- INTRODUCTION: Recent advances in the treatment for esophageal cancer have improved the prognosis after esophagectomy, but they have led to an increased incidence of gastric tube cancer. In most patients who underwent retrosternal reconstruction, median sternotomy is performed; it is associated with a risk of postoperative bleeding and osteomyelitis, and pain often negatively affects respiration. Here, we report the first case of thoracoscopic retrosternal gastric conduit resection in the supine position (TRGR-S). MATERIALS AND SURGICAL TECHNIQUE: A 75-year-old male patient was placed in the supine position. Four ports were placed in the left chest wall. The gastric tube was separated from the epicardium, sternum, and left brachiocephalic vein. Because of adhesions between the gastric tube and the right pleura, combined resection of the right pleura was performed. The dorsal side of the gastric tube was dissected before the ventral side, enabling the gastric tube to be suspended from the back of the sternum and, thus, making it easier to expose the surgical field. Next, pedicled jejunal reconstruction via the presternal route was performed. There were no postoperative complications. The pathological diagnosis was signet ring cell carcinoma (pT1b, pN0, M0, pStage I), indicating R0 resection. DISCUSSION: TRGR-S does not require sternotomy, reducing the risk of postoperative bleeding and osteomyelitis. In the presence of adhesions, TRGR-S is safe and provides a good surgical view. It is also reliable procedure for resection of retrosternal gastric tube cancer, and it is ergonomic for surgeons.2020年07月, Asian journal of endoscopic surgery, 13(3) (3), 461 - 464
- Abstract Bone marrow‐derived mesenchymal stem or stromal cells (MSC) have been shown to be recruited to various types of tumor tissues, where they interact with tumor cells to promote their proliferation, survival, invasion and metastasis, depending on the type of the tumor. We have previously shown that Ror2 receptor tyrosine kinase and its ligand, Wnt5a, are expressed in MSC, and Wnt5a‐Ror2 signaling in MSC induces expression of CXCL16, which, in turn, promotes proliferation of co–cultured MKN45 gastric cancer cells via the CXCL16‐CXCR6 axis. However, it remains unclear how CXCL16 regulates proliferation of MKN45 cells. Here, we show that knockdown of CXCL16 in MSC by siRNA suppresses not only proliferation but also migration of co–cultured MKN45 cells. We also show that MSC‐derived CXCL16 or recombinant CXCL16 upregulates expression of Ror1 through activation of STAT3 in MKN45 cells, leading to promotion of proliferation and migration of MKN45 cells in vitro. Furthermore, co–injection of MSC with MKN45 cells in nude mice promoted tumor formation in a manner dependent on expression of Ror1 in MKN45 cells, and anti–CXCL16 neutralizing antibody suppressed tumor formation of MKN45 cells co–injected with MSC. These results suggest that CXCL16 produced through Ror2‐mediated signaling in MSC within the tumor microenvironment acts on MKN45 cells in a paracrine manner to activate the CXCR6‐STAT3 pathway, which, in turn, induces expression of Ror1 in MKN45 cells, thereby promoting tumor progression.Wiley, 2020年02月, Cancer Science, 111(4) (4), 1254 - 1265

- Collective invasion is an important strategy of cancers of epithelial origin, including colorectal cancer (CRC), to infiltrate efficiently into local tissues as collective cell groups. Within the groups, cells at the invasive front, called leader cells, are highly polarized and motile, thereby providing the migratory traction that guides the follower cells. However, its underlying mechanisms remain unclear. We have previously shown that signaling emanating from the receptor tyrosine kinase Ror2 can promote invasion of human osteosarcoma cells and that intraflagellar transport 20 (IFT20) mediates its signaling to regulate Golgi structure and transport. Herein, we investigated the role of Ror2 and IFT20 in collective invasion of CRC cells, where Ror2 expression is either silenced or nonsilenced. We show by cell biological analyses that IFT20 promotes collective invasion of CRC cells, irrespective of expression and function of Ror2. Intraflagellar transport 20 is required for organization of Golgi‐associated, stabilized microtubules, oriented toward the direction of invasion in leader cells. Our results also indicate that IFT20 promotes reorientation of the Golgi apparatus toward the front side of leader cells. Live cell imaging of the microtubule plus‐end binding protein EB1 revealed that IFT20 is required for continuous polarized microtubule growth in leader cells. These results indicate that IFT20 plays an important role in collective invasion of CRC cells by regulating organization of Golgi‐associated, stabilized microtubules and Golgi polarity in leader cells.Wiley, 2019年02月, Cancer Science, 110(4) (4), 1306 - 1316
