On the set of C to you, Anne-Elisabeth Lemoine received Professor Nicolas Girard, pulmonologist specializing in thoracic oncology and head of the Curie-Montsouris Thorax Institute. He came to inform after the testimony of singer Florent Pagny in seven to eight on TF1 Sunday March 5, 2023 which told that he had made the choice not to have followed the treatment protocol to the end and not to have benefited from immunotherapy. A choice he regrets today because it could make him relapse. Professor Nicolas Girard therefore returned to the importance of immunotherapy and the fact of continuing, whatever happens, his treatment until the end, despite the harshness of the latter.
