The purpose of this study is to evaluate risk factors for infusion-related reaction (IRR) following rituximab administration in patients with B cell non-Hodgkin lymphoma.
A retrospective analysis was conducted of patients with newly diagnosed B cell lymphoma who have received rituximab-included immunochemotherapy with appropriate premedication and commonly used schedule of infusion rate. IRRs were graded by review of the patients' electronic medical record according to the Common Terminology Criteria for Adverse Events version 4.0.
One hundred and sixty-nine patients were included in the analysis and most of the patients (150; 88.8 %) had diffuse large B cell lymphoma (DLBCL). Thirty-six patients (21.3 %) had any grade of IRRs: 23 patients were grade (G) 1 (13.6 %), 13 had ≥G2 IRRs (7.7 %), and only 4 had ≥G3 IRRs (2.4 %). All except one patient had IRR during the first cycle and only two had repetitive IRR thereafter. Bone marrow (BM) involvement was the strongest risk factor for IRR in multivariable analysis (odds ratio 4.06, 95 % confidence interval 1.67-9.89; p = 0.002). A subgroup analysis confined to patients with DLBCL showed very similar results when compared with the entire population, and patients with DLBCL who had ≥G2 IRR showed shorter event-free and overall survival when compared to those who did not.
BM involvement is predictive of occurrence of IRR during rituximab administration in patients with B cell lymphoma. More intensive premedication and careful observation for IRR during rituximab administration are required for patients with B cell lymphoma who have BM involvement.
Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am.
Very much believe in "Sing your own song - weave your own tapestry"
Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow.
Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue.
Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet.
Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys.
Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
