Mohs microscopic surgery (MMS) is still perceived as a somewhat unfamiliar and unknown treatment option to many patients with melanoma. Wide local excision (WLE) has been the standard treatment option until the recent years, with emergence of multiple literatures that have shown successful treatment of melanoma cases, presenting with high cure rate and low recurrence rate. However, variations among many physicians and practices still exist due to a lack of strict criteria and guidelines in using MMS. These variations are problematic because they can lead to financial burden for patients and inconvenience of multiple surgeries that can be avoidable1. To be able to improve the quality of patient care, a strict criteria and guidelines must …show more content…
This process is expressed in about 60% of melanoma cases, aiding more frequently in proliferation of tumor cells, especially on non-sun exposed skin, such as trunk and legs. Numerous studies have shown that BRAF mutation is present in primary and metastatic melanoma5. This mutation in BRAF proceeds to the activation of RAF/MEK pathway, which is the communication of proteins that play a role in transporting signals from a receptor on the surface to the DNA in the nucleus of the cell. Epidemiology of Cutaneous Melanoma There are three main types of skin cancer: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. CM is the rarest kind, but is also in the most dangerous form, occurring 91.2% of all melanoma. The occurrence of CM has been increasing over the past few decades, affecting not just adults but also in children and adolescents, with average age in the seventh decade6. It is ethnicity-dependent, with highest chance in Caucasian population, but other groups can also be affected7. Men usually develop melanoma on the trunk, whereas women on the extremities, but more men are affected (46,870 men and 29,510 women), according to an estimation by The Skin Cancer Foundation in 20168. People who live in areas with more intense sun exposure can also have higher risk. Besides direct UV exposure, those who have personal or family history of skin cancer or any atypical nevi are also at higher risk.
Unlike other cancers which we can develop, melanoma can often be detected on the skin which allows doctors to treat it at its early stages resulting in less complications and lower death rates to patients, again if left undetected at its early stages this can easily spread to distant areas and distant organs. Once melanoma has spread to other areas of the body which is classified as stage IV it is diagnosed as
There is insufficient evidence to determine how gene expression profiling may be used to guide clinical decisions related to the diagnosis and treatment of cutaneous melanoma. Specifically, it is not known how or whether decisions concerning treatment and surveillance are improved over the current standard of care, and it is unknown whether health outcomes are improved as a result those decisions. Further, the clinical practice guidelines from the National Comprehensive Cancer Network (NCCN) recommend against routine prognostic testing for low versus high metastatic risk outside of clinical trials. Thus, the use of DecisionDX Melanoma gene expression profile testing is considered investigational for guiding clinical decisions related to the diagnosis and treatment of any condition.
Acral Lentiginous Melanoma or ALM is a rare subtype of melanoma that occurs more often in people of color. It accounts for 2 to 3 percent of the all of the world’s cases of melanoma (Bradford). Dr. R. J. Reed in 1976 was the first to describe it as the appearance of dark lesions on the hands and feet. Radial or lentiginous was the main phase of its growth that lasts several years then it changes into a vertical or dermal invasive stage (Bradford). Several universities have released results on tests on ALM but since it is rare it was difficult for the research groups to get solid information because of small sample sizes. Nonetheless, studies by scientists such as Dr. R. J. Reed we able to determine that the survival rate for three years with the melanoma was on average at 11% (Bradford).
Although there are several types of skin cancer, the most aggressive form is melanoma. This cancer of the skin involves mass replication of the pigment producing melanocyte cells, which are located in the epidermis, below the basal layer. There are several factors involved with the onset of melanoma including, exposure to ultraviolet rays, genetic predisposition, numerous nevi (moles), immunosuppression, and environmental exposure to carcinogens.
There are three main types of skin cancer. These are malignant melanoma, basal cell carcinoma, and squamous cell carcinoma. While melanoma is the most life-threatening of the three, it is also the most
According to the Skin Cancer Foundation, one in five Americans will develop skin cancer in the course of a lifetime. Consider that 90% of nonmelanoma skin cancers are associated with high exposure to UV radiation from the sun (which means 90% of nonmelanoma skin cancers are preventable!) WebMD reports that Melanoma ( a severe type of skin cancer) often starts as a change in skin or a mole growth.
Malignant melanoma of the nail apparatus is extremely rare but there have been a few cases reported. It seems that almost half of the population that has been diagnosed with this disease has been misdiagnosed or did not receive the proper treatment to cure the disease. Since the cases are easily misdiagnosed, fatality is usually the outcome for most. Survival rate of this particular disease in recent studies has shown that humans live on average five years after being diagnosed with melanoma of the nail. The disease can affect either the upper or lower nail extremities. The scientist tested seven people, three males and four females, to see how this disease effects each of the patients.
