Independent factors associated with advanced testicular germ cell tumors: the roles of smoking, lymphovascular invasion, and tumor size.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTesticular germ cell tumors (TGCTs) are the most common solid malignancies among young men. Although overall survival exceeds 95%, a subset of patients still present with advanced disease or relapse. Identifying clinicopathological and modifiable lifestyle factors associated with advanced-stage presentation may improve risk stratification and guide management.
methodsThis retrospective study included 96 patients with TGCTs treated at a single tertiary center. Data on smoking status, body mass index (BMI), lymphovascular invasion (LVI), and tumor size were analyzed. Associations between these parameters and stage at diagnosis were assessed using chi-square tests and multivariable logistic regression. Recurrence-free survival (RFS) was evaluated by the Kaplan-Meier method.
resultsAmong 96 patients (median age, 31 years), 59.4% had early-stage and 40.6% had advanced-stage disease. Smoking (OR = 8.17; p = 0.014), LVI (OR = 70.23; p < 0.001), and tumor size ≥ 4 cm (OR = 12.00; p = 0.009) were independently associated with advanced-stage presentation, whereas BMI showed no significant association. Recurrence occurred in 13.5% of patients, more frequently among smokers and LVI-positive cases, though not statistically significant.
conclusionSmoking, lymphovascular invasion, and tumor size ≥ 4 cm were independently associated with advanced-stage presentation in TGCTs, whereas obesity showed no significant association. The combined evaluation of pathological and lifestyle factors may enhance individualized risk stratification and inform future risk-adapted management strategies.
