PURPOSE In a randomized clinical trial (European Organization for the Research and Treatment of Cancer [EORTC] no. 40813) on adjuvant chemotherapy in gastric cancer, results obtained after administration of the FAM2 regimen (fluorouracil [5-FU], doxorubicin, and mitomycin) were compared with results obtained after surgery alone to assess the effect of this regimen on overall survival, time to progression, and disease-free interval. PATIENTS AND METHODS Three hundred fourteen patients who had undergone curative resection for stage II or stage III (International Union Against Cancer [UICC] 1978) gastric adenocarcinoma were randomized to receive chemotherapy (treatment arm) or no further treatment (control arm). The chemotherapy schedule was repeated every 43 days for seven cycles. The log-rank test and the Cox model were used for statistical analysis. RESULTS Of 314 patients, 159 comprised the control group and 155 the FAM2 group. Nineteen FAM2 patients never received chemotherapy. The median number of cycles was five. Of the patients started on adjuvant treatment, severe hematologic and nonhematologic toxicity (grades 3 or 4, World Health Organization [WHO] scale) occurred, respectively, in 6% to 9% and in 1% to 29% of cases. The overall 5-year survival rate was 70% for stage II and 32% for stage III patients. No statistically significant difference was found between overall survival of the two treatment arms (P = .295). However, time to progression was significantly delayed in the FAM2 arm (P = .020) and disease-free survival showed borderline significance (P = .068). CONCLUSION FAM2, in view of its high toxicity, cannot be advocated as standard adjuvant treatment for gastric cancer. Large-scale clinical trials using more active, less toxic regimens are required to demonstrate whether adjuvant chemotherapy provides any real benefit.

PURPOSE: The efficacy of adjuvant chemotherapy in gastric cancer is controversial. We conducted a phase III, randomized, multicentric clinical trial with the goal of assessing the efficacy of the combination of mitomycin plus tegafur in prolonging the disease-free survival and overall survival of patients with resected stage III gastric cancer. PATIENTS AND METHODS: Patients with resected stage III gastric adenocarcinoma were randomly assigned, using sealed envelopes, to receive either chemotherapy or no further treatment. Chemotherapy was started within 28 days after surgery according to the following schedule: mitomycin 20 mg/m2 intravenously (bolus) at day 1 of chemotherapy; 30 days later, oral tegafur at 400 mg bid daily for 3 months. Disease-free survival and overall survival were estimated using the Kaplan-Meier analysis and the Cox proportional hazards model. RESULTS: Between January 1988 and September 1994, 148 patients from 10 hospitals in Catalonia, Spain, were included in the study. The median follow-up period was 37 months. The tolerability of the treatment was excellent. The overall survival and disease-free survival were higher in the group of patients treated with chemotherapy (P = .04 for survival and P = .01 for disease-free survival in the log-rank test). The overall 5-year survival rate and the 5-year disease-free survival rate were, respectively, 56% and 51% in the treatment group and 36% and 31% in the control group. CONCLUSION: Our positive results are consistent with the results of recent studies; which conclude that there is a potential benefit from adjuvant chemotherapy in resected gastric cancer.

Abstract Background Surgery is the only treatment option for operable gastric cancer. The CLASSIC and ACTS-GC studies showed that the 5-year overall survival (OS) of patients with stage III gastric cancer undergoing D2 gastrectomy is still very low. Whether adjuvant nanoparticle albumin-bound paclitaxel (nab-paclitaxel) combined chemotherapy is more effective than the XELOX standard adjuvant chemotherapy in patients with stage III gastric cancer has not been confirmed. Methods This is a multicenter, open-label, phase III clinical study. In this trial, 616 patients with locally advanced stage III gastric cancer that underwent curative D2 radical surgery and achieved R0 are planned to be included. Patients will be randomized 1:1 to nab-paclitaxel combined with S-1 (AS) vs. oxaliplatin combined with capecitabine (XELOX). XELOX group: Patients assigned to the XELOX group received eight 3-week cycles of oral capecitabine (1000 mg/m2) twice daily on days 1–14 of each cycle plus intravenous oxaliplatin 130 mg/m2 on day 1 of each cycle. AS group: AS group received eight 3-week cycles of oral S-1 (80–120 mg) (< 1.25 m2, 40 mg; 1.25 to < 1.5 m2, 50 mg; and > 1.5 m2, 60 mg) twice daily on days 1–14 plus intravenous nab-paclitaxel 120 mg/m2 on days 1 and 8 of each cycle. The primary endpoint was the 3-year disease-free survival (3-year-DFS) defined as the time from randomisation to the time of recurrence of the original gastric cancer, development of a new gastric cancer, or death from any cause. The secondary endpoints were the overall survival, (defined as the time from the date of randomisation to date of death from any cause) and safety (any adverse event). Discussion Compared with previous studies, this study includes nab-paclitaxel based on S-1 adjuvant chemotherapy, which is expected to achieve better efficacy and lower toxicity than the standard treatment. This study is the first clinical study to evaluate the safety and efficacy of nab-paclitaxel combined with S-1 in patients with stage III gastric cancer after D2 radical resection. Trial registration This clinical trial has been registered with ClinicalTrials.gov, registration number: NCT04135781, on October 20th, 2019.

