What Is The Prognosis Of Metastatic Cancer To Skin
- The prognosis of Metastatic Cancer to Skin depends on many factors such as the severity of signs and symptoms, the number of organ systems affected, and the individual response to treatment
- Individuals, who respond well to treatment, have better prognosis than those who do not respond to treatment
- However, the prognosis is usually poor because skin metastasis often indicates a high-stage cancer. It can result in death
What Can We Do
Both breast cancer and melanoma survivors should be vigilant and take extra preventative and early detection measures to reduce their risk of developing a second cancer.
Lifestyle changes like quitting smoking , maintaining a healthy weight, exercising, and minimizing alcohol intake can help reduce breast cancer risk. To detect breast cancer early, women over 40 should get yearly mammograms and all women should conduct monthly breast self-exams.
Melanoma risks can be reduced by avoiding tanning beds and excessive sun exposure. If you plan to be in the sun or in reflective areas , cover up with a hat and dark, dry, tightly-woven clothing. Special UPF-rated clothing, clothing which protects against UV rays, is also available. Sunglasses that block both UVA and UVB rays will help protect the eyes and delicate skin around the eyes. For exposed skin, use a broad-spectrum sunscreen of SPF30 or above that blocks UVA/UVB. Apply sunscreen frequently and liberally and follow the products instructions. Talk to your doctor about getting a skin exam and do a skin self-exam on a regular basis. These check-ups can help you learn what is normal for your skin, what is changing, and what may need a closer look.
Remember, while cancer may be scary, knowledge is power, and by learning more about your body and your risk factors, you can take control of your health and reduce your risks.
What Is The Treatment For Cutaneous Metastasis
The underlying primary tumour needs to be treated. However, in most cases where skin metastasis has occurred, the primary cancer is widespread and may be untreatable. In this case, palliative care is given and includes keeping lesions clean and dry. Debridement can be done if lesions bleed or crust. Other therapies that may be helpful include:
- Imiquimod cream may lead to regression of metastasis in some cases of melanoma

Risk Factors For Metastatic Melanomas
You cannot get metastatic melanoma without first having melanoma, though the primary melanoma may be so small its undetectable. Major risk factors for melanomas include:
- Light skin, light-colored hair or light-colored eyes
- Skin prone to burning easily
- Multiple blistering sunburns as a child
- Family history of melanoma
- Frequent exposure to sun or ultraviolet radiation
- Certain genetic mutations
- Exposure to environmental factors, such as radiation or vinyl chloride
Other factors have been connected with increased metastasis. In a 2018 study in the Anais Brasileiros de Dermatologia and a 2019 study in the Journal of the National Cancer Institute, the following factors were associated with higher levels of metastasis:
- Male gender
- Primary tumor thickness of more than 4 mm
- Nodular melanoma, which is a specific subtype that a care team would identify
- Ulceration of the primary tumor

Abstract: Malignant melanoma of the breast is a rare disease that accounts for 35% of all melanomas. It can be expressed as a metastatic mammary gland or primary mammary melanin of the mammary gland. Primary MMB can be divided into two types: parenchymal melanoma without skin involvement and melanoma involving skin on the breast. The diagnosis of PMMB relies mainly on histopathological diagnosis. In this diagnostic approach, S100 and HMB45 have a higher specificity in the diagnosis of melanoma immunohistochemistry. At the same time, mutations in the BRAF gene have further aided the diagnosis of PMMB. After the diagnosis, the main treatment is mainly based on surgery. The main surgical methods include breast-conserving surgery and mastectomy. With advances in technology and surgical skills, the combination of patient aesthetic satisfaction and tumor safety is the goal of modern breast surgeons. This article reviews the current status of PMMB surgical treatment.

