Official title
METRICS Study: Metabolic Evaluation Through Resting Indirect Calorimetry in Bladder Cancer
Overview
This study is being done to learn more about energy needs and muscle function during treatment for bladder cancer. These insights can help improve future patient care. The study team found in a previous study that resting energy can be different than what estimates show. Patients with bladder cancer are known to suffer a decline in physical resilience over time. Monitoring patients to understand these changes better could help design future treatments with these vulnerabilities in mind.
Detailed description
The investigators' long-term goal is to improve cachexia treatment for patients with cancer. The project is significant because identifying cachexia earlier in its onset allows for earlier and more successful treatment. Major barriers to early detection and treatment are: 1) clear specific lab tests to confirm the diagnosis and 2) identifying when resting energy expenditure (REE) increases. It is the investigators' expectation that at the completion of these descriptive studies, key factors will be identified to guide earlier detection and treatment of cachexia. Platinum-based chemotherapy and surgery are a dual-phase treatment regimen to treat bladder cancer that has a high risk of worsening cachexia compared to other cancer types not requiring such an intensive treatment regimen. Inhibition of Growth differentiation factor 15 (GDF-15) is a promising preventive strategy against cachexia in patients with bladder cancer. Understanding GDF-15 and REE changes over the course of treatment could inform proactive rather than reactive strategies to support the health of these patients and translate to patients with other types of cancer. The objective of this application is to assess changes in GDF-15 and REE levels during the treatment course for advanced bladder cancer.
Primary outcome measures

Secondary outcome measures (8)
- Blood biomarkers [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Inflammation marker [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Immune inflammation marker [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Body composition [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Nutrition assessment [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Grip strength measurement [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Quality of Life (QOL) and Fatigue assessment [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
- Quality of Life (QOL) during bladder cancer treatment assessment [Time frame: From enrollment, prior to chemotherapy, to 3 weeks after radical cystectomy.]
