What is mucosal melanoma?
Mucosal melanoma (MM) is a rare melanoma subtype that originates from melanocytes within sun-protected mucous membranes. Compared with cutaneous melanoma (CM), MM has worse prognosis and lacks effective treatment options.
How do you stage mucosal melanoma?
The staging and survival rates vary based on the location of the mucosal melanoma….This clinical staging system is as follows:
- Stage 1: The disease remains localized.
- Stage 2: Nodes in the region or area around the disease become involved.
- Stage 3: The disease becomes metastatic and involves distant areas and organs.
How effective is Immunotherapy for mucosal melanoma?
In patients with mucosal melanoma treated with pembrolizumab, the objective response rate (ORR) was 19% (compared to 33% in patients with a cutaneous primary). In responders, the median durability of response was similar between mucosal and cutaneous primaries with 75% and 72% having an ongoing response, respectively.
Is there a difference between melanoma and malignant melanoma?
Melanoma is a cancer that begins in the melanocytes. Other names for this cancer include malignant melanoma and cutaneous melanoma. Most melanoma cells still make melanin, so melanoma tumors are usually brown or black. But some melanomas do not make melanin and can appear pink, tan, or even white.
What is the difference between a carcinoma and a melanoma?
That compound both protects the skin from sunlight and determines its color. The other big difference between the two types of cancer is the survival rate. Melanomas are generally much more dangerous than carcinomas. Early detection helps with treatment in both cases and can be a key to dealing with the problem.
Who gets mucosal melanoma?
Mucosal melanoma hasn’t been linked to any specific causes. Generally, older people are diagnosed, with the median age being 70. While the rate of skin melanoma cases has risen in the past 20 years, the rate of mucosal melanoma has always been fairly similar over time.
Has anyone survived mucosal melanoma?
A retrospective study by Bakkal et al of 10 patients with mucosal melanoma of the head and neck region found 3-year disease-free and overall survival rates to be 11.7% and 35%, respectively, while the 5-year rates were 11.7% and 23.3% respectively.
Can you survive mucosal melanoma?
Mucosal melanoma is a disease with a very poor prognosis and most patients will develop incurable metastatic disease, irrespective of surgical excision. 5-year survival rates may be as low as 14%, compared with 90% for cutaneous melanoma [4,5] when all cases, regardless of stage are combined.
Is mucosal melanoma treatable?
The only curative treatment for mucosal melanoma is surgical resection. Complete surgical resection of mucosal melanoma with negative pathological margins is associated with a better prognosis [20,34] but there is no evidence that radical resection improves survival [35–38].
Which is worse melanoma or carcinoma?
While it is less common than basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage. Learn more about melanoma types, risk factors, causes, warning signs and treatment.
Mucosal melanoma develops in the mucous membrane that lines the nose, mouth, esophagus, anus, urinary tract and vagina. Mucosal melanomas are especially difficult to detect because they can easily be mistaken for other far more common conditions. Melanoma in the eye.
What is acral-lentiginous melanoma?
Acral-lentiginous melanoma is a rare form of melanoma that can occur under a fingernail or toenail. It can also be found on the palms of the hands or the soles of the feet. It’s more common in black people and in other people with darker skin pigment.
What are melanomas of the feet?
Melanomas can also occur in areas that don’t receive much sun exposure, such as the soles of your feet, palms of your hands and fingernail beds. These hidden melanomas are more common in people with darker skin.
What are melanomas and how do they develop?
Melanomas can also develop in areas of your body that have little or no exposure to the sun, such as the spaces between your toes and on your palms, soles, scalp or genitals. These are sometimes referred to as hidden melanomas because they occur in places most people wouldn’t think to check.
