Abstract:
QUAD SHOT radiotherapy (QS-RT) is a periodic, short-course, hypo-fractionated radiotherapy regimen that originated in the 1980s. It is widely used in Europe and the United States, but less so in Asia. Many clinical studies have shown that QS-RT offers significant advantages in improving quality of life and local control and has a favorable safety profile. This article systematically reviews the origin, biological mechanisms, clinical applications, efficacy, and safety of QS-RT based on existing clinical studies, discusses its clinical advantages and limitations, and considers how to optimize future treatment plans.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
