-Summary
Pelvic chemoradiotherapy (CRT) is an effective treatment for Locally Advanced Cervical Cancer (LACC). However, CRT induces premature ovarian failure ceasing the production of ovarian hormones. This may lead to severe consequences to the patient's life quality, sexuality and overall healthy. An acceptable treatment to minimize the adverse effects caused by the lack of ovarian hormones is hormonal replacement but less than 40% of the patients younger than 50 years have access to this treatment. A second alternative treatment is ovarian transposing which is a surgical technique with variable success rate depending on how far the ovaries are from the radiotherapy field. A third, more promising, alternative is involves using autologous ovarian tissue as a graft in tissues far from the radiotherapy field. This treatment has the potential of maintaining the natural ovarian hormones production at a lower-cost and requiring a simpler procedure. The primary objective of this randomized phase 1-2 clinical trial is to validate the feasibility of ovarian tissue engraft into fatty tissue and its endocrine functionality.

- Ovarian graft (Procedure), also known as Autologous Heterotopic Fresh Ovarian Graft: Before the beginning of pelvic radiotherapy, one of the ovaries will be removed by laparoscopy. Ovary slices of 1-2 mm will be prepared in sterile environment and engrafted in the fatty tissue of inner tight. One representative fragment will undergo histologic evaluation. These procedures will be done in the same surgical time.
+Outcome measures
Primary outcomes
- Dosage of serum levels of follicle stimulating hormone (FSH) in mUI/ml in intervention (engraft of ovarian tissue into fatty tissue) and control groups. Dosage will be performed at baseline and post radiotherapy (2, 6, 12 and 24 months). [2 years]: Endocrine functionality is defined as FSH levels under 25 mUI/ml.
- Dosage of serum levels of estradiol in pg/ml in intervention (engraft of ovarian tissue into fatty tissue) and control groups. . Dosage will be performed at baseline and post radiotherapy (2, 6, 12 and 24 months). [2 years]: Endocrine functionality is defined as estradiol upper 47 pg/mL.
Secondary outcomes
- Dosage of serum levels of glucose in mg/dL in intervention and control groups. (Time frame: At baseline and post radiotherapy month 2, 6, 12 and 24). [2 years]: Evaluation of glucose metabolism.
- Measure of serum glycated hemoglobin in percentage in intervention and control groups. (Time frame: At baseline and post radiotherapy month 2, 6, 12 and 24). [2 years]: Evaluation of glucose metabolism.
- Measure of serum levels of cholesterol in mg/dL in intervention and control groups. (Time frame: At baseline and post radiotherapy month 2, 6, 12 and 24). [2 years]: Evaluation of lipid metabolism.
- Measure of serum levels of triglycerides in mg/dL in intervention and control groups. (Time frame: At baseline and post radiotherapy month 2, 6, 12 and 24). [2 years]: Evaluation of lipid metabolism.
- Evaluate the changes in bone mineral density (BMD) in femoral neck and lumbar spine by bone densitometry, evaluating T and Z scores standard deviation (SD) in intervention and control groups. Time frame: At baseline and post radiotherapy month 12 and 24. [2 years]
- Bioimpedance monitoring to evaluate changes in body composition by fat and lean mass percentage in intervention and control groups. Time frame: At baseline and post radiotherapy month 12 and 24). [2 years]
- Quantification of body mass index reported in kg/m2 in intervention and control groups. Time frame: At baseline and post radiotherapy month 12 and 24). [2 years]: Evaluation of changes in body mass.
- Score life quality in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ C30) in intervention and control groups. [2 years]: EORTC QLQ C30 was developed and validated to assess the quality of life of cancer patients.
The 30-item EORTC QLQ-C30 is a disease-specific measure that assesses multiple QoL domains in patients with cancer. There are five functioning scales that measure physical, role, emotional, cognitive, and social functioning. Three symptom scales measure fatigue, pain, and nausea/vomiting.
- Score life quality in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 Cervical Cancer Module (EORTC QLQ C30 CX24) in intervention and control groups. [2 years]: EORTC QLQ-CX24 Scoring Manual The Cervical Cancer Module is a supplementary questionnaire module to be employed in conjunction with the QLQ-C30. The EORTC QLQ-CX24 was designed to assess disease-specific and treatment-specific aspects of QoL in patients with cervical cancer.
