Undifferentiated uterine sarcoma : experience of a single center.
Article in World journal of surgical oncology, 2024. 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
objectivesTo investigate the clinicopathological characteristics and prognosis of patients with undifferentiated uterine sarcomas (UUS).
methods29 patients with UUS who were treated at our institution between 2001 and 2020 were analyzed.
resultsThe median age at diagnosis was 52 years (range: 26-70 years). The FIGO 2009 distribution by stage was as follows: stage I, 17 patients (58.6%); stage II, 5 patients (17.2%); stage III, 4 patients (13.8%); and stage IV, 3 patients (10.3%). For 28 patients who underwent surgical treatment, 27 patients (96.4%) underwent total/sub-radical/radical hysterectomy combined bilateral salpingo-oophorectomy, 17 (58.6%) pelvic lymphadenectomy, 7 (24.1%) para-aortic lymphadenectomy and 8 (28.6%) patients underwent omentectomy, as part of the initial surgical treatment. The median follow-up was 23.4 months (range: 4.5-200.2 months). 18 patients (62.1%) died during follow up, and 13 patients (72.2%, 13/18) died within 2 years after diagnosis. Median progression-free survival (mPFS) and overall survival (mOS) for the entire cohort were 15.5 and 27.4 months, respectively. 2-year and 5-year PFS were 40.3% and 26.9%. 2-year and 5-year OS were 54.0% and 36.5%. Stage-specific median PFS and OS were as follows: stage I-II-17.7 and 35.5 months, stage III-IV-6.0 and 6.7 months. Patients with recurrent UUS who underwent cytoreduction surgery associated with an improved overall survival (mOS: 52.9 vs. 17.9 months), but the difference was not statistically significant (P = 0.081).
conclusionsUUS are a rare group of tumors with an aggressive behavior and poor outcomes. A majority rapidly develops distant metastases despite surgical resection.
