Radiation Oncology/Staging

From Wikibooks, the open-content textbooks collection

Jump to: navigation, search

The purpose of this page is to provide a quick comparison of the stages that are used for various malignancies. It is not meant to go into detail of what constitutes each stage. For that information, see the article on each specific malignancy.

This page uses the lastest AJCC 6th edition from 2002.

Note: should move this information into table form

Notes: M-stage not listed unless it is different than the commonly used M0 or M1.
For simplicity, N(1-3) means N-stage can be N0 or N1-3. However, N(0-1) means N-stage is N0 or N1. These schemes are different but easier to remember.
All sites also contain T0 (no tumor) but this isn't listed below. Many sites contain Tis and Stage 0 but these aren't listed below.

The headings below are per the AJCC Cancer Staging Handbook and do not necessarily follow the Table of Contents organization of this wikibook.

[edit] Gynecologic

In all, T-stage parallels the FIGO stage, except there is no T4b (Stage IVB is M1), and in cases where the FIGO stage includes node-positive disease as a distinct stage (e.g. uterine corpus Stage IIIC). Except for vulvar, N+ makes the overall stage the highest Stage III stage. There is no T4 (and thus no IVA) for ovary and fallopian tube.
N-stage changes the FIGO stage in most, but only in vulvar cancer is there N1 vs N2.
