• Palliative chemotherapy refers to any chemotherapy administration that is not curative but administered simply to decrease tumor load and increase life expectancy.

• Neoadjuvant: treatment given as a first step to shrink a tumor before the main treatment, which is usually surgery, is given. Examples of neoadjuvant therapy include chemotherapy, radiation therapy, and hormone therapy. It is a type of induction therapy.
• Adjuvant: additional cancer treatment given after the primary treatment to lower the risk that the cancer will come back. Adjuvant therapy may include chemotherapy, radiation therapy, hormone therapy, targeted therapy, or biological therapy.
• Concomitant Systemic Treatment/concurrent: A treatment that is given at the same time as another (es.
