Systemic capillary leak syndrome in a patient receiving adjuvant oxaliplatin for locally advanced colon cancer

Abstract

Colorectal cancer is the third most common cancer diagnosed in the USA each year. Oxaliplatin, a platinum-based chemotherapy agent, is part of the standard adjuvant chemotherapy regimen FOLFOX (oxaliplatin with 5-fluorouracil [5-FU] and leucovorin [LV]) for the treatment of stage III and some high-risk stage II colorectal cancers. Although oxaliplatin is generally well tolerated, certain side effects such as nausea, vomiting, and peripheral neuropathy are common. We report a case of oxaliplatin-induced capillary-leak syndrome in a 63-year-old man undergoing his 12th and final cycle of FOLFOX for stage III colorectal cancer. To our knowledge, this is the first case of systemic capillary leak syndrome (SCLS) reported in association with oxaliplatin. Currently, there is no prevention for SCLS. Documenting future cases of SCLS attributed to oxaliplatin is vital, as SCLS is associated with significant morbidity and mortality and no standard treatments beyond supportive care measures exist. Early recognition and diagnosis are therefore essential to improving patient outcomes.
