INTRODUCTION
Modern oncology advances have resulted in improved survival
rates for most cancers, with childhood cancer demonstrating one of
the most dramatic improvements [1]. The overall survival rate for
childhood cancer is now approximately 75% [2]. We are cautioned,
however, that even after cure, cancer can be a ‘‘chronic condition’’
[3]. Specifically, two-thirds of survivors can be expected to
experience at least one late effect that may impair quality of life,
while as many as one-quarter experience a severe or life-threatening
late effect [4]. Subsequently, survivors of childhood cancer, their
families, and medical providers are obliged to continue appropriate
surveillance of the survivors’ health based on their expected risks
[5]. While the structure and process of transitioning survivors
who have turned adult age to appropriate care facilities remains
problematic, pediatric cancer centers increasingly establish pro-
grams for post-treatment clinical follow-up [6,7].
Long-term survivorship programs have a unique opportunity to
investigate the impact of cancer and its treatment on survivors across
the developmental span. Some investigators suggest that research
objectives should be a major component of such programs, as data
from longitudinal clinical follow-up are expected to inform
clinicians about long-term risk-benefit ratios of newer treatments
[5,8].
Although still not without selection bias, standardized health-
related quality of life (HRQOL) measures administered during
routine follow-up visits may capture a broader range of participants
relative to mailed survey questionnaires, a common sampling
method utilized in survivorship research studies [9]. For example,
ethnic minority populations traditionally have lower response rates
to mailed surveys [10] and subsequently are underrepresented in
such studies [9]. Given the disparities in health outcomes between
Caucasians and minority groups [1], it cannot be assumed that
HRQOL outcomes are equal among ethnic groups and this issue
warrants empirical investigation.
Approximately 60% of the patient population at the cancer
center at which this study was conducted identify themselves as
Hispanic. Given this ethnic make up, we anticipated the ability to
represent the Hispanic survivors in our HRQOL data, and to
evaluate potential group differences in outcomes. The purpose of
this study was to describe HRQOL in pediatric cancer survivors
attending a long-term follow-up clinic and to identify demographic
and disease/treatment-related factors associated with poor quality of
life outcomes.
METHODS
Subjects
English and Spanish-speaking pediatric cancer survivors, age 8–
18 years of age, who attended the long-term information, follow-up,
and evaluation (LIFE) clinic at CHLA between January 1, 2002 and
December 31, 2002 were eligible for this study. Participants were
required to be cancer free, at least 5 years from diagnosis and off-
treatment for a minimum of 2 years. Using clinic rosters, we
Background. Childhood cancer survivors are at risk for lateeffects of disease and treatment that may be attributed to multiplecauses. This study describes health-related quality of life (HRQOL) inchildhood cancer survivors and identifies factors related to poorquality of life outcomes. Procedure. Patients age 8–18 years, whoattended the long-term information, follow-up, and evaluation (LIFE)clinic at Childrens Hospital Los Angeles during a 1-year time-periodwere eligible for the study. Eighty-six survivors (mean time off-treatment¼7.8 years) completed the Pediatric Quality of LifeInventory 4.0 Generic Core Scales, a LIFE Clinic Intake Question-naire and rated their fatigue using a 10-point scale. Oncology nursesindependently rated subjects’ late effects using a 3-point severityscale. Linear regression procedures were used to evaluate theassociation between demographic and medical factors and HRQOL.
Results. Fatigue and more severe late effects were associated withpoorer physical functioning (fatigue, P<0.02; late effects, P<0.01).Fatigue, ethnic minority status, and a brain tumor diagnosiswere associated with poorer psychosocial functioning (fatigue,P<0.0001; minority status, P<0.04; brain tumor, P<0.01). Fatiguewas the only factor related to both poor physical and psychosocialHRQOL. Conclusions. Long-term follow-up clinics for childhoodcancer survivors are in a unique position to monitor HRQOL overtime. Factors associated with poorer HRQOL include fatigue, ethnicminority status, a brain tumor diagnosis, and more severe late effects.Future studies need to clarify relationships between ethnicity,socioeconomic status (SES), and HRQOL in cancer survivors.

(73%) eligible for this study. The Institutional Review Board at
CHLA approved all study procedures, including a waiver of
informed consent, in accordance with requirements established by
the US Department of Health and Human Services.
Questionnaire Data
In this retrospective study, we analyzed questionnaire and
clinical data that were collected during the child’s annual clinic visit.
