Oral squamous cell carcinoma in the Sudan: clinical behavior, DNA ploidy and S-phase fraction characteristics.
Article in BMC oral health, 2024. 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
backgroundThe DNA ploidy and the S phase fraction (SPF) are associated with advanced tumors progression. The present study aimed to investigate the clinicopathological behavior of oral squamous cell carcinoma(OSCC) and the prognostication of the DNA ploidy and the SPF on its clinical outcomes.
methodsThis a prospective longitudinal study of 93 OSCC patients (186 specimens). Using high resolution flowcytometry, DNA analysis and SPF were performed for the primary tumor, field of cancerization and a control normal field. The patients were followed clinically for the development of recurrence or second primary tumor(SPT).
resultsAll the 93 patients are associated with wide field of cancerization. Out of the total number of cases, 28 (30%) patients developed recurrence. Of them 17 (18.3%) had regional recurrence, and eight (8.6%) had local recurrence. Second primary tumors were identified in 14 (15.1%) of the cases. Nodal metastasis, overall recurrence and SPTs were significantly associated with DNA aneuploidy and high SPF. High SPF and DNA hyperploidy showed a 28% increased risk of local recurrence (P.value = 0.032).
conclusionIn a series of 93 oral cancers who had wide field of cancerization, 30% of the patients developed recurrence, and 15% developed second primary tumors. The DNA ploidy and the SPF were independent prognosticators for the prediction of OSCC outcomes.
