About this study

Official title: Identification of Clinical, Functional and Biological Predictors of Cognitive Decline and deliRium in Older Women Affected by Ovarian caNcer: the C.R.O.W.N. Study

Cognitive decline and delirium are common geriatric syndromes that adversely affect treatment adherence, functional independence, quality of life, and survival in older adults with cancer. Women aged 70 years and older with ovarian cancer are particularly vulnerable because of the combined effects of aging, frailty, multimorbidity, and cancer-related factors. However, the prevalence, incidence, determinants, and longitudinal trajectories of cognitive impairment and delirium in this population remain poorly characterized, and validated strategies for risk stratification are lacking.

The C.R.O.W.N. (Identification of clinical, functional and biological predictors of Cognitive decline and deliRium in Older Women affected by ovarian caNcer) study is a prospective, single-center, longitudinal observational cohort study designed to identify clinical, functional, and biological predictors of cognitive decline and delirium in older women with ovarian cancer undergoing active treatment. Women aged 70 years or older with newly diagnosed ovarian cancer or first relapse will undergo a comprehensive geriatric assessment before treatment initiation and will be followed for 12 months. Assessments will include standardized cognitive and neuropsychological testing, frailty and functional evaluation, quality-of-life assessment, and systematic delirium screening during hospitalizations. Blood samples will be collected at baseline to measure biomarkers of neurodegeneration and inflammation. Telemonitoring will complement in-person follow-up visits to improve retention and longitudinal assessment.

The primary objective is to evaluate the prevalence, incidence, and trajectory of cognitive decline and to identify its clinical, functional, and biological predictors. Secondary objectives include evaluating the occurrence and predictors of delirium, assessing the impact of cognitive disorders on disability, hospitalization, mortality, and quality of life, and developing an integrated risk prediction model combining geriatric assessment and blood-based biomarkers. The study aims to improve early identification of patients at high risk for adverse cognitive outcomes and support personalized oncogeriatric care pathways.

Read the detailed description

Cognitive decline and delirium are frequent and clinically relevant geriatric syndromes among older adults with cancer. These conditions are associated with reduced treatment adherence, functional decline, poorer quality of life, increased hospitalization, and mortality. In older women with ovarian cancer, cognitive outcomes are influenced by a complex interaction between aging-related vulnerability, frailty, multimorbidity, cancer characteristics, and oncological treatments. Despite the increasing use of Comprehensive Geriatric Assessment (CGA) in oncology, important gaps remain in identifying patients at highest risk for cognitive decline and delirium and in understanding the biological mechanisms underlying these conditions.

The C.R.O.W.N. (Identification of clinical, functional and biological predictors of Cognitive decline and deliRium in Older Women affected by ovarian caNcer) study is a prospective, longitudinal, single-center observational cohort study designed to identify clinical, functional, and biological predictors of cognitive decline and delirium in older women with ovarian cancer undergoing active treatment.

Women aged 70 years or older with newly diagnosed ovarian cancer, regardless of disease stage, or with first disease recurrence will be enrolled before the initiation of any oncological treatment or invasive procedure. All participants will undergo a standardized Comprehensive Geriatric Assessment, including evaluation of comorbidities, medications, frailty, nutritional status, physical performance, disability, mood, quality of life, and cognitive function.

Cognitive assessment will combine subjective and objective measures. Standardized neuropsychological tests will evaluate memory, executive function, attention, verbal fluency, and global cognition, while validated patient-reported outcome measures will assess perceived cognitive impairment. Participants will undergo evaluations at baseline, 6 months, and 12 months to characterize longitudinal cognitive trajectories.

During hospital admissions, including postoperative hospitalization, participants will be systematically screened for delirium using validated assessment tools. In addition, a structured telemonitoring program based on telephone contacts, video consultations when necessary, and remote cognitive screening will support follow-up, minimize missing data, and facilitate early identification of cognitive changes.

Blood samples collected before treatment initiation will be analyzed to measure biomarkers of neurodegeneration and systemic inflammation, including neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), phosphorylated tau, amyloid-beta peptides, inflammatory cytokines, C-reactive protein, and other laboratory markers. These biomarkers will be integrated with clinical and geriatric assessment data to investigate their contribution to cognitive decline and delirium.

The primary objective is to determine the prevalence and incidence of cognitive decline and to identify clinical, functional, and biological predictors associated with longitudinal cognitive deterioration. Secondary objectives include evaluating the incidence and predictors of delirium, assessing the association of cognitive disorders with disability, hospitalization, mortality, and quality of life, and developing a multivariable risk prediction model capable of stratifying patients according to their probability of adverse cognitive outcomes.

By integrating comprehensive geriatric assessment with blood-based biomarkers and longitudinal follow-up, the C.R.O.W.N. study aims to improve the early identification of vulnerable older women with ovarian cancer, support individualized oncogeriatric care, and provide evidence to inform future preventive and therapeutic strategies targeting cancer-related cognitive impairment and delirium.

Study groupRoleWhat they receive
Older Women With Ovarian CancerWomen aged 70 years or older with newly diagnosed ovarian cancer (any stage) or first disease recurrence, enrolled before initiation of any cancer treatment or invasive procedure. Participants will undergo comprehensive geriatric assessment, cognitive and functional evaluations, delirium screening during hospitalization, blood biomarker assessment, and longitudinal follow-up for 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incident Cognitive Decline

    Incident cognitive decline will be defined as a clinically meaningful decline in cognitive performance, measured by a decrease of 1-3 points in the Mini-Mental State Examination (MMSE), or a decrease of ≥1.5 standard deviations in the composite score of the Trail Making Test (TMT), Hopkins Verbal Learning Test-Revised (HVLT-R), and Controlled Oral Word Association Test (COWA), and/or a decrease of ≥0.5 standard deviations in the Functional Assessment of Cancer Therapy-Cognitive Function Perceived Cognitive Impairment (FACT-Cog PCI) score.

    Measured: Baseline to 12 months

Secondary outcomes (6)
  1. Prevalent Cognitive Impairment

    Prevalent cognitive impairment at baseline, defined as an MMSE score <26 and/or objective cognitive impairment based on the composite score of the Trail Making Test (TMT), Hopkins Verbal Learning Test-Revised (HVLT-R), and Controlled Oral Word Association Test (COWA), and/or subjective cognitive impairment defined by a FACT-Cog Perceived Cognitive Impairment (PCI) score <54.

    Measured: Baseline

  2. Incident Delirium

    Occurrence of delirium during hospitalization, including postoperative delirium, defined as a positive 4AT screening confirmed by the Confusion Assessment Method (CAM).

    Measured: During hospitalization, up to 12 months

  3. Incident Disability

    Incident disability, defined as the development of new dependence in one or more Activities of Daily Living (ADL) or Instrumental Activities of Daily Living (IADL) during follow-up.

    Measured: Baseline to 12 months

  4. Change in Quality of Life

    Decline in quality of life, defined as a decrease of at least 10 points in the EORTC QLQ-C30 global health status score during follow-up.

    Measured: Baseline to 12 months

  5. All-Cause Mortality

    All-cause mortality occurring during the follow-up period.

    Measured: Baseline to 12 months

  6. Hospitalizations

    Occurrence of all-cause hospitalizations during the follow-up period.

    Measured: Baseline to 12 months
