NCIt related terms : Stage IVA Lip and Oral Cavity Cancer;
NCIt definition : Stage IVA includes: (T4a, N0, M0); (T4a, N1, M0); (T1, N2, M0); (T2, N2, M0); (T3,
N2, M0); (T4a, N2, M0). T4a: Lip and oral cavity cancer with moderately advanced local
disease. Lip: Tumor invades through cortical bone, inferior alveolar nerve, floor
of mouth, or skin of face, i.e., chin or nose. Oral cavity: Tumor invades adjacent
structures only (e.g., through cortical bone [mandible or maxilla] into deep [extrinsic]
muscle of tongue [genioglossus, hyoglossus, palatoglossus, and styloglossus], maxillary
sinus, skin of face). T1: Tumor 2 cm or less in greatest dimension. T2: Tumor more
than 2 cm but not more than 4 cm in greatest dimension. T3: Tumor more than 4 cm in
greatest dimension. N0: No regional lymph node metastasis. N1: Metastasis in a single
ipsilateral lymph node, 3 cm or less in greatest dimension. N2: Metastasis in a single
ipsilateral lymph node, more than 3 cm but not more than 6 cm in greatest dimension;
or in multiple ipsilateral lymph nodes, none more than 6 cm in greatest dimension;
or in bilateral or contralateral lymph nodes, none more than 6 cm in greatest dimension.
M0: No distant metastasis. (AJCC 7th ed.);
Alternative definition : NCI-GLOSS: Stage IV is divided into stages IVA, IVB, and IVC. In stage IVA, the tumor
has spread to nearby tissues in the lip and oral cavity (mouth); and/or cancer has
spread to one or more lymph nodes in the neck and the involved lymph nodes are 6 centimeters
(about 2 inches) or smaller.;
