Outcome Measures

Primary Outcomes

Overall 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

Secondary Outcomes

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)

Assessed by validated questionnaire and comprise the European Organisation for Research and Treatment of Cancer (EORTC), EORTC Quality of life Questionnaire Ovarian Cancer Module (QLQ)-OV28

Time frame: At baseline, 12-15 weeks after index surgery and 12 months after index surgery

Health related quality of life (HRQoL) (QLQ-ELD14)

Assessed by validated questionnaire and comprise the European Organisation for Research and Treatment of Cancer (EORTC), EORTC Quality of life Questionnaire Elderly Module (EORTC-QLQ-ELD14)

Time frame: At baseline, 12-15 weeks after index surgery and 12 months after index surgery

Health related quality of life (HRQoL) (EQ-5D-5L)

Assessed by validated questionnaire and comprise the European Organisation for Research and Treatment of Cancer (EORTC), EQ-5D-5L

Time frame: At baseline, 12-15 weeks after index surgery and 12 months after index surgery

Low anterior resection syndrome (LARS)

Assessed by the validated LARS questionnaire

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

Determining the effect of frailty on survival in advanced ovarian cancer: study protocol for a prospective multicentre national cohort study (FOLERO)

Background and purpose: There is an urgent need to improve patient-selection to surgical treatment in advanced ovarian cancer as our results showed that cytoreductive surgery was without effect or even detrimental in a yet unknown subgroup of women. With an ageing population, 30% of women with advanced ovarian cancer in Sweden are >75 years. Nevertheless, there are no recommendations on patient-selection, albeit treating an unselected population in a public and centralized health care setting. Little attention has been placed on frailty assessments in oncology, despite their potential to stratify the risk of adverse outcome and mortality. Consequently, we hypothesize that frailty is a predictor of poor survival. Patients and methods: In this Swedish multi-centre prospective cohort study, where the exposure is frailty, consecutive women with advanced ovarian cancer scheduled for surgery with curative intent are eligible for inclusion. Three different frailty instruments are evaluated preoperatively, blinded to the caregiver. The primary outcome is 2-year overall survival. With a fixed sample size of 450 patients, a two-sided α of 0.05 and β of 0.20, the study is powered to detect a difference in 2-year survival of 12.5% by frailty, assuming a 20% prevalence of frailty. The result of the study will have a direct impact on clinical management and patient-selection as the results are expected to have a high external validity. Total study-time is 5 years, with 3 years of accrual. All participating centres started accrual by September 2024. Presentation of data on primary outcome is expected 2029.
