The 4 Stages of Melanoma: The Deadliest Form of Skin Cancer – Mayo Clinic

Cancerstaging is how doctors describe the extent of cancer in your body. Staging is defined by the characteristics of the original melanomatumor and if/how far it has spread in your body.

Melanoma is divided into stages using five Roman numerals and up to four letters that indicate a higher risk within each stage. The stage is determined mostly by specific details about the tumor and its growth that are tallied in a system called TNM. Read more about the TNM system.

Your stage is important because cancer treatment options and prognoses are determined by stage.

What Happens At Follow

Follow-up after a melanoma diagnosis is required to:

  • detect recurrence early
  • diagnose a new primary melanoma at the first possible opportunity. A second invasive melanoma occurs in 510% of melanoma patients and a new melanoma in situ is diagnosed in more than 20% of melanoma patients.

The Australian and New Zealand Guidelines for the Management of Melanoma make the following recommendations for follow-up for patients with invasive melanoma.

  • Self-skin examination
  • Routine skin checks by patient’s preferred health professional
  • Follow-up intervals are preferably six-monthly for five years for patients with stage 1 disease, three-monthly or four-monthly for five years for patients with stage 2 or 3 disease, and yearly after that for all patients.
  • Individual patients needs should be considered before an appropriate follow-up is offered
  • Provide education and support to help the patient adjust to their illness

The follow-up appointments may be undertaken by the patient’s general practitioner and specialist.

Follow-up appointments may include:

  • Check of the scar where the primary melanoma was removed -visual inspection and palpation
  • Feel for the regional lymph nodes
  • General skin examination
  • Full physical examination
  • In those with many melanocytic naevi or atypical melanocytic naevi, baseline whole-body imaging and sequential macro and dermoscopy images of melanocytic lesions of concern .

In those with more advanced primary disease, follow-up may include:

The 5 Stages Of Nail Melanoma

Nail melanoma is a life-threatening skin cancer that grows to affect the nails, usually the big toe and thumb. This disease can prove to be very deadly, however treatments are readily available if diagnosed early.

This disease is often referred to as, Malignant Melanoma of Nail Unit or Nail Unit Melanoma.

  • The pigment producing cells of the body, called Melanocytes, is where the Melanoma cancer develops. The Melanocytes are responsible for giving our skin its color.
  • The development of Melanoma cancer, usually begins from a finger or toenail, however thats not always the case.
  • It has the tendency to affect the areas around such as the sides of nail or the nail bed. In fact, it may also spread to other parts of the body, if not treated on time.
  • The big toe or thumb is usually the first to get affected, however it may vary according to each case.
  • The Nail Unit Melanoma is divided into 3 main types:
  • Subungual Melanoma
    • Nail Melanoma is most common in light/fair skinned people as opposed to dark skinned people.

    There are 5 stages of Nail Melanoma, stated as follows

    Stage 1: aka Stage O Melanoma

    This stage is also referred to as Melanoma in situ, meaning site of origination of Melanoma. At this point, a tumor has formed on the outermost layer of the skin, epidermis.

    Stage 2: aka Stage I Melanoma

    This stage is further categorized into two:

    Stage IA: At this stage, the tumor is less than a mm deep and has no signs of an ulcer.

    Stage 3: aka Stage II Melanoma

    Clinical Staging And Pathologic Staging

    To add to the complexity of staging, the cancer also may have a clinical stage and a pathologic stage.

    Clinical staging takes place before surgery, based on blood tests, physical exams or imaging tests such as X-rays, a computed tomography scan, magnetic resonance imaging or positron emission tomography scans.

    What doctors discover during surgery may provide more detailed information about the cancers size and spread. Often, some tissue from the surgery will be examined afterward to provide more clues. This process is known as pathologic staging, or surgical staging.

    If surgery isnt possible, doctors will use the clinical stage when determining a treatment plan.

    How Do Doctors Diagnose The Stage Of Melanoma

    Doctors will recommend a number of testing methods to determine the existence and spread of the melanoma. Examples of these methods include:

    • Physical exam. Melanoma can grow anywhere on the body. This is why doctors often recommend thorough skin checks, including on the scalp and in between the toes. A doctor may also ask about any recent changes in the skin or in existing moles.
    • CT scan. Also called a CAT scan, a CT scan can create images of the body to identify potential signs of tumor and tumor spread.
    • Magnetic resonance imaging scan. This scan uses magnetic energy and radio waves to generate images. A doctor can administer a radioactive material known as gadolinium that highlights cancer cells.
    • Positron emission tomography scan. This is another imaging study type thattests for where the body is using glucose for energy. Because tumors consume glucose more significantly, they will often show up as bright spots on the imaging.
    • Blood testing. People with melanoma may have higher-than-normal levels of the enzyme lactate dehydrogenase .
    • Biopsy. A doctor may take a sample of a potentially cancerous lesion as well as nearby lymph nodes.

