Aims And BackgroundAlthough the long-term survival of cancer patients has risen during the last decades, little is known about their quality of life. Assessment of the long-term effect of disease and treatments on subjective qualitative aspects of life that are related to health may be important for identifying specific long-term sequelae of cancer and treatments. In order to better understand the outcomes on a long-term survivor population, a sample of breast and colon cancer patients was evaluated using state-of-the-art health-related quality of life (HRQoL) approaches and instrumentsPatients And MethodsEORTC OLQ-C30 and SF-36 HS questionnaires were mailed to a sample of subjects with a diagnosis of breast or colon cancer recruited in two randomized clinical trials with a median follow-up of 65 and 100 months, respectively. Data obtained with the SF-36 HS questionnaire were compared with data from a representative sample of the Italian population, whereas the EORTC QLQ-C30 data were evaluated across relevant subgroups.ResultsOut of 2208 subjects, 1772 were randomized to receive the different types of questionnaires and 921 answered (52%). According to the findings, if no serious comorbidity or relapse appeared, long-term cancer survivors reported having a substantially satisfying HRQoL, not much different from (age and sex) comparable controls. The most intriguing findings were those obtained from breast cancer patients. They reported a somewhat higher level than comparable Italian women of limitations in activities, when describing their role, as due to physical problems. In addition, breast cancer patients also reported lower scores (worse health perception) in two EORTC scales describing activities of daily living than colon cancer patients. When data were plotted according to the type of medical therapy, hormone therapy versus chemotherapy, a higher HRQoL was reported by the former than the latter group.ConclusionsOur study supports the hypotheses that the impact of cancer on quality of life over a period of time is not necessarily devastating in survivors. As regards the impact of different medical strategies, although our data are consistent with other research supporting the hypotheses that hormone therapy does not cause a decrease in long-term quality of life, differences we observed between hormone and chemotherapy might be caused by the action of confounds we were not able to control for or by the distortion introduced by the design of the present study.
