Study Arms:
- Bortezomib plus CHOP (Type: EXPERIMENTAL): Patients receive bortezomib IV over 3-5 seconds on days 1 and 8; doxorubicin hydrochloride IV, cyclophosphamide IV, and vincristine IV on day 1; and oral prednisolone on days 1-5.~Treatment repeats every 21 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.~Patients complete quality of life questionnaires at baseline, prior to each treatment course, and then at 30 days after completion of treatment.~After completion of study treatment, patients are followed at 30 days and then every 12 weeks thereafter.

Based on this trial design, predict the completion outcome and termination type (if applicable).
