The Patients With Unresectable Chemoresistant Multiple Liver Metastasis From Colorectal Cancer | Effectiveness of the Combined Whole Liver Irradiation (WLI) and Hyperthermia for Gastrointestinal Tract Cancer Liver Metastasis

The Patients With Unresectable Chemoresistant Multiple Liver Metastasis From Colorectal Cancer research study

What is the primary objective of this study?

The standard treatment of unresectable liver metastasis in gastrointestinal tract cancer is chemotherapy, but considerable portion of the patients progressed and most of the liver is converted to metastatic tumor lesions. Significant quality of life decrement was detected in those patients, especially in patients suffered severe symptoms Several studies reported that whole liver RT (WLRT) can be used effectively to control severe symptoms from unresectable liver metastasis in gastrointestinal tract cancer patients. However, it is well known fact that the liver is a very sensitive to RT. Despite symptom palliation is obtained after 20 to 30 Gy RT but only in small subset of patients get local control. In this aspect, the combined with radiosensitizer with WLRT is considered to enhance RT effect to palliate symptom and control local tumor progression, and increase the quality of life ultimately. It is reported that hyperthermia is considered as the most valuable radiosensitizer in cancer treatment, theoretically. Based on those studies, we start this prospective study to investigate the effect of combination treatment of WLRT and hyperthermia on quality of life in the patients with unresectable chemoresistant liver metastasis from gastrointestinal tract cancer.
