A squamous cell carcinoma found on the lateral border of the tongue was classified as Stage II. What is the approximate 5-year survival rate for the patient?

The classification of a squamous cell carcinoma located on the lateral border of the tongue as Stage II indicates that the tumor has grown beyond the primary site but has not spread to distant parts of the body. In general, Stage II cancers typically have a five-year survival rate that can range from approximately 50% to about 70%, depending on various factors including tumor size and depth of invasion.

For oral squamous cell carcinoma specifically, research and statistical data provide evidence that the five-year survival rate for Stage II tends to be around 66%. This statistic reflects the balance between effective treatment options available and the potential for local recurrence or metastasis. The prognosis can improve substantially with early detection and appropriate management, making the Stage II classification a critical factor in understanding the likely outcomes for patients. Thus, stating that the survival rate is about 66% accurately captures the general expectations for patients diagnosed at this stage.
