Although thoracic ablative therapies are generally safe procedures, fatal complications can occur. Bevacizumab is a standard-of-care treatment along with chemotherapy for metastatic colorectal cancer. Although uncommon, unpredictable serious adverse events can occur secondary to bevacizumab. We report a case of fatal intrapulmonary haemorrhage as a result of arteriopulmonary fistula in a patient after microwave ablation of pulmonary colorectal cancer metastasis while on bevacizumab. Antiangiogenetic properties of bevacizumab are associated with delayed wound healing, which might have been a crucial factor in the development of arteriopulmonary fistula and haemorrhage.

Objective: To compare the clinical outcomes between radiofrequency ablation (RFA) and microwave ablation (MWA) for the treatment of T1N0M0 papillary thyroid carcinoma (PTC) in a large cohort.

Materials And Methods: This retrospective study included 1111 patients with solitary T1N0M0 PTC treated with RFA (n = 894) or MWA (n = 215) by experienced physicians. A propensity score matching was used to compare disease progression, including lymph node metastases (LNM), recurrent tumors and persistent tumors, recurrence-free survival (RFS), volume reduction ratio (VRR), and complications between the RFA and MWA groups.

Circulating Tumor DNA Detection for Recurrence Monitoring of Stage I Non-Small Cell Lung Cancer Treated With Microwave Ablation.

Thorac Cancer

Department of Minimally Invasive Tumor Therapies Center, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, China.

Purpose: As microwave ablation continues to be used in patients with inoperable stage I non-small cell lung cancer (NSCLC), it is particularly important to monitor efficacy. Whether plasma ctDNA detection can predict its efficacy should be illustrated.

Methods: We recruited 43 patients with inoperative stage I NSCLC, all of whom underwent biopsy-synchronous microwave ablation (MWA).

This editorial comments on a study by Zuo . The focus is on the efficacy of hepatic arterial infusion chemotherapy combined with camrelizumab and apatinib (the TRIPLET regimen), alongside microwave ablation therapy, in treating advanced hepatocellular carcinoma (HCC). The potential application of this combination therapy for patients with advanced HCC is evaluated.
