ct2n2m1 refers to the clinical staging of the tumor, and the standardized writing is cT2N2M1.
Clinical staging and grading of malignant tumors are used to guide the treatment and prognosis of malignant tumors. At present, the international TNM method is often used for staging malignant tumors, with T representing tumor size and local infiltration range, N representing lymph node involvement, and M representing distant metastasis.
Tis for carcinoma in situ without infiltration, T1 for smaller primary site, T2 for larger primary site, T3 for larger primary site or infiltration beyond the primary organ, and T4 for very large primary site and/or infiltration into other neighboring organs.
N0 indicates that the tumor has no lymph node metastasis, N1 indicates that the tumor has limited lymph node metastasis, N2 indicates that the tumor has extensive lymph node metastasis, and N3 indicates that the tumor has more distant lymph node metastasis.
M0 indicates that the tumor has no bloodstream metastasis, and M1 indicates that the tumor has developed bloodstream metastasis.
