Abstract:
Objective The present paper aims to analyze the clinicopathologic data of patients with operable infiltrating breast cancer and investigates the factors that influence breast cancer prognosis.
Methods The clinical data of 2342 cases with operable infiltrating breast cancer treated in the Medical Department of Breast Cancer, Tianjin Medical University Cancer Institute and Hospital, Tianjin, China from January 2002 to December 2004 were collected.The clinicopathologic characteristics of the cancer, recurrence and metastasis, and patient survival rate were retrospectively analyzed.The Nottingham prognostic index(NPI) was used to analyze their prognostic survivals.
Results The average age of patients was 51.56 years.The cases at clinical stagesⅠ, Ⅱ, andⅢaccounted for 24.38%(571), 48.8%(1143), and 26.82%(628) of patients, respectively.The cases with an NPI score of low, average, and high-risk recurrence respectively accounted for 22.25%(521), 49.15%(1151), and 28.6%(670) of patients.The estrogen receptor(ER) positive, progesterone receptor(PR) positive, and C-erbB-2 over-expression of the tumors were 54.3%(1271), 72.5%(1698), and 33.6% (787), respectively.The univariate analysis revealed that the prognostic factors affecting the 5-year disease-free survival(DFS) and overall survival(OS) included clinical staging, tumor size, lymph node status, histological grading, family history, NPI, ER, PR, and C-erbB-2 status.Moreover, age also affected the 5-year DFS.The multivariate Cox regression analysis showed that the prognostic factors that influence DFS and OS were the NPI, ER, PR, and C-erbB-2 states.
Conclusion Analysis of the clinicopathologic data of a large number of cases with operable breast cancer confirmed that NPI, ER, PR, and C-erbB-2 status were preferable indicators for breast cancer prognosis.
