Abstract
AIM Telaprevir-based therapy for chronic hepatitis C patients is effective; however, the high prevalence of dermatological reactions is an outstanding issue. The mechanism and characteristics of such adverse reactions are unclear; moreover, predictive factors remain unknown. Granulysin was recently reported to be upregulated in the blisters of patients with Stevens-Johnson syndrome (SJS). Therefore, we investigated the risk factors for severe telaprevir-induced dermatological reactions as well as the association between serum granulysin levels and the severity of such reactions. METHODS A total of 89 patients who received telaprevir-based therapy and had complete clinical information were analyzed. We analyzed the associations between dermatological reactions and clinical factors. Next, we investigated the time-dependent changes in serum granulysin levels in five and 14 patients with grade 3 and non-grade 3 dermatological reactions, respectively. RESULTS Of the 89 patients, 57 patients had dermatological reactions, including nine patients with grade 3. Univariate analysis revealed that grade 3 dermatological reactions were significantly associated with male sex. Moreover, serum granulysin levels were significantly associated with the severity of dermatological reactions. Three patients with grade 3 dermatological reaction had severe systemic manifestations including SJS, drug-induced hypersensitivity syndrome, and systemic lymphoid swelling and high-grade fever; all were hospitalized. Importantly, among the three patients, two patients' serum granulysin levels exceeded 8 ng/mL at onset and symptoms deteriorated within 6 days. CONCLUSION Male patients are at high risk for severe telaprevir-induced dermatological reactions. Moreover, serum granulysin levels are significantly associated with the severity of dermatological reactions and may be a predictive factor in patients treated with telaprevir-based therapy.

Abstract
The purpose of this study is to compare the efficacy of a single administration of dexamethasone (DEX) on day 1 against DEX administration on days 1–3 in combination with palonosetron (PALO), a second-generation 5-HT3 receptor antagonist, for chemotherapy-induced nausea and vomiting (CINV) in non-anthracycline and cyclophosphamide (AC) moderately-emetogenic chemotherapy (MEC). This phase III trial was conducted with a multi-center, randomized, open-label, non-inferiority design. Patients who received non-AC MEC as an initial chemotherapy were randomly assigned to either a group administered PALO (0.75 mg, i.v.) and DEX (9.9 mg, i.v.) prior to chemotherapy (study treatment group), or a group administered additional DEX (8 mg, i.v. or p.o.) on days 2–3 (control group). The primary endpoint was complete response (CR) rate. The CR rate difference was estimated by logistic regression with allocation factors as covariates. The non-inferiority margin was set at −15% (study treatment group − control group). From April 2011 to March 2013, 305 patients who received non-AC MEC were randomly allocated to one of two study groups. Overall, the CR rate was 66.2% in the study treatment group (N = 151) and 63.6% in the control group (N = 154). PALO plus DEX day 1 was non-inferior to PALO plus DEX days 1–3 (difference, 2.5%; 95% confidence interval [CI]: −7.8%–12.8%; P-value for non-inferiority test = 0.0004). There were no differences between the two groups in terms of complete control rate (64.9 vs 61.7%) and total control rate (49.7% vs 47.4%). Anti-emetic DEX administration on days 2–3 may be eliminated when used in combination with PALO in patients receiving non-AC MEC.

Abstract
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.

Abstract
527 Background: A few reports have shown no difference between the efficacy of infusional FU and that of oral FU (Capecitabine/S-1) for colorectal cancer, and some studies have reported the non-inferiority between infusional FU/Oxaliplatin (OX) and oral FU/OX for metastatic colorectal cancer (mCRC). We performed a sub-group comparison between infusional FU/OX (mFOLFOX6 + BV: iFU) and oral FU/OX (CapeOX/SOX + BV: oFU) from the HGCSG0802 observational cohort study with investigated Japanese patients (pts) treated with first line BV for mCRC. Methods: The objective of HGCSG0802 was to evaluate progression-free survival (PFS), overall survival (OS), time to treatment-failure (TTF), response rate (RR), safety and so on. The key eligibility criteria of HGCSG0802 were with evaluable lesions, older than 20 years, ECOG PS 0-2, and this analysis used the cohort treated with OX-based regimens.In this analysis, pts characteristics, RR and safety were compared using Fisher’s exact test. PFS and TTF were compared using log-rank test. Results: Of 108 pts (the full analysis set), 95 pts were evaluable for treated with OX-based regimens. Forty-eight pts (50.5%) were treated with iFU and 47 pts (49.5%) were treated with oFU (CapeOX + BV 42 pts/SOX + BV 5 pts). The pts characteristics between those were generally balanced except for PS 0-1 (72.9% in iFU/93.6% in oFU; p=0.012) and synchronous liver metastases (mets) (93.8% in iFU/78.8% in oFU; p=0.040). Adverse events ≥grade 3 were balanced except for leucopenia (25.0% in iFU versus 2.1% in oFU; p=0.002) and neutropenia (43.5% in iFU and 10.9% in oFU; p=0.001). Hand-foot skin reaction was not different between two cohorts. RR was 62.5% in iFU versus 71.1% in oFU (p=0.835). The median PFS was 8.3 months in iFU versus 8.2 months in oFU (p=0.835). Conclusions: The HGCSG0802 could be a database to investigate first line BV for mCRC in clinical practice. As a result of this analysis, in Japanese daily practice, efficacy was no significant difference between infusional FU/OX and oral FU/OX, and the profiles of adverse events varied from each regimens.

