Genitourinary disease risks among ovarian cancer survivors in a population-based cohort study

While genitourinary complications during treatment for ovarian cancer are well-known, long-term adverse outcomes have not been well characterized. The number of ovarian cancer survivors has been increasing. The aim of this study was to investigate long-term adverse genitourinary outcomes in a population-based cohort. We identified a cohort of 1270 ovarian cancer survivors diagnosed between 1996 and 2012 from the Utah Cancer Registry, and 5286 cancer-free women were matched on birth year and state from the Utah Population Database. Genitourinary disease diagnoses were identified through ICD-9 codes from electronic medical records and statewide healthcare facilities data. Cox proportional hazards models were used to estimate hazard ratios (HR) for genitourinary outcomes at 1 to <5 years and 5+ years after ovarian cancer diagnosis. Ovarian cancer survivors had increased risks for urinary system disorders (HR: 2.53, 95% CI: 2.12-3.01) and genital organ disorders (HR: 1.88, 95% CI: 1.57-2.27) between 1 and <5 years after cancer diagnosis compared to the general population cohort. Increased risks were observed for acute renal failure, chronic kidney disease, calculus of kidney, hydronephrosis, pelvic peritoneal adhesions, and pelvic organ inflammatory conditions. Increased risks of several of these diseases were observed 5+ years after cancer diagnosis. Ovarian cancer survivors experience increased risks of various genitourinary diseases compared to women in the general population in the long-term. Understanding the multimorbidity trajectory among ovarian cancer survivors is important to improve clinical care after cancer treatment is completed.

Mental health disorders among ovarian cancer survivors in a population‐based cohort

AbstractBackgroundOvarian cancer is the fifth most common female cancer in the United States. There have been very few studies investigating mental health diagnoses among ovarian cancer survivors with long‐term follow up. The aim of this study is to examine the incidence of mental illness among ovarian cancer survivors compared to a general population cohort. A secondary aim is to investigate risk factors for mental illnesses among ovarian cancer survivors.Patients and methodsCohorts of 1689 ovarian cancer patients diagnosed between 1996 and 2012 and 7038 women without cancer matched by age and birth state from the general population were identified. Mental health diagnoses were identified from electronic medical records and statewide healthcare facilities data. Cox proportional hazard models were used to estimate hazard ratios (HRs).ResultsOvarian cancer survivors experienced increased risks of mental illnesses within the first 2 years after cancer diagnosis (HR = 3.55, 95% CI = 3.04–4.14). The risks of depression among ovarian cancer survivors were nearly 3‐fold within the first 2 years of cancer diagnosis (HR = 2.59, 95% CI = 1.94–3.47), and 1.69‐fold at 2–5 years after cancer diagnosis (HR = 1.69, 95% CI = 1.18–2.42). Ovarian cancer survivors experienced an 80% increased risk of death with a mental illness diagnosis (HR = 1.80, 95% CI = 1.48–2.18) and a 94% increased risk of death with a depression diagnosis (HR = 1.94, 95% CI = 1.56–2.40).ConclusionsHigher risks of mental illnesses were observed among ovarian cancer survivors throughout the follow‐up periods of 0–2 years and 2–5 years after cancer diagnosis. Multidisciplinary care is needed to monitor and treat mental illnesses among ovarian cancer survivors.
