2021
OBJECTIVE To evaluate the efficacy and safety of CHOP regimen based on doxorubicin hydrochloride liposome in the initial treatment of elderly patients with diffuse large B-cell lymphoma (DLBCL). METHODS Thirty-one patients with DLBCL treated from January 1, 2012 to December 31, 2019 were analyzed retrospectively, their median age was 83 (71-95) years old, and all of them were in Ⅲ-Ⅳ stage, including 17 cases who had international prognostic index (IPI) ≥ 3. The patients were treated with R-CHOP and CHOP regimens based on doxorubicin hydrochloride liposome. The efficacy and safety were evaluated during and after treatment. RESULTS A total of 219 chemotherapy cycles and 7 median cycles were performed in 31 patients. The overall response (OR) rate and complete remission (CR) rate was 80.7% (25/31) and 61.3% (19/31), respectively, as well as 2 cases (6.5%) stable, 4 cases (12.9%) progressive. The main toxicities were as follows: the incidence of grade Ⅲ -Ⅳ neutropenia was 29% (9/31); two patients (6.5%) developed degree Ⅰ-Ⅱ cardiac events, which were characterized by new degree Ⅰ atrioventricular block; there were no cardiac events requiring emergency treatment and discontinuation of chemotherapy. The 1-year, 2-year and 3-year overall survival rate was 83.9%, 77.4% and 61.3%, respectively. The 1-year, 2-year and 3-year progression-free survival rate was 77.4%, 64.5% and 61.3%, respectively. CONCLUSION The chemotherapy regimen based on doxorubicin hydrochloride liposome has better efficacy and higher cardiac safety for elderly patients with DLBCL.
