Ex vivo 3D micro-tumour testing platform for predicting clinical response to platinum-based therapy in patients with high-grade serous ovarian cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Around 20% of patients with primary high-grade ovarian cancer do not respond to chemotherapy, but predictive biomarkers are lacking. The purpose of the current study is to establish and clinically validate an ex vivo 3D micro-tumour testing platform that predicts patient-specific response to standard of care chemotherapy. 104 ovarian cancer patients with malignant ascites were included in the study. Micro-tumours enriched from ascites were exposed to standard of care chemo- and targeted therapies, imaged using a high-content 3D screening platform. Morphological features were extracted for sensitivity profiling. A linear regression model was trained to predict the patient's CA125 decay rates, which were correlated to clinical outcomes (patient CA125 decay rate, change in tumour size, and progression-free survival). Isolated micro-tumours recapitulated ovarian cancer markers. A significant correlation (R = 0.77) between predicted and clinical CA125 rates was observed. Patients with predicted high ex vivo sensitivity to carboplatin/paclitaxel demonstrated significantly increased PFS and decreased tumour size. Complementary, patient-specific response profiles for second-line therapies were calculated and presented in integrated reports. In conclusion, an ex vivo 3D micro-tumour testing platform was established that predicted clinical response to neo-adjuvant chemotherapy in ovarian cancer patients and measured patient-specific responses to second-line therapies as a proof-of-concept. The platform enabled stratification of responders vs non-responders and has the potential to support informed treatment decisions after prospective validation. Results are generated within 2 weeks after sample collection, aligning with the clinical time frame for treatment decision-making.
