Recurrence of conventional radiation therapy of cervical cancer
Cervical cancer after treatment for the tumor has not disappeared not control, the treatment of tumors disappeared for a period of time after the original lesion in the region for a relapse. Two identification difficult, it called EC recurrence. Cervical cancer radiotherapy failure patients, nearly 60% of pelvic recurrence, 40% distant metastasis. In pelvic recurrence within 1 / 2 above pregnancy and pelvic recurrence.
[Diagnosis]
(1) Symptoms
1. Vaginal bleeding and vaginal discharge: This is the cervix, vagina and the Palace of recurrence common symptoms.
2. Pain and edema: This is the most common pelvic recurrence of the symptoms, the most affected is the lower extremity pain and edema.
(2) Signs
1. Recurrent cervical and vaginal: in the cervical or vaginal local stiffen, were nodular or even ulcers.
2. Palace of recurrence: sometimes can be increased and scheduling of the uterus.
3. Recurrent pregnancy: early pregnancy diagnosis of recurrence is extremely difficult, late pregnancy can usually nodular thickening or nodular lesions, the late, there will be frozen pelvis.
(3) auxiliary
1. Cervical, vaginal and the Palace of relapse may biopsy confirmed by histology.
2. Recurrent pregnancy can be pyelography, isotope kidney map, MRI and CT scans to assist diagnosis.
[Treatment]
Recurrence of treatment is very difficult. Right suspicious recurrence after treatment, in the absence confirmed, we must not lightly again radiotherapy, this will be the resumption of radiation injury. Recurrence is already diagnosed, the treatment should be based on the first, with the location and time of recurrence seriously consider re-treatment approach. If the first treatment for radiation therapy, in the Palace of recurrence, cervix, vagina or pregnancy (isolated nodules), surgical sites, treatment with the appropriate choice. Those deemed unsuitable for treatment, according to the tumor, treatment and the length of time between general factors such as patients decide to do radiation therapy or drug treatment. The case of a possible recurrence after surgery or radiation therapy medication, a few cases can be further surgery.
Cervical cancer recurrence radiotherapy for specific design, according to the recurrence of the location, extent determined. The case of the vagina, cervix, or Palace of the limitations of recurrence, can be considered purely intracavitary irradiation; If local recurrence of a broader scope, or associated with pregnancy and pelvic recurrence, should meet in vitro irradiation; The case of simple pregnancy or pelvic recurrence of the tumor can be located under the Wild, whose in vitro irradiation; If recurrence, according to the first radiotherapy treatment. Radiation therapy and relapse again after radiotherapy, the dose of irradiation difficult to grasp. Right from the first radiotherapy 2-3 years are to be considered under specific circumstances of giving full exposure. But first shorter recurrence after radiotherapy, the dose should be carefully decided to prevent indiscriminate irradiation, it is not a cure for cancer, the radiation would cause serious complications. The recurrence after radiotherapy for patients, tissue fibrosis, radiation sensitivity reduced through normal tissue and organ damage after a radiation exposure significantly increased complications.
[Follow-up]
1. Close follow-up after treatment, the treatment of attention to the original tumor, must also pay attention to whether a new lesions.
2. We should pay attention to the emergence of radiotherapy complications, early treatment.
