Heterogeneity of cytotoxic T cell infiltration in breast and colorectal cancer
نویسندگان
چکیده
Background The prognostic value of intra-tumoral cytotoxic T cells has been demonstrated in multiple tumor types. However, immune infiltrate heterogeneity can lead to potentially significant misrepresentations of marker prevalence in routine histological sections. We examined step sections of breast and colorectal cancer samples for CD8+ T cell prevalence by standard chromogenic immunohistochemistry to determine marker variability and inform practice of T cell biomarker assessment in formalin-fixed, paraffinembedded (FFPE) tissue samples.

CD8+ T cell infiltration in breast and colon cancer: A histologic and statistical analysis
The prevalence of cytotoxic tumor infiltrating lymphocytes (TILs) has demonstrated prognostic value in multiple tumor types. In particular, CD8 counts (in combination with CD3 and CD45RO) have been shown to be superior to traditional UICC staging in colon cancer patients and higher total CD8 counts have been associated with better survival in breast cancer patients. However, immune infiltrate h...

متن کاملA Bi-Functional Targeted P28-NRC Chimeric Protein with Enhanced Cytotoxic Effects on Breast Cancer Cell Lines
One of the emerging therapeutic strategies for targeted therapy of cancer is the use of chimeric proteins. The p28 peptide has the ability of selective entrance and activating apoptosis in breast cancer cells. The NRC antimicrobial peptide showed cytotoxic activity on various breast cancer including drug-resistant variants but also normal cell lines. Here we designed a chimeric protein consiste...
