Overview of Recurrence of Tumor

In general, the recurrence rates for benign parotid tumors that are correctly and completely removed during the initial surgery are very low.

The recurrence rates for malignant tumors depends on the type of malignant tumor, as some malignant parotid tumors can recur locally in the salivary gland, spread to lymph nodes, or spread to other parts of the body.

The most important consideration for a patient is to make sure that they have a skilled and experienced surgeon performing their surgery.

The capsules of parotid tumors are very thin. The inside of the capsule is filled with granules of tumor cells. It is important for the surgeon to keep that capsule intact during the surgery to prevent the tumor cells from spilling into the parotid gland.

Some malignant tumors may not have a defined capsule, and some benign tumors have tumor cells that extend beyond the capsule. It is crucial that the surgeon performing this surgery has the experience necessary to properly handle tumors with and without a capsule.

A patient should have a discussion with their surgeon regarding the likelihood of having a recurrence based on the parotid tumor type, and the success of the surgery.

Patients should have a clear understanding of the type of surveillance or follow up plan that is required after surgery.
