The main questions it aims to answer are:\n\nDo patients who receive standard surgery with LND live longer without their cancer returning? Is adding LND safe, and how does it affect surgery-related complications? Researchers will compare the group receiving standard surgery plus LND to the group receiving standard surgery alone to see if adding LND is more effective.\n\nParticipants will:\n\nBe randomly assigned to one of the two surgical groups.
