Conditions

epithelial ovarian cancer

Brief summary

The primary outcome is Progression-Free Survival (PFS), defined as the time from randomization until the date of progression (recurrence) or death by any cause in the absence of progression.

Detailed description

Overall Survival (OS), defined for each patient as the time from randomization until the date of death from any cause., Quality-Adjusted Progression Free Survival (QAPFS), defined as the time from randomization until the date of progression (recurrence) or death by any cause in the absence of progression under consideration of the quality of life during this period., Time until First Subsequent Therapy (TFST), defined for each patient as the time from randomization until the date the patient started the next (second line) subsequent anticancer treatment. Patients not receiving a subsequent anticancer treatment at the time of analysis will be censored at the date they were last known to be alive., Quality adjusted Time Without appearance of any Symptoms and Toxicity (Q-TWiST), related to either the progression of the cancer or side effects of the trial medication from randomization until death.
