Outcome Measures

Primary Outcomes

Disease Free Survival

Disease free survival (DFS) defined as the time interval between randomization and physical or radiographic evidence of recurrence (local/distant) or second cancer or death (all causes) whichever occur first

Time frame: From date of randomisation until the date of second cancer or death, which ever occurs earlier, assessed up to 5 years

Secondary Outcomes

EORTC QLQ-C30

Health related quality of life of the patient

Time frame: through study completion, up to 2 years

Pathological complete response (PCR)

Pathological response will be established using the grading system called chemotherapy response score (CRS). The response will be assessed based on the omentum microscopic review.

Time frame: through study completion, up to 2 years

Overall survival (OS)

Overall survival (OS) defined as time interval between randomization and death (all causes); alive patients will be censored at the last date of news

Time frame: from date of randomisation to death, assessed up to 5 years

Time for first subsequent treatment (TFST)

Time frame: up to 5 years

Post-operative mortality

Post operative mortality defined as the interval between the date of debulking surgery and the date of death due to any cause occurring within the 30 day post-surgery

Time frame: up to 5 months

Post-operative morbidity

Surgical morbidity defined as the interval between the date of debulking surgery and any events occurring within the 30 day post-surgery (All grades ≥ 3 according to the CTCAE v4.03 \& All grades ≥ 3 according to Clavien Dindo classification)

Time frame: up to 5 months

Fagotti laparoscopic score

Disease extension assessed by Fagotti score at the time of diagnosis https://www.ncbi.nlm.nih.gov/pubmed/16791447

Time frame: diagnosis

CTC-AE version 4.03 adverse events

safety assessment

Time frame: 30 days after last treatment intake, up to 1 year

questionnaire OV28

Physical, abdominal/gastrointestinal (GI), fatigue

Time frame: through study completion, up to 2 years

CHRONO: randomized trial of the CHROnology of surgery after Neoadjuvant chemotherapy for Ovarian cancer

In patients treated for advanced ovarian cancer not suitable for complete primary surgery, interval surgery after three courses of neoadjuvant chemotherapy has been considered standard management since the EORTC randomized trial published in 2010. An alternative approach with delayed surgery after six courses of neoadjuvant chemotherapy was reported in retrospective series. To assess the efficacy on progression free survival of interval cytoreduction surgery after three cycles of neoadjuvant chemotherapy compared with delayed surgery after six cycles of neoadjuvant chemotherapy. In women with ovarian cancer not suitable for primary surgical cytoreduction, surgery after six cycles of neoadjuvant chemotherapy will prove better disease-free survival than cytoreductive surgery after only three cycles. CHRONO is a multicenter, randomized phase III trial. After three courses of neoadjuvant chemotherapy, eligible patients will be randomized (1:1) to either completion surgery followed by an additional five cycles of chemotherapy (control arm) or an additional three cycles of neoadjuvant chemotherapy followed by completion surgery and then two additional cycles of chemotherapy (experimental arm). Patients in both groups will receive eight total cycles of chemotherapy. The main inclusion criteria are histologically confirmed epithelial high-grade serous or endometrioid ovarian cancer, documented FIGO stage IIIB-IVA unsuitable for complete primary surgery but considered resectable after three courses of neoadjuvant chemotherapy. The main exclusion criteria are mucinous, clear cell, carcinosarcoma, or low-grade serous histologies. The primary endpoint is progression-free survival. 210 eligible patients ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: The estimated date for completing accrual will be Q2 2023. The estimated date for presentation of the first results is Q3 2028. NCT03579394.
