Acute and chronic graft versus host disease (GVHD) has a significant impact on short- and long-term morbidity as well as mortality in patients undergoing hematopoietic-cell transplantation (HCT). As a result of the physical as well as emotional aspects of the transplant process and development of GVHD, quality of life (QOL) in transplant survivors can be adversely affected. The strongest association between reduced QOL and impaired functional status following HCT is the presence of chronic GVHD. Chronic GHVD can have a negative impact on an individual's general health and mental health, and can lead to the development of functional impairments and activity limitations. In HCT survivors without chronic GVHD, self-reported QOL tends to be very similar to that in comparison groups by 1–2 years after HCT. In addition, in individuals who have been successfully treated for chronic GVHD, QOL and overall health status are not different from those with no history of chronic GVHD. These findings suggest that effective new therapies for chronic GVHD are essential, as are standardized tools for the assessment of QOL and functional outcomes in HCT survivors with chronic GVHD in order to gain a better understanding of the overall impact of the condition, as well as the effectiveness of new treatments.

Health-related quality of life after HCT

Health-related QOL (HRQL) has been fairly well studied after transplantation, but there have been several limitations to the studies that make definitive conclusions difficult to reach. First, there have been no uniform standardized QOL assessment tools or methods of analysis that have been utilized in most published data. Second, there is heterogeneity in patient populations studied such that some studies include a wide range of ages, some include recipients of both allogeneic as well as

Acute GVHD and QOL

Lee and colleagues8 studied the impact of both acute and chronic GVHD on HRQL and found that the trial outcome index (TOI) score obtained from the Functional Assessment of Cancer Therapy (FACT)-BMT survey was a sensitive indicator regarding the impact of GVHD on a patient's perceived QOL. Patients who had acute GHVD had a measurable decline in their QOL over the first 6 months after HCT compared to those with no acute GVHD who had a stable QOL. However, this adverse impact from acute GVHD did

Risk factors for adverse QOL: pediatric studies

Several studies have specifically examined the impact of HCT on QOL in children. These studies have their own limitations, particularly in the validity of parental report of QOL as a surrogate marker in younger children, and variations between studies in the length of follow-up and types of HCT performed.

To address the variance between parental versus self-report of QOL, Nuss and colleagues surveyed the child as well as the mother and father.11 This study utilized the Pediatric Quality of Life

Impact of chronic GVHD

Few studies have specifically examined the overall impact of chronic GVHD on patients after HCT. We have examined this in the Bone Marrow Transplant Survivor Study (BMT-SS), a collaborative effort between the City of Hope Cancer Center and the University of Minnesota that is examining the long-term outcomes of individuals who have survived ≥2 years after undergoing HCT. Participants of the BMT-SS included individuals who received HCT for hematologic and non-hematologic malignancies and other

Functional outcomes

While many studies have focused specifically on issues related to QOL, few have addressed the issue of overall health status and recovery in patients who have had chronic GVHD. Again from the BMT-SS, we have recently reported such an analysis to determine the impact of chronic GVHD on the overall health status of HCT recipients.17 The outcomes that were addressed in this analysis included six domains of health status that had been previously reported from the Childhood Cancer Survivor Study18,

Recovery

As seen in many studies, the majority of HCT survivors will be physically able to function well by 1 year post-HCT, but this is impacted by pre-transplant level of physical performance, family relationships, and chronic GVHD.19 However, it has been demonstrated that recovery continues beyond the first year and return to full-time work or school may still require a longer period of recovery. Most have returned to full-time school or occupations by 2 years.19

A multidisciplinary approach to the

Considerations for QOL measurement in survivors with GVHD

It has been demonstrated that patients who suffer from chronic GVHD will experience a significant negative impact on QOL and their functional status. Accurately capturing this information will be crucial to the success of future trials of chronic GVHD therapy. As mentioned previously, the use of common assessment tools will aid in the overall understanding of these issues across different studies and patient populations. Recently recommended as ‘consensus tools’ were the Medical Outcomes Study

Conclusions

Chronic GVHD is the leading cause of morbidity and mortality in HCT survivors. Management of patients with cGVHD is complex and requires a multidisciplinary approach to address the physical and psychological consequences of the disease and its treatment. Response to therapy is suboptimal, and there is an urgent need for systematic study of agents to be used as primary therapy and in the salvage setting. Such studies will be possible only if consensus can be reached regarding meaningful grading

      Reduced QoL is increasingly recognized as an important feature of GVHD and one that requires greater understanding to address the overall impact on patients.11 In observational studies, almost a third of patients, having undergone HSCT, were considered to have poor QoL, and significant differences were typically observed in patients with moderate or severe GVHD.8,12-15 Improvements in QoL have been observed over time in patients following HSCT, but only in those patients without cGVHD.16

      Elimination of patient leukemic cells, termed graft-versus-leukemia effect (GVL), is based on allo-reactive T lymphocytes present in the donor graft or infused after HSCT (donor lymphocyte infusion, DLI). However, curative GVL of allo-reactive donor lymphocytes correlates with the risk of graft-versus-host disease (GvHD), a frequent, life-threatening adverse event and the major cause of non-relapsed mortality after allo-HSCT [6]. The high risk of GvHD in allogeneic transplantation settings and the occurrence of off-target and/or on-target/off-tumor activities of otherwise tumor-specific T lymphocytes in cancer treatment have underlined the strong need for safety strategies to specifically and conditionally eliminate infused T lymphocytes.
