Complete macroscopic surgical resection (CMR) requires extensive surgery and combined with chemotherapy confers best chance of survival in advanced ovarian cancer. During cytoreductive surgery 11% of women require a temporary diverting intestinal stoma. Unexpectedly, our results from a unique fully accounted for population demonstrate that survival was not improved when increasing the proportion of women in whom CMR was achieved and in a yet unidentified subgroup of women extensive surgery was detrimental. In these women surgical treatment should be omitted in favor of chemotherapy only. Accordingly, there is an imperative need to improve patient selection to surgical treatment. In Sweden, we treat an unselected population of women in a public healthcare system, where 30% of women with are \>75 years. Despite these circumstances guidelines on patient-selection are lacking. Age is an imprecise variable to base clinical decisions on but must be considered with an aging population. The dynamics between physiological changes of aging, comorbidity and medical condition are included in the concept of frailty, that has gained little attention in oncology, despite their potential to stratify risk and mortality. The FOLERO study is a prospective adequately powered national cohort study with aim to determine if frailty instruments may be used to select patient to surgical treatment. In addition, we test the feasibility of early stoma reversal after index cytoreductive surgery in a small phase I trial and follow our patients Health Related Quality of Life after state of the art surgical treatment.
Hypothesis: Frailty is a predictor of poor survival Primary objective: To assess three different frailty instruments as predictors of survival Exposure: Frailty according to the three different frailty instruments evaluated Control: No frailty according to the three different frailty instruments evaluated Primary outcome measure: Overall survival Secondary objectives (selection): * To evaluate the effect of sarcopenia on postoperative outcome and survival * To evaluate the effect of surgical extent on postoperative outcome and survival * To describe the HRQoL and symptoms of the" Low anterior resection syndrome" after surgery Phase I sub-study on the feasibility and safety of early stoma reversal (Karolinska University Hospital only) Hypothesis: Early stoma reversal in select patients with advanced ovarian cancer is feasible and safe. Primary objective: To assess the feasibility and safety of early closure of defunctioning stoma after upfront cytoreductive surgery in ovarian cancer Primary outcome measure : Feasibility and safety of early stoma reversal as measured by rate of anastomotic leakage, urgent re- operations and time-interval to adjuvant chemotherapy (defined cut-offs based on historic comparison in the study protocol)

NOT_YET_RECRUITINGOverall Survival
Overall survival time is calculated from the date of index surgery to the date of death (due to any cause), or for patients still alive to the date of last follow-up.
Time frame: 24 months after index surgery
1-year mortality
Mortality within 1-year after index surgery
Time frame: 12 months from index surgery
Health related quality of life (HRQoL) (QLQ-C30)
Assessed by validated questionnaire and comprise the European Organisation for Research and Treatment of Cancer (EORTC), Core Questionnaire (QLQ-C30)
Time frame: At baseline, 12-15 weeks after index surgery and 12 months after index surgery
Health related quality of life (HRQoL) (QLQ-OV28)

Time frame: At baseline, 12-15 weeks after index surgery and 12 months after index surgery
Postoperative complications
Assessed by validated instruments, Clavien-Dindo Classification
Time frame: 30 days after index surgery
Readmissions
Assessed by review of hospital records from the day of discharge after index surgery
Time frame: 30 days after index surgery
Length of hospital stay
Assessed by review of hospital records
Time frame: From date of index surgery to the date of discharge or at latest 90 days after index surgery
Extent of surgery vs survival
Measured by surgical complexity score (as defined by the Mayo and Karolinska Surgical Complexity scores) and Peritoneal Cancer Index (PCI) both by assessment at the preoperative multidisciplinary conference The agreement between preoperative and peroperative assessment of surgical extent needed to achive complete macroscopic resection.
Time frame: Up to 60 months after index surgery
Sarcopenia vs post-operative outcome
Sarcopenia is measured by computed tomography and different muscle groups by different software programs (e.g. Coreslicer, Slice-o-matic etc.).
Time frame: Up to 60 months after index surgery
Standard regimen of adjuvant chemotherapy
Standard regimen of adjuvant chemotherapy is defined as Carboplatin (AUC 5) and Paclitaxel (175 mg/m2) every 21 days for 6 cycles. Dose and frequency will be assessed by review of hospital records
Time frame: At 1 year after index surgery
Time interval to adjuvant chemotherapy
Assessed by review of hospital records.
Time frame: From index surgery to first infusion of adjuvant chemotherapy
Total number of hospital days and readmissions within90 days after index surgery
Total number of hospital days within 90 days after index surgery by review of hospital records
Time frame: 90 days after index surgery
Health economics
Health economics will be assessed by the Eq5D-5L validated instrument
Time frame: At baseline, 12-15 weeks after index surgery and 1 year after index surgery
Recurrence or progression free survival
Defined as the time interval between index surgery and the date of recurrence or death, whichever comes first. For event-free patients recurrence free survival is the time between index surgery and the date for the last follow-up visit by review of medical records.
Time frame: Up to 60 months after index surgery
