Cancer‐and‐treatment–specific distress and its impact on posttraumatic stress in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT)
2017
Background
In this prospective multicenter study, we investigated cancer-and-treatment–specific distress (CTXD) and its impact on symptoms of posttraumatic stress disorder (PTSD) in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT).
Methods
Patients were consulted before (T0, N = 239), 3 (T1, N = 150), and 12 months (T2, N = 102) after HSCT. Medical (eg, diagnosis and pretreatment) and demographic information, CTXD and PTSD (PCL-C) were assessed.
Results
Random intercept models revealed that the sum score of CTXD was highest pre-HSCT (T0), decreased by T1 (γ = −.18, 95% CI [−.26/−.09]), and by T2 (γ = −.10, 95% CI [−.20/−.00]). Uncertainty, family strain, and health burden were rated most distressing during HSCT. Uncertainty and family strain decreased from T0 to T1 (γ = −.30, 95% CI [−.42/−.17]; γ = −.10, 95% CI [−.20/−.00]) and health burden from T1 to T2 (γ = −.21, 95% CI [−.36/.05]). Women were more likely to report uncertainty (γ = .38, 95% CI [.19/.58]), family strain (γ = .38, 95% CI [.19/.58]), and concerns regarding appearance and sexuality (γ = .31, 95% CI [.14/.47]) than men. Uncertainty (γ = .18, 95% CI [.12/.24]), appearance and sexuality (γ = .09, 95% CI [.01/.16]), and health burden (γ = .21, 95% CI [.14/.27]) emerged as predictors of PTSD symptomatology across the 3 assessment points.
Conclusions
Our data provide first evidence regarding the course of 6 dimensions of CTXD during HSCT and their impact on PTSD symptomatology. Specifically, results emphasize the major burden of uncertainty pre-HSCT and the impact of uncertainty and concerns regarding appearance and sexuality on PTSD symptomatology.
