⚠ BSA caps are institutional/protocol-specific — not a global standard. "No cap" is correct for most regimens unless your protocol or PI explicitly mandates one. Verify before applying.

Regimen Selection
Search by drug, regimen, or condition only — do not type patient names, MRNs, or dates of birth. This text is sent to a third-party AI service.
Dose Reduction (MD-Ordered)
% 0 = full dose
e.g. 20 = 20% dose reduction
Carboplatin AUC Override
Blank = use the regimen's protocol AUC.
Only affects Calvert-dosed (carboplatin) agents.
⚠ Cumulative Dose History
Anthracycline lifetime limit: 450–550 mg/m² (doxorubicin) · Bleomycin: ~400 units · Oxaliplatin neuropathy risk: >500 mg/m²
