Radiation treatment delivery, >/=1 MeV; complex
CPT4 code
Name of the Procedure:
Radiation Treatment Delivery, ≥1 MeV; Complex
Common name(s): Complex Radiation Therapy, High-Energy Radiation Therapy
Summary
Radiation treatment delivery, ≥1 MeV; complex, involves the use of high-energy radiation to target and destroy cancerous cells in the body. It is a sophisticated and precise therapy aimed at treating tumors that are difficult to reach or require intensive targeting.
Purpose
This procedure is used to treat various types of cancers by damaging the DNA of cancer cells, thereby inhibiting their ability to grow and divide. The goal is to eliminate or reduce the size of the tumor while minimizing damage to surrounding healthy tissues.
Indications
- Tumors located in hard-to-reach areas
- Advanced or aggressive cancers
- Cancers that have not responded to other treatments
- Cancers that require highly precise targeting due to proximity to vital organs
Preparation
- Consultation with an oncologist and a radiologist
- Pre-treatment imaging studies (CT, MRI, PET scans)
- Simulation session to map out treatment coordinates
- Marking of the treatment area on the skin if necessary
- Instructions may include fasting or medication adjustments depending on the tumor location
Procedure Description
- The patient lies on a treatment table in a fixed position.
- Imaging systems are used to align and verify the precise target area.
- The high-energy radiation machine (linear accelerator) directs beams at the tumor from multiple angles.
- The machine may rotate around the patient to deliver radiation doses accurately.
- Constant monitoring and adjustment ensure the radiation is concentrated on the target area.
- No anesthesia or sedation is typically required.
Duration
Each session typically lasts between 15 to 30 minutes, with the actual radiation delivery taking only a few minutes. Treatments are usually given over several weeks.
Setting
The procedure is performed in a hospital or specialized outpatient radiation therapy clinic.
Personnel
- Radiation oncologist
- Medical physicist
- Radiation therapist
- Nurse
Risks and Complications
- Fatigue
- Skin irritation and damage
- Nausea
- Changes in appetite
- Rare risks: Damage to nearby organs, secondary cancers
Benefits
- Non-invasive treatment option
- Precisely targets cancer cells, sparing surrounding healthy tissue
- Can shrink or eliminate tumors
- Benefits typically realized within a few weeks to months post-treatment
Recovery
- Regular follow-up appointments
- Report any side effects to your healthcare provider
- Skin care instructions for the treated area
- Maintain a healthy diet and stay hydrated
- Recovery times vary; some side effects may persist for weeks after treatment
Alternatives
- Surgery: Direct removal of the tumor, which may be more invasive.
- Chemotherapy: Uses drugs to kill cancer cells, but may have more systemic side effects.
- Immunotherapy: Boosts the body’s natural defenses, but not suitable for all cancer types.
- Pros and Cons: Alternatives may be less precise but can be combined with radiation for comprehensive treatment.
Patient Experience
During the procedure, patients need to remain still but should feel no pain. Some minor discomfort from lying in a fixed position might occur. Post-procedure, patients may experience fatigue and skin changes. Comfort measures include pain management and skin care routines.
