Brief summary

The study is designed as an observational cohort study, aiming to evaluate, whether a structured recording of symptoms by a mobile app contributes insight in the follow-up modalities of ovarian cancer patients.

Detailed description

The observational study will examine different follow-up modalities for ovarian cancer patients with the ultimate goal of improving follow-up strategies for an improved well-being and better clinical outcomes. The primary objective is to quantify the effects of conservative clinical diagnostics by collecting symptoms via ePRO in addition to intensive diagnostics (CA-125 testing, imaging diagnostics) during follow-up, on survival, time to clinical recurrence and well-being.
