Background: The response to chemotherapy depends on the proliferation of cancer cells. The higher the proliferation of cancer cells, the better the response. Mitotic Index and Tumor Infiltrating Lymphocytes are markers related to the rate of proliferation and cancer immunity. Objectives: to analyze the correlation of Mitotic Index (MI) and Tumor Infiltrating Lymphocytes (TILs) to chemotherapy response in Triple-negative breast cancer (TNBC). Methods: This study used an observational analytic design with a cross-sectional approach. It was conducted at the Division of Oncology Surgical, Department of Surgery, USU Medical Faculty, H. Adam Malik Hospital, Medan, for six months with a sample of 60 people. Results: On average, most respondents are 47 years old, with the youngest age being 27 and the oldest 73 years old. Most respondents have Grade II, with most in stage IIIB. There was no relationship between Tumor Infiltrating Lymphocytes and Chemotherapy Response (p\>0.05), with a Positive Predictive Value (NPP) of 47\% and a Negative Predictive Value (NPN) of 50\%. Conclusion: There is no relationship between the mitotic index and clinical response to chemotherapy, and there is no relationship between tumor-infiltrating lymphocytes and the response to chemotherapy due to influencing factors such as albumin, T stage, menopausal status, and receptor status.

Introduction: Oxidative stress due to reactive oxygen species often leads to pathogenesis of chronic diseases such as cancer. Research states that a diet rich in polyphenols renders many health benefits by scavenging such harmful reactive species. Celosia argentea (Amaranthaceae), a common weed in India has been reported as a potential source of cheap, natural antioxidants due to its phenolic abundance. In this research work efforts were made to identify and screen the phenolic rich fractions of Celosia argentea for their antioxidant and anticancer potential. Materials and Methods: Various solvent fractions with increasing polarity were subjected to total phenolic content, followed by antioxidant assays- DPPH, ABTS and anti proliferative assays- Brine shrimp Bioassay, Antimitotic and MTT assays. Results: IC50 value of methanolic fraction for DPPH assay was statistically significant (26.25; ***P\<0.001) when compared with ascorbic acid (12.50; ***P\<0.001). Also TEAC values for methanolic fraction and BHT (standard) for ABTS assay were similar (2.1; ***P\<0.001) Methanolicfraction at 400 \μg/ml exhibited strong cytotoxicity (9.0 \± 0.81; ***P\<0.001) against brine shrimps comparable to Methotrexate at 50 \μg/ml(10; ***P\<0.001) and significantly reduced mitotic index from 96.8 to 38.0 (***P\<0.001) which was further confirmed by MTT assay where IC50 value of methanolic fraction for SiHa and MCF-7 cells was found to be 28 \μg/ml with no cytotoxicity to normal cells proving its anticancer potential. Conclusion: This research proves antioxidant and anticancer potential of phenolic rich fraction of Celosia argentea and suggests it to be useful in cancer management as antifroliferative, chemo preventive and in cancer chemotherapy induced immune suppression and oxidative stress.
