Thyroid Lymphoma Medication

Medication Summary
Managing large-cell lymphoma involves selecting treatment on the basis of prognostic factors. Most investigators treat patients whose IPI result is favorable by using the standard CHOP regimen, followed by irradiation consolidation in patients with Ann Arbor stages I-II. Three to 6 courses of chemotherapy are administered.[14]
Rituximab, a monoclonal antibody directed against CD20 antigen present in B-cell lymphomas, was recently combined with CHOP and compared with CHOP alone in a randomized study of patients aged >60 years with diffuse large-cell lymphoma. The combination of rituximab and CHOP improved rates of complete response, failure-free survival, and survival. The results can be applied to primary thyroid lymphoma. Although the study did not include patients younger than 60 years, younger patients have received rituximab.
Patients who present with Ann Arbor stage I and an IPI of 0 with tumor diameters smaller than 5 cm could be treated with 3 courses of CHOP followed by local irradiation. The role of rituximab in patients with these favorable presentations has not been explored, but most clinicians include it in the treatment regimen. All other patients receive 6 courses of CHOP and radiotherapy. Consider investigational regimens in patients with IPI scores greater than 0. In general, the addition of rituximab provides benefit in survival and disease-free survival rates, and the results are also assumed to apply to primary thyroid large-cell lymphomas.
Antineoplastic regimens
Class Summary
These agents inhibit cell growth and proliferation.
Cyclophosphamide (Cytoxan, Neosar)
Chemically related to nitrogen mustards. Alkylating agent; mechanism of action of active metabolites may involve cross-linking of DNA, which may interfere with growth of normal and neoplastic cells.
Doxorubicin (Adriamycin, Rubex)
Intercalates DNA and inhibits topoisomerase II; produces free radicals that may cause destruction of DNA and inhibit growth of neoplastic cells.
Vincristine (Oncovin, Vincasar VFS)
Mechanism of action is uncertain. May involve decrease in reticuloendothelial cell function or increase in platelet production.
Prednisone (Deltasone, Meticorten, Orasone, Sterapred)
Immunosuppressant for treatment of autoimmune disorders. May decrease inflammation by reversing increased capillary permeability and suppressing PMN activity.
Rituximab (Rituxan)
Genetically engineered chimeric murine/human monoclonal antibody against CD20 antigen on surface of normal and malignant B-lymphocytes. Antibody is IgG1 kappa immunoglobulin.
Not to be administered as IV bolus.
