Summary
Oral carcinoma in situ (CIS) presents with varied clinical appearances and affects high-risk sites like the tongue and floor of mouth. Further research is essential to understand its progression and potential regression.
Area of Science:
- Oral pathology
- Oncology
- Dermatology
Background:
- Oral carcinoma in situ (CIS) is a significant precursor to invasive oral cancer.
- Understanding the clinical and histological characteristics of oral CIS is crucial for early detection and management.
Purpose of the Study:
- To investigate the clinical and histological parameters of oral carcinoma in situ (CIS).
- To identify high-risk sites and clinical presentations of oral CIS.
- To highlight knowledge gaps regarding oral CIS progression and regression.
Main Methods:
- Retrospective analysis of seventy-seven patients diagnosed with oral CIS.
- Clinical data collection on lesion appearance (white, red, combined).
- Histological examination of tissue samples to assess cytologic alterations.
Main Results:
- Oral CIS occurred in 49 males and 28 females.
- White lesions constituted 45.1%, red lesions 15.9%, and combined 8.5%.
- High-risk sites included floor of mouth (23.2%), tongue (22.0%), and lips (19.5% in males).
- Histological variations observed in keratinization, epithelial thickness, and cell orientation (most consistent change).
Conclusions:
- Oral CIS exhibits diverse clinical and histological features.
- Specific anatomical locations are identified as high-risk sites for oral CIS development.
- Significant gaps exist in understanding oral CIS regression and its transition to invasive carcinoma, necessitating further research.
