ObjectiveGynaecological cancer treatment impacts women’s physical and psychological health. Our objective was to examine quality of life (QoL) in women with advanced gynaecological cancer at diagnosis and one year later, and to identify sociodemographic and clinical characteristics associated with QoL.MethodsWomen with endometrial, ovarian or cervical cancer treated in Uppsala, Sweden 2012–2019 were included. FIGO stage ≥II was considered advanced gynaecological cancer, whereas women in FIGO stage I were used as a control group. QoL was assessed with SF-36. We obtained information on sociodemographic and clinical characteristics from medical records and health questionnaires. Differences in QoL domains were tested with t-tests, a mixed model ANOVA and multiple linear regression analyses.ResultsThe study population (n = 372) included 150 (40.3%) women with advanced gynaecological cancer. At diagnosis, women with advanced cancer reported lower physical (71.6 vs 81.8 (mean) p<0.05) and role functioning/physical scores (62.6 vs 77.2 (mean) p<0.05) than women in FIGO stage I. One year later, women with advanced cancer reported higher scores in the mental health domain (78.3 vs 73.2 (mean) p<0.05) than women in FIGO stage I. However, no difference was found in the QoL scores of women with advanced disease one year after diagnoses when stratified by diagnosis. Women with a history of psychiatric illness and higher BMI reported poorer physical and mental QoL at follow-up, while advanced stage, level of education and smoking were not associated with QoL.ConclusionWomen with advanced gynaecological cancer have equally good QoL one year after diagnosis as women with limited disease. Women with previous psychiatric illness and high BMI, are at risk of impaired physical and mental health.
