Highly‐metastatic colorectal cancer cell released miR‐181a‐5p‐rich extracellular vesicles promote liver metastasis by activating hepatic stellate cells and remodelling the tumour microenvironment

The most common cause of CRC-related mortality is liver metastasis of colorectal cancer, and it is mainly caused by interactions between CRC cells and the tumor microenvironment in the liver. In turn, promoting CRLM, high-metastatic CRC cells produced more miR-181a/5p value EVs than cells with poor metastatic potential, according to the present report. High serum EV with miR-181a 5p was positively correlated with liver metastasis in CRC patients, according to the clinic. Taken together, highly metastatic CRC cells-derived EVs with a high in miR-181a5p could stimulate HSCs and restructure the TME, thus facilitating liver metastasis in CRC patients.

Tumor‐derived exosomes: Key players in non‐small cell lung cancer metastasis and their implication for targeted therapy

Lung cancer is the world's leading cause of cancer-related deaths, with 5year survival rates of about 7% in patients with distant metastasis. Although targeted therapy has improved the clinical outcomes of non-small cell lung cancer patients, nonsmall cell lung cancer's nonsmall cell lung cancer's survival has been greatly enhanced, however, drug resistance remains a major obstacle. Exosomes from tumor cells to their neighbor cells or cells at distant locations of the body can stimulate tumor microenvironment and facilitate tumor metastasis. Exosomal miRNAs are also used as noninvasive biomarkers for early diagnosis of lung cancer.

Neuregulin 1 (NRG1) fusion‐positive high‐grade spindle cell sarcoma: A distinct group of soft tissue tumors with metastatic potential

Neuregulin 1 is an epidermal growth factor that acts like a ligand that stimulates receptor tyrosine kinases of the ErbB family of receptors. All three tumors were high-grade spindle cell sarcomas composed of monomorphic spindle cells arranged in interlacing fascicles, histologically. The neoplastic cells exhibited ovoid to fusiform nuclei with finely stippled chromatin, insignificant nucleoli, scant, scant to moderately cytoplasmic vacuoles, occasional cytoplasmic vacuoles, and elongated cytoplasmic processes, with extending cytoplasmic processes, according to cytoplasmic cytoplasm, occasional cytoplasmic vacuoles, and etologically In both cases, the Cterminal EGFlike domain of NRG1 was preserved in the intended chimeric protein product. At the last follow-up, all three patients developed metastatic disease within two years from their initial presentation and were still suffering from the disease at the time. We summarize in this article the first case series of NRG1-rearranged sarcomas characterized by high-grade fascicular spindle cell morphology, non-specific immunoglobulation, and robust clinical behaviour. To determine if this particular subgroup of spindle cell sarcomas is amenable to targeted therapies, further research is needed.
