3D Printed Patches Used for Revolutionary, Targeted Cancer Treatment

According to the World Health Organization, estimates for the year 2022 reveal an alarming increase in cancer cases, with 20 million new cases and 9.7 million deaths recorded, double the figures for the year 2020. Indeed, in the US, cancer is the 2nd leading cause of death, surpassed only by heart disease. However, despite constant advances in treatment research, the quest for a cure remains a major challenge. However, a study conducted by the University of South Australia offers new hope in the fight against cancer, particularly liver cancer, thanks to the use of 3D printing.

Recent research suggests that 3D-printed patches containing drugs could be a major advance in the treatment of liver cancer. Not only do they appear to kill over 80% of cancer cells, but they also reduce the risk of relapse and limit the side effects of traditional chemotherapy. This new approach could transform the way we treat this disease.

3D-Printed Patches: A Revolution in Cancer Treatment

The new 3D-printed patches, made from gels containing anti-cancer drugs (chemotherapy), are an innovative solution. They are placed precisely where the cancer has been surgically removed, targeting residual cancer cells. These patches could also reduce the side effects of conventional chemotherapy, such as nausea. Although first developed to treat liver cancer, they could also be useful against other cancers, including those of the ovaries, brain and neck. The research team prioritized the study of liver cancer because of its aggressive nature and high mortality, with relapse risks of up to 70%.
