3569 Background: Adjuvant capecitabine results in at least equivalent disease-free survival (DFS) to i.v. bolus 5-FU/LV in stage III colon cancer [Twelves et al. 2005]. Early phase III data in 1st-line metastatic colorectal cancer suggest that XELOX is as safe as oxaliplatin + infusional 5-FU ± LV [Sastre et al. 2005; Ducreux et al. 2005]. The XELOXA study compared safety and efficacy of XELOX vs. bolus 5-FU/LV (the standard regimen at study start) as adjuvant therapy for stage III colon cancer. Methods: Pts with resected disease were randomized to receive either XELOX (capecitabine 1000 mg/m2 bid d1–14 + oxaliplatin 130 mg/m2 d1, q3w for 8 cycles) or i.v. bolus 5-FU/LV (Mayo Clinic, LV 20 mg/m2 + 5-FU 425 mg/m2 d1–5, q4w for 6 cycles; or Roswell Park [RP], LV 500 mg/m2 + 5-FU 500 mg/m2 d1, w1–6 in 8w cycles x4). Centers’ preferred 5-FU/LV regimen was selected at study start and used in all pts. Results: 1861/1886 pts randomized between Apr 03 and Oct 04 are evaluable for safety. The rate of related grade 3/4 adverse events (AEs) was 54% for XELOX and 45% for 5-FU/LV ( table ). 60-day all cause mortality was 1.0% in both arms. Treatment-related death rate within 28 days from last dose was 0.7% for XELOX and 0.5% for 5-FU/LV. Conclusions: XELOX causes less myelosuppression and stomatitis but more skin toxicity than 5-FU/LV. The inclusion of oxaliplatin adds neurosensory toxicity. Cross-study comparison of grade 3/4 AEs in the current and MOSAIC trials suggests that XELOX safety is similar to FOLFOX4, with the advantage of an oral fluoropyrimidine-based regimen. Final safety data will be presented at the meeting, and efficacy data will be available in 2007. [Table: see text] [Table: see text]

ObjectiveAdjuvant Chemotherapy Trial of TS-1 for Colon Cancer (ACTS-CC), a randomised phase III trial, demonstrated that adjuvant therapy with S-1 for stage III colon cancer was non-inferior in 3-year disease-free survival (DFS) to that of tegafur-uracil plus leucovorin (UFT/LV). We updated DFS and overall survival (OS) and performed T x N subset analysisMethodsA total of 1518 patients with curatively resected stage III colon cancer were randomly assigned to receive S-1 (80–120  mg/day on days 1–28 every 42 days, four courses) or UFT/LV (UFT: 300–600  mg/day and LV: 75  mg/day on days 1–28 every 35 days, five courses)ResultsThe 5-year DFS rates of the S-1 and UFT/LV group were 70.2 % and 66.9 %, respectively (HR 0.88; 95%  CI 0.74 to 1.06; p=0.177), and non-inferiority of DFS was reconfirmed with a median of 63.5-month follow-up. The similarity of OS was also confirmed (HR 0.92; 95%  CI 0.72 to 1.17; p=0.488); 5-year OS rates of the S-1 and UFT/LV group were 86.0 % and 84.4 %, respectively. No significant interactions were identified between the major baseline characteristics and DFS of the S-1 and UFT/LV groups, except for histological type; S-1 was more favourable in patients with poorly differentiated adenocarcinoma. Patient outcomes were well separated by TNM-substages (IIIA/IIIB/IIIC). With the patients divided into 20 subsets by T and N factors, the DFS and OS rates of T3 and N1 subset, which accounted for 62 % of stage IIIB patients and 44 % of all studied subjects, were significantly better than those of the other subsets in stage IIIB and similar to those of stage IIIA.ConclusionsAdjuvant therapy of S-1 for stage III colon cancer was reconfirmed to be non-inferior in DFS to those of UFT/LV after long follow-up. No difference in OS was also demonstrated. T3N1 patients might be considered separately from other patients included in stage IIIB because of its favourable outcome.Trial registration numberNCT00660894.

