tumor size 3.4 cm, node negative, Grade 3, Stage IIA, extensive angiovascular (lymphovascular) invasion, Ki-67 = 44%, P53 = 97%, ER/PR positive. (Approximately 4-6 months prior to diagnosis I knew I had the lump.) I received 6 cycles of TAC (taxotere, adriamycin, cytoxan) and then an aggressive 4-week radiation protocol. I received Tamoxifen for 10 months, then switched to Arimidex for 7 months and am now back on Tamoxifen (2 months).
