4069 Background: The survival benefit of using a combination therapy instead of keeping it for a second line (L2) has not been demonstrated in metastatic colorectal cancer. The purpose of this trial was to compare the efficacy of simplified LV5FU2 (s) followed by FOLFOX6 (arm A) to FOLFOX6 followed by FOLFIRI (arm B) on progression-free survival after two lines of chemotherapy. We present here preliminary results relating to toxicity, observance and overall survival. Methods: Inclusion criteria: a) non resectable metastases of histologically proven colorectal adenocarcinoma , b) evaluable disease (WHO criteria), c) absence of previous chemotherapy other than adjuvant. Treatment was as follows: LV5FU2s = at day 1, folinic acid 400 mg/m2, 5-FU bolus 400 mg/m2 and continuous infusion over 46 hours 2,400 mg/m2/2 weeks; FOLFOX6 = LV5FU2s + oxaliplatin 100 mg/m2 at day 1; FOLFIRI = LV5FU2s + irinotecan 180 mg/m2 at day 1. Results: 410 pts out of 570 initially planned (early stopping due to slow accrual and new treatments) were included from 02/2002 to 02/2006 (205 in each arm). Median follow-up was 25 months. The median number (range) of cycles (28 days) in first line (L1) was respectively 5 (1–24) and 6 (1–24) in the arms A and B (p=0.01), and for L2 (152 and 144 pts in the arms A/B): 5 (1–17) and 3 (1–33) (NS). In the arms A and B, 74% and 70% of pts had L2. L1 was stopped for toxicity for 1% and 16% of the pts in arms A and B (p<0.0001); L2 respectively for 15% and 2% pts (p<0.0001). The percentages of pts presenting at least a grade 3–4 hematologic toxicity (mainly neutropenia) by arm were: 6% versus 37% (p<0.0001) for L1 and 30% versus 27% (NS) for L2; grade 3–4 non hematological toxicity (grade 2–4 neurotoxicity): 26% (1%) versus 56% (64%)(p<0.0001; p<0.0001) for L1 and 54% (60%) versus 46% (40%) of the pts for L2 (NS; p<0.01). No toxic death was observed in the arm A against 5 in the arm B: 3 in L1 and 2 in L2. Overall survival medians were 17 and 16 months in arms A/B (logrank p=0.64) (preliminary results, 291 observed deaths). Conclusions: This trial does not show any substantial difference in treatment duration and overall survival between both arms and shows a more important toxicity in the arm with first line combined chemotherapy. No significant financial relationships to disclose.

Purpose The aim was to investigate whether germline polymorphisms within candidate genes known or suspected to be involved in fluorouracil (FU), oxaliplatin, and irinotecan pathways were associated with toxicity and clinical outcome in patients with metastatic colorectal cancer (mCRC). Patients and Methods Blood samples from 349 patients included in the Fédération Francophone de Cancérologie Digestive 2000-05 randomized trial, which compared FU plus leucovorin (LV5FU2) followed by FU, leucovorin, and oxaliplatin (FOLFOX) followed by FU, leucovorin, and irinotecan (FOLFIRI; sequential arm) with FOLFOX followed by FOLFIRI (combination arm) in terms of progression-free survival (PFS) and overall survival, were collected. Twenty polymorphisms within the DPD, TS, MTHFR, ERCC1, ERCC2, GSTP1, GSTM1, GSTT1, and UGT1A1 genes were genotyped. Results The ERCC2-K751QC allele was independently associated with an increased risk of FOLFOX-induced grade 3 or 4 hematologic toxicity (P = .01). In the sequential arm, TS-5′UTR3RG and GSTT1 alleles were independently associated with response to LV5FU2 (P = .009) and FOLFOX (P = .01), respectively. The effect of oxaliplatin on tumor response increased with the number of MTHFR-1298C alleles (test for trend, P = .008). The PFS benefit from first-line FOLFOX was restricted to patients with 2R/2R (hazard ratio [HR] = 0.39; 95% CI, 0.23 to 0.68) or 2R/3R (HR = 0.59; 95% CI, 0.42 to 0.82) TS-5′UTR genotypes, respectively. Conversely, patients with the TS-5′UTR 3R/3R genotype did not seem to benefit from the adjunction of oxaliplatin (HR = 0.96; 95% CI, 0.66 to 1.40; trend between the three HRs, P = .006). Conclusion A pharmacogenetic approach may be a useful strategy for personalizing and optimizing chemotherapy in mCRC patients and deserves confirmation in additional prospective studies.

