Examination reveals a mass in the nasopharynx with cervical lymphadenopathy (2 cm, mobile, non-tender nodes at level II). Nasal endoscopy shows a friable, vascular lesion arising from the lateral nasopharyngeal wall. Biopsy confirms squamous cell carcinoma. CT staging shows the primary tumour confined to the nasopharynx with ipsilateral cervical node involvement but no distant metastases. Which TNM stage is this patient classified as?
