Overview
If left untreated, cutaneous T cell lymphoma may progress to develop cutaneous patches, plaque, and tumors. Depending on the extent of the lymphoma at the time of diagnosis, the prognosis may vary.
Natural History
- The symptoms of mycosis fungoides usually develop in the first nonspecific, indolent inflammatory such as : topic dermatitis, nonspecific chronic dermatitis, or parapsoriasis ( large-plaque parapsoriasis).[1]
- The majory of patients have early stage (77.9% : IA stage IA 38.8%, stage IB 39.1% ), patietns with satge IIB diagnosed in 5.5% and stage III observed in 6.6%.[1]
- The majority of patients of mycosis fungoides are not diagnosed and end stage not be observed.[1]
- Mycosis fungoides in early stage characterized with nonspecific dermatitis or consists patches observed on the lower trunk and buttocks.[1]
- Mycosis fungoides is initially an indolent lymphoma that may later develop peripheral lymphadenopathy and can finally progress to widespread visceral involvement.[2]
- Cutaneous T cell lymphoma is usually initially seen by dermatologists with patients presenting with skin lesions such as erythematous patches or plaque.
- Patients often have a history of several years of eczematous or dermatitic skin lesions before the diagnosis is finally established.
- The skin lesions then progress from the patch stage to the plaque stage to cutaneous tumors.
Complications
- Common complications of Cutaneous T cell lymphoma include:
- Mycosis Fungoides increased risk of secondary malignancies such as primary malignancy, especially Hodgkin lymphoma, chronic leukemia, and lung cancer.[3]
- [Complication 2]
- [Complication 3]
Prognosis
- Cutaneous T cell lymphoma is usually a slow-growing (indolent) lymphoma.[4]
- The prognosis for people with cutaneous T cell lymphoma is based on the extent of disease and how the person responds to treatment.
- Although more advanced stages of cutaneous T cell lymphoma may not be cured, the lymphoma can still be controlled with treatment.
Favorable prognosis
Unfavorable prognosis
- More advanced disease
- Lymphoma has spread to lymph nodes
- Lymphoma has spread to other organs
Staging
- The staging of cutaneous T cell lymphoma is based on skin and lymph node involvement.[4]
- Staging for cutaneous T cell lymphoma(Mycosis fungoides (MF) and Sezary syndrome have same critera for staging) is provided in the following table:[5][6]
| 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][7]
| 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
