Abstract Purpose Adjuvant FOLFOX therapy is an established standard-of-care for resected colon cancer. Peripheral sensory neuropathy (PSN) is regarded as the major toxicity issue related to FOLFOX therapy. There have been a few reports on the recovery status from PSN thereafter. JOIN trial investigated the tolerability and efficacy of adjuvant modified FOLFOX6 (mFOLFOX6) in Japanese patients with stage II/III colon cancer. Methods Twelve cycles of mFOLFOX6 were given to patients with stage II/III curatively resected colon cancer. Treatment outcomes, including disease-free survival (DFS), relapse-free survival (RFS), overall survival (OS), and recovery status of PSN during 3-year follow-up, were investigated. Results Of the 882 patients enrolled from 2010 to 2012, 864 were eligible for the efficacy analyses. Three-year DFS, RFS, and OS were favorable in 92.1, 92.8, and 97.4% of stage II patients; 76.4, 77.9, and 93.8% of stage IIIA/B; and 61.6, 62.7, and 85.9% of stage IIIC, respectively. The cumulative incidence of PSN during treatment was 47.8% in grade 1 (G1), 30.3% in G2, and 5.8% in G3. For those with G3 PSN during treatment, there was gradual recovery in 1.1% of patients at 12 months after enrollment, 0.5% at 24 months, and 0.2% at 36 months. However, G1 or G2 residual PSN after 3 years was observed in 21.0% (18.7%, G1; 2.3%, G2). Conclusions Adjuvant mFOLFOX6 therapy was effective and well tolerated in patients with stage II/III colon cancer. Most patients recovered from G3 PSN related to oxaliplatin, but approximately 20% of patients had G1 or G2 PSN at 3-year follow-up.

703 Background: The JOIN Trial investigated safety and efficacy of modified FOLFOX6 (mFOLFOX6) in Japanese patients (pts) with stage II/III colon cancer. In the initial safety report, incidence of ≥ grade 3 (G3) peripheral sensory neuropathy (PSN) was 5.8% during treatment. Methods: Twelve cycles of mFOLFOX6 were given to pts with the following criteria: stage II/III curatively resected colon cancer; ECOG Performance Status (PS) of 0–1; age, ≥ 20 years; and adequate organ function. We report the treatment outcome results, including disease-free survival (DFS), relapse-free survival (RFS), overall survival (OS), and recovery from PSN during 3-year follow-up. Results: From November 2010 to March 2012, 882 pts were enrolled. In the efficacy group (N = 864; median follow-up, 3 years), pt characteristics were as follows: median age, 64 years; male, 53.8%; PS 0, 93.8%; stage II/IIIA/IIIB/IIIC (TNM), 18.5/7.3/52.5/21.6%; and lymph nodes examined, < 12/ > 12/unknown: 17.2/82.5/0.2%, respectively. Three-year DFS, RFS, and OS were 76.1, 77.3, and 92.7%, respectively. Favorable 3-year DFS, RFS, and OS were 92.1, 92.8, and 97.4% in stage II patients; 76.4, 77.9, and 93.8% in stage IIIA/B; and 61.6, 62.7, and 85.9% in stage IIIC, respectively. The main recurrent sites were liver (7.6%), lung (7.3%), and lymph nodes (5.2%). In multivariate Cox regression analysis, tumor histology, venous invasion, and lymph node metastatic ratio were statistically significant prognostic factors for DFS, RFS, and OS. Cumulative incidence of PSN during treatment was 47.8% in G1, 30.3% in G2, and 5.8% in G3. For those with G3 PSN during treatment, there was gradual recovery in 1.1% at 12 months after enrollment, 0.5% at 24 months, and 0.2% at 36 months. However, G1 and G2 residual PSN after 3 years was observed in 21.0% of pts (18.7%, G1; 2.3%, G2). Conclusions: Efficacy and safety of adjuvant mFOLFOX6 in pts with stage II/III colon cancer can be confirmed. Most pts successfully recovered from G3 PSN related to oxaliplatin, but G1 and G2 PSN was irreversible in one-fifth of pts at the 3-year follow-up. Clinical trial information: UMIN000004443.

