What does the R-CHOP chemoimmunotherapy procedure involve?

R-CHOP is a standard treatment for diffuse large B-cell lymphoma, combining rituximab (a monoclonal antibody) with four chemotherapy drugs: cyclophosphamide, doxorubicin, vincristine, and prednisone. The regimen is administered intravenously over several hours in an outpatient setting, repeated every 21 days for a total of 6 cycles. This approach targets both the lymphoma cells and the immune system to enhance treatment efficacy.
