This single arm study will evaluate the benefit of adding MabThera to standard induction chemotherapy in patients with newly diagnosed mantle cell lymphoma. The safety and tolerability of a MabThera-containing first line regimen will also be assessed. All patients will receive MabThera (375mg/m2 iv) every 3 weeks for 8 cycles, in combination with standard chemotherapy. The anticipated time on study treatment is 3-12 months, and the target sample size is \<100 individuals.

Number of Participants Achieving Complete Remission (CR) (Including Unconfirmed CR [CR(u)]) or Partial Remission (PR)
CR was defined by: a) disappearance of clinical/radiographic evidence of disease, disease-related symptoms, and biochemical abnormalities; b) decrease in lymph nodes (LNs) greater than (\>) 1.5 centimeters (cm) in greatest transverse diameter (GTD) to less than (\<) 1.5 cm, a decrease in LNs 1.1 - 1.5 cm to 1 cm or 75 percent (%) decrease in sum of the products of GTD (SPD); c) non-palpable spleen, decreased size of enlarged organs, and disappearance of nodules; and d) disappearance of bone marrow (BM) infiltrate. CR(u) was defined as fulfilling a) and c), above, with greater than or equal to (≥) 1 of the following: a) \> 75% decrease in SPD of LNs \> 1.5 cm, and \> 75% decrease in SPD of previously confluent LNs; b) indeterminate BM, or c) confirmed CR. PR was defined by: a) 50% decrease in SPD of the 6 largest LNs; b) no increase in LNs, liver, or spleen size; c) ≥ 50% decrease in splenic and hepatic nodule SPDs; d) no measurable disease in other organs; and e) no new sites of disease.
Time frame: Screening, Baseline (BL), every 21 days thereafter up to Week 27, every 3 months thereafter up to Month 24, Withdrawal Visit (4 weeks after discontinuation of study treatment)
Progression Free Survival (PFS)
PFS was defined as the median time, in months, from the date of study entry to disease progression, death due to mantle cell lymphoma, or last contact. Progressive disease (PD) was defined by: a) 50% increase from nadir in the SPD of any previously identified abnormal LN, or b) appearance of any new lesion during or at the end of treatment. The 95% confidence interval (CI) was estimated using Kaplan-Meier methodology.
Time frame: Screening, BL, every 21 days thereafter up to Week 27, every 3 months thereafter up to Month 24, Withdrawal Visit (4 weeks after discontinuation of study treatment)
Event Free Survival (EFS)
EFS was defined as the median time, in months, from the date of study entry disease progression, relapse, secondary malignancy, death or last contact. Relapse was defined by: a) appearance of any new lesion or a ≥ 50% increase in size of previously involved sites, or b) ≥ 50% increase in GTD of any previously identified LN \>1 cm in short axis or in the SPD of more than one LN. The 95% CI was estimated using Kaplan-Meier methodology.
