Abstract
Objective: To investigate quality of life (QoL) and association with surgical complexity and disease burden after surgical resection for advanced ovarian cancer in centres with variation in surgical approach. Design: Prospective multicentre observational study. Setting: Gynaecological cancer surgery centres in the UK, Kolkata, India, and Melbourne, Australia. Sample: Patients undergoing surgical resection (with low, intermediate or high surgical complexity score, SCS) for late‐stage ovarian cancer. Main Outcome Measures: Primary: change in global score on the European Organisation for Research and Treatment of Cancer (EORTC) core quality‐of‐life questionnaire (QLQ‐C30). Secondary: EORTC ovarian cancer module (OV28), progression‐free survival. Results: Patients' preoperative disease burden and SCS varied between centres, confirming differences in surgical ethos. QoL response rates were 90% up to 18 months. Mean change from the pre‐surgical baseline in the EORTC QLQ‐C30 was 3.4 (SD 1.8, n = 88) in the low, 4.0 (SD 2.1, n = 55) in the intermediate and 4.3 (SD 2.1, n = 52) in the high‐SCS group after 6 weeks (p = 0.048), and 4.3 (SD 2.1, n = 51), 5.1 (SD 2.2, n = 41) and 5.1 (SD 2.2, n = 35), respectively, after 12 months (p = 0.133). In a repeated‐measures model, there were no clinically or statistically meaningful differences in EORTC QLQ‐C30 global scores between the three SCS groups (p = 0.840), but there was a small statistically significant improvement in all groups over time (p < 0.001). The high‐SCS group experienced small to moderate decreases in physical (p = 0.004), role (p = 0.016) and emotional (p = 0.001) function at 6 weeks post‐surgery, which resolved by 6–12 months. Conclusions: The global QoL of patients undergoing low‐, intermediate‐ and high‐SCS surgery improved at 12 months after surgery and was no worse in patients undergoing extensive surgery. Compared with surgery of lower complexity, extensive surgery does not result in poorer quality of life in patients with advanced ovarian cancer. Compared with surgery of lower complexity, extensive surgery does not result in poorer quality of life in patients with advanced ovarian cancer. [ABSTRACT FROM AUTHOR]
