Percutaneous ablation of bone tumors

Diagnostic and Interventional Imaging, 2014
Percutaneous ablation (radiofrequency or cryotherapy) of bone tumors is most often performed for palliative purposes. Many studies have shown that percutaneous ablation of a painful bone metastasis can significantly and sustainably reduce symptoms. It is therefore an alternative to radiotherapy and to long-term opiates.

Design and Implementation of a Navigation System for Laparoscopic Tumor Ablation based on Intraoperative US [PDF]

, 2016
Laparoscopic ablation of liver tumors using ultrasound (US) guidance is a challenging task as it depends on the ability to mentally reconstruct the 3D spatial relationships between the tumor and the ablation needle from 2D ultrasound images. In this work

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Unscented Kalman Filtering for Real Time Thermometry During Laser Ablation Interventions

, 2022
International audienceWe present a data-assimilation Bayesian framework in the context of laser ablation for the treatment of cancer. For solving the nonlinear estimation of the tissue temperature evolving during the therapy, the Unscented Kalman Filter (

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Hemoglobin-loaded hollow mesoporous carbon-gold nanocomposites enhance microwave ablation through hypoxia relief

Journal of Nanobiotechnology
Microwave ablation, as a critical minimally invasive technique for tumor treatment, remains challenging in achieving an optimal balance between incomplete and excessive ablation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Thermal Ablation of Lung Tumors: Focus on Microwave Ablation [PDF]

RöFo - Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren, 2017
Background Image-guided thermal ablation can be used for the treatment of medically inoperable primary and metastatic lung cancer. These techniques are based on the heating up or freezing (cryoablation) of a volume of tissue around a percutaneous applicator that induces necrosis of the tumor.

Activity-based cost analysis of hepatic tumor ablation using CT-guided high-dose rate brachytherapy or CT-guided radiofrequency ablation in hepatocellular carcinoma. [PDF]

, 2016
PURPOSE To analyse and compare the costs of hepatic tumor ablation with computed tomography (CT)-guided high-dose rate brachytherapy (CT-HDRBT) and CT-guided radiofrequency ablation (CT-RFA) as two alternative minimally invasive treatment options of ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
