About this trial
The purpose of this study is to validate the ability of the STRATICYTE™ predictive model to predict the transformation of oral potentially malignant disorders (OPMDs) to oral squamous cell carcinoma (OSCC) in a retrospective cohort of patients who received biopsies.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
From the archive, any patient who presents with clinically evident oral lesions and biopsy-proven dysplasia (punch or scalpel biopsies; any grade or classification system)
No histological evidence of cancer with clinical follow-up data for a period of at least five years; or
OSCC development (histologic or documented evidence of invasive cancer).
Patients who had archived biopsy tissue blocks of a previous oral lesion(s) meeting the above criteria and retained at the same clinical center.
Disqualifiers
Patients with oral lesions or dysplasia with no indication of OSCC development or follow-up data of less than five years in non-OSCC patients.
Patients diagnosed with oral epithelial dysplasia concomitant with OSCC at the time of the biopsy's original pathology report or a subsequent clinical note of cancer progression within three months post-biopsy.
Trial population
The target population are patients presenting with an OPMD who have received a biopsy of their lesion. The study sample will be composed of patients with previously biopsied OPMDs from contracted clinics.

Trial outcomes
Primary outcomes
Sensitivity and Specificity
Standard measures of accuracy calculated using cross-tabulation of predicted risk category and confirmed cancer progression over a 5-year period from biopsy
Survival analysis
Kaplan-Meier analyses to compare time to a positive diagnosis of oral cancer between patients/biopsies with a STRATICYTE™ classification of Low- and Elevated-Risk.
Secondary outcomes
AUC
Area under the receiver operator curve
C-index (Harrell's)
From all possible pairs of patients, compute the number of concordant and discordant pairs. Compute C-index as the proportion of all possible pairs that are concordant.
