Metastatic pancreatic cancer remains resistant to conventional systemic treatments, with median overall survival (OS) being less than 1 year. Due to toxic effects of combination cytotoxic therapies, rational approaches with targeted therapies have been attempted in hope of minimizing toxic effects. Erlotinib hydrochloride is the only US Food and Drug Administration–approved molecularly targeted treatment for pancreatic cancer; however, the combination with gemcitabine hydrochloride improved median OS by only 2 weeks compared with gemcitabine alone.
1 Therefore, traditional cytotoxics have been the mainstay of treatment. FOLFIRINOX (oxaliplatin, irinotecan hydrochloride, leucovorin calcium, and fluorouracil) has the highest reported objective response rate, with a median OS just under 1 year, but at the cost of increased toxic effects.
2 The applicability of FOLFIRINOX is therefore limited to younger patients with a good performance status, near-normal liver function, and a willingness to undergo aggressive therapy for metastatic disease. Gemcitabine and nab-paclitaxel provides another treatment option, albeit with a shorter median OS.
