[Mammary carcinoma: prognosis value of intra-mammary spread (author's transl)]

At the conclusion of this study based on 327 cases of breast cancer T1, T2 T3 (less than 7 cm) No, N1, Mo Pev O, treated by mastectomy and axillary dissection without previous treatment, it appears that the microscopic dissemination to the nipple has a pejorative prognosis value. The 5 years is 84 p. 100 when there is no nipple dissemination, 74 p. 100 when there is an intraductal nipple dissemination, and 57 p. 100 when there is lymphatic or interstitial nipple dissemination. These differences have a statistical value. This value does not seem connected with other pathological prognosis factors: tumors size, Bloom histopronostic grading, and the number of nodes invaded. The intra-mammary spread without nipple involvment has no prognostical value.