Context.âThe mammary gland can be a site of metastasis in patients with malignant melanoma, which is easily recognized microscopically if clinical information is available. Nonetheless, metastatic melanoma presenting as an isolated mammary tumor can be more challenging to diagnose because it can simulate a primary breast carcinoma clinically and morphologically.
Objective.âTo review metastatic melanoma to the breast, presenting as primary breast carcinomas clinically and morphologically.
Design.âThe authors report 20 cases of metastatic melanoma clinically presenting as breast tumors. Cases with widespread metastatic presentation were excluded.
What Is Metastatic Cancer To Skin
Basic information on Metastatic Cancer to Skin is as follows:
- Metastatic Cancer of Skin is a condition where cancers originating from various parts of the body spread to the skin. Metastasis can occur on the skin, either as a single nodule or multiple nodules. If these nodules get large in size, then they can ulcerate and bleed
- Some cancers metastasize to skin more often than other cancer types. Common cancers that metastasize to skin include:
- Melanoma
- Cancer of nasal cavities and nasal sinuses
- Cancer of larynx
- Cancers of endocrine glands
- Cancer of esophagus
- Cancers of kidney
- Stomach cancer

Skin Cancer Metastasis To The Brain
Late-stage melanoma – the most aggressive form of skin cancer – can spread through the bloodstream from its original location to the brain and other parts of the body. This occurrence is known as skin cancer metastasis, metastatic skin cancer or metastatic melanoma.
Several cancers can metastasize from their original site to the brain, the most common being lung and breast cancers, followed by melanoma. In these instances, the original cancer is referred to as the primary cancer, while the metastasis is known as the secondary cancer or tumor. Secondary brain tumors that originate from melanoma are actually masses of skin cancer cells.
Scans For Assessing Melanoma Spread
Why do I Need to Have a Scan for Melanoma?
Scans are done to assess whether the melanoma has spread . The complexity of the scans is determined by the risk of spread.
Types of Scans Used to Assess Melanoma Spread
X-ray
If there is a low risk of spread then the only scan that is required is an X-ray of the lungs. The reason for this is that the lungs are the most common organ that melanomas spread to and it is cheap, easy and accurate to exclude spread with an X-ray of the chest.
CT Scan
If the melanoma has penetrated more deeply and thus has a higher risk of spread to the lymph glands and internal organs, then a CT scan of the chest, abdomen and pelvis is advised as a screening method.
MRI Scan
If metastases to the brain are suspected then an MRI scan is the most accurate way of assessing this area. MRI is also used as a means to increase the accuracy of diagnosis of suspicious areas seen within the liver on ultrasound or CT scan.
Ultrasound Scan
If an enlarged lymph gland is detected on clinical examination, then an ultrasound scan of the lymph nodes is requested. An ultrasound scan gives the most accurate assessment of lymph node metastases.
PET-CT Scan
It is important to note that no type of scan can detect microscopic melanoma disease.

Metastatic Melanoma Of The Breast
There were three patients in this group. As previously published , in case 10 with stage III mid-back CMM, wide local excision and bilateral axillary lymph node dissection was performed. During the follow-up period, skin IMs were diagnosed by biopsy over the right breast. Extended mastectomy and skin graft reconstruction were done to this patient. Pathological examination of the breast showed diffuse in-transit metastasis and intra-mammary lymph nodes metastases together with skin IMs. Although the patient received adjuvant radiation therapy, IMs occured both on the previously grafted/irradiated area and healthy skin. Wide local excision and skin graft reconstruction were performed again. The patient died of recurrent disease on both ipsilateral and contralateral hemithorax and systemic dissemination 31 months after last surgery.
Figure 1.
A 35-year-old female with CMM of the mid-back on whom WLE, skin grafting and bilateral axillary lymph node dissection were performed. In-transit metastases on skin and breast parenchyma developed under IFN treatment. Although extended mastectomy with skin graft, and radiation therapy were performed, local recurrences occurred. Re-excision and skin grafting were performed . In the late period of illness, in-transit metastases invaded both the previously treated area and opposite breast.
Sentinel Lymph Node Biopsy For Melanoma
Why do I need a Sentinel Lymph Node Biopsy?
The most important advancement for the screening of melanoma metastases has been the development of the sentinel lymph node biopsy. This technique allows one to accurately identify the single lymph gland within a lymph node region that has the greatest likelihood of harbouring a metastasis . This test is only done if no enlarged lymph nodes are evident on examination and was developed to be able to identify lymph glands with microscopic spread that would not be detected on routine scans. With practice, it is possible to accurately identify the sentinel lymph gland 99% of the time. If the sentinel gland contains no melanoma, then one can be 99% sure that none of the other glands within that region have melanoma metastases. This is very important information because people who have no spread to their lymph glands have a goodprognosis, while those in whom there has been even a microscopic amount of spread, the prognosis is worse. Prior to the development of the sentinel lymph node biopsy technique, it was standard practice to remove all the lymph glands from the region draining the melanoma. This meant that about 80% of patients had a large and unnecessary operation.

