Applications Routine histology procedures including Immunohistochemistry (IHC) and In Situ Hybridization (ISH), protocols which can be found at our support page.
Notes 1. TMA slides were sectioned and stored at 4°C and may not be fresh cut, but still suitable for IHC. Please request fresh cut if experiment involves phospho-specific antibodies, RNA studies, FISH or ISH, etc. A minimum of 3 slides per TMA must be purchased to cover the cost of trimming for fresh sectioning. 2. Most TMA slides were not coated with an extra layer of paraffin (tissue cores can be easily seen on the glass). To prevent tissue detachment during antigen retrieval, unbaked slides must be baked for at least 30 to 120 minutes at 60°C. before putting into xylene for de-paraffinization. Baked slides were sent out baked for 2 hours.

TNM grading:

AJCC-TNM classification for mucosal melanoma of the head and neck

T3 Mucosal disease
Primary Tumour
T3Mucosal disease
T4a Moderately advanced disease. Tumour involving deep soft tissue, cartilage, one, or overlying skin.
T4bVery advanced disease. Tumour involving brain, dura, skull base, lower cranial nerves (IX, X, XI, XII), masticator space, carotid artery, prevertebral space or mediastinal structures
Regional lymph nodes
NXRegional lymph nodes cannot be assessed
N0No regional lymph node metastases
N1Regional lymph node metastases present

Clinical stage
Stage IIIT3N0M0
Stage IVAT4aN0M0

Stage IVBT4bAny NM0
Stage IVCAny TAny NM1

Vulvovaginal mucosal melanoma
Vulval melanomas are staged using the same AJCC-TNM classification as the table above. There is no staging system for vaginal melanoma, so a simplified clinical staging system can be used to categorise these melanomas.
Vaginal melanoma
Stage IClinically localized disease
Stage IIRegional nodal involvement
Stage IIIDistant metastatic involvement

Anorectal mucosal melanoma
Anorectal mucosal melanoma is staged using the same simplified staging system as vaginal melanoma.
Anorectal mucosal melanoma
Stage IClinically localized disease
Stage IIRegional nodal involvement
Stage IIIDistant metastatic involvement
Melanoma of the skins
Primary tumor (T)
* TX: Primary tumor cannot be assessed (e.g., shave biopsy or regressed melanoma)
* T0: No evidence of primary tumor
* Tis: Melanoma in situ
* T1: Tumor 1.0 mm or less in thickness with or without ulceration
  * T1a: Tumor 1.0 mm or less in thickness and Clarks level II or III, no ulceration
  * T1b: Tumor 1.0 mm or less in thickness and Clarks level IV or V or with ulceration
* T2: Tumor more than 1.0 mm but not more than 2.0 mm in thickness with or without ulceration
  * T2a: Tumor more than 1.0 mm but not more than 2.0 mm in thickness, no ulceration
  * T2b: Tumor more than 1.0 mm but not more than 2.0 mm in thickness, with ulceration
* T3: Tumor more than 2.0 mm but not more than 4 mm in thickness with or without ulceration
  * T3a: Tumor more than 2.0 mm but not more than 4 mm in thickness, no ulceration
  * T3b: Tumor more than 2.0 mm but not more than 4 mm in thickness, with ulceration
* T4: Tumor more than 4.0 mm in thickness with or without ulceration
  * T4a: Tumor more than 4.0 mm in thickness, no ulceration
  * T4b: Tumor more than 4.0 mm in thickness, with ulceration


Regional lymph nodes (N)

* NX: Regional lymph nodes cannot be assessed
* N0: No regional lymph node metastasis
* N1: Metastasis to 1 lymph node
  * N1a: Clinically occult (microscopic) metastasis
  * N1b: Clinically apparent (macroscopic) metastasis
* N2: Metastasis to 2 or 3 regional nodes or intralymphatic regional metastasis without nodal metastases
  * N2a: Clinically occult (microscopic) metastasis
  * N2b: Clinically apparent (macroscopic) metastasis
  * N2c: Satellite or in transit metastasis without nodal metastasis
* N3: Metastasis in 4 or more regional nodes, or matted lymph nodes, or in transit metastasis or satellite(s) with metastatic regional node(s)
Note: Micrometastases are diagnosed after elective or sentinel lymphadenectomy; macrometastases are defined as clinically detectable lymph nodes metastases confirmed by therapeutic lymphadenectomy, or when any lymph node metastasis exhibits gross extracapsular extension.
Distant Metastasis (M)
* MX: Distant metastasis cannot be assessed
* M0: No distant metastasis
* M1: Distant metastasis
  * M1a: Metastasis to skin, subcutaneous tissues, or distant lymph nodes
  * M1b: Metastasis to lung
  * M1c: Metastasis to all other visceral sites or distant metastasis at any site associated with an elevated serum lactic dehydrogenase (LDH)
