Esophageal cancer progresses through several distinct stages that can impact treatment and prognosis.
Progression Stages of Esophageal Cancer
- Stage 0 (Carcinoma in Situ): Abnormal cells are found in the inner layer of the esophagus, but they have not invaded deeper layers.
- Stage I: Cancer has spread to the deeper layers of the esophagus but not to nearby lymph nodes.
- Stage IA: Tumor is less than 2 cm and has not spread to lymph nodes.
- Stage IB: Tumor is larger than 2 cm or has spread to the connective tissue but not lymph nodes.
- Stage II: Cancer may have spread to regional lymph nodes but not to distant organs.
- Stage IIA: Tumor is involved in muscle layers and may have spread to 1-2 lymph nodes.
- Stage IIB: Tumor is larger, has spread to more lymph nodes or may have spread to adjacent structures.
- Stage III: Cancer has spread to nearby tissues or lymph nodes.
- Includes IIIA, IIIB based on spread and size.
- Stage IV: Cancer has metastasized to distant organs, such as the liver, lungs, or bones.
- Stage IVA: Spread to nearby tissues.
- Stage IVB: Spread to more distant structures or multiple organ systems.
Statistical Overview of Stage Distribution
| Stage | Percentage of Cases |
|---|---|
| Stage 0 | 5% |
| Stage I | 25% |
| Stage II | 20% |
| Stage III | 30% |
| Stage IV | 20% |
