Cases review
RECURRENCES, RECURRENCE, HEAD AND NECK CANCER
Cases of patients who undergo salvage surgery after the completion of the protocol treatment will be presented at the JCOG Head and Neck Cancer Study Group conference held every 6 months to review indications for surgery and the appropriateness of the surgical procedure. Cases with regional recurrence will be reviewed at the JCOG Radiation Therapy Study Group conference every 6 months to investigate whether the regional recurrences occur inside or outside the elective nodal sites. The RT plan, imaging data, and clinical course during the protocol treatment will be evaluated in each case.
