A Study on Tumor Budding Guiding Individualized Surgical Planning of Early-stage Oral Squamous Cell Carcinoma.

April 24, 2026 updated by: Jinsong Hou

A Randomized，Multicenter，Prospectie，Controlled Clinical Study on Tumor Budding Guiding Individualized Surgical Planning of Early-stage Oral Squamous Cell Carcinoma.

The purpose of this study is to determine whether cervical lymph node dissection is necessarily performed in the presence of early-stage oral squamous cell carcinoma.

Detailed Description

Oral squamous cell carcinoma is the most common malignant tumor of oral and maxillofacial region, and prone to early cervical lymph node metastases. Lymphatic spread is associated with increased risk of loco-regional recurrence, therefore, the identification of lymph node metastases preoperatively is very important for the optimal surgical therapy. Recently, cervical lymph node dissection(CLND) is performed in the presence of oral squamous cell carcinoma. However, whether cervical lymph node dissection is necessarily performed in the presence of early-stage oral squamous cell carcinoma is still controversial. CLND will represent over-treatment in some case of early-stage oral squamous cell carcinoma. Therefore, How to accurately predict whether a patient should be performed CLND is important. Our previous study show that tumor budding is closely related to lymphatic spread in the oral squamous cell carcinoma. The purpose of this study is to find that whether the tumor budding guide the individualized surgical planning of early-stage oral squamous cell carcinoma.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: High-level tumor budding group with CLND
Resection for primary lesion and cervical lymph node dissection (CLND) are performed in the early-stage oral squamous cell carcinoma which tumor budding is a high level.
Procedure: Resection for primary lesion and cervical lymph node dissection
Resection for primary lesion and cervical lymph node dissection are performed in the early-stage oral squamous cell carcinoma.
Experimental: High-level tumor budding group without CLND
Only resection for primary lesion is performed in the early-stage oral squamous cell carcinoma which tumor budding is a high level.
Procedure: Resection for primary lesion only
Only resection for primary lesion is performed in the early-stage oral squamous cell carcinoma.
Experimental: Low-level tumor budding group with CLND
Resection for primary lesion and cervical lymph node dissection (CLND) are performed in the early-stage oral squamous cell carcinoma which tumor budding is a low level.
Procedure: Resection for primary lesion and cervical lymph node dissection
Resection for primary lesion and cervical lymph node dissection are performed in the early-stage oral squamous cell carcinoma.
Experimental: Low-level tumor budding group without CLND
Only resection for primary lesion is performed in the early-stage oral squamous cell carcinoma which tumor budding is a low level.
Procedure: Resection for primary lesion only
Only resection for primary lesion is performed in the early-stage oral squamous cell carcinoma.
