This early phase I trial studies the effects of imiquimod 5% cream applied to the skin (topically) prior to standard of care surgery for the treatment of stage I-II oral cancer. Imiquimod is a drug that activates toll-like receptor in oral cancer cells causing self-destruction of tumor cells. It also activates immune cells to attack and eliminate cancer cells. Imiquimod applied topically prior to surgery may shrink oral cancer.

PRIMARY OBJECTIVE:
I. To assess the preliminary efficacy of topical imiquimod in neoadjuvant setting in patients with early-stage oral squamous cell carcinoma as determined by a minimum of 50% reduction in tumor assessed first by pathologic review and then confirmed with tumor cell count using quantitative immunofluorescence.
SECONDARY OBJECTIVE:
I. To assess local and systemic safety and tolerability by Common Terminology Criteria for Adverse Events (CTCAE) version (v)5 criteria.
EXPLORATORY OBJECTIVE:
I. To explore the effect of imiquimod on the tumor immune microenvironment (immune profile) by performing quantitative multiplex immunofluorescence.
OUTLINE:
Patients apply imiquimod topically 0.5-2 cm beyond the outlined tumor margins once daily (QD) on days 1-28 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days.