Clinical Trial Information

TPS196 Background: Base on the ACTS-GC trial, adjuvant chemotherapy with S-1 at a dose of 80 mg/m2/day (4 weeks on and 2 weeks off, repeated for one year) is the standard care for stage II/III gastric cancer (GC) patients (pts) after D2 gastrectomy. As Japan has the most aged population in the world, the actual number of elderly GC pts is still increasing. While elderly pts population is heterogeneous and is conceptually composed of “fit”, “vulnerable” and “frail” pts, full-dose adjuvant chemotherapy tends to be given to fit elderly pts in clinical practice. However, it has not been determined yet whether S-1 should be administered to vulnerable pts over 80. Actually, according to the questionnaire survey conducted on 58 institutions of Stomach Cancer Study Group of Japan Clinical Oncology Group, S-1 was administered on only 15% to stage II/III pts > = 80 years old suggesting that surgery alone is generally considered as community standard for vulnerable pts. It is an urgent need to establish the standard adjuvant treatment of the vulnerable elderly GC pts. Methods: The study is designed to confirm the superiority of S-1 treatment group over surgery alone group focusing on vulnerable > = 80 years old pts in stage II / III GC after curative resection. The “vulnerable” is defined in this study based on the three factors [creatinine clearance (Ccr), weight loss, type of surgery] considered to have the most influence on compliance of S-1, that is Ccr > = 30ml/min, weight loss < 15% and total gastrectomy, or 80 > Ccr > = 30ml/min, weight loss < 15% and other than total gastrectomy. Initial dose was reduced by 1 rank from the standard dose. The primary endpoint is overall survival (OS) and the secondary endpoints are relapse free survival, time to treatment failure, treatment continuity, relative dose intensity and adverse events. We assume expected 3-year OS in surgery alone arm will be 55% and S-1 treatment will improve the survival by more than 10%. 370 pts are required to provide 75% of power and 5% one-sided alpha error, with 4 years accrual and 3 years of follow up period. The trial has started from January 2017. Clinical trial information: UMIN000025742. Clinical trial information: 000025742.

Purpose: To evaluate the survival benefit of adjuvant chemotherapy after curative resection in serosa-negative gastric cancer patients (excluding patients who were T1N0), we conducted a multicenter phase III clinical trial in which 13 cancer centers in Japan participated. Patients and Methods: From January 1993 to December 1994, 252 patients were enrolled into the study and allocated randomly to adjuvant chemotherapy or surgery alone. The chemotherapy comprised intravenous mitomycin 1.33 mg/m2, fluorouracil (FU) 166.7 mg/m2, and cytarabine 13.3 mg/m2 twice weekly for the first 3 weeks after surgery, and oral FU 134 mg/m2 daily for the next 18 months for a total dose of 67 g/m2. The primary end point was relapse-free survival. Overall survival and the site of recurrence were secondary end points. Results: Ninety-eight percent of patients underwent gastrectomy with D2 or greater lymph node dissection. There were no treatment-related deaths and few serious adverse events. There was no significant difference in relapse-free and overall survival between the arms (5-year relapse-free survival 88.8% chemotherapy v 83.7% surgery alone; P = .14 and 5-year survival 91.2% chemotherapy v 86.1% surgery alone; P = .13, respectively). Nine patients (7.1%) in the chemotherapy arm and 17 patients (13.8%) in the surgery-alone arm had cancer recurrence. Conclusion: There was no statistically significant relapse-free or overall survival benefit with this adjuvant chemotherapy for patients with macroscopically serosa-negative gastric cancer after curative resection, and there was no statistical difference between the two arms relating to the types of cancer recurrence. We do not recommend adjuvant chemotherapy with this regimen for this population in clinical practice.

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.

