Change from baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-Core 30 (C30) at each postbaseline visit
Lasso di tempo: Up to approximately 5 years
The EORTC QLQ-C30 is a validated, self-administered questionnaire developed to assess the quality of life in patients with cancer. It consists of 30 questions divided into several subscales, including 5 functional scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, nausea and vomiting, and pain), a global health status/QoL scale, and a number of single-item measures that assess additional symptoms such as dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties.
Up to approximately 5 years
Change from baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) -Ovarian Cancer 28 (OV28) score at each postbaseline visit
Lasso di tempo: Up to approximately 5 years
The EORTC QLQ-OV28 is a validated, self-administered questionnaire developed as a supplementary module to the core QLQ-C30, specifically designed to assess HRQoL in participants with ovarian cancer. It contains 28 questions across several subscales, including 5 symptom scales (abdominal/gastrointestinal, peripheral neuropathy, hormonal/menopausal, chemotherapy side effects, and attitudes towards disease/treatment), 2 functional scales (body image and sexual functioning), and a number of single-item measures addressing issues such as other abdominal symptoms and hair loss.
Up to approximately 5 years
Change from baseline in EQ-5D-5L score at each postbaseline visit
Lasso di tempo: Up to approximately 5 years
The EQ-5D-5L is a validated, self-reported instrument for assessing HRQoL across 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 response levels of severity, ranging from no problems to extreme problems. The questionnaire also includes a visual analog scale for self-rated overall health on a scale from 0 (worst imaginable health) to 100 (best imaginable health).
Up to approximately 5 years
