Summary

This is a prospective, observational study evaluating the effect and efficiency of different clinical treatments for patients with oropharyngeal carcinoma (OPC). The selection of treatment for individual patient is based on tumor characteristics (tumor size and tumor location), a complete assessment of therapeutic effects (treatment effectiveness, possible dysfunction after operation, function maintenance, complications, etc.), and the preferences of doctors and patients.

Detailed description

For early-stage oropharyngeal carcinoma (T1-2,N0), radiotherapy or resection of the primary tumor (transoral laser microsurgery, transoral robotic surgery, conventional transoral surgery, and open surgery) with ipsilateral or bilateral neck dissection are performed according to the guidelines of Chinese society of clinical oncology (CSCO, version 2021) and the NCCN guidelines (version 2021). Postoperative radiotherapy (RT) or chemoradiotherapy (CRT) should be considered for patients with adverse features (e.g., extranodal extension, positive margins, perineural invasion or vascular invasion). For advanced oropharyngeal carcinoma (T1-2,N1-3/T3-4,N0-3), chemoradiotherapy (CRT), resection of the primary tumor (transoral robotic surgery, conventional transoral surgery, transoral laser microsurgery, and open surgery) with ipsilateral or bilateral neck dissection or neoadjuvant therapy with appropriate therapy (surgical resection, RT or CRT) are performed according to the CSCO guidelines (version 2021) and the NCCN guidelines (version 2021). Postoperative radiotherapy (RT) or chemoradiotherapy (CRT) should be considered for patients with adverse features (e.g., pT3 or pT4 primary, pN2 or pN3 nodal disease, extranodal extension, positive margins, perineural invasion or vascular invasion). This study aims to evaluate and compare the clinical outcomes of different medical treatments in patients with same TNM stage disease, overall and stratified by HPV expression. Demographic and clinicopathological characteristics of patients enrolled were also collected to assess their associations with treatment strategies and prognoses. The rates of overall survival, disease specific survival, disease free survival, local control, regional control, and progress-free survival are analyzed in the present study.

Interventions

Type	Name	Description
PROCEDURE	Surgery for early-stage OPC	The treatment strategy for patients should be discussed by the multidisciplinary team with the goal of maximizing survival with preservation of appearance and function and planned based on the tumor extension as ascertained by clinical evaluation and careful interpretation of appropriate imaging examinations. Early-stage OPC patients (T1-2,N0) enrolled in this group will be treated with surgical resection. The surgical techniques of the primary tumor include transoral robotic surgery, conventional transoral surgery, transoral laser microsurgery (e.g., CO2 laser resection), and open surgery. Ipsilateral neck dissection should be performed for patients enrolled in this group. For patients with OPC at or approaching the midline, bilateral neck dissection should be strongly considered. Postoperative radiotherapy (RT) or system therapy/RT should be considered for patients with adverse features (e.g., extranodal extension, perineural invasion or vascular invasion).
RADIATION	RT for early-stage OPC	The treatment strategy for patients should be discussed by the multidisciplinary team with the goal of maximizing survival with preservation of appearance and function and planned based on the tumor extension as ascertained by clinical evaluation and careful interpretation of appropriate imaging examinations. Early-stage OPC patients (T1-2,N0) enrolled in this group will be treated with RT.
RADIATION	CRT for advanced OPC	The treatment strategy for patients should be discussed by the multidisciplinary team with the goal of maximizing survival with preservation of appearance and function and planned based on the tumor extension as ascertained by clinical evaluation and careful interpretation of appropriate imaging examinations. Advanced OPC patients (T1-2,N1-3/T3-4,N0-3) enrolled in this group will be treated with CRT.
OTHER	Surgery for advanced OPC	The treatment strategy for patients should be discussed by the multidisciplinary team with the goal of maximizing survival with preservation of appearance and function and planned based on the tumor extension as ascertained by clinical evaluation and careful interpretation of appropriate imaging examinations. Advanced OPC patients (T1-2,N1-3/T3-4,N0-3) enrolled in this group will be treated with surgical resection. The surgical techniques of the primary tumor include transoral robotic surgery, conventional transoral surgery, transoral laser microsurgery, and open surgery. Ipsilateral neck dissection should be performed for patients enrolled in this group. For patients with OPC at or approaching the midline, bilateral neck dissection should be strongly considered. Postoperative radiotherapy (RT) or system therapy/RT should be considered for patients with adverse features (e.g., pT3 or pT4 primary, pN2 or pN3 nodal disease, extranodal extension, or vascular invasion).
PROCEDURE	Neoadjuvant treatment for advanced OPC	The treatment strategy for patients should be discussed by the multidisciplinary team with the goal of maximizing survival with preservation of appearance and function and planned based on the tumor extension as ascertained by clinical evaluation and careful interpretation of appropriate imaging examinations. Advanced OPC patients (T1-2,N1-3/T3-4,N0-3) enrolled in this group will be treated with neoadjuvant treatment. The subsequent treatments include RT, system therapy/RT, and surgical resection with or without postoperative adjuvant therapy.
