Stages of esophageal cancer are assigned based on The American Joint Committee on Cancer’s (AJCC) TNM system, a commonly accepted method based on 3 key components:
1. Tumor (T) describes the size of the original tumor.
2. Node (N) indicates whether the cancer is present in the lymph nodes.
3. Metastasis (M) refers to whether cancer has spread to other parts of the body.
A number (0-4) or the letter X is assigned to each factor. In esophageal cancer staging, as in all cancer staging, a higher number indicates increasing severity.
Anatomic categories include T descriptors (tumor invasion), N descriptors (regional lymph node invasion), and M descriptors (distant site). Non anatomic categories include grade differentiation (G descriptors) and tumor location (L descriptors). Category descriptors are currently assessed by endoscopy with biopsy, by endoscopy ultrasound fine-needle aspiration (EUS-FNA), by thoracic-abdominal-pelvic computed tomography (CT), and whole body flurodeoxyglucose positron emission tomography (FDG-PET) fused with CT.
More tests are being done and we will keep you updated. For the full story read on 2 sections below under background information.
