Was determined by immunostaining for the Ki-67 antibody (Dako, Rates for ER/PgR were determined by immunohistochemistry (IHC), andĪ value of ≥10% was rated as positive. Immunostainingįor ER, PgR, p53, Ki-67 and HER2 was carried out as previously Proliferation (Ki-67), HER2 and p53 overexpression. The factors investigated included the presence orĪbsence of lymph node metastasis, nuclear grade, ER/PgR status, HER2 cases of 3+ had a rate of 14.6% andīreast cancer patients studied between 19. Of the biological markers, the ER- and PgR-positive rates were 74.6Īnd 61.7%, respectively. (65.9%) of the patients had pathologically negative nodes. The mean tumor diameter was 2.2 cm (range 0.1–22). The age of the patients ranged from 25 to 95 years (mean 52.2), and Table I shows the patient characteristics. The present study was approved by the ethicsĬommittee of Kumamoto City Hospital, and informed consent was Simultaneously for ER, progesterone receptor (PgR) and HER2 fromġ997, and these were analyzed as prognostic factors according to Out of these patients, 2,638 cases were evaluated

Primary breast cancer from 1987 to 2009 in Kumamoto City Hospital, The Ki-67 index was measured in 3,652 cases with Survival (OS)] according to the breast cancer subtypes, luminal, In this study, we compared the Ki-67 index withĬlinicopathological factors in 3,652 cases with early breast cancerĪs well as with prognosis [disease-free survival (DFS) and overall The proliferation biomarker Ki-67 isĬonsidered to be a prognostic factor for breast cancer and has been Used to predict the risk of recurrence and the extent ofĬhemotherapy benefits in women with node-negative, ER-positiveīreast cancer ( 4, 5). Present in all active phases of the cell cycle, except the G0 phaseĢ1 prospectively selected genes included in the Oncotype DX™ assay With 395 kDa, which is a nuclear non-histone protein that is There is great interest in its role as a proliferation marker Ki-67 is present in all proliferating cells, and One solution is to consider the Ki-67 index when Tumors, as they make up the majority of the patients with primaryīreast cancer.

Problem is how to incorporate chemotherapy into the treatment of Negative (TN) tumors that have no targets. The treatment allocation mainlyĬonsists of targeted treatments, such as endocrine therapy forĮstrogen receptor (ER)-positive tumors and anti-HER2 therapy for Therapy of early breast cancer outlines the guidelines forĮndocrine and chemotherapy treatment ( 1). Gallen International Expert Consensus on the primary Only based on the stage classification, but also on tumor biology. An attempt to understand the uniqueīiological characteristics of individual tumors to facilitate Recently, research on the biology of breast cancer It is important to take the Ki-67 index into consideration in the treatment and follow-up of breast cancer patients. A higher Ki-67 index (≥20%) significantly correlated with other biological markers, poorer prognosis and early recurrence, particularly in luminal A type tumors. Furthermore, luminal A type cases with high Ki-67 had a similar DFS as the luminal B type cases. Multivariate analysis revealed that the Ki-67 index was a significant factor for DFS, irrespective of nodal status, and that Ki-67 was a significant marker only in luminal A type tumors. Moreover, there was a significant difference in the recurrence time. Patients with a higher Ki-67 index had significantly lower disease-free survival (DFS) and overall survival rates. A higher Ki-67 index significantly correlated with a higher grade of malignancy. The Ki-67 index of HER2 tumors was 40% and that of triple negative tumors was 50%. The median Ki-67 index of tumors with luminal A was 17%, and that of luminal B type tumors was 29%. The Ki-67 index exhibited a wide range of 1-99%, with a median of 20%, and cases were divided into 2 or 3 index groups <20% and ≥20% (and ≥50%). Out of these patients, 2,638 cases were evaluated simultaneously for estrogen receptor, progesterone receptor and HER2 from 1997, and these were analyzed as a prognostic factor according to their subtypes. The Ki-67 index was measured in 3,652 cases with primary breast cancer from 1987 to 2009. The purpose of the present study was to evaluate the clinical significance of proliferative activity using the Ki-67 index as a prognostic marker and as a predictor of recurrence time in breast cancer patients. In addition to the traditional parameters, the panel recommended the use of proliferation markers and multigene assays. The choice of adjuvant systemic therapy is based on targeted therapy in line with the St.
