Strict protocol increases efficacy of CT screening for lung cancer
The true value of CT screening for lung cancer awaits results of the National Cancer Institute's National Lung Cancer Screening trial. But data from other smaller trials are available now to help guide use of CT for lung cancer screening. The findings from one of the largest trials to date, conducted by Italian researchers, were presented at the recent American Society of Clinical Oncology (ASCO) meeting.

MRI study indicates cognitive impairment after chemo for breast cancer
Breast cancer patients who have undergone chemotherapy were more likely to self-report cognitive impairment, and demonstrated neurological shifts on functional MRI (fMRI) tests, but these changes did not always translate to formal cognitive test results, according to a new study by researchers from London.

Hormone therapy, radiation reduce early-stage prostate cancer recurrence; yoga benefits breast cancer patients
ATLANTA - Data from seven randomized trials suggest that combining adjuvant hormonal therapy with radiotherapy will significantly reduce the risk of recurrence in patients with early-stage prostate cancer, while another study found that yoga may benefit women undergoing radiation therapy for breast cancer, researchers reported Sunday at the American Society of Clinical Oncology (ASCO) meeting.

Latest UFE studies show importance of both fibroid and particle size
NEW ORLEANS - Uterine fibroid embolization (UFE) studies presented this past weekend at the Society of Interventional Radiology (SIR) meeting drove home an important message: Fibroid volume, as well as the size of the spherical polyvinyl alcohol (SPVA) particles used in treatment, can determine the success of UFE.

Focal cryoablation promoted as new paradigm for treating prostate cancer
NEW ORLEANS - Focal cryoablation can target and treat prostate cancer while sparing healthy tissue, according to a presentation Friday at the Society for Interventional Radiology (SIR) meeting. Interventional radiologists in Florida used focal cryoablation to perform a "male lumpectomy" on prostate cancer patients.

RFA demonstrates 'surprising' efficacy for treatment of lung malignancies
NEW ORLEANS - What's good for the liver is good for the lung, according to results from a multicenter pilot trial of radiofrequency ablation (RFA). Italian investigators successfully used RFA to treat non-small cell lung cancer (NSCLC) in patients who were not candidates for surgery, external beam radiotherapy, and/or chemotherapy.

MRI finds breast cancers missed by mammography in high-risk women
CHICAGO - Results of the International Breast MRI Consortium (IBMC) Trial reinforce previous studies that suggest MRI can identify breast tumors missed by mammography, but the IBMC results are not the final word on the MRI-mammography debate, according to a presentation at the RSNA meeting on Wednesday.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).