4007 Background: The MOSAIC study was designed to evaluate the effects of the FOLFOX4 regimen (5-FU/LV + oxaliplatin) on 3- year disease free survival (DFS) probability in patients with stage II and III colon cancer. Methods: Patients (n=2246) with completely resected stage II (40%) or III (60%) colon cancer were randomly assigned to receive 5-FU/LV (LV5FU2) or FOLFOX4 every 2 weeks for 12 cycles. Results: Results for the primary endpoint of the study (for the overall population, with a median follow-up [FU] of 3 years), showed a significant benefit in DFS for the FOLFOX4-treated patients (78.2% vs 72.9%; HR: 0.77, p=0.002) (André et al, NEJM, 2004). Patients were followed beyond the 3-year cut-off for DFS and overall survival (OS) updates. Final DFS, at 5 years FU, are consistent with earlier results (HR: 0.80, p = 0.003). In addition, at a median FU of 6 years, the study demonstrates a significant benefit in OS for the stage III patients. Summary of OS results (median FU 6 years) Long-term safety update shows no increase in the rate of secondary cancer (5.0% in both treatment arms). Conclusions: These results confirm the benefit of the FOLFOX4 regimen in adjuvant colon cancer patients. [Table: see text] No significant financial relationships to disclose.

PurposeThe National Surgical Adjuvant Breast and Bowel Project trial C-08 was designed to investigate the safety and efficacy of adding bevacizumab to fluorouracil, leucovorin, and oxaliplatin (FOLFOX6) for the adjuvant treatment of patients with stage 2-3 colon cancer. Our report summarizes the primary and secondary end points of disease-free and overall survival, respectively, with 5 years median follow-up time.Patients and MethodsPatients received modified FOLFOX6 once every 2 weeks for a 6-month period (control group) or modified FOLFOX6 for 6 months plus bevacizumab (5 mg/kg) once every 2 weeks for a 12-month period (experimental group). The primary end point of the study was disease-free survival (DFS) and overall survival (OS) was a secondary end point.ResultsOf 2,673 analyzed patients, demographic factors were well-balanced by treatment. With a median follow-up of 5 years, the addition of bevacizumab to mFOLFOX6 did not result in an overall significant increase in DFS (hazard ratio [HR], 0.93; 95% CI, 0.81 to 1.08; P = .35). Exploratory analyses found that the effect of bevacizumab on DFS was different before and after a 1.25-year landmark (time-by-treatment interaction P value <.0001). The secondary end point of OS was no different between the two study arms for all patients (HR, 0.95; 95% CI, 0.79 to 1.13; P = .56) and for those with stage 3 disease (HR, 1.0; 95% CI, 0.83 to 1.21; P = .99).ConclusionBevacizumab for 1 year with modified FOLFOX6 does not significantly prolong DFS or OS in stage 2-3 colon cancer. We observed no evidence of a detrimental effect of exposure to bevacizumab. A transient effect on disease-free survival was observed during bevacizumab exposure in the study's experimental arm.

Purpose Three-year disease-free survival (DFS) was significantly improved in patients who had undergone resection with curative intent for stage II or III colon cancer who received bolus plus continuous-infusion fluorouracil plus leucovorin (LV5FU2) with the addition of oxaliplatin (FOLFOX4). Final results of the study, including 6-year overall survival (OS) and 5-year updated DFS, are reported. Patients and Methods A total of 2,246 patients were randomly assigned to receive LV5FU2 or FOLFOX4 for 6 months. The primary end point was DFS. Secondary end points were OS and safety. Results Five-year DFS rates were 73.3% and 67.4% in the FOLFOX4 and LV5FU2 groups, respectively (hazard ratio [HR] = 0.80; 95% CI, 0.68 to 0.93; P = .003). Six-year OS rates were 78.5% and 76.0% in the FOLFOX4 and LV5FU2 groups, respectively (HR = 0.84; 95% CI, 0.71 to 1.00; P = .046); corresponding 6-year OS rates for patients with stage III disease were 72.9% and 68.7%, respectively (HR = 0.80; 95% CI, 0.65 to 0.97; P = .023). No difference in OS was seen in the stage II population. The incidence of second noncolorectal cancers was 5.5% and 6.1% in the FOLFOX4 and LV5FU2 groups, respectively. Among patients receiving oxaliplatin, the frequency of grade 3 peripheral sensory neuropathy was 1.3% 12 months after treatment and 0.7% at 48 months. Conclusion Adding oxaliplatin to LV5FU2 significantly improved 5-year DFS and 6-year OS in the adjuvant treatment of stage II or III colon cancer and should be considered after surgery for patients with stage III disease.

