Frassinetti, F.Di Costanzo, AM.Bochicchio on behalf of ITACA-S group PRESENTED BY MARIA DI BARTOLOMEO • The standard recommendation for resectable gastric cancer was surgery (D1 dissection) • Meta-analysis of literature data showed a small but significant benefit with chemotherapy1 • Large, patient-level meta-analysis2 confirmed that 5-FUbased chemotherapy is associated with a statistically significant benefit: • OS HR 0.82 (95% CI 0.76-0.90; P< .001) DFS HR 0.82 (95% CI 0.75-0.90; P< .001) Our choice of 5-FU/LV regimen as control arm was based on the results of meta-analysis of randomized clinical trials (1 Mari, Ann Oncol,2000; 2GASTRIC, JAMA 2010) ITACA-S Bajetta, Cascinu, Di Costanzo, De Vita, Ann Oncol, 2002 JNCI, 2007 JNCI, 2008 Ann Oncol, 2007 Stage T3-4/N+ T3-4/N+ T3-4/N+ I-IIIB Pts 137/137 196/201 128/130 112/113 EAPFU/LV PELFwk PELF ELFE Follow-up FU/LV Follow-up Follow-up HR 0.93 0.95 0.90 0.91 5-y OS control arm 49% 50% 48.7% 43.5% Experimental Arm Control arm ITACA-S • • • FOLFIRI -> less hematological, renal and neurological toxicity and less stomatitis than cisplatin combinations Docetaxel (TXT), CDDP and 5-FU regimen is active in terms of objective response and OS, but several grade 3-4 AEs Treatment sequence FOLFIRI TXT/CDDP • Minimize AEs by considering each drug toxicity profile • Feasibility of the sequence was documented in the ITMO trial2 • Could more active drugs improve the benefit of FU/LV chemotherapy in patients radically resected with extended lymph nodes dissection?

However it is: - not more effective than FU/LV - more toxic than FU/LV • According to these results there is no indication to use polychemotherapy regimen in adjuvant setting for any stage of gastric cancer ITACA-S Sponsor Steering committee • Istituto Farmacologico Mario Negri Milano • E.Bajetta (PI), B.Daniele, D.Nitti, R.
