Skeletal Muscle Energy Metabolism in Women With Weight Loss and Ovarian and/or Endometrial Cancer With Weight Loss (METERMUS-IMC)

Study of Differences in Skeletal Muscle Energy Metabolism Alterations in Women With Weight Loss and Ovarian and/or Endometrial Cancer Based on the Body Mass Index

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Measurement of muscle mitochondrial bioenergetics according to BMI	Measurement of muscle mitochondrial bioenergetics by high resolution oxygraphy	muscle biopsy realized during surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
