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.

4631 Background: Several novel targeted agents significantly prolong overall survival (OS) in metastatic renal cell cancer (mRCC) patients (pts.). Translational research, however, has not identified any prospectively validated prognostic or predictive biomarkers. Recently, progression free survival (PFS), overall response rate (ORR) and early tumor shrinkage were proposed as putative predictors for clinical outcome. In this study we aim to explore the potential role of treatment induced tumor remission as a prognostic or predictive parameter in mRCC. Methods: In our analyses we investigated the putative prognostic role of best response according to RECIST 1.1 criteria (complete remission (CR), partial remission (PR), stable disease (SD), progressive disease (PD)) in first line Tyrosine-kinase inhibitor (TKI) treatment in n=83 pts. Responders were defined by achieving CR, PR or SD at any time during the course of treatment. Furthermore, we tested whether tumor shrinkage of 10% or more within 12 weeks of treatment qualifies as a potential cut-off-parameter to predict PFS or OS. Uni- and multivariate analyses were performed using Log-rang test, Kaplan-Meier-, and Cox-regression analysis. Results: Univariate analyses revealed that first-line treatment non-responders had a significantly shorter OS than responders (p <0.0001). Tumor shrinkage of <10% or ≥10% also correlated with an OS of 14.5 vs. 29.1 mo. (p=0.001) and a PFS of 3.0 vs. 11.5 mo. (p <0.001). In multivariate analyses tumor shrinkage of ≥10% was tested with other common variables such as ECOG, MSKCC-score, histology, and metastatic sites and proved to be a significant independent prognostic (HR 0.361; 95% CI 0.156-0.833) and predictive (HR 0.306; 95% CI 0.152-0.612) parameter. Conclusions: Our results outline that sensitivity to first line treatment of mRCC is an important prognostic factor in mRCC. Hereby tumor shrinkage of ≥10% within 12 weeks of treatment reveals a novel cut-off-parameter, which showed to be a promising prognostic and predictive marker in mRCC. Further investigations are needed to validate this parameter.

631 Background: Early tumor shrinkage (ETS) and depth of response (DoR) predict overall survival (OS) in first-line chemotherapy + anti-EGFR monoclonal antibodies in KRAS wild-type metastatic colorectal cancer (mCRC). This association and the predictive accuracy of response measurements were investigated in the first-line setting for FOLFOX/FOLFIRI plus cetuximab. Methods: We performed a study of FOLFOX/FOLFIRI plus cetuximab as first-line treatment in Indian patients with KRAS wild-type mCRC. The primary endpoint was response rate (RR), and secondary endpoints included progression-free survival (PFS), overall survival (OS), and safety. Radiologic assessments at week 8 were used to calculate the relative change in the sum of the longest diameters of the target lesions. Cox regression models analysis investigated associations between ETS and overall survival (OS) and progression-free survival (PFS). Results: Sixty (78.9 %) of 76 patients had ETS, which was associated with prolonged PFS and OS. Both ETS and DoR were able to predict survival as accurately as RECIST response. Both ETS and DoR were associated with PFS and OS at the univariate analyses and in the multivariate models stratified for other prognostic variables. In the study patients, the RR, median PFS, and OS were 68.4 %, 13.1 months, and 30.6 months, respectively. Median DpR was 52%. The DpR correlated with OS as well as PFS. FOLFOX plus cetuximab was active as a first-line, with no major toxicities. Conclusions: Our prospective evaluation of chronological tumor shrinkage showed that ETS and DpR correlate with outcomes in patients with KRAS wild-type mCRC who receive cetuximab-based chemotherapy. Achieving rapid and deep tumor shrinkage consistently delays tumor progression and prolongs survival in patients treated with first-line chemotherapy plus cetuximab. ETS is a promising and valuable end point for clinical trials’ design deserving further investigation.

749 Background: It was reported that early tumor shrinkage (ETS) was associated with better overall survival (OS) in patients (pts) with metastatic colorectal cancer (mCRC) receiving cetuximab. We investigated association of ETS with progression free survival (PFS) in pts with unresectable colorectal liver metastases (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 and so on. The key eligibility criteria were evaluable lesions, older than 20 years old, ECOG PS 0-2. In this analysis, association of ETS at 8 weeks from the start of chemotherapy with pts characteristics, PFS and TTF was evaluated. Pts characteristics were compared using Student-t test, chi-square test and Fisher’s exact test. PFS and TTF were analyzed with Kaplan-Meier method and compared using log-rank test. Univariate analysis for the association of pts characteristics with PFS and TTF was performed using log-rank test, and multivariate analysis was performed using Cox proportional hazards model. Results: Of 108 pts (the full analysis set), 74 pts with CLM were evaluable for ETS. Forty-nine pts (66.2%) had ETS ≥20%. The pts characteristics between ETS ≥20% and <20% were well balanced. The median PFS was 7.3 months in ETS <20% versus 10.0 months in ETS ≥20% (HR 0.55; p=0.025). In multivariate analysis for PFS, there was no significant difference between ETS ≥20% and <20% (HR 0.585; p=0.066). The median TTF (ETS <20% v ≥20%) was 5,1 months vs. 7.7 months (HR 0.46; p=0.003). In multivariate analysis for TTF, there was significant difference between ETS ≥20% and <20% (HR 0.509; p=0.017). Conclusions: In this analysis, ETS ≥20% might be positive predictive marker for PFS and TTF in pts with CLM receiving first-line BV-based chemotherapy.

