**CS Lymph Nodes**

**Note 1:  ** For head and neck schemas, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemas, additional information about
lymph nodes (size of nvolved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

Head and Neck**

**Note 1:  ** Code the status of extracapsular extension whether
assessed clinically or pathologically of any involved regional lymph
node(s) coded in the CS Lymph Nodes field. Do not code the status of any
nodes coded in CS Mets at DX. Pathologic assessment takes priority over
clinical assessment.

**Note 2:  ** According to AJCC (page 24), \"Imaging studies showing
amorphous spiculated margins of involved nodes or involvement of
internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Note 1:  ** For head and neck schemas, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemas, additional information about
lymph nodes (size of involved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

node(s) coded in the CS Lymph Nodes field. Do not code the status of any

amorphous spiculated margins of involved nodes or involvement of
internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Note 1:  ** For head and neck schemas, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemas, additional information about
lymph nodes (size of involved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

**Note 1:  ** Code the status of extracapsular extension whether
assessed clinically or pathologically of any involved regional lymph
node(s) coded in the CS Lymph Nodes field. Do not code the status of any

**Note 2:  ** According to AJCC (page 24), \"Imaging studies showing
amorphous spiculated margins of involved nodes or involvement of
internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Note 1:  ** For head and neck schemas, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemas, additional information about
lymph nodes (size of involved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Note 1:  ** For head and neck schemes, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemes, additional information about
lymph nodes (size of involved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

**Note:  ** Site-Specific Factors 3-6 are used to code the presence or
absence of lymph node involvement in each of 7 different levels and
other groups defined by AJCC. The definitions of the levels are the same
for all applicable head and neck sites. One digit is used to represent
lymph nodes of a single level, with the three digits of Site-Specific
Factor 3 representing lymph nodes of, respectively, Levels I-III; the
digits of Site-Specific Factor 4 representing lymph nodes of Levels IV
and V and the retropharyngeal nodes; the digits of Site-Specific Factor
5 representing lymph nodes of Levels VI and VII and the facial nodes;
and the digits of Site-Specific Factor 6 representing the remaining
Other groups as defined by AJCC. In each digit, a code 1 means Yes, the
nodes are involved.

Head and Neck**

**Note 1:  ** Code the status of extracapsular extension whether
assessed clinically or pathologically of any involved regional lymph
node(s) coded in the CS Lymph Nodes field. Do not code the status of any
nodes coded in CS Mets at DX. Pathologic assessment takes priority over
clinical assessment.

**Note 2:  ** According to AJCC (page 24), \"Imaging studies showing
amorphous spiculated margins of involved nodes or involvement of
internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Note 1:  ** For head and neck schemas, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemas, additional information about
lymph nodes (size of involved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

Head and Neck**

**Note 1:  ** Code the status of extracapsular extension whether
assessed clinically or pathologically of any involved regional lymph
node(s) coded in the CS Lymph Nodes field. Do not code the status of any
nodes coded in CS Mets at DX. Pathologic assessment takes priority over
clinical assessment.

**Note 2:  ** According to AJCC (page 24), \"Imaging studies showing
amorphous spiculated margins of involved nodes or involvement of
internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Note 1:  ** For head and neck schemas, this field includes all lymph
nodes defined as Levels I-VII and Other by AJCC. The complete
definitions are provided in the General Instructions.

**Note 2:  ** For head and neck schemas, additional information about
lymph nodes (size of involved nodes, extracapsular extension, and levels
involved) is coded in Site-Specific Factors 1-6.

**Note 3:  ** If laterality of lymph nodes is not specified, assume
nodes are ipsilateral. Midline nodes are considered ipsilateral.

Head and Neck**

**Note 1:  ** Code the status of extracapsular extension whether
assessed clinically or pathologically of any involved regional lymph
node(s) coded in the CS Lymph Nodes field. Do not code the status of any
nodes coded in CS Mets at DX. Pathologic assessment takes priority over
clinical assessment.

**Note 2:  ** According to AJCC (page 24), \"Imaging studies showing
amorphous spiculated margins of involved nodes or involvement of
internodal fat resulting in loss of normal oval-to-round nodal shape
strongly suggest extracapsular (extranodal) tumor spread; however,
pathologic examination is necessary for documentation of the extent of
such disease.\"

**Lung**\
**CS Extension**

**Note 1:  ** Direct extension to or other involvement of structures
considered M1 in AJCC staging is coded in the data item CS Mets at DX.
This includes: sternum; skeletal muscle; skin of chest; contralateral
lung or mainstem bronchus; separate tumor nodule(s) in different lobe,
same lung, or in contralateral lung.

