The main ambition of this project is to develop, and provide the medical community, an innovative method to analyze extemporaneously, during a neurosurgery operation, excised tissues. This method is based on the analysis of the metabolic profile of excised tissues by the technique of High-Resolution Magic-Angle Spinning (HR-MAS) Nuclear Magnetic Resonance (NMR) spectroscopy. Indeed HRMAS NMR method can provide in a sufficiently short time lapse (currently about 30 minutes but within our project a time lapse of 15 min or even less is ultimately intended), medical information that can complement those obtained by classic histological examination.

Primary purpose:

The main objective of this study is to determine the sensitivity of HRMAS NMR spectroscopy in detecting residual tumor infiltration at the brain resection cavity. The investigators aim to determine the relevance of the metabolic analysis compared to histological analysis during a neurosurgery operation. This involves analyzing excised tissue samples, obtained from the operating rooms of Strasbourg University Hospitals, and Colmar Hospital Center, with no return to neurosurgeon for surgery.

Secondary purposes:

The secondary objectives of the protocol are to investigate the metabolome of different types of brain tumors, in order to find prognostic and diagnostic markers. It consists in detecting metabolomic factors of bad prognosis, and potential marker of good prognosis such as the IDH mutation.

To validate the primary endpoint of this study, statistical analysis should confirm this consistency in at least 95% of the cases.

The group of patients undergoing radiotherapy and submitted to pelvic floor muscles training.

The group of patients undergoing radiotherapy only.

The supervised muscle training will be conducted once a week with 45 minutes each session during the RT (12 weeks). In addition to the supervised sessions, patients will be instructed about the practice of home exercises and receive a guidance booklet of exercises with explanations of each exercise to be performed. These exercises must be performed daily and should be written down in the worksheet when they are performed. After this 3 month period, the patients will be encouraged to continue the exercise protocol at home without supervision. They must attend monthly to monitor adherence to home exercises.

Pelvic floor muscles training

The pelvic floor disorders are a major problem in our current society with manifestations of micturition disorders, defecatory problems and sexual dysfunction. The pelvic floor muscles training arouses interest due the few studies on this subject. Studies are being conducted with emphasis on the post-prostatectomy urinary disorders, however, not associated with radiotherapy. The study of the effect of radiotherapy in these muscles is still uncertain. At right, we do not know if the effect of radiation can trigger important anatomical changes that could lead to pelvic floor disorders manifesting clinically as defecatory and urinary disorders. These issues motivate us to research, focusing on the evaluation of these muscles through magnetic nuclear resonance considering that radiation therapy has been increasingly used as a therapeutic option in the treatment of prostate cancer. The primary objective of this is to verify the effect of pelvic floor muscles training (PFMT) tract symptoms (LUTS), anorectal and sexual complaints in men with prostate cancer (PCa) treated with radiotherapy (RT). Secondly, the objective is to evaluate the effect of PFMT in its function and in the severity of urinary incontinence (UI) and evaluate the quality of life. The assessment of the changes occurred by the effect of radiation separately and jointly to the training of the pelvic floor muscles can help us to better understand some of the dysfunctions presented in this sample of patients as well as understanding the effect and the possible contribution of training of these muscles for treatment and/or prevention of these disorders.

This present research is a randomized controlled clinical trial to be held in Clinics Hospital of Medical School of Ribeirão Preto - University of São Paulo (HCFMRP-USP) including men with confirmed diagnosis of prostate cancer by biopsy and having clinical indication for radiotherapy treatment (RT) who follow-up in the HCFMRP-USP and voluntarily consent to participate in this research. After consent, each patient must sign the consent term and then will be allocated by randomization in one of the following study groups:

* Training group (TG): the group of patients undergoing radiotherapy and submitted to pelvic floor muscles training;
* Control group (CG): the group of patients undergoing radiotherapy only. This research consists in four assessment: (1) Assessment 01: before started of radiotherapy; (2) Assessment 02: after two weeks started of RT; (3) Assessment 03: 03 months after started of RT (4) Assessment 04: 06 months after started of RT. All these assessments will be common for the participants of the research independently from the group they belong.

In each assessment, images of the pelvic floor muscles will be acquired by nuclear magnetic resonance. Parallel to the MRI, there will be a clinical assessment of the patient which consist of anamnesis and physical examination, where the assessment of pelvic floor muscle function will be tested objectively using a perineometer to evaluate the peak and the mean contraction as well as the duration of the performed sustained contraction. Data will be collected from three contractions, whose mean value will be used for this study. The myoelectric activity will be evaluated using electromyography biofeedback with electromyography anal probes. The patient will also answer a quality of life questionnaire (EORTC QLQ-C30 e PR25) and the others questionnaire: ICIQ-SF, QS-M and Jorge-Wexner Scale.

The patient of TG will be included in a supervised training protocol of the pelvic floor muscles. This protocol will be conducted in conjunction with the radiotherapy sessions.

The supervised muscle training will be conducted once a week with 45 minutes each session during the RT (12 weeks - 3 months). In addition to the supervised sessions, patients in this group will be instructed about the practice of home exercises and receive a guidance booklet of exercises with explanations of each exercise to be performed. These exercises must be performed daily and should be written down in the worksheet when they are performed. After this 3 month period, the patients will be encouraged to continue the exercise protocol at home without supervision. They must attend monthly to monitor adherence to home exercises.

The control group (CG) patients will not be instructed to perform pelvic floor exercises, instead they will only be assessed within the stipulated time.
