  1. Abbreviations: IT Induction chemoradiotherapy followed by surgery, SA Surgery alone.
  2. Pathological effect; complete, viable tumor cells do not exist at all in the resected specimen; major, viable tumor cells remained in one-third of resected specimens; minor, viable tumor cells remained in more than one-third of resected specimens.
  3. *Significant difference was observed between major/minor and complete response cases (p = 0.012, Mann–Whitney U test) and between the SA and IT groups (p = 0.038).