Abstract
BACKGROUND AND PURPOSE Elevation of glutamate, an excitatory amino acid, during inflammation and injury plays a crucial role in the reception and transmission of sensory information via ionotropic and metabotropic receptors. This study aimed to investigate the mechanisms underlying the biphasic effects of metabotropic glutamate mGlu5 receptor activation on responses to noxious heat. EXPERIMENTAL APPROACH We assessed the effects of intraplantar quisqualate, a non-selective glutamate receptor agonist, on heat and mechanical pain behaviours in mice. In addition, the effects of quisqualate on the intracellular calcium response and on membrane currents mediated by TRPV1 channels, were examined in cultured dorsal root ganglion neurons from mice. KEY RESULTS Activation of mGlu5 receptors in hind paw transiently increased, then decreased, the response to noxious heat. In sensory neurons, activation of mGlu5 receptors potentiated TRPV1-mediated intracellular calcium elevation, while terminating activation of mGlu5 receptors depressed it. TRPV1-induced currents were potentiated by activation of mGlu5 receptors under voltage clamp conditions and these disappeared after washout. However, voltage-gated calcium currents were inhibited by the mGlu5 receptor agonist, even after washout. CONCLUSIONS AND IMPLICATIONS These results suggest that, in sensory neurons, mGlu5 receptors biphasically modulate TRPV1-mediated intracellular calcium response via transient potentiation of TRPV1 channel-induced currents and persistent inhibition of voltage-gated calcium currents, contributing to heat hyper- and hypoalgesia.

Abstract
BACKGROUND Transarterial chemoembolisation (TACE) is a standard treatment for unresectable, intermediate stage hepatocellular carcinoma (HCC). Survival after TACE, however, can be highly variable, with no suitable biomarker predicting therapeutic outcome. The inflammation-based index (IBI) has previously been shown to independently predict overall survival (OS) in all stages of HCC. AIM To explore the prognostic ability of IBI as a predictor of survival after TACE. METHODS Baseline staging, biochemical and clinicopathological features including IBI were studied in a derivation set of 64 patients undergoing TACE for intermediate stage HCC. Dynamic changes in IBI before and after TACE were studied as predictors of survival using both a univariate and multivariate Cox regression model and further validated in two independent patient cohorts from Korea (n = 76) and Japan (n = 577). RESULTS Pre-treatment IBI predicted for OS in the derivation set (P = 0.001). Other univariate predictors of OS included radiological response to TACE (P < 0.001), pre-TACE CLIP score (P < 0.01), tumour diameter >5 cm (P = 0.05) and AFP ≥400 (P < 0.001). Normalisation of IBI post-TACE was associated with radiological response by mRECIST criteria and improved OS (P < 0.001). Normalisation of IBI remained a significant multivariate predictor of OS in both the derivation and validation sets (P < 0.001). CONCLUSIONS Normalisation of IBI after TACE is shown to be an independent predictor of survival and may be integrated into the retreatment criteria for repeat TACE in intermediate stage HCC. IBI and its dynamic changes after treatment are validated as a biomarker allowing the stratification of patients with a significant survival advantage following initial TACE.

