Radiotherapy for cervical tumors

Generally speaking, cervical cancer is diagnosed after a certain period of illness, which means it needs to be treated as soon as possible. Radiotherapy for cervical cancer is very common.

Radiotherapy is the first choice for cervical cancer and can be applied to cervical tumors of all stages. The radiation range includes the cervix and affected vagina, uterine body, paracervical tissue and pelvic lymph nodes. The radiotherapy method for cervical tumors generally adopts a combination of internal and external irradiation. Internal irradiation is mainly aimed at the primary lesion of the cervix and its adjacent areas, including the uterine body, upper part of the vagina and its adjacent paracervical tissue (point "A"). External irradiation is mainly aimed at the area where pelvic lymph nodes are distributed (point "B").

Internal radiation sources use intracavitary radium (Ra) or 137 cesium (137Cs), mainly targeting primary lesions in the cervix. External radiation sources use 60 cobalt (60Co), mainly targeting metastatic lesions outside the primary lesion, including the pelvic lymph node drainage area. The dose is generally 60Gy. At present, it is recommended to first perform internal irradiation for early cervical tumors. For advanced cancer, especially those with huge local tumors, active bleeding, or accompanied by infection, it is appropriate to first perform external irradiation.

Radiotherapy for cervical tumors is a commonly used treatment method for cervical tumors in clinical practice, and its therapeutic effect on tumors can be confirmed.
