Impact of adjuvant therapy on oncologic outcomes in uterine-confined clear cell carcinoma of the endometrium.
Article in Gynecologic oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 determine the impact of adjuvant therapy on oncologic outcomes in patients with 2009 International Federation of Gynecology and Obstetrics (FIGO) stage IA, IB, or II endometrial clear cell carcinoma (ECCC).
methodsWe conducted a retrospective review at 4 international institutions. Patients with newly diagnosed clinical stage I or II disease of either clear cell or mixed histology with a clear cell component treated between 01/01/2000-12/31/2015 were included. Oncologic outcomes were assessed for patients based on adjuvant treatment received, including chemotherapy, radiation, or chemotherapy with radiation.
resultsOf 125 patients identified and analyzed, 77 (61.6%) had clear cell histology and 118 (94.4%) had stage I disease. Median age at diagnosis was 65 years (range, 33-91). All patients underwent hysterectomy, bilateral salpingo-oophorectomy, and lymph node assessment. Twenty-five patients (20.0%) underwent surgical management alone and 100 (80.0%) received adjuvant therapy: 20 (16.0%) received postoperative chemotherapy, 47 (37.6%) received postoperative radiation, and 33 (26.4%) received postoperative chemotherapy with radiation. Median follow-up was 88.4 months (range, <1-234). Progression-free survival (PFS) or overall survival (OS) did not significantly differ between surgery alone and type of adjuvant therapy (P = 0.18 and P = 0.56, respectively). Patients with mixed ECCC did not have a survival advantage over those with pure ECCC (5-year PFS rate, 85.0% vs 82.7%, P = 0.77; 5-year OS rate, 88.3% vs 91.2%, P = 0.94).
conclusionsReceipt of adjuvant therapy in surgically staged I/II ECCC did not appear to offer a survival advantage over observation alone. Adjuvant therapy in early-stage ECCC with consideration of molecular classification should be evaluated.
