A controversial issue with some studies suggesting no benefit and others a "possible" benefit

However patients that do have debulking surgery may  have the advantage of a less extensive DXT field with less tissue damage  so overall it may be beneficial in selected cases

As a general rule all malignant tumors that do not have significant radio/ chemo sensititivity should taken for debulking. This is beneficial to the patient asit leads to cytoreduction, decreased tumor load and better management of the residual disease.

However it may not always be possible to debulk the malignant tumors especially the thymic , due high vascularity, and being adherent/ invading the surrounding vital structures especially the pulmonary artery and aorta.
