Evaluating chemotherapy-driven placental alterations and their impact on fetal development.

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: Chemotherapy during pregnancy presents a clinical challenge, balancing maternal treatment efficacy with fetal safety. While chemotherapy after the first trimester is generally considered safe, its impact on placental development remains underexplored. This study investigates the effects of commonly used chemotherapeutic agents (CAs), including anthracyclines, taxanes, and platinum-based compounds, on maternal, placental, and fetal outcomes using a mouse model. Methods: To model the chemotherapy exposure during pregnancy, pregnant mice received a single CA dose at embryonic day 13.5 (E13.5), equivalent to the beginning of the second trimester in human gestation. Placental and fetal outcomes were assessed at E15.5 and E18.5 using contrast-enhanced microtomography (micro-CT) and histopathological analyses to investigate the alterations associated to the exposure to differen CAs. Results: Platinum-based agents, particularly carboplatin, significantly reduced fetal and placental weights and altered placental morphology, with persistent effects observed at E18.5. Contrast-enhanced microtomography (micro-CT) and histopathological analyses revealed reduced placental volumes, in both the labyrinth and junctional zones, and increased signs of trophoblast degeneration. Despite these changes, embryonic viability and litter size remained unaffected, suggesting that fetal growth restriction may be driven by placental insufficiency rather than direct fetal toxicity. Conclusion: These findings underscore the importance of placental assessment in evaluating chemotherapy safety during pregnancy and highlight the potential long-term implications of platinum-based treatments on fetal development.
