Patients who relapse within a year now go to CAR-T rather than more chemotherapy.","summary":"CHOP dates from the 1970s; adding rituximab (2002) raised cure rates by about 15 percentage points. Pola-R-CHP swaps vincristine for polatuzumab vedotin and improved progression-free survival (POLARIX); PET-guided shortening to four cycles suffices for low-risk early-stage disease (FLYER). Patients who relapse within a year now go to CAR-T rather than salvage chemotherapy and autologous transplant; bispecific antibodies (glofitamab, epcoritamab) are moving into first line combinations. BR (bendamustine-rituximab) and R-CVP are gentler regimens for indolent lymphomas. 'Chemoimmunotherapy' in lymphoma means antibody plus chemotherapy, not checkpoint inhibitors.","asOf":"2026-09-09","wikipedia":"https://en.wikipedia.org/wiki/R-CHOP","links":[{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/R-CHOP"}],"tags":[],"related":["anthracycline","deauville","salvage-therapy","chemotherapy-regimen"],"cancers":["dlbcl","cll"],"sections":["chemotherapy","immunotherapy"],"technologies":[],"targets":[],"drugs":["rituximab","cyclophosphamide","doxorubicin","vincristine","bendamustine"],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Treatment
