A case of delayed oxaliplatin-induced pseudo-obstruction: an atypical presentation of oxaliplatin neurotoxicity.

Chemotherapy-induced neurotoxicity is a serious complication of cancer treatment. Oxaliplatin, a third-generation platinum drug, has become one of the first-line therapies used in the treatment of metastatic colorectal cancer. Peripheral neuropathy is a common complication of platinum-based chemotherapy. Most commonly a sensory neuropathy occurs with cold-triggered symptoms in the acute phase and numbness and painful paresthesias as a late presentation. Autonomic neurotoxicity and late presentation, months after cessation of the therapy, has rarely been described. We report a patient who clinically presented with a pseudo-obstruction months after treatment with oxaliplatin for metastatic colorectal cancer. Intestinal adhesions and relapsing malignancy were carefully excluded. By exclusion the pseudo-obstruction was attributed to a toxic oxaliplatin-induced autonomic neuropathy which slowly improved during months of follow-up.
