PRIMARY outcome

Timeframe: up to 5 years, 9.5 months, from first day on treatment to last follow up

Population: The study was stopped prematurely, subjects were not followed for a full 7 years. We have data for 16 subjects, 6 experienced a progression event, 10 survived progression-free through last follow-up. Date of last follow-up is used to calculate progression-free survival for those who did not experience progression.

Estimate median progression free survival (PFS), where PFS is defined as the number of days from administration of Ibritumomab tiuxetan In111 (defined as day 1) until the participant develops progressive disease or death from NHL (Non-Hodgkin's Lymphoma).

Median Progression Free Survival (PFS)
44.3 months
Interval 32.8 to 46.1

SECONDARY outcome

Timeframe: Up to 24 months

Estimate the 24 month progression free survival (PFS), where PFS is defined as the number of days from the first Ibritumomab tiuxetan administration (day 0) to the day the patient experiences an event of disease progression (or death). PFS is summarized as the percentage of patients that survived progression free after 24 months. Progression is defined as any of the following: \- Appearances of any new lesions/sites during or after therapy. * Increase of \>/= 50% in the SPD (sum of perpendicular diameter) from nadir measurement of all involved dominant lymph nodes and liver nodules and spleen nodules or unequivocal progression in any nonmeasurable disease or nondominant site. * Increase by \> 50% in greatest diameter from nadir measurement of any previously involved dominant node \> 1.0 cm in its short axis.

24-month Progression Free Survival (PFS)
11 Participants

SECONDARY outcome

Timeframe: Up to 5 years and 9.5 months

To estimate the Complete Response and unconfirmed Complete Response rate (assessing Ibritumomab tiuxetan). Complete response is defined as the complete disappearance of all detectable clinical and radiographic evidence of disease and disappearance of all disease related B-symptoms, and all dominant lymph nodes and nodal masses have regressed to normal size, and complete resolution of lymphoma in the bone marrow biopsy. Unconfirmed Complete Response (CRu) defined as the above, but with either a \> 1.5cm residual node that has decreased by \>75%, and/or individual nodes that were previously confluent that have decreased by \>75% in SPD, and/or indeterminate bone marrow (increased number or size of aggregates without cytologic or architectural atypia).
