Q: Case Study 1
A 55-year-old man with Stage III squamous cell carcinoma of the left retromolar area and left lateral tongue, with metastasis to the left neck, presents for a cleaning appointment prior to his continuing radiation therapy. The radiation field includes the entire neck, mandible, TMJ, and posterior of the maxilla. The examination reveals multiple teeth with cervical caries. The patient has a well-fitting maxillary partial denture, replacing teeth #1 to 5 and #12 to 15. Periodontal involvement includes pocketing ranging from 5 to 7 mm on the maxillary anterior teeth and generalized on the mandibular arch. The plaque level is moderate, with heavy calculus and stain. The patient drinks occasionally and smokes two packages of cigarettes daily. He brushes his teeth twice daily and rinses with Listerine once each day.

Reference: Ref 55-1

Open and read the attached case to answer the following question. Cancer staging is based on the following:

- rate of growth of tumor and if metastasis has occurred
- tumor size, lymph node involvement, and if metastasis has occurred
- tumor type, tumor size, and rate of growth of tumor
A: tumor size, lymph node involvement, and if metastasis has occurred
