Abstract

Abstract only e19543 Background: Post-transplant lymphoproliferative disorder (PTLD) is a rare and potentially fatal complication of chronic immunosuppression in solid organ transplant (SOT) and hematopoietic stem cell transplant recipients. With an overall incidence of ̃ 1 percent in the transplant recipients, it is the most common malignancy, with the exception of skin cancer, after SOT in adults. There is a paucity of information concerning the outcomes and prognostic indicators of PTLD. Methods: We queried the National Cancer Database (NCDB) from 2004 – 2015 for patients with diagnosis of PTLD. Overall survival (OS) was calculated from the date of diagnosis to the date of last contact or death using Kaplan Meier curves to present the cumulative probability of survival. Additionally, Poisson regression was used to test the association between baseline variables and days to event. All statistical analyses were performed using R 4.0.3. Results: Total number of patients identified by inclusion criteria was 425. 1-year OS was 73% (CI 0.684, 0.776), 3-year OS 63% (CI 0.581, 0.683), and 5-year OS 56% (CI 0.502, 0.619) in patients with survival data available (n = 365). 263 patients were excluded due to incomplete data, yielding a final cohort of 192 patients for correlational analysis. The median age was 59 years. Majority were males (60%), < 65 year old (75.5%), Hispanics (91%), and had Charlson-Deyo Comorbidity score of 0 (63.5%). 77% were Caucasians while 15.6% were African Americans. OS was longer in males, Caucasians, patients who received radiation (versus no radiation), those treated at academic or comprehensive cancer center (versus community cancer center), had annual income > $63000 (versus < $63000) by Poisson regression analysis, however the difference was not statistically significant. Conclusions: Our data demonstrates a trend toward poor survival with socioeconomic and treatment variables including gender, race, annual income, treatment center expertise and radiation treatment. Randomized trials are needed to further assess the outcomes of PTLD.
