They further show that AKT2 drives a large part of the phenotype. In addition, they demonstrate for the first time that a single PIK3CA mutation induces metabolic reprogramming with the Warburg effect and protein and lipid synthesis—hallmarks of cancer cells—in vitro, in vivo and in patients. They finally show that alpelisib, an approved PIK3CA inhibitor in oncology, is efficient at preventing and improving PIK3CA-adipose tissue overgrowth and reversing metabolomic anomalies in both animal models and patients. Accordingly, the present invention relates to an in vitro method for monitoring the efficiency of a PI3K inhibitor treatment in a subject in need thereof comprising the step of determining the level of at least one metabolite selected in the group consisting of cis-aconitate, succinic acid, 5-methylcytosine, acetyl-carnitine, acetyl-lysine, argininosuccinate, betaine, butyric acid, carnitine, creatine, glucose, glycine, hexanoyl-carnitine, L-fucose, lactate, L-dihydroorotic acid, linolenic acid, nicotinamide N-oxide, palmitoyl-carnitine, panthotenate, pyruvate, quinolinic acid, tryptophan, urate, in a biological sample obtained from the subject.