PurposeTo report the results of a planned safety analysis from a phase III trial comparing capecitabine plus oxaliplatin (XELOX) with bolus fluorouracil/leucovorin (FU/LV) as adjuvant therapy for stage III colon cancer.Patients and MethodsPatients with stage III colon carcinoma were randomly assigned to receive either XELOX (intravenous oxaliplatin plus oral capecitabine; 3-week cycle for eight cycles) or standard intravenous bolus FU/LV administered as the Mayo Clinic (Mayo; Rochester, MN) or Roswell Park (RP; Buffalo, NY) regimen for a similar length of time. A total of 1,886 patients were randomly assigned.ResultsThe safety population comprised 1,864 patients, of whom 938 received XELOX and 926 received FU/LV. Most treatment-related adverse events (AEs) occurred at similar rates in both treatment arms. However, patients receiving XELOX experienced less all-grade diarrhea, alopecia, and more neurosensory toxicity, vomiting, and hand-foot syndrome than those patients receiving FU/LV. Compared with Mayo, XELOX showed fewer grade 3/4 hematologic AE and more grade 3/4 gastrointestinal AE. Compared with RP, XELOX showed less grade 3/4 gastrointestinal AE and more grade 3/4 hematologic AE. As expected grade 3/4 neurosensory toxicity and grade 3 hand-foot syndrome were higher with XELOX. Treatment-related mortality within 28 days from the last study dose was 0.6% in the XELOX group and 0.6% in the FU/LV group.ConclusionXELOX has a manageable tolerability profile in the adjuvant setting. Efficacy data will be available within the next 24 months.

BackgroundThe International Duration Evaluation of Adjuvant chemotherapy project investigated whether a shorter duration of oxaliplatin-based adjuvant chemotherapy was as effective as 6 months of identical chemotherapy for resected stage III colon cancer. As part of this project, we report safety data from the Japanese ACHIEVE study (JFMC47-1202-C3).Patients and methodsACHIEVE was an open-label, multicentre trial randomising patients with stage III colon cancer to receive 3 m or 6 m of mFOLFOX6/CAPOX after surgery. Choice of regimen was declared before randomisation by a site investigator.ResultsBetween August 2012 and June 2014, 1313 patients were enrolled and, of those, 1277 were analysed for the safety analysis, with 635 in arm 6 (mFOLFOX6, n=158; CAPOX, n=477) and 642 in arm 3 (mFOLFOX6, n=161; CAPOX, n=481). Grade 3 or worse peripheral sensory neuropathy (PSN) developed in 5%/0.6% of patients receiving mFOLFOX6 in arm 6/3 (p=0.019) and 6%/1% of those receiving CAPOX in arm 6/3 (p<0.001). Similarly, grade 2 or worse PSN developed in 36%/11% of patients receiving mFOLFOX6 in arm 6/3 (p<0.001) and 37%/14% of those receiving CAPOX in arm 6/3 (p<0.001). An association between baseline creatinine clearance (CCr) and adverse events (AEs) was found that patients with CAPOX were significantly more likely to develop AEs ≥grade 3 when they had a CCr ≤50 (OR 1.67; p=0.048).ConclusionsWe confirmed in the Japanese population that the shorter duration of adjuvant chemotherapy resulted in a significant reduction of PSN. In patients with CAPOX, renal function was significantly related to severe AEs.Trial registration numberUMIN000008543, Results.

667 Background: The phase III ACHIEVE trial (JFMC47), a project of the International Duration Evaluation of Adjuvant Chemotherapy (IDEA), was established to prospectively analyze data from several randomized trials to test whether 3-month (arm 3) oxaliplatin-based adjuvant (FOLFOX4, mFOLFOX6, or XELOX) treatment is non-inferior to 6-month (arm 6) treatment in terms of disease-free survival in patients (pts) with stage III colon cancer. It aims to reveal the association between baseline characteristics and ≥ grade 3 adverse events (AEs) related to XELOX and mFOLFOX6, particularly focusing on the role of baseline creatinine clearance (CCr) on ≥ grade 3 AEs. Methods: This association was assessed using the Cox proportional hazards model. Results: During 2012–2014, 1,313 pts were randomized from 244 centers; 1,301 were included in the intention-to-treat population. Among the safety population (N = 1,277; 642, arm 3; 635, arm 6), the overall incidence of ≥ grade 3 AEs was 29% in arm 3 and 43% in arm 6 (p < 0.0001). Neuropathy of ≥ grade 2 was more frequent in arm 6 than in arm 3 (37% vs. 14%; p < 0.0001). Regarding the fluoropyrimidine backbone, grade 3–4 neutropenia was more with mFOLFOX6 than XELOX (30% vs. 12%), whereas grade 3–4 anorexia (2% vs. 5%) and grade 3–4 diarrhea (1% vs. 6%) were more with XELOX. Multivariate analysis, including treatment duration, regimen, CCr ( < 50 vs. > 50 mL/min), age, and sex, showed that CCr had a statistically significant impact on the occurrence of ≥ grade 3 AEs (hazard ratio = 0.44, p < 0.0001). Pts with CCr < 50 may have had more frequent ≥ grade 3 AEs independent of other factors, such as age. Conclusions: Grade 3 or higher AEs related to XELOX or mFOLFOX6 may be associated with the degree of CCr. Clinical trial information: UMIN 000008543.

