Abstract
- Abstract: Objectives: To evaluate the impact of invasion of the prevertebral or parapharyngeal spaces and large tumor volume on treatment outcomes in patients with nasopharyngeal carcinoma (NPC). Methods: A total of 105 patients with newly diagnosed NPC were enrolled in this study. TNM stage and presence of invasion of the prevertebral or parapharyngeal spaces were recorded. All patients received a total dose of 70–75Gy. Results: After controlling for age, sex, and chemotherapy status, invasion of the prevertebral or parapharyngeal spaces and large primary tumor volume produced a significantly increased hazard ratio for distant metastasis and recurrence. We defined patients with two or more such prognostic factors as high-risk patients, in whom the 3-year metastasis-free survival rate, with and without adjuvant chemotherapy, was 100% and 69.6%, respectively (P =0.02). Their 3-year recurrence-free survival rate, with and without adjuvant chemotherapy, was 93.3% and 70.2% (P =0.09). This benefit was not observed in low-risk NPC patients. Conclusion: NPC patients with any two or more of the factors, involvement of the prevertebral space, large primary tumor volume, or advanced parapharyngeal space invasion, had more recurrence and poor survival rates and benefited from concurrent chemoradiotherapy followed by adjuvant chemotherapy.