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.

3586 Background: Recent evidence suggests that benefit from anti-EGFR treatment is restricted to RAS wild-type left-sided colorectal cancer (LC) (Holch JW et al. Eur J Cancer 2017). However, these results are preliminary. We therefore investigated patients with RC enrolled in the FIRE-3 trial, which evaluated the efficacy of first-line FOLFIRI plus either cetuximab (cet) or bevacizumab (bev) in RAS wildtype mCRC. New metrics of tumor dynamics were used to characterize the patients. Methods: The splenic flexure was used to differentiate LC from RC. Survival analysis was done using Kaplan-Meier estimation and differences were expressed using Log-Rank test, hazard ratios (HR) and corresponding 95% confidence intervals. Central independent radiological data was used to calculate early tumor shrinkage ≥20% (ETS) and depth of response (DpR). Results: In total, 330 patients were assessable for central radiological evaluation. In patients with LC (n = 257), treatment with FOLFIRI + cet led to longer overall survival (OS) compared to FOLFIRI + bev (HR = 0.68, p = 0.016). In patients with RC (n = 68), OS was comparable between treatment arms (HR = 1.11, p = 0.715). In patients with RC and ETS < 20%, OS was inferior in patients treated with FOLFIRI + cet. In patients who reached ETS ≥20%, a comparable OS was evident between treatment arms (for further details of efficacy in patients with RC see table). Conclusions: Patients with RC do not represent a uniform population. ETS ≥20% defines a subgroup of patients where comparable treatment efficacy was observed with regard to OS, ORR and DpR by addition of cetuximab vs. bevacizumab to FOLFIRI. [Table: see text]

Abstract Neutropenia is a common side effect associated with nab-paclitaxel gemcitabine (Nab-Gem) therapy. We retrospectively investigated the association between neutropenia induced by first-line Nab-Gem and survival in metastatic pancreatic carcinoma patients. Metastatic pancreatic patients treated with first-line Nab-Gem were included in this retrospective analysis. Neutropenia was categorized using the National Cancer Institute Common Toxicity Criteria scale. Outcome measures were overall survival (OS), progression-free survival (PFS) and response rate. 115 patients were analyzed. Median PFS was 7 months (95% CI 5–8) for patients with grade ≥ 3 neutropenia and 6 months (95% CI 5–6) for patients with grade < 3 neutropenia [p = 0.08; hazard ratio (HR 0.68)]. Median OS was 13 months (95% CI 10–18) for patients with grade ≥ 3 neutropenia and 10 months (95% CI 8–13) for patients with grade < 3 neutropenia (p = 0.04; HR 0.44). In multivariate analysis, the occurrence of grade ≥ 3 neutropenia showed a statistically significant association with OS (HR 0.62; 95% CI 0.09–0.86; p = 0.05). Nab-Gem-induced neutropenia is associated with longer survival in metastatic pancreatic cancer patients.

Abstract Purpose: To compare the efficacy and toxicity of three different chemotherapy regimens used as first-line treatments in the real-life management of metastatic pancreatic cancer (mPC). Methods: A total of 218 patients diagnosed with mPC at the time of initial admission were included in this multicenter study. Gemcitabine (Gem, n=71), Gemcitabine-cisplatin (Gem-Cis, n=91) and FOLFIRINOX (FFX, n=56) treatments were compared in terms of efficacy and treatment-related toxicity. Results: Overall response rate was significantly higher in the FFX group (50.0%) than in the Gem (28.2%) and Gem-Cis (27.5%) groups (p=0.010).Median progression-free survival (8.4 vs. 4.6 and 5.5 months, respectively, p<0.001) and overall survival (16.4 vs. 8.1 and 8.7 months, respectively, p=0.002) were significantly longer in theFFX group than in the Gem and Gem-Cis groups. Toxicity of any grade was noted in 46(64.8%), 56(61.5%) and 49(87.5%) patients in the Gem, Gem-Cis and FFX groups, respectively (p=0.003).Of the grade 3-4 toxicities, weakness/fatigue and mucositis were reported only in the FFX group (5.4% and 3.6%, respectively). Grade 3-4 diarrhea (10.7%, 0.0%, 2.2%, respectively) and neutropenia (25%, 4.2% and 5.5%, respectively) were more common in the FFX group than in the Gem and Gem-Cis groups. Conclusion: In conclusion, our findings indicate that FFX regimen provides a significant advantage over the other treatment regimens in terms of response rates and survival. Treatment toxicity was more frequent but manageable with the FFX regimen.FFX seems to be a preferable regimen in the first-line treatment of the younger and fit patients diagnosed with mPC.
