Article Abstract
Objectives: To evaluate the effectiveness of follow-up with non-enhanced CT (NECT) in patients with breast cancer.
Methods: The present retrospective study included 1396 patients with breast cancer. Group A included patients with no metastasis to evaluate the diagnostic performance of NECT in detecting newly developed metastasis. Group B included patients with known hepatic metastasis to evaluate the accuracy of NECT for the assessment of hepatic metastasis.
Results: Group A included 895 patients (mean age 52.8 years). Among them, 145 patients had 160 metastases. The per-patient sensitivities for diagnosing newly developed metastasis were 68.3 and 53.8% according to the two reviewers, while the per-lesion sensitivities were 89.4 and 85.0%. Sensitivities for bone metastasis were 98.9 and 95.9%, while sensitivities for hepatic metastasis were 73.7 and 68.4%. In group B, the accuracy of hepatic metastasis response evaluation according to the RECIST criteria was 70.8% for reviewer 1 and 63.8% for reviewer 2.
Conclusions: NECT showed inadequate diagnostic performance in detecting newly developed metastasis and in evaluating the response of hepatic metastasis. However, NECT can be utilized as a follow-up modality in patients with decreased renal function or hypersensitivity to iodinated contrast media.
Advances In Knowledge: The risk of side effects of contrast media should be considered as important when NECT can be utilized as a follow-up modality in decreased renal function patients.

Colorectal cancer ranks among the most prevalent and lethal malignant tumors globally. Historically, the incidence of colorectal cancer in China has been lower than that in developed European and American countries; however, recent trends indicate a rising incidence due to changes in dietary patterns and lifestyle. Lipids serve critical roles in human physiology, such as energy provision, cell membrane formation, signaling molecule function, and hormone synthesis.

Purpose: This study aimed to evaluate the clinical efficiency and safety of hepatic arterial infusion chemotherapy (HAIC) combined with lenvatinib and programmed cell death protein-1 (PD-1) inhibitor for patients with hepatocellular carcinoma (HCC) and lung metastasis.
Methods: In this multicenter retrospective study, treatment-naive patients with advanced (BCLC stage C) HCC and lung metastases who received lenvatinib and PD-1 inhibitor - with or without HAIC - between January 2019 and January 2024 were reviewed. Propensity score matching (PSM) was applied to balance baseline characteristics between the two groups.

Purpose: Gallbladder squamous cell carcinoma (SCC) is a rare subtype of gallbladder malignancy, comprising only 1-4% of cases. Ectopic expression of β-human chorionic gonadotropin (β-hCG) has been described in various epithelial cancers and is associated with aggressive behavior. We report the first known case of gallbladder SCC with diffuse β-hCG expression and markedly elevated serum β-hCG levels, aiming to explore its clinicopathological implications and potential as a prognostic biomarker.

Introduction: Enfortumab vedotin plus pembrolizumab (EV + ) shows high efficacy in metastatic urothelial carcinoma (mUC), potentially increasing tumor lysis syndrome (TLS) risk.
Case Presentation: A 64-year-old man with mUC underwent surgery and adjuvant nivolumab after neoadjuvant chemotherapy. Five months post-surgery, EV + was initiated for recurrence with distant metastasis.

Purpose: To evaluate the efficacy and safety of computed tomography (CT)-guided co-ablation in patients with hepatic metastases from malignant melanoma.
Methods: Clinical data of 79 patients with hepatic metastases from malignant melanoma who underwent co-ablation (integration of cryoablation and thermal ablation) and programmed death 1 (PD-1) treatment between October 2019 and January 2024 were retrospectively analyzed. The patients were divided into group A (n = 50), patients who received co-ablation, and group B (n = 29), patients who received PD-1 treatment.
