This is because of the timelines of the two case studies: while several years ago NAC was only used for patients with specific requirements in terms of tumor diameter (e.g., greater than 3 cm), nowadays, NAC has become a standard therapy in clinical practice and is received by the majority of patients regardless of their tumor size, and especially if the tumor is categorized as Triple-Negative or HER2+ [42,43,44]. Here, ERBB2 is linked to neoplasm.
