We studied the clinical factors of metastatic risk of breast cancer in
5609 consecutive cases of unilateral invasive breast cancer, wholly t
reated and followed at Rene-Huguenin Center from 1962 to 1988, and wit
hout any other cancer (even a controlateral breast cancer). All these
patients were protocolary treated; these protocols, especially medical
treatments (chimio and hormonotherapy), being modified along with yea
rs. At 20 years, the global metastasis free survival was 56%. Clinical
size, existence of inflammatory signs, UICC clinical stage, clinical
nodal status were highly significant in the Cox multivariate analysis
(P < 0.000001). Age CP < 0.0008) and adherence to skin or underlying p
arietal (P < 0.007) were also but less significant. On the other hand,
location of the tumor, time between first signs and diagnosis were no
t predictive. The women under 35 years had more metastatic locations d
uring their evolution (P < 0.05) and maybe more visceral metastasis (N
S).
