NED

  1. LND lymph node dissection
  2. NED no evidence of disease
  3. aThe surgery dates of these 12 patients range from October 1999 to December 2015, thus 6 patients were observed less than 36 months postoperatively
  4. bPatients who received chemotherapy were all treated with paclitaxel and carboplatin for 6 cycles. Patients underwent radiotherapy were given external- beam radiation therapy (EBRT) as 5040 cGy given as 28 fractions of 180 cGy
