Vaginal melanoma accounts 5.5% of all vaginal cancers and only 1% of all melanomas diagnosed in women. [2] Vaginal melanomas are frequently diagnosed in advanced stages of the disease. The prognosis is poor and the most important risk factor is the presence of lymph node metastases. [2] [3]
Neither sentinel lymph node biopsy nor other diagnostic tests should be performed to evaluate early, thin melanoma, including melanoma in situ, T1a melanoma or T1b melanoma ≤ 0.5mm. [114] People with these conditions are unlikely to have the cancer spread to their lymph nodes or anywhere else and have a 5-year survival rate of 97%. [ 114 ]
N1: regional lymph node metastasis present; at some sites, tumor spread to closest or small number of regional lymph nodes; N2: tumor spread to an extent between N1 and N3 (N2 is not used at all sites) N3: tumor spread to more distant or numerous regional lymph nodes (N3 is not used at all sites) M: presence of distant metastasis. M0: no ...
The concept of the sentinel lymph node is important because of the advent of the sentinel lymph node biopsy technique, also known as a sentinel node procedure.This technique is used in the staging of certain types of cancer to see if they have spread to any lymph nodes, since lymph node metastasis is one of the most important prognostic signs.
In the event that the melanoma spreads to other sites such as the lymph nodes, another biopsy called the Sentinel lymph node biopsy may provide more information in terms of outcomes. [21] More extensive melanomas may require wider excision (margins of 0.5 cm or more), digital amputation, lymphangiogram with lymph node dissection, or ...
[67]: 29, 31 Even though it is much less common, malignant melanoma is responsible for 75% of all skin cancer-related deaths. [68] The survival rate for people with melanoma depends upon when they start treatment. The cure rate is very high when melanoma is detected in early stages, when it can easily be removed surgically.
A large study validated the importance of tumor depth (but not Breslow's original description) as one of the three most important prognostic factors in melanoma (the others being T stage and ulceration). [4] Breslow's depth also accurately predicted the risk for lymph node metastasis, with deeper tumors being more likely to involve the nodes. [5]
