After surgery, radiotherapy and chemotherapy for cervical cancer, some patients still have tumor recurrence or residual, which causes disease problems to patients and clinicians, and even poor prognosis. For cervical cancer recurrence and residual, the traditional treatment method is to increase the dose and course of radiotherapy, but such treatment is very likely to cause serious radiotherapy damage, such as radiation enteritis, vaginal-rectal fistula, pain and other sequelae, or tumor spread due to delayed treatment and poor efficacy. The reason is simple, because the recurrence of residual after radiotherapy has proved that radiotherapy is insensitive, so the traditional treatment can only be a helpless solution. After our clinical practice, it is confirmed that: radioactive particle implantation + ultrasonic focused knife minimally invasive treatment is a good method to treat cervical cancer recurrent residual. First of all, the high-intensity focused ultrasound knife uses the good focus of ultrasound and the permeability of energy to implement effective ultrasound irradiation to the tumor in the patient’s body and irreversibly kill the tumor cells by using instant local high temperature (70℃-110℃) without damaging the normal tissues. After ultrasonic knife treatment, when most of the tumor cells are killed and the tumor lacks blood supply, then particle implantation treatment method is used. Because the particles are directly implanted in the tumor, the killing effect is obvious, and at the same time, because of the close irradiation, the impact on the surrounding normal tissues is minimal. Therefore, the combined application of these 2 minimally invasive techniques for the treatment of recurrent residual cervical cancer has reliable effect, little side effects and short treatment time. Since it is a minimally (non-)invasive treatment, it is easily tolerated by patients. It can be applied even to older and weaker patients. Radioactive particle implantation + ultrasound focused knife minimally invasive treatment is a good method to treat recurrent residual cervical cancer and provides new hope for patients with recurrent residual cervical cancer.