The overall incidence of liver- dominant metastatic melanoma is low, particularly in comparison with that of other primary tumors, such as colon and breast cancer. However, ocular melanoma is the most common intraocular malignant tumor in adults.Due to its special biology, metastatic lesions most commonly develop most commonly in the
It’s almost 100% curable if spotted in the earliest stages. The ABCDE rule can be helpful in spotting Melanoma. ABCDE rule stands for Asymmetry, Border, Color, Diameter, and Evolving. It’s best to seek a doctor’s help if your unsure if a mole is normal or can be the first sign of Melanoma. The most basic Melanoma treatments would be Surgery, Immunotherapy, Targeted therapy, Chemotherapy, and Radiation therapy. Although if the Melanoma is spotted in the earliest stages a simple surgery can cure the skin cancer. The treatment can also depend on what stage of Malignant Melanoma you are currently at. Stages 0,1, and 2 mostly collide with surgery and sentinel lymph node biopsy. While stage 3 and 4 mostly depend on all the treatments which include chemotherapy and radiation therapy to hopefully help the chance of their survival rate. Melanoma has the highest ratings in Australia and New Zealand, with double the percentage affected here in North America. The reason to why it’s mostly impacted her might be how close they are to the equator which leaves them vulnerable to UV lights since the sun hits them mostly. In the United states, Melanoma mostly affects non-hispanic whites with a 26:1 ratio to African Americans out of every 100,000 people. 132,000 new cases appear yearly worldwide according to WHO. Melanoma is also the 3rd most common cancer in women and the fifth in men, worldwide. In
Melanoma, a type of skin cancer that normally starts in the melanocytes, a type of skin cell. In the past few years, doctors have noticed a spike in the number of cases of Melanoma. Many things can cause Melanoma, such as sun exposure or even laying in tanning beds. The use of tanning beds is the one of the large reasons why doctors believe this spike has occurred. Men are more venerable to skin cancer than women are, although women who tan are obviously more prone to getting this type of skin cancer. In the past few years, doctors have seen a rise in middle-aged women. Also compared to the 1970s doctor’s suspect that the way our clothes and bathing suits are designed now days could have something to do with this increase. The bathing
Although uveal melanoma is a rare malignancy, it is the most common primary intraocular tumor in adults (Kashyap, 2016) and occurs at a rate of 5.1 per million per year (Kaliki, 2016). Uveal melanoma may develop anywhere within the uveal tract, however it most commonly arises in the choroid (90%), followed by the ciliary body (6%) and then the iris (4%) (Kaliki, 2016). The at-risk population includes those with light skin, light eyes, ocular melanocytosis, nevi of the iris or choroid and the BRCA1-associated protein mutation (Kaliki, 2016). Uveal melanoma has been found to be most common in the middle-aged Caucasian population with a median age of 62 years old at presentation and with a 30% higher incidence among males relative to females
Like most diseases there are treatments and drugs used to treat the cancer. These treatments include chemotherapy, radiation, surgery, medicinal therapy used to target specific cells, and biological therapy used to help strengthen the immune system. Medicine that is used during the stages of melanoma are “Vemurafenib (Zelboraf), dabrafenib (Tafinlar) and trametinib (Mekinist) are targeted therapy drugs used to treat advanced melanoma.” (Mayo Clinic Staff 2016). More test such as biopsies are taken after targeted therapy to analyze how well the drugs are helping diminish the cancerous
Skin cancer is the most common out of all cancers. About 3.5 million cases are basal and squamous cells. Melanoma a more dangerous skin cancer had 73,000 cases in 2015.The most common types of skin cancer are basal, melanoma and squamous cell skin carcinoma. Basal a type of skin cancer that begins in the basal cells. Melanoma the most serious type of skin cancer. Squamous cell skin carcinoma a form of skin cancer that develops in the cells of the outer layer of the skin. Skin cancer begins in the cells that make up the epidermis. When the DNA that controls the cells growth is damaged, it causes an overgrowth and build up of skin cells. Eventually, this skin cell buildup forms a tumor, which results in the symptoms you see. Some causes of skin cancer are sun, solar radiation, ultraviolet tanning
Melanoma is a type of skin cancer, but what is it, and how does it form? Well, according to the Mayo Clinic, melanoma causes DNA damage to cells which begin to grow out of control and can eventually form a mass of cancerous cells (Mayoclinic.org). Elderly men are at highest risk, but melanoma is the most common cancer in young adults 25 to 29 years old (ASCO). Therefore, all ages are prone to melanoma. Melanoma not only occurs in men, it also occurs in women. The
According to the Centers for Disease Control and Prevention, the most common form of cancer in the United States is melanoma skin cancer (2014). It is crucial that melanoma needs to be detected at an early stage to improve survival rates. There are current techniques such as a dermatoscopy that can help the physician to make a diagnosis, but it remains difficult and the need of new techniques or tools is required to improve the physician’s diagnostic abilities. According to cancer statistics, the incidence of melanoma has doubles and been increasing steadily in recent decades (2011).
