Stage I is divided into 2 subgroups IA or IB depending on the thickness of the melanoma and whether a pathologist sees ulceration under a microscope.

The earliest stage melanomas are stage 0 melanoma in situ and then range from stages I 1 through IV 4. Measurement is rounded to the nearest 01 mm. Doctors also use a cancers stage when talking about survival statistics.

This noninvasive stage is also called melanoma in situ. 14 January 2019 Sentinel Lymph Node Biopsy Guideline 2 Introduction Sentinel node biopsy SNB has been at the forefront of the surgical staging of melanoma patients for the past 15 years. Melanomas in the range of 075 to 084 mm are reported as 08 mm hence T1b.

Many of these issues are unsettled because of conflicting evidence. The goal is that melanomas of the same stage will have similar characteristics treatment options and outcomes. Survival of patients with early invasive melanoma down-staged under the new eighth edition of the American Joint Committee on Cancer staging system.

The high accuracy of this prognostic staging procedure is now recognised in all international guidelines for melanoma. 08 mm thickness with ulceration or 08 – 10 mm thickness with or without ulceration. The SEER database tracks 5-year relative survival rates for melanoma skin cancer in the United States based on how far the cancer has spread.

Gershenwald JE Scolyer RA Hess KR. Find out what a dermatologist says about each melanoma stage from the most curable to the most deadly. Tumor thickness measurements now are recorded to the nearest 01mm not the nearest 001 mm.

The cancer is smaller than 1 mm in Breslow depth and may or may not be ulcerated. The SEER database however does not group cancers by AJCC TNM stages stage 1 stage 2 stage 3 etc. The primary melanoma is still only in the skin and is relatively thin.

As a rule the lower the number the less the cancer has spread. The guidelines on diagnosis treatment and follow-up of cutaneous melanoma were released on September 30 2019 by the European Society for Medical Oncology ESMO 1.

Diagnosis relies on a skilled practitioner with the aid of dermoscopy and initial local surgical management is a mainstay of treatment. Melanoma is an increasingly common cancer in the United States although mortality has likely stabilized. Instead it groups cancers into localized regional and distant stages.

The 8th edition staging also incorporates Breslow thickness into stage III disease 5-year melanoma-specific survival for AJCC 7th edition stage IIIA is 78 compared with 93 for AJCC 8th edition stage IIIA. The staging system is detailed in the AJCC Cancer Staging Manual released by the American Joint Committee on Cancer. The system assigns a stage based on tumor-node-metastasis TNM scores as well as additional prognostic factors.