1. The LIFE Clinic Intake Questionnaire, developed by the
clinicians in the LIFE program, collects demographic and
health status information. The questionnaire includes a single
item from the SF-36 scale [11] that asks the child to rate his/her
‘‘overall health’’ status as excellent, good, fair, or poor. Two
additional items, adapted from the National Comprehensive
Cancer Network clinical practice guidelines, ask the child to
rate his/her fatigue over the past 4 weeks and current level of
pain using a 0–10 analog scale (0¼ no pain/no fatigue;
10¼most pain ever/most fatigue ever) [12].
2. The PedsQLTM 4.0 Generic Core Scales assess HRQOL,
including physical (eight items), emotional (five items), social
(five items), and school functioning (five items) [13]. The
PedsQLTM Psychosocial Summary Scale contains the emo-
tional, social and school functioning subscales while the
physical summary scale contains the physical subscale. The
child uses a 5-point Likert scale to rate how much of a problem
each item has been for him/her over the past 7 days (0¼ never a
problem to 4¼ almost always a problem). Responses are
reverse-scored and linearly transformed to a 0–100 scale, with
higher scores indicating better HRQOL.
The PedsQLTM 4.0 Generic Core Scales have been tested with
pediatric oncology patients, including Spanish-speaking samples,
and have demonstrated strong internal consistency, reliability, and
validity [14]. The Cronbach alpha coefficient in this study was 0.91
for the full scale, 0.82 for the physical functioning scale, and 0.88 for
the psychosocial functioning scale. Patients completed a devel-
opmentally appropriate (child 8–12 years; adolescent 13–18 years)
English or Spanish version of the PedsQLTM.
Clinical Data
A research assistant extracted the following information from
each child’s medical record: diagnosis, date of diagnosis, date of last
cancer treatment, a summary of cancer treatment, and a list of
disease/treatment-related late effects.
The Late Effect Severity Scale, developed by experts in the area
of childhood survivorship [15] uses a 3-point scale to rate severity of
late effects. Severity ratings are defined as follows: 1¼ no limitation
of activity, requires no special medical attention, no cosmetic
differences apparent (e.g., no medical late effects, slight scarring
post-biopsy); 2¼mild restriction of daily activity, mild cosmetic
changes, some medical attention or equipment required (e.g.,
hypothyroidism, abnormally short stature); or 3¼ significant
restriction on daily activity, significant cosmetic changes, signifi-
cant medical attention or equipment needed (e.g., cardiomyopathy,
gonadal failure). Two pediatric advanced-practice oncology nurses
independently reviewed the survivors’ medical records and scored
the severity of their late effects using this scale. The nurses reviewed
medical records together to resolve any discrepancies in scores.
Analyses
Using the National Comprehensive Cancer Network clinical
practice guidelines, we classified survivors with a fatigue score of 4
or higher as fatigued and coded those with a pain score of 4 or higher
as having ‘‘moderate to severe’’ levels of pain [12]. Analog fatigue
and pain scores were transformed into categorical variables.
Adequate response equivalence has been demonstrated for the
PedsQLTM Core Scales in English and Spanish; therefore we
combined these data [14].
Descriptive statistics (means, standard deviations, and frequen-
cies) were calculated for all variables. The outcome variables in this
study were the PedsQLTM total score, the physical functioning
score, and the psychosocial functioning score, which includes the
social, school, and emotional subscales. Linear regression proce-
dures were used to evaluate the association between demographic
and medical/treatment factors and HRQOL outcomes [16]. Multi-
variate regression procedures were used to develop a multivariate
model for the outcome variables. Tests of linear trend were
calculated by fitting a variable representing ordinal categories of
increasing exposure in the regression models [17]. All statistical
testing used an alpha of 0.05 (two-tailed). All data analyses were
conducted using SAS (Version 9.0).
RESULTS
Subjects
Participants included 51 males and 35 females, ranging in age
from 8 to 18 years (Table I). Forty-one of the 86 participants (48%)
were Hispanic. Twenty-two (26%) identified Spanish as the primary
language spoken in their home.
The child’s average age at diagnosis was 4 years. The vast
majority of the survivors had been off-treatment for 5–10 years.
Ninety-two percent rated their ‘‘overall health’’status as excellent or
good. Eighteen percent of the survivors reported fatigue; 9%
reported moderate to severe levels of pain. One-third of the patients
had seen a physician outside the cancer center in the past year. Sixty
percent experienced moderate to severe treatment-related late
effects. When we compared the 86 survivors in this report to the 32
survivors who attended the LIFE clinic but did not complete the
PedsQLTM forms (non-participants), we found that non-participants
were off-treatment longer than participants (mean time off-
treatment: participants¼ 7.8 years; non-participants¼ 9 years,
P-value¼ 0.03). Participants and non-participants did not differ
significantly on age at evaluation, ethnicity, diagnosis, age at
diagnosis, treatment, severity of late effects, ‘‘overall health’’ status,
pain, fatigue, or the frequency of doctor visits over the past year.
