Almost all patients survive stage Ia malignant melanoma, and the suvivorship for stage I overall is more than 90%.
Survival drops in stage IIa to about 65% at five years and is worse yet for stage IIb at slightly over 50%.
Though radiation therapy has a minimal role in the primary treatment of malignant melanoma, for patients who have metastatic disease, radiation may be helpful.
Some patients, such as those with IIb or stage III melanoma, are at high risk for the development of recurrence after treatment.
The five year survival rate for stage 4 metastatic melanoma is around 10%.
For stage IV patients, or those that are treated and then develop recurrence at distant sites, chemotherapy or immunotherapy is planned.
Melanoma is not cured unless it is diagnosed at a stage when it can be isolated and removed surgically.
Adjuvant therapy (auxiliary drug treatment used to make possibility of relapse less for those at high risk) is also considered.
Malignant melanoma
The patients attitude, and what stage the cancer was found in.
These stages are subdivided on the basis of penetration. Stage Ia is 0.75 mm or less (1 mm = 0.04 in), and Stage Ib is 0.75-1.5 mm penetration. Stage IIa is 1.5-4.0 mm and Stage IIb is over 4.0 mm or into the subcutaneous fat.
Modest progress has been made in the treatment of metastatic melanoma over the past decade. With the advent of high dose interleukin-2 (IL-2), it may be possible for a small number of patients to be cured of their disease Despite this, the average median survival in patients treated for metastatic disease may be as short as nine months
No form of melanoma is believed to be related to asbestos.
