Background: Maintenance chemotherapeutic regimen with low toxicity is needed for metastatic colorectal cancer. A recent patent has been issued on the spleen-strengthening and detoxification prescription (JPJDF), a traditional Chinese herbal medicinal formula with anti-angiogenesis effect. The clinical effect of JPJDF on the maintenance treatment of advanced colorectal cancer has not been evaluated. Objective: This study aims to evaluate the effectiveness and safety of JPJDF in combination with fluoropyrimidine compared to fluoropyrimidine alone as maintenance therapy for metastatic colorectal cancer. Methods: We applied a prospective, randomized, double-blinded, single center clinical study design. A total of 137 patients with advanced colorectal cancer were recruited. Patients received either Fluoropyrimidine (Flu-treated group, n = 68), or Fluoropyrimidine plus JPJDF (Flu-F-treated group, n = 69) as maintenance treatment after 6-cycle of FOLFOX4 or FOLFORI induction treatment. The primary endpoints were Progression-Free Survival (PFS) and Overall Survival (OS). The secondary endpoints were safety, Performance Status (PS) score and other symptoms. Results: The endpoint of disease progression was observed in 91.7% of patients. The PFS was 5.0 months and 3.0 months in the Flu-F-treated and Flu-treated groups, respectively. The OS was 15.0 months and 9.0 months in the Flu-F-treated and Flu-treated groups, respectively. Some common symptoms, such as hypodynamia, anepithymia, dizziness and tinnitus and shortness of breath, were improved in the Flu-F-treated group. There was no significant difference in the common adverse reactions between the two groups. Conclusion: JPJDF and fluoropyrimidine have synergistic effect in the maintenance treatment of mCRC.

e14552 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 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.

737 Background: Primary tumor sidedness (PTS) could be a predictive maker for treatment efficacy of EGFR inhibitors monoclonal antibodies in patients with wild-type (WT) RAS metastatic colorectal cancer (MCRC), cetuximab having limited efficacy in patients with WT-RAS right-sided tumors. DREAM study demonstrated that adding erlotinib, an oral EGFR tyrosine kinase inhibitor (TKI) to bevacizumab during maintenance therapy improved clinical outcomes (RR, PFS, OS) in patients with MCRC, whatever KRAS status. The aim of this post-hoc analysis is to evaluate the clinical outcomes according to KRAS mutational status and PTS when adding erlotinib to bevacizumab maintenance therapy. Methods: PTS was retrospectively collected in patients from the DREAM phase III trial treated with bevacizumab with or without erlotinib as maintenance therapy for MCRC who have been controlled by induction therapy. The limit for the definition of PTS was splenic flexure, and rectal tumors were considered as left-sided tumors. The primary endpoint was overall survival (OS). Results: Among 452 patients who received maintenance therapy, PTS ascertainment was 84.7% (n = 383) with 265 (71.0%) patients having left-sided primary tumor and 108 (28.9%) having right-sided primary tumors (3 patients had both and tumor location was unknown in 7 patients). Median OS and treatment effect are presented in table 1. Conclusions: The greatest OS benefit of adding erlotinib to bevacizumab maintenance therapy was observed in patients with WT-KRAS and right-sided MCRC, suggesting a clinical impact of the different mechanism of action between EGFR TKI and monoclonal antibodies. Clinical trial information: NCT00265824. [Table: see text]
