Methods: One hundred and forty esophageal carcinoma patients were devided into two groups (A,B). A group (60 patients) was treated with conventional radiotherapy. B group(80 patients) was treated with conventional radiotherapy and intra-cavitary hyperthermia.
Conclusions:The terminal esophageal carcinoma treated by radiotheraphy and intra-cavitary hyperthermia improved local control rate and the 1-,3-,5- year survival rates, the recurrent rate of esophageal carcinoma was reduced.
[Purpose] To evaluate the tolerance, side effect, and local control rate for nasopharyngeal carcinoma(NPC) treated with radiotherapy combined with intracavity hyperthermia.
[Conclusions] Radiotherapy combined with intracavity hyperthermia was well tolerated in nasopharyngeal carcinoma patients and can improve local control rate, especially for patients with parapharyngeal space involvement.
Methods:91 cases of low rectal carcinoma were randomly divided into four groups: Group A included 19 cases treated with PRAC combined radiation, Group B included 30 cases treated with PEH combined radiation,Group C included 15 cases treated with preoperative radiotherapy,and Group D included 27 cases without any adjuvant therapy.
The thermal enhancement ratio of half shrink and disappearance of nasopharyngeal tumor was 1.68 and 1.39. Conclusions: Intracavitary thermotherapy plus radiotherapy is better than radiotherapy alone.
Objective: To explore the effect of preoperative endocavitary hyperthermia (PEH) combined with radiation on apoptosis and proliferation of cancer cells in lower rectum.
A randomized trial of intracavitary microwave hyperthermia combined with external irradiation (R+H) versus radiation (R) alone in the treatment of esophageal cancer was performed form February 1986 to February 1988.
The principle and construction of a microcomputer microwave cavity hypertherm are described, Applicator design, temperature measuring sensor in electromagnetic field, application of PID control adapted human cavity model are studied in this paper.
