- Grade 3 tumors show significant abnormalities and usually correspond to a poor prognosis.
Thus, a proper histological grading is vital. It assists in predicting patient outcomes and customizing treatment.
Tumor Staging
Tumor staging refers to how far cancer has spread in the body. It is usually done using the TNM system, which evaluates:
- T (tumor size and extent)
- N (lymph node involvement)
- M (metastasis or spread to other organs)
Staging helps determine the severity of the disease. For instance, early-stage tumors (Stage I) usually have a better prognosis compared to advanced-stage tumors (Stage IV). As a rule, more advanced staging correlates with lower survival rates. Tumor staging is critical for treatment planning.
Molecular Markers
Molecular markers are genetic or protein changes found in cancer cells. These markers provide insight into how the cancer is likely to behave or respond to treatment. Various studies have identified specific genetic alterations that may impact prognosis. For example, certain mutations in the TP53 gene are associated with a poorer outcome in leiomyosarcoma patients.
