Purpose. A practice synthesis of available evidence-based medicine data in ovarian cancer (OC), aiming to provide directions for future research. Materials and Methods. We performed a systematic review. PubMed was searched for relevant OC trials between January 2000 and December 2019. Results. Out of 865 references screened, 199 trials were found eligible for inclusion. Most trials were multicenter (83.9%). There was a trend reduction in the number of patients enrolled/per study over the years. Studies testing targeted/biological therapies dominated the second decade (60 trials in 2010-2019 versus 2 trials in 2000-2009). The proportion of trials with positive survival and clinical outcomes significantly increased from 23.8% in early 2000s to 54.1% in the last 5 years. Trials with histology/molecular biomarker criteria were more likely to meet progression-free survival endpoint than those without these selection criteria (69.2% versus 32.6%). Conclusion. This systematic review suggests a trend of increased positive studies, mainly linked to precision medicine.
