Treatment of Oropharyngeal Cancer Carcinoma In Situ (Tis, N0, M0)
Clinical scenario
This protocol addresses oropharyngeal cancer detected at its earliest stage: carcinoma in situ, where cancer cells are confined to the epithelium — the top layer of cells lining the oropharynx — and have not yet grown into deeper tissue layers.
Carcinoma In Situ (Tis)
No lymph node spread (N0)
No distant spread (M0)
Staging & extent
The cancer is still within the epithelium and has not yet grown into deeper layers. There is no involvement of nearby lymph nodes and no evidence of metastasis to distant sites.
Treatment approach (partial overview)
Management at this stage centres on a surgical approach targeting the superficial tissue layers. The type of surgical technique used depends on the precise extent and location of the lesion.

- It has not spread to nearby lymph nodes (N0).

- The usual treatment is surgery to remove the top layers of tissue along with a small margin (edge) of normal tissue.
- This is generally Mohs surgery, surgical stripping, or thin resection.
