A sample consent form is given in Appendix I. The patient must sign the consent form prior to registration.~* Patients must be accessible for treatment and follow up. Patients registered on this trial must complete their therapy with 90Y Ibritumomab Tiuxetan at the participating centre. Induction chemotherapy with R-CHOP should also be completed at the participating centre, but exceptions can be made according to the discretion of the centre's primary investigator.~* Protocol treatment is to begin within 5 working days of patient registration~Exclusion Criteria:~* Pregnancy or women who intend to breast-feed during the study period.~* Follicular non-Hodgkin's lymphoma grade IIIb histology, according to the World Health Organization (WHO) classification.~* Known human immunodeficiency virus infection or hepatitis B viral infection.~* Life expectancy less than or equal to 3 months, according to physician judgement.~* Evidence of left ventricular (LV) dysfunction (ejection fraction less than or equal to 50%). Demonstration of LV function is required in patients over the age of 60 or in patients with a prior history of hypertension, congestive heart failure, peripheral vascular disease, cerebrovascular disease, coronary artery disease, or cardiac arrhythmia.~* Serum creatinine, alkaline phosphatase, or total bilirubin \>2.5 times the upper limit of the normal value, unless clearly related to lymphoma.~* Concurrent uncontrolled medical disease, including severe congestive heart failure, myocardial infarction within 6 months prior to enrollment, severe chronic renal failure, or active infection, with the severity of disease judged according to the discretion of the treating physician.~* Patients with a history of other malignancies, except: (1) adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or (2) other solid tumours curatively treated with no evidence of disease for \> 5 years
