RFA joins arsenal for breast cancer metastases in the liver
In patients for whom surgery is not an option, percutaneous radio-frequency ablation offers a viable alternative for treating breast cancer metastatic disease in the liver.
In patients for whom surgery is not an option, percutaneous radio-frequency ablation offers a viable alternative for treating breast cancer metastatic disease in the liver.
Researchers from 12 centers participating in the tumor radio-frequency ablation Italian network (TRAIN) treated 102 patients with breast cancer, using the ablation technique. Under ultrasound or CT guidance, they applied RFA to tumors ranging from 0.8 to 5 cm in diameter. Results were presented at the 2004 RSNA meeting.
Using the Kaplan-Meier method, the researchers reported survival rates ranging from 95.2% at one year to 29.8% at five years. They completed RFA of tumors in 91.2% of the patients after 121 treatment sessions, and the primary effectiveness rate on a lesion-by-lesion basis was 86.9.
Can AI Enhance PET/MRI Assessment for Extraprostatic Tumor Extension in Patients with PCa?
December 17th 2024The use of an adjunctive machine learning model led to 17 and 21 percent improvements in the AUC and sensitivity rate, respectively, for PET/MRI in diagnosing extraprostatic tumor extension in patients with primary prostate cancer.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
