Staging classifications are a coded format, usually
numerical, that generally have increasing values that
represent which of the following?
More aggressive cancer
More extensive cancer
,A higher grade of tumor
A higher morphology code - CORRECT ANSWERS ✔✔More
extensive cancer
Staging classifications are a coded format, usually
numerical, that have increasing values that represent
greater extent of disease, or disease involvement. A
higher stage cancer is not necessarily the most
aggressive as some cancers are by nature more
aggressive than others. Tumor grade is different than
staging and is used to describe how much or how little
the cancer cells resembles the normal tissue from which
it arose. The morphology code denotes the type of cancer
and does not represent stage.
According to the general rules in the AJCC Cancer Staging
Manual, direct extension of the primary tumor into
regional lymph nodes is considered:
Local disease
Regional lymph node metastasis
Direct extension into the surrounding tissues
Distant disease - CORRECT ANSWERS ✔✔Regional lymph
node metastasis
Direct extension of the primary tumor into regional lymph
nodes is considered lymph node metastasis and is
, classified in the AJCC N category for regional nodal
involvement.
