Malignant salivary gland tumors of the tongue: Analysis of 29 cases.
Article in Medicina oral, patologia oral y cirugia bucal, 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
backgroundMinor salivary gland carcinomas of the tongue are rare tumors with diverse clinical and histological features and poor prognosis. Evidence regarding their characteristics and survival is limited. This study aimed to describe their clinical presentation, histology, and survival. MATERIAL AND
methodsWe conducted a retrospective study of 29 patients with a histopathological diagnosis of minor salivary gland carcinoma of the tongue, treated at a referral cancer center between January 1990 and December 2024. Clinical, histological, therapeutic, and survival data were evaluated using the Kaplan-Meier method.
resultsThe median age was 61 years (range, 21-99), with a female predominance (62.1%). The base of the tongue was the most common site (65.5%). Adenoid cystic carcinoma was the most frequent histology (48.3%), followed by adenocarcinoma (27.6%) and mucoepidermoid carcinoma (24.1%). Most patients were diagnosed at advanced stages (III-IV, 65.4%), with node involvement in 41.4% of cases. Surgery was the primary treatment modality (38%), and radiotherapy was administered in 48.3% of cases. Five-year disease-free survival was 70%, while overall survival was 35%, with a median of 87 months. Moderately differentiated tumors showed a trend toward better survival, without statistical significance.
conclusionsMinor salivary gland carcinomas of the tongue are rare and frequently diagnosed at advanced stages. Prognosis is largely influenced by histology and tumor differentiation, highlighting the importance of long-term follow-up and multicenter studies to more reliably identify prognostic factors.
