Quality of life in cancer survivors compared with the general population.
e16502 Background: Assessments of quality of life (QOL) among cancer survivors have had mixed results. Literature suggests that those treated with cranial irradiation (CNS) or stem cell transplantation (SCT) have a poorer quality of life. Methods: 309 cancer survivors (37 adult and 241 childhood malignancies, 31 SCT survivors) completed the Medical Outcomes Study 36-Item Short Form Healthy Survey (MOS SF-36). Demographic, disease and treatment characteristics were assessed and inter-group heterogeneity tested across three survivor groups (F-test for age; chi-square for disease and treatment characteristics). Aggregate data analysis for SF-36 composite and norm-based scoring measures was undertaken by using the mixed effect model with unequal random effect variances across studies. Treatment characteristics included age at diagnosis, current age, site of disease [cranial (y/n)], chemotherapy (y/n), radiation therapy (y/n), SCT with/without total body irradiation (TBI). All statistical tests were two-sided, P-values < 0.05 considered statistically significant. Results: The mean age at assessment was 33.4 years. 255 (83.9%) received chemotherapy, 187 (60.7%) radiation, 49 (15.9%) underwent SCT. Among those irradiated, 28 (9.1%) had TBI and 62 (20.1%) had CNS irradiation. The MOS SF-36 physical composite score was 50.5 (9.5-73.3) and mental health composite score was 50.2 (9.2-55.9). Pooled results for the MOS SF-36 included: bodily pain 51.9 (19.9-62.1), general health perceptions 46.7 18.6-63.9), mental health 50.6 (16.2-64.1, physical functioning 51.0 (14.9-57.0), role emotion 50.2 (9.2-55.9), role physical 50.2 (17.7-56.9), social functioning 49.5 (13.2-56.9) and vitality 51.9 (20.9-70.8). No significant variation from the general population median normative values (50.0) was identified, including those treated with CNS and SCT. There was no difference in QOL amongst those treated as children, young adults (ages 15-30 years) or adults. Role physical declined significantly with advancing age (p=0.02). Conclusions: In spite of the chronic conditions prevalent among cancer survivors, the overall QOL of most cancer survivors, including those who have received CNS or SCT, is comparable to that of the general population.
