Méthode permettant de poser un pronostic de bénéfice clinique chez un individu atteint d'une tumeur, et englobant les opérations suivantes: dans un échantillon de sang dudit individu, (a1) détermination du nombre de lymphocytes, et/ou (a2) du nombre de neutrophiles; et (b1) identification de l'individu comme présentant un bon pronostic de bénéfice clinique si le nombre de lymphocytes est supérieur à un niveau de base de lymphocytes de 1,4 à 1,8 x 109 par litre de sang, en particulier inférieur ou égal à 1,6 x 109; ou (b2) identification de l'individu comme présentant un bon pronostic d'amélioration clinique si le nombre de neutrophiles est inférieur ou égal à un niveau de base de4,0 à 6,0 x 109 par litre de sang, en particulier inférieur ou égal à 5,0 x 109; ou (b3) identification de l'individu comme présentant un mauvais pronostic d'amélioration clinique si le nombre de lymphocytes est inférieur ou égal à un niveau de base de 1,4 à 1,8 x 109 par litre de sang, en particulier inférieur ou égal à 1,6 x 109, et si le nombre de neutrophiles est supérieur au niveau de base de 4,0 à 6,0 x 109 par litre de sang, en particulier supérieur à 5,0 x 109.
