Background: Distant metastasis from differentiated thyroid carcinoma at presentation is rare and isolated liver metastasis on presentation is almost unknown. We report a case of primary follicular carcinoma of the thyroid with isolated liver metastasis at presentation.
Case Presentation: A 65-year-old man of Kashmiri origin presented to our tertiary referral center with obstructive jaundice; he was evaluated with magnetic resonance cholangiopancreatography and positron emission tomography-computed tomography. Positron emission tomography-computed tomography documented a lesion in his liver in addition to a metabolically active thyroid nodule. Fine needle aspiration cytology of the liver lesion supplemented with immunohistochemical analysis using thyroid transcription factor 1 confirmed the lesion as being an isolated metastasis from the primary thyroid lesion (which on fine needle aspiration cytology showed follicular architecture).
Conclusions: To best of our knowledge, this is first reported case of primary differentiated thyroid carcinoma presenting with isolated liver metastasis manifesting as obstructive jaundice.

Folic Acid-Modified Milk Exosomes Delivering c-Kit siRNA Overcome EGFR-TKIs Resistance in Lung Cancer by Suppressing mTOR Signaling and Stemness.

The EGFR-TKIs (epidermal growth factor receptor-tyrosine kinases inhibitors) offer significant benefits to lung cancer patients with sensitive EGFR mutations; however, the development of acquired resistance poses a significant challenge and leads to poor prognosis. Thus, exploring novel therapeutic strategies to overcome EGFR-TKI resistance is urgently needed. This study introduces an innovative approach utilizing folic acid-modified milk exosomes loaded with c-kit siRNA (FA-mExo-siRNA-c-kit) to target EGFR-TKI resistance in lung cancer.

Tumor-associated macrophages (TAMs), which differentiate from tissue-resident macrophages, are recognized for their ability to influence cancer progression and metastasis. However, the specific role of Kupffer cells (KCs), the intrinsic macrophages of the liver, in the progression of hepatocellular carcinoma (HCC) remains unclear. In this study, we describe a novel mechanism by which exosomes derived from HCC cells induce KCs to transition into TAMs, thereby facilitating the metastasis of HCC in an IL6-JAK1-ACAP4 axis-dependent manner.

The aim of this study was to evaluate if the Ki-67 labeling index (LI) on immediate pre-ablation biopsies of colorectal liver metastases (CLM) is associated with the presence of viable tumor cells in subsequent ablation zone biopsies and/or local tumor progression-free survival (LTPFS). Biopsies of CLM were performed before and after microwave ablation (MWA), as part of a prospective clinical trial between October 2013 and May 2019. Pre-ablation biopsy slides were examined for the Ki-67 LI using light microscopy.

Background: Angiopoietin-2 (Ang-2) level is related to hepatocellular carcinoma (HCC) progression. However, the dynamic expression and regulatory mechanism of Ang-2 remain unclear.
Aim: To investigate Ang-2 levels in chronic liver diseases and validate early monitoring value with a dynamic model in hepatocarcinogenesis.

In this manuscript we comment on the article by Yang published recently, focusing on how hepatic angiopoietin-2 (Ang-2) transcription promote the progression of hepatocellular carcinoma (HCC). HCC is one of the most common and lethal malignancies worldwide, especially in regions with high hepatitis B virus infection rates. Ang-2 is a key mediator of angiogenesis and plays a significant role in the progression of chronic liver diseases towards HCC, particularly in the hypoxic microenvironment.
