[Results] Tongue cancer (10 patients) was found to have the poorest prognosis among all the subsites, and especially those who had recurrence within 3 months after previous surgery had extremely poor prognoses; 30% (3/10) of them died without being discharged from the hospital after salvage surgery, and in 40% of them QOL was remarkably impaired losing their voice and chance of peroral food intake, etc. While T classification and N classification of initial and recurrent tumors were found to have no correlations with the prognosis. [Conclusion] More appropriate and realistic information should be provided to those patients to assist them to make a fully informed decision prior to surgery., 長崎大学学位論文 学位記番号:博(医歯薬)乙第48号 学位授与年月日:平成29年6月7日, Author: Shinya Jinnouchi, Kenichi Kaneko, Fujinobu Tanaka, Katsumi Tanaka, Haruo Takahashi, Citation: Acta Medica Nagasakiensia, 60(3), pp.119-124; 2016, Nagasaki University (長崎大学), 博士(医学) (2017-06-07)}, school = {Nagasaki University (長崎大学)}, title = {Surgical outcomes in cases of postoperative recurrence of primary oral cancer that required reconstruction}, year = {2017} }
