Controversy over surgical treatment of clinically negative neck in early stage oral squamous cell carcinoma revolves around the uncertainty of its impact on patient prognosis. The efficacy of elective neck dissection on prognosis in T1, 2 N0M0 patients continues to be the subject of clinical debate. Currently the clinically negative patients are treated by one of the two main policies: one is elective neck dissection; the other is "watchful waiting". The objective of this multi-institutional prospective randomized controlled study is to evaluate the survival benefit of elective neck dissection on the prognosis of T1, 2 N0M0 patients with carcinoma of oral cavity. The enrolled patients with T1, 2 N0M0 oral cancer will be randomized into two groups: elective neck dissection versus watch and wait. The survival rate and the recurrence rate between two groups would be compared. The result of the study will give surgeons evidence-based instructions for the management of clinically negative neck in patients with cancer of oral cavity.

Further study details as provided by Sun Yat-sen University:

Primary Outcome Measures:
  • Whether elective neck dissection (END) has equal or higher survival rate to the wait and watch policy [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
    The 5-year's survival and the disease free survival of the two group of patients are being measured and compared with one and other, so the survival benefit of the two policy is evaluated.

Secondary Outcome Measures:
  • Does END have the equal or lower recurrence rate to the wait and watch policy [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
    The recurrence includes recurrence of the primary tumor and the neck, and it's measured by clinacal examination, MRI examination and ultrasonic inspection.

  • quality of life [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
    The quality of life of patients after surgery is measured by UW-QOL.

Estimated Enrollment: 448
Study Start Date: April 2011
Estimated Study Completion Date: December 2021
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: elective neck dissection Procedure: elective neck dissection
patient underwent elective neck dissection as initial treatment, along with the excision of the primary tumor
Other Name: superior omohyoid neck dissection, SOHND
No Intervention: wait and see Procedure: watch and wait
at the first time of surgery, no intervention of the neck is taken, but with close monitoring, once the sign of metastasis appears, therapeutic neck dissection is to be taken
Other Names:
  • wait and see
  • watchful waiting
