Quality of life in patients with advanced ovarian cancer after primary debulking surgery versus neoadjuvant chemotherapy: Results from the randomised SCORPION trial (NCT01461850)

Abstract Objective To investigate the effect of treatment with neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS), versus primary debulking surgery (PDS), on quality of life (QoL) in patients with advanced epithelial ovarian cancer (EOC). Design Randomised trial conducted in a single institution. Setting Division of Gynaecologic Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Sample Patients with stage‐IIIC/IV EOC and high tumour load. Methods Patients were randomised (1:1) to undergo either PDS (PDS group) or NACT followed by IDS (NACT/IDS group). Main outcome measures Quality‐of‐life (QoL) data, assessed using the European Organization for Research and Treatment of Cancer core QoL questionnaire (QLQ‐C30) and ovarian cancer module (OV28); co‐primary outcomes were the QLQ‐C30 global health score at 12 months (cross‐sectional analysis) and the difference in mean QLQ‐C30 global health score over time between treatment groups (longitudinal analysis). Results From October 2011 to May 2016, 171 patients were enrolled (PDS = 84; NACT/IDS = 87). We observed no clinical or statistically significant difference between treatment groups in any of the QoL functioning scales at 12 months, including QLQ‐C30 global health score (NACT/IDS group vs PDS group, mean difference 4.7, 95% CI −4.99 to 14.4, p = 0.340). Over time, we found lower global health scores for those undergoing PDS than for those receiving NACT (difference in mean score 6.27, 95% CI 0.440–12.11, p = 0.035), albeit this was not clinically relevant. Conclusions We found no difference in global QoL related to treatment approach at 12 months, even though patients in the NACT/IDS group reported better global health scores across the 12‐month period compared with the PDS group; these findings further confirm that NACT/IDS might be a feasible option for patients unsuitable for PDS.
