Abstract
PURPOSE: Gynaecological cancer patients treated with external radiation therapy to the pelvis may face long-lasting and long-term gastrointestinal syndromes. The aim of this study was to assess the association between such radiation-induced survivorship syndromes and disability pension among gynaecological cancer survivors treated with pelvic radiation therapy. METHODS: This prospective register study included gynaecological cancer survivors (n=247) treated during 1991-2003, alive at the time of the study, and <65 years of age. In 2006, they completed a postal questionnaire measuring patient-reported outcomes. The self-reported data were linked to the national register on disability pensions. Relative risks and risk differences with 95% confidence intervals (CIs) of being granted a disability pension were estimated using log-binomial regression. RESULTS: Gynaecological cancer survivors with gastrointestinal syndromes had a higher risk of disability pension than survivors without such syndromes. Survivors with blood discharge syndrome had a 2.0 (95% CI 1.3-3.2) times higher risk of disability pension than survivors without blood discharge syndrome. The relative risk among survivors with urgency syndrome was 1.9 (1.3-2.9) and for leakage syndrome, 2.1 (1.4-3.1). Adjusting for age did not affect our interpretation of the results. CONCLUSIONS: Gynaecological cancer survivors with a specific radiation-induced survivorship syndrome have a higher risk of disability pension than survivors without that specific syndrome. IMPLICATIONS FOR CANCER SURVIVORS: The findings highlight the need for more awareness and knowledge regarding the potential role of radiation-induced survivorship syndromes for continuing work among gynaecological cancer survivors. Work-life-related parameters should be considered during radiotherapy and rehabilitation after treatment.
