Evaluation of the Inflammation-based Index as a Predictive Marker of Clinical and Radiological Response in Patients Treated With Lu-177 Oxodotreotide for Intestinal Neuroendocrine Tumour

This is a prospective, multicenter, open-label study designed to evaluate the specificity and sensitivity of the Inflammation Based Index (IBI) score as a marker for predicting clinical and radiological response in patients treated with Lu-177 oxodotreotide for inoperable or metastatic, progressive, grade 1 or 2 intestinal neuroendocrine tumors. This IBI score will be assessed on the basis of C-reactive protein (CRP) and albumin values, and will be defined as follows: * IBI = 0: Low mortality risk (if CRP and serum albumin values are considered normal in the investigator's judgment). * IBI \> 0, including: IBI = 1: Intermediate risk of mortality (if one of the two values is considered abnormal and clinically significant according to the investigator's judgment (either hypoalbuminemia or elevated CRP)); IBI = 2: High mortality risk (if both values are considered abnormal and clinically significant according to the investigator's judgment (hypoalbuminemia and elevated CRP)). Patients were followed up for 36 months. A total of 150 patients should be included in this study.

Proof of Concept to Assess the Feasibility of a Decentralised Pathway Coordinated by the Advanced Practice Nurse for Patients Receiving Oral Treatment for Cancer or Malignant Haemopathy (ACCELER PLATFORM)

This is an open-label, single-centre, category 2 "Jardé Law" proof-of-concept study designed to demonstrate the feasibility of a decentralised care pathway for patients with cancer or haematological malignancies receiving oral treatment. The study will be conducted on a population of 33 patients. In current practice, patients with certain solid cancers or haematological malignancies may be prescribed oral chemotherapy on a retroceded basis. In these cases, the oncologist (coordinating investigator) sees the patient for a consultation every 3 cycles to prescribe/renew the treatment for approximately 3 months. Every month, the patient returns to the centre to have the treatment dispensed by the hospital pharmacy. No medical consultation is associated with this visit. In this study, it is proposed to decentralise the delivery of treatment to these patients by introducing two visits to the patient's home by a service-providing nurse. The decentralised patient pathway will be organised and monitored by the Advanced Practice Nurse (APN) at the investigating centre, who will be responsible in particular for coordination with the service-providing nurse and the hospital pharmacy.

Multiomic Approach to Radioresistance of Ependymomas in Children and Adolescents

Treatment of childhood ependymoma, the second most frequent pediatric brain tumor, is based on surgery and radiation therapy. However, 50% relapse, mainly locally. Progress in imaging, molecular biology and radiotherapy ballistics has led us to propose the EPENDYMOMICS project, a multi-omics approach using artificial intelligence to detect the predictive characteristics of relapse, and to define innovative radiotherapy targets using multimodal imaging. We previously reported that the relapse sites are mainly located in the high-dose radiotherapy zone and that there appear to be prognostic factors for relapse based on anatomical and functional MRI abnormalities by diffusion and perfusion. In addition, recent studies in molecular biology have identified significant prognostic factors. The challenge now is to use and correlate all these findings in larger cohorts to tackle the radio-resistance of this disease. Our objective is to collate in a single database called NETSPARE (Network to Structure and Share Pediatric data to Accelerate Research on Ependymoma) the clinical, histological, biological, imaging and radiotherapy data from two consecutive studies that included 370 children and adolescents with ependymoma since 2000 in France. The EPENDYMOMICS project will comprise a clinical research team, three imaging research teams, two histopathology teams, and a biostatistics team working on NETSPARE. Our goal is to obtain a radiogenomic signature of our data, which will be validated with the English external cohort of 200 patients that is currently being analyzed. The perspective is to optimize the indications and volumes of irradiation that could in the future be used in a European translational research trial to tackle radioresistance.

PARa-aOrtic LymphAdenectomy in Locally Advanced Cervical Cancer

This is an international, multicenter and randomized open-label phase III study designed to demonstrate, in patients with stage IIIC1 cervical cancer, whether para-aortic lymphadenectomy followed by tailored chemoradiation is associated with increased disease-free survival compared to patients staged with FDG-PET/CT only followed by chemoradiation. The planned sample size is 510; including 200 patients in France. In this trial, patients will be assigned in one of the two following treatments arms: * Arm A (control arm): Standard chemo-radiotherapy and brachytherapy according to EMBRACE II and ESGO/ESTRO recommendations. * Arm B (experimental arm): Pretherapeutic para-aortic lymphadenectomy followed by tailored chemo-radiotherapy and brachytherapy. Considering the changing standard treatment landscape of locally advanced cervical cancer, both arms (control arm and experimental arm) may also be treated according to the INTERLACE and KEYNOTE-A18 studies, if applicable, at the discretion of the attending physician. Each patient will be followed up for 5 years. A cost-utility study will be performed in patients included in France. Other countries could be involved in this specific study. It will assess the incremental cost-utility ratio (cost per QALY gained) of para-aortic lymphadenectomy followed by tailored chemo-radiation in patients with positive PALN compared to patients staged with PET/CT only followed by chemo-radiation. This study also has ancillary objectives: * Biologic: To study T cell exhaustion, immune changes during chemoradiation, HPV ctDNA dynamic evolution, and the par-aortic lymph node as a premetastatic niche. * Radiomics: To study the contribution of radiomics and FDG-PET/CT metabolic parameters to predict para-aortic lymph node involvement and clinical outcome. * Senti-PAROLA: To evaluate the accuracy (Sensitivity, specificity, positive and negative predictive value) of the para-aortic sentinel lymph node (SPA) for PALN staging, and to evaluate the prognostic value of low volume metastasis of SPA.

Prostate Cancer Burden and Heterogeneity Evaluation Towards Liquid Biopsy: a Correlation Study to 18FDCFPyL PET and Patients Outcome

This is a prospective, monocentric, proof of concept study aims to identify in prostate cancer patients, a potential relationship between CTC-PSMA positivity and 18F-PET-PSMA results as well as patient outcome. Patients with 18F-PET-PSMA indication will perform imaging extension work-up as part of current practice. If they agree to participate in the study, a blood sample will be performed prior to the 18F-PET-PSMA standard imaging (T1). In order to evaluate the potential relationship between CTC-PSMA and 18F-PET-PSMA imaging, the study will be presented to all patients seen in consultation for an extension workup for prostate cancer. This will allow to analyze the results in patients with different level of tumor burden afterward to define the following three groups based on imaging results: Group 1 : no tumor volume Negative 18F-PET-PSMA (patients without uptake lesion) Group 2 : low or medium tumor volume Positive 18F-PET-PSMA (patients with an uptake in prostate bed or with an oligo-metastatic extension (number of lesions \< 6)) Group 3 : high tumor volume Positive 18F-PET-PSMA (patients with a polymetastastatic extension (number of lesions ≥ 6)). In each of these groups, the rate of patients with positive PSMA CTC will be analyzed (i.e. patient having at least one CTC-PSMA positive). For patients with an indication of treatment by 177LuPSMA-617 (PLUVICTO®) according to standard practices, additional blood samples will also be collected at the following time points: 2nd cycle (T2) and 4th cycle of treatment (T3), just before injection. For these patients, data will be collected up to 6 months after the last treatment injection (clinical and biological data; results of tumor assessments based on 18F-PET-PSMA imaging).
