| Guide for use: | Valid N codes from the current edition of the UICC TNM Classification of Malignant Tumours. Record the stage in Arabic numerals and the appropriate upper or lower case alphabetic character omitting the prefix "N". For example, record stage N1b for malignant melanoma of the skin as "1b". Record if the N stage value has a prefix of “c” or “p”. For example, record retinoblastoma N stage pN1 as “p1”. Refer to the TNM Supplement: A Commentary on Uniform Use, 3rd Edition for coding rules. | ||||||||

Collection and usage attributes | |||||||||
| Guide for use: | Record the absence or presence and extent of regional lymph node metastasis at the time of diagnosis of the cancer. TNM staging applies to solid tumours excluding brain tumours. Choose the lower (less advanced) N category when there is any uncertainty. The current edition of the AJCC (American Joint Committee on Cancer) Cancer Staging Manual provides an equivalent and alternative source of N stage codes. Staging classification systems other than the TNM classification system are recorded separately. | ||||||||
| Collection methods: | This information should be obtained from the patient's medical record. | ||||||||
| Comments: | Cancer stage is an important determinant of treatment and prognosis, and is used to evaluate new treatments and analyse outcomes. Survival analysis is adjusted by stage at diagnosis and distribution of cancer cases by type and stage. | ||||||||
