Abstract

Preoperative cardiopulmonary exercise testing (CPET) provides an objective measure of a patient’s functional capacity under stress. However, the association between CPET and long-term outcomes for women with ovarian cancer have not been assessed. The aim was to determine whether cardiorespiratory fitness, as measured by CPET parameters—peak oxygen uptake (VO2 peak), ventilatory efficiency at anaerobic threshold (VE/VCO2 at AT), and anaerobic threshold (AT)—could predict overall survival (OS) and recurrence -free survival (RFS) in patients with all stages of ovarian cancer. Methods: This was a retrospective cohort study of patients who underwent CPET prior to surgery for suspected or confirmed ovarian cancer during 2019–2023 at the Northern Gynaecological Oncology Centre, United Kingdom. CPET outcomes were risk-stratified, with thresholds of AT ≥ 10 mL/min, VO2 peak ≥ 15 mL/kg/min, and VE/VCO2 at AT ≤ 34 indicating lower risk. Primary outcomes included OS and RFS. Results: A total of 303 patients were included, of whom 56 (18.5%) had a staging laparotomy, 130 (42.9%) underwent primary cytoreductive surgery, and 117 (38.6%) underwent interval cytoreductive surgery. Survival analysis showed that VO2 peak ≥ 15 was significantly associated with improved OS of the whole population (p = 0.032). VE/VCO2 at AT ≤ 34 was associated with improved survival in patients with advanced stage disease (p = 0.025) after ovarian cancer surgery. There was no association between CPET parameters and RFS. Conclusions: We found that peak VO2 ≥ 15 was associated with improvement of overall survival in patients with all stages of ovarian cancer. In addition, VE/VCO2 at AT ≤ 34 was associated with overall survival in patients with advanced-stage disease.
