Treatment of Oropharyngeal Cancer Carcinoma In Situ (Tis, N0, M0)
This protocol addresses oropharyngeal cancer at its earliest recognised stage: carcinoma in situ confined to the epithelium, with no spread to lymph nodes or distant sites.
Clinical Scenario
- Cancer is confined to the epithelium — the top layer of cells lining the oropharynx — and has not yet grown into deeper layers (Tis, carcinoma in situ).
- No spread to nearby lymph nodes (N0).
- No spread to distant parts of the body (M0).
Treatment Approach
The management of oropharyngeal carcinoma in situ at this stage may involve radiation therapy — particularly when prior surgical intervention has not achieved lasting control. The full structured regimen specifies the complete pathway.
Full protocol details, sequencing, and decision criteria available via the link below.
References
The cancer is still within the epithelium (the top layer of cells lining the oral cavity and oropharynx) and has not yet grown into deeper layers (Tis, carcinoma in situ).
It has not spread to nearby lymph nodes (N0).
It has not spread to distant parts of the body (M0).
Carcinoma in situ that keeps coming back after surgery may need to be treated with radiation therapy.
