Objective: There is controversy among different guidelines regarding the use of thermal ablation to treat clinical T1a renal cell carcinomas with tumor sizes ranging from 3.1-4 cm. Therefore, we compared oncological outcomes between heat-based thermal ablation (hTA) and cryoablation (CA) in patients with solid T1a renal cell carcinomas, including those with a tumor size ≤3 cm and a tumor size of 3.

Purpose: To investigate the outcomes of first-line image-guided microwave ablation (MWA) plus tyrosine kinase inhibitors (TKIs) in untreated epidermal growth factor receptor (EGFR)-mutant advanced lung adenocarcinoma (LUAD) and to compare with TKIs alone.

Materials And Methods: This retrospective cohort study included patients between December 2015 and December 2021 and was divided into 2 groups (Group A: first-line MWA+TKIs; Group B: TKIs alone). Progression-free survival (PFS) was the primary end point, whereas overall survival (OS) was the secondary end point and were compared via the Kaplan-Meier methods.

Article Synopsis
  • - The study investigates how microwave ablation affects plasma proteomic changes in rabbit lungs with VX2 tumors, aiming to identify related molecular pathways.
  • - Blood samples were collected at five different time points before and after treatment, and plasma proteins were analyzed using advanced techniques, revealing different activated pathways at each time point.
  • - Key findings indicate that various pathways associated with tumor development, immune response, and metabolism were influenced by the microwave ablation treatment, suggesting potential impacts on cancer progression and chemotherapy sensitivity.

Background: CT-image segmentation for liver and hepatic vessels can facilitate liver surgical planning. However, time-consuming process and inter-observer variations of manual segmentation have limited wider application in clinical practice.

Purpose: Our study aimed to propose an automated deep learning (DL) segmentation algorithm for liver and hepatic vessels on portal venous phase CT images.

Background: The combination therapy of immunotherapy and drug-eluting bead bronchial artery chemoembolization (DEB-BACE) or microwave ablation (MWA) has been attempted as an effective and safe approach for advanced non-small cell lung cancer (NSCLC). However, the outcomes of immunotherapy plus multiple interventional techniques for advanced NSCLC remain unclear. This retrospective study thus aimed to investigate the effectiveness and safety of the maintenance treatment of programmed cell death protein 1 (PD-1) blockade after MWA plus DEB-BACE for advanced NSCLC.

Objectives: To evaluate the safety and efficacy of microwave ablation (MWA) for stage I non-small cell lung cancer (NSCLC) in patients with idiopathic pulmonary fibrosis (IPF).

Materials And Methods: A retrospective single-center cohort study was conducted in patients with clinical stage I NSCLC who underwent CT-guided MWA from Nov 2016 to Oct 2021. The patients were divided into the IPF group and the non-IPF group.

Purpose: To evaluate the safety and survival outcomes of computed tomography-guided microwave ablation (MWA) for medically inoperable Stage I non-small cell lung cancer (NSCLC) in patients aged ≥70 years.

Materials And Methods: This study was a prospective, single-arm, single-center clinical trial. The MWA clinical trial enrolled patients aged ≥70 years with medically inoperable Stage I NSCLC from January 2021 to October 2021.

Article Synopsis
  • This study evaluated the safety and effectiveness of using CT-guided fine-needle aspiration (FNA) before microwave ablation (MWA) for diagnosing pulmonary ground-glass nodules (GGNs).
  • The study found that while both FNA and core-needle biopsy (CNB) had similar positive diagnosis rates, using them sequentially significantly improved diagnostic performance.
  • Despite some minor complications like pulmonary hemorrhages, FNA before MWA was deemed reliable and did not affect the accuracy of the microwave antenna placement.

Purpose: To determine the effects of tract embolization with gelatin sponge particles on the prevention of pneumothorax after percutaneous microwave ablation (MWA) in rabbit lungs.

Materials And Methods: Twenty-four New Zealand white rabbits were randomly divided into Group A (MWA followed by tract embolization with gelatin sponge particles,  = 12) and Group B (MWA without tract embolization,  = 12). For each group, CT images were reviewed for the occurrence of pneumothorax within 30 min after MWA.

Circulating tumor DNA (ctDNA) detection holds promise for genetic analyses and quantitative assessment of tumor burden. A systematic review and meta-analysis were conducted to investigate the clinical relevance of ctDNA among patients with localized non-small cell lung cancer (NSCLC). PubMed, EMBASE, and the Cochrane Library were searched for eligible studies published from January 2001 to April 2022.

The study was designed to evaluate the efficiency of microwave ablation (MWA) in combination with anti-programmed death receptor 1 (anti-PD-1)/cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) in renal cell carcinoma (RCC) treatment. After tumors were established on C57/BL6 mice, MWA treatment and/or immune checkpoint inhibitor (ICI) treatment to the mice were performed. Tumor volume was recorded every 7 days.

Purpose: This study aimed to prove the hypothesis that neurolysis based on ethanol injection in combination with iodine-125 (I) radioactive seed implantation could prolong the nerve regeneration time compared with that based on ethanol injection alone. The grade of nerve injury was assessed for both methods.

Background: For non-small cell lung cancer (NSCLC) patients on antithrombotic therapy who are treated with microwave ablation (MWA), the transient interruption of antithrombotic agents may increase the risk of thromboembolism, and continuation of antithrombotic agents may increase the risk of intraprocedural hemorrhage. This retrospective cohort study aimed to explore the safety of MWA in patients with NSCLC on antithrombotic therapy.

Methods: A total of 572 patients with NSCLC (antithrombotic therapy group: n=84, Group A; control group: n=488, Group B) who received MWA were included.

Purpose: To compare the outcomes of drug-eluting bead bronchial arterial chemoembolization (DEB-BACE) with and without microwave ablation (MWA) for the treatment of advanced and standard treatment-refractory/ineligible non-small cell lung cancer (ASTRI-NSCLC).

Materials And Methods: A total of 77 ASTRI-NSCLC patients who received DEB-BACE combined with MWA (group A; n = 28) or DEB-BACE alone (group B; n = 49) were included. Clinical outcomes were compared between groups A and B.

Background: This study aimed to retrospectively explore the safety and feasibility of computed tomography (CT)-guided synchronous microwave ablation (MWA) followed by core-needle biopsy (CNB) via a coaxial cannula for highly suspected malignant lung ground-glass opacities (GGOs).

Methods: The clinical data of 66 patients (66 GGOs) treated with CT-guided synchronous MWA followed by CNB via a coaxial cannula from January 2019 to January 2021 were included in this study. The technical success rate, curative effect, and complications were evaluated.

Purpose: This retrospective study aimed to evaluate the safety and efficacy of microwave ablation (MWA) for lung malignancies in patients with severe emphysema.

Materials And Methods: The clinical records of 1075 consecutive patients treated for malignant lung tumors in our department were retrospectively reviewed. Emphysema was assessed based on standard-dose computed tomography (CT) and was considered severe when it occupied ≥25% of the lung.