HRQOL in Cancer Survivors
Survivors’ PedsQLTM total, physical, and psychosocial func-
tioning mean scores were not significantly different than those
reported for healthy children (Table II) [14]. We found a positive
correlation between the survivors’ PedsQLTM total, physical, and
psychosocial functioning mean scores and their ‘‘overall health’’
status rating (r¼ 0.40–0.45).
Pediatr Blood Cancer DOI 10.1002/pbc
HRQOL in Pediatric Cancer Survivors 299
Univariate Analyses
PedsQLTM total, physical, and psychosocial functioning scores
were significantly lower (poorer HRQOL) for patients diagnosed
with a brain tumor (Table III). HRQOL scores also were signi-
ficantly lower for patients reporting fatigue, pain, or for those with
more severe late effects. Hispanic ethnicity was associated with
significantly lower PedsQLTM total and psychosocial functioning
scores. PedsQLTM physical functioning scores were significantly
lower for the survivors who had seen a doctor in the past year. Type
of treatment, time off-treatment, primary language spoken in the
home, and the subject’s current age were not related to PedsQLTM
total, physical, or psychosocial HRQOL scores.
Multivariate Analyses
In the final multivariate models, fatigue was associated with poor
QOL, including poorer physical and psychosocial functioning
(Table IV). A higher score on the late effects severity scale,
indicating more severe late effects, was significantly correlated with
poorer physical functioning but not with poorer psychosocial
functioning. A brain tumor diagnosis and non-Caucasian ethnicity
were associated with poorer psychosocial functioning.
With the PedsQLTM psychosocial subscales (Table V), we found
that fatigued survivors reported significantly poorer social, school,
and emotional functioning than the non-fatigued survivors
(Fig. 1). Interestingly, the non-fatigued survivors’ mean psychoso-
cial subscale scores were comparable to the mean scores for healthy
children. Brain tumor survivors scored significantly lower on the
PedsQLTM social functioning scale (indicating more problems) than
survivors of other cancers.
We found an association between ethnicity and several of the
psychosocial subscales. PedsQLTM school scores were significantly
lower (indicating more problems) for the Hispanic and non-
Caucasian survivors compared to the Caucasian survivors (Hispanic
survivors’ P-value¼ 0.0001 and other non-Caucasian survivors’
P-value¼ 0.001). PedsQLTM emotional functioning scores were
significantly lower for Hispanic survivors compared to non-
Hispanic survivors. Although the differences between the ethnic
groups were not significant for social functioning, PedsQLTM social
scores were lowest for the Hispanic survivors.

HRQOL in Pediatric Cancer Survivors 301
DISCUSSION
Our finding that HRQOL scores for most pediatric cancer
survivors were similar to those reported for healthy children is
consistent with other published reports [18–21] and very encourag-
ing in light of the increasing numbers of children surviving cancer.
At the same time, there were higher risk subgroups within our clinic
sample.
While relatively few survivors in this study were fatigued, the
survivors who were fatigued experienced significantly poorer
physical, social, emotional, and school functioning than those
who were not fatigued. Although the underlying mechanisms of
persistent fatigue following cancer treatment are poorly understood
in pediatric and adult cancer survivors, studies consistently report a
negative relationship between fatigue and HRQOL [22–25].
Fatigue can have a negative impact on physical activity, mood,
memory/cognition, school performance, and socialization. In this
study, fatigue was the most powerful predictor of functional status
and HRQOL; a single self-report fatigue question was very effective
in the screening and identification of high-risk patients in the clinical
setting. Despite our limited understanding of post-treatment fatigue
there is sufficient data to warrant routine fatigue screening during
long-term follow-up. In cases of a positive fatigue screen, a more
comprehensive work-up should be conducted to identify and treat
underlying contributors toward the individual patient’s fatigue [12].
Consistent with other reports, the majority of the survivors in
this study experienced moderate to severe late effects [4]. While
increased severity of late effects was associated with a decrease in
physical functioning, there was no direct association between
severity of late effects and psychosocial functioning. Psychosocial
functioning tends to reflect the survivor’s subjective interpretation
of the cancer experience [26]; often, surviving cancer results in
a positive reassessment of life that does not match health status
[27–29].
