Treatment of High-Grade Non-Hodgkin Lymphoma

Primary Treatment Recommendation

The standard treatment of choice for CD20-positive high-grade Non-Hodgkin Lymphoma is R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) administered for 6-8 cycles every 21 days, as recommended by the American College of Physicians 1

For CD20-positive Diffuse Large B-Cell Lymphoma, six to eight cycles of R-CHOP given every 21 or 14 days is the established standard treatment, according to the American Society of Clinical Oncology 1
Dose intensity should be maintained when possible, as dose reductions compromise efficacy, as stated by the American College of Physicians 2

Herpes zoster prophylaxis should be considered for proteasome inhibitor-based regimens, as recommended by the National Comprehensive Cancer Network 3
PJP prophylaxis should be considered for bendamustine/rituximab combinations, according to the National Comprehensive Cancer Network 3
Hepatitis B screening (HBsAg and anti-HBc) is mandatory before starting rituximab, with prophylactic entecavir for HBsAg-positive patients, as recommended by the National Comprehensive Cancer Network 3

Response evaluation should be performed after 2-4 cycles to exclude disease progression, as stated by the American College of Physicians 2
PET-CT is preferred for response assessment in FDG-avid lymphomas, according to the American College of Physicians 1

Consolidative radiotherapy may be considered for sites of initial bulky disease (>2.5 cm residual after chemotherapy), as recommended by the European Society for Medical Oncology 4
Consolidative radiotherapy may be considered for PET-positive residual disease after induction chemotherapy, according to the European Society for Medical Oncology 4

High-dose chemotherapy followed by autologous stem cell transplantation is the treatment of choice for patients with relapsed or refractory high-grade NHL, as recommended by the American Society of Clinical Oncology 1
Achieving negative PET should be the goal of salvage therapy, according to the European Society for Medical Oncology 4

History, physical examination, and laboratory analysis should be performed every 3 months for the first 6 months, as recommended by the American College of Physicians 1
Thyroid function monitoring is recommended if the neck was irradiated, according to the American College of Physicians 1, 2
