Abstract:
Objective To analyze the association between clinicopathological features and molecular subtypes of breast carcinoma in women aged under 35 years old. Methods The clinicopathological data of 385 women aged under 35 years old who had complete data and were diagnosed as breast cancer from July 2009 to May 2016 were retrospectively analyzed. The relationship between clinicopathological features and molecular subtypes was analyzed by using nonparametric Kruskal-Wallis H test. Results In 415 cases, 385 cases were invasive ductal carcinoma, 22 cases were ductal carcinoma in situ, 4 cases were mucinous adenocarcinoma, 3 cases were invasive lobular carcinoma, 1 case was lobular carcinoma in situ. In invasive ductal carcinoma, luminal B type was the most [218 cases (56.6%)], and 60 cases (15.6%) were triple negative breast cancer (TNBC). There were significant differences in tumor mass, N stage, histological grade and clinical stage between the different molecular subtypes (all P < 0.05). Conclusions Tumor size, histological grade, lymph node staging and clinical stage of young female patients with breast carcinoma are closely associated with different molecular subtypes. The ratio of molecular subtypes with poor prognosis, higher histological grade and later clinical stage is high in all cases, which is related to the poor prognosis of young women breast carcinoma and should be paid more attention to the early diagnosis.