Purpose The National Surgical Adjuvant Breast and Bowel Project (NSABP) C-07 trial demonstrated that the addition of oxaliplatin to fluorouracil plus leucovorin (FULV) improved disease-free survival (DFS) in patients with stage II or III colon cancer. This analysis is the first publication of overall survival (OS) for the NSABP C-07 study. We updated DFS and examined both end points in clinically relevant patient subsets. Patients and Methods Other studies have identified patients age 70 or older and those with stage II disease as patient subsets in which oxaliplatin may not be effective. We investigated toxicity as a driver of divergent outcomes in these subsets. Results In all, 2,409 eligible patients with follow-up were randomly assigned to either FULV (FU 500 mg/m2 by intravenous [IV] bolus weekly for 6 weeks; leucovorin 500 mg/m2 IV weekly for 6 weeks of each 8-week cycle for three cycles) or FLOX (FULV plus oxaliplatin 85 mg/m2 IV on days 1, 15, and 29 of each cycle). With 8 years median follow-up, OS was similar between treatment groups (hazard ratio [HR], 0.88; 95% CI, 0.75 to 1.02; P = .08). FLOX remained superior for DFS (HR, 0.82; 95% CI, 0.72 to 0.93; P = .002). The effect of oxaliplatin on OS did not differ by stage of disease (interaction P = .38 for OS; interaction P = 0.37 for DFS) but did vary by age for OS (younger than age 70 v 70+ interaction P = .039). There was a similar trend for DFS (interaction P = .073). Oxaliplatin significantly improved OS in patients younger than age 70 (HR, 0.80; 95% CI, 0.68 to 0.95; P = .013), but no positive effect was evident in older patients. Conclusion Overall, the addition of oxaliplatin to FULV has not been proven to extend OS in this trial, but the DFS effect remained strong. Unplanned subset analyses suggest a significant OS effect of oxaliplatin in patients younger than age 70.

3500 Background: The IDEA aimed to investigate whether a 3-month (3M) of oxaliplatin/fluoropyrimidines-based adjuvant chemotherapy (CT) is non-inferior to the 6-month (6M) in 3-year disease free survival (DFS) in stage high risk stage II and in stage III colon cancer (CC). Methods: HORG-IDEA randomized patients between 3M and 6M of CT with FOLFOX4 or CAPOX with primary end point the 3 years DFS (3yDFS). Results: In total 1121 patients, 413 with high risk stage and 708 with stage IIICC, were randomized between May 2009 and October 2015. The median follow-up was 67 (38-126) months. There were 79 DFS events (43 in 3M and 38 in 6M arm) in high risk stage II patients leading to 3yDFS rate of 82.7 and 83.4% for 3M and 6M, respectively (HR: 1.05; 95%CI: 0.68-1.63, p = 0.829). Similarly, 214 DFS events (161 in 3M and 153 in 6M arm) has been recorded in stage III patients, leading to a 3yDFS rate of 72.9% in the 3M vs. 74.1% in the 6M (HR = 1.06; 95%CI: 0.81–1.42, p = 0.622). For high risk stage II patients receiving FOLFOX4, 3yDFS rate was 76.7% in the 3M vs.79.3% in the 6M (HR = 1.21; 95%CI: 0.54–2.70 p = 0.641). For high risk stage II patients receiving CAPOX 3-year DFS rate was 85.4% in the 3M vs. 83.8% in the 6M (HR = 0.99; 95%CI: 0.59–1.67 p = 0.968). For stage III CC patients receiving mFOLFOX6, 3-year DFS rate was 71.5% in the 3M vs.77.3% in the 6M (HR = 1.18; 95%CI: 0.74–1.86 p = 0.479). For stage III CC patients receiving CAPOX 3-year DFS rate was 74.5% in the 3M vs. 74.7% in the 6M (HR = 0.99; 95%CI: 0.70–1.44 p = 0.991). Conclusions: The results of the HORG-IDEA study are in line with those of the global IDEA project, indicating that 3yDFS is depended on the administered adjuvant regimen, and the choice of regimen and duration should be personalized. Clinical trial information: NCT01308086.

