Chemotherapy and Other Systemic Drugs Used to Treat Gynecologic Carcinosarcomas (GCSs): A Retrospective Analysis from Hospital Clínico San Carlos (HCSC), An Academic Referral Centre for Rare Gynecological Malignancies in Madrid, Spain.
Article in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND/
objectivesGynecologic carcinosarcomas (GCSs) are rare cancers with poor prognoses. In this study, we aimed to analyze the chemotherapy regimens used to treat GCSs at our institution, as well as the patients' outcomes.
methodsWe conducted a retrospective analysis of 62 GCS patients treated at Hospital Clinico san Carlos (HCSC) from 1995 to 2024.
resultsData from 62 GCSs were analyzed. Fifty-two patients (84%) underwent surgery at diagnosis, followed by radiotherapy in 20 (38.5%) endometrial carcinosarcoma (ECS) patients and perioperative chemotherapy in 45 GCS patients (62.6%). After a median follow-up (mFollow-up) of 20 months (0-242 months), 23 GCS patients relapsed and 13 progressed after the first treatment approach, 3 of them almost immediately after surgery. The median time to disease relapse was 6 months (0-225 months) and the median time to disease progression was 0 months (0-25 months). Sixteen of the relapsing patients and fifteen of the patients who were diagnosed at stage IV received systemic treatment with carboplatin and paclitaxel, the most common forms of chemotherapy (used as first-line treatments in eight of the relapsing patients and in seven patients who were in stage IV at diagnosis). GCS patients received up to five lines. The median progression-free survival (mPFS) was 5 months for the first line, and decreased in the following lines. The median overall survival (mOS) was 24 months (13.5-34.5 months) and 11 months (1-226 months) after GCS relapse/progression.
conclusionsGCS is a rare and aggressive disease with a high recurrence rate after surgery and short progression-free survival (PFS) at advanced stages, even when a combination of oncological therapies are used. (Nevertheless, some patients achieved long disease-free survival). To the best of our knowledge, this is the first publication to provide this valuable data on this rare and aggressive disease, for which phase III and real-world data is scarce.