**Note 2:  ** Distance from Carina. Assume tumor is greater than or
equal to 2 cm from carina if lobectomy, segmental resection, or wedge
resection is done.

**Note 3:  ** Opposite Lung. If no mention is made of the opposite lung
on a chest x-ray, assume it is not involved.

**Note 4:  ** Bronchopneumonia. \"Bronchopneumonia\" is not the same
thing as \"obstructive pneumonitis\" and should not be coded as such.

**Note 5:  ** Pulmonary Artery/Vein. An involved pulmonary artery/vein
in the mediastinum is coded to 70 (involvement of major blood vessel).
However, if the involvement of the artery/vein appears to be only within
lung tissue and not in the mediastinum, it would not be coded to 70.

**Note 6:  ** Pleural Effusion.

A. Note from SEER manual: Ignore pleural effusion that is negative for
tumor. Assume that a pleural effusion is

negative if a resection is done.

B. Note from AJCC manual: Most pleural effusions associated with lung
cancers are due to tumor. However, there

are a few patients in whom multiple cytoopathologic examinations of
pleural fluid are negative for tumor.

In these cases, fluid is non-bloody and is not an exudate. When these
elements and clinical judgement dictate

that the effusion is not related to the tumor, the effusion should be
excluded as a staging element and the patient

should be staged T1, T2, or T3.

**Note 7:  ** Vocal cord paralysis (resulting from involvement of
recurrent branch of the vagus nerve), superior vena cava obstruction, or
compression of the trachea or the esophagus may be related to direct
extension of the primary tumor or to lymph node involvement. The
treatment options and prognosis associated with these manifestations of
disease extent fall within the T4-Stage IIIB category; therefore,
generally use code 70 for these manifestations. HOWEVER, if the primary
tumor is peripheral and clearly unrelated to vocal cord paralysis, vena
cava obstruction, or compression of the trachea or the esophagus, code
these manifestations as mediastinal lymph node involvement (code 20) in
CS Lymph Nodes unless there is a statement of involvement by direct
extension from the primary tumor.

**Lung**\
**CS Lymph Nodes**

**Note 1:  ** Code only regional nodes and nodes, NOS, in this field.
Distant nodes are coded in the field Mets at DX.

**Note 2:  ** If at mediastinoscopy/x-ray, the description is \"mass\",
\"adenopathy\", or \"enlargement\" of any of the lymph nodes named in
Regional Lymph Nodes, assume that at least regional lymph nodes are
involved.

**Note 3:  ** The words \"no evidence of spread\" or \"remaining
examination negative\" are sufficient information to consider regional
lymph nodes negative in the absence of any statement about nodes.

**Note 4:  ** Vocal cord paralysis (resulting from involvement of
recurrent branch of the vagus nerve), superior vena cava obstruction, or
compression of the trachea or the esophagus may be related to direct
extension of the primary tumor or to lymph node involvement. The
treatment options and prognosis associated with these manifestations of
disease extent fall within the T4-Stage IIIB category; therefore,
generally use code 70 for these manifestations. HOWEVER, if the primary
tumor is peripheral and clearly unrelated to vocal cord paralysis, vena
cava obstruction, or compression of the trachea or the esophagus, code
these manifestations as mediastinal lymph node involvement (code 20) in
CS Lymph Nodes unless there is a statement of involvement by direct
extension from the primary tumor.

**CS Lymph Nodes**

**Note 1:  ** Regional lymph nodes are defined as those in the vicinity
of the primary tumor.

**Note 2:  ** Regional lymph node involvement is rare. For this schema,
if there is no mention of lymph node involvement clinically, assume that
lymph nodes are negative (code 00). Use code 99 (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.

# Three Grade System (Nuclear Grade)

There are several sites for which a three-grade system is used. The
patterns of cell growth are measured on a scale of 1, 2, and 3 (also
referred to as low, medium, and high grade). This system measures the
proportion of cancer cells that are growing and making new cells and how
closely they resemble the cells of the host tissue. Thus, it is similar
to a four-grade system, but simply divides the spectrum into three
rather than four categories (see comparison table below). The expected
outcome is more favorable for lower grades. Soft tissue sarcomas are
evaluated using a three-grade system.

If a grade is written as 2/3 that means this is a grade 2 of a
three-grade system. Do not simply code the numerator. Use the following
table to convert the grade to SEER codes.