Purpose: This randomized, 2 × 2 factorial study compared a semimonthly (LVFU2) with a monthly (FULV) regimen of fluorouracil and leucovorin and 24 versus 36 weeks of each regimen as adjuvant treatment of patients with stage II (Dukes’ B2) and III (Dukes’ C) colon cancer. Patients and Methods: LVFU2 was administered semi-monthly for 2 consecutive days as dl- or l-leucovorin (200 or 100 mg/m2, respectively) as a 2-hour infusion, followed by a 400 mg/m2 FU bolus and 600 mg/m2 of FU as a 22-hour continuous infusion. FULV was administered monthly for 5 consecutive days as a 15-minute infusion of dl- or l-leucovorin, followed by 400 mg/m2 of FU as a 15-minute infusion. Results: A total of 905 patients were randomly assigned. The median follow-up was 41 months. Disease-free survival was similar between the LVFU2 and FULV groups (127 v 124 events; hazard ratio [HR] = 1.04; P = .74) and between 24 and 36 weeks of therapy (128 v 123 events; HR = 0.94; P = .63). Analysis of overall survival showed a slight excess in the number of deaths in LVFU2 compared with FULV (73 v 59), but this difference was not statistically significant (HR = 1.26; 95% confidence interval, 0.90 to 1.78; P = .18). The most commonly observed grade 3 to 4 toxicities were neutropenia, diarrhea, and mucositis. Toxicities were significantly lower in the LVFU2 group (all toxicities, P < .001). Conclusion: Our data confirm that LVFU2 is less toxic than FULV. At a median follow-up of 41 months, no statistically significant difference could be detected in disease-free or overall survival between the treatment groups or treatment durations.

Abstract Background Disease-free survival with a 3-year median follow-up (3-year DFS) was validated as a surrogate for overall survival with a 5-year median follow-up (5-year OS) in adjuvant chemotherapy colon cancer (CC) trials. Recent data show further improvements in OS and survival after recurrence, in patients who received adjuvant FOLFOX. Hence, re-evaluation of the association between DFS and OS and determination of the optimal follow-up duration of OS to aid its utility in future adjuvant trials are needed. Methods Individual patient data from nine randomized studies conducted between 1998 and 2009 were included; three trials tested biologics. Trial-level surrogacy examining the correlation of treatment effect estimates of 3-year DFS with 5 to 6.5-year OS was evaluated using both linear regression (R2WLS) and Copula bivariate (R2Copula) models and reported with 95% confidence intervals (CIs). For R2, a value closer to 1 indicates a stronger correlation. Results Data from a total of 18,396 patients were analyzed (median age = 59 years; 54.0% male), with 54.1% having low-risk tumors (pT1-3 & pN1), 31.6% KRAS mutated, 12.3% BRAF mutated, and 12.4% microsatellite instability high/deficient mismatch repair tumors. Trial level correlation between 3-year DFS and 5-year OS remained strong (R2 =0.82, 95% CI = 0.67 to 0.98; R2 =0.92, 95% CI = 0.83 to 1.00) and increased as the median follow-up of OS extended. Analyses limited to trials that tested biologics showed consistent results. Conclusion Three-year DFS remains a validated surrogate endpoint for 5-year OS in adjuvant CC trials. The correlation was likely strengthened with 6 years of follow-up for OS.
