COMBINED METHOD FOR TREATING LOCALLY DISSEMINATED FORMS OF THYROID GLAND CARCINOMA AND ITS RECURRENCES Russian patent published in 2006 - IPC A61N5/10 

FIELD: medicine.

SUBSTANCE: method involves applying intraoperative radiation therapy with rapid electrons of 6 MeV with single dose of 8 Gray per removed tumor bed. Then, postoperative remote gamma-therapy course is applied after having healed the wound and removing sutures to postoperative suture region and regional lymph discharge zone at a dose of 2 Gray with 5 fractions per week. The number of remote gamma-therapy sessions is calculated from formula N=8.8(3.4-X^-0.169), where N is the number of postoperative remote gamma-therapy sessions; X is the time interval length in days between the intraoperative radiation therapy session and remote gamma-therapy session under condition that mixed irradiation dose (intraoperative radiation therapy and remote gamma-therapy) to thyroid gland tumor region or cancer recurrence area is equal to 60 Gray in terms of isoeffect.

EFFECT: increased total course dose per tumor focus; reduced risk of relapse; accelerated treatment course.