588 Background: Bevacizumab (BV) is a recombinant, humanized monoclonal antibody against vascular endothelial growth factor. Used in combination with chemotherapy, BV has been shown to improve survival in both first- and second-line treatment for metastatic colorectal cancer (mCRC). However, it was reported that addition of BV to FOLFOX conferred only little survival benefit (Saltz et al. JCO2008). The aim of this study was to assess the efficacy of addition of BV to FOLFOX in first-line treatment for patients with mCRC. Methods: Bevacizumab was approved for mCRC in July 2007 in Japan. This study was conducted at a single institution and comprised 217 consecutive patients receiving first-line treatment for mCRC between 2005 and 2009. The primary objective was to compare survival benefit in patients treated with FOLFOX4 (FF) between 2005 and 2007 with that in patients receiving FOLFOX4+BV 5 mg/kg (FF+BV) between 2007 and 2009. Results: Total number of patients in the FF and FF+BV groups was 132 and 85, respectively. Characteristics of patients were as follows (FF vs. FF+B): median age, 62 yrs (range 28-76 yrs) vs. 60 yrs (range16-74 yrs); ECOG PS0, 98.8% vs. 81.8%; and median follow-up time, 20.8 months vs. 24.4 months. Median progression-free survival (PFS) in the FF and FF+BV groups was 10 months (95% CI, 8.7-11.3) and 17 months (95% CI, 10.2-14.1), while median overall survival (OS) was 21 months (95% CI, 17.9-24.1) and not reached, respectively. Response rate was 46% (95% CI, 37- 54) in FF, and 62% (95% CI, 51-73) in FF+BV. Addition of BV to FOLFOX4 significantly improved PFS (p=0.002) and OS (p<0.001). Conclusions: The additive effect of BV for first-line FOLFOX was reconfirmed. These data indicate potential survival benefits from the addition of BV to FOLFOX in first-line treatment of mCRC. In addition, PFS may be a sensitive indicator of outcome prior to post-treatment. No significant financial relationships to disclose.

556 Background: Liver dysfunction is one of the irritating adverse effects in chemotherapy for colorectal cancer. Polymorphisms of UGTIA1, which is related to metabolism of CPT-11 in the liver, cause severe adverse events. In addition, long-term induction of CPT-11 may involve steatohepatitis. Thus, it is critical to surrogate liver dysfunction in chemotherapy including CPT-11. In this current study, we evaluated whether NAHLD fibrosis score (NFS) which is liver fibrosis marker of nonalcoholic steatohepatitis, is feasible for predicting the effects and adverse events of chemotherapy including CPT-11 for colorectal cancer. Methods: From January 2007 to May 2013, of 118 patients who were diagnosed with unresectable advanced/recurrent colorectal cancer in our hospital, we retrospectively analyzed 89 patients who underwent first line chemotherapy including CPT-11. We statistically analyzed the value of the pretreatment NFS on response rate (RR), progression-free survival (PFS), and hematologic or non-hematologic toxicity of chemotherapy including CPT-11. Results: The median NFS was -1.302 (range=-5.158 to 2.62). Multivariate analysis revealed that NFS was an independent negative predictive marker for RR (coef -0.373 (-0.712 to -0.035), p = 0.031), although no contribution of NFS was observed to PFS (coef 0.958(0.786|1.168), p=0.672). In terms of the adverse events, high value of NFS is an independent risk factor in hematological toxicity (coef 0.93 (0.20 to 1.65), p = 0.012), while not in non-hematological toxicity (coef 0.198 (-0.218|0.613), p=0.351). Conclusions: The pretreatment NFS might be a feasible for predicting response and hematological toxicity in first line chemotherapy including CPT-11 against colorectal cancer.

