What is the current edition of the AJCC Staging Manual?

The 8th Edition Cancer Staging Manual brings together all the currently available knowledge on staging of cancer at various anatomic sites. This can be purchased as a hardcover or as a Kindle e-book. Chapter 1: Cancer Staging System provides overall rules for AJCC cancer staging that apply across all tumor sites.

What is considered a high mitotic rate in melanoma?

Melanomas with very high mitotic activity (≥10 mitoses/mm2) were predominantly thick and ulcerated nodular tumor subtypes.

What is the TNM classification system for staging cancer?

A system to describe the amount and spread of cancer in a patient’s body, using TNM. T describes the size of the tumor and any spread of cancer into nearby tissue; N describes spread of cancer to nearby lymph nodes; and M describes metastasis (spread of cancer to other parts of the body).

What is a good mitotic rate?

Conclusions: A mitotic rate of two or more mitoses per mm2 in cutaneous melanoma should be considered as a more accurate prognostic factor than one or more mitoses per mm2, particularly in tumors equal or greater than 0.8 mm in thickness.

1 to 4 per square millimeter.

What is a low mitotic rate for melanoma?

Patients with T1b melanomas are now defined as those for which the tumor thickness is ≤ 1.0 mm and for which there is at least 1 mitosis/mm2 or tumor ulceration.

What is high mitotic index?

An elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be elevated compared to normal growth of tissues or cellular repair of the site of an injury.

What is high mitotic rate?

The higher the mitotic count, the more likely the tumor is to have metastasized (spread). The logic is that the more cells are dividing, the more likely they will invade the blood or lymphatic vessels and thus spread around the body.

What is the AJCC staging system for melanoma?

Expert commentary: A standardized and contemporary cancer staging system that facilitates accurate risk stratification is essential to guide patient treatment.
