Change in Skeletal muscle mass
Skeletal muscle mass will be assessed assessed using CT scans. The L3 slice used for analysis will be within 3-5mm of the lower border of the L3 vertebral body across individuals. A multiple-step procedure will be used to segment images into skeletal muscle, excluding visceral adipose tissue, subcutaneous adipose tissue, organs, vessels, and bony structures.
Change in Muscle Mass assessed using D3Creatine dilution method
A capsule of D3Creatine will be given to the participant to ingest. Fasting urine sample is then collected between 2-5 days after the dose is ingested and sent for analysis. For subsequent measurements, there is some residual D3Cr remaining in muscle, so a pre- D3Creatine dose urine sample is needed to measure the D3Cr enrichment from the initial dose and a sample taken 2-5 days after the dose.
Change in Healthy Eating Index-2020 (24-hour recall)
24-Hour Dietary Recall will be assessed. Two 24-hour recalls (1 weekday and weekend day, 30-40 minutes to complete) will be captured. Interviewers record all food and beverage consumption over a 24-hour period using the USDA multi-pass method with the University of Minnesota Nutrition Data System-Research Version system. The two days at each time point will be averaged and calories (kcal), nutrients, and diet quality assessed. Diet quality will be calculated using the HEI-2020; range of 0 - 100, higher score indicating better diet quality.
Change in Healthy Eating Index-2020 (FFQ)
Recent diet will be assessed via food frequency questionnaire (FFQ). Diet quality will be calculated using the HEI-2020; range of 0 - 100, higher score indicating better diet quality.
Change in Physical activity - objective measure
Participants will receive an Actigraph GTX9 accelerometer and instructed to wear it on the waist for 7 continuous days. From the Actigraph GTX9, daily summary moderate to vigorous physical activity will be calculated.
Change in Physical activity - subjective measure
Physical Activity Recall: The interviewer administered modified physical activity questionnaire (MPAQ) will measure physical activity.
Change in Neuropathy
The Functional Assessment of Cancer Therapy (FACT)-neuropathy subscale (FACT-GOG-Ntx) will be used to assess neuropathy (38 items).
Change in Cognitive function
Cognitive function will be assessed using the Functional Assessment of Cancer Therapy (FACT)-Cog. This self-administered questionnaire includes four subscales, 'Perceived Cognitive Impairments' (20 items), 'Impact of Quality of Life' (4 items) , 'Comments from Others' (4 items), and 'Perceived Cognitive Abilities' (9 items).
Change in Arthralgia
Arthralgia: Arthralgia will be assessed via the Brief Pain Inventory.
Change in GI disturbance
The 13-item Gastrointestinal Symptom Rating Scale developed for patients with Irritable Bowel Syndrome (GSRS-IBS)with subscales on satiety, abdominal pain, diarrhea, constipation, and bloating, will be used to assess GI disturbance.
Change in lower leg lymphedema
Lower leg lymphedema will be assessed using Gynecology Oncology Cancer Lymphedema Questionnaire.
Change in BMI
Participants will be weighed in light clothing, without shoes, rounding up to the nearest 0.1 kg. Height will be measured without shoes, using a stadiometer, rounding up to the nearest 0.1 cm. BMI will be calculated from the measured weight and height.
Change in waist circumference
Waist measurement will rounded up to the nearest millimeter.
Change in Skin Carotenoids
The Veggie meter will be used to measure carotenoid levels. This method is rapid and non-invasive, and measures skin carotenoids using optical signals.
Change in Fitness
Participants will be complete a 6-minute walk test following the American Thoracic Society's standardized protocol, with the score equal to the distance walked in 6 minutes in meters.
Change in grip strength
Grip strength assessed by dynamometer. Handgrip strength is a valid, simple measure of muscle strength that correlates well with leg strength, poor mobility, and incident disability in activities of daily living.
Change in blood biomarkers
Fasting bloods will be taken. Plasma, serum and buffy coat samples will be prepared and frozen at -80 degrees C. Potential blood biomarkers include: glucose, insulin, leptin, VEGF, CRP, IL-6, TNF-α, CA-125.
Change in financial toxicity
Financial toxicity will be assessed using the Functional Assessment of Chronic Illness Therapy-COST (FACIT-COST), a measure of financial toxicity (financial distress). Values : minimum = 0 and maximum = 48. Higher scores are worse outcome.
Change in level of function and ability to perform specific tasks
Women will complete the Functional Assessment of Cancer Therapy (FACT)-ovarian cancer subscale (FACT-O) to level of function and ability to perform specific tasks.
Change in Social Support
Women will complete the MOS Social Support Survey Subscale.
Change in Social Activity
Women will complete the MOS Social Activity limitations Scale.
Change in Quality of life (SF-36)
Women will complete the Short Form Survey (SF-36) (36 items)
Change in Sleep Quality
Sleep Quality: Women will complete Pittsburgh Sleep Quality Index (PSQI).
Change in Fatigue
Fatigue: Women will complete Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-Fatigue). Values : minimum = 0 and maximum = 52. Higher scores are worse outcome.
Change in symptoms of chemotherapy assessed using the Common Terminology Criteria for Adverse Events (CTCAE)
The Common Terminology Criteria for Adverse Events (CTCAE) will be used to assess symptoms. This well-validated survey includes symptoms and adverse events related to chemotherapy. The constructs we will measure include dry mouth, mouth/throat sores, taste, appetite, nausea, vomiting, heartburn, constipation, diarrhea, abdominal pain, shortness of breath, dizziness, neuropathy, concentration, memory, pain, insomnia, anxiety, hot flashes and fatigue.
