Comparison of overall survival curves with elderly male patients according to the extent of lymphadenectomy and the presence of postoperative complications. Patients who underwent standard surgery had better prognoses than patients who underwent limited surgery (3-year overall survival: 78% vs. 72%, P = 0.186). However, patients who underwent limited surgery without developing postoperative complications tended to have a better prognosis than patients receiving standard surgery with postoperative complications (3-year overall survival: 78% vs. 55%, P = 0.156).
