What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at the best way to treat people with p53-mutant oral dysplasia (abnormal cells in the mouth) and early-stage oral cancer. About 636 adults will be placed into three groups based on their diagnosis and receive either monitoring, surgery, or surgery plus neck dissection. The goal is to see which approach best prevents the disease from getting worse or coming back.
