Comment on 'An increase in tumor-infiltrating lymphocytes after treatment is significantly associated with a poor response to neoadjuvant endocrine therapy for estrogen receptor-positive/HER2-negative breast cancers' by Fukui et al

Abstract

This is a comment on the article by Fukui et al. investigating the relationship between tumor-infiltrating lymphocytes (TILs) and response to neoadjuvant endocrine therapy in estrogen receptor-positive/HER2-negative breast cancer. While their data are quite interesting, some information crucial for interpreting the results of this study is missing. Therefore, I would like the authors to provide additional data.
