How to avoid consequences after brachytherapy?
Contact radiological irradiation of a cancerous tumor is a type of radiation therapy. The technique is to introduce a special microcapsule with a radioactive isotope into the malignant neoplasm. Consequences and complicationsafter brachytherapy, mainly associated with relapse, dysfunction of the affected organ and necrotic alteration of nearby tissues. Consider the side effects after the procedure in more detail.
General recommendations for patients
After the operation, patients are recommended to adhere to a special diet and refrain from emotional and physical overload. In addition, operated patients should undergo a physical examination every month. Rehabilitation period, as a rule, ends in six months.
Possible consequences of the procedure
This procedure may be accompanied by local and general complications. At the local level, patients may have dysfunction of the irradiated organ and inflammatory processes in nearby structures.
The general consequences, as a rule, are related to the incorrect calculation of the dose of radioactive radiation. As a result, the patient may have individual symptoms of radiation sickness.
PSA after brachytherapy
After carrying out such therapy, the concentration of psa-oncomarker can not go down to zero. This is due to the preservation of epithelial cells, albeit in a damaged state. Normally, doctors consider the PCA value to be up to 1 ng / ml. Excess of such boundary figures is regarded as a relapse of cancer.
In practice, there is often a situation where the concentration of the marker rises to, ng / ml for the first three years after radiological intervention. This phenomenon was called the "leap of a dog." Patients in this case do not worry - this is a normal physiological process, which does not indicate a relapse.
In oncourology, the repeated formation of a malignant neoplasm is considered to be a multiple increase in the oncomarker in excess of 1 ng / ml after achieving its dynamic equilibrium. Confirmation of the oncologic diagnosis requires a biopsy.
Complications and side effects
In most cases, the implantation of radioactive elements is carried out with oncological lesions of the prostate gland. The main complications of such interference arise in the following forms:
- Urinary incontinence. This condition is a rather rare consequence and occurs in 1-3% of operated patients. Enuresis is associated with the previous partial resection of the prostate, which is accompanied by the removal of the internal sphincter. The external valve is weakened due to the radiological impact.
- Acute urinary retention, which is observed in 5% of cancer patients. This dysfunction, as a rule, is spontaneously eliminated after 2 to 3 months after brachytherapy.
- Structures of the urethra- narrowing of the urinary tract. This damage relates to late complications of the procedure, since it can be formed after 5 to 7 years.
How to avoid the consequences after the treatment of cancer brachytherapy?
For successful therapy in this technique, the patient must carefully approach the choice of an oncological clinic. In this issue, special attention is paid to the method of monitoring the progress of the operation. Most oncological centers brachytherapy intervention is carried out under the supervision of ultrasound. Only a small number of specialists have an international certificate, which allows computer tomography during manipulation.
Immediately before the operation, the patient must undergo the following training:
- Purification of the gastrointestinal tract.
- Ultrasound examination and magnetic resonance imaging.
- A common and expanded blood test.
- Radiography of the chest.
Upon completion of the procedure, the patient should follow specific recommendations for complete rehabilitation.
Oncology in the first month after the operation is prohibited:
- Lifting weight more than five kilograms.
- Exposed to active physical or emotional stress.
- To be in a sitting position longer, - 2 hours.
- Eat fried, salty or peppery foods.
- A long time is in a state of overflow of the intestine or bladder.
During the rehabilitation period, the patient should regularly monitor the level of PSA. Negative adverse events after the course of treatment are kept under control only if the patient is satisfied with the schedule of preventive visits to the oncologist.
What to expect after brachytherapy?
After this treatment, a person, in practice, does not feel uncomfortable sensations and will soon return to normal life.
The constant procedure of implantation of the radiocapsule causes the presence of radiation in the body. Such patients in the first few months are not recommended to contact pregnant women and children. The intensity of radiation gradually decreases and is completely absent for 5 to 6 months. The implantable capsule is not removed, it does not cause any complications or discomfort.
Recurrence of cancer after brachytherapy
In oncology practice, there is a possibility of developing a repeated malignant process in the zone of local irradiation. This may be due to improper diagnosis or an inadequate dose of radiation. The formation of a relapse, as a rule, is accompanied by a sharp increase in the PSA tumor marker.
Repeated oncology requires the appointment of hormone regulating therapy and surgical excision of oncoforming. Prevention of relapse consists exclusively in periodic examinations and the delivery of analysis for tumor markers..
