RTN2: This phase III trial is comparing surgery alone and in combination with radiation therapy for the treatment of primary melanoma that has histoglogical features of neurotropismA Randomised Trial of Post-operative Radiation Therapy Following Wide Excision of Neurotropic Melanoma of the Head and Neck (Other IDs: TROG 08.09, 2009/039, ANZMTG 01.09)

Clinical summary

Summary

Melanoma is the third most common cancer in Australia. Approx 1000 Australians die of the disease each year. Neurotropism, defined as invasion by melanoma of peripheral neural tissue, is uncommon but it is this feature which is linked with a high risk of the cancer coming back in the same area. The primary aim of this trial is to determine if there is a difference in the rate of relapse between 2 randomised groups of patients treated after surgery with either radiation therapy or initial observation

Conditions

This trial is treating patients with Melanoma.
