Overview
There are 3 classification methods used to classify cutaneous T cell lymphoma into several subtypes. Cutaneous T cell lymphoma may be classified into several subtypes based on WHO-EORTC classification.
Classification
According to world Health Organization (WHO) and European Organization for Research and Treatment of Cancer (EORTC) classification, mycosis fungoides may be classified into the following types:[1][2]
- Mycosis fungoides
- Mycosis fungoides variants and subtypes
- Folliculotropic mycosis fungoides
- Pagetoid reticulosis
- Granulomatous slack skin
Name | Description |
---|---|
Mycosis fungoides (MF) |
|
Staging
- The staging of cutaneous T cell lymphoma is based on skin and lymph node involvement.[3]
- Staging for cutaneous T cell lymphoma(Mycosis fungoides (MF) and Sezary syndrome have same critera for staging) is provided in the following table:[4][5]
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:[4][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 |
- [5-year disease free survival (DSS)]
- Cancer has spread to other organs in the body, including the blood and bone marrow
- Lymph nodes may be enlarged and may contain cancer
