title: Chronic Graft Versus Host Disease in Acute Leukemia Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplant: Analysis of Risk Factors, Pattern and Long Term Outcome.
abstract: Chronic graft versus host disease (cGVHD) is a common late complication of allogenic hematopoietic stem cell transplant (HSCT). We analyzed risk factors, pattern and long term transplant outcomes of cGVHD at a tertiary cancer centre. Seventy-seven consecutive patients who underwent HSCT for acute leukemia were included. Forty (52 %) patients developed cGVHD; 24 (60 %) extensive stage while 16 (40 %) limited stage. Oral cavity was the commonest site of involvement (25 patients) followed by liver, skin and lung. We found that female donor to male recipient transplant and diagnosis of acute lymphoblastic leukemia (ALL) were the only factors associated with increased risk of cGVHD. The incidence of leukemia relapse was 18 % in patients who developed cGVHD compared to 51 % in those who did not (P = 0.002). Four year overall survival and relapse free survival (RFS) were 62 and 46 % in patients who developed cGVHD compared to 29 % (P < 0.001) and 29 % (P < 0.001) in patients who did not develop cGVHD, respectively. We conclude that cGVHD is more common in male patients with female donors and in patients transplanted for ALL. Oral cavity is the commonest site of cGVHD in our patients and transplant related survival outcomes are superior in patients who develop cGVHD.