    Doctors will consider the results of each of these tests when determining cancer stage.

    Changing The Standard Of Care For Stage Iii Melanoma Surgery

    For years, surgery for patients with stage III melanomamelanoma that has spread to the lymph nodesinvolved removing those lymph nodes along with the primary tumor. Known as completion lymph node dissection , the surgery was meant to ensure that no cancer remained after surgery.

    More recently, however, cancer surgeons have discovered that CLND has the potential to cause more problems than it solves. In most cases, patients do better on immunotherapy alone than they do when their surgery involves removal of the lymph nodes, due to potential complications from lymph node surgery.

    In a paper published in February in the Annals of Surgical Oncology, University of Colorado Cancer Center members Martin McCarter, MD, Camille Stewart, MD, Karl Lewis, MD, William Robinson, MD, Ana Gleisner, MD, Ph.D., and Rene Gonzalez, MDalong with CU School of Medicine resident Robert Torphy, MD, Ph.D.reviewed their patient data to determine if immunotherapy alone resulted in better outcomes than CLND.

    Better outcomes with immunotherapy

    For the study, Torphy, working with McCarter and the other researchers, looked at data on 90 patients who underwent sentinel lymph node biopsy only for stage III melanoma but did not undergo CLND. Of those patients, 56 received immunotherapy and 34 did not. Those who received immunotherapy had better rates of distant metastasis-free survival, meaning their cancer was less likely to come back.

    Treatments For Stage I Melanoma

    Your doctor will most likely treat stage 1 melanoma with surgery called wide excision, which cuts out the melanoma along with a margin of healthy surrounding skin. The amount of healthy skin removed is determined by the location and the thickness of the melanoma being treated.

    While wide excision surgery is often the only treatment necessary, in some cases a doctor may also choose to check for cancer in nearby lymph nodes by performing a sentinel lymph node biopsy. If cancer cells are found in the lymph nodes, further treatment will become necessary, such as a lymph node dissection , chemotherapy, immunotherapy, or targeted therapies.

    Stage I And Stage Ii Melanoma

    The Five Stages of Prostate Cancer | Prostate Cancer Staging Guide

    Stage I and stage II melanoma describe invasive cancer that has grown below the epidermis to the next layer of skin, the dermis. It has not reached the lymph nodes.

    Two major factors help determine the seriousness of stage I melanoma and stage II melanoma: Breslow depth and ulceration.

    Breslow depth is a measurement that doctors use to describe the depth of an invasive melanoma in millimeters. It measures how far melanoma cells have reached below the surface of the skin. The thinner the melanoma, the better the chances for a cure.

    Ulceration means that there is broken skin covering the melanoma. This breakage can be so small that it can only be seen under a microscope. Ulceration is an important factor in staging. A melanoma with ulceration may require more aggressive treatment than a melanoma of the same size without ulceration.

    Melanoma is considered stage 1A when:

    • the tumor is less than or equal to 1 millimeter thick in Breslow depth

    Melanoma is considered stage IB when:

    • the tumor is 1.1 to 2 millimeters thick in Breslow depth without ulceration

    Melanoma is considered stage IIA when:

    • the tumor is 1.1 to 2 millimeters thick in Breslow depth with ulceration
    • the tumor is 2.1 to 4 millimeters thick in Breslow depth without ulceration

    Melanoma is considered stage IIB when:

    • the tumor is 2.1 to 4 millimeters thick in Breslow depth with ulceration
    • the tumor is more than 4 millimeters in Breslow depth without ulceration

    Melanoma is considered stage IIC when:

    How Is Melanoma Treated

    Your melanoma treatment will depend on the stage of the melanoma and your general health.

    Surgery is usually the main treatment for melanoma. The procedure involves cutting out the cancer and some of the normal skin surrounding it. The amount of healthy skin removed will depend on the size and location of the skin cancer. Typically, surgical excision of melanoma can be performed under local anesthesia in the dermatologist’s office. More advanced cases may require other types of treatment in addition to or instead of surgery.

    Treatments for melanoma:

    • Melanoma Surgery: In the early stages, surgery has a high probability of being able to cure your melanoma. Usually performed in an office, a dermatologist numbs the skin with a local anesthetic and removes the melanoma and margins .
    • Lymphadenectomy: In cases where melanoma has spread, removal of the lymph nodes near the primary diagnosis site may be required. This can prevent the spread to other areas of your body.
    • Metastasectomy: Metastasectomy is used to remove small melanoma bits from organs.
    • Targeted cancer therapy: In this treatment option, drugs are used to attack specific cancer cells. This targeted approach goes after cancer cells, leaving healthy cells untouched.
    • Radiation Therapy: Radiation therapy includes treatments with high-energy rays to attack cancer cells and shrink tumors.
    • Immunotherapy: immunotherapy stimulates your own immune system to help fight the cancer.