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared with 3 months, especially in the T4 and/or N2 subgroups. These results should be considered alongside the international IDEA collaboration data.

363 Background: Irinotecan (CPT-11) has demonstrated antitumor activity against metastatic colorectal cancer used alone or with 5-fluorouracil (5FU)/leucovorin (LV). Two arms with CPT-11, 5FU, and LV (FOLFIRI) +/- cetuximab (Cmab) were originally included in N0147. However, after CALGB 89803 (J Clin Oncol. 25:3456, 2007), PETACC-3 (J Clin Oncol. 27:3117, 2009), and Accord02 (Ann Oncol. 20:674, 2009) showed no benefit to the three-drug combination in adjuvant therapy, the CPT-11 arms of N0147 were discontinued. We report the outcomes for patients given FOLFIRI +/- Cmab. Methods: Following a signed informed consent patients with resected stage III colon cancer were randomized to one of 6 arms including 12 biweekly cycles of CPT-11 180 mg/m2 d1 with LV 400 mg/m2, 5FU 400 mg/m2 bolus IV, then 46-hr IV 5FU 2,400 mg/m2 on d1-2 without (Arm B, FOLFIRI) or with Cmab (Arm E) 400 mg/m2 d1 cycle 1 then Cmab at 250 mg/m2 d1 and 8. Primary endpoint was 3-year disease-free survival (DFS). Secondary endpoints included overall survival (OS) and toxicity. Results: 156 patients (Arm B-111, Arm E-45) were enrolled; median follow-up on 81 patients in Arm B was 60.3 months and 58.2 months in Arm E for 41 patients. wtKRAS (vs mt) status was associated with improved DFS (HR=0.6 [95% CI 0.4-1.1], p = 0.09) and OS (HR 0.7 [95% CI 0.4-1.5], p = 0.38). The addition of Cmab improved DFS and OS in the overall group and within wtKRAS pts. Grade greater than III non-hematologic adverse effects were significantly increased in the Cmab arm (46% vs. 64%, p = 0.05). Conclusions: In this randomized phase III trial adjuvant FOLFIRI resulted in a 3-year DFS lower than that expected for FOLFOX. Trends for improved DFS and OS with the addition of Cmab were observed in patients with resected stage III colon cancer patients, regardless of KRAS status.

3607 Background: The standard treatment duration of adjuvant chemotherapy (CT) in patients (pts) with stage III colon cancer is 6 months. On the other hand, no clinical trial showed the optimal treatment duration of oral chemotherapeutic agents in adjuvant setting for colon cancer. Sargent et al have reported that 83% of recurrences in stage II and III pts have occurred within the first 3 years after surgery and peak was observed around one year after surgery. Therefore, to clarify the benefit of 12 months administration of Capecitabine, we designed randomized phase III trial for a comparison of 6 months treatment and 12 months treatment of capecitabine as adjuvant CT for stage III colon cancer. Methods: JFMC37 is a multicenter, randomized Phase III trial. Patients with fully resected Stage III colon or recto sigmoid cancer were eligible. Capecitabine was administered orally as tablets, 2,500 mg/m²/day for 14 days followed by a 7-days rest. Treatment is continued to 8 cycles (6 months) in arm A (A) or 16 cycles (12 months) in arm B (B). Patients were randomized 1:1 to A or B. Data size was estimated by disease free survival as primary endpoint. The statistical design is based on superiority hypothesis; 5-yrs DFS is 60% in arm A, 67% in arm B ;unilateral α=0.05, 1-β=0.8;and planed accrual is 1200 pts. Results: Between September 2008 to December 2009, 1304 patients were enrolled and then randomized. Both arms were well balanced for mean age: (A) 64.1, (B) 63.8; ECOG PS (%0/1): (A) 95.0/5.0, (B) 97.1/2.9; involvement of lymph nodes (%N0/N1/N2): (A) 77.1/19.9/3.1, (B) 76.6/19.7/3.7. Treatment completion rate for A and B were 68.2% and 43.4%. Incidences of serious adverse events (SAEs) over 1% were neutropenia: (A) 2.6%, (B) 3.8%, diarrhea: (A) 2.9%, (B) 2.1%, loss of appetite: (A) 1.3%, (B) 1.0%, fatigue: (A) 1.8%, (B) 1.2%, hand-hoot syndrome: (A) 16.4%, (B) 22.1%. Conclusions: There were no obvious differences in SAEs between arm A and arm B. Although twelve months of capecitabine showed a tendency to increase G3/4 hand-foot syndrome, we concluded that incidence of SAEs were acceptable and comparable to previously report.

