Nasopharyngeal carcinoma staging. The lower the stage the better the prognosis. Tumor confined to the nasopharynx or extenion to oropharynx andor nasal cavity without parapharyngeal involvement. This was a retrospective study of 1609 patients with nasopharyngeal carcinoma investigated by magnetic resonance imaging staged with the 7th edition of the American Joint Committee on Cancer AJCC.

See Risk Factors and Diagnosis present can be useful in staging. Carcinoma in situ. Stage IV clinical staging of patients with nasopharyngeal carcinoma.

Recently doctors have found that finding out whether there is Epstein-Barr virus EBV. Unfortunately most nasopharyngeal cancers are found at a later stage when the cancer has spread to lymph nodes or distant organs. The TNM staging system developed by the International Union against Cancer UICC and American Joint Committee on Cancer AJCC is considered the authoritative system for assessing disease progression predicting prognosis and assisting treatment selection.

Introduction Nasopharyngeal caremoma NPC is a carcmoma derived from the nasophawngeal epithelium Globally nasopharynx carcinoma is rare cancer with an annual rate of approximately 80000. The disease is particularly prevalent in East and Southeast Asia. Stage 0 zero and stages I through IV 1 through 4.

The vast majority of applicable tumors are nasopharyngeal carcinomas but other epithelial malignancies of the nasopharynx are included such as minor salivary gland tumors. An accurate staging system is crucial for cancer management. The stage is the most important prognostic factor for nasopharyngeal cancer.

Evaluations for continual suitability and improvement are needed as staging and treatment methods evolve. Early-stage NPC is difficult to diagnose clinically. Nasopharyngeal cancer staging Nasopharyngeal cancer staging refers to TNM staging of malignant tumors of the nasopharynx.

Until now most NPC patients have bben diagnosed in advanced stages. The stage provides a common way of describing the cancer so doctors can work together to plan the best treatments. Stage 4 nasopharyngeal cancer is divided into stages IVA IVB and IVC.

Stage I is a small tumor confined to nasopharynx. M0 means the cancer has not spread to other parts of the body M1 means the cancer has. Stage II is a tumor extending in the local area or that with any evidence of limited neck nodal disease.

Most patients present with Stage III or IV disease. PN is determined using a combination of laterality and location of involved lymph node and size of the metastasis The presence of extranodal extension increases the pN category pT is determined by tumor size and site of involvement. The TNM staging system anatomically classifies malignancies based on the extent of the primary tumour regional lymph node involvement and distant metastases.

Size of the tumour. The prevalence of nasopharyngeal carcinoma is characterized by an unbalanced distribution. In this article we review the evolution of the International Union Against CancerAmerican Joint Committee on Cancer staging system for nasopharyngeal carcinoma.

Stage 0 The malignant condition starts with the formation of abnormal cells found in the lining of the nasopharynx. The tumor node metastases TNM staging system for nasopharyngeal carcinoma NPC has undergone important refinement throughout the years to match the evolving technology in imaging and the changing landscape of treatment. There are just 2 M stages to describe spread of nasopharyngeal cancer.

Cancer has spread beyond the nasopharynx and may have spread to the cranial nerves the hypopharynx bottom part of the throat areas in and around the side of the skull or jawbone andor the bone around the eye. The study present a case of early-stage NPC with the symptoms of progressive ringing in the ear.
