2.1. CR CR remains a critical and versatile tool in cancer

CR plays a crucial role in cancer treatment and is a treatment, serving as either a primary treatment or
cornerstone of the multidisciplinary approach to managing adjuvant therapy. Its significance is underscored by its
various types of cancers. This therapeutic modality utilizes ability to control or eliminate tumors, contribute to a
