Surgery after immunotherapy effective in advanced melanoma

The analysis stratified patients into the following three categories based on radiological response to immunotherapy:

• Overall response to checkpoint blockade and the index lesion was either smaller since initiation of therapy or stabilized (12; 5.1%). Half of this group had a pathological complete response.
• Isolated site of progressive disease with residual stable disease elsewhere or as the only site of progressive disease (106; 44.7%).
• Multiple sites of progressive and palliative operations (119; 50.2%).

Median overall survival was 21 months in the entire study cohort with a median follow-up of 23 months, Dr. Bello said. “Those resected to no evidence of disease (NED) – 87 patients – had an estimated 5-year overall survival of 75%.” The NED group did not reach median OS.
