* TNM—The TNM classification of malignant tumors, Tx—tumor cannot be assessed; T1–T4—size and/or extension of the primary tumor; Nx—lymph nodes cannot be assessed; N0—no regional lymph nodes metastasis; N1—regional lymph node metastasis present, at some sites, tumor spread to closest or small number of regional lymph nodes; N2—tumor spread to an extent between N1 and N3; N3—tumor spread to more distant or numerous regional lymph nodes, Mx-cancers that cannot be evaluated for distant metastasis, M0—no distant metastasis, M1,M2—metastasis to distant organs beyond regional lymph nodes.
