in advanced pancreatic cancer compared with single-agent gemcitabine.

LBA4004 Background: GV1001, a promiscuous class II epitope encompassing aa 611-626 of hTERT led to the development of CD4+ clones recognizing hTERT in patients with advanced pancreatic cancer (APC). Preclinically gemcitabine increases antigen cross-presentation, enhances T cell trafficking/activation, and reduces MDSCs and Tregs. Methods: Patients with APC were randomized 1:1:1 to: Arm 1 GemCap; 2 GemCap for 8/52 followed by GV1001 followed by further GemCap if no PD at week 8; 3 concurrent administration of GemCap and GV1001. 735 (69.2%) had metastatic disease and 948 (89.3%) had ECOG PS=0 or 1. Randomization was stratified by stage and PS. Primary endpoint was overall survival (OS); secondary endpoints included ORR, TTP, and AEs. Recruitment target was 1,110 patients (780 deaths) to permit detection of a hazard ratio of 0.748 between either GV1001 arm and Arm 1 using a 2-sided α=0.025 level of significance with at least 80% power. Results: 1,062 pts from 51 centers were randomized. Trial maturity was high (72.7% patients died): median follow-up was 6.11 months. The overall response rates were Arm 1=17.6%; Arm 2=8.9% (p=0.001); Arm 3: 15.5% (p=0.460 compared with Arm 1). Conclusions: OS with concurrent GemCap/GV1001 was not different to that with GemCap alone. OS with sequential GV1001 was not statistically different to GemCap alone as it did not meet the criterion for statistical significance (p<0.0175). The addition of a T helper epitope vaccine to GemCap did not improve outcome compared to GemCap alone. Clinical trial information: 43482138. [Table: see text]

PurposeBoth gemcitabine (GEM) and fluoropyrimidines are valuable treatment for advanced pancreatic cancer. This open-label study was designed to compare the overall survival (OS) of patients randomly assigned to GEM alone or GEM plus capecitabine (GEM-CAP).Patients and MethodsPatients with previously untreated histologically or cytologically proven locally advanced or metastatic carcinoma of the pancreas with a performance status ≤ 2 were recruited. Patients were randomly assigned to GEM or GEM-CAP. The primary outcome measure was survival. Meta-analysis of published studies was also conducted.ResultsBetween May 2002 and January 2005, 533 patients were randomly assigned to GEM (n = 266) and GEM-CAP (n = 267) arms. GEM-CAP significantly improved objective response rate (19.1% v 12.4%; P = .034) and progression-free survival (hazard ratio [HR], 0.78; 95% CI, 0.66 to 0.93; P = .004) and was associated with a trend toward improved OS (HR, 0.86; 95% CI, 0.72 to 1.02; P = .08) compared with GEM alone. This trend for OS benefit for GEM-CAP was consistent across different prognostic subgroups according to baseline stratification factors (stage and performance status) and remained after adjusting for these stratification factors (P = .077). Moreover, the meta-analysis of two additional studies involving 935 patients showed a significant survival benefit in favor of GEM-CAP (HR, 0.86; 95% CI, 0.75 to 0.98; P = .02) with no intertrial heterogeneity.ConclusionOn the basis of our trial and the meta-analysis, GEM-CAP should be considered as one of the standard first-line options in locally advanced and metastatic pancreatic cancer.

4615 Background: Gemcitabine monotherapy is the current standard for patients with advanced pancreatic cancer (PC). Its efficacy, however, varies significantly depending on individuals. This study was aimed at discovering a new diagnostic biomarker that can estimate the outcome of patients after receiving the therapy. Methods: All patients included in this study (304 patients) had metastatic PC and received at least two cycles of gemcitabine monotherapy. We compared the baseline plasma proteome between representative 29 short-term survivors (survived for less than 100 days) and 31 long-term survivors (survived for more than 400 days) using quantitative mass spectrometry (MS). Results: Among a total of 45,277 peptide peaks, we identified 637 peaks whose intensities were significantly different (p<0.001, Welch's t-test). The 2 MS peaks with the highest statistical significance (p=2.57×10-4 and 5.03×10-4) were revealed to be derived from α1-antitrypsin (AT) and α1-antichymotrypsin (ACT), respectively, by tandem MS. The levels of AT and ACT, WBC count, platelet count, alkaline phosphatase, and ECOG performance status were selected using a forward stepwise procedure by Akaike's information criterion, and a scoring system (nomogram) was constructed to estimate the prognosis of individual patients. Among the selected parameters the AT level was found to be the second most significant contributor to the nomogram (p=0.0003; Table ). This survival prediction model was internally validated using a bootstrap approach with 200 resamples. Conclusions: Our survival prediction model including values of AT and ACT seems to have high practical utility and may lead to tailoring the treatment of patients with advanced PC. Modification of therapeutics may need to be taken into consideration for patients with increased AT and ACT. [Table: see text] [Table: see text]
