Neoadjuvant immunochemotherapy to shrink advanced oral and oropharyngeal cancers before surgery

Official title: A Bidirectional Observational Clinical Study of Tumor Regression Patterns in Patients With Locally Advanced Oral and Oropharyngeal Squamous Cell Carcinoma Treated With Neoadjuvant Immunochemotherapy

Run by Zhujiang Hospital · NCT07133958 · Data updated 2026-11-12

This project tests two cycles of neoadjuvant immunochemotherapy (tislelizumab with paclitaxel plus cisplatin or carboplatin) in people with locally advanced oral or oropharyngeal squamous cell carcinoma to see tumor response and survival outcomes.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–80 with locally advanced (T3–4) oral or oropharyngeal squamous cell carcinoma without distant metastasis who have adequate blood, liver, renal and overall organ function and can tolerate chemoimmunotherapy and surgery.

Probably not a fit

Patients with distant metastases, poor organ function, pregnancy or lactation, or those unable to tolerate combination chemoimmunotherapy or planned surgery are unlikely to benefit.

What this trial studies

This bidirectional, single-center case series at Zhujiang Hospital enrolled 35 patients from April 2023 onward with locally advanced (T3–4) oral or oropharyngeal squamous cell carcinoma who received two cycles of neoadjuvant immunochemotherapy (tislelizumab + paclitaxel + cisplatin/carboplatin). Data were collected retrospectively and prospectively to describe treatment safety, tumor regression patterns, and short- and longer-term outcomes including 2-year progression-free survival and 5-year overall survival. Eligible patients were adults age 18–80 without distant metastases and with adequate blood, liver, kidney and organ function who could tolerate surgery. The study is single-arm and observational, documenting real-world responses rather than comparing treatment arms.

Why it matters

Potential benefit: If successful, this approach could reduce tumor size before surgery, potentially improving resectability and longer-term survival.

How similar studies have gone: Other neoadjuvant immunotherapy or chemo‑immunotherapy studies in head and neck cancers have reported promising tumor shrinkage and pathologic responses, though definitive long-term survival benefits remain under investigation.