Abstract
BACKGROUND GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma [HCC] and Of its treatment with sorafeNib) is a global, prospective, non-interventional study undertaken to evaluate the safety of sorafenib in patients with unresectable HCC in real-life practice, including Child-Pugh B patients who were excluded from clinical trials. METHODS Patients with unresectable HCC, for whom the decision to treat with sorafenib, based on the approved label and prescribing guidelines, had been taken by their physician, were eligible for inclusion. Demographic data and disease/medical history were recorded at entry. Sorafenib dosing and adverse events (AEs) were collected at follow-up visits. The second interim analysis was undertaken when ~1500 treated patients were followed up for ≥ 4 months. RESULTS Of the 1571 patients evaluable for safety, 61% had Child-Pugh A status and 23% Child-Pugh B. The majority of patients (74%) received the approved 800 mg initial sorafenib dose, regardless of Child-Pugh status; however, median duration of therapy was shorter in Child-Pugh B patients. The majority of drug-related AEs were grade 1 or 2, and the most commonly reported were consistent with previous reports. The incidence and nature of drug-related AEs were broadly similar across Child-Pugh, Barcelona Clinic Liver Cancer (BCLC) and initial dosing subgroups, and consistent with the overall population. CONCLUSIONS Consistent with the first interim analysis, overall safety profile and dosing strategy are similar across Child-Pugh subgroups. Safety findings also appear comparable irrespective of initial sorafenib dose or BCLC stage. Final analyses in > 3000 patients are ongoing.

Abstract
603 Background: The safety and efficacy of first-line IRIS (S-1 in combination with irinotecan) and IRIS/Bev (IRIS in combination with bevacizumab [Bev]) have been evaluated in patients with metastatic colorectal cancer (mCRC). To date, no randomized studies comparing these regimens have been performed. This retrospective analysis compared efficacy data for the two regimens from separate phase II studies performed at Hokkaido Gastrointestinal Cancer Study Group (HGCSG). Methods: Patients with histologically confirmed unresectable metastatic or recurrent CRC and received no prior chemotherapy were enrolled. In the first trial, patients received irinotecan 100 mg/m2 on day 1,15 and oral S-1 40 mg/m2 twice daily on days 1-14 every 4 weeks (IRIS study: HGCSG0302). In the second trial, patients received the same regimen plus Bev 5 mg/kg on day 1,15 (IRIS/Bev study). Results: A total of 40 and 52 patients were enrolled the IRIS and IRIS/Bev studies, respectively. Patient characteristics were generally similar in both groups, whereas there were more cases of good performance status and less number of metastatic organ in IRIS/Bev group. The median overall survival was 39.6 months in IRIS/Bev, as compared with 23.4 months in IRIS, corresponding to a hazard ratio for death of 0.418 (p<0.001). The median progression-free survival was 17.0 months in IRIS/Bev, as compared with 8.6 months in IRIS (hazard ratio for disease progression, 0.402; p < 0.001); the corresponding response rate were 63.5 percent and 52.5 percent (p = 0.393). In a multivariate analysis of PFS and OS, IRIS/Bev was significantly associated with longer PFS and OS compared with IRIS alone. Conclusions: In this retrospective comparison of two studies, the addition of Bev to IRIS appeared to improve outcome compared with IRIS alone in the first-line treatment of patients with mCRC.

634 Background: In the treatment for mCRC, it is essential for understanding the prognosis of each individual patient. Köhne’s index (KI) based on performance status, white blood cell count, alkaline phosphatase and number of metastatic sites has been previously proposed. However, in the salvage setting, the validity of KI has not been reported in patients treated by cetuximab-based chemotherapy. Methods: 269 patients with mCRC treated by cetuximab contained chemotherapy were retrospectively registered from 27 centers in Japan. This analysis was included in the KRAS wild-type patients who were refractory to or intolerant for 5-FU/irinotecan/oxaliplatin and were never administered anti-EGFR-antibody. Univariate and multivariate analysis for overall survival were performed using patient characteristics. Survival analyses were performed with Kaplan-Meier method, log-rank test and Cox proportional hazards model. The analysis was also designed to determine whether the Köhne’s classification could be extended to other endpoints such as progression-free survival. Results: All data were available for prognostic categorization in 127 patients. Median overall and progression-free survival was 9.8 and 4.2 months. The distribution and median survival / progression-free survival for KI were as follows: low risk (L) (n = 40; 13.1/5.1 months), intermediate risk (I) (n = 17; 9.6/3.5 months), and high risk (H) (n = 70; 7.6/4.1 months). For overall survival, there was significant difference between L and H (p = 0.004), but not between L and I (p = 0.213), and between I and H (p = 0.321). For progression-free survival, there was tended to difference between L and H (p = 0.083), but not between L and I (p = 0.392), and between I and H (p = 0.630). In Cox multivariate analysis, KI showed an independent prognostic impact (HR 1.370, p = 0.010), but not predictive impact (HR 1.147, p = 0.212). Conclusions: In this analysis, KI might be a prognostic factor in salvage treatment with cetuximab-based regimen, but no effect predicted impact. Moreover, the prospective evaluation is needed for the further validation.

