Purpose The National Surgical Adjuvant Breast and Bowel Project C-08 trial was designed to investigate the safety and effectiveness of adding bevacizumab to modified infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) 6 regimen for the adjuvant treatment of patients with stage II or III colon cancer. We present safety information in advance of the planned analysis of efficacy. Patients and Methods Among 2,710 randomly assigned patients, demographic factors were balanced. Patients received modified FOLFOX6 every 2 weeks × 12 or modified FOLFOX6 plus bevacizumab (5 mg/kg every 2 weeks × 26, experimental group). Results Overall rates of grade 4 or 5 toxicities were nearly identical in the FOLFOX6 and FOLFOX6 plus bevacizumab arms (15.2% and 15.0%, respectively). Six-month mortality rates were 0.96% and 0.90% for the control and experimental groups, respectively. Grade 3+ toxicities that occurred more often in the experimental arm versus control arm included hypertension (12% v 1.8%, respectively), wound complications (abdominal incisional hernia or infusion port dehiscence/inflammation; 1.7% v 0.3%, respectively), pain (11.1% v 6.3%, respectively), and proteinuria (2.7% v 0.8%, respectively). Grade 2+ neuropathy was increased in the experimental arm versus the control arm (grade 2, 33% v 29%, respectively; grade 3, 16% v 14%, respectively; and grade 4, < 1% each). In the experimental arm versus control arm, significantly less thrombocytopenia (1.4% v 3.4%, respectively) and fewer allergic reactions (3.1% v 4.7%, respectively) were observed. Advanced age was associated with a significantly greater rate of grade 4 and 5 toxicities regardless of treatment. Conclusion Bevacizumab with modified FOLFOX6 is well tolerated in the surgical adjuvant setting in these patients. No significant increase in GI perforation, hemorrhage, arterial or venous thrombotic events, or death with the addition of bevacizumab to modified FOLFOX6 has been observed. Follow-up for potential delayed adverse effects and efficacy is ongoing.

530 Background: Adjuvant FOLFOX is a widely accepted standard regimen for resected colon cancer. The incidence of grade ≥ 3 peripheral sensory neuropathy (PSN) was 12.4% and 5.7% in Western MOSAIC and Eastern MASCOT (outside Japan) trials, while that of grade ≥ 3 allergic reactions (AR) was 2.9% and 3.1%, respectively. JOIN Trial investigated the tolerability of modified FOLFOX6 (mFOLFOX6) in Japanese patients (UMIN ID: 000004443). Methods: Twelve cycles of mFOLFOX6 were given to patients fitting the following criteria, which were the same as those of MOSAIC: stage II/III resected colon cancer, PS of 0-1, 20 years or older, starting FOLFOX within 7 weeks of surgery, and adequate organ function. The primary endpoint was the incidence of PSN persisting for at least 8 days that interfered with daily activities and that of grade ≥ 3 AR. Target sample size was 800, assuming the expected incidence of grade ≥ 3 PSN and grade ≥ 3 AR would be 12.0% and 3.0%, and the two-sided 95% confidence interval (CI) would not include the corresponding threshold levels (16.5% for PSN and 6.5% for AR) with a 95% probability. Results: From Nov 2010 to Mar 2012, 882 patients were enrolled at 198 institutions. The safety data was analyzed in 828 patients whose data were finalized out of 848 patients received mFOLFOX6, and patient characteristics included: median age of 64 years (21-83); Male/ Female: 444/384; PS 0/1: 776/52; colon/rectosigmoid: 633/195; and stage IIA/IIB/IIC/IIIA/IIIB/IIIC: 96/33/23/61/437/178. The incidence of persistent PSN was 3.3% (95% CI: 2.2%-4.7%), while that of grade ≥ 3 AR was 1.7% (95% CI: 1.0%-2.8%), and the primary endpoint was met. Only grade ≥ 3 neutropenia showed a ≥ 10% incidence (28.7%). The incidence of grade ≥ 3 PSN was 5.8% and interstitial pneumonitis was observed in one case. There was no treatment-related death. The median number of cycles of chemotherapy was 12, and the completion treatment rate was 67.0%. The median total dosage of oxaliplatin (L-OHP) was 811.1 mg/m2. The median relative dose intensity of L-OHP, fluorouracil (FU) bolus and FU infusion were 90.0%, 76.9% and 81.7%, respectively. Conclusions: Adjuvant mFOLFOX6 is tolerable in Japanese patients with colon cancer. Clinical trial information: UMIN000004443.

