Why do I say that when patients with lung cancer radiotherapy with hyperthermia effective

(1) systemic or local hyperthermia, the tumor cell necrosis decomposition, and its decomposition product can stimulate the immune system to play a role, thereby inhibiting the growth of tumor cells.
(2) The study found: high fever and with the use of radiotherapy can significantly reduce the radiation dose. Such as skin metastasis of breast cancer first partial heated to 44 ℃ ~ 46 ℃, 1 hour after radiotherapy, radiation dose can be reduced from 15Gy to 6Gy.
(3) high fever immediately after radiation therapy or radiotherapy immediately after the adoption of the whole body or partial heating method to raise the heat, are all effective ways to enhance the sensitivity of tumor to radiation, thereby enhancing the efficacy.
(4) tumor tissue after heating microcirculation blood flow was significantly lower than the pre-heated blood flow and lead to tumor cells with severe hypoxia, and when combined with radiotherapy heating, thermal destruction cytotoxicity and the direct killing effect of radiation complement each other, so that the tumor cells selectively add to the injury.
