Clinico‑pathological profile of oral squamous cell carcinoma: a five‑year analysis of 150 cases at Alexandria University.

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
backgroundOral Squamous Cell Carcinoma exhibits variable clinicopathological behavior and prognosis across different geographic populations. Limited data are available regarding the clinicopathological characteristics and prognostic factors of this disease in Middle Eastern populations, particularly in Egypt, where late presentation and advanced disease stages remain common challenges. AIM OF STUDY: To evaluate the clinicopathological characteristics of Oral squamous cell carcinoma and assess the prognostic significance of American Joint Committee on Cancer 8th edition staging, histopathological parameters, and combined risk patterns on survival and recurrence in an Egyptian cohort.
methodsThis retrospective study included 150 Oral squamous cell carcinoma patients treated at Alexandria University between 2018 and 2022. Tumors were re-staged according to American Joint Committee on Cancer 8th edition criteria. Clinical, histopathological, and follow-up data were analyzed, including tumor differentiation, surgical margin status, perineural invasion, lymphovascular invasion, depth of invasion, and extranodal extension. Recurrence and survival outcomes were correlated with clinicopathological and combined histopathological risk factors.
resultsMean age of patients was approximately 56 years, with tongue being the commonest tumor site. Re-staging according to American Joint Committee on Cancer 8th edition resulted in significant stage migration toward advanced disease stages, particularly stage IVb. Moderately differentiated tumors represented the commonest histopathological grade. Advanced AJCC stages, depth of invasion > 10 mm, positive surgical margins, higher histological grades, positive extranodal extension, and perineural and lymphovascular positivity were significantly associated with poorer survival and higher recurrence rates. Smoking and positive family history were also significantly associated with adverse outcomes. In contrast, traditional TNM staging showed no significant association with recurrence or survival outcomes.
conclusionAmerican Joint Committee on Cancer 8th edition staging demonstrated improved risk stratification and stronger associations with recurrence and survival outcomes compared to traditional TNM staging in Oral Squamous Cell Carcinoma patients. Depth of invasion, extranodal extension, and the combined histopathological risk pattern were strongly associated with aggressive tumor behavior and poorer outcomes. These findings provide valuable data from an Egyptian and Middle Eastern population and support the integration of updated staging systems with histopathological risk assessment in Oral Squamous Cell Carcinoma management.