  -----------------------------------------------------------------------
  Term            Grade                            SEER Code
  --------------- -------------------------------- ----------------------
  1/3, 1/2        Low grade                        2

  2/3             Intermediate grade               3

  3/3, 2/2        High grade                       4
  -----------------------------------------------------------------------

# 

# Sarcoma

Sarcomas are graded low, intermediate or high grade by the pathologist.
Use the following table to convert these terms to a histologic grade.

**Note:  ** 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 1:  ** In the case of multiple simultaneous tumors, code the
tumor with greatest extension.

**Note 2:  ** Skin ulceration does not alter the Collaborative Stage
classification.

**Note 3:  ** Presence of tumor at eyelid margin takes priority over
depth of invasion in dermis/tarsal plate; i.e., code 25 takes priority
over codes 10-20.

# Three Grade System (Nuclear Grade)

There are several sites for which a three-grade system is used. The
patterns of cell growth are measured on a scale of 1, 2, and 3 (also
referred to as low, medium, and high grade). This system measures the
proportion of cancer cells that are growing and making new cells and how
closely they resemble the cells of the host tissue. Thus, it is similar
to a four-grade system, but simply divides the spectrum into three
rather than four categories (see comparison table below). The expected
outcome is more favorable for lower grades. Soft tissue sarcomas are
evaluated using a three-grade system.

If a grade is written as 2/3 that means this is a grade 2 of a
three-grade system. Do not simply code the numerator. Use the following
table to convert the grade to SEER codes.

  -----------------------------------------------------------------------
  Term            Grade                            SEER Code
  --------------- -------------------------------- ----------------------
  1/3, 1/2        Low grade                        2

  2/3             Intermediate grade               3

  3/3, 2/2        High grade                       4

# Sarcoma

Sarcomas are graded low, intermediate or high grade by the pathologist.
Use the following table to convert these terms to a histologic grade.

**Peripheral Nerves and Autonomic Nervous System; Connective,
Subcutaneous, and Other Soft Tissues**\
**CS Extension**

**Note 1:  ** Connective tissue includes adipose tissue; aponeuroses;
arteries; blood vessels; bursa; connective tissue, NOS; fascia; fatty
tissue; fibrous tissue; ligaments; lymphatic channels (not nodes);
muscle; skeletal muscle; subcutaneous tissue; synovia; tendons; tendon
sheaths; veins; and vessels, NOS. Peripheral nerves and autonomic
nervous system includes: ganglia, nerve, parasympathetic nervous system,
peripheral nerves, spinal nerves, sympathetic nervous system.

**Note 2:  ** If a vessel has a name, for example, brachial artery or
recurrent laryngeal nerve, consider it a structure (code 60).

**Note 3:  ** For tumors of the extremities and trunk ONLY, superficial
lesions are defined as those not involving the superficial muscular
fascia. Deep lesions are those that involve or are beneath the
superficial fascia.

**Note 4:  ** According to AJCC, \"All intraperitoneal visceral lesions,
retroperitoneal lesions, and intrathoracic lesions, and the majority of
head and neck tumors are considered deep.\" For coding extension of soft
tissue tumors in these sites (C47.0, C47.3-5, C49.0, C49.3-5), use only
codes 12, 32, 42, 62, 80, 95, or 99.

**Note 5:  ** Definition of Adjacent Connective Tissue: Some of the
schemes for ill-defined or non-specific sites in this manual contain a
code 40, adjacent connective tissue, which is defined here as the
unnamed tissues that immediately surround an organ or structure
containing a primary cancer. Use this code when a tumor has invaded past
the outer border (capsule, serosa, or other edge) of the primary organ
into the organ\'s surrounding supportive structures but has not invaded
into larger structures or adjacent organs. In general, these tissues do
not have specific names. These tissues form the framework of many
organs, provide support to hold organs in place, bind tissues and organs
together, and serve as storage sites for nutrients. Blood, cartilage and
bone are sometimes considered connective tissues, but in this manual
they are listed separately.

**CS Lymph Nodes**

**Note 1:  ** Regional lymph nodes are defined as those in the vicinity
of the primary tumor.

**Note 2:  ** Regional lymph node involvement is rare. For this schema,
if there is no mention of lymph node involvement clinically, assume that
lymph nodes are negative (code 00). Use code 99 (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.

**Note 1:  ** Regional lymph nodes are defined as those in the vicinity
of the primary tumor.

**Note 2:  ** Regional lymph node involvement is rare. For this schema,
if there is no mention of lymph node involvement clinically, assume that
lymph nodes are negative (code 00). Use code 99 (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.
