Guide for use:

A list of which lymph nodes are defined as regional lymph nodes for each cancer site may be found in the current edition of the TNM Classification of Tumours, UICC (International Union Against Cancer) or the AJCC (American Joint Committee on Cancer) Cancer Staging Manual.

The number includes all nodes examined regardless of whether they were removed and examined at a single or multiple procedures. For example, for breast cancer, record the sum of regional lymph nodes examined from node sampling, sentinel node biopsy and axillary clearance.

The number of regional lymph nodes is cumulative from all procedures that removed lymph nodes through the completion of surgeries for the initial treatment of the cancer. The initial course of treatment includes all treatments administered to the patient from diagnosis and before disease progression or recurrence.

Breast cancer:

Regional lymph nodes include all ipsilateral axillary nodes (levels 1, 2 and 3), ipsilateral internal mammary nodes, supraclavicular nodes and intramammary lymph nodes. All other nodes (including contralateral axillary, contralateral internal mammary nodes and cervical nodes) are considered to be distant metastases and should not be recorded in this data item. Definitions are from the UICC TNM Classification of Malignant Tumours, 7th Edition.

Collection methods:For cancer registries, collection of this data item should only be from notification and pathology reports relating to initial diagnosis and not for recurrent or metastatic disease.
