Ameloblastomas are benign tumors of odontogenic epithelial origin. There is a high incidence of local recurrence associated with these tumors, and distant metastasis is rare. A review of the English literature shows that there have been 41 prior reports of pulmonary metastases from ameloblastomas of the oral cavity. We present another case of ameloblastoma metastatic to the lung and review the histopathology and mechanism of metastatic spread.

Background: The Arp2/3 complex is a key regulator of tumor metastasis, and targeting its subunits offers potential for anti-metastatic therapy. However, the expression profiles, prognostic relevance, and diagnostic value of its subunits across cancers remain poorly understood. This study aims to investigate the clinical relevance of Arp2/3 complex subunits, particularly ARPC1A, in pan-cancer, and to further analyze the potential biological mechanisms of ARPC1A, as well as its association with immune infiltration and chemotherapy drug sensitivity.

Unlabelled: Cancer-associated fibroblasts (CAFs) have been shown to play a crucial role in the progression of non-small cell lung cancer (NSCLC). Exosomes derived from CAFs have emerged as important mediators of intercellular communication in the tumor microenvironment, contributing to cancer progression. Therefore, it is essential to further investigate the mechanisms by which CAF-derived exosomes regulate NSCLC.

Pancreatic carcinoma has remained one of the leading causes of cancer-related mortality worldwide. Cancer originating in the head of pancreas is often detected early in the disease due to biliary obstruction resulting in jaundice. In contrast, cancer of the pancreatic body and tail remains indolent, presenting late with significantly increased tumor burden and distant metastasis.

Introduction: Intestinal lymphoma may be latent in some dogs with chronic inflammatory enteropathy. Mesenchymal stromal cells (MSCs) have potential therapeutic applications for refractory chronic inflammatory enteropathy, but their impact on the development of potential intestinal lymphomas has not yet been evaluated. Therefore, this study was performed to investigate the effect of canine adipose-derived MSCs (cADSCs) on the growth of canine lymphoma cell lines to assess the safety of MSC-based therapy in terms of pro- and anti-tumorigenic effects.

Background: Circulating tumor cells and clusters (CTC) from soft-tissue sarcoma (STS) that become entrapped in the lung can form micro-metastases and lead to pulmonary metastatic disease. Many patients with localized high-risk STS later develop metastases. Radiation is effective at reducing local recurrence by eradicating microscopic infiltration and satellites in the reactive zone surrounding the primary tumor.
