Treatment of Stage T1-2 Oral Cavity Squamous Cell Carcinoma with Clinically Node-Negative Neck (cN0)
This protocol addresses early-stage oral cavity squamous cell carcinoma (OSCC) presenting at primary tumor stage T1 or T2 with a clinically and radiographically node-negative neck (cN0) and no distant metastasis — a setting where accurate pathologic neck staging is critical to selecting appropriate further management.
Clinical scenario
Oral cavity squamous cell carcinoma at primary tumor stage T1–T2, with a clinically and radiographically node-negative neck (cN0) and no distant metastasis. These are early tumors that can be resected with appropriate margins without requiring routine elective neck dissection at the outset, making precise intraoperative neck staging the pivotal decision point.
Approach (partial — complete regimen behind the link)
Management centres on primary surgical resection of the oral cavity tumour together with an intraoperative procedure that provides pathologic staging of the neck — a finding that then determines whether additional neck treatment is required. The specific surgical technique, staging criteria, and decision algorithm for escalation are contained in the full protocol.
Full regimen, escalation criteria, and decision pathway available via the link below.

Utilization of SLN biopsy for head and neck cancer (HNC) is under active investigation with appealing applications, particularly for stage I to II (cT1-2N0M0) OSCC.
Primary T1-2 tumors that can be reliably resected with appropriate margins without requiring neck access have been deemed appropriate for SLN biopsy.
The use of SLN biopsy provides clinicians with a diagnostic procedure, which may be followed by an escalation of treatment (ie, completion neck dissection [CND]) when necessary.
