Platinum free interval and clinical benefit of the second-line chemotherapy in recurrent uterine and ovarian carcinosarcoma: a retrospective cohort analysis.
Article in Journal of gynecologic oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveUterine and ovarian carcinosarcomas (OCSs) are rare and aggressive neoplasms. We assessed whether progression free survival after initial treatment (PFS1) was associated with the clinical benefit of chemotherapy after progression, estimated as overall survival (OS) after progression/relapse.
methodsAll consecutive patients treated with chemotherapy for stage I-IV uterine/OCS in Cochin University Hospital between 2010 and 2022 were included in this retrospective cohort. Association between PFS1 and OS after progressive disease (PD) was determined by Cox regression. Optimal PFS1 threshold for OS after PD prediction was determined by a time-dependent receiver operating characteristic-curve analysis.
resultsForty patients treated for endometrial (n=32) or OCS (n=8) were included. Median PFS1 and OS after PD were 16 months 95% confidence interval (95% CI=11-not available [NA]) and 6 months (95% CI=2-15). In patients who relapsed/progressed (n=20), OS after PD was anticipated by PFS1 (Pearson r=0.61; area under the curve=0.79; 95% CI=0.6-1). At the threshold of PFS1 ≤/>9 months (n=6/n=7), median OS post PD were 2 months (0.1-NA) and 15 months (6-NA), for patients treated with platinum/anthracycline based chemotherapy in second line. Patients receiving best supportive care alone (n=7) had a median OS post PD of 8 months (1.3-NA).
conclusionOur results highlight that a subgroup of carcinosarcomas patients exhibits a durable benefit from chemotherapy in the relapse settings, and suggest the use of PFS1, as a proxy of platinum-sensitivity, to select patients who might derive higher clinical benefit of a 2nd line of chemotherapy.
