What this trial studies

This clinical trial investigates the impact of inhalation anesthesia versus total intravenous anesthesia on the immune system and mortality rates in patients undergoing surgery for breast cancer. It aims to determine whether the choice of anesthesia influences immune responses and long-term survival outcomes. The study will recruit 130 patients aged 45 to 74 with operable breast cancer, assessing their neutrophil-lymphocyte ratio as a key indicator of immune status. Participants will be randomly assigned to receive either sevoflurane or propofol anesthesia, with outcomes evaluated post-surgery.

Who should consider this trial

Good fit: Ideal candidates are women aged 45 to 74 with primary operable breast cancer at IA-IIA stages without prior chemotherapy.

Not a fit: Patients with recent cardiovascular events, chronic kidney disease, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into optimizing anesthesia choices to improve immune function and survival rates in breast cancer patients.

How similar studies have performed: Previous studies have suggested potential differences in outcomes based on anesthesia type, indicating that this approach may yield valuable insights.
