TNM Flashcards
T1 Breast cancer
2cm or less (T1 is divided into T1a,b,c; radiation-wise it is not important)
T2 Breast cancer
more than 2cm but less than 5cm
T3 Breast cancer
more than 5cm
T4 Breast cancer
extension to chest wall; inflammatory carcinoma
cN1 Breast cancer
mobile ipsilateral Level I, II nodes
pN1 Breast cancer
micrometastasis (mi) or metastasis in 1-3 axillary LNs (a) or metastasis in IM LNs (b) pathologically but NOT clinically
The 2b and 3b in LN-Staging
the moment you have a 2b or a 3b, think about internal mammary (IM) nodes involvement
cN2a in breast cancer
pN2a in breast cancer
cN2a: ipsilateral axillary LN (I, II)
pN2a: 4-9 axillary LNs
cN2b in breast cancer
pN2b in breast cancer
cN2b: metastasis to internal mammary LNs only
pN2b: only internal mammary LNs
cN3a in breast cancer
pN3a in breast cancer
cN3a: infraclavicular LNs
pN3a: < 10 axillary LNs OR infraclavicular LNs
cN3b in breast cancer
pN3b in breast cancer
pN3c in breast cancer
cN3b: ipsilateral internal mammary and axillary LN
pN3b: Internal mammary and axillary LNs
pN3c: ipsilateral supraclavicular LNs
Low Risk breast cancer
pT1-2 pN0 (1mic)
Very low risk breast cancer
ER-pos, keine Risikofaktoren
Low/medium risk
ER-pos mit Risikofaktoren (z.B HER2-pos)
ER-negativ
Lymphnode TNM breast cancer
