Clinical InvestigationHealth-Related Quality of Life in Cervical Cancer Survivors: A Population-Based Survey
Introduction
Cervical cancer is an important cause of death in women, especially in developing countries. In Europe, cervical cancer is diagnosed in 60,000 women annually (1). Because of improved therapies and early detection, the number of women who survive cervical cancer has increased (2). These survivors have been given a diagnosis of a life-threatening disease and were confronted with their own mortality. They may still experience the physical side effects of cervical cancer therapy, such as permanent consequences for sexual function and childbearing, as well as menopausal, urologic, and gastrointestinal symptoms (3). Survivors may also experience anxiety for recurrence of cervical cancer.
Health-related quality of life (HRQoL), defined in this study as the quality of life relating to disease and/or treatment, has been described for the 1 to 5–6 years after treatment of cervical cancer 4, 5, 6, 7, 8. In, e.g., the case of prostate cancer (9) and adult-onset cancers in general (10), long-term cancer survivors showed a comparatively favorable HRQoL, whereas HRQoL was less favorable in survivors of non-Hodgkin disease (11). However, with the exception of a recent Korean study (12), long-term HRQoL after diagnosis of cervical cancer has been described for only small numbers of patients 13, 14, 15.
The present study aims to assess the generic and treatment-specific HRQoL of women who survived cervical cancer. For this, a population-based study was conducted of all women given a diagnosis of cervical cancer in the region of the Eindhoven Cancer Registry (ECR), The Netherlands, in 1995–2003. We hypothesized that HRQoL of survivors would be similar to the general population, HRQoL would be better in long-term than short-term survivors, and adjuvant radiotherapy after surgery would be associated with worse HRQoL than primary radiotherapy.

Setting and respondents
The ECR records data for all patients with newly diagnosed cancer in the south of The Netherlands, an area with 2.3 million inhabitants, 17 hospital locations, and two large radiotherapy institutes (16). In cooperation with the ECR and all gynecologic oncology departments in the region, we conducted a population-based cross-sectional survey. All women could be identified who had cervical cancer diagnosed between Jan 1, 1995, and Dec 31, 2003 (n = 691). Women who had died could be excluded
Respondents' characteristics
Of the 421 cervical cancer survivors (response rate, 69%), 291 completed the questionnaire. The remaining 130 questionnaires were not completed because of wrong address (n = 11), patients' bad health (n = 2), lack of motivation (n = 2), death (n = 1), or unknown reasons (n = 114) (Fig. 1). Compared with the reference group, survivors were older, had a lower education level, and had lower rates of having paid jobs, partners, and children (Table 1).
Clinical data
Average age at diagnosis was 47 years (range,
Discussion
We assessed HRQoL in 291 cervical cancer survivors 2–10 years after diagnosis and treatment and found that the majority was doing well. However, cervical cancer–specific symptoms, such as pain in the abdomen, urinary leakage, and menopausal symptoms, were reported by several women and mental health was significantly worse than in the reference group. The HRQoL scores of 2–5-year survivors were similar to those of 6–10-year survivors, except for more anxiety, worse body image, and more sexual
