Summary
This summary is machine-generated.Advanced age, male sex, and prior cancer history increase lymphoma risk after kidney transplant. Certain factors like diabetic kidney disease may reduce risk but increase mortality.
Area Of Science
- Nephrology
- Oncology
- Transplant Surgery
Background
- Non-virologic risk factors for late-onset post-transplant lymphoma (PTL) after kidney transplant (KT) are understudied.
- Understanding these factors is crucial for improving long-term outcomes in kidney transplant recipients (KTRs).
Purpose Of The Study
- To investigate non-virologic risk factors associated with PTL beyond the first year post-KT.
- To identify factors influencing both PTL and all-cause mortality in KTRs.
Main Methods
- Secondary analysis of de-identified data from 166,256 adult KTRs.
- Cause-specific Cox regressions were used to assess associations between non-virologic factors and PTL or mortality.
- Analysis focused on KTRs with conditional cancer-free survival one year post-KT.
Main Results
- Recipient age (≥65 and 50-64 years) and pretransplant cancer history were strong predictors of late-onset PTL.
- Other risk factors included alemtuzumab induction, prior KT, male sex, ECD transplant, and acute rejection.
- Native diabetic renal disease and prolonged pre-transplant dialysis were associated with decreased PTL risk but increased mortality.
Conclusions
- Advanced recipient age, male sex, prior cancer or KT, alemtuzumab induction, ECD transplant, and acute rejection are significant non-virologic risk factors for PTL.
- These findings highlight the importance of considering non-virologic factors in PTL risk stratification and patient management.
- Balancing PTL risk with overall mortality risk is essential in KTRs with specific comorbidities.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
