Allogenic Stem Cell Transplant In Patients Over The Age Of 70, Including Octogenarians, With Hematologic Malignancies: A Single Institution Experience.

e18538 Background: Patient age is an important factor when considering allogenic stem cell transplant (aSCT) as a treatment modality for hematologic malignancies. Previous series exploring older age and outcome in aSCT have generally not included fit, older adults beyond the age of 80: a group typically considered ineligible for aSCT. This report describes our single-institution experience with aSCT in patients age 70 and older, including octogenarians, from March 2010 through April 2016. Methods: Retrospective analysis was performed on all patients older than 70 years undergoing aSCT at UMass Memorial Medical Center (UMMMC) between March 2010 and April 2016. The study was approved by the UMMMC IRB. Results: 32 patients were identified: 19 men and 13 women. 1 patient underwent a second aSCT in the study period. Median age at time of aSCT was 73 years (range 70-83). 4 patients were age >80. Diseases treated were AML (19 pts.), MDS (12 pts.), and CLL (1 pt.). 24 transplants were performed with unrelated donors: 17 with 10/10 match, 3 with 11/12 match, 3 with 10/12 match, and 1 with 9/12 match. 9 were performed with umbilical cord blood units. Grade II-IV acute GVHD developed in 9 patients (27%). Day 100 survival by age following the transplant were 11/18 (61%) for patients aged 70-75, 6/10 (60%) for patients aged 75-80 and 4/4 (100%) for patients aged 80-85. Conclusions: Allogenic Stem Cell Transplant is a viable treatment modality in highly-selected elderly patients with hematologic malignancies. Further studies are warranted in a prospective fashion.
