Nodal Ratio as a Prognostic Factor in Patients with Four or More Positive Axillary Nodes Treated with Breast-conserving Therapy and Regional Nodal Irradiation.

Aim: This study aimed to investigate the prognostic value of the axillary lymph node ratio (i.e. positive axillary nodes to nodes removed) in patients with breast cancer treated with conservative surgery and regional radiotherapy.

Breast cancer bone metastases: an epidemiologic study in selected radiation departments.

Aims: To quantify radiation treatments for bone metastases from breast cancer in three Sicilian provinces (Messina, Catania, Ragusa) with respect to the general population and the incidence and prevalence of breast cancer in this macro-area in a 8-year period.

Methods: All bone metastasis patients treated using radiotherapy in 8 radiation departments operating in the provinces of Messina, Catania and Ragusa were collected. Among these, metastases from breast carcinoma were analyzed according to year of irradiation.