Another possible explanation for this disparity is that the
participants in this study, who are all under the age of 18, may not
fully appreciate the long-term consequences of late effects on future
health [30]. For example, the full impact of gonadal failure, the
inability to conceive children, and lifelong dependence upon
artificial hormones, may not be fully appreciated until adulthood.
Similarly, the consequences of cognitive impairment on future
employment and socioeconomic potential are often not realized
until later in life [26]. Longitudinal studies with serial assessments
of HRQOL are needed to understand how developmental age

mediates appraisal and influences childhood cancer survivors’
emotional responses to treatment-related late effects.
The significant difference in psychosocial health outcomes
between Hispanic and Caucasian respondents in this study is, to our
knowledge, a new finding in the area of childhood cancer
survivorship. Ethnic disparities have been observed in studies of
health status among adult-onset cancer patients [31], with similar
emerging research in childhood cancer [32]; however, little is
known about ethnic or racial differences in HRQOL outcomes
among childhood cancer survivors. Since ethnic minorities
constitute a significant portion of the low socioeconomic status
(SES) groups in this country [33], it is possible that SES, and not
Hispanic ethnicity itself, accounts for the HRQOL differences in our
sample. Specifically, low-income Hispanic families may experience
greater stress in their daily lives [34], and our finding of lower
psychosocial health scores among Hispanic survivors may reflect
pre-morbid status. It is also possible that the cancer experience has
an additive impact on pre-existing SES-related stress. Additionally,
differences in cultural norms and values between ethnic groups
also must be considered as there may be differences in emotional
endorsement and reporting styles for psychosocial health [35].
To better isolate the various respective influences, it will be
necessary to compare psychosocial HRQOL outcomes in Hispanic
cancer survivors to their healthy Hispanic counterparts. A recent
study of race/ethnicity influences on outcomes in the Childhood
Cancer Survivor Study (CCSS) found that adverse outcomes
were not associated with minority status when adjusted for SES;
in fact, black survivors were less likely to report adverse mental
health [36].
Our analysis found that the ethnic differences in psychosocial
health were most prominent in the area of school functioning.
Again, this difference may not reflect cancer-related influences,
especially given the reports of higher school drop out rates and
overrepresentation of Hispanics in special education programs [37].
School difficulties in the healthy Hispanic population may relate to a
number of factors, including limited resources. Barriers to critical
knowledge and resources may have an even more detrimental
consequence in the case of childhood cancer survivors, where
the risk of learning difficulties increases the need for effective
educational advocacy by parents.
Based on our results, long-term survivors of pediatric brain
tumors are another group that are at high-risk for poorer psycho-
social HRQOL. This result is not surprising considering their
increased risk for neurocognitive, behavioral, and social impair-
ments, usually secondary to neurocognitive injury [38–41].
A limitation of our study was the inability to evaluate any
associations of family SES on the ethnicity-based HRQOL differ-
ences detected in our sample. Predominant language spoken at
home, used as a proxy estimate of SES, was not a discriminating
factor in this sample. Future studies should use more precise
measures of SES to better understand interactions between
ethnicity, other sociodemographic factors, and HRQOL outcomes
in childhood cancer survivors. A methodology that relies on
obtaining survivors’ HRQOL information during their visit may not
be generalized beyond the population of survivors attending such
clinics. Many studies of childhood cancer survivors, including this
one, are limited by single assessment in a cross-sectional sample, yet
HRQOL outcomes likely are dynamic and may fluctuate across the

lifespan. While the consideration of limited generalizability of
results is important, empirical evaluation of survivors attending
long-term follow-up clinics allows repeated standardized measures
collected from the same individuals across time, providing critical
longitudinal research and clinical data as late effects increasingly
manifest or even resolve.
The focus of long-term clinics for survivors of childhood cancer
traditionally has been to monitor and treat the physical late effects
caused by cancer and its treatment. Yet the presence of physical late
effects is only one aspect of the cancer experience thought to affect
HRQOL. Family dynamics are often forever changed, and lingering
anxiety about future health and possibility of relapse or second
malignancy may color outlook on life. Routine administration of
standardized HRQOL measures in a clinic setting may provide a
time-efficient method of easily screening and detecting the need for
more detailed assessment and intervention. Results from a recent
survey of 1,020 cancer survivors revealed nearly half felt their non-
medical needs, including practical and emotional issues, were
unmet by health care providers [42]. A review of the patient’s
responses on HRQOL measures will prompt the clinician to further
query and address potentially problematic areas. Childhood cancer
survivors cannot obtain optimal health until a comprehensive
approach addresses their psychosocial needs as well as their
physical needs.
