PRIMARY OBJECTIVE:
I. To determine if regional nodal radiation therapy prolongs the time to regional recurrence.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I: Patients receive adjuvant immunotherapy and nodal radiation therapy (30 Gy in 5 treatments over 2-2.5 weeks).
GROUP II: Patients receive adjuvant immunotherapy alone.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

You may be eligible if
Must be planned for post-operative immunotherapy
No evidence of distant metastasis as determined by clinical examination and any form of imaging
No evidence of clinically involved lymph nodes prior to SLNB
Pathologically confirmed sentinel lymph node positive melanoma with high risk features (extracapsular extension \[ECE\] or 0.5 mm+ nodal tumor implant or 2+ involved nodes or lymphovascular invasion of the primary tumor)
Has provided written informed consent for participation in this trial
Eastern Cooperative Oncology Group (ECOG) performance status of 3 or less
Life expectancy greater than 6 months
Patients capable of childbearing are using adequate contraception
Available for follow-up
You may not be if
Complete lymph node dissection (CLND) of the nodal basin containing the positive SLN
Distant metastasis
Previous radiation therapy (RT) to the nodal area planned for RT such that the prior RT field would be included in the current treatment field. In other words, treatment on this trial would require re-irradiation of tissues

Adults unable to consent, individuals who are not yet adults, pregnant women and prisoners will be excluded from this study