484 Background: The ACTS-CC 02 trial was designed to verify the superiority of postoperative adjuvant chemotherapy with S-1/oxaliplatin (SOX) over UFT/leucovorin (LV), one of the standard oral fluoropyrimidine regimens in Japan, in terms of disease-free survival (DFS) in patients (pts) with high-risk stage III colon cancer (any T, N2, or positive nodes around the origin of the feeding arteries). The results of the safety analysis have been reported previously (Clin Colorectal Cancer, 2018). We now present the 3-year DFS results as the primary endpoint. Methods: Pts who underwent curative resection for pathologically confirmed high-risk stage III colon cancer were randomly assigned to receive either UFT/LV (300–600 mg/day of UFT according to body surface area [BSA] and 75 mg/day of LV on days 1-28, every 35 days, 5 courses) or SOX (100 mg/m2 of oxaliplatin on day 1 and 80–120 mg/day of S-1 according to BSA on days 1-14, every 21 days, 8 courses). The primary endpoint was DFS. Results: From April 2010 through October 2014, a total of 966 pts were enrolled at 260 institutions. The full analysis set, excluding pts who withdrew informed consent before protocol treatment, comprised 478 and 477 pts in the UFT/LV group and SOX group, respectively. The median age was 65.0 years. The ECOG PS was 0 in 94.0%, and the disease stage was IIIA/IIIB/IIIC in 1.3%/50.2%/48.6%. The 3-year DFS rate was 60.6% in the UFT/LV group and 62.7% in the SOX group (HR: 0.90; 95% CI: 0.74-1.09; p = 0.28); the superiority of SOX was not demonstrated. In stage IIIB, the 3-year DFS rate was 69.3% and 68.5% in the UFT/LV group and SOX group, respectively (HR: 1.01; 95% CI: 0.74-1.37; p = 0.95). In Stage IIIC, the 3-year DFS rate was 50.6% and 55.8% in the UFT/LV group and SOX group, respectively (HR: 0.82, 95% CI: 0.63-1.06; p = 0.12). Notably, in the N2b subgroup, the 3-year DFS rate was 46.0% and 54.7% in the UFT/LV group and SOX group, respectively (HR: 0.76, 95% CI: 0.55-1.05; p = 0.10). Conclusions: SOX was not shown to be superior to UFT/LV in pts with high-risk stage III colon cancer. However, the oxaliplatin-based regimen was suggested to be more effective in advanced disease, such as stage IIIC and N2b. Clinical trial information: JapicCTI-101073.

PurposeThis multicenter, randomized trial compared capecitabine plus oxaliplatin (XELOX) with bolus fluorouracil (FU) and folinic acid (FA) as adjuvant therapy for patients with stage III colon cancer.Patients and MethodsPatients who had undergone curative resection were randomly assigned to XELOX (oxaliplatin 130 mg/m2on day 1 plus capecitabine 1,000 mg/m2twice daily on days 1 to 14 every 3 weeks for 24 weeks) or a standard bolus FU/FA adjuvant regimen (Mayo Clinic for 24 weeks or Roswell Park for 32 weeks). The primary study end point was disease-free survival (DFS).ResultsThe intention-to-treat population comprised 1,886 patients; 944 patients were randomly assigned to XELOX and 942 to FU/FA (Mayo Clinic, n = 664; Roswell Park, n = 278). After 57 months of follow-up for the primary analysis, 295 patients (31.3%) in the XELOX group had relapsed, developed a new primary colon cancer, or died compared with 353 patients (37.5%) in the FU/FA group (hazard ratio [HR] for DFS, 0.80; 95% CI, 0.69 to 0.93; P = .0045). The 3-year DFS rate was 70.9% with XELOX and 66.5% with FU/FA. The HR for overall survival (OS) for XELOX compared to FU/FA was 0.87 (95% CI, 0.72 to 1.05; P = .1486). The 5-year OS for XELOX and FU/FA were 77.6% and 74.2%, respectively. Follow-up is ongoing. Preplanned multivariate and subgroup analyses supported the robustness of these findings.ConclusionThe addition of oxaliplatin to capecitabine improves DFS in patients with stage III colon cancer. XELOX is an additional adjuvant treatment option for these patients.
