The significant change in the Ki-67 proliferation index may suggest the reduced proliferative activity of malignant cells with neoadjuvant chemotherapy.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Purpose: The aim of this study is aimed to demonstrate the changes in the tumor diameter and expressions of vascular endothelial growth factor (VEGF), estrogen receptor (ER), progesterone receptor (PR), Ki-67, and Cerb-B2 status after neoadjuvant chemotherapy in the patients with locally advanced breast cancer.Materials and Methods: Sixty-nine patients who diagnosed with locally advanced breast cancer and treated with were prospectively evaluated.
📊
Key Findings & Data:The tumor diameter and VEGF, Ki-67, ER, PR, and Cerb-B2 expressions tested by immunohistochemistry (IHC) were evaluated before and after neoadjuvant chemotherapy.Results: There was a statistically significant reduction in the tumor diameter and in the expression of VEGF, Ki-67, ER, PR, and Cerb-B2 after neoadjuvant chemotherapy.
💡
Conclusion & Impact:The significant change in the Ki-67 proliferation index may suggest the reduced proliferative activity of malignant cells with neoadjuvant chemotherapy.

Abstract

Purpose: The aim of this study is aimed to demonstrate the changes in the tumor diameter and expressions of vascular endothelial growth factor (VEGF), estrogen receptor (ER), progesterone receptor (PR), Ki-67, and Cerb-B2 status after neoadjuvant chemotherapy in the patients with locally advanced breast cancer.Materials and Methods: Sixty-nine patients who diagnosed with locally advanced breast cancer and treated with were prospectively evaluated. The tumor diameter and VEGF, Ki-67, ER, PR, and Cerb-B2 expressions tested by immunohistochemistry (IHC) were evaluated before and after neoadjuvant chemotherapy.Results: There was a statistically significant reduction in the tumor diameter and in the expression of VEGF, Ki-67, ER, PR, and Cerb-B2 after neoadjuvant chemotherapy. Conclusion: The significant reduction in VEGF expression suggests that the tumor angiogenesis and its metastatic ability may be reduced by neoadjuvant chemotherapy. The significant change in the Ki-67 proliferation index may suggest the reduced proliferative activity of malignant cells with neoadjuvant chemotherapy.

Özet

Amaç: Bu çalışmada lokal ileri evre meme kanserli hastalarda neoadjuvan kemoterapi ile tümör çapı, tümörlü dokuda çalışılan vasküler endotelyal büyüme faktörü (VEGF), östrojen reseptörü (ER), progesteron reseptörü (PR), Ki-67 ve Cerb-B2 ekspresyonlarındaki değişimin gösterilmesi amaçlanmıştır.Gereç ve Yöntem: Çukurova Üniversitesi Tıp Fakültesi Genel Cerrahi ve Tıbbi Onkoloji Bilim Dalı’nda 2008 ve 2013 yılları arasında lokal ileri meme kanseri nedeniyle tedavi gören 69 hastanın verileri prospektif olarak araştırılmıştır. Tümör çapı, tümörlü dokuda çalışılan VEGF, Ki-67, ER, PR ve Cerb-B2 ekspresyonları immunhistokimyasal (İHK) yöntem ile neoadjuvan kemoterapi öncesi ve sonrası dönemde karşılaştırmalı olarak değerlendirilmiştir.Bulgular: Neoadjuvan kemoterapi sonrası tümör çapı, VEGF, Ki-67, ER, PR ve Cerb-B2 ekspresyonlarında istatistiksel olarak anlamlı düşüş saptandı. Sonuç: Tümör dokusunda çalışılan VEGF düzeyindeki anlamlı düşme, tümörün anjiyogenezinin ve bu yolla metastaz yapabilme yeteneğinin neoadjuvan kemoterapi etkisiyle azalabileceği sonucunu telkin etmektedir. Tümör dokusunda çalışılan Ki-67 proliferasyon indeksinde anlamlı değişim; malign hücre proliferasyonunun neoadjuvan kemoterapi etkisiyle azaldığını gösterebilir.