How Is Electrochemotherapy Given
Many people need only a single treatment of electrochemotherapy, although it can be repeated in the same area or used to treat a different area.
Treatment is usually carried out as an outpatient or day case, though some people may need to stay in hospital overnight. This depends on how much treatment is needed and your general health.
It can be given under general anaesthetic or sometimes local anaesthetic, depending on the size of the area or how many areas need to be treated. You may be given pain relief beforehand.
The chemotherapy is usually given into a vein . It can also be given by injection directly into the area of cancer being treated .
Bleomycin is the chemotherapy drug most commonly used. Cisplatin, another chemotherapy drug, may also be used.
A short time after the chemotherapy drug is given, electrical impulses are given directly to the area using an electrode with the help of a specially designed needle probe. The electrode may be applied a number of times to make sure the whole area is treated. The procedure usually takes about 30 minutes depending on the size of the area.
Afterwards, the area will often be covered with a dressing that may need changing regularly. The treated areas will usually scab over. Often the areas look worse before any improvement is seen.
The Spread Of Melanoma Metastasis
If you or a family member or friend have recently been diagnosed with melanoma, you may be wondering, just where and why can melanoma spread?
With surgery, melanoma confined to the skin has a 5-year survival rate in 98% of cases. Unfortunately, if the lesion recurs , gets thicker, or spreads from the skin to the lymph nodes or distant organs, it becomes much more dangerous. This occurs in stage III and IV melanoma and is called melanoma metastasis.

Common Places For Melanoma To Spread
Melanoma can spread from the original site on your skin and form a tumor in any organ or body tissue, but its most likely to metastasize to the lymph nodes, liver, brain, lungs, and less commonly, the bones. Melanoma really likes the brain and the liver, says Lisa Zaba, M.D., dermatologic oncologist at Stanford Medical Center in San Jose, CA. If you notice any of the following red flags, it might mean your melanoma has spread and warrants a call to your doctor right away.
What Is Electrochemotherapy
Electrochemotherapy combines a low dose of a chemotherapy drug with electrical impulses. Its given directly to the area being treated to relieve symptoms of skin metastases.
Studies have shown that electrochemotherapy can:
- help stop bleeding, broken skin and pain
- reduce the size of skin metastases
Using electrical impulses allows the chemotherapy to work in the treated areas only, with little or no effect in other areas. Electrochemotherapy wont treat any other areas of secondary breast cancer inside the body.

Spread Risk Of Melanoma
Does the Depth of Melanoma Increase the Risk of Spreading?
The risk that a melanoma has spread is most strongly related to the depth that the melanoma has managed to penetrate into the dermis of the skin. The depth of penetration is measured in millimetres and is called the Breslow depth. All melanomas start in the epidermis of the skin and while confined to this layer there is no risk of spread. Once a melanoma has penetrated from the epidermis into the dermis of the skin it then comes into contact with capillaries and lymphatic channels. The deeper a melanoma has penetrated into the skin, the more capillaries and lymphatic channels it has come into contact with. There is thus a higher risk of invasion into these structures with a resultant greater risk of spread to lymph glands and organs.
Other major features of a primary melanoma that determine the risk of spread are whether it has formed a sore and the number of actively dividing cells seen per high power field under the microscope.
Where do Melanomas Spread to?
If a melanoma metastasises the first site of spread in 90% of cases is to the regional lymph nodes. If the primary melanoma was on the leg, spread to lymph glands in the groin is most likely, while spread to glands in the arm pit is most likely from a melanoma on the arm. The minority of melanomas will spread only via the blood stream and completely bypass the lymph glands.

Symptoms Of Metastatic Melanomas
Melanoma usually is found in early stages, before its become metastatic. If you notice any abnormal moles or discolorations on your skin, dont hesitate to reach out to your doctor. This is especially important for those with many risk factors. Melanoma is more treatable at early stages, so early identification may prevent metastatic melanoma from developing.
Though a primary tumor is typically found, its possible that metastatic melanoma is detected elsewhere in the body and causes symptoms without any signs of a primary tumor.
Metastatic melanoma symptoms and signs may include:
- Fatigue
