What this trial studies

This interventional study aims to evaluate the effectiveness of heart-rate variability biofeedback intervention (HRV BI) in patients with muscle-infiltrating bladder carcinoma (MIBC) undergoing neoadjuvant chemotherapy. Participants will receive standard chemotherapy treatment and will also engage in HRV BI training sessions to learn techniques for reducing stress and improving quality of life. The study will assess various outcomes, including inflammation, quality of life, cognitive functions, and treatment results over a period of 36 months. A total of 50 subjects will be enrolled to compare the effects of HRV BI alongside standard care versus standard care alone.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years with muscle-infiltrating urothelial bladder carcinoma who have not received prior chemotherapy.

Not a fit: Patients with diabetes mellitus and symptomatic neuropathy, or those on certain medications like antiarrhythmics or opiates, may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could enhance the quality of life and treatment outcomes for bladder cancer patients undergoing chemotherapy.

How similar studies have performed: While the specific combination of HRV biofeedback and chemotherapy in bladder cancer is novel, similar approaches in other cancer types have shown promising results.
