1. Indications

The procedure of hyperthermia generated by interstitial probe(s) is indicated for the treatment of various tumor types, particularly when they are located deep within the body. The following conditions may warrant the use of this procedure:

• Deep-seated tumors Tumors located in organs such as the lungs or abdominal cavity that are not easily accessible through traditional surgical methods.
• Enhancement of radiation therapy Patients undergoing radiation treatment who may benefit from increased tumor sensitivity to radiation through elevated temperatures.
• Support for chemotherapy Tumors that may respond better to chemotherapy when combined with hyperthermia, potentially improving treatment outcomes.
• Immune system stimulation Conditions where stimulating the immune response against tumor cells is desired, as elevated temperatures may aid in this process.

2. Procedure

The procedure for hyperthermia generated by interstitial probe(s) involves several critical steps to ensure effective treatment. Each step is designed to maximize the therapeutic effects while minimizing risks to surrounding healthy tissue.

• Step 1: Patient Preparation The patient is first prepared for the procedure, which includes obtaining informed consent and ensuring that they are under appropriate anesthesia to minimize discomfort during the treatment.
• Step 2: Imaging Guidance Using imaging techniques such as x-ray or ultrasound, the physician identifies the precise location of the tumor. This step is crucial for the accurate placement of the interstitial applicators or probes.
• Step 3: Insertion of Applicators/Probes Once the tumor is located, the physician carefully inserts the interstitial applicators or probes into the tumor. This is done with precision to ensure that the heat will be effectively delivered to the targeted area.
• Step 4: Heat Application After the applicators or probes are in place, a heat source is introduced into them. The targeted area is then heated to the desired temperature, which is determined based on the specific treatment plan and the characteristics of the tumor.
• Step 5: Monitoring Throughout the procedure, the patient's vital signs and the temperature of the targeted area are monitored to ensure safety and effectiveness. Adjustments may be made as necessary to achieve optimal results.
• Step 6: Removal of Probes At the conclusion of the treatment session, the applicators or probes are carefully removed from the patient. Post-procedure care is then initiated as needed.

3. Post-Procedure

After the hyperthermia treatment, patients may require monitoring for any immediate side effects or complications. Common post-procedure care includes assessing the insertion sites for signs of infection or adverse reactions. Patients may experience localized discomfort or swelling, which can be managed with appropriate pain relief measures. Follow-up appointments are typically scheduled to evaluate the effectiveness of the treatment and to determine if additional sessions are necessary. It is essential for healthcare providers to provide patients with clear instructions regarding any activity restrictions or care requirements following the procedure to ensure optimal recovery and outcomes.