PurposeTo evaluate whether capecitabine plus oxaliplatin (XELOX) is noninferior to fluorouracil. folinic acid, and oxaliplatin (FOLFOX-4) as first-line therapy in metastatic colorectal cancer (MCRC).Patients and MethodsThe initial design of this trial was a randomized, two-arm, noninferiority, phase III comparison of XELOX versus FOLFOX-4. After patient accrual had begun, the trial design was amended in 2003 after bevacizumab phase III data became available. The resulting 2 × 2 factorial design randomly assigned patients to XELOX versus FOLFOX-4, and then to also receive either bevacizumab or placebo. We report here the results of the analysis of the XELOX versus FOLFOX-4 arms. The analysis of bevacizumab versus placebo with oxaliplatin-based chemotherapy is reported separately. The prespecified primary end point for the noninferiority analysis was progression-free survival.ResultsThe intent-to-treat population comprised 634 patients from the original two-arm portion of the study, plus an additional 1,400 patients after the start of the amended 2 × 2 design, for a total of 2,034 patients. The median PFS was 8.0 months in the pooled XELOX-containing arms versus 8.5 months in the FOLFOX-4–containing arms (hazard ratio [HR], 1.04; 97.5% CI, 0.93 to 1.16). The median overall survival was 19.8 months with XELOX versus 19.6 months with FOLFOX-4 (HR, 0.99; 97.5% CI, 0.88 to 1.12). FOLFOX-4 was associated with more grade 3/4 neutropenia/granulocytopenia and febrile neutropenia than XELOX, and XELOX with more grade 3 diarrhea and grade 3 hand-foot syndrome than FOLFOX-4.ConclusionXELOX is noninferior to FOLFOX-4 as a first-line treatment for MCRC, and may be considered as a routine treatment option for appropriate patients.

687 Background: XELOX (capecitabine/L-OHP) therapy that includes orally administered fluoropyrimidine instead of infusional fluorouracil (5-FU) was approved for metastatic colorectal cancer (mCRC) in Sep 2009 in Japan. A pivotal trial (NO16966 study) demonstrated the non-inferiority of XELOX to FOLFOX (5-FU/L-OHP/LV) and the superiority of those L-OHP-based regimens plus bevacizumab (BV) to those without in the first-line treatment of mCRC. We evaluated the safety and efficacy of XELO+BV compared with FOLFOX4 or mFOLFOX6 plus BV in the first-line treatment for mCRC patients at a single institute. Methods: Between Jun 2007 and Nov 2008, 85 patients received FOLFOX4+BV (FF4 arm), between Dec 2008 and Sep 2009, 40 patients received mFOLFOX6+BV (FF6 arm), and between Oct 2009 and Sep 2010, 60 patients received XELOX+BV (XELOX arm). The best overall responses were evaluated using RECIST 1.0 during chemotherapeutic treatment, and adverse events were graded according to CTCAE ver.3.0. Progression-free survival (PFS) was estimated by Kaplan-Meier methods. Results: Characteristics of patients of FF4 arm, FF6 arm, and XELOX arm were below: median age, 60 yr vs. 62 yr vs. 60.5 yr; gender (male), 48.2 % vs. 62.5 % vs. 58.3%. The overall response rates (CR+PR) were 61.1 %, 72.5 %, and 75 % (95% CI; 50.6-71.8%, 58.0-87.0%, and 63.7-86.3%). Median PFS were 17.0 months, 15.5 months, and 14.4 months, respectively (cut-off: Aug 31, 2011). There were no statistical significances not only between FF4 arm and FF6 arm (log-rank; p=0.641), but also between XELOX arm and FF4+FF6 (FOLFOX) arm (log-rank; p=0.138). FOLFOX arm was associated with higher incidence of grade 3/4 neutropenia than XELOX arm. Grade3 diarrhea and hand-foot syndrome (HFS) were more frequent in XELOX arm. Conclusions: This study suggests that XELOX arm was equal to FOLFOX arm, regardless of regimen, in tumor response and PFS. Further follow-up is necessary to confirm the benefit on survival.

