Pulmonary Tumor Ablation through Microwave: A Case Report

Introduction: Pulmonary metastases occasionally, do not respond to chemotherapy and surgery. Moreover, some low-grade stage cancer patients which spectaclesurgery indications, are not medically able to tolerate surgery. In such cases, microwave tumor ablation technique has convenient resulting in tumor destruction. This method includes a low morbidity and mortality rate compared with traditional cancer treatments. Also, lower procedural cost, the potential to perform in an outpatient setting and repeatability are the valuable aspects. Case Report: A 75-year-old man was clinically examined by an interventional pulmonologist, prior to microwave ablation. The medical history and physical examination details were documented. All index tumors were measured in three dimensions. The 68×48 mm pulmonary tumor arising from the pleura and close to the aorta was examined using computed tomography and magnetic resonance imaging, and biopsy confirmed the final diagnosis to be malignant adenocarcinoma. The patient received standard treatment. However, standard treatments failed and the tumor kept increasing in size despite chemotherapy. Microwave ablation was performed via an antenna that was guided from the side opposite to the tumor. New guidelines recommend the direct entry of the antenna in the tumor, to prevent probable pleural fistula. Current studies indicate that microwave ablation is a safe treatment modality for pulmonary malignancies and that it improves survival ofpatients who are unsuitable for surgery.
