  "abstract": "Rationale\n\nOxaliplatin, a platinum-based chemotherapeutic widely used in colorectal, hepatobiliary, and pancreatic malignancies, commonly causes a symmetric, cold-induced sensory neuropathy. Rarely, it has been linked to immune-mediated Guillain-Barré Syndrome (GBS), which can be misattributed to drug-induced sensory neuropathy and delay diagnosis. Distinguishing the two is critical because GBS can progress to respiratory failure and death.Patient concerns\n\nA 77-year-old woman with concurrent metastatic cholangiocarcinoma and colorectal carcinoma developed acute, symmetric, ascending motor weakness with clinically preserved sensation approximately 2 weeks after her last cycle of gemcitabine, oxaliplatin, leucovorin, and 5-fluorouracil (GOLF), rapidly progressing to an inability to ambulate.Diagnosis\n\nNeurological examination and cerebrospinal fluid analysis (albuminocytologic dissociation) were consistent with GBS, and nerve conduction studies demonstrated absent motor and sensory responses, indicating a severe axonal variant (AMSAN); sensory involvement was electrodiagnostic rather than clinical. An extensive infectious, autoimmune, and paraneoplastic workup was negative, supporting a diagnosis of presumed oxaliplatin-related GBS; a Naranjo score of 4 indicated a \"possible\" drug association.Interventions\n\nShe received 5 sessions of therapeutic plasma exchange followed by 4 sessions of intravenous immunoglobulin.Outcomes\n\nNo meaningful neurological recovery occurred; she developed progressive respiratory failure requiring mechanical ventilation and died.Lessons\n\nClinicians should maintain a high index of suspicion for GBS in patients on platinum-based chemotherapy who develop abrupt, symmetric motor weakness after common causes have been ruled out. Because causality is difficult to establish, the association remains presumed; early recognition, prompt immunotherapy, and pharmacovigilance are essential to reduce mortality.",