Abstract
113 Background: On the basis of SPIRITS trial, S-1 plus cisplatin has been regarded as standard first-line chemotherapy for patients with advanced gastric cancer (AGC) in Japan (Koizumi W, et al. Lancet Oncol, 2008). However, conventional S-1 plus cisplatin (60mg/m2) regimen requires hospitalization for hydration. Therefore, we conducted phase II trial of S-1 plus split Cisplatin (SSP) for outpatient chemotherapy. Methods: Eligibility criteria included pathologically confirmed AGC; no prior chemotherapy; Age 20 to 75, ECOG performance status (PS) of 0 to 1; adequate organ function; and written informed consent. S-1 (40 mg/m2) was given orally, twice daily for 21 days, and cisplatin (30 mg/m2) was given intravenously on day 1 and 15, followed by 2-week rest period, within a 5-week cycle. Primary endpoint was the response rate (RR), and secondary endpoints were progression-free survival, overall survival, safety profile, and non-hospitalized survival. Results: Between Mar 2008 and Mar 2012, 40 pts were enrolled. Patients characteristics were as follows: median age 63 years (range 41-75), Male: female 30:10, PS 0:1 33:7, diffuse: intestinal 23:17. Median number of cycles was 3. The main grade 3-4 AE were neutropenia (37.5%), anemia (30%), anorexia (30%) and fatigue (15%). These toxicities were safely managed. The median relative dose intensity of S-1 was 0.782, and cisplatin was 0.824. Response rate was 57.5% (95%CI 42.2-72.8%) and disease control rate was 90.0%. Median progression-free survival was 6.1 months (95%C.I. 3.0-9.1 months) and median survival time was 15.8 months (95%C.I. 12.7-18.8 months). Conclusions: SSP showed comparable tolerability and efficacy to SPIRITS trial. In addition, most patients underwent the treatment without hospitalization. SSP may be one of practical alternatives for AGC.

Abstract
598 Background: Cmab and Pmab have antitumor activity and acceptable safety profiles in patients (pts) with mCRC. Although IRI-based chemotherapy combined with Cmab or Pmab has demonstrated the effectiveness in salvage-line, there has been no reported trials comparing these antibodies directly. Methods: Data of 96 pts with mCRC treated by Cmab plus IRI-based chemotherapy (Cmab/IRI) from HGCSG 0901 and 27 pts treated by Pmab plus IRI-based chemotherapy (Pmab/IRI) from HGCSG1002 were retrospectively analyzed. All patients with KRAS wild type were refractory to or intolerant for 5-FU/ irinotecan/ oxaliplatin and also were never administered anti-EGFR-antibodies. Survival analyses were performed with Kaplan-Meier method, log-rank test and Cox proportional hazards model. Results: Patient characteristics were as below (Cmab/IRI vs. Pmab/IRI); male/female 58/38 vs. 16/11, median age (range) 63(38-80) vs. 64(49-81), PS 0/1/2 52/35/9 vs. 21/6/0, number of metastatic organs 1/2/3- 29/37/30 vs. 6/12/7, prior bevacizumab administration 62.5% vs. 92.6% (p = 0.002). MST was 9.9 months in the Cmab/IRI and 14.9 months in the Pmab/IRI (p = 0.196). PFS was 4.8 months in the Cmab/IRI, as compared with 5.4 months in the Pmab (p = 0.083); the corresponding RR was 25.0 % and 18.5% (p = 0.611). After adjusting other prognostic factors with Cox proportional hazard model, the administration of Cmab/Pmab made significant difference neither for OS (HR 0.908, 95% CI 0.513-1.610, p = 0.742), nor PFS (HR 0.732, 95% CI 0.447-1.199, p = 0.732). Conclusions: In this integration analysis of two studies, there were no significant difference in efficacy between Cmab and Pmab with IRI-based chemotherapy in the salvage-line treatment of pts with mCRC.
