Notas

Mandatory pre-treatment screening for any regimen containing rituximab, obinutuzumab, daratumumab, isatuximab, blinatumomab, or other B-cell-depleting / plasma-cell-depleting agents (HBV reactivation risk well-documented; ASH/ASCO/AASLD all align). Rules engine consumes as boolean flag: HBsAg+ OR anti-HBc+ → RF-HBV-COINFECTION fires → forces entecavir prophylaxis (or tenofovir if entecavir resistance) before any cycle of CD20/CD38-targeted therapy. Wired into CHL, DLBCL, MM, SMZL, Burkitt 1L algorithms. Subtypes informally: - HBsAg+ (active or chronic): prophylaxis mandatory; consult hepatology - HBsAg- / anti-HBc+ (resolved or occult): prophylaxis still recommended for high-risk regimens (rituximab-containing); HBV-DNA monitoring acceptable for low-risk regimens - HBsAg- / anti-HBc- / anti-HBs+ (vaccinated): no prophylaxis - All-negative (naive): no prophylaxis; consider vaccination if multi-line therapy anticipated reviewer_signoffs: 0 # STUB — pending two Clinical Co-Lead approvals
