摘要: Lymphoplasmacytic lymphoma (LPL) is an indolent with moderate sensitivity to conventional chemotherapy. This study investigated whether the addition of rituximab standard chemotherapy improves treatment outcome in LPL and subgroup patients fulfilling criteria Waldenstroem's macroglobulinemia (WM). A total 69 previously untreated were enrolled into trial; 64 evaluable for outcome. In all, 48 fulfilled WM. Patients randomly assigned R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine prednisone, n=34) or CHOP (n=30). resulted significantly higher overall response (OR) rate (94 vs 67%, P=0.0085) WM (91 60%, P=0.0188). With a median observation time 42 months, induced longer failure (TTF) 63 months 22 arm (P=0.0033) (P=0.0241). There was no major difference treatment-associated toxicity between both groups. These data indicate that front-line
