Arm && Interventions

Group	Intervention	Description
Case group	Samples	women with ovarian and/or endometrial cancer and weight loss will have muscle, adipose tissue, ovarian tumor and blood samples
Control group	Samples	women scheduled for an intervention for benign ovarian/ endometrial disease and no weight loss will have muscle, adipose tissue and blood samples

Primary Outcome Measures

Name	Time	Method
Measurement of muscle mitochondrial bioenergetics according to BMI	muscle biopsy realized during surgery	Measurement of muscle mitochondrial bioenergetics by high resolution oxygraphy

Secondary Outcome Measures

Name	Time	Method
on muscle biopsy	muscle biopsy realized during surgery	* Quantification of lipids on electron microscope; * Type of muscular fibers; * Analyze of gene expression and proteins involved in 1/ Mitochondrial metabolism 2/ lipid metabolism and 3/ muscular proteolysis by RTqPCR with SyBR Green and Western Blot
on ovarian cancer tumor samples	ovarian tumor biopsies realized during surgery	* lipid composition (fatty acids quantification, sterols, steroids); * RT-qPCR quantification of molecules involved in lipid metabolism (synthesis, transport) and in inflammation (immune profil and cytokines); * culture of tumour cells to evaluate resistance to chemotherapy (platinum)
on white adipose tissue	adipose tissue samples taken during surgery	adipose tissue composition (fatty acids quantification, sterols, steroids); * RT-qPCR quantification of molecules involved in lipid metabolism (synthesis, transport) and in inflammation (immune profile and cytokines); * RTqPCR analysis, western blot and immunohistochemical expression of markers of transformation into brown adipose tissue; * in specific milieu, in vitro experimentation on skeletal muscular cells
on computerized tomography	1 day of abdominal CT scan imaging procedure performed at diagnosis	assessment of body composition (fat and muscle compartments)
