    Study Notes

    Skin Cancer Treatment

    • A collaborative team of healthcare professionals (HCPs) is crucial for early detection and prompt intervention in skin cancer patients.
    • Nurses play a vital role in guiding patients towards informed treatment decisions based on their individual needs.
    • Treatment options for non-melanoma skin cancer include:
      • Surgery
      • Curettage and electrodessication
      • Cryotherapy
      • Radiotherapy
    • These modalities boast a cure rate exceeding 90%.
    • Other treatment methods include:
      • Chemotherapy
      • Immunotherapy
      • Radiation therapy
    • Biological therapies utilizing interleukin-2 and interferon, alongside therapeutic vaccines containing melanoma antigens, are occasionally employed.
    • Regular post-treatment examinations are imperative to monitor for potential recurrence.

    Malignant Melanoma Management

    • Early identification, diagnosis, and tumor staging are paramount in managing malignant melanoma.
    • Surgical excision is the primary treatment for treatable tumors.
    • Chemotherapy, immunotherapy, and radiation therapy are also utilized in treating malignant melanoma.

    Malignant Melanoma Location

    • Malignant melanoma frequently develops on the trunk of men and lower extremities of women.

    Melanoma Development

    • Only 20-30% of melanoma tumors originate from pre-existing moles (nevi).
    • The remaining melanoma cases can arise anywhere on the body.

    ABCDE Rule for Suspicious Lesions

    • Asymmetry: One half of the mole does not match the other half.
    • Border irregularity: Edges are ragged or notched.
    • Color variation: Includes shades of brown, black, red, white, and/or blue.
    • Diameter: Greater than 6 mm (size of a pencil eraser) or dark in color.
    • Evolving: Changes in shape, size, color, or new symptoms like crusting or bleeding may indicate melanoma.

    Melanoma Diagnosis & Tests

    • Melanoma is a serious skin cancer
    • If melanoma is suspected, the doctor will perform a physical exam, including palpation of lymph nodes, the liver, and the spleen
    • Palpation is a key step to evaluate for metastasis, meaning cancer spreading to other parts of the body.
    • Biopsy of a suspicious lesion is crucial for diagnosis.
    • Malignant melanoma can metastasize (spread) to any organ or tissue.
    • Different tests are used to figure out if the cancer has spread.
    • These tests include liver function tests, CT of the liver, CBC, serum blood chemistry profile, chest x-ray, bone scan, and CT or MRI of the brain.

    Microstaging

    • Microstaging assesses the depth of melanoma invasion
    • Two methods are used, the:
      • Clark System: This system measures the vertical growth from the epidermis to the subcutaneous tissue, but is prone to variations in skin thickness
      • Breslow System: This system adjusts the Clark system by measuring the vertical thickness from the epidermis granular layer to the tumor's deepest invasion, offering a more precise measure
    • Survival rates for melanoma decrease as the thickness of the tumor increases

    Malignant Melanoma Treatment

    • Surgical excision is the preferred treatment for malignant melanoma.
    • A wide excision is performed that includes the full thickness of the skin and subcutaneous tissue.
    • For thin melanomas (smaller than 0.76 mm) margins of 0.5 to 1.0 cm of normal skin are excised around the tumor.
    • Thick tumors require a 1- to 3-cm margin excision because they are at risk for local recurrence or satellite lesions.
    • Regional lymph nodes are the most common sites for metastasis of malignant melanoma.
    • Standard surgical treatment for clinically suspicious lymph node involvement includes excision of the primary lesions as well as surgical dissection of the involved lymph nodes.
    • Elective lymph node dissection (ELND) in the treatment of localized malignant melanoma remains controversial.
    • Studies have not indicated any survival benefit for patients treated with ELND.
    • Surgery is indicated for palliative management of isolated metastasis.
    • Removal of metastatic tumors in the brain, liver, lung, GI tract, or subcutaneous tissue may relieve symptoms and prolong life.

    • Instruct patients to avoid grapefruit and grapefruit juice while taking encorafenib
    • Instruct patients to wear sunscreen and avoid sun exposure while taking vemurafenib
    • Inform patients of the increased risk of new skin malignancies and to notify the HCP immediately of suspicious lesions
    • Instruct patients to immediately notify the HCP if they develop symptoms of bleeding, liver dysfunction, changes in heart rhythm, eye pain or other visual changes, fever, or thromboembolism
    • Instruct patients taking vemurafenib to immediately stop the medication and notify the HCP if they experience an allergic reaction or severe skin reaction

    Interferons

    • Examples: interferon alfa-2b (Intron A), peginterferon alfa-2b (PegIntron, Sylatron)
    • Bind to receptors to inhibit cell growth
    • Monitor cardiovascular status, for symptoms of pancreatitis, signs of neuropsychiatric disorders, and symptoms of colitis
    • Instruct patients to immediately notify the HCP if they experience signs of infection, lower back or side pain, painful or difficult urination, signs of bleeding, suicidal thoughts or attempts, new or worsening anxiety, depression, agitation, or aggressive or violent behavior

    Interleukins

    • Example: aldesleukin (Proleukin)
    • Stimulate T cells, B cells, and NK cells to attack cancer cells
    • Monitor CBC with differential, platelet count, electrolytes, and kidney, liver, and thyroid function
