The World Journal of Emergency Surgery recommends piperacillin/tazobactam as the first-line therapy for critically ill or immunocompromised patients, including cancer patients, at a dose of 6g/0.75g loading dose followed by 4g/0.5g every 6 hours or 16g/2g by continuous infusion 1, 2
For patients with documented beta-lactam allergy, eravacycline 1 mg/kg every 12 hours is the preferred alternative 1, 2
Ertapenem 1g every 24 hours is an alternative regimen for patients with inadequate source control or at high risk of infection with ESBL-producing organisms 1, 2
Eravacycline 1 mg/kg every 12 hours is also an alternative regimen for patients with inadequate source control or at high risk of infection with ESBL-producing organisms 1, 2

Endoscopic biliary stenting is preferred over surgical bypass for palliation of jaundice in unresectable disease, as recommended by Gut and Annals of Oncology 3, 5
Urgent biliary drainage with broad-spectrum antibiotics is essential in patients with cholangitis due to obstructive jaundice, according to Annals of Oncology 5

Cancer patients are at increased risk for severe bacterial infections due to immunocompromise from both the malignancy and cancer treatments, as stated by the Journal of the National Comprehensive Cancer Network 7

Inadequate biliary drainage may increase the risk of sepsis and treatment failure, according to Gut 3, 4
Delaying appropriate antimicrobial therapy in immunocompromised patients can lead to rapid clinical deterioration, as warned by the Journal of the National Comprehensive Cancer Network 7
