Background
We aimed to investigate whether depth of invasion (DOI) should be an independent indication for postoperative radiotherapy (PORT) in small oral squamous cell carcinomas (SCC).
Methods
Retrospective analysis of DOI (<5, 5 to <10, ≥10 mm) and disease‐specific survival (DSS) in a multi‐institutional international cohort of 1409 patients with oral SCC ≤4 cm in size treated between...
BackgroundWe hypothesized that incorporation of tumor thickness into the tumor–node–metastasis (TNM) system will provide better prognostic information. Tumors were reclassified as T1 if ≤5‐mm thick/≤4‐cm diameter, and T2 if >5‐mm thick/≤4‐cm diameter.
MethodsA retrospective analysis was conducted of 322 patients with T1 and T2 oral squamous cell carcinoma (SCC) between 1987 and 2012. Univariable...
