This article explores the benefits and drawbacks of RF Chemotherapy.

Definition: RF Chemotherapy involves using microwave energy in the Radio Frequency (RF) band, with appropriate power levels, to treat diseases, especially cancer.

The process is similar to RF ablation, as illustrated in Figure 1.

Advantages of RF Chemotherapy

Here are the key advantages of using RF Chemotherapy:

  • Reduced Side Effects: It effectively treats cancerous tumors located on the surface without causing the severe side effects associated with ionizing radiation and traditional chemotherapy.

  • Lower Power Requirements: It requires less microwave power because cancerous cells can be heated quickly. Furthermore, there’s less energy dissipation in soft tissues at greater depths, except near the skin’s surface.

  • Improved Patient Outcomes: RF Chemotherapy can extend a patient’s life by targeting and killing cancerous cells. It also alleviates the symptoms of various diseases, making it a valuable tool in cancer treatment.

  • Non-Invasive Procedure: It eliminates the need for surgical interventions on the patient’s body or body parts. This saves time and reduces costs, while providing significant relief to patients.

  • Technological Advancements & Availability: Advancements in RF technology have led to the development of more sophisticated equipment for RF chemotherapy. As a result, treatment services are becoming increasingly available in hospitals worldwide.

Disadvantages of RF Chemotherapy

While offering numerous benefits, RF Chemotherapy also has some disadvantages:

  • Power Sensitivity: If the RF power level is too high, it can damage the healthy tissue surrounding the treatment area.

  • Frequency Precision: The RF source’s signal frequency must be carefully set. Incorrect settings can reduce penetration depth while increasing resolution. Higher microwave frequencies result in higher resolution but lower penetration.

  • Requires Skilled Radiologists: RF chemotherapy requires skilled and experienced radiologists. It cannot be administered by individuals without proper training and knowledge of radiology.

  • Cost Considerations: In some hospitals around the globe, RF chemotherapy services can be expensive.

  • Hospital Setting Requirement: The treatment is not available for home administration. Patients must visit the hospital for each treatment session, adhering to the schedule prescribed by their doctors.
