Background:
Oral potentially malignant disorder (OPMD) prognostication is limited by uncertainty of which lesions will progress and the aggressiveness of lesion progression. We defined patterns and kinetics of progression in a large cohort of OPMD subjected to serial clinical and histologic examinations.
Methods:
This 24-year study evaluated the pattern of disease progression in 668 patients with 1313 OPMDs.
Results:
The disease progression pattern was grouped as (a) non-progressive (82.5%), (b) progressive, where initial low-grade dysplasia advanced to high-grade dysplasia in subsequent lesions (5.8%), and (c) transformed, where dysplastic lesions transformed into squamous cell carcinoma (11.7%). Progression showed aggressive (< 2 years) and indolent (> 2 years) patterns. An aggressive course occurred in 48.3% of progressive and 57.6% of transformed lesions. Progression was associated with high-grade lesions, floor of mouth and palate subsites, and tobacco and alcohol use.
Conclusions:
The data from this study may be used to develop a risk-stratified approach for OPMD management.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
