 This study will builds upon a single site pilot study, evaluating short and medium term Patient reported Outcomes PRO at the Pan Birmingham gynaecological cancer centre. SOCQER-1 compared PRO Outcomes in 64 women with ovarian cancer, of whom 24 had extensive surgery; SOCQER-1 found no statistically significant difference in PRO in women undergoing standard or extensive surgery for ovarian cancer by 9 months postoperative period - however the limitations of a small sample size and a single centre study should be noted. SOCQER-2 will provide longer term PRO Outcomes and survival on a larger cohort undergoing extensive surgery and will capture variation in practice by centres. SOCQER-2 will provide good quality prospective evidence on the impact of extensive surgery on Quality of life and survival in patients with ovarian cancer in large, multiple UK gynaecological cancer centres.
