Introduction
The tumor stage refers to the size and depth of the tumor at its primary site. Invasive cancer is a pathological characteristic indicating that tumor cells have penetrated the normal tissue barriers and spread into surrounding tissues. However, it cannot directly reflect critical information such as tumor size, lymph node involvement, or the presence of distant metastasis; therefore, it cannot be used in staging systems.
In general, invasive carcinoma is a pathological characteristic that does not determine tumor size or metastasis status, and therefore cannot be used to establish cancer staging. The details are as follows:
Tumor stage refers to the size and depth of the tumor at its primary site. Invasive carcinoma, on the other hand, describes the condition in which tumor cells have penetrated normal tissue barriers and spread into surrounding tissues. It does not directly reflect critical information such as tumor size, lymph node involvement, or the presence of distant metastasis; thus, it cannot be used within standard staging systems.
Although patients with grade 3 invasive carcinoma may exhibit some degree of local lymph node metastasis and invasion of surrounding tissues, this does not mean the patient falls into a specific cancer stage. Instead, treatment planning and prognosis assessment for lung cancer should take multiple factors into account—including molecular characteristics of the tumor, the patient’s age, and overall health—through comprehensive evaluation.
