The median survival for aggressive non-Hodgkin's lymphomas relapsing after or refractory to high-dose therapy and autologous stem cell transplantation therapy is 6.2 months. In these cases, there is limited salvageability with the use of conventional therapy. The purpose of this retrospective analysis was to evaluate single-agent rituximab as treatment for aggressive non-Hodgkin's lymphomas in these cases.
Between January 1997 and February 2000, we treated 17 patients with aggressive non-Hodgkin's lymphomas whose disease was refractory to, or relapsed after, autologous stem cell transplantation. Treatment consisted of rituximab, 375 mg/m2 as a single agent for four weekly doses. Thirteen patients had diffuse large B-cell lymphoma, and four patients had mantle cell lymphoma. The median time from autologous stem cell transplantation to relapse was 10 months (range, 2-40 months). The median number of prior therapies, including autologous stem cell transplantation, was three (range, 2-6).
The overall response rate to rituximab was 53%, and there were four complete responses and five partial responses. Seven of 13 patients with diffuse large B-cell lymphoma (three complete responses, four partial responses) responded, and two of four patients with mantle cell lymphoma (one complete responses, one partial responses) responded. The median progression-free survival for all responders was 13 months (range, 6-18 months). Four responders (two complete responses, two partial responses) were re-treated with a second course of rituximab for disease recurrence and responded to further antibody therapy. Rituximab was well tolerated with no serious adverse events.
Rituximab is effective and well-tolerated palliative treatment for aggressive non-Hodgkin's lymphomas that relapse after or is refractory to autologous stem cell transplantation.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 February 2020.
All research outputs
#11,471,584
of 34,410,315 outputs
Outputs from Cancer Journal
#390
of 1,000 outputs
Outputs of similar age
#30,717
of 73,656 outputs
Outputs of similar age from Cancer Journal
#1
of 2 outputs
Altmetric has tracked 34,410,315 research outputs across all sources so far. This one has received more attention than most of these and is in the 65th percentile.
So far Altmetric has tracked 1,000 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.9. This one has gotten more attention than average, scoring higher than 56% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 73,656 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 57% of its contemporaries.
We're also able to compare this research output to 2 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
