Features found on MRI may predict liver cancer recurrence after surgery
By Kate Madden Yee
An algorithm based on MRI features could help clinicians predict liver cancer recurrence after patients have undergone liver resection, researchers have found.

Preoperative axial extracellular contrast agent-enhanced (A-E) MRI and (F-H) follow-up CT images in a 71-year-old male patient with chronic hepatitis B and a serum neutrophil count of 4.2 × 109/L. A 5.6-cm mass with a 1.9-cm satellite nodule was detected in segments V and VIII. (A) The mass (asterisks, A-E) shows mild-to-moderate hyperintensity on T2-weighted images, (B) hypointensity on T1-weighted noncontrast-enhanced images, (C) less than 50% hyperenhancement on late arterial phase images, (D) nonperipheral washout and incomplete enhancing capsule on portal venous phase images, and (E) marked diffusion restriction on diffusion-weighted images (b = 800 sec/mm2). The mass was confirmed at histopathologic analysis as moderately differentiated hepatocellular carcinoma with microvascular invasion. With an advanced-stage recurrence after resection score of 19.8 points (4.2 + 5.6 + 10), this patient was assigned to the high-risk group (≥15 points) for advanced-stage recurrence. At follow-up, (F) noncontrast-enhanced, (G) arterial phase, and (H) portal venous phase CT images acquired at day 70 after surgery show multifocal intrahepatic recurrence and tumor thrombus in the left portal vein (black arrow, H).

PET predicts chemotherapy responses in breast cancer patients
By Will Morton
PET/CT with gallium-68 FAPI radiotracer can predict responses to neoadjuvant chemotherapy in breast cancer patients.

Representative Ga-68 FAPI-PET/CT images of 48-year-old woman who had left invasive ductal carcinoma and who achieved pathologic complete response (pCR). (A) Baseline maximum-intensity projection (MIP) image demonstrated primary lesion (red arrowhead; SUVmax, 26.72) and Ga-68 FAPI-avid lymph node in left axilla (red arrows). (B) MIP image after two cycles of neoadjuvant chemotherapy (NAC) showed that primary lesion (red arrowhead; SUVmax, 8.87) and axillary lymph nodes (red arrow) were reduced in size and radioactivity uptake. (C and D) Representative images of lab tissue staining for FAP before NAC showed strong FAP-positive staining in stromal cells (C), which was significantly decreased on tumor bed after six cycles of NAC (D).

20-year study shows that lung cancer screening boosts survival rates
By Kate Madden Yee
Diagnosing early-stage lung cancer with low-dose CT translates to a 20-year survival rate of 81%, according to a large-scale study.
November 7, 2023
(A, B) Two annual repeat low-dose CT scans in a woman who was 60 years old at baseline enrollment in 1999. At baseline enrollment, she was currently smoking and had a 30-pack-year smoking history. No nodules were identified on baseline low-dose CT scans. On the sixth annual low-dose CT scan (B), a right lower lobe solid nodule (arrow) measuring 4.5 mm in maximum diameter was identified. The nodule could be identified in retrospect on the prior annual CT scan (arrow in A), when it measured 2 mm in maximum diameter. Estimated tumor volume doubling time was 161 days. Lobectomy was performed two months later, and diagnosis of stage 1aN0M0 moderately differentiated adenocarcinoma measuring 6 mm in maximum diameter was made. Expert pathologic panel review (22) of the pathologic specimen updated the diagnosis to adenocarcinoma with mixed subtype (80% acinar, 20% bronchoalveolar carcinoma components) with 5 mm of invasion.
