The Southwest <strong>Oncology</strong> Group (SWOG) is in the process<br />

<strong>of</strong> designing a randomized trial that compares FOLFIRI-<br />

NOX with FOLFOX, to determine whether irinotecan is an<br />

essential component <strong>of</strong> the regimen. Another approach is to<br />

ascertain which patients would be most likely to develop<br />

toxicity from irinotecan and adjust doses accordingly.<br />

UGT1A1 is the enzyme responsible for clearing SN-38, the<br />

active metabolite <strong>of</strong> irinotecan; germline polymorphisms in<br />

the UGT1A1 gene are known to reduce enzymatic activity. 32<br />

Thus, patients treated with FOLFIRINOX who have different<br />

UGT1A1 genotypes may tolerate different doses <strong>of</strong><br />

irinotecan. Using genotype-guided dosing, investigators at<br />

the University <strong>of</strong> Chicago will soon open a phase I study to<br />

establish the optimal safe doses <strong>of</strong> irinotecan in the mFOL-<br />

FIRINOX regimen for each <strong>of</strong> three UGT1A1 genotype<br />

groups (*1*1, *1*28, and *28*28).<br />

Conclusion<br />

After so many negative randomized trials <strong>of</strong> gemcitabine<br />

doublets, the unprecedented outcomes achieved with the<br />

FOLFIRINOX regimen clearly represent a major treatment<br />

advance for those patients with pancreatic cancer who have<br />

a good performance status. No other randomized study has<br />

ever achieved a median survival <strong>of</strong> nearly a year. In no other<br />

trial have we even whispered about an 18-month survival in<br />

a proportion <strong>of</strong> patients with metastatic disease. No other<br />

phase III study has achieved such a high objective response<br />

rate. And despite substantial, though manageable toxicities,<br />

FOLFIRINOX also helps patients feel better for longer than<br />

if they received gemcitabine, a drug used principally for its<br />

effect on symptoms. Remarkably, this new drug combination<br />

is even cost-effective.<br />

The investigators in this study are to be commended not<br />

only for the decade they spent in developing the highly<br />

active FOLFIRINOX regimen. They are also to be applauded<br />

for a very well-designed pivotal study, which tested this<br />

therapy in a uniform population <strong>of</strong> patients (all metastatic),<br />

who, with their good performance status, were most likely to<br />

tolerate the rigors <strong>of</strong> the multidrug combination and were<br />

thus most able to benefit from it.<br />

Unanswered questions remain about the optimal way to<br />

dose the component drugs to minimize toxicity while preserving<br />

activity. Upcoming studies will address the potential<br />

role <strong>of</strong> this regimen in other disease settings and will use<br />

FOLFIRINOX as a platform on which to add new agents.<br />

It has been a long journey, but with the advent <strong>of</strong> FOL-<br />

FIRINOX, we are finally beginning to make progress against<br />

this dismal disease.<br />
