Purpose: Although FOLFIRINOX has become one of <strong>the</strong> standard option for <strong>the</strong><br />

treatment of aPDAC, tolerability and safety issues, with particular regard to<br />

hematologic toxicity and increased risk of AE in pts carrying biliary stents, may<br />

represent a barrier for <strong>the</strong> routinely adoption in clinical practice.<br />

Methods: The clinical reports of 36 aPDAC pts undergone 1st-line FOLFIRINOX in<br />

2 different institutions were reviewed. Toxicities, activity and efficacy were<br />

determined according to 1) primary G-CSF prophylaxis (dd 7-9-11; yes/no 21/15<br />

pts), and 2) presence/absence biliary stent.<br />

Results: Pts characteristics: N°: 36; cycles: 241, M/F: 22/14; median age: 57 yrs [range<br />

37-70]; ECOG PS 0/1: 33/3; stage III/IV: 10/26. G3/4 toxicity occurred in 50% reduction in CA19.9.<br />

Conclusions: These data indicate that FOLFIRINOX seems to be well tolerated and<br />

easily manageable in young (50%, no PD after 6 months of CT were randomized to O (arm A) or MS at 37.5 mg<br />

daily until PD or a maximum of 6 months (arm B). Functional polymorphisms of 6<br />

genes involved in sunitinib activity, metabolism and transport (VEGFA, VEGFR-2,<br />

CYP3A5, CYP1A1, ABCB1, ABCG2) were studied in genomic DNA from baseline<br />

blood samples, using PCR Taqman®-probes-based assays. Associations of genotypes<br />

with overall survival (OS) and progression-free survival (PFS) were evaluated by<br />

Log-rank test. Genotyping was successfully performed in all <strong>the</strong> DNA samples of 43<br />

consenting pts of 55 enrolled in <strong>the</strong> trial (78%; arm A/B: 83%/73%; p = 0.39).<br />

Significantly longer OS was observed in 7 pts harbouring <strong>the</strong> ABCB1 3435TT<br />

genotype (group-1; median OS 20 months) as compared to 36 pts with 3435CC/CT<br />

genotype (group-2; median OS 7 months; p = 0.027). Median OS was 26 months in 4<br />

group-1 arm B pts, 7 months in 15 group-2 arm B pts (p = 0.12); 16 months in 3<br />

group-1 arm A pts and 9 months in 21 group-2 arm A pts (p = 0.67). No OS<br />

difference was observed in 28 pts harbouring <strong>the</strong> VEGFA -634GC-CC genotype<br />
