For sternum, sacrum, coccyx, and symphysis pubis, laterality is coded 0. Note: The determination of AJCC stage group from T, N, M, and grade for bone also depends on histologic type. The Histologies Stage Table shows the selection of the AJCC Stage table based on histology. CS Tumor Size Note 1: According to AJCC tumor size is an important prognostic factor. The three dimensions of tumor size (length, width, and height) are also important to collect if documented in the patient record. Record the largest dimension of tumor size in CS Tumor Size. Record the second largest dimension of tumor size in CS Site-Specific Factor 1 and the smallest dimension of tumor size in CS Site-Specific Factor 2. Note 3: The assignment of T1and T2 categories for tumors of bone is based on tumor size. A physician's statement of the T category may be used to code CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently: for example the record may document size but not extension, other than the physician's statement of the T category. Use codes 996 and 997as appropriate to code CS Tumor Size based on a statement of T when no other size information is available. Code Description 000 No mass/tumor found 001-988 989 989 mm or larger 990 Microscopic focus or foci only and no size of focus given 991 Described as "less than 1 centimeter (cm)" 992 Described as "less than 2 cm," or "greater than 1 cm," or "between 1 cm and 2 cm" 993 Described as "less than 3 cm," or "greater than 2 cm," or "between 2 cm and 3 cm" 994 Described as "less than 4 cm," or "greater than 3 cm," or "between 3 cm and 4 cm" 995 Described as "less than 5 cm," or "greater than 4 cm," or "between 4 cm and 5 cm" 996 997 999 CS Extension Note 1: The cortex of a bone is the dense outer shell that provides strength to the bone; the spongy center of a bone is the cancellous portion. The periosteum of the bone is the fibrous membrane covering of a bone that contains the blood vessels and nerves; the periosteum is similar to the capsule on a visceral organ. Note 2: The assignment of T1and T2 categories for tumors of bone is based on tumor size. A physician's statement of the T category may be used to code CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently: for example the record may document size but not extension, other than the physician's statement of the T category. Use codes 310 and 350 as appropriate to code CS Extension based on a statement of T when no other extension information is available. Note 3: The term "skip metastasis" is not used with a consistent meaning in the literature. In some cases, it refers to discontinuous metastasis in the same bone as the primary tumor, while in other cases it refers to discontinuous metastasis in an adjacent bone, usually in the same limb. For AJCC staging, discontinuous metastasis in the same bone is classified as T3 (coded in CS Extension), and discontinuous metastasis in an adjacent bone is classified as M1b (coded in CS Mets at DX). If a primary bone tumor is stated as having "skip metastasis" or "skip lesions" with no other information regarding the bone involved, use code 820 in CS Extension.

Distant nodes are coded in CS Mets at DX. Note 2: Regional lymph nodes are defined as those in the vicinity of the primary tumor. Note 3: Regional lymph node involvement is rare. If there is no mention of lymph node involvement clinically, assume that lymph nodes are negative. Use code 999 (Unknown) only when there is no available information on the extent of the patient's disease, for example when a lab-only case is abstracted from a biopsy report and no clinical history is available.

This table shows the selection of the appropriate version of the AJCC Stage table based on histology. "Ewing" maps to the table AJCC TNM 6 and 7 Stage Ewing, which is used to derive stage group for both AJCC 6 and AJCC 7 staging. "Not Ewing" maps to the tables AJCC TNM 6 Stage Not Ewing and AJCC TNM 7 Stage Not Ewing for deriving AJCC 6and AJCC 7 stage group, respectively.
