Preferred Label : Stage IV Mycosis Fungoides AJCC v7;
NCIt synonyms : Mycosis Fungoides Stage IV; Stage IV Mycosis Fungoides;
NCIt definition : Stage IV includes: IVA1 (T1-4, N0-2, M0, B2); IVA2 (T1-4, N3, M0, B0-2); IVB (T1-4,
N0-3, M1, B0-2). T1: Limited patches, papules, and/or plaques covering less than 10%
of the skin surface. May further stratify into T1a (patch only) vs. T1b (plaque /-
patch). T2: Patches, papules, or plaques covering 10% or more of the skin surface.
May further stratify into T2a (patch only) vs. T2b (plaque /- patch). T3: One or
more tumors (equal or greater than 1 cm diameter). T4: Confluence of erythema covering
80% or more of body surface area. N0: No clinically abnormal peripheral lymph nodes;
biopsy not required. N1: Clinically abnormal peripheral lymph nodes; histopathology
Dutch grade 1 or NCI LN0-2. N2: Clinically abnormal peripheral lymph nodes; histopathology
Dutch grade 2 or NCI LN3. N3: Clinically abnormal peripheral lymph nodes; histopathology
Dutch grades 3-4 or NCI LN4; clone positive or negative. M0: No visceral organ involvement.
M1: Visceral involvement (must have pathology confirmation and organ involved should
be specified). B0: Absence of significant blood involvement: 5% or less of peripheral
blood lymphocytes are atypical (Sezary cells). B1: Low blood tumor burden: more than
5% of peripheral blood lymphocytes are atypical (Sezary cells) but does not meet the
criteria of B2. B2: High blood tumor burden: 1000/microL Sezary cells or more with
positive clone. (AJCC 7th ed.);
