Effectiveness of the Combined WLI and Hyperthermia for GI Cancer Liver Metastasis

Effectiveness of the Combined Whole Liver Irradiation (WLI) and Hyperthermia for Unresectable Chemoresistant Multiple Liver Metastasis From Gastrointestinal Tract Cancer: Prospective Phase II Trial

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.

Study Overview

• Status: Terminated
• Conditions: Hyperthermia
• Intervention / Treatment: Radiation: Combined hyperthermia and radiation therapy

Detailed Description

1.1 gastrointestinal tract cancer liver metastasis Most mortality of the gastrointestinal tract cancer patients is related with distant metastasis, especially liver is the main site. It has been estimated that 25% of colorectal cancer patients have hepatic metastases at diagnosis, and another 50% will have their tumor recurrence in the liver within 5 years.

Selected patients who had oligo (usually 2 to 3) or isolated liver metastases resected curatively and have yielded 5-year survival rates of 50% to 60%, showing that local therapy has the potential to cure. It is only possible in less than 25% of all patients with hepatic metastasis because of medical and/or surgical reasons, furthermore two-thirds of resected patients showed ultimately liver recurrence within 2 years.

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

1.2 Radiation therapy (RT) for liver metastasis Several studies reported that whole liver RT (WLRT) can be used effectively to control severe symptoms from unresectable liver metastasis in colorectal cancer patients. However, it is well known fact that the liver is a very sensitive to RT. The radiation induced liver disease (RILD), dreadful complication without special treatment method and subset of patients could be dead, can be developed as low as 30 gray (Gy). 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.

1.3 Hyperthermia It is reported that hyperthermia is effective in S phase, Low oxygen partial pressure (pO2), low hydrogen ion concentration (pH), and low perfusion site which are known as radio-resistant. Because of these characteristics, it considered as the most valuable radiosensitizer in cancer treatment, theoretically. Furthermore, mild hyperthermia (41 to 41.5 ºC) can promote tumor reoxygenation.

1.4 Purpose of this study 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to Local Tumor Progression After Combined Hyperthermia and RT	Local progression will be defined as more than 20% size increase of metastatic lesions or new metastatic lesion in liver. Time to local tumor progression will be measured from the date of RT start to the date of local progression or last follow-up visit.	Patient will be evaluated after combined hyperthermia and RT until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 19 months.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate of Combined Hyperthermia and RT		Response will be evaluated at 3 month after combined hyperthermia and RT. Modified RECIST will be used to define resopnse.
Change in the Grade of Quality of Life at 3 Months From That Before the Combined Hyperthermia and RT	To measure the quality of life, European Organisation for Research and Treatment of Cancer (EORTC)- quality of life questionnaire (QLQ) 30 and Functional Assessment of Cancer Therapy-Hepatobiliary will be used. (grade 1 to 4, 1; not at all, 2; a little, 3; quite a bit, 4; very much)	Quality of life will be ssessed at baseline and 3 months after combined hyperthemica and RT, data reported 3 months after combined hyperthemica and RT with grade from 1 to 4.
Local Tumor Progression Free Survival Rate After Combined Hyperthermia and RT	Local progression will be defined as more than 20% size increase of metastatic lesions or new metastatic lesion in liver. Local progression free survival will be measured from the date of RT start to the date of local progression or last follow-up visit.	Response will be evaluated at 3 month after combined hyperthermia and RT. Modified RECIST will be used to define resopnse.
Adverse Event After Combined Hyperthermia and RT.	All grade III or higher toxicities (repeated measure)	Adverse event will be evaluated at 3 month. The common terminology criteria for adverse events (CTCAE) version 4.0 will be used.
Overall Survival Rate After Combined Hyperthermia and RT	Overall survival will be measured from the date of RT start to the date of death or last follow-up visit.	Pathient will be evaluated at 3 month after combined hyperthermia and RT.
