What is malignant melanoma Clark Level 2?

Clark’s Level II: Penetration by melanomas into the second layer of the skin, the dermis. Clark’s Levels III-IV: Melanomas invade deeper through the dermis, but are still contained completely within the skin.

Which stage of melanoma has the best prognosis?

Five-Year Survival Rate by Melanoma Stage:

  • Localized melanoma: Stage 0, Stage I, and Stage II: 98.4%
  • Regional melanoma: Stage III: 63.6%
  • Metastatic melanoma: Stage IV: 22.5%

What percentage of Stage IV melanoma patients will survive five years?

What does Stage 2 melanoma mean?

In Stage II melanoma, the cancer cells are in both the first layer of skin—the epidermis—and the second layer of skin—the dermis. The melanoma is higher risk than Stage I, either due to depth of tumor or presence of ulceration, but there is no evidence the cancer has spread to lymph nodes or distant sites (metastasis).

Can you survive Stage 5 melanoma?

For people with “thin melanoma,” defined as being less than 1 millimeter in maximal thickness, that has not spread to lymph nodes or other distant sites, the 5-year survival is 99%. However, for people with thicker melanoma, the 5-year survival may be as low as 80%.

When to use Clark’s levels for melanoma prognosis?

There is one instance in which Clark’s levels may be used to predict prognosis—in patients with thin (less than 1.0 mm) melanoma. Even then, it is only used as a default if the mitotic rate of the thin melanoma cannot be determined.

How big is Stage 2 melanoma on the skin?

The melanoma is only in the skin and there is no sign that it has spread to lymph nodes or other parts of the body.

Find out what Clark and Breslow staging means for melanoma skin cancer. The stage of a melanoma describes how deeply it has grown into the skin, and whether it has spread. Doctors use 2 scales to describe how deeply the melanoma has gone into the skin.

What are the survival rates for melanoma Stage 1?

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. The SEER database, however, does not group cancers by AJCC TNM stages (stage 1, stage 2, stage 3, etc.).
