✦ Synopsis

One frequent area of uncertainty in assigning proper staging categories is the use of the “X” suffix when assigned to the tumor (T), lymph node (N), or metastasis (M) categories of the TNM classification system. When X is used, patients ordinarily cannot be assigned a stage, e.g., Stage III. The objective of this communication was to clarify the use of X.
