Relative Dose Intensity of Trabectedin and Outcome of Advanced L-Sarcomas.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTrabectedin, which is approved for advanced soft tissue sarcoma management, has a complex mechanism of action, but can be classified as an alkylating agent. The need to maintain a high relative dose intensity (RDI) is not clearly established in this clinical setting.
methodsWe conducted a retrospective study in five expert centers to compare the progression-free survival (PFS) and overall survival (OS) of patients with advanced L-Sarcomas (liposarcomas or leiomyosarcoma) according to the RDI calculated over the first three cycles (RDI < 80% and RDI ≥ 80%). Comparisons of patients' characteristics were done using Chi-2, Fisher exact, and Wilcoxon tests. Associations between PFS/OS and RDI were estimated and tested in Cox models.
resultsOut of 332 patients treated with trabectedin between 09/1999 and 12/2021, 244 have received at least 3 cycles before progression. Among these 244 patients, the median RDI during the first 3 cycles was 83% (range, 48%-106%), the mean RDI was 81% (±14%) and 106 patients had RDI < 80%. An RDI < 80% was more frequently observed in patients treated in a center with a high volume of activity (82/169, 49%, vs. 24/75, 32%, p = 0.02), in patients who had previously received pazopanib (12/18, 67%, vs. 94/225, 42%, p = 0.04), and in patients who experienced grade 3 neutropenia during the first cycle (56/77, 73% vs. 35/127, 28%, p < 0.001). PFS did not significantly differ according to RDI (p = 0.08): HR
conclusionThis retrospective study does not support a link between high trabectedin RDI and PFS or OS for advanced L-sarcoma patients.
