A Prospective Monocentric Study of Invasive Breast Carcinoma Diagnosed at 80 Years and Older: Survival Outcomes and Peculiar Challenges.

The lengthening of the lifespan led to an increase in breast cancer (BC) diagnosed in very old age, but the treatment recommendations in this patient group usually lack evidence-based practice. We conducted a prospective observational monocentric study specifically targeting patients diagnosed with invasive BC at 80 years of age or older. We enrolled 88 patients consecutively observed for a new BC diagnosis at 80 years or older.
