Your melanoma is deeper than 4mm stage 2C and you have not had a sentinel lymph node biopsy. Clinical staging – The lymph node groups that relate to the location of the melanoma are carefully examined to for any evidence of spread usually seen by enlarged lymph nodes. The American National Comprehensive Cancer Network NCCN recommends CT or CT-PET scans 312 monthly for patients with asymptomatic stage IIBIV melanoma 13.

To review recent evidence on the role of PETCT in melanoma staging as well as its potential for future developments. In the latest years new radiopharmaceuticals have been proposed and the use of hybrid PETceCT has emerged. The European Society of Medical Oncology recommends only physical examination every three months 14.

Various imaging tests can be used with the aim of detecting metastatic spread of disease following a primary diagnosis of melanoma primary staging or on clinical suspicion of disease recurrence re-staging. The stage of a cancer describes how much cancer is in the body. Melanoma is staged according to the American Joint Committee on Cancer AJCC clinical and pathologic criteria 17.

For example some melanomas can spread so quickly that they reach the lymph nodes lungs brain or other areas while the original skin melanoma is still very small. In our institution whole-body integrated PET-CT scanning with FDG has become the standard diagnostic tool for staging patients with high-risk malignant melanoma that is Breslow thickness greater than 4 mm or known metastases. You have stage 3 or 4 melanoma.

153 Offer CT staging to people with stage IIC melanoma who have not had sentinel lymph node biopsy and to people with stage III or suspected stage IV melanoma. PETCT plays an important role in the staging workup of patients affected by melanoma. 168 of the patients with stage IIC melanoma received a PETCT for primary staging.

Thus melanoma may be primary or metastatic and the primary form may arise from the skin or much more infrequently. MRI scanning may be helpful in clarifying otherwise indeterminate liver lesions. Staging of melanoma with whole body MRI was been reported to have higher diagnostic accuracy than CT scanning in study of test accuracy and comparable to PET or PETCT in another study of test accuracy but this is unlikely to be widely utilised.

This process is called staging. For baseline staging SLN scintigraphy and biopsy are routinely performed in all patients with a malignant melanoma. PET CT Scans for the Staging of Malignant Melanoma Dermatology Advisor Contributing Writer The avoidance of surgery by increasing the stage.

Sometimes these tumors are found with imaging tests such as CT scans or other exams even before the melanoma on the skin is discovered. You are most likely to have it if. You have a CT scan to find out if the melanoma has spread to another area of your body.

Clinical staging is based on findings from the excisional biopsy of the primary lesion T and on findings from the clinical and radiologic assessments for regional lymph nodes N and distant metastases M. A total of 22645 patients with malignant melanoma were seen in these clinics in 2018. New radiopharmaceuticals and hybrid PETceCT could improve the potential of this diagnostic tool in this field.
