We recovered data form Hospital Demission Sheet, regarding the 2014-2018 period, of all patients with a primary or secondary diagnosis for breast cancer (diagnosis codes 174*, 19881 or 2330) and who underwent to the relative specific surgery (intervention codes 852*, 8533, 8534, 8535, 8536 or 854*). Overall, 8,509 Ligurian patients underwent to 9,078 surgeries in regional or extra-regional hospitals. Patients were mostly female (9 males and 8,500 females) and had a median age of 65 (IQR: 53-75; min 16; max 99). Distribution of Ligurian patients operated in Liguria per LHA of residence and years of intervention was analyzed. The higher number of surgery for breast cancer was detected in 2016 and from the following years the number ranged between 1,435-1,484. Breast Units were constituted in 2016 2 . The number of surgery per hospital characteristics in terms of Breast Units and caseload was evaluated and a progressive centralization of cases operated in Breast Units was observed; it was particularly evident in the last years (2017 and 2018).
