Abstract:
Objective:To explore the clinicopathological characteristics and factors influencing the survival of young breast cancer patients with diagnostic age below 35 years, and to provide the basis for the prevention and treatment of young breast cancer patients.Methods:Epidemiological and clinicopathological data of young female patients with newly diagnosed breast cancer from Shanxi Province Cancer Hospital between January 2015 and December 2016 were retrospectively analyzed. The data included age at diagnosis, reproductive history, history of abortion, menopausal status, and immunohistochemical results. Univariate and multivariate analysis were performed by using Cox regression model.Results:A total of 118 young breast cancer patients were collected, and the median age was 31 years old. Among them, the vast majority of 118 young breast cancer patients were invasive cancer (113 cases, accounting for 95.8%); there were 65 cases (55.1%) with tumor diameter ≤ 20 mm, 61 cases (51.7%) at N 0 stage, and 112 cases (94.9%) at M 0 stage. The positive rates of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) were 73.7% (87/118), 69.5% (82/118) and 28.8% (34/118), respectively. Luminal B breast cancer was the predominant molecular subtype, accounting for 55.1% (65/118). By the end of follow-up (median follow-up period of 60 months), the overall survival rate of young breast cancer patients was 78.8%. Multivariate analysis showed that TNM staging was an independent factor affecting overall survival in young breast cancer patients ( HR = 7.858, 95% CI 2.924-21.120, P < 0.001). Conclusions:Young breast cancer patients have unique clinicopathological features and TNM staging is an independent factor affecting the prognosis. Individualized treatment helps to improve the quality of life and prolong the survival time of patients.
