Materials and Methods: The records of 143 patients who underwent allogeneic HSCT between 01.02.2011 and 31.12.2018 in Inonu University Turgut Özal Medical Center Department of Hematology were retrospectively reviewed. Results: In our study, late non-infectious complications were seen in 68 % of the patients. Graft Versus Host Disease (GVHD) was observed in 43 patients (33%) %. The most common GVHD involvement sites were skin and liver. It was determined that the number of CD 34 (+) cells had a significant effect on the development of chronic GVHD (p=0,01) and late stage complications (p=0,016). Chronic GVHD and late complication rates were found to be lower in the group given high CD 34 (+) cell count. When the patients were grouped according to the preparation regimens, statistically significantly more complications were observed at the rate of 78.8% in the patients in the myeloablative regimen group (p=0.005). It was observed that the rate of recurrence of the primary disease, renal complications and neurological complications was higher in the 90-120th days after transplantation. Ocular and GVHD complications were more likely to develop later. It was observed that endocrine complications were encountered equally in both early and late periods. Discussion: It was seen that, late complications were common in patients who underwent allogeneic HSCT and these complications were mostly related to GVHD and GVHD treatment.eninfo:eu-repo/semantics/openAccessArticle55210911510.5505/aot.2022.926681122821
