Rituximab Augmentation Following R-CHOP Induction Chemotherapy in Extremely Elderly Patients With Diffuse Large B Cell Lymphoma
- Registration Number
- NCT01181999
- Lead Sponsor
- Chonnam National University Hospital
- Brief Summary
Rituximab (R) plus CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) combination is considered as the new gold standard for the first-line treatment of elderly patients with diffuse large B-cell lymphoma (DLBCL).
The study is aimed to evaluate the overall response rate and the safety of four cycles of R-CHOP chemotherapy and followed by rituximab augmentation (weekly four times infusion) in newly diagnosed DLBCL patients with aged more than 70 years.
- Detailed Description
1. Four cycles of R-CHOP chemotherapy for the induction treatment \[Dose intensity of CHOP chemotherapy is modulated according to Charlson Comorbidity Index (CCI)\]
If patients with CCI \<1
* Rituximab: 375 mg/m2, day 1 every 3 weeks.
* Conventional dose of CHOP chemotherapy repeat every 3 weeks.
If patients with CCI ≥1
* Rituximab: 375 mg/m2, day 1 every 3 weeks.
* 75% of conventional CHOP repeat every 3 weeks.
2. Rituximab augmentation
* Rituximab: 375 mg/m2, every week x 4 times.
* Trimethoprim-sulfamethoxazole 1 tablet per day during augmentation

- Primary Outcome Measures
Name Time Method the overall response rate three years after the completion of rituximab augmentation To evaluate the objective overall response rate of four cycles of R-CHOP and followed by four times weekly rituximab augmentation in exteremely elderly patients with DLBCL.
