Materials And Methods: Between 1996 and 2020, 130 patients (82 men, 48 women) were treated with c-TACE, and 40 patients were additionally treated with thermal ablation. Survival was retrospectively analyzed using the Kaplan-Meier-method.
Article Synopsis
- The study assesses advancements in local treatments for breast cancer liver metastasis (BCLM) using techniques like laser interstitial thermotherapy (LITT), microwave ablation (MWA), and transarterial chemoembolization (TACE) from 1993 to 2020.
- Cox regression analysis indicates that various treatment methods significantly affect patient survival, with median survival times being longest for MWA and combined MWA+TACE treatments.
- Survival probabilities for LITT and MWA treatments show differing outcomes: LITT had a notable decline over time, whereas MWA had high initial survival rates, though its sample size was small and impacts future interpretations.

Purpose The purpose of the study is to retrospectively evaluate the development and technological progress in local oncological treatments of hepatocellular carcinoma (HCC) by means of ablation techniques like laser interstitial thermal therapy (LITT), microwave ablation (MWA) and transarterial chemoembolization (TACE) in a multimodal application. Method This retrospective single-center study uses data generated between 1993 and 2020 (1,045 patients). Therapy results are evaluated using survival rates of Kaplan-Meier estimator, Cox proportional hazard regression and log-rank test.

Aim: To assess the safety of ultrasound as a guide in ophthalmic blocks.
Methods: Fifty adult patients undergoing cataract surgery under peribulbar block anaesthesia were randomly assigned to ultrasound-guided and conventional block groups.
Purpose: To evaluate the overall survival (OS), local progression-free survival (PFS) and prognostic factors of patients with colorectal cancer liver metastases (CRLM) undergoing microwave ablation (MWA).
Method: A total of 132 patients were retrospectively enrolled who had been treated between 2010 and 2018. For the evaluation of survival rates, all patients were divided according to their indications (curative = 57 and debulking (patients with additional non-target extrahepatic metastases) = 75).
Objectives: To evaluate the outcomes of Trans Rectus Sheath Extra-Peritoneal Procedure (TREPP) in patients undergoing elective inguinal hernia repair.
Methods: In compliance with PRISMA statement standards, electronic databases were searched to identify all studies reporting the outcomes of TREPP in patients undergoing elective inguinal hernia repair. The outcomes of interest included recurrence, chronic pain, haematoma, and wound infection.
Objective: To determine the early treatment response after microwave ablation (MWA) of inoperable lung neoplasms using the apparent diffusion coefficient (ADC) value calculated 24 h after the ablation.
Materials And Methods: This retrospective study included 47 patients with 68 lung lesions, who underwent percutaneous MWA from January 2008 to December 2017. Evaluation of the lesions was done using MRI including DWI sequence with ADC value calculation pre-ablation and 24 h post-ablation.
