564 Background: XELOX plus bevacizumab (BEV) is an established first-line therapy for metastatic colorectal cancer (mCRC). However, the cumulative neurotoxicity of oxaliplatin often requires therapy to be discontinued while the patient is still responding. The aim of this study was to evaluate efficacy and safety of XELOX plus BEV with oxaliplatin stop and go strategy. Methods: Fifty four patients with unresectable mCRC were enrolled as first-line treatment. They were treated with four cycles of XELOX plus BEV, followed by maintenance therapy with capecitabine (Cape) plus BEV. Reintroduction of oxaliplatin was scheduled after eight cycles of Cape plus BEV or upon tumor progression. The primary endpoint was progression free survival (PFS). Results: Forty nine patients (90%) achieved to the maintenance therapy and thirty one patients (59%) were reintroducted oxaliplatin. The response rates and disease control rates were 57% and 96% in the initial XELOX plus BEV, 6.1% and 73% in Cape plus BEV maintenance therapy. Median PFS in initial XELOX plus BEV was 11.0 months (95%CI: 7.8-14.1). One year survival rate was 86%. Conclusions: XELOX plus BEV was feasible as a first line treatment with mCRC. The most cases achieved disease control during Cape plus BEV maintenance therapy. Clinical trial information: UMIN000006478.

Results: Forty nine patients (90%) achieved to the maintenance therapy and thirty two patients (59%) were reintroduced oxaliplatin. After a median follow-up time of 24.2 months, median PFS was 13.4 months (95%CI: 11.7-15.1), median duration of disease control was 13.8 months (95%CI: 11.6-16.0) and median overall survival was 29.0 months (95%CI: 23.1-34.9). The response rate and disease control rate were 57.4% and 96.3% in the initial XELOX plus BEV therapy, 6.1% and 73.5% in Cape plus BEV maintenance therapy, and 0% and 72.4% in reintroduced XELOX plus BEV therapy. The incidence of neuropathy was 38% in initial therapy, 33% in maintenance therapy and 43% in reintroduced therapy. Conclusions: XELOX plus bevacizumab therapy with oxaliplatin stop-and-go strategy was feasible to maintain long disease control without increasing severe neurotoxicity in first-line treatment for mCRC.

569 Background: In metastatic colorectal cancer (mCRC), a combination of leucovorin and fluorouracil with oxaliplatin (FOLFOX) is one of the standard first-line regimen. The cumulative neurotoxicity of oxaliplatin often requires therapy to be stopped in patients who are still responding. The aim of this study was to evaluate modified FOLFOX6 (mFOLFOX6) with the intermittent oxaliplatin treatment and maintenance therapy with S-1, oral fluoropyrimidine derivative, in the first-line treatment of mCRC. Methods: Thirty patients with untreated mCRC were treated with six cycles of mFOLFOX6 (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, 5-fluorouracil bolus 400 mg/m2 and 5-fluorouracil continuous 2400 mg/m2, every 2 weeks) followed by maintenance therapy with oral S-1 (S-1 80- 120mg/body days 1-28, every 6 weeks). Reintroduction of mFOLFOX6 was scheduled after four cycles of S-1 or tumor progression. The primary study end point was duration of disease control (DDC). Results: Twenty of the 30 patients (66.7%) who achieved responses or stabilizations received S-1 maintenance therapy. mFOLFOX6 was reintroduced in thirteen patients (43.0%). Median DDC was 9.3 months. Median progression-free survival (PFS) was 7.9 months. Overall response rates and disease control rates were 40.0% and 86.6% for the initial mFOLFOX6, 25.0% and 55.0% for S-1 maintenance therapy and 23.1% and 76.9% for mFOLFOX6 reintroduction. Twenty-eight patients (93.3%) had peripheral neuropathy during treatment, but grade 3 neurotoxicity was observed in only 1 patient (3.3%). Conclusions: The planned oxaliplatin stop-and-go strategy with oral S-1 maintenance therapy was feasible first-line treatment for Japanese mCRC patients. Further prospective randamized control study is warranted. No significant financial relationships to disclose.

