Overview
The staging of cutaneous T cell lymphoma is based on skin and lymph node involvement.[1]
Staging
The staging of cutaneous T cell lymphoma is based on skin and lymph node involvement.[1] Staging for cutaneous T cell lymphoma is provided in the following table:[2][3][4]
| Staging for mycosis fungoides and Sezary syndrome | ||
|---|---|---|
| Skin (T) | ||
| T1 | Limited patches, papules, and/or plaques covering <10% of the skin surface. May further stratify into T1a (patch only) versus T1b (plaque patch) | |
| T2 | Patches, papules, or plaques covering 10% of the skin surface. May further stratify into T2a (patch only) versus T2b (plaque patch). | |
| T3 | One or more tumours (1-cm diameter) | |
| T4 | Confluence of erythema covering 80% body surface area | |
| Node (N) | ||
| N0 | No clinically abnormal peripheral lymph nodes; biopsy not required | |
| N1 | Clinically abnormal lymph nodes; histopathology Dutch grade 1 or NCI LN0-2 | |
| N1a | Clone negative | |
| N1b | Clone posetive | |
| N2 | Clinically abnormal peripheral lymph nodes; histopathology Dutch grade 2 or NCI LN3 | |
| N2a | Clone negatove | |
| N2b | Clone posetive | |
| N3 | Clinically abnormal peripheral lymph nodes; histopathology Dutch grades 3e4 or NCI LN4; clone positive or negative | |
| NX | Clinically abnormal peripheral lymph nodes; no histologic confirmation | |
| Visceral (M) | ||
| M0 | No visceral organ involvement | |
| M1 | Visceral involvement (must have pathology confirmation and organ involved should be specified) | |
| Blood (B) | ||
| B0 | 0 Absence of significant blood involvement: 5% of peripheral blood lymphocytes are atypical (Sezary) cells B0a Clone negative B0b Clone positive | |
| B1 | Low blood tumour burden: >5% of peripheral blood lymphocytes are atypical (Sezary) cells but does not meet the criteria of B2 B1a Clone negative B1b Clone positive | |
| B2 | High blood tumour burden: 1000/mL Sezary cells with positive clone | |
The staging of Sezary syndrome is based on the clinical stages:[5][6]
| clinical stages | |||||
|---|---|---|---|---|---|
| Stage | T | N | M | B | DDS |
| IA | 1 | 0 | 0 | 0/1 | 98 |
| IB | 2 | 0 | 0 | 0/1 | 89 |
| IIA | 1.2 | 1.2 | 0 | 0/1 | 89 |
| IIB | 3 | 0-2 | 0 | 0/1 | 56 |
| IIIA | 4 | 0-2 | 0 | 0 | 54 |
| IIIB | 4 | 0-2 | 0 | 1 | 48 |
| IVA1 | 1-4 | 0-2 | 0 | 2 | 41 |
| IVA2 | 1-4 | 3 | 0 | 0-2 | 23 |
| IVB | 1-4 | 0-3 | 1 | 0-2 | 18 |

- Summary of taging for cutaneous T cell lymphoma is provided in the following table:[1][2][3][4]
| Stage | Clinical description | Tomur (T) | Node (N) | Metastasis (M) | Blood (B) |
|---|---|---|---|---|---|
| IA | Limited patch or plaque <10% | T1 | N0 | M0 | 0-1 |
| IB | Generalized patch or pluque>10% | T2 | N0 | M0 | 0-1 |
| IIB | Tumors +/- adenophaty | T3 | N0-N2 | M0 | 0-1 |
| IIA | Patch or plaque + adenopathy | T1-T2 | N1-N2 | M0 | 1-2 |
| III | Erithroderma +/- adenopathy | T4 | N0-N2 | M0 | 0-2 |
| IVA | Histologically + nodes (Sezary syndrome) | T1-T4 | N0-N3 | M0 | 0-2 |
| IVB | Visceral involvement | T1-T4 | N0-N2 | M1 | 0-2 |
