What
This treatment is based on image-guided localization. A common practice is to perform simulation localization and fuse CT/MRI (PET if necessary), delineate the tumor and critical organs, develop a plan, verify it, and then implement irradiation in fractions, with image correction and body position fixation before each treatment. Monitor skin, bowel and bladder reactions, and blood counts during treatment. The above is general health information and not medical advice; the specific plan is subject to specialist evaluation and hospital protocol.
How
- Perform CT/MRI or PET image simulation localization.
- Develop and verify the irradiation plan and then implement it in fractions.
- Image correction and body position fixation before each treatment.
- Monitor skin, bowel and bladder reactions, and blood count changes.
Recovery
Fatigue, local skin reactions, or bowel and bladder irritation symptoms may occur during treatment, which are mostly manageable short-term reactions. Follow up according to the plan, and review images to assess efficacy and side effects. Generally, it does not affect flying, but if symptoms are obvious or sedation is required, consult a doctor first; pay attention to skin care and sufficient hydration.
- Pay attention to managing fatigue and skin reactions.
- Follow-up review of images to assess efficacy and side effects.
- Consult a doctor to ensure skin care and adequate hydration.
FAQ
Will the treatment hurt?
Radiation therapy itself is usually painless, but body position fixation or complications may cause discomfort. Tell the team if you experience pain or abnormal bowel movements so they can be treated.
Why is there such a large cost difference?
It is related to fractionation, plan complexity, frequency of image guidance, and whether sedation or additional imaging examinations are required. The final cost is subject to hospital assessment and quotation.
How many irradiations are generally needed?
The fractionation varies depending on the plan. SBRT is mostly a few high doses, and IMRT is mostly multiple moderate doses. The doctor will combine the lesion and the tolerance of the risk organs to develop a specific fractionation.
Will it cause hair loss or affect fertility?
Pelvic radiation therapy usually does not cause systemic hair loss, but may cause local hair changes and reproductive-related risks. It is necessary to discuss contraception and fertility plans with the doctor before treatment.
Will metal implants affect radiation therapy?
Metal will affect dose calculation and image quality. Physicists will use correction and plan optimization; please provide implant information for evaluation.
Is it necessary to carry out chemotherapy at the same time?
Some pathologies will consider synchronous or sequential systemic therapy. Whether to combine depends on the pathology, staging, and physical condition, and is determined by a multidisciplinary team.