Metastatic colorectal cancer (mCRC) combined with hyperbilirubinemia is typically considered a contraindication to irinotecan-based therapy, a proven first-line treatment of mCRC. Herein, we present 6 consecutive patients with mCRC combined with hyperbilirubinemia who underwent UGT1A1 genotyping before receiving FOLFIRI plus bevacizumab. Dose escalation of irinotecan was performed according to the results of UGT1A1 genotyping in all patients. Improvement in the serum total bilirubin level to a normal range was noted in all 6 patients. Disease control was 100%. The median progression-free survival was 7.5 months and the median overall survival was 8.5 months. FOLFIRI plus bevacizumab as a first-line chemotherapy may achieve effective disease control and be safe in patients with mCRC and hyperbilirubinemia based on UGT1A1 genotyping. More prospective clinical studies are necessary to evaluate the clinical benefits and safety of this treatment approach.

PurposeThis phase III study compared the safety and efficacy of the following three different irinotecan-containing regimens in the first-line treatment of metastatic colorectal cancer: irinotecan plus infusional fluorouracil (FU)/leucovorin (LV) (FOLFIRI), irinotecan plus bolus FU/LV (mIFL), and irinotecan plus oral capecitabine (CapeIRI).Patients and MethodsA total of 430 previously untreated metastatic colorectal cancer patients were randomly assigned to receive FOLFIRI (n = 144), mIFL (n = 141), or CapeIRI (n = 145). Patients were concurrently randomly assigned to a double-blind treatment with celecoxib or placebo. After a protocol amendment, an additional 117 patients were randomly assigned to either FOLFIRI plus bevacizumab (FOLFIRI+Bev; n = 57) or mILF plus bevacizumab (mIFL+Bev; n = 60), whereas the CapeIRI arm was discontinued. The primary study end point was progression-free survival (PFS), with secondary end points of overall survival (OS), response rate, and toxicity.ResultsMedian PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (P = .004 for the comparison with FOLFIRI), and 5.8 months for CapeIRI (P = .015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL (P = .09), and 18.9 months for CapeIRI (P = .27). CapeIRI was associated with higher rates of severe vomiting, diarrhea, and dehydration. After the amendment to add bevacizumab, the median survival time has not yet been reached for FOLFIRI+Bev and was 19.2 months for mIFL+Bev (P = .007). FOLFIRI+Bev was associated with a higher rate of ≥ grade 3 hypertension than mIFL+Bev.ConclusionFOLFIRI and FOLFIRI+Bev offered superior activity to their comparators and were comparably safe. An infusional schedule of FU should be the preferred irinotecan-based regimen in first-line metastatic colorectal cancer.

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.

491 Background: Infusional fluorouracil/leucovorin plus irinotecan-based regimen (FOLFIRI) with bevacizumab has been widely used as first-line treatment for patients with metastatic colorectal cancer (mCRC). We prospectively analyzed the influence of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) genotyping for irinotecan dose escalation in mCRC patients treated with combination of FOLFIRI and bevacizumab as the first-line setting. Methods: A total of 65 mCRC patients undergoing first-line treatment with FOLFIRI combined with bevacizumab were analyzed. Genotypes were performed by analyzing the sequence of TATA box of UGT1A1 of genomic DNA from the patients. Genotype and clinical parameters were compared by univariate analysis. The irinotecan dose is escalating form 180 mg/m2 to 260 mg/m2 in UGT1A1 6/6 or 6/7, and from 120 mg/m2 to 210 mg/m2 in UGT1A17/7. Results: The response rate was observed in 44 of 60 UGT1A1 6/6 or 6/7 (73.3%) in comparison to 1 of 5 UGT1A1 7/7 (20%) patients (p=0.013). The grade III-IV adverse events (AE) was observed in 4 of 60 UGT1A1 6/6 or 6/7 (6.7%) in comparison to 3 of 5 UGT1A1 7/7 (60%) patients (p<0.001), but it was not different between age of ≥ 70 and < 70 (p=0.559). Fifteen of 60 (20%) patients with UGT1A1 6/6 or 6/7 could be performed with liver or lung metastaectomy in comparison to none of 5 patients with UGT1A1 7/7. In addition, the disease control rate was significantly higher in irinotecan dose of ≥ 210 mg/m2 than irinotecan dose of < 210 mg/m2(p=0.015). Conclusions: UGT1A1 promoter polymorphism was found to be predictive of toxicity and efficacy in mCRC patients with first-line treatment of FOLFIRI combined with bevacizumab. The higher dose of irinotecan (≥ 210 mg/m2) may achieve a better disease control rate but do not increase the incidence of GR III-IV AE in mCRC patients of age ≥ 70 years.

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.
