Is lymph node metastasis an advanced event of gastrointestinal stromal tumor?
Article in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveThe clinicopathological features and outcome of gastrointestinal stromal tumors (GISTs) with lymph node metastasis remain controversial owing to their low incidence. A multicenter retrospective cohort study was conducted to compare the clinicopathological features and oncologic outcomes of GIST without metastasis, with lymph node metastasis, and with distant metastasis.
designThe medical records of patients with GISTs in 16 large medical centers in China from January 2014 to December 2022 were reviewed. Patients were divided into four groups: no metastasis (988 cases, 89.1%), lymph node metastasis without distant metastasis (75 cases, 6.8%), distant metastasis without lymph node metastasis (36 cases, 3.2%), and distant metastasis with lymph node metastasis group (10 cases, 0.9%). Propensity score matching (PSM) was performed to reduce confounding factors.
resultA total of 1109 cases of primary GIST were included in this study, comprising 607 males (54.7%) and 502 females (45.3%), with a mean age of 56.6 ± 11.9 years. Compared to that in GIST without lymph node metastasis, the proportion of nongastric GIST was higher in GIST with lymph node metastasis (52.9% vs 40.7%) with a larger tumor diameter (>10 cm: 36.5% vs 18.1%) and more patients with distant metastasis (11.8% vs 3.5%). Tumor location not in the stomach, the largest tumor diameter, and distant metastasis were independent risk factors for GIST with lymph node metastasis (all P < .05). After PSM, 96, 48, 24 patients comprised no metastasis, lymph node metastasis without distant metastasis, and distant metastasis without lymph node metastasis, respectively. The relapse-free survival (RFS) of the lymph node metastasis group was comparable to that of the distant metastasis group without lymph node metastasis (P = .368) and significantly inferior to that of no metastases (P = .042). CONCLUSIONS AND RELEVANCE: The RFS of patients with GIST with lymph node metastasis was comparable to those with distant metastasis and significantly worse than those without metastasis. Lymph node metastasis is an advanced event in GIST.
