77605 Hyperthermia, externally generated; deep (ie, heating to depths greater than 4 cm)

Name of the Procedure:

Hyperthermia, externally generated; deep (heating to depths greater than 4 cm)

Summary

Hyperthermia treatment utilizes elevated temperatures generated externally to target and treat tissues deep within the body, specifically reaching depths greater than 4 cm. This procedure is often used alongside other cancer treatments to improve their efficacy.

Purpose

Hyperthermia aims to treat cancerous tumors by increasing the temperature of specific areas of the body, thereby making cancer cells more susceptible to radiation and chemotherapy. The expected outcome is a reduction in tumor size and enhanced effectiveness of accompanying treatments.

Indications

Hyperthermia is indicated for:

• Localized tumors that are challenging to treat with standard radiation or chemotherapy alone.
• Recurrent cancers where other treatment options have failed.
• Specific types of soft tissue sarcomas, breast cancer, cervical cancer, and head and neck cancers.

Preparation

Patients may need to:

• Follow specific dietary restrictions or fasting guidelines prior to the procedure.
• Undergo imaging tests such as MRI or CT scans to identify the precise location and size of the tumor.
• Adjust their current medications under the guidance of their healthcare provider.

Procedure Description

1. The patient is positioned comfortably, and the targeted area is identified.
2. An external applicator that emits radiofrequency or microwave energy is placed over the treatment site.
3. Gradual and controlled heating is applied, monitored through thermometers or imaging techniques to ensure the correct temperature is reached.
4. Cooling methods may be incorporated to protect surrounding healthy tissues.
5. The temperature is maintained for about 30-60 minutes, typically in combination with radiation or during chemotherapy sessions.
6. The procedure might be repeated multiple times over several weeks.

The tools used include external applicators, thermometers, imaging devices, and cooling systems. Depending on the setup, local anesthesia or sedation may be administered to ensure patient comfort.

Duration

Each session typically takes about 1 to 1.5 hours, with the heating phase lasting approximately 30-60 minutes.

Setting

The procedure is usually performed in a hospital's radiology or oncology department, or in specialized outpatient clinics equipped for hyperthermia therapy.

Personnel

• Oncologists or radiologists specializing in hyperthermia treatment.
• Nurses to assist in the procedure and monitor patient vital signs.
• Technicians to operate and calibrate the equipment.
• An anesthesiologist if sedation is required.

Risks and Complications

Common risks include:

• Skin burns or blisters in the treated area.
• Pain or discomfort during the procedure.
• Swelling or inflammation.

Rare complications may involve:

• Damage to nearby tissues or organs.
• Infection at the treatment site.
• Cardiovascular stress, particularly for patients with pre-existing heart conditions.

Benefits

The expected benefits include:

• Enhanced effectiveness of chemotherapy or radiation therapy.
• Potential reduction in tumor size.
• Improved overall treatment outcomes.

These benefits can often be realized immediately following the procedure but may become more pronounced with continued treatment sessions.

Recovery

Post-procedure care includes:

• Monitoring the treated area for any adverse reactions or complications.
• Applying topical treatments if skin irritation occurs.
• Following specific instructions on wound care if necessary.

Recovery time is typically short, with most patients resuming normal activities within a day. Follow-up appointments are crucial for assessing treatment efficacy and planning additional sessions.

Alternatives

Alternative treatments include:

• Surgery to remove the tumor.
• Sole reliance on radiation or chemotherapy without hyperthermia.
• Emerging therapies such as immunotherapy.

Each alternative comes with its pros and cons; for example, surgery might offer a more immediate resolution but with more significant recovery time and risks.

Patient Experience

During the procedure, patients might experience warmth or mild discomfort in the treated area. Pain management strategies, such as local anesthesia, sedation, or pain relief medications, ensure patient comfort. Post-procedure, patients can expect some localized soreness or skin reactions, which are generally manageable with appropriate care.
