PFS defined as time from randomisation until the date of first progression or death, whichever occurs first. PFS will be assessed using computed tomography (CT) or magnetic resonance imaging (MRI) and according to Response Evaluation Criteria in Solid Tumours (RECIST) v1.1.

Detailed description

OS defined as time from date of randomisation until the date of death from any cause., PPFS defined as the date from randomisation until the date of first progression in the peritoneum or death for any cause, whichever occurs first. PPFS will be assessed using CT/MRI and according to RECIST v1.1., TFST defined as the time from the date of randomisation until the date of first subsequent anticancer therapy or death from any cause, whichever occurs first. Planned post-operative chemotherapy and planned maintenance therapy is considered as a part of the primary treatment and should not be assessed as new subsequent anticancer therapy., TSST defined as the time from the date of randomisation to the date of second subsequent anticancer therapy or death from any cause, whichever occurs first.
