Overall survival after progression in patients with uterine carcinosarcoma: a single-center retrospective cohort study.

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
objectiveTo investigate 2-year overall survival (OS) after progression in patients with uterine carcinosarcoma (UCS).
methodsThis retrospective descriptive cohort study included patients diagnosed with progressive UCS at all stages, who underwent surgical staging with or without adjuvant therapy between January 2002 and December 2022. Clinicopathological characteristics, including recurrence patterns, were assessed using descriptive statistics, Fisher's exact test, and the chi-squared test. Prognostic factors and OS after progression were analyzed using the Cox proportional hazards model and Kaplan-Meier method, respectively.
resultsFifty-four patients (mean age, 61 years) were eligible for analysis. During primary treatment, 40 patients underwent optimal surgery, 44 received adjuvant chemotherapy with or without radiotherapy, and 43 developed progressive disease within the first 2 years (median progression-free interval: 10.5 months). Overall, 74.07% of patients developed distant or combined metastases. During salvage treatment, 22 patients received chemotherapy, 11 received a combination of chemotherapy and radiotherapy, and five underwent radiotherapy alone. The median follow-up period was 18 months, with a 2-year OS rate of 20% post-progression. Multivariate analysis revealed that leukocytosis at progression was associated with decreased survival (hazard ratio [HR], 5.98; 95% confidence interval [CI], 2.33-15.3; P<0.001). Notably, optimal primary surgery (HR, 0.31; 95% CI, 0.13-0.72; P=0.006) and chemoradiotherapy as salvage treatment (HR, 0.23; 95% CI, 0.08-0.7; P=0.009) significantly improved survival.
conclusionPatients with progressive UCS have poor OS. Optimal surgery as primary treatment combined with salvage chemoradiotherapy improves post-progression survival. Leukocytosis during disease progression significantly affects survival outcomes.
