  1. aPercentage of total number of recorded cases. bTumour sections were classified into four prognostic type groups as previously described [26]: 1, excellent prognosis type (>80% 10 year survival) includes tubulo-lobular, tubular, mucinous and invasive cribriform carcinoma; 2, good types (60% to 80% 10 year survival) includes tubular mixed, mixed ductal with special type and alveolar lobular carcinoma; 3, moderate prognosis types (50% to 60% 10 year survival) includes classical lobular, medullary, atypical medullary and lobular mixed carcinoma; 4, poor prognosis types (≤ 50% 10 year survival) includes ductal/NST, solid lobular, mixed ductal and lobular carcinoma.
