Objective: To assess the immunosuppressive effect of R-CHOP in patients with B-cell lymphoma at 2 years. Methods: Parameters of humoral and cell-mediated immunity were assessed in 89 patients with diffuse large B-cell lymphoma or follicular lymphoma before and after 6-8 cycles of R-CHOP-14 or R-CHOP-21 regimen. Results: Data on pre- and posttreatment serum IgG (sIgG) levels were available for all 89 patients, while the corresponding data on serum CD20+, CD3+, CD4+, and CD8+ lymphocyte counts were available in only 43. Median sIgG levels significantly decreased from 1,221 mg/dl (baseline) to 733 mg/dl (after chemotherapy) (p < 0.001). Although CD20+ and CD4+ cell counts decreased (p < 0.001), no significant effect of chemotherapy on CD3+ and CD8+ cell counts was observed. CD20+ cell counts were restored to baseline levels at the 12-month follow-up. sIgG levels and CD4+ cell counts were not completely restored at 24 months, indicating a sustained immunosuppressive effect of R-CHOP in these patients. The incidence of infections over the 2-year period was 16.3-23.6%. Conclusion: The immunosuppressive effect of R-CHOP in newly diagnosed cases of B-cell lymphoma tends to persist for >2 years, although sIgG levels were restored more quickly than CD4+ cell counts.
