Stage I breast cancer in a regional oncology practice in Israel 2002-2006: clinicopathologic features, risk estimation and planned therapy of 328 consecutive patients. Academic Article uri icon


  • We present the clinicopathologic features and treatment plans of 328 consecutive stage I (T1N0M0) breast cancer patients seen at a regional medical center in Israel. Predicted 10-year mortality risk was calculated using the Adjuvant! Online website. The 21-gene recurrence score (RS) (OncotypeDx™) was obtained on a minority of patients. Eighty-nine per cent of patients had estrogen receptor (ER) and/or progesterone receptor (PgR) positive tumors. In 43.3% of patients history of an invasive malignancy was reported in a first degree relative and in 15.5% specifically breast and/or ovarian cancer was reported. Chemotherapy was added to endocrine therapy in 59 ER/PgR positive patients, decreasing predicted 10-year mortality risk by a median of 1.8%. Individualized risk estimation by genetic analysis may further decrease the use of chemotherapy in stage I patients. Breast cancer screening may provide an opportunity to identify cancer prone families.