4053 Background: The aim of our phase III study was to compare the effectiveness and the toxicity profile of 5-Fluorouracil (5- FU) + folinic acid (FA) + irinotecan (CPT-11) as adjuvant chemotherapy for resectable colon cancer (Dukes B2 and C) to that of 5-FU + FA which was considered the standard treatment. Since patients are still on follow-up regarding the primary endpoint, only safety results will be presented. Methods: Eligible patients received either 5-FU (450 mg/m2 bolus) + FA (200 mg/m2, 120 min infusion) + CPT- 11 (80 mg/m2, 90 min infusion) given 4 weeks on, two weeks off for a total of 6 treatment cycles (Arm A) or 5-FU (500 mg/m2 bolus) + FA (200 mg/m2, 120 min infusion) given 6 weeks on, two weeks off for a total of 4 treatment cycles (Arm B). Results: From January 1999 to September 2004, 910 patients (pts) were enrolled in this multi-center phase III trial. Safety data are available for 826 of the 910 pts, (415 in arm A and 411 in arm B). The total number of chemotherapy courses delivered was 8,906 (92%) in arm A and 8,775 (91%) in arm B, with median courses per patient 24 in both groups. Among patients who received treatment as randomized (403 in arm A and 398 in arm B), treatment was completed in 342 pts (82%) in arm A and in 341 pts (83%) in arm B. The number of patients who discontinued the treatment was 61 (15%) in arm A and 57 (14%) in arm B. Hospitalizations because of toxic effects happened in 37 pts (9%) in arm A and in 45 pts (11%) in arm B. Three deaths occurred in both arms. Use of G-CSF was more common in arm A (94 pts, 23%) than in arm B (38 pts, 9.5%) (p< 0.001). Significantly higher grade 3/4 neutropenia was observed in group A (11% in arm A and 3% in arm B, p< 0.001). Severe diarrhea was also frequently reported in both groups. Conclusions: These data show that both regimens have comparable and manageable toxicity profiles as adjuvant treatment in colon cancer. Severe neutropenia was more often seen in arm A. No significant financial relationships to disclose.

Purpose This phase III clinical trial evaluated the impact on disease-free survival (DFS) of adding oxaliplatin to bolus weekly fluorouracil (FU) combined with leucovorin as surgical adjuvant therapy for stage II and III colon cancer. Patients and Methods Patients who had undergone a potentially curative resection were randomly assigned to either FU 500 mg/m2 intravenous (IV) bolus weekly for 6 weeks plus leucovorin 500 mg/m2 IV weekly for 6 weeks during each 8-week cycle for three cycles (FULV), or the same FULV regimen with oxaliplatin 85 mg/m2 IV administered on weeks 1, 3, and 5 of each 8-week cycle for three cycles (FLOX). Results A total of 2,407 patients (96.6%) of the 2,492 patients randomly assigned were eligible. Median follow-up for patients still alive is 42.5 months. The hazard ratio (FLOX v FULV) is 0.80 (95% CI, 0.69 to 0.93), a 20% risk reduction in favor of FLOX (P < .004). The 3- and 4-year disease-free survival (DFS) rates were 71.8% and 67.0% for FULV and 76.1% and 73.2% for FLOX, respectively. Grade 3 neurosensory toxicity was noted in 8.2% of patients receiving FLOX and in 0.7% of those receiving FULV (P < .001). Hospitalization for diarrhea associated with bowel wall thickening occurred in 5.5% of the patients receiving FLOX and in 3.0% of the patients receiving FULV (P < .01). A total of 1.2% of patients died as a result of any cause within 60 days of receiving chemotherapy, with no significant difference between regimens. Conclusion The addition of oxaliplatin to weekly FULV significantly improved DFS in patients with stage II and III colon cancer. FLOX can be recommended as an effective option in clinical practice.

PurposeThis randomized, 2 × 2 factorial study compared a semimonthly regimen (fluorouracil [FU] and leucovorin [LV] semi-monthly is LV5FU2) with a monthly regimen of FU and LV (mFU/LV) as well as 24 weeks versus 36 weeks of each regimen as adjuvant treatment of stage II and III colon cancer.Patients and MethodsLV5FU2 was administered semimonthly for 2 days as racemate (dl) or levogyre (l-; 200 or 100 mg/m2) as a 2-hour infusion, followed by 400 mg/m2FU bolus and a 600-mg/m2FU 22-hour continuous infusion. FU and LV were administered monthly (mFU/LV) for 5 days as dl- or l-LV 15-minute infusion, followed by a 400 mg/m2FU 15-minute infusion. The primary end point was disease-free survival (DFS).ResultsBetween September 1996 and November 1999, 905 patients with stage II (43%) and III (57%) colon cancer were enrolled. The median follow-up was 6 years. There was no statistically significant difference between mFU/LV and LV5FU2 in terms of DFS (150 v 148 events; hazard ratio [HR],1.01; 95% CI, 0.806 to 1.269; P = .94) and overall survival (OS; 104 v 103 events; HR,1.02; 95% CI, 0.77 to 1.34; P = .91). No statistical difference was observed between 24 or 36 weeks of chemotherapy. Median survival from metastatic relapse was 24 months. The survival of patients with metastatic relapse (n = 243) was significantly longer for patients with a longer time from random assignment to relapse (< 1, 1 to 2, ≥ 2 years; log-rank test for trend P, .0497).ConclusionDFS and OS were not statistically different between treatment groups and treatment durations. These data confirm the value of LV5FU2 as control arm in the Multicenter International Study of Oxaliplatin/5FU-LV in the Adjuvant Treatment of Colon Cancer and Pan-European Trials in Adjuvant Colon Cancer studies.

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.
