Brief Summary The main goals of deep hyperthermia combined with external beam radiation (EBRT) on bone metastases are the response on pain relief, duration of response and time to achieve complete pain relief.
Detailed Description

The goal of this study is to conduct comparative data on the efficacy of low temperature (40-43℃ range) deep hyperthermia adding on external beam radiation for treatment of metastatic bone tumors. There are 3 reasons of conducting this clinical trial. Firstly, radiotherapy is most effective modality for bony metastases treatment, but only limited radiation dose can be delivered to metastatic bony metastatic sites with relatively short response duration observed clinically. Since it is a palliative treatment for pain relief, some patients develop recurrent pain at the same lesions a few months later. Most patients must accept their hopeless conditions and accept toward the end of their lives due to difficulty of reirradiation. There is urgently need for more effective treatment. Secondly, most combination of hyperthermia and radiation trials were relatively high dose of radiation, with the basic idea of hyperthermic radiosensitization, the combination of hyperthermia and radiotherapy on bone metastasis is warrant. Clinical trials experiences on relatively less deep tumors such as breast, head and neck cancers, extremity sarcoma or melanoma may not be applied on deep seated tumors. Bony metastases are usually deep seated lesions with hard cortex bone surrounded. The real benefit of hyperthermia can be highlighted on bony metastases. Thirdly, metastatic bony microenvironment are critical for the providing of bone marrow-derived immune suppressor cells circulating to systemic tumor microenvironment, mild thermal therapy to metastatic bony microenvironment may have dual immunomodulatory effects: direct enhancement of immune cell activity through thermally sensitive molecular pathways associated with immune cell function/activation, and, indirect enhancement of immunosurveillance through a reduction in hypoxia-induced immune suppressor cells around metastatic foci via improved tumor vascular perfusion. An unexpected survival benefit may demonstrated from this study.

Patients are stratified according to solitary or multiple sites, primary cancer type (Breast or prostate vs others), and severity of pain (i.e., worst pain score in the last 24-hour period) (4-6 vs 7-10). Patients are randomized to 1 of 2 treatment arms.

Treatment protocol A was designed to compare the response of matched tumors in the same patient treated by radiation alone or by radiation combined with hyperthermia when the patient had multiple tumors. Two tumors of comparable size were treated with either protocol A or B, and the responses were compared. The tumor size was computed as the product of maximum length times maximum width.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Histologically or clinically confirmed solid tumor metastasis with index lesion involving or abutting bone. *Index lesion means an irradiated field covered lesions contoured from CT-Simulation which may generally less than 20cm, include 4-5 vertebra bodies, sacrum plus adjacent iliac lesions or a segment of femerol bone. Each patient can only have one index lesion for this study.
  • Index lesion with bone destruction either osteolytic or osteoblastic in nature as assessed on CT or MRI imaging
  • If the nature of the metastatic disease has been previously documented, the index lesion to be treated does not require further documentation (i.e., biopsy)
  • ≥ One primary painful metastatic site. The most painful site that need treatment first will be elected as index lesion site for evaluation of response. Additional less painful metastatic sites may be present. Patients who elect to have another course of RT treatment on different metastatic sites after the initial treatment are allowed.
  • Worst pain in the last 24 hours must be ≥ 4 on a 0-10 numeric scale.
  • Index lesion causing clinical or radiographic evidence of partial spinal cord or cauda equina compression/effacement is allowed.
  • Have developed pain or have persistent pain while on a stable chemotherapy, hormonal therapy, target therapy or bisphosphonate therapy regimen is allowed. There will be no change of chemotherapy, hormonal therapy, or bisphosphonate therapy for 4 weeks before and after radiotherapy
  • ECOG performance status 0-3
  • Life expectancy ≥ 3 months
  • Patients with impending fracture of weight bearing bone or patients with symptoms of spinal cord compression should have surgical opinion before the start of radiotherapy. Patient should not be able to be enrolled in this study if surgery is scheduled.

Exclusion Criteria:

  • Index lesion involves the skull
  • Index lesion has evidence of a pathologic fracture, impending fracture need immediate surgery are not eligible. Those patients had received decompression surgery are not eligible.
  • Has undergone prior radiotherapy at the index lesion
  • Those who chemotherapy or systemic treatment will be changed during study period.
  • Patients had history of metal implant inside or outside irradiation field are not eligible .
  • Patients had history of pacemaker insertion due to arrhythmia are not eligible.