This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of bevacizumab in combination with fluoropyrimidine-based chemotherapy for the first-line treatment of metastatic colorectal cancer based on the manufacturer’s submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. Evidence was available in the form of one phase III, multicentre, multinational, randomised, open-label study (NO16966 trial). This two-arm study was originally designed to demonstrate the non-inferiority of oral capecitabine plus oxaliplatin (XELOX) compared with 5-fluorouracil plus folinic acid plus oxaliplatin (FOLFOX)-4 in adult patients with histologically confirmed metastatic colorectal cancer who had not previously been treated. Following randomisation of 634 patients, the open-label study was amended to include a 2 × 2 factorial randomised (partially blinded for bevacizumab) phase III trial with the coprimary objective of demonstrating superiority of bevacizumab in combination with chemotherapy compared with chemotherapy alone. Measured outcomes included overall survival, progression-free survival, response rate, adverse effects of treatment and health-related quality of life. The manufacturer’s primary pooled analysis of superiority (using the intention-to-treat population) showed that after a median follow-up of 28 months, the addition of bevacizumab to chemotherapy significantly improved progression-free survival and overall survival compared with chemotherapy alone in adult patients with histologically confirmed metastatic colorectal cancer who were not previously treated [median progression-free survival 9.4 vs 7.7 months (absolute difference 1.7 months); hazard ratio (HR) 0.79, 97.5% confidence interval (CI) 0.72 to 0.87; p = 0.0001; median overall survival 21.2 vs 18.9 months (absolute difference 2.3 months); HR 0.83, 97.5% CI 0.74 to 0.93; p = 0.0019]. The NO16966 trial was of reasonable methodological quality and demonstrated a significant improvement in both progression-free survival and overall survival when bevacizumab was added to XELOX or FOLFOX. However, the size of the actual treatment effect of bevacizumab is uncertain. The ERG believed that the modelling structure employed was appropriate, but highlighted several key issues and areas of uncertainty. At the time of writing, NICE was yet to issue the guidance for this appraisal.

3593 Background: The FIRIS study (Muro K et al. Lancet Oncol 2010;11:853–860) previously demonstrated the non-inferiority of Irinotecan plus S-1(IRIS) to FOLFIRI for metastatic colorectal cancer(mCRC), with progression-free survival (PFS) as the primary endpoint. We previously reported that IRIS plus bevacizumab(IRIS/bev) is very effective as first-line treatment (Komatsu Y et al. ESMO 2010). We now report the updated results of this study. Methods: Eligible patients had to have mCRC with a confirmed diagnosis of adenocarcinoma, an age of >20 years, ECOG performance status (PS) of 0-1, and no history of prior chemotherapy. S-1 40-60 mg twice daily p.o. was given on days 1-14 and irinotecan 100 mg/m2 and bevacizumab 5 mg/kg i.v. were given on days 1 and 15 of a 28-day cycle. The primary endpoint was safety. The secondary endpoints included overall response (OR), progression-free survival (PFS), and overall survival (OS). Results: The target number of 53 patients was enrolled as of March 2009. The results are reported for 52 patients with evaluable lesions. The clinical characteristics of the patients were as follows. The median age was 63.5 years (range, 48 to 82). The male:female ratio was 3:2. The performance status on the Eastern Cooperative Oncology Group scale was 0. In January 2012, on safety analysis, the incidence of grade 3 or 4 neutropenia was 27%. The incidences of other grade 3 or 4 adverse reactions were as follows: diarrhea, 17%; anorexia, 4%; stomatitis, 2%; hypertension, 21%; and gastrointestinal perforation, 0%. The overall response rate was 63.5%. Three patients had complete response. Thirty patients had partial response, 16 had stable disease, none had progressive disease, and 3 were not evaluable. Median progression-free survival was 17.0 months and median survival time was 39.6 months. Conclusions: IRIS/Bev is a remarkably active and generally well-tolerated first-line treatment for patients with mCRC. Randomized control trial comparing this regimen with oxaliplatin containing regimen(XELOX or mFOLFOX6 plus bevacizumab) is being planned.

