Ki-67 biomarker in breast cancer of Indian women.

Background: Biological markers that reliably predict clinical or pathological response to primary systemic therapy early during a course of chemotherapy may have considerable clinical potential.

Aims: Aims of study to evaluated changes in Ki-67 (MIB-1) labeling index and apoptotic index (AI) before, during, and after neoadjuvant anthracycline chemotherapy in breast cancer in Indian women.

Materials And Methods: Breast cancer tissues were collected from Grant Medical College and Sir J.

Estrogen receptor (ER) and progesterone receptor (PgR) in breast cancer of Indian women.

Objective: To determine the expressions and relationship between estrogen receptors (ERs) and progesterone receptors (PgRs) in breast cancer in Indian women.

Participants: Surgically removed breast cancer tissues were collected from Grant Medical College and Sir JJ Group of Hospitals, Mumbai, India, taking (n = 300) cases of infiltrating duct cancer of Indian women after radical mastectomy and lumpectomy; the age- and menopausal-related subgroups satisfied this requirement.

Measurements: Statistical significance was calculated by the likelihood ratio test; relative risk served to check for significant differences.
