Clinical Research Progress of Intensity Modulated Radiotherapy Imaging Guidance Technology Breast Conserving Surgery for Breast Cancer
Breast cancer is a common female malignant tumor in clinical practice,ranking first among female malignant tumors. Currently,there are many treatment methods for the disease actually,including surgery,radiotherapy,and chemotherapy. At present,breast conserving surgery may have recurrence and metastasis for breast cancer,and postoperative radiotherapy plays an active role in reducing local recurrence. Intensity modulated radiotherapy can have positioning errors for breast cancer after breast conserving surgery,which can increase radiation damage,cause radiation heart disease or radiation pneumonia,and even tumor control failure. With continuous progress of image-guided radiotherapy (IGRT) technology,various image-guided techniques have been widely used in clinical practice to correct precise radiotherapy positioning errors,locate accurately and treat local tumors effectively,and prevent incidence of radiation pneumonitis and cardiac injury to the greatest extent. The paper summarizes and analyzes the radiotherapy methods of breast cancer and understands its positioning errors,and discusses two-dimensional X-ray image guidance technology,optical body surface guidance technology and other related intensity modulated radiotherapy image guidance technologies after treatment of breast cancer,to provide reference for relevant research,and promote the continuous improvement and development of image guided technology for intensity modulated radiotherapy in breast conserving surgery for breast cancer.