610 Background: In our previous report, addition of bevacizumab (BV) to the FOLFOX4 regimen appeared to significantly improve response rate, progression-free survival and overall survival in first-line treatment for patients with metastatic colorectal cancer (mCRC) (Suenaga M, et al. ASCO-GI 2011 [abstr 588]). Update results met median overall survival, and statistical analysis of survival was performed. Methods: An observational cohort study was carried out on all eligible patients scheduled to receive FOLFOX4 (n = 128) or FOLFOX4+BV (n = 85) between 2005 and 2007, 2007 and 2009, with a median follow-up time of 20.4 months vs. 30.2 months, respectively. Predefined efficacy endpoints were treatment characteristics, response rates, progression-free survival, and overall survival in the periods of time observed. Results: Median progression-free survival was 9.9 months (95% CI, 8.4-11.4) in the FOLFOX4- and 17 months (95% CI, 11.8-22.3) in the FOLFOX4+BV-treated patients (p=0.002). Median overall survival times were 20.5 months (95% CI, 16.9-24) and 38.8 months (95% CI, 32.9-44.8) in the two groups, respectively (p<0.001). In the ECOG PS 0 population, progression-free survival in the FOLFOX4 and FOLFOX4+BV groups was 11 months and 17 months with a hazard ratio of 0.63 (95% CI, 0.44-0.89) in favour of FOLFOX4+BV, similarly in OS with a hazard ratio of 0.53 (95% CI, 0.36-0.77). Subgroup population received 5-FU plus leucovorin (FL) as maintenance during oxaliplatin discontinuation due to adverse events had longer PFS or OS in both groups, though no significance. PFS were 14.7 and 21.6 months, and OS were 29 and 45.9 months, respectively. Secondary resection was performed more in FOLFOX4+BV (11.8%) than FOLFOX4 (3.9%) patients. Conclusions: These data indicate potential survival benefits from the addition of BV to the FOLFOX4 regimen as first-line treatment for mCRC. Maintenance using FL after discontinuation of oxaliplatin due to adverse events appeared to be an essential factor for better survival.

Purpose Progression-free survival (PFS) has previously been established as a surrogate for overall survival (OS) for first-line metastatic colorectal cancer (mCRC). Because mCRC treatment has advanced in the last decade with extended OS, this surrogacy requires re-examination. Methods Individual patient data from 16,762 patients were available from 22 first-line mCRC studies conducted from 1997 to 2006; 12 of those studies tested antiangiogenic and/or anti–epidermal growth factor receptor agents. The relationship between PFS (first event of progression or death) and OS was evaluated by using R2 statistics (the closer the value is to 1, the stronger the correlation) from weighted least squares regression of trial-specific hazard ratios estimated by using Cox and Copula models. Results Forty-four percent of patients received a regimen that included biologic agents. Median first-line PFS was 8.3 months, and median OS was 18.2 months. The correlation between PFS and OS was modest (R2, 0.45 to 0.69). Analyses limited to trials that tested treatments with biologic agents, nonstrategy trials, or superiority trials did not improve surrogacy. Conclusion In modern mCRC trials, in which survival after the first progression exceeds time to first progression, a positive but modest correlation was observed between OS and PFS at both the patient and trial levels. This finding demonstrates the substantial variability in OS introduced by the number of lines of therapy and types of effective subsequent treatments and the associated challenge to the use of OS as an end point to assess the benefit attributable to a single line of therapy. PFS remains an appropriate primary end point for first-line mCRC trials to detect the direct treatment effect of new agents.

AbstractWe tested the prognostic relevance of metabolic parameters and their relative changes in patients with metastatic colorectal cancer (mCRC) treated with monoclonal antibody and chemotherapy. SUVmax (standardized uptake volume), SAM (standardized added metabolic activity) and TLG (total lesion glycolysis) are assessed with 18F-fluorodeoxyglucosepositron emission tomography and computed tomography (FDG-PET/CT) to evaluate total metabolic activity of malignant processes. Our purpose was to investigate the change of glucose metabolism in relation to PFS (progression free survival) and OS (overall survival). Fifty-three patients with mCRC with at least one measurable liver metastasis were included in this prospective, multi-center, early exploratory study. All patients were treated with first-line chemotherapy and targeted therapy. Metabolic parameters, like SUVmax, SAM, normalized SAM (NSAM) and TLG were assessed by FDG-PET/CT, carried out at baseline (scan-1) and after two therapeutic cycle (scan-2). Our results suggested neither SUVmax nor TLG have such prognostic value as NSAM in liver metastases of colorectal cancer. The parameters after the two cycles of chemotherapy proved to be better predictors of the clinical outcome. NSAM after two cycles of treatment has a statistically significant predictive value on OS, while SAM was predictive to the PFS. The follow up normalized SAM after 2 cycles of first line oncotherapy was demonstrated to be useful as prognostic biomarkers for OS in metastatic colorectal cancer. We should introduce this measurement in metastatic colorectal cancer if there is at least one metastasis in the liver.
