Summary

In this episode of Melanoma Matters, host James Larkin uses his 1-800-Operator voice until co-host Sapna Patel reminds him to use his podium voice. There is a noisy wardrobe choice (SP) and a fact check of a fact check (JL).

Sapna and James have an in-depth conversation of the Checkmate 511 study, discussing its implications for treatment regimens in melanoma. They delve into the nuances of type 1 and type 2 errors, analyze the results of the study, and consider the long-term follow-up data. The conversation also explores global perspectives on treatment practices and the importance of understanding toxicity and efficacy in clinical settings.