    What Are The Signs Of Melanoma

    Knowing how to spot melanoma is important because early melanomas are highly treatable. Melanoma can appear as moles, scaly patches, open sores or raised bumps.

    Use the American Academy of Dermatology’s “ABCDE” memory device to learn the warning signs that a spot on your skin may be melanoma:

    • Asymmetry: One half does not match the other half.
    • Border: The edges are not smooth.
    • Color: The color is mottled and uneven, with shades of brown, black, gray, red or white.
    • Diameter: The spot is greater than the tip of a pencil eraser .
    • Evolving: The spot is new or changing in size, shape or color.

    Some melanomas don’t fit the ABCDE rule, so tell your doctor about any sores that won’t go away, unusual bumps or rashes or changes in your skin or in any existing moles.

    Another tool to recognize melanoma is the ugly duckling sign. If one of your moles looks different from the others, its the ugly duckling and should be seen by a dermatologist.

    particularly affected by these statistics. According to the Cancer Council Australia , non-melanoma skin cancer is more common in men than in women, this may be due to the fact that men may wear less when going out in the sun and will take risks more, possibly by not wearing protective clothing and sunscreen. As well as this fact it is also conveyed that the age group most affected by melanoma is ranged between 15-44 years old, this may be due to people from this age group especially teenagers

    The Effects Of Melanoma On The Integumentary System Essay

    explain the effects of melanoma on the integumentary system.SkinThe skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the

    Relevance Of Tnm Criteria

    • Thick or ulcerated melanomas and actively dividing or disordered melanomas have a greater potential to invade and spread.
    • Thin tumors and non-ulcerated tumors are less likely to spread and have better cure and recurrence rates.
    • Intermediate tumors lie in between. Once the melanoma has spread to nodes and metastasized to distant sites, it is harder to treat.

    Can Changing My Diet Help Prevent Melanoma

    The American Cancer Society advocates eating a plant-based diet over an animal-based diet as part of a healthy plan to avoid all cancers. Growing evidence suggests that plants pack a powerful punch in any fight against cancer because they’re nutritious, cholesterol-free and fiber-rich.

    Theres no doubt that a healthy diet can protect your immune system. Having a strong immune system is important to help your body fight disease. Some research has shown that a Mediterranean diet is a healthy choice that may help prevent the development of cancer. Talk to your healthcare provider about the role food plays in lowering your cancer risks.

    Some skin and immune-system healthy foods to consider include:

    • Daily tea drinking: The polyphenols in tea help strengthen your immune system. Green tea contains more polyphenols than black tea.
    • High vegetable consumption: Eating carrots, cruciferous and leafy vegetables is linked to the prevention of cutaneous melanoma.
    • Weekly fish intake: Study participants who ate fish weekly seemed to avoid developing the disease when compared to those who did not eat fish weekly.

    Stages Of Melanoma Skin Cancer

    What are the Stages of Cancer? | Best Cancer Treatment Hospital in Hyderabad

    Staging describes or classifies a cancer based on how much cancer there is in the body and where it is when first diagnosed. This is often called the extent of cancer. Information from tests is used to find out the size of the tumour, which parts of the skin have cancer, whether the cancer has spread from where it first started and where the cancer has spread. Your healthcare team uses the stage to plan treatment and estimate the outcome .

    The most common staging system for melanoma skin cancer is the TNM system. For melanoma skin cancer there are 5 stages stage 0 followed by stages 1 to 4. Often the stages 1 to 4 are written as the Roman numerals I, II, III and IV. Generally, the higher the stage number, the more the cancer has spread. Talk to your doctor if you have questions about staging.

    When describing the stage, doctors often use the words early stage, locoregional or metastatic.

    Early stage means that the cancer is only in where it started and has not spread to other parts of the body. It includes stage 0, stage 1A, stage 1B, stage 2A, stage 2B and stage 2C melanoma skin cancers.

    Locoregional means the cancer has spread to nearby lymph nodes, or it has spread to nearby areas of skin or lymph vessels. It includes stage 3 melanoma skin cancer.

    Metastatic means that the cancer is in a part of the body farther from where it started. It includes stage 4 melanoma skin cancer.

    Study Design And Outcome

    This study used a retrospective cohort study design. The study population was the primary site of melanoma from 2009 to 2017 in the TCR. The index date was admitted with the first diagnosis date of melanoma. The comparison group was defined as never diagnosis of melanoma from 2000 to 2018 . Due to the consistent index date between the melanoma group and the non-melanoma group, a 1:10 age and sex matching was conducted. The outcome variable was all-cause mortality. Both groups were followed up until the onset of death, or December 31, 2018, whichever occurred first.
