Very Large Microwave Antenna #16 Used to Ablate Micro-Papillary Thyroid Cancer.
Too large for the neck. MWA antennas need to downside to at least #18-19 like RFA probes.
Ultrasound-guided percutaneous microwave ablation of solitary T1N0M0 papillary thyroid microcarcinoma: initial experience.
21 patients (six men and 15 women; age range, 29-81 years; mean, 52.1 ± 13.6 years) with 21 nodules of pathologically proven solitary papillary carcinoma < 10.0 mm (T1N0M0) were treated with MW ablation. All tumours were completely ablated at a single session and no serious or permanent complications occurred. No recurrence at the treatment site and no distant metastases were detected, with a mean follow-up of 11 months. Histological examination showed no evidence of a tumour in the treated lesions in eight patients. Follow-up ultrasound examinations showed disappearance of previously detected colour Doppler flow, as well as mass shrinkage, or both.Several cases of temporary hoarseness cleared by 3 montns.
During the short-term follow-up period, ultrasound-guided percutaneous MW ablation appears to be a safe and effective technique for solitary T1N0M0 papillary thyroid micro-carcinoma.
Large antenna too big for most thyroid work.
