Ki-67 and Its Relation With Complete Pathological Response in Patients With Breast Cancer.

Introduction Ki-67 is a nuclear antigen present in the synthesis phase of the cell cycle. Studies have shown that a high value of Ki-67 results in greater response to chemotherapy with higher incidence of complete pathological response, which ultimately results in improved overall survival. Methods and materials The objective of the study was to determine the frequency of high Ki-67 levels in breast cancer patients and to find the correlation of complete pathological response in breast cancer with Ki-67 levels.

Large B cell lymphoma--year by year.

Non Hodgkin's Lymphoma (NHL) comprises a group of lymphoproliferative disorders the frequency of which continues to rise. Although many classification systems exist for identifying specific histological subtypes, NHL is generally divided into indolent (low-grade) and aggressive (intermediate- and high-grade) forms. Large B Cell Lymphoma (LBCL) is one of the commonest aggressive NHLs.
