  Purpose

This randomized clinical trial studies dexamethasone in reducing oral pain and dry mouth after surgery in patients with oral cancer. Dexamethasone may help lower pain and dry mouth caused by surgery.

Primary Outcome Measures:
  • Pain visual analogue scale (VAS) score measured at 10-point scale [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    It will be measured at five time points (baseline, days 1, 2, 3 and 7-21 days after surgery). A descriptive time plot of VAS scores will be produced for all enrolled subjects, with loess curve fitted separately for the experimental and control groups. A linear mixed effects model will be used to compare the pain VAS scores between the experimental and control groups.


Secondary Outcome Measures:
  • Eating Assessment Tool (EAT)-10 scores [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    A descriptive time plot will be produced for EAT-10 scores using baseline and postoperative measurements on days 3 and day 7-21. Descriptive statistical analyses will be conducted for a summary of EAT-10 scores at baseline, days 3 and day 7-21 after surgery. A linear mixed effects model will be used to compare the EAT-10 scores between the two groups.

  • Length of hospital stay (number of days between the date of surgery and date of discharge) [ Time Frame: Up to 21 days ] [ Designated as safety issue: No ]
    Kaplan-Meier functions will be fitted to compare the length of hospital stay between the experimental and control groups.

  • Narcotic pain medication usage [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    A descriptive statistical analysis will be conducted on narcotic pain medication use. A summary of these secondary endpoints will be reported separately for the experimental and control groups.

  • Type of diet tolerated [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    A descriptive statistical analysis will be conducted on type of diet tolerance. A summary of these secondary endpoints will be reported separately for the experimental and control groups.

  • Need for tube feeds [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    A descriptive statistical analysis will be conducted on the need for tube feeds. A summary of these secondary endpoints will be reported separately for the experimental and control groups.

  • Time to the initiation of oral intake [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    Kaplan-Meier curves will be plotted for time to the initiation of oral intake.

  • Complications associated with postoperative corticosteroid use after TORS [ Time Frame: Up to 12 months ] [ Designated as safety issue: No ]
    Descriptive statistical analyses will be conducted for a summary of VAS scores at baseline, days 1, 2, 3 and day 7-21 after surgery

Detailed Description:

PRIMARY OBJECTIVES:

I. To prospectively determine if a longer 4-day course of dexamethasone (or equivalent) for the management of postoperative pain and dysphagia following transoral robotic surgery (TORS) is superior to the current standard of a single injection of dexamethasone 10 mg.

SECONDARY OBJECTIVES:

I. Determine the effect of postoperative corticosteroids on postoperative dysphagia following TORS.

II. Determine the effect of postoperative corticosteroids on length of hospital stay following TORS.

III. Determine the complications associated with postoperative corticosteroid use after TORS.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive dexamethasone intravenously (IV) at the time of surgery and orally (PO) every 8 hours for up to 4 days following surgery.

ARM II: Patients receive dexamethasone IV at the time of surgery and placebo PO every 8 hours for up to 4 days following surgery.

After completion of study treatment, patients are followed up for up to 12 months.
