Sentinel lymph node biopsy.

To have and make sure that inspection of "sentinel lymph node biopsy" at the time of surgery for gastric cancer, it can be determined almost certainly the presence or absence of lymph node metastasis of cancer, Kitagawa professors from Keio surgery was announced.
By ascertaining the exact transition, achievements to reduce the extent of resection, leading to a reduction of the aftermath, it was published in the American Journal of Medicine.
When the cancer to metastasize, sentinel lymph nodes, lymph node that cancer cells are washed ashore in the first through the lymphatic vessels. Sentinel means "lookout".
Inspection, injected into the cancer lesion substances which give a very small amount of radiation. At the time of surgery, were identified by detectors sentinel lymph nodes the material reaches to examine the presence of cancer pathology. It is possible to determine that there is no transition if there is cancer, to minimize the extent of resection.

That during surgery, to minimize the extent of resection and can check the lymph node metastasis It is also good news for patients. By all means, I want to hope that it will be available to establish the test early.


胃がんの手術時に「センチネルリンパ節生検」という検査を行い、がんのリンパ節転移の有無をほぼ確実に判断できることを確認したと、慶応大外科の北川教授らが発表した。
　転移を正確に見極めることで、切除範囲を減らし、後遺症の軽減につながる成果で、米医学誌に掲載された。
　センチネルリンパ節は、がんが転移する際に、がん細胞がリンパ管を通じて最初に流れ着くリンパ節のこと。センチネルは「見張り」を意味する。
　検査は、ごく微量の放射線を出す物質をがん病変部に注入。手術時に、この物質が到達したセンチネルリンパ節を探知機で特定し、病理検査でがんの有無を調べる。がんがなければ転移がないと判断し、切除範囲を最小限にとどめることが可能だ。
　手術中に、リンパ節転移を確認でき切除範囲を最小限にとどめることは患者さんにとっても朗報ですね。ぜひ、早期に検査を確立して利用できるようになることを期待したいですね。
