We evaluated real-world effectiveness and safety of CT-P10 (Truxima®) compared with originator rituximab in diffuse large B-cell lymphoma (DLBCL) treatment. Before and after the introduction of CT-P10 to our institute (November 2017), 221 newly-diagnosed DLBCL patients received rituximab with standard cyclophosphamide, vincristine, doxorubicin and prednisone. Patients received originator rituximab throughout (n = 95), switched from originator rituximab to CT-P10 (n = 36), or received CT-P10 throughout (n = 90). There were no significant differences between groups in overall response rate (91.6% vs 94.4% vs 96.7%, respectively; p = 0.403) or complete response rate (84.2% vs 77.8% vs 86.7%, respectively; p = 0.467). Kaplan–Meier survival curves also showed no significant differences in progression-free survival and overall survival between groups (log-rank p = 0.794 and p = 0.955, respectively). Safety profiles were comparable between treatment groups. These data support the ability of CT-P10 to successfully replace originator rituximab in DLBCL treatment and, given the lowered financial barrier, to improve the overall prognosis for DLBCL patients.

Overall, more than 50% of marginal zone lymphoma (MZL) patients experience a relapse within 10 years. This phase II trial was conductedto assess the efficacy and safety of oxaliplatin-prednisone (Ox-P) chemotherapy for patients with relapsed or refractory MZL. Patients received oxaliplatin 130 mg/m2on day 1 and prednisone 100 mg/day on days 1–5 of each cycle. A total of 38 patients were enrolled. The median age of the 34 (16 males, 18 females) evaluated patients was 53 (range = 27–74) years. There were seven complete responses (20.6%) and 15 partial responses (44.1%) (Overall response rate = 64.7%). No treatment-related deaths occurred. The median progression-free survival was 14.2 months (95% CI = 2.1–26.3 months); 3-year overall survival rate was 77.7%. Thus, salvage Ox-P chemotherapy for patients with relapsed or refractory MZL at the stated dosage and schedule showed moderate clinical activity and was considerable in very few selected patients (NCT01068392).

Although serum β2-microglobulin (B2M) has been suggested as a prognostic factor for several hematologic malignancies, it has not been comprehensively investigated in non-gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Between January 2000 and May 2013, a total of 174 patients with non-gastric MALT lymphoma were identified from a prospectively developed database. Baseline serum B2M was elevated in 17 (10%) patients. In univariate analysis, serum B2M ≥ 2.5 mg/L was significantly associated with progression-free survival (PFS, p < 0.001) and overall survival (OS, p < 0.001). Multivariate analysis identified serum B2M as an independent prognostic factor in PFS (hazard ratio [HR] = 3.5, 95% confidence interval [CI]: 1.2-10.0; p = 0.02) and OS (HR = 26.9, 95% CI: 2.7-269.7; p = 0.005), after adjustment for IPI and treatment modalities. Baseline serum B2M is an independent prognostic factor in patients with non-gastric MALT lymphoma. [ABSTRACT FROM AUTHOR]