108 Background: An adjuvant chemotherapy with S-1 has become the standard treatment for patients (pts) with stage II/III gastric cancer (GC) who have undergone gastrectomy with D2 dissection in Japan, but it is assumed that the survival benefit for stage III pts who received S-1 is modest. S-1 plus docetaxel has shown that the response rate and median overall survival (OS) were 56% and 14.3 months in pts with advanced GC. The aims of this phase II study were to evaluate the feasibility and safety of adjuvant S-1 plus docetaxel in pts with stage III GC with D2 surgery. Methods: Pts with pathological stage III GC who underwent gastrectomy with D2 dissection received oral S-1 (80 mg/m2/day) administration for 2 consecutive weeks and intravenous docetaxel (40 mg/m2) on day 1, repeated every 3 weeks (1 cycle). The treatment was started within 45 days after surgery, and repeated for 4 cycles, followed by S-1 administration until 1 year after surgery. The primary endpoint was feasibility of the 4 cycles administration of S-1 plus docetaxel; secondary endpoints were safety, progression-free survival (PFS), OS, and feasibility of S-1 administration until 1 year after surgery. Results: We enrolled 53 pts, 42 males and 11 females with a median age of 65 years (range, 43-78), between May 2007 and August 2008. Pathological stages included IIIA in 36 pts and IIIB in 17 pts. The feasibility of planned 4 cycles of treatment was 77.4% (95% CI 63.8-87.7%, p < 0.001) with 41 pts out of 53 pts. Grade 4 neutropenia was observed in 28% of pts with grade 3 febrile neutropenia in 9%. Non-hematological toxicities of grade 3 or more involved fatigue in 6%, anorexia in 9%, and nausea in 6%. No treatment-related deaths occurred. Reasons for discontinuation were recurrent cancer in 1 pt, adverse events in 10, and miscellaneous in 1, respectively. 3 year overall survival was 78.8% (95% CI 68.4-90.7) and 3 year disease free survival was 50.3% (95% CI 34.4-73.3). Conclusions: Adjuvant S-1 plus docetaxel therapy is feasible and has only moderate toxicity in stage III gastric cancer pts. We believe that this regimen will be a candidate for future phase III trials seeking the optimal adjuvant chemotherapy for stage III gastric cancer patients.

3548 Background: Colon cancer is potentially curable by surgery in the early stages of the disease. Adjuvant chemotherapy improves disease-free and overall survival in patients with stage III disease, but the magnitude of benefit in stage II colon cancer is less clear. A previous Cochrane systematic review and meta-analysis (SR/MA) found improved disease-free, but not overall survival (Figueredo et al., 2008). An updated SR/MA was performed to determine the effects of adjuvant chemotherapy on disease-free and overall survival in patients with stage II colon cancer. Methods: Relevant databases (MEDLINE, EMBASE, and Cochrane) were independently searched by all authors, using the same search strategy employed in the original study (1/1988 to 9/2012). Randomized trials containing data on stage II colon cancer patients undergoing adjuvant 5-fluorouracil (5FU) chemotherapy versus observation were included. Pooled results were expressed as hazard ratios (HR) whenever possible, or risk ratios (RR), with 95% confidence intervals (95%CI) using a random effects model. Results: Seven studies were identified, and included in the final SR/MA. Six of the 7 studies were included in the disease-free survival analysis (n=4587). Adjuvant 5FU was associated with better disease-free survival (RR 0.84 (95%CI 0.75-0.94)). All 7 studies (n=5353) were included in the overall survival analysis showing an improvement with adjuvant 5FU (HR 0.87 (95%CI 0.78-0.97)). There was no evidence of heterogeneity across the studies (I2 = 0% for all analyses). Conclusions: In stage II colon cancer, adjuvant 5FU chemotherapy statistically improves both disease-free and overall survival. Our SR/MA demonstrates, for the first time, an overall survival advantage with adjuvant chemotherapy in stage II colon cancer.

95 Background: To evaluate the risk of recurrence in patients with pathologically staged Ib, according to the American Joint Committee on Cancer (AJCC) 2002 staging system, gastric cancer (GC) in the phase III adjuvant chemoradiotherapy in stomach tumors (ARTIST) trial. Methods: Among 458 GC patients enrolled in ARTIST, 99 had stage Ib (T2N0 or T1N1) disease. Patients were randomly assigned to receive adjuvant chemoradiotherapy with capecitabine plus cisplatin (XP, n = 50)) or chemoradiotherapy (XPRT, n = 49). Kaplan-Meier method was used to calculate disease-free survival (DFS). Cox proportional hazard models were employed to determine associations between the addition of radiotherapy to XP and DFS after adjustment for patient and disease characteristics. Additionally, analyses were performed according to the AJCC 2010 staging system. Results: With 7 years of follow-up, there were 18 recurrences. The 5-year DFS rates were 88% and 84% in XP and XPRT patients, respectively (P = 0.537). When we reviewed the pathologic stages of the patients according to the AJCC 2010 system, stage migration from Ib to II occurred in 71% of the patients: 98% of the T2N0 patients were reclassified as T3N0, and 42% of the T1N1 patients were reclassified as T1N2. The patients classified as stage Ib according to the AJCC 2002 system and reclassified as stage II exhibited worse, although statistically insignificant, prognosis than the patients who remained in stage Ib (5-year DFS 83% vs. 93%, P = 0.183, HR 1.178, 95% CI 0.420-3.311, P = 0.158). When we compared 5-year DFS in 70 stage II (AJCC 2010 system) patients, the addition of radiotherapy to XP chemotherapy resulted, although again statistically insignificant (P = 0.234), in worse outcome in XPRT arm (77%) than in XPRT arm (88%). Conclusions: This subgroup analysis confirms the clinical relevance of the AJCC 2010 staging system in GC. The role of adjuvant chemotherapy in stage II GC warrants further investigation.
