Review for Disease Site

Review criteria Definitive ChemoRT or RT Post-Operative ChemoRT or RT Points
H&P Relevant history stated Duration of symptoms. Alcohol and tobacco history and current usage detailed. Duration of symptoms. Alcohol and tobacco history and current usage detailed.
Relevant physical findings Full H&N exam including indirect mirror exam or fiberoptic exam. Review of prior video stroboscopy allowed. Full H&N exam including statement regarding current state of post-operative healing.
Appropriate staging TNM stage should be based on all available data including from physical exam and CT scan. PET information if available. MRI if clinically indicated. T and N stage confirmed by pathology report.
Pathology report/Surgical reports Diagnosis of malignancy confirmed by biopsy. Histology, size of primary tumor, margin status, size, number and location of involved nodes, presence of extracapsular extension, LVSI, perineural invasion.
Appropriate patient selection for treatment/Discussion of options If appropriate was surgery first or induction chemotherapy discussed as possible treatment options? If chemotherapy given, are the indications given: positive surgical margins, extracapsular extension, other?
